Description

Technical Field

[0001] This utility model belongs to the field of junction box technology, and specifically relates to a junction box that is easy to assemble and disassemble. Background Technology

[0002] In home renovation, junction boxes are one of the electrical accessories. Because the wires used in renovation run through conduits, junction boxes are used as a transition at the joints of the wires. The conduits are connected to the junction boxes, and the wires inside the conduits are connected in the junction boxes, which serves to protect and connect the wires. This is what a junction box is.

[0003] Currently, Chinese utility model patent CN217720926U discloses a motor junction box that is easy to disassemble and maintain. The junction box includes a main body, a protective mechanism on the top, a transmission mechanism inside the protective mechanism, and fixing mechanisms on both sides of the inner wall of the main body. The protective mechanism also includes an adjustment mechanism comprising a connecting block, a drive plate, a bearing, a drive rod, and an adjustment head. Two connecting blocks are rotatably mounted on the rear side of the inner wall of the protective mechanism, and a bearing with one end penetrating and extending to the front of the protective mechanism is rotatably mounted on the rear side of the inner wall. This easy-to-disassemble and maintain motor junction box, with its adjustment mechanism, transmission mechanism, protective mechanism, and fixing mechanism, facilitates the disassembly and assembly of the top cover from the main body, minimizing the need for tools and enabling quick disassembly and maintenance, thus improving maintenance efficiency and convenience.

[0004] In summary, although this junction box can achieve tool-free assembly and disassembly, it still has certain problems in use. For example, the junction box uses a rotating adjustment head to move the drive plate and the drive rod, which in turn moves the fixed block on the movable block into the fixed groove. Although this can achieve the purpose of fixing the shell and the cover, the spring has elastic force. Under the elastic force of the spring, the movable block moves the drive rod, and under the action of the two drive rods, the drive plate will rotate, which can easily cause the shell and the cover to separate. This makes it impractical. At the same time, the junction box is fixed to the surface of the wire inlet with a nut, but there is no structure to improve the sealing between the wire inlet and the nut. External moisture can easily enter the interior of the junction box through the gap between the two, affecting the internal circuit of the junction box. Utility Model Content

[0005] The purpose of this utility model is to provide a junction box that is easy to assemble and disassemble, with the advantages of strong practicality and good sealing performance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a junction box that is easy to assemble and disassemble, comprising a housing, a cover provided on the top of the housing, a slot provided inside the housing, a connecting rod rotatably connected to the top of the cover, one end of the connecting rod penetrating to the bottom of the cover and equipped with a locking mechanism, a rotating disk fixedly sleeved on the top of the connecting rod, a return spring sleeved with the connecting rod provided at the bottom of the rotating disk, the two ends of the return spring respectively engaging with the bottom of the rotating disk and the top of the cover, a through head communicating with both the front and back of the housing, a limit cap threadedly connected to the surface of the through head, an annular ear fitted at the end of the through head near the limit cap, and a rubber sleeve covering the surface of the annular ear.

[0007] The above technical solution is as follows: This utility model incorporates a return spring between the rotating disk and the cover. When the cover needs to be disassembled, the rotating disk simply rotates to disengage the locking tooth plate from the slot, thus separating the shell and the cover. When the rotating disk is released, the connecting rod rotates in the opposite direction under the stress of the return spring, causing the locking tooth plate in the locking mechanism to re-engage into the slot, thereby limiting the position of the cover and the shell and improving practicality. Furthermore, an annular ear is installed at the through-end, with a rubber sleeve covering it. When external wires need to be connected, the rubber sleeve is simply opened, the cable is inserted, and the inlet of the rubber sleeve is secured to the surface of the cable. Tightening the limiting cap compresses the rubber sleeve, making the contact between the rubber sleeve and the cable tighter and improving waterproof performance.

[0008] The present invention is further configured such that the locking mechanism includes a gear fixedly sleeved with the connecting rod, the surface of the gear meshing with a locking tooth plate, and the locking tooth plate engaging with a locking groove.

[0009] Using the above technical solution: When the connecting rod is rotated, the two locking teeth can be moved towards the center position, so that there is enough space between the locking teeth and the cover. When the cover is fastened onto the housing, the connecting rod is released. Under the action of the return spring, the connecting rod rotates in the opposite direction, so that under the action of the gear, it drives the locking teeth to be locked into the slot, thus limiting the position of the cover and the housing.

[0010] The present invention is further configured such that the number of slots is four, and they are symmetrically opened on the inner walls of both sides of the housing, and the number of positioning teeth is two, with the two positioning teeth being staggered on both sides of the gear.

[0011] The above technical solution facilitates the engagement of the cover and the shell without distinguishing between the left and right ends, and allows the gears to simultaneously drive the two locking tooth plates to move.

[0012] The present invention is further configured such that a sliding block is fixedly connected to the bottom of the cover, and a sliding groove is provided on the surface of the locking tooth plate to slide and connect with the sliding block.

[0013] The above technical solution is adopted: the locking toothed plate is slidably limited.

[0014] The present invention is further configured such that a mounting base is fixedly connected inside the housing, and a connecting groove is provided on the top of the mounting base. The number of connecting grooves is four, and a conductive block is fixedly connected between two of the connecting grooves.

[0015] The above technical solution facilitates the connection between two external wires.

[0016] The present invention is further configured such that a clamping block is provided inside the connecting groove, and a limit bolt is threadedly connected to the top of the clamping block, and the limit bolt is threadedly connected to the mounting base.

[0017] The above technical solution facilitates the fixing of external wires onto the conductive block.

[0018] The present invention is further provided that a sealing ring is bonded to the edge of the surface step of the housing.

