The operation of the irradiation device described above is explained below:
opening the door 30, and placing the food to be irradiated on the shelf of the cabinet 20;
the door body 30 is closed, and the door lock 60 is used for locking the door body 30, so that the door body 30 and the cabinet body 20 are locked together, and the door body 30 is not easy to open from the cabinet body 20;
the related device is started, the food is irradiated by the cobalt 60 gamma ray, and in the irradiation treatment process, the door body 30 cannot be easily opened because the door body 30 is locked, so that the cobalt 60 gamma ray can be effectively prevented from leaking out to cause damage to a human body;
after the irradiation treatment of the food is completed, the cobalt 60 gamma source in the cabinet body 20 is wrapped again, so that the door body 30 can be safely opened, and the food can be taken out from the storage rack in the cabinet body 20;
specifically, the toggle structure 210 is toggled, the toggle structure 210 further drives the toggle rotating shaft 220 to rotate, and the rotating shaft 220 is toggled to drive the toggle in-place pointer 230 to rotate;
the in-place shifting pointer 230 in rotation drives the driven turntable 330 to rotate through the driven structure 320, and since the driven turntable 330 is provided with the unlocking contact 331 and the in-place unlocking pointer 340 is provided with the unlocking contact 341 matched with the unlocking contact 331, the unlocking contact 331 on the driven turntable 330 is contacted with the unlocking contact 341 on the in-place unlocking pointer 340 in the rotation process of the driven turntable 330;
when the unlocking contact 331 and the unlocking contact 341 touch, the power supply will contact the door lock 60 through the unlocking contact 331 and the unlocking contact 341, and the door lock 60 is powered on and can perform corresponding unlocking action, thereby unlocking the door body 30.
Here, it should be particularly noted that, the unlocking in-place pointer 340 is disposed in the unlocking driven assembly 300, one end of the unlocking in-place pointer 340 is rotatably sleeved on the fixed support shaft 310, and the other end of the unlocking in-place pointer 340 points to the end surface of the transparent dial 100, and by disposing the unlocking in-place pointer 340, the following advantages can be achieved:
1. the unlocking in-place pointer 340 can be adjusted in a rotating mode, the unlocking in-place pointer 340 is adjusted to different positions, and the unlocking contact 341 on the unlocking in-place pointer 340 is located at different positions, so that the unlocking contact 331 on the driven turntable 330 needs to reach a new position to touch the unlocking contact 341, and the effect similar to password resetting can be achieved;
2. the other end of the unlocking in-place pointer 340 points to the end face of the transparent dial 100, and because the transparent dial 100 is transparent, a worker can see the position where the current unlocking in-place pointer 340 is located through the transparent dial 100, and meanwhile, the worker can also see the position where the shifting in-place pointer 230 is located through the transparent dial 100, so that the shifting structure 210 is adjusted, and as long as the shifting in-place pointer 230 and the unlocking in-place pointer 340 are overlapped, the unlocking contact 331 on the driven turntable 330 can be judged to accurately touch the unlocking contact 341 on the unlocking in-place pointer 340, and unlocking is achieved.
It is further explained that the operation of moving the pointer 230 to the right simultaneously has the following two functions: on one hand, the pointer to the right 230 is shifted to drive the driven turntable 330 to rotate through the driven structure 320, so that the unlocking contact 331 on the driven turntable 330 can be in contact with the unlocking contact 341 on the pointer to the right 340; on the other hand, the indicating device has the indicating function, so that a worker can see the position where the in-place shifting pointer 230 is located through the transparent dial 100, and the easy unlocking can be realized as long as the in-place shifting pointer 230 and the in-place unlocking pointer 340 are overlapped. In this embodiment, an unlocking scale code (not shown) is marked on the end surface of the transparent dial 100, and the unlocking scale code is arranged along the edge of the end surface of the transparent dial 100, so that the unlocking in-place pointer 340 and the shifting in-place pointer 230 can be accurately adjusted to the scale lines by marking the unlocking scale code on the end surface of the transparent dial 100, and the unlocking success rate is improved.
The following describes a specific structure of the toggle mechanism 210 of the unlock toggle assembly 200:
as shown in fig. 5, the toggle structure 210 includes: toggle fixing seat 211, toggle wheel 212 and toggle gear 213.
As shown in fig. 5, the dial wheel 212 is rotatably disposed on the dial fixing base 211, the dial fixing base 211 is provided with a limit post 214, the dial wheel 212 is provided with a limit slot 215, and the limit post 214 is received in the limit slot 215.
As shown in fig. 5, the toggle gear 213 is fixed on the toggle rotating shaft 220, and the toggle wheel 212 is provided with a toggle tooth slot 216 engaged with the toggle gear 213.
As shown in FIG. 5, the toggle structure 210 further includes a toggle return spring 217 for urging the toggle spindle 220 to return.
Here, the operation principle of the toggle mechanism 210 will be explained: the knob 218 disposed on the door 30 drives the toggle wheel 212 to rotate, and the toggle wheel 212 further drives the toggle rotating shaft 220 to rotate through the mutually engaged toggle tooth slot 216 and the toggle gear 213, so that the rotating toggle rotating shaft 220 can drive the toggle in-place pointer 230 to rotate.
