Description

Technical Field

[0001] This utility model relates to the field of police equipment technology, and in particular to a telescopic blast-proof baton. Background Technology

[0002] In the practical application of law enforcement equipment, telescopic batons serve as an important protective and control tool for law enforcement personnel. Their structural stability is directly related to the smooth conduct of law enforcement tasks and the personal safety of law enforcement personnel. The widely used 2018 basic telescopic baton has several issues. When the hardness of the narrow damping ring is insufficient and its fit with the outer wall of the tube is inadequate, it cannot form a uniform damping force. When the hardness of the damping ring is too high, the friction with the outer wall of the tube is too great, requiring a greater external force to extend the tube, making it difficult to quickly swing out in an emergency. When the hardness of the damping ring is too low, the damping effect is insufficient, and the tube is prone to slight retraction after extension, failing to maintain a stable locked state. Furthermore, the O-ring of the tube, as an auxiliary sealing and buffering component, has a poor cross-sectional dimension that does not match the groove of the outer wall of the tube. It is prone to displacement or deformation during sliding, not only losing its proper buffering effect but also generating additional resistance due to the irregular compression of the O-ring, exacerbating the jamming sensation during tube sliding. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a telescopic explosion-proof baton that can solve the following problems: when the hardness of the narrow damping ring is insufficient and its fit with the outer wall of the tube is inadequate, it cannot form a uniform damping force; when the hardness of the damping ring is too high, the friction between it and the outer wall of the tube is too large, resulting in a greater external force required when the tube extends, making it difficult to swing out quickly in an emergency; when the hardness of the damping ring is too low, the damping effect is insufficient, and the tube is prone to slight retraction after extension, making it unable to maintain a stable locked state. Furthermore, the O-ring of the tube, as an auxiliary sealing and buffering component, has a poor cross-sectional dimension that does not match the groove of the outer wall of the tube, making it prone to displacement or deformation during sliding. This not only loses its proper buffering effect, but also generates additional resistance due to the irregular compression of the O-ring, exacerbating the problem of the tube sliding with a stuck feeling.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a telescopic explosion-proof baton, comprising a handle, a switch assembly, a middle tube assembly, and a small tube assembly. The switch assembly is located on one side of the handle, and the middle tube assembly is located inside the handle. The middle tube assembly includes a middle tube, a middle tube outer wall retaining ring, a middle tube narrow damping ring, a middle tube O-ring, a middle tube end wide damper, and a metal drum. The middle tube is slidably connected inside the handle. The outer surface of the middle tube is provided with a middle tube outer wall retaining ring. A middle tube narrow damping ring is provided on one side of the middle tube outer wall retaining ring. A middle tube O-ring is provided on one side of the middle tube narrow damping ring. A middle tube end wide damper is provided on one side of the middle tube O-ring.

[0005] The small tube assembly is located inside the middle tube. The small tube assembly includes a roller head, a small tube outer wall retaining ring, a small tube narrow damping ring, a small tube O-ring, a small tube end wide damping ring, metal drum A and metal drum B. The roller head is slidably connected inside the middle tube. The outer surface of the roller head is provided with a small tube outer wall retaining ring. A small tube narrow damping ring is provided on one side of the small tube outer wall retaining ring. A small tube O-ring is provided on one side of the small tube narrow damping ring. A small tube end wide damping ring is provided on one side of the small tube O-ring.

[0006] Preferably, a metal drum disc A and a metal drum disc B are provided on one side of the wide damping ring at the end of the small tube, and the metal drum disc A and the metal drum disc B are symmetrically distributed.

[0007] Preferably, a grip rubber sleeve is fixedly fitted onto the outer surface of the grip, and the surface of the grip rubber sleeve is provided with fine granular anti-slip texture.

[0008] Preferably, the switch assembly includes a tail cover, an unlocking lever, and an unlocking button. The tail cover is fixedly connected to one side of the handle, and the unlocking lever and unlocking button are provided inside the tail cover.

[0009] Preferably, the switch assembly includes a tail cover, an unlocking lever, and an unlocking button. The tail cover is fixedly connected to one side of the handle, and the unlocking lever and unlocking button are provided inside the tail cover.

[0010] Preferably, the tail cap has a mounting groove for fixing the anti-detachment ring.

