Description
Technical field
The present invention relates to a kind of light, succinct Locking means of door more particularly to a kind of integral type retaining mechanism, belong to
The accommodating containers such as general hatch door, hatchcover laterally open the door fastening system.
Background technique
Complex for retaining mechanisms such as existing all kinds of hatch doors, hatchcovers, previous retaining mechanism needs lock core blocking lock bolt
Realize automatic telescopic, such product internal structure is complicated, and part processing cost is high, and complicated structure is also easy to generate Caton, makes
Lock core movement is not flexible.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provides a kind of integral type retaining mechanism, solves existing
There is in technology the problem of structure is complicated, easy Caton.
Technical scheme is as follows:
Integral type retaining mechanism, including shell, drive shaft, pin shaft, lock tongue, spring and circlip, lock tongue are slidably arranged in shell
It is interior, spring is set between the tail end and shell of lock tongue, and the upper surface of lock tongue extension end is plane, and the lower surface of lock tongue extension end is
Groove is arranged in the upper surface of arc surface, lock tongue；Drive shaft is slidably arranged in groove and through lock tongue and shell, drive shaft
Circlip is arranged in the bottom end for stretching out shell, and the top that drive shaft stretches out shell is set with axle sleeve, and the upper surface of drive shaft, which is equipped with, opens
Lockhole；The housing upper surface is equipped with arc-shaped slot pass, and pin shaft passes through through slot and is slidably arranged in the groove of lock tongue, pin shaft
Top is set with connecting plate, and connecting plate is vertical with the axle sleeve of drive shaft to be connected.
The groove is T connected in star, and the corner between the translot and cannelure of T connected in star is arc surface.
Angle between the circular arc lower surface of the lock tongue and plane upper surface is greater than 45 degree, less than 90 degree.
Gasket is equipped between the axle sleeve and housing upper surface of the drive shaft.
The drive shaft is gap-matched with shell.
The positive effect of the present invention is as follows:
(1) lock tongue arc surface and upper plane included angle of slotting are greater than 45 degree, less than 90 degree, after guaranteeing lock tongue touching lockhole, can pass through
Lock tongue cambered surface makes lock tongue to shell contract, and the groove processed on lock tongue both can guarantee that drive shaft was fixed on completely through lock tongue
On shell, make lock tongue free extension can be made without clamping stagnation in the motionless situation of drive shaft again.
(2) unlock is easy to operate, locks highly-safe.Lock tongue stretching keeps cabin door lock next, makes lock tongue by the pressure of spring
Will not automatic unlocking, operator by L shape key bar be inserted into drive shaft open keyhole in, pressing rotation, overcome the pressure of spring
Power makes in lock tongue income shell, hatch door, that is, openable.
(3) present invention can lock hatch door securely, while facilitate unlocking, and structure is simple, novel form, compared to traditional cabin
The mechanical structure of door locking mode very complicated, greatly reduces cost.Meanwhile drive shaft flexible rotating, rotation could solve
The design of lock keeps hatch door safety higher, easy operation.

Specific embodiment
Embodiment
As shown, integral type retaining mechanism, including shell 1, drive shaft 2, pin shaft 3, lock tongue 4, spring 5 and circlip 7,
Lock tongue 4 is slidably arranged in shell 1, spring 5 is arranged between the tail end and shell of lock tongue 4, the upper surface of lock tongue extension end is flat
Face, the lower surface of lock tongue extension end are arc surface, and the angle between the circular arc lower surface of lock tongue and plane upper surface is greater than 45 degree,
Less than 90 degree.T connected in star 10 is arranged in the upper surface of lock tongue, and the corner between the translot and cannelure of T connected in star is arc surface；It drives
Turn axis 2 is slidably arranged in groove 10 and through lock tongue and shell, and circlip 7 is arranged in the bottom end that drive shaft 2 stretches out shell, drives
The top that turn axis stretches out shell is set with axle sleeve 8, and the upper surface of drive shaft is equipped with open keyhole 12；The housing upper surface is set
There is arc-shaped slot pass 11, pin shaft 3 passes through through slot 11 and is slidably arranged in the groove 10 of lock tongue, and the top of pin shaft is set with connecting plate 9,
Connecting plate is vertical with the axle sleeve of drive shaft to be connected；Gasket 6 is equipped between the axle sleeve and housing upper surface of the drive shaft.
When hatch door is closed, the extension end circular arc face contact lockhole of lock tongue 4 and to 1 contract of shell, holddown spring 5 works as lock
Tongue 4 is taken in completely in shell 1, and hatch door is closed, and lock tongue crosses lockhole edge, under the reaction force of spring 5, makes it restore to lock
Lock tongue is resetted by the elastic force of spring and is locked to realize automatic fastening function by the fully extended state of tongue.
When hatch door is opened, it can be operated by key as shown in Figure 4.The key of open keyhole will can be inserted first
It is inserted into the open keyhole of drive shaft, rotates key, pin shaft 3 slides into through slot end face, by lock tongue to 1 contract of shell, compresses
Spring 5, when lock tongue is taken in shell completely, hatch door is at this time in the open state.Arc-shaped slot on shell has one to rotation
Fixed guiding and position-limiting action can guarantee that lock tongue withdraws completely and prevents lock tongue from takeing in excessively, and spring overloads Problem of Failure, institute
The key stated is the L shape hexagonal prisms bar to match with unlocking hole shape.
In terms of selection, since product is locking mechanism part, and use environment is moist water environment, therefore lock tongue uses
304 stainless steels, spring are 306 stainless steels, and shell uses 304 stainless steels.These are common metal material, increase product
Exploitativeness.
When unlock, the dynamics for comprehensively considering everyone is different, limits, is effectively ensured to drive shaft rotational angle
Unlock the control of angle.Lock tongue can return to original state under the action of the spring.The circular arc of lock tongue is formulated, drive shaft and shell
Body is gap-matched, and lock tongue locking is effectively ensured and fixes.
