[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Please refer to Figures 1 to 5 , Figure 1 A schematic diagram of the explosion structure of a soft resettable connector provided in a specific embodiment of the utility model; Figure 2 A schematic diagram of the structure of a soft repositionable connector provided in a specific embodiment of the utility model; Figure 3 This is one of the structural schematic diagrams of a police climbing frame provided by a specific implementation method of the utility model; Figure 4 The second structural diagram of the police climbing frame provided by a specific implementation method of the utility model; Figure 5 Schematic diagram of the partial explosion structure of the inverted hook.
[0029] In a specific embodiment, a soft resettable connector 100 provided by the utility model includes a soft connecting rope 1 and a tension spring 2, the soft connecting rope 1 is fixedly connected between a first rigid joint 3 and a second rigid joint 4, the tension spring 2 is sleeved on the outside of the soft connecting rope 1 and fixedly supported between the first rigid joint 3 and the second rigid joint 4.
[0030] Since the flexible resettable connector 100 in this embodiment is provided with a tension spring 2 outside the flexible connecting rope, it not only has the load-bearing capacity of the flexible connecting rope 1, and its deformation is very small when carrying heavy objects, but also has the automatic reset performance after bending of the tension spring 2. Therefore, the flexible resettable connector 100 in this embodiment has the advantages of 360-degree self-restoration and high load-bearing capacity.
[0031] In some specific embodiments, the flexible connecting rope 1 can be a steel wire rope, which has the advantages of high bearing strength and small deformation. Of course, in actual use, the flexible connecting rope 1 of other materials can be selected according to the actual bearing requirements and the use environment.
[0032] On the basis of the above embodiment, the first rigid joint 3 includes a first inner rigid joint 31 and a first outer rigid joint 32 sleeved outside the first inner rigid joint 31, one end of the first inner rigid joint 31 is connected to the flexible connecting rope 1, and the other end is detachably fixedly connected to the first outer rigid joint 32. The second rigid joint 4 includes a second inner rigid joint 41 and a second outer rigid joint 42 sleeved outside the second inner rigid joint 41, one end of the second inner rigid joint 41 is connected to the flexible connecting rope 1, and the other end is detachably fixedly connected to the first outer rigid joint 42.
[0033] One end of the tension spring 2 is located in the gap between the first inner rigid joint 31 and the first outer rigid joint 32 , and the other end is located in the gap between the second inner rigid joint 41 and the second outer rigid joint 42 .
[0034] In this embodiment, the first rigid joint 3 and the second rigid joint 4 are configured to be split, and the two ends of the tension spring 2 are limited in the gap between the rigid components. The connection is ingenious, which not only stably supports the tension spring 2 between the first rigid joint 3 and the second rigid joint 4, but also facilitates the disassembly and assembly of the tension spring 2 and the first rigid joint 3 and the second rigid joint 4, and facilitates the replacement of the flexible connecting rope 1.
[0035] In some specific embodiments, the first inner rigid joint 31 and the second inner rigid joint 32 are both embedded fastening pins, the inner end surface of the embedded fastening pin is provided with an inner hole for connecting the flexible connecting rope 1, and the circumferential surface of the embedded fastening pin is also provided with a first connecting hole 71, a second connecting hole 72 and a third connecting hole 73 that penetrate the fastening pin, the axis of each of the first connecting hole 71, the second connecting hole 72 and the third connecting hole 73 is perpendicular to the axis of the embedded fastening pin, the axis directions of the first connecting hole 71 and the second connecting hole 72 are parallel, and the axial directions of the first connecting hole 71 and the third connecting hole 73 are perpendicular. Among them, the first connecting hole 71 is used to connect to the first outer rigid joint 32 through the fastener 5 or to the second outer rigid joint 42 through the fastener 6, and the second connecting hole and the third connecting hole are used for welding the wire rope. The wire rope and the embedded fastening pin are welded together with welding materials in the second connecting hole and the third connecting hole, which can ensure that the connection strength between the wire rope and the embedded fastening pin meets the requirements.
[0036] It is understandable that the end of the first outer rigid joint 32 facing away from the first inner rigid joint 31 is also configured as a male joint or a female joint, and the end of the second outer rigid joint 42 facing away from the second inner rigid joint 41 is also configured as a male joint or a female joint. This facilitates the rapid connection of an object using the soft repositionable connector with other objects.
[0037] The embodiment of the utility model also provides a police climbing frame, including an inverted hook and a multi-section rod body 300, and the inverted hook and the rod body 300 or the rod body 300 and the rod body 300 are connected by the aforementioned soft resettable connector 100. It should be noted that the position of the soft resettable connector 100 relative to the police climbing frame is not fixed, and the length of the soft resettable connector 100 can be 100mm-1000mm. However, when it is used specifically, it can be specifically set according to the performance and usage scenario, and this is not a limitation on its length.
[0038] Since the police climbing frame includes the aforementioned soft resettable connector 100, its function and effect are the same as those of the aforementioned soft resettable connector. In addition, when the soft resettable connector 100 of this embodiment is used on the police climbing frame, the police climbing frame can avoid the protruding objects on the climbing abutment surface (such as the raised part of the ship's flank or the rectangular / trapezoidal raised outer window sill part of the floor window) through the soft resettable connector of this embodiment, so that the police climbing frame under the protruding object can also be stably supported on the climbing abutment surface, so that the police climbing frame can completely abut against the surface of the protruding object, and the lower end of the climbing frame equipment will not be tilted, which is convenient for climbing.
[0039] On the basis of the above-mentioned embodiment, the inverted hook is an inverted single hook 200 or an inverted double hook, and the inverted double hook includes two inverted single hooks 200 fixedly connected together at a certain angle at the hook handle, and the hook bodies of the two inverted single hooks 200 included in the inverted double hook are also connected by multiple connecting shafts 600, and the purpose of setting the connecting shafts 600 is to make the rigidity of the inverted double hook better. When it is necessary to climb a smooth surface such as a hull, the unbalanced left and right pulling force at the bottom of the inverted single hook will cause the inverted single hook to tilt left and right, making the climbing frame unstable. Therefore, when climbing the hull, the inverted hook uses an inverted double hook, which is not easy to tilt. When it is necessary to climb a general building window, since the wall is straight and not smooth, the inverted hook can use an inverted single hook 200.
[0040] In some specific embodiments, an embedding groove 201 is provided at the hook tip of the inverted single hook 200, and an anti-skid chisel 203 is installed at the embedding groove 201 through a fastener 202. The anti-skid chisel 203 is provided at the hook tip of the inverted single hook 200, which can greatly improve the anti-skid property of the inverted single hook 200.
[0041] Based on the above embodiment, preferably, both sides of the hook tip of the inverted single hook 200 are provided with an embedding groove 201, and an anti-slip chisel 203 is connected to each embedding groove 201 through a fastener 202. Thus, the force on the inverted single hook 200 can be symmetrically and evenly transmitted to the two anti-slip chisels 203, making the support more stable and the anti-slip property better.
[0042] In some specific embodiments, a plurality of anti-skid pedals 400 are fixedly arranged at intervals on the rod body 300, and a V-shaped support frame 500 is also fixedly arranged on the rod body 300. The V-shaped support frame 500 abuts against the climbing abutment surface to form a stable triangular support, so that the police climbing frame of this embodiment has good support stability.
[0043] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0044] The above is a detailed introduction to the soft resettable connector and police climbing frame provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model. Therefore, the utility model will not be limited to the embodiments described herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
