Description

Technical Field

[0001] This utility model relates to the field of fishing rod manufacturing technology, specifically to an elastic positioning pin. Background Technology

[0002] Elastic locating pins, also known as spring pins, are headless, hollow cylindrical bodies with axial slots and chamfered ends. They are used for positioning, connecting, and fixing parts. The elastic material of the elastic locating pin can absorb external vibration and impact, reduce wear on connected parts, and extend equipment life. They are especially suitable for applications with vibration.

[0003] While existing flexible locating pins can reduce wear on connecting parts and extend equipment life, it has been found that the initial outer diameter of the flexible locating pin must be larger than the inner diameter of the connecting part's pin groove to allow it to adhere tightly to the inner wall of the groove and reduce wear. This necessitates the use of tools to tap the flexible locating pin during disassembly and assembly, making it prone to deformation or damage. Existing flexible locating pins are inconvenient to disassemble and use. Therefore, we propose a new type of flexible locating pin to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an elastic positioning pin to solve the problems currently existing in the market as described in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elastic positioning pin, comprising a pin body, wherein a first baffle is fixedly connected to the outer side of the pin body near the top, and a second baffle is fixedly connected to the top of the pin body, wherein...

[0006] A notch is provided on one side of the pin body, and a top plate is provided at the end of the pin body corresponding to the second baffle. A sliding groove is symmetrically provided on the side of the top plate near the second baffle. A slider is provided in the sliding groove, and a lead screw is rotatably connected in the sliding groove.

[0007] The lead screw is fixedly connected to a hexagonal head at one end outside the top plate, and the slider is fixedly connected to a sliding seat on the side away from the top plate. The pin is symmetrically provided with clamping plates on the outer side between the first baffle and the second baffle, and the clamping plates are fixedly connected to the sliding seat through a support rod.

[0008] Preferably, the first baffle and the second baffle are both fixedly connected to the pin by welding, and the outer diameter of the first baffle and the second baffle is larger than the outer diameter of the pin.

[0009] Preferably, both the groove and the slider are T-shaped, and the internal dimensions of the groove match the external dimensions of the slider.

[0010] Preferably, the lead screw is provided with two opposite external threads, and the lead screw is threadedly connected to the sliders on both sides through the two opposite external threads.

[0011] Preferably, the clamping plate is an arc-shaped plate, and the inner diameter of the clamping plate matches the outer diameter of the pin.

[0012] Preferably, the support rod is fixedly connected to the sliding seat by bolt installation.

[0013] Preferably, the clamping plate has symmetrical guide rod grooves on the upper and lower sides near the support rod, and the pin is fixedly connected to the guide rod groove on the outer side.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, when it is necessary to insert or remove the pin, uses a wrench to rotate the hexagonal head, which in turn rotates the lead screw. The lead screw causes the two side sliders to move closer together, which in turn causes the two side clamps to move closer together, compressing the pin and causing it to be compressed through the notch. This reduces the outer diameter of the pin to be smaller than the inner diameter of the pin groove, allowing it to be easily inserted into or removed from the connector pin groove. After insertion, rotating the lead screw in the opposite direction releases the pin's own elasticity, causing the outer wall of the pin to fit tightly against the inner wall of the connector pin groove. The elastic material itself can absorb external vibration and impact, reducing wear on the connecting parts. At the same time, this positioning pin structure can reduce the outer diameter of the pin during disassembly and assembly, making it easier to disassemble and assemble the pin and preventing damage to the pin during disassembly and assembly.

[0016] This invention allows the screw to rotate via a hexagonal head, which can be connected to a wrench. This leverage principle saves the force required to rotate the screw. When the screw rotates, the two opposite external threads can move the two side clamps closer or further apart, thus facilitating the clamping or releasing of the pin.

[0017] In this invention, when the clamping plate moves, the guide structure formed by the guide rod groove and the guide rod can guide the movement of the clamping plate, and at the same time limit the clamping position of the clamping plate on the pin body, so that the notch direction of the pin body is located between the two clamping plates, thereby ensuring that when the clamping plates approach each other, the outer diameter of the pin body can be reduced through the notch.

[0023] 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.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: an elastic positioning pin, including a pin body 1, a first baffle 2 fixedly connected to the outer side of the pin body 1 near the top, and a second baffle 3 fixedly connected to the top of the pin body 1, wherein...

[0025] A notch 4 is provided on one side of the pin body 1. A top plate 5 is provided at the end of the pin body 1 corresponding to the second baffle 3. A sliding groove 6 is symmetrically provided on the side of the top plate 5 near the second baffle 3. A slider 7 is provided in the sliding groove 6. A lead screw 8 is rotatably connected in the sliding groove 6.

