Technical field
The present invention relates to the mounting technique between a kind of automobile and article shading curtain, more particularly, to field of automobile parts and components, one
It is kind simple and practical in structure, can play the role of when necessary buffering, disengaging a kind of automobile sun blind frame and mounting hole safe escape
Device.
Background technique
With the development of society, private car is more and more, the space of vehicle is also increasing, especially after SUV vehicle
Row is generally equipped with an article shading curtain on rear side of seat, is placed in the boot of automobile when not used, and the used time to utilize article shading curtain two
The telescopic mounting head at end is mounted in the mounting hole of vehicle two sides, and stretching, extension cord is clasped in the rear end of automobile, can be covered
The object of boot, and lighter object can be placed on cord, it is beautiful and practical.There are all kinds of numerous article shading curtains in the market,
It but is all the structure and practicability for removing to improve article shading curtain itself with different technologies.And the curtain frame of article shading curtain is more elongated pipe
Shape is easy to lose when being adjusted excessive extruding by back seat.
Application No. is 201821518188 to disclose a kind of sliding-type automobile article shading curtain, including outer tube, is connected on outer tube
The big door curtain made of cloth, the big door curtain made of cloth are connected with the side door curtain made of cloth, and locating rod is provided between the big door curtain made of cloth and the side door curtain made of cloth, connects two small cloth on outer tube
Curtain, the small door curtain made of cloth one and the small door curtain made of cloth two, the connection type between two small door curtains made of cloth and outer tube are to be fixed on outer tube there are two card slot,
