[0043] like Figure 1 and Figure 2 As shown, the door body 1 provided in this embodiment can be applied to equipment such as a steamer, an oven, a disinfection cabinet or a dishwasher.

[0044] The door body 1 includes: a door panel 2, a trigger member 3, a linkage assembly and a lock pin 19.

[0045] like Figure 4 and Figure 5 As shown, the trigger member 3 is movably connected to the door panel 2. A sliding connection or a hinge connection can be adopted, and the trigger member 3 can generate relative movement relative to the door panel 2. In this embodiment, the trigger member 3 and the door panel 2 are rotatably connected through a connecting bracket 4.

[0046] The linkage assembly is connected to the trigger member 3 and the lock pin 19 respectively, and is used to transmit the force applied by the user to the trigger member 3 to the lock pin 19, and make the lock pin 19 perform unlocking and locking movements. The linkage assembly can be flexibly adjusted according to the movement type of the trigger member 3 and the relative positions of the trigger member 3 and the lock pin 19 to adapt to different types of products (for example, disinfection cabinets).

[0047] The trigger member 3 can be switched between the first position and the second position, and when the trigger member 3 is in the first position, the lock pin 19 is driven by the linkage assembly to move to the locked state, the lock pin 19 is plugged into the lock hole 21 on the door frame 20, and the door body 1 cannot be opened. When the trigger member 3 is in the second position, the lock pin 19 is driven by the linkage assembly to move to the open state, that is, the lock pin 19 is disengaged from the lock hole 21, the lock pin 19 is no longer restricted by the lock hole 21, and the door body 1 can be freely opened relative to the door frame 20.

[0048] The user manipulates the trigger member 3 on the door panel 2, thereby driving the lock pin 19 to move through the linkage assembly, so that the lock pin 19 is inserted into the lock hole 21 to form a locked state, and the lock pin 19 can also be disengaged from the lock hole 21 to form an unlocked state, and the user can open the door body 1. Unlocking and locking are completely achieved through a mechanical structure, and the service life in a hot and humid environment is longer than that of an electromagnetic switch.

[0049] like Figure 4 and Figure 5 As shown, the door panel 2 is provided with a notch 5 which passes through the front and rear surfaces thereof; when the trigger member 3 is in the first position, the trigger member 3 is located in the notch 5, and the front face of the trigger member 3 is in the same plane as the front face of the door panel 2; when the trigger member 3 is in the second position, the trigger member 3 is at least partially located on the rear side of the notch 5 so that the edge of the notch 5 forms a holding portion 6; the door body 1 also includes a reset structure, and the reset structure is used to reset the trigger member 3 to the first position.

[0050] The shape of the trigger member 3 can be a sheet. In the natural state, the trigger member 3 is flush with the door panel 2. Figure 4 As shown, the two form a complete whole, which is convenient for users to wipe, and there is no protruding handle, so it will not bump into the users passing by. When the door body 1 is in use, the user can push the trigger member 3 inward from the outside of the door body 1, and the trigger member 3 moves inward from the first position to the second position to achieve unlocking, and the edge of the notch 5 on the door panel 2 is exposed, and the edge of the notch 5 forms a gripping portion 6. The user can hold this position with his hand, thereby pushing and pulling the door body 1 to achieve the opening and closing of the door body 1. When the user takes his hand out of the notch 5, the reset structure can make the trigger member 3 return to the first position again, the trigger member 3 blocks the notch 5, and the lock pin 19 automatically returns to the locked state, and the two actions are completed at the same time.

[0051] In this embodiment, the reset structure includes a driving module, for example, the driving module is a push rod motor 13, and the push rod motor 13 automatically drives the trigger member 3 to reset to the first position after receiving the driving signal. In another practicable solution, the reset structure includes a reset spring 17. When the trigger member 3 is in the first position, the reset spring 17 is in a natural state, and when the trigger member 3 is in the second position, the reset spring 17 is compressed and produces elastic deformation. When the user removes the push force on the trigger member 3, the reset spring 17 can drive the trigger member 3 back to the first position.

[0052] In this embodiment, the trigger member 3 is rotatably connected to the door body 1, and when the trigger member 3 flips toward the rear and lower side of the door body 1, the trigger member 3 switches from the first position to the second position. At the same time, the lock pin 19 moves linearly relative to the door panel 2. Specifically, the lock pin 19 moves in the left-right direction. In other feasible solutions, the lock pin 19 can move in the up-down direction.

