The lower end of the spring mandrel of the utility model is provided with a mounting seat which is fixedly connected with the sterilizer main body; the mounting seat is provided with a through hole, and the spring mandrel penetrates through the through hole and is in sliding connection with the mounting seat.
The outer circumference of spring spindle is equipped with the pressure spring that suits, and the pressure spring end is installed in the mount pad top, pressure spring length unanimous with spring spindle length, the use of spring spindle cooperation pressure spring has reduced electric putter's load, reduces affiliated power.
The lower end of the electric push rod is fixedly connected with the sterilizer main body.
Compared with the prior art, the utility model beneficial effect who has is:
the full-automatic door opening and closing structure of the steam sterilizer adopts the electric push rod to drive the door structure, realizes the automatic opening and closing of the door, and does not need to manually lift the door; the structure of the gear and the rack is used, the transmission is stable, and meanwhile, the function can be realized without increasing much depth of the equipment; the load of the electric push rod is reduced and the power is reduced by matching with the use of a pressure spring; the electric push rod is provided with a travel switch to detect the extension degree of the electric push rod, so that the position of the travel switch on the door body for judging the door switch in the original structure is omitted.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a side view of the present invention.
In the figure: 1. a door body; 2. a spring mandrel; 3. a pressure spring; 4. an electric push rod; 5. a rack; 6. a gear; 7. a door shaft; 8. a sterilizer body; 9. and (7) mounting a seat.
Detailed Description
The invention will be further described with reference to the following examples:
as shown in fig. 1-2, the fully automatic door opening and closing structure of the steam sterilizer of the present invention comprises a door body 1, a gear 6 fixedly connected with one side of the door body 1, and a door shaft 7 rotatably connected with the door body 1 through the gear 6; a spring mandrel 2 which is connected with the gear 6 in a vertical sliding manner is arranged below the gear, and a rack 5 matched with the gear 6 is fixedly arranged at the upper end of the spring mandrel 2; an electric push rod 4 is arranged on one side of the spring mandrel 2 in parallel, and a rack 5 matched with a gear 6 is arranged at the upper end of the electric push rod 4.
The lower end of the spring mandrel 2 is provided with a mounting seat 9, and the mounting seat 9 is fixedly connected to the sterilizer main body 8; the mounting seat 9 is provided with a through hole, and the spring mandrel 2 penetrates through the through hole and is connected with the mounting seat 9 in a sliding manner; the outer circumference of the spring mandrel 2 is provided with a corresponding pressure spring 3, the tail end of the pressure spring 3 is arranged above the mounting seat 9, and the length of the pressure spring 3 is consistent with that of the spring mandrel 2; the lower end of the electric push rod 4 is fixedly connected to the sterilizer main body 8.
The spring mandrel 2 and the electric push rod 4 are respectively fixed with the two racks 5; the gear 6 is fixed with the door body 1 through the door shaft 7, the rack 5 is matched with the gear 6, and the gear 6 rotates when the rack 5 moves up and down; when the gear 6 rotates, the door body 1 simultaneously rotates about the door shaft 7.
