[0041] like Figure 1-Figure 4As shown, the specific embodiment of the utility model provides a locking and unlocking structure of a sterilization transport vehicle, which is used to lock or unlock the sterilization transport vehicle and the sterilization cabinet. The material to be sterilized is placed on the material rack 400. After the two are locked, the material rack 400 is transferred from the sterilization transport vehicle to the sterilization cabinet; after the material rack 400 is transferred to the sterilization cabinet, the two are unlocked and separated. Then the sterilization cabinet starts to sterilize the material to be sterilized on the material rack 400.

[0042] like Figure 3 As shown, in some embodiments, the locking and unlocking structure of the sterilization transport vehicle includes a transport vehicle body 1 and a push rod assembly 4. The transport vehicle body 1 is provided with a transport vehicle track 100 extending along the first direction X, and the first end of the transport vehicle track 100 is used to dock with the sterilization cabinet track 200 in the sterilization cabinet, and the first end of the transport vehicle track 100 is provided with a mounting plate 2; the first end of the push rod assembly 4 is provided with a lock core assembly 5, the lock core assembly 5 includes a first magnetic member 51 and a protrusion 53, and the mounting plate 2 is provided with a second magnetic member 52. The first end of the transport vehicle track 100 docks with the sterilization cabinet track 200 so that the protrusion 53 can be engaged with the docking plate 3 in the sterilization cabinet, and the other end of the push rod assembly 4 can be pushed along the first direction X to make the protrusion 53 disengage from the docking plate 3, and the first magnetic member 51 is attracted to the second magnetic member 52. In this embodiment, a handle 300 is provided at one end of the transport vehicle body 1 to facilitate the operator to move the sterilization transport vehicle.

[0043] When the protrusion 53 is engaged with the docking plate 3, it is in a locked state, and the first magnetic member 51 and the second magnetic member 52 are open; pushing the push rod assembly 4, the push rod assembly 4 can drive the lock core assembly 5 to rotate to make the protrusion 53 disengage from the docking plate 3, which is an unlocked state, and the first magnetic member 51 and the second magnetic member 52 are attracted. After the materials to be sterilized are transferred from the sterilization cart to the sterilization cabinet, the sterilization cart needs to be separated from the sterilization cabinet, and the push rod assembly 4 is pushed to make the protrusion 53 disengage from the docking plate 3, and the first magnetic suction component 51 and the second magnetic suction component 52 are attracted. Even if the sterilization cart is not moved immediately, the protrusion 53 will not move, thereby destroying the unlocked state. At this time, the operator does not need to continue to control the push rod assembly 4, but only needs to pull the handle 300 of the sterilization cart to pull the sterilization cart to the side away from the sterilization cabinet, thereby improving the convenience of unlocking and separating the sterilization cart and the sterilization cabinet. In the process of separating the sterilization cart from the sterilization cabinet, the operator does not need to control the push rod assembly 4 while moving the sterilization cart after unlocking, thereby improving the safety of the operator's operation.

[0044] like Figure 2As shown, in order to ensure the accuracy of the relative position of the mounting plate 2 and the docking plate 3 when they are docked and separated, a guide groove 22 is provided at one end of the mounting plate 2 along the first direction X, and a guide member 32 is provided on the docking plate 3, and the guide member 32 can slide in the guide groove 22 along the first direction X. In this embodiment, two guide grooves 22 are provided at intervals, and the two guide members 32 are respectively provided corresponding to their respective guide grooves 22. The provision of the two guide grooves 22 and the guide member 32 makes the mounting plate 2 and the docking plate 3 more stable when they slide relative to each other.

