[0002] In air conditioning installation, installers often need to perform tasks such as positioning indoor units, hoisting outdoor units, and laying pipelines at heights on building exteriors. The work locations are dispersed and require frequent relocation, making reliable safety belt anchoring points crucial for personal safety. Traditional fixed anchoring points are mostly pre-installed in the building structure and cannot be flexibly adjusted according to the installation location. In contrast, mobile through-wall safety belt anchoring devices can quickly establish temporary anchoring at the installation site by penetrating the wall, providing safety protection for workers as their work location changes. This has become an indispensable safety guarantee for high-altitude air conditioning installation work.

[0003] However, existing mobile through-wall anchoring devices for air conditioner installation have shortcomings: some devices have poor adaptability to air conditioner installation scenarios and cannot flexibly match the wall thickness and material of different apartment types; some devices lack stability after installation and are prone to loosening due to the hoisting force and vibration during air conditioner installation, posing a risk of falling; some devices are cumbersome to disassemble and can easily cause secondary damage to the wall surface, while lacking intuitive stress status indicators, making it difficult for installers to quickly judge the anchoring reliability, thus posing a safety hazard to high-altitude air conditioner installation operations.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 6This utility model provides a technical solution: a mobile through-wall safety belt anchoring and fastening device, including an anchoring cylinder 1, with storage grooves 2 on both sides of the anchoring cylinder 1. An outer baffle 3 is rotatably fitted to one side of the inner wall of each of the two storage grooves 2. Trapezoidal compression blocks 4 are fixedly connected to opposite sides of each of the two outer baffles 3. An unlocking rod 5 is slidably fitted to the inner wall of the anchoring cylinder 1. An annular compression groove 6, which mates with the two trapezoidal compression blocks 4, is provided on the unlocking rod 5. A return spring 7 is fixedly connected to one side of the inner wall of the anchoring cylinder 1. A threaded groove 8 is provided on the outer side of the anchoring cylinder 1. A locking pressure plate 9 is fitted onto the outer side of the anchoring cylinder 1. A fixing block 10 is fixedly connected to one end of the anchoring cylinder 1. A fastening ring 11 is fixedly connected to one side of the fixing block 10. A limit mechanism 12 is provided on one side of the fixing block 10. One end of the return spring 7 abuts against one end of the unlocking rod 5, and the locking pressure plate 9 is threadedly engaged with the threaded groove 8. The anchoring cylinder 1 is passed through the hole in the wall. The unlocking rod 5, under the action of the reset spring 7, causes the annular extrusion groove 6 to extrude the trapezoidal extrusion block 4, pushing the outer baffle 3 out of the storage groove 2 and pressing it against the inner side of the wall. The locking pressure plate 9 is rotated so that it moves along the threaded groove 8 and presses against the outer side of the wall, quickly completing the device's wall-penetrating fixation and providing a stable foundation for the safety belt to be fastened. The outer baffle 3 and the locking pressure plate 9 cooperate to achieve bidirectional clamping and prevent the device from slipping off.

[0023] In this embodiment, the limiting mechanism 12 includes a U-shaped frame 121 fixedly connected to one side of the fixed block 10. A limiting rod 122 is slidably fitted on the inner wall of the U-shaped frame 121. A limiting groove plate 123 is fixedly connected to one side of the inner wall of the U-shaped frame 121. Limiting rods 124 are fixedly connected to both sides of the limiting rod 122. A compression spring 125 is sleeved on the outer side of the limiting rod 122. A plurality of slots 126 are evenly opened on the circumference of the locking plate 9 near the fixed block 10. One end of the limiting rod 122 passes through the fixed block 10 and is inserted into the slot 126. One end of the limiting rod 124 is engaged with the groove of the limiting groove plate 123. The two ends of the compression spring 125 abut against the U-shaped frame 121 and the limiting rod 124, respectively. After the locking plate 9 is in place, the spring 125 pushes the limiting rod 124 to slide along the limiting groove plate 123, causing the limiting rod 122 to pass through the fixing block 10 and insert into the slot 126, thus limiting the locking plate 9 circumferentially and preventing it from loosening during operation. When unlocking, pull the limiting rod 122 to compress the spring 125, so that the limiting rod 124 can be pulled out and the limiting rod 124 can be engaged with the limiting groove plate 123 to limit the limiting rod 122, thereby achieving limit unlocking and ensuring the ease of installation and disassembly and the stability of use of the device.

[0024] In this embodiment, an assist rod 13 is uniformly fixedly connected to the outer circumference of the locking plate 9. One end of the unlocking rod 5 is fixedly connected to a guide rod 14. A guide groove 15 that mates with the guide rod 14 is provided on one side inside the anchoring cylinder 1. The return spring 7 is sleeved on the outside of the guide rod 14. When the locking plate 9 is rotated, the assist rod 13 can increase the torque, reduce the operating intensity, and improve the assembly and disassembly efficiency. When the unlocking rod 5 moves, the guide rod 14 slides along the guide groove 15 to guide the movement of the unlocking rod 5 and prevent it from deviating. At the same time, the guide rod 14 provides support for the return spring 7 to prevent it from deforming, ensuring that the unlocking rod 5 is accurately reset and ensuring the stable opening and closing of the outer baffle 3.

[0025] When using the device, insert the anchoring cylinder 1 into the wall hole, the reset spring 7 pushes the unlocking rod 5, the annular extrusion groove 6 extrudes the trapezoidal extrusion block 4, causing the outer baffle 3 to rotate out from the storage groove 2 and press against the inner side of the wall; rotate the locking pressure plate 9 by the assist rod 13, so that it moves along the threaded groove 8 and presses against the outer side of the wall; the compression spring 125 pushes the limiting rod 122 into the slot 126 to lock the locking pressure plate 9;

[0026] After use, move the limit rod 124 to pull out the limit insert rod 122, rotate the locking plate 9 in the opposite direction, press the unlocking rod 5 to compress the reset spring 7, the annular extrusion groove 6 extrudes the trapezoidal extrusion block 4, the outer baffle 3 retracts into the storage groove 2, and the device can be taken out, realizing a safe, stable and convenient mobile anchoring and tethering.
