Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and should not be considered as limiting the invention.

The utility model discloses a novel insulator overhead instrument. Wherein, fig. 1 shows a schematic structural diagram of an insulator overhead tool according to an embodiment of the present invention; fig. 4 shows the locking pin 401 mounted at the insulator steel cap 400.

As shown in fig. 1, the insulator pin tool 100 is a single piece, and may be made of cast iron or other hard material, including a head portion 101, a handle portion 102, and a tail portion 103. The head 101 is hook-shaped. The middle part is a long straight hand-held part 102, one end of which is connected with the head part 101, and the other end is connected with the tail part 103. Of course, the handle 102 may have other shapes or configurations as long as it is easy to grasp. The tail 103 is at an angle, preferably a right angle, to the hand-held portion 102. The design facilitates the hand to abut against the tail part 103 when gripping the hand-held part 102, thereby being assisted, facilitating the opening of the locking pin 401 and preventing the hand from falling off from the hand-held part 102 when gripping the hand-held part 102.

The tail part 103 is provided with a hole 104 near the end part, and can be threaded for carrying.

Turning now to fig. 2-3, a head 101 in the shape of a hook is shown. As shown, head 101 includes hook 201, the outer surface of which is curved in an inwardly concave arc to match the outwardly convex arc of the outer surface of steel cap 400. Also, the hook 201 has a protrusion 301 at its tip end, which is sized to match the size of the hole exposed when the locking pin 401 is in the locked state. As shown in fig. 3, the bottom of the protrusion 301 has a flange, and the width gradually increases from the flange to the bottom, and then the width is maintained until the bottom. Due to the design, if the locking pin of the insulator with larger size needs to be opened on site, the head part 101 can gradually extend into the locking pin hole from the convex part 301 because the locking pin hole is correspondingly larger until the outer surface of the trapezoidal part is clamped with the locking pin hole, and the locking pin is opened by utilizing the lever principle.

Generally, the insulator overhead tool 100 of the present invention is designed to be substantially Z-shaped.

When the insulator overhead tool 100 is used for opening the locking pin 401, an operator can grasp the handheld portion 102, attach the arc surface of the hook 201 to the outer surface of the steel cap 400, extend the protruding portion 301 at the top end of the hook 201 into the hole of the locking pin 401, clamp the flange just outside the locking pin hole (please refer to fig. 4 for the steel cap 400 and the locking pin 401 thereof), and force upwards to open the locking pin 401.

The present invention is not limited to the above-described embodiments, and various modifications and variations can be made by those skilled in the art in light of the teachings of the present invention. All such modifications and variations are intended to be included herein within the scope of this disclosure. While the preferred embodiments of the present invention have been illustrated in the accompanying drawings, in actual practice, the present invention does not necessarily include all of the illustrated features in order to obtain all or some of the advantages of the invention. Therefore, the scope of the present invention should be determined not by the preferred embodiments disclosed in the present application, but by the contents of the appended claims.
