Description

Technical Field

[0001] This utility model relates to the field of pipeline support technology, and specifically to a nail-free protective support rod. Background Technology

[0002] In modern construction safety management, edge protection for window openings and other similar locations is of paramount importance. Conventional protection methods include erecting steel pipes for protection or using nails to fix the protective steel pipes to both sides of the window opening. The former method, because the protective frame is erected on the ground, often gets moved during construction and is not promptly protected, resulting in a lack of protection. The latter method requires nails to fix the guardrails to both sides of the window opening, which can damage the structure during installation. Furthermore, the nails left after removal need to be cut off separately, and if not handled properly, they may rust and affect the finishing layer. Therefore, there is a need to provide a safety protection device that provides reliable safety protection, is easy to install and dismantle, and does not affect the structure or subsequent construction.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] See Figure 1 A nail-free protective support rod includes: a first pair of support rods 1, with a first pair of support plates 11 rotatably disposed at the end of the first pair of support rods 1, and an adjusting screw 3 fixedly installed at the end of the first pair of support rods 1 away from the first pair of support plates 11; and a second pair of support rods 2 disposed opposite to the first pair of support rods 1, with two supporting inner plates 26 disposed opposite to the end of the second pair of support rods 2, and an adjusting nut 4 fixedly installed between the two supporting inner plates 26, the adjusting nut 4 being threadedly connected to the adjusting screw 3, and a second pair of support plates 21 rotatably disposed at the end of the second pair of support rods 2 away from the first pair of support rods 1, wherein the relative distance between the first pair of support plates and the second pair of support plates is adjustable by rotating the second pair of support rods.

[0027] In this utility model, a preferred embodiment is as follows: Before installation, firstly, rotate the adjusting nut to rotate the first pair of support rods 1 and the second pair of support rods 2 toward each other, so that the length of the first pair of support rods 1 and the second pair of support rods 2 is reduced. Then, place the first pair of support rods 1 and the second pair of support rods 2 between the window openings. Then, rotate the adjusting nut 4 to rotate the first symmetrical rod and the second pair of support rods 2 away from each other, so that the length of the first pair of support rods 1 and the second pair of support rods 2 is expanded. The first pair of support plates 11 and the second pair of support plates 21 are pressed against the window side wall and tightened. The rotatable and adjustable first pair of support plates 11 and the second pair of support plates 21 can achieve a certain angle between the support rods and the support plates, which is applicable when the two side walls are not at the same height. When dismantling, the protective support rods can be disassembled by adjusting the adjusting nut 4 to reduce the length of the first pair of support rods 1 and the second pair of support rods 2.

[0028] Furthermore, the ends of the second pair of support rods 2 are provided with threaded holes corresponding to the adjusting screw 3, and the threaded holes are located between the two receiving inner plates 26. When the first pair of support rods 1 and the second pair of support rods 2 are rotated and adjusted, the adjusting screw 3 is rotatably inserted into the threaded hole, thereby saving space between the first pair of support rods 1 and the second pair of support rods 2, thereby minimizing the distance between the first pair of support plates 11 and the second pair of support plates 21.

[0029] Furthermore, two opposing receiving outer plates 16 are fixedly installed at the ends of the first pair of support rods 1 away from the first pair of support plates 11, and an adjusting screw 3 is provided between the two receiving outer plates 16, with a portion of the adjusting screw 3 extending outside the receiving outer plates 16. Preferably, a fixing hole is provided at the end of the first pair of support rods 1, and the adjusting screw 3 is fixed in the fixing hole.

[0030] Furthermore, the distance between the two outer receiving plates 16 is greater than the distance between the two inner receiving plates 26. During rotation, the inner receiving plate 26 is positioned within the outer receiving plate 16, thereby saving space between the first pair of support rods 1 and the second pair of support rods 2, thus minimizing the distance between the first pair of support plates 11 and the second pair of support plates 21.

[0031] Furthermore, the surface of the first pair of support plates 11 is fitted with anti-slip pads 5.

[0032] Furthermore, the surface of the second pair of support plates 21 is fitted with anti-slip pads 5.

[0033] Furthermore, the anti-slip mat 5 is uniformly covered with cylindrical protruding rubber anti-slip particles 51. The anti-slip mat 5 is made of rubber and can prevent sliding between it and the structural wall when it is pressed tightly against the structure on both sides, thus preventing the protective function from failing.

[0034] Furthermore, the first pair of support rods 1 is provided with two opposing first rotating connecting pieces at the end away from the adjusting screw 3, and the end of the first pair of support plates 11 is provided with a first rotating piece corresponding to the first rotating connecting piece. The first rotating piece is inserted between the two first rotating connecting pieces, and a first rotating shaft is inserted between the first rotating connecting piece and the first rotating piece.

[0035] Furthermore, the first rotating connecting piece has a first rotating hole corresponding to the first rotating shaft, the first rotating piece has a first mounting hole corresponding to the first rotating shaft, and the first rotating shaft is inserted into the first mounting hole and the first rotating hole.

[0036] Furthermore, the second pair of support rods 2 is provided with two opposing second rotating connecting pieces 25 at the end away from the adjusting screw 3. Rotating holes are formed on the rotating connecting pieces. The end of the second pair of support plates 21 is provided with a second rotating piece 23 corresponding to the second rotating connecting piece 25. The second rotating piece 23 is inserted between the two second rotating connecting pieces 25. A second rotating shaft 24 is inserted between the second rotating connecting piece 25 and the second rotating piece 23.

[0037] Furthermore, the second rotating connecting piece 25 has a second rotating hole corresponding to the second rotating shaft 24, and the second rotating piece 23 has a second mounting hole corresponding to the second rotating shaft 24. The second rotating shaft 24 is inserted into the second mounting hole and the second rotating hole.

[0038] The following describes the usage process of the nail-free protective support rod of this utility model.

[0039] Before installation, first turn the adjusting nut to rotate the first pair of support rods 1 and the second pair of support rods 2 closer to each other, so that the length of the first pair of support rods 1 and the second pair of support rods 2 is reduced. Then, place the first pair of support rods 1 and the second pair of support rods 2 between the window openings. Then, turn the adjusting nut 4 to rotate the first symmetrical rod and the second pair of support rods 2 away from each other, so that the length of the first pair of support rods 1 and the second pair of support rods 2 is expanded. Press the first pair of support plates 11 and the second pair of support plates 21 against the window side wall and tighten them. The rotatable and adjustable first pair of support plates 11 and the second pair of support plates 21 can make the support rods and the support plates form a certain angle, which is applicable when the two side walls are not at the same height. When removing, the protective support rods can be disassembled by adjusting the adjusting nut 4 to reduce the length of the first pair of support rods 1 and the second pair of support rods 2.

[0040] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description.
