Description

Technical Field

[0001] The utility model relates to the technical field of urban traffic, and more particularly to an anti-collision column for road traffic. Background Art

[0002] With the development of society, cities are becoming more and more prosperous, and the corresponding problems are becoming more and more complicated. With the increase of urban population and the affluence of people's lives, there are more and more private cars, and the traffic pressure in cities is also increasing. There are a considerable number of road traffic accidents every year, which have a great impact on the personal and property safety of citizens. Anti-collision columns can be used to isolate vehicles, limit and guide the movement of vehicles, and help manage traffic.

[0003] In general, the function of a crash column is to warn vehicles and prevent them from passing, rather than to block them and prevent them from passing. Therefore, the structure is simple and the impact resistance is insufficient. However, in a complex traffic environment, the driver may make a mistake in driving or lose control of the vehicle, causing the vehicle to hit the crash column. At this time, the crash column with limited impact resistance is subjected to a large impact, causing damage to the equipment. Moreover, after the crash column is damaged by excessive impact, it can no longer be used and needs to be replaced with a new crash column. In order to have stronger stability, the crash columns in some locations will be pre-buried and then fixed to the ground with other fixing processes, so that the crash column and the ground form an integral whole. The disassembly of this type of crash column is too troublesome and inconvenient to replace. In addition, when a collision occurs, if the driver is drunk or in other uncontrollable states, the vehicle will hit the crash column at a high speed and will not be able to stop in time. At this time, the impact caused by the collision will not only damage the crash column, but also cause harm to the driver due to the reaction force. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a road traffic anti-collision column with the following features:

[0018] Beneficial effects:

[0019] 1. A buffer structure is formed by the coordination of the column tube, the inner support tube and the buffer spring. When receiving an impact, the buffer spring absorbs the impact. The elastic column and the inner support tube cooperate to provide a structure for absorbing impact force. By coordinating multiple groups of structures for absorbing impact force, the impact force is reduced multiple times, providing an effective anti-collision structure, and reducing damage to the equipment when the vehicle collides with the anti-collision column, as well as damage to the vehicle itself.

[0020] 2. The base provides a supporting structure, the insertion block cooperates with the column tube to provide a disassembly and assembly structure, and the insertion frame, the fixing bolt and the fixing groove cooperate to provide a fixing structure. The fixing structure is easy to operate, so that the column tube is fixed on the fixing seat, which is convenient for replacement after the column tube is damaged and convenient for workers to operate.

[0021] 3. Through the cooperation of the connecting plate and the rigid easy-tear connecting strip, a breakable connection fixing structure is provided, which breaks when subjected to a certain tensile force. Thus, when subjected to a large impact, the device breaks and separates from the base. After absorbing a certain impact force, it no longer blocks the vehicle, allowing the vehicle to pass, avoiding a large impact feedback that may injure the driver. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned direction words are not used to limit the present invention.

[0031] See also Figure 1-5 A road traffic anti-collision column includes a base 1, a column tube 2 is provided on the base 1, an inner support tube 3 is provided in the column tube 2, a buffer spring 4 is provided between the column tube 2 and the inner body tube, the column tube 2 and the inner support tube 3 are both made of relatively soft materials, an elastic column 5 is provided in the inner support tube 3, and the elastic column 5 cooperates with the base 1;

[0032] An insertion block 6 is provided at the lower end of the column tube 2, and an insertion frame 7 is provided on the base 1. The insertion block 6 cooperates with the insertion frame 7. A fixing bolt 8 is provided on the insertion frame 7. The fixing bolt 8 is threadedly engaged with the insertion frame 7. A fixing groove 9 is opened at the outer end of the insertion block 6, and the fixing groove 9 cooperates with the fixing bolt 8.

[0033] In this embodiment, the base 1 provides an installation structure, supporting column tube 2 and other equipment. When the vehicle collides with the column tube 2, if the impact force is not large, the column tube 2 will transfer the impact to the buffer spring 4 after the impact, and the impact force is absorbed by the buffer spring 4. The cooperation between the inner support tube 3 and the elastic column 5 makes the elastic column 5 have a high strength and will not be directly and completely absorbed, providing a supporting effect, thereby reducing the impact generated during the collision, which is convenient for protecting the anti-collision column on the one hand and protecting the driver on the other hand. If the impact force increases, it cannot be absorbed by the buffer spring 4 alone, and the side impact will be transmitted to the elastic column 5, causing the elastic column 5 to bend, thereby absorbing a large amount of impact force, and dissolving the impact force that the buffer spring 4 cannot absorb, thereby protecting the anti-collision column and the driver. After the vehicle stops, the elastic column 5 will be reset by its own elasticity.

