Detailed Description

The technical solution of the present invention is further described below by way of examples and with reference to the accompanying drawings.

The embodiment is as follows:

the present embodiment is a simple single yarn strength testing device, as shown in fig. 1 to fig. 2: including casing 2, fixed station 4, sliding stand 5, actuating mechanism, powerful detection mechanism of fracture and elongation at break detection mechanism, 2 inside cavities that are equipped with of casing are equipped with spout 7 on the casing, and actuating mechanism includes motor and screw rod, and the casing top is located to motor 1, and the screw rod setting just exposes in the spout in the cavity. The fixed platform 4 is fixedly arranged on the upper part of the side face of the shell, the sliding platform is arranged on the lower part of the side face of the shell in a sliding mode and is arranged on the screw rod, and when the motor drives the screw rod to rotate, the sliding platform moves up and down on the screw rod. The breaking strength detection mechanism is arranged on the fixed table, and the breaking elongation detection mechanism is arranged on the fixed table and the sliding table.

As shown in fig. 3, the fixing table includes a first plate 41 and a second plate 42, the first plate 41 connects the second plate 42 and the housing, a groove is disposed on an upper end surface of the second plate 42, a through hole 44 is disposed on a bottom surface of the groove, the through hole penetrates through the second plate, and a first yarn clamp 3 and a breaking strength detecting mechanism are disposed in the groove. In this embodiment, the breaking strength detecting mechanism is a pressure sensor, and the pressure sensor is annularly disposed on the bottom surface of the groove body.

The sliding table 5 comprises a third plate body and a second yarn clamp 6, the third plate body is arranged on the screw rod, a rod body through hole is formed in the third plate body, and the second yarn clamp 6 is fixedly arranged on the third plate body.

The elongation at break detection mechanism includes that the surface winding has body of rod 8 and the brush of resistance wire, and the fixed setting of body of rod 8 upper end is terminal surface and the body of rod is in the body of rod through-hole under the first plate body, and the brush setting just offsets with the resistance wire on body of rod surface in the body of rod through-hole.
