[0041] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0042] In order to adjust the pre-compression elastic force of the torsion spring according to the hardness of the bottle body, as shown in Figure 1 and Figure 2 The present application provides an aircraft lavatory article support, which comprises a side plate 100 and a bottom plate 200, a hollow shaft 1000, a plurality of first torsion springs 900, a plurality of clamping plates 800 and a plurality of groups of inclined blocks 700. Specifically, the side plate 100 and the bottom plate 200 are arranged perpendicular to each other, and are integrally formed by a bending machine in actual production, as shown in Figure 3As shown, the hollow shaft 1000 is fixedly installed on the outer surface of the side plate 100 close to the bottom plate 200, a plurality of first torsion springs 900 are equidistantly sleeved on the outer surface of the hollow shaft 1000, and a plurality of clamping plates 800 are equidistantly rotatably installed on the outer surface of the hollow shaft 1000. One end of the first torsion spring 900 abuts against the lower surface of the clamping plate 800, and the clamping plate 800 is pushed upward by the pre-compression elastic force of the first torsion spring 900, so that in use, the clamping plate 800 pushes the outer surface of the bottle body, thereby fixing the position of the bottle body. A plurality of groups of inclined blocks 700 are arranged on the upper surface of the bottom plate 200, and each group of inclined blocks 700 is arranged as three inclined blocks 700. In use, the bottle body is placed between the three groups of inclined blocks 700, and the inclined blocks 700 are arranged in a triangular shape, with the tips abutting against the outer surface of the bottle body. The three groups of inclined blocks 700 are arranged to be capable of moving close to or away from each other. When the hardness of the bottle body is different, the three groups of inclined blocks 700 are driven to move away from each other at different distances. Because the first torsion spring 900 is coupled with the three groups of inclined blocks 700, the first torsion spring 900 is arranged to adjust the pre-compression elastic force of the first torsion spring 900 when the three groups of inclined blocks 700 move close to or away from each other. When the bottle body is soft, the distance between the three groups of inclined blocks 700 is small, so that the pre-compression elastic force of the first torsion spring 900 is small. When the bottle body is hard, the distance between the three groups of inclined blocks 700 is large, and at this time, the pre-compression elastic force of the first torsion spring 900 is large. Through the above arrangement, the pre-compression elastic force of the first torsion spring 900 can be adjusted when the hardness of the bottle body is different, so as to adapt to different bottle bodies and avoid that the elastic force of the first torsion spring 900 is too large to break the bottle body and damage the sealing property of the bottle body, thereby improving the applicability of the support.

[0043] In order to limit the position of the bottle body and facilitate the clamping plate 800 to tightly press the bottle body, Figure 1 As shown, the first support 300 is fixedly installed on the outer surface of the side plate 100 close to the bottom plate 200, and the second support 400 is fixedly installed on the upper surface of the bottom plate 200. A plurality of first notches 301 are equidistantly formed through the outer surface of the first support 300, and a plurality of second notches 401 are equidistantly formed through the outer surface of the second support 400. The first notches 301 and the second notches 401 form accommodating holes therebetween. In use, the bottle body is placed in the accommodating hole to limit the position of the bottle body, and then the bottle body is tightly pressed in the accommodating hole by the clamping plate 800.

[0044] In order to adjust the pre-compression elastic force of the first torsion spring 900, Figure 1 and Figure 7As shown, the outer surface of the side plate 100 is equidistantly provided with a plurality of openings 101, the other end of the first torsion spring 900 penetrates the openings 101 and is fixedly connected with a second rod 920, the outer surface of the other side of the side plate 100 is equidistantly provided with a plurality of blocks 1200, the outer surface of each of the plurality of blocks 1200 is provided with a guide groove 1210, the second rod 920 is slidingly installed with the inner wall of the guide groove 1210, when the blocks 1200 move upward along the vertical direction, through the cooperation of the second rod 920 and the guide groove 1210, the first torsion spring 900 located at one end of the second rod 920 rotates downward around the hollow shaft 1000 as the rotation center, at this time, because the other end of the first torsion spring 900 is limited, the pre-compression elastic force of the first torsion spring 900 increases, thereby increasing the force of the subsequent clamping plate 800 tightly pressing the bottle body.

[0045] In order to limit the position of the first torsion spring 900 at one end of the clamping plate 800, so that the first torsion spring 900 has a pre-compression elastic force, as shown in Figure 3 、 Figure 6 、 Figure 9 and Figure 10 As shown, the inner wall of the hollow shaft 1000 is slidingly inserted with a square rod 1100, the square rod 1100 is provided in a square shape so that the square rod 1100 cannot rotate, the circumferential outer surface of the hollow shaft 1000 is equidistantly provided with a plurality of sliding grooves 1010, the outer surface of the square rod 1100 is equidistantly fixedly connected with a plurality of supporting blocks 1900, one end of the supporting block 1900 penetrates the sliding groove 1010 and is provided with a mounting groove 1910, the mounting groove 1910 is provided on the lower surface of the supporting block 1900, a clamping block 2000 is provided between the inner walls of the mounting groove 1910, the clamping block 2000 is rotatably installed between the inner walls of the mounting groove 1910 through a rotating shaft, one end of the rotating shaft penetrates the outer surface of the supporting block 1900 and is sleeved with a second torsion spring 2100, one end of the second torsion spring 2100 is fixedly connected with the outer surface of the rotating shaft, the other end of the second torsion spring 2100 is fixedly connected with the outer surface of the supporting block 1900, one end of the first torsion spring 900 close to the clamping plate 800 is fixedly connected with a first rod 910, the lower surface of the clamping block 2000 abuts against the upper surface of the first rod 910, the upper surface of the first rod 910 is provided with a clamping hole 911, when there is no bottle body placed on the upper surface of the bottom plate 200, the clamping plate 800 drives the first torsion spring 900 located at one end of the first rod 910 to move downward through its own gravity, at this time, the first rod 910 will slide from the upper surface of the clamping block 2000, then the clamping block 2000 returns to Figure 9The position of the first lever 910 is limited by the position of the lower surface of the first lever 910, so that the position of the first torsion spring 900 is limited by the first lever 910. In order to release the limitation of the first torsion spring 900, when the square lever 1100 moves along its axis, the clamping block 2000 will slide to the position of the clamping hole 911. Because the size of the clamping hole 911 is larger than that of the clamping block 2000, the clamping block 2000 will slide out of the clamping hole 911. At this time, the first torsion spring 900 is released from the limitation and can drive the clamping plate 800 to press against the bottle body.

[0046] In order to drive the block 1200 to move upward along the vertical direction, as shown in Figure 5 and Figure 6 , a plurality of fourth piston cylinders 1300 are equidistantly and fixedly installed on the outer surface of the other side of the side plate 100.

The fourth piston column 1220 is slidingly inserted between the inner walls of the fourth piston cylinder 1300 and can move up and down along the central axis of the fourth piston cylinder 1300. When the pressure inside the fourth piston cylinder 1300 increases, the fourth piston column 1220 will move upward, thereby driving the block 1200 to move upward.

[0047] In order to couple the first torsion spring 900 with a set of three inclined blocks 700, the pre-compression elastic force of the first torsion spring 900 is adjusted by the mutual movement of the set of three inclined blocks 700 away from each other, as shown in Figure 3 , Figure 4 and Figure 7 , a plurality of limiting grooves are opened on the upper surface of the bottom plate 200.
