Description

Technical Field

[0001] This utility model relates to the field of switch and electrical appliance technology, specifically to a base for wall switch sockets. Background Technology

[0002] In existing technologies, the installation of wall switch and socket bases generally suffers from poor stability. Many traditional bases, during installation, do not have a tight enough fit between the screws and the carrier, or between the base and the socket itself, making them prone to loosening or displacement. This not only affects the normal use of the switch and socket and reduces its lifespan, but may even pose safety hazards. Utility Model Content

[0003] In view of this, the present invention provides a base for wall switch sockets.

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

[0005] A base for a wall switch socket includes a base body with a mounting hole. The mounting hole has an annular stepped portion protruding from its wall. The mounting hole has an outer hole on one side of the annular stepped portion and an inner hole on the inner ring side of the annular stepped portion. The annular stepped portion has an annular surface that connects with the inner walls of the outer hole and the inner hole. The annular surface has a high position and a low position, and a screw limiting groove is formed on the low position.

[0006] Preferably, the lower part is connected to the higher part, and the height of the lower part gradually increases from the side away from the higher part toward the higher part until it is level with the higher part.

[0007] Preferably, the screw limiting groove is formed on the lower part and extends along the edge of the inner hole toward the higher part, so that a portion of the screw limiting groove is formed on the higher part.

[0008] Preferably, the junction between the lower part and the higher part is located on one side of the center of the mounting hole.

[0009] Preferably, the screw limiting groove is wrench-shaped, and the opposite side walls of the screw limiting groove are arc-shaped.

[0010] Preferably, a disassembly / reassembly indicator is provided on the portion of the base body near the mounting hole, with one end of the disassembly / reassembly indicator pointing towards the mounting hole.

[0011] Preferably, the outer and inner portions of the mounting hole are coaxially arranged elliptical shapes.

[0012] The beneficial effects of this utility model are as follows: By designing the annular surface with a high and low section, when the base is installed on the carrier, the screw is tilted after entering the mounting hole. This increases the friction and engagement force between the screw, the carrier, and the base, improving the stability and firmness of the base installation. Simultaneously, the screw-limiting groove on the low section further limits the screw, preventing loosening or displacement during use. When the screw is tilted and installed in the mounting hole, its head contacts the high section of the annular surface, while the screw shaft passes through the inner hole and penetrates deep into the carrier. This tilted installation method creates a more complex force-bearing structure between the screw and the carrier, providing better resistance to external pulling and vibration compared to traditional vertical installation. Moreover, even under certain external forces during long-term use, the screw is less likely to come out of the mounting hole due to the annular stepped section and the screw-limiting groove, thus ensuring the normal use and safety of the wall switch socket base. In addition, this unique mounting hole design can adapt to the unevenness of different carrier surfaces to a certain extent. When there are slight unevennesses on the carrier surface, the tilted screws can still be well connected with the carrier, ensuring the reliability of the base installation.

[0017] 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.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model provides the following technical solution:

[0020] As attached Figure 1-3 As shown, this utility model discloses a base for a wall switch socket, comprising a base body 1. The base body 1 has a mounting hole 2. The outer hole portion 5 and the inner hole portion 4 of the mounting hole 2 are coaxially arranged in an elliptical shape. An annular stepped portion 3 protrudes from the wall of the mounting hole 2. The mounting hole 2 has an outer hole portion 5 located on one side of the annular stepped portion 3 and an inner hole portion 4 located on the inner ring side of the annular stepped portion 3. The annular stepped portion 3 has an annular surface 6 that connects with the inner walls of the outer hole portion 5 and the inner wall of the inner hole portion 4. The annular surface 6 has a high position portion 7 and a low position portion 8. A screw limiting groove 9 is formed on the low position portion 8. Specifically, in this design, by setting the annular surface 6 to have a high position portion 7 and a low position portion 8, when the base is installed on the carrier, after the screw extends into the mounting hole 2, the screw is in an inclined state, thereby increasing the friction and engagement force between the screw and the carrier and the base, improving the stability and firmness of the base installation. Meanwhile, the screw limiting groove 9 on the lower part 8 further limits the screw, preventing it from loosening or shifting during use. When the screw is installed at an angle in the mounting hole 2, its head contacts the higher part 7 of the annular surface 6, while the screw shaft passes through the inner hole 4 and penetrates into the carrier. This angled installation method creates a more complex force-bearing structure between the screw and the carrier, which better resists external pulling and vibration compared to the traditional vertical installation method. Moreover, even under certain external forces during long-term use, the screw is not easily dislodged from the mounting hole 2 due to the presence of the annular stepped part 3 and the screw limiting groove 9, thus ensuring the normal use and safety of the wall switch socket base. In addition, this unique mounting hole 2 design can adapt to the unevenness of different carrier surfaces to a certain extent. When the carrier surface has slight unevenness, the angled screw can still be well bonded to the carrier, ensuring the reliability of the base installation.

[0021] Specifically, the arrangement of the high part 7 and the low part 8 ensures that the screw contacts the high part first during installation, so that the high part 7 is stressed first, distributing the stress to a larger area of ​​the annular stepped part 3 and the base body 1, thus avoiding stress concentration that could cause damage or deformation to the base.

