Description

Technical Field

[0001] This utility model relates to the field of pipeline construction in building electrical engineering, specifically a connection structure between a PVC junction box and a panel. Background Technology

[0002] Junction boxes are essential electrical auxiliary tools in building construction or various decoration projects. They can connect wires, ensure the transition of various electrical circuits, and protect the safety of the circuits. Junction boxes are mainly used for the installation of various switches, sockets, and other electrical wiring panels.

[0003] Currently, the connection between junction boxes and panels on the market involves setting self-tapping screw posts on the junction box, and connecting the panel to the self-tapping screw posts with screws. The self-tapping screw posts are made of plastic, and after repeated disassembly and use, the connection strength of the self-tapping screw posts decreases, thus affecting the firmness of the connection with the panel. This utility model provides a connection structure between a PVC junction box and a panel, which makes the panel easy to install and easy to disassemble. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a connection structure between a PVC junction box and a panel.

[0005] A connection structure between a PVC junction box and a panel includes a junction box body and a panel installed at its open end. A limiting block is provided on the inner wall of the junction box body. An annular connecting protrusion is provided on the side of the panel near the junction box body. The connecting protrusion is inserted into the inner cavity of the limiting box body. A longitudinal groove extending from bottom to top is provided on the connecting protrusion. A transverse groove extending along the outer wall of the connecting protrusion is also provided on the connecting protrusion. The longitudinal groove and the transverse groove are in communication. When installing the panel, the limiting block is inserted into the longitudinal groove. The panel is rotated so that the limiting block enters the transverse groove, thereby limiting the panel.

[0006] Furthermore, a limiting protrusion is provided at the bottom of the transverse groove.

[0007] Furthermore, a magnet is provided on the wall of the transverse groove away from the longitudinal groove, the limiting block has an arc-shaped structure, and a magnetic column that attracts the magnet is provided on the side of the limiting block near the magnet.

[0008] Furthermore, the side wall of the junction box body is provided with two sets of fixing mechanisms for connecting with the reinforcing bars. The fixing mechanism includes two arc-shaped clamps that are adapted to the outer wall of the reinforcing bars. The side of the two arc-shaped clamps away from the junction box body is an open end, and the width of the open end of the two arc-shaped clamps is smaller than the diameter of the reinforcing bars.

[0009] Furthermore, the outer wall of the arc-shaped clamp is provided with an installation protrusion that is inclined toward the junction box body, and a bolt is threaded onto the installation protrusion, the bottom of which abuts against the reinforcing bar.

[0010] Furthermore, the edge of the panel away from the junction box body is provided with an anti-slip layer.

[0011] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are: the panel of this utility model is easy and quick to install, does not require the tightening of self-tapping screws, and the junction box is fixedly installed on the steel bar by setting a fixing mechanism, thereby realizing the pre-installation of the junction box.

[0017] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0018] according to Figure 1-4As shown, a connection structure between a PVC junction box and a panel 3 includes a junction box body 1 and a panel 3 installed at its open end. A limiting block 2 is provided on the inner wall of the junction box body 1. An annular connecting protrusion 4 is provided on the side of the panel 3 near the junction box body 1. The connecting protrusion 4 is inserted into the inner cavity of the limiting box body. A longitudinal groove 5 extending from bottom to top is provided on the connecting protrusion 4. A transverse groove 6 extending along the outer wall of the connecting protrusion 4 is also provided on the connecting protrusion 4. The longitudinal groove 5 and the transverse groove 6 are connected. When the panel 3 is installed, the limiting block 2 is inserted into the longitudinal groove 5. The panel 3 is rotated so that the limiting block 2 enters the transverse groove 6, thereby limiting the panel 3.

[0019] In the above specific technical solution, panel 3 is easy and quick to install, and does not require tightening self-tapping screws.

[0020] The bottom of the transverse groove 6 is provided with a limiting protrusion 7, which can prevent the panel 3 from detaching from the junction box body 1 when the limiting block 2 is in the transverse groove 6.

[0021] The transverse groove 6 is provided with a magnet 8 on the groove wall away from the longitudinal groove 5. The limiting block 2 has an arc-shaped structure. The side of the limiting block 2 near the magnet 8 is provided with a magnetic column 9 that attracts the magnet 8. Through the cooperation of the magnet 8 and the magnetic column 9, the stability of the connection between the junction box body 1 and the panel 3 can be improved.

[0022] The side wall of the junction box body 1 is provided with two sets of fixing mechanisms for connecting with the reinforcing bar 14. The fixing mechanism includes two arc-shaped clamps 10 adapted to the outer wall of the reinforcing bar 14. The side of the two arc-shaped clamps 10 away from the junction box body 1 is an open end, and the width of the open end of the two arc-shaped clamps 10 is smaller than the diameter of the reinforcing bar 14.

[0023] The outer wall of the arc-shaped clamp 10 is provided with an installation protrusion 11 that is inclined toward the junction box body 1. A bolt 12 is threaded onto the installation protrusion 11, and the bottom of the bolt 12 abuts against the reinforcing bar 14.

[0024] In the above-mentioned specific technical solution, the junction box often needs to be pre-installed during daily use. During pre-installation, the reinforcing bar 14 is inserted from the open end of the arc-shaped clamp 10 between the two arc-shaped clamps 10. The width of the open end of the arc-shaped clamp 10 is smaller than the diameter of the reinforcing bar 14 to prevent the reinforcing bar 14 from detaching from the arc-shaped clamp 10. By tightening the bolt 12, the bolt 12 is made to tightly abut against the reinforcing bar 14, thereby firmly installing the junction box on the reinforcing bar 14.

[0025] The edge of the panel 3 away from the junction box body 1 is provided with an anti-slip layer 13. This facilitates the installation and removal of the panel 3.
