Abstract
Description
Technical Field
[0001] This utility model belongs to the field of distribution box technology, and in particular relates to a distribution box with a distribution box mounting bracket. Background Technology
[0002] Distribution boxes, with their advantages of small size, convenient installation, unique technical performance, fixed location, diverse functions, and high space utilization, have been widely used in various fields. Wall-mounted distribution boxes are particularly common, but the need for continuous support during installation places a significant labor burden on installers. To address this, a new type of mounting bracket has emerged to solve the support problem during the installation of wall-mounted distribution boxes, thereby reducing the workload for installers.
[0003] However, although distribution boxes with mounting brackets, as described in announcement number CN217215594U, exist on the market, which use bolts to fix the distribution box to the wall and slide to install it, reducing the time spent lifting the distribution box, the effectiveness of this method is still limited. Because the height at which the distribution box is lifted is not fundamentally changed, the reduction in labor intensity is not significant. More importantly, this sliding connection method makes it difficult to guarantee the connection strength between the distribution box and the mounting wall, easily causing the distribution box to move or shake, increasing safety hazards. Furthermore, the installation process requires precise alignment by the installer, which undoubtedly increases the complexity and difficulty of the installation.
[0004] Therefore, it is essential to invent a distribution box with a distribution box mounting bracket. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a distribution box with a distribution box mounting bracket, including a lifting mounting base, a twisting handle, a distribution box bracket, and a distribution box. Two lifting mounting bases are provided, and the two lifting mounting bases are fixedly connected to the wall by expansion bolts. The two ends of the twisting handle are respectively fixedly connected to the two lifting mounting bases, and the distribution box brackets fixedly installed on the two lifting mounting bases are fixedly connected to the distribution box by bolts.
[0006] The lifting mounting base includes a wall-mounted base, a lifting screw, a lifting seat, a worm gear, a worm, and a side plate. The wall-mounted base is fixedly connected to the wall by expansion bolts. The lifting screw is rotatably installed inside the wall-mounted base. The lifting seat installed on the lifting screw is fixedly connected to the distribution box bracket. One end of the lifting screw, which is rotatably installed inside the wall-mounted base, rotatably protrudes out and is fixedly connected to the worm gear. The worm gear meshes with the worm. The worm is rotatably installed on the side plate fixedly installed at the lower end of the wall-mounted base. The two ends of the toggle handle are respectively fixedly connected to either end of the worm of the two lifting mounting seats.
[0007] Preferably, the distribution box bracket is composed of an L-shaped back plate and two corner plates. The corner plates are fixedly installed on both sides of the included angle of the L-shaped back plate. Numerous mounting holes for the distribution box are provided on the L-shaped back plate and the two corner plates.
[0008] Preferably, the two lifting mounting seats are installed parallel to each other on the wall, and expansion bolts are provided at both ends of the wall-mounted base of the lifting mounting seat to pass through the required through holes. The lifting mounting seat is provided with a U-shaped sliding groove for installing the lifting screw.
[0009] Preferably, the worm gear and worm are located at the lower end of the wall-mounted base, and the lower end of the lifting screw, which is rotatably installed in the U-shaped groove of the wall-mounted base, rotatably protrudes out and is fixedly connected to the worm gear below it.
[0010] Preferably, the side panel is fixedly installed at the lower end of the wall-mounted base in a mirror-symmetrical manner, and the side panel is a "U"-shaped plate.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This invention innovatively improves upon traditional technology by introducing two key components: a lifting mounting base and a distribution box bracket. The lifting mounting base employs an advanced worm gear and screw lifting mechanism, ensuring stable and precise lifting as well as a self-locking function. During installation, the lifting mounting base is first securely fixed to the wall with expansion bolts. Then, the distribution box bracket is lowered to its lowest position, allowing installers to easily place the distribution box onto the bracket. Afterward, the distribution box is simply secured with bolts, and the lifting mounting base is used to raise it to the appropriate installation height. This design cleverly reduces the height the distribution box needs to be lifted during installation, significantly reducing the labor intensity of installers and improving work efficiency. Furthermore, since a sliding connection is no longer used, precise alignment is eliminated during installation, greatly reducing the complexity and difficulty of the installation process, making the entire installation more convenient and efficient.

[0020] As attached Figure 1 To be continued Figure 3 As shown:
[0021] This utility model provides a distribution box with a distribution box mounting bracket, including a lifting mounting base 1, a twisting handle 2, a distribution box bracket 3, and a distribution box 4. Two lifting mounting bases 1 are provided, and the two lifting mounting bases 1 are fixedly connected to the wall by expansion bolts. The two ends of the twisting handle 2 are respectively fixedly connected to the two lifting mounting bases 1. The distribution box brackets 3 fixedly installed on the two lifting mounting bases 1 are fixedly connected to the distribution box 4 by bolts.
