Embodiment Construction
[0015] As shown in Figures 1, 2, and 3, the automatic locking folding rod connector includes inner joint 3, outer joint 4, left locking ear piece 5, right locking ear piece 6, and hinge shaft 7; the rod to be locked It is the front rod 1 and the rear rod 2.
[0016] One end of the inner joint 3 is a chamfered surface, and both sides are L-shaped flanges, which are set and fixed with the front rod 1; one end of the outer joint 4 is also a chamfered plane, and the angle of the chamfered plane is complementary to that of the inner joint 3; The locking lug 5 and the right locking lug 6 are bent inward at a small angle, and fixed symmetrically (for example, by welding) on the left and right sides of the outer joint 4; The joint 3 and the outer joint 4 are hinged by a hinge shaft 7 .
[0017] When the front bar 1 and the rear bar 2 are folded, the inner joint 3 and the outer joint 4 are folded back to back; when the front bar 1 and the rear bar 2 are unfolded, the inner joint 3 a...

The invention discloses an automatic locked folding rod piece connector. An inner joint and an outer joint are sleeved and fixed with a connected rod piece respectively, one hinged side of the inner joint and the outer joint is a diagonal plane, and two sides of the inner joint are L-shaped bent sides; the angle of the diagonal plane of the outer joint is complementary with the angle of the diagonal plane of the inner joint; a left locking lug and a right locking lug are symmetrically fixed at two sides of the diagonal plane of the outer joint, and parts of the left locking lug and the right locking lug extending out of the outer joint are bent inwards; during expanding, the inner joint and the outer joint rotate around a hinged part, and the L-shaped bent sides at the two sides of the inner joint expand and pass through the inner bent sides of the left locking lug and the right locking lug; and the diagonal plane of the inner joint is attached to the diagonal plane of the outer joint, and the inner bent sides of the left locking lug and the right locking lug block the L-shaped bent sides at the two sides of the inner joint so that a front rod piece and a back rod piece cannot rotate so as to realize the locking of the rod piece. The automatic locked folding rod piece connector overcomes the defects of the prior art, and has the advantages of light weight, simplicity and reliability; and by using the folding rod piece connector, the locking has no clearance, and the expansion repeating precision of the rod piece is high.
Description
technical field [0001] The present invention relates to a folding rod connector, especially an automatic locking folding rod connector, which can be used as a deployment locking mechanism of a rod-shaped deployment locking mechanism or the like. Background technique [0002] The folding rod-shaped unfolding locking mechanism is an important mechanism commonly used on satellites. The connecting parts usually use hinges and specially arranged locking parts to complete the unfolding and locking of the rods. The connecting parts have many parts and are heavy. [0003] "Folding rod connector" (patent notification number CN2729394, date of announcement on September 28, 2005) is composed of a first connecting part and a second connecting part, the outer end of the first connecting part is provided with a slot, the opening The side wall of the groove is provided with a fixing hole, the second connecting piece is inserted into the slot, and a long slot hole is arranged on it, and a h...
