Technical Field

[0001] The utility model relates to the field of wiring bottom boxes, in particular to a wall switch wiring bottom box. Background Art

[0002] A junction box is an essential electrical tool used in construction and renovation projects. It connects electrical wires, ensures the transition between electrical circuits, and protects the circuits. Traditional switches and sockets are mounted into the wall via a junction box. This involves first installing the junction box into the wall, and then securing the junction box and cover plate with screws inserted into the cover plate and nuts inside the junction box.

[0003] Chinese patent application publication number CN216121672U, publication date March 22, 2022, titled "A Junction Box", discloses a junction box, which includes an installation box body, an anti-slip nut movably provided in the installation box body, and a serration provided on the anti-slip nut; a flip cover is hingedly provided at the bottom end of the installation box body, a buckle rib is provided on the flip cover, and a buckle used in conjunction with the buckle rib is provided on the installation box body, which not only prevents the nut from idling in the installation hole of the junction box, but also forms the anti-mud and sand cover and the junction box into a whole, which is convenient for production and effectively reduces costs.

[0004] However, the junction box needs to be flipped over to close the butt opening when it is installed and used, which increases the steps required for assembling the junction box, extends the time required for assembly, and reduces the work efficiency of assembly. Therefore, there is room for improvement. Utility Model Content

[0005] In order to overcome the disadvantage of low assembly efficiency of a wiring base box in the prior art, the utility model provides a wall switch wiring base box, which simplifies the assembly process of the wiring base box and improves the assembly work efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wall switch wiring base box includes a box body and side panels arranged on the box body, the box body and the side panels are detachably connected, the inner side wall of the box body is provided with an integrally injection-molded bearing ear, the bearing ear is provided with a receiving cavity for accommodating a nut, the bottom wall of the box body is provided with a mating opening for a mold to pass through and corresponding to the receiving cavity, the side panels are provided with a bottom plate, and when the box body is connected to the side panels, the bottom plate covers the mating opening.

[0008] In the above technical solution, the box body and the ear are integrally molded by providing a butt joint. When the junction box needs to be assembled, the nut is installed in the ear, and then the side panel and the box body are connected. At the same time, the bottom plate on the side panel shields the butt joint, thereby simultaneously achieving the installation of the side panel and the closure of the butt joint. By integrating the side panel and the bottom plate, the bottom plate closes the butt joint while the side panel is installed. There is no need to adopt another process to close the butt joint. The assembly process of the junction box is simplified, the time required for assembly is shortened, and the work efficiency of assembly is improved. At the same time, since the bottom plate is installed on the side plate, the connection between the bottom plate and the box body is also achieved while the connection between the side panel and the box body is achieved. There is no need to adopt another structure to achieve the connection between the bottom plate and the box body, which reduces the required parts and reduces the assembly cost of the junction box.

[0009] Preferably, the bearing ear is provided with through-holes on the cavity walls on both sides opposite to the accommodating cavity, the through-holes are connected to the accommodating cavity and correspond to the collision port, the aperture of the through-holes is smaller than the outer diameter of the nut, the side wall of the box body is provided with a mounting hole connected to the accommodating cavity, the nut is installed in the accommodating cavity through the mounting hole, and the side panel is provided with a blocking plate, and when the box body is connected to the side panel, the blocking plate blocks the orifice of the mounting hole. Through the above technical solution, when the nut needs to be installed on the box body, the nut is placed in the accommodating cavity through the orifice of the mounting hole, and then the box body is connected to the side panel, and the blocking plate blocks the orifice of the mounting hole, thereby preventing the nut from falling out of the orifice of the mounting hole, and preventing mud and sand from entering the accommodating cavity through the mounting hole during installation and affecting the use of the nut, thereby reducing the risk of nut failure in the junction box body affecting the subsequent assembly between the box body and the cover plate, and improving the stability of the use of the junction box body. When the cover plate needs to be installed on the box body, the screws on the cover plate are threaded into the perforations, and then threaded into the corresponding nuts through the perforations, thereby connecting the cover plate and the box body. The side panels and the box body are detachably connected. Therefore, if the nuts fail and need to be replaced, the connection between the side panels and the box body can be simply disconnected, that is, the blocking plate no longer blocks the opening of the mounting hole. The nuts can then be removed from the receiving cavity through the opening of the mounting hole without replacing the entire box body, reducing waste during the assembly process and lowering the assembly cost of the junction box.

