Description

Technical Field

[0001] The utility model relates to a wall hanging component, in particular to a wall hanging component for a fire safety rope, belonging to the technical field of safety rope wall hanging equipment. Background Art

[0002] A fire safety rope is a type of rope designed specifically for rescue and escape in fire or emergency situations. It is commonly used by firefighters, high-rise building residents, and others who need to quickly evacuate dangerous areas. The primary function of a fire safety rope is to help users safely descend from heights to the ground, or to assist in self-rescue and mutual rescue in complex environments.

[0003] Bolts are the most common way to secure a fire safety rope. During installation, you drill a hole in the wall, insert the bolt into the hole, and tighten it with a tool. When the bolt is tightened, it grips the hole wall tightly, forming a secure fixing point.

[0004] In actual applications, the effectiveness of bolts is highly dependent on the quality and material of the wall. If the wall material is poor, such as old or fragile concrete or hollow bricks, bolts are prone to loosening. To address this, we offer a wall-mounted component for fire safety ropes. Utility Model Content

[0005] The utility model provides a wall-hanging component for a fire safety rope, which can be firmly fixed on a wall and effectively prevents it from becoming loose.

[0006] The utility model is implemented through the following technical solutions: comprising a mounting assembly, the mounting assembly comprising a mounting shell and a fixing plate, a fixing mechanism for fixing the mounting shell and the fixing plate being arranged between the mounting shell and the fixing plate.

[0007] The locking mechanism comprises a first locking plate, a second locking plate, and a second locking plate, wherein the locking plate has a first end fixed to the locking plate and a second end of the locking plate is engaged with the first and second locking plates, wherein the locking plate has a first locking plate and a second end of the locking plate is engaged with the first and second locking plates.

[0008] Specifically, a positioning spring is fixed on the side where the second protrusion and the threaded barrel are close to each other.

[0009] Specifically, an indicator arrow A is fixed on the inner wall of the mounting shell, and an indicator arrow B is fixed on a side of the threaded barrel away from the first protrusion.

[0010] Furthermore, the axes of the limiting rod, the first limiting hole, and the second limiting hole are on the same horizontal line, the limiting rod is loosely matched with the first limiting hole, and the limiting rod is loosely matched with the second limiting hole.

[0011] Specifically, the spring telescopic rod includes a spring cylinder embedded in the inner wall of the fixed plate, a second compression spring is fixed to the inner wall of the spring cylinder, and a moving rod is fixed to the other end of the second compression spring. The side of the moving rod close to the threaded cylinder is fixed to the trapezoidal block, and the side surface of the trapezoidal block is in sliding contact with the inner wall of the spring cylinder.

[0012] Furthermore, the front of the mounting shell is rotatably connected to a box door, and a handle is fixed on the box door.

[0013] Specifically, a plurality of mounting plates are fixed on the mounting shell and the fixing plate, and a storage tube is fixed on the inner wall of the mounting shell.

[0014] The utility model provides a wall-mounted assembly for a fire safety rope, which has the following beneficial effects:

[0015] The wall-hanging component of the fire safety rope arranges the mounting shell and the fixing plate on the two sides of the wall respectively, and fixes the mounting shell and the fixing plate through a threaded barrel, so that the device can be subjected to force from two directions at the same time, dispersing the pressure of the force point, avoiding local stress concentration caused by force in a single direction, thereby enhancing the fixing strength. At the same time, the first protrusion can be limited by the second limiting hole in conjunction with the limiting rod, so that the first protrusion cannot rotate and slide, and then the sliding rod and the threaded barrel are both limited and cannot rotate, effectively preventing the threaded barrel from rotating on its own due to external vibration, impact or repeated load changes, and effectively preventing the bolts from gradually loosening during long-term use.

[0028] Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6A fixing mechanism 2 for fixing the mounting shell 101 and the fixing plate 102 is provided between the mounting shell 101 and the fixing plate 102. The fixing mechanism 2 includes a threaded cylinder 201 threadedly connected to the mounting shell 101. The inner wall of the threaded cylinder 201 is slidably connected to a slide rod 202. A slide bar 2021 is fixed to the side of the slide rod 202. The inner wall of the threaded cylinder 201 is provided with a groove adapted to the slide bar 2021. The grooves provided by the slide bar 2021 and the inner wall of the threaded cylinder 201 allow the slide rod 202 to slide only in the threaded cylinder 201. , cannot rotate, the other end of the threaded cylinder 201 is threadedly connected to the fixed plate 102, and a first protrusion 203 is fixed to the end of the sliding rod 202 close to the fixed plate 102, and a limiting rod 2031 is fixed to the side of the first protrusion 203, and the side of the sliding rod 202 is slidably connected to the second protrusion 204 through the sliding bar 2021. The second protrusion 204 can only slide on the sliding rod 202 and cannot rotate. A first limiting hole 2041 is opened on the second protrusion 204, and the limiting rod 2031 is clearance-matched with the first limiting hole 2041.

