[0003] This utility model relates to the field of lighting technology, and in particular to a lighting angle adjustment structure. Background Technology

[0004] After installation, lighting fixtures sometimes need to be adjusted according to actual needs, such as recessed spotlights. For track lights, a connecting joint is usually used to connect the fixture and the driver. The rotation of the fixture is controlled by adjusting the tightness of the joint. However, this method makes it difficult to control the rotation angle of the fixture. If the fixture is repeatedly rotated in one direction, the connection between the fixture and the joint may become loose, resulting in unstable installation. Summary of the Invention

[0005] This utility model addresses the problems of existing technology by providing a lamp angle adjustment structure. It controls the rotation angle of the lamp connector by limiting the rotation of the shim through the rotation limit hole, thereby controlling the rotation angle of the lamp and preventing the lamp from rotating in the same direction. This ensures the installation stability of the lamp while allowing it to rotate.

[0007] Preferably, the washer has a fixing hole, and the outer periphery of the external driver has a protrusion, which is fitted into the fixing hole.

[0008] Preferably, there are two rotation limiting holes, which are symmetrically arranged with the axis of the gasket as the axis of symmetry.

[0009] Preferably, the rotating limiting hole is arc-shaped.

[0010] Preferably, both ends of the rotation limiting hole are provided with locking blocks, and when the protrusion moves, it first engages with the locking blocks and then moves to the end of the rotation limiting hole.

[0011] Preferably, the tooth segment has two limiting surfaces, and the shape of the second through hole is adapted to the tooth segment.

[0012] Preferably, the lamp connector includes a connecting block and a fixing block. The fixing block has an assembly hole on its outer periphery, the connecting block has an assembly block that is assembled into the assembly hole, and the second through hole is located on the fixing block.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a lamp angle adjustment structure in which the lamp is installed on the lamp connector and the gasket is fixed to the lamp connector. The lamp connector can drive the gasket to rotate.

Detailed Implementation

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0022] This embodiment provides a lamp angle adjustment structure, as shown in Figures 1 to 5, including a threaded joint 31, a washer 32, a gasket 33, a lamp connector, and a locking member 311. One end of the threaded joint 31 is mounted on an external driver, the washer 32 is fixed to the external driver, the lamp connector is provided with a limiting groove 36, the gasket 33 is assembled into the limiting groove 36, the washer 32 is located above the gasket 33, the washer 32 is provided with a protrusion 37, and the gasket 33 has a rotating opening. The limiting hole 38 is provided, and the protruding post 37 is located in the rotating limiting hole 38 and can move in the rotating limiting hole 38; the washer 32 has a first through hole 39 in the middle, and the lamp connector has a second through hole 310 in the middle; the other end of the threaded joint 31 passes through the first through hole 39 and the second through hole 310 in sequence, and the threaded joint 31 is locked to the lamp connector by the locking member 311; when the lamp connector rotates, it drives the threaded joint 31 to rotate.

[0023] Specifically, washer 32 is connected to the driver of the lamp to prevent it from rotating. The lamp connector is connected to the lamp and can be rotated by rotating the lamp. The rotation of the lamp connector causes the washer 33 to rotate, and the rotation limiting hole 38 also rotates accordingly. When the protrusion 37 of washer 32 is engaged with the end of the rotation limiting hole 38, the lamp can no longer rotate, thus limiting the rotation of the lamp. Therefore, as shown in Figure 4, the lamp can rotate clockwise or counterclockwise under the restriction 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 achieved. The size of the rotation limiting hole 38 can be set according to the actual situation, and this embodiment does not impose any restrictions.

[0024] As shown in Figure 2, the shape of the toothed joint 31 includes a circular toothed joint 31 cap, which is installed in the driver. The portion of the toothed joint 31 located in the first through hole 39 and the second through hole 310 has the shape shown in Figure 5, with two limiting surfaces 315, so that the toothed joint 31 can be rotated when the lamp connector rotates. The first through hole 39 does not restrict the rotation of the toothed joint 31, thus avoiding affecting the fixation of the washer 32.

[0025] Figure 3 shows the structure of washer 32. Washer 32 is provided with a slot for embedding an external driver, and 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 protruding post 37 fixed. In this way, when the washer 33 rotates, the protruding post 37 does not rotate, ensuring that the relative position of the protruding post 37 changes within the limiting range of the rotation limiting hole 38, thus limiting the rotation angle of the lamp.

[0026] Figures 3 and 4 show the structure of the gasket 33, which has two arc-shaped rotation limiting holes 38, 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.

[0027] Figures 2 and 3 show the structure of the lamp connector. The lamp connector 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.

[0028] 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.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
