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.

[0035] Please refer to Figures 1 to 6 , Figure 1 It is a schematic diagram of the exploded structure of the quick-plug connector in the utility model; Figure 2 It is a structural schematic diagram of the internal connector and the external connector in the quick-connect connector of the utility model when they are ready to be plugged in; Figure 3 It is a schematic diagram of the structure after the internal connector and the external connector in the quick-connect connector of the utility model are plugged in; Figure 4 This is one of the structural schematic diagrams of the police climbing frame in the utility model; Figure 5 This is the second structural diagram of the police climbing frame in the utility model; Figure 6 Schematic diagram of the partial explosion structure of the inverted single hook.

[0036] In a specific embodiment, a quick-plug connector 100 provided by the embodiment of the utility model includes an internal connector 1 and an external connector 2. The internal connector 1 is provided with a first elastic block 32 and a second elastic block 42, both of which can be extended and retracted relative to the main body of the internal connector, that is, the first elastic block 32 and the second elastic block 42 can be extended and retracted relative to the main body of the internal connector. The first elastic block 32 and the second elastic block 42 are pre-tightened on both sides of the main body of the internal connector by the pre-support device built into the internal connector 1. The external connector 2 is provided with two slots 21 corresponding to the first elastic block 32 and the second elastic block 42. Among them, when the internal connector 1 and the external connector 2 are buckled, the first elastic block 32 and the second elastic block 42 overcome the tightening force of the pre-support device and retract into the main body of the internal connector, and when the internal connector is plugged into the external connector, the first elastic block 32 and the second elastic block 42 are inserted into the slot 21 of the external connector to lock the internal connector and the external connector.

[0037] When the quick-connect connector 100 is used, the internal connector 1 and the external connector 2 are first fixedly connected to their respective corresponding objects, such as the rod body 200 of the police climbing frame through fasteners.

[0038] After the internal connector 1 and the external connector 2 in this embodiment are plugged and connected, on the one hand, the two elastic blocks (32, 42) on the internal connector 1 can simultaneously clamp the external connector 2, which can increase the connection strength. On the other hand, after the two elastic blocks (32, 42) on the internal connector 1 are clamped into the two slots 21 on the external connector 2, it can be directly seen from the outside whether the two elastic blocks (32, 42) are completely clamped into the two slots 21, which can ensure the connection safety. In addition, when the internal connector 1 and the external connector 2 are to be disassembled, the two elastic blocks (32, 42) must be pressed from the outside at the same time to unlock the internal connector 1 and the external connector 2, and there will be no abnormal unlocking of the internal connector 1 and the external connector 2 after accidentally touching a certain elastic block (32, 42), which further ensures the connection safety.

[0039] Therefore, the quick-connect connector provided in this embodiment has the advantages of high connection strength and high connection safety.

[0040] Based on the above embodiment, the first elastic block 32 and the second elastic block 42 are both provided with plug-in guide surfaces, so that when the inner connector 1 and the outer connector are plugged in, they can be plugged in more smoothly, and only need to align and apply force during plugging, and can be automatically locked.

[0041] Based on the above embodiment, preferably, the plug-in guide surface is the first slope surface 301, which is easy to process. Of course, in other embodiments, a highly gradually changing curved surface may also be used.

[0042] On the basis of the above embodiment, the first elastic block 32 and the second elastic block 42 are both provided with a second slope 302 adjacent to the plug-in guide surface, a first plane 303 adjacent to the second slope 302, and a first vertical surface 304 adjacent to the first plane 303. The first slope 301, the second slope 302, the first plane 303, and the first vertical surface 304 are several continuous surfaces of the inner plug-in connector exposed after the two elastic blocks are tightened. The first vertical surface 304 is provided to clamp the outer plug-in connector 2, and the first plane 303 and the second slope 302 are provided. When disassembling, the protruding position between the first slope 301 and the second slope 302 is pressed to facilitate force, thereby facilitating quick unlocking of the outer plug-in connector 2.

[0043] In some embodiments, the inner plug-in connector includes a first shell and a second shell, and the pre-support device includes a pre-compression spring 5 crimped between a first spring seat 31 and a second spring seat 41 through the first shell 11 and the second shell 12, wherein the first spring seat 31 is located at the bottom of the first elastic block 32, and the second spring seat 41 is located at the bottom of the second elastic block 42. The first shell 11 and the second shell 12 are respectively provided with a first opening 111 and a second opening 121 through which the first elastic block 32 and the second elastic block 42 pass, that is, the first opening 111 is used for the first elastic block 32 to pass, and the second opening 121 is used for the second elastic block 42 to pass. The pre-compression spring 5 in this embodiment is crimped between the first spring seat 31 and the second spring seat 41 through the first shell 11 and the second shell 12, so that the structure of the pre-support device built into the inner connector 1 is simple and reasonable, with fewer parts and components, and convenient installation and manufacturing.

[0044] On the basis of the above embodiment, preferably, the first spring seat 31 and the second spring seat 41 can reciprocate relative to the body of the inner connector 1. Since the first spring seat 31 and the second spring seat 41 are completely located in the inner connector 1, they can always be in contact with the first housing 11 and the second housing 12. Using the first spring seat 31 and the second spring seat 41 as guides can make the guidance smoother.

