Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of police equipment, and in particular relates to a police arresting fork. Background Art
[0002] There are many kinds of existing arresting forks, some of which only have the control function, and some of which not only have the control function, but also have harmful functions such as electric shock, smoke and spikes. However, in actual police activities, some people who need to be controlled are not capable of harming others, such as some mentally ill patients. For such people, arresting forks with harmful functions seem to be too harmful and are easy to cause accidental injuries. Therefore, non-harmful arresting forks are generally used, but non-harmful arresting forks generally come in two forms, one is an open semicircular arc, and the other is an openable and closable circular ring. Both have poor control capabilities, and the arrested person is easy to break free. However, the reasons for the poor control capabilities of the two are different. The semicircular arresting fork requires environmental cooperation, and the arrested person needs to be pressed on the ground or against the wall or other people to cooperate with the shield. The open and closed circular ring, because it needs to cover the limbs of the arrested person when it is opened, will inevitably cause its diameter after closing to be thicker than the limbs of the arrested person, and the limbs of the arrested person are also easy to fall out. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a police arrest fork, which is used to solve the technical problem that the arrest fork in the prior art has poor control ability and is easy for the arrested person to break free.
[0004] The utility model solves the above technical problems with the following technical solutions: a police arrest fork, comprising:
[0005] outer coat rod;
[0006] A movable rod body, the movable rod body is inserted from one end of the outer rod;
[0007] A limiting arc, the limiting arc being arranged at the end of the movable rod;
[0008] An articulated block, the articulated block being arranged at the middle portion of the movable rod body;
[0009] Two restraining rings, one end of each of the two restraining rings being hinged to two ends of the hinge block respectively;
[0010] Two connecting rods, one end of the connecting rod head is hinged to the constraint ring, and the other end is hinged to the outer sleeve rod;
[0011] A positioning structure is provided between the movable rod body and the outer sleeve rod.
[0012] The movable rod body in the utility model can be extended and retracted in the outer rod. When the movable rod body is extended, it drives the restraint ring to open, and when it is retracted, it drives the restraint ring to close. When the limiting arc at the front end of the movable rod body abuts against the limbs of the controlled person, the movable rod body retracts, the restraint ring closes, and the movable rod body will be fixed in the outer rod under the action of the positioning structure, so that the limbs of the controlled person will be restrained between the restraint ring and the limiting arc. Since the limiting arc reduces the space, it is difficult for the limbs of the controlled person to break free, thereby achieving a good arresting effect.
[0013] Further: the positioning structure includes a first positioning hole and a positioning pin;
[0014] The positioning hole is provided on the outer sleeve;
[0015] The positioning pin is arranged on the movable rod body, and the positioning pin comprises a mounting seat, a limiting column, a pin and a spring. The limiting column is arranged on the mounting seat, the pin is arranged in the limiting column, and the spring is arranged between the pin and the limiting column.
[0016] The beneficial effect of adopting this step is that the positioning pin can be pressed, and when not in use, the pin will shrink in the limiting column under the action of the outer rod until the pin moves to the position of the first positioning hole. The pin extends out under the action of the spring and clamps the first positioning hole to achieve the fixation of the movable rod body and the outer rod.
[0017] Furthermore: the outer casing rod is also provided with an extension rod, and the extension rod is sleeved outside the outer casing rod;
[0018] The outer sleeve rod is provided with the positioning pin, and the extension rod is provided with two second positioning holes.
[0019] Beneficial effects of adopting this step: In some special scenarios, the distance between the police officer and the accused person is too far and they cannot approach each other, so it is necessary to extend the operating range of the capture fork by lengthening the rod.
[0020] Furthermore: a handle is provided at the tail end of the outer rod or the extension rod.
[0021] The beneficial effect of adopting this step is that the grip can be held by the police officer to improve the control of the capture fork.
[0022] Furthermore: the outer ends of the limiting arc and the restraining ring are provided with protective sleeves.
[0023] The beneficial effect of adopting this step: the limit arc and the restraint ring are made of metal, and there may be sharp chamfers or burrs at the ends. There is a risk of scratching when controlling important parts such as the neck of the controlled person. The protective cover can protect the controlled person.
[0024] Furthermore, the outer sleeve rod, the movable rod body and the extension rod are made of stainless steel thin tubes.
[0025] The beneficial effect of adopting this step is that the stainless steel thin tube has high overall strength and light weight, and can reduce the police officer's control strength without affecting the quality of the capture fork.
