Abstract
The invention discloses a hydraulic rod top locking device and relates to the technical field of hydraulic assemblies. The hydraulic rod top locking device mainly comprises a hydraulic rod body and is characterized in that outer threads are arranged at the front end of the hydraulic rod body, a connecting rod provided with a threaded hole is screwed on the outer threads, the front end of the connecting rod is provided with a locking ring, the threaded hole in the connecting rod penetrates through the locking ring, and the length of the outer threads at the front end of the hydraulic rod body is larger than the sum of the diameter of the connecting rod and the diameter of the locking ring. The hydraulic rod top locking device is simple in structure and reasonable in design, the connecting rod is connected to the hydraulic rod body in a threaded mode, the length of the portion, screwed on the connecting rod, of the hydraulic rod body is controlled, so that the orientation of the hole of the locking ring can be controlled, the hydraulic rod top locking device can be adapted to different connecting directions, and the range of application is wide; after the outer threads penetrate through the locking ring, the function of fastening connection is achieved, so that connection is more stable and the hydraulic rod top locking device is not prone to loosening and falling off.
Description
Technical field:
The present invention relates to the hydraulic package technical field, be specifically related to a kind of hydraulic rod top 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 constitutionally stable hydraulic rod top locking device is provided.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of hydraulic rod top locking device, mainly comprise the hydraulic rod main body, it is characterized in that: described hydraulic rod body front end is provided with outside thread, on outside thread, spiral has the connecting rod that is threaded hole, the connecting rod front end is provided with locking ring, tapped hole on described connecting rod is got through locking ring, and the external thread length of described hydraulic rod body front end is greater than the overall length of connecting rod and locking ring diameter.
Described hydraulic rod body front end cuts one deck annulus, the hydraulic rod body front end is formed stepped, and outside thread is located at by on tangent plane.
Described connecting rod spiral is on outside thread, and connecting rod outer side wall and hydraulic rod main body outer side wall coincide.
Described outside thread is provided with rubber washer.
The present invention is simple in structure, reasonable in design, the connecting rod spiral is connected on hydraulic rod, control the length of hydraulic rod spiral at connecting rod, the position, hole that can control locking ring towards, more adapt to different connection orientations, applied widely, and outside thread can play the effect that is fastenedly connected after passing locking ring, makes connection more stable, is difficult for becoming flexible, coming off.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Wherein: 1: the hydraulic rod main body; 2: outside thread; 3: connecting rod; 4: locking ring; 5: rubber washer.
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 top locking device as shown in Figure 1, mainly comprise hydraulic rod main body 1, hydraulic rod main body 1 front end is provided with outside thread 2, on outside thread 2, spiral has the connecting rod 3 that is threaded hole, connecting rod 3 front ends are provided with locking ring 4, wherein the tapped hole on connecting rod 3 is got through locking ring 4, wherein the external thread length of hydraulic rod main body 1 front end is greater than the overall length of connecting rod 3 with locking ring 4 diameters, hydraulic rod main body 1 front end cuts one deck annulus, make hydraulic rod main body 1 front end form stepped, outside thread 2 is located at by on tangent plane, connecting rod 3 spirals are on outside thread 2, connecting rod 3 outer side walls and hydraulic rod main body 1 outer side wall coincide, wherein outside thread 2 is provided with rubber washer 5.
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.
