Description

Technical Field

[0001] The utility model relates to the technical field of isolation fences, in particular to an isolation fence which is convenient for stable placement. Background Technique

[0002] Highway bridge engineering refers to all the work of planning, designing, constructing, maintaining, and repairing structures that span water areas, valleys, and all traffic channels. In order to ensure the safety of vehicles and pedestrians during the construction process of highway bridges, isolation fences will be placed at the construction locations for isolation.

[0003] Most of the existing isolation fences are in a plate-like structure. Since most of the construction sections of highway bridges are open spaces, after the plate-like isolation fences are placed, due to their insufficient stability, they are easily blown down by the wind, resulting in the inability to use the isolation fences normally. Content of the Utility Model

[0004] The purpose of the utility model is to provide an isolation fence which is convenient for stable placement, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an isolation fence which is convenient for stable placement, including a top beam, and first grooves are opened on the side walls on both sides of the top beam. The inside of the first grooves is hinged with isolation plates through first pins, and the first pins pass through the top beam and the isolation plates.

[0006] Preferably, second pins are inserted through the side walls at one ends of the two isolation plates away from the first pins, and hinge frames are sleeved on the shaft walls at the ends of the second pins extending out of the isolation plates.

[0007] Preferably, a second groove is opened at the bottom of the isolation plate, and an extension plate is sleeved on the shaft wall of the second pin located inside the second groove.

[0008] Preferably, adjacent two hinge frames are hinged through a third pin.

[0009] Preferably, a limiting plate is arranged above the connection of adjacent two hinge frames, and the limiting plate is fixedly connected to the top of one of the hinge frames.

[0010] Compared with the prior art, the beneficial effects of the utility model are: the isolation fence which is convenient for stable placement of the utility model has a simple structure and is convenient to use. By the top beam and multiple hinge frames, it is ensured that the two isolation plates are in an equilateral triangle structure when in use. The stability of the triangle is good, and the inclined isolation plates are not easily blown down by the wind, making the isolation fence more stable when placed; and the isolation fence can be folded, which is convenient for the storage and transportation of the isolation fence.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4 , the present utility model provides a technical solution: a partition fence that is convenient for stable placement, including a top beam 1. First grooves 2 are opened on the side walls on both sides of the top beam 1. A partition board 4 is hinged inside the first groove 2 through a first pin shaft 3, and the first pin shaft 3 passes through the top beam 1 and the partition board 4.

[0018] Second pin shafts 6 are inserted through the side walls at one end of the two partition boards 4 away from the first pin shaft 3. Hinge frames 8 are sleeved on the shaft walls at one end of the second pin shafts 6 extending out of the partition boards 4, and the hinge frames 8 can limit the unfolding angle of the two partition boards 4.

[0019] A second groove 5 is opened at the bottom of the partition board 4. An extension plate 7 is sleeved on the shaft wall of the second pin shaft 6 located inside the second groove 5. The extension plate 7 can effectively assist in supporting the unfolded partition board 4 and can effectively make the partition fence more stable.

[0020] Adjacent two hinge frames 8 are hinged through a third pin shaft 9, and the third pin shaft 9 enables the adjacent two hinge frames 8 to fold and flip relative to each other.

[0021] Above the connection of two adjacent articulated frames 8, a limit plate 10 is provided, and the limit plate 10 is fixedly connected to the top of one of the articulated frames 8. The limit plate 10 can effectively limit the flipping angle of the articulated frame 8, so that the maximum flipping angle of the two articulated frames 9 is 180 degrees.

[0022] Specifically, in the initial state, as shown in the appendix Figure 2 At this time, the isolation plates 4 on both sides of the top beam 1 are in a folded state, and the articulated frame 8 is also in a folded state. The volume of the isolation fence is small, which is convenient for the storage and transportation of the isolation fence.

[0023] During use, the two isolation plates 4 are respectively flipped and unfolded towards both sides with the first pin shaft 3 on the top beam 1 as the axis. During the unfolding process of the isolation plates 4, the articulated frames 8 at their ends can be driven to flip and unfold. The articulated frames 8 are flipped to a horizontal state. At this time, the extension plate 7 is flipped with the second pin shaft 6 as the axis, as shown in the appendix Figure 1 At this time, the isolation fence can be placed on the ground. A structure similar to an isosceles triangle is formed between the two isolation plates 4 and the articulated frames 8. The stability of the triangle is good, and the inclined isolation plates 4 are not easily blown down by the wind, making the isolation fence more stable when placed.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