[0022] Furthermore, the lower portion 8 is connected to the higher portion 7, and the height of the lower portion 8 gradually increases from the side away from the higher portion 7 towards the higher portion 7 until it is flush with the higher portion 7. Specifically, in this embodiment, this gradually changing height design of the lower portion 8 allows the screw to transition more smoothly from the lower portion 8 to the higher portion 7 during installation. As the screw moves along the lower portion 8, the gradually increasing height naturally creates a tilting tendency, thus facilitating tilted installation. This process reduces resistance during installation, improves installation efficiency, and lowers installation difficulty. Moreover, this gradually changing structure allows the screw to be subjected to more even force during tilting, avoiding screw damage or insecure installation due to uneven force. Furthermore, this connection method between the lower portion 8 and the higher portion 7 makes the force transmission more reasonable when the screw contacts the annular surface 6. When subjected to external force, the force can be evenly distributed to the entire base through the annular surface 6, reducing local stress concentration and further enhancing the overall stability of the base. At the same time, this gradient structure also allows the screw to better adapt to external forces in different directions after installation, improving the base's ability to resist external forces.

[0023] Furthermore, the screw limiting groove 9 is formed on the lower part 8 and extends along the edge of the inner hole 4 towards the higher part 7, so that a portion of the screw limiting groove 9 is formed on the higher part 7. Specifically, in this embodiment, extending the screw limiting groove 9 to the higher part 7 further enhances the limiting effect on the screw. When the screw is installed at an angle and contacts the annular surface 6, its screw portion falls into the screw limiting groove 9. Since the limiting groove extends to the higher part 7, the screw is effectively limited throughout the entire inclined installation path. This not only prevents the screw from shifting in the horizontal direction but also effectively suppresses shaking in the vertical direction. In actual use, wall switches and sockets may be affected by various external forces, such as the impact force when plugging and unplugging electrical appliances, and the external force of daily contact. This screw limiting groove 9 extending to the higher part 7 ensures that the screw maintains a stable installation state when facing these external forces and will not easily loosen. In addition, this design also facilitates positioning during the installation process. When inserting screws into mounting holes 2, installers can more easily locate the limiting groove and smoothly tilt and install the screws into place along the guide of the limiting groove. This improves installation accuracy and efficiency to some extent and reduces problems that may be caused by improper installation. At the same time, the screw limiting groove 9 extending to the upper part 7 also protects the annular surface 6 to some extent. When the screw engages with the limiting groove, it reduces direct wear on the annular surface 6, extending the service life of the base. Moreover, this design ensures that the base maintains good performance in different installation environments, guaranteeing stable installation and reliable use of the wall switch and socket base, whether in a humid environment or in a location with slight vibration.

[0024] Furthermore, the junction of the lower portion 8 and the higher portion 7 is located on one side of the center of the mounting hole 2. Specifically, in this embodiment, the junction of the lower portion 8 and the higher portion 7 is located on one side of the center of the mounting hole 2, making the force distribution of the screw on the annular surface 6 more asymmetrical. This asymmetrical force structure helps to further improve the stability of the base under complex external forces. When the wall switch socket is subjected to external forces from different directions, such as lateral tension or torsional force, this special force distribution allows the screw to cope better, making the base more firmly fixed on the carrier. In actual installation, due to differences in the operator's operation or local unevenness of the carrier surface, the initial installation position of the screw may deviate to some extent. However, the junction of the lower portion 8 and the higher portion 7 is off-center from the mounting hole 2, so that even if the installation position of the screw is slightly deviated, the height difference of the annular surface 6 can still be used to successfully achieve tilted installation, and good stability and firmness can still be maintained after installation. Moreover, this design can better disperse stress. Compared to the case where the junction of the lower part 8 and the higher part 7 is located at the center of the mounting hole 2, placing the junction on one side ensures that when the screw is subjected to external force,

[0025] Furthermore, the screw limiting groove 9 is wrench-shaped, and the opposite side walls of the screw limiting groove 9 are arc-shaped. Specifically, in this embodiment, this wrench-shaped design with arc-shaped side walls has many advantages. First, the wrench-shaped shape can better fit the shape of the screw head. When the screw is installed, its head can fall more accurately into the screw limiting groove 9, just like the fit of a key and a lock, further enhancing the limiting effect on the screw. This precise fit makes the screw more stable after installation, and less prone to shaking or displacement. Second, the arc-shaped groove wall design greatly reduces frictional resistance during installation. Compared with traditional right-angle groove walls, the arc-shaped groove wall does not obstruct the installation of the screw, and the installer can more easily push the screw along the limiting groove until it is installed in place. This not only improves the smoothness of installation, but also reduces the damage to the screw surface caused by excessive friction to a certain extent, extending the service life of the screw. Furthermore, when facing external forces, the arc-shaped groove wall can better disperse stress. When the wall switch socket is subjected to vibration or other external impacts, the force is evenly distributed across the entire base through the curved groove wall, avoiding localized stress concentration. This is similar to applying pressure to a circular object; the pressure is evenly distributed across the surface rather than concentrated at a single point. This stress dispersion effectively prevents damage to the base due to excessive localized stress, improving the overall durability of the base.

[0026] Furthermore, a disassembly / removal indicator 10 is provided on the portion of the base body 1 near the mounting hole 2, with one end of the indicator 10 pointing towards the mounting hole 2. Specifically, in this embodiment, the disassembly / removal indicator 10 provides clear and unambiguous guidance for personnel installing and disassembling the base. When the installer is operating, they can quickly and accurately locate the installation position by pointing to the mounting hole 2 with the indicator, without spending extra time searching and confirming, thus improving installation efficiency.