[0034] More specifically, when disassembling the column structure, by controlling the cooperation between the fixing bolt 8 and the insertion frame 7, the fixing bolt 8 slides horizontally along the insertion frame 7, so that the front end of the fixing bolt 8 leaves the fixing groove 9 or is inserted into the fixing groove 9, thereby realizing the release or fixation of the insertion block 6, and the column structure including the insertion block 6 can be freely disassembled.

[0035] See also Figure 4As an implementation method for separating the equipment: a connecting plate 10 is provided at the lower end of the column tube 2, and a rigid tearable connecting strip 11 is provided at the lower end of the connecting plate 10. The other end of the rigid tearable connecting strip 11 cooperates with the insertion block 6. When subjected to a large impact, the column structure will be separated from the base 1, allowing the vehicle to pass by, avoiding a large impact that hurts the driver.

[0036] Specifically, under the connection of the connecting plate 10, the column tube 2 is matched with the insertion block 6 through the rigid tearable connecting strip 11. When the column tube 2 is subjected to excessive impact, the equipment cannot stop the vehicle. Under the strong impact, the rigid tearable connecting strip 11 breaks, thereby separating the connecting plate 10 from the insertion block 6, and separating the column structure such as the column tube 2, the inner support tube 3 and the elastic column 5 from the base 1, so that the vehicle passes and avoids causing greater harm to the driver.

[0037] See also Figure 4 As a further implementation of the connecting disk: a connecting hole 12 is opened at the lower end of the insertion block 6, a connecting head 13 is provided at one end of the rigid tearable connecting strip 11, and a rotating cap 14 is provided at the other end. A connecting groove 15 is opened at the lower end of the connecting disk 10, the connecting groove 15 cooperates with the connecting head 13, and the rotating cap 14 cooperates with the connecting hole 12, so that the overall result is smooth.

[0038] Specifically, when installing the rigid tearable connecting strip 11, insert it from the connecting hole 12, pass the connecting head 13 through the connecting hole 12 and cooperate with the connecting groove 15, and control it by rotating the cap 14, so that the connecting plate 10 is connected to the insertion block 6 through the rigid tearable connecting strip 11.

[0039] See also Figure 1 As a further implementation of the column tube: a buffer pad 16 is provided at the outer end of the column tube 2, and a buffer block 17 is provided on the buffer pad 16. There are multiple buffer blocks 17 and they are evenly distributed on the buffer pad 16 to further improve the buffering effect.

[0040] Specifically, when the column tube 2 receives an impact, the buffer pad 16 provides a buffering effect, and a large number of buffer blocks 17 cooperate to first contact the impacting object, thereby further improving the buffering effect.

[0041] See also Figure 5 As a further implementation of the column tube: a mounting groove 18 is provided on the buffer pad 16, and a reflective strip 19 is provided in the mounting groove 18 to provide a warning effect.

[0042] Specifically, the mounting groove 18 provides space for installing the reflective strip 19. At night, the light of a moving vehicle shines on the reflective strip 19, which reflects the light and reminds the driver that there is an obstacle ahead.

[0043] See also Figure 1-Figure 3As a further implementation of the base: a grounding hole 20 is opened at the outer end of the base 1, and a grounding cone 21 is provided in the grounding hole 20 to facilitate the fixation of the base 1.

[0044] Specifically, when fixing the base 1 , the grounding cone 21 is inserted through the grounding hole 20 and into the ground surface, thereby fixing the base 1 .

[0045] See also Figure 1 As a further implementation of the grounding cone: the outer end of the grounding cone 21 is provided with a reinforced thread 22, and the upper end of the grounding cone 21 is provided with a driving handle 23, which is convenient for controlling the fixation of the base 1.

[0046] Specifically, when installing the grounding cone 21, the grounding cone 21 is controlled to rotate by the driving handle 23, so that the grounding cone 21 cooperates with the soil layer on the ground through the reinforced thread 22 on the surface. Under the action of the reinforced thread 22, the grounding cone 21 is more stably embedded in the soil, and the thread structure will form a blocking structure to prevent the grounding cone 21 from being directly pulled out, making the base 1 more stable.

