DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] As shown in the accompanying drawings, the utility model is a transmission structure of a straight lock, comprising a bottom shell 1, a transmission plate 2, a shift fork 3 and two push pieces 4, the two push pieces 4 are respectively arranged at both ends of the bottom shell 1, the bottom shell 1 is equivalent to the existing bottom cover plate, the existing bottom cover plate is flat, and the bottom shell 1 is U-shaped as shown in the figure, with a groove 10 formed in the middle, and the two side walls of the groove 10 are arranged from top to bottom with a first slide groove 101, a second slide groove 102 and a third slide groove 103 parallel to each other. It should be noted that from top to bottom, it is arranged in sequence from the groove mouth of the groove 10 to the groove bottom, and the three slide grooves are arranged in parallel with each other. The three slide grooves are formed by three partitions arranged in the groove 10 at intervals and matched with the groove bottom of the groove 10. The height of the three slide grooves corresponds to the height of the transmission plate 2, the slide plate 31 and the push piece 4. The transmission plate 2, the shift fork 3 and the push piece 4 are all arranged in the bottom shell 1. The transmission plate 2 is linearly slidably arranged in the first slide groove 101, and both sides of the two push members 4 are protrudingly provided with sliders 41 that slide linearly in the second slide groove 102. The fork 3 includes a slide plate 31 that slides linearly in the third slide groove 103. The transmission structure is a slidable structure in the one-way lock. Generally, the transmission structure of the one-way lock includes but is not limited to three major parts: the push member 4, the transmission plate 2 and the fork 3. Because they need to be overlapped and fixed to each other, it is difficult to install the push member 4, the transmission plate 2 and the fork 3 on the same plane. The fork 3 can be directly installed on the transmission plate 2. The other end of the transmission plate 2 is the push member 4, and also includes a handle 111, that is, a shell used to cover the outside of the one-way lock to hide the internal structure. The length of the handle 111 is less than the distance between the two push members 4, so that the one-way lock keeps any push member 4 exposed.

[0022] The utility model discloses a transmission structure of a straight lock. A groove 10 is arranged on a bottom shell 1, and a first slide groove 101, a second slide groove 102 and a third slide groove 103 are respectively arranged on two side walls of the groove 10 according to three major parts of a transmission plate 2, a shift fork 3 and a push piece 4 of the transmission structure, and are respectively linearly slidably connected to the transmission plate 2, the push piece 4 and a slide plate 31, so as to limit the positioning of the transmission structure, prevent the displacement of the transmission structure during the movement, improve the stability and smoothness of the transmission structure when sliding, better protect the straight lock and prevent the damage thereof.

[0023] In this embodiment, the thickness of the sliding plate 31 corresponds to the groove width of the third sliding groove 103. Air cushions 310 are provided on both sides of the sliding plate 31 and are tightly pressed against the bottom of the third sliding groove 103 through the air cushions 310, which is convenient for installation. At the same time, the sound of friction during the sliding of the fork 3 can be reduced. The air cushions 310 are made of plastic material and are in a circular ring shape, having a certain deformation ability. The distance between the two air cushions 310 on both sides is slightly larger than the distance between the two side walls of the groove 10, which can further make the air cushions 310 tightly pressed against the bottom of the third sliding groove 103, thereby assisting in fixing the fork 3 and preventing the fork 3 from dropping at the corners and sagging.

[0024] In this embodiment, the two push buttons 4 include a pressing part 44 protruding outside the bottom case 1. The width of the slider 41 corresponds to the groove width of the second sliding groove 102, which prevents the push button 4 from deviating horizontally from the sliding direction. And the pressing part 44 can abut against the bottom case 1. When one of the push buttons 4 is pressed, the pressing part 44 on the push button 4 abuts against the bottom case 1, and the fork 3 completes the stroke of a single movement.

[0025] In this embodiment, the thickness of the transmission plate 2 corresponds to the groove width of the first sliding groove 101, and the width of the transmission plate 2 corresponds to the groove width of the groove 10. By using the linear sliding fit between the first sliding groove 101 and the transmission plate 2, it is realized to prevent the transmission plate 2 from deviating horizontally from the sliding direction when sliding.

[0026] In this embodiment, for the transmission structure of the single-sided lock, in addition to the transmission plate 2, the fork 3, and the push button 4, there is also an anti-sagging component 5 provided inside the bottom case 1. If a single-sided lock with an anti-sagging function needs to be added, the two push buttons 4 are both connected to the anti-sagging component 5 through the transmission plate 2. The fork 3 is installed and clamped and fixed on the anti-sagging component 5 through the sliding plate 31. The anti-sagging component 5 is a connecting block for connecting the transmission plate 2 and the fork 3. By pressing one of the push buttons 4, the push button 4 pushes the anti-sagging component 5 through the transmission plate 2, and then the anti-sagging component 5 is used to move the fork 3 up and down. For reference to the existing structure, if there is an anti-sagging structure, the anti-sagging component 5 includes the anti-sagging structure. Because the transmission principle is the same, it also requires the anti-sagging component 5 to drive the fork 3 to move up and down to unlock or lock, so it is also connected to the push button 4 through the transmission plate 2; a fixed box 6 is fixed inside the bottom case 1, a through groove is provided inside the fixed box 6, the anti-sagging component 5 is slidably arranged in the through groove, and the fixed box 6 is provided with a hook edge part 61 on both sides of the through groove for preventing the anti-sagging component 5 from disengaging. The fixed box 6 hooks the anti-sagging component 5 through the hook edge part 61 to prevent the anti-sagging component 5 from disengaging when sliding, and further prevent the anti-sagging component 5 from sliding and deviating.

[0027] The above embodiments are the preferred embodiments of the present invention. All structures similar to the present invention and equivalent changes made thereto shall fall within the protection scope of the present invention.
