Description

Steel fork net

Technical Field

The invention relates to a steel fork net.

Background

At present, the situation of social security is severe and complex, and the danger and challenge moment faced by a guard in the process of safeguarding political safety, maintaining social stability and guaranteeing the safety of people exist.

Due to different security conditions in various places, the equipment is relatively uneven. Especially, in the place with good public security, the consciousness of equipment allocation is relatively lagged and the new and old equipment is not updated in time because the vicious case (thing) never happens all the year round. For places with higher case rate or seriously injured people in treatment, the awareness of equipment allocation and update is more advanced; in addition, the individual difference of the personnel has great difference of safety consciousness and actual combat consciousness, so that the gambling spirit exists mostly, the danger is not always considered to occur on the personnel, and the greatest danger is not known to be feared that the danger is not realized. Meanwhile, equipment manufacturers, suppliers and distributors hardly know the current situation of the basic level line, the theory is larger than the practice, and most of the equipment tends to research and produce high-end equipment with large profit space due to the consideration of benefits, but the equipment is difficult to be equipped at the basic level line. Thus, the best equipment is one that is visible and just as it is without spending too much time on practice.

First, the advantages and disadvantages of the existing steel fork

The existing steel fork is a novel non-lethal apparatus which has an effect on disturbing security when the joint is dangerous, and can effectively protect the safety of personnel on duty. The existing steel fork is originally developed and equipped mainly aiming at the campus safety hazards frequently occurring in recent years, has the characteristics of high strength, light weight, flexibility, portability, flexible application, reusability and the like, and is also listed as an internal safety protection device by communities, schools, industrial and mining enterprises and other units.

The material and application related information of the steel fork are introduced from the internet, but in actual practice, the functions of the existing steel fork are not as perfect as those described in the specification. In fact, the steel fork is very easy to be seized and utilized by the other side in the confrontation, so that the steel fork becomes a sharp tool in the hand of the other side and causes more damage to the operator.

Second, the conventional use method of the existing steel fork

Generally, the prior steel fork has the following three using methods:

1. cross forking method

The fork mouth is taken as a horizontal plane. Aims to achieve the purpose of limiting target action by forking the waist and abdomen of the user; by combining the characteristics and design ideas of the steel fork, after the fork strikes the waist and abdomen of the opposite side, the fork can be controlled in an effective space by timely using obstacles such as a wall body, a corner and the like as supports; secondly, the correct use of the steel fork can also ensure that the position control personnel and the other party keep a certain safe distance, so that the position control personnel can not attack the other party in the first time. Therefore, the cross-cut method always affects the vast base layer of people.

2. Method of oblique forking

The steel fork is held at an angle of 45 degrees, and the fork strikes the connecting line of the neck, the chest and the armpit of the target to destroy the gravity center of the other side, so that the target cannot exert force effectively. Compared with the transverse fork method, the oblique fork method has better fighting effect and stronger practicability and can destroy the gravity center of the other side.

3. Is used cooperatively

The steel fork can be matched with other equipment and the like for use; if the control personnel hold the steel fork to approach from the back of the opposite side, when the control personnel are not in readiness, the control personnel quickly attack the target popliteal fossa (the back side of the knee) by using a 'cross fork' method to force the control personnel to lower the gravity center, and the control personnel knock down the control personnel on the ground by means of the resultant force of an antiriot shield and the like, thereby effectively controlling the control personnel.

Analysis of actual combat effect of three-steel fork

If the vast staff at the basic level is trained by professional systems, can be skillfully master the using method and can be flexibly applied, the situation can be effectively treated. However, due to the contradictory influence of the training, the time for the basic level personnel to perform systematic training is limited, and the requirement on the user is high, so that the further constraint control on the target cannot be safely and effectively implemented by using the steel fork conventionally, and if the target cannot be effectively constrained within a short time, stronger resistance and even extreme measures are probably adopted due to stimulation, so that the risk is increased unnecessarily. If the waist of the cross fork method can limit the movement of the cross fork in theory, but on the premise that the forces of two parties are balanced or the force of one party is obviously superior to that of the other party, the stopping effect of the steel fork can be effectively exerted, moreover, the waist is the source of the force, and if no barrier or support exists in a treatment site, the other party can easily swing away; even if the target can be limited in the effective space and cannot move, the two hands of the target can still move, and if the danger source cannot be controlled at the first time, the target can still do dangerous actions such as grabbing, cutting, splitting, stabbing, throwing and the like. Therefore, on the basis of the transverse fork method, through long-term teaching practice and repeated tests, an oblique fork method is developed, namely, the opening direction of the steel fork is inclined by 45 degrees to be aligned with the connecting line position of the neck, the chest and the armpit of a target, and the purpose of stopping the target can be achieved by applying force slightly. When the method is used, even though the hands are not effectively restrained, some dangerous actions can be performed, the strength of the actions can be seriously influenced, and the danger coefficient can be greatly reduced, so that the threat of the target to the local is effectively reduced. When the steel fork is matched with instruments such as a shield and the like for use, the attacking and defending effect is better, but the difficulty is extremely high when the steel fork is further controlled, the number of sudden factors is large, the close control after falling to the ground is also important skills of operators (not discussed too much), and in conclusion, the steel fork has larger using defects at present.

