Detailed description of the invention
For making that architectural feature of the present invention and effect of reaching are had and further understand and be familiar with, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figures 1 to 4, a kind of crosspointer shank, comprise shank handle 1 and shank cover 2, shank handle 1 is hollow structure, the end of this shank handle 1 is provided with threaded connection hole 11, can withstand the spring of shank handle 1 inside by add nut in this threaded connection hole 11, to ensure the normal utilization of crosspointer shank on embroidering machine.The front end of shank handle 1 is provided with Hang Xiu pin department of assembly 3, shank handle 1 is cylindrical, and the cross section of department of assembly 3 is semicircle, and the arcwall face of department of assembly 3 is mutually concordant with the side of shank handle 1, and shank handle 1 and department of assembly 3 structure that is formed in one, its moulding material is 20CrMo.The hardness at body of the present invention position can reach 64 °-68 ° of HRC, the hardness of head can reach 50 ° of HRC, all be much higher than the hardness of common shank, its bend resistance intensity is greater than 40 ㎏/100 ㎜ simultaneously, therefore the present invention has good physical property, it has more impulsive force and the saturating power of thorn compared to common shank, and its service life and result of use can be more outstanding.
Parallelly on the parallel surface of department of assembly 3 be provided with two and embroider the mounting groove 31 that matches of pin 5 with sewing with long stitches, mounting groove 31 comprises the first mounting groove 311 and the second mounting groove 312, this first mounting groove 311 and the second mounting groove 312 are symmetrically set on the parallel surface of department of assembly 3, and the length of the first mounting groove 311 is greater than the second mounting groove 312.Can make thus the present invention can be fixedly connected with two different sewing with long stitches of extension elongation and embroider pin 5, to meet the need of work of crosspointer embroidering machine.
Shank cover 2 is bar shaped, and shank overlaps 2 the through hole 21 matching with department of assembly 3 that is axially arranged with, and shank cover 2 is socketed with department of assembly 3, and the length of shank cover 2 is identical with the length of department of assembly 3., after realization assembles, end of the present invention is smooth.
The side of shank cover 2 is provided with the screwed hole corresponding with mounting groove 31 22, screwed hole 22 comprises first screwed hole 221 corresponding with the first mounting groove 311 and second screwed hole 222 corresponding with the second mounting groove 312, in the first screwed hole 221 and the second screwed hole 222, be equipped with holding screw 4, the end of this holding screw 4 with sew with long stitches embroider pin 5 offset.Compress sewing with long stitches in mounting groove 31 by holding screw 4 and embroider pin 5, the accuracy of embroidering pin 5 positions is sew with long stitches in guarantee, also ensured that the embroidery pin 5 sew with long stitches in two mounting grooves 31 parallels simultaneously, thereby make corresponding embroidering machine in use, the error of crosspointer cooperating is little, makes the quality of institute's converted products higher.
The first screwed hole 221 and the second screwed hole 222, taking the central point of its side, place as symmetrical centre, are symmetrically set on the side of shank cover 2.Thereby make the structure of whole shank cover 2 compacter, physical property is more superior.The moulding material of shank cover 2 is No. 45 steel, and its top layer is chromium coating, therefore its appearance is smooth, attractive in appearance and have good rust-proof effect, shank cover 2 of the present invention has advantages of specious and practical.
The present invention in use, by being inserted in the mounting groove 31 of department of assembly 3 sewing with long stitches embroidery pin 5, and tighten shank and overlap the holding screw 4 on 2, can realize by two sew with long stitches embroider pin 5 be fixed on front end of the present invention, again shank handle 1 is fixed on the head of crosspointer embroidering machine, therefore the present invention uses succinct, convenience very.
The present invention can also use as single needle shank, and in use, can only in a mounting groove 31, assemble and sew with long stitches embroidery pin, another mounting groove 31 emptying, now it can be fixed on common single needle embroidering machine head, is used as single needle shank and uses.On the other hand, the length of two mounting grooves is uncertain value, and it can be according to the need of work of embroidering machine, design become adapt length.
More than show and described general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain that the present invention requires is defined by appending claims and equivalent thereof.
