Description

Technical Field

[0001] This utility model belongs to the field of security roadblock technology, and in particular relates to a foldable anti-collision barricade. Background Technology

[0002] In areas such as traffic control, military defense, and security of important locations, barricades are frequently used to prevent vehicles from illegally entering. While traditional barricades can be effective, they have drawbacks, such as large size, inconvenient transportation, and difficulty in storage. Furthermore, traditional barricades typically rely on swivel casters for anchoring to the ground, resulting in poor stability; they serve only a warning purpose and are unlikely to effectively stop vehicles from impacting.

[0003] Therefore, there is an urgent need for a type of roadblock that has both good anti-collision performance and is easy to fold, store, and transport. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a foldable anti-collision barricade that solves the problems of existing barricades being large in size, difficult to store and transport, and difficult to effectively block collisions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a foldable anti-collision barricade, including a second frame hinged to a first frame, a fixing device provided on the side of the first frame facing the ground, and a positioning base that can be fixed to the ground is detachably connected to the fixing device.

[0006] The first frame is hinged to a first joint tube at the end opposite to the second frame, and the second frame is hinged to a second joint tube at the end opposite to the first frame. A locking plate that can be hinged to the second joint tube is rotatably connected to the first joint tube. The locking plate and the second joint tube or the first joint tube are provided with a pin hole for inserting a positioning pin.

[0007] When the first joint tube, the second joint tube, and the locking plate are collinear, the pin hole on the locking plate can correspond to the pin hole on the first joint tube or the second joint tube.

[0008] Optionally, the fastener includes a sleeve disposed on the first frame, and a locking post capable of vertical extension and rotation is movably embedded in the sleeve, and a locking pin is disposed on the outer periphery of the locking post.

[0009] The positioning base includes a positioning base tube with one end sealed, and a base tube cover plate is provided at the other end of the positioning base tube. The base tube cover plate is provided with a slot through hole, and the locking pin and the locking post can be embedded into the interior of the positioning base tube through the slot through hole.

[0010] Optionally, the first frame and the second frame, the first frame and the first joint tube, and the second frame and the second frame are respectively hinged by a set of joint plates.

[0011] Optionally, the sleeve has a groove, and the outer periphery of the locking post is connected to a locking handle that can extend from the groove to the outside of the sleeve. When the locking handle slides along the groove, the locking post can move up and down and rotate relative to the sleeve.

[0012] Optionally, a spring is provided inside the sleeve and sleeved around the outer periphery of the locking post. The spring is elastically supported between the sleeve and the locking post, and the spring can drive the locking post to retract inside the sleeve.

[0013] Optionally, a bayonet post is rotatably connected to the second frame, and one end of the bayonet post is provided with a bayonet handle that can rotate synchronously with the bayonet post.

[0014] Optionally, a caster wheel is provided on the side of the first frame facing the ground.

[0015] Optionally, the first frame and the second frame are coated with a protective coating for visibility.

[0016] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: By simultaneously inserting positioning pins into the locking plate and the pin holes on the first or second joint tube, the positions of the first frame, the second frame, and the first and second joint tubes can be locked, forming a stable triangular structure for blocking vehicles. When the positioning pins are removed, the first and second joint tubes, the first and first frame, the second and second frame, and the first and second frame can rotate freely within a certain angle range, allowing for folding to reduce the space occupied by the entire barricade, facilitating transportation and storage. Furthermore, in this technical solution, the barricade can also be fixed to the ground through the connection between the fixing device and the positioning base, effectively increasing the barricade's impact resistance.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] like Figures 1-5As shown, a foldable anti-collision barricade includes a second frame 2 hinged to a first frame 1. A fixing device 3 is provided on the side of the first frame 1 facing the ground, and the fixing device 3 is detachably connected to a positioning base 4 that can be fixed to the ground. A first joint tube 101 is hinged to the end of the first frame 1 away from the second frame 2, and a second joint tube 201 is hinged to the end of the second frame 2 away from the first frame 1. A locking plate 5 that can be hinged to the second joint tube 201 is rotatably connected to the first joint tube 101. The locking plate 5 and the second joint tube 201 or the first joint tube 101 are provided with a pin hole 6 for inserting a positioning pin. When the first joint tube 101, the second joint tube 201 and the locking plate 5 are collinear, the pin hole 6 on the locking plate 5 can correspond to the pin hole 6 on the first joint tube 101 or the second joint tube 201.

