Description

Technical Field

[0001] The utility model belongs to the technical field of balance bars, and in particular relates to a balance bar level measurement and calibration device. Background Art

[0002] Functional Movement Screening System (FMS), also known as Functional Movement Screening (FMS), was invented by American physical therapist Cook and is currently widely used in sports injury rehabilitation and physical training. Functional Movement Screening (FMS) originates from functional movement training, and its theoretical support is anatomy, physiology, and neurology. It consists of seven functional movements, including squats, hurdle steps, straight lunge squats, shoulder joint flexibility, straight leg active raises, trunk stability push-ups, and rotational stability, and three exclusion tests. The application of FMS testing can timely discover imbalances and weak links in the body during exercise, improve basic athletic ability, and provide a reference for coaches to develop training plans.

[0003] During the actual test process, the tester has to manually observe a number of posture-related information, which can easily lead to the neglect of the relevant angles of the wooden stick, resulting in the test being inaccurate and objective. Therefore, a balance bar horizontal measurement and calibration device is needed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a balance bar level measurement and calibration device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a balance bar horizontal measurement and calibration device, comprising a rod member, an inner cavity is opened inside the rod member, a first threaded rod and a second threaded rod are rotatably arranged inside the inner cavity, the adjacent ends of the first threaded rod and the second threaded rod are fixedly connected, displacement blocks are threadedly connected on the first threaded rod and the second threaded rod, the lower surfaces of the two displacement blocks are fixedly connected with connecting swivels, the interiors of the two connecting swivels are horizontally rotatably arranged with horizontal balls, the adjacent sides of the two horizontal balls are respectively provided with a laser transmitter and a laser receiver, a slide groove is opened in the inner cavity, the lower surface of the connecting swivel is slidably connected in the slide groove, a handle is arranged at the rotation point of one end of the first threaded rod, an alarm body is arranged on the rod member, and the alarm body is connected to the laser receiver.

[0006] By setting the above structure, when the lifted rod has an unbalanced tilt angle, the horizontal ball will make adaptive rotation adjustment according to the tilt angle of gravity, so that the laser transmitter and laser receiver on one side of the two horizontal balls can maintain horizontal laser transmission and reception respectively. During this period, due to the inclination of the rod, the laser transmitter and laser receiver will be separated from each other's horizontal corresponding positions during the horizontal rotation process, and the alarm body will sound an alarm to notify the personnel to perform calibration and adjustment, thereby helping to ensure the accuracy and objectivity of personnel testing.

[0007] As a preferred implementation, a control body is provided on one side of the rod.

[0008] As a preferred implementation, the laser transmitter, the laser receiver and the alarm body are all connected to the control body.

[0009] As a preferred implementation, the thread directions of the first threaded rod and the second threaded rod are opposite.

[0010] As a preferred embodiment, the handle is circular.

[0011] As a preferred implementation, the laser transmitter and the laser receiver correspond to each other in a horizontal state.

[0012] By setting the first threaded rod and the second threaded rod to have opposite thread directions, when the handle is turned, the handle will drive the laser receiver and the laser transmitter to perform relative displacement through the first threaded rod and the second threaded rod, so that the laser transmitter and the laser receiver can adjust the distance between them through displacement. When the distance is larger, when the rod is slightly tilted, the laser transmitter and the laser receiver can easily cancel the corresponding state, thereby causing the alarm body to sound an alarm. When the distance is smaller, when the rod is slightly tilted, the laser transmitter and the laser receiver will not have too much rotation angle change, and can still correspond to each other, thereby helping to adjust the test degree of horizontal lifting of the rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides a laser transmitter and a laser receiver. When the lifted rod has an unbalanced tilt angle, the horizontal ball will make an adaptive rotation adjustment according to the tilt angle of gravity, so that the laser transmitter and the laser receiver on one side of the two horizontal balls respectively maintain horizontal laser transmission and reception. During this period, due to the tilt of the rod, the laser transmitter and the laser receiver will be separated from each other's horizontal corresponding positions during the horizontal rotation process, so that the alarm body will sound an alarm to notify the personnel to perform calibration and adjustment, thereby helping to ensure the accuracy and objectivity of the personnel test.

