Abstract
The present invention relates to a kind of inner diameter measuring device of prosthetic socket.Receptive cavity inner diameter measurement product in actual applications measurement size error is comparatively large, and lateral dimension is bigger than normal, carries inconvenience.The present invention is provided with rotating disc, and rotating disc is connected with chi dish by turning axle, and chi dish inner circumferential arranges tape measure; The code-disc of rotating disc and scrambler is coaxially connected and fixed, and the code reader in scrambler answers code-disc rotate and export square-wave signal, and transfers to single-chip microcomputer, is shown after data processing by display screen.Present invention incorporates machinery and microelectronics two kinds of technology modes, carry out the measurement of receptive cavity transversal section internal diameter size by the longitudinal degree of depth of difference, rational in infrastructure, convenient operation and carrying, data operation is rapid, and not only measuring accuracy is high, and data reliably and be easy to carry.
Description
Technical field
The invention belongs to rehabilitation engineering technical field, be specifically related to a kind of inner diameter measuring device of prosthetic socket.
Background technology
Receptive cavity is of paramount importance component in prosthetic product, and in artificial limb manufacturing process, need to measure the internal diameter of the irregular tubbiness cavity holding patient's deformed limb, the whether suitable of receptive cavity is the key factor determining prosthetic product quality.In order to improve the quality level of China's prosthetic product, before and after 1980, introduced state-of-the-art internal diameter chi at that time from Germany, structure belongs to mechanical screw type, and so far only this single variety is still continuing to continue to use in decades.After this, artificial limb manufacturing technology field all rarely has report to the new kind of this device and technology.After 2004, domestic existing similar products come out, but this series products exists some technological deficiencies in actual applications: one is because its version limit, and measurement unit is with a centimetre setting, and measurement size error is larger; Two is that depth measurement pin can not adduction, and lateral dimension is bigger than normal, carries inconvenience.
Summary of the invention
The object of this invention is to provide a kind of inner diameter measuring device that can effectively improve measuring accuracy, use prosthetic socket more easily.
The technical solution adopted in the present invention is:
An inner diameter measuring device for prosthetic socket, is characterized in that:
Described device is provided with rotating disc, and rotating disc is connected with chi dish by turning axle, and chi dish inner circumferential arranges tape measure;
The code-disc of rotating disc and scrambler is coaxially connected and fixed, and the code reader in scrambler answers code-disc rotate and export square-wave signal, and transfers to single-chip microcomputer, is shown after data processing by display screen.
Described turning axle periphery is provided with axle sleeve, arranges pit gauge outside axle sleeve, and on pit gauge, cover has sliding sleeve, sliding sleeve is provided with folding pin and the set lever for sliding sleeve location.
Described chi dish and tape measure grafting are also placed in chi box.
The present invention has the following advantages:
Present invention incorporates machinery and microelectronics two kinds of technology modes, carry out the measurement of receptive cavity transversal section internal diameter size by the longitudinal degree of depth of difference, rational in infrastructure, convenient operation and carrying, data operation is rapid, and not only measuring accuracy is high, and data reliably and be easy to carry.

Embodiment
Below in conjunction with embodiment, the present invention will be described in detail.
The inner diameter measuring device of a kind of prosthetic socket of the present invention, it is a kind of novel electronical display internal diameter chi, for measuring the internal diameter of the irregular receptive cavity of cavity shape, the technological means adopting machinery and microelectric technique to combine, improves the degree of accuracy of measurement mechanism and the degree of convenience of use.
As shown in Figure 1, measurement mechanism is provided with the rotating disc 1 of level to concrete structure, and be connected with the chi dish 14 of level below rotating disc 1 by vertical turning axle 4, chi dish 14 inner circumferential arranges tape measure 13, and chi dish 14 and tape measure 13 grafting are also placed in chi box 15.Turning axle 4 periphery is provided with axle sleeve 12, arranges pit gauge 8 outside axle sleeve 12, pit gauge 8 EXT scale in centimetre, on pit gauge 8 cover have sliding sleeve 9, sliding sleeve 9 is provided with folding pin 10 and for sliding sleeve 9 locate set lever 11.For improving the portable degree of device and degree easy to use, under the prerequisite ensureing instruction, adopting working of plastics to make each parts as far as possible, good insulativity can also be reached, reduce cost of manufacture.
See Fig. 2, rotating disc 1 is coaxially connected and fixed with the code-disc of scrambler 5, when rotating disc 1 rotates, code-disc also can simultaneously with same angular turn, code reader in scrambler 5 answers code-disc rotate and export square-wave signal, and transfers to single-chip microcomputer 3, calculates in single-chip microcomputer 3 to reception data, obtain internal diameter numerical value after data processing, shown by display screen 2.Wherein, display screen 2, single-chip microcomputer 3, scrambler 5 are all arranged on below rotating disc 1 and locate, and form the core control portions at top, this part is also provided with power switch 6, charging jacks and restorer 7 in addition.The model of above-mentioned scrambler 5 is HKT3004-H01G1-500BZ3-5E-L, and the model of single-chip microcomputer 3 is AT89S51.
When fathoming, set lever 11 of outwarding winding, sliding sleeve 9 is released and can moves up and down along pit gauge 8, moves to reservation when fathoming, sliding sleeve 9 lower edge is aimed at the numerical scale line on pit gauge 8, screws set lever 11 pairs of sliding sleeves 9 and position.
When measuring internal diameter, turn on the power switch 6, display screen 2 starts, initial " 0 " bit line (232mm) of calibration.Chi dish 14 is put into and accepts cavity, folding pin 10 is launched, in level, be butted on receptive cavity ischium platform place, rotate turning axle 1, drive rotation axis 4 and chi dish 14 to rotate, also drive the code-disc of scrambler 5 to rotate.When chi dish rotates, tape measure decontrol until with receptive cavity contact internal walls after, stop operating turning axle 4, the angle that turning axle 4 turns over during this period is exactly the angle that the code-disc of scrambler 5 turns over, code reader in scrambler 5 answers code-disc rotate and export square-wave signal, and transfers to single-chip microcomputer 3, calculates in single-chip microcomputer 3 to reception data, obtain the internal diameter numerical value of this depth after data processing, shown by display screen 2.
Content of the present invention is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading instructions of the present invention to any equivalence that technical solution of the present invention is taked, is claim of the present invention and contains.