[0045] On the basis of the above embodiment, a first positioning guide assembly is provided between the first spring seat 31 and the first housing 11, and a second positioning guide assembly is provided between the second spring seat 41 and the second housing 12. The extension direction of the first positioning guide assembly and the second positioning guide assembly are both the same as the axial direction of the pre-compression spring 5. When the overall shape of the first spring seat 31 and the second spring seat 41 is circular rather than square or elliptical, although they can reciprocate relative to the main body of the internal connector 1, they may rotate themselves. Therefore, the positioning guide assembly is provided so that the movement of the two elastic blocks when extending and retracting relative to the internal connector is smoother, avoiding jamming and ensuring the connection safety. On the other hand, it can play a positioning role to avoid the first spring seat 31 and the second spring seat 41 from rotating, thereby avoiding the two elastic blocks from rotating.

[0046] On the basis of the above embodiment, specifically, the first positioning guide assembly includes a first positioning rail 33 arranged on the side of the first spring seat 31 and a first positioning slot arranged on the first housing, which are not shown in the figure. Similar to the second positioning slot 122, the first positioning rail 33 cooperates with the first positioning slot, which can guide the first spring seat 31 to move along the axis of the spring 5 on the one hand, and prevent the first spring seat 31 from rotating on the other hand. The second positioning guide assembly includes a second positioning rail 43 arranged on the side of the second spring seat 41 and a second positioning slot 122 arranged on the second housing 12, which can guide the second spring seat 41 to move along the axis of the spring 5 on the one hand, and prevent the second spring seat 41 from rotating on the other hand.

[0047] On the basis of the above embodiment, the first positioning rail 33 and the second positioning rail 43 are arranged in opposite positions relative to the insertion guide surface. It can also be understood that the arrangement direction of the first positioning rail 33 on the first spring seat 31 is opposite to the arrangement direction of the second positioning rail 43 on the second spring seat 41. The guide is arranged in two opposite directions, so that the overall structure composed of the two elastic blocks (32, 42) and the pre-compression spring 5 has higher guiding properties, and also disperses the weak rigidity of the product on the internal connector 1.

[0048] On the basis of the above embodiments, specifically, a plurality of first countersunk holes (not shown in the drawings, similar to the second countersunk holes) are provided at the edge of the inner end surface of the first shell 11, and a plurality of second countersunk holes 123 are provided at the edge of the inner end surface of the second shell 12. The plurality of first countersunk holes and the plurality of second countersunk holes 123 are arranged in one-to-one correspondence, and a hollow positioning column 6 is placed in the first countersunk hole and the second countersunk hole 123, that is, after the first countersunk hole and the second countersunk hole 123 are aligned, a positioning column 6 is placed in the cavity formed by the first countersunk hole and the second countersunk hole 123. During assembly, the positioning column 6 can be first placed in the first countersunk hole or the second countersunk hole 123, and then the second countersunk hole 123 or the first countersunk hole can be aligned with the positioning column to facilitate positioning when the first shell 11 is connected to the second shell 12.

[0049] In this embodiment, specifically, the first shell 11 and the second shell 12 are both configured in a rectangular parallelepiped shape, a first countersunk hole is provided at each of the four corners of the first shell 11 , and a second countersunk hole 123 is provided at each of the four corners of the second shell 12 .

[0050] The first shell 11 and the second shell 12 are connected by a fastening nut 13 and a fastening bolt 14 passing through the hollow positioning column 6. The hollow positioning column 6 is filled between the first shell 11 and the second shell 12, and can also improve the rigidity of the first shell 11 and the second shell 12 after being connected, and avoid the first shell 11 and the second shell 12 being deformed after a long time after the fastening bolt 14 is pre-tightened.

[0051] On the basis of the above embodiment, a plurality of third countersunk holes 112 are provided at the edge of the outer end surface of the first housing 11, and the third countersunk holes 112 are used to accommodate the head end of the fastening nut 13 or the fastening bolt 13. A plurality of fourth countersunk holes (not shown in the drawings, similar to the third countersunk holes 112) are provided at the edge of the outer end surface of the second housing 12, and the fourth countersunk holes are used to accommodate the head end of the fastening nut 13 or the fastening bolt 14. The third countersunk holes 112 and the fourth countersunk holes are provided to hide the heads of the fastening nuts 13 and the fastening bolts 14, which can improve the aesthetics of the quick-connect connector 100.

[0052] The embodiment of the utility model further provides a police climbing frame, comprising an inverted hook and a multi-section rod 300, wherein the inverted hook and the rod 300 and / or the rods 300 are connected by the aforementioned quick-plug connector 100. Since the police climbing frame comprises the aforementioned quick-plug connector 100, the function and effect are the same as those of the aforementioned quick-plug connector, and will not be described in detail here.

[0053] 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 400, and the purpose of setting the connecting shaft 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.

[0054] In some 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 position of 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. Specifically, embedding grooves 202 are provided on both sides of the hook tip of the inverted single hook 200, and an anti-skid chisel 203 is connected at the position of each embedding groove 201 through a fastener 202, so that the force on the inverted single hook 200 is symmetrically and evenly transmitted to the two anti-skid chisels 203.

[0055] 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.

[0056] The above is a detailed introduction to the quick-plug 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.
