[0034] Please also refer to Figures 1 to 6 Now, the lifting hook 100 provided in an embodiment of the present application is described, which is used to connect the fire-fighting equipment 200 with the lifting rope 300.
[0035] See also Figures 1 to 3 The lifting hook 100 includes a hook body 10 and a locking member 20. The hook body 10 includes an elastic bending section 11, a first intermediate section 12, a second intermediate section 13, a first connecting section 14, and a second connecting section 15. One end of the first intermediate section 12 is connected to one end of the elastic bending section 11, and the other end of the second intermediate section 13 is connected to the end of the elastic bending section 11 away from the first intermediate section 12, that is, the first intermediate section 12 and the second intermediate section 13 are respectively connected to the opposite ends of the elastic bending section 11. One end of the first connecting section 14 is connected to the end of the first intermediate section 12 away from the elastic bending section 11, and one end of the second connecting section 15 is connected to the end of the second intermediate section 13 away from the elastic bending section 11, that is, the first connecting section 14 and the second connecting section 15 are respectively connected to the first intermediate section 12 and the second intermediate section 13. The end of the first connecting section 14 away from the first intermediate section 12 is bent toward the second connecting section 15 to form a first hook portion 141. The end of the second connecting section 15 away from the second intermediate section 13 is bent toward the first connecting section 14 to form a second hook portion 151. One end of the locking member 20 is connected to the first intermediate section 12, and the other end of the locking member 20 is engaged with the second intermediate section 13.
[0036] Optionally, the hook body 10 and the locking member 20 are both made of metal. The elastically curved section 11 is capable of bending and elastic deformation. This bending and elastic deformation of the elastically curved section 11 causes the first intermediate section 12 and the second intermediate section 13 to move closer to or farther from each other, thereby causing the first connecting section 14 and the second connecting section 15 to move closer to or farther from each other. The first intermediate section 12 and the second intermediate section 13 are located on the same side of the elastically curved section 11 and are spaced relative to each other. The first connecting section 14 and the second connecting section 15 are spaced relative to each other.
[0037] It should be noted that when one end of the locking member 20 is connected to the first middle section 12 and the other end of the locking member 20 is buckled with the second middle section 13, the first hook portion 141 of the first connecting section 14 and the second hook portion 151 of the second connecting section 15 are in a closed state. Figure 3 , the elastic bending section 11 is in an elastic bending state, and the elastic bending section 11 stores energy, so that the first intermediate section 12 and the second intermediate section 13 have a movement tendency to move away from each other, so that when the other end of the locking member 20 is separated from the second intermediate section 13, the elastic bending section 11 releases energy and elastically expands outward to drive the first intermediate section 12 and the second intermediate section 13 away from each other, and then drives the first connecting section 14 and the second connecting section 15 away from each other, so that the first hook portion 141 of the first connecting section 14 and the second hook portion 151 of the second connecting section 15 are switched from the closed state to the open state, as shown in FIG. Figure 4 .
[0038] Optionally, when the first hook portion 141 of the first connecting section 14 and the second hook portion 151 of the second connecting section 15 are in a closed state, the first hook portion 141 can be in contact with the second hook portion 151, or can be arranged at intervals, as long as in the closed state, the first hook portion 141 and the second connecting section 15 can both be hooked into the hanging hole 201 of the fire-fighting equipment 200.
[0039] Compared with the prior art, the hoisting hook 100 provided by the present application is used to connect the fire-fighting equipment 200 and the hoisting rope 300. First, the locking member 20 is separated from the second middle section 13, and the elastic bending section 11 elastically expands, and the first connecting section 14 and the second connecting section 15 are driven to move away from each other through the first middle section 12 and the second middle section 13. Figure 4 Then, the second hook portion 151 is passed through the eye 301 on the hanging rope 300 until the eye 301 on the hanging rope 300 reaches the elastic bending portion, the first hook portion 141 is hooked into the hanging hole 201 of the fire-fighting equipment 200, and the second intermediate section 13 and / or the second connecting section 15 are pressed to make the second hook portion 151 hooked into the hanging hole 201 of the fire-fighting equipment 200. Finally, the locking member 20 is buckled with the second intermediate section 13 to connect the fire-fighting equipment 200 and the hanging rope 300 together. Figure 2 And such as Figure 3 In this way, by using the lifting hook 100 of the present application to connect the fire-fighting equipment 200 with the lifting rope 300, the operation is simple and convenient, saving time and effort, which is conducive to improving the installation efficiency of the fire-fighting equipment 200.
