Description
Technical field
The present invention relates to elevating ram, more particularly to Explosion proof joint component and its elevating ram.
Background technology
As automobile market is to the more and more higher of quality and the security performance requirement of each parts, particularly with those safety
Part is more harsh.The safety member that hydraulic cab elevating ram used by commercial car belongs in chassis member need also exist for by
Especially pay attention to, must both ensure lifting/decline during can efficient operation and secure ratcs, ensure surprisingly to be burst in oil circuit again
Driver's cabin not rapid decrease is also ensured that after decompression, to avoid the injury to personnel.The tool for being used for middle heavy truck at present
There is the ram cylinder of unidirectional locking function, locking of the oil cylinder in any position can be can guarantee that substantially, but it is light for the overwhelming majority
The heavy truck of card and minority uses ram cylinder, and latch functions are not designed with inside it, once oil line pipe bursts, then
In the presence of driver's cabin load, oil cylinder will quickly glide, it is easy to cause security incident.And setting for light/middle card itself
Meter using complex structure and ram cylinder on the high side and is not applied in accordance with low-cost high-efficiency energy principle, and
The fault rate of ram cylinder also above plunger type oil cylinder, operability do not have the convenient of plunger type yet.
The content of the invention
The present invention is for the unsafe shortcoming of elevating ram in the prior art, there is provided Explosion proof joint component and its lifting oil
Cylinder.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：
