Description

Technical Field

[0001] The utility model relates to the technical field of flashlight lampshade structures, in particular to a quick-install flashlight lampshade structure. Background Art

[0002] In the design of traditional flash lampshades, threaded connection is a common installation method. This design achieves stable installation of the lampshade by opening a threaded groove on the flash body and matching it with the corresponding thread on the lampshade. However, although the threaded connection ensures the stability of the lampshade to a certain extent, strong vibrations or accidental collisions in outdoor or complex shooting environments may also cause the threaded connection to fail, causing the lampshade to fall off, causing unnecessary interference to shooting and even damaging the equipment.

[0003] Traditional flash lampshades are usually installed on the flash lamp head by screw fixing, snap connection or glue bonding. Although the screw fixing method is stable, it requires tools to assist in the installation and removal process, which increases the complexity and time cost of the operation. Although the snap connection simplifies the installation process to a certain extent, in some designs, the snap structure is complex and difficult to align, resulting in low installation efficiency. Glue bonding has the problems of non-reusability and inconvenient replacement. In addition, the glue may age and fail after long-term use, affecting the stability of the lampshade and increasing the work burden of the photographer. Therefore, developing a quick-release flash lampshade structure to solve the defects of the traditional structure in terms of convenience has become an urgent problem to be solved in the industry.

[0028] See also Figure 1-Figure 3 As shown, a quick-install flashlight lampshade structure comprises a quick-connection installation mechanism 2 threadedly connected to a threaded opening of a flashlight body 1 and a threaded locking groove 11, a clamping groove 12 and a contact sleeve 13 provided on the flashlight body 1. The quick-connection installation mechanism 2 comprises a split lampshade 21 and a pair of contact pieces 22 arranged on the split lampshade 21 and in contact with the contact sleeve 13, and a pushing block 23 slidably arranged in the split lampshade 21 in a horizontal straight direction and in contact with the clamping groove 12, and a driving mechanism 3 driving the pushing block 23 to slide in a horizontal straight direction. The split lampshades 21 are respectively provided with a pair of threaded connection blocks 211, and the pair of threaded connection blocks 211 are provided with threaded locking rods 212. The threaded locking rods 212 are used to quickly dock and install the split lampshades 21, so as to achieve quick installation of the split lampshades 21 to adapt to flashlight bodies 1 of different sizes.

[0029] When the split lampshade 21 needs to be quickly installed on the flash body 1, the threaded installation chamber 31 provided on the split lampshade 21 is first aligned with the position of the threaded locking groove 11 provided on the flash body 1, and then the split lampshade 21 is rotated until the split lampshade 21 is threadedly installed on the flash body 1. During the process of rotating and installing the split lampshade 21, the contact sleeve 13 can be brought into contact with the contact sheet 22. After the contact, the contact sheet 22 can be driven, and the pushing block 23 can be driven by the contact driving mechanism 3 to slide in a horizontal straight line direction until the pushing block 23 is engaged in the slot 12 provided on the flash body 1, thereby achieving the effect of quickly installing the split lampshade 21 on the flash body 1, enhancing the stability of the connection, and simplifying the installation and disassembly process.

[0030] See also Figure 1-Figure 3 As shown, the driving mechanism 3 includes a threaded mounting chamber 31, a sliding chamber 32 and a positioning plate 33; the threaded mounting chamber 31 is opened on the split lampshade 21; the sliding chamber 32 is opened on the split lampshade 21 and has a pair; the positioning plate 33 is arranged in the sliding chamber 32.

[0031] When the split lampshade 21 needs to be quickly installed on the flash body 1, the threaded installation chamber 31 is first docked on the flash body 1. During the installation process, the pushing block 23 can be driven to contact the contact sleeve 13, and during the contact process, the pushing block 23 is driven to move out of the outside of the sliding chamber 32 and contact the card slot 12 to achieve the threaded connection and fixation of the split lampshade 21 and the flash body 1 after the threaded connection, thereby improving the stability of the connection.

[0032] See also Figure 3 As shown, the driving mechanism 3 also includes a moving rod 34, a return spring 35, a limiting rod 36 and a hinged rod 37; the moving rod 34 is slidably arranged on the positioning plate 33 in the vertical direction, the moving rod 34 is fixedly connected to the contact piece 22, and the positioning plate 33 is used to limit the vertical sliding of the moving rod 34; the return spring 35 is arranged on the moving rod 34, and the two ends of the return spring 35 are respectively fixed to the ends of the moving rod 34 and the positioning plate 33; the limiting rod 36 is arranged in the sliding chamber 32, and the limiting rod 36 is clearance-matched with the pushing block 23; the hinged rod 37 is rotatably arranged on the pushing block 23 and the moving rod 34 respectively.

[0033] When the contact sleeve 13 contacts the pushing block 23, the moving rod 34 and the contact piece 22 can be driven to descend in the vertical direction along the positioning plate 33 with clearance fit. During the descending movement, the rotating hinge rod 37 can be driven to tilt and swing the pushing block 23. During the tilting and swinging, the pushing block 23 can be driven to slide in the horizontal straight line direction along the limiting rod 36 until the pushing block extends out of the outside of the sliding chamber 32 and contacts and fixes the card slot 12. At this time, the pushing block 23 can be moved into the card slot 12, thereby achieving the effect of improving the stability of the connection between the split lampshade 21 and the flash body 1.

[0034] See also Figure 3-Figure 8 As shown, the driving mechanism 3 further includes a limiting groove 38 and a sliding block 39 ; the limiting groove 38 is opened in the sliding chamber 32 and has a pair; the sliding block 39 is slidably arranged on the limiting groove 38 , and the sliding block 39 is fixedly connected to the pushing block 23 .

[0035] When the pushing block 23 slides in the horizontal straight direction along the limiting rod 36, the sliding block 39 can be driven to slide stably in the horizontal straight direction along the limiting groove 38 during this process. Since the sliding block 39 is fixedly connected to the pushing block 23, the pushing block 23 can slide stably in the horizontal straight direction, thereby achieving a stable sliding limiting effect on the pushing block 23.
