DETAILED DESCRIPTION

[0027] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention:

[0028] The utility model provides Figures 1 to 8 A construction guardrail for a construction project shown in the figure includes a first support column 1, and a movable column 2 and a second support column 3 are sequentially arranged on the right side of the first support column 1, wherein the second support column 3 and the first support column 1 have the same structure; a telescopic mechanism is arranged between the first support column 1 and the movable column 2, and between the movable column 2 and the second support column 3. When in use, the movable column 2 and the second support column 3 can be driven to move toward the first support column 1 by controlling the telescopic mechanism to adjust the length of the guardrail, providing convenience for use and storage. In addition, in this embodiment, a limiting mechanism 6 is arranged at the bottom of the first support column 1 and the second support column 3 to ensure the stability of the first support column 1 and the second support column 3 after installation.

[0029] When in use, the first support column 1 is fixed in position by a limiting mechanism 6 arranged at its bottom, and the opening and closing of the two telescopic mechanisms are gradually controlled according to the conditions of the construction site. After the state adjustment of the telescopic mechanism is completed, the second support column 3 can be fixed and installed by using the limiting mechanism 6. The whole operation is simple and fast, and no assembly or disassembly is required, which improves the convenience of operation, saves time and effort, and ensures construction efficiency. After use, the first support column 1, the movable column 2 and the second support column 3 are retracted by retracting the telescopic mechanism, so that the first support column 1, the movable column 2 and the second support column 3 can form a rectangular parallelepiped structure, which is convenient for subsequent storage and transportation.

[0030] Furthermore, the first support column 1 and the second support column 3 each include two symmetrically arranged first support plates 102, and the two first support plates 102 are spaced apart so as to accommodate the telescopic mechanism and reduce the occupation of the external space; the first rotating shaft 101 is disposed on both upper and lower sides between the two first support plates 102, and a bottom plate 103 is disposed at the bottom end of the two first support plates 102. The limiting mechanism 6 is disposed on the bottom plate 103.

[0031] Further, the telescopic mechanism includes a first link mechanism 4 arranged between the first support column 1 and the movable column 2, and a second link mechanism 5 arranged between the movable column 2 and the second support column 3, wherein the first link mechanism 4 and the second link mechanism 5 have the same structure, which can not only realize rapid installation and use, improve work efficiency, but also improve the commonality of parts and components, and reduce the cost of overhaul and maintenance. The first link mechanism 4 and the second link mechanism 5 both include a first movable rod 401 and a second movable rod 402, one end of the first movable rod 401 and the second movable rod 402 are both connected to the first rotating shaft 101, and the other end of the first movable rod 401 is connected to the third movable rod 403; the other end of the second movable rod 402 is connected to the fourth movable rod 404, and a second connecting rod 406 is arranged between one end of the first movable rod 401 and the connecting end of the second movable rod 402 and the fourth movable rod 404; a first connecting rod 405 is arranged between the connecting end of the first movable rod 401 and the third movable rod 403 and the fourth movable rod 404, and the other end of the first connecting rod 405 is arranged with a third connecting plate 407.

[0032] When in use, directly pull the movable column 2 or the second support column 3, the first movable rod 401 and the second movable rod 402 rotate on the first rotating shaft 101, the first movable rod 401 and the third movable rod 403 rotate along the connection point, and the angle between the first movable rod 401 and the third movable rod 403 will change. When the angle between the first movable rod 401 and the third movable rod 403 is smaller, the distance between the first movable rod 401 and the third movable rod 403 is closer, and the telescopic mechanism is in a retracted state; when the angle between the first movable rod 401 and the third movable rod 403 is larger, the distance between the first movable rod 401 and the third movable rod 403 is farther, and the telescopic mechanism is in an extended state, with a simple structure and easy and quick operation. Since the activity state of the second movable rod 402 and the fourth movable rod 404 is consistent with the activity state of the first movable rod 401 and the third movable rod 403, the activity state of the second movable rod 402 and the fourth movable rod 404 can refer to the activity state of the first movable rod 401 and the third movable rod 403.

[0033] In addition, in this embodiment, the stability of the first movable rod 401 and the third movable rod 403 can be enhanced by setting the first connecting rod 405, thereby avoiding shaking or falling off during the extension and retraction process; during the extension and retraction process, the third connecting plate 407 of the first connecting rod 405 drives the second connecting shaft 204 to slide up and down inside the sliding groove 201, and moves around the second connecting shaft 204, which can indirectly increase the stability of the telescopic mechanism.

