Abstract
The utility model relates to an adjustable device of cutting ferrule formula coupling steel pipe length, include the joint body and be located the cutting ferrule of joint body opening part, the cutting ferrule passes through the nut and is fixed in the opening outside of the joint body, through the inside dog that adds adjustable position at the coupling, can the front and back adjustment step degree of depth, the long dog of steel pipe is adjusted backward, and the dog that the steel pipe is short is adjusted forward, finally finds the position that is fit for steel pipe length, can be so that when installing the steel pipe through the device, through mounted position's adjustment, will connect to install on the most suitable position, need not carry out cutting process again to the steel pipe, and do not influence the reliability of connecting.
Description
Technical Field
The utility model relates to a connection structure device field specifically is the adjustable device of cutting ferrule formula coupling steel pipe length.
Background
Due to the limitation of the product processing technology and the equipment installation precision, when a hydraulic pipeline is installed on machine equipment, the actual distances of the connecting interfaces at the two ends of the pipeline cannot be completely consistent, so that the uniformly cut steel pipes cannot be installed, and the steel pipes need to be cut or reworked again on site according to the actual installation distance. Due to installation site conditions, the cut length of the on-site steel pipe is difficult to control accurately, resulting in the pipe still being too long or short when installed. Too long results in failure to install and rework to do again, while too short results in the tubes not being installed in place and having to be discarded. Various problems make field installation very inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an adjustable device of cutting ferrule formula coupling steel pipe length is provided to solve the defect that exists among the prior art.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
the device for adjusting the length of the steel pipe of the cutting sleeve type pipe joint comprises a joint body and a cutting sleeve positioned at the opening of the joint body, wherein the cutting sleeve is fixed on the outer side of the opening of the joint body through a nut; a stop block is arranged in the joint body, a thread structure matched with an inner hole of the joint body is arranged on the excircle of the stop block, and the position of the stop block can be adjusted forwards and backwards in the joint body through threads;
furthermore, the inner hole of the joint body is designed with threads, and the length of the threads is greater than the thickness of the stop block and is used for adjusting the position of the stop block;
the utility model has the advantages that: through adding the dog in the coupling inside, the position of regulation dog around can, the dog of steel pipe length is backward adjusted, and the dog of steel pipe short is forward adjusted, finally finds the position that is fit for steel pipe length after, installs.

Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, the device for adjusting the length of the steel pipe of the ferrule type pipe joint comprises a joint body 4 and a ferrule 2 positioned at an opening of the joint body 4, wherein the ferrule 2 is fixed outside the opening of the joint body 4 through a nut 3; a stop block 5 is arranged inside the joint body, a thread structure matched with an inner hole of the joint body 4 is arranged on the excircle of the stop block 5, and the position of the stop block 5 can be adjusted forwards and backwards inside the joint body 4 through threads;
preferably, the stop block is provided with a tool groove, so that a screwdriver and other tools can be conveniently used for adjusting the position of the stop block;
the specific working principle is as follows:
the utility model discloses a conventional coupling the inside adds the dog, can the fore-and-aft regulation dog position, and the device is by the joint body, the steel pipe, the nut, the cutting ferrule, the dog is constituteed, and the dog connects the body with screw thread screw in, can the fore-and-aft regulation length, according to the appropriate position of the length adjustment dog of steel pipe. The steel pipe plane saw is vertical and has no burr. The nut and the ferrule are mounted on the steel tube in the correct orientation. The steel pipe with the nut and the clamping sleeve is arranged in the joint body, the steel pipe is compressed, the plane of the steel pipe is ensured to be in contact with the stop block, and the two end faces are parallel and level.
(stop moving back and forth to the appropriate position)
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
