[0052] In a first aspect, an embodiment of the present application provides a locking mechanism, which is combined with Figure 1 and Figure 2 The locking mechanism comprises a lock housing 1, a lock tongue 2, a driving member 3, a locking elastic member 51 and a locking member 4.

[0053] One end of the driving member 3 is inserted into the lock housing 1 and movably connected with the lock housing 1, the lock tongue 2 is located on one side of the driving member 3 facing the first direction, and the driving member 3 is slidably connected with the lock housing 1 along the first direction.

[0054] The lock tongue 2 is located on one side of the locking elastic member 51 towards the second direction and is in sliding connection with the lock shell 1 along the second direction, wherein the first direction and the second direction are both straight single-head directions, and the first direction intersects with the second direction. In this embodiment, the first direction is perpendicular to the second direction. Specifically, the first direction is a downward direction, and the second direction is a forward direction.

[0055] One end of the locking elastic member 51 is connected with the lock tongue 2, and the other end of the locking elastic member 51 is connected with the lock shell 1. The locking elastic member 51 is used to push the lock tongue 2 to move along the second direction towards the locking member 4, so as to lock the lock tongue 2 with the locking member 4.

[0056] One end of the driving member 3 forms a first guide environment with the lock tongue 2. When the driving member 3 moves along the first direction, the driving member 3 pushes the lock tongue 2 to move along a direction opposite to the second direction through the first guide environment, so as to unlock the lock tongue 2 with the locking member 4.

[0057] It should be noted that the first guide environment can be a guide slope arranged at one end of the driving member 3, or a guide slope arranged on the lock tongue 2, but is not limited thereto.

[0058] In this embodiment, the locking elastic member 51 is a spiral spring, the lock tongue 2 is provided with an avoiding hole 23, and the bottom end of the driving member 3 is provided with a first guide slope 32 towards the rear, so as to form the first guide environment. The avoiding hole 23 can be a blind hole or a through hole. In this embodiment, the avoiding hole 23 is a through hole penetrating through the lock tongue 2 along the first direction.

[0059] During the downward movement of the driving member 3, the bottom end of the driving member 3 is inserted into the avoiding hole 23 and abuts against the lock tongue 2 through the first guide slope 32. When the driving member 3 continuously moves downward, the lock tongue 2 is continuously pushed to move rearward, so that the front end of the lock tongue 2 is separated from the locking member 4. When the bottom end of the driving member 3 is completely inserted into the avoiding hole 23, the lock tongue 2 is unlocked with the locking member 4.

[0060] The locking mechanism provided by the embodiment of the utility model can realize the locking and unlocking of the lock tongue 2 with the locking member 4 quickly and conveniently by moving the driving member 3 along the direction opposite to the first direction to ensure that the driving member 3 is separated from the lock tongue 2, and the locking elastic member 51 automatically pushes the lock tongue 2 to move along the second direction and lock with the locking member 4.

[0061] Further, the end of the lock tongue 2 towards the second direction forms a second guiding environment with the locking member 4. The locking member 4 pushes the lock tongue 2 to move in the direction opposite to the second direction through the second guiding environment.

[0062] It can be understood that the second guiding environment can be a guiding slope arranged at the front end of the lock tongue 2, or a guiding slope arranged at the top end of the locking member 4, but is not limited thereto.

[0063] In the embodiment, the lower part of the front end of the lock tongue 2 is provided with a second guiding slope 21, thereby forming the second guiding environment. During the movement of the locking member 4 to the locking position, the rear part of the top end of the locking member 4 abuts against the second guiding slope 21, and the lock tongue 2 continuously moves backward and compresses the locking elastic member 51 during the upward movement of the locking member 4, until the top of the locking member 4 is separated from the second guiding slope 21, and the lock tongue 2 is completely located at the rear side of the locking member 4. When the locking member 4 is continuously moved upward and reaches the locking position, the lock tongue 2 moves forward a distance under the action of the locking elastic member 51 to realize the locking with the locking member 4.

[0064] The lock tongue 2 realizes the locking with the locking member 4 in the form of a hook or a locking hole 41. When the lock tongue 2 realizes the locking with the locking member 4 in the form of a hook, the top end of the locking member 4 is formed with a protrusion towards the rear. When the lock tongue 2 is locked with the locking member 4, the front end of the lock tongue 2 is located directly below the protrusion, so that the lock tongue 2 can lock the locking member 4, so that the locking member 4 cannot move downward.

