When the clamping sleeve is used, the outer hexagon nut of the hydraulic pipe joint is firstly pre-tightened to a proper position, and mechanical limiting is carried out on the outer hexagon nut of the hydraulic pipe joint through the first step hole of the clamping sleeve body; and then, the anti-loosening screw is tightened to enable the clamping sleeve body to generate elastic deformation along the radial direction at the clamping groove and clamp the hydraulic pipe, so that the looseness prevention of the hydraulic pipe joint is realized. The utility model discloses a general type hydraulic pressure coupling locking cutting ferrule, simple structure, it is convenient to maintain, and the reliability is high, and locking effectual, the adaptation wide range, application prospect is extensive.

Description

Universal type hydraulic pipe joint anti-loosening clamping sleeve
Technical Field
The utility model belongs to the technical field of the hydraulic pressure pipe, concretely relates to locking cutting ferrule of general type hydraulic pressure coupling.
Background
The hydraulic pipe joint is a part for connecting two high-pressure oil pipes in a hydraulic system. The existing universal hydraulic pipe joint is directly pre-tightened through a joint nut when in use, and does not have the functions of looseness prevention and shock resistance. In special fields such as military industry and automobiles, a hydraulic pipeline is easy to have a high-frequency vibration phenomenon, so that a joint nut is loosened, and a hydraulic oil leakage fault and even a safety accident are caused. In order to solve the problems, the common solution is to increase the pre-tightening torque of the joint nut during assembly, but because the joint threaded pipe of the hydraulic pipe joint is made of the same or similar material as the joint nut in most cases, when the pre-tightening torque is large, the phenomenon of thread seizure is easily generated, so that the hydraulic pipe joint is damaged and is difficult to disassemble.
Disclosure of Invention
The utility model aims at providing a locking cutting ferrule of general type hydraulic pressure coupling to solve the problem that above-mentioned prior art exists.
In order to achieve the above object, the present invention provides the following solutions:
the utility model provides a general type hydraulic pressure coupling locking cutting ferrule, including cutting ferrule body and locking screw. The clamping sleeve body is used for clamping a hydraulic pipeline and limiting an outer hexagon nut of a hydraulic pipe joint to rotate, and the anti-loosening screw is used for being matched with the clamping sleeve body to apply clamping force to the hydraulic pipe.
The first step hole of the cutting sleeve body is of an inner hexagon and is used for being matched with an outer hexagon nut of a hydraulic pipe joint to prevent relative rotation between the first step hole and the outer hexagon nut; the second step hole of the cutting sleeve body is a circular through hole and is used for penetrating through a hydraulic pipe.
The clamping sleeve body is provided with a clamping groove along the axial direction from the end face, and the clamping force on the hydraulic pipe can be adjusted according to different widths of the clamping groove.
The clamping sleeve body is provided with symmetrical anti-loosening threaded holes at two sides for screwing in anti-loosening screws.
The beneficial effects of the utility model reside in that: the utility model provides a pair of general type hydraulic pressure coupling locking cutting ferrule can effectively avoid appearing because of the too big screw thread that leads to of joint nut pretension moment is stung die to can adjust joint nut's locking position according to operating condition needs. The hydraulic pipeline is clamped in an elastic deformation mode of the clamping sleeve body, the locking and shock-proof effects are good, and the clamping sleeve can be repeatedly used. The utility model provides a pair of general type hydraulic pressure coupling locking cutting ferrule, simple structure, processing convenience, easily assembly and maintenance, application prospect is extensive.

fig. 5 is a cross-sectional view of fig. 2.
In the figure: 1. the locking clamp comprises a clamp sleeve body, 2 locking screws, 3 first step holes, 4 second step holes, 5 locking threaded holes, 6 clamping grooves, 7 hydraulic pipes, 8 joint threaded pipes, 9O-shaped sealing rings and 10 sealing gaskets.
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 efforts belong to the protection scope of the present invention.
The utility model aims at providing a locking cutting ferrule of general type hydraulic pressure coupling to solve the problem that prior art exists.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
This example provides a general type hydraulic pressure coupling locking cutting ferrule, as shown in fig. 1, does the utility model discloses hydraulic pressure coupling locking cutting ferrule schematic diagram, including cutting ferrule body 1 and stop screw 2.
As shown in fig. 2 and 3, the first stepped hole 3 of the cutting ferrule body 1 is an internal hexagon and is used for matching with an external hexagon nut 11 of the existing hydraulic pipe joint to prevent relative rotation between the two; the second step hole 4 of the cutting sleeve body 1 is a circular through hole and is used for penetrating through the hydraulic pipe 7.
As shown in fig. 2 and 3, a clamping groove 6 is formed in the middle of the ferrule body by axially cutting the end face of the ferrule body in a linear cutting manner. The width of the clamping groove 6 can be determined according to the clamping force required by actual working conditions. The clamping sleeve body is provided with symmetrical anti-loosening threaded holes 5 on two sides.
As shown in fig. 4 and 5, when in use, the outer hexagonal nut 11 is firstly pre-tightened to a proper position and mechanically limited through the first stepped hole 3 of the ferrule body 1; and then the anti-loose screw 2 is tightened to enable the cutting sleeve body 1 to generate elastic deformation along the radial direction at the clamping groove 6 and clamp the hydraulic pipe 7, so that anti-loose is realized.
