Description
Technical field
The utility model relates to a kind of regulator, particularly a kind of block form regulator that is used for the Sewing machines feed mechanism.
Background technology
Existing Sewing machines is pushing sewing cloth and stroke when adjusting, send tooth transmission regulator before mainly after the place ahead of Sewing machines and side are provided with one respectively, sending tooth transmission regulator and one, send tooth transmission regulator mainly to comprise final drive shaft after this, after send the tooth transmission group, after send the tooth power transmission shaft, after send the tooth holder, after send the tooth connecting rod, after send tooth, after send tooth beat piece, assembly or mechanisms such as master calibration dish and owner pointer, and before send the tooth transmission group before sending tooth transmission regulator mainly to comprise, before send the tooth power transmission shaft, before send the tooth holder, before send the tooth connecting rod, before send tooth, before send tooth beat piece, before send the tooth dial and before send assembly or mechanism such as tooth pointer.
Yet, existing forward and backward tooth regulator and its transmission mechanism of sending integrated winding mutually, though can adjust the forward and backward shift motion that send tooth, but still there is following problems in actual use: because its forward and backward tooth regulator that send is for separating the diverse location place that is provided with and is individually fixed in the Sewing machines body, when adjusting, can't directly inspect the forward and backward mobile variation of sending tooth, reduced the convenience of its adjustment, suitable loaded down with trivial details when operating and adjust; In addition because it adjusts mode major part is that rotation by its trigger piece directly changes the forward and backward beat orientation of sending tooth beat piece, so the situation of finely tuning for needs often do not reach expected effect, and reduces its practicality; Simultaneously, it is formed assembly major part and only has single effect or function, and quantity and the kind of forming assembly are quite various, can't reduce effectively or saves material cost and processing cost, remains to be improved.
The utility model content
The purpose of this utility model is to provide a kind of block form regulator that is used for the Sewing machines feed mechanism, and it can improve the convenience of user's operation and reach accurate fine setting effect.
To achieve these goals, the utility model provides a kind of block form regulator that is used for the Sewing machines feed mechanism, this Sewing machines has a body, be installed on this internal body one after send tooth beat piece before sending tooth beat piece and one, send after this tooth beat piece and should before send tooth beat piece respectively by a transmission mechanism with one after send tooth to be connected before sending tooth and, this block form regulator comprise send after one the tooth guiding mechanism and with this after send the tooth guiding mechanism side by side configuration one before send the tooth guiding mechanism, send the tooth guiding mechanism to comprise one first sleeve of the described body of cross-under after this, be arranged in this first sleeve inner and corresponding send after described the configuration of tooth beat piece one after send the tooth push rod and be spirally connected and send the tooth screw rod after sending the tooth push rod to do linearly moving one after sending the tooth push rod and make this after this; Should before send one second sleeve that the tooth guiding mechanism comprises the described body of cross-under, be arranged in this second sleeve inner and corresponding described before send the configuration of tooth beat piece one before send the tooth push rod and be spirally connected send before this tooth push rod and order should before send the tooth screw rod before sending the tooth push rod to do linearly moving one; By these rotation adjustment of sending the tooth screw rod, make these send the tooth push rod to drive respectively to send after described tooth beat piece and before send tooth beat piece to do angular deflection, and control send after described tooth and before send the shift motion of tooth.
Beneficial functional of the present utility model is: be set up in parallel anterior position place at the Sewing machines body by the forward and backward tooth guiding mechanism that send, be beneficial to the user and can directly inspect each feed mechanism move variation when adjusting, and then increase and adjust convenience; Utilize and respectively send the tooth push rod and respectively send being spirally connected mutually of tooth screw rod, can make the displacement of respectively sending the tooth push rod be able to be controlled accurately, and be useful on the various adjustment demand; By cooperatively interacting between gear and the alignment pin, when knob, can produce the adjustment sense of touch of noise made in coughing or vomiting noise made in coughing or vomiting (Click), in addition the elasticity of alignment pin is compressed effect by spring bearer plate, can prevent to cause the phenomenon that gets loose because of the vibrations that the body running is produced; Utilize sharing of scale plate not only can save material and processing cost, aspect assembling, also can significantly reduce cost of labor.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.
