[0015] Beneficial effects
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] This pull-out cabinet anti-pinch damper uses a connecting plate and a buffer plate, with springs acting as a buffer to provide cushioning and protection. The connecting end uses an elastic bend to connect to the buffer cavity, securing the damper. Magnetic plates hold the elastic bends together, fixing them within the buffer cavity. A first buffer spring within the buffer cavity applies impact force to one end of the cabinet when it is pulled out, preventing pinching. A connecting rod connects to one end of a movable rod, allowing the damper to be installed between the pull-out cabinet sections. A movable frame limits the connection between the connecting rod and the movable rod. A limit plate and an adjusting plate, with an adjusting arm, limit the connection between the damper and the connecting rod. Simultaneously, the limit rod moves with the cabinet within the buffer block, contacting a second buffer spring, allowing the cabinet to spring back when impacted, preventing pinching and providing protection.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1-4 As shown, a pull-out cabinet anti-pinch buffer damper includes a pull-out cabinet 1 and a storage cabinet 2, with a buffer mounting component 3 provided at one end of the storage cabinet 2.
[0025] The buffer installation assembly 3 includes a connecting plate 301 disposed at one end of the storage cabinet 2 near the pull-out cabinet 1. The end of the connecting plate 301 away from the storage cabinet 2 is connected to a buffer cavity 304. Both ends of the buffer cavity 304 are connected to multiple first buffer springs 309. The end of the buffer cavity 304 away from the first buffer springs 309 is connected to an elastic bend 305. One end of the elastic bend 305 is connected to a magnetic absorbing piece 308. The outer wall of the elastic bend 305 away from the buffer cavity 304 is connected to a connecting end 306. The end of the connecting end 306 away from the elastic bend 305 is connected to a damper 307. The end of the damper 307 away from the connecting end 306 is connected to a connecting rod 310. The end of the connecting rod 310 away from the damper 307 is connected to a connecting rod 317. The end of the connecting rod 317 away from the connecting rod 310 is connected to a buffer block 318.
[0026] One end of the linkage rod 310 is connected to a movable rod 311. The end of the movable rod 311 away from the linkage rod 310 is connected to a movable frame 312. The ends of the movable frame 312 away from the movable rod 311 are connected to a limit plate 313 by fastening bolts. The ends of the limit plate 313 away from the movable frame 312 are connected to an adjusting arm 314 by fastening bolts. The ends of the adjusting arm 314 away from the limit plate 313 are connected to an adjusting plate 315. The sides of the two adjusting plates 315 away from the adjusting arm 314 are connected to a limit rod 316. Both ends of the buffer block 318 are connected to multiple second buffer springs 319. The end of the buffer block 318 away from the linkage rod 310 is connected to a buffer plate 303. The ends of the connecting plate 301 and the buffer plate 303 near the damper 307 are connected to springs 302.
[0027] The flexible bend 305 is attracted to each other by two magnetic plates 308. The end of the flexible bend 305 away from the connecting end 306 is in contact with multiple first buffer springs 309 arranged inside the buffer cavity 304. The movable rod 311 passes through one end of the connecting rod 310 and is threadedly fixed to the movable frame 312. The movable frame 312 is connected to the limiting plate 313 by fastening bolts. The limiting plate 313 is movably connected to the adjusting plate 315 by the adjusting arm 314. The two adjusting plates 315 pass through the interior of the buffer block 318 and are connected to the limiting rod 316. The connecting rod 310 is movably connected to the connecting rod 317; the connecting rod 317 is rotatably connected to the buffer block 318; the buffer block 318 is threadedly fixedly connected to the buffer plate 303; both the connecting plate 301 and the buffer plate 303 are movably connected to the spring 302; the outer wall of the limiting rod 316 contacts the multiple second buffer springs 319 inside the buffer block 318; the side of the adjusting plate 315 near the buffer block 318 contacts it; and the side of the buffer block 318 near the connecting rod 317 contacts the side of the movable frame 312.
[0028] In this process, the two magnetic plates 308 of the elastic bend 305 are attracted to each other and fixed in the buffer cavity 304. The first buffer spring 309 is placed in the buffer cavity 304. The end of the elastic bend 305 away from the connecting end 306 is brought into contact with the first buffer spring 309. The connecting end 306 is connected to the elastic bend 305. The damper 307 is connected to the elastic bend 305 through the connecting end 306. The movable rod 311 passes through one end of the connecting rod 310 and is fixedly connected to the movable frame 312 by threads. The movable frame 312 is then tightened. Bolts are connected to the limiting plate 313, and the limiting plate 313 is movably connected to the adjusting plate 315 through the adjusting arm 314. The two adjusting plates 315 pass through the interior of the buffer block 318 and are threadedly fixed to the limiting rod 316. The assembled buffer installation assembly 3 is installed between the pull-out cabinet 1 and the storage cabinet 2, ensuring that the connecting plate 301 and the buffer plate 303 are firmly connected to the pull-out cabinet 1 and the storage cabinet 2 respectively. The damping force of the damper 307 and the position of the adjusting plate 315 and the limiting rod 316 are adjusted as needed to achieve the best buffering and protection effect.
[0029] It should be noted that this utility model is a pull-out cabinet anti-pinch buffer damper. When in use, when the user pushes the pull-out cabinet 1 back, the storage cabinet 2 begins to move inward. As the storage cabinet 2 moves inward, the first buffer spring 309 begins to release elastic potential energy, generating a rebound force to offset part of the impact force when closing. The damper 307 continues to work, providing resistance and controlling the closing speed of the pull-out cabinet 1 to prevent the hand from being pinched due to excessively fast closing. When the storage cabinet 2 is close to being completely closed, the second buffer spring 319 inside the buffer block 318 is further compressed to absorb the impact force when closing. Meanwhile, due to the elastic potential energy of the second buffer spring 319, at the instant the storage cabinet 2 is fully closed, the second buffer spring 319 quickly rebounds, pushing the limit rod 316 and the buffer block 318, causing the storage cabinet 2 to produce a slight rebound action, avoiding pinching the hand. During the closing process, the connecting plate 301 and the buffer plate 303 further absorb the impact force through the elastic deformation of the spring 302, playing a buffering role. This damper provides multi-level protection during the pulling and closing process through the three-stage buffer design of the first buffer spring 309, the second buffer spring 319 and the spring 302. The damper 307 provides adjustable damping force, which can control the moving speed of the pull-out cabinet 1 as needed. The rebound action of the second buffer spring 319 effectively avoids the risk of pinching the hand when the pull-out cabinet 1 is fully closed. The magnetic fixation of the elastic bend 305, the limiting connection of the linkage rod 310 and the movable rod 311, and the threaded fixation of the adjusting plate 315 and the limit rod 316 ensure the stability and reliability of the entire buffer installation assembly 3.
