[0001] This utility model relates to the field of building safety railing technology, specifically a building safety railing with a tension structure. Background Technology

[0002] Construction safety railings are made of iron pipes, processed through seamless pipe bending, welding, grinding and polishing, high-pressure baking paint, and film application. They are widely used as isolation and warning structures in construction sites. Tension structures are required during the use of construction safety railings to improve their effectiveness. For example:

[0003] Chinese Patent Publication No. CN213144106U discloses a forestry protective fence, belonging to the technical field of forestry protective fences. It includes a protective frame, a fixed rod on one side of the frame, a protective rod inside the frame, a fixed rod chuck at the bottom of the fixed rod, and a digging cone at the bottom of the fixed rod. This invention utilizes two rotatable, nested sleeves outside the fixed rod. One side of the sleeve is fixedly connected to a protective fence buckle, and the other side is fixedly connected to a protective fence slot. The buckle and slot fit together. During installation, the buckle of one fence panel is inserted into the slot of the other; during disassembly, the buckle is pulled out from the slot of the other. This makes installation and disassembly more convenient, solving the problem of cumbersome installation and disassembly methods in existing forestry protective fences.

[0004] The existing technical solutions described above have the following drawbacks: when connecting guardrails, they are connected by buckles and slots, the tensile effect of ordinary building safety guardrails is not good, and the replacement of the tensile structure is not convenient. Therefore, this utility model provides a building safety guardrail with a tensile structure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a building safety railing with a tension structure to solve the problems mentioned in the background art, such as the poor tension effect of ordinary building safety railings when connecting guardrails by means of buckles and slots, and the inconvenience of replacing the tension structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a building safety railing with a tension structure, comprising a railing rod, a fixing plate installed at the left end of the railing rod, and an installation block connected to the right side of the railing rod. A connecting structure is installed on the outer side of the installation block and the outer side of the fixing plate, and the connecting structure includes a connecting block, an installation rod and a fixing block.

[0007] A limiting block is installed on the inner outer side of the guardrail, and a movable block is connected to the outer side of the limiting block, and a connecting rod is installed on the middle side of the movable block. A mounting plate is connected to the inner side of the limiting block.

[0008] The first movable rod is installed on the upper inner side of the mounting plate, and a fixed rod is connected to the front side of the first movable rod. A second movable rod is rotatably installed in the middle of the first movable rod, and a connecting rod is installed on the outer side of the second movable rod and the outer side of the first movable rod. A connecting plate is installed on the rear side of the connecting rod, and a protective net is fixedly connected to the outer side of the connecting plate.

[0009] Preferably, the first movable rod and the second movable rod are connected by rotation, and the first movable rod is connected to the mounting plate by sliding.

[0010] Preferably, the first movable rod and the fixed rod are connected by a thread, and the front side of the first movable rod has a groove-like structure.

[0011] Preferably, connecting blocks are installed on the outer side of the mounting block and the outer side of the fixing plate, and a fixing block is fixedly connected to the outer side of the connecting block, and a mounting rod is connected to the right side of the fixing block.

[0012] Preferably, the limiting block and the mounting plate are connected by a snap-fit ​​mechanism, and the vertical cross-sectional shape of the limiting block is an "L" shape.

[0013] Preferably, the limiting block and the movable block are connected by rotation, and the limiting blocks are symmetrically distributed about the center line of the mounting plate.

[0014] Preferably, the connecting block and the mounting block are connected by a snap-fit ​​mechanism, and the connecting blocks are symmetrically distributed about the center line of the fixing block.

[0015] Preferably, the mounting rod and the connecting block are connected by threads and serve to fix the guardrails together.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the building safety railing with the tension structure facilitates the connection between guardrails, facilitates the tensioning of the building safety railing, and facilitates the replacement of the tension structure;

[0017] By placing the guardrail on the outside of another, bringing the mounting block and the fixing plate close together, and then placing the fixing block on the outside of the fixing plate, the fixing block drives the connecting block to engage with the outside of the mounting block and the outside of the fixing plate respectively. By rotating the mounting rod, the mounting rod is threaded on the right side of the fixing block, thereby threading the mounting rod on the middle side of the connecting block, and then threading the mounting rod on the outside of the fixing plate, which facilitates the connection between the guardrails.

[0018] By rotating the fixed rod, it is threaded onto the front side of the mounting plate, thus separating the fixed rod from the front side of the first movable rod. Then, the guardrail is pulled, causing the guardrail to move the mounting plate, which in turn causes the second movable rod, which is rotatably connected to the mounting plate, to rotate. This causes the first movable rod, which is rotatably connected to the second movable rod, to slide on the upper side inside the mounting plate. This causes the connecting rod, which is rotatably connected to both the first and second movable rods, to slide inside the connecting plate, thereby causing the connecting plate to extend the protective netting. This changes the distance between the guardrails, making it easier to stretch the guardrails.

[0019] By rotating the connecting rod, the connecting rod is threaded onto the inside of the movable block, thereby separating the connecting rod from the outside of the guardrail. Then, by pulling down the limiting block, the limiting block is separated from the outside of the mounting plate, thereby separating the mounting plate from the inside of the guardrail, making it convenient to replace the mounting plate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a building safety railing with a tension structure, including a fixing plate 10 installed on the left end of the railing 1, and an installation block 7 connected to the right side of the railing 1. A connecting structure is installed on the outer side of the installation block 7 and the outer side of the fixing plate 10. The connecting structure includes a connecting block 11, an installation rod 12 and a fixing block 13. The railing 1 is placed on the outer side of the other railing, so that the installation block 7 and the fixing plate 10 are close to each other. Then the connecting structure is placed on the outer side of the fixing plate 10, so that the connecting structure is connected on the outer side of the fixing plate 10, which facilitates the connection between the railing 1 rails.

