Description

Technical Field

[0001] This utility model relates to the field of insertion device technology, specifically a single-leaf rotary hyperboloid wire spring insertion device. Background Technology

[0002] The single-leaf rotary hyperboloid spring socket is a highly reliable socket assembly used in electrical connectors and plug-in products.

[0003] In practical use, most existing single-leaf rotary hyperboloid wire spring sockets use rigid guides to insert the pins. However, after prolonged use, the rigid guides may wear down, resulting in poor guiding performance. In addition, the wire springs are located inside the device and wound around the outside of the coil, making replacement extremely time-consuming and difficult. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a single-leaf rotary hyperboloid wire spring insertion part, which has the advantages of reduced pin guiding friction and easy replacement of the wire spring, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a single-leaf rotary hyperboloid wire spring insert, comprising a fixed shell, a pin inside the fixed shell, a threaded base threaded to the inner wall of the fixed shell, a connecting strip fixedly installed on the top of the threaded base, a fixed top ring fixedly installed on the top of the connecting strip, a wire spring wire slidably connected to the inner wall of the threaded base, a sliding block slidably connected to the inner wall of the connecting strip, a movable groove on the outer wall of the connecting strip, a pull rod slidably connected to the inner wall of the sliding block, a connecting frame fixedly installed on the outer wall of the pull rod, an elastic rubber strip fixedly installed on the outer wall of the connecting frame, a second spring on the inner wall of the sliding block, a fixed groove on the outer wall of the wire spring wire, a deep groove on the top of the fixed top ring, a bolt slidably connected to the inner wall of the deep groove, an inner extension block fixedly installed to the inner wall of the fixed shell, an oil storage pipe slidably connected to the inner wall of the inner extension block, a sliding ball rotatably connected to the inner wall of the oil storage pipe, a sealing cap slidably connected to the inner wall of the oil storage pipe, and a first spring on the inner wall of the inner extension block.

[0006] As a preferred technical solution of this utility model: the inner wall shape of the fixing groove is adapted to the shape of the elastic rubber strip, and the elastic rubber strip is located on the inner wall of the fixing groove.

[0007] As a preferred technical solution of this utility model: the bolt penetrates the bottom of the inner wall of the fixed top ring and extends to the inner wall of the sliding block, and the bolt and the sliding block are connected by threads.

[0008] As a preferred technical solution of this utility model: the diameter of the sliding ball is the same as the diameter of the side of the oil storage tube near the sliding ball, and the side of the oil storage tube near the sliding ball is penetrated.

[0009] As a preferred technical solution of this utility model: the inner wall diameter of the fixed top ring is adapted to the diameter of the oil storage pipe, and the inner wall diameter of the spring near the sliding ball is smaller than the diameter of the sliding ball.

[0010] As a preferred technical solution of this utility model: the pull rod passes through the sliding block, and the pull rod and the sliding block are in contact at the through point, and the end of the pull rod that passes through the sliding block is located inside the movable groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This single-leaf rotary hyperboloid spring insert component, through the downward movement of the insert pin, drives the sliding ball to rotate, thereby causing the sliding ball to carry out the lubricating oil inside the oil reservoir. The rotation of the sliding ball rotates the lubricating oil to the side close to the insert pin, thereby reducing the friction coefficient between the sliding ball and the insert pin and thus protecting it. When the insert pin shakes on the inner wall of the fixed shell, the sliding ball is squeezed, causing the sliding ball to drive the oil reservoir to move inside the inner extension block. The movement of the oil reservoir compresses the spring, and the spring rebounds to reset the structure, thereby pushing the insert pin back and guiding it.

[0012] 2. This single-leaf rotary hyperboloid wire spring insert can be made to disengage from the sliding block by rotating the bolt, allowing the sliding block to move downwards. At this time, pressing the pull rod causes the pull rod to move the connecting frame, which in turn causes the connecting frame to move the elastic rubber strip. At this time, the elastic rubber strip separates from the inner wall of the fixing groove, thus eliminating the fixing relationship of the wire spring. The wire spring can then be pulled out from the bottom and replaced. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 6 A single-leaf hyperboloidal wire spring insert includes a fixed housing 1, with a pin 2 inside the fixed housing 1. A threaded base 3 is threadedly connected to the inner wall of the fixed housing 1. A connecting strip 5 is fixedly installed on the top of the threaded base 3, and a fixed top ring 4 is fixedly installed on the top of the connecting strip 5. A wire spring wire 6 is slidably connected to the inner wall of the threaded base 3. A sliding block 7 is slidably connected to the inner wall of the connecting strip 5. A movable groove 20 is provided on the outer wall of the connecting strip 5. A pull rod 8 is slidably connected to the inner wall of the sliding block 7. A connecting frame 9 is fixedly installed on the outer wall of the pull rod 8. An elastic rubber strip 10 is fixedly installed on the outer wall of the sliding block 7. A second spring 19 is provided on the inner wall of the sliding block 7. A fixing groove 11 is opened on the outer wall of the wire spring 6. A deep groove 12 is opened on the top of the fixed top ring 4. A bolt 13 is slidably connected to the inner wall of the deep groove 12. An inner extension block 14 is fixedly installed on the inner wall of the fixed shell 1. An oil storage pipe 16 is slidably connected to the inner wall of the inner extension block 14. A sliding ball 15 is rotatably connected to the inner wall of the oil storage pipe 16. A sealing cap 17 is slidably connected to the inner wall of the oil storage pipe 16. A first spring 18 is provided on the inner wall of the inner extension block 14.

