Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wiring dark boxes, and in particular relates to a wiring dark box with replaceable plug buckles. Background Art
[0002] Junction boxes are used in construction projects or various types of decoration construction. They can simultaneously connect wires, ensure the transition of various electrical circuits, and protect the safety of the circuits. In order to maintain the neatness and beauty of the building surface and the convenience of construction, the junction box is generally pre-buried and installed.
[0003] There are generally two types of buckles for junction boxes on the market. One type is a combination buckle with square nuts on the left and right sides of the junction box (such as Figure 5 As shown in the figure), one is to assemble the L-shaped buckle perpendicular to the opening surface of the junction box (as shown in the figure) Figure 6 As shown). In the process of delivery and use of the two buckle assembly structures, if the buckle is not threaded or the thread is damaged, it is difficult to remove the buckle from the main body of the junction box for maintenance and replacement. The process of replacing the buckle is also likely to cause irreversible damage to the junction box. Therefore, it is usually necessary to replace the entire junction box, which is time-consuming, labor-intensive, and inconvenient.
[0004] In view of this, the present utility model is proposed. Utility Model Content
[0005] The utility model hopes to provide a wiring dark box with replaceable plug buckles, and the specific scheme is as follows:
[0006] A junction box with replaceable buckles comprises a box body, threaded buckles are clamped on both sides of the box body, a gap is provided between the threaded buckle and the box body, a plug piece is detachably connected in the gap, and a buckle gap is provided between the plug piece and the threaded buckle.
[0007] A hook is provided on one side of the insert and a hook deformation zone is provided on the other side. The hook is matched with the threaded insert, that is, the hook can be engaged with the threaded insert, and the hook deformation zone is provided so that when the hook is inserted into the gap between the threaded insert and the dark box body, the hook produces elastic deformation to ensure that the insert is smoothly inserted into the bottom of the gap.
[0008] A retaining edge is provided on the top of the inserting piece, and a protrusion is provided on the dark box body. The retaining edge and the protrusion are arranged in cooperation to prevent the inserting piece from shaking left and right when inserted into the gap.
[0009] A first limiting boss is provided on the top of the insert, and a second limiting boss is provided on the cassette body. The first limiting boss and the second limiting boss are arranged in coordination with each other. Since there will be interference after the threaded buckle, the insert and the cassette body are assembled, the first limiting boss and the second limiting boss are clamped together to prevent the plastic insert from falling off.
[0010] The dark box body is provided with reinforcing ribs for enhancing the strength of the plastic part in the dark box body where the threaded buckle is installed.
[0011] The insert is a plastic insert.
[0012] The threaded buckle is a metal threaded buckle.
[0013] The beneficial effects of the utility model are as follows:
[0014] The present application provides a detachable plug-in piece and retains a buckle gap between the plug-in piece and the threaded buckle. After the installation of the cassette, if the threaded buckle is not tapped or the thread is damaged, a tool can be used to reach into the buckle gap to pry out the plug-in piece, and then the threaded buckle can be replaced. This is convenient and quick, avoids damaging the main structure of the cassette, and there is no need to replace the entire cassette, which saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The present invention will be further described below in conjunction with specific implementation methods.
[0023] In the following description, all concepts related to directionality (or orientation) such as up, down, left, right, front and back are with reference to the position state of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be understood as special limitations on the technical solution provided by the utility model.
[0024] like Figure 1-Figure 4 As shown, a wiring junction box with replaceable buckles includes a junction box body 1, threaded buckles 2 are clamped on both sides of the junction box body 1, a gap 3 is provided between the threaded buckle 2 and the junction box body 1, a plug piece 4 is detachably connected in the gap 3, and a buckle gap 5 is provided between the plug piece 4 and the threaded buckle 2.
[0025] A hook is provided on one side of the insert and a hook deformation zone is provided on the other side. The hook is arranged in cooperation with the threaded insert, that is, the hook can be engaged with the threaded insert, and the hook deformation zone is provided so that when the hook is inserted into the gap between the threaded insert and the dark box body, the hook produces elastic deformation to ensure that the insert is smoothly inserted into the bottom of the gap. The insert is a plastic insert and the threaded insert is a metal threaded insert.
[0026] A retaining edge 43 is provided on the top of the insert 4, and a protrusion 11 is provided on the cassette body 1. The retaining edge 43 and the protrusion 11 are arranged in cooperation to prevent the insert 4 from shaking left and right when inserted into the gap 3. A first limiting boss 44 is provided on the top of the insert 4, and a second limiting boss 12 is provided on the cassette body 1. The first limiting boss 44 and the second limiting boss 12 are arranged in cooperation. Since there will be interference after the threaded buckle 2, the insert 4 and the cassette body 1 are assembled, the first limiting boss 44 and the second limiting boss 12 are engaged, which can prevent the plastic insert 4 from falling off. A reinforcing rib 6 is provided on the cassette body 1 to enhance the strength of the plastic part in the cassette body 1 where the threaded buckle 2 is installed.
[0027] Here’s how it works:
[0028] First, the threaded buckle 2 is placed in the wiring dark box body 1, and then the insert piece 4 is inserted from above into the gap 3 between the threaded buckle 2 and the wiring dark box body 1 to fix the threaded buckle 2. Since the hook buckle 41 of the insert piece 4 is provided with a hook buckle deformation area 42 on the back, the hook buckle 41 will produce elastic deformation when inserted into the gap 3 between the threaded buckle 2 and the wiring dark box body 1, ensuring that the insert piece 4 is smoothly inserted into the bottom of the gap 3.
[0029] In order to ensure that the insert 4 is not easy to fall off, a first limiting boss 44 and a second limiting boss 12 are provided on the insert 4 and the wiring dark box body 1. After the threaded buckle 2, the insert 4 and the wiring dark box body 1 are assembled, there is an interference, and the clamping between the first limiting boss 44 and the second limiting boss 12 can prevent the plastic insert 4 from falling off. A retaining edge 43 is also provided on the plastic insert 4, and a protrusion 11 is provided on the dark box body 1. The retaining edge 43 and the protrusion 11 are arranged in cooperation to prevent the insert 4 from shaking left and right when inserted into the gap 3.
[0030] After the installation of the cassette is completed, if the threaded buckle 2 is not tapped or the thread is damaged, a tool can be used to reach into the buckle gap 5 to pry out the insert 4, and then the threaded buckle 2 can be replaced, which is convenient and quick, avoids damaging the structure of the cassette body 1, and there is no need to replace the entire cassette, which saves time and effort.
[0031] The above-mentioned implementation mode is only used to explain the inventive concept of the utility model, and is not intended to limit the protection of the rights of the utility model. Any non-substantial changes to the utility model using this concept shall fall within the protection scope of the utility model.