[0010] Preferably, an upper buckle groove is provided on the hole wall of the mounting hole, and the blocking plate is provided with an upper buckle block that is buckled and matched with the upper buckle groove.

[0011] Through the above technical solution, when the side panel is installed on the box body, the blocking plate is inserted into the mounting hole so that the blocking plate blocks the opening of the mounting hole. During the blocking plate insertion process, the wall of the mounting hole applies pressure to the upper buckle block, which is made of elastic material. The upper buckle block is elastically deformed under force and maintains a tendency to reset. When the blocking plate is inserted, the upper buckle block on the blocking plate moves to the opening of the upper buckle groove. The wall of the mounting hole no longer applies pressure to the upper buckle block, and the upper buckle block resets and engages with the upper buckle groove, thereby further strengthening the connection between the blocking plate and the box body, improving the blocking effect of the blocking plate on the opening of the mounting hole, reducing the risk of mud and sand entering the accommodating cavity through the mounting hole during installation and affecting the subsequent installation of the junction box, and improving the stability of the junction box.

[0012] Preferably, the side wall of the box body is provided with a plug-in hole, and the side panel is provided with a mud and sand baffle that is plugged into the plug-in hole. When the box body is connected to the side panel, the mud and sand baffle covers one end of the through-hole and is located on the side of the supporting ear away from the collision port.

[0013] Through the above technical solution, in the process of installing the side panel on the box body, the mud and sand baffle is plugged into the plug hole, so that the mud and sand baffle enters the box body through the plug hole, and when the box body is connected to the side panel, the mud and sand baffle covers one end of the perforation and is located on the side of the bearing ear away from the collision port, thereby preventing mud and sand from entering the accommodating cavity through the upper end of the perforation during the installation of the junction box body, reducing the risk of mud and sand entering the accommodating cavity and affecting the use of the nut, and improving the stability of the junction base box.

[0014] Preferably, the side plate is connected to the sediment baffle via a breaking portion, and the breaking portion is easy to break.

[0015] Through the above technical solution, a breaking portion that is easy to break is adopted. When the box body and the cover plate need to be connected, the screw on the cover plate needs to be threaded into the through-hole and threaded with the corresponding nut. Therefore, the mud and sand baffle needs to no longer cover the upper end opening of the through-hole. The side plate and the mud and sand baffle are connected by the breaking portion. The breaking plate is easy to break. Therefore, it is only necessary to apply external force to the breaking portion to break the breaking portion, thereby canceling the connection between the side plate and the mud and sand baffle, so that the mud and sand baffle no longer covers the through-hole opening. The operation is simple and convenient, which improves the convenience of using the junction box.

[0016] Preferably, a plurality of side buckle plates are provided on both sides of the side panel, and a plurality of side buckle holes corresponding to the side buckle plates are opened on the side wall of the box body, and the side buckle plates are plugged into the corresponding side buckle holes, and the side buckle plates are provided with side buckle blocks that abut against the inner wall of the box body.

[0017] When the side panel is installed on the box body, the side buckle plate on the side panel is plugged into the side buckle hole, and the side buckle block is installed on the side buckle plate. The side buckle block is made of elastic material. In the process of inserting the side buckle plate into the corresponding side buckle hole, the hole wall of the side buckle hole exerts pressure on the side buckle block. The side buckle block is elastically deformed under the force and maintains a tendency to reset. When the side panel and the box body are installed, the side buckle block moves out of the side buckle hole, and the hole wall of the side buckle hole no longer exerts pressure on the side buckle block. The side buckle block is reset, and the side of the side buckle block close to the inner wall of the box body abuts against the inner wall of the box body, thereby limiting the movement of the side panel in the direction away from the box body, that is, realizing the installation between the side panel and the box body. The operation is simple and quick, convenient for the assembly of the wiring base box, shortening the time required for the assembly of the wiring base box, and improving the assembly efficiency of the wiring base box.