[0045] like Figure 3 and Figure 4 As shown, the push rod assembly 4 includes a push rod 41, a push rod seat 42 and a push rod spring 43. The push rod 41 is slidably arranged on the transport vehicle body 1 along the first direction X. One end of the push rod 41 is fixedly connected to the push rod seat 42. The push rod seat 42 is connected to the lock core assembly 5. The other end of the push rod 41 extends to one end of the handle 300 of the sterilization transport vehicle along the first direction X, so that the operator can push the push rod 41. The push rod spring 43 connects the transport vehicle body 1 and the push rod 41. The push rod spring 43 is used to reset the push rod 41 along the first direction X. In this embodiment, the push rod seat 42 and the push rod 41 are connected by welding, so that the connection between the push rod 41 and the push rod seat 42 is more stable.

[0046] In order to facilitate the engagement and separation between the protrusion 53 and the docking plate 3 , a slide groove 31 penetrating the docking plate 3 is provided on the docking plate 3 , and the protrusion 53 can slide into or out of the slide groove 31 .

[0047] The lock core assembly 5 includes a lock core plate 55, a connecting member 54 and an elastic member 6. The lock core plate 55 is rotatably connected to the mounting plate 2, one end of the connecting member 54 is slidably connected to the push rod assembly 4, and the other end of the connecting member 54 is fixed to the middle of the lock core plate 55. In this embodiment, a quadrilateral opening is provided on the connecting member 54 at the position where the connecting member 54 is connected to the push rod assembly 4, so that when the push rod assembly 4 slides along the first direction X, the push rod assembly 4 pushes the side wall of the quadrilateral opening to rotate the connecting member 54. The first magnetic member 51 is provided at one end of the lock core plate 55, and the protrusion 53 is provided at the other end of the lock core plate 55; one end of the elastic member 6 is fixed to the mounting plate 2, and the other end is fixed to the position where the connecting member 54 is fixed to the lock core plate 55. In this embodiment, the elastic member 6 is a spring, and an elastic member mounting seat 61 is provided on the mounting plate 2, and a bolt for the spring to hang is provided on the elastic member mounting seat 61, so that the spring is conveniently fixed to the mounting plate 2. The first end of the transport vehicle track 100 is docked with the sterilization cabinet track 200, the docking plate 3 is used to rotate the lock core plate 55, the elastic member 6 is deformed, and the elastic member 6 makes the protrusion 53 clamped in the slide groove 31. The slide groove 31 includes an opening portion opened along the first direction X and a groove portion 311 extending perpendicular to the first direction X. One end of the opening portion passes through the edge of the docking plate 3, and the other end of the opening portion is connected to the groove portion 311. The opening portion is used for the protrusion 53 to slide into the groove portion 311 or to separate the protrusion 53 from the docking plate 3, and the protrusion 53 moves in the opening portion to rotate the lock core plate 55, and the groove portion 311 is used to accommodate the protrusion 53. In this embodiment, after the protrusion 53 is placed in the groove portion 311, the protrusion 53 can protrude from the surface of the groove portion 311 so as to clamp the mounting plate 2 and the docking plate 3.

[0048] Specifically, when the first end of the transport vehicle track 100 is docked with the sterilization cabinet track 200, the protrusion 53 slides into the slide groove 31 through the opening of the docking plate 3, and the protrusion 53 moves in the opening to rotate the lock core plate 55, and the elastic member 6 is stretched. When the protrusion 53 moves to the position of the groove portion 311, the elastic member 6 is reset to place the protrusion 53 in the groove portion 311, thereby realizing the clamping connection between the protrusion 53 and the docking plate 3.

[0049] Specifically, in order to enable the lock core plate 55 to rotate and the elastic member 6 to be stretched when the protrusion 53 moves in the opening, a first inclined surface 7 is provided on the side wall of the opening close to the groove portion 311. The first inclined surface 7 is inclined from the edge of the docking plate 3 toward the side close to the notch of the groove portion 311. When the mounting plate 2 and the docking plate 3 are docked, the protrusion 53 can slide into the slide groove 31 along the first inclined surface 7, and the protrusion 53 causes the lock core plate 55 to rotate when moving along the first inclined surface 7.

