When guide sleeve is specifically connected with cylinder barrel, the locating face of guide sleeve and fixing face are inserted in the nozzle of cylinder barrel, the first boss on guide sleeve is through the later rotary guide sleeve of the groove between adjacent two the second boss on cylinder barrel, now, top cover holding on guide sleeve is on the nozzle of cylinder barrel, locating face on guide sleeve and fixing face are assemblied in respectively in the locating slot and fixing slot on cylinder barrel, the mutual clamping interlock of the second boss on the first boss on guide sleeve and cylinder barrel is fixed, and finally realizes the connection of guide sleeve and cylinder barrel.The utility model structure can realize fast and reliable, time saving and energy saving connection, facilitate manufacturing, the maintenance maintenance of oil hydraulic cylinder product, eliminate the problem existing in scyewed joint pattern, to reaching the quality that has both guaranteed oil hydraulic cylinder product, can enhance productivity again and economic benefit.
Further, twist and to be provided with anti-loose positioning screwn at the top edge place of top cover, and the underpart of anti-loose positioning screwn is solid in the edge of cylinder barrel nozzle through twisting after top cover, further to strengthen location between guide sleeve and cylinder barrel, to tighten up.
The lid limit of top cover is provided with at least one pair of edge fixing for spanner, and the setting party of edge is convenient to the rotation of guide sleeve.
The beneficial effects of the utility model are:
1) guide sleeve and cylinder barrel connect adopt several to boss, overlap joint, small angle screw form up and down, convenient and swift, in the time of need not connecting as thread type, screw and can be seated several weeks.This connection form not only significantly reduces intensity and the difficulty of processing and assembling, repair demolition, has improved working efficiency, and while also thoroughly having eliminated guide sleeve and cylinder barrel employing scyewed joint, screw thread grinds the problems such as hurt is bad, assembling is wasted time and energy, maintenance maintenance difficulty;
2) the utility model for be the quick connection of oil hydraulic cylinder, especially to mining hydraulic cylinder when underground work, the withdrawal space are too narrow and small, the fast assembling-disassembling effect of the utility model structure is obvious especially;
3) the utility model is applicable to the connection of the oil hydraulic cylinder product of other types equally, applied widely.
