Abstract
The invention discloses a connecting rod front end locking device and relates to the technical field of hydraulic assemblies. The connecting rod front end locking device mainly comprises a hydraulic rod body. The connecting rod front end locking device is characterized in that an external thread is arranged at the front end of the hydraulic rod body, a connecting rod with a threaded hole is screwed to the external thread, a locking ring is arranged at the front end of the connecting rod, the threaded hole in the connecting rod is communicated with the locking ring, and the length of the external thread at the front end of the hydraulic rod body is larger than the sum of the length of the connecting rod and the diameter of the locking ring. The connecting rod front end locking device is simple in structure and reasonable in design, the connecting rod is connected to the hydraulic rod in a screwed mode, the length of the part, screwed to the connecting rod, of the hydraulic rod is controlled, the hole orientation of the locking ring can be controlled, the connecting rod front end locking device adapts to different connecting directions better and is wide in application range, the external thread can play a role in fastening connection after penetrating out of the locking ring, connection can be more stable, and loosening and disengaging are not likely to occur.
Description
Technical field
the present invention relates to hydraulic package technical field, particularly relate to a kind of connecting rod front end locking device.
Background technique
the stability that the pressure keeping that existing hydraulic rod all will be subject to larger intensity at running hours runs, therefore the group of its supporting component connects and more firmly, not easily need loosen, come off otherwise can affect working efficiency to a certain extent.
Summary of the invention
technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of connecting rod front end locking device.
a kind of connecting rod front end locking device, mainly comprise 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 being threaded hole, connecting rod front end is provided with locking ring, tapped hole on described connecting rod gets 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.
further, described hydraulic rod body front end cuts one deck annulus, hydraulic rod body front end is formed stepped, and outside thread is located at by tangent plane.
again further, described connecting rod spiral is on outside thread, and connecting rod outer side wall and hydraulic rod main body outer side wall coincide.
further, described outside thread is provided with rubber washer.
advantage of the present invention:
structure of the present invention is simple, reasonable in design, connecting rod spiral is connected on hydraulic rod, hydraulic control bar spiral in the length of connecting rod, the position, hole that can control locking ring towards, more adapt to different connection orientations, applied widely, and outside thread can play through after locking ring the effect be fastenedly connected, make connection more stable, not easily loosen, come off.
Accompanying drawing explanation
below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
fig. 1 is structural representation of the present invention.In figure: 1, hydraulic rod main body; 2, outside thread; 3, connecting rod; 4, locking ring; 5, rubber washer.
Embodiment
the technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
a kind of connecting rod front end 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 being threaded hole, connecting rod 3 front end is provided with locking ring 4, tapped hole wherein on connecting rod 3 gets 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 and locking ring 4 diameter, hydraulic rod main body 1 front end cuts one deck annulus, hydraulic rod main body 1 front end is made to be formed stepped, outside thread 2 is located at by tangent plane, connecting rod 3 spiral is on outside thread 2, connecting rod 3 outer side wall and hydraulic rod main body 1 outer side wall coincide, wherein outside thread 2 is provided with rubber washer 5.
more than show and describe 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; what describe 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.Application claims protection domain is defined by appending claims and equivalent thereof.
