Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to a hanging lamp with adjustable position. Background Art

[0002] The existing hanging lamps usually cannot adjust the lighting direction after installation. When a certain angle of the room needs to be illuminated, other lamps can only be used.

[0003] Therefore, adjustable angle hanging lighting fixtures came into being. The most common adjustment method is to adjust the angle of the fixture through a universal ball joint. In existing universal ball joint fixtures, the fixture is mostly fixed by friction, that is, the friction of the universal ball joint must be greater than the gravity of the fixture, or it is fixed by a tightening fastener.

[0004] However, the prior art has the following problems:

[0005] 1. The structure of the universal ball joint that relies on friction cannot support the direction adjustment of large-sized and heavy lamps. If the friction is increased, the operator will use more force to twist the universal ball joint when manually adjusting, and the universal ball joint fixed with tightening fasteners requires the operator to tighten. Both adjustment methods require the operator to operate with great force, increasing the risk of falling during off-the-ground operation;

[0006] 2. After repeated use, the universal ball joint will be severely worn, which will cause the friction to decrease and gradually lose the adjustment function. Utility Model Content

[0007] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a suspension lamp with adjustable position to solve the problem that the existing universal ball joint cannot support the direction adjustment of large-sized and heavy lamps, and after repeated use, the universal ball joint is severely worn, resulting in a decrease in friction and a gradual loss of adjustment function.

[0014] The fixing rod is fixedly mounted on the bottom surface of the housing, and a third through hole is provided on the fixing rod, and the axis of the third through hole is perpendicular to the axis of the fixing rod;

[0015] Locking rod; under normal conditions, the connecting rod and the lamp are both set in the mounting groove, and the first end of the locking rod is set below one end of the luminous surface of the lamp after passing through the third through hole. When the position of the lamp needs to be adjusted, remove the locking rod, and with the cooperation of the connecting rod and the universal ball joint, the lamp falls out of the mounting groove, adjust the universal ball joint to the required angle, and then pass one end of the locking rod through the two first through holes and one second through hole in sequence. At this time, the locking rod limits the universal ball joint, and the adjustment of the lamp position is completed.
