Embodiment Construction

[0018] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings:

[0019] Such as figure 1 Shown is a three-dimensional schematic diagram of the present invention.

[0020] Such as figure 2 Shown is a schematic diagram of the explosive bolt structure of the present invention. The left end of the explosive bolt is a thread, the right end is a socket for electrical connection, and the socket of the socket is recessed. The thread specification is M12, which is connected to the life-saving buoy 1. Inside the explosive bolt, it is connected to the built-in high explosive through a lead wire. After the bolt exploded, after cutting off the shear pin, the threaded end was ejected out of the machine with the life-saving buoy 1, while the remaining part of the bolt remained in the fixed separation device 3.

[0021] Such as Figure 3 ~ Figure 5 Shown is a schematic structural diagram of the compensation mechanism of the explosi...

Abstract

The invention provides a limit compensation mechanism of an explosive bolt separation device, the mechanical structure of which includes fastening a support base (4) on a separation fixing base (3) with screws (13), and securing a socket box with screws (12). (6) Fastened on the support seat (4); its electrical structure includes an external plug seat (9) and a two-core plug (11), wherein the external plug seat (9) is connected to the two-core plug through a power filter (10) On the plug (11), the two-core plug (11) is connected to the socket end of the explosion bolt (5) by direct insertion to complete electrical connection; between the two-core plug (11) and the socket box (6), a certain The floating limit structure of the gap (h). The invention solves the problem that the explosive bolt has a simple structure and sufficient mechanical strength, and also ensures very reliable explosive separation. It is very convenient to install and replace in the outfield and infield, reliable in work and good in disassembly and replacement.

Description

Technical field [0001] The invention belongs to the technical field of explosive bolts, and relates to electrical connections with fixed axial positions but uncertain circumferential positions, and in particular to a limit compensation mechanism of an explosive bolt separation device. Background technique [0002] Aviation life-saving buoy products need to be actively or passively separated from the body to achieve life-saving or positioning when in distress. The separation uses the method of explosive bolt and electric explosion separation. Explosive bolts are electrically activated, and generally use lead wires at the non-connected end to achieve power-up. Because explosive bolts are life-span sensitive components, they need to be replaced every year after installation. During installation, the wires are easily broken and fail; in addition, a power filter must be connected at the entry end of the explosive bolts to ensure reliable and effective electrical connection .
