Embodiment Construction

[0022] The present invention is further described in detail below by connecting the accompanying drawings in a specific embodiment. It should be noted herein that the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation of the present invention. Further, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0023] See Figures 1 to 5 The figure shows the anti-loosening mechanism of the spindle adaptive torque thread connection in the signal lamp, which can be used for the operation control panel of aircraft, ships, etc.

[0024] The anti-loosening mechanism is mainly composed of lamp base body 1, signal card body 2, mandrel base body 3, lower mandrel body 4, upper mandrel body 5 and tower spring 6 and other components.

[0025] The lamp base body 1 has a lamp base perimete...

Abstract

The invention discloses a mandrel self-adaptive torque threaded connection anti-loosening mechanism in a signal lamp. The mandrel self-adaptive torque threaded connection anti-loosening mechanism is composed of a lamp holder body, a signal board body, a mandrel seat body, a lower mandrel body, an upper mandrel body, a tower-shaped spring and the like. The self-adaptive torque threaded connection structure has the beneficial effects that in the assembling and tightening process, the self-adaptive torque threaded connection is formed through relative circumferential rotation between the lower section of the lower core shaft and the inner circumferential wall of the core shaft seat, the tightening torque is self-adaptively constant and is not increased any more, and threaded connection threads are protected against failure caused by too large tightening torque.

Description

Technical field [0001] The present invention relates to a signal lamp, in particular, a signal lamp in the mandrel adaptive torque thread connection anti-loosening mechanism. Background [0002] Aircraft, ships, etc. operate control panels, and the two-segment mandrel in the signal light is prone to screws. Contents of the Invention [0003] The present invention to solve the problems in the prior art, to provide a new type of signal lamp in the core shaft adaptive torque thread connection anti-loosening mechanism. [0004] To achieve this object, the technical scheme of the present invention is as follows: signal lamp in the core shaft adaptive torque threaded connection anti-loosening mechanism, comprising, [0005] Lamp base body, which has a lamp base perimeter wall and by the lamp base perimeter wall to define the built-in space of the lamp base through up and down, the lamp base perimeter wall of the inner perimeter of the lamp base to form a lamp base upper groove and a l...
