Description

Technical Field

[0001] This utility model belongs to the technical field of guardrail devices, and specifically relates to a guardrail that is easy to disassemble and install. Background Technology

[0002] Safety railings play an indispensable role in modern society. In the construction industry, from the construction phase of high-rise buildings to the daily use of residential buildings, safety railings are used at the edges of floors, stairwells, balconies, and other locations to prevent accidental falls. In the road traffic sector, highway guardrails and pedestrian barriers ensure the safety of vehicles and pedestrians, preventing traffic accidents. As people's safety awareness continues to improve, the safety and reliability of safety railings have become a key focus for various industries.

[0003] Chinese patent document CN221277433U, entitled "A Protective Fence," includes two guardrail frames, trapezoidal blocks, and rotating blocks. The two guardrail frames are connected by connecting rods and sliding rods. Rotating blocks are rotatably connected to both sides of each guardrail frame. Each rotating block can be fixed and rotated at a certain angle. A sliding groove is formed inside the rotating block, within which the trapezoidal block slides. In use, the rotating block is first rotated a certain angle, and then the trapezoidal block slides out to contact the ground, allowing the guardrail frame to stand stably on the ground. When the device needs to be folded up and moved, the worker simply slides the trapezoidal block into the groove and rotates the four rotating blocks into the guardrail frame. This reduces the space occupied by the guardrail and facilitates its movement.

[0004] Referring to the above technical solution, when multiple independent guardrails are placed on the ground in sequence, the guardrails are prone to tipping over when subjected to external impact, causing safety hazards. This utility model provides a guardrail that is easy to disassemble and install. The guardrails are tightly connected and have a stable structure, which can enhance the safety protection performance and is easy to install and disassemble, making it convenient for workers to transport the guardrails. Utility Model Content

[0005] The technical problem to be solved by this utility model is that when the guardrail is hit by an external force, it is easy to tip over due to the insufficient tightness of the connection between the guardrails, which causes a safety hazard.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a guardrail that is easy to disassemble and install, comprising a counterweight base and a guardrail body, wherein the counterweight base can fix the bottom of the guardrail, a rotating base is installed on the guardrail body, a connecting rod is installed on the rotating base, wherein the connecting rod can rotate under the drive of the rotating base, a locking block is slidably installed on the connecting rod, and a strong spring is connected between the locking block and the rotating base, wherein the strong spring, when pushed by an external force, can cause the locking block to slide back and forth on the connecting rod, a baffle is installed on the connecting rod, wherein the baffle can prevent the locking block from falling off, and the guardrail body has openings for two protective The first set of slots for horizontal connection of the main body of the guardrail includes a horizontal inlet slot, a rotating slot 1, and a vertical slot 1 that are adapted to the locking block. That is, the locking block can enter through the horizontal inlet slot and rotate in the rotating slot 1, and finally lock into the first set of slots. A connecting slot is opened on the first vertical slot. A second vertical slot and a second rotating slot are provided on one side of the connecting slot, which are adapted to the baffle. That is, when the baffle passes through the connecting slot, the strong spring is gradually compressed, and the baffle can be locked into the second vertical slot. At this time, the locking block can be tightly locked into the first vertical slot, realizing the horizontal connection between the two guardrail main bodies, which can make the structure of the connected guardrail main bodies more stable.

[0007] Optionally, the rotating base has a locking hole, and a fixed base is installed on the main body of the guardrail. A locking post is slidably installed on the fixed base, and a compression spring is connected between the locking post and the fixed base. Under the action of the compression spring, the locking post can be tightly attached to the rotating base. After the rotating base has rotated, the locking post can be locked into the locking hole to fix the rotating base.

[0008] Optionally, a rubber pad is provided around the locking post, which can enhance the tightness of the connection between the locking post and the locking hole.

[0009] Optionally, the rotating base consists of an inner shell and an outer shell. The inner shell is fixedly installed on the main body of the guardrail and has an annular groove. The outer shell has an annular block, which is engaged in the annular groove. That is, the outer shell can rotate around its own axis under the limitation of the annular groove and the annular block.

