Abstract
The utility model provides a bolt jar regulator, including piston main part, adjusting collar and connecting rod, the one end of piston main part is fixed with the connecting rod, and the central point of the other end puts has the screw hole, and the one end of adjusting collar be the blind end, and the other end is open end, and the internal surface center department of blind end has a screw thread guide regulation pole, and the one end of screw thread guide regulation pole is stretched out the open of adjusting collar and is held, and in one end that the piston main part has a screw hole can stretch into the adjusting collar, at this moment, screw thread guide regulation pole can stretch into in the screw hole. The beneficial effects of the utility model are that utilize mechanical structure to carry out the pressure adjustment to the bolt jar to change the stroke of piston rod, its cost of manufacture is less than automatically controlled regulation, and the fault rate is low, maintains simple and conveniently.
Description
Technical field
This utility model relates to a kind of latch cylinder regulator.
Background technology
In existing technology, latch cylinder is that the head of a kind of piston rod is equipped with telescopic latch, flexible by latch makes piston rod can connect from different operating mechanisms as required or depart from, thus realizing an oil cylinder to drive the purpose of multiple operating mechanisms, the pressure of regulating pin cylinder inner fluid can control the stroke of piston rod, usual way is the flow that the size utilizing electromagnetic valve to open controls fluid, thus reaching to control the purpose of piston rod stroke, during defect, the cost of manufacture of circuit control mode is higher, and fault rate and maintenance cost are high.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of latch cylinder regulator, overcomes deficiency of the prior art.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: latch cylinder regulator, including piston main body, regulate set and connecting rod, one end of described piston main body and described connecting rod are fixed, the center of the other end has screwed hole, described one end regulating set is blind end, the other end is open end, the inner surface center of described blind end has screw thread guiding adjusting rod, the described open end regulating set is stretched out in one end of described screw thread guiding adjusting rod, described piston main body has one end of described screwed hole and can stretch in described adjustment set, now, described screw thread guiding adjusting rod can stretch in described screwed hole.
Further, also include sealing ring and sealing ring cap, the described medial surface regulating set has land near open end place it described, described sealing ring is positioned in described land, the described outer surface regulating set has external screw thread by its described open end place, having the female thread adaptive with described external screw thread on the medial wall of described sealing ring cap, described sealing ring cap can be combined on described adjustment and put, thus reaching the purpose sealed.
This utility model has the advantage that and has the benefit effect that owing to adopting technique scheme, and utilizing frame for movement that latch cylinder is carried out pressure adjustment, thus changing the stroke of piston rod, its cost of manufacture is lower than automatically controlled adjustment, failure rate is low, convenience easy to maintenance.

Detailed description of the invention
As shown in Figure 1, this utility model provides a kind of latch cylinder regulator, including piston main body 1, regulate set 3 and connecting rod 2, one end of piston main body 1 is fixed with connecting rod 2, the center of the other end has screwed hole, the one end regulating set 3 is blind end, the other end is open end, the inner surface center of blind end has screw thread guiding adjusting rod 6, the open end regulating set 3 is stretched out in one end of screw thread guiding adjusting rod 6, piston main body 1 has one end of screwed hole and can stretch in adjustment set 3, and now, screw thread guiding adjusting rod 6 can stretch in screwed hole.
By rotary-piston main body 1 so as to the direction of the adjusting rod 6 that threadingly leads is moved, so that piston main body 1 stretches out the volume regulating set 3 and changes, so that the ratio that whole piston accounts for cylinder inner volume changes, so under the constant premise of flow, oil pressure in cylinder just there occurs change, thus reaching to regulate the purpose of connecting rod 2 stroke.
Also include sealing ring 5 and sealing ring cap 8, the medial surface regulating set 3 has land 4 near its open end place, sealing ring 5 is positioned in land 4, the outer surface regulating set 3 has external screw thread 7 by its open end place, having on the medial wall of sealing ring cap 8 and the female thread of external screw thread 7 adaptation, sealing ring cap 8 can be combined on adjustment set 3, thus reaching the purpose sealed, avoid fluid to leak in adjustment set 3, affect the adjustment of pressure.
Above embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All equalizations made according to this utility model application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
