Abstract
The utility model discloses a looseness-proof device for a hydrocylinder. The looseness-proof device comprises a hydrocylinder cover, a hydrocylinder barrel, a fastening bolt and a piston rod, wherein the junction surface between the hydrocylinder cover and the hydrocylinder barrel is provided with the fastening bolt; and the piston rod passes through the hydrocylinder cover to extend into the hydrocylinder barrel. The looseness-proof device for the hydrocylinder has the advantages of simple structure, convenience for processing, low cost, reliable looseness-proof effect and very convenience for assembly and disassembly.
Description
Technical field
The utility model relates to a kind of locking locking device, specifically is a kind of oil cylinder cover locking device.
Background technique
Hydraulic jack commonly used in the engineering machinery is made up of cylinder barrel, cylinder cap, piston, piston rod and Sealing.Wherein, the Placement of cylinder tube and cylinder cap has a kind of be threaded (cylinder tube is an internal thread, and cylinder cap is an outside thread) that be.
Under the effect of pressure oil, being threaded between cylinder barrel and the cylinder cap might be taken place loosening and therefore situation that cause cylinder cap to come off, must be provided with a kind of locking device.
The model utility content
To the deficiency that above-mentioned similar technical problem exists, the purpose of the utility model provides a kind of oil cylinder cover locking device of simple and practical, convenient disassembly.
The technological scheme of the utility model is: a kind of oil cylinder cover locking device; Comprise oil cylinder cover, cylinder tube, Cock screw and piston rod; It is characterized in that: the junction plane place of oil cylinder cover and cylinder tube is equipped with a Cock screw, and piston rod passes oil cylinder cover and stretches in the cylinder tube.
The utility model has the advantages that: the utility model is simple in structure, easy to process, with low cost, anti-loosing effect reliable, installation and removal are all very convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Combine accompanying drawing at present, the technology contents of the utility model is described further.
As shown in Figure 1, oil cylinder cover 1 is equipped with a Cock screw 3 with the junction plane place of cylinder tube 2, and piston rod 4 passes oil cylinder cover 1 and stretches in the cylinder tube 2.
The principle of the utility model is: cylinder tube 2 is internal thread, and oil cylinder cover 1 is an outside thread, after oil cylinder cover 1 and cylinder tube 2 assemblings are tightened; At both junction plane places; Process an interior threaded hole, and a Cock screw 3 is installed, be coated with a little locking glue at Cock screw 3 places then.Under the effect of Cock screw 3, the screw thread between oil cylinder cover 1 and the cylinder tube 2 just can not become flexible.When oil cylinder needs repairing, only need unclamp Cock screw 3, just can open oil cylinder cover 1 easily and keep in repair.
