Background

In an aircraft such as a rocket and the like, a structure is frequently provided, and after the installation positions of two parts with higher positioning precision are determined, a support part needs to be added between the two parts to ensure the integral rigidity of the structure.

It is common practice to design the support as a fixed length part; during assembly, after the positions of the two supported parts are determined, the length of the supported part is modified or an adjusting shim is added between the supported part and the supported part, so that the gap between the supported part and the supported part is eliminated, and the supporting rigidity is ensured. The assembly mode has the defects of poor manufacturability, low assembly efficiency, difficult complete clearance elimination and the like.

Disclosure of Invention

An adjustable support device, a serial communication port, the device by one of support piece, by two, supporting mechanism to and bracing piece, nut and support nut constitute.

And a supporting mechanism is arranged on one of the supported member and the supported member, the supporting mechanism can be a flange or a support lug, and a mounting hole for connecting the supporting rod is arranged on the supporting mechanism (i.e. the flange or the support lug).

The supporting rod is of a rod-shaped structure and is arranged between the supporting mechanisms of the first supported part and the second supported part; the middle part of the supporting rod can be designed into a cylinder or a polygon prism according to the structural requirement; the two ends of the supporting mechanism are respectively provided with external threads, and the external diameter of the threads is slightly smaller than the mounting holes of the supporting mechanisms on the first supported part and the second supported part; the thread diameter of one end A is smaller than the size of the cross section of the middle part of the support rod, and a step structure is formed to serve as a support surface; the diameter of the thread at the other end B can be determined according to the structural requirement, and the length of the thread is longer than that at the other end, so that the installation is convenient. The number of the supporting rods can be determined according to the size of the supported part and the rigidity required to be supported, and is usually 2-30.

The nut and the supporting nut can be made of standard parts or self-made parts, and a flat washer and a spring washer can be assembled for preventing the nut from loosening according to requirements.

The utility model discloses a use as follows:

after the mounting positions of the first supported part and the second supported part are determined, fixing one of the supported parts (taking the first supported part as an example); installing a support nut at the B end of the support rod, rotating the support nut to the root of the thread, inserting the B-end thread parts of the support rods into the installation holes of the two support mechanisms of the supported piece (at the moment, the length of the support rod between the first supported piece and the second supported piece is ensured to be smaller than the distance between the first supported piece and the second supported piece so as to ensure that the A end of the support rod can be inserted into the installation hole of the one support mechanism of the supported piece), and fixing the second supported piece; then a plurality of A ends of the support rods are respectively inserted into the mounting holes of the support mechanism of one of the supported parts, nuts are respectively mounted at the tail ends of the A ends of the support rods and are screwed and attached to the flange plate or the support lug of one of the supported parts, and finally the support nuts at the B ends of the support rods are screwed towards the two directions of the supported parts and are attached to the flange plate or the support lug of the two supported parts. To this end, the support rod provides effective support for one of the support members and the supported member by virtue of the tightening force of the support nut.

According to the utility model discloses a strutting arrangement compares with prior art, mainly possesses following technical advantage:

1. the support length of the support rod can be adjusted through threads, the problem that the length of a support piece needs to be repaired or adjusted by an adjusting gasket in the assembling process is solved, and the assembling efficiency and the connection reliability are improved;

2. the use of internal threads is avoided, and the support rigidity can be improved by using a limited space.

Detailed Description

An adjustable support device, its characterized in that, the device by one of support piece 1, by two 2 of support piece, supporting mechanism 6 to and bracing piece 3, nut 4 and support nut 5 constitute.

The supporting mechanism 6 is arranged on the supported member 1 and the supported member 2, the supporting mechanism 6 can be a flange or a lug, and the supporting mechanism 6 (i.e. the flange or the lug) is provided with a mounting hole 7 for connecting with the supporting rod 3.

The support rod 3 is generally made of metal and has a rod-shaped structure; the middle part of the glass can be designed into a cylinder or a polygon prism according to the structural requirement; two ends of the supporting mechanism are respectively provided with external threads with certain lengths, and the external diameter of the external threads is slightly smaller than the mounting holes 7 of the supporting mechanisms 6 on the first supported part 1 and the second supported part 2; the thread diameter of one end A is smaller than the size of the middle section of the support rod 3, and a step structure is formed to serve as a support surface; the diameter of the thread at the other end B can be determined according to the structural requirement, and the length of the thread is longer than that at the other end, so that the installation is convenient. The number of the support rods 3 can be determined according to the size of the supported part and the rigidity of the required support, and is usually 2-30.
