[0024] The present utility model will be described in detail below with reference to the drawings.

[0025] Embodiment 1

[0026] A quick connection device for quick positioning and assembly connection between two independent modules, comprising

[0027] A plugging table 1 installed outside the first device housing, a pair of socket tables 2 installed outside the second device housing, a pair of locking and unlocking rods 3 connected between the plugging table 1 and the socket tables 2, and an unlocking block 4 arranged inside the second device housing.

[0028] The following specifically describes the connection and cooperation relationship between each part:

[0029] The plugging table 1 and the two socket tables 2 are both frustum structures. The two sides of the plugging table 1 are configured as plugging surfaces 11, and slots 11a are provided on the plugging surfaces 11. The two socket tables 2 are symmetrically installed and each has a joint surface 21 adapted to be connected with the plugging surface 11 of the plugging table 1, and a clamping groove 21a is provided on the joint surface 21. A socket groove for accommodating the plugging table 1 is formed between the two socket tables 2. When the plugging table 1 is aligned and enters the socket groove between the two socket tables 2, the plugging surfaces 11 on both sides of the plugging table 1 are respectively in contact or clearance fit with the joint surfaces 21 of the two socket tables 2.

[0030] An installation seat 5 is arranged inside the second device housing. The unlocking block 4 is rotatably installed in the middle of the installation seat 5. The two locking and unlocking rods 3 have the same structure and are symmetrically installed in a Y shape on both sides of the installation seat 5, and are respectively horizontally rotatably connected to the two ends of the installation seat 5. The second device housing is provided with two through holes. The two through holes are located on both sides of the installation seat 5 inside the second device housing and inside the two socket tables 2 outside the second device housing. The two locking and unlocking rods 3 respectively pass through the inside and outside of the second device housing via the two through holes. The tail section of the locking and unlocking rod 3 is placed inside the second device housing, and a tension spring 6 is connected between the tails of the two locking and unlocking rods 3. The tension spring 6 makes the tails of the two locking and unlocking rods 3 maintain a contraction force of relatively approaching each other. The head of the locking and unlocking rod 3 extends to the outside of the second device housing and is placed inside the socket table 2. The head of the locking and unlocking rod 3 has a driving claw 31 and a locking claw 32. The length of the driving claw 31 is greater than the length of the locking claw 32, and the locking claw 32 is closer to the side of the plugging table 1. In the unconnected state of the plugging table 1 and the socket table 2, the driving claw 31 at the head of the locking and unlocking rod 3 extends along the clamping groove 21a provided on the joint surface 21 of the socket table 2 and is located in the socket groove between the two socket tables 2, and the locking claw 32 is hidden inside the socket table 2. When the plugging table 1 and the socket table 2 are connected, the locking claw 32 at the head of the locking and unlocking rod 3 extends out of the socket table 2 and is simultaneously inserted into the clamping groove 21a of the socket table 2 and the slot 11a of the plugging table 1, and the driving claw 31 abuts against the outer end surface of the plugging table 1.

[0031] The unlocking block 4 is used to unlock the plugging table 1 and the socket table 2. The unlocking block 4 is rotatably installed in the middle of the mounting base 5, located between the two locking and unlocking rods 3. It can be turned up and down along one side of the mounting base 5. A limiting plate 41 is provided at the bottom of the unlocking block 4. The limiting plate 41 has a locking position in the horizontal position and an unlocking position in the inclined position. When the limiting plate 41 is in the horizontal locking position, that is, placed between the tail sections of the two locking and unlocking rods 3, it can overcome the acting force of the tension spring 6 to keep the heads of the two locking and unlocking rods 3 in the locked state. When the limiting plate 41 rotates upward from the horizontal position to the inclined unlocking position along with the unlocking block 4, that is, the limiting plate 41 disengages from between the two locking and unlocking rods 3. At this time, the tail sections of the two locking and unlocking rods 3 reset and contract under the action of the tension spring 6, so that the locking claws 32 at the heads of the two locking and unlocking rods 3 release the locking of the plugging table 1 and the socket table 2, thereby realizing the separation between the two devices.

[0032] The control of the unlocking block 4 can be realized by an external opening pull rod. One end of the external opening pull rod is outside the housing of the second device and is controlled by a human or an external linkage. The other end of the external opening pull rod extends into the housing of the second device and is connected to the unlocking block 4. It should be understood that the design form of the external opening pull rod can be adaptively selected according to the structure of the second device in the prior art, so this embodiment will not describe this part in detail.

[0033] For the quick connection device of this embodiment, its connection and assembly process is as follows:

[0034] When the first device and the second device are not assembled, they are independent of each other. At this time, inside the housing of the second device, the limiting plate 41 of the unlocking block 4 is in the locked state in the horizontal position, and the two locking and unlocking rods 3 are kept relatively separated under the action of the limiting plate 41, that is, the tension springs 6 at the tails of the two locking and unlocking rods 3 are in the stretched state. Outside the housing of the second device, the driving claws 31 at the heads of the two locking and unlocking rods 3 extend from inside the two socket tables 2 along their card slots 21a to the socket inside the two socket tables 2, and the locking claws 32 at the heads of the two locking and unlocking rods 3 are hidden inside the two socket tables 2.

[0035] Align the plugging table 1 of the first device and push it into the two socket tables 2 of the second device. At this time, the end face of the plugging table 1 will first press and push the driving claws 31 of the locking and unlocking rods 3. During the pushing process, the swinging of the driving claws 31 will simultaneously cause the locking claws 32 on their front sides to extend from inside the socket table 2 along the card slot 21a and insert into the slot 11a of the plugging table 1, that is, the assembly connection of the two devices is completed.

[0036] For the quick connection device of this embodiment, its unlocking and separation process is as follows:

[0037] First, control the unlocking block 4 inside the second device housing through the externally opening pull rod, so that the limiting plate 41 at the bottom of the unlocking block 4 flips upward from between the two locking and unlocking rods 3, thereby releasing the limiting control on the tail sections of the two locking and unlocking rods 3. At this time, the tension springs 6 at the tails of the two locking and unlocking rods 3 contract and reset from the stretched state, driving the tails of the two locking and unlocking rods 3 to move inward, so that the heads of the two locking and unlocking rods 3 expand outward, and further enabling the locking claws 32 to retract from the slots 11a of the plug-in table 1 until they are hidden inside the socket table 2. At this point, there is no connection relationship between the plug-in table 1 and the socket table 2, and the unlocking and separation of the two devices are completed.

[0038] The quick connection device of the present utility model can achieve the quick connection, binding, unlocking and separation between two devices through the coordinated cooperation and action relationship among several structural components. For an assembly production line with requirements for mutual assembly and alignment connection, it has the operational advantages and functional characteristics of saving time and effort, being efficient and convenient. It should be particularly noted that the design of the externally opening pull rod can also be set according to the structural requirements of the device itself. For example, it can be set as an interlocking action associated with the engagement and separation action, which will further expand its applicable scenarios and practicality.
