[0047] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0049] Spatial relationship terms such as "under", "below", "below", "under", "above", "above", etc., can be used here to describe the relationship between an element or feature shown in the figure and other elements or features. At the same time, for example, "directly above the locking mechanism" can be used here to describe that an element or feature shown in the figure overlaps in the upper and lower linear directions, which can be partially overlapped or completely overlapped, depending on the actual situation or the content of the figure. It should be understood that in addition to the orientation shown in the figure, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is turned over, the element or feature described as "under other elements" or "under it" or "under it" will be oriented as "on" other elements or features. Therefore, the exemplary terms "under" and "under" can include both upper and lower orientations. In addition, the device can also include other orientations (for example, rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0050] It should be noted that when an element is referred to as being "fixedly connected" to another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0051] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0052] In a first aspect, an embodiment of the present invention provides a locking mechanism, combined with Figure 1 and Figure 2 The locking mechanism includes: 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 to the lock housing 1 . The lock tongue 2 is located on a side of the driving member 3 facing the first direction. The driving member 3 is slidably connected to the lock housing 1 along the first direction.

[0054] The lock tongue 2 is located on the side of the locking elastic member 51 facing the second direction and is slidably connected to the lock housing 1 along the second direction, wherein the first direction and the second direction are both linear single-head directions, and the first direction intersects 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 to the locking tongue 2 , and the other end of the locking elastic member 51 is connected to the lock housing 1 . The locking elastic member 51 is used to push the locking tongue 2 to move toward the locking member 4 along the second direction so that the locking tongue 2 is locked 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 lock tongue 2 is pushed by the first guide environment to move in a direction opposite to the second direction to release the lock between the lock tongue 2 and the locking member 4.

[0057] It should be noted that the first guiding environment may be a guiding inclined surface provided at one end of the driving member 3 , or may be a guiding inclined surface provided on the locking tongue 2 , but is not limited thereto.

[0058] In this embodiment, the locking elastic member 51 is a coil spring, a avoidance hole 23 is provided on the lock tongue 2, and a first guide slope 32 is provided at the rearward portion of the bottom end of the driving member 3, thereby forming a first guide environment. The avoidance hole 23 can be a blind hole or a through hole. In this embodiment, the avoidance hole 23 is a through hole that penetrates 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 avoidance hole 23 and abuts against the lock tongue 2 through the first guide slope 32. At the same time, the continuous downward movement of the driving member 3 will push the lock tongue 2 to move backward continuously, so that the front end of the lock tongue 2 can be separated from the locking member 4, until the bottom end of the driving member 3 is completely inserted into the avoidance hole 23, thereby achieving the unlocking of the lock tongue 2 and the locking member 4.

[0060] The locking mechanism provided by the embodiment of the present invention is provided with a driving member 3 and a locking elastic member 51. When the lock tongue 2 and the locking member 4 need to be locked, it is only necessary to move the driving member 3 in a 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 can automatically push the lock tongue 2 to move in the second direction and lock it with the lock member 4; when the lock tongue 2 and the locking member 4 need to be released from locking, it is only necessary to move the driving member 3 in the first direction so that the driving member 3 pushes the lock tongue 2 in a direction opposite to the second direction through the first guide environment, and the lock tongue 2 and the locking member 4 can be released. In this way, the locking and unlocking of the lock tongue 2 and the locking member 4 can be quickly achieved, and the operation is convenient and quick.

[0061] Furthermore, one end of the locking tongue 2 facing the second direction forms a second guiding environment with the locking element 4. The locking element 4 pushes the locking tongue 2 to move in a direction opposite to the second direction through the second guiding environment.

[0062] It is understandable that the second guiding environment may be a guiding inclined surface provided at the front end of the locking tongue 2 or a guiding inclined surface provided at the top end of the locking member 4, but is not limited thereto.

[0063] In this embodiment, a second guiding slope 21 is provided at the lower part of the front end of the locking tongue 2, thereby forming a second guiding environment. When the locking member 4 moves toward the locking position, the rear part of the top end of the locking member 4 contacts the second guiding slope 21, and the locking tongue 2 continuously moves backward and compresses the locking elastic member 51 while moving upward with the locking member 4, until the top of the locking member 4 is separated from the second guiding slope 21, and the locking tongue 2 is completely located at the rear side of the locking member 4. When the locking member 4 continues to move upward and reaches the locking position, the locking tongue 2 moves forward a distance under the action of the locking elastic member 51 to achieve locking with the locking member 4.