[0050] Preferably, a buffer surface 8 is provided between the first inclined surface 7 and a side wall of the groove portion 311 , and the buffer surface 8 extends along the first direction X. The buffer surface 8 provides buffering so that the protrusion 53 can slide more smoothly from the first inclined surface 7 into the groove portion 311 .

[0051] When the sterilization transport cart and the sterilization cabinet are unlocked, the lock core plate 55 rotates, and the first magnetic member 51 and the second magnetic member 52 are attracted to each other, and the lock core plate 55 cannot rotate. If the sterilization transport cart and the sterilization cabinet are directly separated in this state, the protrusion 53 cannot engage with the docking plate 3 next time, so the first magnetic member 51 and the second magnetic member 52 need to be opened before the sterilization transport cart and the sterilization cabinet are completely separated, so as to enable the protrusion 53 to engage with the docking plate 3 next time.

[0052] In order to achieve the purpose of opening the first magnetic component 51 and the second magnetic component 52 before the sterilization transport vehicle is completely separated from the sterilization cabinet, a second inclined surface 9 is provided on the side wall of the opening away from the groove portion 311. The second inclined surface 9 is inclined from the edge of the docking plate 3 toward the side away from the groove portion 311. The push rod assembly 4 can be pushed to make the protrusion 53 disengage from the groove portion 311 and placed in the opening portion. The first magnetic component 51 and the second magnetic component 52 are attracted, and the elastic component 6 is stretched. The transport vehicle body 1 moves away from the docking plate 3 along the first direction X so that the protrusion 53 placed in the opening portion can slide out of the opening along the second inclined surface 9, and the resetting of the second inclined surface 9 and the elastic component 6 causes the lock core plate 55 to rotate, and the first magnetic component 51 and the second magnetic component 52 are separated.

[0053] Preferably, a stopper 21 is provided on the mounting plate 2, and the stopper 21 is used to limit the rotation angle of the lock core plate 55 so that the protrusion 53 can slide into the slide groove 31. When the first magnetic member 51 and the second magnetic member 52 are separated under the action of the elastic member 6 of the second inclined surface 9, and the lock core plate 55 is driven to rotate, the setting of the stopper 21 prevents the rotation range of the lock core plate 55 from being too large, so that the position of the protrusion 53 can support the action of the protrusion 53 sliding into the slide groove 31 next time.

[0054] There are two action processes between the sterilization transport vehicle and the sterilization cabinet:

[0055] During the process of locking the sterilization cart and the sterilization cabinet, the sterilization cart approaches the sterilization cabinet, and the protrusion 53 first contacts the first inclined surface 7. During the process of the protrusion 53 sliding on the first inclined surface 7, the lock core plate 55 rotates, the elastic member 6 is stretched, and the sterilization cart continues to move to the side close to the sterilization cabinet track 200. When the protrusion 53 moves to the position of the groove portion 311, the elastic member 6 restores so that the protrusion 53 is placed in the groove portion 311, completing the locking between the sterilization cart and the sterilization cabinet.

[0056] In the process of unlocking and separating the sterilization transport vehicle from the sterilization cabinet, the push rod 41 is pushed, and the push rod 41 pushes the connecting member 54 to rotate, and the connecting member 54 drives the lock core plate 55 to rotate, so that the protrusion 53 is separated from the groove part 311 and placed in the opening part. At this time, the first magnetic member 51 and the second magnetic member 52 are attracted, and the elastic member 6 is stretched. After the protrusion 53 is separated from the groove part 311, the operator can pull the handle 300 to separate the sterilization transport vehicle from the sterilization cabinet. In the process of the protrusion 53 moving in the direction away from the docking plate 3 through the second inclined surface 9, the reset of the second inclined surface 9 and the elastic member 6 drives the lock core plate 55 to rotate, so that the first magnetic member 51 and the second magnetic member 52 are separated, preparing for the next time the protrusion 53 is engaged with the docking plate 3.

[0057] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
