Description

Technical Field

[0001] The utility model belongs to the technical field of wall-mounted anti-falling, and particularly relates to an anti-falling hanging piece and a blackboard installation assembly. Background Art

[0002] At present, the installation of the blackboard 2 on the wall 4 is mostly carried out by using "L"-shaped mounting parts 3 at the upper and lower parts of the blackboard 2 respectively. The vertical part of the mounting part 3 is pre-installed on the wall 4 by nails or expansion bolts, and the upper and lower parts of the blackboard 2 are respectively connected to the horizontal parts of the corresponding mounting parts 3 by self-tapping screws, so as to realize the installation of the blackboard 2 on the wall (specifically as Figures 1-4 shown). However, the outer frame 22 of the blackboard 2 is generally made of an aluminum alloy profile structure, with a relatively thin wall thickness and relatively low material hardness. When the self-tapping screw is connected to the outer frame of the blackboard, it is usually not firm enough. Moreover, most of the current blackboards 2 are combined blackboards, with a large area and weight. During use, pushing and pulling the blackboard also generates impact vibrations, etc., which easily causes the screws to loosen. In severe cases, the blackboard 2 may fall off, easily resulting in safety accidents. Summary of the Utility Model

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide an anti-falling hanging piece with a simple structure, which can be installed on a vertical wall to provide anti-falling protection for the hanging object installed on the vertical wall.

[0038] As Figure 5 And Figure 6As shown, this embodiment provides an anti-falling pendant, including a hook plate 11, a fixing member 12 and a hanging member 13, one side of the hook plate 11 has a hook 111 with a hook mouth facing upward, the fixing member 12 is used to fix the hook plate 11 on the vertical wall, one side of the hanging member 13 has a barb, and the hook mouth of the barb faces downward, the barb of the hanging member 13 is hung with the hook 111, and the hanging member 13 is used to connect with the hanging object, so that after the hanging object is pre-installed on the vertical wall, the hook plate can be installed on the vertical wall through the fixing member and located above the hanging object, and then the hanging member is hung on the hook plate, and then the hanging member is connected to the hanging object, so that the anti-falling pendant can perform anti-falling treatment on the hanging object.

[0039] See Figure 5 As shown, the above technical solution also includes a connecting ring rope 14, the fixing member 12 has a first connecting portion connected to the connecting ring rope 14, and the upper end of the hanging member 13 has a second connecting portion connected to the connecting ring rope 14, so that the hanging member can be connected to the fixing member through the connecting ring rope, which can further prevent the hook plate and the hanging member from loosening and causing the hanging object to fall, and the connection ring rope can play a double anti-falling role.

[0040] See Figure 5 and Figure 6 As shown, the hook plate 11 in the above technical solution is a "J"-shaped plate, and a mounting hole 112 is provided at the upper end of the hook plate 11 for the fixing member 12 to vertically pass through. It has a simple structure and is easy to install on the vertical wall, especially the side away from the hook can be in contact with the vertical wall, so that the installation effect on the vertical wall is better.

[0041] See Figure 5 and Figure 6As shown, in the above technical solution, the fixing member 12 includes an expansion bolt 121 and a first nut 122. An end portion of the threaded end of the expansion bolt 121 is provided with a first connection hole 1211 in the radial direction.

For the installation of the connecting cable, after the first nut on the middle expansion bolt is tightened until the expansion bolt expands and gets stuck and fastened with the hole in the wall, the first nut can be unscrewed to completely expose the second connecting hole for the connecting cable to pass through, and the first nuts are tightly installed on the other two expansion bolts.

[0048] In this embodiment, the hanging object can be a blackboard, a picture frame, or a relatively large - area publicity board, etc.

[0049] Embodiment 2

[0050] As Figures 7-10 shown, this embodiment provides a blackboard installation assembly, which includes a blackboard 2, a plurality of mounting members 3, and the anti - falling hanging member 1 as described in Embodiment 1. The blackboard 2 is installed on the wall 4 through the plurality of mounting members 3. The anti - falling hanging member 1 is installed on the wall 4 and is connected to the upper end of the blackboard 2. The wall 4 constitutes the vertical wall, and the blackboard 2 constitutes the hanging object. Its structure is simple. In this way, after the blackboard is installed on the wall through the mounting members, it is then connected to the anti - falling hanging member installed on the wall, so as to prevent the blackboard from loosening from the mounting members and falling.

[0051] As Figures 1-4As shown, in the above technical solution, the mounting member 3 is in an "L" shape. A plurality of the mounting members 3 are respectively arranged at the upper end and the lower end of the blackboard 2, and the horizontal parts of the mounting members 3 are respectively connected to the blackboard 2, and the vertical parts of the mounting members 3 are connected to the wall 4. In this way, the installation effect of the blackboard on the wall through a plurality of mounting members is good; specifically, four mounting members can be provided, and two of the mounting members are respectively installed at intervals along the length direction at the upper end and the lower end of the blackboard. The installation of the blackboard on the wall through the mounting members belongs to the existing installation structure, and in this embodiment, an anti-falling hanging member is added to be connected to the wall on the existing installation structure of the blackboard, so that the blackboard will not fall and hit people after being loosened from the mounting members.

[0052] See Figure 7 As shown, in this embodiment, the anti-falling hanging member can be installed in the middle of the upper end of the blackboard (this makes the balance of the left and right ends of the blackboard good). Since the upper end of the blackboard extends into the second groove connection part, after all the mounting members on the blackboard are loosened, it will not tilt under the hanging connection of the anti-falling hanging member. The bottom wall of the second groove connection part can limit the swinging angle of the blackboard relative to the connecting member (of course, if there are multiple connecting members, there is no need to worry about the problem that the blackboard will tilt when it is loosened from all the mounting members).

[0053] Such as Figures 8-10 As shown, in this embodiment, a hanging hole 21 for the connecting member 132 to pass through is provided in the middle of the upper end of the blackboard (the hanging hole is arranged on the outer frame 22 at the corresponding position of the blackboard), and the number of the hanging holes 21 is the same as the number of the connecting members 132.

[0054] The above is only the preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention; any ordinary technical personnel in the industry can smoothly implement the present invention according to the description shown in the accompanying drawings of the specification and the above description; however, any slight changes, modifications and evolutions made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
