[0018] The specific embodiments of the utility model will be described in detail below with reference to the drawings, but the description of the embodiments by the applicant is not a limitation on the technical solutions, and any changes in form but not in substance according to the concept of the utility model should be regarded as the protection scope of the utility model.
[0019] In the following description, the directional or positional concepts of up, down, left, right, front and back are all based on the positions shown in the corresponding drawings, so they should not be understood as special limitations on the technical solutions provided by the utility model.
[0020] Please refer to Figure 1 and Figure 2 The utility model relates to a telescopic roof guardrail, including corner connecting piece 1, rear guardrail 2, side guardrail 3, rear guardrail 2 both ends are fixedly connected with corner connecting piece 1, side guardrail 3 has two and is installed on the corner connecting piece 1 of rear guardrail 2 both ends.
[0021] The corner connecting piece 1 includes a vertical connecting pipe 12 and multiple horizontal connecting pipes 11, two horizontal connecting pipes 11 arranged vertically at right angles are arranged on the vertical connecting pipe 12 at different heights. In the embodiment, two horizontal connecting pipes 11 arranged vertically are arranged at the upper, middle and lower positions of the vertical connecting pipe 12, and the horizontal connecting pipe 11 is welded to the vertical connecting pipe 12.
[0022] The rear guardrail 2 and the side guardrail 3 both include multiple horizontal guardrail rods 21 and multiple vertical guardrail rods 22, and multiple vertical guardrail rods 22 arranged at intervals are connected between every two horizontal guardrail rods 21, so that the horizontal guardrail rods 21 and the vertical guardrail rods 22 are connected to each other to form a flat frame guardrail structure. The length and thickness of the horizontal guardrail rods 21 on the rear guardrail 2 and the horizontal guardrail rods 21 on the side guardrail 3 can be the same or different, and since they are all horizontally installed and have the same functions, they are collectively referred to as horizontal guardrail rods 21.
[0023] The horizontal guardrail rods 21 on the rear guardrail 2 and the side guardrail 3 and the horizontal connecting pipes 11 on the corner connecting piece 1 are inserted into each other and then locked by nuts through fasteners 4 passing through the overlapping horizontal guardrail rods 21 and horizontal connecting pipes 11 to realize installation. The specific structure is described by the following embodiments: Embodiment 1
[0024] As Figure 1As shown, the transverse guardrails 21 on the rear guardrail 2 and the side guardrail 3 correspond to the transverse connecting pipes 11 on the corner connecting piece 1, the transverse guardrails 21 are hollow pipes for the transverse connecting pipes 11 to be inserted, and the hollow pipes are square pipes or round pipes. A plurality of mounting through holes 5 corresponding to each other are arranged on the transverse guardrails 21 and the transverse connecting pipes 11, and in the embodiment, the plurality of mounting through holes 5 are arranged side by side. After the transverse connecting pipe 11 is inserted into the pipe of the transverse guardrail 21 and the relative positions of the two are adjusted, the fastener 4 is passed through the mounting through holes 5 corresponding to each other on the transverse guardrail 21 and the transverse connecting pipe 11 and is locked by a nut, so as to realize the fixed installation of the transverse guardrail 21 and the transverse connecting pipe 11. In the embodiment, the rear guardrail 2 and the side guardrail 3 each include three layers of transverse guardrails 21, which correspond to the transverse connecting pipes 11 at three positions on the corner connecting piece 1. Embodiment 2
[0025] The difference between the embodiment 2 and the embodiment 1 is that when the end of the rear guardrail 2 and / or the side guardrail 3 close to the corner connecting piece 1 is not provided with the vertical guardrail 22, the transverse guardrail 21 can be designed to be inserted into the transverse connecting pipe 11, at this time, the transverse connecting pipe 11 is a hollow pipe for the transverse guardrail 21 to be inserted, and the hollow pipe is a square pipe or a round pipe. A plurality of mounting through holes 5 corresponding to each other are arranged on the transverse guardrails 21 and the transverse connecting pipes 11, and in the embodiment, the plurality of mounting through holes 5 are arranged side by side. After the transverse connecting pipe 11 is inserted into the pipe of the transverse guardrail 21 and the relative positions of the two are adjusted, the fastener 4 is passed through the mounting through holes 5 corresponding to each other on the transverse guardrail 21 and the transverse connecting pipe 11 and is locked by a nut, so as to realize the fixed installation of the transverse guardrail 21 and the transverse connecting pipe 11.
[0026] In summary, the three main components of the technical solution are relatively simple and easy to manufacture, can be transported to the site separately, and are easy to install on site. The depth and width of the guardrail can be adjusted according to the actual size of the roof, and the adjustment and fixation are very simple.