[0064] The lock tongue 2 is locked with the lock member 4 in the form of a lock hook or a lock opening 41. When the lock tongue 2 is locked with the lock member 4 in the form of a lock hook, a protrusion is formed at the top of the lock member 4 facing backwards. When the lock tongue 2 is locked with the lock 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 lock member 4 so that the lock member 4 cannot move downward.

[0065] In this embodiment, the locking member 4 is provided with a locking opening 41. The locking opening 41 may be a groove opening toward the locking tongue 2, or a through hole penetrating the locking member 4. In this embodiment, the locking opening 41 is a through hole penetrating the locking member 4 along the second direction.

[0066] When the locking member 4 moves into the locking position, the locking elastic member 51 pushes the locking tongue 2 to be inserted into the locking opening 41, so that the locking tongue 2 is locked with the locking member 4 in the third direction. The third direction is perpendicular to the second direction. When the driving member 3 moves along the first direction, it pushes the locking tongue 2 to be separated from the locking opening 41, so as to release the locking of the locking tongue 2 with the locking member 4 in the third direction.

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

[0068] It should be noted that the movement of the driving member 3 may be manually controlled, directly controlled by other devices, or indirectly controlled by humans with the aid of other devices.

[0069] Furthermore, the locking mechanism further includes: a compression elastic member 52. One end of the compression elastic member 52 is connected to the driving member 3, and the other end of the compression elastic member 52 is connected to the lock housing 1. The compression elastic member 52 is used to push the driving member 3 to move in a direction opposite to the first direction, so that the driving member 3 is separated from the lock tongue 2.

[0070] In this embodiment, the lock tongue 2, the compression elastic member 52 and the locking elastic member 51 are all located in the lock housing 1. The driving member 3 is a rod-shaped structure extending in the first direction. The compression elastic member 52 is a coil spring. The compression elastic member 52 is sleeved on the peripheral side of the driving member 3. The top of the compression elastic member 52 abuts against the driving member 3, and the bottom of the compression elastic member 52 abuts against the lock housing 1. By setting the compression elastic member 52, the driving member 3 can be automatically pushed back to the initial position, so that the locking elastic member 51 can push the lock tongue 2 to lock with the locking member 4 in the locking position. Among them, the initial position is the position where the driving member 3 moves upward to the farthest position from the lock tongue 2, such as Figure 1 The location of the middle drive member 3.

[0071] Furthermore, the lock housing 1 includes a front housing 11 , a rear housing 12 and a pressing plate 13 .

[0072] An installation cavity 121 is formed in the rear shell 12 . The installation cavity 121 penetrates the front and rear ends of the rear shell 12 along the second direction. The locking tongue 2 and the locking elastic member 51 are both located in the installation cavity 121 .

One end of the locking elastic member 51 abuts against the pressing plate 13 , and the other end of the locking elastic member 51 abuts against the locking tongue 2 .

[0075] In this embodiment, the installation cavity 121 is located at the bottom end of the rear shell 12; there are two locking elastic members 51, and two storage holes 22 are provided at the rear end of the lock tongue 2. The front ends of the two locking elastic members 51 are inserted into the storage holes 22 and connected to the lock tongue 2, and the rear ends of the two locking elastic members 51 are in contact with the pressure plate 13. The front shell 11, the rear shell 12 and the pressure plate 13 can facilitate the installation and removal of the lock tongue 2 and the locking elastic members 51.

[0076] At the same time, the rear shell 12 is further provided with an escape groove 123 in the installation cavity 121 . After the driving member 3 pushes the locking tongue 2 to separate from the locking member 4 , the bottom end of the driving member 3 is inserted into the escape groove 123 .

[0077] Furthermore, the lock housing 1 further comprises: a guide cover 14. The guide cover 14 is detachably connected to the rear housing 12 and forms a sliding cavity 161 with the rear housing 12. The installation cavity 121 is located on a side of the sliding cavity 161 facing the first direction and is in communication with the sliding cavity 161, and one end of the driving member 3 passes through the sliding cavity 161 and is movably connected to the lock tongue 2 located in the installation cavity 121.

[0078] In this embodiment, the guide cover 14 is located at the rear side of the top of the rear shell 12 and above the front shell 11; the compression elastic member 52 is located in the sliding cavity 161. The limiting boss 31 is fixedly provided on the circumference of the part of the driving member 3 located in the sliding cavity 161. The limiting boss 31 is adapted to the sliding cavity 161, and the opening of the driving member 3 passing through the top of the guide cover 14 and the connecting hole 122 on the rear shell 12 connecting the sliding cavity 161 and the installation cavity 121 are smaller than the limiting boss 31, so that the driving member 3 can be prevented from being separated from the lock shell 1. Among them, the top end of the compression elastic member 52 abuts against the limiting boss 31, and the bottom end of the compression elastic member 52 abuts against the rear shell 12.

