[0017] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model. On the contrary, the embodiments of the present utility model include all variations, modifications and equivalents falling within the spirit and scope of the appended claims.

[0018] The guardrail post fixing device according to an embodiment of the present utility model will be described below in conjunction with the accompanying drawings.

[0019] As Figure 1 and Figure 2 shown, the guardrail post fixing device according to an embodiment of the present utility model may include a support base 10, a support assembly 20 and a drive assembly 30.

[0020] Among them, the support assembly 20 may include a support cylinder 21 and a plurality of fixing mechanisms 22. Among them, the support cylinder 21 is vertically and fixedly arranged on the support base 10, and the support cylinder 21 is used for installing the guardrail post. It should be noted that the inner diameter of the support cylinder 21 described in this embodiment is slightly larger than the outer diameter of the guardrail post.

[0021] In this embodiment, a plurality of mounting holes 11 are formed in the support base 10 around the support cylinder 21. It can be understood that the support base 10 can be fixed by a threaded fastener such as a bolt or a screw passing through the mounting holes 11.

[0022] A plurality of fixing mechanisms 22 are longitudinally arranged side by side and movably arranged inside the side wall of the support cylinder 21. For example, the plurality of fixing mechanisms 22 may be 2, 3, 4, 5, 6 fixing mechanisms 22, etc. The specific number of settings can be selected according to actual situations and will not be limited here. The drive assembly 30 may include an installation box 31, a transmission mechanism 32 and a drive mechanism 33.

[0023] Among them, the installation box 31 covers the plurality of fixing mechanisms 22, that is, the installation box 31 covers the plurality of fixing mechanisms 22 inside the installation box 31, and the installation box 31 is fixedly connected to the support base 10.

[0024] The transmission mechanism 32 is arranged in the installation box 31 in a lifting and moving manner, and the transmission mechanism 32 is respectively in contact connection with the plurality of fixing mechanisms 22.

[0025] The drive mechanism 33 is rotatably arranged on the installation box 31, and the drive mechanism 33 is in contact connection with the transmission mechanism 32.

[0026] To clearly illustrate the above embodiment, in an embodiment of the present utility model, as Figure 2 shown, the fixing mechanism 22 may include a baffle 221, a guide rod 222 and a spring 223.

[0027] Among them, a chute 201 is formed in the side wall of the support cylinder 21, and the baffle 221 is movably arranged in the chute 201.

[0028] The guide rod 222 is fixedly arranged on the baffle 221, and one end of the guide rod 222 penetrates into the support cylinder 21, and the other end of the guide rod 222 penetrates into the mounting box 31. It should be noted that the other end of the guide rod 222 described in this embodiment is a semi-spherical dome.

[0029] The spring 223 is sleeved on the guide rod 222, and one end of the spring 223 is fixedly connected to the baffle 221, and the other end of the spring 223 is fixedly connected to the end wall of the chute 201.

[0030] Furthermore, in an embodiment of the present invention, as Figure 2 shown, the transmission mechanism 32 may include a transmission rod 321 and a tension spring 322.

[0031] Among them, the transmission rod 321 is arranged to move up and down in the mounting box 31, and a plurality of right-angled trapezoidal grooves 301 are formed on the transmission rod 321. Among them, the inclined surface of the right-angled trapezoidal groove 301 abuts against the other end of the guide rod 222. It should be noted that the number of the plurality of right-angled trapezoidal grooves 301 described in this embodiment is the same as the number of the plurality of fixing mechanisms 22.

[0032] The tension spring 322 is fixedly arranged in the mounting box 31, and the tension spring 322 is fixedly connected to the bottom end of the transmission rod 321.

[0033] Furthermore, in an embodiment of the present invention, as Figure 2 shown, the driving mechanism 33 may include a bolt 331 and a conical driving rod 332. Among them, the bolt 331 is threadedly connected to the mounting box 31, the conical driving rod 332 is fixedly arranged on the bolt 331, and the conical surface of the conical driving rod 332 abuts against the top end of the transmission rod 321.

[0034] Specifically, when it is necessary to fix the guardrail column, the relevant staff first needs to fix the support base 10. After the support base 10 is fixed, the staff can insert the bottom end of the guardrail column into the support cylinder 21.

[0035] Then, the staff can drive the bolt 331 by a screwdriver to drive the conical driving rod 332 to rotate. During the rotation of the bolt 331, the conical driving rod 332 is simultaneously driven to move towards the transmission rod 321. The moving conical driving rod 332 exerts a downward pressure on the transmission rod 321. At this time, the transmission rod 321 is pressed to move downward and compress the tension spring 322.

[0036] The downward moving transmission rod 321 applies pressure to the guide rod 222 through the inclined surface of the right trapezoidal groove 301. The guide rod 222 is pressed and moves towards the guardrail post. The moving guide rod 222 presses the bottom of the guardrail post tightly within the support cylinder 21, thereby fixing the guardrail post within the support cylinder 21. During the movement of the transmission rod 321, the baffle 221 is simultaneously driven to compress the spring 223.

[0037] When it is necessary to disassemble the guardrail post for maintenance, the staff can drive the bolt 331 to rotate in the reverse direction, thereby driving the conical drive rod 332 to move away from the transmission rod 321 and releasing the pressure applied to the transmission rod 321. At this time, the transmission rod 321 is reset under the tension of the tension spring 322. At the same time, the plurality of guide rods 222 lose the pressure of the transmission rod 321 and are reset under the tension of the spring 223, thereby releasing the restriction on the guardrail post so that the staff can extract it from the support cylinder 21 for maintenance.

[0038] In summary, the guardrail post fixing device of the embodiment of the present utility model can simplify the installation and disassembly processes, improve the disassembly and assembly efficiency, and thereby reduce the difficulty of installation and maintenance.