[0011] Preferably, the inner side of the narrow damping ring of the middle tube is provided with an arc-shaped fitting surface that is adapted to the outer wall of the middle tube, and the curvature of the fitting surface is consistent with the curvature of the outer wall of the middle tube.

[0014] Preferably, the O-ring of the small tube has an elliptical cross-section, and its major axis is aligned with the sliding direction of the small tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This telescopic blast-proof baton features a narrow damping ring in the central tube with an arc-shaped contact surface that matches the curvature of the outer wall of the central tube. This significantly improves the fit between the ring and the outer wall. Combined with optimized hardness selection, it avoids uneven damping force caused by insufficient contact between the ring and the outer wall of the central tube. When the hardness of the damping ring matches the fit, it avoids excessive friction caused by excessive hardness, allowing for rapid deployment in emergencies without the need for additional external force. It also prevents insufficient damping effect caused by insufficient hardness. After the central tube extends, there is no slight retraction, maintaining a stable locked state. This ensures that law enforcement officers can quickly deploy the baton in emergency scenarios and effectively perform protective and control tasks by relying on the stable locking structure.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Example 1: Lightweight police baton for urban patrol (7075-T6 aluminum alloy baton body)

[0026] Applicable scenarios: Urban police officers conduct daily street patrols and control densely populated areas, requiring batons that are lightweight, portable, and strong enough to handle general conflicts.

[0027] Material application: The baton body (main structure such as the middle tube 2 and the baton head 1) is made of 7075-T6 aluminum alloy. Utilizing its high strength and low density characteristics, the overall weight of the baton is reduced by about 20% compared to conventional materials. The weight of a single baton is controlled within 500g, so that the police officers do not feel burdened when holding it for a long time.

[0028] Structural fit: The excellent processing performance of 7075-T6 aluminum alloy allows for precise forming of fine structures such as the narrow damping ring 12 in the middle tube and the narrow damping ring 6 in the small tube, ensuring smooth sliding of the middle tube 2 within the handle 3 and the baton head 1 within the middle tube 2. At the same time, the material strength ensures the stable positioning of components such as the outer wall retaining ring 11 of the middle tube and the outer wall retaining ring 5 of the small tube for the damping ring and O-ring, and reliable telescopic locking. In case of emergencies during patrol, the baton can be quickly unlocked and extended. The aluminum alloy baton body is impact-resistant and can effectively stop the actions of lawbreakers. Its lightweight nature also allows for flexible swinging to control the situation.

[0029] Example 2: Police baton for duty in humid environments (GuAl8 aluminum bronze baton body)

[0030] Applicable scenarios: Police batons are required to have excellent corrosion resistance and rust prevention properties in rainy areas in the south, law enforcement on water, and damp underground spaces.

[0031] Material Application: The baton body (two middle tubes, one baton head, etc.) is made of GuAl8 aluminum bronze. Taking advantage of its excellent corrosion resistance due to the presence of aluminum, nickel and other elements, it can effectively resist moisture and humidity erosion in humid and watery environments, avoiding the structural damage caused by rust and corrosion that is common in ordinary metal materials.

[0032] Structural fit: The mechanical properties of GuAl8 aluminum bronze are compatible with the installation dimensional accuracy of components such as the outer wall retaining ring 11 of the middle tube and the outer wall retaining ring 5 of the small tube. The narrow damping ring 12 of the middle tube and the narrow damping ring 6 of the small tube fit tightly with the surface of the aluminum bronze baton, and the sliding damping is stable. Even when on duty in humid environments such as docks and underground garages for a long time, the extension and retraction function of the baton is not affected by corrosion. In case of emergency, it can be unlocked and extended smoothly, reliably stopping illegal and criminal acts. Moreover, its service life is more than 3 times longer than that of conventional materials in humid environments.

[0033] Example 3: Multi-environment universal baton (combination of 7075-T6 aluminum alloy and GuAl8 aluminum bronze)

[0034] Applicable scenarios: Scenarios where duty shifts frequently between different environments (city streets, humid areas, mountainous areas, etc.) are required, where batons need to be lightweight, corrosion-resistant, and strong.

