Description

Technical Field

[0001] This utility model relates to a suspension device, and more particularly to a suspension device for a fire safety rope, belonging to the field of fire equipment technology. Background Technology

[0002] Fire safety ropes are essential tools for self-rescue and rescue during firefighting. The suspension device is an anchor point used to fix the fire safety rope. It is usually fixed by windowsills or balcony walls. However, in cigarette manufacturing plants, it is often difficult to find suitable fixing points for fire safety ropes, which adds difficulties to firefighting work.

[0003] In addition, the suspension device in the technology is relatively complicated and cumbersome to fix when in use. At the same time, during the escape process, under the influence of the escapee's own weight, the suspension device is easy to detach from the window sill or balcony wall, which is not very safe. Utility Model Content

[0004] The purpose of this invention is to provide a suspension device for fire safety ropes, which has the advantages of simple and safe fixing, and solves the problems mentioned in the background art.

[0005] This utility model provides a suspension device for a fire safety rope, including a top plate, one end of which is fixedly connected to a safety rope. A clamping device is provided on the top plate, the clamping device including a positioning plate and a clamping plate. The upper end of the positioning plate is fixedly connected to the left end of the bottom surface of the top plate, and the clamping plate is movably installed on the top plate through a position adjustment component.

[0006] In the aforementioned suspension device for fire safety ropes, preferably, a plurality of friction strips are formed on the opposing surfaces of the positioning plate and the clamping plate.

[0007] In the aforementioned suspension device for fire safety ropes, preferably, a groove extending along the length direction is provided at the bottom of the top plate, a connecting block is slidably connected to the inner cavity of the groove, and the bottom of the connecting block is fixedly connected to the top of the clamping plate.

[0008] In the aforementioned suspension device for fire safety ropes, preferably, the position adjustment assembly includes a lead screw and a ratchet. A rotation groove and a limiting groove are provided on the left end wall of the slide groove. The limiting groove is located to the left of the rotation groove and the two are connected. The size of the limiting groove is larger than the size of the rotation groove. A circular plate is rotatably mounted on the limiting groove. The left end of the lead screw passes through the rotation groove and is fixedly connected to the circular plate. The right end of the lead screw passes through the right side wall of the top plate and is fixedly connected to the ratchet. The connecting block is threadedly connected to the lead screw.

[0009] In the aforementioned suspension device for the fire safety rope, preferably, a pawl is installed on the right side wall of the top plate via an elastic component, and the pawl engages with the ratchet.

[0010] In the aforementioned suspension device for fire safety ropes, preferably, the elastic component includes a circular hole, a positioning pin, and a torsion spring. The circular hole is located at the end of the pawl away from the ratchet. The positioning pin passes through the circular hole and is threaded to the right side wall of the top plate. The torsion spring is sleeved on the positioning pin, and both ends of the torsion spring are fixedly connected to the inner wall of the circular hole and the surface of the positioning pin, respectively.

[0011] In the aforementioned suspension device for fire safety ropes, preferably, a limiting block is fixedly connected to one side of the pawl, a track groove is provided on one side of the top plate, and the limiting block is slidably connected to the inside of the track groove.

[0012] In the aforementioned suspension device for fire safety ropes, preferably, a stabilizing block is fixedly connected to the top of the connecting block, a stabilizing groove is provided on the top of the top plate, the stabilizing groove communicates with the sliding groove, and the stabilizing block is slidably connected inside the stabilizing groove.

[0013] In the aforementioned suspension device for fire safety ropes, preferably, a sliding rod is fixedly provided in the stabilizing groove, and the stabilizing block is slidably connected to the sliding rod.

[0014] Compared with the prior art, this utility model, by setting a clamping device, allows the connecting block to move inside the sliding groove by rotating the lead screw during fixing. Due to the threaded connection between the lead screw and the connecting block, the connecting block can move synchronously under the limiting action of the sliding groove, thereby driving the clamping plate to move synchronously. This allows the distance between the positioning plate and the clamping plate to be adjusted, making it suitable for walls of different thicknesses and solving the problem of cumbersome fixing methods in the prior art.

[0015] By setting up a position adjustment component, the ratchet, pawl and elastic component can work together to prevent the ratchet from rotating in the forward direction, which would cause the distance between the positioning plate and the clamping plate to increase. This solves the problem in the prior art where the suspension device is easy to detach from the window sill or balcony wall, resulting in poor safety. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Embodiments of this utility model: such as Figures 1-5 As shown, a suspension device for a fire safety rope includes a top plate 1, with a safety rope 2 fixedly connected to one end of the top plate 1. A clamping device 3 is provided on the top plate 1, and the clamping device 3 includes a positioning plate 31 and a clamping plate 32. The upper end of the positioning plate 31 is fixedly connected to the left end of the bottom surface of the top plate 1, and the clamping plate 32 is movably installed on the top plate 1 through a position adjustment component 4. A plurality of friction strips 5 are formed on the opposing surfaces of the positioning plate 31 and the clamping plate 32.

[0024] By setting the clamping device 3 and the position adjustment component 4, the top plate 1 can be fixed to the wall and can be applied to walls of different widths. By setting the friction strip 5, the friction between the positioning plate 31 and the clamping plate 32 and the wall can be increased.

[0025] In this embodiment, the positioning plate 31 and the clamping plate 32 are the same size, both of which are cuboid plates. The positioning plate 31 and the clamping plate 32 are both arranged vertically, and the top plate 1 is arranged horizontally.

