Abstract
The utility model discloses a yarn trapper and large screw rod connecting structure. The connecting structure comprises a large screw rod and a yarn trapper. The front portion of the large screw rod is sleeved with a yarn picking spring. A stair head with the reducing diameter is arranged at the front end of the large screw rod. A screw rod hole is formed on the yarn trapper. The stair head penetrates through the screw rod hole and is fixed by a nut. A gasket is arranged between the yarn trapper and the yarn picking spring. According to the connecting structure, the wave-shaped gasket is compressed so as to enable large friction force to occur between the large screw rod and the yarn trapper, so that the large screw rod is fixed; an elbow on the end portion of the yarn picking spring is wedged into a spring groove of the large screw rod and can slide in the axial direction in the spring groove, so that the elastic force of the yarn picking spring can be adjusted as long as the angle of the large screw rod is rotated clockwise or anticlockwise. Consequently, the elastic force of the yarn picking spring can be adjusted conveniently.
Description
Technical field
The utility model relates to tension disk and large screw connecting structure.
Background technology
As shown in Figure 1, in prior art, large screw rod 2 front end terminations are directly tightened on tension disk 1 and are made thread take-up spring 3 fixing simultaneously by screw thread.The frictional force that wherein elastic force of thread take-up spring 3 regulate to be to utilize large screw rod when tightening and thread take-up spring end face produces drives, and the shortcoming of this kind of structure is the bad control of the elastic force of thread take-up spring.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of tension disk and large screw connecting structure, the convenient elastic force of controlling thread take-up spring.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of tension disk and large screw connecting structure, comprise large screw rod and tension disk, described large screw rod front portion is socketed with thread take-up spring, described large screw front end is provided with the ladder head that diameter diminishes, described tension disk is provided with screw hole, and described ladder head passes screw hole and fixed by nut, between described tension disk and thread take-up spring, is provided with pad.
Preferably, described pad comprises two flat shims and is clamped in two corrugated gaskets between flat shim.
Preferably, described large screw rod outer circumference surface is provided with axially extended spring groove, and the termination of described thread take-up spring is provided with elbow, and described elbow slides and is arranged in described spring groove.
Thereby the utility model utilization makes large screw rod and tension disk produce the fixing large screw rod of larger frictional force after compressing corrugated gasket, and elbow on thread take-up spring termination is to be inserted in the spring groove of large screw rod, and can in spring groove, slide vertically, thereby the adjusting of thread take-up spring elastic force, only need along the large screw rod angle of reverse rotation, facilitated the elastic force of controlling thread take-up spring.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is tension disk and large screw connecting structure schematic diagram in prior art;
Fig. 2 is tension disk and large screw connecting structure schematic diagram after the utility model improves;
Fig. 3 is I place structure for amplifying schematic diagram in Fig. 2;
Fig. 4 is the elbow of thread take-up spring and the spring groove fit structure schematic diagram of large screw rod.
The specific embodiment
Below in conjunction with Fig. 2 to Fig. 4, tension disk of the present utility model is made and being illustrated with large screw connecting structure.It comprises large screw rod 2 and tension disk 1, described large screw rod 2 front portions are socketed with thread take-up spring 3, described large screw rod 2 front ends are provided with the ladder head 20 that diameter diminishes, described tension disk 1 is provided with screw hole, described ladder head 20 passes screw hole and is fixed by nut 10, and 3 of described tension disk 1 and thread take-up springs are provided with pad.Described pad comprises two flat shims 11 and is clamped in the corrugated gasket 12 of 11 of two flat shims.Described large screw rod 2 outer circumference surfaces are provided with axially extended spring groove 21, and the termination 30 of described thread take-up spring 3 is provided with elbow 31, and described elbow 31 slides and is arranged in described spring groove 21.
While regulating thread take-up spring 3 elastic force, along large screw rod 2 angles of reverse rotation, elbow 31 is in the interior slip of spring groove 21, and the compression degree of thread take-up spring 3 there will be variation, thereby realizes the control of thread take-up spring elastic force.
