1. Field of the Invention
The present invention relates to a positioning device for a rack, and more particularly to a positioning device for a rack on the rear of a vehicle thereof, which can carry bicycles and goods simultaneously.
2. Description of the Prior Art
A recreation vehicle or a jeep usually comprises a connecting base with a ball mounted the rear carriage or rear portion thereof, which is provided for towing a car away by cooperating with a towing pole, and carrying a bicycle by cooperating with a bike rack.
A conventional positioning device for a rack on the rear of a bicycle thereof as shown in
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a positioning device for a rack on the rear of a vehicle thereof, comprising a main body, two clipping blocks, a tightening assembly and a connecting tube. The main body including a positioning base that connected to a connecting base in the lower side of the positioning base thereof, the clipping blocks are mounted the lower side of the connecting base oppositely, the tightening assembly is provided for tightening the clipping blocks to be clipped the ball so as to rotated pivotally. The clipping blocks are clipped on a ball of the connecting base of the car, and the connecting tube is positioned to the positioning base of the main body for inserting a bike rack. The rack can be rotated to create a vertical or a horizontal structure according to the requirement for carrying the bicycle or luggage by cooperating with the shelf.
The further objective of the present invention is to provide a positioning device for a rack on the rear of a vehicle thereof, except the function of carrying the bicycle, the rack can be pivotally rotated to be creating a horizontal structure, thus providing for carrying goods by cooperating with the shelf, which is very practical.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiments in accordance with the present invention.

Sticking the pressing sections 741 of the side poles 74 to the outer side of the supporting poles 71, the ends of the connecting pole 72 and the mounting pole 73 are inserted into the mounting holes 711 of the supporting poles 71 by passing through the positioning holes 71 2 of the supporting poles 71 by the screws 75, and connected to the inner threaded hole 721 of the connecting pole 72, and the screws 76 are passed through the locking holes 7411 of the side pole 74 and the positioning holes 712 of the supporting poles 71, and connected to the inner threaded hole 721 of the connecting pole 72, similarly, the screws 77 are passed through the locking holes 7411 of the side pole 74, and connected to the inner threaded hole 721 of the connecting pole 72.
For the above-mentioned device, the advantages of the present invention describes as follows:
Firstly, except the function of carrying the bicycle, the bike rack 50 can be pivotally rotated to be creating a horizontal structure, thus providing for carrying goods by cooperating with the shelf 70, which is very practical.
Secondly, since the locking screws 33 of the tightening assembly 30 are passed through the locking holes 212 of the clipping blocks 20 and positioned to the locking grooves 213, the bike rack 50 can be positioned to the ball 61 of the connecting base 60 by cooperating with the thumb screw 32 of the tightening assembly 30, thereby the sleeve 22 of the clipping block 20 will be pressed against the edge of the arc-shaped concave portion 221 so as to solve the problem of loosing.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
