Abstract
The utility model discloses a central rotation joint, comprising a rotation body (1); an end portion of the rotation body (1) is connected with a connection body (2) by a bolt (5); a central shaft of the rotation body is provided with a rotation shaft (1.2), an end thereof is directly connected with an electro-hydraulic control valve to overcome some defects for connection of a pipeline; connection of two ends is in an axial direction so as to connect and assemble/disassemble conveniently; and a mounting space is reduced greatly, a design of entire system is optimized; because of specificity of products, a plurality of matched novel hydraulic fittings is arranged to make up blank inland.
Description
Technical field
The utility model relates to the hydraulic equipment field, and the spy relates to a kind of centre revolving joint that is used for the oil gas control mode fully.
Background technique
The application of centre revolving joint on equipment such as hoist, fire-fighting truck very extensively but because its leakage of oil, pulled phenomenon such as scuffing and produced frequently, uses to main frame and to have caused very big trouble.Along with the continuous expansion of product function, the improving constantly of automated procedures, to hydraulic element require increasingly highly, function is more complete, and the domestic centre revolving joint that does not also have can support to use two kinds of control modes of oil gas.
The model utility content
The purpose of the utility model is the technical problem that exists to existing technology, provide a kind of simple and compact for structure, with low cost, assembling is simple, a kind of centre revolving joint of good reliability.
The purpose of the utility model realizes as follows: a kind of centre revolving joint, comprise solid of rotation, and said solid of rotation end is connected through bolt with connecting body, and said solid of rotation central shaft is provided with turning axle.
Saying further, said turning axle edge is provided with a circle oil sealing, is positioned at said turning axle afterbody and is provided with baffle plate.
The advantage of the utility model: its end can directly link to each other with electro-hydraulic control valve, has reduced some defectives that pipeline connects; The connection at two ends is convenient to connect the convenience with dismounting all at axial direction; And installing space significantly reduces, and can optimize the design of whole system, because the particularity of this product, polygamy cover and new type hydraulic accessory can remedy domestic blank.
Description of drawings
For the content that makes the utility model is expressly understood more easily, below according to instantiation, and combine accompanying drawing that the present invention is done further detailed explanation, wherein:
Accompanying drawing is the structural representation of the utility model.
Embodiment:
See accompanying drawing, a kind of centre revolving joint comprises solid of rotation 1, and said solid of rotation 1 end is connected through bolt 5 with connecting body 2, and said solid of rotation central shaft is provided with turning axle 1.2; Said turning axle 1.2 edges are provided with a circle oil sealing 3, are positioned at said turning axle 1.2 afterbodys and are provided with baffle plate 4; Its working procedure is that said solid of rotation 1 one ends can directly link to each other with electro-hydraulic control valve because solid of rotation 1 is connected with connecting body 2, has reduced some defectives that pipeline connects, and the connection at two ends is convenient to connect the convenience with dismounting all at axial direction; And installing space significantly reduces.
Above-described instantiation; Purpose, technological scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the instantiation of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
