Description

Technical Field

[0001] This utility model relates to the field of public security control technology, and in particular to a temporary public security control isolation fence. Background Technology

[0002] Temporary security control barriers are used during large-scale events or emergencies to guide traffic, ensure smooth roads, and maintain public order.

[0003] In the prior art, such as Chinese Patent No. CN221502926U, a temporary security control and maintenance fence is disclosed, including a first fence and multiple second fences placed on both sides thereon. The interiors of the first fence and the multiple second fences are all hollow. Multiple connecting members are evenly arranged inside the first fence and the multiple second fences, and a hinge plate is hinged together among the multiple connecting members. A driving component for extending and retracting the hinge plate is provided inside the first fence. A support component is provided on one side of the first fence and the multiple second fences. A banner connecting shell is provided on one side of the second fence. The banner connecting shell has a fixing component for installing a banner inside. The driving component facilitates adjustment of the position between the first fence and the multiple second fences, making the fence suitable for use in different locations. It also facilitates the retraction and storage of the fence, improving the convenience of transportation and storage.

[0004] In the above technical solution, storage is achieved by rotating the hinge plate by rotating the bidirectional screw. However, the knob and the bidirectional screw do not have a limit mechanism. During storage and carrying, the knob and the bidirectional screw may be accidentally rotated, causing the hinge plate to rotate and open the guardrail, affecting the storage and carrying effect. Furthermore, the bottom of the guardrail is in direct contact with the ground. During storage, due to the high friction between the ground and the guardrail, the guardrail needs to be lifted before storage, which is time-consuming and laborious.

[0005] Based on this, a temporary security control barrier is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a temporary security control barrier to solve the problems mentioned in the background art.

[0007] The technical solution of this utility model is: a temporary security control isolation fence, including a guardrail 1 and multiple guardrail 2. The inner wall of the guardrail 1 is slidably connected to two connecting blocks 1, and the inner wall of the guardrail 2 is slidably connected to two connecting blocks 2. The opposing surfaces of the two connecting blocks 1 and the two connecting blocks 2 are rotatably connected to a hinge rod. The top of the guardrail 1 is fixedly connected to a mounting box. The inner wall of the mounting box is rotatably connected to a rotating shaft. The surface of the rotating shaft is fixedly connected to a pawl. The inner wall of the guardrail 1 is rotatably connected to a bidirectional screw rod. The top of the bidirectional screw rod extends into the inner cavity of the mounting box. The surface of the bidirectional screw rod is fixedly connected to a ratchet. The top of the bidirectional screw rod is fixedly connected to a knob. The surface of the pawl is provided with a disengagement device.

[0008] In some embodiments, the disengagement device includes a spring fixedly connected to the surface of the pawl, one end of the spring being fixedly connected to the inner wall of the mounting box, a fixing rod fixedly connected to the upper surface of the pawl, a lever rotatably connected to the surface of the fixing rod, and one end of the lever penetrating the surface of the mounting box.

[0009] In some embodiments, a U-shaped plate is fixedly connected to one side of the guardrail, a pull rod is slidably connected to one side of the U-shaped plate, a pressure plate is fixedly connected to one end of the pull rod, and a tension spring is sleeved on the surface of the pull rod.

[0010] In some embodiments, threaded holes are provided through the upper surfaces of both connecting blocks, and the inner walls of the two threaded holes are respectively screwed to the surface of the bidirectional lead screw.

[0011] In some embodiments, a sliding rod is fixedly connected to the inner wall of the second guardrail, and sliding holes are provided on the upper surfaces of the two second connecting blocks. The inner walls of the two sliding holes are slidably connected to the surfaces of the sliding rods, and rollers are fixedly installed at the bottom ends of the two second guardrails.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, when storing the guardrail, the lever is pulled, which causes the pawl to rotate on the surface of the shaft, thus separating the pawl from the ratchet. Then, the knob is reversed to make the two connecting blocks move towards each other on the inner wall of the guardrail, thus storing the guardrail. After storage, the lever is released, and the lever causes the ratchet to limit the ratchet again.

[0014] Secondly, this utility model allows the two connecting blocks to move in opposite directions on the inner wall of the guardrail by rotating the knob, thereby opening the hinge rod and unfolding the guardrail. The rollers at the bottom of the left and right guardrails can reduce friction with the ground, allowing the guardrail to be unfolded and stored simply by placing it on the ground.

