Description

Technical Field

[0001] The present application relates to the technical field of restraint devices, and more particularly to a restraint device for restraining the upper body. Background Art

[0002] Currently, security personnel generally use steel forks for defense. The steel fork includes a grip rod and a steel fork head. The grip rod is fixedly connected to the steel fork head. The steel fork head is arc-shaped. The security personnel hold the grip rod and direct the steel fork head towards the target person, which can separate the target person to a certain extent, thus ensuring the safety of the security personnel.

[0003] However, the steel fork in the related art has a single function. When an emergency occurs, the steel fork in the related art has less restriction on the target person and is difficult to restrain the movement of the target person. Utility Model Content

[0004] In order to facilitate restricting the movement of the target person, the present application provides a restraint device for restraining the upper body.

[0005] The present application provides a restraint device for restraining the upper body, adopting the following technical solution:

[0006] A restraint device for restraining the upper body includes a steel fork body and a constant force spring detachably installed at the head of the steel fork body. When the constant force spring is installed on the steel fork body, it is in a stretched state and extends in a direction perpendicular to the axis of the steel fork body. After the constant force spring is impacted and detached from the steel fork body, it is in a wound state.

[0007] By adopting the above technical solution, when an emergency occurs, the security personnel hold the steel fork body and make the constant force spring touch the upper body of the target person. The constant force spring is triggered and becomes wound, and the constant force spring is separated from the steel fork body. The constant force spring winds around the upper body of the target person, which can restrain the arms and torso of the target person, thereby restricting the movement of the target person. Moreover, since the steel fork body is separated from the constant force spring, the steel fork body does not lose its original function.

[0008] Optionally, the constant force spring is provided with two mounting points, and the constant force spring and the steel fork body are mounted at the mounting points; one of the mounting points is located at the middle of the constant force spring, and the other mounting point is located near the end of the constant force spring.

[0009] By adopting the above technical solution, when in use, the area between the two mounting points of the constant force spring touches the upper body of the target person. The area between the two mounting points divides the constant force spring into a long side and a short side, such that the time required for the long side and the short side of the constant force spring to complete winding is different. This enables the short side of the constant force spring to wind around the upper body of the target person first, and then the long side of the constant force spring winds around the outside of the short side of the constant force spring, allowing the constant force spring to wind orderly. If the area between the two mounting points is located in the middle of the constant force spring, it is likely to cause the two ends of the constant force spring to collide with each other during winding, thus making it inconvenient to use.

[0010] Optionally, the length of the constant force spring is 3 - 4 times the distance between the two mounting points.

[0011] Optionally, the length of the constant force spring is 1.6 - 1.8 m.

[0012] By adopting the above technical solution, with an appropriate length, the constant force spring can wind around the upper body of the target person several times, facilitating better restraint of the target person.

[0013] Optionally, the triggering force of the constant force spring is 3 - 4 kg.

[0014] By adopting the above technical solution, with a triggering force of 3 - 4 kg, the constant force spring can wind, reducing the situation of mis-triggering and enabling the constant force spring to wind in a timely manner.

[0015] Optionally, magnets are provided on both the head of the steel fork body and the constant force spring, and the constant force spring is mounted on the head of the steel fork body through the magnets.

[0016] By adopting the above technical solution, the magnet on the head of the steel fork body is attracted to the magnet on the constant force spring, enabling the constant force spring to be mounted on the head of the steel fork body and also facilitating the separation of the constant force spring from the head of the steel fork body.

[0017] Optionally, the steel fork body is an aluminum alloy steel pipe.

[0018] By adopting the above technical solution, the steel fork body has high hardness, which can enhance the strength of the steel fork body and also make the steel fork body relatively light and convenient to use.

[0019] Optionally, a protective sleeve is sleeved outside the constant force spring.

[0020] By adopting the above technical solution, the protective sleeve can protect the constant force spring, reducing damage to the constant force spring from the outside world, and the protective sleeve can also reduce the harm of the constant force spring to the target person, enabling legal restraint of the target person.

[0021] Optionally, a magic tape is connected to the protective cover, and the magic tapes are adhered after the constant force spring is wound.

[0022] By adopting the above technical solution, when the constant force spring is wound around the upper body of the target person, the magic tapes on the protective cover are adhered to each other, thereby temporarily fixing the constant force spring and making it difficult for the target person to break free. Due to the setting of the magic tape, it is also convenient for the security personnel to untie the wound constant force spring.

[0023] Optionally, an avoidance hole for avoiding the installation point is formed on the protective cover.

[0024] By adopting the above technical solution, the avoidance hole of the protective cover can avoid the installation point, thereby facilitating the connection between the constant force spring and the steel fork body at the installation point.

[0025] In summary, the present application includes at least one of the following beneficial effects:

[0026] 1. When an emergency occurs, the security personnel hold the steel fork body and make the constant force spring touch the upper body of the target person. The constant force spring is in a wound state under the triggering force, and the constant force spring is separated from the steel fork body. The constant force spring is wound around the upper body of the target person, which can bind the arms and torso of the target person, thereby restricting the movement of the target person. Moreover, since the steel fork body is separated from the constant force spring, the steel fork body does not lose its original use function;

[0027] 2. The area between the two installation points divides the constant force spring into a long side and a short side. When touching the target person in the area between the two installation points of the constant force spring, the short side of the constant force spring is first wound around the upper body of the target person, and then the long side of the constant force spring is wound outside the short side of the constant force spring, so that the constant force spring can be wound orderly;

[0028] 3. The protective cover can protect the constant force spring, reduce the damage of the constant force spring by the outside world, and the protective cover can reduce the harm of the constant force spring to the target person;

[0029] 4. When the constant force spring is wound around the upper body of the target person, the magic tapes on the protective cover are adhered to each other, thereby temporarily fixing the constant force spring and making it difficult for the target person to break free.

