Abstract

The present invention relates to an electric sizing tool for determining the ring size. The sizing tool utilizes an electric motor to automatically tighten and loosen a belt hoop ring to measure the thickness of the finger, thus the ring size is determined. Wherein the measured ring size is detected by an encoder and displayed on the display screen to be convenient for the user to operate. A middle gear is meshed with an electric motor gear and contacted by the friction way with a clutch disc. A worm on a worm axle is meshed with a belt hoop rack. A belt hoop strip is fixed on the outer wall of the casing and extended into the casing after the casing is formed into an annular ring.

Description

Be used to measure the finger thickness to determine the electric setting drive device of finger ring size

The present invention generally relates to a kind of sizing tool that is used for measuring the human finger thickness, particularly a kind ofly utilizes motor to tighten up automatically and unclamps the circle of wearing around on the finger, thereby measure the electric setting drive device of finger thickness with the size of determining finger ring.

The applicant's Korean application No.92-3943 has disclosed the example of the manual finger ring sizing tool of a kind of typical case.This finger ring sizing tool is put into finger one cranse earlier and cranse is tightened up on finger, and armrest drives a finger thickness measure portion again, thus measure the size of finger thickness and definite finger ring.But the defective that above-mentioned this sizing tool exists is that manual finger thickness measure portion is very inconvenience concerning the user.

Therefore, one object of the present invention is to provide a kind of and is used for measuring the finger thickness to determine the electric setting drive device of finger ring size, it can not only overcome above defective and can point thickness surely with when determining the finger ring size in amount, utilizes a motor to tighten up automatically simply and unclamps the cranse of wearing on the finger.

For reaching above purpose, the invention provides a kind of electric setting drive device of finger thickness that be used for measuring with definite finger ring size, it comprises: a housing: one is installed in the motor in the housing, and this motor has a motor gear that is fixed on the motor output shaft; One is engaged in the neutral gear of motor gear; One has a clutch disc at the one end and has the worm shaft of a worm screw at its other end; Described worm screw is extended to such an extent that make the side of clutch disc and neutral gear keep rubbing contact in housing; Thereby a sensor that is fixed in the worm shaft middle part makes worm shaft together rotate with sensor; One code translator of swing offset that is used for detecting sensor; One is used for showing the digital indicator of the sensor swing offset that is detected by code translator; One is used for measuring the band of finger thickness, and this band stretches into housing after being fixed in the housing outer wall and forming an annulus housing outside, this band have one with the interior worm shaft of housing on the tooth bar of worm mesh; And a pair ofly being used for changing the motor sense of rotation to tighten up and to unclamp the button of band ring respectively, button is located on the housing top wall.

Above-mentioned and other purposes of the present invention, feature and other advantages can obtain understanding more clearly from the specific descriptions of doing below in conjunction with accompanying drawing, in each accompanying drawing:

Fig. 1 is the view of the structure of an expression electronic finger ring sizing tool of the present invention;

Fig. 2 is the vertical view of the roof of expression finger ring sizing tool of the present invention;

Fig. 3 is the view that concerns between an expression worm screw of finger ring sizing tool of the present invention and the tooth bar;

Fig. 4 is the view of the clutch disc of expression finger ring sizing tool of the present invention;

Fig. 5 is the view of the sensor of expression finger ring sizing tool of the present invention.

As represent that motor 2 is installed in the rectangle housing 1 as shown in Fig. 1 of electronic finger ring sizing tool structure of the present invention.The motor gear 3 that is fixed on the motor output shaft is meshed with neutral gear 4.

Sizing tool comprises that also one is provided with the worm shaft 6 of a clutch disc 5 at the one end.This worm shaft 6 extends longitudinally to such an extent that clutch disc 5 is contacted with a side friction of neutral gear 4 in housing 1.The other end of worm shaft 6 has a worm screw 7.One sensor 8 is located at the middle part of worm shaft 6.In the rotary course of worm shaft 6, the displacement that is produced by its rotation of sensor 8 is detected and is presented on the digital indicator 10 of housing 1 by a code translator 9.

One band 11, the one end is fixed in the outer wall of housing 1, stretches into housing 1 behind the formation one band ring 12 outside housing 1.This hoop bar 11 have with housing 1 in the worm gear or the tooth bar 7 of worm screw 7 engagements.Because the engagement of worm screw 7 and tooth bar 13, rotatablely moving of axle 6 will convert the rectilinear motion of band 11 to.

For to motor 2, code translator 9 and digital indicator 10 power supplies, battery 14 is housed in the housing 1.

Fig. 2 is the roof planimetric map of finger ring sizing tool housing 1.The roof of housing 1 comprises display 10 and pair of

buttons

15 and 16, and the sense of rotation that

button

15 and 16 changes motor 2 is to tighten up respectively and to loosen band ring 12.Demonstrate on the display 10 with " millimeter " or " time " be the finger thickness size through measuring of unit.Utilize a kind of electronic circuit that is used for the Typical Digital display of surveying instrument just can more easily make display 10.

Show in detail clutch disc 5 in Fig. 4, the part of this clutch disc 5 wants more sunken to form a friction portion 17 and a cross-spring part 18 than all the other.This friction portion 17 keeps rubbing contact with the side of neutral gear 4.

As shown in Figure 5, the sensor 8 on the worm shaft 6 is copper dishes of a conduction.The rotation together of sensor 8 and axle 6.At this moment, the swing offset of sensor 8 is detected by code translator 9.

When the finger ring sizing measuring operation of above-mentioned sizing tool, earlier finger is put into band ring 12, press first button 15 then.Therefore motor 2 drives motor gear 3 rotations and and drive neutral gear 4 rotations.Because the friction portion 17 of clutch disc 5 produces rubbing contact with the side of neutral gear 4, so the revolving force of neutral gear 4 passes to the worm screw 7 of worm shaft 6 by clutch disc 5.Therefore worm screw 7 drives the tooth bar 13 of band 11, thereby makes band 11 move and band ring 12 is taken up in finger along the direction of arrow among Fig. 3.At this moment, the swing offset of sensor 8 is detected and is presented on the digital indicator 10 by code translator 9.In the time of can not be mobile again owing to fully tightly snarl finger when band, clutch disc 5 stops its rotation, and neutral gear 4 is only slided on clutch disc 5.

After recording finger thickness size, can press second button, motor 2 unclamps band ring 12 thus just by reverse rotation.Therefore, finger can be extracted out from band ring 12.

As previously discussed, the present invention has supplied a kind of electric setting drive device that is used for determining the finger ring size.Thereby this sizing tool utilizes motor to tighten up automatically and unclamps the band ring and measure the finger thickness and determine the finger ring size.In this sizing tool, thereby the finger ring size through recording is detected and is presented at by a code translator this sizing tool is easy to use.

Though schematic announcement has been done in preferred embodiment of the present invention, those those skilled in the art that only otherwise deviate from the scope and spirit of the present invention that disclose as appended claims, can also make various conversion, increase and replacement.
