Abstract
Provided is a rapid oil cylinder. The rapid oil cylinder avoids leakage of the oil cylinder and improves reliability and safety. The rapid oil cylinder comprises a cylinder body and a blind flange, wherein the blind flange is arranged at the rear end of the cylinder body, external threads are arranged at one end of the blind flange, internal threads matched with the external threads of the blind flange are arranged at one end of the cylinder body, and the blind flange and the cylinder body are connected through the threads. The rapid oil cylinder is characterized in that the rapid oil cylinder further comprises a locking ring, and the locking ring is arranged at the end, with the external threads, of the blind flange in a sleeved mode and is located between the cylinder body and the blind flange. According to the rapid oil cylinder, the locking ring is arranged between the cylinder body and the blind flange, locking is achieved in the oil cylinder pressurization process, the problems of leakage, inconvenient maintenance and the like caused by the relative displacement generated by the failure of thread connection between the cylinder body and the blind flange are solved, and the stability, reliability and safety of the rapid oil cylinder in the working process are ensured.
Description
Technical field
The utility model relates to the improvement to Quick cylinder.
Background technique
The cylinder bottom blind flange of tradition oil cylinder is without locking mechanism, and cylinder bottom blind flange is directly connected by screw thread with cylinder body, as shown in Figure 2.Due to the existence of thread pitch, when after cylinder upper cavity oil pressurization, between cylinder bottom blind flange and cylinder body, produce relative displacement, 1), O shape circle damages and cause oil cylinder leakage of oil can cause following problem:; 2), the connected pipes bending of cylinder upper cavity oil and produce rupture and leakage.
Model utility content
The utility model, for above problem, provides one to avoid oil cylinder to reveal, and improves the Quick cylinder of reliability and Security.
The technical solution of the utility model is: comprise cylinder body and blind flange, described blind flange is arranged on the rear end of described cylinder body, one end of described blind flange is provided with outside thread, and one end of described cylinder body is provided with the internal thread suitable with the outside thread of described blind flange, is threaded connection between the two; It is characterized in that, also comprise locking ring, described locking ring is set in that described blind flange has externally threaded one end and between described cylinder body and blind flange.
Described locking ring is locking nut.
Also comprise pad, described pad is located between described locking nut and described cylinder body.
The anchor ring of the section of being threaded between described cylinder body and blind flange is provided with locating stud.
The anchor ring of the section of being threaded between described cylinder body and blind flange is provided with Cock screw.
The utility model has been set up locking ring between cylinder body and blind flange, locking in the time that oil cylinder pressurizes, avoid losing efficacy and producing the problem such as leakage, inconvenient maintenance that relative displacement causes because being threaded between cylinder body and blind flange, guaranteed stability, reliability and Security in fast cylinder working procedure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is structural representation of the prior art;
In figure, 1 is cylinder body, the 2nd, and blind flange, the 3rd, locking ring.
Embodiment
