Description

Technical Field

[0001] The utility model relates to the technical field of police equipment, in particular to a quick self-locking structure and a long baton comprising the same. Background Art

[0002] Police batons are mainly carried by police officers when they are on duty. In order to facilitate storage, traditional long batons often use telescopic structures, threaded connections or pin connection structures to connect multiple batons. Among them, telescopic batons require batons of different diameters, which affects the feel of use. The pin connection structure is to connect the elastic pin by clamping it on the pin hole. Since the elastic pin is located inside, it is difficult to align the elastic pin with the pin hole during installation. When disassembling, it is necessary to press the elastic pin with a large force to unlock it. The long baton with a threaded connection structure has no circumferential limit, and the locking effect will be reduced after frequent disassembly and assembly. It is easy to rotate relative to each other and loosen during use, resulting in reduced reliability.

[0003] In summary, how to design a long baton with good connection reliability and convenient and quick operation is a technical problem that needs to be solved at present. Utility Model Content

[0004] In order to solve the technical problems in the prior art of detachable long batons such as inconvenient disassembly, poor feel in use or low reliability in use, the utility model provides a quick self-locking structure and a long baton containing the same to solve the above problems.

[0005] The utility model proposes a quick self-locking structure, including a self-locking part, which includes a sleeve, an unlocking button, an elastic reset part and a locking hook. The sleeve includes a mounting portion and a first connecting portion and a second connecting portion located at both axial ends of the mounting portion and capable of inserting two adjacent parts to be connected. The mounting portion has a mounting hole for the unlocking button to pass through, and a fixing seat is provided in the first connecting portion.

[0006] The first connecting portion is fixedly connected to one of the components, and a locking hole is provided on the other component. The middle part of the lock hook is hinged to the unlocking button, one end of the lock hook is a fixed end hinged to the fixing seat, and the other end of the lock hook is a locking end that extends into the locking hole under the action of the elastic return member. The locking end fixes the component connected to it, or the locking end and the second connecting portion jointly fix the component connected to it.

[0007] Furthermore, the fixed end and the fixed seat are rotatably connected to the rotating shaft, and the elastic reset member is a torsion spring sleeved on the rotating shaft. One end of the torsion spring is fixed, and the other end is driven to rotate by the lock hook.

[0008] Furthermore, one end of the torsion spring rests against the surface of the fixing seat, and the other end is bent to form a U-shaped rod. The U-shaped rod is located on the side of the lock hook away from the unlocking button. When the unlocking button is pressed, the torsion spring contracts.

[0009] Furthermore, the cross section of the locking hole is a closed loop shape.

[0010] Furthermore, the cross section of the locking hole is a U-shaped structure that opens toward the mounting portion, and the second connecting portion is threadedly connected to a component connected to the locking end.

[0011] Furthermore, a chamfer is provided on a side of the locking end away from the fixing end.

[0012] Furthermore, it also includes a connecting piece connected to the locking end, the connecting piece includes a third connecting part and a locking part, the locking hole is located in the locking part, the second connecting part is located in the locking part, and the third connecting part is provided with an external thread.

[0013] The present invention also provides a long baton, comprising one or more baton bodies and the above-mentioned rapid self-locking structure, wherein the first connecting portion and the second connecting portion of the rapid self-locking structure respectively connect two adjacent baton bodies.

[0014] The present invention further provides a long baton, comprising one or more baton bodies and the above-mentioned rapid self-locking structure, wherein the first connecting portion and the third connecting portion of the rapid self-locking structure respectively connect two adjacent baton bodies.

[0015] Furthermore, both ends of each baton body are respectively connected with a self-locking part and a switching part, and the baton body at the end of the long baton is connected with a window-breaking end and / or a multifunctional connecting end.

[0016] The beneficial effects of the utility model are:

[0017] (1) The present invention utilizes a lock hook on a self-locking part to connect with adjacent parts. Pressing an unlock button can contact the lock. Since the unlock button presses the middle of the lock hook, the required pressing force is smaller than that of directly pressing the elastic pin in the traditional structure, and the unlocking is faster.

[0018] (2) The quick self-locking structure of the utility model is connected by a self-locking part and an adapter. The self-locking part and the adapter can be directly installed on the stick body. When they need to be used, the self-locking part and the adapter can be directly connected. There is no need to frequently disassemble the stick body, which reduces the wear on the connection parts of the stick body.

[0019] (3) In the present invention, the self-locking part and the adapter are connected by threads and locked circumferentially by a locking hook, thereby improving the connection strength between the two and preventing the long baton from being disassembled and disconnected due to relative rotation during use.