[0026] Furthermore, a groove 33 extending along the length direction is provided at the bottom of the top plate 1, and a connecting block 34 is slidably connected to the inner cavity of the groove 33. The bottom of the connecting block 34 is fixedly connected to the top of the clamping plate 32.

[0027] The position adjustment assembly 4 includes a lead screw 35 and a ratchet 41. A rotating groove 36 and a limiting groove 37 are provided on the left end of the groove wall of the slide groove 33. The limiting groove 37 is located to the left of the rotating groove 36 and the two are connected. The size of the limiting groove 37 is larger than the size of the rotating groove 36. A circular plate 38 is rotatably installed in the limiting groove 37. The left end of the lead screw 35 passes through the rotating groove 36 and is fixedly connected to the circular plate 38. The rotating groove 36 is a circular groove, and the diameter of the rotating groove 36 is equal to the diameter of the lead screw 35. The right end of the lead screw 35 passes through the right side wall of the top plate 1 and is fixedly connected to the ratchet 41. The connecting block 34 is threadedly connected to the lead screw 35.

[0028] By rotating the lead screw 35, since the lead screw 35 is threadedly connected to the connecting block 34, the connecting block 34 can move inside the sliding groove 33 under the limiting action of the sliding groove 33, thereby driving the clamping plate 32 to move synchronously. This allows the distance between the positioning plate 31 and the clamping plate 32 to be adjusted, which is suitable for walls of different thicknesses.

[0029] By setting the rotating groove 36, the limiting groove 37 and the circular plate 38, the lead screw 35 can be limited to prevent it from shifting horizontally.

[0030] Furthermore, a pawl 42 is installed on the right side wall of the top plate 1 via an elastic component 43, and the pawl 42 engages with the ratchet 41. The elastic component 43 includes a circular hole 431, a locating pin 432, and a torsion spring 433. The circular hole 431 is located at the end of the pawl 42 away from the ratchet 41. The locating pin 432 passes through the circular hole 431 and is threadedly connected to the right side wall of the top plate 1. The torsion spring 433 is sleeved on the locating pin 432, and both ends of the torsion spring 433 are fixedly connected to the inner wall of the circular hole 431 and the surface of the locating pin 432, respectively.

[0031] By setting the ratchet 41, pawl 42, and elastic component 43, the lead screw 35 can be limited to prevent it from rotating backward and to prevent the clamping plate 32 from loosening. In this embodiment, viewed from the right side of the top plate 1, the distance between the clamping plate 32 and the positioning plate 31 decreases when the ratchet 41 rotates counterclockwise, and increases when the ratchet 41 rotates clockwise. However, under the elastic action of the torsion spring 433, the ratchet 41 and the pawl 42 abut against each other, and the ratchet 41 will not rotate clockwise automatically, thus avoiding an increase in the distance between the positioning plate 31 and the clamping plate 32, thereby increasing the stability of the top plate 1 after it is fixed. When the ratchet 41 needs to be rotated clockwise to clamp the top plate 1 to the wall, the pawl 42 needs to be manually pushed upward so that the pawl 42 rotates in a circle around the axis of the positioning pin 432. At this time, the torsion spring 433 is coiled. After the fixing is completed, under the action of the restoring force of the torsion spring 433, the pawl 42 is locked in the slot on the surface of the ratchet 41 to complete the fixing. When the ratchet 41 rotates counterclockwise, it moves up and down reciprocatingly under the elastic action of the torsion spring 433 without the need for external force interference.

[0032] Furthermore, a limiting block 44 is fixedly connected to one side of the pawl 42, and a track groove 45 is provided on one side of the top plate 1. The limiting block 44 is slidably connected inside the track groove 45. When the pawl 42 rotates, the limiting block 44 rotates synchronously inside the track groove 45, which can increase the stability of the pawl 42.

[0033] Furthermore, a stabilizing block 39 is fixedly connected to the top of the connecting block 34, and a stabilizing groove 391 is provided on the top of the top plate 1. The stabilizing groove 391 communicates with the sliding groove 33, and the stabilizing block 39 is slidably connected inside the stabilizing groove 391. A sliding rod 392 is fixedly provided inside the stabilizing groove 391, and the stabilizing block 39 is slidably connected to the sliding rod 392.

[0034] By setting the stabilizing block 39 and the stabilizing groove 391, the stability of the connecting block 34 can be increased; by setting the sliding rod 392, the stability of the stabilizing block 39 can be increased, thereby increasing the stability of the clamping plate 32.

[0035] The working principle of this utility model is as follows: By rotating the ratchet 41, the lead screw 35 is driven to rotate. Since the lead screw 35 and the connecting block 34 are threadedly connected, the connecting block 34 can move inside the sliding groove 33 under the limiting action of the sliding groove 33, thereby driving the clamping plate 32 to move synchronously. This allows adjustment of the distance between the positioning plate 31 and the clamping plate 32, which is suitable for walls of different thicknesses. When the top plate 1 needs to be clamped on the wall and the ratchet 41 needs to rotate in the forward direction, the pawl 42 is pushed upward, so that the pawl 42 rotates in a circle around the axis of the positioning pin 432. At this time, the torsion spring 433 is coiled. After the fixing is completed, under the action of the restoring force of the torsion spring 433, the pawl 42 is clamped in the groove on the surface of the ratchet 41 to complete the fixing. When the ratchet 41 rotates in the reverse direction, it moves up and down reciprocatingly under the elastic action of the torsion spring 433 without the need for external force interference.

The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
