Description

Technical Field

[0001] This utility model relates to the field of isolation and warning technology, specifically to an isolation and warning device for municipal roads. Background Technology

[0002] During road construction or other operations, the stable installation of multiple rows of road safety barriers in appropriate locations to effectively separate roads is a crucial safety measure. Its purpose is to prevent pedestrians or vehicles from accidentally entering the construction area, thereby avoiding accidents.

[0003] However, most of the isolation posts currently on the market are too large. Furthermore, in practical applications, they require connecting straps or frames to connect to each other, which undoubtedly adds complexity to the usage process and also brings many inconveniences to transportation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a municipal road isolation warning device, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A municipal road isolation warning device includes a support plate and a first fixing frame, wherein a second fixing frame is installed on the top surface of the support plate;

[0007] Support blocks are installed at both ends of the support plate;

[0008] Warning brackets are mounted on both ends of the first fixed frame via rotating shafts. A rotating shaft is welded onto the rotating shaft, and a through hole is opened inside the rotating shaft. Both ends of the first fixed frame are provided with a first L-shaped limiting frame and a second L-shaped limiting frame. A first fixing pin is installed on the inner wall of the first L-shaped limiting frame via a first compression spring, and a second fixing pin is installed on the inner wall of the second L-shaped limiting frame via a second compression spring. The second fixing pin and the first fixing pin respectively enter the through hole to limit the connecting block.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, a first screw is threadedly installed inside the support block, and an anti-slip pad is fixed to the bottom end of the first screw.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] By incorporating an adjustable first screw within the support block, the screw's extension length can be adjusted according to different road conditions, ensuring a closer contact between the device and the ground. The presence of anti-slip pads significantly increases the friction between the device and the ground, effectively preventing displacement or tipping of the entire isolation and warning device during use, thus significantly improving its stability and ensuring reliable isolation and warning performance even in complex environments.

[0013] Furthermore, reflective strips are attached to the warning frame.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] Reflective strips have excellent reflective properties. In low-visibility environments such as dim lighting or nighttime, when vehicle headlights or other light sources shine on the reflective strips, they reflect the light back, attracting the attention of road users. This effectively improves the visibility of the warning strips, allowing pedestrians and vehicles to clearly perceive the presence of the warning device even from a distance, enabling them to react in advance, avoid accidentally entering the construction area, reduce the risk of accidents, and provide stronger protection for road traffic safety.

[0016] Furthermore, both the first L-shaped limiting frame and the second L-shaped limiting frame are fixed with mounting blocks, and the mounting blocks are installed on the first fixed frame by bolts.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The design of the mounting block and bolts makes the installation and removal of the first and second L-shaped limit frames very convenient. When the device needs maintenance, replacement of parts, or adjustment, workers can quickly remove the limit frames from the first fixed frame, improving the efficiency of maintenance work.

[0019] Furthermore, a second screw is fixedly installed on the bottom end face of the first fixing frame, and the second screw is installed in the second fixing frame by means of threads.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The threaded connection between the second screw and the second fixing bracket provides a reliable and adjustable way to connect the first fixing bracket and the second fixing bracket, allowing the first fixing bracket and the second fixing bracket to be disassembled and assembled, thereby reducing the space occupied and facilitating assembly for use.

[0022] Furthermore, a first gripping frame is installed on the first fixing pin, the first gripping frame is slidably sleeved in the first L-shaped limiting frame, and the first gripping frame is sleeved in the first compression spring.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The first grip is designed to provide the operator with a convenient point for applying force. When the position of the warning frame needs to be adjusted, the operator can easily overcome the elastic force of the first compression spring by gripping the first grip, and pull the first fixing pin out of the through hole of the rotating shaft, thereby enabling the warning frame to rotate around the rotating shaft.

[0025] Furthermore, a second gripping bracket is installed on the second fixing pin, the second gripping bracket is slidably sleeved in the second L-shaped limiting bracket, and the second gripping bracket is sleeved in the second compression spring.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] Similar to the first grip, the second grip facilitates the operation of the second fixing pin. In practical use, when it is sometimes necessary to adjust the rotation of the warning frame to open or close, the second grip allows the operator to easily insert or remove the second fixing pin to adjust the rotation of the warning frame.

[0028] This utility model provides a municipal road isolation and warning device. It has the following beneficial effects:

[0029] An adjustable first screw is installed inside the support block, which can adjust the length according to different road conditions, so that the device can fit more closely to the ground. Combined with anti-slip pads, the friction between the device and the ground is greatly increased, effectively preventing the device from shifting or tipping over during use, and ensuring that it can reliably play its role in isolation and warning in complex environments.

