Description

Technical Field

[0001] This utility model relates to the field of capture device technology, and specifically to a police-use belt-type capture device. Background Technology

[0002] Police arresting devices, also known as riot forks, were specifically invented to stop violent behavior and are typically used to apprehend out-of-control dangerous individuals. Existing police arresting devices employ a structure with two clasping arms at the front of the handle that can close together. In use, the two arms are opened, the arresting device is extended towards the target through the handle, and then the arms are closed to make the arrest. However, to facilitate capturing the target, the radius of the arms is usually set relatively large, leaving a certain gap after the arms are closed. This allows the target to easily escape, thus affecting the success rate of the arrest.

[0003] Therefore, how to provide a police-grade belt-type arresting device and method to improve the arresting success rate has become an urgent technical problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a police belt-type capture device to improve the capture success rate of the capture device.

[0005] This utility model provides a police belt-type arresting device, comprising:

[0006] A handle;

[0007] A timing pulley seat is located at the front end of the handle;

[0008] Two slide rails are arranged parallel to each other on the left and right sides of the synchronous pulley seat, and a meshing groove is provided at the opposite position along the sliding direction;

[0009] Two racks are respectively disposed in one of the slide rails, with dimensions matching the slide rails, lengths longer than the slide rails, and teeth facing the meshing grooves;

[0010] A limiting rod, with its two ends respectively connected to the rear end of one of the aforementioned racks;

[0011] A contact rod is connected at both ends to the front end of the rack and extends a certain distance beyond the rack;

[0012] A transmission mechanism is mounted on the synchronous pulley seat and meshes with the rack;

[0013] Two arc-shaped grippers are connected to the transmission mechanism at their rear ends via a rotating shaft, forming a circle with two strip mounting grooves on the inner side.

[0014] A release device is located at the front end of one of the arc-shaped grippers;

[0015] Two strip locking components are provided inside the release device, respectively located in front of one of the strip mounting grooves, and are rotatably connected to the release device.

[0016] A tapered connector is fitted onto the outer wall of the front end of another arc-shaped gripper and matches the release device;

[0017] A magnetic cable tie positioner is located inside a tapered docking device. The magnetic cable tie positioner includes a dual-compartment positioner housing, a lever, two magnets, and two excitation blocks. The lever passes through the middle of the dual-compartment positioner housing and is connected to one of the excitation blocks at both ends. The two magnets are located inside the dual-compartment positioner housing and are respectively located at the top of one of the excitation blocks.

[0018] Two strips, longer than the sum of the arc lengths of the two arc-shaped grippers, pass sequentially through the strip locking member, the strip mounting groove of one of the arc-shaped grippers, the strip mounting groove of the other arc-shaped gripper, and the magnetic cable tie positioner.

[0019] Two springs, one end of which is connected to one of the aforementioned arc-shaped grippers, and the other end of which is connected to the synchronous pulley seat;

[0020] A buffer pad is wrapped around the contact rod.

[0021] Furthermore, the transmission mechanism includes:

[0022] Two circular gears are symmetrically arranged at the top of the synchronous gear seat, meshing with each other, and their middle parts are respectively connected to an arc-shaped gripper arm through a rotating shaft;

[0023] A sector gear is located at the bottom of the synchronous gear seat. One end of the sector gear has teeth that mesh with one of the racks, and the other end is coaxially connected to one of the circular gears.

[0024] Furthermore, the strip locking member includes:

[0025] A lock body has a through-hole that matches the strip and is rotatably connected to the release device via a pin;

[0026] An elastic locking tongue for locking the strip is provided in the lock hole, rotatably connected to the lock body, and extends outward to an unlocking part, which matches the arc-shaped gripper arm.

[0027] The advantages of this utility model are:

[0028] The system comprises a handle, a synchronous pulley seat, a slide rail, racks, a limit rod, a contact rod, a transmission mechanism, arc-shaped gripping arms, a release device, a strip locking component, a tapered connector, a magnetic cable tie positioner, strip feeding, and springs. The synchronous pulley seat, equipped with the slide rail and transmission mechanism, is located at the front end of the handle. The rear ends of the two arc-shaped gripping arms are each connected to the transmission mechanism via a rotating shaft, forming a circle. Two racks are each located within a slide rail, with their rear ends connected to a limit rod to prevent falling and their front ends connected to a contact rod, engaging with the transmission mechanism. The strip locking component is located at the front end of one arc-shaped gripping arm via a release device, while the tapered connector and magnetic cable tie positioner are located at the front end of the other arc-shaped gripping arm. The head of the strip feed passes sequentially through the strip locking component, the strip feeding groove of one arc-shaped gripping arm, the strip feeding groove of the other arc-shaped gripping arm, and the magnetic cable tie positioner. One end of each of the two springs is connected to an arc-shaped gripping arm. The other end is connected to the synchronous wheel seat. During capture, the contact rod presses against the target to move backward, and the two arc-shaped grab arms close in conjunction with the rack and pinion and the transmission mechanism. When closed, the head of the strip is inserted into the strip buckle located in the strip locking member, and penetrates into the strip mounting groove through the locking hole of the strip locking member. At this time, the elastic locking tongue of the strip locking member is locked on the strip pawl, restricting the strip from retracting. The hand handle is moved backward to disengage the contact rod from the target. The arc-shaped grab arms return to their original position under the elastic force of the spring. At this time, the strip disengages from the strip mounting groove. As the arc-shaped grab arms unfold, the strip locking member pulls the head of the strip outward continuously, making the strip continuously tighten to bind the target. That is, while the arc-shaped grab arms surround the target, the strip is simultaneously fastened. When the arc-shaped grab arms return to their original position, the strip is tightened by the strip locking member to restrict the movement of the target, thereby greatly improving the capture success rate of the capture device.

