Description

Technical Field

[0001] This utility model relates to the field of protective frame technology, specifically to a protective frame with docking and limiting capabilities. Background Technology

[0002] Road and bridge engineering is a general term for road and bridge engineering, and is a core branch of civil engineering. It mainly solves the problems of planning, design, construction and maintenance of transportation infrastructure. Protective frames are used in the construction process of road and bridge engineering to prevent pedestrians and vehicles from entering dangerous areas during road and bridge construction or operation, and to prevent accidents such as falls and collisions. Through modular design, multiple sections of protective frames can be quickly connected to form a continuous protective wall, which solves the problems of limited length and difficult splicing of traditional protective frames. The protection range can be dynamically adjusted according to the length of the construction site, reducing the cost of repeated construction.

[0003] Chinese utility model patent CN221703379U discloses a protective frame, including a compression assembly comprising two sets of push-button plates. The outer wall of the push-button plate is fixedly connected to the inner wall of a fixed column. A sliding shaft is slidably connected through the inner wall of the push-button plate. One end of a spring is fixedly connected to the inner outer wall of the left end of the push-button plate, and the other end of the spring is fixedly connected to the inner outer wall of the right end of the push-button plate. The limiting assembly includes a sliding hook, the outer wall of which is slidably connected to the inner wall of a rotating plate. The outer end of the hook is slidably connected to a positioning shaft, and the outer wall of the positioning shaft is fixedly connected to the inner wall of the outer end of the rotating plate. The outer wall of the sliding hook is elastically connected to the inner wall of the outer end of the rotating plate through a return spring. However, the bottom stability of the protective frame is poor. As warning signs need to be hung during construction, the center of gravity becomes increasingly unstable as the height of the device increases. It is easily tilted by road vibrations and wind pressure from passing vehicles. Furthermore, the device itself is not functional enough, as the protective device needs to be used alternately during the day and night, and its height needs to be constantly changed depending on the usage scenario. Utility Model Content

[0004] The purpose of this invention is to provide a protective frame that can be docked and limited, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective frame with docking and limiting capabilities, comprising a stabilizing component, a first protective frame plate on the top of the stabilizing component, first main folding limiting components on the left and right sides of the rear end of the first protective frame plate, a secondary folding limiting component fixedly installed on the top of the first main folding limiting component, a second protective frame plate on the front end of the secondary folding limiting component, a reflector movably installed at the rear end of the second protective frame plate, and two hanging rods fixedly installed at the front end of the second protective frame plate;

[0006] The stabilizing component includes a base with several through holes on its surface. Several self-tapping rivets are threaded onto the inner walls of the through holes. A rectangular groove is formed on the top of the base. One end of a spring is fixedly installed on both sides of the inner wall of the rectangular groove, and a sliding block is fixedly connected to the other end of the spring.

[0007] The main folding limiting assembly includes a folding rod with sliding grooves on both sides. The inner wall of the folding rod is provided with an L-shaped plate, and a return spring is fixedly installed on the side of the L-shaped plate. The inner wall of the folding rod is provided with a movable block. A short rod is slidably connected to the inner wall of the sliding groove. The short rod is fixedly installed at both ends of the connecting rod. The other end of the connecting rod is rotatably connected to the folding short rod through the short rod.

[0008] The beneficial effects of this utility model are as follows: the height of the entire protective frame can be quickly changed by operating the folding short rod and connecting rod to adapt to different needs. It occupies little space after folding, making it easy to transport. With the help of the movable block and spring, the second protective frame plate is locked in a vertical state, providing stable support. When it is necessary to lower the protective frame, the movable block must be manually moved first to prevent the protective frame from accidentally folding or falling when subjected to external force, thus improving operational safety. During the day, after raising the protective frame, a conspicuous warning sign can be hung on the hanging rod. At night, the protective frame can be lowered so that vehicles can see the reflector on the protective frame, ensuring that it can play a warning role under all weather conditions. The base is fixed to the ground by self-tapping rivets to ensure the overall stability.