[0026] The beneficial effects of the utility model are:
[0027] 1. The restraint ring of the capture fork in the present application is an openable and closable structure. The restraint ring after closing can trap the controlled person, and combined with the limit arc, the activity space in the restraint ring can be further reduced to prevent the controlled person from escaping;
[0028] 2. An extension rod can be added outside the outer rod to increase the operating range of the capture fork. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Example
[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a police arrest fork, comprising:
[0046] Outer rod 1;
[0047] A movable rod body 3, wherein the movable rod body 3 is inserted from one end of the outer rod 1;
[0048] A limiting arc 31, wherein the limiting arc 31 is arranged at the end of the movable rod 3;
[0049] An articulated block 4, the articulated block 4 being arranged at the middle part of the movable shaft 3;
[0050] Two restraining rings 2, one end of each of the restraining rings 2 being hinged to two ends of the hinge block 4 respectively;
[0051] Two connecting rods 5, one end of the rod head of the connecting rod 5 is hinged to the constraint ring 2, and the other end is hinged to the outer sleeve rod 1;
[0052] A positioning structure is provided between the movable rod body 3 and the outer rod 1 .
[0053] In the utility model, the movable rod body 3 can be extended and retracted in the outer rod 1. When the movable rod body 3 is extended, it drives the constraint ring 2 to open, and when it is retracted, it drives the constraint ring 2 to close. When the limiting arc 31 at the front end of the movable rod body 3 abuts against the limbs of the controlled person, the movable rod body 3 retracts, the constraint ring 2 closes, and the movable rod body 3 will be fixed in the outer rod 1 under the action of the positioning structure, so that the limbs of the controlled person will be constrained between the constraint ring 2 and the limiting arc 31. Since the limiting arc 31 reduces the space, it is difficult for the limbs of the controlled person to break free, thereby achieving a good arresting effect.
[0054] On the basis of the above technical solution, the positioning structure includes a first positioning hole 6 and a positioning pin 9;
[0055] The positioning hole 6 is provided on the outer sleeve rod 1;
[0056] The positioning pin 9 is arranged on the movable rod body 3, and the positioning pin 9 includes a mounting seat 91, a limiting column 92, a pin 94 and a spring 93. The limiting column 92 is arranged on the mounting seat 91, the pin 94 is arranged in the limiting column 92, and the spring 93 is arranged between the pin 94 and the limiting column 92; wherein the mounting seat 91 can be welded or riveted to the movable rod body 3, and the space occupied by the positioning pin 9 can be compensated by removing or compressing the material at the corresponding position on the movable rod body 3; the limiting column 92 is a hollow column, and a limiting ring is also provided at the bottom of the pin 94.
[0057] The positioning pin 9 can be pressed. When not in use, the pin 94 will shrink in the limiting column 92 under the action of the outer rod 1 until the pin 94 moves to the position of the first positioning hole 6. The pin 94 extends out under the action of the spring 93 and clamps the first positioning hole 6 to fix the movable rod body 3 and the outer rod 1. In addition, by adjusting the position of the first positioning hole 6, the movable rod body 3 and the outer rod 1 are fixed while the two constraint rings 2 are just closed.
[0058] On the basis of the above technical solution, the outer sleeve rod 1 is further provided with an extension rod 8, and the extension rod 8 is sleeved outside the outer sleeve rod 1;
[0059] The outer rod 1 is provided with the positioning pin 9 (the connection method of the positioning pin 9 and the outer rod 1 here is the same as the connection method of the positioning pin 9 and the movable rod body 3 mentioned above), and the extension rod 8 is provided with two second positioning holes 81, and the two second positioning holes 81 are located at both ends of the extension rod 8, respectively, to achieve the positioning effect when the outer rod 1 is retracted in the extension rod 8 and the outer rod 1 is extended out of the extension rod 8.
[0060] In some special scenarios, the distance between the police officer and the accused person is too far and they cannot approach each other, so the extension rod 8 is needed to extend the operating range of the capture fork.
[0061] On the basis of the above technical solution, a handle 7 is provided at the tail end of the outer sleeve rod 1 or the extension rod 8 .
[0062] The grip 7 can be held by the police officer to improve the control of the arresting fork.
[0063] On the basis of the above technical solution, the outer ends of the limiting arc 31 and the restraining ring 2 are provided with protective sleeves.
[0064] The limiting arc 31 and the restraining ring 2 are made of metal, and their ends may have sharp chamfers or burrs, etc., which may cause the risk of scratches when controlling important parts such as the neck of the controlled person. The protective cover can protect the controlled person.
[0065] On the basis of the above technical solution, the outer sleeve rod 1, the movable rod body 3 and the extension rod 8 are made of stainless steel thin tubes.
[0066] The stainless steel thin tube has high overall strength and light weight, which can reduce the police officer's control strength without affecting the quality of the arrest fork.
[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