[0022] The lifting mounting base 1 includes a wall-mounted base 11, a lifting screw 12, a lifting seat 13, a worm gear 14, a worm 15, and a side plate 16. The wall-mounted base 11 is fixedly connected to the wall by expansion bolts. The lifting screw 12 is rotatably installed inside the wall-mounted base 11. The lifting seat 13, installed on the lifting screw 12, is fixedly connected to the distribution box bracket 3. One end of the lifting screw 12, rotatably installed inside the wall-mounted base 11, rotatably protrudes out and is fixedly connected to the worm gear 14. The worm gear 14 meshes with the worm 15. The worm 15 is rotatably installed on the side plate 16 fixedly installed at the lower end of the wall-mounted base 11. The two ends of the twisting handle 2 are fixedly connected to either end of the worm 15 of the two lifting mounting bases 1. The arrangement of the worm gear 14 and the worm 15 realizes the function of controlling the lifting of the lifting seat 13 by twisting the handle 2, which is simple and convenient to operate.
[0023] Example 1:
[0024] Specifically, the distribution box bracket 3 consists of an L-shaped back plate and two corner plates. The L-shaped back plate, as the main body of the bracket, has its length and width customized according to the dimensions of the distribution box 4, ensuring that the distribution box 4 can be stably placed on the back plate. The two corner plates are fixedly installed on both sides of the included angle of the L-shaped back plate. This design increases the overall stability of the bracket and prevents the distribution box 4 from shaking or tilting during installation. Numerous mounting holes are provided on both the L-shaped back plate and the two corner plates. The position and size of these mounting holes are carefully designed to match the mounting interface of the distribution box 4, allowing the distribution box 4 to be firmly fixed to the bracket with bolts or other fasteners. At the same time, the multiple mounting holes provide more installation options, making the installation of the distribution box 4 more flexible and convenient.
[0025] Specifically, the two lifting mounting bases 1 are installed parallel to each other on the wall, which allows the mounting bases to be firmly fixed to the wall and not easily loosened. Furthermore, a U-shaped groove is cleverly designed on the lifting mounting base 1 for installing the lifting screw 12. The lifting base 13 can slide freely up and down through this U-shaped groove, thereby raising and lowering the distribution box bracket 3 and the distribution box 4 to the appropriate position. This makes the installation and adjustment process simpler and more convenient. Installers only need to pass the expansion bolts through the through holes of the wall-mounted base 11 and fix them to the wall, then install the lifting screw 12 in the U-shaped groove to easily complete the installation of the mounting base. Afterwards, by adjusting the position of the lifting base 13 within the U-shaped groove, the height of the distribution box bracket 3 and the distribution box 4 can be easily controlled to meet different installation needs.
[0026] Specifically, the worm gear 14 and worm 15 are located at the lower end of the wall-mounted base 11. This arrangement not only makes the entire lifting mechanism more compact but also facilitates user operation and maintenance. The lower end of the lifting screw 12 rotates through a U-shaped groove and is cleverly fixedly connected to the worm gear 14. Thus, when the worm 15 rotates, it drives the lifting screw 12 to rotate via the worm gear 14, thereby causing the lifting seat 13 to move up and down. This results in smoother and more precise lifting movements and the ability to withstand larger loads. Simultaneously, this mechanism also has a self-locking function. Furthermore, the location of the worm gear 14 and worm 15 at the lower end of the wall-mounted base 11 also facilitates user operation. Users can simply rotate or twist the handle 2 to drive the worm gear 14 to rotate via the worm 15, thereby controlling the lifting of the lifting seat 13.
[0027] Specifically, the side plate 16 is mirror-symmetrically fixedly installed at the lower end of the wall-mounted base 11, and the side plate 16 is a "U" shaped plate.
[0028] Example 2:
[0029] First, the two lifting mounting seats 1 are securely fixed to the wall using expansion bolts to ensure stability and prevent wobbling. Each lifting mounting seat 1 contains a wall-mounted base 11, within which a lifting screw 12 is rotatably mounted. One end of the lifting screw 12 extends out of the wall-mounted base 11 and is fixedly connected to a worm gear 14, which in turn meshes with a worm 15. The worm 15 is rotatably mounted on a side plate 16 fixedly mounted at the lower end of the wall-mounted base 11. The side plate 16 features a mirror-symmetrical "U"-shaped design, which enhances structural stability and facilitates the installation and fixation of the worm 15. The two ends of the handle 2 are fixedly connected to either end of the worm 15 of the two lifting mounting seats 1. When adjusting the height of the distribution box 4, the user simply rotates the handle 2. The rotation of the handle 2 drives the worm 15 to rotate, and since the worm 15 meshes with the worm gear 14, the rotation of the worm 15 further drives the worm gear 14 to rotate. The worm gear 14 is fixedly connected to the lifting screw 12. Therefore, the rotation of the worm gear 14 will drive the lifting screw 12 to rotate, and the lifting seat 13 installed on the lifting screw 12 will slide up and down within the wall-mounted base 11. The up and down sliding of the lifting seat 13 will drive the distribution box 4 to rise and fall to the appropriate position through the distribution box bracket 3. The design of the distribution box bracket 3 allows the distribution box 4 to be placed stably on it and firmly fixed to the bracket with bolts or other fasteners.
[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
