Description

Technical Field

[0001] The present application relates to the field of signs, and in particular to a fixing structure for a large sign. Background Art

[0002] Common large signs include outdoor billboards and construction site signs, etc. The content of the signs is changed relatively frequently. A large sign includes iron sheets with sign patterns covered thereon. When installing the sign, bolts and nuts are usually used to fix the sign on the frame; when different signs need to be replaced, the fixing points of different signs are also different, and holes need to be drilled again on the frame, which damages the support of the frame and has an adverse impact on the stability of the frame. Content of the Utility Model

[0003] In order to reduce the adverse impact on the stability of the frame, the present application provides a fixing structure for a large sign.

[0004] The fixing structure for a large sign provided by the present application adopts the following technical solution:

[0005] A fixing structure for a large sign is arranged on a frame for installing a sign, and includes a wire mesh fixed on the frame by bolts. A plurality of cylinders are fixedly connected to the surface of the sign without the sign pattern covered thereon. The open ends of the cylinders face away from the sign. When the sign is installed, the positions of the cylinders correspond to the convergence points of the wires of the wire mesh. An opening for the wire to penetrate is formed on the cylinder. A matching column is threadedly connected in the cylinder, and the wire mesh is located between the inner bottom wall of the cylinder and the matching column.

[0006] By adopting the above technical solution, when installing the sign, the operator welds the cylinder at the fixing point of the sign, then aligns the opening of the cylinder with the corresponding wire, and then pushes the sign in the direction close to the wire mesh, so that the wire is inserted into the corresponding opening of the cylinder. Then, the matching column is rotated by a tool, so that the matching column is screwed into the cylinder, and the matching column presses the wire mesh against the inner bottom wall of the cylinder; when disassembling the sign, the matching column is rotated by a tool, so that the matching column is separated from the corresponding cylinder, and thus the sign can be separated from the wire mesh; when replacing different signs, the cooperation of the wire mesh, the cylinder and the matching column reduces the situation of opening holes on the frame, thereby reducing the adverse impact on the stability of the frame.

[0007] Optionally, a special-shaped matching groove is formed on the end face of the matching column away from the sign.

[0008] By adopting the above technical solution, when rotating the matching column, a tool adapted to the matching groove is inserted into the matching groove, and the tool is rotated to rotate the matching column.

[0009] Optionally, the cross-section of the mating groove is hexagonal.

[0010] By adopting the above technical solution, it can be adapted to common screwdrivers.

[0011] Optionally, a hard board is wrapped around the converging point of the iron wires of the wire mesh.

[0012] By adopting the above technical solution, when the mating column and the cylinder clamp the wire mesh, the hard board protects the positions where the wire mesh contacts the mating column and the cylinder, and slows down the wear rate of the wire mesh.

[0013] Optionally, a protective cover is provided on the cylinder, the cylinder and the mating column are located inside the protective cover, and a connecting component for fixing the protective cover and the cylinder is provided on the protective cover.

[0014] By adopting the above technical solution, the protective cover protects the cylinder and the mating column, reduces the entry of rainwater into the position between the cylinder and the mating column, and thus reduces the possibility of rust on the cylinder and the mating column.

[0015] Optionally, at least one installation groove is formed on the inner wall of the protective cover, a connecting block is slidably inserted into the installation groove, a spring is connected to the bottom wall of the installation groove, the spring is fixed to the connecting block, and a connecting groove adapted to the connecting block is formed on the outer wall of the cylinder.

[0016] By adopting the above technical solution, after the mating column is installed in the cylinder, the connecting block is aligned with the connecting groove, then the connecting block is pushed into the connecting groove, and at the same time the connecting block compresses the spring. Then the protective cover is sleeved on the cylinder, the inner wall of the protective cover contacts the outer wall of the cylinder, and the protective cover is pushed towards the direction close to the wire mesh to gradually cover the cylinder. When the installation groove is aligned with the connecting groove, the spring resumes deformation and pushes the connecting block into the connecting groove. When the connecting block abuts against the bottom wall of the connecting groove, the connecting block is partially inserted into the installation groove. At this time, the connecting block cooperates with the installation groove and the connecting groove to fix the protective cover and the cylinder. When the protective cover needs to be pulled out, the protective cover is pulled out of the cylinder, and at this time the connecting block is deformed and damaged, releasing the cooperation with the installation groove and the connecting groove.