[0034] Furthermore, the movable column 2 includes two second support plates 205, and second rotating shafts 206 are arranged on the upper and lower sides between the two second support plates 205. The end faces of the two second support plates 205 are provided with penetrating sliding grooves 201, and the side walls of the sliding grooves 201 are provided with card grooves 202. The interior of the sliding grooves 201 is slidably connected with card blocks 203, and a second connecting shaft 204 is arranged between the two card blocks 203; sliders are arranged on both sides of the card blocks 203, and the sliders are connected to the card grooves 202.

[0035] When in use, the two second support plates 205 are connected by the upper and lower second rotating shafts 206 and the pushing plate 7 at the bottom to form a whole. The second rotating shaft 206 is connected to the third movable rod 403, and the third connecting plate 407 is connected to the second connecting shaft 204 to limit the position and connect the telescopic mechanism. The second connecting shaft 204 is driven to slide by the third connecting plate 407, and the block 203 of the second connecting shaft 204 slides inside the sliding groove 201. The block 203 is connected to the slot 202 through a slider to prevent the block 203 from detaching from the sliding groove 201 during sliding. The third connecting plate 407 surrounds the second connecting shaft 204 and drives the second connecting shaft 204 to slide, thereby facilitating the extension and retraction of the telescopic mechanism.

[0036] The bottom ends of the two second support plates 205 are provided with a push plate 7, and the bottom ends of the push plate 7 are provided with a plurality of through grooves 701. When in use, as the telescopic mechanism extends, it will push the movable column 2 to move, and the push plate 7 at the bottom end of the movable column 2 will level the potholes on the moving route; specifically, the push plate 7 is an inverted trapezoid, and the edge of the push plate 7 is inclined to clean the soil on the potholes, and the through grooves 701 on the bottom surface of the push plate 7 comb the soil, pushing the soil at the high place to the low-lying road surface, and the soil is combed to the low-lying place through the through grooves 701, so that the road surface of the moving route is leveled and the height of the guardrail is consistent.

[0037] Furthermore, the limiting mechanism 6 includes a fixed column 602 located at the bottom end of the bottom plate 103 and a connecting column 601 located at the top end of the bottom plate 103. A connecting hole 603 is provided at the top end of the fixed column 602. A through hole for the connecting column 601 to pass through is provided at a position on the bottom plate 103 opposite to the connecting hole 603. The connecting column 601 passes through the bottom plate 103 through the through hole and is arranged inside the fixed column 602. A through hole 604 is provided on the side wall of the fixed column 602. A groove is provided at the lower side of the outer circumferential surface of the connecting column 601. A connecting shaft 605 is provided at the top end of the inner part of the groove. A card plate 606 is provided inside the groove. The card plate 606 is rotatably connected and arranged inside the groove through the connecting shaft 605. A stretching mechanism is provided between the inner part of the groove and the card plate 606 to control the reset of the card plate 606. The stretching mechanism can be a spring. The clamping plate 606 is clamped with the through hole 604 , and after the connecting column 601 is connected with the fixing column 602 , the clamping plate 606 can extend out from the through hole 604 .

[0038] When in use, after the guardrail is placed at the designated position, the fixing column 602 is embedded in the ground, and the connecting column 601 moves toward the inside of the fixing column 602. During the movement, the card plate 606 is squeezed by the inner side wall of the fixing column 602, and the card plate 606 squeezes the stretching mechanism to contract, so that the card plate 606 fits with the inside of the groove, making it easier for the connecting column 601 to enter the inside of the fixing column 602. Then, as the card plate 606 moves to the position corresponding to the through hole 604, the stretching mechanism pops out the card plate 606 under the restoring force. At this time, the card plate 606 pops out from the through hole 604 of the fixing column 602 and is inserted into the soil in an eight-shaped shape along with the fixing column, so that the limiting mechanism 6 is firmly fixed in the soil, avoiding the guardrail from tilting or overturning during use, which affects the use of the guardrail. After the fixing column 602 enters the soil, the soil will enter the through hole 604 , and the elastic force of the stretching mechanism is greater than the squeezing force of the soil on the clamping plate 606 , ensuring that the clamping plate 606 smoothly passes through the through hole 604 and enters the soil.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
