Description

Technical Field

[0001] The utility model relates to a screw-on human body infrared sensing lens structure. Background Art

[0002] Prior art, such as Chinese utility model patent document, publication number CN213930843U, discloses an LED lamp with an infrared induction controlled switch, comprising an upper shell and a lower shell, the upper shell and the lower shell being connected by screws, a placement cavity being formed between the upper shell and the lower shell, a PCB circuit board being installed in the placement cavity, an infrared sensor, a light sensor and a transformer being arranged on the PCB circuit board, a mounting hole being provided on the upper end surface of the upper shell corresponding to the position of the infrared sensor and the light sensor, an infrared lens being arranged in the mounting hole, a plug being provided on the lower end surface of the lower shell, the plug being electrically connected to the PCB circuit board, a light cover being plugged into the right ends of the upper shell and the lower shell, an LED light board being arranged in the light cover, and the LED light board being electrically connected to the PCB circuit board.

[0003] Based on the above, in the prior art, infrared sensors need to be used with lenses. Existing infrared lenses are generally installed in the mounting holes of the housing and assembled by snap-fitting. Although snap-fitting installation can be assembled without tools and has high assembly efficiency, in the later stage of user use, when the lens is damaged due to bumps or other factors, the buckle snapped in the mounting hole is difficult to disengage, and the user is often required to smash the entire lens and then separate the buckle. Disassembly is very difficult and needs further improvement. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a screw-on human infrared sensing lens structure.

[0005] A screw-on human infrared sensing lens structure designed for this purpose comprises a panel and a lens, wherein the panel is provided with a mounting hole penetrating from front to back, a plurality of screw-on grooves are provided in the hole wall of the mounting hole, the screw-on grooves comprise a connecting groove provided in the mounting hole, the two ends of the connecting groove are respectively connected with a limiting groove and a slot, the front end of the slot is open, and a plurality of limiting protrusions which can be inserted into the slot and can be screwed into the limiting groove through the connecting groove are provided on the peripheral wall of the lens;

[0006] An elastic element is arranged on the panel, and the elastic element is used to apply a force to the lens so that the limiting protrusion is kept in the limiting groove.

[0007] Preferably, the elastic element comprises a mounting ring, on which a plurality of elastic sheets are arranged, and the positions of the elastic sheets correspond to the positions of the screw-on grooves;

[0008] The elastic sheet abuts against the rear end surface of the lens.

[0009] Preferably, a plurality of positioning protrusions are provided on the front surface of the elastic sheet, and the positioning protrusions abut against the rear end surface of the lens.

[0010] Preferably, the mounting ring is provided with a through hole, and a screw is passed through the through hole to be fixedly connected to the panel.

[0011] Preferably, the mounting ring and the elastic sheet are an integrated structure and are made of metal.

[0012] Compared with the prior art, the utility model adopts a screw-on assembly. When the lens is rotated so that the limiting protrusion comes to the slot, the lens can be moved forward to separate the lens from the mounting hole. In the assembled state, the lens moves backward so that the limiting protrusion is inserted backward into the slot until the limiting protrusion is plugged into the rear end of the slot. In this process, the elastic element is compressed to store force. Then the lens is rotated so that the limiting protrusion comes to the rear end of the limiting slot through the connecting groove. At this time, when the user releases the lens, the elastic element releases the stored force and pushes the limiting protrusion into the front end of the limiting slot to constrain the limiting protrusion in the limiting slot. Thereby, the locking installation of the lens is completed. The utility model adopts an elastic element in combination with a screw-on assembly to avoid the problem of difficulty in disassembly at a later stage. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Based on the above embodiment, in the assembled state, the lens moves backwards, so that the limiting protrusion is inserted backwards into the slot until the limiting protrusion is plugged into the rear end of the slot. In this process, the elastic element is compressed to store force. Then the lens is rotated so that the limiting protrusion comes to the rear end of the limiting slot through the connecting groove. At this time, when the user releases the lens, the elastic element releases the stored force and pushes the limiting protrusion into the front end of the limiting slot to constrain the limiting protrusion in the limiting slot. Thus, the locking installation of the lens is completed.