[0019] The above technical solution is adopted to seal the space between the shell and the cover.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model incorporates a return spring between the rotating disk and the cover. When the cover needs to be disassembled, the rotating disk simply needs to be rotated to disengage the locking toothed plate from the slot, thus separating the shell and the cover. When the rotating disk is released, the connecting rod rotates in the opposite direction under the stress of the return spring, causing the locking toothed plate in the locking mechanism to re-engage into the slot, thereby limiting the position of the cover and the shell and improving practicality.

[0022] 2. This utility model has a ring-shaped ear installed at the through-end, and a rubber sleeve is fitted on the ring-shaped ear. When the external wire needs to be connected, simply open the rubber sleeve, insert the cable, and let the inlet of the rubber sleeve be stuck on the surface of the cable. Tighten the limiting cap to compress the rubber sleeve, so that the contact between the rubber sleeve and the cable is tighter and the waterproof performance is improved. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A junction box for easy assembly and disassembly includes a housing 1. A mounting base 14 is fixedly connected inside the housing 1. The top of the mounting base 14 has four connecting slots 15. A conductive block 16 is fixedly connected between two connecting slots 15. The mounting base 14, connecting slots 15, and conductive blocks 16 facilitate the connection between two external wires. A cover 2 is provided on the top of the housing 1. A slot 3 is provided inside the housing 1. A connecting rod 4 is rotatably connected to the top of the cover 2. One end of the connecting rod 4 extends to the bottom of the cover 2 and is fitted with a locking mechanism 5. The locking mechanism 5 includes a connecting rod... The connecting rod 4 is fixedly sleeved with a gear 51. A locking toothed plate 52 meshes with the surface of the gear 51 and engages with a slot 3. By setting the gear 51 and locking toothed plate 52, when the connecting rod 4 is rotated, the two locking toothed plates 52 can be moved towards the center position, providing sufficient space between the locking toothed plates 52 and the cover 2. When the cover 2 is fastened onto the housing 1, the connecting rod 4 is released. Under the action of the return spring 7, the connecting rod 4 rotates in the opposite direction, causing the locking toothed plate 52 to engage with the slot 3 under the action of the gear 51, thus limiting the position of the cover 2 and the housing 1. The top of the connecting rod 4 is fixedly sleeved. A rotating disk 6 has a return spring 7 fitted onto the bottom of the rotating disk 6 and connected to the connecting rod 4. The two ends of the return spring 7 engage with the bottom of the rotating disk 6 and the top of the cover 2, respectively. Four slots 3 are symmetrically located on the inner walls of both sides of the housing 1. Two positioning teeth 52 are positioned offset from the gear 51 on both sides. The arrangement of four slots 3 symmetrically located on the inner walls of both sides of the housing 1 and two positioning teeth 52 offset from the gear 51 facilitates the connection between the cover 2 and the gear 4. After the housing 1 is snapped in place, the left and right ends are not separated, and the gear 51 drives the two locking tooth plates 52 to move simultaneously. The bottom of the cover 2 is fixedly connected to a sliding block 12. The surface of the locking tooth plate 52 is provided with a sliding groove 13 that slides and connects with the sliding block 12. By setting the sliding block 12 and the sliding groove 13, the locking tooth plate 52 is slidably limited. The inside of the connecting groove 15 is provided with a pressing block 17. The top of the pressing block 17 is threadedly connected to a limit bolt 18. The limit bolt 18 is threadedly connected to the mounting base 14. By setting the pressing block 17 and the limit bolt 18, it is convenient to fix the external wires on the conductive block 16.

[0032] Brief description of the usage process: When it is necessary to disassemble the cover 2 on the housing 1, simply rotate the rotating disk 6. The rotation of the rotating disk 6 drives the connecting rod 4 to rotate, and the rotation of the connecting rod 4 drives the gear 51 to rotate. This moves the two locking tooth plates 52 towards the center position, separating the locking tooth plates 52 from the slots 3. The housing 1 and the cover 2 can then be disassembled. When the rotating disk 6 is released, under the action of the return spring 7, the rotating disk 6 rotates in the opposite direction, driving the connecting rod 4 to rotate in the opposite direction. Under the action of the gear 51, the locking tooth plates 52 are engaged in the slots 3, limiting the position of the cover 2 and the housing 1, thus completing the fixation of the housing 1 and the cover 2.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 and Figure 5 A junction box that is easy to assemble and disassemble includes a housing 1, a cover 2 on the top of the housing 1, a slot 3 inside the housing 1, a connecting rod 4 rotatably connected to the top of the cover 2, one end of the connecting rod 4 penetrating to the bottom of the cover 2 and equipped with a locking mechanism 5, a rotating disk 6 fixedly sleeved on the top of the connecting rod 4, a return spring 7 sleeved on the bottom of the rotating disk 6 and connected to the connecting rod 4, the two ends of the return spring 7 being respectively locked to the bottom of the rotating disk 6 and the top of the cover 2, a through head 8 communicating with the front and back of the housing 1, a limit cap 9 threadedly connected to the surface of the through head 8, an annular ear 10 fitted at the end of the through head 8 near the limit cap 9, a rubber sleeve 11 sleeved on the surface of the annular ear 10, and a sealing ring 19 bonded to the edge of the step on the surface of the housing 1. By setting the rubber sleeve 11 and the sealing ring 19, the housing 1 and the cover 2 are sealed.

[0035] Brief description of usage: When external wires need to be connected, simply open the rubber sleeve 11, insert the cable, and make the inlet of the rubber sleeve 11 fit on the surface of the cable. Tighten the limit cap 9 to compress the rubber sleeve 11, making the contact between the rubber sleeve 11 and the cable tighter and improving the waterproof performance.
