Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: the utility model provides a sewing device convenient to cut off line, including sewing machine needle bar body 1, sewing machine needle bar body 1's lateral wall is fixed with spout slide 10, the vertical slidable mounting of spout slide 10's inner wall has slider 14, be connected with second extension spring 15 between slider 14's the top and spout slide 10's the inner wall, slider 14's outer wall fixed mounting has installation axle 7, install the outer wall rotation of axle 7 and install turning block 5, the outer wall of turning block 5 is fixed with triangle shifting block 6, and install axle 7 and run through the center of triangle shifting block 6, the top of turning block 5 is fixed with cutting knife 3 through installation pole 4, sewing machine needle bar body 1 is close to spout slide 10's lateral wall still is provided with and is used for driving

triangle shifting block

6 and 5 pivoted tilting mechanism of turning block.

Tilting mechanism includes mounting panel 8, and mounting panel 8 is fixed and is being close to the lateral wall of spout slide 10 at sewing machine needle bar body 1, and mounting panel 8 is close to the outer wall of spout slide 10 and is fixed with spill toggle block 9, and spill toggle block 9 can be touched when triangle toggle block 6 moves down to drive the upset of triangle toggle block 6 180 degrees.

When the sewing machine needle bar body 1 needs to cut the thread after sewing, push down installation axle 7, thereby drive turning block 5 and triangle shifting block 6 and move down together, and then drive slider 14 and slide down along the inner wall of spout slide 10, second extension spring 15 is elongated simultaneously, turning block 5 still can drive cutting knife 3 through installation pole 4 during the downward movement and move down, when the angle of triangle shifting block 6 touches spill shifting block 9, spill shifting block 9 can stir triangle shifting block 6 and rotate 180 degrees, and then make cutting knife 3 rotate 180, make the cutting edge of cutting knife 3 down, then continue to move down, accomplish cutting to the thread.

After cutting, the sliding block 14 is driven to move upwards under the action of the tension of the second tension spring 15, and then the cutting knife 3 is driven to rotate 180 degrees through the cooperation of the triangular shifting block 6 and the concave shifting block 9, so that the cutting edge faces upwards, and resetting is completed.

Further, still including being used for carrying out spacing locking mechanical system to turning block 5, locking mechanical system includes locking lever 13, and mounting panel 8 is close to the outer wall of locking lever 13 and has seted up the through-hole, and locking lever 13 slidable mounting is in the through-hole, and turning block 5 is close to the outer wall of locking lever 13 and has seted up the lockhole that supplies locking lever 13 male, and the one end that turning block 5 was kept away from to locking lever 13 is fixed with kicking block 11, is fixed with the first extension spring 12 that the cover was established at locking lever 13 outer wall between kicking block 11 and the mounting panel 8.

When needing the cut-off line, through outside pulling kicking block 11, first extension spring 12 can be stretched simultaneously, then kicking block 11 can be drawing locking lever 13 and breaking away from the lockhole of seting up on the turning block 5, remove the locking to turning block 5, after cutting, when the lockhole of seting up on the turning block 5 moved the position of locking lever 13, through the pulling force of first extension spring 12, can insert locking lever 13 in the lockhole on the turning block 5 once more, accomplish the locking, not only the security is high, but also can play the effect of preventing the mistake and touching, prevent to cut 3 auto-eject of sword in the in-process that uses, the security of improvement user.

Further, the outer wall of the mounting shaft 7 is also sleeved with a handle 16, and the mounting shaft 7 can be pushed to move downwards more conveniently through the handle 16.

Further, one end of the lock lever 13 near the rotating block 5 is set to be an oblique angle, and the rotating block 5 can move against the lock lever 13 when moving upwards by setting the oblique angle, so that the automatic locking function is completed.

Further, the outer wall that sewing machine needle bar body 1 is close to cutting sword 3 is fixed with knife pouch 2, cuts the inside that sword 3 inserted knife pouch 2, and the cutting edge that cuts sword 3 up, in the income knife pouch 2, has reached the effect of accomodating to cutting sword 3, and the security is high, can not miss the injury to the people.

Further, the corners of the rotating block 5 are rounded, and the rounded corners can be matched with the bevel on the lock rod 13 more easily.

The working principle is as follows: when the sewing device convenient for cutting the thread is used, when the sewing machine needle rod body 1 needs to cut the thread after sewing is finished, the ejector block 11 is pulled outwards, the first tension spring 12 is stretched, then the ejector block 11 pulls the lock rod 13 to be separated from a lock hole formed in the rotating block 5, the locking of the rotating block 5 is released, then the handle 16 is pressed downwards by pressing the handle 16, the handle 16 presses the mounting shaft 7 and the rotating block 5 and the triangular shifting block 6 to move downwards together, so that the slide block 14 is driven to slide downwards along the inner wall of the chute sliding plate 10, meanwhile, the second tension spring 15 is stretched, when the rotating block 5 moves downwards, the mounting rod 4 can drive the cutting knife 3 to move downwards, the cutting knife 3 is pulled out from the knife sleeve 2, the downward movement is continued, when the angle of the triangular shifting block 6 touches the concave shifting block 9, the concave shifting block 9 can shift the triangular shifting block 6 to rotate 180 degrees, so that the cutting knife 3 rotates 180 degrees, the cutting edge of the cutting knife 3 is downward, and then the cutting knife continuously moves downward to finish the cutting of the wire.

After cutting, can drive slider 14 and upwards remove under the pulling force effect of second extension spring 15, then the cooperation of rethread triangle shifting block 6 and spill shifting block 9, it rotates 180 degrees to drive cutting sword 3, make the cutting edge up, and in the income knife pouch 2, accomplish accomodating to cutting sword 3, the security is high, can not miss the people, oblique angle and the fillet contact of turning block 5 on the locking lever 13 simultaneously, it removes to drive locking lever 13, when the lockhole of seting up on the turning block 5 removed the position of locking lever 13, through the pulling force of first extension spring 12, can insert locking lever 13 in the lockhole on the turning block 5 once more, accomplish the locking, not only the security is high, but also can play the effect of preventing the miscontact, prevent to cut sword 3 auto-eject in the in-process of using, user's security improves.

And the side of the mounting plate 8 faces the user, the cutting blade 3 is moved away from the user during rotation, which can further improve safety.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