[0017] Optionally, the side wall of the connecting block away from the spring is an arc surface, and the side wall of the connecting block away from the spring bends and protrudes away from the spring.

[0018] By adopting the above technical solution, the connecting block can enter the connecting groove better.

[0019] Optionally, a guide rod inserted into the spring is connected to the bottom wall of the installation groove, and a groove adapted to the guide rod is formed on the side wall of the connecting block close to the spring, and the guide rod is inserted into the groove.

[0020] By adopting the above technical solution, the guide rod guides the spring, reducing the occurrence of spring bending.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. By providing the wire mesh, the cylinder, and the mating column, the adverse impact on the stability of the frame is reduced;

[0023] 2. By providing the rigid plate, the rigid plate protects the positions where the wire mesh contacts the mating column and the cylinder, slowing down the wear rate of the wire mesh;

[0024] 3. By providing the protective cover, the installation groove, the connecting block, the spring, and the connecting groove, the possibility of rusting of the cylinder and the mating column is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0031] An embodiment of the present application discloses a fixing structure for a large signboard.

[0032] Embodiment 1

[0033] Refer to Figure 1 and Figure 2 , which is arranged on the frame 2 for installing the signboard 1; the fixing structure includes a wire mesh 3 fixed to the frame 2 by bolts, refer to Figure 2 and Figure 3, a plurality of cylinders 4 are fixedly connected to the surface of the signboard 1 that is not covered with a sign pattern, and the openings of the cylinders 4 face away from the signboard 1; when the signboard 1 is installed, the positions of the cylinders 4 will correspond to the wire convergence points of the wire mesh 3, and each cylinder 4 is provided with a notch for the wire to penetrate.

[0034] A mating post 5 is threadedly connected in the cylinder 4, and a special-shaped mating groove 51 is formed on the end surface of the mating post 5 away from the signboard 1. When installing or disassembling the signboard 1, an operator can insert a suitable screwdriver into the mating groove 51 and turn the screwdriver to screw the mating post 5; in this embodiment, the cross-section of the mating groove 51 is hexagonal, which can be adapted to common screwdrivers, thus facilitating the operator to turn.

[0035] When installing the signboard 1, the operator first welds the cylinder 4 to the fixed point of the signboard 1, then aligns the notch of the cylinder 4 with the corresponding wire, pushes the signboard 1 to insert the wire into the notch of the cylinder 4, and then uses a tool to turn the mating post 5 to screw it into the cylinder 4, so as to press the wire mesh 3 against the inner bottom wall of the cylinder 4. The disassembly process is the opposite. First, turn the mating post 5 to separate it from the cylinder 4, and then the signboard 1 can be separated from the wire mesh 3. When replacing different signboards 1, the wire mesh 3, the cylinder 4 and the mating post 5 cooperate to adapt to different fixed points of different signboards 1, reducing the need to open holes in the frame 2, thereby reducing the adverse impact on the stability of the frame 2.

[0036] In order to slow down the wear rate of the wire mesh 3, a hard board 31 is wrapped around the wire convergence point of the wire mesh 3. The hard board 31 can protect the positions where the wire mesh 3 contacts the mating post 5 and the cylinder 4 when the mating post 5 and the cylinder 4 clamp the wire mesh 3, thereby slowing down the wear rate of the wire mesh 3 and extending the service life of the wire mesh 3.

[0037] The implementation principle of Embodiment 1 of this application is: weld the cylinder 4 at the fixed point of the signboard 1, then cooperate the signboard 1 with the wire mesh 3, insert the wire of the wire mesh 3 into the notch of the cylinder 4, turn the mating post 5 to make the mating post 5 threadedly cooperate with the cylinder 4 until the mating post 5 cooperates with the inner bottom wall of the cylinder 4 to clamp the hard board 31; when disassembling the signboard 1, turn the mating post 5 until the mating post 5 disengages from the cylinder 4, and at this time the iron plate is separated from the wire mesh 3, and the signboard 1 can be removed from the wire mesh 3.

