Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sterilization furnace, in particular to a sterilization furnace door linkage safety unlocking mechanism. BACKGROUND

[0002] At present, as a key equipment in food, medical, biological products and other industries, the sterilization furnace can effectively sterilize and disinfect the articles through high temperature, high pressure or specific wavelength radiation. Among them, the steam sterilization furnace is favored due to its wide application and excellent sterilization effect. The sterilization furnace can effectively kill bacteria, viruses and other microorganisms by placing the articles in a high-temperature steam environment and using the high temperature and pressure of the steam, and is suitable for food processing, medical equipment disinfection and other fields.

[0003] In the safety design of the steam sterilization furnace, considering that the furnace body will be filled with high-temperature and high-pressure gas in the working state, it is crucial to ensure the safety of the furnace door. Therefore, the furnace door is usually designed to rotate and is fixed on the furnace body. The operator needs to carefully rotate the furnace door to achieve its slow opening and closing. The purpose of this design is to allow the high-pressure gas to gradually discharge before the furnace door is completely opened, so that the furnace door can be opened and closed only in the pressure-free state, effectively avoiding the risk of sudden ejection of the furnace door caused by high pressure.

[0004] However, there are obvious limitations in manually controlling the rotation angle of the furnace door to discharge the high-pressure gas. It is difficult for the operator to accurately control the rotation angle of the furnace door, which leads to too small opening gap of the furnace door, affecting the discharge efficiency of the high-pressure gas; on the contrary, if the gap is too large, the risk of direct ejection of the furnace door increases, and the safety hazard is significant.

[0005] In view of the above problems, the present application provides a sterilization furnace door linkage safety unlocking mechanism. Content of the utility model

[0028] The embodiments of the present application provide a sterilization furnace door linkage safety unlocking mechanism, which can solve the problem that the rotation angle of the furnace door is difficult to be accurately controlled by the staff in the related art, and there is a safety hazard.

[0029] Please refer to Figures 1-5The utility model provides a kind of sterilization furnace door linkage safety unlocking mechanism, it includes: fixed plate 1, engagement piece 2, sleeve 3, fixed pipe 4 and transmission part 5, the fixed plate 1 is used to install in one side of furnace door, the engagement piece 2 includes first rack 21, second rack 22 and third rack 23, the first rack 21 is opened in one side of fixed plate 1, the third rack 23 is opened in the other side of fixed plate 1, the second rack 22 is opened on fixed plate 1, the second rack 22 is between first rack 21 and third rack 23, and the two sides of second rack 22 are communicated with first rack 21 and third rack 23 respectively;

[0030] The sleeve 3 is used to install on furnace door support, the fixed pipe 4 is rotationally arranged in sleeve 3, and the transmission part 5 includes connecting shaft 51, gear 52 and handle 53, the connecting shaft 51 is slidably arranged in fixed pipe 4, and the gear 52 and handle 53 are both arranged on connecting shaft 51, and the gear 52 is engaged with first rack 21, second rack 22 and third rack 23;

[0031] In this way, when the furnace door needs to be opened, the gear 52 is located in the first rack 21 at this time, then the staff can rotate the connecting shaft 51 by the handle 53, so that the connecting shaft 51 drives the fixed pipe 4 and the gear 52 to rotate, so that the gear 52 drives the first rack 21 to move through the engagement transmission with the first rack 21, so as to drive the furnace door to rotate through the first rack 21, when the gear 52 enters the second rack 22 from the first rack 21, the gear 52 moves to the last end of the second rack 22, and the gear 52 stops engaging with the second rack 22 at this time, so that the furnace door is only opened by a part, so as to release the pressure in the furnace body;

[0032] Then the staff can pull the handle 53, move the gear 52 in the second rack 22 through the connecting shaft 51, so that the gear 52 moves from the second rack 22 to the third rack 23, so that the gear 52 engages with the third rack 23, so that the staff continues to rotate the handle 53 to drive the furnace door to rotate through the engagement transmission of the gear 52 and the third rack 23, so that the furnace door is completely opened;

[0033] In this way, the staff can only open the furnace door by a part by rotating the handle 53, and then pull the handle 53 to continue to open the furnace door, so that the staff can be forced to operate in two stages through the mechanical structure, so as to avoid the danger caused by the one-time opening of the furnace door, so that the furnace door can be completely opened after the furnace door is opened by a gap for exhaust, and the staff only needs to rotate the handle 53 until it cannot be rotated in the first stage, without manually controlling the rotation angle of the handle 53, so that the operation is convenient, the safety of the furnace door is guaranteed, and the utility model is convenient to use and has high practicability.

[0034] Specifically, in this embodiment, the fixing plate 1 includes a base 11, a mating plate 12, a connecting plate 13, and a positioning component. The base 11 is used to install on the furnace door. A sliding groove 14 is provided on the base 11. The mating plate 12 is located in the sliding groove 14 and mates with it. The mating plate 12 is slidably connected to the sliding groove 14. The connecting plate 13 is provided on the mating plate 12. The first rack 21, the second rack 22, and the third rack 23 are all provided on the connecting plate 13. The positioning component is provided on the base 11 and connected to the mating plate 12 for limiting and fixing the mating plate 12.

[0035] During installation, the operator can slide the mating plate 12 on the base 11 through the sliding connection between the mating plate 12 and the slide groove 14, thereby adjusting the position of the connecting plate 13. The positioning component can then limit and fix the mating plate 12, allowing adjustment of the gap between the second rack 22 and the gear 52. This adjusts the gap for opening and venting the furnace door, making it suitable for installation and use in sterilization furnaces of different specifications. This enhances the applicability and practicality of the device.

[0036] More specifically, the positioning component includes a plurality of bolts 15, all of which pass through the base 11 and are threadedly connected thereto, and the bolts 15 abut against the mating plate 12;

[0037] This allows workers to limit, fix, or unlock the mating plate 12 by tightening the bolt 15, which facilitates the adjustment and positioning of the mating plate 12 and makes it easier to use.

[0038] Preferably, both ends of the connecting plate 13 are provided with limiting blocks 16, and the two sets of limiting blocks 16 are respectively located at the ends of the first rack 21 and the third rack 23 that are far apart from each other;

[0039] In this way, the gear 52 can be limited by two sets of limit blocks 16, preventing the gear 52 from disengaging from the connecting plate 13 when it moves on the first rack 21 and the third rack 23, thus ensuring the stability of the device.

[0040] The groove 14 is convex in shape.

[0041] This prevents the limiting block 16 from detaching from the slide groove 14, ensuring the stability of the connecting plate 13 during installation, thereby enhancing the structural strength of the device and ensuring its performance.

[0042] Furthermore, in this embodiment, guide grooves 41 are provided on both sides of the inner wall of the fixed tube 4, and guide plates 54 are provided on both sides of the connecting shaft 51. The two sets of guide plates 54 are respectively located in the two sets of guide grooves 41 and cooperate with them. The guide plates 54 are slidably connected to the guide grooves 41.

[0043] In this way, the connecting shaft 51 can only slide in the fixed tube 4 by the limiting effect of the sliding connection of the guide plate 54 and the guide groove 41, and can also drive the fixed tube 4 to rotate in the sleeve 3, so that the connecting shaft 51 can rotate while moving horizontally, facilitating the operation of the staff and use.
