Description

Technical Field

[0001] This utility model relates to the field of road marking and signage technology, and in particular to a road marking and signage component that can be quickly replaced. Background Technology

[0002] With rapid economic development and accelerated urbanization, road traffic flow is constantly increasing, and the requirements for the precision of traffic management are becoming increasingly higher. In order to better guide traffic, ensure traffic safety, and improve road traffic efficiency, a more flexible and efficient road marking and signage system is needed to adapt to the ever-changing traffic conditions. For example, after the development of new urban areas or the construction of large commercial centers, the traffic flow and volume of surrounding roads change, and road markings and signs need to be adjusted in a timely manner.

[0003] Existing technologies, such as the utility model with publication number CN212956213U, disclose a fluorescent road sign and marking device. This patent uses a front support plate and a rear support plate, which are movably connected by a pivot. A buckle plate is movably connected to the lower part of the front support plate, and a metal sheet is provided on the front surface. The metal sheet has a magnet. A storage compartment is provided in the middle of the inner side of the rear support plate. This utility model's fluorescent road sign and marking device facilitates the temporary replacement of signs through the design of fluorescent sign magnets. The storage compartment in the rear support plate allows for the storage of multiple signs, making them easy to retrieve and use when needed. A buckle plate is also provided to secure the folded front and rear panels. Combined with the carrying slot on the upper part of the support plate, the device can be carried and transferred, improving its flexibility. The bottom rubber pad provides greater stability, allowing it to be used in more complex environments. This addresses the increasing demand for road sign and marking devices in various locations, including residential areas, parking lots, and construction sites, which necessitates greater flexibility.

[0004] In the daily use of road sign components, there are existing road sign components, such as the one mentioned above, that are fixed by magnetic attraction. However, in outdoor environments, the magnets may lose their magnetism, causing the fluorescent signs to fall off. Once they fall off, the originally clear directional information becomes incomplete, which may cause road users such as drivers, pedestrians, or people inside buildings to misunderstand. This could lead to people losing their way due to a lack of proper guidance in emergency situations, increasing the risk of danger. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing road marking components are fixed by magnetic attraction, but in outdoor environments, the magnet may lose its magnetism, causing the fluorescent markings to fall off. Once fallen off, the originally clear directional information becomes incomplete, which may cause misunderstanding by road users such as drivers, pedestrians, or people inside buildings. This could lead to people getting lost in emergency situations due to a lack of proper guidance, increasing the risk of danger. Therefore, this invention proposes a road marking component that can be quickly replaced.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quickly replaceable road marking component, comprising a front support plate, a rear support plate, and a loading / unloading assembly. The front and rear support plates are movably connected via a pivot. The loading / unloading assembly is disposed on the outer surface of the front support plate. A fluorescent marker is fixedly connected to the side of the loading / unloading assembly away from the front support plate. The loading / unloading assembly includes an assembly groove. The surface of the front support plate has an assembly groove, and the inner wall of the assembly groove has a linkage groove. A telescopic rod is fixedly connected to the inner wall of the linkage groove. A push plate is fixedly connected to the telescopic end of the telescopic rod, and a return spring is fixedly connected to the side of the push plate near the telescopic rod. An assembly slot is fixedly connected to the inner wall of the assembly slot. A limit slot is opened on the side of the assembly slot away from the front support plate. An installation slot is opened inside the assembly slot. A limit spring is fixedly connected to the inner wall of the installation slot. A connecting plate is fixedly connected to the free end of the limit spring. A locking pin is fixedly connected to the side of the connecting plate away from the limit spring. A connecting column is fixedly connected to the side of the connecting plate near the limit spring. A square slot is opened on the side of the assembly slot near the fluorescent mark. A linkage frame is fixedly connected to the side of the connecting column near the square slot. An assembly block is provided on the inner wall of the assembly slot. A hanging ear is fixedly connected to the side surface of the assembly block. A locking groove is opened on the lower surface of the hanging ear.

[0007] Preferably, the push plate contacts the back of the mounting block, the push plate is rectangular, and the push plate contacts the inner wall of the front support plate. The push plate allows the user to unlock the mounting block and push it outward by the reset spring, thus facilitating the removal of the fluorescent label.

[0008] Preferably, there are three return springs, which are horizontally distributed at the center of the push plate. The return springs facilitate the application of a return force to the push plate.

