Drawings

Fig. 1 is a schematic structural diagram of a jack with a locking mechanism according to the present invention;

fig. 2 is an enlarged view of a structure at a position a of the jack with the locking mechanism provided by the present invention.

In the figure: the device comprises a base 1, a fixed cavity 2, a control cavity 3, a hydraulic cylinder 4, a piston plate 5, a top plate 6, a soft cushion 7, a support rod 8, a movable plate 9, a buffer block 10, a connecting pipe 11, an exhaust pipe 12 and an air inlet pipe 13.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a jack with locking mechanical system, including base 1, base 1 is inside to be equipped with fixed chamber 2, the sealed sliding connection of 2 inner walls in fixed chamber has movable plate 9, a plurality of buffer blocks 10 of bottom fixedly connected with in fixed chamber 2, lateral wall all contacts with lateral wall under the movable plate 9 on a plurality of buffer blocks 10, the speed is direct to take place the striking and be impaired with 2 bottom plates in fixed chamber at the excessive speed when preventing movable plate 9 from falling, good cushioning effect has been played, the life of device has been prolonged, lateral wall fixedly connected with a plurality of bracing pieces 8 on the movable plate 9, the common fixedly connected with roof 6 in a plurality of bracing pieces 8 upper end, lateral wall fixedly connected with cushion 7 on roof 6, cushion 7 is made by rubber, it can prevent that the jack from and by the too big and impaired condition appearance of pressure between the lifting object to set up cushion 7.

Base 1 inside is equipped with the actuating mechanism who is used for driving roof 6 to shift up, actuating mechanism is including setting up at the inside control chamber 3 of base 1, top fixedly connected with pneumatic cylinder 4 in the control chamber 3, the flexible end fixedly connected with piston plate 5 of pneumatic cylinder 4, in order to guarantee that piston plate 5 can reciprocate smoothly, the upper end in control chamber 3 need be through pipeline and external intercommunication, 3 inner wall intercommunications in control chamber are equipped with intake pipe 13, be equipped with first check valve in the intake pipe 13, only allow the air to enter into control chamber 3 from the external world, 3 inner walls in control chamber pass through connecting pipe 11 and fixed chamber 2 intercommunication, be equipped with the second check valve on the connecting pipe 11, only allow the air to enter into fixed chamber 2 from
