When the transmission device is not locked, as the transmission device is pulled by the flexible constraint rope and cannot enter a transmission channel, thereby further avoiding failure occurrence.

The invention relates to the field of pneumatic pipeline transmission. A novel conveyor comprises a barrel body and a cover body, wherein a locking mechanism and a locking detection mechanism used for detecting whether the locking mechanism locks or not are arranged on the barrel body or the cover body. Not only is a locking function ensured, interlocking can also be realized. The locking connection safety and reliability of the cover body and the barrel body of the conveyor are improved, conveying efficiency is improved, and privacy is improved.

The invention discloses a locking structure for a round plastic container. The locking structure for the round plastic container comprises a barrel body and a barrel cover, wherein a plurality of barrel cover thread strips are arranged on the inner side of the barrel cover; a rack is arranged on one surface, connected with the barrel body, of the barrel cover; a plurality of barrel body thread strips are arranged on the periphery of the outer side of the opening of the barrel body; the barrel cover thread strips and the barrel body thread strips are matched with each other; a set of gears are arranged on the edge of the upper opening of the barrel body; a fixed gear central shaft is arranged in the gears, and is the gears are connected with a gear handle; when the barrel body is motionless, the gear handle drives the gears to rotate anticlockwise, and then the rack on the barrel cover and the whole barrel cover are driven by the rotating function of the gears to move clockwise; with less power, the lever effect of the gear handle on the gears and the effect of thread inclined plane moving are adopted to produce tens times of locking force of the barrel body and the barrel cover, so that the barrel cover and the barrel body are locked; when the gear handle swings clockwise, and the barrel cover moves anticlockwise, the barrel cover is then loosened; the way of locking and unlocking the barrel cover and the barrel body is very convenient.

The invention relates to the field of large circular knitting double-sided knitting machines, in particular to the needle plate adjustment structure of the double-sided machine, which includes locking screws, a hollow screw cover set on the locking screw, and a hollow screw cover set under the hollow screw cover and set on the locking screw. The locking block of the screw, the locking screw passes through the support plate and is locked on the upper dial, the hollow screw sleeve is arranged in the through hole of the support plate, and the hollow screw sleeve is threadedly connected with the through hole of the support plate, so The bottom of the hollow screw jacket is provided with a "ten"-shaped groove, and the upper end of the locking block is provided with a "ten"-shaped convex key to match the "ten"-shaped groove. The "ten"-shaped convex key is inserted into the In the "ten"-shaped groove, due to the above-mentioned structure, this structure ensures the locking function of the locking screw, and makes it easy to adjust the flatness of the dial, ensuring the rigidity of the whole machine. All locking screws only Under simple tension, all locking blocks and threaded sleeves are tightly combined, while the upper dial is tightly connected to the support plate, and there will be no wave-like stress deformation, and the installation strength of the whole machine is higher.

The invention discloses an improved locking device for a main rotating shaft. The device is characterized in that a torsional spring which can overcome screwing frictional resistance between the main rotating shaft and a connecting nut is additionally arranged between the connecting nut and the main rotating shaft so as to prevent the main rotating shaft from uncontrollable high-speed rotating caused by human errors; the connecting nut can overcome the thread frictional force relative to the main rotating shaft under the effect of the inverted torsion of the torsional spring, and thus the connecting nut can be rotated relative to the main rotating shaft, and as a result, the main rotating shaft can be braked. The invention also provides another scheme for locking the main rotating shaft. The scheme is characterized in that an inner pawl which can be limited through an elastic connector is arranged on a flywheel disc; in case that the main rotating shaft is subjected to uncontrollable high-speed rotating, the outward centrifugal force of the inner pawl on the flywheel disc can be utilized to overcome the tensioning force of the elastic connector, thus the inner pawl can be locked to an inner ratchet wheel, and as a result, the function of locking the main rotating shaft can be further achieved.

The locking member (80) has an end (65) which is in the arrangement direction of the terminal of the housing (60), a base of the configuration face (65E) configured on the side opposite the object connector, and a locking part (82) extending from the base. The locking part forms an abutting part which is abutted against the locking part (35A) of the objection connector for clamping from the range which is spaced from the end rim (65E-1), and a clamping stop concession part (82B) for clamping the locking part is formed in the spaced range, In the embedding state of the electric connector, the abutting part of the part to be locked oppose the base (35A-1) of the locking part, and the front ends of the clamping concession part of the locking part oppose to the front end of the locking part.

The invention relates to an omnidirectional multi-functional disk type elongating mill, the diameters of an upper and a lower guide disk are increased; the lifting of the upper guide disk adopts a turbine, a worm and a leading screw device; the lifting of the lower guide disk adopts a standard spiral elevator; and the axial direction adjustment is realized by the standard spiral elevator; the positive direction location, lateral direction location and upper and lower direction location are realized by a hydraulic cylinder. The axial direction adjustment of the roller is realized by the standard spiral elevator; the radial direction is adjusted by the combination of a non-standard spiral elevator and the hydraulic cylinder; the locking device adopts the hydraulic cylinder and an adjusting wedge mechanism. Guide bushes of an outlet and an inlet port adopt the upper-pressing and lower-locking of the hydraulic cylinder. The reliability is increased by adopting the hydraulic system; the enlarged diameters of guide disks can improve the locking condition of the roller, the elongation coefficient is increased, screw threads in the steel tube are reduced after rolling, and the variety of products is enlarged; gaps of the axial direction and radial direction of the guide disks and the roller are reduced, and the stability of the rolling is strengthened; the structure of the side pressure oil cylinder of the roller is simple, and the running is reliable; the guide bushes of the outlet and inlet port adopt the upper-pressing and lower-locking device to realize the double-assurance.