[0053] like Figure 4As shown, the linkage assembly includes a connecting bracket 4, a connecting rod 14 and a first linear motion structure 15; the connecting bracket 4 includes a rotating seat 7 and a rotating frame 8, the rotating seat 7 is connected to the door panel 2, and the rotating frame 8 is connected to the trigger member 3; one end of the connecting rod 14 is rotatably connected to the rotating frame 8, and the other end is connected to one end of the first linear motion structure 15, and the other end of the first linear motion structure 15 is connected to the locking pin 19; the movement direction of the locking pin 19 is consistent with the movement direction of the first linear motion structure 15.

[0054] like Figure 5 and Figure 6 As shown, a shaft hole 9 is provided on the rotating seat 7, and a first rotating shaft 10 connected to the shaft hole 9 is provided on the rotating frame 8. The rotating seat 7 and the door panel 2 can be connected by adhesive, or by using a threaded member, such as a screw. Similarly, the rotating frame 8 and the trigger member 3 can be connected in the same way. The first rotating shaft 10 extends in the left-right direction. The rotating seat 7 includes two parallel and opposite side panels, each of which is provided with a shaft hole 9. The first rotating shaft 10 is located between the two shaft holes 9, and one end of the first rotating shaft 10 is connected to one of the shaft holes 9, and the other end is connected to the other shaft hole 9. The rotating frame 8 is connected through the two side panels, and the connection stability is better.

[0055] In an implementable solution, the rotating frame 8 flips in the front-to-back direction, and the rotating rotating frame 8 can drive the first linear motion structure 15 to perform linear motion through the connecting rod 14. A limit tube extending in the up-down direction can be provided, and the first linear motion structure 15 is in the shape of a cylinder. The first linear motion structure 15 is located in the limit tube, so that the first linear motion structure 15 can only move in the up-down direction. The locking pin 19 can be directly connected to the first linear motion structure 15, and the locking pin 19 is driven by the first linear motion structure 15 to perform telescopic motion.

[0056] like Figure 7 As shown, a second rotating shaft 12 is provided on the rotating frame 8, and an arc guide groove 11 is provided on the rotating seat 7. The center of the arc guide groove 11 is located on the axis of the shaft hole 9, and the second rotating shaft 12 is slidably connected to the arc guide groove 11.

[0057] like Figure 6 As shown, the second rotating shaft 12 is arranged parallel to the first rotating shaft 10, and an arc guide groove 11 is arranged on each side plate. The second rotating shaft 12 on the rotating frame 8 can slide along the arc guide groove 11, and the arc guide groove 11 guides and limits the rotating frame 8, so that the rotating frame 8 only rotates around the first rotating shaft 10.

[0058] The first linear motion structure 15 may be a movable end in the reset structure, that is, in this embodiment, the reset structure is a push rod motor 13, and the push rod of the push rod motor 13 moves along the first direction to form the first linear motion structure 15. Of course, in other practicable solutions, the first linear motion structure 15 and the reset structure may be two completely independent structural components.

[0059] The linkage assembly further includes a steering structure, which is connected between the first linear motion structure 15 and the locking pin 19 so that the movement direction of the locking pin 19 is different from the movement direction of the first linear motion structure 15 .

[0060] Because the trigger member 3 is turned in the front-to-back direction, the first linear motion structure 15 performs telescopic motion in the up-down direction. Although the lock hole 21 can be provided at the lower edge of the door frame 20, the lock hole 21 is not provided in the left-right direction, which makes the locking more stable. Therefore, in this embodiment, the telescopic direction of the lock pin 19 is twisted to the left-right direction by the steering structure.

[0061] Specifically, the steering structure includes a first rack 22 extending along a first direction, a steering gear and a second rack 25 extending along a second direction, the first rack 22 and the second rack 25 are both meshed with the steering gear; the extension directions of the first rack 22 and the second rack 25 are perpendicular; the first rack 22 is connected to the first linear motion structure 15; the locking pin 19 is connected to the second rack 25.

[0062] In this embodiment, the first direction is the up-down direction, and the second direction is the left-right direction. The first rack 22 is connected to the first linear motion structure 15 through a horizontal bar extending left and right. The first linear motion structure 15 can drive the first rack 22 to move in the up-down direction, and then the first rack 22 pulls the gear to rotate, and the gear drives the second rack 25 to move in the left-right direction. The lock pin 19 connected to the second rack 25 also moves in the left-right direction, thereby realizing the switching between the unlocking and locking states. Furthermore, the number of the lock pins 19 is two, and the two lock pins 19 are symmetrically arranged. In other words, the first linear motion structure 15 can simultaneously drive the two symmetrical lock pins 19 to move toward or relative to each other, so that when the door body 1 is in the locked state, it is more tightly connected to the door frame 20.

