Description

Technical Field

[0001] This invention relates to the field of clamping loading equipment technology, and in particular to a loading sleeve with an automatic locking structure. Background Technology

[0002] Existing clamping loaders work by having the loader's base support the weight of the object being loaded, and then using metal clamps with rubber rollers to clamp the object in place. Types of loaders currently include telescopic baton covers, spray covers, and flashlight covers.

[0003] However, simple caliper-type clamping loaders are not anti-theft. To achieve anti-theft, a "U-shaped" zinc alloy component with a certain degree of deformation resistance is usually added to both sides of the caliper. This component can rotate up and down around the axis. The "U-shaped" zinc alloy component has two fixed positions: tilting it upwards and parallel to the caliper indicates the open state, while tilting it downwards and perpendicular to the caliper indicates the closed state.

[0004] When using this type of telescopic baton cover, the baton is first inserted into the loading device (the metal calipers with rubber rollers automatically engage the baton), and then the "U-shaped" zinc alloy component is manually flipped upwards to open. At this point, prying the baton outwards will prevent the spring calipers from opening due to the "U-shaped" zinc alloy component on the outside, thus preventing the baton from being removed and achieving anti-theft protection. The strength of the anti-theft force depends on the deformation resistance of the "U-shaped" zinc alloy component. We consider this "U-shaped" zinc alloy component as the safety structure of the telescopic baton cover.

[0005] The disadvantages of the above technology are: Disadvantage 1. The safety mechanism cannot lock automatically. Taking the telescopic baton sleeve as an example, when the telescopic baton is inserted, the "U-shaped" zinc alloy part must be manually flipped up to lock the safety mechanism.

[0006] Disadvantage 2. Exposed safety mechanism, resulting in poor security. The "U-shaped" zinc alloy parts are exposed on both sides of the caliper, making them easily visible to robbers who can easily flip down the safety mechanism and seize the telescopic baton.

[0007] Disadvantage 3. Overall weight is relatively large. Due to strength requirements, each "U-shaped" zinc alloy component typically weighs over 15g. When multiple similar loaders are suspended on the belt, the weight is cumulative. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a loading sleeve with an automatic locking structure. It employs a built-in limiting structure to restrict the opening and closing state of the calipers, making it more convenient to use and providing higher safety.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a loading sleeve with an automatic locking structure, comprising a housing and a mounting plate disposed within the housing, wherein the upper two sides of the mounting plate are provided with claws capable of lever rotation, characterized in that a lateral triggering device is provided on the mounting plate, the lateral triggering device being linked with a safety button disposed at the rear of the mounting plate, the safety button forming a limiting module on both sides, the lateral triggering device driving the safety button to move and change the position of the limiting module, the limiting module pressing against one end of the lever to form a safety.

[0010] Preferably, the lateral triggering device has a first reset spring on its rear side, and the triggering device and the safety button are at a 90° angle. The triggering device can apply the force it receives to the safety button, so that the safety button receives a downward pressure.

[0011] Preferably, the horizontal triggering device includes a horizontally arranged trigger button, which is connected to an actuating button via a pin. A first inclined surface is formed on the actuating button, and a second inclined surface that matches the first inclined surface is formed on the safety button.

[0012] Preferably, the bottom of the safety button is provided with a set of press-to-lock / unlock structural grooves and a spring hook, and a second reset spring is provided vertically on both sides of the safety button.

[0013] Preferably, the bottom side of the safety button is provided with a horizontal locking groove, which is matched with a movable lock cylinder. The movable lock cylinder is exposed outside the outer shell and can be moved left and right.

[0014] Preferably, the upper middle part of the safety button has a hollow section, which is divided into two parts, wider at the top and narrower at the bottom. The narrower part has steps on both sides that form the second slope.

[0015] Preferably, the safety button has slots on both sides, and the limiting module is formed in the upper middle part of the slots.

[0016] Preferably, the mounting plate is provided with a metal base, and the two sides of the metal base are connected to injection molded claws by metal pins. A metal clamp is provided between the injection molded claws and the metal base, and a rubber roller is provided at the outer end of the injection molded claws.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The safety mechanism automatically opens when the telescopic baton is inserted, requiring no additional manual operation.

[0018] 2. The safety mechanism is built-in and hidden. When the telescopic baton is inserted, the safety button cannot be seen from the outside, thus improving safety.

[0019] 3. The overall weight is light, and the heavier zinc alloy safety device has been eliminated, replaced by injection-molded claw pieces and injection-molded safety buttons.

