Embodiment 1

[0044] Such as Figure 1~6 As shown, this product is a high-sensitivity dynamic expansion oil pipe connector, including a connecting part, a driving part, and a sealing part;

[0045] The connecting part includes a joint body, an equipment connector 1 is arranged at one end of the joint body, and an oil pipe connector is arranged at the other end of the joint body, and the oil pipe connector includes a fixed surface for contacting the inner wall of the oil pipe;

[0046]The drive part includes a drive block 7 and a push ring 10 arranged on the inner wall of the oil pipe connector. The drive block 7 is a hollow cylinder, and a number of protruding keys 8 are arranged in an annular array on the outer wall of the drive block 7. The protruding The axis of the key 8 is parallel to the axis of the drive block 7, and a push key 9 is also arranged on the top of the raised key 8. The upper surface of the push key 9 is an inclined plane, and the push ring 10 is connected to the drive b...

Abstract

The invention relates to a high-sensitivity dynamic expansion oil pipe joint which mainly comprises an oil pipe joint body and a driving block arranged in the oil pipe joint body, wherein the driving block is provided with a plurality of push keys protruded from the wall surface of the oil pipe joint body; the push keys are internally provided with helical fins used for bearing pressure, and the surfaces of the push keys are inclined surfaces. When oil pressure is increased, the push keys move, and can drive a rubber ring wrapping the outer wall of the oil pipe joint body to expand in the process of moving, so that the binding force of the oil pipe joint and the wall surface of an oil pipe is increased.

Description

technical field [0001] The invention relates to a high-sensitivity dynamic expansion oil pipe joint, which belongs to the field of oil supply pipe joints of hydraulic equipment. Background technique [0002] With the rapid development of industry and more and more large-scale equipment, hydraulic pressure is widely used in many driving or load-bearing fields; first of all, in the field of construction, in order to reduce the impact of construction sites on the local environment ( For example, the dust brought by cement powder), now it is generally used to make prefabricated parts outside the construction site, and then move them to the construction site for assembly by large machinery; moreover, in the mining industry, the demand for coal mines and stone materials is also increasing. The traditional small-scale excavation machinery can no longer meet the current demand. Although the local production and construction of related equipment can save costs, it will greatly prolon...
