Abstract
The utility model relates to a single-hook double-tongue tensioning-type ground wire clamp which is provided with an n-shaped hook and an operating rod connector. The n-shaped hook is connected with the operating rod connector through a steering device. The interior of the n-shaped hook is provided with a double-tongue type spring clamping piece. The outer side of a side edge of the n-shaped hook is provided with a nut. The tail end of the operating rod connector is hemisphere-shaped. The operating rod connector is equipped with a spring pin. A part, which contacts with a wire, of the clamp provided by the utility model employs a single-hook double-tongue mode. A part, which contacts with an insulating operating rod, of the clamp employs a mode of changeable angle. The clamp provided by the utility model can carry out comprehensive operation, and is suitable for flexible application in equipment at various kinds of angles. The tail part of the operating rod connector is hemisphere-shaped, which is convenient for the fast connection with an operating rod. The utility model solves a problem of a single operation angle of a conventional ground wire clamp. The clamp provided by the utility model guarantees fast and firm installation of a ground wire on a working site, which is convenient for the fast connection with the operating rod. The clamp is easy to use, is safe and reliable, needs no other ground wire clamps with different types, and can be installed on a wire at any angle or on a busbar.
Description
Technical field
The utility model relates to when a kind of high-tension apparatus has a power failure the two tongue tension-type earthing clamps of single hook that use while arranging the site safety measure.
Background technology
At present, known earthing clamp be " n " type and " C " type.Be divided into and use on the wire of high-tension apparatus place and use two kinds on bus bar.In actual use, the on-the-spot needs prepared two kinds of earthing clamps, and while running into vertical lead wire or bus bar, these two kinds of earthing clamps are all not handy, cause the installing earth connection to waste time, and the dangerous and unstable potential safety hazard of installing.
The utility model content
In order to overcome the deficiency of existing earthing clamp, the utility model provides a kind of single hook two tongue tension-type earthing clamps, this earthing clamp can not only be attached on normal device, and can be installed to easily at any angle on wire or bus bar, simple to operate, the on-the-spot earthing clamp that does not need to prepare in addition other models.
The utility model solves the technical scheme that its technical problem adopts:
The two tongue tension-type earthing clamps of single hook, there is n shape hook and action bars joint, described n shape hook is connected by transfer with the action bars joint, be provided with the double tongue type spring clip in n shape hook, the arranged outside of a side of n shape hook has nut, the end of described action bars joint is hemispherical, on the action bars joint, spring catch is installed.
Described transfer is comprised of knuckle and dovetail screw, and the quantity of described knuckle is two, and a knuckle is connected with the end of n shape hook, and another knuckle is connected with the top of action bars joint, and two knuckles are connected by the dovetail screw.
Advantage and effect that the utility model has are:
The two tongue tension-type earthing clamps of the utility model list hook are owing to having n shape hook and action bars joint, n shape hook is connected by transfer with the action bars joint, adopt single two tongue tension-types that hook with the wire contact site, the position contacted with insulating bar adopts the changeable angle formula.Can comprehensively operate, be adapted on various angle equipment using flexibly, because the afterbody of action bars joint is hemispherical, be convenient to be connected with the quick of action bars.Solved the problem of earthing clamp single operation angle in the past.Guaranteed the firmly installing fast of operation field earth connection, be convenient to be connected with the quick of action bars, use is simple, safe and reliable, does not need to prepare in addition the earthing clamp of other models.Can guarantee to be installed at any angle on wire or bus bar, easy to operate, save time, can also guarantee the complete of operation field safety measure.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model while using on wire.
Fig. 2 is the structural representation of the utility model while using on bus bar.
1.n shape hook in figure, 2. double tongue type spring clip, 3. nut, 4. dovetail screw, 5. knuckle, 6. spring catch, 7. action bars joint, 8. wire, 9. bus bar.
Embodiment
As shown in Figure 1, the two tongue tension-type earthing clamps of the utility model list hook have n shape hook 1 and action bars joint 7, a side of described n shape hook 1 is connected by transfer with action bars joint 7, be provided with double tongue type spring clip 2 in n shape hook 1, the arranged outside of a side of n shape hook 1 has nut 3, the end of described action bars joint 7 is hemispherical, and spring catch 6 is installed on action bars joint 7.
Described transfer is comprised of knuckle and dovetail screw 4, the quantity of described knuckle is two, a knuckle 5 is connected with the end of n shape hook 1, and another knuckle 5 is connected with the top of action bars joint 7, and two knuckles are connected by dovetail screw 4.
Described n shape hook 1, double tongue type spring clip 2, nut 3 and a knuckle form head of the present utility model, spring catch 6, action bars joint 7 and another knuckle 5 form afterbody of the present utility model, with dovetail screw 4, head and afterbody are fixed together, point-blank the time, can meet the requirement of operation on general wire 8 when head of the present utility model and afterbody.
As shown in Figure 2, between head of the present utility model and afterbody, can change arbitrarily angle by knuckle, fixing with dovetail screw 4 after operation, can meet the requirement operated on bus bar at any angle.Solve the problem of known earthing clamp single operation direction, can guarantee the firmly installing fast of operation field earth connection.
