[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-8The utility model discloses an assembled installation backboard, including a backboard 1, an assembly part 2, a mounting box 21 and an explosive expansion screw assembly 22, wherein the assembly part 2 is provided with at least one, and each of the assembly parts 2 includes a mounting box 21 and an explosive expansion screw assembly 22, and the mounting box 21 is connected to the backboard 1; the explosive expansion screw assembly 22 is provided with at least one, and each is connected to the mounting box 21, and is used to be connected to the wall after the explosion is triggered.

[0028] In this embodiment, when the assembly part 2 is provided with one: the assembly box 21 is arranged directly above the back of the back plate 1, so that after the explosive expansion screw assembly 22 is nailed into the wall, the object to be hung on the back plate 1 can be kept horizontal with the viewing horizon. When the assembly part 2 is provided with two: the assembly boxes 21 are arranged on both sides above the back of the back plate 1, so that after the explosive expansion screw assembly 22 is nailed into the wall, the object to be hung on the back plate 1 can be kept horizontal with the viewing horizon, and the force of the explosive expansion screw assembly 22 on the assembly box 21 can be more balanced. When the assembly part 2 is provided with three: the assembly box 21 is arranged in a triangle on the back of the back plate 1, so that after the explosive expansion screw assembly 22 is nailed into the wall, the object to be hung on the back plate 1 can be kept horizontal with the viewing horizon, and the force of the assembly box 21 can be more balanced. When the number of assembly parts 2 is four, the assembly boxes 21 are arranged at the four corners of the back of the back plate 1. Thus, when more and heavier objects need to be hung on the back plate 1, the explosive expansion screw assemblies 22 on the assembly boxes 21 can bear the force more evenly. Moreover, when the objects to be hung on the back plate 1 are too heavy, the number of explosive expansion screw assemblies 22 on each assembly box 21 is set to be multiple, thereby increasing the number of contacts between the explosive expansion screw assemblies 22 and the wall, making the back plate 1 more firmly installed.

[0029] In addition, the explosive expansion screw assembly 22 in the present application is a disposable expansion screw, which can eliminate the need for a nail gun when installing the back panel 1. Since most people now live in cities and the floor area of ​​their homes is relatively limited, the space left for storing installation tools is even more limited. Therefore, equipping the back panel 1 with a disposable expansion screw not only facilitates installation, but also eliminates the need for installation tools. At the same time, labor costs are becoming more and more expensive, and specially inviting a professional installation master to install for a small-scale installation change greatly increases the cost of use. The present application utilizes disposable expansion screws, which can effectively solve the cost problem caused by inviting a professional installation master to install.

[0030] In some embodiments, the explosive expansion screw assembly 22 includes a fixing seat 221, an expansion screw sleeve 222, a limiting sleeve 223, an expansion screw 224, an explosive body 225, a sealing pad 226 and an electric trigger switch 227. The fixing seat 221 has a U-shaped cross section, and the U-shaped fixing seat 221 is clamped with the installation box 21; the expansion screw sleeve 222 is clamped with the inner ring of the fixing seat 221; the limiting sleeve 223 is clamped on the expansion screw sleeve 222; The expansion screw 224 is clamped on the limiting sleeve 223; the explosive body 225 is arranged at the bottom of the U-shaped fixing seat 221, and is used to push the expansion screw 224 during explosion; the sealing gasket 226 is arranged between the explosive body 225 and the expansion screw 224, and is used to store force when the explosive body 225 explodes, and can also be used to prevent the expansion screw 224 from being damaged; the electric trigger switch 227 is arranged in the explosive body 225, and is used to trigger the explosive body 225.

[0031] In this embodiment, the entire material of the fixing seat 221 is explosion-proof steel, so as to prevent the fixing seat 221 from breaking and causing damage to the back plate 1 when the explosive body 225 explodes.

[0032] In addition, since the force released by the explosive body 225 during the explosion is diffuse, a sealing pad 226 is provided between the explosive body 225 and the expansion screw 224. Therefore, when the explosive body 225 explodes, the sealing pad 226 can absorb energy and slide to the side away from the explosive body 225, so that the head of the expansion screw 224 and the sealing pad 226 are in more uniform contact, thereby preventing the expansion screw 224 from being damaged.

[0033] Furthermore, since the explosive expansion screw assembly 22 of the present application is a disposable expansion screw, in order to prevent the explosion of the explosive body 225 due to accidental touch, an electric trigger switch 227 is provided to make the explosion control of the explosive body 225 more accurate.

