Description

Technical Field

[0001] This utility model belongs to the field of road sign technology, specifically a road sign with quickly replaceable sign content. Background Technology

[0002] Road signs are road facilities that use graphic symbols, colors, and text to convey guidance, restrictions, warnings, or instructions to road users. They are characterized by safety, visibility, and clarity, and play a vital role in managing traffic, ensuring road safety, and facilitating smooth vehicle passage.

[0003] Patent CN221297657U discloses a road sign, including a fixed riser with a support rod movably connected inside. The support rod is detachably connected to the fixed riser via a positioning component. A connecting frame is provided on the outer wall of the support rod, and the connecting frame includes two annular fixing seats. A fixed vertical plate is connected to the outer walls of the two annular fixing seats. A second rectangular horizontal bar is provided in the middle of the left side of the fixed vertical plate. A sign is detachably connected to the connecting frame via the fixing component. This road sign uses a second fastening bolt to fix the second rectangular tube to the second rectangular horizontal bar, thus allowing the sign to be installed on the connecting frame, facilitating quick installation by workers. When disassembling the sign, the positioning component is disassembled, causing the support rod to move downwards, with most of the support rod retracting into the fixed riser, lowering the sign to a height that workers can easily disassemble without the need for climbing equipment, allowing workers to perform disassembly and assembly operations from the ground.

[0004] However, the aforementioned type of road sign still has the following shortcomings: The above-mentioned device fixes the second rectangular tube to the second rectangular crossbar with the second fastening bolt, thereby installing the sign on the connecting frame. However, this process requires workers to frequently tighten the bolts, which is time-consuming and labor-intensive. Therefore, we propose a road sign that can quickly change the content of the sign. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a road sign with quickly replaceable sign content, which effectively solves the problem that the existing device fixes the second rectangular tube to the second rectangular crossbar by the second fastening bolt, so that the sign can be installed on the connecting frame. However, this process requires workers to frequently tighten the bolts, which is time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a road sign with quickly replaceable sign content, comprising a positioning pole, an adjusting support mechanism provided at the middle of the positioning pole, a sign body attached to the surface of the adjusting support mechanism, a set of inserts symmetrically fixed to the rear side of the sign body, a limiting mechanism provided on the side of the adjusting support mechanism away from the sign body, the limiting mechanism comprising a cylindrical frame, a set of cylindrical frames symmetrically fixed to the surface of the adjusting support mechanism, a set of limiting rods symmetrically inserted inside the set of cylindrical frames, a limiting ring plate fixedly sleeved on the surface of the limiting rods, a spring provided on one side of the limiting ring plate, and a pull rod fixedly connected to the inner side of the bottom of the upper limiting rod.

[0007] Preferably, the limiting rod is formed into an elastic structure by a limiting ring plate, a spring and a cylindrical frame, and the surface of the insert is provided with a limiting groove that matches the end of the limiting rod.

[0008] Preferably, the upper limiting rod is Z-shaped, and the upper limiting rod and the lower limiting rod form an engaging sliding structure through a pull rod.

[0009] Preferably, the adjusting support mechanism includes positive and negative lead screws, which are locked inside the middle of the positioning column. A throttle is fixed to the top of the positive and negative lead screws. A set of brackets is symmetrically sleeved on the surface of the positive and negative lead screws. An auxiliary frame is fixed to the bottom of the brackets. Folded protective covers are glued to the upper and lower surfaces of the brackets.

[0010] Preferably, the bracket and the positive and negative lead screws are connected by threads, the bracket and the auxiliary frame form a right-angled triangle structure, and one side of the auxiliary frame is matched and attached to the surface of the positioning column.

[0011] Preferably, the folding protective cover, in conjunction with the bracket, can shield the groove on the surface of the positioning pole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By utilizing the elastic structure formed by the limiting rod and the limiting ring plate and the spring within the cylindrical frame, the end of the limiting rod can be quickly engaged or disengaged from the limiting groove on the surface of the insert, enabling rapid installation and disassembly of the sign body. The upper limiting rod, through the engaging and sliding structure formed by the pull rod and the lower limiting rod, can effectively connect a set of limiting rods without affecting the movement of a set of limiting rods along with a set of brackets.

