Description

Technical Field

[0001] The present invention 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-cylinder-shaped, and their illumination direction is fixed forward. When users want to change the direction of the lighting light, they need to adjust the entire flashlight. The structure, appearance and practicality are very simple. To this end, relevant technical personnel have developed a flashlight that can be rotated, such as the utility model patent with Chinese patent number CN201620632784.4, which discloses a rotatable flashlight. It includes a tube head, a tube neck and a tube body. The tube head includes a turning head and a turning upper seat positioned in the turning head. The tube 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 tube 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 position by a buckle. The neck is tightly matched with the contact points of the turning upper seat and the turning head respectively. Since the tube head can be rotated 360° along the inclined plane relative to the tube 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 tube head is rotated relative to the tube 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 flashlight's appearance, but also causes problems such as collisions and cuts when the user is using it, which may cause injuries 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.

[0037] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] See also Figures 1-19 The present invention provides a flexible flashlight, comprising a barrel 1 and a barrel head 2 rotatable 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 rely on each other and remain overlapped when the barrel body 1 and the barrel head 2 are rotated to any position.

[0040] 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 lighting 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 remains coincident 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 may occur during use of the user, thereby further improving the user experience and being highly practical.

[0041] Specifically, the barrel head 2 can rotate arbitrarily between 0 and 360 degrees relative to the barrel body 1, and the two form a stepless rotation positioning or a step-by-step rotation positioning of 0 to 360 degrees. In this way, the barrel head 2 and the barrel body 1 can be prevented from accidentally shifting 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 coincident during the rotation process and positioning.

[0042] 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 remains overlapped with the barrel head section 2.1, avoiding the appearance of an obstruction surface.

[0043] The barrel cross section 1.1 and the barrel head cross section 2.1 are both planes, and the two are rotated and positioned by 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 be rotated and positioned by the friction area after relying on each other, thereby realizing stepless rotation positioning of the barrel head 2 relative to the barrel body 1 in the range of 0-360 degrees.

[0044] 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 and 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 step-by-step rotational positioning of the barrel head 2 relative to the barrel body 1 in the range of 0-360 degrees.

[0045] Specifically, the barrel 1 is provided with a barrel connecting portion 1.2, which is elliptical, the barrel cross-section 1.1 is flat and transversely truncated at the barrel connecting portion 1.2, and the barrel head 2 is provided with a barrel head connecting portion 2.2, which is elliptical, the barrel head cross-section 2.1 is flat and transversely truncated at the barrel head connecting portion 2.2.

[0046] 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.

[0047] 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. Both the barrel body positioning portion 1.3 and the barrel head positioning portion 2.3 are circular in shape, and the two are rotationally positioned and matched.

[0048] 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 cross section 1.1 along the axis of the barrel body cross 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 cross section 2.1 along the axis of the barrel head cross section 2.1; the barrel body positioning portion 1.3 is positioned on the barrel head positioning portion 2.3.

[0049] The barrel body positioning portion 1.3 and the barrel head positioning portion 2.3 are assembled by adopting a positioning sleeve connection method, which has a simple structure and is easy to assemble, while also effectively ensuring the positioning between the barrel body 1 and the barrel head 2.

[0050] 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, and 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 with each other in a rotational limiting guide manner.

[0051] 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, which 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 are limited and guided during the rotation process, which not only improves the rotational stability of the two, but also ensures that the two will not fall off.

[0052] Since the barrel limiting guide portion 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 limited between 0-180 degrees.

[0053] A barrel 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.

[0054] In this embodiment, a first positioning groove 1.6 and a second positioning groove 1.7 are provided on the barrel positioning portion 1.3, a certain distance is formed between the first positioning groove 1.6 and the second positioning groove 1.7, and two barrel seals are provided, namely, a first barrel seal 14 and a second barrel seal 15, the first barrel seal 14 and the second barrel seal 15 are respectively positioned and sleeved on the first positioning groove 1.6 and the second positioning groove 1.7, a third positioning groove 2.7 is provided on the barrel head cross section 2.1, and the barrel head seal 3 is positioned and arranged on the third positioning groove 2.7, and the barrel 1 and the barrel head 2 are connected by the first barrel seal. 14, the second barrel seal 15, and the barrel head seal 3 cooperate to form 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, 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.

[0055] The barrel body 1 is provided with a battery cavity and a barrel body lighting lamp assembly cavity, and a power supply 4 is provided in the battery cavity. The power supply 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. A waterproof part 5 is disassembled on the charging port, and a cover plate 6 is disassembled on the disassembly port. A barrel body lighting lamp 7 is provided inside the barrel body lighting lamp assembly cavity. The side of the barrel body lighting lamp assembly cavity is open and a barrel body light-transmitting plate 8 is fixed thereto. A splint 9 is provided on the barrel body 1.

[0056] The tube head 2 is provided with a tube head lighting lamp assembly cavity 10 , inside which a tube head lighting lamp 11 is arranged. The top of the tube head lighting lamp assembly cavity 10 is open and a tube head light-transmitting plate 12 is fixed.

[0057] In this embodiment, the power source 4 can be a rechargeable battery or a detachable battery. The user can charge the rechargeable battery through the charging port, and can also disassemble and replace the detachable battery through the disassembly port. Multiple power supply modes are convenient for users to use. The user can use the splint 9 to clamp the flashlight and position it in a backpack, clothes, pants, etc., and can use the tube body lighting lamp 7 on the side of the tube body 1 for lighting, or use the tube head lighting lamp 11 on the top of the tube head 2 for lighting. The arrangement of the tube body light-transmitting plate 8 and the tube head light-transmitting plate 12 is conducive to the light of the tube body lighting lamp 7 and the tube head lighting lamp 11, and can also protect the tube body lighting lamp 7 and the tube head lighting lamp 11.

[0058] The barrel body 1 is provided with a barrel body wiring through-hole 1.5, and the barrel head 2 is provided with a barrel head wiring through-hole 2.5. The barrel head wiring through-hole 2.5 is connected with the barrel body wiring through-hole 1.5, thereby allowing the power cord on the power supply 4 located on the barrel body 1 to enter the barrel head 2 through the barrel head wiring through-hole 2.5 and the barrel body wiring through-hole 1.5, and be electrically connected to the barrel head lighting lamp 11, ensuring that the barrel head lighting lamp 11 can obtain electricity and work.

[0059] A control button 13 is also provided on the barrel body 1 and / or the barrel head 2.

[0060] In this embodiment, the control button 13 is set on the barrel body 1, and the user can control the barrel body lighting light 7 and the barrel head lighting light 11 through the control button 13, which is convenient to use.
