The invention relates to a laminated straight iron core of motor. Wherein, several tooth parts (11) of iron core (1) via the iron core bend part (12) of V-shape cut (13) are connected in band shape; at the direction that closes the V-shape cut (13), the bend part (12) is bended into annular shape; the front part of V-shape cut (13) has hole parts (14); protrusion is arranged opposite to the cut part (13); the part from the hole parts (14) to two sides of front of cut part (13) is parallel cut off, to form stress-proof parts (16, 16'), to improve the service life of punch mould and reduce the stress when bending iron core, to improve the process accuracy.

The invention relates to a non-pressure coin turn-over device, and belongs to the technical field of coin making equipment. The non-pressure coin turn-over device comprises a first-level conveying belt and a second-level conveying belt which are arranged in an up-down mode and have different motion directions. The output end of the first-level conveying belt is connected with the input end of the second-level conveying belt through a C-shaped turn-over coin guide plate. A gap is formed between the upper end of the C-shaped turn-over coin guide plate and the peak of the first-level conveying belt, and the width of the gap is larger than the thickness of a coin. The lower end of the C-shaped turn-over coin guide plate extends for connection along the conveying direction of the second-level conveying belt. By the non-pressure coin turn-over device, turn-over conveying of coins can be completed without any pressure, stability and reliability are guaranteed, and abrasion and damage to surfaces of the coins are completely avoided.

The invention discloses a building anti-seismic support and hanger hinge part. The building anti-seismic support and hanger hinge part comprises a cross beam, supporting columns are fixedly connectedto positions, close to the end faces, of the top of the cross beam, an arch-shaped reinforcing rib is fixedly connected between the two corresponding sides of the surfaces of the supporting columns, reinforcing devices are rotationally connected to the two ends of the cross beam, and locking devices are fixedly connected to surface sides of the reinforcing devices; balls are in rolling connectionwith the tops of the pipeline supporting blocks and located on the arc concave faces, pipeline fixing buckles are connected with the tops of the pipeline supporting blocks and located on the pipelinesupporting blocks in a matched mode, the lower ends of the pipeline fixing buckles are fixedly connected with the bottom of the cross beam through nuts, and protective pads are fixedly connected withthe tops of the inner walls of the pipeline fixing buckles. The invention relates to the technical field of anti-seismic equipment. The building anti-seismic support and hanger hinge part achieves theeffects of firmness, stability and pipeline protection, is firm in fixation, good in stability, high in supporting strength, safe and reliable, the abrasion damage is avoided, the service life is prolonged, and the use performance is improved.

The invention provides a cable protection and guide device, which can restrain wear of cables relative to two end edges of lengthwise direction of flexional inner circumferential side plate, prevent the generation of wear powder and the damage of cables, and simplify the disassembly work of partitioning wall plate to lighten the load of decomposing assembling work. The cable protection and guide device (100) consists of a pair of left and right link plates (120, 120), a flexional inner circumferential side plate (130), a flexional outer circumferential side plate (140) and a partitioning wallplate (150). The flexional inner circumferential side plate includes an abutting flap (131), an inner circumferential side flap (132) and an inner locking groove (133) which is formed in a stepped manner over the width direction and locks the hook locking base end portion (151) of partitioning wall plate. The flexional outer circumferential side plate includes an outer locking groove (141) which extends in width direction of the cable accommodating space (R) and locks a locking front end portion (152) of the partitioning wall plate.

A quick-linked belt includes a belt element, at least two reinforcing elements, at least two fixing elements and at least two connecting elements. The belt element includes a plurality of belt teeth and two binding portions. Each binding portion includes at least one penetrating hole, and each reinforcing element respectively penetrates through the penetrating hole, and each reinforcing element has a through hole. The two fixing elements respectively penetrate through the two through holes, and each connecting element includes at least two through holes and respectively supply each fixing element for pivoted positioning. The two binding portions seal the belt element in a ring through the connecting elements. The binding portion further includes a first recessed part and a second recessedpart, wherein the first recessed part of the binding portion is opposite to the second recessed part of the other binding portion, forming a recessed groove to accommodate the connecting elements. Theconnecting elements can be prevented from protruding during transmission, and interference can be prevented, and the strength of the quick-linked belt can be increased.

The invention discloses a packaging method of fresh cut flowers of anthurium and materials used for the packaging method. The packaging method comprises the following steps of: performing a grading process step on the harvested fresh cut flowers of the anthurium according to different grade standards, simultaneously washing clean, re-cutting a scape of each cut flower after the completion of grading, then sheathing into fresh-keeping pipes with fresh-keeping agents, placing the anthurium with the same grade into fixed paperboards with the corresponding specifications, placing ten flowers of the anthurium in each paperboard, then binding all the scapes, sheathing the paperboards into needle hole protection films, placing the paperboards into inner packaging boxes for fixing, placing two paperboards in each inner packaging box, placing the inner packaging boxes into an outer packaging box and placing 14 inner packaging boxes into each outer packaging box. The packaging materials comprise the outer packaging boxes, the inner packaging boxes, the fixed paperboards, the needle hole protection films and the fresh-keeping pipes. The packaging method disclosed by the invention is simple to operate, low in technical requirements on operation staff and high in packaging efficiency. The packaging materials have the advantages of simple and practical structure, low cost, aesthetic and elegant appearance and good protectiveness, and are suitable for various types of production enterprises of the fresh cut flowers.
