Description

Technical Field

[0001] This utility model relates to the technical field of roadblock interception equipment, specifically a quick-assembly barricade protection device. Background Technology

[0002] A chevaux-de-frise is a mobile barrier, primarily used by the defensive side as an auxiliary facility when constructing a defensive position. It is named after its ancient use in defending against cavalry. In modern times, chevaux-de-frise are often used to block roads or important areas, such as the entrances to government compounds, to allow guards to stand watch before and after the chevaux-de-frise, strictly controlling the entry and exit of vehicles and personnel, and effectively ensuring traffic order and the safety of major facilities and locations.

[0003] The existing barricades are a single, welded structure, meaning they cannot be disassembled once assembled. Due to their fixed structure, they are quite bulky and difficult to transport, taking up a large amount of vehicle space during transport, limiting the number that can be transported and resulting in high transportation costs. Utility Model Content

[0004] The purpose of this invention is to provide a quick-assembly anti-barrier device that is easy to fold, reduce its size, and facilitate transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly anti-barrier device, comprising a bottom support frame, a front support frame sleeved on the bottom support frame, and a bracket slidably mounted on the bottom support frame. The bottom support frame includes a front crossbar, a rear crossbar, and two side support rods, with both ends of the side support rods vertically fixed to the front and rear crossbars respectively. The front support frame includes an upper crossbar and a lower crossbar, with the lower crossbar sleeved on the front crossbar and rotatably connected to the rear crossbar. The bracket includes a sliding ring, a concave block, a support connecting rod, and a connecting groove. The sliding ring is slidably mounted on the surface of the side support rods, the concave block is mounted on the sliding ring, and both ends of the support connecting rod are rotatably connected to the concave block and the connecting groove respectively. Both ends of the front and rear crossbars are equipped with a moving wheel mechanism.

[0006] Specifically, the movable wheel mechanism includes a rotating ring and universal wheels mounted on the rotating ring. The rotating ring is fitted over both ends of the front crossbar and the rear crossbar and can rotate freely on the front crossbar and the rear crossbar.

[0007] Specifically, two mutually symmetrical limiting rings are installed on the surface of the rotating ring, and a fixing hole adapted to the limiting ring is opened on the surface of the side support rod, and a limiting post is installed on the fixing hole.

[0008] Specifically, the sliding ring has a limiting hole, a limiting post is installed on the limiting hole, and the side support rod has multiple fixing holes that are adapted to the limiting hole on its surface.

[0009] Specifically, an auxiliary rod is installed between the upper and lower crossbars, and multiple round nails are installed on the auxiliary rod.

[0010] Compared with existing technologies, this quick-assembly anti-barrier device has the following advantages:

[0011] This quick-assembly anti-barrier device allows for easy transport by detaching the upper crossbar from the connecting slot, folding the support rod onto the side support rod, and rotating and folding the front support frame onto the bottom support frame. This reduces the overall size of the device, minimizes the space required for transport, and facilitates transportation. Additionally, by rotating the caster mechanism, one end of the caster wheel can be placed on the ground, making it easy to move the device. Attached Figure Description

In addition, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0020] like Figure 1-4 As shown, this utility model embodiment provides a quick-assembly anti-barrier device. The quick-assembly anti-barrier device includes a bottom support frame 1, a front support frame 2 sleeved on the bottom support frame 1, and a bracket 3 slidably mounted on the bottom support frame 1. The bottom support frame 1 includes a front crossbar 11, a rear crossbar 12, and two side support rods 13. The two ends of the side support rods 13 are vertically fixed to the front crossbar 11 and the rear crossbar 12, respectively. The front support frame 2 includes an upper crossbar 21 and a lower crossbar 22. The lower crossbar 22 is sleeved on the front crossbar 11 and rotatably connected to the rear crossbar 12. The bracket 3 includes a sliding ring 31, a concave block 32, a supporting connecting rod 33, and a connecting groove 34. The sliding ring 31 is slidably mounted on the surface of the side support rods 13, the concave block 32 is mounted on the sliding ring 31, and the two ends of the supporting connecting rod 33 are rotatably connected to the concave block 32 and the connecting groove 34, respectively.

[0021] The front support frame 2 can rotate around the front crossbar 11 via the lower crossbar 22, and the sliding ring 31 can move on the surface of the side support rod 13. Under normal use, the support connecting rod 33 on the rotating bracket 3 installs the connecting groove 34 at both ends of the upper crossbar 21 to fix the front support frame 2 and meet the normal use requirements. When not in use, the upper crossbar 21 is disengaged from the connecting groove 34 by rotating the front support frame 2, and then the support connecting rod 33 is folded and placed on the side support rod 13. The front support frame 2 is rotated and folded and placed on the bottom support frame 1, which reduces the volume of the entire device, reduces the space occupied during transportation, has the advantage of being easy to transport, and thus reduces transportation costs.

[0022] Furthermore, the sliding ring 31 has a limiting hole 9, and a limiting post 10 is installed on the limiting hole 9. The side support rod 13 has multiple fixing holes 41 that are adapted to the limiting hole 9. Through the limiting post 10 and the fixing holes 41, the position of the sliding ring 31 on the side support rod 13 can be controlled, thereby adjusting the height of the front support frame 2 so that the device can be used in places with different heights.

[0023] Both ends of the front crossbar 11 and the rear crossbar 12 are equipped with a moving wheel mechanism. The moving wheel mechanism includes a rotating ring 4 and a universal wheel 5 installed on the rotating ring 4. The rotating ring 4 is sleeved on both ends of the front crossbar 11 and the rear crossbar 12 and can rotate freely on the front crossbar 11 and the rear crossbar 12. When the device needs to be moved, the moving wheel mechanism rotates one end of the universal wheel 5 downward to the ground, which facilitates the movement of the device. Conversely, when the device does not need to be moved, turning one end of the universal wheel 5 upward can increase the stability of the entire device.

[0024] Furthermore, two symmetrical limiting rings 6 are installed on the surface of the rotating ring 4. The side support rod 13 has a fixing hole 7 that matches the limiting ring 6. The sliding ring 31 also has a fixing hole 7, which does not hinder the movement of the sliding ring 31. A limiting post 8 is installed on the fixing hole 7. The limiting post 8 passes through the limiting ring 6 and is installed on the fixing hole 7, which can limit the rotating ring 4 and prevent the rotating ring 4 from moving freely. This can prevent the rotating ring 4 from rotating when moving with the caster 5, making it easier for the user to use.

[0025] Furthermore, an auxiliary rod 23 is installed between the upper crossbar 21 and the lower crossbar 22. Multiple round nails 24 are installed on the auxiliary rod 23. The multiple round nails 24 serve as a warning and can also be used to hang various warning signs to remind people.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