[0018] Preferably, the inner wall of the box body is provided with two vertical ribs, and the side buckle blocks are in abutment with the corresponding vertical ribs.

[0019] Through the above technical solution, when the side buckle block moves out of the side buckle hole, the side buckle block is reset. During this process, the side of the side buckle block close to the inner wall of the box body will abut and cooperate with the corresponding vertical rib, thereby enhancing the connection strength between the side panel and the box body, reducing the risk of accidental detachment of the side panel and affecting the use of the junction box, and improving the stability of the junction box.

[0020] Preferably, the side wall of the box body is provided with a penetration groove corresponding to the collision opening. When the box body is connected to the side plate, the bottom plate passes through the penetration groove and is located on the side of the collision opening close to the inner wall of the box body.

[0021] Through the above technical solution, when the side panel is installed on the box body, the bottom plate passes through the insertion groove and covers the collision port to prevent mud and sand from entering the box body through the collision port. The bottom plate is located inside the box body, which reduces the risk of deformation or even damage of the bottom plate due to external force during the installation of the wiring base box, ensures the stability of the bottom plate covering the collision port, and improves the stability of the wiring base box.

[0022] Preferably, the inner wall of the box body is provided with two screw baffles, and the two screw baffles are respectively provided on both sides of the bearing ear.

[0023] Through the above technical solution, when the box body and the cover are installed, the screws on the cover pass through the holes from top to bottom, and the screw baffle can effectively wrap the screws to prevent the screws from scratching the wires, thereby improving the stability of the junction box.

[0024] Preferably, the box body is provided with an alignment component for serving as a horizontal alignment reference.

[0025] Through the above technical solution, when the staff installs the junction box on the wall, the junction box and the wall will be horizontally aligned. The staff usually uses an infrared level or a heavy plumb line, and the alignment component can be used as a flush reference. The staff can adjust the installation position of the junction box through the alignment component, reducing the risk of the junction box being installed crookedly and improving the installation quality of the junction box.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The simplified assembly process of the junction box shortens the assembly time and improves the assembly efficiency;

[0028] 2. It reduces the number of parts required and the waste in the assembly process, thus reducing the assembly cost of the junction box;

[0029] 3. Reduces the risk of mud and sand entering the accommodation cavity and affecting subsequent installation, and improves the stability of the junction box;

[0030] 4. The risk of the junction box being installed at a crooked position is reduced, and the installation quality of the junction box is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] Embodiment 1:

[0043] Example 1 of the present application discloses a wall switch wiring base box.

[0044] Reference Figure 1 A wall switch wiring base box includes a box body 1 and two side panels 2 installed on the box body 1. The box body 1 and the side panels 2 are detachably connected, and the two side panels 2 are respectively located on the outer walls of the box body 1 on both sides away from each other.

[0045] Reference Figure 1 and Figure 2 The inner wall of the box body 1 is provided with two integrally-injected bearing ears 3, and the bearing ears 3 are provided with a receiving cavity 31 for accommodating a nut. The bottom wall of the box body 1 is provided with two mating openings 11 for the mold to pass through and corresponding to the receiving cavity 31. The side panels 2 are integrally formed with the bottom panel 21, and the side panels 2 and the bottom panel 21 are arranged vertically. The side walls of the box body 1 are provided with two insertion grooves 12 corresponding to the mating openings 11, and the bottom panel 21 is plugged into the corresponding insertion grooves 12. When the box body 1 is connected to the side panels 2, the bottom panel 21 passes through the insertion grooves 12 and covers the mating opening 11, and is located on the side of the mating opening 11 close to the inner wall of the box body 1.

