Description

Technical Field

[0001] This utility model relates to the field of switch structure technology, and more specifically to a switch pre-embedded bottom box. Background Technology

[0002] A switch is a component used to connect and disconnect circuits, and the embedded junction box (also known as a concealed box or junction box) in a switch is an important basic component in electrical installation, with the following main functions:

[0003] First, the switch panel is fixed: the pre-embedded box is usually made of metal or PVC and is embedded in the wall, providing a stable mounting base for the switch panel. The switch is fixed to the box with screws, ensuring that the panel is flat and not loose.

[0004] Secondly, it protects the wire connections: the internal space of the junction box is used to accommodate the wire connectors (such as live wire, neutral wire, and ground wire) behind the switch, preventing the wires from being exposed and reducing the risk of short circuits, leakage, or mechanical damage.

[0005] Third, standardize the wiring structure: the standardized design of the junction box (such as the 86 type and 118 type) unifies the switch size, ensures the compatibility of switch panels from different brands, and facilitates standardized wiring by electricians.

[0006] Fourthly, fire prevention and insulation: PVC boxes are flame retardant, and metal boxes can shield electromagnetic interference. Both can isolate wires from wall materials, reducing fire hazards.

[0007] Fifth, it facilitates later maintenance: if it is necessary to replace the switch or repair the wiring, you can simply remove the panel to access the wires inside the junction box without damaging the wall.

[0008] Sixth, load-bearing capacity and durability: withstand the mechanical stress of frequent plugging and unplugging or pressing of switches, and avoid directly pulling the wires inside the wall.

[0009] Existing metal back boxes generally use, for example Figure 1 The cross plate 100 shown is bent by line 1001 ( Figure 1 (As shown by the dotted line) The metal base box is formed by bending. During the manufacturing process, after pre-cutting to a specific width, a servo feeder precisely feeds the material into the mold for stamping. After completing details such as the corresponding product holes, the metal sheet is stamped into a cross-shaped plate. Then, the four protruding plates 1002 of the cross plate 100 are bent upwards along the corresponding bending lines 1001 to form the embedded base box. However, this method of bending the cross plate 100 into an embedded base box not only results in significant material waste when cutting the entire plate into a cross shape, but also leaves vertical seams at all four corners of the bent embedded base box, greatly reducing its overall aesthetic appeal.

[0010] Therefore, how to provide a switch pre-embedded bottom box which is more material-saving and more beautiful is a problem to be solved by those skilled in the art. Utility model content

[0011] Therefore, the utility model provides a switch pre-embedded bottom box which is more material-saving and more beautiful.

[0012] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0013] A switch pre-embedded bottom box, comprising:

[0014] A bottom plate;

[0015] A rear side plate, the lower side of the rear side plate is integrally connected with the upper side of the bottom plate;

[0016] A left side plate, the right side of the left side plate is integrally connected with the left side of the bottom plate;

[0039] The technical scheme in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making the creative labor belong to the range of protection of the utility model.

[0040] As shown in Figures 2-9 The utility model discloses a switch pre -buried bottom box, comprising:

[0041] Bottom plate 1;

[0042] Rear side plate 2, the lower side of rear side plate 2 and the upper side of bottom plate 1 are vertically integrally connected;

[0043] Left side plate 3, the right side of left side plate 3 and the left side of bottom plate 1 are vertically integrally connected;

[0044] Right side plate 4, the left side of right side plate 4 and the right side of bottom plate 1 are vertically integrally connected;

[0045] First front side plate 51, the upper side of first front side plate 51 and the lower side of left side plate 3 are vertically integrally connected;

[0046] Second front side plate 52, the upper side of second front side plate 52 and the lower side of right side plate 4 are vertically integrally connected, and second front side plate 52 and first front side plate 51 butt joint and form front side plate 5;

[0047] Wherein, rear side plate 2 and front side plate 5 are arranged in parallel, left side plate 3 and right side plate 4 are arranged in parallel, left side plate 3 and right side plate 4 are vertically arranged with rear side plate 2 and front side plate 5, and bottom plate 1, rear side plate 2, left side plate 3, right side plate 4 and front side plate 5 enclose a bottom box.

[0048] ​​The rear side plate 2 has first bending lugs 21 on both sides, which are respectively stopped and clamped on the outer sides of the left side plate 3 and the right side plate 4.

[0049] The left side plate 3 and the right side plate 4 have second bending lugs 31 and third bending lugs 41 respectively at the ends away from the front side plate 5, which are respectively stopped and clamped on the outer sides of the rear side plate 2.

[0050] One side of the first front side plate 51 has a fourth bending lug 511, which is stopped and clamped on the outer side of the second front side plate 52.

[0051] The fourth bending lug 511 has a riveting protrusion 5111 on the side facing the second front side plate 52, and the outer side of the second front side plate 52 has a riveting positioning groove 521, which are riveted and clamped.

[0052] The bottom box can be a cube or a cuboid. When processing, a piece of metal plate is cut into a plate shape as shown in the figure by a wire cutting machine (the bending lugs are not processed in the figure), and then the rear side plate 2 is folded on the bending line 1001 (shown by a dashed line in the figure), the left side plate 3 is folded, the right side plate 4 is folded, and the first front side plate 51 and the second front side plate 52 are folded to form the bottom box. Figure 2 Figure 2

[0053] As can be seen from Figs. 1 to 4, the bottom box is more material-saving when wire cutting, and about 26 grams of material can be saved through rough calculation. If there are 10 million products, about 260 tons of steel can be saved per year. Moreover, the four corners of the bottom box only have gaps 300 at the joint positions of the rear side plate with the left side plate and the right side plate, and have gaps 400 between the front side plate and the bottom plate, which is less than the number of four vertical seams of the existing bottom box bent by a cross plate, so that the overall appearance of the bottom box is better. In addition, the clamping and cooperation of the bending lugs with the corresponding plates, and the riveting clamping and cooperation of the fourth bending lug with the second front side plate through the rivetless riveting process can greatly improve the overall stability of the box body, and can withstand a knocking force of 50N without loosening the bent box body.
