Technical Field

[0001] This utility model belongs to the field of signage technology, and in particular relates to a quick-change content panel mechanism for signage. Background Technology

[0002] A sign typically consists of a panel, a bracket or frame, and fasteners. The panel displays text, symbols, or patterns; the bracket (or frame) supports and secures the panel, while also enhancing the overall aesthetics of the sign; and the fasteners are used to install the sign in the designated location.

[0003] Specifically, the structure of signage may vary depending on the material, size, and application environment. For example, metal signs may be connected to the bracket by welding, riveting, or screws; while plastic signs may be fixed by adhesive or clips.

[0004] However, existing technologies have some problems: traditional signs and brackets are usually fixed by welding, riveting, or screws, which is not conducive to rapid panel replacement. Because the signs are installed at a relatively high position, installation and removal require laying the bracket down or lifting the sign for installation. Therefore, the installation of traditional sign panels is complex and inefficient, easily leading to untimely updates of sign information and further impacting road traffic. Therefore, we propose a mechanism for rapidly changing the content panel of signs. Utility Model Content

[0023] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] like Figures 1 to 6 As shown in the figure, the present invention provides a quick-change content panel mechanism for a sign, including a retaining strip 1 and a connecting seat 2. The retaining strip 1 is fixedly connected to the sign panel. The connecting seat 2 is provided with a clamp 5. There are multiple retaining strips 1. The retaining strip 1 is provided with a sliding groove 11. The connecting seat 2 is provided with a slider 21. The connecting seat 2 is inserted into the retaining strip 1. The slider 21 is slidably connected to the sliding groove 11. The connecting seat 2 is provided with a limiting pin 3. The limiting pin 3 passes through the connecting seat 2. The sliding groove 11 is provided with a limiting hole 12. The limiting pin 3 is inserted into the limiting hole 12. The limiting pin 3 is used to limit the retaining strip 1 and the connecting seat 2.

[0025] Furthermore, the cooperation between the locking strip 1 and the connecting seat 2 enables quick replacement and secure installation of the sign panel. The multiple locking strips 1 enhance the structural strength of the sign panel and make the installation process more flexible. The sliding groove 11 on the locking strip 1 and the slider 21 on the connecting seat 2 slidably connect, greatly simplifying the panel replacement process. Users can easily disassemble and assemble the panel simply by sliding the slider 21, without the need for complex tools or operations. Simultaneously, the insertion design of the limiting pin 3 and the limiting hole 12 provides reliable limiting for the locking strip 1 and the connecting seat 2, ensuring the stability and safety of the sign panel during use. This mechanism not only improves the efficiency of panel replacement but also reduces the difficulty of operation, making the updating of sign content more convenient and faster. In addition, its compact structure and reasonable design make it suitable for various sign scenarios that require frequent content changes, possessing high practical value and promotional significance.

[0026] It should be noted that the clamp 5 is fixedly connected to the bracket, and the clamp 5 and the connecting seat 2 can be tightened to make the panel and the bracket more tightly connected.

[0027] Specifically, the limiting pin 3 is provided with a protruding ball 32. There are multiple protruding balls 32, which are distributed in a circle. The protruding balls 32 are movably connected to the limiting pin 3. The protruding balls 32 can protrude from the surface of the limiting pin 3 and are restricted to move within the limiting pin 3.

[0028] Furthermore, these convex balls 32 are arranged in a circumferential distribution, enhancing the functionality of the limiting pin 3. The convex balls 32 and the limiting pin 3 are connected in a movable manner, allowing the convex balls 32 to freely protrude from the surface of the limiting pin 3 within a certain range. This design enables the convex balls 32 to play a better positioning and locking role when the limiting pin 3 is inserted into the limiting hole 12, effectively preventing accidental loosening between the locking strip 1 and the connecting seat 2. At the same time, the convex balls 32 are restricted to move within the limiting pin 3, ensuring that they can fully perform their function while avoiding damage or failure caused by excessive movement.

[0029] Specifically, the slider 21 is stepped, the slide groove 11 is correspondingly set to the slider 21, the connecting seat 2 has a placement groove 22, the slide groove 11 has a limiting groove 13, and both the placement groove 22 and the limiting groove 13 are corresponding to the convex ball 32.

[0030] Furthermore, the slider 21 adopts a stepped design, closely corresponding to the slide groove 11, ensuring smooth and accurate sliding. A special placement groove 22 is opened inside the connecting seat 2, providing appropriate accommodation space for the stepped part of the slider 21 and enhancing the compactness of the structure.

[0031] Specifically, the limiting pin 3 is provided with a retaining ring 31, the limiting pin 3 has an annular groove 33 inside, the limiting pin 3 has a clearance ring 34 inside, the clearance ring 34 and the annular groove 33 form a hollow area, the limiting pin 3 is provided with a fixing rod 4 inside, the fixing rod 4 is provided with an arc groove 41, the arc groove 41 is correspondingly provided with a convex ball 32, the limiting pin 3 is provided with a fixing block 44, the fixing block 44 is correspondingly provided with the clearance ring 34, and the fixing block 44 is rotatably connected with the annular groove 33.

[0032] Furthermore, an annular groove 33 is formed inside the limiting pin 3, and a clearance ring 34 is configured therein. Together, they form a hollow area, providing ample space for the fixing block 44. Simultaneously, a fixing rod 4 is also provided inside the limiting pin 3, with an arc-shaped groove 41 precisely corresponding to the convex ball 32, ensuring the stability and guidance of the convex ball 32 during movement. In addition, the fixing block 44 on the limiting pin 3 corresponds to the clearance ring 34, and through rotational connection with the annular groove 33, the fixing rod 4 is limited and fixed, further improving the mobility and stability of the convex ball 32.

[0033] Specifically, a pull rod 42 is provided on the fixed rod 4. The pull rod 42 is slidably connected to the limit pin 3. A spring 43 is sleeved on the outside of the limit pin 3. One end of the spring 43 contacts the retaining ring 31, and the other end of the spring 43 contacts the pull rod 42.

[0034] Furthermore, the sliding connection between the pull rod 42 and the limiting pin 3 provides a more direct and effective means of adjusting the convex ball 32. Simultaneously, a spring 43 is cleverly fitted onto the outer side of the limiting pin 3. One end of the spring 43 is tightly against the retaining ring 31, while the other end remains in contact with the pull rod 42. This not only enhances the mechanism's elastic recovery capability but also, after the pull rod 42 is operated, allows the convex ball 32 to more stably engage with the arc-shaped groove 41 through the elastic force of the spring 43. This further improves the stability and reliability of the entire mechanism, providing a stronger guarantee for the rapid replacement and content updating of the sign panel.

[0035] Working principle: During installation, first fix the clip 1 to the nameplate and fix the clamp 5 to the bracket. Then, align the sliding groove 11 on the clip 1 with the slider 21 on the connecting seat 2, insert the clip 1 into the connecting seat 2, rotate the fixing rod 4 to align the fixing block 44 on the fixing rod 4 with the clearance ring 34, pull the pull rod 42, the arc groove 41 on the fixing rod 4 cooperates with the convex ball 32, so that the convex ball 32 retracts into the limit pin 3, thereby releasing the fixation between the limit pin 3 and the connecting seat 2. Insert the limit pin 3 through the connecting seat 2 and into the limit hole 12, release the pull rod 42, the spring 43 resets the fixing rod 4 by elastic force, and pushes the convex ball 32 out of the limit pin 3 through the arc groove 41, so that the convex ball 32 contacts the limit groove 13 to form a fixation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
