Projection lamp limited by elastic piece

Abstract

The projection lamp comprises a projection lamp body and an n-shaped installation base, and semicircular protrusions are arranged on the symmetrical side edges of the projection lamp body. A limiting tooth groove is formed in the edge of the semicircular bulge; the inner side face of a vertical plate of the n-shaped installation base is provided with an abutting elastic piece. A vertical plate of the n-shaped mounting base is attached to the outer surface of the semicircular protrusion and connected with the semicircular protrusion through a bolt, and the abutting elastic piece abuts against one limiting tooth groove to be limited; when the external force is larger than the friction force between the abutting elastic piece and the limiting tooth grooves, the abutting elastic piece jumps between the adjacent limiting tooth grooves. The structure arrangement is reasonable, when the n-shaped installation base and the circular protrusion rotate relatively, the bolt does not need to be tightened or loosened, rotation can be achieved only by enabling external force to be larger than resistance between the abutting elastic piece and the limiting tooth groove under the action of the external force, abutting limiting can be conducted through the abutting elastic piece when the external force does not exist, and the structure is simple and convenient. The stability and reliability of angle adjustment are improved, and angle adjustment operation is facilitated.

Description

Technical Field

[0001] This utility model belongs to the field of floodlight technology, specifically relating to a floodlight with spring-loaded limiting mechanism. Background Technology

[0002] Floodlights, also known as spotlights, are mainly used for architectural and decorative lighting. They have good monochromaticity and low power consumption, and are easy to assemble. Current LED floodlights are mostly adjusted and fixed by tightening or loosening bolts when adjusting the illumination angle. Although this allows for adjustment, it is not very convenient to operate, and they are prone to loosening or falling off after repeated use, which limits their applicability. Utility Model Content

[0003] The purpose of this invention is to provide a floodlight with a spring-loaded limiter that has a reasonable structural design and is conducive to angle positioning.

[0004] The technical solution to achieve the purpose of this utility model is a floodlight with spring-loaded limiting, including a floodlight body and an n-shaped mounting base. The symmetrical sides of the floodlight body are integrally formed with semi-circular protrusions.

[0005] The semi-circular protrusion has equally spaced positioning grooves along its edge.

[0006] The inner side of the vertical plate of the n-shaped mounting base is provided with a stop spring;

[0007] The vertical plate of the n-shaped mounting base is attached to the outer surface of the semi-circular protrusion and connected by bolts, and the abutment spring is abutted in one of the limiting tooth grooves for limitation;

[0008] When the external force is greater than the friction between the pressing spring and the limiting tooth groove, the n-shaped mounting base rotates with the bolt as the fulcrum, and the pressing spring jumps between adjacent limiting tooth grooves.

[0009] A further preferred embodiment is that the abutment spring is a stainless steel sheet with a thickness of 1-2 mm.

[0010] A further preferred embodiment is that the length of the pressing spring is greater than the thickness of the semi-circular protrusion.

[0011] A further preferred embodiment is that the bottom surface of the pressure spring is an arc-shaped surface.

[0012] A further preferred embodiment is that: the outer wall of the semi-circular protrusion is radially provided with anti-slip grooves, and the inner side of the vertical plate of the n-shaped mounting base is provided with anti-slip ridges;

[0013] The anti-slip ridges are attached to the anti-slip grooves.

[0014] This utility model has the following positive effects: Its structure is reasonably designed, with a limiting groove on the edge of the semi-circular protrusion, which works in conjunction with a stop spring on the vertical plate of the n-shaped mounting base. Therefore, when the n-shaped mounting base rotates relative to the circular protrusion, there is no need to tighten or loosen the bolts. Rotation can be achieved simply by ensuring that the external force exceeds the resistance between the stop spring and the limiting groove. Furthermore, in the absence of external force, the stop spring can provide pressure and limit, improving the stability and reliability of angle adjustment, facilitating angle adjustment operations. It is also simple to manufacture, reducing processing costs and difficulty, and has strong applicability. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] See Figures 1 to 3As shown, a floodlight with spring-loaded positioning includes a floodlight body 1 and an n-shaped mounting base 2. The floodlight body has a semi-circular protrusion 3 integrally formed on its symmetrical sides. In this embodiment, the above structures are conventional structures of the prior art, simply applied. In actual application, the edges of the semi-circular protrusions are provided with equally spaced limiting grooves 4. A retaining spring 5 is provided on the inner side of the vertical plate of the n-shaped mounting base. In this embodiment, the retaining spring is a stainless steel sheet with a thickness of 1-2 mm. It can be integrally formed with the n-shaped mounting base, fixed by welding, or fixed by screws, etc. During assembly, the vertical plate of the n-shaped mounting base is attached to the outer surface of the semi-circular protrusion and connected by bolts. The retaining spring is positioned within one of the limiting grooves. Moreover, when the external force is greater than the frictional force between the retaining spring and the limiting groove, the n-shaped mounting base rotates around the bolt as a fulcrum, and the retaining spring bounces between adjacent limiting grooves. With the above structure, the stop spring can be engaged in the limiting tooth groove to limit the position, which improves the stability and reliability of use. Moreover, when the external force is greater than the resistance between the stop spring and the limiting tooth groove, the angle can be adjusted. When there is no external force, the two can be used for limiting.

[0023] In practical applications, the length of the pressure spring is greater than the thickness of the semi-circular protrusion. Furthermore, to improve the effectiveness of rotation, the bottom surface of the pressure spring is arc-shaped. The outer wall of the semi-circular protrusion is radially provided with anti-slip grooves 6, and the inner side of the vertical plate of the n-shaped mounting base is provided with anti-slip ridges 7; the anti-slip ridges are attached to the anti-slip grooves. The anti-slip grooves and anti-slip ridges increase the resistance of both, improving the stability and effectiveness of use.

[0024] This utility model has the following positive effects: Its structure is reasonably designed, with a limiting groove on the edge of the semi-circular protrusion, which works in conjunction with a stop spring on the vertical plate of the n-shaped mounting base. Therefore, when the n-shaped mounting base rotates relative to the circular protrusion, there is no need to tighten or loosen the bolts. Rotation can be achieved simply by ensuring that the external force exceeds the resistance between the stop spring and the limiting groove. Furthermore, in the absence of external force, the stop spring can provide pressure and limit, improving the stability and reliability of angle adjustment, facilitating angle adjustment operations. It is also simple to manufacture, reducing processing costs and difficulty, and has strong applicability.

[0025] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
