Description

Technical Field

[0001] The utility model relates to a switch, specifically a wall switch. Background Art

[0002] A wall switch generally consists of a base, a panel, and a button. The panel mainly serves a decorative function. The base houses a switch switching component, and the button cooperates with the switch switching component to achieve interaction and then perform the on-off switching of the circuit.

[0003] The patent document "Double-motor type bathroom heater switch" (CN216562891U) discloses an assembly solution of a wall switch in the prior art, revealing that the base generally consists of a bottom shell and a cover plate. The cover plate is installed on the bottom shell. The cover plate has a stud, and the bottom shell houses a switch switching component. The stud cooperates with the switch switching component to perform on-off switching. Generally, the cover plate is installed on the bottom shell by a snap-fit method, and the panel is also snap-fitted and assembled with the bottom shell.

[0004] Currently, the existing snap-fit method has insufficient installation strength and is prone to snap-fit loosening after long-term use, which will affect the user experience after loosening. Therefore, a wall switch structure with better installation strength is still needed. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a wall switch that can have higher installation strength and is not prone to loosening after long-term use.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A wall switch includes a bottom shell for accommodating a switch switching component, a cover plate installed on the bottom shell. The bottom shell and the cover plate are snap-fitted through a plurality of snap fasteners. It further includes: a frame having an opening for installing the bottom shell; an outer frame for installing on the cover plate and abutting against the bottom shell; a snap-fastening member provided on the outer frame and snap-fastened with the edge of the frame, and a supporting member provided on the frame for supporting the bottom shell; the edge of the frame corresponding to the snap-fastening member provides a first acting force for the snap-fastening member towards the supporting member, and the supporting member provides a second acting force for the bottom shell towards the snap-fastening member; after the bottom shell and the cover plate are snap-fitted, they are kept in a tight fit through the first acting force and the second acting force.

[0008] As a further improvement of the present utility model, a protrusion extending towards the outer frame is provided on the supporting member, and a positioning groove for embedding the protrusion is provided at the position where the bottom shell is supported in cooperation with the supporting member.

[0009] As a further improvement of the present utility model, a baffle is provided on the frame at a position corresponding to the buckle between the bottom shell and the cover plate, and the support member is located on the baffle. When the bottom shell is connected to the support member, the buckle is restricted from deforming by the baffle.

[0010] As a further improvement of the present utility model, a protrusion extending towards the outer frame is provided on the support member, and a positioning groove for the protrusion to be embedded is provided at a position where the bottom shell is supported in cooperation with the support member.

[0011] As a further improvement of the present utility model, a card slot is provided on the side surface of the cover plate, and a card block is provided on the outer frame at a position corresponding to the card slot; a chamfer is provided at the transition between the front surface and the side surface of the cover plate and at a position corresponding to the card slot, and the deformability of the cover plate is increased through the chamfer at a position corresponding to the card slot on the side surface of the cover plate.

[0026] The present utility model will be further described in detail below with reference to the embodiments shown in the drawings.

[0027] Referring to Figures 1-9 shown, a wall switch in this embodiment includes a bottom shell 1 for accommodating a switch switching component, a cover plate 2 installed on the bottom shell 1, and the bottom shell 1 and the cover plate 2 are clamped by a plurality of buckles 3. It further includes

[0028] a frame 4 having an opening for installing the bottom shell 1;

[0029] an outer frame 5 for installing on the cover plate 2 and abutting against the bottom shell 1;

[0030] a clamping member 51 is provided on the outer frame 5, and the clamping member 51 is clamped with the edge of the frame 4. A support member 41 for supporting the bottom shell 1 is provided on the frame 4;

[0031] The edge of the frame 4 corresponding to the clamping member 51 provides a first acting force of the clamping member 51 towards the support member 41, and the support member 41 provides a second acting force of the bottom shell towards the clamping member 51; after the bottom shell 1 and the cover plate 2 are clamped, they are kept in a tight fit by the first acting force and the second acting force.

