Multi-angle bolt

Abstract

The utility model relates to the field of locks, in particular to a multi-angle bolt which is pushed to move along a guide sliding groove and compresses a first elastic piece during locking. When the limiting groove in the bolt moves to the position of the first through hole corresponding to the limiting piece, the limiting piece is clamped into the limiting groove under the action of the second elastic piece, and locking of the bolt is achieved. At the moment, the movable end of the bolt is inserted into the inserting hole of the second connecting seat, connection is completed, and a fixed state is achieved. When unlocking is needed, the button is pressed downwards, and the button pushes the limiting piece to move downwards, so that the limiting piece is separated from the limiting groove of the bolt. At the moment, the first elastic piece recovers deformation, the plug pin is pushed to move in the direction away from the second connecting base, the movable end of the plug pin is made to retreat from the inserting hole, and therefore rapid unlocking and separation are achieved. The problems that most of existing plug pins are designed to be of a fixed structure, can only be installed and used at a specific angle or in a specific direction and are difficult to meet the multi-angle and multi-direction assembly requirements are solved.

Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a multi-angle bolt. Background Technology

[0002] Pins, as common and crucial connecting and fixing components, are widely used in modern architecture, furniture assembly, and electrical connection structures. Traditional pins are typically made of metal or plastic, and their basic function is to achieve a secure connection between two or more components. However, with the increasing complexity and diversity of application scenarios, existing pins have gradually revealed some limitations. Most existing pins are designed with a fixed structure, allowing installation and use only at specific angles or directions, making it difficult to adapt to multi-angle and multi-directional assembly needs. For example, in environments with irregular structural connections, fixed inclined surfaces, or limited space, traditional pins often cannot flexibly adjust their angle, leading to installation difficulties, weak connections, and even affecting the stability and aesthetics of the overall structure.

[0003] Therefore, there is an urgent need for a multi-angle latch that can be flexibly adjusted and securely connected at different angles and directions. Utility Model Content

[0004] To address the problem that most existing latches are designed with a fixed structure, allowing installation and use only at specific angles or directions, making it difficult to adapt to multi-angle and multi-directional assembly needs.

[0005] This utility model provides a multi-angle pin, including a first connecting seat, a second connecting seat, and a pin; the first connecting seat is provided with a guide groove, a first elastic element, and a button, a limiting piece and a second elastic element are installed in the guide groove, the second elastic element is located at the bottom of the limiting piece, the button is located at the top of the limiting piece, the limiting piece is provided with a first through hole, the connecting end of the pin passes through the first through hole and is connected to one end of the first elastic element, the other end of the first elastic element is connected to the first connecting seat; the second connecting seat is provided with a insertion hole for accommodating the movable end of the pin; the pin is provided with a limiting groove for engaging the limiting piece.

[0006] Preferably, the connecting end of the pin is provided with a limiting protrusion ring, the limiting groove and the limiting protrusion ring are respectively located on both sides of the limiting piece, the diameter of the limiting protrusion ring is larger than the diameter of the first through hole, and the limiting protrusion ring abuts against the first elastic element.

[0007] Preferably, the first connecting seat includes a cover plate and a base plate, the cover plate is connected to the top of the base plate, the button is located on the cover plate, the guide groove is located on the base plate, and the two ends of the second elastic member are respectively connected to the bottom of the base plate and the limiting piece.

[0008] Preferably, the bottom plate has a first guide plate and a second guide plate at its two ends, the first guide plate has a first guide hole, the second guide plate has a second guide hole, and the movable end of the pin passes through the first guide hole, the first through hole and the second guide hole in sequence.

[0009] Preferably, the top of the limiting piece has a protrusion, and the button cover fits onto the protrusion.

[0010] Preferably, both the first elastic element and the second elastic element are springs.

[0011] Preferably, the first connecting seat, the second connecting seat, and the pin are all made of rust-resistant alloy.

[0012] The beneficial effects of this invention are as follows: When the pin is pushed, it moves along the guide groove in the first connecting seat and compresses the first elastic element. During this process, the limiting piece, under the elastic force of the second elastic element, always presses upward against the pin. When the limiting groove on the pin moves to the position of the first through hole corresponding to the limiting piece, the limiting piece is engaged in the limiting groove under the action of the second elastic element, thus locking the pin. Since the limiting piece is installed in the guide groove, it can only move up and down within the guide groove and cannot move horizontally, thus maintaining a stable engagement with the limiting groove and preventing the pin from loosening or falling off. At this time, the movable end of the pin has been inserted into the socket of the second connecting seat, completing the connection and being in a fixed state. When unlocking is required, the button is pressed down, and the button pushes the limiting piece downward, causing it to disengage from the limiting groove of the pin. At this time, the first elastic element returns to its original shape, pushing the pin away from the second connecting seat, causing the movable end of the pin to exit from the socket, thereby achieving quick unlocking and separation. The entire process is simple to operate and the connection is reliable, suitable for assembly needs at various angles and directions. It solves the problem that most existing pins are fixed in structure and can only be installed and used at specific angles or directions, making it difficult to adapt to multi-angle and multi-directional assembly needs.

