Externally-mounted holing-free mounting mechanism for curtain
View Patent ↗The present invention provides an electronic cymbal which comprises an externally-mounted holing-free mounting mechanism for a curtain, comprising a cross beam exposed out of a window frame, a first mounting assembly and a second mounting assembly; the first mounting assembly and the second mounting assembly are supported in the window frame in cooperation with the cross beam, and both the first mounting assembly and the second mounting assembly are in slide cooperation with the cross beam. The length of the cross beam is greater than a width of the window frame, the curtain assembled on the cross beam can fully cover the entire window frame without light leakage. In addition, the first mounting assembly and the second mounting assembly are arbitrarily slidable on the cross beam, and thus, it is applicable to the window frames of multiple widths.
1. An externally-mounted holing-free mounting mechanism for a curtain, comprising a cross beam exposed out of a window frame, a first mounting assembly and a second mounting assembly, wherein the first mounting assembly and the second mounting assembly are supported in the window frame in cooperation with the cross beam, and both the first mounting assembly and the second mounting assembly are in slide cooperation with the cross beam; the first mounting assembly and the second mounting assembly both are provided with a locking piece for locking up the first mounting assembly and the second mounting assembly onto the cross beam; at least one of the first mounting assembly and the second mounting assembly is provided with an adjustment assembly for holding the first mounting assembly and the second mounting assembly in the window frame;
the first mounting assembly comprises a first slide seat and a first holding block, the first holding block is integrally connected with the first slide seat, and the first slide seat is in slide connection with the cross beam, the second mounting assembly comprises a second slide seat and a second holding block, the second slide seat is in slide connection with the cross beam, a mounting cabin is disposed on the second slide seat, and the second holding block is in movable cooperation with the mounting cabin through the adjustment assembly; and
the adjustment assembly is mounted inside the mounting cabin; the adjustment assembly comprises a drive piece, a linkage piece, a locking block, a first elastic piece, and a second elastic piece; the second holding block is provided with a central shaft penetrating through the mounting cabin; the first elastic piece, the linkage piece and the second elastic piece are sequentially sleeved on the central shaft; the first elastic piece is close to the second holding block; the drive piece and the linkage piece are vertically crossed and linked cooperatively; at least one end of the drive piece is in communication with outside of the mounting cabin; the locking block is in thread-sleeving cooperation with the linkage piece; and an end of the central shaft is connected with a screw and a washer.
2. The externally-mounted holing-free mounting mechanism for a curtain of claim 1 , wherein the cross beam is provided with a slide track which penetrate through both ends of the cross beam along a length of the cross beam, the first slide seat and the second slide seat opposed to each other are slidably connected to the slide track, and the locking pieces are connected to the first slide seat and the second slide seat respectively to lock the first slide seat and the second slide seat onto the slide track.
3. The externally-mounted holing-free mounting mechanism for a curtain of claim 1 , wherein the drive piece is a worm rod, and the linkage piece comprises a worm gear portion and a screw rod portion; the worm rod is in vertical engagement transmission with the worm gear portion, and the worm gear portion is in engagement transmission with the screw rod portion through an end surface gear ring; the locking block is thread-sleeved on the screw rod portion; the locking block crawls along the threads of the screw rod portion along with the rotation of the screw rod portion, and a through hole for exposing the ends of the worm rod is opened in the mounting cabin.
4. The externally-mounted holing-free mounting mechanism for a curtain of claim 3 , wherein a limiting portion is disposed inside the mounting cabin, and an annular stepped surface abutted against the limiting portion is disposed on the screw rod portion; an end of the first elastic piece is abutted against an end of the screw rod portion away from the annular stepped surface, and the other end of the first elastic piece is abutted against the second holding block; the first elastic piece is in a compressed state and an end of the first elastic piece squeezes the screw rod portion, and the limiting portion axially blocks the screw rod portion, and the other end of the first elastic piece squeezes the second holding block, and the second holding block partially protrudes out of the mounting cabin, and the washer at the end of the central shaft blocks the outer end surface of the mounting cabin.
5. The externally-mounted holing-free mounting mechanism for a curtain of claim 4 , wherein an end of the second elastic piece is abutted against an end of the worm gear portion away from the screw rod portion, and the other end of the second elastic piece is abutted against an inner end surface of the mounting cabin; the second elastic piece is in a compressed state so as to squeeze the worm gear portion to be engaged with the screw rod portion.
6. The externally-mounted holing-free mounting mechanism for a curtain of claim 1 , wherein a cavity penetrating through both ends of the cross beam is disposed inside the cross beam, and both ends of the cavity are used for inserting first and second mounting assemblies.