[0013] 2. Through the threaded connection between the positive and negative screws and the brackets, the operator only needs to turn the handle to drive the upper and lower brackets to move synchronously in opposite directions along the positive and negative screws, thereby conveniently adjusting the spacing of the brackets to adapt to different sizes of sign bodies, greatly improving the compatibility of the device with diverse sign specifications. The right-angled triangular structure formed by the brackets and auxiliary frame, with the stability characteristics of triangles, can effectively enhance the support strength of the brackets for the sign body. Combined with the fit design of the auxiliary frame and the positioning pole surface, the stress is further distributed. The folding protective cover bonded to the upper and lower surfaces of the brackets can extend and retract synchronously with the movement of the brackets, effectively blocking the grooves on the surface of the positioning pole, preventing rainwater, dust and other impurities from entering the positioning pole and causing parts to rust or become blocked, thus extending the service life of the device.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4A road sign with quickly changeable signage content includes a positioning pole 1. An adjusting support mechanism 2 is located at the center of the positioning pole 1. A sign body 3 is attached to the surface of the adjusting support mechanism 2. A set of inserts 4 are symmetrically fixed to the rear side of the sign body 3. A limiting mechanism 5 is located on the side of the adjusting support mechanism 2 away from the sign body 3. The limiting mechanism 5 includes a cylindrical frame 501. A set of cylindrical frames 501 are symmetrically fixed to the surface of the adjusting support mechanism 2. A set of limiting rods 502 are symmetrically inserted into the cylindrical frames 501. A limiting ring plate 503 is fixedly sleeved on the surface of the limiting rods 502. A spring 504 is located on one side of the limiting ring plate 503. The limiting rods 502, through the limiting ring plate 503 and the spring 504, form an elastic structure with the cylindrical frame 501. The inserts 4 have an open surface. A limiting groove matching the end of the limiting rod 502 is provided. A pull rod 505 is fixedly connected to the inner bottom of the upper limiting rod 502. Furthermore, the upper limiting rod 502 is Z-shaped. The upper limiting rod 502 and the lower limiting rod 502 form a locking and sliding structure through the pull rod 505. By utilizing the elastic structure formed by the limiting ring plate 503 and the spring 504 within the cylinder frame 501, the end of the limiting rod 502 can be quickly locked into or pulled out of the limiting groove on the surface of the insert 4, realizing the rapid installation and disassembly of the sign body 3. The locking and sliding structure formed by the upper limiting rod 502 and the lower limiting rod 502 through the pull rod 505 can effectively connect a set of limiting rods 502 without affecting the movement of a set of limiting rods 502 with a set of brackets 203.

[0019] The adjusting support mechanism 2 includes a positive and negative lead screw 201, which is locked inside the middle of the positioning rod 1. A handle 202 is fixedly connected to the top of the positive and negative lead screw 201. A set of brackets 203 are symmetrically fitted on the upper and lower surfaces of the positive and negative lead screw 201. An auxiliary frame 204 is fixed to the bottom of the brackets 203. The brackets 203 and the positive and negative lead screw 201 are threadedly connected. The brackets 203 and the auxiliary frame 204 form a right-angled triangle structure. One side of the auxiliary frame 204 is fitted to the surface of the positioning rod 1. Folded protective covers 205 are glued to both the upper and lower surfaces of the brackets 203. Furthermore, the folded protective covers 205 cooperate with the brackets 203 to cover the groove on the surface of the positioning rod 1. Through the threaded connection between the positive and negative lead screw 201 and the brackets 203, the operator only needs to turn the handle 202. This allows the upper and lower sets of brackets 203 to move synchronously in opposite directions along the forward and reverse screws 201, thereby facilitating the adjustment of the spacing between the brackets 203 to accommodate different sizes of sign bodies 3. This significantly improves the device's compatibility with diverse sign specifications. The right-angled triangular structure formed by the brackets 203 and the auxiliary frame 204, leveraging the stability of triangles, effectively enhances the support strength of the brackets 203 for the sign body 3. Combined with the fitting design of the auxiliary frame 204 and the positioning pole 1, the stress is further distributed. The folding protective covers 205 bonded to the upper and lower surfaces of the brackets 203 can extend and retract synchronously with the movement of the brackets 203, effectively shielding the grooves on the surface of the positioning pole 1. This prevents rainwater, dust, and other impurities from entering the positioning pole 1 and causing corrosion or blockage of components, thus extending the service life of the device.
