[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 , Figure 2As shown, an anti-pinch cabinet door comprises a frame 2 fixed in an opening of a cabinet 1, a sliding door 3 slidably arranged in the frame 2, the bottom and top of the frame 2 are provided with slide rails, the top and bottom of the sliding door 3 are provided with pulleys matched with the slide rails, the sliding door 3 is connected to a transmission mechanism 4 located in the cabinet 1, the transmission mechanism 4 is connected to a damping mechanism 5, when the sliding door 3 moves to the two ends close to the frame 2, the damping mechanism 5 provides sliding resistance so that the sliding door 3 and the frame 2 are slowly fitted;

[0019] When the sliding door 3 slides along the slide rail, when the sliding door 3 approaches the two ends of the slide rail, the sliding door 3 acts on the damping mechanism 5 through the transmission mechanism 4. Under the action of the damping mechanism 5, the sliding speed of the sliding door 3 is reduced, but it does not affect the continued sliding of the sliding door 3 to achieve a fully opened and fully closed state, thereby avoiding the situation where the sliding door 3 is too fast when opening and closing the sliding door 3, causing the operator to not have time to remove the hand from between the sliding door 3 and the frame 2, and effectively avoiding the hand pinching phenomenon;

[0020] Specifically, Figure 4 As shown, the damping mechanism 5 includes a cylinder 501 fixedly arranged in the cabinet 1 and filled with viscous liquid, a piston 502 is arranged in the cylinder 501, a throttle hole 503 connecting the two sides is arranged on the piston 502, a piston rod 504 penetrating the cylinder 501 is connected to one side of the piston 502, and the piston rod 504 is connected to the transmission mechanism 4;

[0021] When the piston rod 504 is pushed slowly, the viscous liquid in the cylinder body 501 will flow from one side of the piston 502 to the other side. When the piston rod 504 is pushed at a faster speed, the movement of the piston 502 will encounter greater resistance.

[0022] Specifically, Figure 3 As shown, the transmission mechanism 4 includes a slide bar 401 slidably arranged in the cabinet 1, the slide bar 401 is connected to the slide door 3 and moves with the slide thereof, and two trigger blocks 402 are fixedly arranged on the slide bar 401, and the two trigger blocks 402 respectively generate opposite forces on the piston rod 504 when the slide door 3 approaches the two sides of the frame 2;

[0023] In order to make the mutual cooperation movement between the sliding door 3, the sliding rod 401, and the piston rod 504 smoother, in a further embodiment, the piston rod 504 and the sliding rod 401 move along their axial direction and the movement route is parallel to the movement route of the sliding door 3;

[0024] A sleeve 403 is movably sleeved on the slide rod 401, and two ends of the sleeve 403 can respectively contact the two trigger blocks 402, and the sleeve 403 is fixedly connected to the piston rod 504;

[0025] like Figure 1 , Figure 2 As shown, when the sliding door 3 is at one side of the frame 2, one of the trigger blocks 402 contacts one end of the sleeve 403, and at this time the piston 502 is located at one end of the cylinder 501. When the sliding door 3 is pushed to move toward the other side of the frame 2, the trigger block 402 contacting one end of the sleeve 403 begins to move away from the sleeve 403, and the other trigger block 402 gradually approaches the other end of the sleeve 403. In this process, the sliding door 3 can slide at a faster speed to ensure the efficiency of opening or closing the door.

[0026] When the distance between the sliding door 3 and the frame 2 reaches the critical position of pinching the hand, the trigger block 402 contacts the sleeve 403. At this time, the resistance of the liquid in the cylinder 501 to the piston 502 is transmitted to the sleeve 403 through the piston rod 504, and the sleeve 403 slows down the speed of the sliding door 3 through the sliding rod 401.

[0027] At the same time, when the sliding door 3 is completely moved to the other side, the sliding door 3 acts on the sleeve 403 through the sliding rod 401 and the trigger block 402, pushing the piston 502 to the other end of the cylinder body 501, and when the sliding door 3 slides back to this side, it can produce a damping effect on the sliding of the sliding door 3;

[0028] In order to improve the balance of the force exerted by the damping mechanism 5 on the slide bar 401, in a further embodiment, the damping mechanism 5 is provided with two groups and is respectively located on both sides of the sleeve 403, and the two groups of the damping mechanism 5 are symmetrically arranged about the axis of the slide bar 401;

[0029] Specifically, a slide groove 201 is provided at the bottom of the frame 2, the transmission mechanism 4 and the damping mechanism 5 are arranged below the slide groove 201, a slider 301 is fixedly connected to the bottom of the sliding door 3, and the slider 301 passes through the slide groove 201 and is connected to the transmission mechanism 4;

[0030] In this embodiment, the sliding block 301 passes through the sliding groove 201 and is fixedly connected to the sliding rod 401 .

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
