Background technique
In many regions, in order to cover to the sunlight in region, sunshade would generally be arranged in people.But traditional technology
In the usual size of sunshade be not adjustable, people will cause the waste of use space when few, people is more, and sunshade area is again inadequate, make
With extremely inconvenience.There are also sunshade use stretching structure, one end is fixed, and the other end be free end and can be unfolded with
It is flexible.
But existing sunshade is mostly to realize to fold and unfold operation, bracket by movable support among tarpaulin
Have plenty of in mechanism and folding plastic plate is used using the prominent strut skeleton of arc, some, some uses folded metal bar or gold
Belong to hardened structure, the structure or structure of folded portion and deploying portion are too simple, and stability is poor, be easy to happen fracture or
The phenomenon that deformation, causes related elements to be scrapped in advance；Excessively complicated, cost is high, from great, working service cost is big, and
Equally exist the jiggly problem of operation.
Utility model content
The technical issues of the utility model is solved be to provide a kind of sunshade stretching structure, and structure is simple, from heavy and light,
Flexibly, service performance is stablized for movement, can be used to solve the defects of above-mentioned background technique.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of sunshade stretching structure, including several dismountable telescopic joints, the expansion joint structure is consistent, is symmetrically installed
It include support frame and symmetrically arranged brace on the support frame in tarpaulin two sides, the brace includes straight arm section and convex
Seat, the straight arm section base portion are hinged on support frame, torsional spring are embedded in the hinge, the torsional spring is in non-stress shape
It is contraction state that brace is controlled under state, and a torque amplification device and a band manual releasing switch are further sleeved on torsional spring
Torsional spring check device；And the other end opposite with hinged end is free end, and the projection seat is molded over free end end face, it is described
Form a cross through hole in projection seat, and be set with a tarpaulin fixing buckle in this cross through hole position, and position it is adjacent two
A brace is hinged in cross through hole position.
It in the present invention, is detachable mounting structure between the tarpaulin fixing buckle and projection seat.
In the present invention, the tarpaulin fixing buckle is figure-8 structure, and intermediate portion is sleeved on the transverse direction of projection seat
In through-hole.
In the present invention, tarpaulin passes through the tarpaulin fixing buckle and support of two brace free ends in sunshade unilateral side
Frame realizes that bikini is fixed.
It in the present invention, further include a rigid support, the entirety of the rigid support on sunshade stretching structure
For expansion joint structure, and a sliding slot is formed on the inside of rigid support, and support frame as described above is provided with one in hinge position
Protruding portion, which is embedded in sliding slot, and can be slid along the chute.
The utility model has the advantages that the utility model structure is simple, from heavy and light, it conveniently can freely realize and unfold and fold gathering,
Effectively tarpaulin can be supported by the setting of brace structure, and relative to its stability of traditional truss-like tarpaulin support construction
More preferable with anti-deformation nature, the setting of cooperation tarpaulin fixing buckle can effectively prevent tarpaulin and Folding Deformation occur on the support structure,
Its is aesthetic in appearance, and paulin is conveniently replaceable, and service performance is stablized.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Fig. 2 is the schematic cross-section of the A-A of Fig. 1 support arm section.
Wherein: 1, rigid support；2, brace；3, sliding slot；4, support frame；5, tarpaulin fixing buckle；6, torsional spring；7, concentric shafts
Set；8, tarpaulin fixing buckle.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to the preferred embodiment of a kind of sunshade stretching structure of Fig. 1, Fig. 2, in the present embodiment, including it is symmetrical arranged
It stretches the telescopic component of side two sides in tarpaulin, the telescopic component includes the rigid support 1 with stretching structure and several flexible
It saves, is provided with sliding slot 3 on the medial surface of rigid support 1, and telescopic joint includes support frame 4 and symmetrically arranged on the support frame
Brace 2, this brace 2 is mounted on support frame 4 in base portion by being cut with scissors by hinge, and support frame 4 is provided with one in hinge position
Protruding portion, which is embedded in sliding slot 3, and 3 can be slid along the chute；And be provided on 2 free end of brace one it is convex
Seat, setting forms a cross through hole in this projection seat, and is set with a tarpaulin fixing buckle 5 in this cross through hole position, and position
Set that two adjacent braces 2 are hinged in cross through hole position, the structure of hinged place is as shown in Fig. 2, two adjacent braces 2 are logical
It crosses and is formed together in cross through hole position by concentric axle sleeve 7 suit, and be equipped with one in the hollow hole site of concentric axle sleeve 7
