Technical Field

[0001] This utility model relates to the field of wall signage technology, and in particular to a wall signage that is easy to remove and replace quickly. Background Technology

[0002] As society becomes more civilized and service awareness increases, public places are placing greater emphasis on improving their customer service capabilities and providing comprehensive public services. Therefore, communities, shopping malls, supermarkets, exhibitions, and other places where people gather are increasingly equipped with detailed signage, providing various reminders, instructions, and assistance. Conventional signs are typically embedded or fixed to walls, making them difficult to remove or replace.

[0003] An existing patent (publication number: CN214175546U) discloses a detachable signboard, including a base, two support rods, a sleeve, a crossbeam, a handle, and a signboard. The base has a groove, the sleeve includes a sleeve body, a screw, and a connector, and the signboard includes a signboard body, a rubber sleeve, and a sign frame. Pulling the handle moves the crossbeam upwards, causing the sleeve to slide a certain position on the support rods. Rotating the screw fixes the sleeve to the support rods, allowing the crossbeam to slide on the support rods and placing the signboard in the groove. However, this technical solution still has shortcomings, specifically as follows:

[0004] The current device works by rotating a screw to release the crossbeam from its limit position, then pulling the crossbeam to separate it from the sign. Only then can the operator remove the sign, making removal cumbersome. To address this, we propose a wall sign that is easy to remove and replace quickly, solving the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a wall sign that is easy to pull out and replace quickly, which can solve the problem that existing devices require rotating a screw to cause the crossbeam to lose its limit and then pulling the crossbeam to move and separate from the sign, so that the operator can disassemble the sign at this time, which is quite troublesome.

[0007] To solve the above technical problems, this utility model provides a wall sign that is easy to pull out and replace quickly, and adopts the following technical solution: it includes a buffer mechanism, which includes an installation plate, a connecting cylinder is movably inserted into the front side of the installation plate, one end of the connecting cylinder is inserted into the installation plate and a buffer is provided between the connecting cylinder and the installation plate, and an advertising board is fixedly installed at the other end of the connecting cylinder;

[0008] The quick-release mechanism includes two limiting blocks, which are symmetrically arranged on the outer wall of the connecting cylinder. The inner wall of the mounting plate is provided with a multi-functional groove, and the limiting blocks are located in the multi-functional groove and slide in cooperation with the inner wall of the multi-functional groove.

[0009] By adopting the above technical solution, the connecting cylinder is first inserted into the mounting plate and the limiting block is engaged in the multi-functional slot, thereby enabling the connecting cylinder and the advertising board to be installed on the mounting plate. When the advertising board is impacted, the advertising board pushes the connecting cylinder toward the inner wall of the mounting plate. At this time, the buffer is used to cushion the advertising board and the connecting cylinder, thereby reducing the possibility of damage to the advertising board.

[0010] Optionally, the front side of the mounting plate is provided with a mounting groove, and the outer wall of the mounting plate is provided with a plurality of bolt holes.

[0011] By adopting the above technical solution, this solution facilitates the fixing of the mounting plate to the wall through the bolt holes and bolts, and facilitates the assembly of the connecting cylinder and the advertising board through the mounting groove.

[0012] Optionally, a sealing sleeve is fixedly fitted on the outer wall of the connecting cylinder.

[0013] By adopting the above technical solution, this solution uses a sealing sleeve to facilitate an increase in the sealing performance of the connection between the connecting cylinder and the mounting plate.

[0014] Optionally, the buffer includes a first spring and a rubber plate, one end of the first spring being fixedly connected to the inner bottom wall of the mounting groove, and the other end of the first spring being fixedly connected to the rubber plate.

[0015] By adopting the above technical solution, when the advertising board moves the connecting cylinder toward the inner wall of the mounting groove, the connecting cylinder is buffered by the cooperation of the first spring and the rubber plate.

[0016] Optionally, one end of the connecting cylinder inserted into the mounting groove has a circular groove, and the side of the rubber plate away from the first spring abuts against the inner wall of the circular groove.

