Detailed Description
The invention will be further described with reference to specific embodiments below:
as shown in fig. 1-4, a casing of a flat sewing machine comprises a machine head 11, a machine base 12 and a cross beam 13, wherein a gap 110 is formed in the back side of the machine head 11, a protective cover 5 is arranged on the outer side of the gap 110, the side wall of the protective cover 5 is a plane, and a connecting piece 4 is arranged on the side wall of the protective cover 5; in the technical scheme, the notch 110 is used for connecting a component structure of the lockstitch sewing machine to the external motor 2 from the inside of the shell, the component structure which can be applied here can be an upper feeding structure 3 of the lockstitch sewing machine, and comprises an upper feeding fork crank 30, an upper feeding front crank 32, an upper feeding swing shaft 33, an upper feeding swing rod 34, an upper dental articulator 35 and an upper feeding tooth 36, the composition of the upper feeding structure 3 is mature prior art, and no description is given here, the motor 2 is mounted on the back side of the machine head 11 through a connecting piece 4, the distance between the motor 2 and a controlled structure is shortened, and a part of space in the machine base 12 is simplified, so that possibility is provided for improving the lifting performance of the lockstitch sewing machine and improving other mechanisms, for example, a presser foot mechanism of the lockstitch sewing machine which is lifted in the application number 202120636546.1 is added, and a redundant space needs to be left in the machine base 12 part of the shell 1; go up feeding structure 3 and motor 2's connection process simultaneously and wear out the casing, do not receive the protection of casing, have potential safety hazard and fault risk, for this reason corresponding outwards extend along the breach and form 5 alignments of safety cover and protect to the lateral wall of safety cover 5 also can provide one side stationary plane for connecting piece 4 more, makes motor 2 installation firm more stable.
Furthermore, the back side of the cross beam 13 is provided with the mounting groove 6, in the technical scheme, the motor 2 and the upper feeding structure 3 are not connected from the machine base 12 to the machine head 11 any longer, and the motor and the upper feeding structure are directly arranged on the machine head, so that the space for arranging a transmission long shaft in the cross beam 13 is saved, the mounting groove 6 can be inwards arranged on the cross beam 13, the structure can be simplified, and the space is reduced.
