Oscillating structure stable wall switch

Abstract

A stable swing-type wall switch utilizes a spring groove with an upper groove, a lower groove, and an inclined section in the swing arm. A spring is installed within the groove. When the switch plate swings, both ends of the spring connect to the upper groove wall and the switch plate, respectively, while the middle part fits against the inclined groove wall. This structure guides and limits the spring's extension and contraction path during deformation under stress, allowing it to move stably along a preset trajectory and preventing lateral deviation or twisting. Simultaneously, the spring force is buffered and transmitted through the inclination angle of the inclined section, making the swing of the swing arm smoother and reducing issues such as switch operation jamming or abnormal noise caused by spring instability. This effectively improves the stability and lifespan of the entire wall switch's swing structure.

Description

Technical Field

[0001] This utility model relates to the field of switch and electrical appliance technology, specifically to a wall switch with a stable swing structure. Background Technology

[0002] The rocker arm in a wall switch acts as the transmission component between the switch button and the rocker plate. Its stability directly affects the switch's lifespan and operational feel during long-term use. Currently available rocker arms typically have a spring groove in the center with a spring connecting the rocker plate. However, the existing spring groove structure is simple. During oscillation, the spring, after being twisted by force, cannot properly fit against the groove wall. This causes the spring to easily shift or jam during repeated deformation, leading to increased oscillation resistance, uneven return to its original position, and even poor switch contact. Utility Model Content

[0003] In view of this, the present invention provides a wall switch with a stable swing structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

A jumper is disposed within the switch box, and a swing rod is disposed between the switch panel and the jumper. One end of the swing rod is connected to the switch panel, and the other end extends into the switch box and connects to the jumper. The swing rod has a swing portion and a rod body portion. The swing portion is connected to the switch panel, and the rod body portion extends into the switch box and connects to the jumper. A spring groove is formed on the rod body portion along its height direction. The spring groove has an upper groove portion, a lower groove portion, and an inclined portion connecting the upper and lower groove portions. The two ends of the inclined portion are respectively connected to the upper and lower groove portions. A spring is disposed within the spring groove. One end of the spring extends into the upper groove portion and abuts against the groove wall of the upper groove portion, while the other end of the spring extends out of the spring groove and connects to the jumper. During the swinging process of the jumper, the spring is deformed by force, and the middle part of the spring fits against the groove wall of the inclined portion.

[0009] Preferably, the swinging part is disposed at the top of the rod body, and the switch box is opened on the cover. The cover is opened with a swing rod groove corresponding to the swinging part. The swinging part is rotatably disposed in the swing rod groove. One end of the rod body passes through the cover and extends into the switch box to connect with the jump plate.

[0011] Preferably, the bracket positioning plate has a recessed groove formed on the side of the end face away from the switch box, and the swing rod partially extends into the recessed groove.

[0012] The beneficial effects of this utility model are as follows: By creating a spring groove with an upper groove, a lower groove, and an inclined section in the rod body of the swing arm, and placing a spring inside the groove, when the spring plate swings, both ends of the spring are connected to the upper groove wall and the spring plate respectively, while the middle part fits against the inclined groove wall. This structure ensures that the spring's extension and contraction path is guided and limited by the inclined section during deformation under stress, enabling it to move stably along a preset trajectory and preventing lateral deviation or twisting of the spring.

[0019] 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.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] This utility model provides the following technical solution:

