Adjustable sewing machine presser feet mounting bracket
Technical field
The present invention relates to sewing machine accessory field, especially a kind of adjustable sewing machine presser feet mounting bracket.
Background technology
Existing sewing machine presser feet needs when changing to separate overall for presser feet with sewing machine pole, and then loads onto the presser feet of coupling. This kind of presser feet dismounting trouble, and the cost of manufacture of presser feet is also high. Meanwhile, the alignment device of straight line sewing is also lacked in use. Some presser feet carries the alignment function of straight line sewing, and does not have on some presser feet, can processing be made troubles.
Summary of the invention
It is an object of the invention to provide a kind of adjustable sewing machine presser feet mounting bracket being applicable to mating with various presser feet.
What the present invention solved is that existing sewing machine presser feet needs when changing to separate overall for presser feet with sewing machine pole, and then loads onto the presser feet of coupling. This kind of presser feet dismounting trouble, and the cost of manufacture of presser feet is also high. Meanwhile, the problem of the alignment device of straight line sewing is also lacked in use.
The present invention solves the technical scheme of its technical problem employing: the present invention comprises rack body and guide rod mount pad; One sidewall of described rack body is provided with vertical installation groove, and another sidewall is carved with fixed orifices; Described installation groove and fixed orifices are mutually through; The front end of described rack body is provided with lug, and described lug is provided with blocked hole, and the inside of lug is provided with torsional sprig, and the aperture place of described blocked hole is provided with a gear sheet, and the other end of described gear sheet is connected to torsional sprig place; The rear side of described rack body is provided with one chute, and described guide rod mount pad utilizes adjusting bolt to be installed on chute; The upper surface of described guide rod mount pad is provided with threaded hole, and threaded hole place is provided with standing bolt; The both sides of described guide rod mount pad are provided with through guide rod open holes; It is installed with linear guide in described guide rod open holes.
The invention has the beneficial effects as follows: the present invention, as the mounting bracket of presser feet, can be installed on the presser feet pole of sewing machine, and the pin apparatuses that presser feet is provided with can be used for presser feet to be connected with presser feet mounting bracket, and install rapidly firm again. Being provided with guide rod mounting blocks at the rear of rack body in addition, guide rod mounting blocks can regulate height along chute, and is convenient to install linear guide, can play the effect of guiding straight line in sewing process.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the present invention comprises rack body 1 and guide rod mount pad 3. One sidewall of rack body 1 is provided with vertical installation groove 1-1, and another sidewall is carved with fixed orifices 1-4. Groove 1-1 and fixed orifices 1-4 is installed mutually through. And groove 1-1 is installed through the top of rack body 1 and bottom.
The front end of rack body 1 is provided with lug 1-3, and lug 1-3 is provided with blocked hole 1-2, and the inside of lug 1-3 is provided with torsional sprig 6, and the aperture place of blocked hole 1-2 is provided with a gear sheet 7, and the other end of gear sheet 7 is connected to torsional sprig 6 place. Torsional sprig 6 utilizes steady brace 8 to be fixed on lug 1-3. The rear side of rack body 1 is provided with one chute 1-5.
Guide rod mount pad 3 utilizes adjusting bolt 5 to be installed on chute 1-5. The upper surface of guide rod mount pad 3 is provided with threaded hole 3-1, and threaded hole 3-1 place is provided with standing bolt 2. Linear guide 4 it is installed with in screw thread 3-2. Linear guide 4 comprises construction section 4-1 and guide section 4-2. Construction section 4-1 utilizes standing bolt 2 to be installed on guide rod mount pad 3. Guide section 4-2 contacts with sewing machine table, and linear guide 4 locating distance is determined from the height of sewing machine table by the distance of guide rod mount pad 3 movement on chute 1-5. Chute 1-5 can play good regulating effect.
Gear sheet 7 is located at the aperture place of blocked hole 1-2, can effectively coordinate the installation of pin on sewing machine presser feet, and it is convenient to change presser feet, as long as tapping into along gear sheet 7 card, enter after blocked hole 1-2 completely until pin, gear sheet 7 can spring back to original position under the action of the spring, achieves the installation of presser feet like this and fixes. And, utilize the present invention can realize the installation of multiple presser feet. The straight line sewing processing of cloth can be realized again, prevent away line crooked.