[0026] A hexagonal head 9 is fixedly connected to one end of the lead screw 8 outside the top plate 5. A sliding seat 10 is fixedly connected to the side of the slider 7 away from the top plate 5. A clamping plate 11 is symmetrically arranged on the outer side of the pin body 1 between the first baffle 2 and the second baffle 3. The clamping plate 11 is fixedly connected to the sliding seat 10 through the support rod 12.

[0027] When it is necessary to insert or remove the pin 1, the wrench drives the hexagonal head 9 to rotate, which in turn drives the lead screw 8 to rotate. The lead screw 8 drives the two side sliders 7 to move closer together, which in turn drives the two side clamps 11 to move closer together, squeezing the pin 1 and compressing it through the notch 4. This reduces the outer diameter of the pin 1 to be smaller than the inner diameter of the pin groove, allowing it to be easily inserted into or removed from the pin groove of the connector. After insertion, rotating the lead screw 8 in the opposite direction releases the elasticity of the pin 1, causing the outer wall of the pin 1 to fit tightly against the inner wall of the pin groove of the connector. The elastic material itself can absorb external vibration and impact, reducing wear on the connecting parts. At the same time, through this positioning pin structure, the outer diameter of the pin 1 can be reduced during disassembly and assembly, making it easier to disassemble and assemble the pin 1 and preventing damage to the pin 1 during disassembly and assembly.

[0028] Please see Figures 1 to 4The first baffle 2 and the second baffle 3 are fixedly connected to the pin 1 by welding, and the outer diameter of the first baffle 2 and the second baffle 3 is larger than the outer diameter of the pin 1. The slide 6 and the slider 7 are both T-shaped, and the internal dimensions of the slide 6 match the external dimensions of the slider 7.

[0029] Please see Figures 1 to 4 The lead screw 8 has two opposite external threads, and the lead screw 8 is threadedly connected to the sliders 7 on both sides through the two opposite external threads. The clamping plate 11 is an arc-shaped plate, and the inner diameter of the clamping plate 11 matches the outer diameter of the pin 1. When the lead screw 8 is driven to rotate by the hexagonal head 9, a wrench can be connected through the hexagonal head 9. The lever principle can save the force required to rotate the lead screw 8. When the lead screw 8 rotates, the two opposite external threads can drive the clamping plates 11 on both sides to move closer or further apart, thereby facilitating the clamping or releasing of the pin 1.

[0030] Please see Figures 1 to 4 The support rod 12 is fixedly connected to the sliding seat 10 by bolt installation. The clamping plate 11 has guide rod grooves 13 symmetrically opened on the upper and lower sides near the support rod 12. The pin 1 is fixedly connected to the guide rod 14 on the outer side of the guide rod groove 13. When the clamping plate 11 moves, the guide structure formed by the guide rod groove 13 and the guide rod 14 can guide the movement of the clamping plate 11. At the same time, the clamping plate 11 limits the clamping position of the pin 1, so that the notch 4 of the pin 1 is located between the two clamping plates 11. This ensures that when the clamping plates 11 are close to each other, the outer diameter of the pin 1 can be reduced through the notch 4.

[0031] Working principle: This type of elastic positioning pin, when it is necessary to insert or remove the pin 1, is achieved by rotating the hexagonal head 9 with a wrench. The hexagonal head 9 drives the lead screw 8 to rotate, which in turn drives the two side sliders 7 to move closer together, thereby causing the two side clamping plates 11 to move closer together, compressing the pin 1 and causing it to be compressed through the notch 4. This reduces the outer diameter of the pin 1 to be smaller than the inner diameter of the pin groove, allowing it to be easily inserted into or removed from the connector pin groove. After insertion, rotating the lead screw 8 in the opposite direction releases the elasticity of the pin 1, causing the outer wall of the pin 1 to fit tightly against the inner wall of the connector pin groove. The elastic material itself can absorb external vibration and impact, reducing wear on the connecting parts. At the same time, this positioning pin structure allows the outer diameter of the pin 1 to be reduced during disassembly and assembly, facilitating the removal of the pin. 1. Disassembly and assembly are performed to avoid damage to the pin 1 during disassembly and assembly. When the screw 8 is rotated by the hexagonal head 9, a wrench can be connected through the hexagonal head 9. The lever principle can save the force required to rotate the screw 8. When the screw 8 rotates, the two opposite external threads can drive the two clamping plates 11 to move closer or further apart, which can facilitate clamping or releasing the pin 1. When the clamping plates 11 move, the guide structure formed by the guide rod groove 13 and the guide rod 14 can guide the movement of the clamping plates 11 and limit the clamping position of the pin 1 by the clamping plates 11. The notch 4 of the pin 1 is located between the two clamping plates 11, which can ensure that the outer diameter of the pin 1 can be reduced through the notch 4 when the clamping plates 11 move closer together.

[0032] 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.
