Still be provided with locating hole A on the preceding skeleton, locating hole B that locating hole A position corresponds during preceding base was provided with canopy body operating condition to and the locating hole C that locating hole A position corresponds during with canopy body fold condition extreme position, during canopy body operating condition, the spacer pin of packing into in locating hole A and the locating hole B is used for the fixed canopy body in order to keep operating condition, and the spacer pin of packing into in locating hole A and the locating hole C is used for the fixed canopy body in order to keep fold condition during canopy body fold condition extreme position.

Furthermore, the rotatable connection mode of the one end of preceding skeleton and preceding base, the preceding skeleton other end and canopy body front end, the one end of back skeleton and back base and the back skeleton other end and canopy body rear end is through different hinge pin connections.

Furthermore, there is a limit pad on the front base through the screw connection, and the limit pad is used for assisting the spacing to the front framework when the canopy body folds the extreme position.

The utility model has the advantages of it is following:

the utility model provides a pair of paver sunshade folding device and stop gear, the sunshade canopy body is connected with all articulating between sunshade skeleton, sunshade skeleton and the base, forms a similar "parallelogram" articulated connecting rod structure, and rear end installation hydraulic cylinder realizes the lift sunshade through the flexible of hydro-cylinder, and all has the spacing locking of spacer pin at the vertical operating condition of sunshade and folding transport state, and it is spacing to lock reliably accurate, avoids the potential safety hazard.

Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1, a folding stop gear of paver sunshade, including the paver, its characterized in that: it includes preceding base 1, preceding skeleton 2, the canopy body 3, back base 4, after-frame 5, hydro-cylinder 6 and spacer pin 8, preceding base 1 and after-frame 4 fixed connection in the frame of paver, the one end and the preceding base 1 rotatable coupling of preceding skeleton 2, the other end and the front end rotatable coupling of the canopy body 3, the one end and the after-frame 4 rotatable coupling of after-frame 5, the other end and the rear end rotatable coupling of the canopy body 3, the one end of hydro-cylinder 6 and the frame fixed connection of paver, the other end is articulated with after-frame 5.

Still be provided with locating hole A on the preceding skeleton 2, be provided with on the preceding base 1 with the canopy body 3 during operating condition locating hole A position corresponding locating hole B101 to and the locating hole C102 that locating hole A position corresponds during the folding condition extreme position of the canopy body 3, during the canopy body 3 operating condition, the spacer pin 8 of packing into in locating hole A and the locating hole B101 is used for fixed canopy body 3 in order to keep operating condition, and the spacer pin 8 of packing into in locating hole A and the locating hole C102 is used for fixed canopy body 3 in order to keep folding condition during the canopy body 3 folding condition extreme position.
