Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present embodiment provides a ground-operable lifting loop resistance testing clamp device, which includes a base 1, a lifting rod is installed above the base 1, the lifting rod includes a screw rod 9 and a sleeve 3 sleeved outside the screw rod 9, an inner cavity of the sleeve 3 is provided with an internal thread matched with the screw rod 9, a motor 10 is fixedly installed at the bottom of the screw rod 9, and an output shaft of the motor 10 penetrates through the base 1 and is fixedly connected with the bottom of the screw rod 9 to provide power for the screw rod 9. The screw rod 9 can drive the sleeve 3 to move up and down under the action of the threads in the rotating process, so that the lifting is completed.

As shown in fig. 2, the outside of sleeve 3 still is provided with spacing section of thick bamboo 2, spacing section of thick bamboo 2 is located the outside of sleeve 3, and sleeve 3 can slide from top to bottom in spacing section of thick bamboo 2, spacing section of thick bamboo 2 fixed mounting is on base 1, the outside fixed mounting of sleeve 3 has vertical retort 11, the vertical retort that matches with vertical retort 11 is seted up to the lateral wall of spacing section of thick bamboo 2, vertical retort 11 and vertical retort play spacing effect to sleeve 3, avoid sleeve 3 to follow the rotation of lead screw 9, thereby make lead screw 9 accomplish sleeve 3's lift at the pivoted in-process.

As shown in fig. 3, sleeve 3's top fixed mounting has installation piece 6, installation piece 6 is as the installation department of fastener 5, fastener 5 is installed in the side of installation piece 6, the handle that fastener 5 is located the bottom is connected through the pivot with installation piece 6, fastener 5 can rotate round the pivot, thereby accomplish the angle modulation of fastener 5, and go back fixed mounting on the handle of fastener 5 bottom has spacing ring 7, a plurality of spacing holes have been seted up on spacing ring 7, and spacing hole uses fastener 5 and installation piece 6's rotation center to be annular array distribution as the center, and a spacing hole has also been seted up on installation piece 6, through the round pin hub connection between spacing hole of spacing ring 7 and the spacing hole of installation piece 6. The wire clamp 5 is provided with wires on two handles.

When the angle of the wire clamp 5 needs to be adjusted, the pin shaft is only required to be taken out of the limiting hole, then the wire clamp 5 is rotated upwards or downwards, and after the wire clamp is rotated to a proper angle, the pin shaft is inserted into the limiting hole, and then the fixation of the wire clamp 5 can be completed.

The fastener 5 is located fixed mounting on the handle on upper portion and acts as go-between 4, and act as go-between 4 extends to the bottom of spacing section of thick bamboo 2, when needing to measure the electric current or the voltage of circuit breaker, only need act as go-between with the hand pulling downwards, make two handles between the fastener 5 be close to each other, the chuck of fastener 5 alright with opening, thereby can place the chuck on the circuit breaker that needs the detection, loosen at last and act as go-between 4, make the chuck of fastener 5 press from both sides tight circuit breaker and can detect the circuit breaker.

In a further embodiment, since the handle angle of the wire clamp 5 is adjusted when the wire clamp 5 is adjusted in angle, the pull wire 4 is in a vertical state in this state. For example, when the clip 5 is biased to the upright position, the angle between the handle and the pull cord 4 is greater than 90 degrees, and when the pull cord is pulled, there is an insensitivity, and if it is desired to open the clip 5 to the same opening as when it is placed horizontally, a large force is required. Therefore, in the present embodiment, in order to facilitate the use of the pulling wire, the pulling wire 4 penetrates the handle at the bottom of the wire clamp 5, and the edge of the penetrating part is provided with a plurality of rotating shafts 8 capable of rotating, and the pulling wire 4 is positioned between the adjacent rotating shafts. No matter how the wire clamp 5 rotates, the stay wire 4 can turn at the rotating shaft 8, so that the handles of the stay wire 4 and the wire clamp 5 are always kept in a vertical rotating state, and when the stay wire is pulled, all the pulling force generated by the stay wire 4 is taken as the pulling force between the handles, so that the handles of the wire clamp 5 are close to each other and more labor is saved.

In this embodiment, in order to carry out better protection to acting as go-between and wire, the through hole has been seted up on the vertical retort 11, and act as go-between 4 is installed in the through hole, and the bottom of acting as go-between 4 is installed in erecting the groove moreover, and the wire also is placed in through hole and erecting the groove in addition, and the wire outside is provided with insulating rubber skin, and the outside of acting as go-between 4 also is provided with insulating rubber, uses safelyr.

In a further embodiment, as shown in fig. 4-5, in order to facilitate the use of the pulling wire 4, the supporting handle 12 is rotatably mounted on the edge of the vertical groove at the bottom, the bottom of the pulling wire 4 is fixedly connected with the supporting handle 12, and when the pulling wire 4 is pulled, the supporting handle 12 is only rotated outwards to move the bottom of the pulling wire 4 downwards, so that the pulling wire 4 can bring the handles of the wire clamps 5 close to each other, thereby replacing the clamping heads of the wire clamps 5.

In a further embodiment, as shown in fig. 4-5, a supporting plate 13 capable of rotating downwards is rotatably mounted at the bottom edge of one side of the supporting handle 12 close to the vertical groove, a groove for mounting the supporting plate 13 is formed in the supporting handle 12, the supporting handle 12 can be opened after rotating downwards to a proper angle, the edge of the supporting plate 13 is just opened in the vertical groove, and forms a triangular structure together with the supporting handle 12 and the vertical groove, so that the supporting handle 12 always provides a pulling force for the pull wire 4, the chuck of the wire clamp 5 is always in an opened rotating state, positioning between the chuck and the circuit breaker is facilitated, when the chuck is placed at a position where the circuit breaker needs to be measured, the supporting plate 13 can be retracted into the groove, the pulling force of the pull wire 4 is removed, and the chuck is clamped, so that the wire clamp 5 and the circuit breaker are clamped together. Whole operation process will open the location between fastener 5, fastener 5 and the circuit breaker and fastener 5 divide into a plurality of operating procedure to the centre gripping between the circuit breaker, when using, has avoided the degree of difficulty that a plurality of step coincidence caused, and it is easier to use.

The bottom fixed mounting of base 1 has the supporting leg, and the universal wheel is installed to the bottom of supporting leg, and the universal wheel makes base 1's removal more convenient.

In a further embodiment, in order to adapt the pulling wire 4 to different heights, the bottom of the pulling wire 4 is connected with the supporting handle 12 through a bolt, and when the pulling wire 4 is too long in use, the bolt can be loosened, the pulling wire 4 is tightened, and then the bolt is tightened to fix the pulling wire with the supporting handle 12 again.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
