Abstract
Provided is a novel hand wheel protecting cover structure. Three symmetric protrusions are arranged on a round table of a hand wheel protecting cover. The novel hand wheel protecting cover structure has the advantages that the three symmetric protrusions arranged on the round table of the hand wheel protecting cover of a direct-drive lockstitch sewing machine can be clamped in the inner wall of a hand wheel and can not easily disengage, the problems of an existing hand wheel protecting cover of the direct-drive lockstitch sewing machine can be solved, the using effect is good, the structure is simple, and implementation and popularization are easy.
Description
Technical field
The present invention relates to a kind of handwheel cover-protecting structure, particularly a kind of hand wheel cover-protecting structure, belongs to 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 main shaft, in this way, it has reduced the power transmission loss that traditional flat seam machine is done manual work by driven by motor belt, can be effectively energy-conservation, and vibration is slight and result of use is better; Yet, in use, find 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 work.
Summary of the invention
The object of the invention is to: a kind of hand wheel cover-protecting structure is provided, overcomes the existing above-mentioned defect of existing handwheel cover-protecting structure, bring the facility in work to people's use.
The technical solution adopted for the present invention to solve the technical problems 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 three symmetrical salient points on the round platform of handwheel protecting cover.
Beneficial effect of the present invention: three symmetrical salient points that it arranges on the round platform of direct-drive flat bed sewing machine handwheel protecting cover can be stuck on the inwall of handwheel and be not easy slippage, it can improve the problem that current 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 universal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Shown in figure: 1, flat seam machine; 2, main shaft; 3, electric motor end cap; 4, motor stator; 5, rotor hold-down screw; 6, rotor; 7, hold-down screw; 8, handwheel; 9, handwheel hold-down screw; 10, handwheel protecting cover; 11, salient point.
The specific embodiment
A cover-protecting structure, it by: flat seam machine (1), main shaft (2), electric motor end cap (3), motor stator (4), rotor hold-down screw (5), rotor (6), hold-down screw (7), handwheel (8), handwheel hold-down screw (9), handwheel protecting cover (10), salient point (11) form; On the round platform of handwheel protecting cover (10), be provided with three symmetrical salient points (11).
