[0004] The above structure is connected to a sterilizer for sterilizing fungi by using a natural gas burner, but the sterilizer structure does not make any improvements to the top sealing cover structure. The existing sterilizer sealing cover structure is often fixed with a bolt or a snap-on fixation. The operation steps of the above fixing method are not simple and quick enough, and automatic locking cannot be achieved. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a self-locking pressure interlocking device, which solves the problem that the existing locking method is not convenient enough and cannot be self-locking.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a self-locking pressure interlocking device, comprising a sterilizer body, a rotating shaft connecting block, a support beam, and a sealing cover, wherein the rotating shaft connecting block is arranged on the upper end surface of the sterilizer body, the support beam is arranged above the sterilizer body, and the sealing cover is arranged at the lower end of the support beam;

[0007] A movable bolt body is provided at the front end of the support beam;

[0008] The movable bolt body also includes a pin shaft and an air groove. The pin shaft is movably connected to the two side end surfaces of the movable bolt body and adopts the same orientation. The air groove is opened at the side end of the pin shaft and extends inwardly in an annular groove structure as a whole.

[0009] As an optimal technical solution of the present invention, the sterilizer body also includes a chamber, a front support, and a fixing pin hole. The chamber is welded to the upper end surface of the sterilizer body, the front support is opened inside the chamber, and the fixing pin hole is fixedly connected to the upper wall end surface of the front support.

[0010] As a preferred technical solution of the present invention, the interior of the front support extends downward and is communicated with the interior of the sterilizer body, and two groups of chambers are provided.

[0011] As a preferred technical solution of the present invention, the size of the fixing pin hole is smaller than the size of the air groove, and when the sterilizer body is in an operating state, the fixing pin hole is embedded in the air groove.

[0012] As an optimal technical solution of the present invention, a hole structure is provided at the inner end of the chamber, two groups of support beams are provided, and hole structures are provided on both sides, and the hole structure has the same size as the hole at the side end of the chamber.

[0013] As a preferred technical solution of the present invention, the support beam is fixedly connected to the upper end of the sealing cover, and a rotational connection relationship is established through the rotating shaft connecting block and the shaft structure.

[0014] Compared with the prior art, the present invention provides a self-locking pressure interlocking device with the following beneficial effects:

[0015] The self-locking pressure interlocking device is provided with a movable bolt body, a fixed pin hole, a pin shaft and an air groove. When the equipment is in operation, the operator first needs to close the sealing cover, and then move the movable bolt body to make the pin shaft pass through the side end of the support beam and the chamber. At this time, the air groove provided on the outer end surface of the pin shaft is inserted into the front support inside the chamber. When the sterilizer body is started, steam is generated inside it, and the steam pushes upward through the internally connected front support, and at the same time, the pin shaft is also pushed upward through the air groove. When the pin shaft moves upward, the air groove and the fixed pin hole contact each other and establish a clamping relationship. At this time, since the pin shaft is tightened by the steam, it is in close contact with the fixed pin hole and can no longer move. Through the above-mentioned settings and processes, the equipment can use the steam generated by the sterilizer to perform pressure self-locking on the sealing cover during operation. This pressure self-locking method not only provides further protection for the closure of the sterilizer, but also does not require manual operation. After the sterilizer is started, it automatically tightens and locks, which also avoids the situation where the operator forgets to lock the sealing cover. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 In this embodiment: a self-locking pressure interlocking device includes a sterilizer body 1, a rotating shaft connecting block 2, a support beam 3 and a sealing cover 4. The rotating shaft connecting block 2 is arranged on the upper end surface of the sterilizer body 1, the rotating shaft connecting block 2 is connected to the support beam 3 and supports its rotation, the support beam 3 is arranged above the sterilizer body 1, the support beam 3 carries the installation of the movable bolt 5, and the sealing cover 4 is arranged at the lower end of the support beam 3. The sealing cover 4 seals the interior of the sterilizer body 1;

[0025] A movable bolt 5 is provided at the front end of the support beam 3, and the movable bolt 5 locks the support beam 3;

[0026] The movable bolt body 5 also includes a pin 501 and an air groove 502. The pin 501 is movably connected to the two side end faces of the movable bolt body 5 and adopts the same orientation. The air groove 502 is opened at the side end of the pin 501 and extends inward in an annular groove structure as a whole.

[0027] In this embodiment, the sterilizer body 1 further includes a chamber 101, a front support 102, and a fixing pin hole 103. The chamber 101 is welded to the upper end surface of the sterilizer body 1, the front support 102 is opened inside the chamber 101, and the fixing pin hole 103 is fixedly connected to the upper wall end surface of the front support 102; the interior of the front support 102 extends downward and is connected to the interior of the sterilizer body 1. The chamber 101 is provided with two groups;

[0028] Specifically, the chamber 101 communicated with the interior of the sterilizer body 1 can push the internal steam through the body of the chamber 1 to push up the chamber cover when the sterilizer body 1 is in operation, and at the same time drive the pin 501;

[0029] In this embodiment, the size of the fixing pin hole 103 is smaller than that of the air groove 502. When the sterilizer body 1 is in operation, the fixing pin hole 103 is embedded in the air groove 502. A hole structure is formed at the inner end of the chamber 101. The support beam 3 is provided with two groups of hole structures on both sides. The hole structure has the same size as the hole at the side end of the chamber 101.

[0030] Specifically, by providing a fixing pin hole 103 that is smaller than the air groove 502, the air groove 502 can be more smoothly embedded in the fixing pin hole 103 when the pin shaft 501 is lifted up.

[0031] In this embodiment, the support beam 3 is fixedly connected to the upper end of the sealing cover 4, and a rotational connection relationship is established through the rotating shaft connecting block 2 and the shaft structure.

[0032] The working principle and usage process of the present invention are as follows: when the equipment is in operation, the operator first needs to close the sealing cover 4, and then move the movable bolt body 5 to make the pin shaft 501 pass through the side end of the support beam 3 and the chamber 101. At this time, the air groove 502 opened on the outer end face of the pin shaft 501 is inserted into the front support 102 inside the chamber 101. When the sterilizer body 1 is started, steam will be generated inside it. The steam will push upward through the internally connected front support 102, and will also push the pin shaft 501 upward through the air groove 502. When the pin shaft 501 moves upward, the air groove 502 and the fixed pin hole 103 contact each other and establish a clamping relationship. At this time, since the pin shaft 501 is pressed tightly by the steam and in close contact with the fixed pin hole 103, it can no longer move, thereby reaching a locked state.
