Abstract
The utility model discloses a self-buckling and self-unlocking high-voltage insulated operation rod joint. A connecting loop is arranged on the insulated operation rod joint and internally provided with a connecting shaft which can rotate around the inner cavity of the connecting loop. The connecting shaft is provided with two symmetrically arranged tongue pieces and two symmetrically arranged connecting posts. The tongue pieces are hinged to the two connecting posts in a manner of being able to swing up and down. The two tongue pieces are in a closed state normally and can be opened automatically when being squeezed upwards. After being opened, the two tongue pieces can reset and lock automatically. The self-buckling and self-unlocking high-voltage insulated operation rod joint of the utility model is high in usage reliability. A work head is of a mechanical type completely so that the work head can be changed so as to enable a single insulated rod or operation rod joint to have multiple functions. Simultaneously, the situations that operation personnel may need to try multiple times to hook a hook onto an operation position can be reduced, and the unsafe factors of long-time holding of the rod, incomplete switching, infirm connecting, and wrong touching of other phases can also be prevented.
Description
Technical field
The utility model relates to a kind of insulated operating rod, particularly a kind of self-clinching Self-unlocking High-Voltage Insulation hook stick connector.
Background technology
When practical operation high voltage isolator or falling type switch, because of insulating rod large than long elasticity, operating personnel may need repeatedly to attempt operation could hook operating position by hook, operating efficiency is low, also there is the not in place or not firm connection of switch in the long-time bar of lifting, other phases of false touch, working head and switch such as frequently clash at the unsafe factor.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of automatic locking of realizing is provided, and pulls up and down after snap close or promotes all can't deviate from; After rotating insulating rod, just can automatically terminate the self-clinching Self-unlocking High-Voltage Insulation hook stick connector of snap close.
A kind of self-clinching Self-unlocking High-Voltage Insulation hook stick connector, be provided with a clamping ring on the insulated operating rod connector, be provided with the connecting axle that can rotate around the clamping ring inner chamber in clamping ring, be provided with tongue piece and the joint pin of two symmetric arrays on connecting axle, what described tongue piece can swing up and down is hinged on two joint pins, two tongue pieces when normality in closure state, when being subject to upwards pushing, can automatically open, energy self-return and locking after opening, described tongue piece can make tongue piece automatically open after connecting axle rotates an angle.
The self-clinching Self-unlocking High-Voltage Insulation hook stick of this structure, in use, the insulated operating rod connector is connected with insulated operating rod, then with two tongue pieces, withstands the operation annulus and the insulated operating rod connector can be locked on the operation annulus, pull up and down after snap close or promote all can't deviate from; Rotate insulating rod the relative clamping ring of the connecting axle tongue piece after an angle that rotates is opened automatically, automatically terminate snap close.
Being embodied as of the motion mode of described tongue piece also is provided with for controlling the locating part of tongue piece motion on self-clinching Self-unlocking High-Voltage Insulation hook stick, be provided with cylindrical hole in clamping ring, described cylindrical hole is divided into two sections, two sections section tails in cylindrical hole are the arc-shaped transition that radius increases gradually, two joint pins are arranged on a symmetrical position of connecting axle, tongue piece is hinged on joint pin, described locating part is arranged on the outside of joint pin and extends to the part that connecting axle matches with clamping ring, the part of locating part in connecting axle and clamping ring is the outer ring that is embedded into the outer ring of connecting axle and is hinged on connecting axle, described locating part withstands on the outer end of tongue piece to control the motion of tongue piece.
The locating part of this structure is controlled the mode of tongue piece, when connecting axle and clamping ring during in mated condition, locating part withstands on tongue piece, realize one-way movement to control tongue piece, also when being squeezed, open tongue piece, pulling down or during reverse isolation hook stick connector, when rotating insulating rod, make connecting axle after clamping ring rotates an angle, while making connecting axle turn to the large part of two sections section tail radiuses, because clamping ring aperture herein is greater than remaining part, therefore locating part will eject, now tongue piece will be opened, thereby make the insulated operating rod connector throw off from the operation annulus.
Be provided with return spring between clamping ring and connecting axle with the connecting axle self-return after facilitating rotation.
In sum, the utility model following advantage compared to existing technology:
Self-clinching Self-unlocking High-Voltage Insulation hook stick connector of the present utility model possesses self-clinching and Self-unlocking function, can be accurately during use and falling type switch draw ring closure, aim at draw ring and buckle gently draw ring once pushing away, after falling type switch is left behind, as long as just easily release of half-twist, facilitate the Field Force to operate and use.Self-clinching Self-unlocking High-Voltage Insulation hook stick connector dependability of the present utility model is high, working head is mechanical type fully, and replaceable working head makes insulating rod, a hook stick possess several functions, simultaneously, the minimizing operating personnel may need repeatedly to attempt operation could hook hook the situation of operating position, prevent from lifting for a long time bar and also have the not in place or not firm connection of switch, other phases of false touch, working head and switch such as frequently clash at the unsafe factor.Simultaneously, adopt the mechanical type working head, its cost only slightly increases.Can be widely used in annular device or uncinus on drop-type circuit breaker or line switching frame, there is great practical value and dissemination.
