[0025] The drawings in the specification Figure 1 to the drawings Figure 4 It can be known that the compression device with stable lifting mainly comprises the following parts or components: support frame 10, lifting column 12, connection assembly.

[0026] The utility model discloses a support frame 10 below parallelly arranged has the compression frame 11, and the compression frame 11 is connected with support frame 10 through the lifting piece 40, and is lifted under the drive of lifting piece 40, a plurality of lifting columns 12 lower end are connected with compression frame 11 respectively, and the upper end is penetrated support frame 10 respectively, and the connecting assembly is set up on support frame 10, and is connected with a plurality of lifting columns 12, is used for assisting a plurality of lifting columns 12 synchronous lifting. The connecting assembly includes a plurality of first rotary shafts 21, and is arranged horizontally and rotatable on support frame 10, a plurality of first rotary shafts 21 are parallel with each other, a plurality of first gear wheels 22 are fixedly arranged on each first rotary shaft 21, a plurality of first gear wheels 22 correspond with a plurality of lifting columns 12 one to one, and the first gear wheel 22 is engaged with the rack 121 on the corresponding lifting column 12. Two adjacent first rotary shafts 21 are connected through transmission assembly. The transmission assembly includes a second rotary shaft 31, and is arranged horizontally and rotatable between two adjacent first rotary shafts 21, and the second rotary shaft 31 is perpendicular to the first rotary shaft 21, and two first bevel gears 32 fixedly arranged at the both ends of the second rotary shaft 31 are engaged with two second bevel gears 33 on two adjacent first rotary shafts 21 respectively.

[0027] When the first cylinder 41 works, compression frame 11 will be driven to move up and down. At the same time, the lifting of compression frame 11 will directly drive a plurality of lifting columns 12 to move up and down together, when the lifting column 12 rises or falls, the rack 121 will push the first gear wheel 22 engaged with it to rotate. And a plurality of first gear wheels 22 on one first rotary shaft 21 will rotate synchronously with the movement of the corresponding lifting column 12, when one first rotary shaft 21 rotates due to the movement of the lifting column 12 connected therewith, the second bevel gear 33 on the first rotary shaft 21 will drive the first bevel gear 32 engaged therewith to rotate, thereby driving the second rotary shaft 31 to rotate. The first bevel gear 32 at the other end of the second rotary shaft 31 will also drive the second bevel gear 33 on the adjacent first rotary shaft 21 to rotate, so that the adjacent first rotary shaft 21 also rotates. Since the first gear wheel 22 on each first rotary shaft 21 is engaged with the rack 121 on the corresponding lifting column 12, the synchronous rotation of each first rotary shaft 21 will drive the plurality of lifting columns 12 connected therewith to move up and down synchronously. In this way, even if a plurality of lifting columns 12 are at different positions, they can also be lifted smoothly under the action of the connecting assembly. In the case of using fewer cylinders, uniform pressure can also be applied to the product, improving the accuracy and reliability of the air tightness test.

[0028] As an embodiment, the utility model discloses a support frame 10 below parallelly arranged has the compression frame 11, and the compression frame 11 is connected with support frame 10 through the lifting piece 40, and is lifted under the drive of lifting piece 40, a plurality of lifting columns 12 lower end are connected with compression frame 11 respectively, and the upper end is penetrated support frame 10 respectively, and the connecting assembly is set up on support frame 10, and is connected with a plurality of lifting columns 12, is used for assisting a plurality of lifting columns 12 synchronous lifting. Figure 4It can be known that the support frame 10 is provided with a self-locking assembly 50, and the self-locking assembly 50 is used for limiting the cylinder joint 42. The self-locking assembly 50 comprises a second cylinder 51 which is horizontally arranged on the lower surface of the support frame 10 and is perpendicular to the first cylinder 41, and the second cylinder 51 is provided with a second connecting joint 52 at the end of the piston rod, and the second connecting joint 52 is provided with a plug rod 53 at the end, and the plug rod 53 is matched with the plug hole (not shown in the figure) arranged on the cylinder joint 42.

[0029] The piston rod of the first cylinder 41 is retracted, the pressing frame 11 is lifted through the first connecting joint 411 and the cylinder joint 42, and the pressing frame 11 is lifted until the plug hole on the cylinder joint 42 is coaxial with the plug rod 53 in the self-locking assembly 50, and then the piston rod of the second cylinder 51 is elongated, the plug rod 53 is driven to advance through the second connecting joint 52, and the plug rod 53 is inserted into the plug hole, so that the pressing frame 11 can be effectively limited and prevented from falling suddenly, when the limiting needs to be released, the piston rod of the second cylinder 51 is retracted, the plug rod 53 is retracted through the second connecting joint 52, and the plug rod 53 is separated from the plug hole.

[0030] Specifically, the plug hole can be a circular through hole or a long slot hole, and the circular through hole is preferred, if the long slot hole is used, the plug rod 53 is in contact with the upper end of the long slot hole after being inserted into the long slot hole.

[0031] As an embodiment, the self-locking assembly 50 is shown in the drawings of the specification. Figure 3 It can be known that the upper ends of the two adjacent lifting columns 12 are connected through the connecting rod 14, the support frame 10 below the connecting rod 14 is provided with the buffer rod 13, and the bottom of the buffer rod 13 is provided with the rubber pad 131.

[0032] The utility model provides a kind of stable lifting pressing device, when using, specific operation process is as follows:

[0033] When the first cylinder 41 works, the pressing frame 11 is driven to move up and down. At the same time, the movement of the pressing frame 11 directly drives the plurality of lifting columns 12 to move up and down. When the lifting column 12 rises or falls, the rack 121 drives the first gear 22 engaged therewith to rotate. The plurality of first gears 22 on one first rotating shaft 21 synchronously rotate with the movement of the corresponding lifting column 12. When one first rotating shaft 21 rotates due to the movement of the lifting column 12 connected therewith, the second bevel gear 33 on the first rotating shaft 21 drives the first bevel gear 32 engaged therewith to rotate, thereby driving the second rotating shaft 31 to rotate. The first bevel gear 32 on the other end of the second rotating shaft 31 drives the second bevel gear 33 on the adjacent first rotating shaft 21 to rotate, so that the adjacent first rotating shaft 21 also rotates. Since the first gear 22 on each first rotating shaft 21 is engaged with the rack 121 on the corresponding lifting column 12, the synchronous rotation of each first rotating shaft 21 drives the plurality of lifting columns 12 connected therewith to synchronously move up and down. In this way, even if the plurality of lifting columns 12 are at different positions, they can be stably lifted under the action of the connecting assembly. In the case of using fewer cylinders, uniform pressure can be applied to the product, thereby improving the accuracy and reliability of the air tightness test.