DETAILED DESCRIPTION

[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] Example 1

[0030] A quick self-locking structure is used to connect two adjacent police equipment, for example, a stick body 9 can be connected to a stick body 9, or a stick body 9 can be connected to a window breaking end 13.

[0031] The fast self-locking structure in this embodiment is the self-locking member 1, and the two ends of the self-locking member 1 are directly connected to two police equipment (the schematic diagram of this embodiment is not shown in the accompanying drawings). Figure 3As shown, the self-locking part 1 includes a sleeve 2, an unlocking button 3, an elastic reset part 4 and a locking hook 5. The sleeve 2 includes a mounting portion 201 and a first connecting portion 202 and a second connecting portion 203 located at both axial ends of the mounting portion 201 and capable of inserting two adjacent parts to be connected. The mounting portion 201 has a mounting hole 2011 for the unlocking button 3 to pass through, and a fixing seat 6 is provided in the first connecting portion 202.

[0032] The first connecting portion 202 is fixedly connected to one of the components, and a locking hole 7 is provided on the other component. The middle part of the lock hook 5 is hinged to the unlocking button 3. One end of the lock hook 5 is a fixed end 501 hinged to the fixing seat 6, and the other end of the lock hook 5 is a locking end 502 that extends into the locking hole 7 under the action of the elastic return member 4. The locking end 502 fixes the component connected to it.

[0033] This embodiment is described by taking the connection of two stick bodies 9 as an example. The first connecting part 202 is fixedly connected to one of the stick bodies 9, which can be welded, screwed or threaded. In this embodiment, an external thread is provided on the outer peripheral surface of the first connecting part 202. The first connecting part 202 is inserted into the stick body 9 and locked and fixed with the stick body 9. The locking hole 7 is located at the end of the other stick body 9, and the cross-section of the locking hole 7 is a closed loop figure. The connection effect can be achieved only by the locking hole 7 and the locking end 502. At this time, the second connecting part 203 does not play a fixing role. The second connecting part 203 is inserted into the stick body 9 to play an axial limiting role.

[0034] When the unlocking button 3 is pressed, the elastic reset member 4 is compressed, and the lock hook 5 rotates relative to the fixed end 501, thereby driving the locking end 502 of the lock hook 5 to move away from the locking hole 7, thereby unlocking the two stick bodies 9. When the unlocking button 3 is released, the elastic reset member 4 is reset, driving the lock hook 5 to reset. Therefore, when the locking end 502 of the lock hook 5 is facing the locking hole 7, the self-locking member 1 can be connected to the stick body 9 with the locking hole 7 under normal conditions.

[0035] Since the unlocking button 3 acts on the middle part of the lock hook 5, compared with the traditional structure of directly pressing the elastic pin, the utility model can use the lever principle to reduce the pressing force and improve the disassembly and assembly efficiency. In addition, the unlocking button 3 is exposed to the outside, and it is easy to align the locking end 502 with the locking hole 7 during installation.

[0036] When disassembling the two stick bodies 9, it is only necessary to separate the self-locking part 1 and the stick body 9 connected to its locking hook 5, while the stick body 9 connected to its first connecting part 202 can remain normally connected and does not need to be frequently disassembled, thereby avoiding thread wear on the stick body 9.

[0037] When each stick body 9 has the same structure, one end of each stick body 9 is connected to the first connecting part 202, and the other end is provided with a mounting hole 2011. The self-locking parts 1 on adjacent stick bodies 9 cooperate with the mounting holes 2011 to realize the connection of multiple stick bodies 9 to form a long baton.

[0038] The outer diameter of the sleeve 2 can be the same as the outer diameter of the stick body 9. When the self-locking member 1 connects the two stick bodies 9, the overall outer diameter is consistent, there is no uneven area, and the hand feel is better when used.

[0039] The elastic reset member 4 may be provided with the following structure:

[0040] The fixed end 501 and the fixing seat 6 are rotatably connected to the rotating shaft 8. The elastic reset member 4 is a torsion spring sleeved on the rotating shaft 8. One end of the torsion spring is fixed and can directly abut the surface of the fixing seat 6 or be welded to the fixing seat 6. The other end is driven to rotate by the lock hook 5. Under normal conditions, the torsion spring exerts a radial outward force on the lock hook 5, causing the locking end 502 to tilt outward and be inserted into the locking hole 7. When the unlocking button 3 is pressed, the lock hook 5 drives the end of the torsion spring to rotate, causing the torsion spring to deform. Figure 4 As shown, one end of the torsion spring that moves with the lock hook 5 is bent to form a U-shaped rod 401. The U-shaped rod 401 is arranged on the side of the lock hook 5 away from the unlocking button 3. When the unlocking button 3 is pressed, the torsion spring contracts. When the unlocking button 3 is released, the U-shaped rod 401 lifts the lock hook 5 upward.

