Description

Technical Field

[0001] This utility model relates to the field of restraint technology, and in particular to a hand and leg controller. Background Technology

[0002] Existing handcuffs or leg irons consist of two connected bodies. Each body comprises a fixed ring and a movable ring forming a closed loop. The first end of the fixed ring of one body is fixedly connected to the first end of the fixed ring of the other body. The first end of the movable ring is hinged to the second end of the fixed ring via a pin. The second end of the movable ring and the first end of the fixed ring have a locking mechanism. When used by law enforcement officers, the locking mechanism must be released, separating the second end of the movable ring from the second end of the fixed ring. The movable ring can then rotate around the second end of the fixed ring via the pin, creating a notch in the handcuff body for the officer's wrist or ankle to insert into the fixed ring. The second end of the movable ring then locks back into the second end of the fixed ring, thus achieving restraint and control of the offender. However, handcuffs or leg irons of this type cannot be disassembled for individual use. This means that handcuffs or leg irons are only used to restrain the hands or feet of illegal persons after they have been successfully subdued. This forces law enforcement officers to use a multi-person encirclement method to arrest illegal persons, which is less than ideal. Even when handcuffs are used in conjunction with the arrest, the opening of the handcuffs is limited to the space where the movable ring opens, making it difficult to quickly subdue the wrists of illegal persons.

[0003] In view of this, the inventor of this invention came into being to assist law enforcement officers in the arrest of illegal individuals. Utility Model Content

[0004] The purpose of this utility model is to provide a hand and foot controller that can assist law enforcement officers in making arrests, is easy to operate, and allows illegal individuals to easily insert their wrists into uniforms.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hand and leg controller, comprising a grasping body and a restraining body. The restraining body has a first buckle and a second buckle with a non-closed-loop structure. The first buckle and the second buckle are arranged laterally opposite to each other to form a closed-loop space. The first end of the first buckle and the first end of the second buckle are movably hinged to the grasping body in such a way that the first buckle and the second buckle can rotate towards each other to form a closed-loop space and can rotate away from each other to separate to form an open-loop space. The first end of the first buckle and the first end of the second buckle are closely adjacent to each other and form an installation gap. The grasping body is provided with an operating rod whose first end is within the installation gap and whose second end extends away from the closed-loop space. The operating rod can be moved along the operating rod. The control lever is installed on the gripper body by translating axially and extending into a closed-loop space, with a portion of the control lever exposed outside the gripper body. The first end of the control lever, the first end of the first buckle, and the first end of the second buckle are provided with a rotation drive structure that drives the first buckle and the second buckle to rotate synchronously in opposite directions or in opposite directions as the control lever is translated. The second end of the first buckle and the second end of the second buckle have a plug-in structure that engages with the first buckle and the second buckle as they rotate in opposite directions and separates when they rotate in opposite directions. The gripper body is equipped with a restriction structure that automatically restricts the rotation of the first buckle or the second buckle after they rotate in opposite directions and manually releases the restriction on the first buckle or the second buckle before they rotate in opposite directions.

[0006] The second end of the first buckle is recessed with a receiving groove, and the second end of the second buckle extends with an extension portion that can be inserted into the receiving groove. The receiving groove and the extension portion constitute the aforementioned plug-in structure.

[0008] The connecting rod has an enlarged diameter section that clamps between the front and rear fasteners and a sleeve mounting section at both ends of the enlarged diameter section that passes through the front and rear fasteners respectively. The extension portion is close to and fits with the enlarged diameter section.

[0009] The aforementioned gripping body has a gripping part and a mounting part. The mounting part is located on the top surface of the gripping part. The lower ends of the first buckle and the second buckle are both located inside the mounting part. The left pin and the right pin are located inside the mounting part. The gripping part has an exposed space. The operating rod is vertically installed. The upper end of the operating rod is located inside the mounting part, and the lower end of the operating rod extends downward through the mounting part into the exposed space.

