Description

TECHNICAL FIELD

[0001] The utility model relates to photography equipment technical field, concretely is a hot shoe adapter that can quick assembly and disassembly. BACKGROUND

[0002] In the photography field, the external flash is often connected with the camera through the hot shoe. However, in some shooting scenes (such as portrait and still photography), the position of the flash needs to be raised to achieve a softer light effect or to avoid lens shadow, so the hot shoe adapter is used as a connecting component between the camera hot shoe and the flash.

[0003] At present, the hot shoe adapter on the market is mainly connected with the camera hot shoe through a plug-in structure, but due to the size tolerance of the hot shoe groove or the wear caused by long-term use, the plug is prone to looseness or even fall off, affecting the stability. To solve this problem, the existing technology mainly adopts a screw compression type fixing scheme, that is, a liftable compression seat is arranged on the adapter, and the compression seat is pressed down on the top of the hot shoe by rotating the screw, so as to enhance the fixing effect. However, this screw compression method needs to be screwed several times (usually several turns) to compress or loosen, which is low in efficiency in the scene of frequently disassembling and assembling the flash or adjusting the angle.

[0004] Therefore, there is an urgent need for a hot shoe adapter structure that can be quickly disassembled and stably locked, which can simplify the operation steps and improve the efficiency of the photography workflow while ensuring reliable load bearing. UTILITY MODEL CONTENTS

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figs. 1-7 A quick-release hot shoe adapter includes a top connector 2 and a bottom connector plate 13. The connector 2 contains a contact plate 1, which is electrically coupled to the connector plate 13. A base 3 is fixedly connected to the bottom of the connector 2. An annular seat 4 is provided on the lower surface of the base 3. A rotating sleeve 15 is fitted over the annular seat 4. A core seat 6 is installed inside the annular seat 4. A liftable pressure seat 10 is slidably installed below the core seat 6. A pair of guide posts 11 on the top of the pressure seat 10 are slidably installed in a pair of guide holes 14 on the core seat 6. A pair of locking screws are threaded to the top of the guide holes 14. A spring 9 is fitted on the nail 8 and the locking screw 8. The head of the locking screw 8 and the spring 9 are both restricted above the base 3. The pressure seat 10 extends from the lower port of the annular seat 4 and the diameter of the pressure seat 10 is larger than the diameter of the lower port of the annular seat 4. A clearance hole 12 is provided at the center of the pressure seat 10. A boss 7 is provided at the bottom of the core seat 6. The boss 7 extends from the clearance hole 12. The plug plate 13 is fixedly connected to the bottom of the boss 7. A spiral inclined surface 5 is provided on the circumferential side wall of the core seat 6. A contact button 19 is provided on the annular seat 4. The contact button 19 abuts against the lower surface of the spiral inclined surface 5.

[0021] The rear side of the spiral inclined surface 5 is provided with a spiral groove 16. The upper and lower ends of the groove 16 are respectively provided with an upper opening 18 and a lower opening 17. The contact button 19 is a spring-loaded button that can be pressed from the outside. One end of the contact button 19 that extends into the rotating sleeve 15 is provided with an upwardly extending groove hook 20. The groove hook 20 slides in conjunction with the groove 16.

[0022] Working principle of this embodiment:

[0023] With the rotating sleeve 15 in the unlocked state, the slot hook 20 is engaged in the groove 16, and the pressure seat 10 is in a high position under the elastic force of the spring 9. The plug plate 13 remains separated from the camera hot shoe groove, making it easy to insert or remove quickly. After inserting the plug plate 13 into the camera hot shoe groove, rotate the rotating sleeve 15 clockwise, causing the spiral inclined surface 5 of the core seat 6 to rotate. The spiral inclined surface 5 pushes the guide post 11 of the pressure seat 10 to move down along the guide hole 14, compressing the spring 9, so that the pressure seat 10 presses down to the top of the hot shoe, achieving mechanical fixation (the pressure seat (10) and the top surface of the hot shoe form a friction lock).

[0024] When the slot hook 20 reaches the lower opening 17, the contact button 19 is automatically ejected, and the slot hook 20 is locked into the upper opening 18 to lock the rotating sleeve 15, preventing it from loosening. At this time, the pressure seat 10 is at the maximum downward stroke. Press the contact button 19, and the slot hook 20 exits the upper opening 18 and reenters the groove 16, unlocking the rotating sleeve 15. Rotate the rotating sleeve 15 counterclockwise, and the helical slope 5 releases the pressure. The spring 9 pushes the pressure seat 10 upward to reset, the plug-in board 13 is separated from the hot shoe slot, and one-key disassembly is achieved.

[0025] Traditional screwing requires multiple turns of the screw 8, while the present embodiment only needs to rotate about half a turn through the helical slope 5 of the rotating sleeve 15 to complete locking / release, significantly improving operational efficiency and being suitable for frequent disassembly scenarios. The locking mechanism of the slot hook 20 and the lower opening 17 avoids the rotating sleeve 15 from retreating due to vibration, ensuring that the pressure seat 10 continuously presses the hot shoe and solving the problem of easy loosening of the traditional plug-in structure. The spring 9 provides constant downward pressure, compensating for the size tolerance or wear of the hot shoe slot, avoiding the tedious operation of manually adjusting the screw 8 repeatedly.
