Specifically, as shown in FIG. 6, both ends of the extension spring 312 are respectively formed with hook-like structures , the two ends of the tension spring 312 are respectively hooked on the sliding connecting rod 311 and the fixed connecting rod 313 . As shown in FIG. 5 and FIG. 6 , the hinge 3 is provided with a push wheel shaft 310, the push wheel shaft 310 is sleeved with a push wheel 306, the push wheel 306 can rotate relative to the push wheel shaft 310, the sliding seat 303 is formed with a second long hole 3031, and the push wheel shaft The two ends of the 310 are respectively connected to the second elongated hole 3031 in a sliding fit. The sliding seat 303 is bent inward to form a baffle plate 309 , and a compression spring 308 for pressing the door body 2 against the cabinet body 5 is provided between the baffle plate 309 and the push wheel 306 . As shown in FIG. 7 , the swing arm 302 is formed with a drive bump 3021 for pushing the push wheel 306 to compress the compression spring 308 . The drive bump 3021 can swing around the swing arm rotating shaft 304 to between the push wheel 306 and the sliding seat rotating shaft 305 . In other words, as shown by the dashed line in FIG. 7 , the contact point of the driving bump 3021 with the push wheel 306 , the center of the push wheel 306 and the center of the slider shaft 305 are all on the same straight line.

The working principle of the door body connection structure of the present invention is briefly described below: the shape of the hinge 3 in FIGS. 3 and 5 corresponds to the closed state of the door body 2. In this state, the door body 2 is in close contact with the edge of the cabinet body 5. 5 , the compression spring 308 is already in a compressed state at this time, so the push wheel 306 exerts a reaction force on the driving bump 3021 , because the push wheel 306 is located on the left side of the driving bump 3021 under the vision in FIG. 5 . , so that the swing arm 302 is subjected to a clockwise moment under the vision of FIG. 5, so that the door body 2 is pressed on the cabinet body 5, so that the sealing performance of the door body 2 is better, and the door body 2 can also be avoided. operation to open. When the door body 2 needs to be opened, the door body 2 is pulled by hand. As shown in FIG. 7, the swing arm 302 swings counterclockwise. The compression spring 308 is further compressed to make the push wheel 306 relatively move to the position shown in FIG. 7 . As described above, in this state, the contact point between the drive bump 3021 and the push wheel 306 , the center of the push wheel 306 and the rotating shaft of the sliding seat The centers of 305 are all on the same straight line, so after releasing the hand, since the thrust direction of the compression spring 308 passes through the center of the sliding seat rotating shaft 305, the thrust of the compression spring 308 is approximately zero to the force arm of the sliding seat rotating shaft 305. In the state shown in FIG. 7 , the thrust of the compression spring 308 generates torque on the swing arm 302 around the swing arm rotating shaft 304 to counteract the torque generated by the tension spring 312 on the swing arm 302 around the swing arm rotating shaft 304 , while the thrust of the compression spring 308 causes the swing arm 308 to generate torque instead. The arm 302 presses on the sliding seat rotating shaft 305 with a relatively large force. In the state of FIG. 7 , since the swing arm rotating shaft 304 drives the sliding seat 303 to move downward, the tension spring 312 has produced an upward pulling force on the sliding seat 303 , this pulling force combined with the downward thrust of the compression spring 308 increases the indirect static friction between the swing arm 302 and the sliding seat 303 and between the swing arm 302 and the hinge housing 301, so in the state of FIG. 7, the swing arm 302 and the hinge housing 301 form a relatively self-locking state, that is, the swing arm 302 and the hinge housing 301 are relatively stationary. The effect of gravity is not enough to destroy the above-mentioned self-locking state, so the door body 2 can hover at a position corresponding to the relative angle between the swing arm 302 and the hinge housing 301 in FIG. 7 . When the human hand continues to open the door body 2, the force of the human hand makes the driving bump 3021 go over the push wheel 306, thus releasing the above-mentioned self-locking state. “M” represents the center of gravity of the door body 2 , “Q” in FIG. 9 represents the swing arm rotating shaft 304 , “T” in FIG. 9 represents the resultant moment resisting the downward swing of the door body 2 , “G” in FIG. 9 represents The gravity of the door body 2, the "X" in Fig. 9 represents the gravity of the door body 2 to the force arm of the swing arm rotating shaft 304. Comparing Fig. 9 and Fig. 10, it can be seen that when the door body 2 is gradually turned down, the force arm X is also corresponding Gradually increase, the moment of the gravity G of the door body 2 to the swing arm rotating shaft 304 gradually increases accordingly, as shown in FIG. 7 and FIG. The sliding seat rotating shaft 305 drives the sliding seat 303 to move, so that the tension spring 312 is gradually elongated. Since the tension force of the tension spring 312 is proportional to the tension length, the torque exerted by the tension spring 312 on the swing arm 302 gradually increases, and The indirect frictional force between the swing arm 302 and the hinge housing 301 and between the swing arm 302 and the sliding seat 303 also gradually increases accordingly. The torque generated by the above frictional force on the swing arm rotating shaft 304 and the tension spring 312 on the swing arm rotating shaft The resultant moment of the moment generated by 304 is approximately the above-mentioned resultant moment T of resisting the downward swing of the door body 2. When the specification of the tension spring 312 is set to match the weight of the door body 2, the door body 2 is in the corresponding position of the swing arm 302. Within the range of the swing angle between the state in FIG. 7 and the state in FIG. 8 , the door body 2 can hover or turn down slowly, so that the use effect of the disinfection cabinet with the door body connection structure of the present invention is better, so as to avoid The door body 2 of the present invention falls down during the opening process, so as to avoid the door body 2 from being bruised and hurting the human body or other objects due to the rapid falling and overturning. When the door body 2 needs to be closed, it is only necessary to lift the door body 2 lightly by hand to make the swing arm 302 swing back to the position shown in FIG. And over the push wheel 306 , when the drive bump 3021 just returns from the self-locking position shown in FIG. 7 , because the thrust of the compression spring 308 increases the force arm of the sliding seat rotating shaft 305 , the compression spring 308 produces an effect on the swing arm 302 . The moment of swinging and restoring is produced, so that the door body 2 is closed and abutted on the cabinet body 5 through the compression spring 308 , and the tension spring 312 also plays a role of assisting the closing of the door body 2 in this process.