Detailed Implementation

[0042] The technical solution in this application embodiment has the following general idea: a strip mounting groove 82 for mounting the strip is provided on the inner side of the arc-shaped grab arm 8, and a strip locking member 9 is provided at the front end of one of the arc-shaped grab arms 8. While the arc-shaped grab arm 8 surrounds the target, the strip is simultaneously fastened (the head of the strip is inserted into the strip buckle located in the strip locking member 9, and penetrates into the strip mounting groove 82 through the locking hole 911 of the strip locking member 9). When the arc-shaped grab arm 8 is reset, the strip is tightened by the strip locking member 9 to restrict the movement of the target, thereby improving the capture success rate of the grabber 100.

[0043] Please refer to Figures 1 to 10 As shown, a preferred embodiment of the police belt-type arresting device 100 of this utility model includes:

[0044] A handle 1 is used to hold the police belt-type arresting device 100;

[0045] A synchronous pulley seat 2 is located at the front end of the handle 1 and is used to install the slide rail 3, the transmission mechanism 7 and the spring;

[0046] Two slide rails 3 are arranged parallel to each other on the left and right sides of the synchronous pulley seat 2, and a meshing groove 31 is provided at the opposite position along the sliding direction; the slide rails 3 are used for limiting the sliding of the rack 4; the meshing groove 31 is used for the meshing of the rack 4 and the sector gear 72.

[0047] Two racks 4 are respectively disposed in one of the slide rails 3, with dimensions matching the slide rails 3, lengths longer than the slide rails 3, and teeth facing the meshing groove 31, for transmission when the contact rod 6 is displaced;

[0048] A limiting rod 5 is connected at both ends to the rear end of a rack 4 to prevent the rack 4 from falling off the slide rail 3;

[0049] A contact rod 6 is connected at both ends to the front end of a rack 4 and extends a certain distance beyond the rack 4. It is used to abut against the target, restrict the target's range of motion, and link the arc-shaped grab arm 8 to close.

[0050] A transmission mechanism 7 is provided on the synchronous pulley seat 2 and meshes with the rack 4, used to convert the pressure on the contact rod 6 into the power to close the arc-shaped gripper arm 8;

[0051] Two arc-shaped gripping arms 8 are connected to the transmission mechanism 7 at their rear ends via a rotating shaft 81, forming a circle with two strip mounting grooves 82 on their inner sides; the arc-shaped gripping arms 8 are used to enclose and capture the target;

[0052] A release device 84 is provided at the front end of one of the arc-shaped grippers 8;

[0053] Two strip locking members 9 are provided in the release device 84, respectively located in front of one of the strip mounting grooves 82, and are rotatably connected to the release device 84 for tightening the strip.

[0054] A tapered connector 83 is fitted onto the outer wall of the front end of another arc-shaped gripper 8 and matches the release device 84;

[0055] A magnetic cable tie positioner 10 is disposed inside the conical connector 83. The magnetic cable tie positioner 10 includes a dual-compartment positioner housing 101, a lever 102, two magnets (not shown), and two excitation blocks 103. The lever 102 passes through the middle of the dual-compartment positioner housing 101, and its two ends are respectively connected to one of the excitation blocks 103. The two magnets are disposed inside the dual-compartment positioner housing 101 and are respectively located at the top of one of the excitation blocks 103. By pressing the excitation block 103, the current excitation channel can be selected to excite the corresponding cable tie (that is, the excitation block 103 is attracted by the magnet to make room for the cable tie to pass through). Unexcited channels are blocked by the excitation block.

[0056] Two strips (not shown) are longer than the sum of the arc lengths of the two arc-shaped grab arms 8. Their heads pass sequentially through the strip locking member 9, the strip mounting groove 82 of one of the arc-shaped grab arms 8, the strip mounting groove 82 of the other arc-shaped grab arm 8, and the magnetic cable tie positioner 10, for binding and capturing the target.

[0057] Two springs (not shown) are connected at one end to one of the arc-shaped gripping arms 8 and at the other end to the synchronous pulley seat 2, for resetting the arc-shaped gripping arms 8;

[0058] A buffer pad (not shown) is wrapped around the contact rod 6 to avoid hard contact with the target being captured.

[0059] The transmission mechanism 7 includes:

[0060] Two circular gears 71 are symmetrically arranged at the top of the synchronous gear seat 2 and mesh with each other. Their middle parts are respectively connected to an arc-shaped gripper arm 8 through a rotating shaft 81; that is, during the rotation of the circular gears 71, the arc-shaped gripper arm 8 rotates synchronously (opens and closes).

