Description

Technical Field

[0001] The utility model relates to the technical field of lighting flashlights, in particular to a flashlight that is flexible to use. Background Art

[0002] Flashlights are an indispensable lighting tool in people's lives, but existing flashlights are all straight-cylindrical in shape, and their irradiation direction is fixed forward. When a user wants to change the direction of the lighting light, the entire flashlight needs to be adjusted, and the structure, appearance and practicality are very simple. To this end, relevant technical personnel have developed a flashlight that can be rotated, such as a rotatable flashlight disclosed in the utility model patent with Chinese patent number CN201620632784.4, which includes a barrel head, a barrel neck and a barrel body. The barrel head includes a turning head and a turning upper seat positioned in the turning head, and the barrel neck includes a neck and a turning lower seat positioned in the neck. The angle between the plane formed by the contact between the neck and the turning head and the axis of the barrel body is between 30° and 60°. A positioning platform extends from the middle of the turning upper seat and is inserted into the central through hole of the turning lower seat, and is axially fixed in place by a buckle. The neck is tightly matched with the contact points of the turning upper seat and the turning head respectively. Since the barrel head can be rotated 360° along an inclined plane relative to the barrel body, the function of a corner light is added while satisfying the flashlight function, so that users do not need other additional accessories when hiking at night. After the rotation angle, it can be directly hung on a backpack, pocket, chest, waist, etc. to free their hands. However, after the barrel head is rotated relative to the barrel body, a shielding surface will be formed between the two, as shown in the above-mentioned public document Figure 4 , Figure 5 As shown, the existence of the blocking surface not only affects the integrity of the appearance of the flashlight, but also causes problems such as collision and cutting of the user's hands when the user uses it, thereby causing injury to the user. In addition, the blocking surface will also cause a certain degree of line of sight obstruction, affecting the user's observation of things.

[0038] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0039] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0040] See also Figure 1-Figure 19 The present invention discloses a flexible flashlight, comprising a barrel body 1 and a barrel head 2 which can rotate relative to the barrel body 1. The barrel body 1 is provided with a barrel body section 1.1, and the barrel head 2 is provided with a barrel head section 2.1. The barrel body section 1.1 and the barrel head section 2.1 are mutually dependent and remain overlapped when the barrel body 1 and the barrel head 2 are rotated to any position.

[0041] In this embodiment, the rotation between the barrel 1 and the barrel head 2 is utilized so that the user can change the direction of the illumination light by rotating the position between the barrel head 2 and the barrel 1 without adjusting the entire flashlight, so as to facilitate the user's lighting use and improve the user experience. At the same time, when the barrel 1 and the barrel head 2 are rotated to any position, the barrel cross section 1.1 always keeps coincidence with the barrel head cross section 2.1, thereby effectively avoiding the obstruction surface between the barrel 1 and the barrel head 2 during rotation, thereby reducing a series of problems such as collision, cutting hands, and obstruction of vision that occur during use of the user, so as to further improve the user's use experience and have strong practicality.

[0042] Specifically, the barrel head 2 can rotate arbitrarily between 0 and 360 degrees relative to the barrel body 1, and the two can form a stepless rotation positioning or a step-by-step rotation positioning of 0 to 360 degrees, thereby avoiding problems such as accidental displacement of the barrel head 2 and the barrel body 1 after rotation, thereby improving the stability of the flashlight. The barrel body cross section 1.1 and the barrel head cross section 2.1 always remain overlapped during the rotation process and positioning.

[0043] The outer contours of the barrel section 1.1 and the barrel head section 2.1 are both circular, so that when the barrel 1 and the barrel head 2 are rotated to any position, the barrel section 1.1 always overlaps with the barrel head section 2.1 to avoid the appearance of an obstruction surface.

[0044] The barrel cross section 1.1 and the barrel head cross section 2.1 are both planes, and the two achieve rotational positioning through friction. Since the barrel cross section 1.1 and the barrel head cross section 2.1 are both planes and rely on each other, the barrel cross section 1.1 and the barrel head cross section 2.1, which are both planes, can achieve rotational positioning through the friction area after relying on each other, thereby achieving stepless rotational positioning of the barrel head 2 relative to the barrel body 1 in the range of 0-360 degrees.

[0045] Alternatively, the shape of the barrel cross section 1.1 and the shape of the barrel head cross section 2.1 are concave-convex surfaces, and the two achieve rotational positioning through the concave-convex. Since the shape of the barrel cross section 1.1 and the shape of the barrel head cross section 2.1 are concave-convex matching surfaces, and the two rely on each other, therefore, when the concave-convex matching barrel cross section 1.1 and the barrel head cross section 2.1 rely on each other, they can achieve rotational positioning through the concave-convex matching area, thereby realizing the step-by-step rotational positioning of the barrel head 2 relative to the barrel body 1 in the range of 0-360 degrees.

[0046] Specifically, the barrel 1 is provided with a barrel connecting portion 1.2, which is elliptical, and the barrel cross-section 1.1 is a plane and is transversely truncated at the barrel connecting portion 1.2. The barrel head 2 is provided with a barrel head connecting portion 2.2, which is elliptical, and the barrel head cross-section 2.1 is a plane and is transversely truncated at the barrel head connecting portion 2.2.

