Description
Technical field
A kind of attachment structure is the utility model is related to, more particularly to the attachment structure of a kind of valve rod and piston rod.
Background technology
In the prior art, when existing valve rod is connected with hydraulic cylinder piston rod by Hough connector, inside Hough connector
Shoulder hole is set, and epicoele is used to embed valve rod, and in the cavity of resorption of Hough connector, valve rod is with piston rod by flange come the company of fixation
Connect, installing/dismounting is more troublesome.
The content of the invention
In order to overcome the shortcomings of in background technology, the utility model is provided with right-angled trapezium using Hough connector upper and lower ends
Spacing block set, valve rod on piston rod with being respectively equipped with right-angled trapezium stopper slot, with the right-angled trapezium limit convex on Hough connector
The spacing cooperation of block, instead of flange, simplifies structure.
A kind of attachment structure of valve rod and piston rod, including valve rod, piston rod and Hough connector, the Hough connector
It is divided into the left valve of Hough connector and the right valve of Hough connector, the junction of the left valve of Hough connector and the right valve of Hough connector passes through
Bolt connection is fixed, and the valve rod head connects with piston rod head, and valve rod head is located at Hough with piston rod head joint
Connector center, Hough connector upper and lower ends are provided with right-angled trapezium spacing block set, and valve rod on piston rod with being respectively equipped with right angle
The spacing cooperation of right-angled trapezium spacing block set on trapezoidal stopper slot, with Hough connector.
The Hough connector inner chamber is circular groove.
The stem diameter is identical with diameter of piston rod.
The bolt quantity is 8.
The beneficial effects of the utility model are：The attachment structure of valve rod and piston rod is simplified, is replaced using position limiting structure
Flange, makes the installing/dismounting more convenient.
Brief description of the drawings
Fig. 1 is the structural representation of the attachment structure of the utility model embodiment valve rod and piston rod.
Fig. 2 is the structural representation of the attachment structure of the utility model embodiment valve rod and piston rod.
Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As illustrated, the attachment structure of a kind of valve rod and piston rod, including valve rod 1, piston rod 3, and Hough connector 2,
The Hough connector 2 divides to be connected for the left valve 6 of Hough connector and the right valve 7 of Hough connector, the left valve 6 of Hough connector with Hough
The junction of the right valve 7 of part is bolted fixation, and the head of valve rod 1 connects with the head of piston rod 3, the head of valve rod 1 and piston rod 3
Head joint is located at Hough connector center, and the upper and lower ends of Hough connector 2 are provided with right-angled trapezium spacing block set 21, valve rod 1
With being respectively equipped with right-angled trapezium stopper slot 22 on piston rod 3 and the right-angled trapezium spacing block set 21 on Hough connector 2 is spacing matches somebody with somebody
Close, the bolt connection is that the left valve 6 of Hough connector valve 7 right with Hough connector is fixedly connected by stud 4, nut 5.
Utilize the right-angled trapezium stopper slot 22 on valve rod 1 and piston rod 3 and the right-angled trapezium limit convex on Hough connector
The spacing cooperation of block 21, instead of flange, simplify structure, and the wherein a line of right-angled trapezium is hypotenuse, be easy to during installation by
In projection insertion groove, installation is more convenient.
As illustrated, the inner chamber of Hough connector 2 is circular groove, the inner chamber of Hough connector 2 is set to circular groove,
It is easy to be adapted with valve rod 1 and piston rod 3, is easily installed.
The diameter of valve rod 1 is identical with the diameter of piston rod 3, by above-mentioned setting, is easy to the processing of the inner chamber of Hough connector 2
With the setting of spacing block set 21 and the stopper slot being adapted 22.
The bolt quantity is 8, and the effect that is connected is more preferable.
Every technical staff's notice：Although the utility model describes according to above-mentioned embodiment, this
The invention thought of utility model is not limited to that utility model, any repacking with inventive concept, will all include this specially
In sharp scope of patent protection.
