Detailed Description

The invention will be further described with reference to specific embodiments.

The first embodiment is as follows: as shown in fig. 1-8, the technical solution of the present invention is preferably applied to an automatic lock, and the so-called automatic lock main body includes other necessary components that complete the basic function of the automatic lock besides the mentioned components, and the non-mentioned components belong to the prior art, and as the functions and the basic structure of the automatic lock are already well-developed products in the market, further brevity and clarity of the expression are not repeated. The following describes the structural design and the working principle of the present technical solution specifically by taking the general structure of the automatic lock as an example.

Firstly, under the locking state, under the action of a lock core shifting fork 8 of the lock core assembly, an unlocking rod part 9 at one end of the lock tongue plate 1 can be triggered, and the unlocking rod part 9 rotates rightwards for a certain angle.

The latched state referred to herein is a state when the main latch tongue 17 is extended, which is a state in which the door is closed. The lock core is a main part for controlling the lock to be unlocked, is a heart of the lock, and is a core part which can rotate and drive the lock bolt to move by matching with the key; in short, it refers to a part into which a key is inserted in the existing lock. The so-called cylinder fork 8 is the part of the cylinder that rotates with the cylinder during rotation. In practice, the lock core may be formed integrally with the lock bolt or may be a separate component which is driven to rotate by the lock core when the lock core rotates.

The strike plate 1 is a plate which is arranged on one side of the lock cylinder and is connected to the main strike 17, and is hinged in the lock housing 12, i.e. it can be pivoted in the lock housing 12. One side of the lock tongue plate 1 close to the lock cylinder can be formed with a touch area used for abutting against the lock cylinder shifting fork 8, the touch area can be a plate, a rod part or a cam, and the touch area can be triggered to rotate only when the lock cylinder shifting fork 8 rotates. Preferably, the technical solution adopts a rod design and is named as an unlocking rod part 9, the unlocking rod part 9 is a rod part which is consistent with the rotation direction of the lock cylinder shifting fork 8, and the unlocking rod part 9 is preferably set to incline towards one side of the lock cylinder shifting fork 8 for reducing the distance required by the lock cylinder shifting fork 8 to touch, so that the lock cylinder shifting fork 8 can contact with the unlocking rod part 9 as early as possible when rotating a smaller angle, thereby triggering the lock tongue plate 1 to rotate.

Preferably, the position of this touch area is located at the lower left side of the rotation axis of the tongue plate 1, so that the lower end of the upper pulling piece 2 can be triggered to swing towards the right side after the touch area is triggered.

As shown in fig. 7 and 8, a clutch lever portion 5 is located at the upper end of the tongue plate 1, a clutch assembly is arranged on the upper layer of the tongue plate 1, an upper shifting piece 2 is arranged in the clutch assembly, and a clutch slot 4 is formed at the upper end of the upper shifting piece 2; in the closed state of the lock, the clutch lever part 5 is clamped in the clutch slot 4. That is to say, the shape and the size between clutch slot 4 and clutch lever 5 should be the adaptation, and the standard of adaptation is that the size requirement of clutch slot 4 can satisfy when unblanking lever portion 9 is rotated by the drive of lock core shift fork 8, can make clutch lever portion 5 unhook from clutch slot 4 smoothly.

The shape of the clutch slot 4 here may be circular, triangular or square, and of course, may also be oval. Certainly, from the perspective of improving product life, the thickness of going up plectrum 2 will increase then the position of separation and reunion draw-in groove 4 will be chamfered or filleted, prevents stress concentration.

When the bolt plate 1 rotates, the clutch rod part 5 rotates leftwards and is separated from the clutch clamping groove 4 of the upper pulling piece 2.

