[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the adjustable angle spotlight structure of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0024] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1 to 6 A novel adjustable angle spotlight structure according to an embodiment of the present invention includes a lamp housing (1) and a base (2); the bottom side of the lamp housing (1) is evenly provided with a plurality of through holes (11), and the bottom inner wall of the lamp housing (1) is provided with a sliding groove (12) along the circumferential direction, the sliding groove (12) penetrating the through holes (11); a lamp bead (21) is fixedly provided on the top end face of the base (2), and the top side of the base (2) is evenly provided with locking posts (22) matching the shape of the through holes (11); The lamp bead component (21) has a first baffle (211) extending outward from its side, and the lamp housing (1) has a second baffle (13) extending inward from its inner wall. The first baffle (211) and the second baffle (13) form a closed space (14), and a spring component (3) is provided in the closed space (14). The locking pin (22) can be disengaged from the through hole (11) and enter the slide groove (12) by pressing the base (2). The spring component (3) provides a restoring force so that the locking pin (22) can be re-engaged into the through hole (11).

[0027] The through hole (11) and the slide groove (12) of the lamp housing (1) constitute the moving path of the locking post (22): the through hole (11) is the fixed position of the locking post (22), and the slide groove (12) is the continuous transition path during rotation.

[0028] When the base (2) is pressed, the lamp bead (21) moves upward along with the base (2), the locking pin (22) comes out from the through hole (11) and enters the slide groove (12), and the first stop (211) compresses the spring (3) to store energy.

[0029] The rotating base (2) drives the LED bead component (21) and the locking pin (22) to slide along the slide groove (12). When the locking pin (22) is aligned with the target through hole (11), the spring component (3) pushes the locking pin (22) to re-embed into the through hole (11), producing a "click" sound and a tactile feedback. Each gear has clear mechanical feedback during the adjustment process, avoiding angle deviation; the enclosed space design of the spring component (3) prevents dust intrusion and jamming.

[0030] Please see Figures 1 to 6 In another embodiment, the outer wall of the lamp housing (1) is an arc-shaped curved surface, and the lamp housing (4) is also provided with an arc-shaped groove (41) on the inner wall of the lamp housing (1) that matches the shape of the outer wall of the lamp housing (1). The lamp housing (1) can rotate around the axis of the arc-shaped groove (41) to adjust the angle.

[0031] The outer wall of the lamp housing (1) is arc-shaped: it adopts an arc-shaped curved surface design (e.g., an arc with a central angle of 60°), and its curvature matches the arc-shaped groove (41) of the lamp assembly (4) to form a sliding curved surface pair.

[0032] The lamp assembly (4) has an arc-shaped groove (41): The inner wall of the lamp assembly (4) has a groove (41) that is consistent with the curvature of the outer wall of the lamp housing (1), so that the lamp housing (1) can be adjusted in pitch along the axis of the groove (41) (such as the horizontal axis).

[0033] Adjustment process:

[0034] 1. After the lamp housing (1) is embedded in the groove (41) of the lamp kit (4), the locking post (22) is released by pressing the base (2) (that is, the locking post is released from the through hole and enters the slide by pressing).

[0035] 2. The user holds the lamp housing (1) and rotates it along the groove (41) to change the pitch angle of the spotlight (e.g., 0°~45° range).

[0036] 3. After releasing the base (2), the locking pin (22) and the through hole (11) are locked again.

[0037] The curved lamp housing (1) works in conjunction with the above-mentioned recessed lamp kit (4) to achieve a wide range of pitch angle adjustment (traditional spotlights usually only support horizontal rotation), and the sliding pair structure has no gap wobbling.

[0038] Please see Figures 1 to 6 In another embodiment, an annular locking member (5) is also included, which is threaded to the bottom of the lamp assembly (4). The diameter of the annular locking member (5) is smaller than the maximum diameter of the lamp housing (1) to limit the displacement of the lamp housing (1).

[0039] The annular locking member (5) matches the external thread at the bottom of the lamp assembly (4) via its internal thread. Rotating the locking member (5) allows it to move up and down along the lamp assembly (4).

[0040] When the locking part (5) is tightened, its top inner edge abuts against the bottom outer wall of the lamp housing (1). Because the inner diameter of the locking part (5) is slightly smaller than the maximum outer diameter of the lamp housing (1), a circumferential pressure is formed to constrain the displacement of the lamp housing (1). The gap between the lamp housing (1) and the lamp assembly (4) is eliminated by thread pre-tightening to prevent vibration from causing angular displacement.

[0041] Please see Figures 1 to 6 In another embodiment, the spring (3) is a compression spring, with one end abutting against the first stop (211) and the other end abutting against the second stop (13).

[0042] After the compression spring is installed in the closed space (14), the two ends are pressed against the first stop (211) and the second stop (13) respectively. The axial compression direction is consistent with the movement direction of the locking pin (22) to ensure the efficiency of force transmission.

[0043] Please see Figures 1 to 6 In another embodiment, the inner wall of the annular locking member (5) is provided with anti-slip teeth and a rubber ring.

[0044] The teeth (such as triangular sawtooth pattern) on the inner wall of the locking part (5) increase the friction with the lamp housing (1). Even if the thread comes loose due to vibration, the teeth can still temporarily clamp the lamp housing (1), and the rubber ring can enhance its sealing performance.

[0045] Please see Figures 1 to 6 In another embodiment, the through hole (11) is a rectangular hole or a circular hole, and the cross-section of the locking post (22) matches the through hole (11) and the groove (12).

[0046] Design options:

[0047] Rectangular hole: suitable for injection molded lamp housing (1), the rectangular sidewall can restrict the circumferential rotation of the locking post (22);

[0048] Circular holes: suitable for metal stamping processes, reducing processing difficulty.

[0049] Please see Figures 1 to 8 In another embodiment, the lamp bead component (21) includes an optical lens (212) and a circular retaining ring (213). The optical lens (212) is fixedly mounted on the base (2), and the circular retaining ring (213) is sleeved on the optical lens (212). The inner side of the lamp housing (1) is also provided with three vertically arranged sliding grooves (12), which are connected by a straight channel (6). The base (2) and the lamp housing (1) are both provided with marking portions (7) on their sides.

[0050] During installation, after the optical lens (212) is centered, the circular pressure ring (213) provides circumferential locking force to prevent the lens from shifting. The function of the slide groove (12) is to accommodate optical lenses (212) of different sizes. For example, when a larger lens is installed into the lamp housing, the two side protrusions of the optical lens (212) are embedded in the upper ring channel. The smaller optical lens is inserted into the bottom slide groove (12), and the medium-sized optical lens (212) is inserted into the middle slide groove (12). The lamp housing (1) has multiple markings, which correspond to the through hole (11) and the straight channel (6) of the base (2). When the markings (7) on the base (2) are rotated to the markings (7) corresponding to the through hole (11), the angle of the lamp beam can be adjusted. When the markings (7) on the base (2) are rotated to the markings (7) corresponding to the straight channel (6), the two side protrusions of the optical lens (212) enter the straight channel (6), allowing the optical lens (212) to detach from the lamp housing (1).

[0051] 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 modifications or alterations 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 alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
