Description

Technical Field

[0001] The utility model relates to the technical field of a junction box, and more specifically to a junction box which is easy to close. Background Art

[0002] The junction box includes a box cover and a box body with an opening at the top. A common junction box is rectangular in shape. Threaded holes are arranged around the top of the box body, and through holes are arranged around the box cover corresponding to the positions of the threaded holes. The box cover is fixedly connected to the threaded holes on the box body by bolts passing through the through holes thereon. When disassembling the box cover, it is necessary to unscrew the bolts around the box cover, which is time-consuming and laborious, and the unscrewed bolts are small in size and easy to lose. Therefore, it is necessary to improve the traditional junction box. Utility Model Content

[0003] The technical problem to be solved by the utility model is that it is complicated and time-consuming to disassemble and assemble the box cover of the traditional junction box, and thus a junction box with easy cover closure is provided to solve the above problem.

[0005] A junction box that is easy to close, comprising a box cover and a box body with an opening at the top, wherein sliding strips are arranged on opposite sides of the top of the box body, and sliding grooves for sliding connection with the sliding strips are arranged on opposite sides of the box cover, and a connecting column is arranged on a side wall of the top of the box body located between the two sliding strips, and the connecting column extends to the bottom wall of the box body, and a threaded hole is arranged on the top of the connecting column. An avoidance opening for the box cover to slide is arranged on the other side wall of the top of the box body corresponding to the connecting column, and a through hole for the bolt to pass through is arranged at one end of the box cover.

[0006] Preferably: the side wall of the box body provided with the connecting column is configured as an abutting side plate, the other side wall of the box body corresponding to the abutting side plate is configured as an open side plate, and the height of the connecting column is smaller than the height of the open side plate.

[0007] Preferably, the connecting column is integrally arranged with the abutting side plate.

[0008] Preferably: the box cover and the box body are both made of plastic, the through hole and the threaded hole are both provided with an annular insert made of metal material, and threads are arranged on the outer wall and the inner wall of the annular insert in the threaded hole.

[0009] Preferably, the other end of the slide bar that contacts the side plate is provided with a metal insert or covered with a metal sheet.

[0010] Preferably, the box cover is made of a transparent material, or is made of a transparent material in the through hole area.

[0011] The beneficial effects of the present utility model are as follows: The box cover is slidably connected to the box body. When the box cover and the box body need to be fixed, one end of the box cover is pushed along the direction of the slide bar, and then the box cover and the connecting column are fixedly connected by using bolts; when the box cover needs to be disassembled, loosen the bolts to separate the bolts from the connecting column, and then slide the box cover to operate on the wires in the box body. The operation is convenient, time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0017] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0018] In the present utility model, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of the respective components, but the above orientation terms are not used to limit the present utility model.

[0019] According to Figures 1-3As shown in the figure, a junction box facilitating lid closing includes a lid 1 and a box body 2 with an opening at the top. On opposite sides of the top of the box body 2, there are sliding strips 23. On opposite sides of the lid 1, there are sliding grooves 12 for slidably connecting with the sliding strips 23. On one side wall between the two sliding strips 23 at the top of the box body 2, there is a connecting column 3. The connecting column 3 extends to the bottom wall of the box body 2. A threaded hole is opened at the top of the connecting column 3. On the other side wall of the box body 2 corresponding to the connecting column 3, there is an avoidance opening for the lid 1 to slide. A through hole 11 for a bolt to pass through is opened at one end of the lid 1. The lid 1 is slidably connected to the box body 2. When the lid 1 and the box body 2 need to be fixed, push one end of the lid 1 along the direction of the sliding strip 23, and then use a bolt to fixedly connect the lid 1 and the connecting column 3. When it is necessary to disassemble the lid 1, loosen the bolt to separate the bolt from the connecting column 3, and then slide the lid 1 to operate on the wires in the box body 2. The operation is convenient, time-saving and labor-saving.

[0020] As shown in Figures 1-3 the figure, the side wall of the box body 2 where the connecting column 3 is provided is set as a contact side plate 21. The connecting column 3 is integrally provided with the contact side plate 21. The other side wall of the box body 2 corresponding to the contact side plate 21 is set as an opening side plate 22. The height of the connecting column 3 is less than the height of the opening side plate 22. Both the lid 1 and the box body 2 are made of plastic. The through hole 11 and the threaded hole are both provided with annular inserts 111 made of metal materials. Threads are provided on both the outer wall and the inner wall of the annular insert 111 in the threaded hole. The lid 1 is made of a transparent material, or is made of a transparent material in the area of the through hole 11. A metal insert block or a metal sheet is provided at the other end of the sliding strip 23 relative to the contact side plate 21.

[0021] Combined with Figures 1-3 the figure, when disassembling the lid 1, unscrew the bolt by ⅓ of its height. The part of the bolt at the bottom end of the lid 1 protrudes. When sliding the lid 1, it is avoided that the lid is completely separated from the box body 2, which also facilitates re-closing the lid later. In addition, in this application, the transparent material is made of PP or PE material, preferably PE material. Only the position of the lid 1 near the through hole 11 is made of transparent material. This area and the other parts of the lid 1 are integrally formed by injection molding. The annular insert 111 is made of copper or stainless steel material. In this application, copper is preferably selected. The metal insert or the covered stainless steel sheet at one end of the sliding strip 23 is used to increase the strength of the sliding strip 23. Because when the lid 1 slides to one side of the box body 2, most of the weight of the lid 1 is supported by the sliding strip 23, avoiding deformation of the sliding strip 23, and the deformation of the sliding strip 23 will also affect the normal sliding of the lid 1.
