[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1-3, A prefabricated bridge guardrail that is easy to assemble in this embodiment includes two vertical rods 1, two crossbars 2 disposed between the two vertical rods 1, and six railings 3 fixedly connected between the two crossbars 2. An installation component 4 including four that extends to the outside of the vertical rod 1 and fixes the two crossbars 2 is provided inside the vertical rod 1. Two limiting components 5 for limiting the bottom crossbar 2 are provided between the two vertical rods 1. The installation component 4 includes a fixed cylinder 41 fixedly connected to the outside of the vertical rod 1 and a mounting seat 42 fixedly connected to one end of the top crossbar 2 close to the right vertical rod 1. A pull rod 43 is slidably connected inside the fixed cylinder 41. One end of the pull rod 43 away from the fixed cylinder 41 is fixedly connected to a handle 44. A spring 45 is fixedly connected to the outside of the pull rod 43. One end of the pull rod 43 away from the handle 44 is fixedly connected to a push rod 46 that penetrates the right vertical rod 1 and extends into the mounting seat 42.

[0025] Due to the elastic force of the spring 45, since the pull rod 43 remains stationary inside the fixed cylinder 41, the push rod 46 extends into the mounting seat 42, facilitating the fixation of the crossbar 2 and the railing 3. By pulling the handle 44 to drive the linear movement of the pull rod 43, the push rod 46 is disengaged from the inside of the mounting seat 42, facilitating the disassembly of the crossbar 2 and the railing 3, achieving the advantage of being easy to use.

[0026] Among them, a moving hole adapted to the pull rod 43 is opened inside the fixed cylinder 41, and the outer diameter of the pull rod 43 is adapted to the inner diameter of the moving hole.

[0027] It should be noted that the handle 44 is in a C shape, and an anti-slip rubber is sleeved outside the handle 44. By setting the anti-slip rubber, the anti-slip effect of the handle 44 is improved.

[0028] In addition, the push rod 46 is movably connected to the inside of the vertical rod 1, and a card slot adapted to the push rod 46 is opened inside the mounting seat 42. The outer diameter of the push rod 46 is adapted to the inner diameter of the card slot.

[0029] Moreover, all six railings 3 are solid cuboids, and the six railings 3 are evenly distributed between the two crossbars 2.

[0030] In this embodiment, the limiting component 5 includes a fixed seat 51 fixedly connected to the outside of the vertical rod 1. An insertion block 52 is inserted into the fixed seat 51. One end of the insertion block 52 away from the fixed seat 51 is fixedly connected to the bottom of the bottom crossbar 2. By setting the fixed seat 51 and the insertion block 52, the stability during the installation of the crossbar 2 and the railing 3 is improved.

[0031] Among them, the insertion block 52 is a solid cuboid, and a plugging slot adapted to the insertion block 52 is opened inside the fixed seat 51. The outer diameter of the insertion block 52 is adapted to the inner diameter of the plugging slot.

[0032] Embodiment 2:

[0033] See also Figure 1-3 On the basis of the first embodiment, the embodiment includes a positioning rod 6 inserted into the mounting seat 42 and the push rod 46. The mounting seat 42 and the push rod 46 are both provided with positioning holes. The outer diameter of the positioning rod 6 matches the inner diameter of the positioning hole. By providing the positioning rod 6, the stability of the push rod 46 when fixing the mounting seat 42, the crossbar 2 and the railing 3 is improved, achieving the advantage of strong practicality.

[0034] The positioning rods 6 are solid cylinders, and there are six positioning rods 6 .

[0035] The above technical solution improves the stability of the push rod 46 when fixing the mounting seat 42 and the cross bar 2, achieving the advantage of strong practicality.

[0036] The working principle of the above embodiment is:

[0037] When in use, the insert block 52 is extended to the interior of the fixing seat 51 to perform preliminary fixation on the cross bar 2 and the railing 3 during installation. Through the elastic force of the spring 45, since the pull rod 43 remains stationary inside the fixing tube 41, the push rod 46 is extended to the interior of the mounting seat 42 to fix the cross bar 2 and the railing 3. By pulling open the handle 44 to drive the pull rod 43 to move linearly, the push rod 46 is disengaged from the interior of the mounting seat 42, thereby disassembling the cross bar 2 and the railing 3. By setting the positioning rod 6, the push rod 46 can stably fix the mounting seat 42 and the cross bar 2.
