Abstract
A kind of hydraulic lock, belongs to lock technology field.The purpose of this utility model is to provide a kind of latch hook body for entirety, and the hydraulic lock of amount of parts reduction.The utility model is made up of upper cover plate and lower cover, and upper cover plate and lower cover are symmetrical members, there is locking bolt neck in the middle of upper cover plate and lower cover；Latch hook body is arranged on pin, and pin two ends are separately fixed on upper cover plate and lower cover, and is rotated by axle of pin, hydraulic jack is provided with lower cover, the hydraulic push rod of hydraulic jack is withstood at the beaer on latch hook body；It is latch hook in latch hook body leading portion, hydraulic push rod return spring is cased with pin, latch hook body back-moving spring is placed between upper cover plate and lower cover.The utility model is simple in construction, and spare and accessory parts are less, because latch hook body uses integral structure, so, it is difficult to break off relations, increases security, and due to the reduction of spare and accessory parts, reduce the cost of manufacturing enterprise.
Description
Technical field
The utility model belongs to lock technology field.
Background technology
The lockable mechanism of existing vehicle turning driver's cabin is typically constituted using latch hook and jam plate, although it is simple in construction but due to
, often there is accident, there may come a time when to cause casualties in the problem of locking has very big always safely.Occur as soon as accordingly
Hydraulic lock, but its is complicated, spare and accessory parts are more, and processing gets up comparatively laborious, are that manufacturing enterprise adds burden in cost.
The content of the invention
The purpose of this utility model is to provide a kind of latch hook body for entirety, and the hydraulic pressure of amount of parts reduction
Lock.
The utility model is made up of upper cover plate and lower cover, and upper cover plate and lower cover are symmetrical members, in upper cover plate with
There is locking bolt neck in the middle of cover plate；Latch hook body is arranged on pin, and pin two ends are separately fixed on upper cover plate and lower cover, and
Rotated by axle of pin, hydraulic jack is installed on lower cover, the stress that the hydraulic push rod of hydraulic jack is withstood on latch hook body
At body, beaer front end coordinates with microswitch；It is that the groove formed at latch hook, latch hook is matched somebody with somebody with latch hook neck in latch hook body leading portion
Close；Hydraulic push rod return spring is cased with pin, hydraulic push rod return spring one end is stuck on hydraulic push rod, and the other end is stuck in
On pin, pin two ends are separately fixed on upper cover plate and lower cover；Latch hook body is placed between upper cover plate and lower cover to answer
Position spring, one end of latch hook body back-moving spring is stuck on rear side of latch hook body, and the other end is stuck on the side wall of lower cover.
The utility model is simple in construction, and spare and accessory parts are less, because latch hook body uses integral structure, so, it is difficult to break off relations,
Increase security, and due to the reduction of spare and accessory parts, reduce the cost of manufacturing enterprise.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is made up of upper cover plate and lower cover 5, and upper cover plate and lower cover 5 are symmetrical members, in upper cover plate and
There is locking bolt neck 2 in the middle of lower cover 5；Latch hook body 10 is arranged on pin 8, and the two ends of pin 8 are separately fixed at upper cover plate with
On cover plate 5, and rotated with pin 8 for axle, hydraulic jack 6 is installed on lower cover 5, the hydraulic push rod 7 of hydraulic jack 6 is withstood on
At beaer 4 on latch hook body 10, the front end of beaer 4 coordinates with microswitch 3；It is latch hook 1, latch hook 1 in the leading portion of latch hook body 10
The groove that place is formed coordinates with latch hook neck 2；Hydraulic push rod return spring 9, hydraulic push rod return spring 9 one are cased with pin 8
End is stuck on hydraulic push rod 7, and the other end is stuck on pin 11, and the two ends of pin 11 are separately fixed on upper cover plate and lower cover 5；
Latch hook body back-moving spring 12 is placed between upper cover plate and lower cover 5, one end of latch hook body back-moving spring 12 is stuck in latch hook body 10
Rear side, the other end is stuck on the side wall of lower cover 5.
During installation, each accessory is arranged on lower cover first, the upper cover plate with lower cover symmetrical member is then buckled, led to
Excess pressure riveting by machine is closed, and above-mentioned accessory is sealed between upper and lower cover plates, by integral installation on vehicle frame, makes locking bolt neck with driving
Sail room locking bolt correspondence.
The course of work：
When driving chamber opening, hydraulic oil is injected to hydraulic jack, hydraulic push rod ejection is promoted, while hydraulic push rod promotes lock
Coupler body is rotated along pin, and beaer 4 departs from the contact with microswitch 3, and microswitch 3 controls alarm ring with prompter
Member notes, and latch hook 1 and locking bolt exact separation, deviates from driver's cabin locking bolt, so that completing driver's cabin departs from lockup state.
During driver's cabin locking, the hydraulic oil of hydraulic jack is released, and hydraulic push rod return spring 9 promotes hydraulic push rod to be retracted into
In hydraulic jack, beaer 4 is set to depart from the thrust of hydraulic push rod, now latch hook body back-moving spring 12 promotes latch hook body to reset, and makes
The hook and slot of latch hook 1 coordinates with locking bolt neck, by driver's cabin locking bolt locking, so as to complete driver's cabin lockup state.
