Description
Technical Field
[0001] The utility model relates to the technical field of traffic speed limit, in particular to a traffic speed limit device for a traffic sign board. Background Technique
[0002] Traffic speed limit signs are a crucial part of road traffic facilities. Traffic speed limit signs provide accurate and timely information and guidance to drivers through different colors and numbers to ensure smooth traffic and driving safety. Its main function is to convey the speed limit information on the road to the driver, ensure that the vehicle travels within a suitable speed range, so as to ensure driving safety and improve road traffic efficiency.
[0003] Existing speed measurement signs are generally installed on both sides of the road or on the top of the road. After being eroded by natural environments such as long-term wind, sun, rain, etc., the surface material of the traffic speed limit sign will gradually age and the color will gradually fade. The aged and faded signboards will become blurred in visual effect, making it difficult for drivers to accurately identify the speed limit information, thereby affecting the control of their driving speed. The blurred signboards will transmit incorrect or ambiguous speed limit signals, thus posing a hidden danger to driving safety. Since the signboard is an integral structure, even if only one sign ages and becomes blurred, the entire signboard needs to be disassembled and replaced. First, it causes a waste of resources. Second, existing signboards are usually fixed with a large number of bolts. When replacing, it is necessary to climb high and use a crane to remove the signboard and replace it with a new one. The replacement time is relatively long and it is easy to block traffic. Therefore, it is urgent to propose a new traffic speed limit device for traffic sign boards to solve the above problems. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the utility model provides a traffic speed limit device for a traffic sign board, which solves the problems that the traffic speed limit sign will age and fade after being eroded for a long time. The aged and faded signboards will become blurred, making it difficult for drivers to accurately identify the speed limit information and affecting the control of their driving speed. Since the signboard is an integral structure, even if only one sign ages and becomes blurred, the entire signboard needs to be disassembled and replaced. First, it causes a waste of resources. Second, existing signboards are usually fixed with a large number of bolts. When replacing, it is necessary to climb high and use a crane to remove the signboard and replace it with a new one. The replacement time is relatively long and it is easy to block traffic.
[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A traffic speed limit device for a traffic sign board includes a speed limit device body, and a plurality of quick replacement mechanisms are arranged on the outer surface of the speed limit device body. The quick replacement mechanism includes a sign board, a push block, a pull rod and a spring;
[0006] The sign is arranged on the front of the speed limit device body. The push block is slidably connected to the outer surface of the speed limit device body. One side of the push block abuts against the sign. The pull rod is fixedly installed on the other side of the push block. The spring is wound around the outer surface of the pull rod.
[0007] For the traffic speed limit device of the traffic sign as described above, preferably, a base is fixedly installed on the front of the speed limit device body, and a top cover is hinged to the top of the base.

[0013] 1. Through the coordinated action of the push block 202, the pull rod 203 and the spring 204, the quick replacement mechanism 2 realizes the quick fixing and replacement of the sign. The user only needs to hold the pull rod 203 and stretch it outwards, the push block 202 slides outwards accordingly, and the spring 204 tightens. At this time, the aging sign 201 can be easily removed. After the positioning block 211 at the bottom of the new sign is snapped into the positioning groove 210, release the pull rod, and the reaction force of the spring will cause the push block and the desiccant box to clamp the sign in the middle of the base together to complete the replacement.
[0014] 2. In order to ensure that the replaced sign is stable and not affected by the external environment, the quick replacement mechanism also designs a sealing structure for the top cover 207 and the base 206.

[0028] By providing a traffic speed limit device for a traffic sign, the embodiment of the present utility model solves the problems that the traffic speed limit sign will age and fade after being eroded for a long time. The aged and faded sign will become blurred, making it difficult for drivers to accurately identify the speed limit information and affecting the control of their driving speed. Since the sign is an integral structure, even if only one sign ages and becomes blurred, the entire sign needs to be disassembled and replaced, which not only causes waste of resources, but also the existing signs are usually fixed with a large number of bolts. When replacing, it is necessary to climb high and use a crane to remove the sign and replace it with a new one. The replacement time is relatively long and it is easy to block traffic.
[0029] In order to better understand the above technical solutions, the following will describe the above technical solutions in detail in conjunction with the drawings of the specification and specific implementation manners.
