Description

Technical Field

[0001] The utility model relates to the technical field of space laboratory equipment, in particular to a human body restraint device and a quality detection device with a limiting function. Background Art

[0002] Body mass is one of the most fundamental physiological indicators of the human body. Stable body mass is a fundamental sign of good health, and changes in body mass reflect the state of human metabolism. In space, measuring body mass is crucial for monitoring astronauts' health and physiological changes, especially during long-term missions. Regular monitoring of body mass not only helps adjust astronauts' diet, exercise plans, and workload, but also allows for the prediction of space illnesses and the design of safety measures.

[0003] Measuring human body mass in orbit also plays an important role in life science research. Accurate body mass measurements can be used to study phenomena such as fluid loss and muscle atrophy in microgravity, as well as to investigate metabolic efficiency and physiological responses in orbit during long-term microgravity.

[0004] While many methods exist for measuring human mass on Earth, they are generally unsuitable for space applications. Measuring mass in orbit requires overcoming challenges such as the microgravity environment, the flexibility of the human body, and the difficulty determining the center of mass during measurement. Therefore, a specialized "space scale"—a mass meter—is required.

[0005] However, when conducting quality inspections, it is necessary to use the standing posture provided by national standards. However, when performing operations, non-standard movements will cause problems in the inspection, and it will be impossible to accurately understand the condition of the human body and make appropriate work arrangements.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0007] The first purpose of the present invention is to provide a human body restraint device with a limiting function, the main problem to be solved is that the human body bracket in the prior art cannot limit the human body, resulting in easy changes in posture during the measurement process, affecting the measurement results.

[0008] The second purpose of the present utility model is to provide a mass detection device, which includes the above-mentioned human body restraint device, four-linkage and mass measuring instrument, which is mainly intended to solve the problem in the prior art that when performing mass detection in a microgravity environment, errors in measurement results are caused by non-standard posture.

[0009] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] The utility model provides a human body restraint device with a limiting function, which comprises:

[0011] bracket body;

[0012] Hand support assembly: The hand support assembly is installed on the top of the bracket body;

[0013] Chest support assembly: The chest support assembly is installed in the middle of the bracket body;

[0014] Hip support assembly: The hip support assembly is installed at the lower part of the bracket body and is installed on the same side as the chest support component.

[0015] Preferably, the hand support assembly includes a left-hand support rod, a right-hand support rod and a connecting rod;

[0016] The left-hand support rod, the right-hand support rod and the end portion of the connecting rod are fixedly connected, the angle between the left-hand support rod and the right-hand support rod is an obtuse angle, and the connecting rod and the bracket body are detachably connected.

[0022] Preferably, the hip support assembly further comprises an abdominal support belt;

[0023] The abdominal support belt is connected to the buttocks support plate, and both ends of the abdominal support belt are detachably connected.

[0029] The human body restraint device is connected to the mass measuring instrument through the four-linkage rod to measure the mass.

[0030] In a microgravity environment, the utility model uses a human body restraint device and a mass measuring instrument based on the principle of linear acceleration in combination. The mass measuring instrument is designed based on the principle of linear acceleration and calculates the user's mass through Newton's second law: F (force) = m (mass) × a (acceleration).

[0031] The quality detection device mainly includes a main unit (constant force mechanism, measurement system), a four-link device, a human body restraint device, a release mechanism and a force sensor cable, wherein the release mechanism and the force sensor cable are both installed on the four-link device.

[0032] During the measurement, the user first secures themselves to the body restraint device as required and then pushes it to the designated position. As the device resets, a constant force (F) provided by a constant force mechanism (composed of a cam, spring, fixed pulley, and wire rope) acts on the user's body, causing them to move in a uniformly accelerated linear motion. A grating distance measuring device measures the user's displacement velocity (v) and time (t) under the constant force. This is used to calculate the acceleration (a = v / t), and given the known constant force, the body's mass (m = F / a) is calculated.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] This utility model provides a human restraint device with a position-limiting function, comprising: a support body; a hand support assembly mounted on the top of the support body; a chest support assembly mounted in the middle of the support body; and a hip support assembly mounted on the lower portion of the support body, on the same side as the chest support assembly. By providing the hand, chest, and hip support assemblies, this utility model limits the user's posture, ensuring that the user maintains a standard posture during testing, facilitating subsequent assignment of appropriate tasks based on the test results.

[0035] The utility model can make real-time adjustments according to the height and weight of the user by matching the first positioning hole, the second positioning hole, the connecting rod and the connecting limiter, and can detect people with a height of 155-183 cm and a weight of 40-80 kg.
