Abstract
Disclosed is a closed security fork. The closed security fork is characterized in that a connector is arranged on the upper portion of a telescopic steel pipe, lower steel pipes, upper movable joints, lower movable joints, middle steel pipes, upper movable joints, lower movable joints, upper steel pipes and plugs are respectively sequentially mounted two sides of the connector, a shaft is arranged between the upper movable joint and the corresponding lower movable joint, straight springs are mounted on two sides of each shaft, linkage belts are arranged inside the steel pipes on two sides of each joint, an upper lock pin and a lower lock pin are arranged on each linkage belt and respectively obliquely inserted onto the corresponding upper movable joint and the lower movable joint, two connecting belts fixed onto each lower steel pipe are arranged at the lower edge of the corresponding linkage belt, a lock pin with one fixed end is arranged between each upper movable joint and the corresponding lower movable joint at the outer ends of the closed security fork. The closed security fork has the advantages of simple and reliable design, effective control of movement range of a perpetrator to prevent development of situation during emergency.
Description
Technical field
The utility model relates to a kind of security fork, especially closed type security fork.
Background technology
At present, now the security steel fork of using in the society is semi-circular, and it can only guarantee that self is not injured, and can not control the scope of activities of executing victimization, uses very inconvenient, and relatively heavier.
Summary of the invention
In order to overcome the in-problem deficiency of prior art, the utility model provides a kind of novel closed type security fork.This closed type security fork, simplicity of design, easy to use, telescoping handle, designs this product at occasion, characteristics, the character that takes place at case, can prevent the generation of malignant event and reduce the degree of pushing comes to shove.
The technical scheme that its technical problem that solves the utility model adopts is: closed type security fork, connector is arranged at the top of band handgrip and telescopic steel pipe, and the both sides of connector are equipped with bottom steel pipe, articulation up and down, middle part steel pipe, articulation up and down, top steel pipe, plug respectively successively.Axle is arranged between the articulation up and down, and straight spring is equipped with in the both sides of axle.There is linkage steel pipe inboard, connector both sides, two lock pins are up and down arranged on the linkage, respectively oblique cutting is in articulation up and down, and there are two connecting bands that are fixed on the steel pipe of bottom in linkage bottom, and the outer end of closed type security fork has the fixing lock pin of an end up and down respectively between the articulation.
Closed type security fork, prong opens wide when standby, divides civilian and alert with two kinds.When incident takes place, to insert to executing victimization with closed type security fork, linkage pulling lock pin is under the effect of spring, and closed type security fork rapid closing, formation close ring entangle and execute victimization.Effectively control execute victimization scope of activities, check the development of events.Result of use is then better simultaneously for two covers.
Closed type security fork is a kind of many occasions security product.Be applicable to the multiple occasion of various public order incidents such as public security, security personnel, municipal administration, market school, especially be applicable to the security personnel of middle and primary schools, kindergarten, to preventing act of violence, preventing that malignant event from guaranteeing teachers and students' personal safety, bringing into play key effect.
The beneficial effects of the utility model are, closed type security fork, and simplicity of design is reliable, and the telescoping handle light and beautiful is easy to use, when there is something special, closely executes victimization with closed type security fork is slotting to executing victimization, entangling.Effectively control execute victimization scope of activities, check the development of events.