[0029] The limiting block 9 is installed on the inner outer side of the guardrail 1, and the outer side of the limiting block 9 is connected to the movable block 14. The middle side of the movable block 14 is equipped with a connecting rod 15, and the inner side of the limiting block 9 is connected to the mounting plate 2. Rotating the connecting rod 15 connects the connecting rod 15 to the inner side of the movable block 14, thereby separating the connecting rod 15 from the outer side of the guardrail 1. Then, pulling the limiting block 9 down separates the limiting block 9 from the outer side of the mounting plate 2, thereby separating the mounting plate 2 from the inner side of the guardrail 1. Then, through the connection between the movable block 14 and the limiting block 9, the movable block 14 is rotated to the outer side of the movable block 14. Rotating the connecting rod 15 connects the connecting rod 15 to the inner side of the movable block 14, thereby connecting the connecting rod 15 to the outer side of the guardrail 1, which facilitates the replacement of the mounting plate 2.

[0030] The first movable rod 3 is installed on the upper inner side of the mounting plate 2, and a fixed rod 8 is connected to the front side of the first movable rod 3. A second movable rod 4 is rotatably installed in the middle of the first movable rod 3, and a connecting rod 16 is installed on the outer side of the second movable rod 4 and the outer side of the first movable rod 3. A connecting plate 5 is installed on the rear side of the connecting rod 16, and a protective net 6 is fixedly connected to the outer side of the connecting plate 5. Rotating the fixed rod 8 connects it to the front side of the mounting plate 2, thereby separating the fixed rod 8 from the front side of the first movable rod 3. Pulling the guardrail 1 causes the guardrail 1 to move the mounting plate 2, thereby rotating the second movable rod 4 connected to the mounting plate 2. This causes the first movable rod 3 connected to the second movable rod 4 to slide on the upper inner side of the mounting plate 2, and the connecting rod 16, which is connected to both the first movable rod 3 and the second movable rod 4, to slide inside the connecting plate 5. This causes the connecting plate 5 to extend the protective net 6, thereby changing the distance between the guardrail 1s, making it easier to stretch the guardrail 1s.

[0031] When using construction safety railings with tension structures, specifically as follows: Figure 1 , Figure 2 and Figure 5 In this arrangement, guardrail 1 is placed on the outside of another guardrail, so that mounting block 7 and fixing plate 10 are close to each other. Connecting block 11 is connected to mounting block 7 by a snap-fit ​​method, and connecting block 11 is symmetrically distributed about the center line of fixing block 13. Then, fixing block 13 is placed on the outside of fixing plate 10, so that fixing block 13 drives connecting block 11 to snap-fit ​​on the outside of mounting block 7 and fixing plate 10 respectively. Mounting rod 12 is connected to connecting block 11 by a thread and plays a fixing role between guardrail 1. Rotating mounting rod 12 makes mounting rod 12 threaded on the right side of fixing block 13, so that mounting rod 12 is threaded on the middle side of connecting block 11, and then threaded on the outside of fixing plate 10, which facilitates the connection between guardrail 1.

[0032] Specific examples Figure 1 , Figure 3 , Figure 4 and Figure 6In the process of rotating the fixed rod 8, the first movable rod 3 is connected to the fixed rod 8 by a thread, and the front side of the first movable rod 3 has a groove structure, so that the fixed rod 8 is threaded to the front side of the mounting plate 2, thereby separating the fixed rod 8 from the front side of the first movable rod 3. Then, the guardrail 1 is pulled, so that the guardrail 1 drives the mounting plate 2 to move, thereby causing the second movable rod 4, which is rotatably connected to the mounting plate 2, to rotate. This causes the first movable rod 3, which is rotatably connected to the second movable rod 4, to slide inside the upper side of the mounting plate 2. The first movable rod 3 and the second movable rod 4 are rotatably connected, and the first movable rod 3 is slidably connected to the mounting plate 2, so that the connecting rod 16, which is rotatably connected to both the first movable rod 3 and the second movable rod 4, slides inside the connecting plate 5, thereby causing the connecting plate 5 to drive the protective net 6 to extend, thereby changing the distance between the guardrail 1, which facilitates the stretching of the guardrail 1.

[0033] Specific examples Figure 1 and Figure 2 In the process, rotating the connecting rod 15 causes it to be threaded onto the inside of the movable block 14, thus separating the connecting rod 15 from the outside of the guardrail 1. The limiting block 9 and the mounting plate 2 are connected by a snap-fit ​​mechanism, and the vertical cross-section of the limiting block 9 is an "L" shape. Pulling the limiting block 9 downwards causes it to separate from the outside of the mounting plate 2, thus separating the mounting plate 2 from the inside of the guardrail 1. The limiting block 9 and the movable block 14 are connected by a rotation mechanism, and the limiting blocks 9 are symmetrically distributed about the center line of the mounting plate 2. Through the rotational connection between the movable block 14 and the limiting block 9, the movable block 14 is rotated to the outside of the movable block 14. Rotating the connecting rod 15 causes it to be threaded onto the inside of the movable block 14, thus connecting the connecting rod 15 to the outside of the guardrail 1, facilitating the replacement of the mounting plate 2.