Therefore, the steel fork is optimized and improved, a steel fork net is developed, the actual combat application effect of the steel fork is greatly improved, and the steel fork net is favored by basic personnel.

Detailed Description

In order to more clearly illustrate the present invention, embodiments of the present invention are further described below with reference to the accompanying drawings.

Example one

As shown in figure 1, a steel fork net, including handle, fork ring, the handle with the fork ring rigid coupling, the fork ring is hollow arc structure, this kind of steel fork net still includes the net ring, the net ring with the fork ring is connected, and with the fork ring forms the circular shape rack, be provided with the string bag on the rack. The net ring and the fork ring are connected in a mode that the net ring penetrates through the hollow part in the fork ring and then is fixed at the other end. The material of net ring adopts steel wire or billet, or adopts synthetic material to guarantee to have sufficient intensity and guarantee can not warp when not contacting the foreign object, can warp when contacting the foreign object, especially contact the people, in order to prevent to hurt the people.

One of the methods for making such a steel fork net is described below, but is not limited to such a method.

The first step, take off the black plastics protective sheath at steel fork jaw both ends to 8 iron wires that will prepare penetrate by jaw one end, wear out from the other end.

The second step, it is two with the elbow that the vice goes out about 2 centimeters with the iron wire both ends curved, utilize the elbow to hang iron wire both ends hook after, continue to tighten up the elbow with the vice to rotate the iron wire, hide into the nonrust steel pipe of steel fork jaw with elbow connection port, thereby avoid junction iron wire tip probably to cause the potential safety hazard of handling the in-process and the iron wire junction pine that probably causes when using for a long time to take off.

And thirdly, the two prepared sponge fishing rod plugs are respectively plugged into two ends of the fork head of the steel fork, so that the phenomenon that the connection between the iron bar and the pipe wall of the fork head is not tightly attached can be effectively relieved, and a certain buffering effect can be achieved. Because the stainless steel tangent plane at the two ends of the fork head of the steel fork is extremely sharp and is wound by the medical cloth adhesive tape, unnecessary injury to a treated object caused by rough front end in the using process can be avoided.

And fourthly, sleeving the fishing net opening with the iron wire for a circle, fixing the fishing net opening with black plastic bands, and cutting off the redundant parts of the bands by using scissors, wherein the distance between every two to three fingers is kept for each band, so that the compactness of the fishing net and the C-shaped bent pipe is improved, and a simple and complete steel fork net is manufactured.

The practical application of the steel fork net is described below.

The steel fork net has weak defense function in actual combat, so the steel fork net is matched with a shield or other instruments for use, and can better exert the restraint and control functions by means of the minimum combat unit group tactics, reasonable standing and cooperative coordination, thereby effectively preventing dangerous behaviors, controlling target objects and protecting the life safety of people and disposers. The steel fork net actual combat application process can be summarized as follows: standing, approaching and controlling.

One is the station.

The method comprises the following steps: taking two people as an example, the target proportion is 1 person.

By utilizing a minimum combat unit combined type combat method, the anti-riot shield is held in front for protection, the attention of the other party is attracted, and the steel fork net holding personnel monitor the weak hand side and the back side of the shield holding personnel for constraint control.

The second method comprises the following steps: taking three people as an example, the target proportion is 1 person.

The minimum operation unit separated type battle method is utilized, namely, a shield holding person and a steel fork holding person are combined, a third person holds the long stick to form a front-back clamping and striking station formation, namely, the anti-riot shield holding person protects the front, attracts the attention of the other person, the long stick holding person strikes, and the steel fork net holding person plays a role in restraint control.

