Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0022] like Figure 1-4 As shown, the utility model has the following specific embodiments.
[0023] Example:
[0024] A slider with a buffering function comprises a base 1, wherein a slider 2 is movably connected to the top of the base 1, a buffer cavity 21 is provided inside the slider 2, a buffer seat 3 is movably connected to the inside of the buffer cavity 21, support rods 31 are fixedly connected to the four corners of the bottom of the buffer seat 3, a pulley 311 is arranged at one end of the support rod 31 which movably passes through the slider 2, buffer movable arms 4 are rotatably connected to both sides of the buffer cavity 21, one end of the buffer movable arm 4 is rotatably connected to a moving seat 41, a limiting slide bar 32 is fixedly connected to the top of the buffer seat 3, two moving seats 41 are respectively slidably connected to the two ends of the limiting slide bar 32, a spring 42 is fixedly connected between the two moving seats 41, and the spring 42 is sleeved on the limiting slide bar 32.
[0025] By adopting the above technical solution, when using the device, the slider 2 can slide or rise and fall on the base 1 through the limit opening 112 and the slide groove 111, and then the support rod 31 movably connected to the bottom of the slider 2 can slide on the base 1 through the pulley 311, so as to facilitate the movement of the slider 2 on the base 1. At the same time, the buffer seat 3 and the connected buffer movable arm 4 arranged inside the buffer cavity 21 can rotate and cooperate with each other after being compressed, and the spring 42 arranged has a damping effect when it is squeezed by force, so that the slider 2 has a buffering effect after being compressed.
[0026] Specifically, a through hole 11 is formed on the outer surface of the base 1, sliding grooves 111 are formed on both sides of the through hole 11, and a limiting opening 112 is formed on the top of the through hole 11;
[0027] The slider 2 slides with the base 1 in a limited position through the slide groove 111 , and the slider 2 extends from the top of the base 1 through the limited opening 112 .
[0028] By adopting the above technical solution, the provided limiting opening 112 can enable the slider 2 to be movably fitted with the base 1 , and at the same time, the sliding groove 111 provided inside the through hole 11 can limit the movement of the slider 2 .
[0029] Specifically, two limiting grooves 12 parallel to each other are formed at the bottom of the through hole 11 , and guide rails 121 are provided inside the limiting grooves 12 , and the pulley 311 rolls on the guide rails 121 .
[0030] An angle is set between the buffer movable arm 4 and the buffer seat 3. When the buffer seat 3 is attached to the bottom of the buffer cavity 21, the angle between the buffer movable arm 4 and the buffer seat 3 is the largest. When the buffer seat 3 gradually rises, the angle between the buffer movable arm 4 and the buffer seat 3 gradually decreases.
[0031] By adopting the above technical scheme, when the slider 2 is squeezed by the downward force, the slider 2 pushes the moving seat 41 through the rotating connected buffer movable arm 4, the moving seat 41 squeezes the limiting slide bar 32, the limiting slide bar 32 squeezes the buffer seat 3, and the buffer seat 3 squeezes the pulley 311 through the support rod 31, so that the pulley 311 can roll on the guide rail 121 inside the limiting groove 12, and since the moving seat 41 connected by the rotating buffer movable arm 4 can slide on the limiting slide bar 32, the spring 42 mounted on the limiting slide bar 32 has a damping effect after being subjected to force, so that when the slider 2 is subjected to force and extrusion, the buffer seat 3 connected to the buffer movable arm 4 can rise and fall inside the buffer cavity 21, so that the slider 2 can have a buffering effect when it is squeezed under force.
