Description

Technical Field

[0001] The utility model relates to the technical field of light bulb cameras, and more particularly to an angle-adjustable light bulb camera extension rod. Background Art

[0002] A lightbulb camera is a surveillance device shaped like a lightbulb. Currently, these cameras often require an extension rod. This is because when working outdoors, the lamp base is often covered with a cap. When the lightbulb camera is screwed in too far, the image being monitored by the cap is blocked. Therefore, an extension rod is often added to increase the distance between the lightbulb camera and the cap, preventing the image from being obstructed.

[0003] However, the extension rods on the market cannot be adjusted after installation. If the angle cannot be adjusted, when the bulb camera is screwed into the lamp holder and tightened to the bottom, if the camera is facing the wall or is not the angle you want to monitor, you need to disassemble it and readjust the installation angle, which is very inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is described in further detail below. The embodiments of the present invention are provided for purposes of illustration and convenience of description and are not intended to be exhaustive or to limit the present invention to the disclosed embodiments. Numerous modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0022] like Figure 1-Figure 5As shown, the present invention provides an adjustable angle bulb camera extension rod, comprising an upper rod body 1, an intermediate rod body 2, and a lower connector 3 connected to the bulb camera, arranged sequentially from top to bottom. The upper rod body 1 includes a plastic housing 11 and an inner connecting sleeve 12 located within the plastic housing 11. The upper rod body 1 is connected to the lamp holder, and the lower connector 3 is connected to the bulb camera. The extension rod of this solution serves as an intermediate body, extending the distance between the bulb camera and the lamp holder to prevent the image from being blocked by the brim of a hat. At the same time, the angle of the installed bulb camera can be adjusted, providing flexible use.

[0023] The intermediate rod body 2 is movably connected to the upper rod body 1, and the bottom of the upper rod body 1 extends into the intermediate rod body 2. A connecting piece and a clamping piece are provided in the intermediate rod body 2. The bottom of the upper rod body 1 is provided with a limit piece corresponding to the connecting piece and a plurality of snap-in positions corresponding to the clamping piece. The connecting piece is slidably connected to the limit piece. The plurality of snap-in positions are evenly arranged on the outer circumference of the upper rod body 1, and the clamping piece is compatible with any of the snap-in positions.

[0024] The connecting piece and the limiting piece cooperate to connect the intermediate rod body 2 to the upper rod body 1, while ensuring that the intermediate rod body 2 can rotate. The clamping piece cooperates with the snap position and is locked in the snap position. The intermediate rod body 2 cannot rotate in its natural state. When the intermediate rod body 2 is manually rotated, the clamping piece can move from its corresponding snap position to another snap position and be fixed. Through this structure, the angle of the intermediate rod body 2 can be adjusted without disassembly.

[0025] The limiting member includes an annular limiting platform 4 located outside the upper rod body 1, and the connecting member includes a plurality of connecting blocks 5 spaced apart within the intermediate rod body 2, with the connecting blocks 5 located above the annular limiting platform 4. The annular limiting platform 4 limits the connecting blocks 5, achieving the connection between the intermediate rod body 2 and the upper rod body 1, while not affecting the movement of the connecting blocks 5 on the annular limiting platform 4. In this embodiment, three connecting blocks 5 are provided and evenly distributed to ensure connection stability.

[0026] The snap-fitting locations include recessed notches 6, several of which are arranged in a wavy pattern around the outer periphery of the upper rod 1. The snap-fitting components include snap-fitting strips that mate with the notches 6. The intermediate rod 2 is also constructed of plastic, providing a degree of elasticity. The outer surface of the snap-fitting strips 7 is curved, as is the connection between adjacent notches 6. This arrangement ensures that the snap-fitting strips 7 can be smoothly moved from one notch 6 to the other under external force, preventing any jamming during rotation. In this embodiment, there are three snap-fitting strips 7, evenly distributed.

[0027] The upper rod 1 is also equipped with a positioning block 8 on the outside, and a positioning block 9 is installed inside the intermediate rod 2, corresponding to the positioning block 8. Positioning blocks 8 and 9 cooperate, and when positioning blocks 8 and 9 come into contact, rotation stops. The positioning blocks 8 and 9 allow for precise rotation angles and protect the internally connected power cables. In this embodiment, the maximum rotation angle of the intermediate rod 2 relative to the upper rod 1 is 355°.

[0028] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
