Description

Technical Field

[0001] This utility model relates to the field of flashlight technology, and in particular to an anti-loosening structure and a flashlight. Background Technology

[0002] Most conventional flashlights on the market consist of a body and a tail, relying on the tight connection between the body and the tail to achieve the function of connecting the circuit. However, during use, accidental drops often cause the two parts to loosen, leading to malfunction. Therefore, it is necessary to propose an anti-loosening structure after the product is dropped. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides an anti-loosening structure and a flashlight.

[0004] An anti-loosening structure includes two annular sheets, one of which is a male fastener and the other is a female fastener;

[0005] The front side of the female buckle is provided with a plurality of first protrusions, which are arranged at even intervals, and a limiting groove is formed between two adjacent first protrusions.

[0006] The male buckle has a second protrusion on its front side that matches the groove; a notch is provided on the front side of the male buckle at a predetermined distance from the second protrusion;

[0007] The back of the male buckle and the back of the female buckle are respectively used to connect with two preset objects; when the front of the male buckle corresponds to the front of the female buckle and is rotated to a preset angle, the second protrusion is inserted into a limiting groove, so that the male buckle and the female buckle interlock with each other and the two preset objects are fastened together.

[0008] A flashlight includes a body and a tail, and an anti-loosening structure as described above; the back of the male buckle is connected to the tail, and the back of the female buckle is connected to the body; or, the back of the female buckle is connected to the tail, and the back of the male buckle is connected to the body.

[0009] The anti-loosening structure and flashlight provided by this utility model achieve a tight fastening of the body and tail by interlocking two protrusions on the male and female buckles. At the same time, the limiting groove is designed as an unequal-sided inverted triangle, with different slopes on the left and right sides, making it relatively easy to screw the body and tail into place when they are rotated, and relatively difficult to detach when they are separated. Thus, when the flashlight is dropped, it can prevent the body and tail from loosening and avoid affecting the function of the flashlight. Attached Figure Description

[0017] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Provides an anti-loosening structure and a flashlight, such as Figures 1 to 5 As shown, the anti-loosening structure is used in flashlights, but is not limited to this. The anti-loosening structure includes two annular sheets, the material of which is not limited. One sheet is a male buckle 2, and the other sheet is a female buckle 1. The male and female buckles are used together. The front of the female buckle has a plurality of first protrusions 11, which are evenly spaced and form a limiting groove 12 between adjacent first protrusions. The front of the male buckle has a second protrusion 21 that matches the groove. A notch 22 is provided on the front of the male buckle at a predetermined distance from the second protrusion.

[0019] The shapes of the first and second protrusions are not limited, as long as the second protrusion can form a matching engagement with the limiting groove. In use, the back of the male buckle and the back of the female buckle are respectively used to connect with two preset objects. When the front of the male buckle aligns with the front of the female buckle and is rotated to a preset angle, the second protrusion engages in a limiting groove, causing the male and female buckles to engage and the two preset objects to be fastened together. Simultaneously, a notch is provided next to the second protrusion to facilitate a certain amount of spring force when the male and female buckles separate, allowing them to separate after engagement.

[0020] Furthermore, the male buckle has a hollowed-out area 23 extending towards the second protrusion at the notch. This hollowed-out area increases the deformation around the notch, making it easier to loosen or tighten the male and female buckles. Preferably, the hollowed-out area is arc-shaped, and its area gradually decreases from the notch towards the second protrusion.

[0021] Furthermore, the cross-section of the limiting groove is an inverted triangle. In this inverted triangle, the angle between the left waist edge 121 and the horizontal line is greater than the angle between the right waist edge 122 and the horizontal line. The side containing the right waist edge is the direction in which the male and female buckles engage, while the side containing the left waist edge is the direction in which they disengage. That is, the left and right waist edges form different slopes. The gentler slope is the direction in which the male and female buckles engage, making them relatively easy to engage; simultaneously, the steeper slope is the direction in which they disengage, making them relatively difficult to detach. Understandably, the angles between the left and right waist edges and the horizontal line can be interchanged, but the side with the smaller angle to the horizontal line remains the direction in which the male and female buckles engage, while the other side is the direction in which they disengage.

[0022] Preferably, taking the angle between the left waist edge and the horizontal line as greater than the angle between the right waist edge and the horizontal line as an example, the left waist edge, with the vertex 123 of the base corner of the inverted triangle as the center, deviates from the vertical line by an angle of less than 40°; the right waist edge, with the vertex of the base corner of the inverted triangle as the center, deviates from the vertical line by an angle of less than 70°. That is, the male and female buckles achieve the optimal fastening and separation effect.

[0023] The flashlight includes a body 3 and a tail 4, as well as the anti-loosening structure described above. In the anti-loosening structure, the back of the male buckle 2 is glued to the tail, and the back of the female buckle 1 is glued to the body. Finally, the tail is screwed into the body. When screwed to a certain position, the protrusions on the male and female buckles begin to interlock until they are fully engaged. Due to the anti-loosening structure, the body and tail are less likely to come loose when the flashlight is dropped, thus providing protection. Alternatively, the male and female buckles can be connected to the body and tail respectively, achieving the same effect, which will not be elaborated upon here.

[0024] The above is a description of the present utility model to help understand it; however, the implementation of the present utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