[0015] This solves the problem that the knob and two-way lead screw are easily turned due to accidental touch, causing the hinge plate to rotate and open the guardrail, thus affecting the storage and carrying effect. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved temporary security control barrier. The technical solution of this utility model is as follows:

[0025] like Figures 1-4As shown, a temporary security control barrier includes a first barrier 1 and multiple second barriers 4. Four second barriers 4 are equidistantly distributed on both sides of the first barrier 1. Two connecting blocks 1 2 are slidably connected to the inner wall of the first barrier 1, and two connecting blocks 2 10 are slidably connected to the inner wall of the second barriers 4. A hinge rod 3 is rotatably connected to the opposite surfaces of the two connecting blocks 1 2 and the two connecting blocks 2 10. The hinge rod 3 can connect two adjacent barriers between the connecting blocks 1 2 and the connecting blocks 2 10. A mounting box 7 is fixedly connected to the top of the first barrier 1. A rotating shaft 16 is rotatably connected to the inner wall of the mounting box 7. A pawl 17 is fixedly connected to the surface of the rotating shaft 16. A bidirectional screw 6 is rotatably connected to the inner wall of the first barrier 1. The top of the bidirectional screw 6 extends into the inner cavity of the mounting box 7. A ratchet 15 is fixedly connected to the surface of the bidirectional screw 6. A knob 8 is fixedly connected to the top of the bidirectional screw 6. The bottom of the knob 8 is rotatably set between the bottom of the knob 8 and the upper surface of the mounting box 7. A release device is provided on the surface of the pawl 17.

[0026] like Figure 3 and Figure 4 As shown, in one embodiment, the disengagement device includes a spring 18 fixedly connected to the surface of the pawl 17. One end of the spring 18 is fixedly connected to the inner wall of the mounting box 7. A fixing rod 19 is fixedly connected to the upper surface of the pawl 17. A lever 20 is rotatably connected to the surface of the fixing rod 19. A waist hole is provided through the upper surface of the lever 20, which can facilitate pulling when the lever 20 is pulled. One end of the lever 20 penetrates the surface of the mounting box 7.

[0027] A U-shaped plate 11 is fixedly connected to one side of guardrail 2 4. A pull rod 12 is slidably connected to one side of the U-shaped plate 11. A pressure plate 13 is fixedly connected to one end of the pull rod 12. A tension spring 14 is sleeved on the surface of the pull rod 12. The pressure plate 13 is made of rubber, which can increase friction and improve the pressure effect.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, threaded holes are provided through the upper surfaces of both connecting blocks 2, and the inner walls of the two threaded holes are respectively screwed to the surface of the bidirectional lead screw 6.

[0029] The inner wall of guardrail 2 4 is fixedly connected with a sliding rod 9. The upper surface of the two connecting blocks 2 10 is provided with sliding holes. The inner walls of the two sliding holes are slidably connected to the surface of the sliding rod 9. The bottom ends of the two guardrails 2 4 are fixedly installed with rollers 5. The rollers 5 can reduce friction when the guardrail is placed on the ground during unfolding and storage, and can be rolled solidly, saving time and effort. At the same time, it is convenient to move the guardrail. The rollers 5 are rollers with a braking effect in the prior art. When the guardrail is unfolded and used, the rollers 5 can be locked to improve stability.

[0030] The specific working method is as follows: When using the guardrail, rotating the knob 8 drives the bidirectional screw 6 to rotate, which allows the two connecting blocks 2 to move in opposite directions on the inner wall of the guardrail 1, thereby opening the hinge rod 3 and realizing the unfolding of the guardrail. The rollers 5 at the bottom of the left and right guardrails 4 reduce friction with the ground, allowing the guardrail to be placed on the ground for unfolding and storage. During unfolding, the bidirectional screw 6 drives the ratchet 15 on its surface to self-lock with the pawl 17, realizing the rotation... The limit switch on knob 8 prevents it from reversing and affecting the stability of the guardrail when unfolded. When folding, first pull lever 20. Lever 20 causes pawl 17 to rotate on the surface of shaft 16, separating pawl 17 from ratchet 15. This allows knob 8 to be reversed, causing the two connecting blocks 2 to move towards each other on the inner wall of guardrail 1, thus folding the guardrail. After folding, release lever 20. Lever 20 then causes the ratchet to reposition itself, limiting ratchet 15 again. This prevents the knob 8 and the two-way lead screw 6 from easily colliding.

[0031] Accidental activation caused the hinge plate to rotate and open the guardrail, affecting the storage and carrying efficiency.

[0032] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