[0030] According to the attached Figure 1-6 As shown, the embodiment of the present utility model discloses a traffic speed limit device for a traffic sign, which includes a speed limit device body 1. A plurality of quick replacement mechanisms 2 are arranged on the outer surface of the speed limit device body 1. The quick replacement mechanism 2 includes a sign 201, a push block 202, a pull rod 203 and a spring 204;
[0031] When the device is in use, unscrew the fixing bolt 213, hold the fixing block 212 at the end of the top cover 207 and turn it over, hold the pull rod 203 and stretch it outwards. The push block 202 slides outwards accordingly, causing the spring 204 to tighten. Remove the aging sign 201. Insert the positioning block 211 at the bottom of the new sign 201 into the positioning slot 210 in the correct direction to complete the quick positioning of the new sign 201. Release the pull rod 203. Under the reaction force of the spring 204, the push block 202 and the desiccant box 205 clamp the sign 201 in the middle of the base 206. Hold the positioning block 211 at the end of the top cover 207 and turn it over so that the sealing strip 209 is inserted into the sealing groove 208, making the top cover 207 completely enclose the base 206. Screw the fixing bolt 213 into the inside of the fixing block 212 to complete the replacement of the sign 201. The sign 201 is made of plastic. Plastic is lightweight, easy to install and has a low cost. The plastic material can be paired with different reflective strips to make the sign 201 more eye-catching and effectively remind the driver to pay attention to the speed limit.
[0032] Among them, the sign 201 is arranged on the front of the speed limit device body 1. The push block 202 is slidably connected to the outer surface of the speed limit device body 1. One side of the push block 202 abuts against the sign 201. The pull rod 203 is fixedly installed on the other side of the push block 202. The spring 204 is wound around the outer surface of the pull rod 203. One end of the spring 204 is fixedly connected to the push block 202, and the other end is fixedly connected to the base 206 to realize the installation and disassembly of the sign 201.
[0033] In some embodiments, the base 206 is fixedly installed on the front of the speed limit device body 1. The top cover 207 is hinged to the top of the base 206. The material of the top cover 207 is a transparent acrylic plate in the middle, which can clearly and distinctly display the speed limit indication. The outer ring of the transparent acrylic plate is made of an opaque material, so that the internal structure of the quick replacement mechanism 2 cannot be seen from the outside, avoiding distraction of the driver's attention.
[0034] In some embodiments, a desiccant box 205 is fixedly installed on one side inside the base 206. The sign 201 is movably clamped inside the base 206. The other side of the sign 201 abuts against the desiccant box 205. Air holes are formed on the outer surface of the desiccant box 205. By replacing the desiccant inside the desiccant box 205, continuous adsorption of water vapor is achieved, ensuring that there is no water vapor in the quick replacement mechanism 2 to prevent blocking the speed limit sign 201.
[0035] In some embodiments, a sealing groove 208 is formed on the top of the base 206. A sealing strip 209 is fixedly installed at the bottom of the top cover 207. The sealing strip 209 is movably clamped with the sealing groove 208. By using the sealing strip 209 and the sealing groove 208, external water vapor is effectively blocked from entering, so that water does not enter the inside of the quick replacement mechanism 2.
[0036] In some embodiments, a positioning groove 210 is formed inside the base 206, and a positioning block 211 is fixedly installed at the bottom of the sign plate 201. The positioning block 211 is movably clamped inside the positioning groove 210.
[0037] In some embodiments, fixing blocks 212 are fixedly installed at the ends of the base 206 and the top cover 207, and a fixing bolt 213 is threadedly connected between the two groups of fixing blocks 212.
[0038] It can be seen that the traffic speed limit device of the traffic sign provided by the embodiment of the present utility model has the following beneficial effects:
[0039] 1. The quick replacement mechanism 2 realizes the quick fixing and replacement of the sign plate through the coordinated action of the push block 202, the pull rod 203 and the spring 204. The user only needs to grasp the pull rod 203 and stretch it outwards, the push block 202 will slide outwards accordingly, and the spring 204 will contract. At this time, the aging sign plate 201 can be easily removed. After the positioning block 211 at the bottom of the new sign plate is snapped into the positioning groove 210, release the pull rod, and the reaction force of the spring will cause the push block and the desiccant box to clamp the sign plate in the middle of the base together, completing the replacement.
[0040] 2. In order to ensure that the replaced sign plate is stable and not affected by the external environment, the quick replacement mechanism also designs a sealing structure between the top cover 207 and the base 206. The top cover cooperates with the base through flipping, and realizes tight sealing and fixation through structures such as the fixing bolt 213, the fixing block 212, the sealing strip 209 and the sealing groove 208.
[0041] 3. By separating the sign plate from the speed limit device, when the sign plate ages, only the sign plate needs to be replaced, without replacing the whole. And through the sealing mechanism, it is ensured that moisture cannot erode the sign plate, extending the service life of the sign plate. Fixed by a single bolt, it greatly reduces the time required for replacement and improves the efficiency, meeting the needs of users.
