Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a sewing machine walks line and uses auxiliary device, including sliding connection at sewing machine needle bar 1 top and keep away from installation axle 2 of station one side, installation axle 2 axis direction is perpendicular with 1 length direction of needle bar, the one end of keeping away from needle bar 1 at installation axle 2 is rotated and is connected with a sleeve 21, the rigid coupling has the spliced pole 3 that the cross section is the rectangle on the sleeve 21, 3 length direction of spliced pole and installation axle 2 length direction are perpendicular, the one end of keeping away from installation axle 2 at spliced pole 3 can be dismantled and be connected with 3 vertically butt axle 4 of spliced pole, butt axle 4 rotates towards the one end of needle bar 1 and is connected with a fender wheel. When the sewing machine is used, the worker can adjust the position between the blocking wheel 5 and the needle rod 1 through the relative position of the sliding installation shaft 2 and the needle rod 1 according to the width of the required wiring, so that the blocking wheel 5 is abutted to one side of cloth to be sewn, and the sewn stitches are ensured to be on the same straight line.

Referring to fig. 2, a mounting seat 11 is fixedly connected to a needle bar 1 of the sewing machine, a mounting plate 12 is bolted to the mounting seat 11, a hoop 13 with an open end is fixedly connected to the mounting plate 12, a first bolt 131 is connected to the opening of the hoop 13 in a threaded manner, a nut 132 is connected to the first bolt 131 in a threaded manner, the mounting shaft 2 is located in the hoop 13, and the fixing and sliding of the mounting shaft 2 in the hoop 13 can be realized by adjusting the tightness degree of the nut 132 and the first bolt 131, so that the sliding connection between the mounting shaft 2 and the needle bar 1 is realized.

Meanwhile, in order to facilitate the worker to adjust the distance between the catch wheel 5 and the cloth by screwing the position of the nut 132 on the first bolt 131, the nut 132 is selected to be a wing nut 132.

Referring to fig. 1, still rotate on installation axle 2 and be connected with a kicking block 22, kicking block 22 and the one side butt that spliced pole 3 kept away from needle bar 1, the rigid coupling has the joint board 221 tangent with sleeve 21 on the outer circumference of kicking block 22, the rigid coupling has a joint piece 211 in one side that spliced pole 3 was kept away from to sleeve 21 simultaneously, the axis of sleeve 21 is passed through with spliced pole 3's line to joint piece 211, cooperate through joint piece 211 and joint board 221, can fix the relative position of spliced pole 3 on installation axle 2.

Referring to fig. 1 and 2, a mounting hole 222 is formed at an end of the clamping plate 221 away from the connecting column 3, a mounting column 311 is fixedly connected to an end of the connecting column 3 away from the needle bar 1, and a spring 312 is detachably connected between the mounting hole 222 and the mounting column 311. When not needing to use auxiliary device, upwards rotatory fender wheel 5 makes the joint piece 211 butt on the installation axle 2 on the joint board 221, and can avoid keeping off wheel 5 to drive spliced pole 3 and slide down from installation axle 2 under the action of gravity because of the effect of spring 312. When the connector is used again, only the connecting column 3 needs to be rotated downwards to enable the connecting column 3 to be abutted to one end, far away from the clamping block 211, of the clamping plate 221, and the connector can be normally used at the moment. And the connecting column 3 can be switched between two limit positions through the matching relationship of the clamping plate 221 and the clamping block 211 and the clamping plate 221 and the connecting column 3.

Referring to fig. 1, the connection column 3 includes a fixed portion 31 fixed to one side of the sleeve 21 and a sliding portion 32 slidably connected to the fixed portion 31, and one end of the sliding portion 32 away from the fixed portion 31 is connected to the contact shaft 4. A U-shaped groove 313 is formed on one side of the fixing portion 31, a kidney-shaped hole 314 is formed through the inside of the U-shaped groove 313 and one side of the fixing portion 31 departing from the U-shaped groove 313, the sliding portion 32 is located in the U-shaped groove 313, a threaded hole 321 communicated with the kidney-shaped hole 314 is formed through two sides of the sliding portion 32, a second bolt 322 is in threaded connection with the threaded hole 321 through the waist-shaped hole 314, and the relative position of the sliding portion 32 on the fixing portion 31 can be fixed through the second bolt 322.

In summary, when the needle bar fixing device is used, the nut 132 is rotated to loosen the hoop 13, then the mounting shaft 2 is inserted into the hoop 13, and after the relative distance between the catch wheel 5 and the needle bar 1 is adjusted, the nut 132 is rotated to fix the position of the mounting shaft 2 in the hoop 13; then the relative position of the sliding part 32 and the fixing part 31 is adjusted by screwing the second bolt 322, so that the baffle plate can just abut against the needle bar 1; meanwhile, the top block 22 is rotated to enable one end, far away from the clamping block 211, of the clamping plate 221 to abut against the connecting column 3, so that one side of the fabric to be sewn can be fixed through the blocking wheel 5, the fabric is sewn, and the sewing stitches are ensured to be on the same straight line, namely, the distances from the sewing thread to the end part of the fabric are consistent. When the fabric needs to be replaced, the retaining wheel 5 is directly applied with force upwards, the sleeve 21 is rotated on the mounting shaft 2 until the clamping block 211 abuts against the clamping plate 221, and the position of the connecting column 3 can be fixed under the action of the spring 312, so that the retaining wheel 5 is prevented from falling down under the action of gravity. Can direct downward application of force keep off wheel 5 after the cloth of having more changed to make joint piece 211 and joint board 221 break away from being connected, also keep off wheel 5 and fall sewing machine on the surface until spliced pole 3 and joint board 221 keep away from the one end butt of joint piece 211, the staff just can carry out normal sewing work, circulate in proper order.

If the width of sewing thread needs to be adjusted in the course of the work, the staff can directly unscrew the nut 132, and the hoop 13 is in the lax state this moment, and the staff directly pulls the relative position of installation axle 2 in hoop 13 and just can adjust the distance between fender wheel 5 and the needle bar 1 to adjust the width of sewing thread, screw up the nut 132 after the regulation finishes, just can continue normal operation.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