[0040] It should be noted that the first connecting section 14 and the second connecting section 15 are both rigid structures and are not easily deformed. For example, when the fire-fighting equipment 200 is hung on the wall through the lifting hook 100 and the lifting rope 300, the first hook portion 141 and the second hook portion 151 are not easily deformed under the action of the gravity of the fire-fighting equipment 200, thereby ensuring the stability of the fire-fighting equipment 200 hung on the wall.
[0041] In one embodiment of this application, see Figure 3 and Figure 5 The first middle section 12, the elastic bending section 11 and the second middle section 13 form a U-shaped structure.
[0042] When the other end of the locking member 20 is buckled with the second middle section 13, that is, when the first hook portion 141 of the first connecting section 14 and the second hook portion 151 of the second connecting section 15 are in a closed state, the first middle section 12, the elastic bending section 11 and the second middle section 13 form a U-shaped structure.
[0043] The elastic bending section 11 is in an arc shape, and the first middle section 12 and the second middle section 13 extend in the same direction. Optionally, the first middle section 12 and the second middle section 13 are arranged in parallel and spaced apart.
[0044] When the other end of the locking member 20 is buckled with the second middle section 13, the first middle section 12, the elastic bending section 11 and the second middle section 13 form a U-shaped structure, which effectively prevents the locking member 20 from sliding along the length direction of the first middle section 12 and the second middle section 13, and effectively improves the stability of the connection between the locking member 20 and the first middle section 12 and the second middle section 13.
[0045] Of course, in other embodiments, recesses can be provided in the first middle section 12 and the second middle section 13, and both ends of the locking member 20 can be respectively limited in the recesses of the first middle section 12 and the second middle section 13 to prevent the locking member 20 from sliding along the length direction of the first middle section 12 and the second middle section 13.
[0046] In one embodiment of this application, see Figure 3 and Figure 5 , the first connecting section 14 and the second connecting section 15 are both L-shaped.
[0047] The first connecting section 14 and the second connecting section 15 are both substantially L-shaped.
[0048] The end of the first connecting section 14 away from the first middle section 12 is bent toward the second connecting section 15 to form a first hook portion 141, so that the first connecting section 14 is L-shaped. The end of the second connecting section 15 away from the second middle section 13 is bent toward the first connecting section 14 to form a second hook portion 151, so that the second connecting section 15 is L-shaped.
[0049] By setting the first connecting section 14 and the second connecting section 15 to be L-shaped, the first hook portion 141 and the second hook portion 151 are not easily separated from the hanging hole 201 of the fire-fighting equipment 200, effectively ensuring the stability of the first hook portion 141 and the second hook portion 151 hooked into the hanging hole 201 of the fire-fighting equipment 200, thereby effectively ensuring the stability of the connection between the fire-fighting device and the lifting hook 100.
[0050] Of course, in other embodiments, the first connecting section 14 and the second connecting section 15 may also be V-shaped or arc-shaped.
[0051] In one embodiment of this application, see Figure 3 and Figure 5 The hook body 10 further includes a first transition section 16, which is connected between the first intermediate section 12 and the first connecting section 14. Specifically, one end of the first transition section 16 is connected to the end of the first intermediate section 12 away from the elastically curved section 11, and the other end of the first transition section 16 is connected to one end of the first connecting section 14. That is, one end of the first connecting section 14 is connected to the end of the first intermediate section 12 away from the elastically curved section 11 via the first transition section 16. The first transition section 16 is inclined outward from the first intermediate section 12 to the first connecting section 14.
