Description

Technical Field

[0001] The utility model relates to the technical field of anti-movement devices, in particular to a vertical hole opening protection anti-movement device. Background Art

[0002] A construction site is a potentially dangerous place, involving multiple risk factors such as working at heights, using electrical equipment, operating machinery, etc. If proper safety measures are not taken, workers and other related personnel may face serious injuries or even life threats.

[0003] There are many vertical openings in building construction, such as stair openings, elevator openings, fire openings, etc. These vertical openings cannot usually be immediately blocked during construction, so they need to be protected. Existing protection tools generally use steel plates or guardrails. In order to prevent the steel plates or guardrails from being moved by people during the steel protection process, it is necessary to fix the steel plates or guardrails to the wall with steel wires to prevent unnecessary passage of non-construction personnel.

[0004] However, during the construction process, non-construction personnel often remove the steel wire to move the guardrail for easy passage or other reasons. Usually, non-construction personnel will not restore the steel wire after removing it, resulting in the guardrail or steel plate not being fixed to the wall, thus leaving a safety hazard. Therefore, it is necessary to provide a vertical opening protection anti-movement device that is not easy to disassemble. Utility Model Content

[0025] Example

[0026] like Figure 1-4 As shown, the utility model provides a vertical hole protection anti-movement device, including two groups of anti-movement mechanisms 1 and adjustment components 2 that are symmetrically arranged, the anti-movement mechanism 1 includes a screw 11 and a nut 12, the nut 12 is threadedly arranged on the screw 11, and the nut 12 can be a hexagonal nut. Limiting holes 17 are arranged at equal distances on the nut 12. A screw head 13 is arranged at one end of the screw 11 away from the nut 12, and a hexagonal groove is arranged on the side of the screw head 13 away from the nut 12, so that when someone wants to disassemble the device, it must be disassembled by using specific tools, which increases the difficulty for non-staff to disassemble the device.

[0027] A fixing assembly 14 is provided at the connection between the nut 12 and the screw rod 11, and the fixing assembly 14 includes a limit plate 141 and a fixing plate 142. The limit plate 141 is threadedly provided on the screw rod 11, and one end of the fixing plate 142 is fixedly connected to one end of the limit plate 141, and the fixing plate 142 is an L-shaped fixing plate. A mounting hole 143 is provided on the limit plate 141, and an internal thread is provided in the mounting hole 143. An external thread is provided on the surface of the nut 12, and the internal thread is adapted to the external thread. The nut 12 is connected to the mounting hole 143 by threads, and the fixing plate 142 can be fixedly connected to the screw rod 11 through the nut 12.

[0028] A soft pad 15 is arranged on one side of the nut 12 away from the screw rod head 13. The soft pad 15 is sleeved on the screw rod 11, and the soft pad 15 includes but is not limited to a rubber pad.

[0029] A second fixing assembly 16 is provided at the connection between the screw head 13 and the screw 11, and the second fixing assembly 16 is threadedly connected to the screw 11. The second fixing assembly 16 includes a second limiting plate 161, a second fixing plate 162 and a third limiting plate 163. The second limiting plate 161 is threadedly provided on the screw 11, and the two ends of the second fixing plate 162 are respectively fixedly connected to the second limiting plate 161 and the third limiting plate 163. The second fixing plate 162 is an L-shaped fixing plate.

[0030] The adjustment assembly 2 includes an adjustment nut 21 and a limit rod 22, and the limit rod 22 is arranged at an equal distance on one side of the adjustment nut 21. The size of the limit hole 17 is slightly larger than the limit rod 22, so that the limit rod 22 can be inserted into the limit hole 17 without too much room for movement. The adjustment nut 21 can be a hexagonal nut, which is convenient for rotation by a wrench. After the limit rod 22 is inserted into the limit hole 17, the position of the nut 12 on the screw rod 11 can be adjusted by turning the adjustment nut 21 with a wrench. When the nut 12 is rotated by the adjustment nut 21, the cushion 15 is arranged between the nut 12 and the adjustment nut 21. After the nut 12 is screwed into the mounting hole 143, the cushion 15 returns to its original state in the mounting hole 143 due to elastic force, thereby shielding the nut 12, which can ensure that non-staff cannot easily loosen the nut 12. At the same time, non-staff must use the adjustment assembly 2 to loosen the nut 12, which increases the difficulty of disassembly of the device and prevents the moving guardrail.

[0031] The specific connection methods of each part all adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0032] When the vertical opening protection and anti-movement device of this embodiment is in use, the column 4 of the railing 3 is set between the fixing plate 2 162 and the limiting plate 3 163, and then the screw head 13 is rotated by a wrench to adjust the position of the fixing component 2 16 on the screw 11, the fixing plate 1 142 is pressed against one side of the wall 5, the cushion 15 is set between the adjusting nut 21 and the nut 12, the limiting rod 22 is inserted into the limiting hole 17, and the adjusting nut 21 is rotated by a wrench to drive the nut 12 to rotate on the screw 11, and after the nut 12 is screwed into the mounting hole 143, the adjusting nut 21 is taken out.

[0033] Therefore, the utility model adopts the vertical opening protection and anti-movement device of the above-mentioned structure, and a hexagonal groove is arranged on the screw head. When disassembling, it needs to be disassembled by using specific tools, and the nut can only be removed by adjusting the assembly, which increases the difficulty of disassembly of the device, thereby ensuring that non-staff cannot easily separate the guardrail from the wall.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
