Liftable mechanism applicable to sewing machine

Abstract

The invention particularly relates to a liftable mechanism applicable to a sewing machine, and is used for adjusting the height of a sewing machine support frame. The liftable mechanism comprises twolifting transmission units and a transmission element for connecting the two lifting transmission units, wherein the two lifting transmission units are respectively arranged inside two sides of the sewing machine support frame; each lifting transmission unit comprises at least two lifting units and at least one transmission unit arranged between the lifting units; each lifting unit comprises a first steering mechanism and a lifting mechanism; the first steering mechanism drives the lifting mechanism to do lifting motion; each transmission unit comprises a fixing part and a second steering mechanism arranged inside the fixing part; the transmission element is arranged between the two opposite second steering mechanisms so as to connect the two lifting transmission units; and the steering mechanisms and the second steering mechanisms are connected through connecting rod elements. The liftable mechanism has the advantages that a sewing machine body can be effectively supported for liftingoperation, and the installation is convenient.

Description

technical field [0001] The invention specifically relates to a liftable mechanism with good load-bearing effect, convenient installation and suitable for sewing machines. Background technique [0002] As a mechanical device with a long history of development, the sewing machine has a wide audience, whether it is used in household or industrial applications. Since the industrial leather in the 18th century, the sewing machine has been developing with the needs of the society. With the continuous research and development of the working principle, the existing sewing machines are getting better and better, and the weaving effect is getting better and better. However, for the sewing machine support structure, it has not been the mainstream research and development direction. Currently, the existing sewing machines are usually fixed structures. Sewing machines with a lifting function only use the cooperation between ordinary holes and bolts to realize the overall lifting. In th...

[0002] As a mechanical device with a long history of development, the sewing machine has a wide audience, whether it is used in household or industrial applications. Since the industrial leather in the 18th century, the sewing machine has been developing with the needs of the society. With the continuous research and development of the working principle, the existing sewing machines are getting better and better, and the weaving effect is getting better and better. However, for the sewing machine support structure, it has not been the mainstream research and development direction. Currently, the existing sewing machines are usually fixed structures. Sewing machines with a lifting function only use the cooperation between ordinary holes and bolts to realize the overall lifting. In this way, for many users, when performing lifting operations, it is necessary to cooperate with the entire sewing unit to disassemble. It takes a lot of manpower to install and lift, and at the same time, the large-quality sewing unit is also likely to pose personal threats to workers during disassembly and assembly.
