[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0019] The utility model comprises a guardrail 1, a bottom plate 2 and a connecting and telescopic mechanism 3.

[0020] The bottom plate 2 is fixedly mounted on the bottom of the guardrail 1. The guardrail 1 is a plurality of guardrails, which are arranged in sequence from left to right.

[0021] The connecting telescopic mechanism 3 is located between two adjacent left and right fences 1 to connect the two fences 1. The connecting telescopic mechanism 3 includes a sliding plate 301, a connecting slide plate 302, a magnetic plate 303, a left sliding rod 304, a tension spring 305, a protective shell 306, a right sliding rod 307 and a connecting sleeve 308.

[0022] The sliding plate 301 is slidably mounted inside the connecting sleeve 308. A magnetic plate 303 is embedded and fixed on one side of the inner wall of the connecting sleeve 308, and the sliding plate 301 and the magnetic plate 303 are arranged to attract each other. The sliding plate 301 can be made of magnetic material, and in this case, the sliding plate 301 and the magnetic plate 303 are arranged to attract each other with corresponding opposite poles.

[0023] The left end of the connecting slide plate 302 is fixedly connected to one side of the sliding plate 301 ; a sliding groove is provided at the right end of the connecting sleeve 308 , and the right end of the connecting slide plate 302 passes through the sliding groove and extends to the outside of the connecting sleeve 308 .

[0024] A left slot 101 is provided on the left side of the fence 1, and a right slot 102 is provided on the right side. The left end of the connecting sleeve 308 is inserted into the left fence 1 and fixed, specifically, the left end of the connecting sleeve 308 is inserted into the right slot 102 of the left fence 1 and fixed. The right end of the connecting slide 302 is inserted into the right fence 1 and fixed, specifically, the right end of the connecting slide 302 is inserted into the left slot 101 of the right fence 1 and fixed.

[0025] A sliding hole is provided on one side of the guardrail 1, and the left sliding rod 304 and the right sliding rod 307 slide through the sliding hole to extend to the inside of the two slots, so that the left sliding rod 304 and the right sliding rod 307 are slidably installed on the guardrail 1. The left sliding rod 304 is plugged and connected with the guardrail 1 and the connecting slide 302 to fix the guardrail 1 and the connecting slide 302 together; the right sliding rod 307 is plugged and connected with the guardrail 1 and the connecting sleeve 308 to fix the guardrail 1 and the connecting sleeve 308 together; further, the outer walls of the connecting sleeve 308 and the connecting slide 302 are provided with mounting holes, and the left sliding rod 304 and the right sliding rod 307 respectively plug and fix the connecting sleeve 308 and the connecting slide 302 with the guardrail 1 through the mounting holes.

[0026] Tension springs 305 are connected to the outer walls of the left sliding rod 304 and the right sliding rod 307. One end of the tension spring 305 away from the left sliding rod 304 and the right sliding rod 307 is connected to the outer wall of the guardrail 1. The tension spring 305 allows the left sliding rod 304 and the right sliding rod 307 to be elastically slidably installed on the guardrail 1.

[0027] The protective shell 306 is fixed to the left sliding rod 304 and the right sliding rod 307 , and covers the left sliding rod 304 , the right sliding rod 307 and the tension spring 305 .

[0028] The working method of the utility model is:

[0029] When the staff is carrying out safety protection for the construction of the building project, they place multiple guardrails 1 at the place where protection is required; when protecting it, pull the two guardrails 1 so that the distance between the guardrails 1 can be slid and adjusted according to the sliding action between the connecting slide plate 302 and the connecting sleeve 308, and use the sliding plate 301 and the magnetic plate 303 to make the connecting slide plate 302 and the connecting sleeve 308 slide and fix. Through the setting of this structure, the distance between the multiple guardrails 1 can be slid and adjusted to increase the protection area of ​​the multiple guardrails 1, thereby improving the use effect of this device; it should be noted that the attraction between the sliding plate 301 and the magnetic plate 303 is less than the force of the staff manually pulling the guardrail 1.

[0030] After long-term use, when the guardrail 1 is damaged, the protective shell 306 is pulled toward the outside of the guardrail 1, which correspondingly drives the two sliding rods to disengage from the mounting holes on the outer wall of the connecting sleeve 308 and the connecting slide plate 302, and then the guardrail 1 is slid and disengaged from the connecting sleeve 308 and the connecting slide plate 302. Through the setting of this structure, based on the plug-in effect of the two sliding rods, the installation operation between the guardrail 1 and the connecting sleeve 308 and the connecting slide plate 302 is simplified. Compared with the fixed setting, it is convenient for the staff to disassemble and replace the damaged guardrail 1, and correspondingly reduces the operating steps of the staff using this device, thereby improving the protection efficiency of the staff using this device for safety protection of construction projects. At the same time, the plug-in effect of the slot and the connecting sleeve 308 and the connecting slide plate 302 can make the installation of this device more convenient, thereby improving the use effect of this device.

[0031] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
