Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0018] The present invention will be described in further detail below. see figure 1 , a strut including a strut body 1 (see figure 2 ) and strut joint 3 (see Figure 4 ), characterized in that it also includes a sleeve 2 (see image 3 ), toothed stop 4 (see Figure 5 ), single-ear tooth washer 5 (see Image 6 ), double lug flat washer 6 (see Figure 7 ) and spring 7, the sleeve 2 is divided into a load-bearing part, an adjustment part and an anti-loosening part (see image 3 ), the inner diameter of the anti-loosening part and the adjusting part is larger than the inner diameter of the load-bearing part, the load-bearing part and the anti-loosening part are both internal thread structures, and the thread directions of the two parts are opposite (see Figure 8 ), two "L"-shaped slots are symmetrically opened on the pipe wall of the regulating part; the toothed...

Abstract

The invention discloses a brace rod which comprises a brace rod body and a brace rod joint and is characterized by also comprising a sleeve, a tooth-shaped stop body, a single-ear tooth-shaped washer, a double-ear flat washer and a spring, wherein the sleeve is divided into a bearing part, an adjusting part and an anti-loosening part; the inner diameters of the anti-loosening part and the adjusting part are greater than the inner diameter of the bearing part; the bearing part and the anti-loosening part are both an internal thread structure, and the thread directions of the two parts are opposite; two L-shaped clamp slots are symmetrically formed in the pipe wall of the adjusting part; the tooth-shaped stop body is of a tubular structure with an end surface at one end; the end surface at the other end of the tubular structure is of a tooth-shaped structure; the outer side of the pipe wall is of a thread structure, and the thread direction is the same as that of the anti-loosening part of the sleeve; the inner diameter of the tubular structure is greater than the thread outer diameter of the brace rod joint. The brace rod disclosed by the invention can realize connection between the brace rod joint and the sleeve, loosening prevention of the thread through mutual exclusion of positive and negative threads as well as quick adjustment of length and quick disassembly through a compression spring, and has the advantages of high adjustment precision, convenience in adjustment and disassembly and the like.

Description

technical field [0001] The invention belongs to aircraft structural design, in particular to a strut that can realize rapid and continuous adjustment. Background technique [0002] The struts commonly used in aircraft structures are made of ordinary stop washers or stop blocks, lock nuts and fuses to prevent loosening. The adjustment amount is limited to one-half, one-quarter or one-sixth of the pitch. , it is not easy to meet the conditions for parts that require high adjustment accuracy. And every adjustment and disassembly must remove the fuse, which is inconvenient to use. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a strut that can quickly adjust the length of the load-bearing strut, and can ensure high adjustment accuracy; and is easy to use, adjust and disassemble. [0004] The technical solution of the present invention is: a strut, comprising a strut body 1 and a strut joint 3, and is characterized in that it also include...