[0052] The first connecting section 14 is connected to the first intermediate section 12 through the first transition section 16, and the first transition section 16 is inclined outward from the first intermediate section 12 to the first connecting section 14, which is beneficial to increasing the distance between the first connecting section 14 and the second connecting section 15, making it easier to hook the first hook portion 141 and the second hook portion 151 into the hanging hole 201 of the fire-fighting equipment 200, and is beneficial to enhancing the structural strength of the connection between the first connecting section 14 and the first intermediate section 12.
[0053] In one embodiment of this application, see Figure 3 and Figure 5 The hook body 10 further includes a second transition section 17, which is connected between the second intermediate section 13 and the second connecting section 15. Specifically, one end of the second transition section 17 is connected to the end of the second intermediate section 13 away from the elastically curved section 11, and the other end of the second transition section 17 is connected to one end of the second connecting section 15. That is, one end of the second connecting section 15 is connected to the end of the second intermediate section 13 away from the elastically curved section 11 via the second transition section 17. The second transition section 17 is inclined outward from the second intermediate section 13 to the second connecting section 15.
[0054] The second connecting section 15 is connected to the second intermediate section 13 through the second transition section 17, and the second transition section 17 is inclined outward from the second intermediate section 13 to the second connecting section 15, which is conducive to increasing the distance between the second connecting sections 15 and the second connecting sections 15, making it easier to hook the first hook portion 141 and the second hook portion 151 into the hanging hole 201 of the fire-fighting equipment 200, and is conducive to enhancing the structural strength of the connection between the second connecting section 15 and the second intermediate section 13.
[0055] In one embodiment of this application, see Figure 3 and Figure 5 , the hook body 10 is integrally formed.
[0056] As can be understood, the first connecting section 14, the first transition section 16, the first intermediate section 12, the elastically curved section 11, the second intermediate section 13, the second transition section 17, and the second connecting section 15 are integrally formed. By using an integral molding process to manufacture the hook body 10, the overall structural stability of the hook body 10 is effectively ensured, making the hook body 10 less susceptible to breakage during use. Furthermore, the manufacturing process is simple, which helps reduce production costs.
[0057] Of course, in other embodiments, the first connecting section 14 , the first transition section 16 , the first middle section 12 , the elastic bending section 11 , the second middle section 13 , the second transition section 17 and the second connecting section 15 may also be welded together in sequence.
[0058] In one embodiment of this application, see Figure 3 and Figure 6 The locking member 20 includes a sheet 21, a first bent portion 22 and a second bent portion 23. The sheet 21 is arranged between the first middle section 12 and the second middle section 13. The first bent portion 22 is arranged at one end of the sheet 21 and is fixedly buckled with the first middle section 12. The second bent portion 23 is arranged at the other end of the sheet 21 and is buckled with the second middle section 13.
[0059] The locking member 20 includes a plate 21, a first bent portion 22, and a second bent portion 23. The plate 21 is disposed between the first intermediate section 12 and the second intermediate section 13. The first bent portion 22 is disposed at one end of the plate 21 and is fixedly engaged with the first intermediate section 12. The second bent portion 23 is disposed at the other end of the plate 21 and is engaged with the second intermediate section 13. The first bent portion 22 is bent toward the plate 21 so that it and the plate 21 define a first passage 221 through which the first intermediate section 12 passes, thereby enabling the first bent portion 22 to engage with the first intermediate section 12. The second bent portion 23 is bent toward the plate 21 so that it and the plate 21 define a second passage 231 through which the second intermediate section 13 passes. An opening is formed between the second bent portion 23 and the plate 21, communicating with the second passage 231, allowing the second intermediate section 13 to be engaged with the second bent portion 23 from the opening.
[0060] By adopting the sheet 21, the area of the locking member 20 is effectively increased, which is beneficial to enhancing the structural strength of the locking member 20, making the locking member 20 not easily deformed, and effectively ensuring the stability of the locking member 20 in locking the first middle section 12 and the second middle section 13 together. By fixing the first bent buckle portion 22 with the first middle section 12, the stability of the connection between the locking member 20 and the first middle section 12 is effectively guaranteed, and the connection method is simple without the need for additional components. By fastening the second bent buckle portion 23 with the second middle section 13, the connection method is simple and easy to operate.