[0010] The lower ends of the aforementioned front buckle and rear buckle both have downward-protruding left convex arc blocks, and the lower end of the aforementioned second buckle has a downward-protruding right convex arc block. The aforementioned left and right convex arc blocks are arranged at intervals relative to each other, and the distance between the left and right convex arc blocks is the aforementioned installation distance. The right side and bottom surface of the aforementioned left convex arc block are provided with a number of continuously engaging right teeth, and the left side and bottom surface of the aforementioned right convex arc block are provided with a number of continuously engaging left teeth. The upper end of the aforementioned operating rod is located between the left and right convex arc blocks, and the left and right side walls of the operating rod are provided with tooth rows that mesh with both the left and right teeth. The tooth rows, each left tooth, and each right tooth constitute the aforementioned rotation drive structure.

[0011] The aforementioned operating lever is a square rod with an upper narrowing section and a lower widening section. The upper narrowing section has toothed teeth on both sides. The upper part of the upper narrowing section is inside the mounting part, and the lower part is above the exposed space. The lower part of the lower widening section extends downward into the exposed space. A gripping rod is installed in the exposed space, which is horizontally arranged in the left-right direction and perpendicular to the lower widening section. The left and right ends of the gripping rod extend into the gripping part. The left and right side walls of the exposed space are provided with strip grooves for the gripping rod to move up and down. The lower widening section is installed together with the gripping rod, and the lower widening section and the gripping part are provided with a restoring force generating device that generates an upward elastic restoring force as the gripping rod moves downward.

[0012] The aforementioned lower expansion section has a hollow structure and an open bottom surface. A vertically installed spring is installed inside the lower expansion section. The aforementioned gripping part is located in the exposed space and has a vertically installed top holding rod with its upper end extending into the lower expansion section. The aforementioned spring is stacked on the top holding rod. The top holding rod and the spring constitute the restoring force generating device.

[0013] The right side of the aforementioned left convex arc block, located above the right tooth, is inclined to the left, and the left side of the aforementioned right convex arc block, located above the left tooth, is inclined to the right. The left and right inclined surfaces form a flared mouth that gradually narrows from top to bottom. The upper end of the aforementioned upper narrowing section is provided with a limiting head that matches the flared mouth.

[0014] The grasping body has a movable block that can move up and down located below the left or right convex arc block. The front and rear sides of the movable block extend out of the grasping body respectively. The top surface of the movable block has an upwardly protruding limiting tooth. An elastic element that generates elastic restoring force as the movable block moves down is installed in the grasping body. The elastic element is connected to the movable block, and the movable block and the elastic element constitute the limiting structure.

[0015] By adopting the above technical solution, this utility model provides a hand and leg controller. When law enforcement officers subdue an illegal person at close range, they grasp the gripping body, and the first and second buckles open, directly inserting the illegal person's wrist into the restraint space. Then, the operating lever is moved. The movement of the operating lever uses a rotation drive structure to make the first and second buckles rotate in opposite directions, and a plug-in structure forms a closed loop space, thus restraining the illegal person's hand. At the same time, a limiting structure makes the closed loop space formed by the first and second buckles a fixed space. In this way, when the illegal person's hand is restrained and rotated during the subjugation process, it will cause pain, thereby reducing the illegal person's ability to resist, and thus effectively assisting law enforcement officers in the arrest. Moreover, the entire operation only requires the operation lever to be moved horizontally, which is simple to operate and has a simple structure. When the illegal person's wrist is inserted, the first and second buckles are in a state of opposite directions and open simultaneously, with a large opening, which is not easily restricted by wrists of different sizes. It has a wide range of applications, is easy to use, and allows the illegal person's wrist to easily enter the restraint. Attached Figure Description

