Embodiment Construction

[0024] figure 1 , figure 2 A first embodiment of the invention is shown.

[0025] Such as figure 1 As shown, the anti-loosening locking structure includes a locked piece 1, a locking piece 2, a bolt 3, and a nut 4. The locked piece 1 and the locking piece 2 are correspondingly provided with a first through hole 10 and a second through hole 10 that communicate with each other. Two through holes 20, the end of the first through hole 10 away from the locking member 2 is a countersunk hole, the bolt 3 runs through the first through hole 1 and the second through hole 2, and the nut 4 is located in the countersunk hole and connected to the bolt 3 Cooperate. Such as figure 2 As shown, the anti-off member 5 is an L-shaped elastic member, and a pin hole 11 is provided on the side of the locked part, and the end of the short side 51 of the anti-off member 5 is provided with a barb 53 embedded in the pin hole 11, The length of the short side 51 is equal to the distance from the pi...

Abstract

The invention relates to an anti-loosing locking structure and a projection lamp provided with the same. The locking structure comprises a locking part, a locked part, a bolt, a nut, an anti-loosing element and a fastening element, wherein the locked part and the locking part are correspondingly provided with a first through hole and a second through hole which are communicated with each other, one tip of the first through hole away from the locking part is a counter sink, the bolt passes through the first through hole and the second through hole, the nut is arranged in the counter sink and is matched with the bolt, the anti-loosing element is fastened on the locked part and covers the counter sink, the fastening element is arranged in the counter sink, and the two ends of the fastening element are respectively in contact with the nut and the anti-loosing element. The locking structure can effectively prevent the problem that the nut is dropped, thus causing that the locking fails; and when being applied to a projection lamp, the locking structure can effectively prevent loss caused by invalid locking between a lamp holder and a lamp shade fails.

Description

technical field [0001] The invention relates to a locking structure, more specifically, to an anti-loosening locking structure and a projection lamp with the locking structure. Background technique [0002] As a commonly used fastener, bolts and nuts are widely used in various fields. When applied to frequently moving and vibrating objects, the nut will fall off from the bolt after long-term use, causing two locks to fail and cause losses. For example, in a projection lamp, in order to effectively protect the bulb and electrical components of the projection lamp and prolong the service life of the projection lamp, the bulb and electrical components are generally sealed and installed in a projection lamp box composed of a lamp holder and a lampshade; The light bulb and the electrical components are easy to install, and the lamp holder and the lampshade are fastened and connected by bolts and nuts. Projection lamps are widely used in motor vehicles, ships, naval vessels, avi...
