DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of those skilled in the art, the utility model is further described below in combination with examples and drawings, and the content mentioned in the implementation manner is not a limitation of the utility model. The utility model is described in detail below in combination with drawings.

[0021] The utility model provides a kind of lamp angle adjusting structures provided in the embodiment, as shown in Figures 1 to 5, including tooth 31, gasket 32, gasket 33, lamp connecting piece and locking piece 311, one end of the tooth 31 is installed in the external driver, the gasket 32 is fixed to the external driver, the lamp connecting piece is provided with a limiting groove 36, the gasket 33 is assembled in the limiting groove 36, the gasket 32 is located above the gasket 33, the gasket 32 is provided with a convex column 37, the gasket 33 is provided with a rotation limiting hole 38, the convex column 37 is located in the rotation limiting hole 38, and the convex column 37 can move in the rotation limiting hole 38; The middle part of the gasket 32 is provided with a first via hole 39, the middle part of the lamp connecting piece is provided with a second via hole 310, the other end of the tooth 31 is sequentially provided with the first via hole 39 and the second via hole 310, and the tooth 31 and the lamp connecting piece are locked by the locking piece 311; The lamp connecting piece rotates to drive the tooth 31 to rotate.

[0022] Specifically, the gasket 32 is connected with the driver of the lamp to make the gasket 32 unable to rotate, the lamp connecting piece is connected with the lamp, the lamp connecting piece can be driven to rotate by rotating the lamp, the lamp connecting piece rotates to drive the gasket 33 to rotate, and then the rotation limiting hole 38 also rotates, when the convex column 37 of the gasket 32 is clamped to the end of the rotation limiting hole 38, the lamp cannot rotate again, the rotation of the lamp is limited, therefore, as shown in Figure 4 , the lamp can rotate clockwise or counterclockwise under the limitation of the rotation limiting hole 38, the angle of rotation is determined by the rotation limiting hole 38, as shown in Figure 4 , when the length of the rotation limiting hole 38 is longer, a larger angle of rotation can be realized, the size of the rotation limiting hole 38 can be set according to actual conditions, and the embodiment is not limited.

[0023] As shown in Figure 2 , the shape of the tooth 31, which includes a circular tooth 31 cap, is installed in the driver, the part of the tooth 31 in the first via hole 39 and the second via hole 310 has a shape as shown in Figure 5 , has two limiting surfaces 315, so that the tooth 31 can be driven to rotate when the lamp connecting piece rotates, the first via hole 39 does not limit the rotation of the tooth 31, avoiding affecting the fixation of the gasket 32.

[0024] As shown in Figure 3The structure of washer 32 is shown. Washer 32 is provided with a slot for embedding an external driver. The outer periphery of the external driver fits against the slot wall. The external driver is also provided with a protrusion 313, which is inserted into the fixing hole 312 of washer 32 to achieve positioning between the two and maintain the fixation between washer 32 and driver, thereby keeping the protrusion 37 fixed. In this way, when washer 33 rotates, protrusion 37 does not rotate, ensuring that the relative position of protrusion 37 within the limiting range of rotation limiting hole 38 changes, thus limiting the rotation angle of the lamp.

[0025] like Figure 3 and Figure 4 The diagram shows the structure of the gasket 33, which has two rotation limiting holes 38, both arc-shaped, symmetrically arranged about the central axis of the gasket 33. To allow the user to determine whether the protrusion 37 is located at the end of the rotation limiting hole 38, this embodiment provides locking blocks 314 at both ends of the rotation limiting hole 38. Since the protrusion 37 is cylindrical, it can reach the end of the rotation limiting hole 38 through the locking blocks 314. When the user rotates the lamp, they will feel the locking contact between the protrusion 37 and the locking blocks 314, indicating that the protrusion 37 is at the end of the rotation limiting hole 38. This means the lamp's rotation has reached the limited angle and cannot be continued, or the user can choose to rotate in the opposite direction. The locking blocks 314 facilitate the user's understanding of the lamp's rotation position.

[0026] like Figure 2 and Figure 3 The diagram shows the structure of the lamp connector, which includes a connecting block 34 and a fixing block 35. The fixing block 35 has an assembly hole 316 on its outer periphery. The connecting block 34 is provided with an assembly block 317 that is assembled into the assembly hole 316. The second through hole 310 is located in the fixing block 35. After the threaded joint 31 passes through the second through hole 310, the threaded joint 31 is locked to the lamp connector by the locking member 311. The tightness of the lamp rotation can be adjusted by adjusting the locking degree of the locking member 311, which provides high flexibility.

[0027] This embodiment uses the fit between washer 32 and shim 33 to restrict the rotation of the lamp, thereby avoiding unstable installation of the lamp due to repeated rotation, making it more practical.

[0028] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed as above in the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiment with equivalent changes is equivalent to the above embodiment. Any simple modification, equivalent change and modification of the above embodiment according to the present application technical solution are within the scope of the present application technical solution.
