Abstract

The invention provides a hydraulic rod locking device, which relates to the field of hydraulic pressure and mainly comprises a hydraulic rod main body, wherein the top end of the hydraulic rod main body is provided with a locking ring. The hydraulic rod locking device is characterized in that an annular groove is arranged in the locking ring, an arc pressure block is arranged in the annular groove, the arc is an inferior arc, the side face of the locking ring is provided with a threaded hole, a fastening screw is arranged in the threaded hole, the threaded hole is communicated with the annular groove, and a steel ball is arranged in the threaded hole. The hydraulic rod locking device has the beneficial effects that the structure is simple, the design is reasonable, the fastening screw is used for jacking the steel ball, the steel ball is abutted against the arc pressure block, and the arc pressure block is used for extruding a connecting rod arranged in the locking ring in a penetrating manner, and fastening the connecting rod by extrusion, so that the stability is enhanced, and rubdown of the front end of the fastening screw caused by the fact that the fastening screw directly extrudes the arc pressure block can be avoided by extrusion of the steel ball, the steel ball is convenient to replace, and the hydraulic rod locking device is simple and practical.

Description

A kind of hydraulic rod locking device
Technical field:
The present invention relates to Hydraulic Field, be specifically related to a kind of hydraulic rod locking device.
Background technique:
Existing hydraulic rod all will be subject to the pressure of larger intensity and keep the stability of operation at running hours, thus the group of its supporting component connect need be more firm, be difficult for becoming flexible, come off otherwise can affect to a certain extent working efficiency.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defect of prior art, and a kind of high, firm hydraulic rod locking device of intensity of locking is provided.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of hydraulic rod locking device, mainly comprise the hydraulic rod main body, hydraulic rod main body top is provided with locking ring, it is characterized in that: be provided with annular groove in described locking ring, be provided with the circular arc briquetting in annular groove, described circular arc is minor arc, described locking ring side is provided with tapped hole, be provided with a fastening screw trip bolt in tapped hole, tapped hole communicates with annular groove, is provided with a steel ball in described tapped hole.
On the screw thread hole wall at described steel ball place, spiral has one with externally threaded annulus cover.
Described circular arc briquetting is provided with anti-slip veins.
The present invention is simple in structure, reasonable in design, utilize fastening screw trip bolt fore-set steel ball, steel ball withstands on the circular arc briquetting, and the extruding of circular arc briquetting is through on the interior connecting rod of locking ring, by extruding, is fastenedly connected bar, strengthen steadiness, steel ball extruding can be avoided fastening screw trip bolt directly to push the fastening screw trip bolt front end that the circular arc briquetting causes polishing, change steel ball convenient, and is simple and practical.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Wherein: 1: the hydraulic rod main body; 2: locking ring; 3: annular groove; 4: the circular arc briquetting; 5: anti-slip veins; 6: tapped hole; 7: fastening screw trip bolt; 8: steel ball; 9: the annulus cover.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand,, below in conjunction with concrete diagram, further set forth the present invention.
A kind of hydraulic rod locking device as shown in Figure 1, mainly comprise hydraulic rod main body 1, hydraulic rod main body 1 top is provided with locking ring 2, be provided with annular groove 3 in locking ring 2, be provided with circular arc briquetting 4 in annular groove 3, circular arc is minor arc, circular arc briquetting 4 is provided with anti-slip veins 5, wherein locking ring 2 sides are provided with tapped hole 6, be provided with a fastening screw trip bolt 7 in tapped hole 6, tapped hole 7 communicates with annular groove 3, is provided with a steel ball 8 in tapped hole 6, and on tapped hole 6 walls at steel ball 8 places, spiral has one with externally threaded annulus cover 9.
Above demonstration and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
