The lifting oil cylinder is arranged and drives the rotating shaft to ascend and descend, then the rotating mechanism connected to the rotating shaft in a sleeving mode drives the whole cabinet door to ascend and descend, the whole set of device is simple in structure and convenient to operate, an existing normal-pressure sterilization cabinet does not need to be greatly improved, the difficulty that goods are conveyed into the cabinet by a forklift can be greatly reduced, and the using effect is good.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of normal pressure sterilization cabinet production, specifically relates to a normal pressure sterilization cabinet lifting hydraulic door device. BACKGROUND

[0002] Nowadays, the edible mushroom planting mostly adopts the mushroom bag breeding mode, and before the inoculation, the mushroom bag needs to be put into the normal pressure sterilization cabinet for sterilization treatment. Because of the existence of the bottom support leg of the normal pressure sterilization cabinet, the cabinet body entrance is ten centimeters higher than the ground, which leads to the need of the inclined plate for the forklift truck to enter when the forklift truck transports goods, but even so, the forklift truck transports goods and appears this and that problem. The present solution is to dig a ten centimeter deep pit on the ground, and the normal pressure sterilization cabinet is put into the pit, so that the bottom surface of the normal pressure sterilization cabinet entrance is flush with the ground. But in this way, when the cabinet door is opened, the cabinet door needs to be lifted first and then rotated to open, so a normal pressure sterilization cabinet door needs to be specially developed for this situation. SUMMARY

[0003] The utility model aims at overcoming the defects and deficiencies of prior art, and provides a normal pressure sterilization cabinet lifting hydraulic door device which is simple in structure, convenient to operate and good in use effect.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows: a normal pressure sterilization cabinet lifting hydraulic door device, which comprises a rotating shaft installed on a cabinet body and a cabinet door sleeved on the rotating shaft through a rotating mechanism, characterized in that: a lifting oil cylinder is installed on the cabinet body below the rotating mechanism, and the oil cylinder rod of the lifting oil cylinder is fixedly connected with the lower end of the rotating shaft for driving the rotating mechanism to slide up and down.

[0005] The rotating mechanism comprises a sleeve, a connecting plate and a ball bearing, the sleeve and the ball bearing are sleeved on the rotating shaft, one end of the connecting plate is connected with the sleeve, and the other end of the connecting plate is connected with the cabinet door.

[0006] The utility model drives the rotating shaft to lift through the lifting oil cylinder, and then drives the lifting of the whole cabinet door through the rotating mechanism sleeved on the rotating shaft, the whole device is simple in structure and convenient to operate, does not need to make too big transformation to the existing normal pressure sterilization cabinet, can greatly reduce the difficulty of forklift truck transporting goods into the cabinet, and is good in use effect. BRIEF DESCRIPTION OF DRAWINGS

[0007] Figure 1 It is the front view of the utility model.

[0008] Figure 2 It is Figure 1 The local enlarged view of A in figure 2.

[0009] Figure 3 It is the structure schematic diagram of the hydraulic drive part of the utility model.

[0010] In the figure: rotating shaft 1, rotating mechanism 2, cabinet door 3, lifting oil cylinder 4, sleeve 5, connecting plate 6, ball bearing 7, rotating shaft support 8. DETAILED DESCRIPTION

[0011] The utility model will be further explained in detail in combination with the description and specific implementation of the accompanying drawings.

[0012] See Figures 1-3 A normal pressure sterilization cabinet lifting hydraulic door device, including rotating shaft 1 installed on the cabinet body and cabinet door 3 sleeved on rotating shaft 1 through rotating mechanism 2, rotating shaft 1 is distributed in the upper middle lower three section positions of the cabinet body, rotating shaft 1 is fixed in rotating shaft support 8, rotating mechanism 2 is located in rotating shaft support 8, and rotating mechanism 2 includes sleeve 5, connecting plate 6 and ball bearing 7, sleeve 5 and ball bearing 7 are sleeved on rotating shaft 1, ball bearing 7 is located below sleeve 5, one end of connecting plate 6 is connected with sleeve 5, the other end of connecting plate 6 is connected with cabinet door 3, lifting oil cylinder 4 is installed below rotating mechanism 2 in the middle end position of the cabinet body, the oil cylinder rod of lifting oil cylinder 4 is fixedly connected with the lower end of rotating shaft 1, for driving rotating mechanism 2 to slide up and down.

[0013] When the normal pressure sterilization cabinet needs to open the door, the oil cylinder rod of lifting oil cylinder 4 extends, and rotating shaft 1 is lifted upwards, the sleeve 5 sleeved on rotating shaft 1 is lifted upwards together, the sleeve 5 drives cabinet door 3 to ascend through connecting plate 6, and rotating shaft 1 cannot ascend unlimitedly under the limiting of rotating shaft support 8, after cabinet door 3 is separated from the pit bottom, cabinet door 3 can be pushed to rotate around rotating shaft 1 and push away, when the normal pressure sterilization cabinet needs to close the door, reverse operation can be carried out.
