Description

Technical Field

[0001] This invention relates to the field of portable lighting fixtures, and more specifically to a portable three-way lamp device. Background Technology

[0002] Portable lighting is an indispensable piece of equipment for outdoor activities, with common applications including academic exploration, natural energy extraction, livestock farming, and wilderness emergency rescue. Existing portable lighting includes two types: the first type is a headlamp without adjustable beam angle, such as the headlamp disclosed in CN219263996U, but this structure is relatively simple; the second type is an adjustable headlamp, mainly composed of a lamp, an adjustment component, and a mounting base, such as the portable multi-functional lighting work headlamp disclosed in application number 2012200271654. This headlamp achieves angle adjustment by rotating the entire lamp outward through the adjustment component. However, in actual use, it has been found that when the beam angle is adjusted downwards, the lamp rotates outwards and downwards, causing a significant downward sensation for the user, affecting wearing comfort. Furthermore, in the second type, the stress on the adjustment component is often only on the pivot part, making it prone to breakage and resulting in poor connection stability. Summary of the Invention

[0003] To address the above problems, the present invention provides a portable three-way lamp device:

[0004] A portable three-way lamp device includes a flexible bracket and a three-way lamp fixture. The three-way lamp fixture includes a three-way tube body, a battery assembly, a control assembly, and a lamp holder, which are electrically connected in sequence. The three-way tube body includes a horizontal tube body and an integrally radially fixed intermediate tube head connected to the middle of the horizontal tube body. The horizontal tube body has a cavity for accommodating the battery assembly and the control assembly. The lamp holder is installed in the intermediate tube head. The flexible bracket includes a base body and a C-shaped flexible clamp fixedly connected to the surface of the base body. The C-shaped flexible clamp and the horizontal tube body form a detachable flexible locking engagement. When the C-shaped flexible clamp and the horizontal tube body are in flexible locking engagement, the horizontal tube body can rotate relative to the C-shaped flexible clamp.

[0005] Preferably, there are two C-type elastic clamps arranged symmetrically. When the C-type elastic clamps are elastically engaged with the transverse pipe body, the two C-type elastic clamps are located on the left and right sides of the middle pipe head.

[0006] Preferably, the transverse tube body is provided with an annular locking groove adapted to a C-type elastic clamp, and the annular locking groove is symmetrically arranged on the surface of the transverse tube body relative to the middle tube head. The annular locking groove can prevent the C-type elastic clamp from slipping relative to the axial direction of the transverse tube body.

[0007] Preferably, the seat has an arc-shaped sheet structure, and an elastic strap adapted to fit the human head is threaded through the seat. The arc-shaped sheet structure of the seat better fits the human head and improves comfort.

[0008] Preferably, one C-shaped elastic clamp is provided, and an elastic clip is provided on the back of the seat. The elastic clip of this technical solution can clamp clothing, such as a chest pocket, to allow for the wearing of the corresponding lamp.

[0009] Preferably, the control component is installed at one end of the transverse tube. The control component includes a control board, a charging connector, and a push-button switch. The control board is electrically connected to the push-button switch, the battery assembly, and the charging connector, respectively.

[0010] Preferably, the button switch and the charging head are each equipped with a flexible waterproof plug.

[0011] Preferably, the transverse tube body is detachably sealed with a threaded connection and has an elastic waterproof outer cover. The elastic waterproof outer cover seals and covers the control components and is provided with an elastic waterproof membrane adapted to the push-button switch.

[0012] Preferably, the transverse tube is detachably threadedly connected to an end cap, and the transverse tube and the end cap constitute a chamber cavity.

[0013] Beneficial effects: First, this application allows the transverse tube to rotate relative to the C-shaped elastic clamp, thereby adjusting the flip angle of the middle tube head. Since the lamp head is installed inside the middle tube head, the lamp illumination angle can be adjusted.

[0014] Secondly, the center of gravity of this three-way lamp is mainly in the horizontal tube. During the process of flipping the horizontal tube relative to the elastic bracket, the entire lamp will not tend to move outward. Therefore, it has good wearing comfort in actual use.