[0017] In the above structure, by rotating the threaded base 3, the threaded base 3 moves downward through the threaded connection with the fixed shell 1, thereby removing the threaded base 3 from the inner wall of the fixed shell 1. At this time, the threaded base 3 continues to move downward, thereby causing the threaded base 3 to drive the connecting strip 5 and the fixed top ring 4 to move downward, so that the threaded base 3, the fixed top ring 4 and the connecting strip 5 are removed from the inner wall of the fixed shell 1.

[0018] In a preferred embodiment, the inner wall of the fixing groove 11 is adapted to the shape of the elastic rubber strip 10, and the elastic rubber strip 10 is located on the inner wall of the fixing groove 11.

[0019] In the above structure, the spring 19 pulls the connecting frame 9 back, which in turn causes the connecting frame 9 to move the elastic rubber strip 10, causing the elastic rubber strip 10 to move towards the inner wall of the fixing groove 11, and thus the elastic rubber strip 10 enters the inner wall of the fixing groove 11, so that both sides of the fixing groove 11 are fixed by the elastic rubber strip 10 and the inner wall of the connecting strip 5, thereby fixing the position of the elastic rubber strip 10.

[0020] In a preferred embodiment: the bolt 13 penetrates the bottom of the inner wall of the fixed top ring 4 and extends to the inner wall of the sliding block 7, and the bolt 13 and the sliding block 7 are threadedly connected.

[0021] In the above structure, by inserting the bolt 13 into the inner wall of the groove 12, the bottom of the bolt 13 reaches the interior of the sliding block 7. At this time, by rotating the bolt 13, the bolt 13 moves into the interior of the sliding block 7 through the threaded connection with the sliding block 7, thereby fixing the position of the sliding block 7.

[0022] In a preferred embodiment: the diameter of the sliding ball 15 is the same as the diameter of the side of the oil reservoir 16 near the sliding ball 15, and the side of the oil reservoir 16 near the sliding ball 15 is penetrated.

[0023] In the above structure, the rotation of the sliding ball 15 causes the lubricating oil inside the oil storage pipe 16 to be carried by the outer surface of the sliding ball 15, thereby delivering the lubricating oil to the outside through the rotation of the sliding ball 15, while the sliding ball 15 seals the oil storage pipe 16.

[0024] In a preferred embodiment: the inner diameter of the fixed top ring 4 is adapted to the diameter of the oil reservoir 16, and the inner diameter of the spring 18 on the side near the sliding ball 15 is smaller than the diameter of the sliding ball 15.

[0025] In the above structure, the sliding ball 15 is limited by the inner wall of the fixed top ring 4 on the side close to the sliding ball 15, so that the sliding ball 15 cannot be separated from the inner wall of the fixed top ring 4, and thus the oil storage pipe 16 cannot be separated from the inner wall of the fixed top ring 4. At the same time, the fit between the oil storage pipe 16 and the inner wall of the fixed top ring 4 ensures that the oil storage pipe 16 will not deviate when moving.

[0026] In a preferred embodiment: the pull rod 8 passes through the sliding block 7, and the pull rod 8 and the sliding block 7 are in contact at the through point, with one end of the pull rod 8 passing through the sliding block 7 located inside the movable groove 20.

[0027] In the above structure, the pull rod 8 is limited by the contact between the pull rod 8 and the sliding block 7, so that the pull rod 8 will not tilt during the movement. At the same time, the extension and retraction of the pull rod 8 can be operated inside the movable groove 20.

[0028] Working Principle: When using this equipment, the pin 2 is inserted into the interior of the fixed housing 1. Upon entering the housing, the outer wall of the pin 2 contacts the outer wall of the sliding ball 15. The downward movement of the pin 2 causes the sliding ball 15 to rotate, thus carrying the lubricating oil from the oil reservoir 16 outwards. The rotation of the sliding ball 15 moves the lubricating oil to the outside, reducing the friction coefficient between the sliding ball 15 and the pin 2, thus protecting them. When the pin 2 vibrates against the inner wall of the fixed housing 1, it squeezes the sliding ball 15, causing the oil reservoir 16 to move. The oil reservoir 16 compresses the spring 18. The spring 18 then rebounds, resetting the structure and pushing the pin 2 back, guiding it. When the wire 6 needs to be aligned... When replacing, rotate the threaded base 3, causing it to move downwards through the threaded connection with the fixed housing 1, thus removing the threaded base 3 from the inner wall of the fixed housing 1. Continue moving the threaded base 3 downwards, causing it to move the connecting strip 5 and the fixed top ring 4 downwards, thus removing the threaded base 3, the fixed top ring 4, and the connecting strip 5 from the inner wall of the fixed housing 1. Then, rotate the bolt 13, causing it to disengage from the sliding block 7, allowing the sliding block 7 to move downwards. Press the pull rod 8, causing it to move the connecting frame 9, which in turn moves the elastic rubber strip 10. At this point, the elastic rubber strip 10 separates from the inner wall of the fixing groove 11, thus eliminating the fixing relationship of the spring wire 6. The spring wire 6 can then be pulled out from the bottom and replaced.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