[0017] By adopting the above technical solution, the rubber plate can be inserted into the connecting cylinder through the circular groove, and the connecting cylinder is buffered by the first spring cooperating with the rubber plate.

[0018] Optionally, the multifunctional groove includes two limiting grooves, two through grooves, and an annular groove. The two limiting grooves and the two through grooves are staggered in the mounting groove, and the two limiting grooves and the two through grooves are connected through the annular groove.

[0019] By adopting the above technical solution, this solution allows the limiting block to be inserted into the installation groove through the through groove, and then move to the annular groove. Then, the advertising board is rotated 90 degrees to make the limiting block coincide with the limiting groove. Then, the advertising board is released, and the rubber plate, connecting cylinder and limiting block are pushed to move by the first spring, thereby making the limiting block move into the limiting groove.

[0020] Optionally, the inner wall of the annular groove is provided with a baffle for blocking the limiting block.

[0021] By adopting the above technical solution, this solution uses a baffle to block the limiting block, so that the operator can only rotate the advertising board and the connecting cylinder by 90 degrees each time.

[0022] Optionally, the front side of the advertising board has two grooves, and scrapers are movably arranged in the two grooves. A screw is rotatably arranged in one of the grooves. One end of the scraper is threaded onto the screw, and one end of the screw passes through the groove, extends out of the advertising board, and is fixedly provided with a control handle.

[0023] By adopting the above technical solution, this solution facilitates the rotation of the screw through the control handle. As the screw rotates, it causes the scraper to move along the inner wall of the groove, thereby scraping the surface of the advertising board.

[0024] In summary, this utility model has at least one of the following beneficial effects:

[0025] When the advertising board needs to be replaced, push the advertising board and the connecting cylinder to move. At this time, the connecting cylinder drives the limit block to move, and then rotates the advertising board 90 degrees, thereby causing the limit block to lose its limit. Then, through the buffer, the connecting cylinder and the limit block are pushed out of the installation plate, making it more convenient to replace the advertising board.

[0026] When the advertising board is impacted, it pushes the connecting cylinder toward the inner wall of the mounting plate. At this time, the buffer cushions the advertising board and the connecting cylinder, thereby reducing the possibility of damage to the advertising board. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0039] Example 1, refer to Figure 1-4 In this embodiment, to address the problem that existing devices require rotating a screw to disengage the crossbeam and then pulling it to separate it from the sign, making sign removal cumbersome for the operator, this invention discloses a wall sign that is easy to quickly remove and replace.

[0040] The system includes a buffer mechanism 100, which includes a mounting plate 101. A connecting cylinder 102 is movably inserted into the front side of the mounting plate 101. A mounting groove 101a is provided on the front side of the mounting plate 101. Several bolt holes 101b are provided on the outer wall of the mounting plate 101. The mounting plate 101 is fixed to the wall by bolts through the bolt holes 101b and bolts. The connecting cylinder 102 is assembled through the mounting groove 101a.

[0041] A sealing sleeve 102a is fixedly fitted on the outer wall of the connecting cylinder 102. The sealing sleeve 102a helps to increase the sealing of the connection between the connecting cylinder 102 and the mounting plate 101, thereby reducing the possibility of foreign objects entering between the connecting cylinder 102 and the mounting plate 101 and jamming the device.

[0042] One end of the connecting cylinder 102 is inserted into the mounting plate 101 and a buffer 103 is provided between them. The other end of the connecting cylinder 102 is fixedly provided with an advertising board 104, which is equipped with a display screen to display information. When the advertising board 104 is impacted, it pushes the connecting cylinder 102 toward the inner wall of the mounting plate 101. At this time, the buffer 103 cushions the advertising board 104 and the connecting cylinder 102, thereby reducing the possibility of damage to the advertising board 104.