[0061] A sector gear 72 is located at the bottom of the synchronous gear seat 2. One end of the sector gear 72 with teeth meshes with one of the racks 4, and the other end is coaxially connected to one of the circular gears 71. That is, during the displacement of the rack 4, the sector gear 72 will rotate in conjunction with it, thereby driving the circular gear 71 to rotate.

[0062] The strip locking member 9 includes:

[0063] A lock body 91 has a locking hole 911 that matches the strip and is rotatably connected to the release device 84 by a pin 912; the locking hole 911 is for passing through the head of the strip.

[0064] An elastic locking tongue 92 for locking the strip is located inside the lock hole 911 and is rotatably connected to the lock body 91. An unlocking part 921 extends outward and matches the arc-shaped gripper arm 8. In specific implementation, the front end of the elastic locking tongue 92 is in a depressed state and has a cut surface to facilitate the insertion of the strip. After the strip is inserted, it can only move forward and cannot move backward because the elastic locking tongue 92 is stuck on the strip's pawl. When the elastic locking tongue 92 is pried up by the unlocking part 921 (so that the unlocking part 921 presses on the arc-shaped gripper arm 8 and the strip locking member 9 is rotated), the strip is unlocked, and the strip buckle can be removed from the strip locking member 9.

[0065] The working principle of this utility model includes the following steps:

[0066] Step S1: Pass the head of the strip through the strip locking member, the strip mounting groove of one arc-shaped gripper arm, the strip mounting groove of the other arc-shaped gripper arm, and the magnetic cable tie positioner in sequence, so that the strip buckle is located in the strip locking member, in order to install the strip.

[0067] Step S2: Hold the handle and extend the two open arc-shaped grab arms toward the target to press the target onto the contact rod. During the pressing process, the contact rod moves backward.

[0068] Step S3: During the displacement of the contact rod, the two arc-shaped grippers are closed in sequence through the rack, sector gear, circular gear and rotating shaft.

[0069] Step S4: When the arc-shaped gripper arm closes, the head of the strip is just inserted into the strip buckle located in the strip locking member, and goes deep into the strip mounting groove through the locking hole of the strip locking member. At this time, the elastic locking tongue of the strip locking member is stuck on the strip pawl, restricting the strip from retracting.

[0070] Step S5: Move the hand handle backward to disengage the contact rod from the target, and the arc-shaped gripper arm will return to its original position under the elastic force of the spring.

[0071] Step S6: During the resetting process of the arc-shaped grab arm, the strip detaches from the strip mounting groove, and as the arc-shaped grab arm unfolds, the strip locking component continuously pulls the head of the strip outward, causing the strip to tighten continuously to bind and capture the target.

[0072] Step S7: After the belt is secured, rotate the belt locking component to make the unlocking part abut against the arc-shaped grab arm, thereby raising the elastic locking tongue, causing the belt locking component to release the belt, and the belt to disengage from the police belt-type capture device, thus completing the capture of the target.

[0073] In summary, the advantages of this utility model are as follows:

[0074] The system comprises a handle, a synchronous pulley seat, a slide rail, racks, a limit rod, a contact rod, a transmission mechanism, arc-shaped gripping arms, a release device, a strip locking component, a tapered connector, a magnetic cable tie positioner, strip feeding, and springs. The synchronous pulley seat, equipped with the slide rail and transmission mechanism, is located at the front end of the handle. The rear ends of the two arc-shaped gripping arms are each connected to the transmission mechanism via a rotating shaft, forming a circle. Two racks are each located within a slide rail, with their rear ends connected to a limit rod to prevent falling and their front ends connected to a contact rod, engaging with the transmission mechanism. The strip locking component is located at the front end of one arc-shaped gripping arm via a release device, while the tapered connector and magnetic cable tie positioner are located at the front end of the other arc-shaped gripping arm. The head of the strip feed passes sequentially through the strip locking component, the strip feeding groove of one arc-shaped gripping arm, the strip feeding groove of the other arc-shaped gripping arm, and the magnetic cable tie positioner. One end of each of the two springs is connected to an arc-shaped gripping arm. The other end is connected to the synchronous wheel seat. During capture, the contact rod presses against the target to move backward, and the two arc-shaped grab arms close in conjunction with the rack and pinion and the transmission mechanism. When closed, the head of the strip is inserted into the strip buckle located in the strip locking member, and penetrates into the strip mounting groove through the locking hole of the strip locking member. At this time, the elastic locking tongue of the strip locking member is locked on the strip pawl, restricting the strip from retracting. The hand handle is moved backward to disengage the contact rod from the target. The arc-shaped grab arms return to their original position under the elastic force of the spring. At this time, the strip disengages from the strip mounting groove. As the arc-shaped grab arms unfold, the strip locking member pulls the head of the strip outward continuously, making the strip continuously tighten to bind the target. That is, while the arc-shaped grab arms surround the target, the strip is simultaneously fastened. When the arc-shaped grab arms return to their original position, the strip is tightened by the strip locking member to restrict the movement of the target, thereby greatly improving the capture success rate of the capture device.
