Embodiment Construction

[0024] Below, based on Figure 1 to Figure 4 Examples of the present invention will be described in detail.

[0025] The above-mentioned lockstitch sewing machine 10 includes: a needle drive mechanism 30 for moving the needles up and down, a bottom feed device (not shown) for feeding the cloth of the object to be sewn placed on the needle plate 12 from below in a predetermined feeding direction, The sewing machine housing 20 housing the needle drive mechanism 30 and the lower cloth feeding device, and the upper cloth feeding device 40 which is detachable from the sewing machine housing 20 and feeds the cloth on the needle plate 12 from above along a predetermined feeding direction.

[0026] In the following description, the vertical vertical direction is referred to as the Z-axis direction, and the longitudinal direction of the machine head 23 described later of the lockstitch sewing machine 10 in a horizontally installed state is referred to as the Y-axis direction. The dire...

Abstract

The invention relates to a connection structure of the structuring body of a sewing machine. When a structuring body (81) arranged at one side of a sewing machine (10) is connected with a structuring body (83) arranged at the other side to form relative rotation, the connection structure comprises a rotation support shaft (82) of each structuring body, a clamping part (84) with an inner circular surface in slide contact with the outer circular surface of the rotation support shaft, a rabbet (85) arranged on the outer circular surface of the rotation support shaft or the inner circular surface of the clamping part as well as a soaking part (86) ensuring the infiltration of lubricant and contained inside the rabbet. The connection structure of the structuring body of a sewing machine can simplify the accompanying operation of lubrication.

Description

technical field [0001] The present invention relates to a connection structure of a structure of a sewing machine which does not have a lubricant circulation structure and requires replenishment of the lubricant. Background technique [0002] In general, the sewing machine circulates lubricating oil as a lubricant throughout the interior of the sewing machine casing to lubricate the components that cause internal sliding, [0003] However, for example, the upper cloth feed device that touches and transports the object to be sewn from above, etc., is difficult to ensure the arrangement space of the upper cloth feed device in the sewing machine head, etc., and most of the configuration of the upper cloth feed device is in the The outside of the sewing machine housing is exposed, and in this case, circulation of lubricating oil cannot be performed from the viewpoint of splash prevention. (For example, refer to Patent Document 1) [0004] For this reason, in the above-mentione...
