[0014] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0015] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0016] Example 1

[0017] like Figure 1 As shown, in this embodiment, a micro-satellite mechanical liquid tank stretcher is provided, including a stretching seat 1, a stretching disk 2, a stretching bolt 3 and a limiting unit. The stretching disk 2 is arranged in the liquid tank, and the stretching seat 1 is slidably arranged in the liquid tank. The stretching bolt 3 is rotatably connected to the stretching disk 2, and the stretching bolt 3 passes through the stretching seat 1 and is threadedly sealed with the stretching seat 1. The limiting unit can limit the stretching seat 1.

[0018] In this embodiment, the stretching seat 1, the stretching disk 2, the stretching bolt 3 and the limiting unit are coordinated. When used, the stretching bolt 3 is rotated, and the stretching bolt 3 drives the stretching seat 1 to move, thereby adjusting the volume of the liquid storage tank. Then, the limiting unit is used to fix the position of the stretching seat 1, so that the position of the stretching seat 1 is stable.

[0019] In this way, this structure adopts a simple mechanical design, which reduces the structural requirements for high-precision processing and special materials, reduces manufacturing costs, and can adjust the stretching amount manually or with simple tools without complicated operation and maintenance, thereby improving ease of use. By adjusting the stroke of the stretching bolt 3, the volume of the liquid storage tank can be flexibly adjusted to meet different liquid storage needs. This solution has a simple structure and can achieve liquid management in an effective space while maintaining low cost and ease of operation.

[0020] This structure is specially designed for micro satellites. It has a compact structure and occupies a small space, meeting the space limitation requirements of micro satellites.

[0021] In this embodiment, the stretching seat 1 is used to seal the liquid storage tank and serve as a direct force-bearing component of the stretching action. The material needs to be lightweight and have a certain strength to withstand the pressure of the stretching process.

[0022] The limiting unit in this embodiment includes a spring and a bolt cap 4. The spring is arranged in the liquid storage tank and is connected to the inner wall of the stretching seat 1. The bolt cap 4 is located outside the stretching seat 1 and is threadedly connected to the stretching bolt 3.

[0023] In this embodiment, the limiting unit includes a spring and a bolt cap 4. After the stretching seat 1 is adjusted to an appropriate position, the bolt cap 4 is rotated so that the bolt cap 4 moves and contacts the stretching seat 1. In this way, the spring provides an outward elastic restoring force to the stretching seat 1 from the inside, and the bolt cap 4 limits the stretching seat 1 from the outside, so that the position of the stretching seat 1 is fixed.

[0024] In this embodiment, the outer end of the tension bolt 3 has a bolt head.

[0025] The bolt head in this embodiment is a hexagonal head, or a slot is provided on the bolt head, or a cross slot is provided on the bolt head. In this way, the bolt head is designed to be a shape that is convenient for manual or tool operation, so as to realize the movement of the tension bolt 3.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
