Problems solved by technology

But the space station is a microgravity environment, and the microgravity level is about 10 -3 g. Therefore, the device cannot be turned over by the gravity of the scientific experiment cabinet on the space station, and it is not suitable for use on the space station
And this device structure is complicated, and its open part does not possess self-locking function

Embodiment 1

[0039] Such as figure 1 , figure 2 and Figure 4As shown, a kind of space station scientific experiment cabinet quick-flip positioning locking device of this embodiment includes a pole 33, a hinge and a connecting piece, and the two ends of the pole 33 are respectively rotatably connected with a hinge, and the hinge It is detachably connected with the connecting piece and can form a locking gap for locking the structure to be locked during the connection process.

[0040] Both ends of the pole 33 in this embodiment are respectively hinged to the hinge through a ball joint structure. The ball joint structure is used to rotate and connect with the hinge, which is convenient for installation and can realize multi-angle rotation.

[0041] In this example, if figure 1 , figure 2 and Figure 4 As shown, ball sockets 36 or ball sockets 37 are respectively provided at both ends of the rod 33 , and ball sockets 37 or ball sockets 36 are provided on the hinge. A ball groove 36 ...

Embodiment 2

[0052] Such as image 3 and Figure 5 As shown, a scientific experiment cabinet for a space station of the present embodiment includes the locking device 3, and also includes a plurality of experimental cabinet components, each group of experimental cabinet components includes a plurality of experimental cabinet bodies, and a plurality of experimental cabinet bodies are surrounded by Arranged to form a cylindrical shape, multiple groups of the test cabinet components are arranged in sequence along the axial direction of the cylindrical shape; each of the experimental cabinet bodies is provided with a slide rail on an end surface close to the inner side of the cylindrical shape , the slide rail extends along the circumference of the cylindrical shape; the connecting piece can move in the slide rail, and lock the slide rail during the connection process with the hinge piece. Since multiple groups of experimental cabinet components are respectively arranged in the aircraft cabin...

Embodiment 3

[0058] Such as image 3 and Figure 5 As shown, the present embodiment a kind of fast flipping method of scientific experiment cabinet for space station, comprises the following steps:

[0059] Install the first hinge and the second hinge at the two ends of the pole 33 respectively, and install the first connector and the second connector in the first slide rail 2 of the first experiment cabinet body 1 and the second experiment cabinet respectively. In the second sliding rail 4 of the body 5; connect the first hinge with the first connecting piece until the locking gap between the first hinge and the first connecting piece hugs the track of the first sliding rail 2 noodle;

[0060] Loosen the fixed connection between the second experimental cabinet body 5 and the space station 7, turn over the second experimental cabinet body 5 around the rotating shaft 6 of the adapter, and after the second experimental cabinet body 5 is turned over to the required position, adjust the seco...

Abstract

The invention relates to an overturning positioning locking device, a scientific experiment cabinet for a space station and a quick overturning method. The overturning positioning locking device comprises a support rod, a hinge piece and a connecting piece. The connection is detachable and can form a locking gap for locking the structure to be locked during the connecting process. The scientific experiment cabinet for the space station includes a locking device and multiple sets of experimental cabinet components. Each set of experimental cabinet components includes multiple experimental cabinet bodies. The multiple experimental cabinet bodies are circumferentially arranged to form a cylindrical shape. Multiple sets of experimental cabinets The components are arranged in sequence along the axial direction of the cylinder shape; each experimental cabinet is provided with a slide rail on one end surface close to the inner side of the cylinder shape, and the slide rail extends along the circumference of the cylinder shape; the connecting piece can move in the slide rail , and lock the slide rail during the connection with the hinge. The invention realizes the functions of turning, positioning and locking the scientific experiment cabinet under the condition of microgravity environment, and has simple structure and convenient operation.
