Description

Technical Field

[0001] This utility model relates to the field of fire escape technology, and in particular to a quick-installation structure for a fire escape descent device. Background Technology

[0002] A fire escape descent device is an escape equipment that allows people to safely descend from a height in emergency fire situations. It mainly consists of a rope, speed controller, safety belt, and other components. The user fastens the safety belt and controls the descent speed through the speed controller of the descent device, allowing the person to descend smoothly and slowly to the ground along the rope. It provides a reliable escape method for people trapped at heights and is suitable for the escape needs of various buildings such as homes, offices, and hotels.

[0003] The quick-installation structure of fire escape descent devices is designed for rapid activation in emergencies. It mainly includes easily secured hooks or rings, which, with the aid of expansion bolts, allow for quick installation on stable structures such as solid walls and beams. The expansion bolts are generally no less than 12 mm in diameter to ensure secure installation. Some devices are also equipped with specialized installation tools to fit locations such as building windows, balconies, or rooftops. Some descent devices can be quickly installed using pre-installed fixing rings on the wall; others are designed to be temporarily suspended from sturdy window or balcony railings for quick deployment in emergencies, allowing trapped individuals to escape quickly. However, during repeated installation and disassembly, the threads are prone to wear and stripping, affecting the reliability of the connection. In emergency situations, if thread damage is discovered, the descent device may fail to install properly or become loose during use. Existing technologies address this by adding anti-loosening devices to the threaded connection, such as spring washers, double nuts, or nylon ring lock nuts. Spring washers deform elastically after tightening the nut, applying additional friction to prevent loosening. Double nuts utilize the friction between the two nuts to prevent loosening by tightening a secondary nut onto the main nut. Nylon ring lock nuts embed a nylon ring at one end of the nut; when tightened, the nylon ring deforms and grips the bolt, locking it in place. However, differences in wall thickness, window location, and structure exist in various buildings. Since the length of the mounting bracket cannot be changed, the descent device may be installed in an inappropriate position, such as too far from or too close to the window, affecting escape efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick installation structure for a fire escape descent device. It aims to improve the problem that in the existing technology, the wall thickness, window position and structure of different buildings are different. Since the length of the installation bracket cannot be changed, the installation position of the descent device is unreasonable, such as being too far away from or too close to the window, which affects the escape efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a quick-installation structure for a fire escape descent device, comprising a housing, a telescopic block fixedly connected to the top left side of the housing, an installation plate mounted on the front side of the telescopic block, a drive gear rotatably connected to the middle of the top inner side of the housing, a driven gear rotatably connected to the top inner side of the housing, the bottom of the driven gear meshing with the top of the drive gear, a threaded rod fixedly connected to the middle of the driven gear, a moving block threadedly connected to the outer side of the threaded rod, the front side of the moving block fixedly connected to the rear end of the installation plate, bolts threadedly connected to both the left and right ends of the installation plate, a safety buckle mounted on the middle outer side of the installation plate, the descent device body mounted at the bottom of the safety buckle, and a telescopic mechanism mounted on the right inner side of the housing, the telescopic mechanism facilitating installation and use by personnel.

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.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a fire escape descent device quick-installation structure, including a housing 1. A telescopic block 14 is fixedly connected to the top left side of the housing 1. An installation plate 11 is installed on the front side of the telescopic block 14. A drive gear 18 is rotatably connected to the middle of the top inner side of the housing 1. A driven gear 19 is rotatably connected to the top inner side of the housing 1. The bottom of the driven gear 19 meshes with the top of the drive gear 18. A threaded rod 16 is fixedly connected to the middle of the driven gear 19. A moving block 17 is threadedly connected to the outer side of the threaded rod 16. The front side of the moving block 17 is connected to the installation plate 11. The rear end of the plate 11 is fixedly connected, and bolts 15 are threadedly connected to both the left and right ends of the mounting plate 11. The installation of bolts 15 makes the mounting plate 11 more stable. A safety buckle 8 is installed in the middle of the outer side of the mounting plate 11. The bottom of the safety buckle 8 is installed with the main body 7 of the slow descent device. A telescopic mechanism 2 is installed on the right side of the inside of the box 1. The telescopic mechanism 2 facilitates the installation and use by the staff. A fixed short column 9 is fixedly connected to the front side of the drive gear 18. A turntable 20 is fixedly connected to the outer side of the fixed short column 9. The installation of the turntable 20 facilitates the rotation of the drive gear 18.

