[0025] 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.

[0026] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of the structure of the inverted hook provided by an embodiment of the utility model; Figure 2 A schematic diagram of the structure of the inverted hook provided by an embodiment of the utility model from another angle; Figure 3 A schematic diagram of a partial explosion structure of an inverted single hook provided in an embodiment of the utility model; Figure 4 A schematic structural diagram of a police climbing frame provided in an embodiment of the utility model.

[0027] In a specific implementation, an inverted hook 100 provided by an embodiment of the utility model includes a hook handle 1, to which a plurality of inverted single hooks 2 are fixedly connected, and the plurality of inverted single hooks 2 are staggered at a certain angle in sequence, so that the distance between two adjacent inverted single hooks 2 increases in sequence from the hook handle 1 to the hook tip of the inverted single hook 2 itself.

[0028] Since the inverted hook 100 in this embodiment includes a plurality of inverted single hooks 2, when the inverted hook 100 is supported on the surface of the support body, there are at least two fulcrums between the inverted hook 100 and the support body. Since at least two fulcrums of the inverted single hook 2 will restrict each other, the inverted hook 100 itself can be prevented from tilting left and right. When the inverted hook of this embodiment is used on a police climbing frame, even if the climbing frame is against a smooth arc-shaped abutment surface, the uppermost inverted hook 100 can ensure left and right stability without tilting, thereby stabilizing the rod body at the bottom of the climbing frame, thereby improving the safety performance of the climbing frame.

[0029] On the basis of the above embodiment, the hook bodies of two adjacent inverted single hooks 2 are further fixedly connected by a reinforcing member 3. The reinforcing member 3 is provided between adjacent inverted single hooks 2 to improve the overall rigidity of the inverted hook 100, and to prevent the two adjacent inverted single hooks 2 from being close to each other due to lack of support, thereby failing to limit the skewing of each other.

[0030] On the basis of the above embodiment, preferably, the reinforcement member 3 is a plurality of spaced-apart connecting shafts of unequal lengths, which can stably provide rigid support between the two inverted single hooks 2 .

[0031] In some embodiments, an embedding groove 201 is provided at the hook tip of the inverted single hook 2, and an anti-slip chisel 203 is installed at the position of the embedding groove 201 through a fastener 202, which can greatly improve the anti-slip property of the inverted single hook 2.

[0032] On the basis of the above embodiment, preferably, both sides of the hook tip of the inverted single hook 2 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.

[0033] In some embodiments, a plurality of weight-reducing holes 204 are provided on the hook body of the inverted single hook 2 to reduce the weight of the inverted hook 100, so that the inverted hook 100 has better load-bearing capacity and can be lightweight.

[0034] On the basis of the above embodiment, preferably, two inverted single hooks 2 are fixedly connected to the hook handle 1. Basically, setting two inverted single hooks 2 can meet the use requirements of the scene where the single hook is easy to tilt.

[0035] Based on the above embodiment, the angle between the two inverted single hooks 2 is an acute angle, which facilitates the inverted hook 100 to stably hook on the support surface. If the angle is too large, the two inverted single hooks 2 are too close to the edge of the support body, which is not conducive to hooking safety.

[0036] This embodiment also provides a police climbing frame, including the bar hook 100 described above on the rod body 300, and the hook handle 1 of the bar hook 100 is detachably fixedly connected to the rod body 300. Since the police climbing frame includes the bar hook 100, the function and effect are the same as those of the bar hook 100, and will not be described in detail here.

[0037] In some embodiments, a plurality of anti-skid pedals 400 are fixedly disposed at intervals on the rod body 300, and a V-shaped support frame 500 is also fixedly disposed 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.

[0038] 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.