[0027] Specifically, when the first joint tube 101, the second joint tube 201, and the locking plate 5 are aligned on the same straight line, the pin hole 6 on the locking plate 5 corresponds to the pin hole 6 on the first joint tube 101 or the second joint tube 201. At this time, the first frame 1, the second frame 2, the first joint tube 101, and the second joint tube 201 can form a triangular structure. Then, the positioning pin is inserted into the corresponding pin hole 6 on the locking plate 5 and the first joint tube 101 or the second joint tube 201 to lock the relative position of the first joint tube 101 and the second joint tube 201. At this time, a stable barricade structure can be formed. At the same time, the fixing device 3 provided on the first frame 1 can be connected to the positioning base 4 fixed on the ground. This structure fixes the barricade structure to the ground, thereby effectively increasing the anti-collision capability of the barricade.

[0028] The barricade in this technical solution can be fixed to the ground using the fixing device 3 and the positioning base 4 when needed. Simultaneously, after the positioning pin is removed, the first joint tube 101 and the second joint tube 201, the first joint tube 101 and the first frame 1, the second joint tube 201 and the second frame 2, and the first frame 1 and the second frame 2 can rotate freely within a certain angle range. This allows for folding to reduce the space occupied by the entire barricade, facilitating transportation by vehicles, boats, and other means of transport. It also makes it easy to store in warehouses, garages, and other locations, greatly improving space utilization and reducing transportation and storage costs.

[0029] As described above, the first frame 1 and the second frame 2, the first frame 1 and the first joint tube 101, and the second frame 2 and the second frame 2 are respectively hinged by a set of joint plates 7. The joint plates 7 can effectively increase the degree of freedom of the hinge between the first frame 1 and the first joint tube 101 and between the second frame 2 and the second frame 2, and can make the folding angle between each structure smaller, so that the folded volume of the barricade in this technical solution is smaller and more convenient for transportation and storage.

[0030] The above, such as Figures 3-5 As shown, the fixing device 3 includes a sleeve 301 mounted on the first frame 1. A locking post 302, capable of vertical extension and rotation, is movably embedded within the sleeve 301. A locking pin 303 is provided on the outer periphery of the locking post 302. The positioning base 4 includes a positioning bottom tube 401 sealed at one end, with a bottom tube cover plate 402 at the other end. The bottom tube cover plate 402 has a slot through hole 4021, through which the locking post 302 and locking pin 303 can be embedded into the positioning bottom tube 401. Specifically, the positioning base 4 can be pre-embedded in the ground, forming a fixed anchor point. Simultaneously, the positioning base 4 can be quickly fixed to the ground using fasteners such as expansion bolts, drilling bolts, and self-tapping screws, allowing the barricade in this technical solution to be used in locations outside the designated areas. Furthermore, the locking post 302 can extend from the sleeve 301, but cannot extend completely from the sleeve 301. The locking pin 302 and locking pin 303 can be inserted into the positioning base tube 401 through the slot through hole 4021 on the base tube cover plate 402. Then, by rotating the locking pin 302, the position of the locking pin 303 is misaligned with the position of the slot through hole 4021. At this time, the locking pin 302 cannot be pulled out from the positioning base tube 401, and the barricade is locked in place on the ground. At the same time, when it is necessary to release the barricade from its locked position on the ground, simply rotate the locking pin 302 again so that the locking pin 303 on the locking pin 302 aligns with the position of the slot through hole 4021, and the locking pin 302 can be pulled out from the positioning base tube 401.

[0031] Furthermore, to facilitate the extension, retraction, and rotation of the locking pin 302, such as... Figure 3 As shown, the sleeve 301 has a groove 3011, and the outer periphery of the locking post 302 is connected to a locking handle 3021 that can extend from the groove 3011 to the outside of the sleeve 301. When the locking handle 3021 slides along the groove 3011, the locking post 302 can move up and down and rotate relative to the sleeve 301.

