Description
Technical field
The present invention relates to a kind of container lock, the lockset of the quick unlatching container of more particularly to a kind of container.
Background technology
Its latch hook promotes the anti-of lock generation when the operation principle of the tapered end lock used on the market at present is tapered end rotation
Active force opens container door（Hereinafter referred to as chamber door）, now produced frictional force is very big, when causing open and close chamber door very
Painstakingly.In tapered end lock as shown in Figure 1, the background technology, in opening process, tapered end deposits bump contact with lock, from
And increase frictional force, and there is the design irrationality of torque, that is, the design of lever is unreasonable, so as to cause to open
Enter laborious situation.
The content of the invention
For above-mentioned technological deficiency, it is intended to which it is all that latch hook promotes lock to open chamber door to change the product used on the market at present
Phenomenon utilize rotary flange there is provided one kind, then contact of the tapered end with lock be apart from short, can be used according to lever principle less
Strength opens the tapered end of chamber door, lock.
To complete foregoing invention purpose, what the present invention was realized in：A kind of tapered end that can easily pin container door, lock
Seat, tapered end is installed on container door leaf rotating shaft connecting rod, and lock is installed on the top and bottom of container body, installation site and lock
The position of head is corresponding；
Described tapered end is made up of locking bar, arc lock hook and rotary flange, and described locking bar is in coniform, described arc
Position is inwardly cambered therebetween for latch hook, and arc lock hook back is outwards cambered；Described rotary flange is connected to arc lock
The afterbody of hook, rotary flange is in triangular shape, and its back side is in arcuation, with arc lock hook back phase one to locking bar is installed on arc lock
Hook and rotary flange junction, junction is provided with rotary flange support frame；Rotary flange support frame is fixed on coniform oblique
On face；
Described lock is made up of fixed base plate, lock, lock core cavity and flange guide block, described lock, lock core cavity and
Flange guide block is horizontally arranged on fixed base plate, and lock is trapezoidal, inserts and hooks for arc lock hook, is contacted with arc lock hook
Surface is inclined-plane；Described flange guide block is two pieces and is arranged at the other end of fixed base plate in interior splayed；Described interior eight word
Shape is engaged with rotary flange；Described lock core cavity is passed through for locking bar.
The rotary flange operation principle of product of the present invention be with the inside of the main lock of lock for basic point rotation, locking bar center line with
The contact point of flange and lock is rotated for basic point and drives chamber door to open, and certain is inclined because lock and flange guide block have
Inclined-plane, therefore as chamber door is opened, distance is increasing between it, reduces frictional force.
Above-mentioned technical proposal is improved further, upper surface and the lower surface of rotary flange gradually become in y direction
Narrow, X direction medial surface becomes narrow gradually to form certain angle to lateral surface.The length of described rotary flange is longer than latch hook
Degree is short.Latch hook upper surface has the inclination of equal angular size with lower surface along y direction；The latch hook outside curve and interior
N-Side surf becomes narrow gradually to form certain angle of inclination.The fixation base plate bottom surface of lock is locally fluted, and the width of groove is more than lock
The height of button.The inner top side face and lower surface of the lock of lock with the latch hook of tapered end be correspondingly formed on the inside of the guide blocks of locks with
The rotary flange profile of tapered end match locks lock inner side be provided with inner prop, column circular arc with tapered end latch hook correspondence.
Its latch hook is not contacted tapered end with lock when rotated, and the bottom surface of lock is locally fluted.
When opening chamber door, tapered end is rotated, and rotary flange thereon is contacted with the front end face of lock, rotary flange with
Do and rotate centered on the inner prop of main lock front end face, accomplish minimum friction forces；According to length of the lever principle due to rotary flange
Degree is shorter than the length of latch hook, i.e., the arm of force is short, therefore can open chamber door with regard to that can push inner prop open with smaller power.The rotation of tapered end is convex
Edge is formed by y direction, therefore (maximum 180 degree) increase and the contact angle of lock during tapered end rotation, can be to greatest extent
Chamber door is opened, separately, X direction also form flange and strengthen intensity.
The latch hook upper surface of tapered end has the inclination of equal angular size with lower surface along y direction；On the outside of rotary flange
Curved surface and inner curve also become narrow gradually to form certain angle of inclination.Projection upper surface gradually becomes with lower surface in y direction
Narrow, X direction medial surface becomes narrow gradually to form certain angle to lateral surface.
For the latch hook and rotary flange of correspondence tapered end, the inner top side face and lower surface of the main lock of lock are with tapered end
Latch hook is correspondingly formed, and is matched on the inside of the guide block of lock with the projection profile of tapered end, therefore latch hook and rotary flange can pass through
Lock groove and guide block are easily extracted.
Latch hook and rotary flange are facilitated insertion into and extracted when being rotated for tapered end, and certain inclination has been done in X direction
Angle, the lock inwall and guide block inner side end of lock are also corresponding formation certain angle.
The main lock of lock and the outer upper end face of guide block and lower surface form certain angle, and punching is disperseed when being impacted
Hit power；Frictional force when being contacted to reduce with rotary flange, the inner prop of main lock is designed to Rouno Cormer Pregrinding Wheel.
