[0026] The utility model provides a docking assembly.

[0027] See also Figures 1 to 4 The docking assembly includes a first docking device 100 and a second docking device 200 that are docked up and down. The bottom surface of the first docking device 100 is convexly provided with a foot pad 11, and the bottom surface of the foot pad 11 is set as an inclined guide surface, and a card slot 12 is concavely provided on the guide surface. The top surface of the second docking device 200 is provided with a pressure plate 21, and the pressure plate 21 is provided with a docking hole 211 for inserting the foot pad 11. Among them, the second docking device 200 is provided with a locking mechanism, and the locking mechanism includes a self-locking module, and the self-locking module includes a slide plate 22 and a first elastic member 23. The slide plate 22 is slidably arranged below the pressure plate 21, and a locking tongue 221 is arranged on the slide plate 22. One end of the first elastic member 23 is fixedly connected to the slide plate 22, and the other end is fixedly connected to the pressure plate 21. When the first docking device 100 is placed on the pressure plate 21 of the second docking device 200, the foot pad 11 passes through the docking hole 211 and abuts against the locking tongue 211. The slide plate 22 moves forward under the push of the guide surface, and the first elastic member 23 is deformed. When the slot 12 drops to be opposite to the locking tongue 221, the locking tongue 221 is inserted into the slot 12 under the action of the first elastic member 23, and the first docking device 100 is locked and fixed. When the slide plate 22 slides to the unlocking position under the action of external force, the locking tongue 221 is pulled out of the slot 12, and the first docking device 100 is unlocked.

[0028] In the present invention, the first docking device 100 can be a medical host, and the second docking device 200 can be a trolley. The medical host is mounted on the table of the trolley, so that the medical host can be easily moved. At present, the medical host and the trolley are usually fixed with screws. This fixing method requires screwing the screws for both installation and removal, and the operation process is time-consuming and cumbersome.

[0029] Different from the traditional installation method, the technical solution of the utility model has foot pads 11 protruding from the four corners of the bottom surface of the first docking device 100, and then the bottom surface of the foot pad 11 is set as a guide surface, and a card slot 12 is recessed above the guide surface. In addition, the top surface of the second docking device 200 is provided with a pressure plate 21 for supporting the first docking device 100, and the pressure plate 21 is provided with a docking hole 211 for inserting the foot pad 11. At the same time, a locking mechanism is provided on the second docking device 200, and the locking mechanism includes a self-locking module for locking the first docking device 100 and an unlocking module for releasing the first docking device 100. Specifically, the self-locking module includes a slide plate 22 and a first elastic member 23, wherein the slide plate 22 can be slidably mounted below the pressure plate 21, and a first avoidance hole 220 corresponding to the docking hole 211 can be provided on the slide plate 22, and the first avoidance hole 220 can be formed by punching in the plate surface of the pressure plate 21 (the first avoidance hole 220 has four edges), or by opening a notch on the edge of the pressure plate 21 (the first avoidance hole 220 has two edges), in which case the edge of the first avoidance hole 220 can be directly used as a lock tongue 221. Alternatively, a bent piece can be convexly provided on the plate surface of the slide plate 22 to form a lock tongue 221, in which case the first avoidance hole 220 does not need to be provided. The first elastic member 23 can be a spring or a rubber pad, etc., one end of the first elastic member 23 is fixedly connected to the slide plate 22, and the other end of the first elastic member 23 is fixedly connected to the pressure plate 21, and the length direction of the first elastic member 23 is consistent with the sliding direction of the slide plate 22.

[0030] In the present technical solution, when the first docking device 100 needs to be installed on the second docking device 200, first align the foot pad 11 of the first docking device 100 with the docking hole 211 on the pressure plate 21, and then place the first docking device 100 on the pressure plate 21. During this process, the guide surface of the foot pad 11 will contact and abut the locking tongue 211, thereby pushing the slide plate 22 forward, and the first elastic member 23 will deform to generate elastic potential energy. When the slot 12 on the foot pad 11 drops to align with the locking tongue 221, the slide plate 22 will move backward a small step under the action of the recovery shape of the first elastic member 23, so that the locking tongue 221 is stuck in the slot 12, thereby clamping the foot pad 11, thereby locking the first docking device 100. When the first docking device 100 needs to be removed from the second docking device 200, it is only necessary to apply force to the slide plate 22 to slide it to the unlocked position, so that the locking tongue 221 can be pulled out of the card slot 12. At this time, the foot pad 11 is in the unlocked state, and the first docking device 100 can be directly moved away.

