Description

Technical Field

[0001] This utility model relates to the field of wall switch technology, and more specifically to a protective structure for a wall switch. Background Technology

[0002] Currently, a wall switch refers to an electrical device installed on a wall, an electronic component used to open a circuit, interrupt current, or divert it to another circuit. With the continuous improvement of people's living standards and the increasing diversification and complexity of electrical equipment, people's demand for wall switches is also constantly increasing. Existing wall switches usually include a mounting bracket, a junction box, and internal functional modules. The junction box is installed in the wall, and the internal functional modules are set on the base and then fixed to the base box by the mounting bracket. A panel is usually also set on the mounting bracket. Depending on the internal functional components and the panel, they can be divided into plugs or switches.

[0003] However, there are still some defects in the above-mentioned existing technologies. Adjustments to some processes during production and processing can affect the production environment. In certain production environments or usage scenarios (such as dust, humidity, oil, etc.), protective housings are required to ensure the normal operation of wall switches. However, some wall switches were not designed with the harsh environment in mind. In such cases, it is often necessary to replace the entire switch device to ensure normal operation, which is very inconvenient. Utility Model Content

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] This embodiment discloses a protective structure for a wall switch, such as Figures 1 to 3As shown, the device includes a switch body 1, an outer ring base 2, and a protective cover 4 movably connected to the outer ring base 2. The outer ring base 2 is fitted onto the switch body 1 and has a quick-release structure 3 for detachably fixing it to the switch body 1. The quick-release structure 3 enables quick connection / separation of the outer ring base 2 from the switch body 1, simplifying the installation and disassembly process without tools or screws, making it very convenient. The protective cover 4 can rotate relative to the outer ring base 2 to cover or expose the front area of ​​the outer ring base 2, providing a physical shielding layer to protect the switch panel. The rotating design allows users to easily expose the switch button for operation when needed, and cover the switch button when not in use or when protection is required. The quick-release structure 3 includes a pressure plate 31 with retractable teeth 311 on both sides. Symmetrically arranged on the side of the pressure plate 31 facing the switch body 1 are pressure blocks 33 with inclined surfaces A331. The inclined surface A331 enables stable clamping and self-positioning of both sides of the switch body 1; the pressure block 33 is made of rubber, which generates greater static friction and provides a good anti-slip fixing effect. Moreover, rubber is a soft material and will not scratch or wear the switch surface during the pressing process; the side wall of the outer ring base 2 is provided with continuous tooth grooves 21 that are adapted to the locking teeth 311. Mechanical locking is achieved through the meshing of the locking teeth 311 and the tooth grooves 21, providing a firm and reliable snap-fit ​​connection and ensuring that the outer ring base 2 is stably fixed on the switch body 1.

[0018] like Figure 2 As shown, a stop protrusion 312 is provided on the inner end of the locking tooth 311; a spring B is sleeved on the locking tooth 311 to retract it, and the spring B abuts against the stop protrusion 312; the quick-release structure 3 also includes a stop block 314, which abuts against the stop protrusion 312. The stop block 314 abuts against the stop protrusion 312 to limit the retraction of the locking tooth 311 and maintain a stable extended state.

[0019] like Figure 3 As shown, the stop block 314 has an inclined surface C3141 near its lower end; the stop protrusion 312 has an inclined surface B3121 near its upper end, which is adapted to the inclined surface C3141; when the stop block 314 is reset, it can push the retaining tooth 311 out through the contact of the inclined surface B3121 with the inclined surface C3141. The upper end of the stop block 314 is provided with a spring B3142 for resetting it. The stop block 314 is provided with a spring cavity for placing the spring B3142, and the inner wall of the pressure plate 31 is also provided with a spring protrusion for assisting in the positioning and installation of the spring B3142.

[0020] Further improvements include an opening and a pushing protrusion 3143 / 34 near the stop block 314 on the pressure plate 31; the stop block 314 is provided with a pushing protrusion 3143 adapted to the opening 34, and the pushing protrusion 3143 provides a force application point for operating the stop block 314. The user can directly contact and operate the pushing protrusion 3143 through the opening 34 to unlock the quick-release structure, making the operation intuitive and convenient.

[0021] Further improvements include a horizontal bottom surface for the locking tooth 311, which fits tightly against the bottom plane of the tooth groove 21, providing stable support and resistance to pull-out, and enhancing locking strength; an inclined surface is provided on its upper end surface, which makes it easier for the inclined surface of the locking tooth 311 to slide into the tooth groove 21 when it extends out and engages with the tooth groove 21, facilitating guidance and engagement.

[0022] Furthermore, an insertion rod 32 is provided below the pressure plate 31; the outer ring base 2 is correspondingly provided with a cavity 22 to accommodate the insertion rod 32. The insertion rod 32, when inserted into the cavity 22, provides additional positioning and guidance, ensuring that the pressure plate 31 is accurately positioned relative to the outer ring base 2, avoiding misalignment, preventing the pressure plate 31 from shaking or shifting during use (such as when pressing a switch), and improving the overall structural rigidity and operational stability.

[0023] Working principle of this utility model

[0024] During installation, place the outer ring base 2 onto the switch body 1 and align it. Push the pushing protrusion 3143 to move the stop block 314 downward, releasing the block 314 from obstructing the stop protrusion 312. The retaining tooth 311 will retract under the action of the spring A313. At this time, push the pressure plate 31 closer to the switch body 1, causing the pressure block 33 to press against the switch body 1. Release the pushing protrusion 3143, and the stop block 314 will reset under the action of the spring B3142. Its inclined surface C3141 will contact the inclined surface B3121 of the stop protrusion 312, thereby pushing the stop protrusion 312 to extend the retaining tooth 311 and engage with the tooth groove 21. The installation can be completed simply and conveniently.

[0025] During disassembly, pushing the protrusion 3143 releases the obstruction of the pressure block 33 on the stop protrusion 312. The retaining tooth 311 retracts under the action of the spring A313, and the pressure plate 31 can be easily moved down, releasing the fixation between the switch body 1 and the outer ring base 2. The outer ring base 2 can then be easily removed.

[0026] 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 design concept of the present utility model should be included within the protection scope of the present utility model.