[0041] In a preferred embodiment, Figure 6 As shown, a chamfer 10 is provided on one side of the locking end 502 away from the fixed end 501 . When the second connecting portion 203 is inserted into the corresponding stick body 9 , the chamfer 10 helps the locking end 502 to slide into the locking hole 7 .

[0042] Example 2

[0043] The difference between this embodiment and the first embodiment is that the self-locking member 1 and the end of the stick body 9 with the locking hole 7 are fixed not only by the locking end 502, but by the joint action of the locking end 502 and the second connecting portion 203. At this time, the cross section of the locking hole 7 is a U-shaped structure opening toward the mounting portion 201, that is, Figure 3 The locking hole 7 in the middle, the second connecting part 203 is provided with an external thread, which is threadedly connected to the end of the stick body 9 with the locking hole 7. The locking hook 5 is mainly used for circumferential limiting at this time. Since the second connecting part 203 and the stick body 9 are not normally connected and need to be disassembled frequently, thread wear may occur. The connection between the locking hook 5 and the locking hole 7 can prevent the second connecting part 203 and the stick body 9 from rotating relative to each other.

[0044] Example 3

[0045] On the basis of the above embodiment, the quick self-locking structure further includes a transition piece 11 connected to the locking end 502, such as Figure 3 and Figure 4 As shown, the adapter 11 includes a third connecting portion 1101 and a locking portion 1102. The locking hole 7 is located in the locking portion 1102, and the second connecting portion 203 is located in the locking portion 1102. The third connecting portion 1101 is provided with an external thread. In this case, only an internal thread needs to be provided at the end of the stick body 9, and no hole needs to be drilled.

[0046] When two stick bodies 9 need to be connected, the first connecting part 202 of the self-locking part 1 is fixed to one of the stick bodies 9, and the third connecting part 1101 of the adapter 11 is fixed to the other stick body 9. The locking hook 5 is hooked on the locking hole 7 of the adapter 11. The second connecting part 203 is inserted into the inside of the adapter 11 at this time. The self-locking part 1 and the adapter 11 can be normally connected to the stick body 9 respectively. The frequently disassembled parts are located on the self-locking part 1 and the adapter 11. Therefore, the self-locking part 1 and the adapter 11 become wearing parts. Compared with the stick body 9, the replacement cost of the self-locking part 1 and the adapter 11 is lower.

[0047] Example 4

[0048] A long baton includes one or more baton bodies 9 and the quick self-locking structure described in Examples 1 and 2. The first connecting portion 202 and the second connecting portion 203 of the quick self-locking structure respectively connect two adjacent baton bodies 9. For example, the self-locking member 1 can be uniformly installed at the right end of the baton body 9, and the locking hole 7 is provided at the left end of the baton body 9, and then multiple baton bodies 9 are sequentially connected.

[0049] In a preferred embodiment, a multifunctional connecting terminal 12 can be installed at the end of the long baton. The end of the multifunctional connecting terminal 12 has a card slot or an inner screw thread, which can be used to fix warning lights, rescue equipment, capture devices and other equipment. The multifunctional connecting terminal 12 is connected to the self-locking part 1 on the stick body 9. In this case, a locking hole 7 (such as Figure 6 shown).

[0050] Example 5

[0051] A long baton comprises one or more baton bodies 9 and the quick self-locking structure described in the third embodiment, wherein the first connecting portion 202 and the third connecting portion 1101 of the quick self-locking structure respectively connect two adjacent baton bodies 9.

[0052] During installation, as described in the third embodiment, the self-locking member 1 and the adapter 11 are respectively installed on the two stick bodies 9 to be connected.

[0053] Example 6

[0054] On the basis of Example 5, the two ends of each stick body 9 are respectively connected with a self-locking part 1 and an adapter 11, and the stick body 9 at the end of the long baton is connected with a window breaking end 13 and / or a multifunctional connecting end 12.

[0055] like Figure 1 and Figure 2 As shown, the self-locking member 1 and the adapter 11 can be normally installed at both ends of the stick body 9 to form a stick assembly 14 that can be quickly connected. Multiple stick assemblies 14 can be connected in sequence. The stick assembly 14 can also be connected to the multi-functional connecting end 12 or the window breaking end 13, as shown in FIG. Figure 5 As described, the window breaking end head 13 is connected to the adapter 11 in the stick assembly 14 , and the end of the window breaking end head 13 has a protrusion, which can be used for breaking windows.