[0015] Third, the three-way light fixture and the flexible bracket are connected by a horizontal tube and a C-shaped flexible clamp, ensuring good connection stability regardless of how the user adjusts the rotation angle of the three-way light fixture, thus preventing the adjustment components from breaking.

[0020] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described with reference to Examples 1-2.

[0021] Example 1: This Example 1 is a head-mounted portable three-way lamp device, including a flexible bracket and a three-way lamp. The three-way lamp includes a three-way tube, a battery assembly, a control assembly, and a lamp head. The battery assembly, control assembly, and lamp head are electrically connected in sequence. The three-way tube includes a horizontal tube and an integrally radially fixed intermediate tube head connected to the middle of the horizontal tube. The horizontal tube has a cavity for accommodating the battery assembly and control assembly. The lamp head is installed in the intermediate tube head. The flexible bracket includes a base and a C-shaped flexible clamp fixedly connected to the surface of the base. The C-shaped flexible clamp and the horizontal tube form a detachable flexible locking engagement. When the C-shaped flexible clamp and the horizontal tube are in elastic locking engagement, the horizontal tube can rotate relative to the C-shaped flexible clamp.

[0022] Two C-type elastic clamps are provided and symmetrically arranged. When the C-type elastic clamps are elastically engaged with the transverse pipe body, the two C-type elastic clamps are located on the left and right sides of the middle pipe end. The transverse pipe body is provided with annular locking grooves adapted to the C-type elastic clamps. The annular locking grooves are symmetrically arranged on the surface of the transverse pipe body relative to the middle pipe end. The annular locking grooves can prevent the C-type elastic clamps from slipping relative to the axial direction of the transverse pipe body.

[0023] The seat has an arc-shaped, sheet-like structure, and an elastic strap is threaded through it to fit the human head. The arc-shaped, sheet-like seat better fits the human head, improving comfort.

[0024] The control component is installed at one end of the transverse tube. The control component includes a control board, a charging connector, and a push-button switch. The control board is electrically connected to the push-button switch, the battery assembly, and the charging connector. The push-button switch and the charging connector are each equipped with a flexible waterproof plug. The lamp head is connected to the middle tube head in a sealed and waterproof manner. The transverse tube is detachably threaded with an end cap, and the transverse tube and the end cap form a cavity.

[0025] Example 1 already provides standard waterproofing; however, for deep-water diving, a removable, threaded, elastic waterproof cover can be attached to the transverse tube. This elastic waterproof cover seals and covers the control components and includes an elastic waterproof membrane adapted to the push-button switch. The structure of the elastic waterproof cover achieves complete coverage of the push-button switch and charging connector, thus providing better waterproofing. The user can directly press the push-button switch through the elastic waterproof membrane.

[0026] Example 2: This example 2 is based on a chest-worn portable three-way lamp device, including a flexible bracket and a three-way lamp. The three-way lamp includes a three-way tube, a battery assembly, a control assembly, and a lamp head. The battery assembly, control assembly, and lamp head are electrically connected in sequence. The three-way tube includes a horizontal tube and an integrally radially fixed intermediate tube head connected to the middle of the horizontal tube. The horizontal tube has a cavity for accommodating the battery assembly and control assembly. The lamp head is installed in the intermediate tube head. The flexible bracket includes a base and a C-shaped flexible clamp fixedly connected to the surface of the base. The C-shaped flexible clamp and the horizontal tube form a detachable flexible locking engagement. When the C-shaped flexible clamp and the horizontal tube are in elastic locking engagement, the horizontal tube can rotate relative to the C-shaped flexible clamp.

[0027] The structure of Embodiment 2 is similar to that of Embodiment 1, except that there is only one C-shaped elastic clamp, and an elastic clip is provided on the back of the seat. The elastic clip of Embodiment 2 can clamp clothing, such as in a chest pocket, to allow for the wearing of the corresponding lamp.

[0028] Obviously, the above embodiments of the present invention are merely illustrative examples and not intended to limit the implementation of the invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. However, these obvious variations or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
