Abstract
Provided is a novel hand wheel protecting cover structure. Three symmetric protruding points are arranged on a round platform of a hand wheel protecting cover. The novel hand wheel protecting cover structure has the advantages that the three symmetrical protruding points which are arranged on the round platform of the hand wheel protecting cover of a direct-drive flush joint machine can be clamped on the inner wall of a hand wheel and not easy to slip, and the problem of the hand wheel protecting cover of an existing direct-drive flush joint machine can be solved. Therefore, the novel hand wheel protecting cover structure is good in use effect, simple in structure, and easy to implement and popularize.
Description
Technical field
The utility model relates to a kind of handwheel cover-protecting structure, and particularly a kind of hand wheel cover-protecting structure belongs to the sewing machine technique field.
Background technology
The type of drive of tradition Sewing machines can be divided into that manpower drives and two kinds of power drives, now, the direct-drive flat bed sewing machine structure that commercially available " New Jack Sewing Machine Co., Ltd. " produces, it is directly installed on the rotor of direct-driven servo motor on the main shaft, in this way, it has reduced the power transmission loss that traditional flat seam machine is done manual work by the driven by motor belt, can be effectively energy-conservation, and vibration is slight and result of use is better; Yet, find in the use that the too level and smooth and easily slippage of the wall of this flat seam machine handwheel protecting cover round platform easily like this brings passive in the work.
Summary of the invention
The purpose of this utility model is: a kind of hand wheel cover-protecting structure is provided, overcomes the existing defects of existing handwheel cover-protecting structure, bring facility in the work for people's use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hand wheel cover-protecting structure, and it is comprised of flat seam machine, main shaft, electric motor end cap, motor stator, rotor hold-down screw, rotor, hold-down screw, handwheel, handwheel hold-down screw, handwheel protecting cover, salient point; It is characterized in that it is provided with the salient point of three symmetries at the round platform of handwheel protecting cover.
The beneficial effects of the utility model: it can be stuck at the salient point of three symmetries that the round platform of direct-drive flat bed sewing machine handwheel protecting cover arranges on the inwall of handwheel and be not easy slippage, it can improve the problem that present direct-drive flat bed sewing machine handwheel protecting cover exists, therefore, result of use is good, it is simple in structure, and very easily implements to popularize.
