icon: 1-a first bracket head, 101-a first positioning block, 2-an adapter, 201-a sink, 202-a second positioning groove and 3-a second bracket head.
Detailed Description
Referring to fig. 1, a composite bracket for fixing landing gear and test bed includes a first bracket head 1, an adapter and a second bracket head 3, in practical application, the adapter 2 of multiple specifications is designed according to each type of aircraft landing gear; the first bracket head 1 is connected with the test bed through a screw, the second bracket head 3 is connected with the landing gear assembly through a screw, and it is understood that a plurality of mounting holes for mounting the screw are formed in the first bracket head 1 and the second bracket head 3; in addition, the shapes of the first and second bracket heads 1 and 3 are not particularly limited as long as the mounting strength and size requirements can be satisfied.
Therefore, the existing integrated bracket is split into the adapter 2, the first bracket head 1 and the second bracket head 3, and the three parts are processed and then are installed to form the composite bracket, and only the adapter 2 with corresponding specification is needed to be replaced according to the landing gear of each model during test, namely, the composite bracket provided by the utility model only needs to process a plurality of sets of adapters 2, so that the consumption of raw materials is greatly reduced, and the processing deformation of each part is conveniently controlled by splitting the three parts, and the qualification rate is improved.
On the basis of the above, the two sides of the adapter 2 of this embodiment are provided with the sinking grooves 201, the two ends of the sinking grooves 201 are provided with connecting holes, the positions of the first bracket head 1 and the second bracket head 3 corresponding to the connecting holes are provided with threaded holes, and when the adapter is installed, screws penetrate into the first bracket head 1 and the second bracket head 3 from the sinking grooves 201 of the adapter to be connected. It is to be understood that in other embodiments of the present utility model, if the installation space is enough, screws may be inserted into the adapter 2 from the first bracket head 1 and the second bracket head 3 for connection (i.e. the first bracket head 1 and the second bracket head 3 are provided with connection holes, and the adapter 2 is provided with threaded holes at corresponding positions). It should be noted that, since the adapter 2 needs to be provided with multiple sets, the processing of the connecting holes on the multiple sets of adapter 2 is easier than the processing of the threaded holes, and the processing efficiency is improved.
Referring to fig. 2, one of the first bracket head 1 and the adapter 2 is provided with a first positioning block 101, and the other is provided with a first positioning groove which is matched with the first positioning block 101; one of the second bracket head 3 and the adapter 2 is provided with a second positioning block, and the other is provided with a second positioning groove 202 matched with the second positioning block.
Specifically, in this embodiment, the first positioning block 101 is disposed on the first bracket head 1, and the first positioning groove is disposed on the adapter 2; the second positioning block is disposed on the second bracket head 3, and the second positioning groove 202 is disposed on the adapter 2, which is worth noting that, since the adapter 2 needs to be provided with multiple sets, the processing of the grooves (i.e. the first positioning groove and the second positioning groove 202) on the multiple sets of adapters 2 is easier than the setting of the protruding blocks (i.e. the first positioning block 101 and the second positioning block), and the processing efficiency is improved.
It should be readily understood that, in other embodiments of the present utility model, the first positioning block 101 and the second positioning block may be disposed on the adapter 2, and the first positioning groove may be disposed on the first bracket head 1 and the second positioning groove 202 may be disposed on the second adapter 2, respectively, regardless of the machining efficiency.
The number and/or shape of the first positioning block 101 and the second positioning block are different, that is, the number and/or shape of the first positioning groove and the second positioning groove 202 are different, it is worth to be noted that the arrangement is convenient to distinguish which end of the adapter 2 is connected with the first bracket head 1 and which end is connected with the second bracket head 3, that is, quick installation is convenient. Specifically, the number and shape of the first positioning block 101 are different from each other, specifically, the first positioning block 101 is rectangular and provided with two positioning blocks, and the second positioning block is rectangular and provided with one positioning block.
It is to be understood that in other embodiments of the present utility model, both the first positioning block 101 and the second positioning block may be the same, different in number, or the same, different in shape, and the same object may be achieved.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