[0046] Reference Figure 2 and Figure 3 The ear 3 is provided with a through hole 32 located on the opposite side walls of the accommodating cavity 31. The through hole 32 is connected to the accommodating cavity 31 and corresponds to the butt port 11. The aperture of the through hole 32 is smaller than the outer diameter of the nut.

[0047] Reference Figure 2 and Figure 3 The side wall of the box body 1 is provided with a mounting hole 13 connected to the accommodating cavity 31, and the nut is installed into the accommodating cavity 31 through the mounting hole 13. The side plate 2 is fixedly connected with a blocking plate 22. When the box body 1 and the side plate 2 are connected, the blocking plate 22 blocks the opening of the mounting hole 13.

[0048] Reference Figure 4 A plurality of side buckle plates 24 are fixedly connected to both sides of the side panel 2, and a plurality of side buckle holes 15 corresponding to the side buckle plates 24 are opened on the side wall of the box body 1, and the side buckle plates 24 are plugged into the corresponding side buckle holes 15.

[0049] Reference Figure 4 The inner sidewall of the box body 1 is fixedly connected to two groups of vertical ribs 16 corresponding one to each of the lugs 3. Each group of vertical ribs 16 consists of two vertical ribs, and the two vertical ribs 16 in the same group are located on either side of the corresponding lug 3. A side buckle block 241 is fixedly connected to the side of the side plate 24 away from the side plate 2, and abuts against the vertical ribs 16. The side buckle block 241 is made of an elastic material such as plastic or rubber, and is arranged at an angle on the side away from the side buckle block 24. When the box body 1 is connected to the side plate 2, the side of the side buckle block 241 near the inner wall of the box body 1 abuts against the vertical rib 16.

[0050] Reference Figure 4 The inner wall of the box body 1 is fixedly connected with two groups of screw baffles 17 corresponding to the bearing ears 3 one by one, each group of screw baffles 17 has two, and the two screw baffles 17 in the same group are respectively located on both sides of the corresponding bearing ears 3.

[0051] Reference Figure 5 The bottom wall of the box body 1 is integrally formed with two mounting plates 18. The two mounting plates 18 are located on opposite sides of the box body 1 and are both provided with notches 181. The two notches 181 are arranged in a staggered manner. The mounting plate 18 is integrally formed with a fixing plate 183 that can be plugged into the corresponding notches 181.

[0052] Reference Figure 5 One side of the mounting plate 18 is fixedly connected to a snap-in plate 182 corresponding to the notch 181 , and the side of the snap-in plate 182 close to the notch 181 is fixedly connected to a locking block 1821 , and the fixing plate 183 is provided with a locking groove 1831 that can be plugged into and cooperate with the locking block 1821 .

[0053] Reference Figure 5, the locking block 1821 is made of elastic materials such as plastic and rubber. When the box body 1 needs to be connected to another box body 1, the side of the box body 1 installed with the mounting plate 18 is connected to the side of the other box body 1 installed with the mounting plate 18. Since the notches 181 on the mounting plates 18 on both sides of the box body 1 are staggered, the notches 181 of the box body 1 will face the fixing plates 183 on the other box body 1, and the fixing plates 183 on the box body 1 will face the notches 181 on the other box body 1. Then, the fixing plates 183 are plugged into the corresponding notches 181. During the plugging and matching process, the fixing plates 183 will lock the lock. The fixed block 1821 applies pressure, and the locking block 1821 is elastically deformed under the force. When the fixing plate 183 is plugged into the corresponding notch 181, the locking groove 1831 on the fixing plate 183 is opposite to the locking block 1821, and the fixing plate 183 no longer applies force to the locking block 1821. The locking block 1821 is reset and plugged into the corresponding locking groove 1831, thereby realizing the splicing of the two box bodies 1, so that the junction box can be adapted to different usage requirements, thereby improving the practicality of the junction box, and the splicing operation of the two box bodies 1 is simple and quick, thereby improving the convenience of using the junction box.

