Abstract

The utility model belongs to the tent umbrella technique, particularly a folding tent frame which can prevent a tent surface from generating downwards concave phenomenon and reduce abrasion. The utility model comprises a telescopic angle column, a fixed angle and a sliding angle which are arranged at the upper end of the angle column, and a cross link rod which is respectively connected with the fixed angle and the sliding angle through pins. The utility model is characterized in that the fixed angle and the sliding angle are also respectively connected with tent bones and a tent support through the pins, the tent bones are connected by a hinge, and the upper ends of the tent bones are connected with a top connecting piece through the pins. The utility model is especially suitable for people to carry during traveling or field operation.

Description

Collapsible hood frame

The utility model belongs to paulin umbrella technical field, particularly a kind of paulin frame of the collapsible shelter that is convenient for carrying.

In the existing cover from sun that is fit to carry, the mainstream product in the market is the parasol with big umbrella cover, and its shortcoming is that umbrella bar and umbrella shank have occupied more shed space, has influenced umbrella cover and has effectively utilized area.For overcoming this defective, many umbrella bars have appearred at four jiaos awning product, as Chinese patent 95218927.5 " open-shut type paulin frame ", its four jiaos is telescopic post, pushing up middle part, relative both sides grizzly bar at frame connects, push rod can insert in the middle of the grizzly bar, cover with tarpaulin after, constitute sharp ceiling surface by push rod and four edges.Because its top and all around between be not similar to the umbrella rib structure of umbrella, constitute the inclined-plane by the tension force of tarpaulin fully, be easy to generate the recessed and ponding of tarpaulin, and then produce and in the paulin dripping phenomenon is arranged, and tarpaulin has only the stress point in push rod top, very easily makes tarpaulin worn out.

The purpose of this utility model provides a kind of collapsible paulin frame that can prevent that tarpaulin is recessed and reduce to wear and tear.

The utility model comprises the bushing type corner post, the corner post top is fixed with decides the angle, reach with the corner post shaft and be the movable sliding angle that cooperates, cross one another with deciding the angle and sliding angle pin connecting rod even on every corner post, the crosspoint connects into the scissors shape with pivot pin, the corresponding in opposite directions termination of the connecting rod that is connected on each adjacent corner post connects with hinge or pivot pin respectively, it is characterized in that deciding the angle and the three-dimensional joint is respectively arranged with sliding angle, wherein two side connectors connect with scissors shape connecting-rod head pin respectively, transition joint connects with paulin bone and paulin support pin respectively, and the other end and the paulin bone pin of paulin support connect; Connected by hinge in the middle of the paulin bone, top and roof connecting pin connect.

The paulin frame can be made into shapes such as four jiaos, five jiaos, hexagonal, and its corresponding corner post has 4,5 or 6, and corresponding roof connecting has 4,5 or 6 joints that are connected with the paulin bone.

Paulin frame provided by the utility model owing to increased paulin support and folding paulin bone, makes the paulin face of coveing with well-pressed, is difficult for ponding, and tarpaulin is stressed by roof connecting and many newspaper paulin bone together support, has reduced the wearing and tearing of tarpaulin, increases the service life.

In the accompanying drawing, Fig. 1 is these practical four jiaos of paulin embodiment open configuration structure charts, Fig. 2 is Fig. 1 structure front view when being folded into pencil, Fig. 3 decides angle, sliding angle and corner post, paulin bone, paulin support, roof connecting connection layout, Fig. 4 is for deciding angular shape figure, Fig. 5 is Fig. 4 upward view, and Fig. 6 is sliding angular shape figure, and Fig. 7 is Fig. 6 vertical view.

Be described further below in conjunction with accompanying drawing.

Pipe 1 constituted Collapsible structure in corner post was placed in by outer tube 2, and pin 9 is positioned at outer tube 2 lower ends, can adjust the corner post height.Decide angle 4 for four and be separately fixed at each outer tube 2 top, its joint 4-1,4-3 respectively with its two to the scissors shape connecting rod that constitutes by pin 86 pins connect joint 4-2 and paulin cream 12 lower ends pin company; Four sliding angles 3 are inserted in each corner post respectively and also can be slided up and down, and will slide angle 3 by elasticity non-return card 15 when paulin opens and block; Joint 3-1, the 3-3 at sliding angle 3 respectively with two to connecting rod 5 pins connect, joint 3-2 and paulin support 10 pins are even; Paulin supports 10 upper ends and connects with connector 11 pins that are fixed on the paulin bone 12; Constitute folding structure by hinge 13 in the middle of the paulin bone 12, top and roof connecting 14 pins connect.

Button can be drawn by bonding nylon in outer tube 2 upper ends during installation, after tarpaulin is topped velcro on its angle is buckled by tightly with drawing, and promptly forms awn.If place curtain cloth again at four jiaos, also can work as the field and use the room temporarily, be particularly suitable for field work and use.

When the paulin frame draws in, only need respectively each non-return card 15 to be pressed into, extract each alignment pin 9 sliding angle 3 and outer tube 2 are glided, then by each hinge mechanism and pivot pin bindiny mechanism, quadrangular prism inwardly draws and forms pencil in, as shown in Figure 2.
