TECHNICAL FIELD

[0001] The utility model relates to the technical field of railings, in particular to a spacing adjustable railing. BACKGROUND

[0002] In the process of electric power construction, there are dangerous facilities such as high-voltage wires, which may cause electric shock and other injuries to nearby personnel. Using temporary guardrails can isolate non-construction areas from construction areas, preventing unrelated personnel from entering and thus reducing safety risks. At the same time, construction areas often involve large mechanical equipment, building materials, and tools, etc. If not effectively isolated, it is easy to cause chaos and accidents. Temporary guardrails can effectively separate different areas and ensure the orderly operation of the construction site.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1

[0034] like Figures 1-3 As shown, this embodiment proposes:

[0035] An adjustable-spacing fence includes:

[0036] Two symmetrically arranged columns 1 are provided, and scissor bars 2 are symmetrically installed between the two columns 1. The top ends of both sides of the scissor bars 2 are rotatably connected to the side walls of the corresponding columns 1. Limiting sliders 5 are rotatably installed on the bottom ends of both sides of the scissor bars 2. The limiting sliders 5 are slidably installed on the corresponding columns 1.

[0037] The outer shell 3 is fixed to the side wall of the column 1 and is sleeved on the outside of the scissor bar 2. A limiting mechanism 7 is installed between the two corresponding outer shells 3.

[0038] Mounting base 8 is installed at the bottom end of column 1.

[0039] A limiting groove 4 is provided on the side wall of column 1, and the limiting slider 5 is slidably installed in the limiting groove 4.

[0040] In this embodiment, the scissor bar 2 is installed in the limiting groove 4 of the column through the limiting slider 5. Due to its special structure, the scissor bar 2 can adjust the distance between the two columns 1, thereby achieving the purpose of adjusting the length of the fence. At the same time, the outer shell 3 can store the scissor bar 2 inside the outer shell 3 when the fence is not in use, and the two adjacent outer shells 3 are fixed by the limiting mechanism 7, so that the fence is easy to store and carry. The mounting base 8 can easily install the fence in a designated position.

[0041] Example 2

[0042] like Figures 2-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes:

[0043] A connecting mechanism 6 is installed on the top of one side column 1, and a limiting hole 11 is opened on the top wall of the other side column 1.

[0044] A mounting groove 10 is provided at the top of one side column 1, and the connecting mechanism 6 is installed in the mounting groove 10.

[0045] The connecting mechanism 6 includes a sliding column 61, which is slidably installed in the mounting groove 10. A first spring 62 is fixed at the bottom of the sliding column 61, and a cross plate 63 is fixed at the top of the sliding column 61.

[0046] The first spring 62 is installed in the mounting groove 10, and the bottom end of the first spring 62 is fixedly connected to the bottom wall of the mounting groove 10.

[0047] A positioning pin 64 that mates with the limiting hole 11 is fixed to the bottom wall of the horizontal plate 63 away from the sliding pin 61.

[0048] In this embodiment, the connecting mechanism 6 facilitates the connection of the posts 1 between two adjacent fence groups, thereby making it easy to assemble the device into a large fence for use. When using the connecting mechanism 6, the horizontal plate 63 is pulled upward. At this time, the horizontal plate 63 drives the first spring 62 to stretch through the sliding column 61, and at the same time, the positioning column 64 on the other side moves upward until the posts 1 between the two adjacent fence groups can fit together. At this time, the horizontal plate 63 is released, and under the action of the first spring 62, the positioning column 64 is inserted into the corresponding limiting hole 11, completing the connection between the two fence groups.

[0049] The limiting mechanism 7 comprises a movable plate 71 and a threaded column 72, the movable plate 71 being rotatably installed on the side wall of one side shell 3;

[0050] The threaded column 72 is fixed on the side wall of the other side shell 3, and a threaded sleeve 73 is screwed on the threaded column 72.

[0051] The movable plate 71 is provided with a groove 9 matched with the threaded column 72.

[0052] The mounting seat 8 comprises a seat body 81, the top wall of the seat body 81 is provided with a clamping groove 82, and two symmetrical sliding grooves 83 are formed on the two sides of the clamping groove 82;

[0053] A clamping plate 84 is slidably installed in the sliding groove 83.

[0054] A plurality of second springs 85 are symmetrically fixed between the side wall of the clamping plate 84 and the side wall of the sliding groove 83, and a chamfer is arranged on the clamping end of the clamping plate 84.

[0055] In the embodiment, the limiting mechanism 7 can fix the two adjacent side shells 3 when the fence is not needed to be used, and the mounting seat 8 can conveniently install the fence at a specified position. When the limiting mechanism 7 is used, first, the scissors lever 2 is folded and stored in the side shell 3, so that the two side shells 3 are attached to each other, the movable plate 71 is rotated, so that the groove 9 on the movable plate 71 is clamped on the threaded column 72, then the threaded sleeve 73 is rotated, so that the threaded sleeve 73 tightly presses the movable plate 7 on the outer wall of the side shell 3, and the fixing between the two side shells 3 is completed. When the mounting seat 8 is used, the bottom end of the stand column 1 is inserted into the clamping groove 82, the bottom end of the stand column 1 first contacts the chamfer position on the clamping plate 84, and the stand column 1 continues to move downward and presses the clamping plate 84 into the sliding groove 83, and when the stand column 1 is completely clamped in the clamping groove 82, the clamping plate 84 is clamped on the outer side of the stand column 1 under the action of the second spring 85, thereby limiting the stand column 1.

[0056] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
