The utility model adopts less parts, improves the universality and has simple assembly form to realize the fixing function of the rotating shaft.
Description
Technical Field
The utility model relates to the technical field of automobile parts, in particular to a mechanical device with an active air inlet grille for fixing a vehicle or a rotating shaft.
Background
Under the prior art, the fixed two kinds of implementation methods that generally have of car initiative air intake grille flabellum pivot: one is to fix the rotating shaft by screwing the bracket and the body, and the other is to design the rotating shaft fixing structure of the body. For automobiles, the realization of functions can be ensured, and the principles of reliability, durability, cost and optimal weight are also ensured. The same is a rotating shaft fixing mode, so that the complex assembly process is reduced, the generalization degree is improved, and the weight cost is reduced, which is a development trend.
As shown in fig. 1, in the prior art, the upper end of the rotating shaft fixing support 3 adopts the self-tapping screw 2 to be screwed with the active air inlet grille body 1, and the lower end adopts the bolt limiting structure 5 to prevent the fan blade rotating shaft 4 from shaking in the rotating process, and the structure has the following problems:
1. the traditional active air inlet grille fan blade rotating shaft fixing support 3 is connected with an active air inlet grille body 1 through a self-tapping screw 2, and the structural design occupies a large space;
2. the assembly process is increased, and the weight and the cost are increased;
3. the rotating shaft fixing supports 3 at different positions cannot be used universally.
SUMMERY OF THE UTILITY MODEL
In order to solve the above technical problems in the prior art, an object of the present invention is to provide a latch-type shaft fixing structure.
The bolt type rotating shaft fixing structure comprises an active air inlet grille body and a rotating shaft fixing support, wherein the active air inlet grille body is provided with a mounting hole, a guide rail is arranged in the active air inlet grille body, and the guide rail is arranged opposite to a fan blade rotating shaft; the pivot fixed bolster includes link and grafting cylinder, and be provided with the joint groove on the link, the pivot fixed bolster inserts in the guide rail and the joint groove on the link with the pore wall joint of mounting hole is fixed, and the grafting cylinder of pivot fixed bolster with flabellum pivot cooperation is spacing.
Wherein, the guide rail is composed of a plurality of guide rail grooves.
Wherein, there is interval between the adjacent guide rail grooves.
Wherein the guide rails are vertically arranged inside the active grille shutter body.
Wherein, the connecting end and the inserting column body are of an integrated structure.
Compared with the prior art, the bolt type rotating shaft fixing structure has the following beneficial effects:
1. a self-tapping nail fastening structure is cancelled, so that the occupied space of the structure is saved;
2. the bolt type rotating shaft fixing support can be tightly pressed by hands, so that the assembly procedures are reduced, and the weight is reduced;
3. the bolt type rotating shaft fixing support can be universal at different positions, and cost reduction is facilitated.

Fig. 3 is a schematic view of an assembly manner of the latch type rotating shaft fixing structure of embodiment 1.
Fig. 4 is an assembled structural schematic view of the latch type rotating shaft fixing structure of embodiment 1.
Detailed Description
The latch type shaft fixing structure of the present invention will be further described with reference to specific embodiments to help those skilled in the art to more fully, accurately and deeply understand the technical solution of the present invention.
Example 1
As shown in fig. 2, the latch-type shaft fixing structure of the present embodiment includes an active grille shutter body 10 and a shaft fixing bracket 30, wherein the active grille shutter body 10 is provided with a mounting hole, a vertically arranged guide rail 40 is provided inside the active grille shutter body 10, and the guide rail 40 is disposed opposite to a fan blade shaft 50. The pivot fixed bolster 30 includes integrated into one piece's link and grafting cylinder, and be provided with the joint groove on the link, pivot fixed bolster 30 inserts in the guide rail 40 and the joint groove on the link with the pore wall joint of mounting hole is fixed, and pivot fixed bolster 30 the grafting cylinder with 50 cooperation of flabellum pivot are spacing. The guide rail 40 is formed of a plurality of rail grooves with a space between adjacent rail grooves.
Fig. 3 shows the installation direction of the rotating shaft fixing bracket, as indicated by arrows in the figure, and fig. 4 shows a schematic structure after assembly. The embodiment adopts less parts, improves the universality and realizes the fixing function of the rotating shaft in a simple assembly form. The bolt type rotating shaft fixing device can not be used for changing the bolt type rotating shaft fixing support screwing mode into the bolt type rotating shaft fixing support screwing mode, the upper end of the rotating shaft fixing support is connected with the active air inlet grille body in a clamping mode through a self-clamping structure, the rotating shaft fixing support is integrally inserted into the guide rail, and the rotating shaft of the fan blade is prevented from shaking in the rotating process.
It is obvious to those skilled in the art that the present invention is not limited to the above embodiments, and various insubstantial modifications of the method concept and technical solutions of the present invention are within the scope of the present invention.