[0031] Obviously, through this technical solution, the first docking device 100 and the second docking device 200 do not need to tighten the screws during the locking and unlocking process, which makes the operation convenient and quick, and greatly saves the operation time.

[0032] Reference Figure 2 In one embodiment of the present invention, the unlocking module of the locking mechanism includes a telescopic member 24 and a locking member 25. Corresponding telescopic holes (not shown) are provided on the pressure plate 21 and the slide plate 22. The telescopic member 24 is telescopically inserted into the telescopic hole, and the locking member 25 is provided on the side of the slide plate 22 away from the pressure plate 21. The telescopic member 24 moves downward and protrudes from the slide plate 22 under the pressure of the first docking device 100, so as to be clamped and fixed with the locking member 25, thereby locking the slide plate 22.

[0033] In the initial state, that is, when the first docking device 100 has not yet been placed on the second docking device 200, the telescopic member 24 protrudes upward from the pressure plate 21. When the first docking device 100 is placed on the pressure plate 21 of the second docking device 200, the telescopic member 24 is pressed so as to move downward and protrude the slide plate 22. When the first docking device 100 is in the locked state, the telescopic member 24 and the locking member 25 are separated from each other, and the slide plate 22 can slide freely. When the slide plate 22 slides to the unlocked position under the action of external force, the locking member 25 moves to engage with the telescopic member 24. At this time, the slide plate 22 cannot move and remains in the unlocked position, which is convenient for moving the first docking device 100 away.

[0034] Reference Figure 3 The unlocking module also includes a second elastic member 26, such as a spring, which is sleeved on the circumferential side of the telescopic member 24, and one end of the second elastic member 26 is connected to the telescopic member 24, and the other end of the second elastic member 26 is connected to the pressure plate 21. The telescopic member 24 is telescopically connected to the pressure plate 21 through the second elastic member 26.

[0035] When the telescopic member 24 is compressed, the second elastic member 26 is in a compressed state. After the first docking device 100 is moved away, the telescopic member 24 is reset under the elastic force of the second elastic member 26 to disengage from the locking member 25, thereby unlocking the telescopic member 24 and the locking member 25.

[0036] Continue to refer to Figure 3 A receiving groove 222 is formed in the middle of the slide plate 22 , the locking member 25 is arranged in the receiving groove 222 , and a second avoidance hole 223 is opened on the side wall of the receiving groove 222 .

[0037] In the embodiment shown in the figure, the locking member 25 includes a first straight arm 251 and a second straight arm 252 that are bent, and the angle between the first straight arm 251 and the second straight arm 252 is an obtuse angle. The connection between the first straight arm 251 and the second straight arm 252 is rotatably connected to the slide plate 22 via a rotating shaft 253. A bayonet 2511 is provided on the first straight arm 251, and the bayonet 2511 is used to be clamped and fixed with the telescopic member 24.

[0038] When the first docking device 100 is in a locked state, the free end of the second straight arm 252 is inserted into the second avoidance hole 223, and the first straight arm 251 and the telescopic member 24 are separated from each other. In the process of the slide plate 22 sliding to the unlocked position, the first straight arm 251 gradually approaches the telescopic member 24 and drives the second straight arm 252 to rotate under the rotation of the telescopic member 24. When the slide plate 22 slides to the unlocked position, the second straight arm 252 rotates to abut against the side wall of the accommodating groove 222, so that the telescopic member 24 is inserted into the bayonet 2511 on the first straight arm 251, and the telescopic member 24 and the locking member 25 are clamped and fixed to each other, thereby fixing the slide plate 22 in the unlocked position.

