[0021] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 4 The utility model is further described.

[0022] like Figure 1~2 As shown, the utility model is a sealed door lock structure for a small medical cleaning machine, including a push rod bracket 1 fixedly arranged on the cleaning machine 13, the push rod bracket 1 is fixedly arranged on the cleaning machine 13, the fixed end of the electric linear push rod 2 is fixedly arranged on the push rod bracket 1, the push rod fixing ring 3 is arranged above the telescopic end of the electric linear push rod 2, the telescopic end of the electric linear push rod 2 is arranged through the push rod fixing ring 3, and the push rod fixing ring 3 can ensure that the telescopic end of the electric linear push rod 2 can only be telescoped forward and backward. The telescopic end of the electric linear push rod 2 is connected to the closed section of the elastic fixing clamp 7 through the connecting block 4, and a positioning plate 12 is fixedly arranged above the connecting block 4. The elastic fixing clamp 7 is movably arranged between the limit assemblies. When the electric linear push rod 2 is energized, the telescopic end can drive the connecting block 4, the elastic fixing clamp 7 and the positioning plate 12 to move forward and backward. The utility model is also provided with a first position switch 10 and a second position switch 11. The first position switch 10 is mounted on the push rod bracket 1 and contacts the positioning plate 12 to detect the door opening position of the positioning plate 12; the second position switch 11 is mounted on the cleaning machine 13 and contacts the sealing door 14 of the cleaning machine 13 to provide a door locking signal.

[0023] Specifically, the limit assembly includes a stopper bottom plate 6, a first stopper 5 and a second stopper 9, the stopper bottom plate 6 is fixedly arranged on the cleaning machine 13, the first stopper 5 and the second stopper 9 are symmetrically fixed on the stopper bottom plate 6, and the elastic fixing clip 7 is movably arranged between the first stopper 5 and the second stopper 9. In this embodiment, the distance between the first stopper 5 and the second stopper 9 is equal to the outer diameter of the arc-shaped groove of the elastic fixing clip 7.

[0024] Combination Figure 3~4 The elastic fixing clip 7 is made of elastic material, and an arc-shaped groove adapted to the shape of the locking end of the door lock hook 8 is opened between the closed end and the open end of the elastic fixing clip 7. The locking end of the door lock hook 8 can be inserted into the arc-shaped groove, and the lock tongue end of the door lock hook 8 is connected to the sealing door 14. The open end of the elastic fixing clip 7 is a concave wedge shape, and the minimum opening distance is less than the diameter of the locking end of the door lock hook 8.

[0025] When the utility model is in use, in the door opening state, the second position switch 11 has a signal, and the first position switch 10 has no signal. At this time, the middle arc-shaped groove at the open end of the elastic fixing clip 7 is located in front of the first stop block 5 and the second stop block 9, and the elastic fixing clip 7 can be elastically opened, and the locking end of the door lock hook 8 can be pulled out or pushed into the arc-shaped groove, and the door can be opened and closed normally. Since the closest distance of the concave wedge-shaped opening at the open end of the elastic fixing clip 7 is smaller than the diameter of the door lock hook 8, a certain driving force is required for the door lock hook 8 to enter and exit the arc-shaped groove. The driving force can not only allow the operator to feel whether the door lock hook 8 is pushed into or pulled out of the arc-shaped groove, but also ensure that the door lock hook 8 will not slide freely due to the deadweight of the door when in the arc-shaped groove.

[0026] When the utility model receives a door closing signal, the telescopic end of the electric linear push rod 2 retracts, pulling the connecting block 4, the elastic fixing clip 7, the door lock hook 8 and the positioning plate 12 to move, and the door opening signal disappears until the first position switch 10 receives a door locking signal. At this time, the electric linear push rod 2 stops working, the arc-shaped groove in the middle of the elastic fixing clip 7 is located between the first stop block 5 and the second stop block 9, the opening of the elastic fixing clip 7 is restricted, and the door lock hook 8 is locked inside the arc-shaped groove in the middle of the elastic fixing clip 7, and the door cannot be opened manually.

[0027] When the door opening signal is received, the telescopic end of the electric linear push rod 2 pushes, pushing the connecting block 4, the elastic fixing clip 7, the door lock hook 8 and the positioning plate 12 to move, and the door locking signal disappears until the second position switch 11 receives the door opening signal. At this time, the electric linear push rod 2 stops working, the arc-shaped groove in the middle of the elastic fixing clip 7 is located in front of the first stop block 5 and the second stop block 9, the elastic fixing clip 7 can be elastically opened, and the locking end of the door lock hook 8 can be pulled out or pushed into the arc-shaped groove to open and close the door normally.

[0028] The utility model realizes the self-locking function of the cleaning machine 13 by driving the elastic fixing clip 7 to move between the first stopper 5 and the second stopper 9 through the electric linear push rod 2, greatly improving the safety of the cleaning machine 13 and effectively avoiding dangerous situations such as scalding that may occur during use. At the same time, the utility model realizes the tightening of the sealing door 14 through the telescopic function of the electric linear push rod 2, ensuring that the sealing door 14 is completely sealed, thereby improving the efficiency and level of disinfection and reducing the hospital infection rate.

[0029] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
