Description

Technical Field

[0001] The utility model relates to the field of machinery, and more specifically to an automatic locking and unlocking structure for use in conjunction with a drip-free quick-release coupling. Background Art

[0002] With the development of modern science and technology and the improvement of the modernization level of production operations in today's society, drip-free quick-release couplings have been widely used in other fluid applications such as liquid transportation and gas transportation. However, since drip-free quick-release couplings generally use various valves or flexible seals to achieve a sealed state under interference fit, a great deal of force needs to be applied to the female and male connectors respectively when replacing or removing the quick-release coupling to counteract the resistance of the seal. When replacing the quick-release coupling in the prior art, multiple people need to cooperate or a single person needs to operate with both hands, which is very inconvenient. Therefore, there is an urgent need to design a structure that can automatically lock and unlock the quick-release coupling to achieve the limitation of the quick-release coupling. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic locking and unlocking structure for use in conjunction with a drip-free quick-release coupling, so that the inserted connector can be automatically limited and a repulsive force against the force for pulling out the other end can be provided, thereby achieving convenient and efficient removal of the connector.

[0004] To achieve the above purpose, an automatic locking and unlocking structure for use in conjunction with a drip-free quick-release coupling is designed, including: a fixed upper plate; a flap connected to the upper plate at the bottom through a rotating shaft, the weight of the flap on one side in front of the rotating shaft is greater than the weight of the flap on the other side behind the rotating shaft, and a convex buckle portion is provided at the bottom of the front end of the flap; an electromagnet provided at the bottom of the upper plate, the position of the electromagnet being matched with one side in front of the flap; a container located below the upper plate and the flap, and a clamping groove matched with the buckle portion of the flap is provided on the upper cover of the container.

[0005] Preferably, the automatic locking and unlocking structure provided by the utility model further includes other technical features, wherein a limiting groove is provided below the container to enable the container to move back and forth in the limiting groove.

[0006] Preferably, the automatic locking and unlocking structure provided by the utility model further includes other technical features, wherein a drip-free quick-release coupling is provided on one side in front of the container.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] Through the cooperation of the upper plate, the flap and the card slot, the automatic locking of the flap is achieved when the container is inserted. Through the electromagnet, the locking and unlocking of the flap are controllable. When automatically locking, a reaction force is provided for the container, so that the staff can remove the quick-change joint by applying a pulling force only on the quick-change joint at one end.

[0012] To make the purpose, principle and structure of the present invention clearer, the following further elaborates with reference to the drawings and specific embodiments.

[0013] The present invention provides an automatic locking and unlocking structure for use in conjunction with a drip-free quick-change joint, including:

[0014] An upper plate 1, the lower side of the upper plate 1 is hinged with a flap 3 through a rotating shaft 2. An electromagnet 7 is also provided on the lower side of the upper plate 1, in front of the rotating shaft 2 and above the flap 3.

[0015] The flap 3 is a plate-like structure, and a buckle 4 is provided at one end of the front side of the flap 3. The weight of the front side section of the connection point of the rotating shaft 2 of the flap 3 is greater than the weight of the rear side section of the connection point, so that the flap 3 always keeps the end of the buckle 4 drooping. The flap 3 is made of a material that can be attracted by the magnetic force of the electromagnet 7.

[0016] A container 5 is provided below the upper plate 1 and below the flap 3. The container 5 is arranged on a limit groove slide rail, so that the container can only slide along the fixed direction of the slide rail in the front-rear direction. A card slot 6 is arranged in the upper cover 8 of the container 5, and the card slot 6 is matched with the buckle 4 through clamping connection. When the buckle 4 is matched with the card slot 6, the buckle 4 limits the card slot 6 in the front-rear direction.

[0017] A quick-change female joint 10 is also provided on the front side of the container 5, and the quick-change male joint 9 is detachably and installably matched with the quick-change female joint 10.

[0018] Specifically, the operation is as follows:

[0019] First, the flap 3 hangs down naturally and the electromagnet 7 is turned off.

[0020] Then, the container 5 is pushed into the device from the back to the front along the limiting slide rail, and the upper cover 8 of the container 5 comes into contact with the buckle 4 of the flap 3, and the flap 3 is naturally lifted up under the support of the upper cover 8. Since the front upper cover 8 is a smooth surface, the buckle 4 can slide freely on the front upper cover 8.

[0021] Then, continue to push the container 5 until the buckle 4 falls into the slot 6 and fully fits, at which point the container 5 can no longer be pushed and is limited in both the front and rear directions. At this point, the quick-change male connector 9 can be held with one hand to achieve plugging and unplugging with the quick-change female connector 10 on the container 5. Since the container 5 is limited, the resistance and pulling force generated when plugging and unplugging the quick-change male connector 9 can be obtained from the reverse force generated by the container 5 being limited, and the container 5 is fully fixed, achieving a single-handed plugging and unplugging operation.

[0022] When the container 5 needs to be replaced, the solenoid valve 7 is turned on, and the solenoid valve 7 generates magnetic force to attract the flap 3 to lift up. Under the magnetic attraction of the electromagnet 7, the flap 3 realizes the upward flipping operation with the rotating shaft 2 as the axis. The upward flap 3 makes the buckle 4 leave the slot 6, thereby releasing the limiting effect of the flap 3 on the container 5. At this time, the container 5 can be pushed out along the limiting slide rail to realize the replacement of the container 5.

[0023] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