[0038] Embodiment 2

[0039] Refer to Figure 4, in this embodiment, a protective cover 6 for protecting the cylinder body 4 and the mating column 5 is added on the basis of Embodiment 1. The opening of the protective cover 6 faces the signboard 1, and a connecting component 7 is also provided on the protective cover 6; the connecting component 7 connects and fixes the protective cover 6 to the cylinder body 4, so that the cylinder body 4 and the mating column 5 are located in the protective cover 6. At this time, the outer wall of the cylinder body 4 contacts the inner wall of the protective cover 6. The protective cover 6 reduces the situation of rainwater seeping between the cylinder body 4 and the mating column 5, thereby reducing the occurrence of rust on the mating column 5 and the cylinder body 4.

[0040] At least one installation groove 61 is formed on the inner wall of the protective cover 6. In this embodiment, the number of installation grooves 61 is two. The connecting component 7 includes a connecting block 71 slidably inserted into the installation groove 61. In this embodiment, the side wall of the connecting block 71 away from the bottom wall of the installation groove 61 is an arc surface, and the side wall of the connecting block 71 away from the bottom wall of the installation groove 61 bends towards the outside of the installation groove 61; a spring 72 is connected to the bottom wall of the installation groove 61, one end of the spring 72 is fixed to the connecting block 71, and connecting grooves 41 corresponding to the connecting blocks 71 one by one are formed on the outer wall of the cylinder body 4. Since the side wall of the connecting block 71 away from the bottom wall of the installation groove 61 is an arc surface, the connecting block 71 can enter the connecting groove 41 more smoothly.

[0041] A guide rod 73 inserted into the spring 72 is also fixedly connected to the bottom wall of the installation groove 61, and a groove 711 adapted to the guide rod 73 is formed on the side wall of the connecting block 71 close to the spring 72; one end of the guide rod 73 is inserted into the groove 711, and the guide rod 73 can guide the spring 72, thereby reducing the occurrence of the spring 72 bending.

[0042] After the mating column 5 is installed in the cylinder body 4, the operator aligns the connecting block 71 with the connecting groove 41 and pushes the connecting block 71 to move into the connecting groove 41. At the same time, the connecting block 71 compresses the spring 72. Then, the protective cover 6 is sleeved on the cylinder body 4 so that the inner wall of the protective cover 6 contacts the outer wall of the cylinder body 4. Then, the protective cover 6 is pushed in the direction close to the wire mesh 3 to gradually cover the cylinder body 4.

[0043] When the installation groove 61 is aligned with the connecting groove 41, the spring 72 resumes deformation and pushes the connecting block 71 to move into the connecting groove 41. When the connecting block 71 abuts against the bottom wall of the connecting groove 41, the connecting block 71 is partially inserted into the installation groove 61. At this time, the connecting block 71, the installation groove 61 and the connecting groove 41 cooperate to fix the protective cover 6 to the cylinder body 4; when the protective cover 6 needs to be pulled out, only the protective cover 6 needs to be pulled out of the cylinder body 4. During this process, the connecting block 71 will be deformed and damaged, thereby releasing the cooperation with the installation groove 61 and the connecting groove 41.

[0044] The implementation principle of Embodiment 2 of this application is as follows: After screwing the mating column 5 into the cylinder body 4, push the connecting block 71 into the installation groove 61 and align the connecting block 71 with the connecting groove 41. Then move the protective cover 6 so that the protective cover 6 is sleeved on the cylinder body 4. When the protective cover 6 is moved in place, the spring 72 resumes deformation and pushes the connecting block 71 into the connecting groove 41, and the connecting block 71 fixes the protective cover 6 and the cylinder body 4; when it is necessary to remove the protective cover 6, pull the protective cover 6 until the protective cover 6 is separated from the cylinder body 4.

[0045] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