[0047] See also Figure 1-Figure 3 As a further embodiment of the insertion frame: a sinking groove 24 is provided on the insertion frame 7, a bolt cap 25 is provided on the outer end of the fixing bolt 8, and a tool groove 26 is provided on the bolt cap 25.

[0048] Specifically, when operating the fixing bolt 8, a tool is inserted into the tool groove 26 to fix the tool and the bolt cap 25 together, and the fixing bolt 8 is controlled so that the bolt cap 25 enters the groove 24, thereby preventing the fixing bolt 8 from being loosened due to external impact. In addition, the tool groove 26 can be uniquely configured so that general tools cannot be replaced, thereby reducing the risk of opening by others.

[0049] To sum up, when the overall device is in use or running:

[0050] When using the device, first fix the base 1, insert the grounding cone 21 through the grounding hole 20, and control the rotation of the grounding cone 21 by the driving handle 23, so that the grounding cone 21 cooperates with the ground layer through the reinforced thread 22 on the surface. Under the action of the reinforced thread 22, the grounding cone 21 is more stably embedded in the soil, and the thread structure will form a blocking structure to prevent the grounding cone 21 from being directly pulled out, making the base 1 more stable, thereby fixing the base 1. Then, when installing each column structure, install the rigid tearable connecting strip 11 and insert it from the connecting hole 12, so that the connecting head 13 passes through the connecting hole 12 and cooperates with the connecting groove 15, and is controlled by the rotating cap 14, so that the connecting plate 10 is connected to the insertion block 6 through the rigid tearable connecting strip 11. Then the insertion block 6 is installed into the insertion frame 7 so that the fixing groove 9 is aligned with the fixing bolt 8. By controlling the cooperation between the fixing bolt 8 and the insertion frame 7, the fixing bolt 8 slides laterally along the insertion frame 7 so that the front end of the fixing bolt 8 is inserted into the fixing groove 9, thereby fixing the insertion block 6. When operating the fixing bolt 8, a tool is inserted into the tool groove 26 to fix the tool and the bolt cap 25 together. The fixing bolt 8 is controlled so that the bolt cap 25 enters the groove 24 to prevent the fixing bolt 8 from loosening due to external impact. The tool groove 26 can be uniquely set so that general tools cannot be replaced, thereby reducing the need for others to open it. The above steps can be reversed to remove the insertion block 6. When necessary, the equipment can be disassembled, and each column structure can be placed or replaced.

[0051] The base 1 provides an installation structure to support the column tube 2 and other equipment. When the column tube 2 is hit by a vehicle, if the impact force is not large, then after the column tube 2 is hit, when the column tube 2 receives the impact, a buffering effect is provided by the buffer pad 16. A large number of buffer blocks 17 cooperate to contact the impact object first, further improving the buffering effect. The extra impact will be transmitted to the buffer spring 4, and the impact force is absorbed by the buffer spring 4. The cooperation between the inner support tube 3 and the elastic column 5 has a higher strength and will not be directly and completely absorbed, providing a supporting effect, thereby reducing the impact generated during the collision. On the one hand, it protects the anti-collision column, and on the other hand, it protects the driver. If the impact force increases, it cannot be absorbed by the buffer spring 4 alone, and the side impact will be transmitted to the elastic column 5, causing the elastic column 5 to bend, thereby absorbing a large amount of impact. The impact force of the impact will dissipate the impact force that the buffer spring 4 cannot absorb, and protect the anti-collision column and the driver. After the vehicle stops, the elastic column 5 will reset through its own elasticity. Under the connection of the connecting plate 10, the column tube 2 will cooperate with the insertion block 6 through the rigid tear-away connecting strip 11. When the column tube 2 is subjected to excessive impact, the equipment cannot stop the vehicle. Under the strong impact, the rigid tear-away connecting strip 11 will break, thereby separating the connecting plate 10 from the insertion block 6, and thus separating the column structure such as the column tube 2, the inner support tube 3 and the elastic column 5 from the base 1, so that the vehicle passes and avoids causing greater harm to the driver. In addition, at night, the lights of the moving vehicle will shine on the reflective strip 19, which will reflect the light to remind the driver that there is an obstacle ahead.

[0052] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
