Detailed description of the invention
The embodiment of the invention discloses a kind of needle gage regulation locking device, to solve existing apparatus easily because of millDamage causes lock function to lose 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 carried outDescribe clearly and completely, obviously, described embodiment is only the present invention's part embodiment, andNot whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not doingGo out the every other embodiment obtaining under creative work prerequisite, all 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 spiral shellPost 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. Revolve at double-screw bolt 1While turning, 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, openBe provided with button chute 43.
Button 5 is slidably disposed in button chute 43, comprises head 51 and is fixedly installed on 51 ends of headThe connecting rod 52 of face. The sidewall of head 51 and button chute 43 be laminating each other slidably. On connecting rod 52, establishBe equipped 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 thanThe 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 spring8 internal diameter. One end of banking stop 6 is stretched in knob base 2, and it is fixed under the effect of spring 8, to offset with itPosition.
In the needle gage regulation locking device providing at the present embodiment, utilize button 5, banking stop 6, jump ring 7Realize knob base 2 and the locking of feeding apart from knob 2 with spring 8: be not subject to external force at needle gage regulation locking deviceTime, 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 fromKnob base 2, operator can be by swivel feeding apart from knob 2 to drive the needle gage of head of sewing machine 1 insideGovernor motion.
Compared with existing apparatus, the needle gage regulation locking device one hand that the embodiment of the present invention provides can enterLine operate, occupation mode is simple, convenient; Line-locked than utilizing latch to enter in existing sewing machineMode, has replaced some contact with face contact, has solved the wearing and tearing that cause because of friction, and then has caused locking meritThe problem that can lose efficacy.
The reliability of needle gage regulation locking device is provided in order to improve above-described embodiment, further, asShown in Fig. 5, in knob base 2, be provided with spacing ring gear 21, meanwhile, as shown in Figure 7, spacingOn sheet 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 stretchEnter the one end in knob base 2, meanwhile, catch 61 stretches between adjacent two limiting tooths of spacing ring gear 21.
In the time that button 5 does not stress, the catch 61 on banking stop 6 stretches between limiting tooth, stops feeding apart from revolvingButton 4 rotates. And after pressing the button 5, catch 61 departs from from spacing ring gear 21, feeding is apart from knob 4 energyEnough rotation. Utilize coordinating of catch 61 and spacing ring gear 21, avoided because of banking stop 6 and knob base 2Between the relative sliding that causes of frictional force deficiency.
Preferably, cause feeding apart from knob 4 inordinate rotation in one direction for fear of user misoperation,As shown in Figure 5, be provided with block 22 at original position and the end position of spacing ring gear 21.
The height of block 22 is greater than the ultimate range of the spacing ring gear 21 of catch 61 distance, even at button 5 quiltsWhile pressing, catch 61 still can stop that feeding turns over original position or the stop bits of spacing ring gear 21 apart from knob 4Put, thereby avoid the generation of inordinate rotation. It will be appreciated by persons skilled in the art that at the present embodimentInstitute provides in technical scheme, and the original position of spacing ring gear 21 and end position spacing are less, therefore profitRealize stopping of two positions with a block with larger width. And between the two when larger, alsoCan continue to stop to original position and end position 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,Operating personnel determine by the gauge point on head of sewing machine the size that needle gage regulates. And the present embodiment instituteProvide in technical scheme dial 23 is placed on knob base 1, dial 23 in metering needle distanceMotionless, determine that by the numeral on the center line indication dial disc 1 of button 5 and graduation mark needle gage regulates largeLittle, more meet people's thinking habit, do not need thinking, directly the indication point on knob is adjusted to needsScale.
Concrete, in the needle gage regulation locking device providing in the above embodiment of the present invention, connecting ring 41On be 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, make button 5 in upper and lower sliding process moreSmooth-going, improve user's experience and experience.
Further, connecting rod 52 and pilot hole have multiple specific implementation structure. For example, adopt cylindrical barThe connecting rod 52 of 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 toIn assembling process, the assembling of connecting rod 52 and pilot hole, arranges guide surface and can prevent that connecting rod 52 from occurringRotate, 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 machine, is wherein provided with needle gage regulation locking device described above,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 stressesBe and the difference of other embodiment, between each embodiment identical similar part mutually referring to.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field can be realized or useThe present invention. To be aobvious and easy for those skilled in the art to the multiple amendment of these embodimentSee, General Principle as defined herein can be 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 to meet the widest scope consistent with principle disclosed herein and features of novelty.