[0043] The quick-release mechanism 200 includes two limiting blocks 201 symmetrically arranged on the outer wall of the connecting cylinder 102. A multi-functional groove 202 is formed on the inner wall of the mounting plate 101. The limiting blocks 201 are located within the multi-functional groove 202 and slide against its inner wall. The multi-functional groove 202 includes two limiting grooves 202a, two through grooves 202b, and an annular groove 202c. The two limiting grooves 202a and the two through grooves 202b are staggered within the mounting groove 101a, and are connected to each other via the annular groove 202c. The groove 202b allows the limiting block 201 to be inserted into the mounting groove 101a and then moved into the annular groove 202c. Then, the advertising board 104 is rotated 90 degrees and the limiting block 201 is made to coincide with the limiting groove 202a. The advertising board 104 is then released, and the rubber plate 103b, the connecting cylinder 102 and the limiting block 201 are moved by the first spring 103a, thereby causing the limiting block 201 to move into the limiting groove 202a. Then, the connecting cylinder 102 and the advertising board 104 are installed in the mounting plate 101. Conversely, it is convenient for the operator to disassemble the advertising board 104 and the connecting cylinder 102.

[0044] The inner wall of the annular groove 202c is provided with a baffle 202d for blocking the limiting block 201. The baffle 202d can block the limiting block 201, so that the operator can only rotate the advertising board 104 and the connecting cylinder 102 by 90 degrees each time, thereby increasing the accuracy of the operator when rotating the advertising board 104 and the connecting cylinder 102.

[0045] The specific working principle is as follows: First, insert the connecting cylinder 102 into the mounting plate 101 and cause the limiting block 201 to be inserted into the multi-functional slot 202, thereby causing the connecting cylinder 102 and the advertising board 104 to be installed on the mounting plate 101.

[0046] When the advertising board 104 needs to be replaced, push the advertising board 104 and the connecting cylinder 102 to move. At this time, the connecting cylinder 102 drives the limiting block 201 to move, and then rotates the advertising board 104 ninety degrees, thereby causing the limiting block 201 to lose its limit. Then, through the buffer 103, the connecting cylinder 102 and the limiting block 201 are pushed out of the mounting plate 101, so it is more convenient to replace the advertising board 104.

[0047] Example 2, refer to Figure 2-3 In this embodiment, in order to solve the problem that some existing signs lack a cushioning mechanism when impacted, based on the same concept as in Embodiment 1 above, this wall sign that is easy to quickly remove and replace also includes:

[0048] The buffer 103 includes a first spring 103a and a rubber plate 103b. One end of the first spring 103a is fixedly connected to the inner bottom wall of the mounting groove 101a, and the other end of the first spring 103a is fixedly connected to the rubber plate 103b. When the advertising board 104 drives the connecting cylinder 102 to move toward the inner wall of the mounting groove 101a, the first spring 103a and the rubber plate 103b work together to buffer the connecting cylinder 102, thereby reducing the possibility of damage to the advertising board 104.

[0049] One end of the connecting cylinder 102 inserted into the mounting groove 101a has a circular groove 102b. The side of the rubber plate 103b away from the first spring 103a abuts against the inner wall of the circular groove 102b. The circular groove 102b allows the rubber plate 103b to be inserted into the connecting cylinder 102, and the first spring 103a cooperates with the rubber plate 103b to buffer the connecting cylinder 102.

[0050] The specific working principle is as follows: When the advertising board 104 is impacted, the advertising board 104 pushes the connecting cylinder 102 to move towards the inner wall of the mounting plate 101. At this time, the buffer 103 buffers the advertising board 104 and the connecting cylinder 102, thereby reducing the possibility of damage to the advertising board 104.

[0051] Example 3, referring to Figure 4 Based on the same concept as in Embodiment 1 above, this wall sign that is easy to quickly remove and replace also includes:

[0052] Two grooves 104a are provided on the front side of the advertising board 104. Scrapers 104b are movably arranged in the two grooves 104a. A screw 104c is rotatably arranged in one of the grooves 104a. One end of the scraper 104b is threaded onto the screw 104c. One end of the screw 104c passes through the groove 104a, extends out of the advertising board 104, and is fixedly provided with a control handle 104d.

[0053] The specific working principle is as follows: the control handle 104d facilitates the rotation of the screw 104c. As the screw 104c rotates, the scraper 104b moves along the inner wall of the groove 104a, thereby scraping the surface of the advertising board 104.

[0054] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
