Description

Technical Field

[0001] The utility model relates to the field of acupuncture needle processing, in particular to an acupuncture needle fatigue testing device. Background Art

[0002] Acupuncture needles typically consist of a handle, a body, and a tip. During acupuncture treatment, an experienced doctor or operator inserts the tip of the needle into a designated acupuncture point on the human body and, by kneading, twisting, and rotating the handle, transfers force through the body to the tip, stimulating the acupuncture point. During this process, the needle body often bends. However, a practical and reliable acupuncture needle fatigue testing device is currently lacking. Specifically:

[0003] 1. During the use of acupuncture needles, the bending strength of acupuncture needles varies according to the doctor's technique;

[0004] Second, the current situation is that the bending fatigue strength of acupuncture needles has not been tested;

[0005] 3. It is impossible to study and distinguish the differences between acupuncture needles made of different materials, and it is impossible to define the bending test standards for acupuncture needles.

[0006] Therefore, how to solve the above-mentioned deficiencies in the prior art has become the subject to be studied and solved in this utility model. Utility Model Content

[0038] Embodiment: The present invention will be clearly illustrated below with drawings and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0039] The terms used herein are for describing specific embodiments only and are not intended to be limiting of the present invention. Singular forms such as "a," "the," "this," "this," and "the" as used herein also include plural forms.

[0040] See attached Figures 1 to 4 As shown, an acupuncture needle fatigue testing device includes a main unit 1 on which a mounting plate 2 is vertically fixed.

[0041] It also includes a swing block 3 , a sliding block 4 , a first fixing clamp 5 , a fixing block 6 and a second fixing clamp 7 .

[0042] The swing block 3 is rotatably arranged on the front side of the mounting plate 2, and the rotating shaft of the swing block 3 is arranged horizontally, and is driven by a driving mechanism to swing back and forth in the left and right directions; the swing angle, swing frequency, and duration can all be set by the PLC in the host 1.

[0043] The sliding block 4 is slidably positioned on the swing block 3 along the length direction of the swing block 3; thereby, the first fixing clamp 5 can be adjusted by adjusting the sliding block 4, thereby changing the distance between the first fixing clamp 5 and the second fixing clamp 7, thereby adapting to the clamping requirements of different lengths of acupuncture needles 8 and solving the problem of test versatility.

[0044] Before testing, when clamping the acupuncture needle 8, first adjust the sliding block 4 so that it, along with the first fixing clamp 5, slides along the slide rail on the swing block 3. When the distance between the first fixing clamp 5 and the second fixing clamp 7 exactly matches the length of the acupuncture needle 8 to be tested, stop and lock the relative position of the sliding block 4 and the swing block 3. Then, secure the ends of the acupuncture needle 8 with the first fixing clamp 5 and the second fixing clamp 7, respectively, to begin testing.

[0045] The first fixing clamp 5 is fixed on the sliding block 4 , and the first end of the acupuncture needle 8 to be tested is fixed in the first fixing clamp 5 .

[0046] The fixed block 6 is fixed on the front side of the mounting plate 2 and is located below the swing block 3; the second fixed clamp 7 is fixed on the fixed block 6, and the distance between the second fixed clamp 7 and the first fixed clamp 5 corresponds to the length of the acupuncture needle 8 to be measured; the second end of the acupuncture needle 8 to be measured is fixed in the second fixed clamp 7; when the device is not working, the center line between the first fixed clamp 5 and the second fixed clamp 7 overlaps with the center line of the length direction of the acupuncture needle 8.

[0047] The acupuncture needle 8 is a conductor, and is connected in series with the first fixing clamp 5 and the second fixing clamp 7 to form a circuit (see Figure 5 ), the circuit breaker trigger signal of the circuit is used to start an alarm in the host 1.

[0048] Preferably, the driving mechanism is a motor 9 , which is fixed to the back of the mounting plate 2 , and the output shaft of the motor 9 is in transmission connection with the rotating shaft of the swing block 3 .

[0049] Preferably, a control center is built into the host 1, and the control center is electrically connected to the driving mechanism and the alarm.

[0050] Preferably, the host 1 is further provided with a display screen 10 , and the output of the control center is electrically connected to the display screen 10 .

[0051] Preferably, the control center is a PLC, and the alarm is a buzzer (or / and an alarm light). When the acupuncture needle 8 is broken, a trigger signal is sent to the PLC, and the PLC controls the buzzer to emit a prompt sound and shut down the motor 9.

[0052] At the start of the test, the second retaining clamp 7 secures the handle of the needle 8 under test, while the first retaining clamp 5 secures the tip of the needle 8 under test. The PLC activates the motor 9, which in turn drives the swing block 3, along with the sliding block 4 and the first retaining clamp 5, to swing. The swing amplitude ranges from 0-90°, and the swing frequency ranges from 0.5 to 1 second per swing, approximately 60 to 120 times per minute. The number of bends displayed on the display, in response to a breakage alarm, is used for both conventional needle bending fatigue testing and for distinguishing needles made of different materials, thereby establishing different needle bending test standards.

[0053] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
