The utility model provides a technical scheme that its technical problem adopted is: a C-shaped wire clamp for live working comprises an insulating shell, a baffle, a movable pressing buckle, a screw, a guide plate and a C-shaped clamp seat; the screw rod penetrates through the C-shaped clamping seat and is connected with the movable pressing buckle, the upper part of the guide plate is fixed with the baffle plate screw, and the lower part of the guide plate is fixed with the side surface of the C-shaped clamping seat through the screw; the guide plate comprises a longitudinal guide groove and a transverse guide groove; the movable pressing buckle comprises a semicircular pressing buckle A, a semicircular pressing buckle B, a pressing buckle connecting column, a coil spring and an elastic retainer ring; the pressure is detained the spliced pole and is passed the vertical guide way of coil spring and deflector and penetrate the semicircle and press and detain A and connect, the semicircle press to detain B and the semicircle press and detain A joint, two semicircles press to detain and keep original V-arrangement through the coil spring, circlip joint between pressure knot spliced pole and coil spring.

Furthermore, the activity press buckle along the vertical guide way motion of deflector.

Further say, C type holder have both sides arc splint, both sides arc splint in when the wire line footpath is inconsistent, the semicircle is pressed and is detained the space that the arc splint of downstream and C type holder both sides formed and dwindle gradually and compress tightly the wire, the activity is pressed and is detained the spliced pole through pressing and detain the horizontal guide way side-to-side motion compensation of deflector, finally compresses tightly the wire in the different line footpaths of the left and right sides simultaneously.

Further say, lower insulating casing on be provided with the lock hole of being convenient for to be connected with manipulator fastener mounting tool.

Further, C type holder under be provided with the apron through the fix with screw.

The utility model has the advantages that:

1. compared with the existing C-shaped wire clamp, the utility model adds the transverse guide and the longitudinal guide, only needs an external force to fix the wire clamp on the wire, and has simple structure and convenient installation;

2. the installation of both can the manual work, but also the installation of accessible manipulator, the practicality is wider.

Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1-2, a C-shaped wire clamp for hot-line work comprises an upper insulating shell 1-1, a lower insulating shell 1-2, a movable press buckle 5, a screw 11, a guide plate 2, a baffle 15, a C-shaped clamp holder 3, a cover plate 12 and a buckling hole 4; the lower insulating shell 1-2 is provided with a buckling hole 4 which is convenient to be connected with a manipulator wire clamp installation tool.

The screw rod 11 is arranged in the C-shaped clamping seat 3 in a penetrating way and is connected with the movable pressing buckle 5.

The guide plate 2 comprises a longitudinal guide groove 6 and a transverse guide groove 7, the transverse guide groove 7 is arranged below the longitudinal guide groove 6, the upper portion of the guide plate 2 is fixed with the baffle 15 through screws, and the lower portion of the guide plate is fixed with the side face of the C-shaped clamping seat 3 through screws. The deflector is detachable connection, compares in other guide structure, for example the guide post structure, and more nimble assembly methods can be realized to the deflector, also is convenient for follow-up maintenance and the change of pressing the knot to the activity.

The movable pressing buckle 5 comprises a semicircular pressing buckle A9, a semicircular pressing buckle B10, a pressing buckle connecting column 8, a coil spring 13 and a circlip 14, the pressing buckle connecting column 8 penetrates through the longitudinal guide grooves 7 of the coil spring 13 and the guide plate and penetrates through the semicircular pressing buckle A9 to be connected, the semicircular pressing buckle B10 is clamped on the semicircular pressing buckle A9 to be connected, the two semicircular pressing buckles keep an initial V shape through the coil spring 13, and the circlip 14 is clamped between the pressing buckle connecting column 8 and the coil spring 13 to prevent the coil spring 13 from deforming.

When the screw rod 11 receives the exogenic action rotatory, 5 vertical guide way 6 downstream along the deflector is pressed in the activity, and when 2 line footpaths of wire in the arc splint of 3 both sides of C type holder were inconsistent, the space that two semicircles pressed the arc splint of detaining downstream and C type holder both sides formed dwindles gradually and compresses tightly the wire, and 5 are pressed in the activity and are detained 5 and detained 7 side-to-side motion compensation at the horizontal guide way of deflector through pressing the spliced pole 8, finally compress tightly the wire of the different line footpaths of the left and right sides simultaneously.

The cover plate 12 is fixed below the C-shaped clamping seat 3 through screws, so that the screw rod can only do circular motion, and the screw rod is prevented from moving up and down.

While the foregoing description describes only certain embodiments of the invention, it is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
