The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

The embodiment of the utility model discloses a hinge base fixing structure, as shown in fig. 1-6, comprising: the rotating member is rotatably connected with the base 2, and locks the base 2 by rotational interference. In the specific implementation, the base 2 is mounted in the frame profile 1, and the rotating member is in rotational interference with the groove 11 of the frame profile 1.

It should be noted that, because the rotating member is rotationally connected with the base 2, the rotating member locks the base 2 through rotation interference, and then provides a hinge base fixing structure, the assembly efficiency is high, the locking operation is simple and convenient, and the production and time cost can be effectively saved.

As shown in fig. 1-3, the rotating member is an eccentric shaft 3.

As shown in fig. 1 to 3, the eccentric shaft 3 includes an eccentric body 31 and a first skirt 32, the base 2 is locked by rotational interference of the first skirt 32, and the first skirt 32 abuts against the inner side wall of the groove 11. In a specific implementation process, the eccentric body 31 and the first skirt edge 32 are integrally formed, and the end surface of the first skirt edge 32 is inclined.

As shown in fig. 4-6, the rotating member is a notched shaft 4.

As shown in fig. 4 to 6, the notch shaft 4 includes a notch body 41 and a second skirt 42, the base 2 is locked by rotational interference of the second skirt 42, and the second skirt 42 abuts against the inner side wall of the groove 11. In a specific implementation process, the edge-missing body 41 and the second skirt 42 are integrally formed, and the end surface of the second skirt 42 is inclined.

As shown in fig. 4-6, the base 2 is provided with at least one boss 21. In the specific implementation process, the number of the bosses 21 is two, and the bosses 21 are provided with chamfer angles in arc shape.

As shown in fig. 4 to 6, the boss 21 and the base 2 are integrally formed.

As shown in fig. 4 to 6, the base 2 is provided in an L-shape, and specifically, the base 2 includes a cross plate end and a riser end, and the frame profile 1 is provided in a T-shape.

When the eccentric shaft 3 or the edge-missing shaft 4 rotates anticlockwise, the upper part of the eccentric shaft 3 or the edge-missing shaft 4 interferes with the side wall of the notch of the frame section bar 1, the base 2 is extruded to deflect rightwards until the clearance between the eccentric shaft and the right side of the frame section bar 1 reaches the minimum, the base 2 is counteracted to give an upward lifting force to the base 2, so that the base is in a more stable installation state, meanwhile, the first skirt edge 32 or the second skirt edge 42 is clamped into the clearance between the notch of the frame section bar 1 and the base 2, an oblique upward pressure is given to the notch of the frame section bar 1, the friction force between the notch and the base is increased, the stability of the vertical plate end of the base 2 is enhanced, the fastening requirement of the base is met, and the base is simple and practical to operate.

Working principle: because rotating member and base 2 rotate to be connected, the rotating member is through rotatory interference to the locking of base 2, and then provides a hinge base fixed knot and constructs, and packaging efficiency is high, and locking is easy and simple to handle, can save production and time cost effectively.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments.
