Compared with the prior art, the utility model discloses following profitable effect has:

when the door closing device is used, the door plate is rotated firstly, the door plate rotates by a certain included angle around the planet shaft, so that the extrusion rolling pre-tightening device arranged on the left side (or the right side) of the door plate is well adapted, then the door plate together with the revolving frame rotates around the articulated shaft on the revolving frame on the premise that the extrusion rolling pre-tightening device on the left side (or the right side) is well matched, and when the revolving frame cannot rotate easily, the right side (or the left side) of the door plate is pressed forcibly until the revolving frame can not rotate easily, so that the door plate rotates around the planet shaft, therefore, the extrusion rolling pre-tightening device on the right side (or the left side) of the door plate is adapted under the action of external force, the door closing action is realized, after the door plate is closed, the extrusion rolling pre-tightening device. The cabin door is very simple and fast to operate, and the working strength of workers is reduced.

On the basis of the technical scheme, the utility model discloses can also do following improvement.

Preferably, the extrusion rolling pre-tightening device comprises a clamping block part and an extrusion rolling part, and the clamping block part is provided with a smooth convex part; the extrusion rolling part comprises a roller, a spring, a rotating block and a base, the rotating block is C-shaped, one end of the rotating block is hinged to the base, the other end of the rotating block is fixed on the base through the spring, and the roller is arranged on the rotating block and is positioned in the middle of the rotating block; the clamping block part is fixed.

The beneficial effect who adopts above-mentioned further scheme is that extrusion rolling portion when receiving the collision of fixture block portion, because the effect of spring can dodge around the pin joint, when the bellying on the fixture block portion has been crossed to the gyro wheel, gyro wheel and rotatory piece return when arriving again under the effect of spring, realize the extrusion to fixture block portion, restriction fixture block portion reverse movement, this device simple structure, job stabilization nature is high.

Preferably, the extrusion rolling part or the clamping block part is fixed on the door plate, the clamping block part or the extrusion rolling part is fixed on the door frame, and the clamping block part is matched with the rolling extrusion part.

The beneficial effect of adopting above-mentioned further scheme is that the suitability is high, can cooperate the installation at will.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Fig. 1 is a schematic structural view of the extrusion rolling type locking cabin door of the pressure cabin according to the present invention. The extrusion rolling type locking cabin door of the pressure cabin comprises a door frame 1, a door plate 2, a rotary frame 3 and an extrusion rolling pre-tightening device 5, wherein the rotary frame 3 is hinged on the door frame 1 through a hinge 4, a connecting rod 3-1 is arranged on the rotary frame 3, a planet shaft 3-2 is arranged on the connecting rod 3-1, and the door plate 2 is fixed on the planet shaft 3-2 of the rotary frame 3 through a bearing; the door plate is also provided with a handle 6; the extrusion rolling pre-tightening device 5 comprises a first extrusion rolling pre-tightening device and a second extrusion rolling pre-tightening device which are respectively arranged on the left side and the right side of the door panel and used for limiting the movement of the door panel in a closed state.

As shown in fig. 2, the pressing and rolling pre-tightening device 5 includes a latch portion 56 and a pressing and rolling portion, and the latch portion 56 is provided with a smooth V-shaped groove; the extrusion rolling part comprises a roller 54, a spring 52, a rotating block 53 and a base 51, the rotating block 53 is C-shaped, one end of the rotating block 53 is hinged on the base 51 through a pin shaft 55, the other end of the rotating block is fixed on the base 51 through the spring 52, and the roller 54 is arranged on the rotating block 53 and is positioned in the middle of the rotating block 53.