[0009] To ensure that when a vehicle passes and generates wind pressure, the entire protective plate can move backward, with springs absorbing the impact energy, and automatically return to its original position after the vehicle has moved away:

[0010] As a further improvement to the above technical solution: the sliding block is fixedly installed at the bottom of the first protective frame plate, and stabilizing components are respectively provided on the left and right sides of the first protective frame plate.

[0011] The beneficial effects of this improvement are as follows: With the above settings, sliding blocks are fixedly installed on both sides of the bottom of the first protective plate. As the sliding blocks move back and forth in the rectangular groove, the spring is subjected to force, contracts and rebounds, driving the first protective plate to move.

[0012] To prevent the protective frame panels from accidentally folding or falling:

[0013] As a further improvement to the above technical solution: the inner wall of the folding rod is provided with a fixed rod, the movable block is rotatably connected to the inner wall of the folding rod through the fixed rod, one end of the connecting rod is slidably connected to the inner wall of the sliding groove through a short rod, the other end of the connecting rod is rotatably connected to the surface of the folding short rod through the short rod, one end of the folding rod is rotatably connected to a rotating rod, and the folding rod is rotatably connected to the inner wall of the folding short rod through the rotating rod.

[0014] The beneficial effects of this improvement are as follows: by raising the secondary folding limiting assembly, during the raising process, the short rod of the connecting rod in the secondary folding limiting assembly reaches the bottom of the sliding groove, and the folding rod is in a vertical state. When it is necessary to lower the protective frame plate, the movable block must be manually moved first to make it horizontally compress the spring, so that the short rod of the connecting rod passes through and slides back to the bottom, so that the second protective frame plate is locked in a vertical state, providing stable support and preventing accidental descent.

[0015] To allow for rapid adjustment of the entire protective frame's height to adapt to different needs:

[0016] As a further improvement to the above technical solution: the first main folding limiting component and the secondary folding limiting component have the same composition structure.

[0017] The beneficial effects of this improvement are as follows: By setting up the above, the folding short rods at the rear ends of the first main folding limit assembly and the secondary folding limit assembly are raised or lowered, so that the folding short rods rotate on the surface of the folding rods via the rotating rods, causing one end of the connecting rod to slide in the sliding groove through the short rods, so that the folding rods extend out or fold into the inner wall of the folding short rods. This can be achieved manually without the need for additional complex tools or power sources, and is easy to implement on the construction site.

[0018] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0026] Please see Figures 1 to 5 The protective frame that can be docked and limited includes a stabilizing component 1. The top of the stabilizing component 1 is provided with a first protective frame plate 2. The left and right sides of the rear end of the first protective frame plate 2 are respectively provided with first main folding limiting components 3. The top of the first main folding limiting component 3 is fixedly installed with a secondary folding limiting component 4. The front end of the secondary folding limiting component 4 is provided with a second protective frame plate 5. The rear end of the second protective frame plate 5 is movably installed with a reflector 6. The front end of the second protective frame plate 5 is fixedly installed with two hanging rods 7.

[0027] The stabilizing component 1 includes a base 101. The surface of the base 101 has several through holes. The inner walls of the several through holes are threaded with several self-tapping rivets 102. The top of the base 101 has a rectangular groove 103. One end of a spring 104 is fixedly installed on both sides of the inner wall of the rectangular groove 103. The other end of the spring 104 is fixedly connected to a sliding block 105.

[0028] The main folding limiting assembly 3 includes a folding rod 301, with sliding grooves 302 on both sides of the folding rod 301. An L-shaped plate 303 is provided on the inner wall of the folding rod 301, and a return spring 304 is fixedly installed on the side of the L-shaped plate 303. A movable block 305 is provided on the inner wall of the folding rod 301. A short rod is slidably connected to the inner wall of the sliding groove 302. The short rod is fixedly installed at both ends of the connecting rod 306. The other end of the connecting rod 306 is rotatably connected to a folding short rod 307 through the short rod.