[0063] The steering gear includes a first gear 23 and a second gear 24 arranged side by side in the axial direction. In order to avoid interference between the first rack 22 and the second rack 25, the first rack 22 can be arranged to mesh with the first gear 23, and the second rack 25 can be arranged to mesh with the second gear 24. The diameter ratio of the first gear 23 and the second gear 24 can be the same or different.

[0064] like Figure 8As shown, the locking pin 19 includes a connecting portion 27 and a locking tongue 26. The locking tongue 26 is slidably connected to the connecting portion 27, and a floating spring 30 is provided therebetween. The connecting portion 27 is connected to the linkage assembly.

[0065] The lock tongue 26 can be retracted and floated relative to the connection part 27, that is, even if the lock pin 19 is in the locked state, when an external force is applied to the lock tongue 26 in the left and right directions, the lock tongue 26 can compress the floating spring 30 and move toward the side close to the connection part 27, and after the external force is removed, the lock tongue 26 returns to the locked state driven by the floating spring 30. In other words, even if the lock pin 19 is in the locked state, after the user manually closes the door body 1, the inclined top structure of the lock tongue 26 abuts against the door frame 20, which will push the lock tongue 26 close to the connection part 27, so that it passes over the door frame 20 and enters the lock hole 21. After fully entering the lock hole 21, the lock tongue 26 is fully extended to achieve the locking effect.

[0066] The rear end of the lock tongue 26 is provided with two first lock hooks 28 arranged side by side and facing outward, with a gap between the two lock hooks, and the front end of the connecting portion 27 is provided with second lock hooks 29 arranged side by side and facing inward, with the two first lock hooks located between the two second lock hooks. The first lock hook 28 and the second lock hook 29 restrict each other to prevent the lock tongue 26 from being separated from the connecting portion 27.

[0067] A guide rib 31 is disposed on the outer side of the first lock hook 28, and a matching guide groove is disposed on the inner side of the second lock hook 29. The guide rib 31 is slidably connected in the guide groove along the second direction to play a role of limiting and guiding.

[0068] like Figure 3 As shown, the door body 1 further comprises a rear shell 33, which is connected to the door panel 2 and can cover the linkage assembly. The rear shell 33 is provided with a through hole for the end of the lock pin 19 to enter and exit.

[0069] The specific operation of the door body 1 in this embodiment is as follows:

[0070] like Figure 5 As shown, when the first linear motion structure 15 is pushed downward, the trigger member 3 tilts back and opens, and at the same time the first rack 22 moves downward, driving the second rack 25 to move inward through the meshing action of the gears. At this time, the lock tongue 26 is retracted into the rear shell 33, and the door body 1 can be pulled open through the notch 5.

[0071] like Figure 4As shown, when the first linear motion structure 15 moves upward, the trigger member 3 tilts forward and closes, and at the same time the first rack 22 moves upward, driving the second rack 25 to move outward through the meshing action of the gears, and at this time the lock tongue 26 extends out of the rear shell 33; if the door body 1 is in a closed state at this time, the lock tongue 26 extends into the lock hole 21 of the door frame 20, and the door body 1 is locked; if the door body 1 is in an open state at this time, the door body 1 is pushed to close, and when the lock tongue 26 hits the door frame 20, it temporarily contracts under the action of the floating spring 30 until the door body 1 is completely closed, and the lock tongue 26 bounces into the lock hole 21 of the door frame 20.

[0072] The moving stroke of the lock pin 19 is limited and must meet the following requirements: 1. The minimum position of the lock pin 19: when the trigger member 3 is in the maximum open position, the lock tongue 26 of the lock pin 19 just moves to the outside of the lock hole 21 of the door frame 20, so that the door body 1 can be opened smoothly; 2. The maximum position of the lock pin 19: when the trigger member 3 is closed, the lock pin 19 is in the lock hole 21 of the door frame 20, but the end point of the slanted top structure of its lock tongue 26 is outside the lock hole 21 of the door frame 20, so that the slanted top structure can function normally when pushing the door body 1 to close.

[0073] The diameter ratio of the first gear 23 to the second gear 24 should be sufficient to convert the stroke range of the first rack 22 into the above-mentioned stroke range of the locking pin 19 .

[0074] The disinfection cabinet provided by the present invention comprises a door frame 20 and the door body 1; the door frame 20 is provided with a lock hole 21 corresponding to the lock pin 19. Since the disinfection cabinet provided by the present invention uses the door body 1, the disinfection cabinet provided by the present invention also has the advantages of the door body 1.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
