Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a positioning device for installing a rear-mounted junction box. Background Technology

[0002] Currently, junction boxes in interior masonry walls are installed after the masonry is completed. The process involves chiseling grooves for junction boxes and conduits within the masonry after the masonry is finished. After the junction boxes and conduits are installed, the gaps are filled with mortar. However, the mortar is prone to loosening before it hardens, and mortar shrinkage can affect the squareness of the junction boxes and may even cause them to bulge. In particular, when installing multiple junction boxes, the spacing and neatness between the boxes are inevitably affected, making it difficult to meet the acceptance specifications and affecting the aesthetics of the final socket installation.

[0003] Based on this, this application provides a positioning device that can improve the installation quality of masonry junction boxes to solve the above problems. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art. Therefore, the present invention provides a positioning device that can improve the installation quality of masonry junction boxes.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A positioning device for installing a retrofitted junction box is provided, comprising a fixing plate and a fixing strip. The fixing plate is fixedly installed in the mounting hole of the wall by means of an expansion plug and screws to seal the junction box groove opened in the wall. The fixing plate has a number of perforated holes equal to the number of junction boxes to be installed. The perforated holes do not obstruct the screw holes inside the junction boxes. Each perforated hole also has an embedding groove matching the junction box on its back, and a sealing gasket is provided in the embedding groove. The two ends of the fixing strip are respectively fixedly installed on the fixing plate by screws. The fixing strip has fixing holes corresponding to the screw holes of each junction box. Each junction box is tightened into the embedding groove of the fixing plate by screws passing through the fixing holes.

[0007] In some alternative embodiments, the perforation hole is a round hole or a square hole.

[0008] In some alternative implementations, the depth of the embedding groove is equal to the thickness of the decorative panel on the wall.

[0009] In some alternative embodiments, handles are installed at both ends of the fixing plate.

[0010] In some alternative embodiments, a bubble level is also provided in the lower part of the panel of the fixing plate.

[0011] In some alternative embodiments, the top of the fixing plate is provided with a groove for pouring cement mortar into the junction box groove, and a baffle for sealing the groove is fixed on the panel of the fixing plate, and the top of the baffle is provided with an outwardly bent guide plate.

[0012] In some alternative implementations, the two ends of the groove do not extend beyond the two ends of the junction box groove.

[0013] In some alternative implementations, adjacent junction boxes are connected by a short pipe section, and each junction box is covered with tape to prevent cement mortar from entering the junction box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model can use a fixing strip to fix the junction box in the embedded groove of the fixing plate, and the fixing plate is fixed to the wall to seal the junction box groove, so that a cement mortar pouring cavity is formed between the junction box groove and the fixing plate. This method of installing junction boxes can effectively ensure the installation quality of junction boxes. Attached Figure Description

[0029] Example 1

[0030] Please see the appendix Figure 2 and attached Figure 3 This embodiment provides a positioning device for installing a rear-mounted junction box, including a fixing plate 1 and a fixing strip 2, wherein:

[0031] The fixing plate 1 is larger than the junction box groove 10. The fixing plate 1 has the same number of perforated holes 1.1 as the number of junction boxes 30 to be installed. The size of the perforated holes 1.1 should be such that they do not obstruct the screw holes 30.1 inside the junction box 30. Each perforated hole 1.1 also has an insert groove 1.2 on its back that matches the junction box 30. A sealing gasket is provided in the insert groove 1.2 to seal the opening of the junction box and prevent cement mortar from leaking between the junction box and the fixing plate. In this embodiment, the perforated holes 1.1 can be square or round.

[0032] The two ends of the fixing strip 2 are respectively fixed to the fixing plate 1 by screws, and the fixing strip 2 is provided with fixing holes 2.1 corresponding to the screw holes 3.1 of each wire box 30. Each wire box is tightened in the embedding groove 1.2 of the fixing plate 1 by screws passing through the fixing holes 2.1, which can realize the reliable fixing of the wire box.

[0033] In specific implementation, see attached Figure 1 and attached Figure 4 As shown, first drill mounting holes in the wall according to the installation position of the fixing plate 1, and insert expansion plugs into the mounting holes; then tighten each junction box 30 onto the fixing plate 1 by passing screws through the fixing holes 2.1 of the fixing strip 2; as shown in the attached diagram. Figure 5 As shown, adjacent junction boxes 30 are connected by a short section pipe 40, and then a conduit 50 is connected to one of the junction boxes. Each junction box 30 is then covered with tape (the short section pipe and the connection between the conduit and the junction box need to be covered with tape) to prevent cement mortar from entering the junction box. Finally, the fixing plate 1 is fastened into the junction box groove 10, and screws are tightened into the expansion plugs in the mounting holes, forming a cement mortar pouring cavity between the junction box groove 10 and the fixing plate 1. In this embodiment, cement mortar can be poured into the pouring cavity through the conduit groove 20 (the fluidity of the cement mortar can be adjusted as needed). After the cement mortar has solidified, the positioning device can be removed for reuse.

[0034] Preferably, in this embodiment, the depth of the embedded groove 1.2 is equal to the thickness of the decorative panel on the wall, so that after the decorative panel is installed, the surface of the junction box is flush with the decorative panel.

[0035] Preferably, the fixing plate 1 in this embodiment is equipped with handles 3 at both ends to facilitate the installation and removal of the fixing plate.

[0036] Preferably, the lower part of the panel of the fixing plate 1 is also provided with a bubble level 4 to facilitate observation of the levelness of the installation.

[0037] Example 2

[0038] Based on Example 1, as shown in the appendix Figure 2 To be continued Figure 4 As shown, in this embodiment, a groove 1.3 for pouring cement mortar into the junction box groove 30 is provided on the top of the fixing plate 1. Preferably, the two ends of the groove 1.3 do not exceed the two ends of the junction box groove 10. A baffle 5 for sealing the groove 1.3 is fixed on the panel of the fixing plate. The top of the baffle 5 is provided with an outwardly bent guide plate 5.1 to facilitate pouring cement mortar into the groove.

[0039] This embodiment enables the pouring of cement mortar from above the junction box groove into it. Compared with the pouring method from inside the conduit groove in Embodiment 1, this reduces the difficulty of pouring cement mortar and improves the pouring efficiency. At the same time, this method is also more suitable for the side-by-side installation of more than three junction boxes.

[0040] It is worth noting that after the pouring is completed in this embodiment, some cement mortar will remain in the groove, which will protrude from the wall surface after it solidifies. Since cement mortar is easy to remove after it has solidified, the protruding mortar on the wall can be removed by tapping it off along the wall surface with a trowel.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
