Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the present invention provides a hinge with positioning function, which comprises a first connecting body 2, a second connecting body 5 and a positioning block 3; the first connecting body 2 is provided with a connecting hole, and the second connecting body 5 is provided with an end head capable of extending into the connecting hole; pin holes are formed in the wall of the connecting hole and the end head; the positioning block 3 is sleeved outside the first connecting body 2. The outer side of the first connecting body 2 is provided with a positioning step, the positioning block 3 is sleeved on the positioning step, the positioning step is further provided with a spring retainer ring 4 for stopping, and the positioning block 3 can be effectively prevented from being loosened due to movement through the positioning block 3 and the spring retainer ring 4. The diameter of the positioning step on the first connecting body 2 is smaller than the maximum diameter of the first connecting body 2. Therefore, the positioning block 3 does not occupy the space of other parts of the first connecting body 2 or the second connecting body 5, and the rotation of the hinge does not influence the movement of the positioning block 3 in the guide tube 1. The appearance shape of the positioning block 3 in the moving direction is at least partially a curved surface, so that the contact area between the positioning block 3 and the guide pipe can be effectively reduced, and the sliding friction resistance of the positioning block 3 is reduced; if the curved surface is cut off from the complete curved surface part to form the plane 7, the contact area can be further reduced, and the gap between the positioning block 3 and the guide tube 1 can be increased.
As shown in fig. 2, in the present embodiment, the outer shape of the positioning block 3 is a shape in which a complete curved surface is partially cut into a plane. The number of planes 7 is two or more, and 3 are shown in fig. 2. In this way, the friction of the positioning block 3 moving in the duct can be further reduced.
In this embodiment, the positioning block 3 covers the area where the pin hole is located on the first connecting body 2; therefore, the corresponding portion of the positioning block 3 is provided with a groove for facilitating the insertion of the pin shaft 6 into the pin hole. After the pin shaft 6 is assembled, the positioning block 3 is rotated by a certain angle, and the pin shaft 6 is prevented from loosening and falling off by staggering the groove and the axis direction of the pin shaft 6. The matching part of the end head and the connecting hole is spherical, and the size of the part of the second connecting body 5 connected with the end head is smaller than that of the connecting hole, so that the second connecting body 5 can rotate relative to the first connecting body 2. Thus, the angle at which the first connecting body 2 and the second connecting body 5 can rotate relative to each other can be adjusted by the diameter of the inner hole (i.e., the connecting hole) at the end of the first connecting body 2.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to encompass such modifications and variations.
