Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and specifically to an embedded mounting junction box. Background Technology

[0002] The function of a junction box is to connect multiple wires to form a circuit path, while preventing electric shock and short circuits, protecting internal connection points from environmental influences, and facilitating maintenance, replacement of wiring or expansion of circuits, thus reducing overall disassembly and modification costs.

[0003] Recessed junction boxes are a commonly used type of junction box. When installed on a suspended ceiling, they are installed in mounting holes that are made in the ceiling. However, since the diameter of the mounting holes made in the ceiling is different, recessed junction boxes are difficult to adapt to the installation requirements of mounting holes with different diameters. Summary of the Invention

[0004] The purpose of this invention is to provide an embedded mounting junction box that solves the aforementioned problems existing in current embedded mounting junction boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An embedded junction box includes a junction box, a mounting bracket, and a sliding bracket. The junction box is connected to the middle of the mounting bracket. Two sliding brackets are provided, spaced apart on the mounting bracket. Each sliding bracket includes a sliding base, a positioning element, and a spring clip. The sliding base is movable along the length of the mounting bracket. The positioning element is provided on the sliding base and can fix the sliding base to the mounting bracket. The spring clip is connected to the top of the sliding base for fixing the junction box in a mounting hole.

[0006] Furthermore, the junction box includes a box body and a box cover. The box body is fixed on the mounting bracket, and the box cover is hinged to the upper end of the box body and snapped together with the box body via a snap-fit ​​connector.

[0007] Furthermore, both the box body and the lid are equipped with threading holes for threading wires.

[0008] Furthermore, the snap-fit ​​component includes a snap-fit ​​groove disposed on the side of the lid, and a corresponding snap-fit ​​protrusion disposed on the side wall of the box body. The snap-fit ​​groove is configured to engage with the snap-fit ​​protrusion to fix the lid to the box body after the lid is placed on the box body.

[0009] Furthermore, a fixing plate is provided at the upper end of the inner wall of the box, and a fixing hole is provided at the edge of the box cover. The fixing plate is connected by screws in the fixing hole to fix the box cover to the box body.

[0010] Furthermore, the bottom of the sliding base is provided with a slider and a locking block. The slider is located between the sliding base and the locking block. The mounting bracket is provided with a sliding groove and a mounting slot along the length direction. The mounting slot is located in the middle of the mounting bracket and the mounting slot and the sliding groove are connected. The mounting slot is used for the locking block to be inserted. The slider is slidably disposed in the sliding groove. The locking block is configured to engage with the sliding groove when the slider is in the sliding groove to prevent the slider from disengaging from the sliding groove.

[0011] Furthermore, the positioning component includes a positioning sleeve and a positioning claw. The positioning sleeve is fitted onto the sliding base, and the positioning claw is located at the lower end of the positioning sleeve. The mounting bracket has multiple sets of positioning holes along its length, and the positioning claw is used to insert into the positioning holes to position the sliding bracket on the mounting bracket.

[0012] Furthermore, the slide is provided with screw holes, and the box can be fixed to the mounting bracket by placing screws in the screw holes.

[0013] Furthermore, the mounting bracket has locking claws at both ends for engaging with the luminaire to connect to it.

[0014] The beneficial effects of this utility model are: This utility model's embedded mounting junction box, through its adjustable sliding bracket structure, allows the junction box to adapt to mounting holes of different diameters, greatly improving the product's versatility. It adopts a dual fixing method, which can be quickly installed by snap-fit ​​or reliably fixed by screws, meeting different usage needs; at the same time, it can be used with lighting fixtures, expanding its application range.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figures 1-6 As shown, this embedded mounting junction box mainly includes a junction box 1, a mounting bracket 2, and two sliding brackets 3. The junction box 1 is fixed in the middle position of the mounting bracket 2, and the two sliding brackets 3 are movably mounted on the mounting bracket 2.

[0019] refer to Figures 1-4 Junction box 1 adopts a split structure, including a box body 11 and a cover 12. The box body 11 is fixed to the mounting bracket 2 with screws, and the cover 12 is connected to the box body 11 via a hinge, allowing it to be opened and closed. A snap-fit ​​groove 14 is provided on the side of the cover 12, and a corresponding snap-fit ​​protrusion 15 is provided on the side wall of the box body 11. When the cover 12 is closed, the snap-fit ​​groove 14 and the snap-fit ​​protrusion 15 engage, achieving quick fixation. Furthermore, a fixing plate 16 is provided at the upper end of the inner wall of the box body 11, and a fixing hole 17 is provided at the edge of the cover 12. Screws can be installed in the fixing holes 17 to connect to the fixing plate 16 for a more secure fixation. Both the box body 11 and the cover 12 have multiple wire-passing holes 13 for wire entry and exit.

[0020] like Figure 5 and Figure 6 As shown, the mounting bracket 2 is machined with a sliding groove 21, a mounting slot 22, and multiple sets of positioning holes 23. The sliding bracket 3 consists of a sliding base 31, a positioning element 32, and a spring buckle 33. The bottom of the sliding base 31 is provided with a slider 311 and a locking block 312. During assembly, the locking block 312 is first inserted into the mounting slot 22, and then the slider 311 is pushed horizontally into the sliding groove 21. At this time, the locking block 312 and the sliding groove 21 form an anti-disengagement locking engagement. The positioning element 32 includes a positioning sleeve 321 fitted on the sliding base 31 and a positioning claw 322 at its lower end. When the sliding bracket 3 moves to the desired position, the positioning claw 322 is inserted into the corresponding positioning hole 23 under the action of elastic force to achieve positioning. The spring buckle 33 is hinged to the top of the sliding base 31 and is used for locking and fixing during installation.

[0021] The mounting bracket 2 has screw holes 24 on its slide groove 21 for fixing the housing 11 with screws. The mounting bracket 2 has locking claws 25 at both ends for connecting other equipment such as lamps.

[0022] During installation, first adjust the positions of the two sliding brackets 3 on the mounting bracket 2 according to the size of the ceiling mounting hole, so that the spacing of the spring clips 33 matches the diameter of the mounting hole. Then, fix the junction box 1 to the mounting bracket 2 with screws. Connect the wires by passing them through the wire hole 13 into the junction box 1. Finally, lift the entire device, compress the spring clips 33 to pass them through the mounting hole, and release them to complete the fixation. For a more secure fixation, additional screws can be used through the fixing holes 17 on the box cover.

[0023] This structure allows the same junction box to accommodate mounting holes of different sizes, greatly improving the product's applicability and ease of installation.

[0024] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