[0020] 4. The automatic insurance activation mode can be manually turned off. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1 The loading sleeve shown includes a housing 1 and a mounting plate 6 disposed inside the housing. The upper two sides of the mounting plate 6 are provided with claws that can rotate like levers. A lateral triggering device 4 is provided on the mounting plate. The lateral triggering device is linked with a safety button 3 disposed at the rear of the mounting plate. The safety button forms a limit module 34 on both sides. The lateral triggering device drives the safety button to move and change the position of the limit module. The limit module 34 presses against one end of the lever to form a safety.

[0029] In one embodiment, a first reset spring 11 is provided on the rear side of the lateral triggering device. The triggering device and the safety button are at a 90° angle. The triggering device can apply the force it receives to the safety button, so that the safety button receives a downward pressure.

[0030] In one embodiment, the horizontal triggering device includes a horizontally positioned trigger button 8, which is connected to an actuating button 12 via a pin. The actuating button 12 has a first inclined surface 13, and the safety button 3 has a second inclined surface 35 that matches the first inclined surface. During actual operation, when the trigger button is subjected to force, the first inclined surface of the actuating button exerts force on the second inclined surface of the safety button, causing the safety button to move downwards. Under the action of a first spring force, the trigger button pops out, driving the actuating button to move. After encountering resistance from the stepped surface of the safety button, i.e., the second inclined surface, the actuating button flips backwards and disengages. Finally, under the continued action of the spring force, it returns to its pre-trigger working state.

[0031] In one embodiment, the bottom of the safety button is provided with a set of press-to-lock / unlock structural grooves 36 and a spring hook 39, and second reset springs are vertically arranged on both sides of the safety button 3. The working principle is similar to that of a mechanical pencil. When the safety button is pressed down, the safety button assembly is hooked by the spring hook; when the safety button is pressed again, the spring hook is released, and the safety button resets to its initial state.

[0032] In one embodiment, a horizontal locking groove 37 is provided on the bottom side of the safety button, which is matched with a movable lock cylinder 40. The movable lock cylinder is exposed outside the outer casing 1 and can be moved left and right. When the safety button is pressed to its lowest position and the lock button is moved horizontally, the lock cylinder will fall into the uppermost spring hook locking groove 38 and lock the safety button. When the safety button is locked, the telescopic baton is placed inside the sleeve. The safety will not automatically open, but the telescopic baton can still be held by the caliper. However, even if the safety button is locked, as long as the telescopic baton is inside the sleeve, the safety button can pop out and reset the moment the lock button is closed. This achieves the open state of the safety and realizes the purpose of anti-robbery.

[0033] If the safety button is locked and no telescopic baton is inside the sleeve, closing the button will cause it to pop out and reset instantly. At this point, the calipers will be unable to open, preventing the insertion of the telescopic baton. The telescopic baton can only be inserted after the safety button is pressed and engaged by the internal spring hook. Once the telescopic baton is inserted, the safety button will immediately reset to the open position.

[0034] Specifically, there is a hollow section in the middle of the upper part of the safety button. The hollow section is divided into two parts: upper hollow 31 and lower hollow 32. The upper part is wider than the lower part, and the steps on both sides of the narrower part form the second slope mentioned above.

[0035] Specifically, slots 33 are formed on both sides of the safety button, and the limiting module 34 is formed in the upper middle part of the slots.

[0036] A metal base 7 is provided on the mounting plate. The two sides of the metal base are connected to injection molding claws 2 by metal pins 10. A metal clamp 9 is provided between the injection molding claws and the metal base. A rubber roller 5 is provided at the outer end of the injection molding claws.

[0037] The working principle of this invention is as follows: When the telescopic baton is not inserted, the safety button is in the reset state (i.e., the initial state). When the telescopic baton is inserted, the outer wall of the baton presses against the trigger button. The trigger button applies force to the safety button through the first inclined surface on the actuation button. After being subjected to force, the safety button moves downward, the spring hook is released, and the safety button pops upward.

[0038] After the safety button pops out, the limiting modules on both sides of its structure press against one end of the rotating lever of the injection-molded claw piece, preventing the lever from rotating. Therefore, the telescopic rod cannot be removed while the safety is engaged. This achieves the automatic safety engagement process.

[0039] In addition, the telescopic baton sleeve with this structure can be opened or closed manually by pressing the safety button, regardless of whether the telescopic baton is inserted (when open, the safety button pops out at a high position; when closed, the safety button is compressed at a low position), and the open and closed states are a cyclic process.

[0040] The product of this invention is lighter overall, easier to use, and safer. It is applicable to a wider range of scenarios and can be adapted to different needs. It can also be extended to cylindrical equipment, such as commonly used flashlights, sprayers, traffic batons, and other standardized equipment with relatively fixed diameters.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
