Description

Technical Field

[0001] The utility model relates to the technical field of relays, and particularly relates to a relay with an anti-vibration structure. Background Art

[0002] According to the "relay with an anti-vibration structure" proposed in the application number: "202120948650.4", when the relay body vibrates in a complex environment, the vibration causes the mounting seat to vibrate, resulting in the deformation of the elastic support frame, thereby absorbing part of the vibration. Then, the vibration causes the support to vibrate, squeezing the sliding plate to slide vertically in the sliding frame, squeezing the support spring to deform, thereby absorbing part of the vibration. The vibration causes the support to rotate in the rotating cylinder of the support column, squeezing the return spring to deform and absorbing the vibration to ensure horizontal. Thus, the relay can be supported under complex working conditions, reducing the impact of vibration on the relay and ensuring the service life of the relay. Thereby, it overcomes the problem that the existing relay does not have an anti-vibration structure, resulting in a low service life of the existing relay under the interference of vibration force.

[0003] The inventor found the following problems in the prior art that were not well solved during the implementation of this solution: It uses a return spring and a support spring for vibration reduction, and achieves the limit buffer movement for vibration reduction through the sliding of the sliding plate in the sliding frame. Due to the large number and length of the springs, when vibration occurs, although the springs can reduce the damage caused by vibration to the relay, the large amount of back vibration of the springs will cause the relay to be in a state of up and down vibration for a long time and unable to be in a stable state, thus having a greater impact on the operation of the relay. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a relay with an anti-vibration structure, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A relay with an anti-vibration structure includes a relay. Positioning cylinders are fixed at the four corners of the relay. An upper circular thread groove is drilled in the inner top of the positioning cylinder. A lower circular groove is drilled at the inner bottom of the positioning cylinder where the upper circular thread groove is located. A damping ring is arranged at the inner bottom of the upper circular thread groove. A gasket is arranged above the damping ring. Bolts are inserted into the interiors of the positioning cylinders. Cap nuts are arranged at the tops of the positioning cylinders. A first damping pad is adhesively bonded to the bottom of each cap nut. An external thread column is fixed to the bottom of the relay. An internal thread tube is threadedly connected to the outer wall of the external thread column. A second damping pad is adhesively bonded to the bottom of the internal thread tube. A number of damping balls are arranged at the bottom of the second damping pad.

[0007] Preferably, the bolt is divided into a bolt head and a bolt rod. The bolt head of the bolt is located inside the upper circular thread groove. The bolt rod of the bolt penetrates through and communicates with the gasket, the shock-absorbing ring, and the lower circular groove. The bottom of the gasket is in contact with the top of the shock-absorbing ring, and the bottom of the bolt head of the bolt is in contact with the top of the gasket.

[0008] Preferably, the outer diameter of the bolt rod of the bolt is smaller than the inner diameter of the upper circular thread groove.

[0009] Preferably, the bottom of the first shock-absorbing pad is in contact with the top of the bolt.

[0010] Preferably, the outer wall of the bottom of the barrel cap is provided with screw teeth, the inner wall of the upper circular thread groove is provided with internal threads, and the screw teeth of the barrel cap are threadedly connected with the internal threads of the upper circular thread groove.

[0011] Preferably, the shock-absorbing balls are all hollow balls.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When vibration occurs, the vibration force will be conducted to the position of the positioning cylinder through the bolt. The bolt presses the gasket, and the gasket is in contact with the shock-absorbing ring. The vibration force will be transmitted to the shock-absorbing ring through the bolt and the gasket. The shock-absorbing ring can have a good shock-absorbing effect on the vibration force. The threaded connection between the barrel cap and the positioning cylinder can make the bottom of the first shock-absorbing pad press tightly on the top of the bolt, not only ensuring the stability of the connection between the positioning cylinder and the bolt, but also being able to play a certain role in reducing the vibration force.

[0014] 2. The external thread column is threadedly connected with the internal thread pipe. When the internal thread pipe rotates, it can drive the shock-absorbing balls at the bottom of the second shock-absorbing pad to be in contact with the mounting plate, increasing the stability of the relay after installation. And when vibration occurs, the second shock-absorbing pad and several shock-absorbing balls can further reduce the vibration force, making the relay have a better anti-vibration effect during operation.

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, a relay with an anti-vibration structure includes a relay 1. Positioning cylinders 2 are fixed at the four corners of the relay 1. An upper circular screw groove 21 is drilled in the inner top of the positioning cylinder 2. A lower circular groove 22 is drilled in the inner bottom of the positioning cylinder 2 located in the upper circular screw groove 21. A vibration damping ring 23 is provided at the inner bottom of the upper circular screw groove 21. A gasket 24 is provided above the vibration damping ring 23. Bolts 4 are inserted into the interiors of the positioning cylinders 2. Cylinder caps 3 are provided at the tops of the positioning cylinders 2. First vibration damping pads 31 are adhesively bonded to the bottoms of the cylinder caps 3. An external thread column 5 is fixed to the bottom of the relay 1. An internal thread pipe 6 is threadedly connected to the outer wall of the external thread column 5. A second vibration damping pad 7 is adhesively bonded to the bottom of the internal thread pipe 6. A plurality of vibration damping balls 8 are provided at the bottom of the second vibration damping pad 7.

[0022] Specifically, the bolt 4 is divided into a bolt head and a bolt rod. The bolt head of the bolt 4 is located inside the upper circular screw groove 21. The bolt rod of the bolt 4 penetrates and communicates with the gasket 24, the vibration damping ring 23 and the lower circular groove 22. The bottom of the gasket 24 is in contact with the top of the vibration damping ring 23. The bottom of the bolt head of the bolt 4 is in contact with the top of the gasket 24.

[0023] Specifically, the outer diameter dimension of the bolt rod of the bolt 4 is smaller than the inner diameter dimension of the upper circular screw groove 21, so as to prevent the vibration force from being transmitted to the relay 1 through the contact between the bolt rod and the inner wall of the upper circular screw groove 21.

[0024] Specifically, the bottom of the first vibration damping pad 31 is in contact with the top of the bolt 4. The outer wall of the bottom of the cylinder cap 3 is provided with screw teeth. The inner wall of the upper circular screw groove 21 is provided with internal threads. The screw teeth of the cylinder cap 3 are threadedly connected with the internal threads of the upper circular screw groove 21, so that the first vibration damping pad 31 can abut against the top of the bolt 4, thereby achieving a limit-type anti-vibration effect.

[0025] Specifically, the vibration damping balls 8 are all hollow balls, which can absorb energy through deformation to achieve a better vibration damping effect.

[0026] Working principle: When vibration occurs, the vibration force is conducted to the position of the positioning cylinder 2 through the bolt 4. The bolt 4 presses the gasket 24, and the gasket 24 is in contact with the damping ring 23. The vibration force is transmitted to the damping ring 23 through the bolt 4 and the gasket 24. The damping ring 23 can achieve a good damping effect on the vibration force. The threaded connection between the barrel cap 3 and the positioning cylinder 2 can make the bottom of the first damping pad 31 press tightly on the top of the bolt 4, which not only ensures the stability of the connection between the positioning cylinder 2 and the bolt 4, but also can play a certain role in reducing the vibration force. The external threaded column 5 is threadedly connected with the internal threaded tube 6. When the internal threaded tube 6 rotates, it can drive the damping balls 8 at the bottom of the second damping pad 7 to be in contact with the mounting plate, increasing the stability of the relay 1 after installation. And when vibration occurs, the second damping pad 7 and several damping balls 8 can further reduce the vibration force, making the relay 1 have a better anti-vibration effect during operation.
