Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0020] like Figure 1-3 As shown, an embodiment of this utility model provides a guardrail, which includes: a frame 1 and a quick-connect mechanism 2. The quick-connect mechanism 2 includes a first connecting part 21 and a second connecting part 22. The first connecting part 21 includes an outer column 211 and a telescopic component 212. The outer column 211 is fixed to one side of the frame 1. The telescopic component 212 is disposed inside the outer column 211 and has a first state of being retracted into the outer column 211 and a second state of being partially protruding relative to the outer column 211. The second connecting part 22 is fixed to the other side of the frame 1 and has an opening 221. When the telescopic component 212 is in the first state, the outer column 211 can move in and out relative to the opening 221. When the telescopic component 212 is in the second state, the telescopic component 212 restricts the outer column 211 from being dislodged from the opening 221.

[0021] In use, multiple guardrails are arranged in a row, and the first connecting part 21 and the second connecting part 22 of adjacent guardrails are connected. The telescopic component 212 first switches to the first state, and then the outer column 211 enters the opening 221. The telescopic component 212 then switches to the second state, preventing the outer column 211 from detaching from the opening 221, thereby achieving the interconnection of adjacent guardrails. The entire connection process is simple and fast, effectively reducing the difficulty of operation and improving the connection efficiency of guardrails.

[0022] In this invention, the first connecting part 21 includes an outer column 211 and a telescopic component 212. The outer column 211 is fixed to one side of the frame 1, and the telescopic component 212 is disposed inside the outer column 211, having a first state of retracting into the outer column 211 and a second state of partially protruding relative to the outer column 211. The second connecting part 22 is fixed to the other side of the frame 1, and an opening 221 is provided on the second connecting part 22. In use, the telescopic component 212 first switches to the first state, and the outer column 211 then enters the opening 221. The telescopic component 212 then switches to the second state, restricting the outer column 211 from detaching from the opening 221, thereby achieving interconnection between adjacent guardrails. The entire connection process is simple and fast, effectively reducing operational difficulty and improving the connection efficiency of the guardrails, thus solving the problem of cumbersome guardrail assembly and disassembly processes in the prior art.

[0023] Specifically, the frame 1 is square, and a number of perforated holes 11 are provided on the frame 1. The function of the perforated holes 11 is to reduce the weight of the frame 1 and reduce the difficulty of moving the frame 1.

[0024] Furthermore, the surface of the frame 1 is provided with a warning label affixing area 12. In use, the user can affix some labels to the warning label affixing area 12.

[0025] Specifically, a connecting rod 213 extends from the top of the outer column 211, and the other end of the connecting rod 213 is fixed to the edge of the frame 1.

[0026] Specifically, the second connecting part 22 is cuboid in shape, and the opening 221 is opened on the side of the second connecting part 22 away from the frame 1 and passes through both ends of the second connecting part 22.

[0027] Furthermore, the opening 221 includes a first portion 221a and a second portion 221b. The inner diameter of the first portion 221a matches the outer diameter of the outer column 211. The second portion 221b communicates with the first portion 221a, and the inner diameter of the second portion 221b is larger than the outer diameter of the outer column 211. When the telescopic assembly 212 is in the first state, the outer column 211 can move along the first portion 221a into the second portion 221b. At this time, the telescopic assembly 212 is switched to the second state, and the telescopic assembly 212 restricts the outer column 211 to be within the second portion 221b, preventing the outer column 211 from moving along the first portion 221a and dislodging from the opening 221.

[0028] Specifically, the outer column 211 has several through holes 211a. When the telescopic component 212 is switched to the second state, part of the telescopic component 212 extends out through the through holes 211a.

[0029] Specifically, the telescopic assembly 212 includes a rotating screw 212a, a cone 212b, a telescopic column 212c, and a spring. A cavity is formed inside the outer column 211. The rotating screw 212a is threadedly connected to the outer column 211, with one end passing through the outer column 211 and extending into the cavity. The cone 212b is disposed in the cavity, and its bottom is fixed to the rotating screw 212a. The telescopic column 212c is disposed in the cavity, with one end located inside the through hole 211a and the other end abutting against the outer circumferential surface of the cone 212b. The spring is sleeved on the telescopic column 212c, with one end fixed to the telescopic column 212c and the other end fixed to the inner wall of the cavity.

[0030] In use, rotating the end of the rotating screw 212a outside the outer cylinder 211 causes the cone 212b to descend vertically. The cone 212b pushes the telescopic column 212c to extend relative to the through hole 211a, and the telescopic assembly 212 switches to the second state, thus limiting the outer cylinder 211. Conversely, rotating the end of the rotating screw 212a outside the outer cylinder 211 causes the cone 212b to rise vertically. The cone 212b returns to its original position under the push of the spring, and the telescopic column 212c retracts relative to the through hole 211a, and the telescopic assembly 212 switches to the first state.

[0031] The beneficial effects of this utility model are: The first connecting part of this utility model includes an outer column and a telescopic component. The outer column is fixed to one side of the frame, and the telescopic component is disposed inside the outer column, having a first state of retracting into the outer column and a second state of partially protruding relative to the outer column. The second connecting part is fixed to the other side of the frame, and an opening is provided on the second connecting part. In use, the telescopic component first switches to the first state, the outer column then enters the opening, and the telescopic component switches to the second state, preventing the outer column from detaching from the opening, thereby realizing the interconnection of adjacent guardrails. The entire connection process is simple and fast, effectively reducing the difficulty of operation and improving the connection efficiency of guardrails, thus solving the problem of cumbersome guardrail assembly and disassembly processes in the prior art.
