The specific embodiment

Relevant the utility model is for reaching above-mentioned purpose, and technological means that is adopted and effect thereof enumerate possible embodiments now, and conjunction with figs. are described as follows:

At first, see also Fig. 1, Fig. 2 and Fig. 3, the utility model is primarily aimed at special long-armed pattern Sewing machines (LONG ARM QUILTING MACHINE) and designs manual driving-controlling device, to carry out sewing special large-scale, thick and fluffy multilayer cloth or leather.Sewing machines as shown in the figure, the last horn 11 of its body 1 is provided with frame head apparatus 13 and relative needle plate 17 with following horn 12, and in time rule belt 142,152 driving main shaft 15, power transmission shaft 16 rotate via associated pulley 141,151,161 with motor 14, suture needle 131 and suture (figure does not show) thereof that the main shaft 15 of top drives frame head apparatus 13 up and down reciprocatingly move with

presser feet

132, and 18 rotations of line device are colluded in power transmission shaft 16 drives in below, to collude suture and the bottom line of shuttle of system suture needle 131, buy car in installments and stitch special large-scale and thick and fluffy and so on working substance.

To preferred embodiment shown in Figure 7, the main controlled interlock of the manual driving-controlling device of the utility model is in main shaft 15 outer circumferential sides of last horn 11 inside of Sewing machines at Fig. 1.As shown in the figure, manually driving-controlling device includes: a driven gear 2 central shaft holes 21 socket interlocks are in main shaft 15 outer peripheral edges, and cooperate hold-down screw 23 to fix (consulting Fig. 7) via screw 22 interlockings radially.Axostylus axostyle 54 ends are fixed in 31 sockets of one driving gear, 3 central shaft holes, and cooperate hold-down screw 33 to fix via screw 32 interlockings radially, make driving gear 3 correspondences towards driven gear 2.One holder 4 is arranged at front, the outside or top (the consulting Figure 11) of horn 11 on the Sewing machines, and locatees via through hole 46 interlocking fixing holes 112 with bolt 47.Axostylus axostyle 54 ends are fixed in 51 sockets of one manual runner 5 central shaft holes, and cooperate hold-down screw 53 to fix via screw 52 interlockings radially, axostylus axostyle 54 is reached the through hole 111 of going up horn 11 by the axis hole 41 that outer past interior activity is placed through holder 4, to engage interlock driving gear 3.

In the design of the manual driving-controlling device of the utility model, the axostylus axostyle 54 of manual runner 5 has more laborsaving operating position that advances inwardly, make driving gear 3 as Fig. 9 and bridle joint driven gear 2 shown in Figure 10, further, reach manual laborsaving adjustment sewing advance and retreat pin with manual runner 5 rotating shaft rods 54, driving gear 3, driven gear 2 and main shaft 15.In addition, the axostylus axostyle 54 of manual runner 5 has a separation point position of withdrawing from relatively outwardly, rotate the centrifugal force of moment and the elastic force of compression spring 57 once more by driven gear 2, make driving gear 3 can break away from driven gear 2 as shown in Figures 7 and 8 outward, thereby when 15 rotations of motor 14 driving main shaft, avoid interlock to driving gear 3, preventing to mesh vibrating noise, and improve the sewing operational security.

Go on to say the manual driving-controlling device of the utility model Sewing machines, to shown in Figure 10, the axis hole 41 of holder 4 cooperates and contains two axostylus axostyles 54 of being separated by

radial loop groove

55,56 and run through as Fig. 6, two radially 55,56 of annular grooves set operating positions, separation point positions relatively.And holder 4 is provided with a screw 42 radially that communicates with axis hole 41, to insert a steel ball 43, a spring 44 and an adjustment bolt 45 in regular turn, for the strength of adjusting setting spring 44, make spring 44 promote steel ball 43 parts and be resisted against one of them radially

annular groove

55,56 location.As shown in Figures 7 and 8, holder 4 is positioned radially annular groove 55 with steel ball 43, to set the separation point position.And among Fig. 9 and Figure 10, then with another radially annular groove 56 cooperate steel balls 43 to be positioned to operating position.Again, axostylus axostyle 54 is set radially annular groove 56 degree of depth of operating position greater than radially annular groove 55 degree of depth of setting the separation point position, to have bigger positioning action.

Please consult Fig. 5 again to the manual driving-controlling device of Sewing machines shown in Figure 9, driving gear 3 and driven gear 2 are made as the helical gear that axial line intersects each other, with the interlock that joins each other, and the number of teeth of driving gear 3 makes driving gear 3 can pass through the through hole 111 in last horn 11 outsides less than the number of teeth of driven gear 2.In preferred embodiment, manually axostylus axostyle 54 peripheries of driving-controlling device are equipped with compression spring 57 between holder 4 and manual runner 5, and the manual runner 5 of outer in the past pushing and pressing makes driving gear 3 break away from driven gear 2 (consulting Fig. 7).And axis hole 41 1 ends of holder 4 are provided with an elastic washer 48, with against driving gear 3 opposite ends, avoid driving gear 3 collision holders 4 to cause noise.

The manual driving-controlling device of the utility model is fit to certain engages drive machine spindle, manually to adjust sewing advance and retreat pin, and can break away from machine spindle and power automatically fully, improve the sewing operational security, avoid vibrating noise, push and use and the more laborsaving convenience of rotating operation, more durable in use.

Above illustrated embodiment is only used the utility model for convenience of description, and is not in a limitative way, not from the utility model spirit category, the those skilled in the art various simple and easy variation and the modification that can do, all must include in the scope of claims.