Meanwhile, an upper swing rod 6 is arranged at the front end of the upper shifting piece 2, a swing rod spring 3 is hooked at the upper end of the upper swing rod 6, and the other end of the swing rod spring 3 is connected with a main lock tongue 17; under the conventional state, the rocker spring 3 is in a stretched state, and the clutch rod part 5 is only clamped in the clutch clamping groove 4 under the locking state, so that the upper poking piece 2 cannot rotate all the time. When the clutch rod part 5 is separated from the clutch clamping groove 4, the swing rod spring 3 contracts, and the upper swing rod 6 swings leftwards under the tension of the swing rod spring 3.

The swing rod spring 3 is connected with the main bolt 17, on one hand, the swing rod spring can be directly connected, on the other hand, in a more optimized scheme, the lower end of the main bolt 17 is connected with the unlocking push sheet, and the swing rod spring 3 is connected to one side of the unlocking push sheet. This technical scheme the meaning of the push jack of unblanking can refer to, chinese utility model patent, the patent number is: 201420417958.6, there is a prior art related to unlocking the push plate, and the details are not described herein.

Meanwhile, when it is pointed out here that, the tongue plate 1 and the upper pulling piece 2 both rotate or swing, the pivot point of the swing or the center of the rotation can be designed to be close to the upper side preferentially, and the tongue plate 1 and the upper pulling piece 2 should be arranged concentrically, i.e. should rotate or swing around the same rotating shaft 7.

An unlocking shifting column 15 is formed at the lower end of the upper shifting piece 2, the upper swing rod 6 swings leftwards under the pulling force of the swing rod spring 3, and the unlocking shifting column 15 at the lower end of the rotating fulcrum is inevitably placed to rotate rightwards.

In the embodiment, the middle of the upper pulling piece 2 is provided with a guide groove 10, the tongue locking plate 1 is provided with a clamping pin 11, and when the area below the fulcrum of the upper pulling piece 2 swings to the right, the clamping position of the clamping pin 11 and the guide groove 10 moves from right to left. Thus realizing the function of 'engaging gear'.

The shape of the guide groove 10 is circular and belongs to a shape with a large right and a small left, so that the clamping pin 11 in the guide groove 10 can trigger a touch area to swing from right to left. It should be noted that in actual production, the dimensions of the large and small intersections of the groove widths of the guide grooves 10 should be such that the snap-in pins 11 need to be able to travel from the large side to the small side under the action of external forces. That is, the catching pin 11 should be limited to the side of the guide groove 10 having the larger groove width before the touch region is not activated, and then enter the smaller side by an external force.

The automatic lock body in the lock shell 12 also comprises a component called a right toothed plate 13, the function and the structure of the right toothed plate 13 can refer to Chinese utility model patents, and the patent numbers are: 201220718728.4. which specifically discloses the functional and structural characteristics of the right toothed plate 13. In this embodiment, a pull tab bayonet 14 is formed at the front end of the left side of the right toothed plate 13, the pull tab bayonet 14 is generally arc-shaped, and the specific size is set so that the pull tab bayonet 14 of the right toothed plate 13 can just buckle the unlocking pull post 15 in the bayonet after the unlocking pull tab on the lower side of the upper pull tab 2 moves towards the right side.

At this time, the handle or the door handle is rotated to drive the right toothed plate 13 to rotate, that is, the right toothed plate 13 rotates along with the rotation of the handle in a linkage manner. Meanwhile, the unlocking shifting post 15 is driven to move, the unlocking shifting post 15 moves the upper shifting piece 2 to move, and then the main lock tongue 17 is driven to move integrally. As for the reason and structure that the handle can rotate to drive the right toothed plate 13, the rotation is described in the patent of the prior application, and the description is omitted here.

After the main lock tongue 17 moves to the limited position, the main lock hook 22 at the lower end of the lock tongue plate 1 hooks the transmission shifting post on the first transmission plate, thereby locking the main lock tongue 17 and realizing the whole action of opening the door. The limit position is a position where the main bolt 17 will automatically catch the drive lever during retraction.

