Abstract
The invention relates to a fast needle mounting chuck of a sewing machine. The fast needle mounting chuck of the sewing machine comprises a needle seat for a needle to be installed, wherein a connecting rod is arranged at the top of the needle seat, a groove is formed in the bottom of the needle seat, and two sides of the groove are provided with guiding grooves. Needle plates for needle assembly are arranged in the guiding grooves in a sliding mode, the needle seat at the tops of the needle plates is provided with a needle hole, and a stopping block is arranged in the needle body in a sliding mode. The side of the needle seat is provided with a rectangular hole communicated with the groove, and a pressing plate movably connected through a hinge pin is arranged in the rectangular hole and is movably connected with the needle plates. The pressing plate is in shaft connection with the needle plates. The fast needle mounting chuck of the sewing machine achieves needle installation and dismounting through a lever principle without other auxiliary tools, is high in installation and dismounting speed, capable of being positioned automatically and convenient and fast and improves the efficiency.
Description
Technical field
The present invention relates to Sewing machines field, relate in particular to a kind of sewing machine needle Quick-mounting clamp head.
Background technology
Sewing machine needle is one of accessory indispensable in Sewing machines, and sewing machine needle can be realized making of sewing, and the rigging position of eedle determines whether it easily occurs the faults such as broken needle when work.
Therefore existing sewing machine needle is all connected and fixed by chuck and set bolt, during its installation or removal, all needs to use screwdriver, and installation and removal are more tired, and eedle need to reorientate, more consuming time, affects operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is that a kind of sewing machine needle Quick-mounting clamp head that just can tear pin and dress pin without other aids open is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of sewing machine needle Quick-mounting clamp head, comprise for the needle stand of eedle is installed, described needle stand top is provided with connecting rod, described needle stand bottom is provided with groove, groove both sides are provided with gathering sill, in described gathering sill, slide and be provided with for assembling the needle plate of eedle, on the needle stand at described needle plate top, be provided with pin hole, in pin hole, slide and be provided with block, described needle stand side is provided with the rectangular opening communicating with groove, in rectangular opening, be provided with the pressing plate being flexibly connected by bearing pin, described pressing plate is flexibly connected with needle plate.
Preferably, between described pressing plate and needle plate, by axle, be connected.
Compared with prior art, usefulness of the present invention is: this sewing machine needle Quick-mounting clamp head, by lever principle, is realized the installation and removal of eedle, without other aids, installation and removal velocity ratio is very fast, and can locate voluntarily, convenient and swift, improved efficiency.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is sewing machine needle Quick-mounting clamp head structural representation of the present invention.
In figure: 1, needle stand; 2, connecting rod; 3, pin hole; 4, block; 5, needle board; 6, gathering sill; 7, eedle; 8, rectangular opening; 9, pressing plate; 10, bearing pin.
the specific embodiment:
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of sewing machine needle Quick-mounting clamp head shown in Fig. 1, comprise for the needle stand 1 of eedle 7 is installed, described needle stand 1 top is provided with connecting rod 2, described needle stand 1 bottom is provided with groove, groove both sides are provided with gathering sill 6, the interior slip of described gathering sill 6 is provided with for assembling the needle plate 5 of eedle 7, on the needle stand 1 at described needle plate 5 tops, be provided with pin hole 3, the interior slip of pin hole 3 is provided with block 4, described needle stand 1 side is provided with the rectangular opening 8 communicating with groove, in rectangular opening 8, be provided with the pressing plate 9 being flexibly connected by bearing pin 10, between described pressing plate 9 and needle plate 5, by axle, be connected.
Its concrete occupation mode is as follows, during dress pin, first block 4 is taken off, then eedle 7 is penetrated in pin hole 3, eedle 7 syringe needles are passed from needle board 5, then block 4 is packed in pin hole 3, again pressing plate 9 is pressed down, make to move on needle board 5, the head of eedle 7 is withstood to block 4.While tearing pin open, will be on pressing plate 9 dial, by between eedle 7 heads and block 4 loose from, then take off block 4, eedle is taken out.
This sewing machine needle Quick-mounting clamp head, by lever principle, is realized the installation and removal of eedle 7, and without other aids, installation and removal velocity ratio is very fast, and can locate voluntarily, convenient and swift, has improved efficiency.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