[0036] The following will Figures 1-5 Further elaborate on the present application in detail.

[0037] The embodiment of the present application provides a restraint device for restraining the upper body.

[0038] Referring to Figure 1 and Figure 2 , the restraint device for restraining the upper body includes a steel fork body 1 and a constant force spring 2. The steel fork body 1 is an aluminum alloy steel pipe, and the constant force spring 2 is detachably connected to the head of the steel fork body 1.

[0039] Referring to Figure 2 and Figure 3 , the head of the steel fork body 1 is arc-shaped. The head of the steel fork body 1 has two ends, and magnets 5 are fixedly connected to both ends of the head of the steel fork body 1. There are two installation points provided on the constant force spring 2, and magnets 5 are fixedly connected to both installation points. The two ends of the head of the steel fork body 1 correspond to the two installation points one by one. The magnets 5 at the head of the steel fork body 1 can be magnetically connected to the magnets 5 at the installation points, realizing the detachable connection between the constant force spring 2 and the head of the steel fork body 1.

[0040] Referring to Figure 2 , when the constant force spring 2 is detachably installed on the head of the steel fork body 1, the constant force spring 2 is in an extended state and extends in a direction perpendicular to the axis of the steel fork body 1. When the constant force spring 2 is straightened, the constant force spring 2 is in an extended state, and the constant force spring 2 forms an arched structure in the width direction, which can support the constant force spring 2 from bending. The triggering force of the constant force spring 2 is 3 - 4 kg, which can reduce the situation of mis-triggering. When the impact force received by the constant force spring 2 is greater than the triggering force, the constant force spring 2 can be wound.

[0041] In case of an emergency, the security personnel hold the steel fork body 1 to make the constant force spring 2 touch the upper body of the target person. The constant force spring 2 is in a wound state under the triggering force and separates from the steel fork body 1. The constant force spring 2 winds around the upper body of the target person, which can bind the arms and torso of the target person, thus restricting the movement ability of the target person's arms. Since the steel fork body 1 and the constant force spring 2 can be separated, in some cases, even if one arm of the target person is wound, or even if the target person's arm is not wound, the target person can still be controlled by the steel fork body 1, so that the steel fork body 1 does not lose its original function.

[0042] Reference Figure 2 and Figure 4 For the two mounting points of the constant force spring 2, one mounting point is located in the middle of the constant force spring 2, and the other mounting point is located near the end of the constant force spring 2. Specifically in this embodiment, one mounting point is located at the midpoint of the length of the constant force spring 2, and the other mounting point is located at one-third of the length of the constant force spring 2. The length of the constant force spring 2 is 3 - 4 times the distance between the two mounting points, and the length of the constant force spring 2 is 1.6 - 1.8 m.

[0043] During use, the area between the two mounting points of the constant force spring 2 touches the upper body of the target person. The constant force spring 2 winds around with the area between the two mounting points as the dividing line. The area between the two mounting points divides the constant force spring 2 into a long side and a short side, so that the time required for the long side and the short side of the constant force spring 2 to complete winding is different, enabling the short side of the constant force spring 2 to wind around the upper body of the target person first, and then the long side of the constant force spring 2 winds around the outside of the short side of the constant force spring 2, making the constant force spring 2 wind in an orderly manner.

[0044] Reference Figure 3 A protective sleeve 3 is sleeved outside the constant force spring 2. The protective sleeve 3 can protect the constant force spring 2, reduce the damage to the constant force spring 2 from the outside world, and the protective sleeve 3 can also reduce the harm of the constant force spring 2 to the target person, enabling the target person to be legally bound. Avoidance holes 31 for avoiding the mounting points are opened on the protective sleeve 3, facilitating the connection between the constant force spring 2 and the steel fork body 1 at the mounting points.

[0045] Reference Figure 2 and Figure 5 Magic tapes 4 are fixedly connected to both sides of the protective sleeve 3. The magic tape 4 on the side close to the steel fork body 1 has a hook surface, and the magic tape 4 on the side far from the steel fork body 1 has a loop surface. When the constant force spring 2 winds, the hook surface and the loop surface of the magic tape 4 can be adhered to each other, thus temporarily fixing the constant force spring 2, making it difficult for the target person to break free. Due to the setting of the magic tape 4, it is also convenient for the security personnel to untie the wound constant force spring 2.

[0046] The implementation principle of a restraint device for restraining the upper body in an embodiment of the present application is as follows: When an emergency occurs, a security personnel holds the steel fork body 1 and makes the constant force spring 2 approach the upper body of the target person. The constant force spring 2 is impacted and wound around the upper body of the target person. The magic tapes 4 adhere to each other, which can reduce the situation of the target person breaking free, thereby legally restricting the movement of the target person.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
