DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 10As shown, the utility model discloses a modular wall switch, which includes a mounting portion 1, a base 2 and a cover plate 3 from the back to the front. The cover plate 3 is rotatably mounted on the base 2, and the projection of the mounting portion 1 toward the front side falls on the base 2. Since the cover plate 3 is rotatably mounted on the base 2, the circuit can be connected and disconnected by applying force to the cover plate 3 on the front side (this is the prior art and will not be elaborated on here). The cover plate 3 includes a front connecting section 31, a matching section 32 and a rear connecting section 33. The matching section 32 is located between the front connecting section 31 and the rear connecting section 33. The front side of the base 2 is provided with a mounting groove 21 for the matching section 32 and the rear connecting section 33 to be installed. The base 2 is located in the mounting groove 2 1 is fixedly installed with the limited segment 22 by welding or the like, the inner wall of the limited segment 22 abuts against the circumference of the front connecting segment 31, the width of the matching segment 32 is greater than the width of the limited segment 22, the matching segment 32 and the limited segment 22 are both made of rubber or other materials that are easy to deform, the front side end face of the matching segment 32 abuts against the rear side end face of the limited segment 22, the base 2 is detachably connected to the mounting portion 1 by means of buckles, bolts, etc., and the base 2 is detachably connected to the cover plate 3 by means of buckles, bolts, etc., 1. Since the base 2 is located between the mounting portion 1 and the cover plate 3, and the base 2 is detachably connected to the mounting portion 1 and the cover plate 3, the three are connected after they are connected. The assembly of the wall switch can be completed, thereby facilitating the assembly of the wall switch; 2. When the rear side of the cover plate 3 enters the installation groove 21, at this time, since the base 2 is located on the installation groove 21 and the limiting section 22 is fixedly installed, and the width of the matching section 32 of the cover plate 3 is greater than the width of the limiting section 22, and the matching section 32 and the limiting section 22 are both made of materials that are easy to deform, when the matching section 32 of the cover plate 3 enters the installation groove 21, the matching section 32 needs to squeeze the limiting section 22 and then forcibly cross the limiting section 22 so that the matching section 32 is located at the rear side of the limiting section 22 to achieve that the front side end face of the matching section 32 and the rear side end face of the limiting section 22 are against each other, so if external dust and moisture pass through the cover plate 3 When dust and moisture enter the gap between the cover plate 3 and the base 2, dust and moisture can first contact the limiting section 22 and the matching section 32 located at the rear side of the limiting section 22 before entering the installation groove 21, and the width of the matching section 32 is greater than the limiting section 22. Therefore, dust and moisture entering the wall switch cannot pass through the matching section 32 and enter the installation groove 21 and enter the rear side of the cover plate 3 to contact the installation part 1 and the base 2. At the same time, the matching section 32 and the limiting section 22 can make the cover plate 3 stably located on the front side of the base 2 without separating from the base 2. Therefore, the setting of the matching section 32 and the limiting section 22 can effectively isolate the dust, moisture and other substances from the outside from entering the wall switch, thereby extending the service life of the wall switch.

[0028] Preferably, the rear side of the mating section 32 includes a mating surface 321, and the mating surface 321 is inclined from top to bottom and from back to front. When the mating section 32 is squeezed and forced to pass through the limiting section 22 and be located in the mounting groove 21 of the base 2, 1. Since the mating surface 321 is inclined, the interior of the mating section 32 is an empty groove, and the cross-section of the mating section 32 gradually widens from back to front. Therefore, the narrowest part of the mating section 32 first contacts the limiting section 22 and can be deformed toward the empty groove inside, so that the mating section 32 can more smoothly pass through the limiting section 22 and be located in the mounting groove 21; 2. Since the position of the mating section 32 at the rear side of the limiting section 22 is the part with the largest width, when external dust passes through the limiting section 22, the dust will first contact the part with the largest width of the mating section 32. Therefore, the mating section 32 can jointly achieve a double sealing and blocking effect with the limiting section 22, thereby further blocking external dust and moisture.

[0029] In addition, the mounting portion 1 includes a buckle section 23111 and a mounting seat 12, and the buckle section 23111 and the mounting seat 12 are detachably connected by buckles or other means, and the buckle section 23111 is provided with a plurality of buckle seats 111 protruding upward, and a plurality of mounting plug-in blocks 311 are protruding downward on the front connecting section 31, and each of the buckle seats 111 is provided with a mounting slot 1111 for the corresponding mounting plug-in block 311 to be inserted, and each of the buckle seats 111 includes a buckle plug-in block 1112 on the left side that abuts against the corresponding mounting plug-in block 311, because each mounting plug-in block on the front connecting section 31 311 can be inserted into the installation slot 1111 on each snap seat 111 on the snap section 23111, and the positioning block 126 of each snap seat 111 is abutted against the corresponding installation block 311. Therefore, after the lower connecting section and the matching section 32 of the cover plate 3 are installed into the base 2, the cover plate 3 located on the base 2 can not only be stably located in the base 2, but also the installation blocks 311 on the cover plate 3 can prevent the cover plate 3 from moving and shaking relative to the snap section 23111, that is, relative to the installation part 1, thereby further enabling the various components of the wall switch to be stably connected together.

