Cable guiding device
A cable guiding device includes a base, upper and lower guide members disposed along a longitudinal direction, in which two ends of the upper guide member are mounted on the base and two ends of the lower guide member are mounted on the base. A slider defining a central cavity is penetrated therethrough in a lateral direction substantially perpendicular to the longitudinal direction. Upper and lower movable members are fitted slidably over the upper and lower guide members respectively, in which two ends of the upper movable member are mounted on two longitudinal side walls of the slider, and two ends of the lower movable member are mounted on two longitudinal side walls of the slider respectively. Upper and lower guiding rollers are fitted rotatably over the upper and lower movable members and disposed within the central cavity respectively.
1. A cable guiding device, comprising:
a base,
an upper guide member disposed along a longitudinal direction, in which two ends of the upper guide member are mounted on the base respectively,
a lower guide member disposed parallelly under the upper guide member and spaced apart from the upper guide member in a vertical direction, in which two ends of the lower guide member are mounted on the base respectively,
a slider defining a central cavity penetrated therethrough in a lateral direction substantially perpendicular to the longitudinal direction,
an upper movable member fitted slidably over the upper guide member, in which two ends of the upper movable member are mounted on two longitudinal side walls of the slider respectively,
an upper guiding roller fitted rotatably over the upper movable member and disposed within the central cavity,
a lower movable member fitted slidably over the lower guide member, in which two ends of the lower movable member are mounted on two longitudinal side walls of the slider respectively, and
a lower guiding roller fitted rotatably over the lower movable member and disposed within the central cavity.
2. The cable guiding device as set forth in claim 1 , further including:
a left guiding roller rotatable around an axis thereof, in which upper and lower ends of the left guiding roller are mounted on top and bottom walls of the slider respectively; and
a right guiding roller rotatable around an axis thereof, in which upper and lower ends of the right guiding roller are mounted on the top and bottom walls of the slider respectively,
wherein the left and right guiding rollers are spaced a predetermined distance apart from each other in the longitudinal direction and disposed in front of the upper and lower guide members in the lateral direction, wherein a longitudinal size of the central cavity is larger than the predetermined distance.
3. The cable guiding device as set forth in claim 2 , wherein axes of the upper and lower guide members are located in the same vertical plane, and axes of the left and right guiding rollers are located in the same longitudinal plane and parallel to each other.
4. The cable guiding device as set forth in claim 2 , wherein two first lugs are formed on a front side of the top wall of the slider, extended forwardly in the lateral direction, and spaced apart from each other,
two second lugs are formed on a front side of the bottom wall of the slider, extended forwardly in the lateral direction, and spaced apart from each other, and correspond to the two first lugs respectively, and
upper ends of the left and right guiding rollers are mounted on the two first lugs and lower ends of the left and right guiding rollers are mounted on the two second lugs, respectively.
5. The cable guiding device as set forth in claim 1 , wherein each of the upper and lower movable members includes a linear bearing.
6. The cable guiding device as set forth in claim 1 , wherein the base includes:
a mounting plate, and
first and second extending frames which are extended upwardly in the vertical direction from the mounting plate respectively and spaced apart from each other in the longitudinal direction,
wherein two ends of each of the upper and lower guide members are mounted on the first and second extending frames respectively.
7. The cable guiding device as set forth in claim 6 , further including:
first and second support frames which are mounted on the first and second extending frames respectively,
wherein two ends of each of the upper and lower guide members are mounted on the first and second support frames respectively.
8. The cable guiding device as set forth in claim 1 , further including a cable-pressing roller rotatably disposed in the central cavity of the slider along the longitudinally direction, and movable between a tension position at which the cable-pressing roller tensions the cable and a release position at which the cable-pressing roller release the cable.
9. The cable guiding device as set forth in claim 8 , wherein a vertical groove is formed in each of the two longitudinal side walls of the slider, and two ends of the cable-pressing roller are supported in the vertical grooves respectively.
10. The cable guiding device as set forth in claim 9 , wherein a plurality of recesses are formed in a side wall of each vertical groove and spaced apart from one another in the vertical direction, and
wherein two ends of the cable-pressing roller are supported and held in the recesses respectively when the cable-pressing roller is located at the tension position and the release position.