When the door continues to be shut down, the oblique spring bolt retracts, trigger the second drive strap and swing towards the left side, the wobbling in-process, the left portion of supporting of second drive strap can support and lean on the lower pivot 7 of right pinion rack 13, the second drive strap continues the swing this moment, because the left portion of supporting of second drive strap has supported and lean on the lower pivot 7 of right pinion rack 13, so the second transmission hook of the lower extreme of second drive strap can be under drive spring's pulling force, the first transmission hook that is pulling first drive strap swings to the right side, even the drive plectrum can also swing to the right side, swing in-process main shackle 22 unhooking, then under main spring's effect, drive main spring bolt 17 stretches out, thereby realize automatic locking.

Therefore, by the combination of the series of actions, the technical scheme has the advantages of simple and convenient unlocking and labor-saving effect, and is particularly suitable for people with insufficient strength, such as children and the old. Utilize this technical scheme structure simultaneously, can also avoid because the key is too much at the lock core internal rotation number of turns, lead to the user to learn the number of turns of rotation at all, whole journey all needs to drive the retraction of main spring bolt 17 with the rotation of key moreover, causes the key card to break in the lock core easily, and this application does not have the problem in this respect at all.

In addition, before the lock core is not rotated, because the lower extreme of going up plectrum 2 is towards left side inclined setting, that can let right toothed plate 13 in the design of size can not catch the post 15 of unblanking in the swing in-process, even rotate the handle like this and also can not lead to the door to be opened, just so can be safer. This corresponds to the "neutral" state in current manual vehicles.

In addition, as a preferred technical scheme, a bearing 30 is sleeved on the outer side of the upper end of the unlocking shifting post 15, and the bearing 30 has the function that when the right toothed plate 13 rotates towards the left side, as long as the shifting sheet bayonet 14 of the right toothed plate 13 does not clamp the unlocking shifting post 15, the right toothed plate 13 can be easily rotated through the rotation of the outer ring of the bearing 30, so that the situation that the right toothed plate 13 directly hits the unlocking shifting post 15 is avoided. That is, in the locked state, even if the handle is rotated back and forth a plurality of times, the unlocking cylinder 15 is not affected.

Preferably, a damping rod 16 is further disposed in the lock case 12 to reduce the extension speed of the main bolt 17 and reduce the impact force during automatic locking. Thereby enabling to increase the sense of high quality of use of the product.

Example two: the embodiment is basically consistent with the embodiment, and the difference is that the shape design of the touch area is a plate which is horizontal to the advancing direction of the unlocking fork, but the plate can exceed the protrusion on one side of the unlocking fork in shape design, so that the rotating angle of the unlocking fork can be reduced, and in practical use, the clutch assembly can be triggered by rotating a very small angle, and then the operation is realized by rotating the handle. The labor saving and the convenience are better for the old and the children.

Or the unlocking rod part 9 can also be vertically arranged, and the design has the advantage that the direction of the unlocking rod part 9 is vertical to the advancing direction of the lock cylinder shifting fork 8, so that the possibility of contact with the lock cylinder shifting fork 8 can be increased to the greatest extent, and the operation stability of a product is improved.

Example three: the present embodiment is basically the same as the first embodiment, and the difference is that a motor 27 is further provided in the lock case 12, a gear 28 is provided on one side of the output end of the motor 27, and a toothed portion 29 adapted to the gear 28 is formed on one side of the unlocking rod portion 9. In the technical scheme, the lock cylinder is driven to rotate by a key, and then the unlocking rod part is triggered to swing in a mode of rotating the lock cylinder shifting fork.

At that time, in order to increase the intelligent degree of the product, the driving unlocking rod part swings in a perfect mode, and the specific expression is that the gear is driven by the motor to rotate, and then the gear is matched with the tooth-shaped part on the tongue plate, so that the unlocking rod part is triggered to swing. Therefore, the unlocking can be realized by controlling the rotation of the motor, and even the lock is driven without a key and a lock cylinder, so that the lock is more comfortable.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