[0079] Furthermore, the lock housing 1 further comprises a fixing block 15. A guide opening 151 is provided on the fixing block 15. The guide opening 151 penetrates the fixing block 15 along the second direction and is adapted to the lock tongue 2, and the lock tongue 2 is slidably connected to the fixing block 15 through the guide opening 151. By providing the fixing block 15, it is possible to ensure that the lock tongue 2 slides smoothly in the lock housing 1, and at the same time ensure that the lock tongue 2 is accurately locked with the locking member 4 and the stability of the locking is ensured. The fixing block 15 is detachably connected to the rear housing 12 or the front housing 11.

[0080] In this embodiment, the fixing block 15 passes through the installation cavity 121 and is detachably connected to the rear housing 12 by screws. The guide opening 151 is communicated with the installation cavity 121 .

The two ends of the handle 61 are respectively pivotally connected to the chassis through the rotating shaft 62 and pass through the chassis to connect with the top of the corresponding driving member 3.

[0092] When the handle 61 is only subjected to the force of the reset elastic member 63, the portion of the handle 61 located outside the first mounting member 81 is in contact with the outer wall of the first mounting member 81 due to the force of the reset elastic member 63. At this time, the driving member 3 is in the initial position under the action of the compression elastic member 52, and the portion of the handle 61 located inside the first mounting member 81 can be in contact with the top of the driving member 3 or can be separated from the top of the driving member 3. In this embodiment, when the portion of the handle 61 located outside the first mounting member 81 is in contact with the outer wall of the first mounting member 81, the portion of the handle 61 located inside the first mounting member 81 can be in contact with the top of the driving member 3.

[0093] It is understandable that the two ends of the handle 61 extending into the first mounting member 81 can be interconnected or separated from each other. The portion of the handle 61 extending into the first mounting member 81 can be connected to one or more locking modules at the same time. The locking module includes but is not limited to the lock housing 1, the lock tongue 2, the drive member 3, the locking elastic member 51, the compression elastic member 52 and the locking member 4 in the present invention, and the number of the lock housing 1, the lock tongue 2, the drive 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 this embodiment, the two ends of the handle 61 extending into the first mounting member 81 are separated from each other, and each end drives a driving member 3 in a locking module respectively.

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

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

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

[0098] When the first mounting member 81 and the second mounting member 82 need to be separated, Figure 1 and Figure 7 , you only need to pull up the handles 61 on both sides by hand, and the end of the handle 61 connected to the driving member 3 moves in a circle relative to the rotating shaft 62 and presses the driving member 3 downward. During the pressing process of the driving member 3, the first guide slope 32 pushes the lock tongue 2 back. Figure 8 and Fig. 9 When the lock tongue 2 exits the locking opening 41, the first mounting member 81 is lifted up because the pressing elastic member 53 is in a compressed state during assembly, so 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 automatically retract due to the rebound of the reset elastic member 63. After the handles 61 are released, the driving member 3 also begins to rebound under the force of the compressed elastic member 52 until it returns to the initial position, that is, the top of the limiting boss 31 abuts against the guide cover 14. At the same time, the lock tongue 2 rebounds under the action of the locking elastic member 51 and moves to the front end in the second direction. In this way, the entire lock core mechanism returns to the initial state and waits for the next locking.

[0099] Combination Fig.10When the first mounting member 81 and the second mounting member 82 need to be assembled, the first mounting member 81 only needs to be placed above the second mounting member 82, and after being positioned by the locking member 4, the first mounting member 81 is pressed from top to bottom to push the locking member 4 into the lock housing 1 through the plug-in interface. In the process of the locking member 4 moving from bottom to top to the locking position relative to the first mounting member 81, the second guide slope 21 is pushed by the locking member 4 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 opening 41 on the locking member 4 through the locking elastic member 51, so that the locking tongue 2 is stuck by the locking member 4. At the same time, due to the pressing action from top to bottom, the pressing elastic member 53 is compressed. When the pressing of the first mounting member 81 is released, the pressing elastic member 53 presses the fixing block 15 together with the locking tongue 2 to ensure that the first mounting member 81 and the second mounting member 82 are firmly and reliably connected.

[0100] The locking device provided in this embodiment does not require any other tools during disassembly and assembly, and is easy to disassemble and assemble.