[0029] In this embodiment, as Figure 3 As shown, the sliding block 105 is fixedly installed at the bottom of the first protective frame plate 2, and stabilizing components 1 are respectively provided on the left and right sides of the first protective frame plate 2.

[0030] In this embodiment, as Figure 4 As shown, the inner wall of the folding rod 301 is provided with a fixed rod, and the movable block 305 is rotatably connected to the inner wall of the folding rod 301 through the fixed rod. One end of the connecting rod 306 is slidably connected to the inner wall of the sliding groove 302 through a short rod, and the other end of the connecting rod 306 is rotatably connected to the surface of the folding short rod 307 through a short rod. One end of the folding rod 301 is rotatably connected to a rotating rod, and the folding rod 301 is rotatably connected to the inner wall of the folding short rod 307 through the rotating rod.

[0031] In this embodiment, as Figure 2 As shown, the first main folding limiting component 3 and the secondary folding limiting component 4 have the same composition structure.

[0032] The working process of this dockable and limit-positioning protective frame is as follows:

[0033] First, place the protective frame in the required position. Secure the base 101 to the ground by rotating the self-tapping rivets 102. During daytime use, raise the protective frame by manually lifting the folding short rod 307. The folding short rod 307 rotates on the surface of the folding rod 301 via a rotating rod. Simultaneously, one end of the connecting rod 306 rotates on the surface of the folding short rod 307 via the short rod, and the other end of the connecting rod 306 slides on the inner wall of the sliding groove 302 via the short rod. When the short rod contacts the movable block 305, it passes over the surface of the movable block 305, and the return spring 304 at its bottom is compressed, causing the movable block 305 to rotate to a horizontal position via the fixed rod, allowing the short rod to pass through. As the short rod slides... When the sliding groove 302 reaches its top, the folding short rod 307 is in a horizontal state, and the second protective frame plate 5 is in a horizontal state. At this time, the secondary folding limit component 4 at the rear end of the second protective frame plate 5 is also raised to make the second protective frame plate 5 vertical, so that the entire protective frame is raised. At this time, a warning sign is hung on the hanging rod 7 to remind passing vehicles to pay attention to safety. When passing vehicles pass through the protective frame and generate wind pressure, the sliding block 105 at the bottom of the first protective frame plate 2 moves on the inner wall of the rectangular groove 103. At this time, the spring 104 is squeezed and contracted, driving the entire protective plate to move backward. When the vehicle moves away, the spring 104 rebounds, driving the protective plate to return to its original position, avoiding damage to the protective plate itself caused by mutual forces.

[0034] When used at night, the second protective frame plate 5 needs to be lowered. The movable block 305 is manually moved so that the return spring 304 at its bottom is squeezed until the movable block 305 is in a horizontal state. The folding short rod 307 is pressed down, and the folding short rod 307 rotates on the surface of the folding rod 301 through the rotating rod. At the same time, one end of the connecting rod 306 rotates on the surface of the folding short rod 307 through the short rod, and the other end of the connecting rod 306 slides on the inner wall of the sliding groove 302 through the short rod. When the short rod slides past the top of the L-shaped plate 303 and the surface of the movable block 305 to the bottom of the sliding groove 302, the connecting rod 306 drives the folding short rod 307 to retract to the surface of the folding rod 301 through the short rod, so that the second protective frame plate 5 is in a horizontal state. At this time, the secondary folding limit component 4 at the rear end of the second protective frame plate 5 is also retracted downward to make the second protective frame plate 5 vertical. When the second protective frame plate 5 is folded and retracted to the rear end of the first protective frame plate 2, the reflector 6 can be seen when the vehicle is driving at night through the front of the protective frame, which can help remind oncoming vehicles to pay attention to safety.