[0009] Preferably, the connecting plate is in contact with the inner wall of the mounting column, the connecting plate is rectangular, and there are two connecting plates. The two connecting plates are symmetrically arranged at the center of the connecting column. The position of the locking pin is easily restricted by the cooperation of the connecting plate and the limiting spring.

[0010] Preferably, the locking pin is chamfered on the side near the linkage frame, the locking pin engages with the inner wall of the slot, and the locking pin is slidably connected to the inner wall of the mounting column. There are two locking pins, which are symmetrically arranged at the center of the mounting block. The locking pins help to restrict the position of the hanging ear to ensure the stability of the hanging ear in the locked state.

[0011] Preferably, the connecting post is rectangular in shape and contacts the inner wall of the mounting post. There are two mounting posts, which are symmetrically arranged at the center of the mounting block. The mounting posts facilitate the movement of the connecting plate to unlock the mounting block.

[0012] Preferably, the linkage frame is in contact with the inner wall of the square groove, and the position of the connecting column can be easily changed through the linkage frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this utility model, by setting up a loading and unloading component, when the fluorescent label needs to be replaced, the worker can hold the linkage frame with one hand and pull it down. The linkage frame cooperates with the square groove, driving the connecting column to move downward. As the connecting column moves downward, it also drives the rubber plate and the locking pin to move downward, which in turn compresses the limiting spring. The limiting spring deforms under the compression, causing the locking pin to move into the mounting groove until it is completely in the mounting groove. Then, the hanging ear is no longer restricted, and the mounting block loses pressure on the push plate. The reset spring then loses pressure, causing the telescopic rod to spring back and reset, pushing the push plate. The push plate then pushes the mounting block, which can be pushed out. The worker can then release the hand holding the linkage frame and remove the mounting block to replace the fluorescent label.

[0015] Once the replacement is complete, the mounting block can be realigned with the assembly slot and pushed into the slot until the lug contacts the chamfered edge of the locking pin. This engages with the locking pin, causing it to move downwards and press against the limiting spring. The limiting spring deforms under this pressure, and simultaneously, the mounting block contacts the push plate. As the mounting block moves, it pushes the push plate, causing the return spring to deform and move the telescopic rod and push plate towards the linkage slot until the mounting block reaches the locking slot. At this point, the limiting spring is no longer restricted and rebounds to reposition the lug. By incorporating this loading and unloading assembly, rapid replacement can be achieved, minimizing disruption to traffic and operations. When fluorescent signs need replacement, maintenance personnel can quickly remove the old sign and install the new one, significantly reducing maintenance time, thus minimizing traffic congestion and further improving maintenance efficiency.

[0025] Please see Figures 1-7 This utility model provides a technical solution: a road marking and sign component that can be quickly replaced, including a front support plate 1, a rear support plate 2 and a loading and unloading component 3. The front support plate 1 and the rear support plate 2 are movably connected by a pivot. The loading and unloading component 3 is set on the outer surface of the front support plate 1. A fluorescent sign 4 is fixedly connected to the side of the loading and unloading component 3 away from the front support plate 1.

[0026] In this embodiment: the loading and unloading assembly 3 includes an assembly groove 31. The surface of the front support plate 1 has an assembly groove 31. The inner wall of the assembly groove 31 has a linkage groove 32. A telescopic rod 33 is fixedly connected to the inner wall of the linkage groove 32. A push plate 34 is fixedly connected to the telescopic end of the telescopic rod 33. A return spring 35 is fixedly connected to the side of the push plate 34 near the telescopic rod 33. A mounting post 36 is fixedly connected to the inner wall of the assembly groove 31. A limit slot 37 is opened on the side of the mounting post 36 away from the front support plate 1. An installation groove 38 is opened inside the mounting post 36. A limit slot 38 is fixedly connected to the inner wall of the installation groove 38. A connecting plate 310 is fixedly connected to the free end of the spring 39 and the limiting spring 39. A locking pin 311 is fixedly connected to the side of the connecting plate 310 away from the limiting spring 39. A connecting post 312 is fixedly connected to the side of the connecting plate 310 close to the limiting spring 39. A square groove 313 is opened on the side of the mounting post 36 close to the fluorescent mark 4. A linkage frame 314 is fixedly connected to the side of the connecting post 312 close to the square groove 313. An mounting block 315 is provided on the inner wall of the assembly groove 31. A hanging ear 316 is fixedly connected to the side surface of the mounting block 315. A locking groove 317 is opened on the lower surface of the hanging ear 316.

