The specific embodiment
The embodiment of the invention discloses a kind of needle gage regulation locking device, to solve existing apparatus, easily because wearing and tearing cause lock function, lost efficacy, and the loaded down with trivial details problem of using method.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Fig. 3 to Fig. 7, the needle gage regulation locking device that the embodiment of the present invention provides comprises that double-screw bolt 1, knob base 2, screw 3, feeding are apart from knob 4, button 5, banking stop 6, jump ring 7 and spring 8.
Double-screw bolt 1 is connected with the needle gage governor motion in head of sewing machine 01.
Rotating base 2 is sheathed on the outside of double-screw bolt 1, and is fixedly linked with head of sewing machine 01.When double-screw bolt 1 rotation, rotating base 2 keeps static.
Screw 3 is fixed on the overhanging one end of double-screw bolt 1 by feeding apart from knob 4.
Feeding comprises connecting ring 41 and handle ring 42 apart from knob 4, and both are fixed to one another connection, and coaxially arranges.Connecting ring 41 is set in double-screw bolt 1 outside, and feeding is fixedly connected with double-screw bolt 1 apart from knob 4.On handle ring 42, offer button chute 43.
Button 5 is slidably disposed in button chute 43, comprises head 51 and the connecting rod 52 that is fixedly installed on head 51 bottom surfaces.The sidewall of head 51 and button chute 43 be laminating each other slidably.On connecting rod 52, be provided with jump-ring slot.
Banking stop 6, jump ring 7 and spring 8 are all set on connecting rod 52.Wherein, the width of banking stop 6 is greater than the width of head 51; Spring 8 is between banking stop 6 and connecting ring 41, and two ends offset respectively at both; Jump ring 7 is arranged in jump-ring slot, and between adjacent two circles of spring 8, the width of jump ring 7 is not less than the internal diameter of spring 8.One end of banking stop 6 is stretched in knob base 2, and the location that offsets with it under the effect of spring 8.
In the needle gage regulation locking device providing at the present embodiment, utilize button 5, banking stop 6, jump ring 7 and spring 8 to realize knob base 2 and the locking of feeding apart from knob 2: when needle gage regulation locking device is not subject to external force, be arranged on feeding apart from the banking stop 6 in knob 2 under spring 7 effects, keep in touch with knob base 2, prevent that knob base 2 and feeding from relatively rotating apart from knob 2; After pressing the button 5, banking stop 6 departs from knob bases 2, operator can be by swivel feeding apart from knob 2 to drive the needle gage governor motion of head of sewing machine 1 inside.
Compare with existing apparatus, the needle gage regulation locking device one hand that the embodiment of the present invention provides can operate, and occupation mode is simple, convenient; In existing Sewing machines, utilize latch to enter line-locked mode, with face contact, replaced some contact, solved the wearing and tearing that cause because of friction, and then the problem that causes lock function to lose efficacy.
The reliability of needle gage regulation locking device is provided in order to improve above-described embodiment, further, as shown in Figure 5, in knob base 2, is provided with spacing ring gear 21, meanwhile, as shown in Figure 7, on banking stop 6, be provided with catch 61.
Spacing ring gear 21 is axle centered by the spin axis axis of double-screw bolt 1.61 of catch are arranged at banking stop 6 and stretch into the one end in knob base 2, and meanwhile, catch 61 stretches between adjacent two limiting tooths of spacing ring gear 21.
When button 5 does not stress, the catch 61 on banking stop 6 stretches between limiting tooth, stops feeding to be rotated apart from knob 4.And after pressing the button 5, catch 61 departs from from spacing ring gear 21, feeding can be rotated apart from knob 4.Utilize coordinating of catch 61 and spacing ring gear 21, avoided the relative sliding causing because of banking stop 6 and 2 frictional force deficiencies of knob base.
Preferably, for fear of user misoperation, cause feeding apart from knob 4 inordinate rotation in one direction, as shown in Figure 5, at original position and the end position of spacing ring gear 21, be provided with block 22.
The height of block 22 is greater than the ultimate range of the spacing ring gear 21 of catch 61 distance, even when button 5 is pressed, catch 61 still can stop that feeding turns over original position or the end position of spacing ring gear 21 apart from knob 4, thereby avoids the generation of inordinate rotation.It will be appreciated by persons skilled in the art that at the present embodiment and provide in technical scheme, the original position of spacing ring gear 21 and end position spacing are less, therefore utilize a block with larger width to realize stopping of two positions.And between the two when larger, can also to original position and end position, continue to stop respectively by two blocks independent of each other are set.
Further, for the ease of operation, dial 23 is arranged on knob base 1.
In existing apparatus, dial is arranged on knob, and dial can rotate with the rotation of knob, and operating personnel determine by the gauge point on head of sewing machine the size that needle gage regulates.And the present embodiment provides in technical scheme dial 23 is placed on knob base 1, in metering needle distance, dial 23 is motionless, by the numeral on the center line indication dial disc 1 of button 5 and graduation mark, determine the size that needle gage regulates, the thinking habit that more meets people, do not need thinking, directly the indication point on knob is adjusted to the scale needing.
Concrete, in the needle gage regulation locking device providing in the above embodiment of the present invention, on connecting ring 41, being provided with pilot hole, one end of connecting rod 52 is stretched in this pilot hole slidably.
Understandable, pilot hole coordinates with connecting rod 52, makes button 5 more smooth-going in upper and lower sliding process, improves user's experience impression.
Further, connecting rod 52 and pilot hole have multiple specific implementation structure.For example, adopt the connecting rod 52 of cylindrical bar profile, and the guide surface that is parallel to button 5 glide directions is set thereon, meanwhile, in pilot hole, be arranged at another plane that this guide surface fits.Understandable, cylindrical bar is conducive to the assembling of connecting rod in assembling process 52 and pilot hole, guide surface is set and can prevents that connecting rod 52 from rotating, and also just can prevent that button 5 from shaking, and makes the course of action of button 5 more smooth-going.
Understandable, can also adopt cross section be polygonal prism bar as connecting rod 52, now, pilot hole has the shape of cross section identical with connecting rod 52.
The present invention also provides a kind of Sewing machines, is wherein provided with needle gage regulation locking device described above, and it is simple, convenient to use, and has solved the problem that causes lock function to lose efficacy because of wearing and tearing.
In this description, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the present invention.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
