Description

Technical Field

[0001] The invention relates to the technical field of hydraulic crimping pliers for electrical construction, in particular to a hydraulic crimping pliers for electrical construction. Background Art

[0002] In the electric power industry, it is often necessary to crimp the wires, cables or terminals of equipment. Currently, most of the crimping pliers used are portable, which is not only unstable to place, labor-intensive, and inconvenient to use, but also not durable and easy to damage. One crimping plier can only crimp one specification of wire or cable, and has poor versatility, which results in high cost of use. Therefore, it is necessary to design a hydraulic crimping plier for electrical construction with good versatility and low cost. Summary of the invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a hydraulic wire crimping pliers for electrical construction, which has good versatility, low cost and ingenious structure.

[0004] In order to achieve the above-mentioned invention objectives, the present invention provides the following technical solutions: a hydraulic wire crimping pliers for electrical construction, comprising a support frame, a hydraulic cylinder is fixedly installed on the top of the support frame, a return oil nut is fixedly installed on the front end of the hydraulic cylinder, a steering bearing is provided on the front side of the oil return nut, a hydraulic jack is fixedly installed on the front side of the steering bearing, a lower pressure block is provided on the front side of the hydraulic jack, an upper pressure block is provided on the front side of the lower pressure block, a pressure block baffle is provided on the front side of the upper pressure block, an upper pressure groove is fixedly installed on the top of the hydraulic jack, a lower pressure groove is fixedly installed on the bottom of the hydraulic jack, an upper handle is fixedly installed on the top of the oil return nut, a connecting shaft is fixedly installed on the front end of the upper handle, a telescopic shaft is provided in the upper handle, a rubber sleeve is fixedly installed on the rear end of the upper handle, and a lower handle is fixedly installed on the side below the upper handle and close to the hydraulic cylinder.

[0005] Preferably, circular grooves are provided on the top of the hydraulic jack, and the number of the circular grooves is four groups, and the circular grooves are evenly distributed on the edge of the hydraulic jack.

[0006] Preferably, the circular groove is provided with four positioning holes, the number of the positioning holes is four groups, and the positioning holes are distributed on the same circumference of the circular groove.

[0007] Preferably, the main bodies of the upper pressing block and the lower pressing block are in the shape of a cuboid, semi-hexagonal grooves are provided on the opposite sides of the upper pressing block and the lower pressing block, and the upper pressing block and the lower pressing block are relative to each other to form a hexagonal hole configuration in the middle.

[0008] Preferably, an elastic spring is provided on the inner side of the upper handle close to the connecting shaft, and the elastic spring is sleeved on the outer side of the connecting shaft.

[0009] Preferably, the support frame is composed of three support rods distributed at equal angles.

[0010] Compared with the prior art, the present invention has the following advantages: the support frame below the hydraulic crimping pliers for electrical construction can be opened when in use, so that the hydraulic crimping pliers for electrical construction can be placed stably anywhere. When the diameter of the crimped cable is too large and the crimping is too difficult, the telescopic shafts on the upper handle and the lower handle can be opened and stretched, which is very labor-saving to use. When the crimped cable is too thick and not easy to twist, the steering bearing can be used to adjust the direction of the upper and lower crimping grooves, so that the hydraulic crimping pliers for electrical construction can be better used. When it is necessary to crimp cables of different specifications, the end of the pressure block baffle can be retracted, and the upper and lower pressure blocks can be taken out along the groove between the upper and lower pressure grooves, and the countersunk screws can be unscrewed. The hydraulic crimping pliers for electrical construction have the characteristics of simple structure, ingenious design, easy use, stable placement, etc. By changing the size of the upper and lower pressure blocks, the pressure installation requirements of cables of different diameters can be met. The operation is convenient, and the effect of use is better than that of the traditional method. BRIEF DESCRIPTION OF THE DRAWINGS
