Hose clamp structure and working machine

1 . A hose clamp structure comprising:

a vertical plate having an opening;

a groove portion provided at a back side of the vertical plate on one of opposite sides of the opening in a plate-surface parallel direction such that the groove portion is adjacent to the opening, the groove portion being open toward the opening in the plate-surface parallel direction;

a receiver portion provided at the back side of the vertical plate on the other of the opposite sides of the opening in the plate-surface parallel direction;

a first clamping member to be inserted in the groove portion;

a second clamping member made of an elastic member and configured such that the second clamping member is placed in the receiver portion through the opening from a front side of the vertical plate to contact the receiver portion with the first clamping member being inserted in the groove portion and such that at least one hose passing through the opening is held between the first clamping member and the second clamping member; and

a pressing member to be attached to the vertical plate;

wherein the pressing member includes a main plate to be inserted in the opening to contact the second clamping member, and an attachment plate fixed to the main plate and attached to the vertical plate, the pressing member being configured such that the attachment plate is attached to the vertical plate by a bolt inserted through the attachment plate and the vertical plate in a direction perpendicular to a front surface of the vertical plate from the front side of the vertical plate with the attachment plate overlapping the front surface of the vertical plate to cause the main plate to press the second clamping member from the front side of the vertical plate to elastically deform the second clamping member, to cause the second clamping member to press the first clamping member.

2 . The hose clamp structure according to claim 1 , wherein the groove portion includes a first portion which is a portion of the vertical plate that defines one of opposite edges of the opening in the plate-surface parallel direction, a second portion facing the first portion at the back side of the vertical plate, and a third portion extending from one of opposite edges of the second portion in the plate-surface parallel direction toward a back surface of the vertical plate and fixed to the vertical plate.

3 . The hose clamp structure according to claim 1 , wherein

the receiver portion includes a first wall portion facing the opening at the back side of the vertical plate, and a second wall portion extending from one of opposite edges of the first wall portion in the plate-surface parallel direction toward a back surface of the vertical plate and fixed to the vertical plate; and

the second clamping member is placed to contact the first wall portion and the second wall portion through the opening from the front side of the vertical plate.

4 . A working machine comprising:

a machine body;

a prime mover on the machine body;

a partition wall to separate a prime mover chamber housing the prime mover from an outside of the prime mover chamber; and

the hose clamp structure according to claim 1 ; wherein

the vertical plate defines a portion of the partition wall; and

the at least one hose is guided from the prime mover chamber to an outside of the partition wall.

5 . A hose clamp structure, comprising:

a vertical plate having an opening;

a groove portion provided at a back side of the vertical plate on one of opposite sides of the opening in a plate-surface parallel direction such that the groove portion is adjacent to the opening, the groove portion being open toward the opening in the plate-surface parallel direction;

a receiver portion provided at the back side of the vertical plate on the other of the opposite sides of the opening in the plate-surface parallel direction;

a first clamping member to be inserted in the groove portion;

a second clamping member made of an elastic member and configured such that the second clamping member is placed in the receiver portion through the opening from a front side of the vertical plate to contact the receiver portion with the first clamping member being inserted in the groove portion and such that at least one hose passing through the opening is held between the first clamping member and the second clamping member; and

a pressing member to be attached to the vertical plate to press the second clamping member from the front side of the vertical plate to elastically deform the second clamping member to cause the second clamping member to press the first clamping member;

wherein

the first clamping member has a thickness substantially equal to a groove width of the groove portion;

the second clamping member has a thickness such that the second clamping member protrudes forward through a back surface of the vertical plate via the opening when the second clamping member is in contact with the receiver portion but is not pressed by the pressing member; and

the pressing member includes a main plate to be inserted in the opening to press the second clamping member, and an attachment plate fixed to the main plate to contact a front surface of the vertical plate and attached to the vertical plate.

6 . A hose clamp structure, comprising:

a vertical plate having an opening;

a groove portion provided at a back side of the vertical plate on one of opposite sides of the opening in a plate-surface parallel direction such that the groove portion is adjacent to the opening, the groove portion being open toward the opening in the plate-surface parallel direction;

a receiver portion provided at the back side of the vertical plate on the other of the opposite sides of the opening in the plate-surface parallel direction;

a first clamping member to be inserted in the groove portion;

a second clamping member made of an elastic member and configured such that the second clamping member is placed in the receiver portion through the opening from a front side of the vertical plate to contact the receiver portion with the first clamping member being inserted in the groove portion and such that at least one hose passing through the opening is held between the first clamping member and the second clamping member; and

a pressing member to be attached to the vertical plate to press the second clamping member from the front side of the vertical plate to elastically deform the second clamping member to cause the second clamping member to press the first clamping member;

wherein the vertical plate has an insertion groove extending from an outer edge of the vertical plate toward the opening to communicate with the opening and configured to allow the at least one hose to pass through the insertion groove in a direction perpendicular to a longitudinal direction of the at least one hose.