[0054] Reference Figure 5 The side wall of the box body 1 is provided with a plurality of knock-out grooves 6, so as to facilitate forming a through hole on the side wall of the box body 1 for the wires to pass through.

[0055] The implementation principle of a wall switch wiring base box in Example 1 of the present application is as follows:

[0056] The ears 3 on the junction box are used to place the nuts required for connecting the junction box to the cover plate. In order to facilitate the processing of the ears 3, it is generally necessary to open a butt opening 11 corresponding to the ears 3 at the bottom of the box body 1. The butt opening 11 is a mold hole reserved for the molding of the ears 3, thereby realizing the integrated injection molding of the box body 1 and the ears 3, making the processing of the junction box more convenient.

[0057] When the junction box needs to be assembled, the nut is installed in the bearing ear 3 , that is, the nut is placed into the accommodating cavity 31 through the opening of the mounting hole 13 . Then the box body 1 is connected to the side panel 2, that is, the side buckle plate 24 on the side panel 2 is plugged into the side buckle hole 15, wherein a side buckle block 241 is installed on the side buckle plate 24, and the side buckle block 241 is made of elastic materials such as plastic and rubber. In the process of inserting the side buckle plate 24 into the corresponding side buckle hole 15, the groove wall of the side buckle hole 15 exerts pressure on the side buckle block 241, and the side buckle block 241 is elastically deformed under the force and maintains a tendency to reset. When the side panel 2 and the box body 1 are installed, the side buckle block 241 moves out of the side buckle hole 15, and the hole wall of the side buckle hole 15 no longer exerts pressure on the side buckle block 241, and the side buckle block 241 is reset, and the side of the side buckle block 241 close to the inner wall of the box body 1 abuts and cooperates with the corresponding vertical rib 16, thereby limiting the side panel 2 from moving in the direction away from the box body 1, that is, realizing the installation between the side panel 2 and the box body 1.

[0058] In the process of connecting the side panel 2 and the box body 1, the blocking plate 22 on the side panel 2 will be inserted into the corresponding mounting hole 13 so that the blocking plate 22 blocks the opening of the mounting hole 13, thereby preventing the nut from accidentally falling from the opening of the mounting hole 13, thereby achieving the closure of the opening of the mounting hole 13.

[0059] And in the process of connecting the side panel 2 with the box body 1, the bottom plate 21 on the side panel 2 will cover the collision opening 11, that is, the bottom plate 21 will be plugged into the corresponding insertion groove 12 to enter the box body 1, and the bottom plate 21 will cover the collision opening 11, thereby realizing the installation of the side panel 2 and the closure of the mounting hole 13 and the collision opening 11 at the same time.

[0060] By integrating the side panels 2 and the bottom panel 21, the blocking plate 22 seals the mounting hole 13 and the bottom panel 21 seals the mating opening 11 simultaneously with the installation of the side panels 2. No additional process is required to close the mating opening 11 with the bottom panel 21. This simplifies the assembly process of the junction box, shortens the assembly time, and improves assembly efficiency. Furthermore, because the bottom panel 21 is mounted on the side panels 2, the connection between the side panels 2 and the box body 1 is also achieved simultaneously with the connection between the bottom panel 21 and the box body 1. No additional structure is required to achieve the connection between the bottom panel 21 and the box body 1, reducing the number of required parts and lowering the assembly cost of the junction box.

[0061] Example 2:

[0062] The difference between Example 2 of the present application and Example 1 is that:

[0063] Reference Figure 6The box body 1 is installed with an alignment component 5 used as a horizontal alignment reference. The alignment component 5 includes a plurality of marking grooves 51 opened on the box body 1. The marking grooves 51 are located on a side of the box body 1 away from the collision port 11.

