Implementation

[0024] The utility model is further described in conjunction with the following embodiments.

[0025] A specific implementation method of a car top guardrail fixed by a buckle of the utility model is as follows Figure 1 As shown, the car top guardrail includes a rear guardrail 1 and two side guardrails 2, the rear guardrail 1 is vertically arranged, and the two side guardrails 2 are vertically arranged on both end sides of the rear guardrail 1. The rear guardrail 1 is provided with a vertically arranged first column 11, and the side guardrail 2 is provided with a second column 21 abutting against the first column 11.

[0026] As an improvement, combined with Figures 2 to 3 The rear guardrail 1 and the side guardrail 2 are fixedly connected by a buckle assembly 3. Specifically, the buckle assembly 3 includes a fixing member 3 and a fixing plate 4, both ends of the fixing member 3 extend a first clamping portion 31 toward the fixing plate 4, both ends of the fixing plate 4 extend a second clamping portion 41 toward the fixing member 3, and each of the first clamping portion 31 and the second clamping portion 41 is provided with a mounting hole. In the assembled state, the fixing member 3 is installed on the side of the first column 11 and the second column 21, one of the first clamping parts 31 is close to and exceeds the side of the first column 11, and the other first clamping part 31 is close to and exceeds the side of the second column 21. The fixing plate 4 is inserted between the two first clamping parts 31, and the outer side of the second clamping part 41 is close to the inner side of the first clamping part 31. At this time, the mounting hole of the first clamping part 31 and the mounting hole of the second clamping part 41 are both in an aligned state, so that the fixing plate 4 and the fixing member 3 can be fastened by external bolts and nuts. After fastening, the fixing member 3 clamps and fixes the first column 11 and the second column 21, thereby realizing the fixed connection between the rear guardrail 1 and the side guardrail 2. The fixing plate 4 plays a role in positioning and shaping, which solves the problem that the fixing member 3 is large in deformation when it is suspended and fixed, and causes metal fatigue and loosening.

[0027] In order to prevent the fixing member 3 from sliding down to the bottom of the guardrail in the vertical direction, the fixing member 3 extends upwardly outwardly from a connecting portion 32, and the top end of the connecting portion 32 is bent outwardly to form a bent portion 33. In the assembled state, the bent portion 33 is closely attached to the top end surface of the second column 21. The bent portion 33 is used to prevent the fixing member 3 from sliding in the vertical direction and to limit the position of the rear guardrail 1, thereby preventing the rear guardrail 1 from moving in the vertical direction relative to the side guardrail 2.

[0028] As a preferred solution, see Figure 3The fixing member 3 is arranged in a U shape, and the fixing plate 4 is arranged in a U shape. The U-shaped structure is convenient for obtaining materials, and the fixing member 3 and the fixing plate 4 can be obtained by punching with channel steel.

[0029] The car top guardrail also needs to be installed with an inspection box and a footboard 6. In this embodiment, the side guardrail 2 also includes a crossbeam 22 arranged in the transverse direction and perpendicular to the second column 21. The car top guardrail of this embodiment also includes a hanging member, see Figure 4 The hanging member is arranged in a U shape, and a mounting portion 51 extends upward from the top of the hanging member. A through hole is provided in the mounting portion 51. In the assembled state, the hanging member is buckled on the crossbeam 22.

[0030] Please see Figure 5 The car top guardrail also includes a footboard 6. After the hanging member is buckled on the crossbeam 22, the mounting portion 51 of the hanging member is fixedly connected to the footboard 6 through bolts and nuts, so that the footboard 6 can be hung on the guardrail, which is convenient and quick to install. Figure 6 and Figure 7 The car top guardrail also includes a mounting bracket 7. Similarly, after the hanging member is buckled on the crossbeam 22 and the mounting bracket 7 is fixedly connected to the mounting portion 51 of the hanging member, the mounting bracket 7 can be hung on the guardrail. The mounting bracket 7 is used to fix the external maintenance box.

[0031] The present embodiment is a car roof guardrail that is fixed by snapping. In the assembled state, the fixing member 3 and the fixing plate 4 can be locked by means of external bolts and nuts in cooperation with the mounting holes of the fixing plate 4 and the mounting holes of the fixing member 3. The two first clamping parts 31 of the fixing member 3 can clamp the side guardrail 2 and the rear guardrail 1 to prevent loosening, thereby ensuring the connection strength between the two. No drilling and welding work is required, and the assembly is simple and convenient, which solves the problem of the troublesome assembly that required welding, drilling and assembly in the past. The overall structure is simple and compact, and the fixing member 3 and the fixing plate 4 can be standardized and mass-produced and then stored in the warehouse. Before construction, the materials can be picked according to the number of uses. The materials are easy to obtain, and the preparation is simple and convenient, which improves the assembly and production efficiency.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