[0010] Optionally, an arc-shaped plate is installed on the outer shell, and a fan-shaped right-angle groove is opened on the inner shell for limiting the rotation of the arc-shaped plate. Under the limitation of the fan-shaped right-angle groove, the arc-shaped plate can make the outer shell rotate back and forth by 90 degrees. While meeting the usage requirements, it can prevent the outer shell from driving the connecting rod to rotate excessively, and enhance the connection stability between the connecting rod and the main body of the guardrail.

[0011] Optionally, an auxiliary plate is installed on the main body of the guardrail. The auxiliary plate has a second set of slots for connecting two guardrail bodies in a vertical position. The second set of slots has the same design structure as the first set of slots. That is, the second set of slots allows the two guardrail bodies to be installed at a right angle, improving the practicality of the device and allowing for flexible installation and use of the guardrail bodies.

[0012] Optionally, a cross-shaped support plate can be installed on the main body of the guardrail. That is, the cross-shaped support plate can enhance the structural stability of the main body of the guardrail.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Firstly, by having the rotating base, connecting rod, locking block, strong spring, and baffle respectively cooperate with the locking slot group one or locking slot group two, two or more guardrails can be connected together. When the guardrail is subjected to external impact, the tightness of the connection between the main body of the guardrail can enhance the overall stability of the guardrail and enhance its safety protection performance.

[0015] Secondly, when installing the two guardrails, simply align the connecting rod, locking block, and baffle with the horizontal inlet slot and push them into the connecting slot. Then, rotate the base clockwise by 90 degrees. Under the elastic force of the strong spring, the locking block will be tightly engaged in the first vertical locking slot, and the baffle will be tightly engaged in the second vertical locking slot. When disassembling, gradually move the baffle out of the connecting slot. The elastic force of the strong spring will be gradually released, thus enabling the disassembly of the two guardrails. The installation and disassembly are simple, making it convenient for workers to transport the guardrails.

[0016] Thirdly, by setting up slot group one, slot group two, rotating base, connecting rod, locking block and strong spring, two guardrails can be connected horizontally or vertically to meet the needs of different usage scenarios and enhance the flexibility and practicality of guardrail use.

[0030] Reference Figure 1 and Figure 2 A cross-shaped support plate 11 is installed on the main body 1 of the guardrail. The cross-shaped support plate 11 is installed on the rear side wall of the main body 1 of the guardrail, which can enhance the structural strength of the main body 1 of the guardrail and improve the safety of the device during use.

[0031] When using this device, the operator first brings two adjacent guardrail bodies 1 close together, aligning the locking assembly 2 with the slot group 3. The locking block 23 then gradually enters the rotating slot 32 along the horizontal inlet 31. At this time, the baffle 25 is located inside the connecting slot 34. A force is applied again to bring the two guardrail bodies 1 closer together, causing the baffle 25 to pass through the connecting slot 34 and reach the rotating slot 36. The strong spring 24 is compressed. Then, the rotating base 21 is rotated 90 degrees clockwise. Simultaneously, the locking block 23 gradually rotates within the rotating slot 32 until it engages with the vertical slot 33, and the baffle 25 gradually rotates within the rotating slot 36 until it engages with the vertical slot 35, thus achieving a horizontal connection between the two guardrail bodies 1. When it is necessary to connect the two guardrail bodies 1 vertically, simply align the locking assembly 2 with the slot group 51 and repeat the above operation.

[0032] Then, pull the locking post 43 outward so that one end of the locking post 43 is locked in the locking hole 41, thereby limiting and fixing the rotating base 21, preventing the rotating base 21 from rotating, and ensuring the tightness of the guardrail connection.

[0033] During disassembly, pull the locking pin 43 outward so that one end of the locking pin 43 moves out of the locking hole 41, releasing the limiting fixation on the rotating base 21. Then, push the baffle 25 slightly into the rotating groove 2 36 so that the baffle 25 disengages from the vertical locking groove 2 35. Rotate the rotating base 21 counterclockwise by 90 degrees. Simultaneously, the locking block 23 gradually rotates from the rotating groove 1 32 to the rotating groove 2 36, and the baffle 25 gradually rotates from the vertical locking groove 2 35 to the position of the corresponding connecting groove 34. The strong spring 24 gradually returns to its original state, applying a pushing force to the locking block 23 and the baffle 25, so that the locking block 23 moves out of the vertical locking groove 1 33 and the baffle 25 moves out of the connecting groove 34, thus realizing the disassembly between the two guardrail bodies 1.