[0032] Combined with Figure 1 and 2 shown, after the bottom shell 1 and the cover plate 2 are preliminarily connected by the buckle 3, the clamping member 51 of the outer frame 5 is engaged with the edge of the frame 4, and the support member 41 of the frame 4 exerts a reverse acting force on the bottom shell 1 to form a two-way clamping.

[0033] This design eliminates the clamping gap through the two-way acting force, makes the connection between the bottom shell 1 and the cover plate 2 tighter, and avoids the loosening problem caused by uneven unilateral force after long-term use.

[0034] In this solution, the strength of the frame 4 can be increased, and at this time, the stability of the installation strength can be further ensured. Moreover, only the strength of the frame 4 needs to be improved, so the cost increase is not obvious.

[0035] An installation panel can be arranged outside the frame 4, and decoration can be carried out through the panel.

[0036] As an implementation manner that can make the frame 4 and the bottom case 1 fit more stably, a protrusion 411 extending towards the outer frame 5 is arranged on the support member 41, and a positioning groove 11 for the protrusion 411 to be embedded is arranged at the position of the bottom case 1 where the support member 41 is supported. After the protrusion 411 is embedded in the positioning groove 11, the lateral displacement of the bottom case 1 on the support member 41 is restricted, and the positioning accuracy is enhanced.

[0037] Based on the cooperation between the protrusion 411 and the positioning groove 11 described above, in an optional solution, a baffle 42 is arranged on the frame 4 at the position corresponding to the buckle 3 between the bottom case 1 and the cover plate 2, and the support member 41 is located on the baffle 42. When the bottom case 1 is connected to the support member 41, the buckle 3 is restricted from deforming through the baffle 42. The baffle 42 provides a constraint on the deformation direction of the buckle 3, preventing the buckle 3 from being overly bent and disengaged or broken due to external force. The integrated design of the support member 41 and the baffle 42 enhances the local strength of the frame 4, enabling the buckle 3 to maintain a stable clamping force during long-term use.

[0038] Of course, the solution of the baffle 42 can also be implemented without the cooperation between the protrusion 411 and the positioning groove 11.

[0039] In order to make the cooperation relationship between the cover plate 2 and the outer frame 5 more stable, in an optional solution, a card slot 21 is arranged on the side surface of the cover plate 2, and a card block 52 is arranged on the outer frame 5 at the position corresponding to the card slot 21; a chamfer 22 is arranged at the transition between the front surface and the side surface of the cover plate 2 and at the position corresponding to the card slot 21, and the chamfer 22 increases the deformability of the side surface of the cover plate 2 at the position corresponding to the card slot 21.

[0040] The design of the chamfer 22 makes the side surface of the cover plate 2 more likely to generate elastic deformation when the card block 52 is embedded in the card slot 21 (which can weaken the strength of the cover plate 2 at the position corresponding to the chamfer 22 and facilitate deformation for clamping), reducing the assembly resistance. The cooperation between the card block 52 and the card slot 21 realizes flexible locking through the guiding action of the chamfer 22, avoiding the risk of fracture caused by hard assembly.

[0041] In a preferred solution, the frame 4 is made of a metal material. The metal frame 4 provides higher structural strength and anti-deformation ability, and when the metal frame 4 is installed with the junction box, it can provide stronger strength, better installation stability, and is not easily deformed.

[0042] To improve safety, the frame 4 extends to the side of the bottom shell 1 and is threadedly connected by bolts 6; the bolts 6 are connected to the ground wire to ground the frame 4. The bolts 6 can be used to cooperate with the frame 4 to clamp the ground wire and ground the frame 4, thereby enhancing safety.

[0043] In addition, the following preferred improvement solutions can be made. The position on the frame 4 for cooperating with the bolts 6 also cooperates with the corresponding buckle 3 at the corresponding position to limit the deformation of the buckle 3. Since this position needs to extend and install the bolts 6, using this position to cooperate with the buckle 3 at the same time can limit the deformation of the buckle 3, making the snap connection between the bottom shell 1 and the cover plate 2 more stable.

[0044] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as within the protection scope of the present invention.
