[0022] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0023] A bayonet locking structure for a top light, comprising a lamp holder 1, a rotating member 11 and a bayonet member 3, wherein the lamp holder 1 is provided with the rotating member 11, a notch 2 is provided on the rotating member 11, and a first groove is provided in the notch 2, and a second groove is provided on the bayonet member 3, and a protrusion 32 is fixedly connected to the bayonet member 3 and located on the side of the second groove;

[0024] like Figure 1-3 As shown, the rotating member 11 is installed on the front shell of the lamp holder 1 by screws and is located on the peripheral side of the light outlet of the lamp holder 1. A plurality of notches 2 are evenly arranged on the rotating member 11, and the first groove is connected to the notch 2. At the same time, the position of the second groove corresponds to the position of the notch 2. With one side of the bayonet member 3 located at the second groove as the reference plane, the height of the protrusion 32 is greater than the height of the second notch 31.

[0025] During installation, the protrusion 32 on the bayonet member 3 is extended into the notch portion 2, and then the bayonet member 3 is rotated to move the protrusion 32 from the notch portion 2 to the No. 1 groove. The notch portion 2 and the No. 2 groove are staggered to press the protrusion 32 tightly, thereby achieving the limitation of the protrusion 32 in the vertical direction, so that the bayonet member 3 is installed on the rotating member 11. Compared with the existing installation method, the utility model improves the stability and reliability of the installation between the bayonet member 3 and the rotating member 11, reduces the possibility of plastic accessories falling off or shaking during use, and is conducive to improving the shooting effect.

[0026] As a possible implementation of this solution, preferably, Figure 2 As shown, a spring nail 4 is arranged in the notch portion 2, and the spring nail 4 is used to strengthen the limiting of the protrusion 32; the spring nail 4 can telescopically move on the rotating member 11, and when the spring nail 4 is squeezed, the spring nail 4 will retract into the rotating member 11, and vice versa, when the spring nail 4 is not squeezed, the spring nail 4 will extend out of the rotating member 11, and when the protrusion 32 moves to the No. 1 groove, the spring nail 4 is located on the side of the protrusion 32, playing a blocking role, thereby realizing the limiting of the protrusion 32 in the horizontal direction, thereby improving the stability of the connection between the rotating member 11 and the bayonet member 3.

[0027] As a possible implementation of this solution, preferably, Figure 2 As shown, the top shape of the pin 4 is set to be hemispherical in cross section; by setting the hemispherical top of the pin 4, when the protrusion 32 squeezes the pin 4, the friction between the contact surface between the pin 4 and the bump portion is reduced, which is beneficial to improve the smoothness of the pin 4 on the bottom surface of the protrusion 32, and reduce the scratches on the bottom surface of the protrusion 32 caused by the pin 4, thereby increasing the service life of the protrusion 32.

[0028] As a possible implementation of this solution, preferably, Figure 1 As shown, four notch portions 2 are provided on the rotating member 11, and the spacing between adjacent notch portions 2 is the same; the four notch portions 2 are distributed at four corners on the rotating member 11, and the adjacent notch portions 2 are spaced at the same distance, and the force is evenly distributed, which further improves the stability of the connection between the rotating member 11 and the bayonet member 3, and can also reduce the cost of processing and producing the rotating member 11.

[0029] As a possible implementation of this solution, preferably, Figure 2 As shown, the bottom height of the notch portion 2 is lower than the bottom height of the No. 1 groove; the end of the protrusion 32 is made of hard plastic or elastic steel and other materials, so that the end of the protrusion 32 has a certain flexibility, so that the end of the protrusion portion moves along the notch portion 2 to the No. 1 groove and can bend. The No. 1 groove has a blocking effect on the end of the protrusion 32, so that the No. 1 groove can also have a positioning effect on the protrusion 32 in the horizontal direction, which is convenient for improving the connection strength between the bayonet member 3 and the rotating member 11.

[0030] As a possible implementation of this solution, preferably, Figure 3-4 As shown, the bayonet member 3 is provided with a mounting device, which is used to assemble various light shaping accessories; the mounting device is arranged on the side of the protrusion 32 away from the rotating member 11, and different light shaping accessories are mounted on the bayonet member 3 through the mounting device. The bayonet member 3 has different types to achieve different uses; Figure 4 As shown, for example, the soft light ball light shaping accessory, its mounting device includes a protrusion on the soft light ball cover and a clamping block on the bayonet member 3, the two protrusions are mutually staggered, and then the soft light cover is rotated to make the protrusion clamped inside the clamping block, so that the soft light ball cover is mounted on the bayonet member 3; Figure 5 As shown, for example, a one-way baffle light shaping accessory, the mounting device includes a support frame and a baffle, the support frame can rotate on the top of the bayonet member 3, and the baffle is inserted into the support frame; Figure 6 As shown, for example, a four-page baffle light shaping accessory, support frames are arranged around the bayonet member 3, each support frame is provided with a light blocking sheet, and the bayonet member 3 is also provided with a mounting groove, which is used to install optional accessories such as honeycomb sheets or color sheets; thereby improving the practicality and applicability of the bayonet member 3.
