Detailed Description

As shown in fig. 1, an embodiment of the present invention discloses an automobile sun visor skeleton, including:

the mounting rings 1 are at least two and are used for being sleeved with the limiting rod;

the base 2 is fixedly connected with the sun shield main body;

the base 2 and the mounting ring 1 are integrally formed, the two areas are in smooth transition, and the surface of the transition part is not sunken.

Preferably, the limiting device further comprises a limiting pipe 3 which is arranged between the two mounting rings 1 and is arranged on the base 2 and matched with the limiting rod, and the cross section of a cavity of the limiting pipe 3 is an incomplete circle. Preferably, the cavity cross section of the limiting tube 3 is composed of a major arc and a straight line. The limiting pipe 3 in the shape is matched with a limiting rod matched with the limiting pipe, so that the limiting pipe 3 and the limiting rod have a mutual extrusion force when the framework rotates around the limiting rod, the sun shield can be stopped at any required position, and the sun shield and the limiting rod are opposite in position when being folded, and cannot be displaced when not manually rotated.

Preferably, the limiting pipe 3 is matched with the base 2 in a plugging manner. Because the function is different, spacing pipe 3 and base 2 optional different materials are makeed respectively, and the grafting cooperation simple to operate is swift, and because the follow-up can put into mould with its whole with sunshading board main part rigid coupling, also need not worry that the connection between the two is not inseparable enough.

Preferably, the two ends of the two side surfaces of the base 2 parallel to the mounting ring 1 are respectively provided with a positioning groove 4 for positioning the base in the mold. The positioning of the framework is convenient when the sun shield main body is manufactured.

The utility model provides a sun visor board mould, has the mould, the lower mould with be located the lifter 5 between mould and the lower mould, 5 tip of lifter with the cooperation of pegging graft of the collar 1 of car sun visor board skeleton, make the plane part of the spacing pipe 3 inner walls of a side laminating of 5 tip of lifter, its cambered surface part of the spacing pipe 3 inner walls of offside conflict, go up the mould with the lower mould is opened there is the groove of stepping down 6 that holds lifter 5. When the sun visor is used, the lifting rod 5 is lifted firstly, the framework is sleeved at the end part of the lifting rod 5, the lifting rod 5 is put down to place the framework in the lower die, then the upper die is put down to place the framework at the specified position in a cavity formed by enclosing the upper die and the lower die, and then the sun visor main body is manufactured. Wherein, the angle that the skeleton was put into has just been injectd in the laminating of 5 side of lifter and spacing pipe 3, and lifter 5 can only follow vertical direction and reciprocate, has also restricted the horizontal position that the skeleton was put into.

Preferably, the main body of the lifting rod 5 and the part inserted into the framework form a limiting step, so that when the framework is sleeved on the lifting rod 5 and abuts against the step, the position and the angle of the framework relative to the lifting rod 5 are fixed, and the horizontal position of the framework is further limited.