[0035] Material Application: The baton is made of 7075-T6 aluminum alloy for components such as the central tube 2 and the handle 3, which are not directly impacted and are sensitive to weight. Taking advantage of its lightweight and high strength, the baton head 1 and the wide damper 14 at the end of the central tube, which are prone to impact and exposure to humid environments, are made of GuAl8 aluminum bronze to give full play to its corrosion resistance and high impact resistance. The two materials are combined into a baton through a reliable connection structure (such as metal drum discs and other components to achieve force connection and transmission).

[0036] Structural fit: The different physical properties of 7075-T6 aluminum alloy and GuAl8 aluminum bronze, with the adaptation of structures such as the narrow damping ring 12 of the middle tube and the narrow damping ring 6 of the small tube, still ensure smooth extension and stable locking of the middle tube 2 within the handle 3 and the baton head 1 within the middle tube 2. When on duty, whether quickly handling disputes in dry city streets or facing complex situations in damp mountainous areas or underground spaces, the baton can work stably and reliably, balancing portability and durability, reducing the trouble for law enforcement officers to change equipment due to changes in environment.

[0037] Furthermore, when using this device, the baton is swung, causing the middle tube assembly and the small tube assembly to extend axially under inertial force. The middle tube 2 slides outward relative to the handle 3 under inertial force. The retaining ring 11 on the outer wall of the middle tube moves synchronously with the middle tube 2 until it contacts the end of the handle 3, limiting the maximum extension position of the middle tube 2. During the sliding process, the narrow damping ring 12 of the middle tube makes close contact with the inner wall of the handle 3 through its arc-shaped contact surface, providing uniform damping force. This ensures that the middle tube 2 can be swung out quickly while avoiding excessive impact due to excessive sliding speed. The O-ring 13 of the middle tube slides with the middle tube 2 within the groove. Through its adapted cross-sectional dimensions and fit with the groove, it reduces offset and deformation, minimizing the feeling of jamming. The wide damper 14 at the end of the middle tube cooperates with the metal drum 15 to further enhance the damping effect, ensuring stable locking after the middle tube 2 is fully extended. Simultaneously, the baton head 1 slides outward relative to the middle tube 2 under inertial force, and the small tube... The outer wall retaining ring 5 moves synchronously with the baton head 1 until it contacts the end of the middle tube 2, limiting the maximum extension position of the baton head 1. Then, the annular protrusion of the narrow damping ring 6 of the small tube rubs against the inner wall of the middle tube 2, providing damping force. The O-ring 7 of the small tube reduces sliding resistance through the adaptive deformation of its elliptical cross-section. The wide damping ring 8 at the end of the small tube cooperates with the metal drum discs A9 and B10 to enhance locking stability, ultimately allowing the baton head 1 to fully extend and lock. Then, when it is necessary to retract the baton, press the unlock button on the tail cap 4. The unlock button drives the unlocking lever to release the locking mechanism between the middle tube 2 and the handle 3, and between the baton head 1 and the middle tube 2. Then, manually push the baton head 1 towards the handle 3. The baton head 1 slides inward relative to the middle tube 2. The narrow damping ring 6 of the small tube, the O-ring 7 of the small tube, and the wide damping ring 8 at the end of the small tube retract with the baton head 1. The metal drum discs A9 and B10 assist in the reset of the damping rings.

[0038] Next, continue to push the middle tube 2. The middle tube 2 slides inward relative to the handle 3. The narrow damping ring 12, the middle tube O-ring 13, and the wide damper 14 at the end of the middle tube retract with the middle tube 2. The metal drum 15 assists in the damper's reset. Finally, the middle tube 2 is completely retracted into the handle 3, and the stick head 1 is completely retracted into the middle tube 2, completing the retraction.

[0039] The narrow damping ring 12 of the central tube adopts an arc-shaped contact surface design that matches the curvature of the outer wall of the central tube 2, which greatly improves the fit with the outer wall of the central tube. With the optimized hardness selection, the problem of uneven damping force caused by insufficient fit of the damping ring to the outer wall of the central tube is avoided. When the hardness of the damping ring matches the fit, it can avoid excessive friction caused by excessive hardness (it can be quickly thrown out in an emergency without the need to apply additional external force), and it can also prevent insufficient damping effect caused by insufficient hardness (there is no slight retraction after the central tube 2 is extended, and it can maintain a stable locked state). This ensures that law enforcement officers can quickly deploy batons in emergency scenarios and effectively perform protection and control tasks by relying on the stable locked structure.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
