Abstract
The utility model relates to a connecting structure of a hydraulic cylinder end. A guide sleeve and a piston rod are installed in a cylinder body, and a piston and a locknut are installed at the end part of the piston rod; and the guide sleeve is provided with a sealing groove and a guide tape groove; a piston rod seal ring, a piston rod combination seal ring and a seal ring are installed in the sealing groove of the guide sleeve, a guide tape is installed in the guide tape groove of the guide sleeve, a guide tape is installed in a guide tape groove of the piston, a piston combination seal ring and a seal ring are installed in the sealing groove of the piston, a gland is connected with the cylinder body via threads so as to axially compact the guide sleeve, and a lock screw is installed on the cylinder body. The connecting structure has the advantages that the guide sleeve and the guide tape are combined to guide the piston rod, and the cylinder end part is sealed through the combination with sealing elements; and the sealing elements in the grooves can not be damaged or broken by twisting. When the gland is screwed in, no other additional friction force exists, and time and labor can be saved during installation. The connecting structure has strong assembly performance, the assembly difficulty of a hydraulic cylinder is reduced, the assembly and disassembly efficiency of the hydraulic cylinder is increased, and the structure is safe and reliable and has good locking effect.
Description
Technical field
The utility model is used the linkage structure that the cylinder head internal thread connects a kind of hydraulic jack cylinder head of oil hydraulic cylinder.
Background technique
At present; The targeting part and the attachment portion of the hydraulic jack cylinder head that the cylinder head internal thread of selling on the market connects are made of one the formula structure mostly; This structure when hydraulic jack assembling or dismounting maintenance because each Sealing function of friction; Screw thread is difficult for revolving usefulness during assembling, and screw thread be difficult for to screw out during laid-up, and along with the screw-in of cylinder head or screw out each Sealing have because of rotation sprain even damage maybe.
Summary of the invention
The utility model purpose is to solve above-mentioned existing existing problem, provides a kind of loading, unloading efficient high, and the linkage structure of the hydraulic jack cylinder head that Sealing is sprained or damaged when reducing loading, unloading.
The utility model is achieved in that installs guide sleeve, piston rod in cylinder body, piston, locking nut are installed in the end of piston rod; Guide sleeve has sealed groove, guidance tape groove; Rod seal circle, piston rod combined seal ring, seal ring are installed in the sealed groove of guide sleeve; Guidance tape is installed in the guidance tape groove of guide sleeve; Guidance tape is installed in the guidance tape groove of piston, piston in combination seal ring, seal ring are installed in the sealed groove of piston, gland is connected with cylinder body through screw thread and makes the guide sleeve axial compression; Lock screw is installed on cylinder body, and is regulated elasticity through lock screw.
The utility model has the advantages that guide sleeve is the synthesis of collection sealed groove, a guidance tape groove, through can leading to piston rod with the guidance tape combination, through with can partly seal cylinder head with seal combination.With Sealing and the guidance tape groove of packing into earlier, again this integral body is directly axially pushed cylinder body afterwards during installation, need not the rotation of wide-angle, so bad phenomenon can not appear spraining or turning round in the Sealing in the groove.Gland is an externally threaded structure of covering, and its effect mainly is after guide sleeve integral body pushes cylinder body, through the screw-in of screw thread, with the guide sleeve axial compression, prevents the guide sleeve axial float, and loosens through marking closely screw.The gland of this structure does not have other additional frictional force when being threaded into, so can be time saving and energy saving during installation; Assembly process process is strong, reduced such hydraulic jack assembling difficulty, and improve the hydraulic jack mounting or dismounting and unloaded efficient, and through facts have proved that this structural safety is reliable, anti-loosing effect is good.
