Problems solved by technology

Therefore, the installation holes on the junction box for fixing electrical components (such as wall sockets, wall switches, etc.) can only have two angles, which limits the diverse needs of users
[0006] (3) In the prior art, after the junction box is installed into the embedded hole, quick-drying cement or viscous glue needs to be used for fixing, so the operation steps are more complicated
At the same time, after the junction box is fixed, the direction cannot be adjusted and it is difficult to take it out from the embedded hole, which also limits the needs of users who need to change the installation position to a certain extent.

Embodiment 1

[0039] Such as Figure 1~3 As shown, a circular expansion junction box includes an outer expansion sleeve 3, an inner box body 1 is placed inside the outer expansion sleeve 3, the cross sections of the inner box body 1 and the outer expansion sleeve 3 are circular, and the inner box body There is a gap between the outer circumference of 1 and the inner circumference of the outer expansion sleeve 3. The upper and lower openings of the outer expansion sleeve 3 are respectively provided with an upper cone 2 and a lower cone 4 at the upper and lower openings of the outer expansion sleeve 3, and the upper cone 2 and the lower cone 4 enter from the corresponding ports of the outer expansion sleeve 3 respectively. The outer expansion sleeve 3 is then threadedly connected with the inner box body 1 respectively.

[0040] Such as Figure 4 As shown, the outer expansion sheath 3 includes an outer expansion sheath body 5, the outer expansion sheath body 5 is a cylindrical shape with the...

Embodiment 2

[0053] The difference between this embodiment and embodiment 1 is: as Figure 8~10 As shown, one section of the lower cone 4 in the present embodiment is closed, and a base plate 17 is provided at the bottom (thicker end) of the lower cone 4, and a base plate fastening hole 18 is provided at the center of the base plate 17, and the base plate fastening hole 18 It is a hexagonal hole, and the circumferential rotation of the lower cone 4 can be realized by an Allen wrench matched with the fastening hole 18 of the bottom plate. At the same time, the closed end of the inner box body 1 is provided with a through hole with a diameter larger than the fastening hole 18 of the bottom plate and corresponding to the front and back of the fastening hole 18 of the bottom plate.

[0054] When assembling the circular expansion type junction box, after the pre-tightening is completed, the hexagonal wrench can be used to pass through the inner box body 1 and then be installed with the fastenin...

Abstract

The invention provides a circular expansion type wiring cassette, which belongs to the technical field of electrical equipment. The cassette comprises an inner cassette body (1) and an outer expansion sleeve (3). Expansion pieces (19) are arranged on both ends of the outer expansion sleeve (3). Two cone parts are arranged on both ends of the outer expansion sleeve (3) respectively. The cone parts match the expansion pieces (19) and are threadedly connected with the inner cassette body (1) on the corresponding side. An inner cassette body threading hole (11) and an outer expansion sleeve threading hole (6) are respectively arranged on the inner cassette body (1) and the outer expansion sleeve (3). The inner cassette body threading hole (11) matches the outer expansion sleeve threading hole (6) inside and outside to connect the outer expansion sleeve (3) and the inner cassette body (1). In the circular expansion type wiring cassette, an expansion bar and the matched cone parts are arranged, so that the circular expansion type wiring cassette is easily fixed. The whole circular expansion type wiring cassette is circular, so that mounting holes fixed with electrical appliance components are multi-angle. The multi-angle mounting holes are easy to realize personalized user needs.

Description

technical field [0001] The utility model relates to a circular expansion junction box, which belongs to the technical field of electrical equipment. Background technique [0002] In construction projects or various decoration constructions, junction boxes are necessary electrician auxiliary tools. The junction box is generally pre-buried in the wall, and at the same time it plays the role of connecting wires, transitioning various electrical circuits, and protecting the safety of the line. Various indoor wall switches or wall sockets are connected to the lines in the junction box, and then It is fixed on the surface of the junction box, thus ensuring the cleanliness and beauty of the wall. [0003] In the prior art, the junction boxes are all square, and there are threading holes on both sides of the junction box. After the junction box is placed in the pre-buried hole on the wall, the wires in the wall are introduced into the junction box, and then Fix the junction box in...
