Abstract
The invention relates to a one-way valve of an excavator tensioning device. The one-way valve comprises a valve body, a valve rod and pins. The one-way valve is characterized in that a valve rod hole and pin holes are formed in one end of the valve body, the valve rod is provided with a groove, the valve rod is placed in the valve rod hole of the valve body, the pins penetrate the pin holes of the valve body, and the groove of the valve rod is clamped. Compared with the prior art, the one-way valve has the beneficial effects that the structure is simple, operation is convenient, disengaging is prevented, and the valve rod can freely rotate.
Description
Technical field
The invention belongs to excavator accessory, especially a kind of one-way valve of excavator tensioning apparatus.
Background technique
The one-way valve of existing excavator tensioning apparatus, its valve rod uses nut to block, and prevents from, and when valve rod needs to rotate, nut be unscrewed, need fastening nut when valve rod rotate in place.Such operation is particularly troublesome, uses inconvenience.
Summary of the invention
The one-way valve of the excavator tensioning apparatus that the object of the present invention is to provide a kind of structure simple, easy to operate.
Technological scheme adopted to achieve the object of the present invention is as follows:
1, an one-way valve for excavator tensioning apparatus, comprises valve body, valve rod, pin, it is characterized in that, described valve body one end is provided with valve rod hole and pin hole, described valve rod is provided with groove, and valve rod is placed in the valve rod hole of valve body, and blocks the groove of valve rod through the pin hole of valve body with pin.
The present invention compared with prior art, has structure simple, easy to operate, prevents from, and valve rod such as freely can to rotate at the advantage.
Accompanying drawing illustrates:
Fig. 1 is overall structure front sectional view of the present invention.
In FIG, valve body (1), pin (2), valve rod (3).
embodiment:
Describe the present invention below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of one-way valve of excavator tensioning apparatus, comprise valve body, valve rod, pin, wherein, described valve body 1 one end is provided with valve rod hole and pin hole, and described valve rod 3 is provided with groove, valve rod 3 is placed in the valve rod hole of valve body 1, and the groove of valve rod 3 is blocked with the pin hole that pin 2 passes valve body 1, prevent from, and valve rod 3 can freely rotate.
The beneficial effect of this embodiment: structure is simple, easy to operate, prevent from, and valve rod can freely rotate.