[0015] The utility model sets the first threaded rod and the second threaded rod with opposite thread directions. When the handle is turned, the handle will drive the laser receiver and the laser transmitter to perform relative displacement through the first threaded rod and the second threaded rod, so that the laser transmitter and the laser receiver can adjust the distance between them through displacement. When the distance is larger, when the rod is slightly tilted, the laser transmitter and the laser receiver can easily cancel the corresponding state, thereby causing the alarm body to sound an alarm. When the distance is smaller, when the rod is slightly tilted, the laser transmitter and the laser receiver will not have a large rotation angle change, and can still correspond to each other, thereby helping to adjust the test degree of horizontally lifting the rod.

The alarm body 11 is connected to the laser receiver 8. By setting the above structure, when the lifted rod 1 has an unbalanced tilt angle, the horizontal ball 6 will be rotated and adjusted adaptively according to the angle of gravity tilt, so that the laser transmitter 7 and the laser receiver 8 on one side of the two horizontal balls 6 respectively maintain horizontal laser transmission and reception. During this period, due to the inclination of the rod 1, the laser transmitter 7 and the laser receiver 8 will be separated from their corresponding horizontal positions during the horizontal rotation process, so that the alarm body 11 will sound an alarm to notify the personnel to perform calibration and adjustment, thereby helping to ensure the accuracy and objectivity of personnel testing.

[0025] A control body 12 is disposed on one side of the rod 1 .

[0026] The laser transmitter 7 , the laser receiver 8 and the alarm body 11 are all connected to the control body 12 .

[0027] The thread directions of the first threaded rod 2 and the second threaded rod 3 are opposite.

[0028] The handle 10 is circular.

[0029] The laser emitter 7 and the laser receiver 8 correspond to each other in a horizontal state. By setting the first threaded rod 2 and the second threaded rod 3 to have opposite thread directions, when the handle 10 is rotated, the handle 10 will drive the laser receiver 8 and the laser emitter 7 to perform relative displacement through the first threaded rod 2 and the second threaded rod 3, so that the laser emitter 7 and the laser receiver 8 can adjust the distance between them through displacement. When the distance is larger, when the rod 1 is slightly tilted, the laser emitter 7 and the laser receiver 8 can easily release the corresponding state, thereby causing the alarm body 11 to sound an alarm. When the distance is smaller, when the rod 1 is slightly tilted, the laser emitter 7 and the laser receiver 8 will not have too much rotation angle change, and can still correspond to each other, thereby helping to adjust the test degree of horizontally lifting the rod 1.

[0030] The working principle and use process of the utility model are as follows: first, when the lifted rod 1 has an unbalanced tilt angle, the horizontal ball 6 will be rotated and adjusted according to the tilt angle of gravity, so that the laser transmitter 7 and the laser receiver 8 on one side of the two horizontal balls 6 can respectively maintain horizontal laser transmission and reception. During this period, due to the tilt of the rod 1, the laser transmitter 7 and the laser receiver 8 will be separated from each other's horizontal corresponding positions during the horizontal rotation process, so that the alarm body 11 will sound an alarm to notify personnel to perform calibration adjustments. In addition, by setting the first threaded rod 2 and the second threaded rod 3 in opposite thread directions, when the handle 10 is turned, the handle 10 will drive the first threaded rod 2 and the second threaded rod 3 rotate, the first threaded rod 2 and the second threaded rod 3 will drive the laser receiver 8 and the laser transmitter 7 to perform relative displacement through the displacement block 4 and the connecting swivel 5, so that the laser transmitter 7 and the laser receiver 8 can adjust the distance between them through displacement. When the distance is larger, when the rod 1 is slightly tilted, the laser transmitter 7 and the laser receiver 8 can easily release the corresponding state, thereby causing the alarm body 11 to sound an alarm. When the distance is smaller, when the rod 1 is slightly tilted, the laser transmitter 7 and the laser receiver 8 will not have a large rotation angle change, and can still correspond to each other, thereby helping to adjust the test degree of horizontally lifting the rod 1.
