Description

Technical Field

[0001] The present application relates to the technical field of junction boxes, and in particular to a seamless junction box. Background Art

[0002] In home decoration, junction box is one of the electrical auxiliary materials, because the wires used for decoration are passed through the wire tube, and the junction box is used as a transition at the joint of the wires (for example, the line is relatively long, or the wire tube needs to turn a corner). The wire tube is connected to the junction box, and the wires in the wire tube are connected in the junction box, which plays the role of protecting the wires and connecting the wires. In order to insert the wiring tube into the junction box, the existing junction box will be provided with a plurality of knock-out holes on the bottom of the box body and the surrounding walls of the box body. In this way, multiple wiring tubes can pass through the knock-out holes, and the safe connection of the wires in the wiring tube is achieved in the junction box. Usually, each knock-out hole is provided with a knock-out piece, and the knock-out piece cover is provided on the knock-out hole to effectively prevent dust or liquid from entering the junction box. At present, there are two ways to form the knock-out hole and the knock-out piece, one is to be integrally injection-molded with the box body, and the other is to be stamped after the box body is injection-molded. Regardless of the molding method, knockout tabs are prone to falling off during transportation or use. Furthermore, since not all reserved knockout holes are used, once a knockout tab falls off, the only option is to seal the unused knockout holes with tape. However, tape ages and falls off easily, allowing dust or cement slurry to enter the junction box through the knockout holes left uncovered by the knockout tabs, affecting the service life and safety of the wires and posing a risk to construction quality.

[0003] A seamless junction box is now provided, which can realize the wiring function while effectively preventing foreign matter such as dust or cement slurry from entering. Utility Model Content

[0042] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0043] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0044] Reference Figures 1-4 The seamless junction box includes: a box body 11, a mounting block 12, a connecting pipe 15, a limiting block 16, a first sealing block 17, and a first plug cover 18.

[0045] Multiple through-holes 14 are provided, symmetrically positioned on the sidewall of the box body 11 and extending through the sidewall of the box body 11. The through-holes 14 on one side are threaded. Two mounting blocks 12 are provided and symmetrically fixedly connected to the box body 11. Each mounting block 12 has a mounting hole 13. Two connecting tubes 15 are provided, each inserted into the two through-holes 14 on the same side. The inner tube walls of the connecting tubes 15 are threaded. Multiple stop blocks 16 are provided and fixedly connected to one end of the connecting tubes 15 at equal intervals. The outer tube wall of the connecting tube 15 away from the stop block 16 is threaded.

[0046] There are two first sealing blocks 17 , which are cylindrical blocks. The outer tube wall of the first sealing block 17 is provided with threads. The first sealing block 17 and the inner wall of the connecting tube 15 are threaded. A first plug cover 18 is fixedly connected to each first sealing block 17 .

[0047] In order to seal the through-hole 14 on the other side, a sealing member is also provided. The sealing member includes: a second sealing block 20, a second plug cover 21, a clamping block 22, and a protruding block 23. Two second sealing blocks 20 are provided. The second sealing blocks 20 are cylindrical blocks with an outer diameter smaller than the aperture of the through-hole 14. The second sealing blocks 20 are respectively inserted into the through-hole 14 on the same side. Each second sealing block 20 is fixedly connected to a second plug cover 21. There are multiple clamping blocks 22, which are fixedly connected to one end wall of the second sealing block 20 at equal intervals. The protruding block 23 is fixedly connected to one end of the clamping block 22. The protruding block 23 presses against the side wall of the internal space of the box body 11 and is provided with a guide angle 19. The clamping blocks 22 and the protruding blocks 23 are made of plastic and are elastic.

[0048] Working or installation process:

[0049] Initial state: The second sealing block 20 is inserted into the through hole 14 on one side, and one end of the protruding block 23 is engaged with the side wall of the internal space of the box body 11. The first sealing block 17 is threadedly connected to the connecting tube 15. The through hole 14 on one side is sealed by the second sealing block 20 and the second plug cover 21, and one end of the connecting tube 15 is sealed by the first sealing block 17 and the first plug cover 18.

[0050] When the junction box needs to be used, the clamping block 22 and the protruding block 23 are pinched so that the clamping block 22 and the protruding block 23 are deformed in the axial direction of the second sealing block 20, so that the protruding block 23 is released from the pressing contact with the inner wall of the box body 11, and the second sealing block 20 is pulled out of the through hole 14, and then the wire is inserted into the through hole 14;

[0051] Rotate the first plug cover 18 in the opposite direction, so that the first plug cover 18 drives the first sealing block 17 to rotate, and the first sealing block 17 is disengaged from the inner wall of the connecting tube 15. Remove the first sealing block 17 from the connecting tube 15, and pass the other wires through the connecting tube 15 and extend them into the interior space of the box body 11 to complete the wiring work with the other wires.

[0052] If a single junction box cannot complete the wiring work and two junction boxes need to be connected, the same operation as above is performed. Remove the two first sealing blocks 17 on one junction box and remove the second sealing block 20 on the same side of the other junction box. Align the connecting pipe 15 from which the first sealing block 17 is removed with the through hole 14 from which the second sealing block 20 is removed and rotate the connecting pipe 15 so that the outer wall of the connecting pipe 15 is threadedly connected to the through hole 14, thereby completing the connection between the two box bodies 11 (such as Figure 3 shown).

[0053] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
