Description

Technical Field

[0001] This utility model belongs to the field of building safety fence technology, and specifically relates to a building safety fence for emergency management. Background Technology

[0002] Construction safety fences are important safety facilities widely used in construction sites. They are mainly set up at the edge of the construction site, around dangerous areas, and in specific areas where construction is underway. Their function is to clearly delineate the construction area from the non-construction area, preventing unauthorized personnel from accidentally entering the construction site and facing dangers such as falls or being struck by objects. At the same time, safety fences can also play a certain role in protecting the equipment and materials on the construction site, preventing them from being damaged or stolen by external factors.

[0003] Currently, existing safety fences for construction project management typically use screws to assemble and fix various components, resulting in slow installation speed and reduced work efficiency. Chinese Patent No. CN217812799U discloses a safety fence for construction project management that includes two hollow columns. A limit gear is sleeved through the upper end of a roller through the hollow columns. A second handwheel is fixedly connected to the upper end of the roller. A fixing block is fixedly installed on the upper surface of the hollow columns, and a hand-adjusting bolt is screwed into the inside of the fixing block. One end of the hand-adjusting bolt is rotatably connected to a limit block that engages with the limit gear. This invention provides a safety fence for construction project management that, by rotating the hand-adjusting bolt, disengages the limit block rotatably connected to it from the tooth gap of the limit gear, allowing the roller to rotate freely and facilitating the unfolding of the protective net from the outside of the roller. This solves the technical problem of existing safety fences for construction project management, which typically use screws to assemble and fix various components, resulting in slow installation speed and reduced work efficiency.

[0004] While the aforementioned device can be deployed and used quickly and conveniently during practical application, it has certain shortcomings. The protective netting is fixedly installed on a roller, making it highly susceptible to damage in outdoor environments due to various complex environmental factors. For example, it may be damaged by strong winds, scratches from foreign objects, or other unexpected impacts. Furthermore, the fixed installation method makes it inconvenient to quickly disassemble and replace the netting when it is damaged. This means that any problems with the netting not only affect the device's normal function but may also pose safety hazards to the user. Therefore, the device has certain deficiencies and urgently needs improvement to enhance its practicality and reliability. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a building safety fence for emergency management, so as to solve the problem that the protective netting of existing safety fences is not easy to be quickly disassembled and repaired when damaged.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An emergency management building safety fence includes two base blocks. A concave seat is fixedly installed on the top of the base blocks. A snap-fit ​​mechanism is fixedly installed on the top and bottom of the inner side of the concave seat. A winding roller is installed on the inner side of the concave seat through the snap-fit ​​mechanism. A protective net is wound on the outer surface of the winding roller. The protective nets on the two winding rollers are connected to each other.

[0008] The locking mechanism includes a guide rail, which is rotatably connected to the top and bottom of the guide rail. A slider is slidably connected inside the guide rail. A locking component is fixedly installed on one side of the guide rail. The end of the locking component locks into the slider. The inner side of the slider is fixedly connected to both ends of the winding roller.

[0009] As a preferred technical solution, the snap-fit ​​assembly includes snap-fit ​​holes and side frames. The side frames are fixedly installed on the outer side of the guide rail. Torsion springs are fixedly connected to both sides of the inner side frames. Rotary shafts are rotatably connected to both sides of the side frames. The inner end of the rotating shaft is fixedly connected to the outer end of the torsion spring. A fixed plate is fixedly connected to the outer end of the rotating shaft. A limit rod is fixedly installed at the bottom of the fixed plate. The snap-fit ​​holes are opened at both ends of the bottom of the slider. The end of the limit rod is inserted into the inner side of the snap-fit ​​hole.

[0010] As a preferred technical solution, the overall side shape of the card hole is arc-shaped, the outer end of the limiting rod is also arc-shaped, the arc-shaped part of the outer end of the limiting rod and the torsion spring are concentrically arranged, and the card hole is also concentrically arranged with the torsion spring.

[0011] As a preferred technical solution, a handrail frame is fixedly connected to the outer side of the fixed plate, and an anti-slip handrail glove is fixedly connected to the outer surface of the handrail frame. The overall cross-sectional shape of the inner side of the guide rail and the slider is set to a convex shape.

[0012] As a preferred technical solution, a protective cover is hinged to one side of the concave seat. The overall cross-sectional shape of the protective cover is U-shaped. A reserved groove is provided on the side of the protective cover away from the hinge with the concave seat. The protective net passes through the reserved groove and is wrapped around the outer surface of the take-up roller.

[0013] As a preferred technical solution, both the upper and lower ends of the outer side of the protective cover are threaded with hand-tightening screws, and the end of the hand-tightening screws passes through the protective cover and is threadedly connected to the concave seat.

[0014] As a preferred technical solution, a mounting plate is fixedly installed at the bottom of the base block, and mounting holes are provided at the four corners of the mounting plate, and the mounting holes are countersunk holes.

