Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-6, an embodiment of the present utility model is provided: a door lock, comprising a lock body 3, wherein a lock tongue 30 and a driving rod 31 for promoting the lock tongue 30 to slide towards the inside of the lock body 3 are arranged on the lock body 3; one surface of the lock body 3 is connected with the first panel 2, and the other surface of the lock body 3 is connected with the second panel 1; the first panel 2 and the first panel 2 are provided with a containing cavity 25 and an actuating member 4; the actuator 4 comprises a handle 40 rotatably mounted in the housing cavity 25; the handle 40 is linked with a sliding block 45 arranged on the other side surface of the accommodating cavity 25, and the sliding block 45 is connected with the driving rod 31 through a linkage piece 46; by rotating the handle 40 in the accommodating cavity 25, the sliding block 45 moves downward, and the linkage piece 46 is driven to rotate, so that the driving rod 31 drives the lock tongue 30 to slide into the lock body 3.

In summary, since the accommodating cavity 25 is provided to enable the handle 40 to work in the accommodating cavity 25, and the handle 40 is located in the accommodating cavity 25 after the external force is removed, the handle 40 can be hidden in the accommodating cavity 25, so that the hidden door handle is adopted, the aesthetic degree of the product is improved, and the problem that the existing door lock handle is easy to hook articles such as clothes, knapsack belts and the like is solved;

In particular, by rotating the handle 40 in the accommodating cavity 25, the sliding block 45 moves downward, and drives the linkage member 46 to rotate, so that the driving rod 31 drives the lock tongue 30 to slide into the lock body 3, thereby realizing normal unlocking of the door lock and simplifying the overall structure of the door lock.

In order to improve the reliability of the power transmission, the sliding block 45 is engaged with a tooth groove provided on the link 46 via a tooth pin 42 provided.

Further, since the handle 40 is connected to the pin seat 24 provided in the accommodating cavity 25 through the pin rod 43 provided therein, and the pin seat 24 is further provided with a reset member 41 for urging the handle 40 to reset, the handle 40 can be driven to reset by the reset member 41, so as to ensure that the handle 40 is always located in the accommodating cavity 25 without external force; wherein the return member 41 is preferably a torsion spring.

Furthermore, since the sliding groove 23 is further provided on the inner side surface of the first panel 2, and the sliding block 45 is slidably matched with the sliding groove 23 through the sliding plate 48 provided thereon, the sliding block 45 can be ensured to directionally slide in the two panels by utilizing the matching of the sliding groove 23 and the sliding plate 48, and meanwhile, the tooth pin 42 on the sliding block 45 can be ensured to be stably and reliably meshed with the tooth slot on the linkage piece 46, so that the reliable transmission of power is ensured. In addition, in order to further raise the reset speed of the handle 40 and the rapid reset of the sliding block 45, a spring is further provided in the chute 23; wherein one end of the spring abuts against the sliding groove, and the other end abuts against the sliding plate 48. Therefore, after the external force is removed, the handle 40 and the sliding block 45 can be automatically and easily reset under the combined action of the reset member 41 and the spring, respectively.

In order to reliably transmit the power of the handle 40 to the sliding block 45, the handle 40 is further provided with a poking block 44, and the poking block 44 passes through the first panel 2 and then is connected with a linkage plate 49 arranged on the sliding block 45, so that when the handle 40 rotates, the poking block 44 hooks the linkage plate 49, and the sliding block 45 can be driven to continuously move downwards along with the continuous downward rotation of the handle 40, so that the lock tongue 30 is driven to retract inwards of the lock body 3.

Further, since the actuator 4 further includes the support plate 47, the support plate 47 is connected to the first panel 2 to define the sliding block 45 and the linkage 46 in the first panel 2, the support plate 47 may be used to connect the first panel 2, define the sliding block 45 between the support plate and the first panel 2, and further avoid the phenomenon that the sliding block 45 is offset left and right during movement, so that the power of the handle 40 is further ensured to be reliably transmitted to the driving rod 31.

On the basis of the above scheme, the first panel 2 and the second panel 1 have the same structure, and the first panel 2 is further provided with a storage cavity 21, so that articles can be stored in the storage cavity 21, for example, a door key is stored therein.

Furthermore, since the first panel 2 is connected with the first cover plate 5, and the second panel 1 is connected with the second cover plate 6, after the key has the storage cavity 21, the two cover plates can be used to seal the key in the storage cavity 21, in addition, when the lock is used indoors, the key is stored in the storage cavity 21, so that the problem that the door cannot be opened due to the loss of the key can be avoided, and meanwhile, the phenomenon that the key is lost in the transportation process of the door lock can be avoided; specifically, the first cover plate 5 and the second cover plate 6 are respectively provided with a buckle, and the buckles are used for being connected with the two panels, so that the stability of the cover plate after being connected with the panels can be enhanced.

Furthermore, since the first panel 2 and the second panel 1 are provided with the notch 20, the two cover plates can be pried open by inserting the flat screwdriver into the notch 20, so that a user can conveniently take the articles in the storage cavity 21.

In addition, since the first panel 2 is further provided with the connecting seat 22, the lock cylinder is convenient to be mounted on the lock body 3, and meanwhile, the connecting seat 22 is also provided with two connecting holes 26 with identical structures, so that when the lock cylinder structure is different, the lock cylinder can be connected with different connecting holes 26, and the lock body 3 can be provided with different types of good lock cylinders; for example, when the lock cylinder is a 50-type lock cylinder, the lock cylinder is connected with the connecting hole 26 below the connecting seat 22 after passing through the lock cylinder by a bolt, and when the lock cylinder is a 58-type lock cylinder, the lock cylinder is connected with the connecting hole 26 above the connecting seat 22 after passing through the lock cylinder by a bolt, so that the device can use at least two types of lock cylinders.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
