DETAILED DESCRIPTION

[0022] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0023] See also Figure 1-5 The utility model provides an embodiment of a lock that can be locked by reverse lifting, comprising a lock shell 1, a shell cover 4 and a lock tongue 2 whose one end slides in the lock shell 1, and a lock core 3 for prompting the lock tongue 2 to slide is also provided inside the lock shell 1; the lock core 3 comprises a linkage piece 30 linked to the lock tongue 2, one side of the linkage piece 30 is rotatably connected with a first paddle 32, and the first paddle 32 is rotated on the linkage piece 30 to prompt a swinging piece 33 arranged on the linkage piece 30 to swing on the linkage piece 30; a second paddle 38 is further provided on a side of the linkage piece 30 away from the first paddle 32, and the second paddle 38 is also rotatably mounted on the linkage piece 30; one side of the swinging piece 33 conflicts with a first protrusion 5 provided on the inner side of the shell cover 4.

[0024] In summary, when the door inner handle drives the first paddle 32 to rotate counterclockwise on the linkage plate 30, the inner side surface of the first paddle 32 fits with the outer side surface of one end of the swinging member 33, and as the first paddle 32 continues to rotate, one end of the swinging member 33 can be moved toward the inner side of the lock housing 1, and the other end can move away from the inner side of the lock housing 1. At this time, the swinging member 33 is separated from the second paddle 8. When the door outer handle is turned, the second paddle 38 rotates idly, completing the locking action of the lock cylinder 3.

[0025] When the first paddle 32 rotates clockwise, one end of the first paddle 32 conflicts with the tilted end 314 of the swinging member 33. As the first paddle 32 continues to rotate, the outer side surface of the swinging member 33 slides along the first protrusion 5, prompting the swinging member 33 to reset, that is, both side surfaces of the swinging member 33 are parallel to both side surfaces of the linkage plate 30, and the unlocking action of the lock core 3 is completed. At this time, the user can drive the lock tongue 2 to slide into the lock shell 1 by rotating the door handle outside to complete the unlocking of the lock.

[0026] The device utilizes the swinging of the swinging member 33 inside the linkage plate 30 to simply and conveniently complete the reverse-lifting and locking function of the lock core. At the same time, when the first paddle 32 is rotated clockwise, since the first paddle 32 is linked with the linkage plate 30, as the linkage plate 30 continues to rotate, the lock tongue 2 can be driven to slide into the lock shell 1 to complete the unlocking action of the lock. Based on this, the lock has a more sophisticated structure while realizing the reverse-lifting and locking function of the lock core 3, and can also simplify the structure of the lock and the lock core.

[0027] In order to expand the versatility of the lock, that is, the installation direction of the lock can adapt to the opening direction of the door body; the other side of the swinging member 33 conflicts with the second protrusion 6 provided on the inner side of the lock shell 1, and further, the first paddle 32 and the second paddle 38 have the same structure, and the first paddle 32 conflicts with the outer side surface of one end of the swinging member 33 through its inner side surface, so that the swinging member 33 swings in the linkage plate 30.

[0028] In summary, when the lock is unlocked, the lock tongue 2 slides from left to right, and the first paddle 32 is located inside the room, which can complete the reverse lifting and locking function; when the lock is unlocked, the lock tongue 2 slides from right to left, and the second paddle 38 is located inside the room, and the second protrusion 6 is used to cause the swinging member 33 to reset, which can also complete the reverse lifting and locking function. Therefore, the sliding direction of the lock tongue 2 can be adjusted according to the opening direction of the door body to enhance the versatility of the lock, so that the installation direction of the lock is not restricted.

[0029] Specifically, since the first paddle 32 is also provided with a hook 311, and the hook 311 contacts one end of the swinging member 33, the first paddle 32 causes the linkage piece 30 to be linked. Therefore, when the hooks 311 on the two paddles are hooked on the raised end 314 of the swinging member 33, the linkage member 30 can be driven to rotate, and during the rotation process, the first protrusion 5 and the second protrusion 6 can cause the swinging member 33 to reset.