[0015] In summary, the present invention has the following main advantages:

[0016] First, this device is equipped with a snap-fit ​​mechanism. When in use, the protective net on the take-up roller inside the concave seat can be unfolded to form a safety fence. The protective net is flexible in form, can adapt to irregular construction sites, and is convenient for site maintenance. The protective cover protects the protective net during transportation. During inspection and maintenance, the protective cover can be opened by turning the hand screw, which facilitates the disassembly and assembly of the take-up roller and provides convenience for the replacement and maintenance of the protective net. This design improves the practicality and convenience of the device during use, effectively meets the needs of construction sites for safety fences, ensures construction safety, and also facilitates daily maintenance operations.

[0017] Secondly, this device uses a snap-fit ​​mechanism. Adjusting the handrail causes the fixed plate to rotate, disengaging the rotating shaft and the limiting rod from the snap-fit ​​hole. The slider loses its limit, and the torsion spring contracts, allowing the slider to be pulled out for quick disassembly and assembly of the winding roller and safety net. After maintenance, the slider is inserted into the guide rail, the handrail is released, and the torsion spring returns to its original position. The fixed plate then drives the limiting rod to precisely insert into the snap-fit ​​hole. The limiting rod and the snap-fit ​​hole mutually limit and engage, enabling quick replacement and disassembly of the winding roller and safety net. This greatly improves the ease of use of the device. This design makes the device more efficient in maintaining and replacing parts, providing a reliable guarantee for the safety of the construction site. Attached Figure Description

[0023] Example

[0024] refer to Figures 1 to 4 An emergency management building safety fence according to this embodiment includes two base blocks 1. A concave seat 2 is fixedly installed on the top of the base block 1. A snap-fit ​​mechanism 3 is fixedly installed on the top and bottom of the inner side of the concave seat 2. A winding roller 4 is installed on the inner side of the concave seat 2 through the snap-fit ​​mechanism 3. A protective net 5 is wound on the outer surface of the winding roller 4. The protective nets 5 on the two winding rollers 4 are connected to each other.

[0025] The locking mechanism 3 includes a guide rail 31, which is rotatably connected to the top and bottom of the guide rail 31. A slider 32 is slidably connected inside the guide rail 31. A locking component 33 is fixedly installed on one side of the guide rail 31. The end of the locking component 33 is locked to the slider 32. The inner side of the slider 32 is fixedly connected to both ends of the take-up roller. The concave seat 2 on the top of the two base blocks 1 of this device provides a stable installation base for the safety fence. The locking mechanism 3 inside the concave seat 2 is ingeniously designed. The cooperation between the guide rail 31 and the slider 32 makes the installation and disassembly of the take-up roller 4 more convenient. When the safety fence is needed, the protective net 5 can be quickly unfolded through the take-up roller 4. The protective nets 5 on the two take-up rollers 4 are connected to each other, which can quickly build a safety protection area. The locking component 33 and the slider 32 ensure the stability of the take-up roller 4 during use. At the same time, this structure facilitates the rapid deployment of the safety fence in emergency situations, improves the efficiency of emergency management, and provides reliable safety protection for construction and other scenarios.

[0026] refer to Figures 2-4The snap-fit ​​assembly 33 includes a snap-fit ​​hole 331 and a side frame 332. The side frame 332 is fixedly installed on the outside of the guide rail 31. Torsion springs 333 are fixedly connected to both sides of the inside of the side frame 332. A rotating shaft 334 is rotatably connected to both sides of the side frame 332. The inner end of the rotating shaft 334 is fixedly connected to the outer end of the torsion spring 333. A fixed plate 335 is fixedly connected to the outer end of the rotating shaft 334. A limit rod 336 is fixedly installed at the bottom of the fixed plate 335. The snap-fit ​​hole 331 is opened at both ends of the bottom of the slider 32. The end of the limit rod 336 is inserted into the inside of the snap-fit ​​hole 331. The overall side shape of the snap-fit ​​hole 331 is arc-shaped. The outer end of the limit rod 336 is also arc-shaped. The arc-shaped part of the outer end of the limit rod 336 and the torsion spring 333 are concentric circles. The snap-fit ​​hole 331 is also concentric circles with the torsion spring 333. The side frame 332 consists of the torsion spring 333 and the rotating shaft 334. The components 34 provide a stable installation position. The torsion spring 333 enables the rotating shaft 334 to have an automatic reset function. When it is necessary to fix the slider 32, the rotating shaft 334 drives the limiting rod 336 at the bottom of the fixing plate 335 to rotate, so that the end of the limiting rod 336 is inserted into the arc-shaped locking holes 331 at both ends of the bottom of the slider 32. Since the outer arc of the limiting rod 336 and the torsion spring 333 are concentric, and the locking holes 331 are also concentric with the torsion spring 333, this design ensures that the limiting rod 336 can be accurately inserted into the locking holes 331, achieving a firm locking of the slider 32, thereby ensuring the stability of the winding roller 4 during use. When disassembly is required, simply rotate the rotating shaft 334 to disengage the limiting rod 336 from the locking holes 331. The operation is convenient and quick, improving the deployment and disassembly efficiency of the safety fence in emergency situations.

