Description
Technical Field
[0001] This utility model relates to a guardrail, and more particularly to a construction safety guardrail. Background Technology
[0002] In engineering construction, guardrails are mainly used as dividers, barriers, or temporary isolation barriers during accident handling to isolate and warn personnel at the construction site.
[0003] For example, a construction safety railing disclosed in Chinese Patent Publication No. CN222045287U belongs to the field of safety railing technology. It includes a base plate, with a first post and a second post fixedly connected to the top of the base plate. A first groove is formed on the surface of the first post, and damping bearings are fixedly connected to the inner walls of the grooves. A rotating shaft is rotatably connected to each of the two damping bearings, and a lead screw is fixedly connected to the opposite ends of the two shafts. A threaded plate is threaded onto the surface of the lead screw. A turntable is fixedly connected to the top of the rotating shaft. A placement frame is fixedly connected to the surface of the base plate, and a protective net is fixedly connected inside the placement frame. By rotating the turntable, the lead screw is rotated via the rotating shaft, thereby moving the threaded plate and extending / retracting the telescopic rod, adjusting the safety height of the railing. The installation of the protective net prevents objects from falling from heights, improving the safety performance of the railing. The existing construction guardrail has some problems. First, during daily use, the guardrail is inevitably damaged by impacts. Damaged components are difficult to replace individually, and the overall replacement cost is high. If it is used in a forced manner, the protective effect of the guardrail will be reduced. Second, the integrated design of the device requires a lot of space during transportation, which leads to difficulties in transportation and installation. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The horizontal bars of the fence are formed by telescopic poles. The length of the telescopic poles can be freely adjusted. The overall length of the fence can be adjusted according to the site conditions to enclose the construction site.
[0012] 2. By inserting the fixing rod into the mounting hole and passing it through the limiting hole, the connector is fixed inside the connector hole. Multiple components are spliced together to form a protective barrier. If the device is damaged during use, the damaged parts can be disassembled and replaced individually. Compared with the existing device, it does not require the whole device to be replaced, reducing the later maintenance cost. At the same time, the device is easy to store and transport when it is in a disassembled state in the early stage. Attached Figure Description

[0017] In this embodiment, the telescopic rod 2 is connected between two uprights 1 by inserting the connector 201 into the connector hole 101 to form the horizontal bar of the fence. Then, the square connector 403 is inserted into the connecting groove 104, and the support 4 is installed at the lower end of the upright 1. The support 4 is used to stably support the upright 1 to stand on the ground. By using the splicing method, if the device is damaged during use, the damaged parts can be disassembled and replaced individually. Compared with the existing device, it does not require the whole device to be replaced, reducing the later maintenance cost. At the same time, the length of the telescopic rod 2 can be freely adjusted, and the overall length of the fence can be adjusted according to the site conditions to enclose the construction site.
[0018] In order to fix the connector 201 in the connector hole 101, the device adopts the following technical solution: a limiting groove 102 is provided on the inner wall of the connector hole 101, a limiting protrusion 202 is fixedly connected to the outer wall of the connector 201, the limiting protrusion 202 and the limiting groove 102 cooperate with each other, a limiting hole 203 is provided in the connector 201, and the limiting hole 203 cooperates with the fixing rod 3.
[0019] By cooperating with the limiting groove 102 and the limiting protrusion 202, the angle at which the plug 201 is inserted into the plug hole 101 is limited. After the plug 201 is inserted into the plug hole 101, the limiting hole 203 will be aligned with the mounting hole 103. When the fixing rod 3 is inserted into the mounting hole 103, it will also be inserted into the limiting hole 203, thereby fixing the plug 201 inside the plug hole 101.
[0020] In order to fix the plug-in square head 403 in the connecting groove 104, the device adopts the following technical solution: a knob 301 is fixedly connected to the upper end of the fixing rod 3, and a connecting stud 302 is fixedly connected to the lower end of the fixing rod 3. The connecting stud 302 is threadedly engaged with the threaded sleeve block 404. The support member 4 includes a support foot 401, and the plug-in square head 403 is fixedly connected to the support foot 401. The support member 4 includes a fixing flange 402, and the plug-in square head 403 is fixedly connected to the fixing flange 402.
[0021] The knob 301 can rotate the fixing rod 3, which in turn rotates the connecting stud 302. After the plug-in square head 403 is inserted into the connecting groove 104, the connecting stud 302 is screwed into the threaded sleeve 404 located on the plug-in square head 403, thereby fixing the plug-in square head 403 inside the connecting groove 104. At the same time, the fixing rod 3 is fixed in the mounting hole 103. The fixing flange 402 is arched in shape and can be used to place it on the ground to stably support the upright 1.

[0022] The working principle and usage process of this utility model are as follows: When in use, the plug-in square head 403 needs to be inserted into the connecting groove 104. The support member 4 supports the upright 1 to stand on the ground. Then, the plug-in 201 is inserted into the plug-in hole 101. The fixing rod 3 is inserted into the mounting hole 103 and passes through the limiting hole 203 to fix the plug-in 201 in the plug-in hole 101. The fixing rod 3 on the knob 301 is rotated. The rotation of the fixing rod 3 can drive the connecting stud 302 to rotate, so that the connecting stud 302 is screwed into the threaded sleeve 404. Then, the plug-in square head 403 is fixed in the connecting groove 104, so that the upright 1, the support member 4, and the telescopic rod 2 are assembled together to form a guardrail.
