Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, in an embodiment of the present invention, a multifunctional combination wrench special for electrical equipment maintenance is provided, which includes a main body 1, where the main body 1 includes a wrench operating head 11 and an operating handle 12; wherein,
the operating handle 12 is made of an insulating material, a plug 2 is arranged at one end of the operating handle, which is far away from the wrench operating head 11, and a matching part 21 matched with a special wrench for fastening the secondary wiring terminal is arranged on the plug 2.
It should be noted that the wrench operating head 11 is a wrench head commonly used in life, and includes a wrench adjusting wheel, a wrench engaging tooth, a movable head, a sliding rod for adjusting the movable head to advance and retreat, and so on, and is not described in detail herein.
It can be understood that the wrench operation head 11 can be used in a place with a large space, for example, the wrench head 11 can be directly operated by an inherent wrench to fasten or loosen a nut, while the matching part 21 of the plug 2 can be used in a place with a small space to be fixed with a wrench special for fastening a secondary binding post to form a new wrench, and then the new wrench is inserted into the box of the second junction box of the current and voltage transformer body to fasten or loosen the nut. The operating handle 12 made of insulating material can cause short circuit and earth fault when the current and voltage transformer body is touched by mistake.
In order to further reduce the electrostatic conductivity on the end of the plug 2, the multifunctional combined wrench further comprises an insulating sleeve 3, and the insulating sleeve 3 is detachably sleeved on the outer wall of the plug 2; the insulating sheath 3 can be removed when a new wrench is formed by fixing the fitting portion 21 of the header 2 to a wrench dedicated for secondary terminal tightening.
In one embodiment, the plug 2 has a hexagonal structure, and the fitting portion 21 provided at the middle position of the plug 2 is a spring circular chuck capable of realizing automatic expansion and contraction.
In order to save labor during the use of the multifunctional combination wrench, at least one handle torque rod 4 is arranged on one end of the operating handle 12 facing the wrench operating head 11. In one embodiment, there are two handle torque rods 4, the two handle torque rods 4 are symmetrically arranged with the central axis of the operating handle 12 as the axis, and the two handle torque rods 4 are movably connected with the operating handle 12 through corresponding latches 5. For example, when the nut is not required to be tightened or loosened with a large force or not used, the two handle torque rods 4 move to a position parallel to the central axis of the operation handle 12, so that the occupied space of the multifunctional combination wrench can be saved (as shown in fig. 2); when the nut needs to be fastened or loosened with a large force, the two handle torque rods 4 rotate around the central axis of the operating handle 12, move to the position perpendicular to the central axis of the operating handle 12, and are clamped with the operating handle 12 through the corresponding lock catches 5, so that the effect of saving labor in fastening or loosening the nut can be achieved (as shown in fig. 1).
Furthermore, two grooves 31 are arranged on the end surface of the insulating sleeve 3 facing to one end of the wrench operating head 11; when the two handle torque rods 4 move to the positions parallel to the central axis of the operating handle 12, the ends of the two handle torque rods 4 far away from the wrench operating head 11 can be respectively accommodated in the corresponding grooves 31, so that the two handle torque rods 4 are prevented from being damaged due to collision.
The embodiment of the invention has the following beneficial effects:
in the embodiment of the invention, because one end of the multifunctional combined wrench is an inherent wrench, and the other end of the multifunctional combined wrench can fix the secondary terminal post fastening special wrench through the matching part on the plug to form a new wrench (such as a spring round chuck fixing sleeve wrench head), the multifunctional combined wrench can be used in a place with a vacant space (such as the inherent wrench for fastening or loosening a nut), and can also be used in a place with a narrow space (such as the inherent wrench for fastening or loosening the nut by stretching into the two junction box boxes of the current and voltage transformer body), the multifunctional combined wrench has flexible use, improves the working efficiency, and simultaneously, the operating handle connected between the two ends is made of an insulating material, thereby avoiding the phenomena of short circuit, grounding fault and the like when the multifunctional combined wrench is mistakenly collided with the current.
