Description

Technical Field

[0001] The utility model relates to the technical field of road facilities, in particular to a temporary guardrail. Background Art

[0002] Temporary guardrails can also be called mobile fences, temporary isolation fences, and mobile safety fences. When roads are undergoing maintenance or to warn of road conditions, temporary guardrails can be used to surround them.

[0003] After searching, the applicant found that a Chinese patent disclosed "a temporary guardrail", and its publication (announcement) number is "CN220955015U". The patent mainly includes a guardrail leg, a railing connected to the guardrail leg, a suction cup provided under the guardrail leg, a sleeve provided on the suction cup, a slide groove provided in the sleeve, a warning sign connected to the railing, a first inclined plate connected to the guardrail leg, a sleeve connected to the sleeve, and a second inclined plate slidably connected to the sleeve. The temporary guardrail, through the cooperation between the first inclined plate, the second inclined plate and the spring, enables the guardrail leg and the suction cup to achieve the function of rapid assembly, and the guardrail leg can be adsorbed to the road through the suction cup. However, the above-mentioned prior art is not flexible enough in adjusting the temporary guardrail, is not convenient to move, and cannot be fixed on uneven road surfaces. For this reason, we propose a temporary guardrail. Utility Model Content

[0006] As a further solution of the present invention: a plurality of railings are provided, and the plurality of railings are alternately and fixedly arranged.

[0007] As a further solution of the present invention: the length of the threaded rod is smaller than the depth of the threaded hole.

[0008] As a further solution of the present invention: the connecting rod is arranged in an L shape, and an end of the connecting rod away from the guardrail body is provided with a mounting hole suitable for fixing with a fixing bolt.

[0009] As a further solution of the present invention: a non-slip pad is provided on the surface of one side of the counterweight chassis away from the threaded rod.

[0010] As a further solution of the present invention: the counterweight chassis does not contact the guardrail body.

[0011] As a further solution of the present invention: a reflector is fixedly installed on the top of the fixing column.

[0012] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model installs a threaded rod through the thread inside the fixed column. When the guardrail body needs to be installed, the threaded rod is screwed out so that the counterweight chassis contacts the ground. The anti-slip pad makes the installation of the guardrail body more stable. When the ground is uneven, the threaded rod can be screwed out to different degrees to make the entire guardrail body stable, which is convenient for installation. When the guardrail body needs to be moved, the threaded rod is screwed into the threaded hole of the fixed column, the counterweight chassis is separated from the ground, and the roller contacts the ground, which is easy to move.

[0014] 2. The utility model provides a mounting hole at one end of the connecting rod, which facilitates the installation and fixation of multiple guardrail bodies through fixing bolts. The setting of the railing prevents people from climbing, and a reflector is provided on the top of the fixing column to serve as a warning when vehicles are driving at night.

[0015] Other advantages, objectives and features of the present invention will be described in part in the following description and will be apparent to those skilled in the art based on an examination of the following or may be learned from the practice of the present invention.

[0024] In one embodiment of the present invention, a plurality of railings 2 are provided, and the plurality of railings 2 are alternately and fixedly arranged.

[0025] In one embodiment of the present invention, the length of the threaded rod 8 is smaller than the depth of the threaded hole.

[0026] In one embodiment of the present invention, the connecting rod 5 is arranged in an L-shape, and an end of the connecting rod 5 away from the guardrail body 1 is provided with a mounting hole 7 suitable for fixing with a fixing bolt.

[0027] In one embodiment of the present invention, a non-slip pad is provided on the surface of the counterweight chassis 9 away from the threaded rod 8 .

[0028] In one embodiment of the present invention, the counterweight chassis 9 does not contact the guardrail body 1 .

[0029] In one embodiment of the present invention, a reflector 6 is fixedly mounted on the top of the fixing column 4 .

[0030] Example 1, please refer to the attached Figure 1 -Attached Figure 4 A threaded hole is provided at the bottom axis of the fixing column 4, and a threaded rod 8 is threadedly connected to the threaded hole. The length of the threaded rod 8 is less than the depth of the threaded hole. The threaded rod 8 can be screwed into the threaded hole, and the threaded rod 8 can be completely retracted in the threaded hole;

[0031] The connecting rod 5 is arranged in an L shape, and a mounting hole 7 suitable for fixing with a fixing bolt is opened at one end of the connecting rod 5 away from the guardrail body 1. When multiple guardrail bodies 1 are connected, they can be fixed together by passing the fixing bolt through the mounting hole 7.

[0032] Example 2, please refer to the attached Figure 1 -Attached Figure 4 , a non-slip pad is provided on the side surface of the counterweight chassis 9 away from the threaded rod 8, so that the guardrail body 1 is more stable during installation;

[0033] A reflector 6 is fixedly mounted on the top of the fixed column 4. When the vehicle is driving at night, the reflector 6 can serve as a warning and improve safety.

[0034] Specifically, by threading the threaded rod 8 inside the fixed column 4, when the guardrail body 1 needs to be installed, the threaded rod 8 is screwed out so that the counterweight chassis 9 contacts the ground. Due to the provision of the anti-slip pad, the installation of the guardrail body 1 is more stable. For uneven ground, the threaded rod 8 can be screwed out to different degrees to make the entire guardrail body 1 in a stable state, which is convenient for installation. When the guardrail body 1 needs to be moved, the threaded rod 8 is screwed into the threaded hole of the fixed column 4, the counterweight chassis 9 is separated from the ground, and the roller 3 contacts the ground, which is easy to move.

[0035] Specifically, by setting a mounting hole 7 at one end of the connecting rod 5, it is convenient to install and fix multiple guardrail bodies 1 through fixing bolts. The setting of the railing 2 prevents people from climbing, and a reflector 6 is set on the top of the fixing column 4 to serve as a warning when vehicles are driving at night.

[0036] Working principle:

[0037] First, when the guardrail body 1 needs to be installed, the threaded rod 8 is unscrewed so that the counterweight chassis 9 contacts the ground. The setting of the anti-slip pad makes the installation of the guardrail body 1 more stable. For uneven ground, the threaded rod 8 can be unscrewed to varying degrees to make the entire guardrail body 1 in a stable state. When the guardrail body 1 needs to be moved, the threaded rod 8 is screwed into the threaded hole of the fixing column 4, the counterweight chassis 9 is separated from the ground, and the roller 3 contacts the ground. A mounting hole 7 is set at one end of the connecting rod 5 to facilitate the installation and fixation of multiple guardrail bodies 1 by fixing bolts. The railing 2 is set to prevent people from climbing, and a reflector 6 is set on the top of the fixing column 4 to serve as a warning when vehicles are driving at night. At this point, the entire work process is completed.
