The present invention provides a multi-pole connector capable of corresponding to multi-polarization of the interface, realizing space-saving of the interface part, and also capable of arranging a plurality of conducting body connection parts in the vertical direction on a mounting substrate. Multi-layer configuration correspondence. Equipped with a plurality of divided connectors (7, 8) that respectively hold conductors (2, 3) on each of the divided housings (5, 6) in the shape of dividing the housing (4) into a plurality of parts. The joint end surface of one of the split casings (5, 6) adjacent to each other is formed with a key fitting part (16) for the connection key (15) to be embedded. (16) Embedding the connecting key (15), so that the connecting key (15) is sandwiched between the joint end faces across the joint end faces to join the two split shells (5, 6), thereby connecting adjacent Each split connector (7, 8).

The invention discloses one-step forming process and die of a carbon fiber driving shaft. An inner die is in a disk type structure, is partitioned and cut along a center line, is buckled in a flange type and is connected by a bolt. The inner end of an outer die is in a disk structure; the outside of the outer die is in a sleeve structure; and the outer die is portioned and cut along a center line, is buckled in a flange type and is connected by a bolt. The sleeve part of the outer die is transversely cut along a partition surface on one side to form a compressed clamping strip so as to be convenient for fastening a mandrel. Fastening lug seats are correspondingly arranged on the inner die disk and the outer die disk and are provided with bolt holes. The one-step forming process comprises the steps of preparation of the carbon fiber driving shaft, flange preparation and ring flange shaping. In the invention, the ring flange processing die has simple structure, is simple, convenient and feasible for production process and is convenient and quick for processing and using; the one-step forming of the carbon fiber driving shaft and the flange can be realized and the production cost of the die and products can be reduced; the produced carbon fiber driving shaft has high concentricity; the continue track of secondary forming can be eliminated; the torsion strength of the flange of the carbon fiber driving shaft can be enhanced; and the production efficiency and the quality of products can be improved.

The invention relates to the technical field of twining of yarn, and discloses a device for improving the softness and strength of the yarn. The device comprises a shell, a yarn tensioning pillar is movably connected to the interior of the shell, a ventilation pipeline is hinged to the surface of the yarn tensioning pillar, and yarn winding pillars are movably connected to the two sides of the ventilation pipeline; air blowing ports are movably connected to the interiors of the yarn winding pillars, cooling pipelines are fixedly connected to the two sides of each air blowing port, a yarn outlet nozzle is movably connected to the side, away from the ventilation pipeline, of each yarn winding pillar, and a yarn guiding port is fixedly connected to the interior of each yarn outlet nozzle. Theyarn tensioning pillar is also driven to rotate, and conducts primary twisting on the yarn entering the yarn tensioning pillar from the right side, and then the yarn temporarily winds the yarn tensioning pillar, and afterwards, breaks away from the yarn tensioning pillar and winds the yarn winding pillars to be subjected to secondary twisting; the yarn winding the yarn winding pillars finally flows out of the yarn guiding ports in the yarn outlet nozzles, and then the yarn outlet nozzles are driven by rotation balls to rotate for third-time twisting. By means of the device, the effect of improving the twisting strength is achieved.

The invention relates to a transmission mechanism, in particular to a two-way main shaft transmission mechanism for an embroidery machine. The two-way main shaft transmission mechanism is used for the embroidery machine, and comprises a crossbeam, wherein a left-side transmission mechanism is arranged at the left side end of the crossbeam, and a right-side transmission mechanism is arranged at the right side end of the crossbeam; the left-side transmission mechanism drives the right-side transmission mechanism. The two-way main shaft transmission mechanism for the embroidery machine is simple and compact in structure and high in synchronism, and the warping strength is improved.

The invention relates to a non-woven air filter element air inlet pipe winding machine and a winding process thereof. The winding machine comprises an electric control box, a winding and rotating device, a feeding and walking device and a glue applicator that are all arranged on a frame; the feeding and walking device is connected with a non-woven roll and a nylon yarn roll; the electric control box is used for controlling the winding and rotating device to rotate; the electric control box is used for controlling the feeding and walking device to walk along the direction of the winding and rotating device and convey non-woven long strips and nylon yarns to the winding and rotating device to rotate and wind the non-woven long strips and the nylon yarns from inside to outside; and the glue applicator is used for applying glue to the non-woven long strips that are wound on the winding and rotating device synchronously. According to the winding machine disclosed by the invention, the non-woven long strips and the hard nylon yarns are adopted to be wound on a core rod uniformly, separately and obliquely, and are formed by bonding through applying glue; and the winding machine has the advantages of simple and compact structure, convenience for operation, simple process, short forming period, capability of satisfying a certain rigidity requirement that butting joint of an automobile engine and an air filter requires random bending under different assembling work conditions, long service life, recycling availability and no waste pollution.

The present invention relates to an eight-ball non-undercut type fixed constant velocity universal joint capable of improving torque capacity at high operating angles while ensuring durability at low operating angles. In this eight-ball non-undercut type fixed constant velocity universal joint, the center of the track groove (32) of the outer joint member and the center of the track groove (32) of the inner joint member are separated from the joint center plane (P) respectively. They are separated on both sides in the axial direction, and are biased at positions separated from the center axis (X) of the joint to the opposite side in the radial direction with respect to these track grooves (32). The distance between the center of the track groove (32) of the outer joint part and the center of the ball (37) is Rt, and the axial distance between the center of the track groove (32) of the outer joint part and the center plane (P) of the joint When it is F, the ratio R1 of F to Rt is 0.061R1≤0.087, and when the distance between the center of the track groove (32) of the outer joint member and the central axis (X) of the joint, that is, the offset in the radial direction is fr, The ratio R3 of fr to Rt is 0.07≤R3≤0.19.