[0030] The reflective strips installed on the warning frame have excellent reflective properties. In low-visibility environments such as dim light or nighttime, they can reflect vehicle lights or other light sources back, attracting the attention of road users, improving the visibility of the warning frame, allowing pedestrians and vehicles to react in advance, avoiding accidental entry into the construction area, and reducing the risk of accidents.

[0031] The first and second L-shaped limit brackets are mounted on the first fixed bracket via mounting blocks and bolts. This design makes the installation and disassembly of the limit brackets very convenient, improving the efficiency of maintenance work when the device needs repair, replacement of parts, or adjustment. Furthermore, the first and second fixed brackets are connected by a second screw and thread, providing a reliable and adjustable connection between them, facilitating disassembly and assembly, and reducing space occupation and ease of use.

[0032] The first and second fixing pins are respectively equipped with a first grip and a second grip, providing operators with convenient points for applying force. When it is necessary to adjust the position of the warning frame, the operator can easily overcome the elastic force of the compression spring by holding the grip and pull the fixing pin out of the through hole of the rotating shaft, thereby realizing the rotation of the warning frame around the rotating shaft, facilitating the adjustment operations such as rotating, unfolding or closing the warning frame.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1 to 4As shown, the embodiments provided by this utility model are as follows:

[0043] Example 1

[0044] A municipal road isolation warning device includes a support plate 1 and a first fixing frame 104, and a second fixing frame 106 is installed on the top surface of the support plate 1.

[0045] Support blocks 101 are installed at both ends of the support plate 1;

[0046] Warning brackets 2 are mounted on both ends of the first fixed frame 104 via rotating shafts 202. A rotating shaft 202 is welded onto the rotating shaft 202, and a through hole 204 is opened inside the rotating shaft 202. A first L-shaped limiting frame 3 and a second L-shaped limiting frame 4 are provided on both ends of the first fixed frame 104. A first fixing pin 302 is installed on the inner wall of the first L-shaped limiting frame 3 via a first compression spring 303. A second fixing pin 402 is installed on the inner wall of the second L-shaped limiting frame 4 via a second compression spring 403. The second fixing pin 402 and the first fixing pin 302 respectively enter the through hole 204 to limit the connecting block 203.

[0047] A first screw 102 is threadedly installed inside the support block 101, and an anti-slip pad 103 is fixedly attached to the bottom end of the first screw 102. By setting an adjustable first screw 102 inside the support block 101, the length of the screw extension can be adjusted according to different road conditions, making the contact between the device and the ground more intimate. The presence of the anti-slip pad 103 greatly increases the friction between the device and the ground, effectively preventing the entire isolation warning device from shifting or tipping over during use, significantly improving the stability of the device, and ensuring that it can reliably perform its isolation warning function in complex environments.

[0048] A second screw 105 is fixedly installed on the bottom end face of the first fixing bracket 104, and the second screw 105 is threadedly installed in the second fixing bracket 106. The threaded connection between the second screw 105 and the second fixing bracket 106 provides a reliable and adjustable way for the connection between the first fixing bracket 104 and the second fixing bracket 106, so that the first fixing bracket 104 and the second fixing bracket 106 can be disassembled and assembled to reduce the space occupied and facilitate assembly for use.

[0049] Example 2

[0050] To reduce space occupation during the deployment and closure of municipal road isolation warning systems, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0051] A reflective strip 201 is attached to the warning frame 2. The reflective strip 201 has excellent reflective properties; in low-visibility environments such as dim lighting or nighttime, when vehicle headlights or other light sources shine on the reflective strip 201, it reflects the light back, attracting the attention of road users. This effectively improves the visibility of the warning frame 2, allowing pedestrians and vehicles to clearly perceive the presence of the warning device even from a distance, enabling them to react in advance, avoid accidentally entering the construction area, reduce the risk of accidents, and provide stronger protection for road traffic safety.

[0052] Mounting blocks 401 are fixed to both the first L-shaped limiting frame 3 and the second L-shaped limiting frame 4, and the mounting blocks 401 are bolted to the first fixed frame 104. The design of the mounting blocks 401 and the bolts makes the installation and removal of the first L-shaped limiting frame 3 and the second L-shaped limiting frame 4 very convenient. When the device needs maintenance, replacement of parts, or adjustment, the staff can quickly remove the limiting frame from the first fixed frame 104, improving the efficiency of maintenance work.

