This casting umbrella simple structure, processing is convenient, save time, and the canopy comprises a plurality of cloth scroll, and full umbrella does not have the strengthening band, need not to splice, and umbrella rope quantity reduces than ordinary casting umbrella, and work load such as tailor, sewing, assembly significantly reduces to above result to material utilization is high, so, the utility model discloses a casting umbrella low in manufacturing cost.

The delivery umbrella has high stability, does not swing in the descending process, and is favorable for the safety of air-dropped materials or equipment.

The purpose of the utility model can be achieved by adopting the following technical scheme:

the utility model provides a low-cost parachute, which comprises a parachute rope component and a canopy component. Each umbrella rope of the umbrella rope assembly is sequentially connected with a first group of cloth spokes and a second group of cloth spokes through a rope fastener, every two cloth spokes of the first group of cloth spokes and the second group of cloth spokes are separated by a certain distance to form a gap, the first group of cloth spokes and the second group of cloth spokes are mutually perpendicular and staggered to form a cross structure, and the second group of cloth spokes and the first group of cloth spokes are vertically staggered and overlapped by sewing.

Preferably, the second group of cloth webs and the first group of cloth webs have the same structural size and material.

Preferably, the number of the first group of cloth webs and the second group of cloth webs is more than or equal to three.

Preferably, the first group of cloth webs and the second group of cloth webs are vertically overlapped with each other at the central position of the first group of cloth webs and the second group of cloth webs in a cross shape.

Preferably, one end of the umbrella rope assembly is sewn into an umbrella rope loop by using a sleeve belt, and the other end of the umbrella rope assembly is connected with the umbrella coat assembly.

Preferably, the end parts of the first group of cloth banners and the second group of cloth banners form trepanning by folding and sewing, and all the umbrella ropes in the umbrella rope assembly sequentially penetrate through the end trepanning of all the cloth banners and are fixed with the self lap joint.

Preferably, the first group of cloth webs and the second group of cloth webs are made of any one of nylon, polypropylene, ultra-high molecular weight polyethylene and aramid fiber.

The utility model has the advantages of:

the utility model provides a pair of low-cost parachute, this delivery umbrella is the delivery umbrella of the cross structural style of making by the cloth scroll seam of two groups at a certain distance apart, reduces the parachute-opening dynamic load through the structure air permeability volume that increases the umbrella to improve the stability of umbrella, avoided ordinary delivery umbrella to move the complicated measure of carrying and taking for reducing the parachute-opening.

This casting umbrella simple structure, processing is convenient, save time, and the canopy comprises a plurality of cloth scroll, and full umbrella does not have the strengthening band, need not to splice, and umbrella rope quantity reduces than ordinary casting umbrella, and work load such as tailor, sewing, assembly significantly reduces to above result to material utilization is high, so, the utility model discloses a casting umbrella low in manufacturing cost practices thrift 40% ~ 60% than like product.