In the structural design process of the toggle structure 210, the toggle fixing seat 211 is provided with the limit column 214, the toggle wheel 212 is provided with the limit groove 215, and the limit column 214 is accommodated in the limit groove 215, so that the limit column 214 can limit the toggle wheel 212 by utilizing the limit groove 215, the toggle wheel 212 can only rotate within a limited range, and irreversible part damage caused by the fact that the toggle wheel 212 and the toggle in-place pointer 230 are toggled over is prevented.
The following describes a specific structure of the driven structure 320 of the unlocking driven assembly 300:
as shown in fig. 8, the driven structure 320 includes: a dial return spring 321 for urging the driven dial 330 to return, and a driven lever 322. The follower structure 320 also includes a lever return spring 323 for urging the follower lever 322 to return. One end of the driven lever 322 abuts against the free end of the lever return spring 323, and the other end of the driven lever 322 is pressed against the driven turntable 330.
The operation principle of the driven structure 320 will be explained as follows:
under the action of the turntable return spring 321, the turntable return spring 321 continuously provides elastic restoring force to the driven turntable 330, so that the driven turntable 330 is in a reset position when not influenced by external force; similarly, under the action of the shift lever return spring 323, the shift lever return spring 323 continuously provides elastic restoring force to the driven shift lever 322, so that the driven shift lever 322 is in a return position when not influenced by external force;
in the process that the toggle rotating shaft 220 drives the toggle in-place pointer 230 to rotate, the toggle in-place pointer 230 contacts with the driven shifting lever 322, and the toggle in-place pointer 230 applies force to the driven shifting lever 322, so that the driven shifting lever 322 can get rid of the constraint of the shifting lever return spring 323, and then the driven shifting lever 322 can rotate, and the driven shifting lever 322 in rotation is not pressed on the driven turntable 330 any more;
when the driven shift lever 322 is no longer pressed on the driven turntable 330, the turntable return spring 321 will urge the driven turntable 330 to return, and then the driven turntable 330 will rotate, so that the unlocking contact 331 on the driven turntable 330 will contact with the unlocking contact 341 on the unlocking-to-position pointer 340;
when the force is no longer applied to the knob 218 on the door 30, the toggle rotating shaft 220 is reset under the action of the toggle reset spring 217, so that the toggle-in-place pointer 230 also rotates reversely and resets, the driven toggle lever 322 is no longer reset by the action force of the toggle-in-place pointer 230, the driven toggle lever 322 presses the driven turntable 330 again in the resetting process, so that the driven turntable 330 is no longer in the reset state, and thus the unlocking contact 331 is separated from the unlocking contact 341.
As can be seen from the above, the in-place unlocking pointer 340 can be rotationally adjusted, the in-place unlocking pointer 340 is adjusted to different positions, and the unlocking contacts 341 on the in-place unlocking pointer 340 are also located at different positions, so that the unlocking contacts 331 on the driven turntable 330 need to reach new positions to touch the unlocking contacts 341, and an effect similar to password resetting can be achieved. To better adjust the unlock-to-position pointer 340, the switch device 50 further includes a combination reset assembly 400.
As shown in fig. 9, in particular, password reset component 400 includes: reset shaft sleeve 410, reset wheel 420, reset shaft 430, shaft return spring 440, and reset lever 450.
The reset shaft 430 is rotatably and movably disposed on the reset shaft sleeve 410, two ends of the reset shaft 430 are disposed outside the reset shaft sleeve 410, the reset wheel 420 is disposed at one end of the reset shaft 430, and the reset lever 450 is disposed at the other end of the reset shaft 430.
The shaft return spring 440 is received in the reset shaft sleeve 410, and the shaft return spring 440 is used to urge the reset shaft 430 to reset.
The reset lever 450 abuts against or separates from the unlock-to-position pointer 340.
The operation of the password reset module 400 will be described as follows:
the reset rotating wheel 420 is pressed and rotated by hand, the reset rotating wheel 420 further drives the reset rotating shaft 430 to displace and rotate, the reset rotating shaft 430 further drives the reset shifting rod 450 to displace and rotate, the reset shifting rod 450 can reach a proper position to be in contact with the unlocking in-place pointer 340 in the process of displacing the reset shifting rod 450, and the reset shifting rod 450 can drive the unlocking in-place pointer 340 to rotate in the process of rotating the reset shifting rod 450, so that the position of the unlocking in-place pointer 340 is adjusted, and the effect of password resetting is achieved;
after the position of the unlock in-place pointer 340 is adjusted, the reset wheel 420 is not pressed any more, so that the shaft return spring 440 urges the reset shaft 430 to reset under the action of the shaft return spring 440, and the reset shaft 430 after reset also drives the reset lever 450 to reset.
As shown in fig. 9, the reset shaft sleeve 410 further includes a shaft sleeve body 411 and a spring tension adjusting member 412 screwed on the shaft sleeve body 411. Thus, the spring tension adjusting member 412 can be rotatably adjusted to adjust the elastic force of the shaft return spring 440 in the cavity.
