Detailed description of the invention
With embodiment, the present invention is described in detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 3, the present invention proposes a kind of sewing machine needle protection device 10, and it includes that support 101, first guides
Bar the 102, second guide post the 103, first support arm 104, sliding connection block 105, connection seat 106 and the second support arm 107.Wherein, prop up
Frame 101 is connected for fixing with head of sewing machine.First guide post 102 and the second guide post 103 are all fastenedly connected at support 101
Bottom.First support arm 104 is slidably connected on the first guide post 102, and one end of the first support arm 104 is used for and needle bar of sewing machine
Connect.Sliding connection block 105 is slidably connected on the second guide post 103, logical between sliding connection block 105 and the first support arm 104
Cross spring 108 to connect.Connect seat 106 include support beam 109 and be arranged on the end plate 110 of support beam 109 upper/lower terminal, wherein,
Support beam 109 and sliding connection block 105 on the direction parallel with the second guide post 103 in being slidably connected, end plate wherein
It is provided with spring 111 between 110 and sliding connection block 105, another end plate 110 is provided with regulation screw 112, regulates screw
The stud end of 112 is against on sliding connection block 105 after end plate 110.One end of second support arm 107 fastens with support beam 109
Connecting, the other end is provided with the pin folder 113 for being enclosed within sewing machine needle.
As shown in Figure 4, Figure 5, in use, the top of support 101 is fastenedly connected the present invention with head of sewing machine 20, and first
The end of support arm 104 is connected by connection member 50 with needle bar of sewing machine 30, and pin folder 113 is enclosed within sewing machine needle 40.Work as seam
During machine of threading operating, needle bar of sewing machine 30 by connection member 50 drive the first support arm 104 do Tong Bu with needle bar of sewing machine 40 upper,
Lower reciprocating motion, by the effect of spring 108, sliding connection block 105 is followed the first support arm 104 and is carried out upper and lower reciprocating motion, and
Sliding connection block 105 drives the second support arm 107 to do upper and lower reciprocating motion by connecting seat 106 so that be positioned at the second support arm 107
The pin folder 113 of end is clamped in the position of the close needle point of sewing machine needle 40 all the time, so that sewing machine needle 40 is in confrontation
The harder material in ground carries out being not susceptible to bending during sewing operation.Additionally, regulation screw 112 can be used to metering needle folder by a small margin
113 installation sites on sewing machine needle 40, when turning adjusting screw 112 makes its precession, the stud end of regulation screw 112
Sliding connection block 105 can be pressed closer, make sliding connection block 105 change with the relative position of support beam 109 (spring 111 simultaneously
Compression) so that pin folder 113 changes with the relative position of sewing machine needle 40；Otherwise, work as turning adjusting screw
112 when making it screw out, and the pressure effect lower slider contiguous block 105 at spring 111 becomes with the relative position of support beam 109
Change, so that pin folder 113 changes with the relative position of sewing machine needle 40.Preferably, connection member 50 is enclosed within sewing machine
Locking on shank 30 and by lock-screw 501, the side of connection member 50 is provided with open slot, open slot is to the first support arm
103 form constraint on the axis direction of needle bar of sewing machine 30.
Further, being connected with nut 114 on regulation screw 112, nut 114 is arranged on regulation screw 112
Between screw head end and end plate 110, the locking that act as of nut 114 regulates screw 112, when by regulation screw 112, pin being pressed from both sides 113
Adjusting to ideal position, fastening nut 114 gets final product adjustment screw 112, thus locking pin presss from both sides the height of 113.
Further, support 101 includes first contiguous block the 115, the 3rd guide post the 116, second contiguous block 117 and locking screw
Bolt 118, wherein, is provided with for the installing hole that be connected fixing with head of sewing machine 20 on the first contiguous block 115；3rd guides
Bar 116 is fastenedly connected the bottom at the first contiguous block 115；Second contiguous block 117 is slidably connected on the 3rd guide post 116,
The side of the second contiguous block 117 is provided with bolt hole；The stud end of clamping screw 118 is through bolt hole and is against the 3rd guide post
On 116.Support 101 can be used to significantly metering needle folder 113 installation sites on sewing machine needle 40, i.e. by adjusting the
Two contiguous blocks 117 position on the 3rd guide post 116 can realize pressing from both sides pin 113 altitude mixture control.
Further, pin folder 113 uses detachably connected with the second support arm 107, in order to change different pin folders 113
To adapt to the sewing machine needle 40 of different model.
Further, spring 108 is provided with expansion link mechanism, the two ends of expansion link mechanism respectively with the first support arm
104, sliding connection block 105 is fastenedly connected；Specifically, expansion link mechanism is by loop bar 120 and the core being slidably connected in loop bar 120
Bar 121 is constituted, and expansion link mechanism is used for preventing spring 108 from bending, thus ensures that spring 108 is to sliding connection block 105
Force direction is effective force direction.
Further, being provided with limited block 122 in the lower end of the second guide post 103, limited block 122 is by tapped through hole even
Being connected to stop screw 123, the stud end of stop screw 123 passes from the end face of limited block 122, spacing after tapped through hole
It is provided with nut 124 between screw head end and the limited block 122 of screw 123, is used for locking stop screw 123.Stop screw 123 is used
In the extreme position that limit slippage contiguous block 105 moves downward, thus the extreme position moving downward the second support arm 107 is carried out
Limit.When sliding connection block 105 moves downward and touch the stud of stop screw 123 under the drive of the first support arm 104
During end, stopping is moved downward under the restriction of stop screw 123 by sliding connection block 105, and the second support arm 107 also stops fortune downwards
Dynamic, needle bar of sewing machine 30 then continues to drive the first support arm 104 to move downward, and spring 108 is stretched simultaneously.Limited block 122 He
Stop screw 123 be provided for protecting some special sewing materials, such as, when object of sewing is mirror surface leather, mirror surface leather
Surface strictly to avoid being encountered by the second support arm 107, otherwise will be left behind indelible trace, have a strong impact on U.S. of mirror surface leather
See.
The present invention only illustrates with above-described embodiment, the structure of each parts, arranges position and to connect be all to have
Changed, on the basis of technical solution of the present invention, all improvement individual part carried out according to the principle of the invention and equivalent
Conversion, the most should not get rid of outside protection scope of the present invention.
