Description
Technical field
The invention belongs to field of mechanical technique, especially relate to a kind of sewing-machine foot.
Background technology
Sewing-machine foot is requisite parts in the feed mechanism of Sewing machines, presser feet of the prior art, the distance of needle falling hole and presser feet front end is distant, be prone to deviation when making straight line, when particularly needing to collect many open-wire lines that are parallel to each other of system, in workman's operating process, by virtue of experience constantly adjust with eyes, effort is taken great energy, and has a strong impact on operating efficiency.When making thicker cloth, be prone to the cloth feeding not smooth, cloth is piled up the problems such as card line.
Summary of the invention
The problem to be solved in the present invention provides a kind of sewing-machine foot, especially fits when cloth needs to collect many open-wire lines of system and uses.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of sewing-machine foot comprises pressing plate, depression bar; The upper surface of one end of described pressing plate is provided with boss, described depression bar is hinged on the described boss, the upper surface of the other end of described pressing plate offers respectively pin through hole, crossed beam trunking and groove, described fall pin through hole and crossed beam trunking are positioned at a side of the center line of described pressing plate, opposite side is provided with groove, the described pin through hole that falls is connected with described crossed beam trunking, in described groove, be provided with an end with the guide plate of arc convex, described arc convex is located at the bottom of the front end of described pressing plate, and the other end of described guide plate is hinged on the described boss.
Further, the height of described arc convex is 4-7mm.
Further, the angle of the bottom tangent of described arc convex and horizontal plane is 15 °-20 °.
Further, described guide plate and described pressing plate hinged place are provided with spring.
Further, the bottom of described depression bar has spring to link to each other with described pressing plate.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, there is spring to link to each other between depression bar and the pressing plate, the height of presser feet has certain extendable room, guide plate and pressing plate are articulated and connected, and are provided with spring, when the thickness of cloth not simultaneously, guide plate stretches out the height of groove can be regulated, when cloth is collected open-wire line processed, can locate by guide plate, can reduce the pin error that falls, the pin that falls is even, volume many open-wire lines of system are parallel to each other, and take guide plate as reference, the workman is more easy to operate, increase work efficiency, save production cost, this device has simple in structurely simultaneously, and processing cost is low, the production efficiency advantages of higher.

The specific embodiment
As shown in Figure 1, the present invention includes pressing plate 1, depression bar 2; The upper surface of one end of described pressing plate 1 is provided with boss 7, described depression bar 2 is hinged on the described boss 7, the upper surface of the other end of described pressing plate 1 offers respectively pin through hole 3, crossed beam trunking 4 and groove 5, described fall pin through hole 3 and crossed beam trunking 4 are positioned at a side of the center line of described pressing plate 1, opposite side is provided with groove 5, the described pin through hole 3 that falls is connected with described crossed beam trunking 4, in described groove 5, be provided with an end with the guide plate 8 of arc convex, described arc convex 6 is located at the bottom of the front end of described pressing plate 1, and the other end of described guide plate 8 is hinged on the described boss 7.
The height of described arc convex is 4-7mm.
The bottom tangent of described arc convex and the angle of horizontal plane are 15 °-20 °.
Described guide plate and described pressing plate hinged place are provided with spring.
The bottom of described depression bar has spring to link to each other with described pressing plate.
The course of work of this example: during use, presser feet is installed on the Sewing machines, navigates to suitable position by guide plate 8 at cloth, just can collect easily open-wire line processed.
Above one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
