[0002] Relays, as electrical control devices, are widely used in many fields such as power systems, automation control, and electronic equipment. Their working principle is to control the opening and closing of contacts through electromagnetic force, thereby achieving the on / off control of the circuit. In the structure of a relay, the connection mechanism is a crucial component, directly affecting the relay's performance and reliability.

[0003] Traditional relay connection mechanisms typically employ a single-axis hole connection. This method has several drawbacks in practical applications. During assembly, deviations can easily occur, leading to inaccurate positioning of components such as the armature and spring, thus affecting the relay's operational accuracy and stability. Furthermore, a single-axis hole connection may cause uneven stress on components during relay operation, resulting in accelerated contact wear and a shortened relay lifespan.

[0004] In response to the problems raised in the above text, we propose a dual-axis hole connection mechanism for relays. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a dual-axis hole connection mechanism for a relay, including an armature, a push plate, and a spring. Both sides of the push plate are provided with detachably connected dual-rod positioning shafts. The armature and the spring are connected through the push plate.

[0010] According to the above-mentioned relay dual-axis hole connection mechanism, a connecting shaft is rotatably connected to one side of the other knob. The connecting shaft is fixedly connected to a bidirectional threaded rod. A gear is fixedly connected to the outside of the connecting shaft. A sliding groove is provided on the side of the armature and the spring that are far apart from each other. A rack is slidably connected inside the sliding groove. The rack is meshed with the gear. A second spring is fixedly connected inside the sliding groove. The second spring is fixedly connected to the rack.

[0011] According to the above-mentioned dual-axis hole connection mechanism for a relay, the clamping ring is made entirely of rubber and has anti-slip texture on its outer surface.

[0012] According to the above-mentioned dual-axis hole connection mechanism for a relay, the connection assembly includes a mounting bracket, a slide rod is slidably connected inside the mounting bracket, a limit block is fixedly connected to the bottom of the slide rod, a snap-fit ​​block is fixedly connected to the bottom of the limit block, and the snap-fit ​​block snaps into the dual-rod positioning shaft.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] This invention, through its stabilizing components and the connection between the double-rod positioning shaft and the connecting hole, avoids the deviation problems that easily occur during the assembly process of a single-axis hole, preventing issues that could affect relay stability. It also ensures uniform force distribution between components, preventing accelerated contact wear and extending the device's service life. Furthermore, by rotating the knob to drive the bidirectional threaded rod, the double-rod threaded rod moves the two sliders in opposite directions, thereby clamping and limiting the double-rod positioning shaft, further improving the stability of the device connection.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: Refer to Figures 1 to 4 A relay dual-axis hole connection mechanism includes an armature 1, a push plate 2 and a spring 3. Both sides of the push plate 2 are provided with a detachably connected dual-rod positioning shaft 22. The armature 1 and the spring 3 are connected through the push plate 2. The side of the armature 1 and the spring 3 that are close to each other are provided with a connection hole 21, which matches the dual-rod positioning shaft 22.

[0025] Stabilizing components are provided on the sides of armature 1 and spring 3 that are far apart from each other, and a connecting component is provided on the top of push plate 2. The stabilizing components can improve the connection stability between the components, thereby increasing the service life of the device. Furthermore, the connecting component can be used to replace the double rod positioning shaft 22 when it is severely worn, so as to ensure the connection stability between the devices.

[0026] The stabilizing assembly includes two mounting blocks 11, with a bidirectional threaded rod 13 rotatably connected between them. A knob 12 is rotatably connected to one side of one mounting block 11, and the knob 12 is fixedly connected to the bidirectional threaded rod 13. Two sliders 14 are threadedly connected to the outer side of the bidirectional threaded rod 13. Clamping rings 15 are fixedly connected to the sides of the two sliders 14 that are close to each other. The clamping rings 15 contact or separate from the double-rod positioning shaft 22. The knob 12 drives the bidirectional threaded rod 13 to rotate, which in turn moves the two sliders 14, thereby causing the clamping rings 15 to contact the double-rod positioning shaft 22 and limit its movement. A connecting shaft 16 is rotatably connected to one side of the other knob 12, and the connecting shaft 16 is fixedly connected to the bidirectional threaded rod 13. A gear 17, an armature 1, and a spring are fixedly connected to the outer side of the connecting shaft 16. 3. Each of the two sides away from each other is provided with a sliding groove 31. A rack 33 is slidably connected inside the sliding groove 31. The rack 33 is meshed with the gear 17. A second spring 32 is fixedly connected inside the sliding groove 31. The second spring 32 is fixedly connected with the rack 33. While the clamping ring 15 limits the positioning shaft 22 of the double rod, in order to prevent the bidirectional threaded rod 13 from reversing, the rack 33 meshes with the gear 17 to limit and fix the bidirectional threaded rod 13, thus avoiding the unstable connection between the components caused by reversal. The clamping ring 15 is made of rubber and has anti-slip texture on its outer surface. Making the clamping ring 15 of rubber can increase the friction between it and the double rod positioning shaft 22, further improving stability. The anti-slip texture on its outer surface can further improve the stability of the connection.

[0027] The connecting assembly includes a mounting bracket 23, with a sliding rod 24 slidably connected inside the mounting bracket 23. A limit block 26 is fixedly connected to the bottom of the sliding rod 24, and a locking block 25 is fixedly connected to the bottom of the limit block 26. The locking block 25 engages with the double-rod positioning shaft 22. The sliding rod 24 drives the limit block 26 and the locking block 25 to move upward, thereby releasing the engagement between the locking block 25 and the double-rod positioning shaft 22. Subsequently, the double-rod positioning shaft 22 can be replaced. A spring 27 is fixedly connected to the top of the limit block 26. The spring 27 is fixedly connected to the mounting bracket 23, and the sliding rod 24 is located inside the spring 27 and does not contact it. During installation, after the double-rod positioning shaft 22 is inserted into the push plate 2, the locking block 25 resets under the action of the spring 27 and can engage with the double-rod positioning shaft 22, making the disassembly and connection of the double-rod positioning shaft 22 more convenient.

[0028] The working principle of this utility model is as follows: By connecting the double-rod positioning shaft 22 with the connecting hole 21, the problem of deviation that easily occurs during the assembly process of a single-rod hole is avoided. During connection, the double-threaded rod 13 is driven to rotate by the knob 12, which drives the two sliders 14 to move, and the clamping ring 15 contacts the double-rod positioning shaft 22 and limits and fixes it, thereby improving the connection stability between the components. At the same time, in order to further improve stability, the rack 33 can mesh with the gear 17 to complete the limit and fixation of the double-threaded rod 13, avoiding the situation of unstable connection between the components due to reverse rotation. Thus, during use, the force between the components is kept uniform, avoiding the problem of accelerated wear of the contact points. During use, the double-rod positioning shaft 22 can be replaced. During the replacement process, the sliding rod 24 drives the limiting block 26 and the locking block 25 to move upward, thereby releasing the locking relationship between the locking block 25 and the double-rod positioning shaft 22. Then, the double-rod positioning shaft 22 can be replaced, and the replacement is convenient.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