[0030] In fact, the upper and lower sides of the rear side of the buckle section 23111 are provided with rear abutment blocks 112, and the mounting seat 12 is provided with abutment grooves 121 for each rear abutment block 112 to be inserted into. The upper and lower sides of the mounting seat 12 located at the abutment grooves 121 are provided with front abutment blocks 122 inserted with the corresponding rear abutment blocks 112. During the assembly process of the buckle section 23111 and the mounting seat 12, after each rear abutment block falls into the abutment groove 121, Each rear abutment plug block 112 can abut against each front abutment plug block 122, that is, the setting of each front abutment plug block 122 can make the upper and lower ends of each rear abutment plug block 112 respectively limited by the corresponding front abutment plug block 122 so that the buckle section 23111 cannot move in the up and down directions relative to the mounting seat 12, so the buckle section 23111 cannot shake relative to the mounting seat 12, so that the buckle section 23111 can be stably connected to the mounting seat 12.

[0031] Among them, each of the rear abutment plug blocks 112 is protrudingly provided with a lower abutment plug block 4, the mounting seat 12 is located on each front abutment plug block 122 and is provided with a front abutment slot 123 for the corresponding rear abutment plug block 112 to be inserted, the mounting seat 12 is located above each front abutment slot 123 and is provided with an upper abutment plug block 124, and each lower abutment plug block 4 is provided with a lower abutment slot 41 for the corresponding upper abutment plug block 124 to be inserted, because the lower abutment plug block 4 on each rear abutment plug block 112 needs to be forcibly squeezed to pass over the corresponding upper abutment plug block 124 when entering the corresponding front abutment slot 123, so that each The lower contact block 4 enters the corresponding front contact groove 121. At this time, each upper contact block 124 is respectively located in each lower contact slot 41 on the corresponding lower contact block 4, thereby further enabling the buckle section 23111 to be stably connected to the mounting seat 12. Specifically, each lower contact block 4 of the buckle section 23111 cannot pass over the corresponding upper contact block 124 without the action of external force. Therefore, the buckle section 23111 and the mounting seat 12 after assembly cannot be shaken and separated in the front and rear directions, further improving the stability of the connection between the buckle section 23111 and the mounting seat 12.

[0032] Preferably, each of the lower contact blocks 4 includes a guide surface 42, and each guide surface 42 is inclined from bottom to top from front to back. After each lower contact block 4 squeezes the corresponding upper contact block 124, since each guide surface 42 is inclined from bottom to top from front to back, each lower contact block 4 is set in a shape that is narrow at the back and wide at the front. The first part that squeezes the corresponding upper contact block 124 is the narrowest part of each lower contact block 4. Therefore, the rear side of each lower contact block 4 can be deformed inward more smoothly and then pass over the corresponding upper contact block 124 and enter the corresponding front contact slot 123.

[0033] The base 2 is provided with a plurality of connection blocks 23 protruding downward, each of the connection blocks 23 is provided with a plurality of buckle sections 23111 at intervals from top to bottom, each of the connection blocks 23 is provided with a buckle groove 232 between adjacent buckle sections 23111, the mounting seat 12 is provided with a connection slot 125 corresponding to each connection block 23, the mounting seat 12 is provided with a positioning block 126 protruding in each connection slot 125, each positioning block 126 is abutted against the corresponding connection block 23, the mounting seat 12 is provided with an upper limit block 127 on the inner side of each connection slot 125, and the rear connection section 33 is provided with a lower limit block 331 above each upper limit block 127, 1. 1. The setting of the upper limit plug block 127 and the lower limit plug block 331 enables the two to limit the relative position of the base 2 and the mounting seat 12, that is, the base 2 cannot move toward the mounting seat 12 blindly and cause the upper and lower limit plug blocks 331 to collide; 2. Due to the existence of the upper limit plug block 127 and the lower limit plug block 331, the relative position of the mounting seat 12 and the base 2 can be limited, thereby determining which part of the buckle section 23111 that cooperates with the connecting slot 125 is, thereby achieving the buckle section 23111 passing over the positioning plug block 126 and achieving the positioning plug block 126 to fall into the corresponding buckle groove 232, thereby enabling the base 2 to be stably connected to the mounting seat 12.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be 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 will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