[0030] At the same time, the end of the swing member 33 away from the tilted end 314 is the sliding end 315. When the swing member 33 is reset, the two sides of the tilted end 314 protrude outside the linkage piece 30, so that the hook body 311 can smoothly hook the swing member 33; at the same time, the first paddle 32 and the second paddle 38 are both in contact with the side of the sliding end 315 facing the linkage piece 30, and the height of the protrusion of the side of the sliding end 315 gradually increases from the sliding end 315 to the tilted end 314. Therefore, when the two paddles rotate, they can reliably cause the swing member 33 to swing in the linkage piece 30.

[0031] In order to ensure the stable and reliable swinging of the swing member 33, the swing member 33 is connected to the pivot pin seat 39 provided on the linkage plate 30 through the pivot pin rod 31. Therefore, the swing member 33 can swing with the pivot pin rod 31 as the rotation center axis, thereby promoting the stable and reliable swinging of the swing member 33 so that the raised end 314 can protrude to the outside of the linkage plate 30.

[0032] On the basis of the above scheme, in order to improve the safety of the lock, a locking member 310 is further provided on the linkage plate 30, and the locking member 30 is abutted against the swinging member 33 to achieve locking of the swinging member 33. Therefore, the locking member 310 can be used to press against the swinging member 33 to solve the problem that the swinging member 33 swings automatically after the external force from the handle disappears.

[0033] Specifically, since the locking member 310 includes a top ball 35, and the top ball 35 is adapted to be connected with the ball socket 312 provided on the end surface of the swing member 33 to achieve locking of the swing member 33, the stability of the swing member 33 can be ensured by the cooperation between the ball socket 312 and the top ball 35.

[0034] Furthermore, since the locking member 310 also includes a spring 36 for urging the top ball 35 to press against the ball socket 312, and is adaptively connected to the connecting seat 34 provided on the linkage plate 30 through a bolt 37, so that the spring 36 and the top ball 35 are assembled into the connecting seat 34, the top ball 35 can be further pressed against the ball socket 312 under the joint action of the bolt 37 and the spring 36, thereby ensuring the stable and reliable position of the swing member 33 when in use.

[0035] Furthermore, since there are multiple ball sockets 312, for example, when there are three ball sockets 312, when the tilted end 314 of the swinging member 33 tilts toward the shell cover 2, the top ball 35 is connected to the ball socket 312 near the second paddle 38; when the swinging member 33 is reset, the top ball 35 contacts the ball socket 312 in the middle of the tilted end 314; when the tilted end of the swinging member 33 tilts toward the lock shell 1, the top ball 35 is pressed against the ball socket 312 near the first paddle 32. Therefore, no matter how the installation direction of the lock changes, the locking member 310 can reliably complete the locking task, and after the swinging member 33 is reset, the locking member 310 can also complete the locking of the swinging member 33. In this way, the working position of the swinging member 33 is stable and reliable, so as to further improve the safety of the lock when in use. For example, when the door body opens right inward or right outward, the lock tongue 2 slides from left to right; when the door body opens left inward or left outward, the lock tongue 2 slides from right to left.

[0036] To sum up, by utilizing the cooperation between the ball socket 312 and the top bead 35, and with the support of the spring 36 and the bolt 37, even if the door body vibrates, the swing member 33 will not easily swing, thereby improving the safety of the lock. Even if the door is violently shaken or kicked, the swing member 33 will not swing.

[0037] In addition, since the support parts 313 are provided on both sides of the swing member 33, when the tilted end 314 of the swing member 33 swings to the maximum angle toward the shell cover 2, the support part 313 facing the shell cover 2 abuts against the shell cover 2 to prevent the swing member 33 from continuing to swing. Similarly, the tilted end 314 of the swing member 33 can be prevented from swinging excessively toward the lock shell 1. Based on this, the two support parts 313 are used to limit the swing amplitude of the swing member 33 to prevent the swing member 33 from swinging excessively and causing the lock to fail.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
