Description

Technical Field

[0001] The utility model relates to the technical field of buffer pads, in particular to a polymer material buffer pad with low expansion and contraction. Background Technique

[0002] The buffer pad is usually installed at the rear of the truck to play a buffering role. It can avoid damage to the truck body and the platform when approaching the loading and unloading platform during the unloading process.

[0003] The buffer pad is usually made of rubber, and in order to ensure the buffering effect, the buffer pad is usually a solid structure, resulting in a higher weight of the buffer pad and a greater workload when replacing the buffer pad. Content of the Utility Model

[0004] The purpose of the utility model is to provide a polymer material buffer pad with low expansion and contraction, which can reduce the overall weight of the buffer pad while ensuring the buffering effect of the buffer pad, and reduce the workload when replacing the buffer pad.

[0005] To achieve the above purpose, a polymer material buffer pad with low expansion and contraction is provided, which includes a first buffer block and a second buffer block. One end of the first buffer block is provided with an opening. A nylon net is arranged inside the first buffer block, and the nylon net surrounds the side end of the first buffer block. The second buffer block is fixedly connected to the middle of the first buffer block, and one end of the second buffer block facing the opening extends to the outer end of the first buffer block. A chamber is arranged inside the first buffer block, and one end of the chamber far away from the opening penetrates through the second buffer block. A connecting head is fixedly connected to the middle of the end of the first buffer block far away from the opening, and the connecting head penetrates through the first buffer block. An installation mechanism is fixedly connected to the middle of the end of the first buffer block far away from the opening, and one end of the installation mechanism penetrates through the middle of the connecting head. One end of the installation mechanism is fixedly connected with a spring, and the spring is located in the chamber and fixedly connected with the side wall of the chamber. One end of the middle of the installation mechanism is fixedly connected with a screw rod, and the screw rod is far away from the spring. It can reduce the overall weight of the buffer pad while ensuring the buffering effect of the buffer pad, and reduce the workload when replacing the buffer pad.

[0006] According to the polymer material buffer pad with low expansion and contraction, the installation mechanism is composed of a limiting plate and a threaded column. The threaded column is fixedly connected to the middle of one end of the limiting plate, and the threaded column penetrates through the middle of the connecting head and is threadedly connected with the connecting head. The spring is fixedly connected to the end of the threaded column far away from the limiting plate. The limiting plate is located at the end of the first buffer block far away from the opening. The screw rod is fixedly connected to the middle of the end of the limiting plate far away from the threaded column. It is convenient to disassemble the buffer pad, so as to replace the aged and damaged structure, and reduce the use cost.

[0007] According to the low-expansion and low-shrinkage polymer material buffer pad described above, the inner and outer walls at one end of the first buffer block are coated with a metal shell, and the metal shell is located at the open end of the first buffer block. This is used to reduce the wear when the buffer pad contacts the loading and unloading platform and delay the service life of the buffer pad.

[0008] According to the low-expansion and low-shrinkage polymer material buffer pad described above, the side wall of the second buffer block is a corrugated pipe structure. This reduces the deformation generated outward when the second buffer block is compressed.

[0009] According to the low-expansion and low-shrinkage polymer material buffer pad described above, the first buffer block and the second buffer block are filled with hollow glass microsphere materials. This is used to reduce the expansion coefficient of the buffer pad and reduce the expansion and shrinkage of the buffer pad.

[0010] According to the low-expansion and low-shrinkage polymer material buffer pad described above, an adhesive is provided between the first buffer block and the metal shell, and the first buffer block and the metal shell are in interference fit. This is used to keep the metal shell fixed and prevent the metal shell from falling off when the buffer pad is compressed.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: while ensuring the buffering effect of the buffer pad through the spring, the quality of the buffer pad is reduced, the workload of replacing the buffer pad is reduced, and the nylon net is used to reduce the expansion and shrinkage of the buffer pad caused by temperature influence.

[0020] Please refer to Figures 1-4, the utility model provides a technical solution: a polymer material buffer pad with low expansion and contraction, including a first buffer block 1 and a second buffer block 5. One end of the first buffer block 1 is provided with an opening. The inner and outer walls of one end of the first buffer block 1 are coated with a metal shell 4, and the metal shell 4 is located at the opening end of the first buffer block 1 to reduce the wear when the buffer pad contacts the loading and unloading platform and delay the service life of the buffer pad. There is an adhesive between the first buffer block 1 and the metal shell 4, and the first buffer block 1 and the metal shell 4 are in interference fit to keep the metal shell 4 fixed and prevent the metal shell 4 from falling off when the buffer pad is compressed. A nylon net 6 is arranged in the first buffer block 1, and the nylon net 6 surrounds the side end of the first buffer block 1. The second buffer block 5 is fixedly connected to the middle of the first buffer block 1 and is integrally formed by an injection molding method. One end of the second buffer block 5 facing the opening extends to the outer side end of the first buffer block 1, and the side wall of the second buffer block 5 is a corrugated pipe structure to reduce the deformation generated outward when the second buffer block 5 is compressed. The first buffer block 1 and the second buffer block 5 are filled with hollow glass microsphere materials to reduce the expansion coefficient of the buffer pad and reduce the expansion and contraction of the buffer pad. There is a chamber 9 inside the first buffer block 1, and one end of the chamber 9 far away from the opening penetrates through the second buffer block 5. A connecting head 7 is fixedly connected to the middle of the end of the first buffer block 1 far away from the opening, and the connecting head 7 penetrates through the first buffer block 1. An installation mechanism 2 is fixedly connected to the middle of the end of the first buffer block 1 far away from the opening, and one end of the installation mechanism 2 penetrates through the middle of the connecting head 7. The installation mechanism 2 is composed of a limiting plate 10 and a threaded column 11. The threaded column 11 is fixedly connected to the middle of one end of the limiting plate 10, and the threaded column 11 penetrates through the middle of the connecting head 7 and is threadedly connected to the connecting head 7. A spring 8 is fixedly connected to the end of the threaded column 11 far away from the limiting plate 10.