[0066] The locking elastic member 51 pushes the lock tongue 2 to insert into the locking hole 41 when the locking member 4 moves into the locking position, so that the lock tongue 2 is locked with the locking member 4 in the third direction. The third direction is perpendicular to the second direction. The driving member 3 pushes the lock tongue 2 to separate from the locking hole 41 when moving in the first direction, so as to release the locking of the lock tongue 2 with the locking member 4 in the third direction.

[0067] It should be noted that the third direction can be a straight single-head direction, a straight double-head direction, or an angular direction, i.e. all directions within a specified angle. In the embodiment, the width of the locking hole 41 is adapted to the width of the front end of the lock tongue 2, and the height of the locking hole 41 is greater than the height of the front end of the lock tongue 2. By limiting the size of the locking hole 41 relative to the front end of the lock tongue 2, the locking member 4 can not only limit the lock tongue 2 in directions other than downward, but also avoid the situation that the lock tongue 2 cannot smoothly separate from the locking member 4 due to too comprehensive limitation of the lock tongue 2.

The part of the handle 61 extending into the inside of the first mounting member 81 can be connected with one or more locking modules at the same time. The locking module comprises but is not limited to the locking shell 1, the locking tongue 2, the driving member 3, the locking elastic member 51, the compression elastic member 52 and the locking member 4 in the utility model, and the number of the locking shell 1, the locking tongue 2, the driving member 3, the locking elastic member 51, the compression elastic member 52 and the locking member 4 in the locking module is one.

[0094] In the embodiment, the two ends of the handle 61 are separated from each other and each end drives a driving member 3 in the locking module.

[0095] In a further optional embodiment of the embodiment, the locking mechanism further comprises a connecting member 7. The connecting member 7 is used to connect two locking members 4. The connecting member 7 is provided with a mounting hole, and the connecting member 7 is fixedly connected with the second mounting member 82 through the mounting hole.

[0096] In the embodiment, the connecting member 7 is fixedly connected with the two locking members 4, and the two locking members 4 connected by one connecting member 7 correspond to one handle 61. By arranging the connecting member 7, the locking member 4 can be accurately installed at the corresponding position of the second mounting member 82, and the stability of the installation of the locking member 4 can be improved.

[0097] The locking and unlocking process of the locking device is as follows:

[0098] When it is needed to separate the first mounting member 81 from the second mounting member 82, in combination with Figure 1 and Figure 7 , only the handles 61 on both sides need to be pulled upward by hand, and the end of the handle 61 connected with the driving member 3 is circumferentially moved relative to the rotating shaft 62 and presses the driving member 3 downward, and the driving member 3 pushes the lock tongue 2 to retreat through the first guide inclined surface 32 during the pressing process. In combination with Figure 8 and Figure 9 , when the lock tongue 2 exits the locking hole 41, the first mounting member 81 is lifted due to the compression of the elastic member 53 during assembly, so that the first mounting member 81 can be directly removed from the second mounting member 82. When the handles 61 on both sides are released, the handles 61 are automatically retracted due to the rebound of the reset elastic member 63, and the driving member 3 also starts to rebound under the action of the compressed elastic member 52 after the handles 61 are released, until it returns to the initial position, that is, the top of the limiting protrusion 31 abuts against the guide cover 14, and the lock tongue 2 rebounds under the action of the locking elastic member 51 and moves to the most front end in the second direction. In this way, the entire lock cylinder mechanism returns to the initial state and waits for the next locking.

[0099] In combination with Figure 10When the first mounting member 81 needs to be assembled with the second mounting member 82, only the first mounting member 81 is put on the second mounting member 82, and then the first mounting member 81 is pressed from top to bottom to push the locking member 4 into the lock shell 1 through the insertion port. During the movement of the locking member 4 from bottom to top relative to the first mounting member 81 to the locking position, the second guide inclined surface 21 is pushed by the locking member 4 from the back side, and the locking elastic member 51 is compressed. When the locking member 4 is pushed into the locking position, the locking tongue 2 is pushed into the locking port 41 on the locking member 4 through the locking elastic member 51, so that the locking tongue 2 is clamped by the locking member 4. At the same time, due to the pressing effect from top to bottom, the pressing elastic member 53 is compressed. When the first mounting member 81 is released, the pressing elastic member 53 pushes the fixed block 15 and the locking tongue 2, so that the first mounting member 81 and the second mounting member 82 are connected firmly and reliably.

[0100] The locking device provided by the embodiment can be disassembled conveniently without the aid of other tools.
