Abstract
The utility model discloses a hand wheel protecting cover structure. A tapered frustum is arranged on a round table of a hand wheel protecting cover of a direct-driven lockstitch sewing machine, and thus the frustum of the protecting cover is not prone to come off when clamped in the inner wall of a hand wheel. The hand wheel protecting cover structure can solve the problems of an existing hand wheel protecting cover of the direct-driven lockstitch sewing machine. Consequently, the hand wheel protecting cover structure is good in utilization effect, simple in structure, and quite easy to popularize.
Description
Technical field
The utility model relates to a kind of handwheel protecting cover, and particularly a kind of handwheel 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 handwheel cover-protecting structure is provided, and it can improve the existing defects of above-mentioned handwheel protecting cover, from then on can bring the facility in the work.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of handwheel 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, frustum; It is characterized in that it is arranged to frustum with tapering at the round platform of handwheel protecting cover.
Beneficial effect: it is provided with frustum with tapering at the round platform of direct-drive flat bed sewing machine handwheel protecting cover, in this way, the frustum card of protecting cover is placed in the inwall of handwheel and is 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, and it is simple in structure, and very easily implements to popularize.
