[0036] The mounting plate 3 is fixedly connected with a positioning block 301 at the top, a limiting hole 302 is formed in one side of the positioning block 301, a connecting rod 201 is fixedly connected with the fixed block 2 at one side, the connecting rod 201 penetrates through the limiting hole 302 at one end and is fixedly connected with a limiting block 202, when the drawer 1 is in an open state, the weight of the drawer 1 and the articles in the drawer 1 applies pressure to one end of the connecting rod 201 through the fixed block 2, so that the other end of the connecting rod 201 is raised upward, and at this time the positioning block 301 limits the connecting rod 201, thereby providing a supporting force for the drawer 1 through the connecting rod 201 to prevent the drawer 1 from being lowered and deformed.

[0037] The bottom of the fixed block 2 is provided with a spring groove 203, spring sheets 204 are fixedly installed on the inner wall of the spring groove 203 at one side, a slot 205 is formed in one side of the fixed block 2, a pull block 206 is arranged in the slot 205, the pull block 206 extends into the spring groove 203 at one end, and a clamping block 207 is fixedly connected to the bottom of the pull block 206, and the top of the mounting plate 3 is provided with a clamping groove 303, in use, the pull block 206 at one side of the pull plate 101 is pulled upward to extrude the spring sheets 204 and make the clamping block 207 move into the spring groove 203, and then the pull plate 101 is pushed to drive the drawer 1 and the upper slide rail 6 at the bottom of the drawer 1 to slide in the lower slide rail 5, at this time, the connecting sheet 404 pulls one end of the constant force spring 403 to make the constant force spring 403 expand until the lower slide rail 5 moves to the terminal of the upper slide rail 6, then the pull block 206 is released to release the spring sheets 204, the spring sheets 204 apply a downward pressure to the pull block 206 to drive the pull block 206 and the clamping block 207 to move downward, so that the clamping block 207 is clamped into the clamping groove 303 to fix the drawer 1 in the furniture.

[0038] The working principle is as follows:

[0039] In use, the pull block 206 at one side of the pull plate 101 is pulled upward to extrude the spring sheets 204 through the pull block 206, so that the clamping block 207 moves into the spring groove 203, and at the same time the pull plate 101 is pushed to drive the drawer 1 and the upper slide rail 6 at the bottom of the drawer 1 to slide in the lower slide rail 5, at this time, the connecting sheet 404 pulls one end of the constant force spring 403 to make the constant force spring 403 expand and elastically deform, and convert kinetic energy into elastic potential energy, until the lower slide rail 5 moves to the terminal of the upper slide rail 6, at this time, the pull block 206 is released to release the spring sheets 204, the spring sheets 204 apply a downward pressure to the pull block 206 to drive the pull block 206 and the clamping block 207 to move downward, so that the clamping block 207 is clamped into the clamping groove 303 to fix the drawer 1 in the furniture.

[0040] When the drawer 1 needs to be opened, the pull block 206 can be pulled upward to extrude the spring sheet 204, so that the clamping block 207 is away from the clamping groove 303, the constant force spring 403 is released, the elastic potential energy stored in the constant force spring 403 is converted into kinetic energy, the drawer 1 and the upper slide rail 6 are moved to the other end of the lower slide rail 5, so that the drawer 1 is moved out of the furniture, and because the gear on the damping gear 4 is meshed and connected with the teeth on the bottom of the upper slide rail 6, when the drawer 1 is opened, the damping gear 4 will start a certain buffering effect, limit the opening speed of the drawer 1, prevent it from suddenly popping out, and when the drawer 1 is pushed to move into the furniture for resetting, the damping gear 4 will also provide a force in the opposite direction, to ensure that the drawer 1 is stably and slowly closed, avoiding the impact between the drawer 1 and the furniture and producing noise.

[0041] Further, when the drawer 1 is in the open state, the weight of the drawer 1 and the items inside the drawer 1 exerts pressure on one end of the connecting rod 201 through the fixed block 2, so that the other end of the connecting rod 201 is raised upward, and at this time the positioning block 301 limits the connecting rod 201, thereby providing a supporting force for the drawer 1 through the connecting rod 201 to prevent the drawer 1 from driving the upper slide rail 6 to drop and deform.

[0042] In addition, through the arrangement of the connecting piece 305, the entire drawer structure can be fixed in the furniture.