[0022] As attached Figure 1-5As shown, this utility model discloses a wall switch with a stable swing structure, including a switch box 1 and a switch panel 2. A jumper 3 is disposed inside the switch box 1. A swing rod 4 is disposed between the switch panel 2 and the jumper 3. One end of the swing rod 4 is connected to the switch panel 2, and the other end of the swing rod 4 extends into the switch box 1 and connects to the jumper 3. The swing rod 4 has a swinging part 5 and a rod body 6. The swinging part 5 is connected to the switch panel 2, and the rod body 6 extends into the switch box 1 and connects to the jumper 3. A groove is formed on the rod body 6 along... A spring groove 7 is provided along the height of the rod body 6. The spring groove 7 has an upper groove 8, a lower groove 9, and an inclined portion 10 connecting the upper groove 8 and the lower groove 9. The two ends of the inclined portion 10 are respectively connected to the upper groove 8 and the lower groove 9. A spring is installed in the spring groove 7. One end of the spring extends into the upper groove 8 and abuts against the groove wall of the upper groove 8. The other end of the spring extends out of the spring groove 7 and connects with the springboard 3. During the swing of the springboard 3, the spring is deformed by force, and the middle part of the spring fits against the groove wall of the inclined portion 10. Specifically, in this design, a spring groove 7 with an upper groove 8, a lower groove 9, and an inclined portion 10 is opened in the rod body 6 of the swing rod 4, and a spring is installed in the groove. When the springboard 3 swings, the two ends of the spring are connected to the groove wall of the upper groove 8 and the springboard 3 respectively, and the middle part fits against the groove wall of the inclined portion 10. This structure ensures that the spring's extension and contraction path is guided and limited by the inclined part 10 during deformation under stress, allowing it to move stably along a preset trajectory and preventing lateral deviation or twisting. Simultaneously, the spring's elastic force is buffered and transmitted through the tilt angle of the inclined part 10, making the swing of the lever 4 smoother and reducing issues such as switch operation jamming or abnormal noise caused by spring instability. This effectively improves the stability and lifespan of the entire wall switch swing structure.

[0023] Furthermore, a positioning rib structure 11 protrudes from the side of the upper groove 8 away from the lower groove 9. One end of the spring extends into the upper groove 8 and abuts against the positioning rib, while the other end of the spring passes through the inclined portion 10 and extends into the lower groove 9. One end of the jumper 3 extends into the lower groove 9 and connects with the spring. Specifically, in this embodiment, the positioning rib structure 11 can precisely limit the end of the spring, preventing the spring from falling off the groove wall during the stress process, further enhancing the stability of the spring installation. At the same time, the other end of the spring passes through the inclined portion 10 and extends into the lower groove 9 to connect with the jumper 3, so that the overall extension and contraction stroke of the spring is strictly limited within the space of the spring groove 7, avoiding plastic deformation of the spring due to excessive stretching or compression. When the spring is driven to move by the spring plate 3, the abutment between the positioning rib and the end of the spring, combined with the guiding effect of the inclined part 10 on the middle of the spring, forms a multi-directional constraint mechanism, ensuring that the spring always performs elastic deformation along the preset trajectory, thereby making the swing action of the lever 4 smoother and more reliable, and effectively reducing the failure rate of the switch during long-term use.

[0024] Furthermore, the inclined portion 10 has a trapezoidal cross-sectional shape. The maximum inner diameter of the inclined portion 10 is the same as the inner diameter of the lower groove 9, and the minimum inner diameter of the inclined portion 10 is the same as the inner diameter of the upper groove 8. Specifically, in this embodiment, the inclined portion 10 is designed with a trapezoidal cross-section, and its inner diameter gradually transitions from the minimum inner diameter of the upper groove 8 to the maximum inner diameter of the lower groove 9. This gradual structure provides a smoother transition space for the deformation of the spring. When the spring moves within the inclined portion 10, the trapezoidal sidewalls generate a uniform lateral support force on the spring, preventing the spring from deflecting due to uneven radial force during extension and contraction. At the same time, the trapezoidal cross-section causes the contact area between the groove wall of the inclined portion 10 and the spring to gradually change with the movement of the spring, ensuring that the spring maintains a stable contact state at different deformation stages, further improving the guiding accuracy of the spring movement, thereby enhancing the smoothness of the swing of the rocker arm 4 and the overall reliability of the structure.

[0025] Furthermore, a reinforcing rib structure 12 is provided between each end face of the rod body 6 and the bottom surface of the swing part 5, and the reinforcing rib structure 12 is connected to the swing part 5 and the rod body 6 respectively. Specifically, in this embodiment, the setting of the reinforcing rib structure 12 can significantly improve the overall structural strength and deformation resistance of the swing rod 4. When the swing rod 4 is subjected to external force during the switch operation, the reinforcing rib can disperse the stress from the connection position between the swing part 5 and the rod body 6 to a larger area, avoiding the breakage or bending of the swing rod 4 due to local stress concentration. At the same time, the tight connection between the reinforcing rib and the swing part 5 and the rod body 6 forms a stable triangular support structure, which further enhances the rigidity of the swing rod 4 during the swing process, reduces the swaying caused by deformation, and makes the movement trajectory of the swing rod 4 more accurate, thereby ensuring that the operating feel of the wall switch remains consistent and extending the service life of the switch.

