Description

Technical Field

[0001] This utility model relates to the field of mechanical switches, specifically a connection mechanism for a mechanical switch. Background Technology

[0002] At present, mechanical switches have complex structures and numerous parts. The connection methods of the parts are mainly rigid connections and flexible connections. Rigid connections include screw connections and welding, while flexible connections include crank arms and steel wire ropes. Rigid connections are suitable for two adjacent parts, while flexible connections are suitable for two close parts. Because steel wire ropes are rigid and not easy to bend, the connection angle of the connectors cannot be too large.

[0003] As the application scenarios of mechanical switches continue to change and miniaturization requirements increase, the size of mechanical switches is being continuously compressed, and the internal space is very compact. The connection distance between two parts may be far and not in the same direction. Therefore, a high-strength connection mechanism that can continuously shuttle and turn in a narrow space is needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mechanical switch connection mechanism to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A mechanical switch connection mechanism includes a push rod, a push rod connector, a return spring push rod, a return spring, a return spring connector, a spring, a copper tube, a pull rod connector, and a pull rod.

[0007] The push rod is slidably connected to the push rod connector in a limiting manner. The return spring push rod is movably disposed inside the push rod connector and the return spring connector, with one end pre-pressed on the push rod and the other end fitted with the return spring. One end of the return spring connector is connected to the push rod connector, and the other end is connected to one end of the copper tube. One end of the spring is connected to the return spring push rod, and the other end of the spring extends through the inside of the copper tube and connects to the pull rod. The other end of the copper tube is connected to the pull rod connector. The pull rod is slidably connected to the pull rod connector in a limiting manner. By combining the spring and the copper tube, the spring can be folded arbitrarily, and the copper tube can maintain the position of the spring. Due to the small damping coefficient inside the copper tube, the copper tube can also ensure that the spring slides arbitrarily inside the copper tube. The combination of the spring and the copper tube can not only ensure that the connecting mechanism can continuously shuttle and turn in a narrow space, but also further improve the strength and reliability of the connecting mechanism.

[0008] Given the diverse installation locations of internal components and external environments of mechanical switches, and even in situations with limited space, the design ingeniously accommodates the complex connection requirements of mechanical switch components. This allows the connection mechanism to function as an independent component, facilitating easy disassembly, operation from all directions, and enabling convenient maintenance and replacement, thus enhancing the versatility of the connection mechanism.

[0009] Preferably, the push rod and the push rod connector are each provided with corresponding stepped surfaces.

[0010] Preferably, the end of the pull rod has a stepped surface that fits snugly against the pull rod joint.

[0011] Preferably, the spring is made of elastic steel wire.

[0012] Preferably, one end of a copper tube is welded to the other end of the reset spring connector.

[0013] Preferably, a tie rod joint is welded to the other end of the copper tube.

[0014] Preferably, the copper tube is bendable and malleable.

[0015] Compared with the prior art, this utility model discloses a mechanical switch connection mechanism, including a push rod, a push rod connector, a return spring push rod, a return spring, a return spring connector, a spring, a copper tube, a pull rod connector, and a pull rod. These components work together to perform their functions. The combination of the spring and the copper tube allows the spring to be folded arbitrarily, while the copper tube maintains the spring's position. Due to the small damping coefficient inside the copper tube, the copper tube also allows the spring to slide freely inside it. The combination of the spring and the copper tube not only ensures that the connection mechanism can continuously move and turn in a confined space, but also further improves the strength and reliability of the connection mechanism.

[0016] Given the diverse installation locations of internal components and external environments of mechanical switches, and even in situations with limited space, the design ingeniously accommodates the complex connection requirements of mechanical switch components. This allows the connection mechanism to function as an independent component, facilitating easy disassembly, operation from all directions, and enabling convenient maintenance and replacement, thus enhancing the versatility of the connection mechanism.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] A mechanical switch connection mechanism includes a push rod 1, a push rod connector 2, a reset spring push rod 3, a reset spring 4, a reset spring connector 5, a spring 6, a copper tube 7, a pull rod connector 8, and a pull rod 9. The push rod 1 is slidably connected to the push rod connector 2 in a limiting manner. The reset spring push rod 3 is movably disposed within the push rod connector 2 and the reset spring connector 5, with one end pre-pressed onto the push rod 1 and the other end fitted with the reset spring 4. One end of the reset spring connector 5 is connected to the push rod connector 2, and the other end is connected to one end of the copper tube 7. One end of the spring 6 is connected to the reset spring push rod 3, and the other end of the spring 6 extends through the inside of the copper tube 7 and connects to the pull rod 9. The other end of the copper tube 7 is connected to the pull rod connector 8, and the pull rod 9 is slidably connected to the pull rod connector 8 in a limiting manner.

[0022] The push rod 1 and the push rod connector 2 are respectively provided with corresponding stepped surfaces. The end of the pull rod 9 is provided with a stepped surface that fits into the pull rod connector 8. The spring 6 is made of elastic steel wire. The other end of the return spring connector 5 is welded to one end of a copper tube 7. The other end of the copper tube 7 is welded to the pull rod connector 8. The copper tube 7 has bendable and extensible properties.

[0023] Working state: The push rod 1 is pressed against the return spring in the push rod joint 2 and the push rod 3 slides to the right. The return spring push rod 3 slides to the right and compresses the return spring 4, which pushes the spring 6 to slide to the right inside the copper tube 7. The spring 6 pushes the pull rod 9 to slide to the right in the pull rod joint 8, thus completing the corresponding work.

[0024] Reset state: Push rod 1 is not under force. Push rod 3 of the reset spring slides to the left under the push of the release force of the reset spring 4, thereby driving push rod 1 and spring 6 to slide to the left. The sliding of spring 6 to the left drives pull rod 9 to slide to the left in pull rod joint 8 until it stops when the stepped surface at the end of pull rod 9 is limited by pull rod joint 8.

[0025] Bending state: Due to the elasticity of spring 6 and the extensibility of copper tube 7, the connecting mechanism can be bent to any angle and still work normally.

[0026] The left and right directions mentioned above are only for the interpretation of the corresponding attached diagram. In actual work, different perspectives can also be regarded as forward and backward, etc. The directions are only for reference and the actual situation shall prevail, but the structural principle remains unchanged.
