A kind of locking releasing device for sorter
Technical field
The present invention relates to logistics, postal sorting equipment field, specifically, a kind of lock for sorter is related specifically to
Tight release device.
Background technology
At present, mail feeding is generally specified bin by slim mail sorting machine using bucket type letter box.Mail falls into from top
In bucket type letter box, after moving to specified bin, bucket type letter cassette bottom portion turnover panel is opened by linkage, discharge mail, mail is certainly
By falling into its bin.The relieving mechanism of this use connecting rod, because mail is entering when bucket type is believed in box to its bottom turnover panel
Certain impact can be caused, causes the opening or turnover panel of turnover panel to be damaged, cause mail to enter correctly into bucket type letter box, and
The box vibrations of bucket type letter can cause the self-locking state of connecting rod relieving mechanism to be opened in motion process, cause anacoluthon, and reliability is relatively low;
Impulsive force is big during connecting rod mechanism movement simultaneously, noise rings, equipment cost is also higher.
The content of the invention
It is an object of the invention to be directed to deficiency of the prior art, there is provided a kind of locking for sorter discharges dress
Put, to solve problems of the prior art.
Technical problem solved by the invention can be realized using following technical scheme:
A kind of locking releasing device for sorter, including turnover box casing and installed in the turnover box casing
The turnover panel of bottom;It is characterized in that:
Some fulcrum posts are provided with the side of the turnover box casing, one end and the turnover box casing of the fulcrum post are fixed
Connection, is provided with lock on the other end of fulcrum post, and connecting shaft hole, the other end end of fulcrum post are offered on the lock
Portion limits axial location after passing through the connecting shaft hole by circlip for shaft, and lock is rotated centered on fulcrum post;
Groove is provided with the lock, the bottom surface of groove is arc surface, the arc surface of the groove and the axle of fulcrum post
With one heart, the turnover panel is connected the heart with the turnover box casing by axle, and turnover panel is rotated centered on axle, one end end of the turnover panel
Portion is provided with the axle with lock arc surface inscribe, and the other end and the turnover panel of axle are connected;The outside at end where the groove of lock
Be provided with the flexible member for pulling lock to reset, one end of the flexible member and lock elastic connection, flexible member it is another
One end is fixed on the side of turnover box casing by connecting shaft.
Further, also including the trigger element for driving lock to be rotated around fulcrum post, the trigger element is electromagnetism
One kind in iron, straight line cylinder and linear electric motors.
Further, the flexible member is the one kind in torsion spring, compression spring and spring leaf.
Compared with prior art, beneficial effects of the present invention are as follows:
By the axle of turnover panel lateral projections and the real-time tangent structure of the arc surface of lock, turnover panel opening direction is made with its is latched
Tangent line with arc surface is vertical in real time, forms mechanical self-latching.Simultaneously when turnover panel is opened lock and the axle of turnover panel lateral projections it
Between only acted on by frictional force, with self-locking reliability, the characteristics of impact small, noise is small.

Specific embodiment
For technological means, creation characteristic, reached purpose and effect for making present invention realization are easy to understand, with reference to
Specific embodiment, is expanded on further the present invention.
Referring to Fig. 1, a kind of locking releasing device for sorter of the present invention, including turnover box casing 1 and
Installed in the turnover panel 2 of the bottom of turnover box casing 1;
Some fulcrum posts 3, one end and the turnover box casing 1 of the fulcrum post 3 are provided with the side of the turnover box casing 1
It is fixedly connected, lock 4 is installed on the other end of fulcrum post 3, connecting shaft hole is offered on the lock 4, fulcrum post 3
Other end end limits axial location after passing through the connecting shaft hole by by circlip for shaft, during lock is with fulcrum post
The heart is rotated;
Groove 5 is provided with the lock 4, the bottom surface of the groove 5 is arc surface, arc surface and the revolution of the groove
With one heart, the turnover panel is connected with the turnover box casing by axle, and turnover panel is rotated centered on axle, the turnover panel in the axle center of pin
One end end is provided with the axle with lock arc surface inscribe, and the other end and the turnover panel 2 of axle 6 are connected;In the groove of the lock 4
Spring 7 is provided with the outside of 5 places end, one end and 4 elastic connections of lock of the spring 7, the other end of spring 7 pass through connecting shaft
It is fixed on the side of turnover box casing 1.
Present invention additionally comprises the electromagnet 8 for driving lock 4 to be rotated around fulcrum post 3.
Referring to Fig. 2 and Fig. 3, lock 4 around fulcrum post 3 rotate when, can ensure that lock 4 acts on arc surfaces and the side of turnover panel 2
The axle 6 of projection is tangent in real time, so that the tangent lines that the direction of motion of turnover panel 2 acts on arc surfaces with lock 4 are mutually perpendicular to, is formed certainly
Lock, self-locking effect reliability.
When opening, need to only start electromagnet 8 and clash into lock 4, lock 4 is rotated to the axle 6 and lock of the lateral projections of turnover panel 2
Button 4 is disengaged, and turnover panel 2 can then complete to open the door with gravity opens voluntarily, because lock 4 acts on arc surface and turnover panel 2 during this
The axle 6 of lateral projections is tangent in real time, therefore only frictional force acts on two contact surfaces, reduces impact and the noise of mechanism.
When turnover panel 2 is closed, turnover panel 2 is lifted up, and the axle 6 of the lateral projections of turnover panel 2 is contacted with 4 bottom surfaces of lock, lifts lock
Button 4, lock 4 is subject to the pull effect of spring 7 simultaneously, until after the axle 6 of the lateral projections of turnover panel 2 is slipped into lock 4, lock 4 is answered
Position, after forming self-locking, completes the reset of turnover panel 2.
The present invention is not limited to one of the above implementation method, electromagnet 8 can be changed into the shapes such as straight line cylinder, linear electric motors
Formula, the present invention is now straight-line electric magnet 8;Spring 7 can be changed to the forms such as torsion spring, compression spring 7, spring leaf;The shape of lock 4
Can not be form in schematic diagram, need to only meet lock 4 and keep tangent with the axle 6 of the lateral projections of turnover panel 2 in the rotation of fulcrum post 3
.
General principle of the invention and principal character and advantages of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited to the above embodiments, simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