[0029] Please refer to Figure 4 The inner wall of the fixed plate 102 is provided with a spring telescopic rod 3, and the spring telescopic rod 3 includes a spring cylinder 301 embedded in the inner wall of the fixed plate 102. The inner wall of the spring cylinder 301 is fixed with a second compression spring 302, and the other end of the second compression spring 302 is fixed with a moving rod 303. The side of the moving rod 303 close to the threaded cylinder 201 is fixed to the trapezoidal block 205, and the side of the trapezoidal block 205 is in sliding contact with the inner wall of the spring cylinder 301. When the trapezoidal block 205 moves on the inner wall of the spring cylinder 301, the second compression spring 302 will be squeezed by the moving rod 303, causing the second compression spring 302 to deform.

[0030] A trapezoidal block 205 is fixed on the spring telescopic rod 3, and a second limiting hole 2051 is opened on the trapezoidal block 205. The limiting rod 2031 is clearance-matched with the second limiting hole 2051. The axes of the limiting rod 2031, the first limiting hole 2041, and the second limiting hole 2051 are on the same horizontal line. A stop block 206 is fixed on the side of the sliding rod 202 near one end of the first protrusion 203.

[0031] A fixing ring 207 is fixed to the side of the slide bar 202, and a first compression spring 208 is fixed to the side of the fixing ring 207 close to the first protrusion 203. When the fixing ring 207 moves toward the fixed plate 102 driven by the slide bar 202, the first compression spring 208 will be squeezed, causing the first compression spring 208 to deform. A positioning spring 209 is fixed to the side where the second protrusion 204 and the threaded cylinder 201 are close to each other. The elastic force of the positioning spring 209 is relatively small, and the positioning spring 209 plays a role in positioning the second protrusion 204, preventing the first protrusion 203 from fitting into the first limiting hole 2041 when the first protrusion 203 is pushed by the slide bar 202, so that the trapezoidal block 205 cannot be inserted between the first protrusion 203 and the second protrusion 204.

[0032] Please refer to Figure 4 and Figure 5 When the device needs to be disassembled, the slide bar 202 is continued to be pushed. The slide bar 202 will drive the second protrusion 204 to squeeze the inclined surface of the trapezoidal block 205 through the stop block 206. After the trapezoidal block 205 moves to the inside of the spring tube 301, the trapezoidal block 205 will press against the inclined surface of the second protrusion 204 under the elastic force generated by the second compression spring 302. At this time, the slide bar 202 is stopped. Under the elastic force generated by the deformation of the first compression spring 208, the slide bar 202 will drive the first protrusion 203 to move closer to the second protrusion 204 until the second protrusion 204 and the first protrusion are aligned. 203 fit together, at this time the limiting rod 2031 will also be inserted into the first limiting hole 2041, after the first protrusion 203 fits together with the second protrusion 204, the trapezoidal block 205 will move to the inclined surface of the first protrusion 203, at this time the limiting rod 2031 no longer limits the first protrusion 203 through the second limiting hole 2051, and the threaded barrel 201 can be rotated to release the fixed state of the fixing plate 102 and the mounting shell 101. An indicator arrow A210 is fixed on the inner wall of the mounting shell 101, and an indicator arrow B211 is fixed on the side of the threaded barrel 201 away from the first protrusion 203.

[0033] Working principle: When in use, first install the installation shell 101 and the fixing plate 102 on the two sides of the wall 4 respectively, and fix the installation shell 101 and the fixing plate 102 through the threaded cylinder 201, so that the device can be stressed from two directions at the same time, avoiding local stress concentration caused by stress in a single direction. At this time, the first protrusion 203 is located on the right side of the trapezoidal block 205, and the sliding rod 202 is pushed to drive the first protrusion 203 to squeeze the inclined surface of the trapezoidal block 205, so that the trapezoidal block 205 slides on the inner wall of the spring cylinder 301 until the first protrusion 203 moves to the trapezoidal block 205. On the left side, the elastic force generated by the first compression spring 208 squeezed by the fixing ring 207 will cause the first protrusion 203 to drive the limiting rod 2031 to be inserted into the second limiting hole 2051, and then the first protrusion 203 can be limited by the second limiting hole 2051 in cooperation with the limiting rod 2031, so that the first protrusion 203 cannot rotate or slide, and the sliding rod 202 and the threaded barrel 201 are both limited and cannot rotate, effectively preventing the threaded barrel 201 from rotating on its own due to external vibration, impact or repeated load changes, and effectively preventing the bolt from gradually loosening during long-term use.