[0032] Meanwhile, to facilitate the removal of the locking pin 302 from the positioning base tube 401, such as Figure 4As shown, a spring 304 is sleeved around the outer periphery of the locking pin 302 inside the sleeve 301. The spring 304 elastically supports the sleeve 301 and the locking pin 302, and can drive the locking pin 302 to retract into the sleeve 301. That is, after the locking pin 302 is extended out of the sleeve 301 by the locking handle 3021, the spring 304 is compressed, thereby accumulating kinetic energy. After the locking pin 302 is rotated by the locking handle 3021 so that the position of the locking pin 303 corresponds to the position of the slot through hole 4021, the spring 304 can release the accumulated kinetic energy and drive the locking pin 302 to retract into the sleeve 301. Meanwhile, when the locking pin 302 is embedded in the positioning tube 401 and the locking pin 303 is misaligned with the slot through hole 4021, the kinetic energy stored in the spring 304 can drive the locking pin 303 to abut against the tube cover plate 402, thereby preventing the locking pin 302 from being accidentally pulled out of the positioning tube 401 and improving the safety of the roadblock.

[0033] In this embodiment, a bayonet post 8 is rotatably connected to the second frame 2, and a bayonet handle 9 is provided at one end of the bayonet post 8, which can rotate synchronously with the bayonet post 8. The bayonet post 8 is a square or round tube with a row of bayonets. By rotating the bayonet handle 9, the side of the bayonet post 8 with bayonets can face the oncoming vehicle, so as to enhance the impact resistance and destructive power of the barricade in special circumstances. Furthermore, the second frame 2 can be provided with positioning holes that correspond to different positions of the bayonet handle 9, and positioning pins that can be inserted into the positioning holes can be inserted into the bayonet handle 9 to limit the position of the bayonet post 8.

[0034] Furthermore, such as Figure 1 , Figure 2 As shown, a caster wheel 10 is provided on the side of the first frame 1 facing the ground. When the locking post 302 is retracted into the sleeve 301, the caster wheel 10 can sit on the ground to facilitate the relocation of the barricade.

[0035] In this technical solution, the first frame 1 and the second frame 2 are coated with a protective coating for visibility. The protective coating is one or more of the existing anti-rust paint, fluorescent paint, and reflective paint, so that the barricade has a good visibility effect both day and night.

[0036] Working principle: By folding the first frame 1 and the second frame 2, the first joint tube 101, the second joint tube 201, and the locking plate 5 can be aligned in a straight line. At this time, the pin hole 6 on the locking plate 5 can correspond to the pin hole 6 on the first joint tube 101 or the second joint tube 201. Then, the positioning pin is inserted into the corresponding pin hole 6 on the locking plate 5 and the first joint tube 101 or the second joint tube 201 to lock the relative position of the first joint tube 101 and the second joint tube 201. At this time, the first frame 1, the second frame 2, and the first joint tube 101 and the second joint tube 201 can form a stable triangular structure, which can be used to prevent vehicles from illegally entering. At the same time, the positioning base 4 can be pre-embedded or fixed in the ground to form a fixed anchor point on the ground. The first frame 1, the second frame 2, the first joint tube 101, the second joint tube 201, and other structures are moved on the ground by the casters 10. When the fixing device 3 on the first frame 1 is moved above the positioning base 4, the locking pin 302 can be extended from the sleeve 301 by operating the locking handle 3021. The locking pin 302 and the locking pin 303 can be embedded into the positioning base tube 401 through the slot through hole 4021 on the base tube cover plate 402. Then, the locking pin 302 is rotated so that the position of the locking pin 303 is misaligned with the position of the slot through hole 4021. At this time, the locking pin 302 cannot be pulled out from the positioning base tube 401, and the barricade can be locked on the ground to increase the anti-collision performance of the barricade.

[0037] Meanwhile, after the positioning pin is removed, the first joint tube 101 and the second joint tube 201, the first joint tube 101 and the first frame 1, the second joint tube 201 and the second frame 2, and the first frame 1 and the second frame 2 can rotate freely within a certain angle range, so as to reduce the space occupied by the entire barricade by folding, making it convenient for transportation and storage.

[0038] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
