Abstract
The utility model relates to a terminal box door handle, concretely relates to locking ejector half terminal box door handle. Its fixed cassette on being fixed in the case lid and the rotation handle that lies in fixed cassette interstitial hole position, the front end that rotates the handle is the labour contractor, and the rear end is equipped with spring bolt, characterized in that: rotate the handle and can make axial displacement in the interstitial hole of fixed cassette, be equipped with spring I between labour contractor and the fixed cassette, be equipped with spring II between spring bolt and the fixed cassette. The utility model provides an easily not hard up problem of ordinary terminal box door handle, can ensure the terminal box in electrical components do not receive the external environment condition to influence and damage with higher speed, but its wide application is in the transformer substation on the equipment terminal boxs such as mutual -inductor, isolation switch, switch.
Description
Technical field
The utility model relates to terminal box door handle, is specifically related to a kind of locking ejector half terminal box door handle.
Background technology
At present, electricity substation Outdoor Terminal Case as the corollary equipment of power plant and electric substation's high pressure primary equipment, main switching and the equipment operating control unit being used as the equipment secondary circuits such as transformer, primary cut-out, current transformer in transformer station.
Because terminal box is placed on open air, this just requires that the case lid of terminal box and casing must be fixed reliably, to prevent terminal box internal electronic element by external environment influence.
The case lid of existing terminal box and casing are fixed by ordinary handle.And ordinary handle exists fixing insecure defect, easily produce between case lid and casing and loosen, namely this can damage component, again can because of poorly sealed close and make electric elements moisture damage in terminal box.
Summary of the invention
The utility model is solve common terminal chamber door handle easily to produce loosening problem, have developed a kind of locking ejector half terminal box door handle.
The utility model is achieved by the following technical solution:
A kind of locking ejector half terminal box door handle, it includes the Fixing clamp-seat be fixed on case lid and the swing handle being positioned at Fixing clamp-seat interstitial hole position, the front end of described swing handle is labour contractor, rear end is provided with dead bolt, be characterised in that: described swing handle can move axially in the interstitial hole of Fixing clamp-seat, be provided with spring I between described labour contractor and Fixing clamp-seat, between described dead bolt and Fixing clamp-seat, be provided with spring II.
The elastic force of described spring I is greater than spring II.Under normality (case lid closed condition), spring II is in compressive state by the effect of spring I, and now, dead bolt can compress terminal tank wall and not loosen; When opening case lid, only need press swing handle, now spring I compresses by External Force Acting, and spring II recovers its length, and dead bolt is away from terminal tank wall, and then rotary motion handle just can open terminal case lid.
The front end of described Fixing clamp-seat is fixed with handle guide pin bushing, the labour contractor of described handle guide pin bushing and swing handle is slidably connected, described swing handle can move forward and backward along handle guide pin bushing, and the interstitial hole diameter of described Fixing clamp-seat is greater than the diameter of swing handle, and namely swing handle and Fixing clamp-seat do not come in contact.
Described dead bolt realizes fixing by former and later two nuts.During installation, first by the elasticity of front end nut regulating spring II, then by rear end nut, dead bolt is fixed.
The utility model solves the problem that common terminal chamber door handle easily loosens, and can guarantee that in terminal box, electric elements do not accelerate by external environment influence to damage, it can be widely used on the arrangement terminal casees such as mutual inductor in transformer station, isolation switch, switch.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is installation site figure of the present utility model.
Fig. 2 is concrete structure figure of the present utility model.
In figure, 1 swing handle, 2 case lids, 3 Fixing clamp-seats, 4 handle guide pin bushings, 5 labour contractors, 6 spring I, 7 dead bolts, 8 spring II, 9 nuts.
Detailed description of the invention
Accompanying drawing 1,2 is a kind of specific embodiment of the present utility model.It includes the Fixing clamp-seat 3 be fixed on case lid 2 and the swing handle 1 being positioned at Fixing clamp-seat interstitial hole position, the front end of described swing handle is labour contractor 5, rear end is provided with dead bolt 7, be characterised in that: described swing handle can move axially in the interstitial hole of Fixing clamp-seat, be provided with spring I 6 between described labour contractor and Fixing clamp-seat, between described dead bolt and Fixing clamp-seat, be provided with spring II 8.
Further, the elastic force of described spring I is greater than spring II.
Further, the front end of described Fixing clamp-seat is fixed with handle guide pin bushing 4, and the labour contractor of described handle guide pin bushing and swing handle is slidably connected, and the interstitial hole diameter of described Fixing clamp-seat is greater than the diameter of swing handle.
Further, described dead bolt realizes fixing by former and later two nuts 9.First by the elasticity of front end nut regulating spring II, then by rear end nut, dead bolt is fixed.