[0053] A first gripping bracket 301 is mounted on the first fixing pin 302. The first gripping bracket 301 is slidably sleeved within the first L-shaped limiting bracket 3 and is also sleeved within the first compression spring 303. The first gripping bracket 301 provides an easy point for the operator to apply force. When the position of the warning bracket 2 needs to be adjusted, the operator can easily overcome the elastic force of the first compression spring 303 by gripping the first gripping bracket 301, and pull the first fixing pin 302 out of the through hole 204 of the rotating shaft 202, thereby realizing the rotation of the warning bracket 2 around the rotating shaft 202.

[0054] A second gripping bracket 404 is mounted on the second fixing pin 402. The second gripping bracket 404 is slidably sleeved within the second L-shaped limiting bracket 4 and is also sleeved within the second compression spring 403. Similar to the first gripping bracket 301, the second gripping bracket 404 facilitates the operation of the second fixing pin 402. In practical use, when it is sometimes necessary to adjust the rotation of the warning frame 2 to open or close, the second gripping bracket 404 allows the operator to easily insert and remove the second fixing pin 402 to adjust the rotation of the warning frame 2.

[0055] Working principle:

[0056] Adjustable first screws 102 are installed inside the support blocks 101 at both ends of the support plate 1. By rotating the first screws 102, the length of the screws extending out of the support blocks 101 can be changed to adapt to different road conditions and make the device fit the ground more closely. Anti-slip pads 103 are fixed to the bottom end face of the first screws 102, increasing the friction between the device and the ground, preventing the device from shifting or tipping over during use, and achieving stable installation of the device.

[0057] The warning frame 2 is mounted on both ends of the first fixed frame 104 via a pivot 202. The connecting block 203 on the pivot 202 has multiple spaced through holes 204. A first L-shaped limiting frame 3 and a second L-shaped limiting frame 4 are respectively installed at both ends of the first fixed frame 104. The first L-shaped limiting frame 3 is fitted with a first fixing pin 302 via a first compression spring 303, and the second L-shaped limiting frame 4 is fitted with a second fixing pin 402 via a second compression spring 403. In the initial fixed state, the first fixing pin 302 is inserted into the corresponding through hole 204 on the connecting block 203, firmly fixing the warning frame 2 in its current position. At this time, the second fixing pin 402 is not in contact with the connecting block 203. When it is necessary to adjust the angle of the warning frame 2, the operator holds the first grip 301, overcoming the elastic force of the first compression spring 303, and pulls the first fixing pin 302 out of its current through hole 204. At this time, the warning frame 2 loses the limitation of the first fixing pin 302 and can rotate freely via the pivot 202. During the rotation of the warning frame 2 to a suitable angle, when the through hole 204 on the connecting block 203 moves to the position opposite to the second fixing pin 402, the second fixing pin 402 will be inserted into the through hole 204 under the elastic force of the second compression spring 403, thus limiting and fixing the rotated warning frame 2. If it is necessary to close the frame to reduce space usage later, grasp the second grip 404, pull out the second fixing pin 402, and repeat the above operation to rotate the warning frame 2 to a new position. Then, the first fixing pin 302 will be inserted into the corresponding through hole 204 for limiting, thus achieving the adjustment and fixing of the warning frame 2 in a cyclical manner.

[0058] A reflective strip 201 is attached to the warning frame 2. In low-visibility environments such as dim light or night, when vehicle headlights or other light sources shine on the reflective strip 201, the reflective strip 201 can reflect the light back, attracting the attention of road users and improving the visibility of the warning frame 2. This allows pedestrians and vehicles to notice the presence of the isolation warning device in advance and avoid accidentally entering the construction area.

[0059] Mounting blocks 401 are fixed to the first L-shaped limit frame 3 and the second L-shaped limit frame 4, and are bolted to the first fixed frame 104. This design facilitates the quick removal of the limit frame from the first fixed frame 104 when the device needs maintenance, replacement of parts or adjustment, thus improving maintenance efficiency.

[0060] A second screw 105 is fixedly installed on the bottom end face of the first fixing frame 104, and the second screw 105 is threaded into the second fixing frame 106. This threaded connection provides a reliable and adjustable connection between the first fixing frame 104 and the second fixing frame 106, which can realize the disassembly and assembly of the two, reduce the space occupied when not in use, facilitate assembly when in use, and thus realize convenient transportation and movement when closed and disassembled.