The second is approach. When a specific dangerous behavior occurs, the tactical formation is hidden and close, language control is carried out according to law in the approaching process, and the solution is solved in a peaceful mode; the intention of not exposing action before implementing constraint control is determined to move and brake, meanwhile, the equipment attribute is combined to play the advantages of the equipment, the tactical formation is dynamically and timely adjusted according to the field environment and the treated object, and when the opportunity is mature, force is used according to law and success.

And thirdly, using. A user holds the handle at the rear end of the steel fork with one hand and the middle and rear ends of the steel fork with the other hand according to own habits, the net bag is arranged above, the net opening is downward, after the machine is mature, the upper half of the other side is rapidly covered from top to bottom, the opposite side is pulled for the first time, meanwhile, the shield or other instruments cooperatively exert force to force the opposite side to fall down, and then the other side is further restrained by means of the action of the C-shaped bent pipe at the front section of the steel fork and the fishing net. If the other side has violent resistance, the other side can further control the pressure by means of the shield.

Due to the elasticity of the net ring, if the net ring is not used for the first time, the net ring can be quickly recovered to finish the secondary use; and the net ring retainer is light in weight, so that even if the net ring retainer is carelessly hit the head of a target in use, the net ring retainer cannot worry about great damage.

And fourthly, controlling. After the steel fork net is used for effectively controlling the target, although the danger source is changed into a falling state from an upright state, the danger coefficient is reduced by half, the accident cannot be neglected at the moment, and certain difficulty and risk still exist when the danger source is further restrained. At this time, the legs of the user can be wound and restrained by the wide adhesive tape of the changing material, the reactive range of the user can be further reduced, the arms of the user can be controlled slowly by the pressure of the shield, and the effective restraint of the hands can be completed by the wide adhesive tape again. After the restraint is completed, the person must be inspected, and after the danger is completely eliminated, the person can be taken away for further treatment.

Because the extension part of the C-shaped bent pipe of the steel fork net is an 8-th iron bar and has certain extensibility, after the other side is sleeved by the net bag, the opposite resistance of over-excitation can not be implemented basically in a limited space, even if a target holds fiercers such as a dagger, a kitchen knife and an axe, the fiercers are difficult to cut (scratch) in a short time, and the best control time is gained for the subsequent treatment of personnel; meanwhile, the trunks of the other side can be quickly locked and controlled by using fork heads at two ends of the steel fork net and the ground as supports, so that the trunks are abandoned to resist, and the other side is further restrained and controlled by another side to two side control personnel according to control links, so that the side control risks are effectively avoided.

Example two

On the basis of the first embodiment, since the size of the net ring is fixed, the adaptability to people of different body sizes may be insufficient. In addition, since the net ring is required to be sleeved from top to bottom at the beginning, the size of the net ring is necessarily much larger than that of a person, and after the net ring is sleeved, the person has a large movement space in the net ring, which is not beneficial to further uniform. Therefore, as an improvement, the following is adopted.

The handle is hollow, and a net ring tensioning device is arranged on the handle.

The handle is connected with the fork ring, a net ring channel is arranged at the position where the handle is connected with the fork ring, the net ring channel is hollow, and two ends of the net ring channel are respectively communicated with the fork ring and the hollow part of the handle. The net ring is inserted from two ends of the fork ring, one end of the net ring penetrates through the net ring channel and then enters the handle to be fixedly connected with the net ring tensioning device, and the other end of the net ring is directly fixed on the fork ring or the handle; or both ends of the net ring can be fixedly connected with the net ring tension device.

The net ring tensioning device comprises a tensioning bolt, a tensioning rod and a tensioning slideway positioned on the handle. The tensioning bolt can slide in the handle, the tensioning rod is fixedly connected to the tensioning bolt, and the tensioning rod can move in the tensioning slide way. The tensioning bolt is hollow, the tensioning rod passes through the hollow part of the tensioning bolt, and the net ring is arranged in the hollow structure of the tensioning bolt and is fixed by the tensioning rod. The tensioning slide way comprises a straight slide way and a safety slide way, the safety slide way is a branch slide way arranged beside the straight slide way, and the tensioning rod can not move in the direction close to the steel fork any more after entering the safety slide way.

Under the structure, after the danger source is sleeved by the net ring, the tensioning rod is pulled, the tensioning bolt is driven to slide in the handle, and the net ring is contracted, so that the danger source can be better controlled.