[0021] This utility model provides a hand and leg controller, such as... Figure 1-4As shown, it includes a grasping body 1 and a restraining body. Preferably, the grasping body 1 has a grasping part 11 and a mounting part 12. The mounting part 12 is located on the top surface of the grasping part 11. Preferably, the grasping part 11 is a square plate extending in the left and right direction. The left and right sides of the square plate transition to the top surface in an arc shape. The mounting part 12 is located in the middle part of the top surface of the square plate and has a square structure. The width of the mounting part 12 in the left and right direction is smaller than the width of the grasping part 11 in the left and right direction. To facilitate the assembly of the hand and foot controller, the gripper is assembled from two cover plates. The square plate is composed of a front plate and a rear plate. The rear side of the front plate is integrally formed with a rear side panel, and the front side of the rear plate is integrally formed with a front side panel. The front plate, rear plate, rear side panel, and front side panel form a hollow square space with an opening on the top surface. The mounting part 12 is located within the opening of the hollow square space, and the mounting part 12 has a front narrowing plate and a rear narrowing plate. The front narrowing plate is located at the middle of the top surface of the front plate and is integrally formed, and the rear narrowing plate is located at the middle of the top surface of the rear plate and is integrally formed. The front plate and the rear plate are locked together by fasteners.

[0022] The restraint body has a first buckle 2 and a second buckle 3 with a non-closed ring structure. The first buckle 2 and the second buckle 3 are arranged laterally opposite to each other to form a closed ring space. The first end of the first buckle 2 and the first end of the second buckle 3 are movably hinged to the gripping body 1 in such a way that the first buckle and the second buckle can rotate towards each other to form a closed ring space and the first buckle and the second buckle can rotate away from each other to form an open ring space. The first end of the first buckle and the first end of the second buckle are closely adjacent to each other and form an installation gap. Preferably, the first buckle 2 has a front buckle piece 21 and a rear buckle piece 22 that are vertically arranged with a front buckle piece 21 and a rear buckle piece 22 that are arranged at a distance from each other. All clips 22 are concave arc-shaped pieces facing left, and are close to a semi-circular structure. The front clip 21 and the rear clip 22 are connected together by a connecting rod 23. This connecting rod 23 has an enlarged diameter section that clamps between the front clip and the rear clip, and two corresponding fitting sections that pass through the front clip and the rear clip at both ends of the enlarged diameter section. The fitting sections and the enlarged diameter section are both cylindrical rod structures. The front clip and the rear clip are installed by the two fitting sections passing through the front clip and the rear clip, and the enlarged diameter section keeps the distance between the front clip and the rear clip fixed. The lower ends of the front clip 21 and the rear clip 22 are both inside the mounting part 12, and the lower ends of the front clip 21 and the rear clip 22 are connected. The lower ends of the two rings 22 are hinged to the gripper body via a left pin 24. The left pin passes sequentially from front to back through the front reducing plate, the front buckle plate, the rear buckle plate, and the rear reducing plate. The front reducing plate and the front buckle plate are tightly fitted together, and the rear buckle plate and the rear reducing plate are also tightly fitted together. A clamping sleeve, fitted around the left pin, is located between the front and rear buckle plates. The engagement of the left pin and the clamping sleeve allows the front and rear buckle plates to rotate stably. The second retaining ring 3 is a vertically positioned, right-convex arc-shaped piece. Preferably, the front and rear buckle plates are of the same thickness as the arc-shaped piece, which is positioned between the front and rear buckle plates. The lower end of the second retaining ring 3 is located within the mounting section and is hinged to the gripper body via a right pin 31. In the mounting body, the front and rear ends of the right pin 31 are inserted into the front and rear reducing plates respectively to achieve hinged installation. The right pin 31 is fitted onto the tightening sleeves on the front and rear sides of the second retaining ring 3. The tightening sleeves prevent the second retaining ring from shaking during rotation. The lower end of the front retaining plate 21 has a downward-protruding left convex arc block 211, and the lower end of the rear retaining plate 22 has a downward-protruding left convex arc block 221. The lower end of the second retaining ring 3 has a downward-protruding right convex arc block 32. The left and right convex arc blocks are both nearly circular. The left and right convex arc blocks 32 are spaced apart from each other, and the distance between the left and right convex arc blocks is the installation distance.

