Description
Technical field
The utility model belongs to auto parts machinery field.
Background technique
Hydraulic jack Application comparison is popularized, and hydraulic energy is changed into mechanical energy, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).Its structure is simple, reliable operation.When realizing to-and-fro motion with it, can speed reducer be removed from, and there is no drive gap, stable movement, therefore be used widely in the hydraulic system of various machinery.But, hydraulic jack instantaneous stressed time, power cannot be consumed at once, very easily cause danger.
Summary of the invention
The purpose of this utility model be can hydraulic jack instantaneous stressed time, be unlikely to cause dangerous routed cylinder of stretching to burst and stretch structure.
U of the present utility model presss from both sides inside left chamber and right chamber, and left chamber and right chamber are communicated by locking groove,
Left side: have guide piston in left chamber, the guide rod of guide piston front end is inserted in passage, and guide piston rear end is inserted in left plug screw, and left plug screw is inserted in left chamber by screw thread;
Right side: be inserted with right plug screw by screw thread in right chamber, right plug screw front end is pressure regulation plug screw, is provided with spring between pressure regulation plug screw and push rod, and sealing steel ball is placed on the left of passage and between push rod;
Burst and stretch lockable mechanism: on the sidewall of guide piston, have locking groove; The U folder that guide piston sidewall is corresponding has locking hole, and locking hole internal thread is provided with locking plug screw, by extrusion spring jack-up locking steel ball above locking plug screw.
The groove corresponding with sealing steel ball with the position of push rod grip seal steel ball on the left of passage of the present utility model.
The surface of contact that guide piston sidewall of the present utility model and U press from both sides left chamber surface of contact, guide piston inserts left plug screw is all sealed by O RunddichtringO.
The utility model structure is simple, and when oil hydraulic cylinder is subject to instantaneous external force, playing bursts stretches effect, the safety of protection occupant.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
U of the present utility model presss from both sides 10 inside left chamber 2 and right chamber 11, and left chamber 2 and right chamber 11 are communicated by locking groove 13,
Left side: have guide piston 4 in left chamber 2, the guide rod 5 of guide piston 4 front end is inserted in passage 13, and guide piston 4 rear end is inserted in left plug screw 1, and left plug screw 1 is inserted in left chamber 2 by screw thread;
Right side: be inserted with right plug screw 9 by screw thread in right chamber 11, right plug screw 9 front end is pressure regulation plug screw 8, is provided with spring 12 between pressure regulation plug screw 8 and push rod 7, sealing steel ball 6 is placed on the left of passage 13 and between push rod 7;
Burst and stretch lockable mechanism: on the sidewall of guide piston 4, have locking groove 3; The U folder 10 that guide piston 4 sidewall is corresponding has locking hole 14, and locking hole 14 internal thread is provided with locking plug screw 17, and locking plug screw 17 is above by extrusion spring 16 jack-up locking steel ball 15.
Grooves corresponding with sealing steel ball 6 with the position of push rod 7 grip seal steel ball 6 on the left of passage 13 of the present utility model.
The surface of contact that guide piston 4 sidewall of the present utility model and U press from both sides 10 left chamber surface of contact, guide piston 4 inserts left plug screw 1 is all sealed by O RunddichtringO.
Below in conjunction with accompanying drawing, the utility model is described in detail:
one, connect:
Left side: O type circle and be contained on guide piston, is contained in the rising oil circuit side of U folder, bursts in the directed cavity of extending portion position, plays sealing, leading role.To press from both sides with U outside guide piston and plug screw and gasket seal play seal action.
Burst and stretch lockable mechanism: lock steel ball and be contained in lock chamber, communicate with the locking groove of guide piston.Locking steel ball is connected with plug screw by spring, plays sealing, precompressed effect.
Right side: sealing steel ball is connected with the sealing surface that U presss from both sides.Outside is connected with pressure regulation plug screw by push rod, spring, plays sealing, pressure regulation effect.Plug screw and pad and U press from both sides and play seal action by scyewed joint.
two, burst stretch effect working principle:
Oil cylinder is (within 0.2 second) at short notice, when being subject to powerful external broach.Hydraulic oil has entered to burst by oil circuit to be stretched in the one-way valve of effect.Hydraulic oil acts on the left side of guide piston, and promote guide piston and move right, guide piston backs down sealing steel ball.Sealing steel ball drives push rod to move right.Spring is compressed.Meanwhile, locking steel ball, under the effect of loaded spring, enters in the lock groove of guide piston.Guide piston locking, whole mechanism can not move.
Now, oil hydraulic cylinder epicoele and cavity of resorption communicate.Epicoele hydraulic oil, through decline oil circuit, by oil circuit, enters into epicoele oil circuit.And entered in the lower oil cavitie of oil hydraulic cylinder by epicoele oil circuit.
