Description

Technical Field

[0001] This utility model relates to the field of radiometric measuring instruments, and in particular to a spring pin. Background Technology

[0002] As a core locking component in structures such as doors, windows, and cabinets, bolts are widely used in furniture, warehousing, and construction. Most existing bolts employ a purely manual insertion and removal mechanism, lacking a flexible reset mechanism. Operation requires manual alignment of the keyhole throughout, which is inconvenient, especially when holding objects with both hands or in confined spaces. Furthermore, some bolts lack sufficient locking reliability. Relying on a single mechanical locking mechanism, bolts are prone to loosening under vibration, external impact, and other factors, posing safety hazards. Therefore, we propose a spring-loaded bolt. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a spring-loaded latch. This utility model solves the problem that most existing latches employ a purely manual insertion and removal structure, lacking an elastic reset mechanism. During operation, manual alignment of the latch hole is required throughout the process, which is particularly inconvenient in situations where both hands are holding objects or in confined spaces. Furthermore, some latches lack sufficient locking reliability, and the latches rely on a single mechanical locking mechanism, making them prone to loosening under vibration, external impact, or other factors, posing a safety hazard.

[0004] A spring pin according to this utility model includes a base, a mounting groove on one side of the base, a guide groove on the side of the base located in the mounting groove, a pin plate in the guide groove, one end of the pin plate located in the mounting groove being fixedly connected to a fixing plate, a sleeve in the middle of the fixing plate, a push plate fixedly connected above the fixing plate, a back plate fixedly connected to the side of the base away from the guide groove, a positioning rod in the middle of the side of the back plate near the base, a spring sleeved on the outside of the positioning rod, and the spring extending into the sleeve on the side away from the back plate.

[0005] In the above scheme, the base is fixedly welded to the back plate.

[0006] In the above scheme, the upper end of the back plate is provided with first mounting holes on both sides.

[0007] In the above solution, a second mounting hole is provided on both sides of the base.

[0008] In the above solution, the base is provided with a clearance groove that matches the sleeve.

[0009] In the above scheme, anti-slip textures are provided on both sides of the push plate.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a spring pin. When the spring pin is locking, under the action of the spring force, the sleeve drives the fixed plate and the pin plate to move, so that the pin plate automatically inserts into the locking part. When unlocking is required, when the push plate is pushed, the push plate drives the fixed plate and the sleeve to move horizontally, and the pin plate disengages from the locking part, thereby unlocking the locking part. This spring pin can realize the extension and retraction of the pin plate by pushing the push plate to complete the locking and unlocking operations. The operation process is simple and labor-saving. The pin plate slides in the guide groove. The overall structure is reasonably designed, has high stability, and is not prone to jamming after long-term use. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] like Figure 1-3As shown, this utility model is a spring pin, including a base 1. A mounting groove 2 is provided on one side of the base 1. A guide groove 3 is provided on the side of the base 1 adjacent to the mounting groove 2. A pin plate 4 is provided within the guide groove 3. The guide groove 3 guides and limits the pin plate 4, allowing it to move stably horizontally. One end of the pin plate 4 within the mounting groove 2 is fixedly connected to a fixing plate 5. A sleeve 6 is provided in the middle of the fixing plate 5. A push plate 7 is fixedly connected to the top of the fixing plate 5. The side of the base 1 away from the guide groove 3 is fixed to a back plate 8. The back plate 8 is connected to the base 1, and a positioning rod 9 is provided in the middle of the side of the back plate 8. A spring 10 is sleeved on the outside of the positioning rod 9. The spring 10 extends into the sleeve 6 on the side away from the back plate 8. When the spring pin is locked, the sleeve 6 moves the fixing plate 5 and the pin plate 4 under the action of the spring force of the spring 10, so that the pin plate 4 is automatically inserted into the locking part. When it is necessary to unlock, when the push plate 7 is pushed, the push plate 7 moves the fixing plate 5 and the sleeve 6 in the horizontal direction, and the pin plate 4 disengages from the locking part, thereby unlocking the locking part.

[0018] The base 1 is fixedly welded to the back plate 8. Welding ensures the firmness of the connection between the base 1 and the back plate 8 and improves the structural stability of the entire spring pin.

[0019] The back plate 8 has first mounting holes 11 on both sides of its upper end. The first mounting holes 11 facilitate fixing the spring pin to the vertical surface with bolts or other connecting parts, increasing the diversity of installation methods.

[0020] The base 1 has second mounting holes 12 on both sides. The second mounting holes 12 facilitate fixing the spring pin on the horizontal surface, so that the pin can adapt to different installation scenarios and improve its applicability.

[0021] The base 1 is provided with a clearance groove 13 that matches the sleeve 6. The clearance groove 13 can provide space for the movement of the sleeve 6, avoid interference between the sleeve 6 and the base 1 when the fixed plate 5 moves, and ensure the smooth sliding of the pin plate 4.

[0022] Both sides of the push plate 7 are provided with anti-slip textures, which can increase the friction between the hand and the push plate 7, making it easier for the operator to push the push plate 7 to perform the insertion and removal of the pin, thus improving the convenience of operation.

[0023] Specifically, in this utility model, when the spring pin is locking, under the action of the spring force of the spring 10, the sleeve 6 drives the fixing plate 5 and the pin plate 4 to move, so that the pin plate 4 automatically inserts into the locking part. When unlocking is required, when the push plate 7 is pushed, the push plate 7 drives the fixing plate 5 and the sleeve 6 to move horizontally, and the pin plate 4 disengages from the locking part, thereby unlocking the locking part. The guide groove 3 can guide and limit the pin plate 4, so that the pin plate 4 can move horizontally stably in the horizontal direction. The clearance groove 13 can provide space for the movement of the sleeve 6, avoid the sleeve 6 from interfering with the base 1 when it moves with the fixing plate 5, and ensure the smooth sliding of the pin plate 4.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