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Reference Figures 1-2 A multi-angle latch includes a first connecting seat 1, a second connecting seat 2, and a latch 3. The first connecting seat 1 is provided with a guide groove 11, a first elastic element 12, and a button 13. A limiting piece 14 and a second elastic element 15 are installed in the guide groove 11. The second elastic element 15 is located at the bottom of the limiting piece 14. The button 13 is located at the top of the limiting piece 14. The limiting piece 14 is provided with a first through hole 141. The connecting end 31 of the latch 3 passes through the first through hole 141 and is connected to one end of the first elastic element 12. The other end of the first elastic element 12 is connected to the first connecting seat 1. The second connecting seat 2 is provided with a insertion hole for accommodating the movable end 32 of the latch 3. The latch 3 is provided with a limiting groove 311 for engaging the limiting piece 14.

[0018] When the pin 3 is pushed, the pin 3 moves along the guide groove 11 in the first connecting seat 1 and compresses the first elastic member 12. During this process, the limiting piece 14 is always pressed upward against the pin 3 by the elastic force of the second elastic member 15. When the limiting groove 311 on the pin 3 moves to the position of the first through hole 141 corresponding to the limiting piece 14, the limiting piece 14 is engaged in the limiting groove 311 by the action of the second elastic member 15, thereby locking the pin 3. Since the limiting piece 14 is installed in the guide groove 11, the limiting piece 14 can only move up and down in the guide groove 11 and cannot move horizontally, so it can stably maintain the engaged state with the limiting groove 311 and prevent the pin 3 from loosening or falling off. At this time, the movable end 32 of the pin 3 has been inserted into the insertion hole of the second connecting seat 2, completing the connection and being in a fixed state. When unlocking is required, the button 13 is pressed down, and the button 13 pushes the limiting piece 14 downward, causing it to disengage from the limiting groove 311 of the pin 3. At this point, the first elastic element 12 recovers its deformation, pushing the pin 3 away from the second connecting seat 2, causing the movable end 32 of the pin 3 to exit the socket, thus achieving quick unlocking and separation. The entire process is simple to operate, reliable in connection, and suitable for assembly needs at various angles and directions. It solves the problem that most existing pins are designed with a fixed structure, which can only be installed and used at specific angles or directions, making it difficult to adapt to assembly needs at multiple angles and directions.

[0019] In some embodiments, the connecting end 31 of the pin 3 is provided with a limiting protrusion 312. The limiting groove 311 and the limiting protrusion 312 are respectively located on both sides of the limiting piece 14. The diameter of the limiting protrusion 312 is larger than the diameter of the first through hole 141. The limiting protrusion 312 abuts against the first elastic member 12.

[0020] Reference Figure 2 By setting a limiting protrusion ring 312, the pin 3 is prevented from being completely pulled out of the first connecting seat 1, ensuring that the pin 3 is always connected to the first connecting seat 1, thus avoiding loss or safety hazards.

[0021] In some embodiments, the first connecting seat 1 includes a cover plate 16 and a base plate 17. The cover plate 16 is connected to the top of the base plate 17. The button 13 is provided on the cover plate 16. The guide groove 11 is provided on the base plate 17. The two ends of the second elastic member 15 are respectively connected to the bottom of the base plate 17 and the bottom of the limiting piece 14.

[0022] Reference Figure 2 The first connecting seat 1 is divided into two parts: a cover plate 16 and a base plate 17, which facilitates the assembly and maintenance of the first connecting seat 1. Specifically, a detachable connection is formed by setting corresponding threaded holes on the cover plate 16 and the base plate 17.

[0023] Preferably, the bottom plate 17 is provided with a first guide plate 171 and a second guide plate 172 at both ends. The first guide plate 171 is provided with a first guide hole, and the second guide plate 172 is provided with a second guide hole. The movable end 32 of the pin 3 passes through the first guide hole, the first through hole 141 and the second guide hole in sequence.

[0024] Reference Figure 2 By setting the first guide hole and the second guide hole, a double-point support guide is formed for the movement path of the pin 3; effectively preventing the pin 3 from deflecting, shaking or getting stuck during the movement, and ensuring its smooth and stable sliding.

[0025] In some embodiments, the top of the limiting piece 14 is provided with a protrusion 142, and the button 13 covers the protrusion 142.

[0026] Reference Figure 2 By setting the protrusion 142, the connection between the limiting piece 14 and the button 13 is made more stable. When the button 13 is pressed, the button 13 directly acts on the protrusion 142 on the top of the limiting piece 14, ensuring that the pressing force is accurately transmitted to the limiting piece 14, so that the limiting piece 14 can move down smoothly and disengage from the limiting groove 311 on the pin 3.

[0027] In some embodiments, both the first elastic element 12 and the second elastic element 15 are springs.

[0028] As a common elastic element, springs can provide stable and predictable elastic force, making them easy to maintain and replace.

[0029] In some embodiments, the first connecting seat 1, the second connecting seat 2, and the pin 3 are all made of rust-resistant alloy.

[0030] The rust-resistant alloy possesses excellent corrosion resistance, effectively preventing rusting in humid or harsh environments. This allows the multi-angle pin 3 to be used in a wider range of environmental conditions, increasing its versatility and market competitiveness.