[0032] Specifically, first, the turntable 20 is rotated, and then the fixed short column 9 rotates accordingly. Subsequently, the drive gear 18 starts to rotate under the action of the turntable 20, and drives the driven gear 19 to rotate. Since there is a meshing transmission relationship between the drive gear 18 and the driven gear 19, the rotation of the driven gear 19 drives the threaded rod 16 to rotate. The rotation of the threaded rod 16 causes the moving block 17 to move along its outer side, thereby pushing the mounting plate 11 to move back and forth, realizing the rapid adjustment of the position of the mounting plate 11 to adapt to various different installation requirements.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The telescopic mechanism 2 includes a telescopic short column 205, which is installed in the middle of the right side of the inner side of the box body 1. A shelf 201 is fixedly connected to the front side of the telescopic short column 205. A slide groove 208 is provided on the right side of the inner side of the box body 1. A sliding short column 203 is slidably connected to the top of the inner side of the slide groove 208. The slide groove 208 facilitates the movement of the sliding short column 203. A connecting rod 204 is fixedly connected to the bottom of the sliding short column 203, and the bottom of the connecting rod 204 passes through it. A fixed short plate 206 is fixedly connected to the bottom of the box body 1. A rotating plate 202 is rotatably connected to the front side of the sliding short column 203. A rotating short column 207 is rotatably connected to the front side of the rotating plate 202. The front side of the rotating short column 207 is rotatably connected to the top rear side of the shelf 201. A pull ring 13 is fixedly connected to the bottom of the fixed short plate 206. A connecting bent rod 12 is rotatably connected to the bottom of the box body 1. By installing the connecting bent rod 12, the position of the pull ring 13 can be fixed.

[0034] Specifically, first, pull the ring 13, which causes the connecting rod 204 to move downward. Then, the sliding short column 203 slides downward in the groove 208, which drives the rotating plate 202 to rotate. At the same time, the rotating short column 207 also starts to rotate and pushes the shelf 201 forward. When it is necessary to fix the position of the connecting rod 204, rotate the connecting bent rod 12 so that its end passes through the ring 13 and is locked. Through this series of steps, the shelf 201 can adjust its position and realize the telescopic function, which makes it convenient for users to use.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A connecting cylinder 21 is installed on the top of the box body 1. A box cover 3 is fixedly connected to the front side of the connecting cylinder 21. A handle 4 is installed on the top front side of the box cover 3. Screws 5 are threaded to both the left and right ends of the handle 4. A storage box 6 is fixedly connected to the bottom left side of the inside of the box body 1. An instruction manual 10 is installed inside the storage box 6.

[0036] Specifically, the installation of the cover 3 prevents unnecessary damage when the device is not in use; the installation of the handle 4 facilitates the opening and closing of the cover 3; and the installation of the storage box 6 facilitates the storage of small parts.

[0037] Working principle: First, rotate the turntable 20, which causes the fixed short column 9 to rotate, thereby causing the drive gear 18 to rotate and drive the driven gear 19 to rotate. Since the drive gear 18 and the driven gear 19 mesh and transmit power, the driven gear 19 drives the threaded rod 16 to rotate. The rotation of the threaded rod 16 causes the moving block 17 to move along its outer side, thereby driving the mounting plate 11 to move back and forth, realizing the rapid adjustment of the position of the mounting plate 11 to meet different installation requirements.

[0038] First, pull the ring 13, which causes the connecting rod 204 to move downward, and then the sliding short column 203 to slide downward in the slide groove 208, thereby driving the rotating plate 202 to rotate. At the same time, the rotating short column 207 rotates and pushes the shelf 201 forward. When it is necessary to fix the position of the connecting rod 204, rotate the connecting bent rod 12 so that its end passes through the ring 13 and is fixed. Through the above process, the shelf 201 can be adjusted in position and achieve the effect of telescopic movement, which is convenient for users.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
