Description

Technical Field

[0001] The utility model relates to the technical field of safety fences for construction sites, and particularly relates to a splicing type guardrail. Background Art

[0002] A guardrail, that is, a fence, refers to an "anti-collision fence" for industrial use. Guardrails are mainly used for the protection of personal safety and equipment and facilities in places such as residences, roads, commercial areas, and public places. Guardrails can be seen everywhere in our lives. According to different heights, the price per meter of the guardrail will also be different. The use of guardrails during construction in construction sites is also very important;

[0003] For the existing splicing type guardrails used in construction site construction, when assembling and splicing the guardrails during use, two guardrails are connected by bolts;

[0004] The traditional splicing type guardrails have the following problems: when performing splicing operations, not only additional tools such as screwdrivers are needed, but also multiple bolt rotation operations are required, which brings inconvenience to the assembly and splicing of the guardrails and affects the construction progress. Therefore, we propose a splicing type guardrail. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: a splicing type guardrail, including a first railing, a plugging mechanism and a fixing mechanism;

[0007] The first railing: a second railing is arranged on its right side. Slots are respectively opened at the upper and lower ends of the left side surface of the second railing. The insertion strips at the upper and lower ends of the right side surface of the first railing are respectively slidably connected with the adjacent slots;

[0008] The plugging mechanism: it includes a chute, a sliding plate and a plug. Chutes are respectively opened inside the insertion strips. The sliding plates are respectively slidably connected inside the chutes. The front side surfaces of the sliding plates are respectively fixedly connected with plugs. Limit holes corresponding to the upper and lower parts are opened on the front side surface of the left end of the second railing. The plugs are respectively installed in cooperation with the adjacent limit holes;

[0009] The fixing mechanism: it is respectively arranged on the inner side surface of the left end of the second railing, which is convenient for quickly splicing two guardrails, can be spliced without the aid of tools, avoids affecting the construction progress of the construction site, and effectively fixes the two guardrails at the same time, so that the guardrail has better safety.

[0010] Further, the plugging mechanism further includes telescopic rods and springs. Telescopic rods corresponding to the left and right are fixedly connected between the rear side wall of the chute and the rear end of the sliding plate respectively, and springs are sleeved outside the telescopic rods respectively, which is convenient for rebounding.

[0011] Further, the plugging mechanism further includes vertical plates, threaded holes and first threaded rods. At the upper and lower ends of the front side of the second railing, vertically symmetric vertical plates are provided respectively. The vertical plates are located on the left and right sides of the limiting holes respectively. Threaded holes are respectively formed in the vertical plates and the inner parts of the plug blocks, and first threaded rods are respectively threadedly connected to the inner parts of the threaded holes to provide fixation.

[0012] Further, the plugging mechanism further includes a dial. The left ends of the first threaded rods are fixedly connected with dials respectively, which is convenient for installation.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present splicing guardrail has the following advantages:

[0017] 1. When a safety fence is needed at a construction site, first align the two insertion strips at the right end of the first railing with the two insertion slots at the left end of the adjacent second railing, and then use the chute to insert the insertion strips into the inside of the insertion slots respectively. When the insertion strips are inserted into the insertion slots, the plug blocks are respectively contracted inside the chute under the pressure of the insertion slots. Then the insertion strips continue to slide inside the adjacent insertion slots respectively. When the plug blocks slide to the limiting holes respectively, the plug blocks are respectively released from the pressure, and the plug blocks are respectively ejected under the rebounding action of the telescopic rods and the springs to be inserted into the adjacent limiting holes respectively.

[0018] 2. Next, to make the guardrail have a better fixing effect, rotate the dials respectively. The rotation of the dials will drive the second threaded rods to rotate respectively, and then the second threaded rods will move towards each other in the internal threads of the internal threaded cylinders respectively. Then, rotate the second threaded rods into the internal part of the jacks respectively. Then, thread the external bolts into the threaded holes on the dials respectively to make the locking bolts tightly press against the inner side of the second railing, lock and fix the dials, so that the first railing and the second railing have a better fixing effect, effectively fix the two guardrails, and make the guardrail for construction site have better safety.

The left ends of the first threaded rods 48 are respectively fixedly connected with the dials 49. When the safety fence needs to be used at the construction site, first align the two inserting strips at the right end of the first railing 1 with the two slots 3 at the left end of the adjacent second railing 2, and then insert the inserting strips into the inside of the slots 3 through the chutes 41. When the inserting strips are inserted into the slots 3, the plug blocks 45 are respectively contracted inside the chutes 41 under the pressure of the slots 3. Then the inserting strips respectively continue to slide inside the adjacent slots 3. When the plug blocks 45 respectively slide to the limiting holes, the plug blocks 45 respectively break away from the pressure. The plug blocks 45 are respectively ejected by the resilience of the telescopic rods 42 and the springs 43 and are respectively inserted into the adjacent limiting holes.

Then, align the threaded holes 47 on the vertical plates 46 with the threaded holes 47 on the insertion blocks 45. Then, the dials 49 are respectively rotated. The rotation of the dials 49 will respectively drive the first threaded rods 48 to rotate. The first threaded rods 48 are respectively threadedly connected with the threaded holes 47, thus realizing rapid splicing. Then, in order to make the guardrail for construction site construction have a better fixing effect, the dials 54 are respectively rotated. The rotation of the dials 54 will respectively drive the second threaded rods 53 to rotate, and then the second threaded rods 53 will respectively move inwards in the internal thread cylinders 52 in a threaded manner. Then, the second threaded rods 53 are respectively rotated into the inside of the jacks 51.