[0064] Reference Figure 7 、 Figure 8 and Figure 9 The groove wall of the mounting hole 13 is provided with an upper buckle groove 131, and the blocking plate 22 is fixedly connected with an upper buckle block 221 that is buckled into the upper buckle groove 131. The upper buckle block 221 is made of elastic materials such as plastic and rubber, and the upper buckle block 221 is arranged in an inclined surface on the side close to the accommodating cavity 31.

[0065] Reference Figure 7 、 Figure 8 and Figure 9 The side wall of the box body 1 is provided with an insertion hole 14, and the side panel 2 is fixedly connected to the mud and sand baffle 23 that plugs into the insertion hole 14. When the box body 1 and the side panel 2 are connected, the mud and sand baffle 23 passes through the insertion hole 14, covers one end of the through hole 32, and is located on the side of the bearing ear 3 away from the collision opening 11.

[0066] Reference Figure 7 、 Figure 8 and Figure 9 The side panel 2 is connected to the mud and sand baffle 23 through a breaking portion 4, which is easy to break. The breaking portion 4 uses a breaking rod 41 made of an easy-to-break material such as plastic. One end of the breaking rod 41 is fixedly connected to the side panel 2, and the other end is fixedly connected to the mud and sand baffle 23.

[0067] The implementation principle of a wall switch wiring bottom box in Example 2 of the present application is as follows:

[0068] When the staff installs the junction box on the wall, they will align the junction box and the wall horizontally. The staff usually uses an infrared level or a plumb line, and the marked wire trough 51 can be used as a flush reference. The staff can adjust the installation position of the junction box through the alignment component 5, reducing the risk of the junction box being installed crookedly and improving the installation quality of the junction box.

[0069] When the side panel 2 is installed on the box body 1, the blocking plate 22 is inserted into the mounting hole 13 so that the blocking plate 22 blocks the opening of the mounting hole 13. During the insertion of the blocking plate 22, the wall of the mounting hole 13 exerts pressure on the upper buckle block 221. The upper buckle block 221 is made of elastic material. The upper buckle block 221 is elastically deformed under the force and maintains a tendency to reset. When the insertion of the blocking plate 22 is completed, the upper buckle block 221 on the blocking plate 22 moves to the notch of the upper buckle groove 131. The wall of the mounting hole 13 no longer exerts pressure on the upper buckle block 221. The upper buckle block 221 is reset and engages with the upper buckle groove 131, thereby further strengthening the connection between the blocking plate 22 and the box body 1, improving the blocking effect of the blocking plate 22 on the opening of the mounting hole 13, reducing the risk of mud and sand entering the accommodating cavity 31 through the mounting hole 13 during the installation process to affect the subsequent installation of the junction box, and improving the stability of the junction box.

[0070] In the process of installing the side panel 2 onto the box body 1, the mud and sand baffle 23 is plugged into the plug hole 14, so that the mud and sand baffle 23 enters the box body 1 through the plug hole 14, and when the box body 1 is connected to the side panel 2, the mud and sand baffle 23 covers one end of the through hole 32, and is located on the side of the ear 3 away from the collision hole 11, thereby preventing mud and sand from entering the accommodating chamber 31 through the upper end of the through hole 32 during the installation of the junction box body 1, reducing the risk of mud and sand entering the accommodating chamber 31 and affecting the use of the nut, and improving the stability of the junction base box.

[0071] When it is necessary to connect the box body 1 and the cover plate, the screw on the cover plate needs to be threaded into the through-hole 32 and threaded with the corresponding nut, that is, the mud and sand baffle 23 no longer needs to cover the upper end opening of the through-hole 32, wherein the side panel 2 and the mud and sand baffle 23 are connected by the breaking portion 4, wherein the breaking portion 4 adopts a breaking rod 41 made of an easy-to-break material such as plastic. Therefore, it is only necessary to apply external force to the breaking rod 41 to break the breaking rod 41, thereby canceling the connection between the side panel 2 and the mud and sand baffle 23, so that the mud and sand baffle 23 no longer covers the opening of the through-hole 32, the operation is simple and convenient, and the convenience of using the junction box is improved.
