[0002] In various public places, various types of advertising screens are needed for advertising or policy promotion. In order to avoid taking up space, the aforementioned advertising screens are generally wall-mounted. The conventional arrangement is to set up a support frame for fixing the advertising screen near the socket, and then fix the support frame to the advertising screen. After the advertising screen is disassembled, the socket hole will be left and the wall surface will need to be filled and repaired. Utility Model Content
[0003] To address the issue of needing additional sockets for fixing the advertising screen, this utility model provides a wall-mounted advertising screen.
[0004] The technical solution of this utility model is as follows:
[0005] A wall-mounted advertising screen includes a screen body and a junction box body that can be detachably fixed to the wall;
[0006] The junction box body includes a mounting frame inserted into a wall groove, and the mounting frame is symmetrically provided with horizontal limiting plates at positions relative to the outer edge of the wall, and a horizontal support frame is provided transversely between the limiting plates, the horizontal support frame can only move along the length direction.
[0007] The horizontal support frame has symmetrically arranged positioning cylinders at both ends, and the positioning cylinders are vertically inserted with insertion rods, which can only move upward relative to the positioning cylinders;
[0008] A connector frame is provided in the middle of the back panel of the screen body, and the connector frame is configured in conjunction with the plug rod.
[0009] Unlike conventional methods, this design integrates the socket with the support frame structure for fixing the advertising screen, giving it the function of fixing the advertising screen. Furthermore, some parts of the structure can be disassembled, allowing it to still be used as a socket after the advertising screen is removed.
[0010] To facilitate wiring, the junction box body also includes wiring sections symmetrically arranged above and below the symmetrical lines of the limiting plate.
[0011] The mounting frame is fixed by having multiple insertion holes between the limiting plates, and expansion bolts installed in the insertion holes. The expansion bolts are installed in the countersunk holes and their ends do not extend outward.
[0012] To facilitate the assembly and disassembly of the screen body, the back panel of the screen body is symmetrically provided with grips about the vertical center line.
[0013] In order to fix the position of the horizontal support frame, the mounting frame is provided with insertion holes between the limiting plates, and the horizontal support frame can be inserted into the insertion holes by means of a pin when it is in the center position.
[0014] To facilitate insertion, the ends of the horizontal support frame are chamfered.
[0015] To facilitate the installation of the screen body, the upper end of the insertion rod is chamfered.
[0016] As a preferred embodiment, the height of the positioning cylinder is less than the distance between the two limiting plates.
[0017] To facilitate the insertion connection, the positioning cylinder is positioned on the surface of the horizontal support frame away from the wall.
[0018] The specific structure of the aforementioned insertion rod is as follows: the insertion rod includes a cylinder and a collar integrally formed on the outer side of the cylinder.
[0019] The beneficial effects of this utility model are as follows: This utility model is a wall-mounted advertising screen. Unlike the conventional method of setting up a mounting bracket by opening a hole near the socket, this device integrates the mounting bracket and the socket. The resulting junction box body not only has the function of a socket, but can also be connected to a horizontal support frame and a plug rod to connect with the screen body. In this way, the function of the junction box body can be freely selected according to the needs, and even if the advertising screen is not needed later, it can still be used as a junction box normally.

[0028] Example
[0029] A wall-mounted advertising screen, including such as Figure 1 The screen body 1 shown and the screen that can be detachably fixed to the wall are shown. Figure 2 As shown in the junction box body 2, unlike the conventional method of opening mounting holes and setting mounting brackets next to the junction box socket, the junction box body 2 of this device can be used for both power supply wiring and mounting the screen body 1.
[0030] And such as Figure 2-4 As shown, the junction box body 2 includes a mounting frame 21 inserted into a wall recess. The mounting frame 21 is rectangular, and horizontal limiting plates 24 are symmetrically arranged vertically on the mounting frame 21 relative to the outer edge of the wall. There is a gap between the two limiting plates 24, and both limiting plates 24 are bent. The purpose is to allow a transverse support frame 3 to be arranged horizontally through the limiting plates 24, and the transverse support frame 3 can only move along the length direction, i.e. Figure 3 As shown, this method enables the plug-in installation of the horizontal support frame 3, and it can also be disassembled when necessary to avoid affecting the normal use of the junction box body 2.
[0031] Furthermore, in the above structure, in order to facilitate insertion, the end of the horizontal support frame 3 is provided with a chamfer. The chamfer makes it easy to insert one end of the horizontal support frame 3 between the two limiting plates 24.
[0032] Furthermore, it should be noted that if there is a requirement for positional limitation, i.e., in order to fix the position of the horizontal support frame 3, the mounting frame 21 is provided with insertion holes between the limiting plates 24. The horizontal support frame 3 can be inserted into the insertion holes by means of a pin when it is in the center position. After the pin is inserted, the horizontal support frame 3 can be prevented from changing position. After the screen body 1 is installed, its position can be ensured to be more stable and there will be no displacement.
[0033] Furthermore, the specific method is as follows: Figure 4 As shown, positioning cylinders 32 are symmetrically arranged at both ends of the horizontal support frame 3. In order to ensure the normal installation of the horizontal support frame 3, the height of the positioning cylinder 32 is less than the distance between the two limiting plates 24. In this way, the positioning cylinder 32 can be directly integrally formed with the horizontal support frame 3, which is more convenient during installation.
[0034] Finally, there is the structure for inserting the screen body 1, namely, the positioning cylinder 32 is vertically inserted with the insertion rod 4. The insertion rod 4 can only move upward relative to the positioning cylinder 32, thus ensuring that the insertion bracket 13 of the screen body 1 can remain stable after being inserted from above, and can only be disassembled after the staff removes it from above.
[0035] Therefore, such as Figure 1 As shown, a connector 13 is provided in the middle of the back plate 11 of the screen body 1, and the connector 13 is configured to cooperate with the plug rod 4.
[0036] The above method can achieve the desired result. Unlike conventional methods, the socket and the support frame structure for fixing the advertising screen are integrated into one. During installation, the main body 2 of the junction box can not only be used for wiring, but also for fixing the advertising screen. By enabling it to fix the advertising screen, and with some parts of the structure being detachable, it can still be used as a socket after the advertising screen is removed.
[0037] In the above structure, in order to facilitate wiring, the junction box body 2 also includes wiring portions 22 symmetrically arranged above and below the symmetrical line of the limiting plate 24. When in use, the upper wiring portion 22 is blocked by the screen body 1, and the lower wiring portion 22 can be used.
[0038] The mounting frame 21 is fixed by having multiple insertion holes between the limiting plates 24, and expansion bolts 23 are installed in the insertion holes. The expansion bolts 23 are installed in the countersunk holes and their ends do not extend outward. In this way, the frame does not extend outward from the wall, thus ensuring greater stability after the screen body 1 is installed, and preventing it from protruding too much and taking up more space.
[0039] Furthermore, to facilitate the assembly and disassembly of the screen body 1, the back plate 11 of the screen body 1 is symmetrically provided with grips 12 about the vertical center line. In use, the operator can lift the screen body 1 by holding the grips 12 with both hands and then install it.
[0040] Furthermore, since the aforementioned insertion method requires alignment with the center of the insertion rod 4, the upper end of the insertion rod 4 is chamfered to facilitate the installation of the screen body 1. The specific structure of the insertion rod 4 is as follows: the insertion rod 4 includes a cylinder and a collar integrally formed on the outer side of the cylinder. The collar prevents it from passing through the positioning cylinder 32 and also supports the screen body 1.
[0041] Finally, to facilitate the insertion connection, the positioning cylinder 32 is set on the surface of the horizontal support frame 3 facing away from the wall.