[0026] Furthermore, the swinging part 5 is disposed at the top of the rod part 6, and a cover 13 is formed on the switch box 1. A swing rod groove 14 corresponding to the swinging part 5 is formed on the cover 13. The swinging part 5 is rotatably disposed in the swing rod groove 14. One end of the rod part 6 passes through the cover 13 and extends into the switch box 1 to connect with the jump plate 3. The edge of the swing rod groove 14 is recessed to form a side groove 15. The swinging part 5 protrudes from the side groove 15 to form a positioning end 21, which extends into the side groove 15. Specifically, in this embodiment, the setting of the swing rod groove 14 provides a stable rotation space for the swinging part 5, while the setting of the side groove 15 allows the overall position of the swing rod 4 to be recessed, thereby further reducing the overall thickness of the switch, which meets the design requirements of modern home appliances for thin and light switches. At the same time, the cooperation between the positioning end 21 and the side groove 15 can circumferentially limit the swing rod 4 during swinging, preventing the swing rod 4 from axially shifting or shaking, and ensuring that the swinging part 5 always rotates smoothly within the preset trajectory. This structural design not only enhances the overall aesthetics of the switch, but also further strengthens the stability of the swing structure by precisely constraining the position of the lever 4, making the switch operation smoother and effectively avoiding problems such as poor contact caused by misalignment of the lever 4.

[0027] Furthermore, a bracket assembly is also provided on the switch box 1. The bracket assembly includes a bracket positioning plate 16 and a bracket body 17. One end of the swing rod 4 passes through the bracket positioning plate 16 and extends into the switch box 1 to connect with the jump plate 3. The bracket positioning plate 16 has a recessed end face near the switch box 1 to form a bracket positioning groove 18. The bracket is embedded in the bracket positioning groove 18 and snap-fitted to the bracket positioning plate 16. The bracket extends towards the switch box 1 to form a box body connecting part 20, which is snap-fitted to the switch box 1. Specifically, in this embodiment, the bracket positioning plate 16 is snap-fitted to the bracket body 17 through the bracket positioning groove 18. This connection method is not only convenient to install, but also ensures the relative positional accuracy between the bracket assembly and the switch box 1. The snap-fit ​​between the box body connecting part and the switch box 1 further securely fixes the bracket assembly to the switch box 1, preventing the bracket from loosening or shifting during switch use. Meanwhile, the bracket assembly can also isolate the swing arm 4 from other components inside the switch box 1, preventing the swing arm 4 from interfering with other structures when it moves, thereby further improving the stability and reliability of the entire swing structure and ensuring that the switch can work stably for a long time.

[0028] Furthermore, the bracket positioning plate 16 is recessed on the side of its end face away from the switch box 1 to form a clearance groove 19, and the swing rod 4 partially extends into the clearance groove 19. Specifically, in this embodiment, the clearance groove 19 provides sufficient space for the movement of the swing rod 4, avoiding direct contact and friction between the swing rod 4 and the bracket positioning plate 16 during swinging. When the swing rod 4 rotates, its partial structure can move freely within the clearance groove 19, effectively reducing mechanical interference between components. This design not only reduces the resistance during the movement of the swing rod 4, making the switch operation more convenient and smooth, but also avoids wear and abnormal noise caused by friction, extending the service life of the swing rod 4 and the bracket positioning plate 16. At the same time, the recessed structure of the clearance groove 19 also makes the connection between the swing rod 4 and the bracket positioning plate 16 more compact, which helps to further optimize the overall spatial layout of the switch and meet the design requirements of product miniaturization and thinness.

[0029] Specifically, the snap-fit ​​connection methods in this design can all adopt the elastic snap-fit ​​structure commonly used in existing technologies. For example, by setting protruding hooks and corresponding slots to cooperate, quick assembly and disassembly between components can be achieved, so it will not be elaborated here.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
