Specific embodiments

[0021] The following specific embodiments illustrate the implementation manners of the present utility model. Those familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0022] The present utility model discloses a building construction guardrail, as Figures 1-4 shown, including a telescopic guardrail 1, which is used to warn the public during the building construction process, and the telescopic guardrail 1 can be telescoped so as to adjust the length of the telescopic guardrail 1 according to actual needs.

[0023] Both the left and right sides of the telescopic guardrail 1 are fixedly connected with connecting columns 2, and both the front and rear sides of the two connecting columns 2 are fixedly connected with fixing frames 3. Movable support rods 4 are rotatably connected inside the four fixing frames 3, and the movable support rods 4 can rotate around the fixing frames 3 as the center.

[0024] Moreover, a rotation limiting component 7 is provided between the movable support rod 4 and the fixed frame 3. Connecting frames 5 are provided at one ends of the four movable support rods 4 away from the fixed frame 3, and the movable support rod 4 is hinged to the connecting frame 5. The outer bottom surfaces of the four connecting frames 5 are fixedly connected with support bottom plates 6. When the movable support rod 4 rotates, it will drive the support bottom plate 6 to rotate, so as to flip the movable support rod 4 and the support bottom plate 6 until the support bottom plate 6 contacts the ground. Fixed plates 8 are provided on the sides of the two connecting columns 2 away from each other.

[0025] The rotation limiting component 7 includes two circular tubes 701 embedded in the movable support rod 4. Two moving plates 702 are slidably connected inside the two circular tubes 701, and the two moving plates 702 can move inside the circular tubes 701.

[0026] Moreover, two tension springs 705 are fixedly connected between the two moving plates 702. When the two moving plates 702 approach each other, they will squeeze the two tension springs 705.

[0027] Limiting rods 703 are fixedly connected to the sides of the two moving plates 702 away from each other. When the two moving plates 702 move, they will drive the two limiting rods 703 to move. A plurality of limiting grooves 704 are opened on both sides inside the fixed frame 3, and the limiting rods 703 are inserted into the limiting grooves 704. When the limiting rods 703 are inserted into the limiting grooves 704, the movable support rod 4 can be prevented from continuing to rotate. The plurality of limiting grooves 704 are annularly distributed inside the fixed frame 3.

[0028] Two sliding grooves 706 are opened on the inner walls of the two circular tubes 701. The two moving plates 702 are both located in the two sliding grooves 706, and the two moving plates 702 are both slidably connected to the two sliding grooves 706. The two moving plates 702 can move along the two sliding grooves 706.

[0029] A threaded component 10 is provided between the fixed plate 8 and the connecting column 2. Universal self-locking wheels 9 are provided at the bottoms of the two fixed plates 8. Through the universal self-locking wheels 9, it is convenient for the user to push the telescopic guardrail 1 to move, so as to adjust the position of the telescopic guardrail 1. Lighting lamps 11 are fixedly installed on the top surfaces of the two connecting columns 2, and a battery for powering the lighting lamps 11 is provided inside the connecting column 2. The lighting lamps 11 can emit light to illuminate the staff working at night.

[0030] The threaded component 10 includes a threaded rod 1001 threadedly connected to the fixed plate 8. Two threaded grooves 1002 are opened at one ends of the two connecting columns 2 away from each other. The two threaded grooves 1002 are arranged longitudinally, and the threaded rod 1001 is threadedly connected to the threaded grooves 1002.

[0031] The working principle of the utility model is as follows: First, with the assistance of the universal self-locking wheel 9, the telescopic guardrail 1 is driven to move to the construction area, and the telescopic guardrail 1 is pulled to extend outward for isolation and protection. Then, the threaded rod 1001 in the threaded component 10 is rotated to move outward, releasing its locking fixation with the lower threaded groove 1002. At the same time, the fixing plate 8 and the universal self-locking are lifted upward until the threaded rod 1001 is locked and fixed with the upper threaded groove 1002, making the telescopic guardrail 1 contact the ground, expanding its contact area with the ground, reducing the remaining gap, and preventing small animals nearby from entering the construction area through the gap between the telescopic guardrail 1 and the ground, thus avoiding interference with the building construction and enhancing the use effect. Then, the two pairs of movable support rods 4 and the support base plate 6 are toggled to flip downward until the support base plate 6 contacts the ground, squeezing the two pairs of limit rods 703 in the rotation limit mechanism to move toward each other inside the round tube 701, and driving the two pairs of tension springs 705 to be compressed. Until the support base plate 6 flips to contact the ground, the two pairs of movable support rods 4 stop moving. At this time, the two pairs of limit rods 703 also move away from each other under the elastic action of the two pairs of tension springs 705 and extend into the corresponding limit grooves 704 respectively to limit and fix the movable support rods 4, prompting the support base plate 6 to maintain stable contact with the ground, realizing stable support for the telescopic guardrail 1, making the telescopic guardrail 1 not easily fall over when affected by wind or accidental human touch, reducing damage, and ensuring its normal use. Moreover, the lighting lamp 11 can provide lighting effects at night, facilitating the construction of night workers.

[0032] Although the present utility model has been described in detail with general descriptions and specific embodiments above, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