[0023] The gripping body 1 is provided with an operating rod 4, the first end of which is within the installation distance and the second end of which extends away from the direction of the closed-loop space. The operating rod 4 is installed on the gripping body 1 in such a way that it can be translated along the axial direction of the operating rod and can be inserted into the closed-loop space. A part of the operating rod 4 is exposed outside the gripping body 11, that is, the gripping part 11 has an exposed space. Preferably, the gripping part 11 has a hollow space 100 that matches the contour of the gripping part 11. This hollow space 100 is the exposed space. The upper end of the operating rod 4 is inside the installation part, and the lower end of the operating rod 4 extends downward through the installation part into the exposed space. That is, the operating rod 4 is a square rod. The operating rod 4 has an upper narrowing section and a lower widening section. The upper part of the upper narrowing section is inside the installation part and the lower part is above the exposed space. The lower part of the lower widening section extends downward into the exposed space.

[0024] The first end of the operating lever 4, the first end of the first buckle 2, and the first end of the second buckle 3 are all provided with a rotation drive structure that drives the first buckle 2 and the second buckle 3 to rotate synchronously in opposite directions or in opposite directions as the operating lever 4 moves. Preferably, the right side and the bottom surface of the two left convex arc blocks arranged in front and behind are provided with a number of continuously engaging right teeth, and the left side and the bottom surface of the right convex arc block 32 are provided with a number of continuously engaging left teeth 321. The upper end of the operating lever 4 is located between the left convex arc block and the right convex arc block, and the left and right side walls of the operating lever 4 are provided with tooth rows that mesh with both the left and right teeth. That is, the left front and rear sides of the upper diameter reduction section are provided with a number of teeth arranged continuously from top to bottom that mesh with the right teeth. The teeth on the front side and the teeth on the rear side are respectively formed by the tooth rows. The right side of the upper diameter reduction section is provided with a number of teeth arranged continuously from top to bottom that mesh with the left teeth. The teeth mesh with each other, and each tooth forms the tooth row that meshes with the left tooth. The tooth row, each left tooth, and each right tooth form the rotation drive structure. Initially, the right tooth on the upper right of the left convex arc block meshes with the tooth row on the left side of the operating rod, and the left tooth on the upper left of the right convex arc block meshes with the tooth row on the right side of the operating rod. During operation, by grasping the lower expansion section of the operating rod 4 at the exposed space 100, and then pushing the operating rod 4 upward, the upward movement of the operating rod 4 uses the meshing of the teeth to make the front buckle and the rear buckle rotate to the left synchronously, and the second buckle 3 rotates to the right synchronously. The first buckle 2 and the second buckle 3 separate and open in opposite directions, forming a restraining space with two semi-circular openings joined together, allowing the wrist of the unauthorized person to easily enter the restraining space. After entering, the operating rod 4 is pulled down, and the front buckle, the rear buckle, and the second buckle rotate synchronously in opposite directions, forming a closed restraining space.

[0025] The second end of the first buckle 2 and the second end of the second buckle 3 have a plug-in structure that allows them to engage when the first buckle 2 and the second buckle 3 rotate in opposite directions and to separate when they rotate in opposite directions. Specifically, the upper end of the second buckle 3 extends to the left with the aforementioned extension (not shown in the figure). This extension is close to and engages with the expanded diameter section of the connecting rod 23. The front buckle, the rear buckle, and the second buckle have the same thickness. The second buckle is located between the front buckle and the rear buckle. That is, a receiving gap is formed between the upper end of the front buckle 21 and the upper end of the rear buckle 22, into which the extension can extend. This receiving gap and the extension constitute the aforementioned plug-in structure. In application, when the second buckle 3 and the first buckle 2 rotate towards each other, the extension of the second buckle 3 can extend into the accommodating gap between the front buckle piece 21 and the rear buckle piece 22, so that the first buckle and the second buckle form a closed-loop binding space. At the same time, the extension of the extension can be made to contact the extension of the connecting rod 23, so that the operating lever is operated in place.