[0034] Finally, when the explosive expansion screw assembly 22 is needed, the back plate 1 is placed in place, the installation box 21 is placed close to the wall, and the electric trigger switch 227 is pressed to trigger the explosion of the explosive body 225. The explosive force generated by the explosion of the explosive body 225 pushes the sealing pad 226, and the sealing pad 226 pushes the expansion screw 224 into the wall. In this way, the installation of the back plate 1 is achieved.

[0035] In some embodiments, a first limit block 2211 is provided in the middle of the outer side of the U-shaped fixing seat 221, and the first limit block 2211 is clamped on the inner side of the installation box 21; a second limit block 2212 is provided at the opening of the U-shaped fixing seat 221, and the second limit block 2212 is clamped on the outer side of the installation box 21.

[0036] In this embodiment, when the explosive body 225 is not exploded, the head of the expansion screw 224 is close to the bottom of the fixing seat 221, and a plurality of openings are provided on one side of the fixing seat 221 close to the first limit block 2211. Therefore, the fixing seat 221 can be installed on the installation box 21 by pressing the fixing seat 221.

[0037] In addition, a second limiting block 2212 is provided at the opening of the fixing seat 221, and the second limiting block 2212 is also used to limit the expansion screw sleeve 222. The fixing seat 221 is fixed on the installation box 21 more stably through the first limiting block 2211 and the second limiting block 2212.

[0038] Furthermore, a gas hole is provided on the first limit block 2211 for releasing the expansion gas generated by the explosion of the explosive body 225, so as to prevent the fixing seat 221 from being subjected to excessive pressure.

[0039] In some embodiments, a third limit block 2213 is provided on the inner side of the U-shaped fixing seat 221, and the cross-section of the third limit block 2213 is trapezoidal. The limit sleeve 223 abuts against the third limit block 2213, and the third limit block 2213 is used to push the first limit block 2211 against the installation box 21 when the limit sleeve 223 moves toward the direction of the expansion screw sleeve 222.

[0040] In this embodiment, a third limiting block 2213 having a trapezoidal cross section is provided inside the fixing seat 221. After the explosion body 225 explodes, the sealing pad 226 pushes the expansion screw 224 to move, and the expansion screw 224 pushes the limiting sleeve 223 to move. Since the inner diameter of the fixing seat 221 gradually decreases from the inside to the outside, the limiting sleeve 223 will press the third limiting block 2213 after moving, and then the first limiting block 2211 will press the installation box 21, so that after the explosion body 225 explodes, the first limiting block 2211 is more firmly fixed on the installation box 21.

[0041] In some embodiments, a rebound rubber pad 3 is provided between the installation box 21 and the back panel 1 for shock absorption, sound absorption and preventing the back panel from being damaged by collision.

[0042] In this embodiment, since the explosion of the explosive body 225 generates a large impact force, it may cause damage to the back plate 1. Therefore, by providing the rebound rubber pad 3, the damage to the back plate 1 can be effectively avoided. At the same time, since the explosion generates a large noise, by providing the rebound rubber pad 3, the installation noise can also be effectively reduced.

[0043] In some embodiments, a clamping block 11 is provided on the back plate 1 , and a clamping interface 211 is provided on the installation box 21 . The clamping block 11 is clamped with the clamping interface 211 to fix the installation box 21 on the back plate 1 .

[0044] In this embodiment, the mounting box 21 is fixed on the back plate 1 by the clamping block 11 and the clamping interface 211. When the back plate 1 needs to be replaced, it is faster and more convenient. The assembly part 2 can be reused multiple times.

[0045] In some embodiments, the installation box 21 is provided with screw holes 212 for fixing the installation box 21 on the back plate 1 with screws when the back plate 1 is overweight.

[0046] In this embodiment, since some objects are too heavy, it is difficult to firmly fix the back plate 1 by simply clamping, so screw holes 212 are provided on the mounting box 21. Thus, when the back plate 1 is overweight, the mounting box 21 is fixed to the back plate 1 with screws, which can ensure a more stable installation.

[0047] The beneficial effects of the utility model are as follows: by setting a mounting box on the back panel and setting an explosive expansion screw assembly on the mounting box, the back panel can be fixed without using an air nail gun tool. The installation cost is reduced. The problem that the installation of the back panel in the prior art requires inviting a professional installation master to install the back panel, which increases the use cost of the back panel; and the problem that purchasing special installation tools by oneself takes up storage space and wastes the use value of the tools is overcome.