[0027] Specifically, the push plate 34 contacts the back of the mounting block 315, the push plate 34 is rectangular, and the push plate 34 contacts the inner wall of the front support plate 1.

[0028] The effect achieved by the above components is as follows: by means of the push plate 34, the user can easily unlock the mounting block 315 and push the mounting block 315 outward by the reset spring 35, thereby making it convenient for the user to remove the fluorescent mark 4.

[0029] Specifically, there are three return springs 35, which are horizontally distributed at the center of the push plate 34.

[0030] The effect achieved by the above components is that the return spring 35 facilitates the application of a return force to the push plate 34.

[0031] Specifically, the connecting plate 310 contacts the inner wall of the mounting column 36. The connecting plate 310 is rectangular, and there are two connecting plates 310. The two connecting plates 310 are located at the center of the connecting column 312 and are arranged symmetrically from top to bottom.

[0032] The effect achieved by the above components is that the position of the locking pin 311 can be easily restricted through the cooperation between the connecting plate 310 and the limiting spring 39.

[0033] Specifically, the side of the locking pin 311 closest to the linkage frame 314 is chamfered. The locking pin 311 engages with the inner wall of the locking groove 317 and slides with the inner wall of the mounting column 36. There are two locking pins 311, which are symmetrically arranged at the center of the mounting block 315.

[0034] The effect achieved by the above components is that the position of the hook 316 can be restricted by the locking pin 311 to ensure the stability of the hook 316 in the locked state.

[0035] Specifically, the connecting post 312 is rectangular and contacts the inner wall of the mounting post 36. There are two mounting posts 36, which are symmetrically arranged at the center of the mounting block 315.

[0036] The effect achieved by the above components is that the position of the connecting plate 310 can be easily moved by the mounting post 36, so as to unlock the position of the mounting block 315.

[0037] Specifically, the linkage frame 314 is in contact with the inner wall of the square groove 313.

[0038] The effect achieved by the above components is that the position of the connecting column 312 can be easily changed through the linkage frame 314.

[0039] Working principle: When the fluorescent label 4 needs to be replaced, the operator can hold the linkage frame 314 with one hand and pull the linkage frame 314 downward. The linkage frame 314 cooperates with the square groove 313, which drives the connecting column 312 to move downward. As the connecting column 312 moves downward, it drives the rubber plate and the locking pin 311 to move downward at the same time, which moves and compresses the limiting spring 39. Then the limiting spring 39 deforms due to compression, causing the locking pin 311 to move into the mounting groove 38 until the locking pin 311 is completely moved into the mounting groove 38. Then the hanging ear 316 is no longer restricted, and the mounting block 315 loses pressure on the push plate 34. Then the return spring 35 loses pressure, which drives the telescopic rod 33 to spring back and reset, pushing the push plate 34. Then the push plate 34 pushes the mounting block 315, which can be pushed out. Then the operator can release the hand holding the linkage frame 314 and then remove the mounting block 315 to replace the fluorescent label 4.

[0040] Once the replacement is complete, the mounting block 315 can be realigned with the assembly slot 31 and pushed into the assembly slot 31 so that the lug 316 contacts the chamfer of the locking pin 311. This engages with the locking pin 311, causing it to press downwards. The locking pin 311 then moves downwards, pressing the limiting spring 39. The limiting spring 39 deforms under the pressure. Simultaneously, the mounting block 315 contacts the push plate 34. As the mounting block 315 moves, it pushes the push plate 34, causing the return spring 35 to deform under pressure, which in turn drives the telescopic rod 33 and the push plate. 34 moves towards the linkage slot 32 until the mounting block 315 moves to the slot 317, at which point the limit spring 39 is no longer restricted. The limit spring 39 rebounds and restricts the position of the hanging ear 316 again. By setting the loading and unloading assembly 3, it can be quickly replaced to reduce the impact on traffic and operation. When the fluorescent sign 4 needs to be replaced, maintenance personnel can quickly remove the old sign and install the new sign, which greatly shortens the maintenance time, thereby reducing the impact on traffic, reducing traffic congestion, and further improving maintenance efficiency.