[0039] Further, the unlocking module also includes a third elastic member 27, one end of the third elastic member 27 is connected to the slide plate 22, and the other end is connected to the second straight arm 252. Specifically, the slide plate 22 includes a first panel 224, a second panel 225, a third panel 226, a fourth panel 227 and a fifth panel 228, the second panel 225 is relatively arranged at the length edge of the first panel 224 and is arranged perpendicularly to the first panel 224, the third panel 226 is arranged at an end of the second panel 225 away from the first panel 224 and is arranged perpendicularly to the second panel 225, the fourth panel 227 is arranged at an end of the third panel 226 away from the second panel 225 and is arranged opposite to the second panel 225, and the fifth panel 228 is arranged at an end of the fourth panel 227 away from the third panel 226 and is arranged perpendicularly to the fourth panel 227. The two second panels 225 and the first panel 224 are enclosed to form a receiving groove 222, the second avoidance hole 223 is at least partially opened on the second panel 225, the third elastic member 27 is arranged between the second panel 225 and the fourth panel 227, one end of the third elastic member 27 is connected to the fourth panel 227, and the other end is connected to the second straight arm 252. When the telescopic member 24 is pulled out of the bayonet 2511, the locking member 25 is reset under the action of the third elastic member 27.

[0040] Regarding the installation of the first elastic member 23, a third avoidance hole 229 is opened on the fifth panel 228. The third avoidance hole 229 is a strip hole, and the length direction of the third avoidance hole 229 is the sliding direction of the skateboard 22. A fixing column 212 is protruded from the side of the pressure plate 21 facing the skateboard 22. The fixing column 212 is inserted into the third avoidance hole 229. One end of the first elastic member 23 is fixedly connected to the fifth panel 228, and the other end of the first elastic member 23 is fixedly connected to the fixing column 212.

[0041] In one embodiment of the utility model, a handle 28 is provided at one end of the slide plate 22 facing the sliding direction, and the slide plate 22 can be pulled to the unlocked position by pulling the handle 28. It should be noted that the second docking device 200 is usually provided with a drawer, and the handle 28 is provided inside the drawer to hide the handle 28, thereby ensuring the aesthetic appearance of the drawer.

[0042] In summary, the working process of this docking component is as follows:

[0043] During assembly, the foot pad 11 of the first docking device 100 is aligned with the docking hole 211 on the pressure plate 21, and then the first docking device 100 is placed on the pressure plate 21, so that the telescopic member 24 is pressed down and the slide plate 22 is protruded, and the second elastic member 26 is compressed and deformed, and has an elastic restoring force to drive the telescopic member 24 to rise. At the same time, the guide surface of the foot pad 11 will contact and abut with the locking tongue 211, thereby pushing the slide plate 22 forward, and the first elastic member 23 is gradually stretched. When the slot 12 on the foot pad 11 drops to align with the locking tongue 221, the slide plate 22 will move backward a small step under the pulling force of the first elastic member 23, so that the locking tongue 221 is stuck in the slot 12, thereby clamping the foot pad 11, and the first docking device 100 is in a locked state, and the telescopic member 24 and the locking member 25 are separated from each other.

[0044] When unlocking, open the drawer in the second docking device 200, pull the handle 28, and pull the slide plate 22 to the unlocking position. During this process, the locking member 25 gradually approaches the telescopic member 24, and the first straight arm 251 in the locking member 25 contacts and abuts the telescopic member 24 and drives the second straight arm 252 to rotate under the rotation of the telescopic member 24. The third elastic member 27 gradually stretches until the second straight arm 252 rotates to abut against the side wall of the accommodating groove 222, and the telescopic member 24 is inserted into the bayonet 2511 on the first straight arm 251. At this time, the telescopic member 24 and the locking member 25 are mutually clamped and fixed, and the slide plate 22 is stuck and cannot be further pulled outward and remains in the unlocking position. The first docking device 100 can then be moved away from the pressure plate 21. At the moment the first docking device 100 is moved away, the pressing force of the first docking device 100 on the pressure plate 21 disappears, and the telescopic member 24 rises under the elastic force of the second elastic member 26, thereby being withdrawn from the bayonet 2511, and the locking member 25 is reset under the action of the third elastic member 27, waiting for the next drive.

[0045] In this technical solution, the foot pad 11 is detachably connected to the first docking device 100, such as threaded connection or screw connection. Therefore, when the first docking device 100 is lifted off the second docking device 200, the foot pad 11 can be removed and the first docking device 100 can be placed on another table.

[0046] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
