Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1, the present embodiment provides a portable pressure sterilizer, which includes a barrel 10 and a cover 20, wherein the barrel 10 is hermetically connected to the cover 20, the cover 20 covers the barrel 10, a handle 21 is disposed on the cover 20, a locking device 30 is disposed on the barrel 10, and the locking device 30 is configured to be pressed on the cover 20. The locking device 30 comprises two ear portions 31, a support 32 and a screw rod 35, the two ear portions 31 are respectively located on two sides of the barrel body 10, the two ear portions 31 are symmetrically arranged, the support 32 comprises two supporting legs 321 and a cross frame 322, the two supporting legs 321 are respectively inserted into the two ear portions 31, the cross frame 322 is provided with a cylinder 33, the screw rod 35 is in threaded connection with the cylinder 33, one end of the screw rod 35 is fixedly connected with a pressing block 36, and the pressing block 36 is used for being pressed on the handle 21, so that the whole cover body 20 is pressed on the barrel body 10. The other end of the screw 35 is provided with a hand wheel 34, the hand wheel 34 is sleeved with the screw 35, specifically, the hand wheel 34 is provided with a square hole, one end of the screw 35, which is connected with the hand wheel 34, is provided with a square rod, and the square rod is inserted into the square hole, so that the hand wheel 34 is held to rotate the screw 35. The axes of the handle 21, the pressing block 36 and the screw 35 are overlapped, so that the whole cover body 10 is uniformly stressed. When the present embodiment is used, the legs 321 of the bracket 32 are first inserted into the ears 31, so that the bracket 32 is fixed on the ears 31, and then the hand wheel 34 is held by hand, the screw 35 is rotated, so that the screw 35 moves downward, the pressing block 36 is tightly attached to the handle 21, and the cover 20 is tightly attached to the tub 10, thereby preventing steam leakage. When it is desired to remove the lid 20, the screw 35 is rotated in the reverse direction, so that the screw 35 moves upward, and the press-fit block 36 moves away from the handle 21, so that the pressure on the lid 20 is removed, and the lid 20 is removed.

In this embodiment, as shown in fig. 2, the ear portion 31 is provided with an insertion hole 311 and a first pin hole 312, the leg 321 is provided with a second pin hole (not shown), and after the leg 321 is inserted into the ear portion 31 through the insertion hole 311, the pin 37 can pass through the first pin hole 312 and the second pin hole, respectively. This embodiment uses pins 37 to secure the bracket 32 to the ear 31 so that the bracket 32 can be quickly coupled to the ear 31.

In this embodiment, as shown in fig. 3, a bucket rim (not shown) is disposed on the bucket body 10, and a sealing ring 40 is disposed on the bucket rim. In addition, a first annular groove 11 is arranged on the barrel edge, a second annular groove 22 is arranged on the cover body 20, and the first annular groove 11 corresponds to the second annular groove 21.
