Embodiment Construction

[0012] figure 1 It is a prior art, a schematic diagram of the structure of a separation nut for reverse unlocking direct-push aircraft components; the device includes: an outer cylinder 106 and a blocking cap 102 to form a housing; an igniter 105 is installed on both sides of the end of the outer cylinder 106; An inner cylinder 110 is installed in the cylinder 106 and fixed with a locking pin 104; there is a certain gap between the rear end of the inner cylinder 110 and the outer cylinder. Inside the inner cylinder 110, a ball head b108, a split nut 109, a ball head a112 and a locking rod 101 are sequentially installed; the locking rod 101 is inserted into the split nut 109 and connected with threads; Connected as a whole, the locking rod 101 protrudes out of the casing through the blocking cap 102 , and the stopper 111 is positioned between the split nut 109 and the inner cylinder 110 . Sealing rings 107 and 103 are respectively provided between the outer cylinder 106 and th...

Abstract

The invention discloses an aircraft component separation nut, which comprises: an igniter sleeve [6] is installed on the lower end of a housing [2], and an igniter stop pad [7] is installed on the igniter sleeve [6], and two Igniter; the actuator [4] and the split nut [3] are installed in sequence in the housing [2], fixed with the locking pin [10]; the locking rod [1] is installed in the split nut [3] ; One end of the locking rod [1] protrudes from the upper end of the casing [2]; between the igniter sleeve [6] and the casing [2], between the casing [2] and the actuator [4] A sealing ring is provided. The invention can bear greater external load, has a simple and compact structure, and achieves beneficial effects such as simple movement, small axial impact, large locking force, no pollution, and high reliability during the separation process.

Description

technical field [0001] The invention relates to a separation nut of an aircraft component, in particular to a separation nut used for locking and releasing satellite large-load antennas and solar cell arrays, or connecting and separating rockets and arrows. Background technique [0002] The locking and releasing of existing satellite antennas or solar cell arrays mostly use pyrotechnic cutters. Due to the limited cutting ability of the cutters, the maximum locking force that can be provided is limited. As the size of satellite related antennas becomes larger and larger, the requirements for locking loads are also greater, and the cutting capacity of existing cutters cannot meet the requirements. If the working principle of cutters continues to be used, their dimensions and weight will increase greatly. Adapt to the characteristics of small quality and low impact required by satellite products. [0003] In the 1980s, relevant low-impact, non-polluting pyrotechnic locking and...