[0027] refer to Figures 3-4 A handrail 337 is fixedly connected to the outer side of the fixed plate 335. An anti-slip handgrip 338 is fixedly connected to the outer surface of the handrail 337. The inner side of the guide rail 31 and the overall cross-sectional shape of the slider 32 are both convex. A protective cover 6 is hinged to one side of the concave seat 2. The overall cross-sectional shape of the protective cover 6 is U-shaped. A reserved groove 7 is provided on the side of the protective cover 6 away from the hinge with the concave seat 2. The protective net 5 passes through the reserved groove 7 and wraps around the outer surface of the take-up roller 4. The handrail 337 on the outer side of the fixed plate 335 facilitates operation by the operator. The anti-slip handgrip 338 on the outer surface of the handrail 337... 8. The design enhances operational safety and comfort. The convex cross-section of the inner side of the guide rail 31 and the slider 32 makes the slider 32 slide more stably within the guide rail 31, preventing it from falling off. This ensures smooth installation and disassembly of the take-up roller 4. The U-shaped protective cover 6, hinged to one side of the concave seat 2, effectively protects the protective net 5 on the outer surface of the take-up roller 4 during transportation, preventing damage. The reserved groove 7 on one side of the protective cover 6 facilitates the protective net 5 to pass through and wrap around the outer surface of the take-up roller 4, ensuring that the protective net 5 can be easily extended and retracted, thus improving the practicality and durability of the safety fence.

[0028] refer to Figures 1-3 The protective cover 6 has hand-tightened screws 8 threaded at both the upper and lower ends of its outer side. The ends of the hand-tightened screws 8 pass through the protective cover 6 and are threadedly connected to the concave seat 2. The base block 1 has a mounting plate 9 fixedly installed at its bottom. The mounting plate 9 has mounting holes 10 at each of its four corners. The mounting holes 10 are countersunk holes. The hand-tightened screws 8 at both the upper and lower ends of the outer side of the protective cover 6 make the connection between the protective cover 6 and the concave seat 2 firm and reliable. When it is necessary to inspect and maintain the winding roller 4, the protective cover 6 can be easily opened by simply turning the hand-tightened screws 8. The operation is convenient. The mounting plate 9 at the bottom of the base block 1 and the countersunk holes at the four corners make it easy to install the safety fence firmly on different ground surfaces, ensuring the stability of the safety fence during emergency use. The countersunk holes prevent the heads of the mounting bolts from protruding, avoiding safety hazards such as scratches to the surrounding environment and personnel, and improving the overall safety and practicality of the safety fence.

[0029] Operating principle and advantages: By setting up the snap-fit ​​mechanism 3, the protective net 5 on the winding roller 4 inside the concave seat 2 can be unfolded during use, and the entire safety fence can be unfolded smoothly. Since the device adopts the form of protective net 5, it can be unfolded very flexibly during use, especially when protecting irregular construction sites. It can bend adaptably according to actual needs, which greatly facilitates the maintenance of construction sites. In addition, during use, the protective cover 6 is set on the outside of the concave seat 2, which can effectively protect the protective net 5 on the outer surface of the winding roller 4 during movement and transportation, and has a good protective effect. If maintenance is required during use, simply turn the hand screw 8 to rotate and open the protective cover 6, which facilitates the disassembly and assembly of the winding roller 4, and provides great convenience for the disassembly, assembly, replacement and maintenance of the protective net 5.

[0030] By setting up the locking mechanism 3, during use, the fixed plate 335 can be rotated by adjusting the handrail 337. The rotation of the fixed plate 335 will drive the rotating shaft 334 and the limiting rod 336 to rotate. When the limiting rod 336 rotates out of the locking hole 331, the sliding block 32 will lose its limit. During this period, the torsion spring 333 is in a contracted state due to the rotation of the fixed plate 335. At this time, the sliding block 32 can be adjusted to slide out from the inside of the guide rail 31. By pulling the sliding block 32 out from the inside of the guide rail 31, the winding roller 4 and its outer protective net 5 can be quickly disassembled and assembled. After disassembly and maintenance are completed, simply insert the slider 32 into the guide rail 31. Once the slider 32 is installed, release the handrail 337. At this time, the torsion spring 333 will reset and drive the fixed plate 335 to rotate in the opposite direction. Since the limit rod 336 and the locking hole 331 are both concentric with the torsion spring 333, the reset of the fixed plate 335 can drive the limit rod 336 to be accurately inserted into the locking hole 331. Through the mutual limiting and locking of the limit rod 336 and the locking hole 331, the winding roller 4 and the protective net 5 on its outer surface can be quickly replaced and disassembled, greatly improving the convenience of the device during use.
