Abstract
The utility model discloses a kind of self-locking manual hydraulic lifting valve, including handle；It is provided with self-locking mechanism on described handle；Described self-locking mechanism includes: self-locking handle, limit fastener, elastomeric element and elastomeric element limiting plate；Described self-locking handle is socketed on described handle, described self-locking handle and described limit fastener clamping；Described elastomeric element is socketed on described handle, and is positioned at inside described self-locking handle；Described elastomeric element limiting plate is arranged on described elastomeric element top.The present embodiment adds a self-locking mechanism on hand-hydraulic lifting valve, makes hand-hydraulic lifting valve have auto-lock function middle position when, even if people encounters hand-hydraulic lifting valve by mistake, also will not operate hydraulic system.
Description
Technical field
This utility model relates to dumping car hydraulic lifting valve, is specifically related to a kind of self-locking manual hydraulic lifting valve.
Background technology
Dumper all has a hand-hydraulic lifting valve at driver's cabin, is normally between two seats, drives
Member is when driving, when operating gear, it is possible to can encounter hand-hydraulic lifting valve, due to hydraulic lifting valve
It is to realize bit function in return and holding, after people encounters hand-hydraulic lifting valve, hydraulic pressure system by spring
System then can start working, thus unintentionally can cargo box hoisting, cause great potential safety hazard under steam.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of self-locking manual hydraulic lifting valve.
For solving above-mentioned technical problem, this utility model by the following technical solutions:
A kind of self-locking manual hydraulic lifting valve, including handle；It is provided with self-locking mechanism on described handle；
Described self-locking mechanism includes: self-locking handle, limit fastener, elastomeric element and elastomeric element limiting plate；Institute
State self-locking handle to be socketed on described handle, described self-locking handle and described limit fastener clamping；Described elasticity
Parts are socketed on described handle, and are positioned at inside described self-locking handle；Described elastomeric element limiting plate is arranged
At described elastomeric element top.
Further technical scheme is that described self-locking handle top is provided with self-locking handle cap.
Further technical scheme be described elastomeric element be spring.
Compared with prior art, one of beneficial effect of this utility model embodiment is: the present embodiment is manually
Add a self-locking mechanism on hydraulic lifting valve, make hand-hydraulic lifting valve have auto-lock function middle position when,
Even if people encounters hand-hydraulic lifting valve by mistake, also will not operate hydraulic system.
