DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figure 1-5The utility model provides a sealing ring with a buffer structure, comprising a support ring 1, a buffer rubber pad 101, a first shock-absorbing ring 102, a telescopic groove 103, a first clamping groove 104, a second shock-absorbing ring 2, a telescopic column 201, a second clamping groove 202, a sealing layer 3, a buffer layer 4, a round hole 401, a spring 402, an outer rubber ring 5, and an inner rubber ring 6. The second shock-absorbing ring 2 is arranged at the upper and lower ends of the support ring 1. The support ring 1 is divided into two upper and lower structures with the same thickness, and a buffer rubber pad 101 is fixed between the upper and lower structures of the support ring 1. The buffer rubber pad 101 arranged in the support ring 1 can buffer the vibration. Two groups of first shock-absorbing rings 102 of annular structures are fixed on one side of the support ring 1 close to the second shock-absorbing ring 2. The two groups of first shock-absorbing rings 102 are divided into an inner ring first shock-absorbing ring 102 and an outer ring first shock-absorbing ring 102, and the minimum diameter size of the inner ring first shock-absorbing ring 102 is consistent with the minimum diameter size of the second shock-absorbing ring 2, and And the maximum diameter size of the outer ring first shock-absorbing ring 102 is consistent with the maximum diameter size of the second shock-absorbing ring 2. A first groove 104 is arranged between the inner ring first shock-absorbing ring 102 and the outer ring first shock-absorbing ring 102 of the first shock-absorbing ring 102, and the buffer layer 4 is connected to the support ring 1 through the first groove 104. The buffer layer 4 arranged in the first shock-absorbing ring 102 can play a buffering role by compressing the buffer layer 4 when the second shock-absorbing ring 2 and the support ring 1 are squeezed, and the setting of the first shock-absorbing ring 102 and the second shock-absorbing ring 2 can fix the position of the buffer layer 4. A second groove 202 is opened on the surface of the second shock-absorbing ring 2 close to the support ring 1, and the buffer layer 4 is connected to the second shock-absorbing ring 2 through the second groove 202. Through the second groove 202 and the first groove 104 in the second shock-absorbing ring 2 and the first shock-absorbing ring 102, the buffer layer 4 between the second shock-absorbing ring 2 and the support ring 1 can be fixed and limited.

[0027] A plurality of cylindrical telescopic columns 201 are fixed to a side of the second damping ring 2 close to the first damping ring 102, and the telescopic columns 201 of the second damping ring 2 are divided into an inner circle and an outer circle, and the distribution of the inner circle and outer circle of the telescopic columns 201 of the second damping ring 2 is consistent with the distribution of the inner and outer circles of the first damping ring 102. The telescopic columns 201 on the second damping ring 2 can pass through the telescopic groove 103 of the first damping ring 102, so that the second damping ring 2 and the first damping ring 102 can slide. When the telescopic column 201 is in motion, the telescopic direction can be limited by the telescopic column 201, and then the inner buffer layer 4 and the spring 402 are used for buffering. A telescopic groove 103 is provided at the connection between the telescopic column 201 and the first shock-absorbing ring 102, and the telescopic groove 103 is provided on the first shock-absorbing ring 102, and the telescopic column 201 is slidably connected to the telescopic groove 103. The telescopic groove 103 allows the telescopic column 201 to slide inside, thereby making the sliding between the second shock-absorbing ring 2 and the first shock-absorbing ring 102 more stable.

[0028] The second shock-absorbing ring 2 is distributed in a mirror image with the support ring 1 as the axis. The two groups of second shock-absorbing rings 2 are covered with a sealing layer 3 on one side away from the support ring 1. The two groups of second shock-absorbing rings 2 are inlaid with a buffer layer 4 on one side close to the support ring 1. The buffer layer 4 is made of polyethylene foam plastic material, and the thickness of the buffer layer 4 is greater than the sum of the depth dimensions of the first card slot 104 and the second card slot 202. The polyethylene foam plastic material of the buffer layer 4 can better play a buffering and shock-absorbing effect, and can allow the buffer layer 4 to have enough space to be squeezed. Eight groups of circular holes 401 are opened on the buffer layer 4, and springs 402 are arranged inside the eight groups of circular holes 401, and the length of the spring 402 is greater than Regarding the thickness of the buffer layer 4, by arranging a distributed spring 402 inside the buffer layer 4, the buffering effect of the buffer layer 4 can be improved. An outer rubber ring 5 and an inner rubber ring 6 are arranged on the side of the second shock-absorbing ring 2 close to the sealing layer 3. The outer rubber ring 5 and the inner rubber ring 6 are both arranged as annular structures, and the inner rubber ring 6 and the outer rubber ring 5 are hollow inside, and the top surface and the ground of the outer rubber ring 5 and the inner rubber ring 6 are fixedly connected to the sealing layer 3 and the support ring 1. The outer rubber ring 5 and the inner rubber ring 6 can connect the sealing layer 3 and the support ring 1, so that the outer side of the device remains in a completely sealed state, thereby achieving a buffering effect through the internal buffer layer 4 while also allowing the device to maintain a good sealing effect.

[0029] When the embodiment of the present application is in use: by placing the device in the position of use, when it receives impact and pressure during use, the sealing layers 3 on the upper and lower sides of the support ring 1 can follow the pressure to move closer to the support ring 1. During this process, the second shock-absorbing ring 2 in the sealing layer 3 can slide inside the telescopic groove 103 of the first shock-absorbing ring 102 through the telescopic column 201. At the same time, the distance between the first shock-absorbing ring 102 and the second shock-absorbing ring 2 will become smaller, thereby reducing the internal space height of the first card slot 104 and the second card slot 202, so that the buffer layer 4 arranged inside will be squeezed, and the polyethylene foam plastic material of the buffer layer 4 can better play a role in buffering and shock absorption, and springs 402 are distributed inside the buffer layer 4 to buffer the movement of the second shock-absorbing ring 2, so that the internal buffer layer 4 and the spring 402 can make the device sealed and have a buffering effect at the same time;

[0030] The outer rubber ring 5 and the inner rubber ring 6 arranged between the sealing layer 3 and the support ring 1 can keep the sealing layer 3 and the support ring 1 connected and sealed, and ensure the integrity of the device surface when the second shock-absorbing ring 2 and the sealing layer 3 move, so that the device has a buffering effect and a sealing function at the same time. In this way, a sealing ring with a buffering structure is ready for use. It should be noted that the utility model is a sealing ring with a buffering structure.