[0026] The gripping body 1 is equipped with a limiting structure that automatically restricts the rotation of the first buckle 2 when it rotates towards the second buckle 3, and manually releases the restriction on the first buckle 2 before it rotates away from the second buckle 3. Preferably, a movable block capable of vertical movement is provided inside the gripping body 1, located below the left or right convex arc block. The front and rear sides of the movable block extend out of the gripping body, and the top surface of the movable block has upward-convex limiting teeth. An elastic element is installed inside the gripping body, generating elastic restoring force as the movable block moves downward. The elastic element is connected to the movable block, and the movable block and the elastic element constitute the limiting structure. Specifically, the gripping body 1 contains a left movable block 5 located below the left convex arc block, which can move up and down. The left movable block 5 is an upright plate structure. The front and rear sides of the left movable block 5 extend out of the gripping body 1, respectively. That is, the front and rear tapered plates have corresponding slotted holes 200 at the locations of the left movable block 5, allowing the left movable block 5 to partially extend and extend in the vertical direction. The slotted holes 200 enable the left movable block 5 to move up and down. The top surface of the left movable block 5 has a left limiting tooth 51 that can extend into the right tooth below the leftmost right tooth on the bottom surface of the two left convex arc blocks. The gripping body 1 contains... Equipped with a left torsion spring 6, the gripping body 1 has a protruding mounting rod extending in the front-to-back direction. The left torsion spring 6 is sleeved on the mounting rod, and both arms of the left torsion spring 6 extend horizontally in the left-to-right direction and are spaced vertically. One arm (i.e., the upper arm) of the left torsion spring 6 moves through the left moving block 5, and the other arm (i.e., the lower arm) of the left torsion spring 6 is located below the left moving block 5. The left moving block, the left limiting tooth, and the left torsion spring constitute the aforementioned limiting structure. Before the first buckle 2 and the second buckle 3 separate, the left moving block 5 moves downward, the left limiting tooth 51 separates from the left convex arc block, and the first buckle 2 and the second buckle 3 rotate in opposite directions. Rotating 2 to the left causes the left side of the left convex arc block to rotate to the bottom surface. The left limiting tooth 51 of the left moving block abuts against the left side of the left convex arc block, and the left torsion spring 6 is compressed. When the first buckle 2 and the second buckle 3 turn towards each other and engage, as the first buckle 2 rotates to the right, the bottom surface of the left convex arc block returns to its original position, and the spring of the left torsion spring 6 returns to its original position, causing the left moving block 5 to move upward. The upward movement of the left moving block 5 causes the left limiting tooth 51 to re-insert into the right tooth of the leftmost side of the bottom surface of the left convex arc block, preventing the first buckle from rotating. Thus, after the first buckle and the second ring are engaged, they cannot be opened even if the operating lever is pulled, ensuring high safety. In this utility model, in order to facilitate the up and down movement of the left moving block 5, anti-slip teeth (not shown in the figure) are protruding on the outer wall of the left moving block 5 located outside the gripper 1.

[0027] In this utility model, such as Figure 5 As shown, the elastic element can also be provided with a columnar spring 9. In this way, a groove is recessed upward on the bottom surface of the left moving block 5, the columnar spring 9 is located in this groove, and the upper end of the columnar spring 9 rests on the top of the groove, while the lower end of the columnar spring 9 rests on the side wall. The same effect of the left torsion spring can be achieved by using this columnar spring 9. This method makes the whole structure and installation simpler.

[0028] This utility model discloses a hand and leg controller, which is an auxiliary tool for subduing illegal persons. When multiple law enforcement officers are subduing an illegal person, one officer can open the first and second buckles of the controller, inserting the illegal person's wrist into the first and second buckles. Then, pulling down the operating lever closes the first and second buckles, thus binding the illegal person's hand. This causes pain when the illegal person resists and tries to twist their hand during the subduing process, reducing their resistance and effectively assisting law enforcement officers in the arrest. Opening the controller involves moving the left-hand moving block down and pushing the operating lever up; pulling down the lever again locks the first and second buckles together. The entire operation is simple, and the first and second buckles are open simultaneously with opposite directions when the illegal person's wrist is inserted, creating a large opening that is not easily restricted by wrist sizes. It has a wide range of applications, is convenient to use, and allows the illegal person's wrist to easily be inserted into the controller. In this utility model, the first and second buckles can be opened and kept in reserve before use. When used in the process of subduing, they can be taken out and pulled to bind the wrists of illegal persons. They can also be opened temporarily and used according to one's own needs.