[0047] In this embodiment, the barrel connecting portion 1.2 is located at the end of the barrel 1, and the barrel cross-section 1.1 is transversely cut at 45 degrees on the barrel connecting portion 1.2, so that the barrel cross-section 1.1 is a plane and the outer contour is circular. The barrel head connecting portion 2.2 is located at the end of the barrel head 2, and the barrel head cross-section 2.1 is transversely cut at 45 degrees on the barrel head connecting portion 2.2, so that the barrel head cross-section 2.1 is a plane and the outer contour is circular. At the same time, when the barrel 1 and the barrel head 2 rotate with each other, the axes of the two are matched at an angle of 0-360 degrees.

[0048] A barrel body positioning portion 1.3 is provided on the barrel body section 1.1, and a barrel head positioning portion 2.3 is provided on the barrel head section 2.1. The barrel body positioning portion 1.3 and the barrel head positioning portion 2.3 are both circular in shape, and the two are rotationally positioned and matched.

[0049] Furthermore, the barrel body positioning portion 1.3 is a circular positioning protrusion, and is convexly arranged at the center position of the barrel body section 1.1 along the axis of the barrel body section 1.1, the barrel head positioning portion 2.3 is a circular positioning hole, and is concavely arranged at the center position of the barrel head section 2.1 along the axis of the barrel head section 2.1, and the barrel body positioning portion 1.3 is positioned on the barrel head positioning portion 2.3.

[0050] The barrel body positioning part 1.3 and the barrel head positioning part 2.3 are assembled by positioning sleeve connection, which has a simple structure and convenient assembly, and can also effectively ensure the positioning between the barrel body 1 and the barrel head 2.

[0051] A barrel body limiting guide portion 1.4 is provided on the barrel body 1, the barrel body section 1.1, or the barrel body positioning portion 1.3; a barrel head limiting guide portion 2.4 is provided on the barrel head 2, the barrel head section 2.1, or the barrel head positioning portion 2.3; the barrel body limiting guide portion 1.4 and the barrel head limiting guide portion 2.4 are matched in a rotational limiting guide manner.

[0052] In this embodiment, the barrel limiting guide portion 1.4 is a groove and is concavely arranged along the outer arc of the barrel positioning portion 1.3. The barrel head limiting guide portion 2.4 is a convex shaft. The side of the barrel head 2 is provided with an assembly hole 2.6, and the assembly hole 2.6 passes through the barrel head positioning portion 2.3. The barrel head limiting guide portion 2.4 is assembled on the assembly hole 2.6, and its inner end extends into the barrel head positioning portion 2.3, and slides along the trajectory of the barrel body limiting guide portion 1.4 when the barrel body 1 and the barrel head 2 rotate, so that the barrel body 1 and the barrel head 2 can be limited and guided during the rotation process, which not only improves the rotation stability of the two, but also ensures that the two will not fall off.

[0053] Since the barrel limiting guide part 1.4 is an arc-shaped groove and the size of the arc is semicircular, the barrel 1 and the barrel head 2 can be reciprocated and rotated between 0-180 degrees for limiting guidance.

[0054] A barrel body seal is provided on the barrel body 1, the barrel body section 1.1, or the barrel body positioning portion 1.3, and / or a barrel head seal 3 is provided on the barrel head 2, the barrel head section 2.1, or the barrel head positioning portion 2.3. The barrel body 1 and the barrel head 2 are sealed and rotated with each other through the barrel body seal and / or the barrel head seal 3.

[0055] In this embodiment, the barrel body positioning portion 1.3 is provided with a first positioning groove 1.6 and a second positioning groove 1.7, a certain distance is formed between the first positioning groove 1.6 and the second positioning groove 1.7, the barrel body seal is provided with two, and respectively is a first barrel body seal 14 and a second barrel body seal 15, the first barrel body seal 14 and the second barrel body seal 15 are respectively positioned and sleeved on the first positioning groove 1.6 and the second positioning groove 1.7, the barrel head cross section 2.1 is provided with a third positioning groove 2.7, the barrel head seal 3 is positioned and arranged on the third positioning groove 2.7, and the barrel body 1 and the barrel head 2 are connected by the first barrel body seal The cooperation of the first barrel seal 14, the second barrel seal 15 and the barrel head seal 3 forms a triple seal, thereby effectively preventing moisture from entering the interior of the flashlight from the gap between the barrel body 1 and the barrel head 2, thereby ensuring the stability of the flashlight. In addition, the first barrel seal 14, the second barrel seal 15 and the barrel head seal 3 are positioned by the first positioning groove 1.6, the second positioning groove 1.7 and the third positioning groove 2.7 respectively, thereby effectively avoiding the problem of displacement of the first barrel seal 14, the second barrel seal 15 and the barrel head seal 3 when the barrel body 1 and the barrel head 2 are rotated, thereby ensuring the sealing stability of the flashlight.

[0056] A battery cavity and a barrel body lighting lamp assembly cavity are provided on the barrel body 1. A power source 4 is provided in the battery cavity. The power source 4 is a rechargeable battery and / or a detachable battery. The barrel body 1 is provided with a charging port and / or a disassembly port corresponding to the rechargeable battery and / or the detachable battery.