[0061] It should be noted that the second bend portion 23 is elastic. Under the action of external force, the second bend portion 23 is elastically deformed, so that the second middle section 13 can be buckled into the second bend portion 23 or detached from the second bend portion 23 from the opening of the second bend portion 23.
[0062] In one embodiment of this application, see Figure 3 and Figure 6 The locking member 20 is integrally formed. It is understood that the sheet 21, the first curved portion 22, and the second curved portion 23 are integrally formed. By using an integral molding process to manufacture the locking member 20, the overall structural stability of the locking member 20 is effectively ensured, the manufacturing process is simple, and production costs are reduced.
[0063] In one embodiment of this application, see Figure 6 A guide portion 24 is provided on the second bent portion 23 , and the guide portion 24 is bent toward a side away from the sheet body 21 .
[0064] By providing a guide portion 24 on the second bend portion 23 and bending the guide portion 24 toward the side away from the sheet body 21 , when the second bend portion 23 is buckled with the second middle section 13 , the guide portion 24 guides the second middle section 13 , making it easier for the guide portion 24 to buckle into the second bend portion 23 .
[0065] Optionally, the guide portion 24 and the second buckle portion 23 are integrally formed.
[0066] See also Figure 1 and Figure 2 The present application also provides a fire-fighting assembly, including fire-fighting equipment 200, a lifting rope 300 and a lifting hook 100 of any of the above-mentioned embodiments. The fire-fighting equipment 200 is provided with a hanging hole 201, and a lifting ring 301 is provided at one end of the lifting rope 300. The first hook portion 141 and the second hook portion 151 are hooked into the hanging hole 201, and the elastic bent section 11 passes through the lifting ring 301.
[0067] The end of the hanging rope 300 away from the hanging ring 301 can be connected to a wall, a cabinet, mechanical equipment, etc.
[0068] The firefighting assembly provided by the present application adopts the above-mentioned lifting hook 100. When the firefighting equipment 200 is connected to the lifting rope 300 by using the lifting hook 100 of the present application, the locking member 20 is first separated from the second intermediate section 13, the elastic bending section 11 elastically expands, and the first connecting section 14 and the second connecting section 15 are driven to move away from each other through the first intermediate section 12 and the second intermediate section 13. Then, the second hook portion 151 is passed through the ring 301 on the lifting rope 300 until the ring 301 on the lifting rope 300 reaches the elastic bending portion, and the first connecting section 14 is pulled away from the second connecting section 15. A curved hook portion 141 is hooked into the hanging hole 201 of the fire-fighting equipment 200, and the second middle section 13 and / or the second connecting section 15 are pressed to make the second curved hook portion 151 hooked into the hanging hole 201 of the fire-fighting equipment 200, and finally the locking member 20 is buckled with the second middle section 13 to connect the fire-fighting equipment 200 and the hanging rope 300 together. In this way, by using the lifting hook 100 of the present application to connect the fire-fighting equipment 200 and the hanging rope 300, the operation is simple and convenient, saving time and effort, and helping to improve the installation efficiency of the fire-fighting equipment 200.
[0069] The number of the hanging holes 201 and the number of the hanging hooks 100 can be one or more.
[0070] Optionally, two hanging holes 201 are provided on the top of the fire-fighting equipment 200, and the two hanging holes 201 are respectively provided at both ends of the fire-fighting equipment 200. The number of the hanging ropes 300 and the number of the hanging hooks 100 are both two. The two hanging ropes 300 are respectively connected to the two hanging hooks 100, and the two hanging hooks 100 are respectively connected to the two hanging holes 201 on the fire-fighting equipment 200. By using two hanging ropes 300 in conjunction with two hanging hooks 100, the fire-fighting equipment 200 can be hung, effectively improving the stability of the hanging of the fire-fighting equipment 200 and increasing safety.
[0071] In one embodiment of this application, see Figure 1 and Figure 2 , the fire-fighting equipment 200 is an emergency sign light. Of course, in other embodiments, the fire-fighting equipment 200 can also be a non-luminous fire-fighting sign board or a fire-fighting reminder board.
[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