[0029] In this invention, a gripping rod 7 is installed horizontally in the left-right direction and perpendicular to the lower expansion section within the exposed space 100. The left and right ends of the gripping rod 7 extend into the gripping part. Strip-shaped grooves (not shown in the figure) are provided on the left and right side walls of the exposed space 100 for the gripping rod to move up and down. Specifically, a strip-shaped notch extending in the up-down direction is recessed on the opposite surfaces of the rear and front side walls. The gripping rod 7 is located within the strip-shaped notch. The lower expansion section is installed together with the gripping rod, meaning the gripping rod is a hollow rod with an open bottom. The lower expansion section tightly fits through the top surface of the gripping rod into its hollow space. Lugs protrude from the left and right outer side walls of the lower expansion section, fitting against the inner top surface of the gripping rod. These lugs are secured to the gripping rod 7 with screws. On the top surface of the gripping part, the lower expansion section and the gripping part are provided with a restoring force generating device that generates an upward elastic restoring force as the gripping rod moves downward; preferably, the lower expansion section is hollow and the bottom surface of the lower expansion section is open. A vertically installed spring 81 is installed inside the lower expansion section. The gripping part 12 is located in the exposed space 100 and is provided with a vertically installed top holding rod 82, the upper end of which extends into the lower expansion section. The lower end of the top holding rod 82 is internally screwed with a locking member that limits its head to outside the bottom surface of the gripping part 12. The locking member fixes the top holding rod 82 in a fixed state. The spring 81 is vertically stacked on the top holding rod 82 and tensioned between the top holding rod and the inner top surface of the lower expansion section. The top holding rod 82 and the spring 81 constitute the restoring force generating device. In application, the gripping rod 7 facilitates the up-and-down movement of the operating rod 4. When the first and second buckles are engaged, the spring 81 is in a compressed state. Thus, when the gripping rod 7 is pushed up, the spring 81 returns to its original state, which can push the operating rod 4 upward, making it easier to open the first and second buckles. When the gripping rod 7 is pulled down, the spring 81 is compressed, and the left limiting tooth 51 and the left tooth insertion limit keep the spring 81 in a compressed state at all times.

[0030] In this invention, the right side of the left convex arc block, located above the right tooth, is inclined to the left, and the left side of the right convex arc block 31, located above the left tooth, is inclined to the right. The left and right inclined surfaces form a flared mouth that gradually narrows from top to bottom. The upper end of the narrowing section is provided with a limiting head 41 that matches the flared mouth. That is, the limiting head is flared in shape. The cooperation between the limiting head 41 and the flared mouth ensures that the operating rod moving down will not disengage from the left and right teeth, thus ensuring the stability of use.

[0031] In this invention, the left moving block and the left torsion spring can also be located on the right side. That is, the gripper body has a right moving block that can move up and down below the right convex arc block. The front and rear sides of the right moving block extend out of the gripper body. The top surface of the right moving block is located below the left tooth on the far right side of the bottom surface of the right convex arc block and has a right limiting tooth that can extend into the left tooth. The gripper body is equipped with a right torsion spring. Both arms of the right torsion spring extend horizontally in the left and right direction and are spaced up and down. One arm of the right torsion spring moves through the right moving block, and the other arm of the right torsion spring is located below the right moving block. The right moving block, the right limiting tooth, and the right torsion spring constitute the aforementioned limiting structure.

[0032] In this utility model, the first buckle can also be a single buckle body. In this way, the upper end of the first buckle is recessed with a receiving groove, and the upper end of the second buckle extends with an extension that can be inserted into the receiving groove. The receiving groove and the extension also constitute the aforementioned plug-in structure.

[0033] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
