Clamping groove structure of rotatable spotlight

Abstract

The utility model discloses a clamping groove structure of a rotatable spotlight. The clamping groove structure is used for solving the problems that in a traditional installation mode, alignment is tedious, and loosening is prone to occurring. Comprising a base and a lamp holder, two pairs of wide-edge clamping grooves and narrow-edge clamping grooves which are diagonally distributed are formed in the inner wall of an annular mounting part on the back face of the base, and the lamp holder is correspondingly provided with a wide-edge carrying table and a narrow-edge carrying table. During installation, the wide-edge carrying table and the wide-edge clamping groove are aligned and then vertically inserted, the lamp holder is rotated by 90 degrees, the wide-edge carrying table is clamped to the surface of the installation boss due to the fact that the width of the wide-edge carrying table is larger than that of an expansion opening of the narrow-edge clamping groove, the wide-edge carrying table cannot retreat from the shallow-depth wide-edge clamping groove after rotation, and the narrow-edge carrying table is embedded through the deep groove to maintain vertical stability. According to the scheme, through combination of asymmetric clamping groove alignment and depth difference, 'push-in-rotation 'two-step tool-free installation is achieved, repeated adjustment actions of traditional symmetric clamping grooves are eliminated, two-way mechanical limiting (transverse anti-disengagement locking and vertical supporting) is formed after rotation, and the ceiling reflector lamp is suitable for ceiling reflector lamp scenes needing to be frequently detached and replaced.

Description

Technical Field

[0001] This utility model relates to the field of lighting equipment, and in particular to a slot structure for a rotatable spotlight. Background Technology

[0002] Recessed ceiling lights, due to their need to be embedded inside the ceiling, face limited installation space and restricted visibility. Existing installation structures generally suffer from the following problems:

[0003] 1. Cumbersome alignment: Traditional evenly distributed slots require aligning multiple points simultaneously during installation. Operators need to repeatedly adjust the angle of the lamp, which can easily lead to incomplete insertion of the slots due to errors.

[0004] 2. Insufficient locking force: The snap-on structure relies on friction or elastic deformation for fixation. After installation, the angle of the lamp can be adjusted by rotating it, which may cause the snap to loosen and pose a risk of falling off.

[0005] 3. Inconvenient disassembly: Some embedded structures require tools to disassemble, which may scratch the ceiling surface during maintenance. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the slot structure of the rotatable spotlight 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.

[0022] 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.

[0023] 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.

[0024] Please see Figures 1 to 4 The present invention discloses a slot structure for a rotatable spotlight, comprising a base (1) and a lamp holder (2); the back of the base (1) is provided with an annular mounting portion (11), and the inner wall of the mounting portion (11) is provided with two pairs of diagonally distributed mounting bosses (12) along the circumferential direction, wherein in each pair of mounting bosses (12), one pair is a wide-side slot (12a) and the other pair is a narrow-side slot (12b); the side wall of the lamp holder (2) is provided with two pairs of diagonally distributed... The card (21) has a mounting platform (22) at the end of each pair of card (21). One pair of card has a wide-side mounting platform (22a) and the other pair has a narrow-side mounting platform (22b). The width of the wide-side mounting platform (22a) is adapted to the width of the wide-side card slot (12a), and the width of the narrow-side mounting platform (22b) is adapted to the width of the narrow-side card slot (12b). The depth of the wide-side card slot (12a) is less than that of the narrow-side card slot (12b).

[0025] During installation, first install the base (1) into the ceiling, then align the wide side mounting platform (22a) with the wide side slot (12a) and the narrow side mounting platform (22b) with the narrow side slot (12b). After vertically pushing it in, rotate it 90° clockwise. Because the width of the wide side mounting platform (22a) is greater than that of the narrow side slot (12b), it is horizontally engaged with the surface of the mounting boss (12). At the same time, the shallow depth of the wide side slot (12a) prevents the wide side mounting platform (22a) from reversing and finally locks it through mechanical limit.

[0026] Similarly, when disassembling, when it is necessary to remove the lamp holder (2), rotate the lamp holder (2) counterclockwise to the initial installation angle (90° reset). At this time, the wide-side mounting platform (22a) is aligned with the opening position of the wide-side slot (12a), and the narrow-side mounting platform (22b) is simultaneously aligned with the narrow-side slot (12b). Since the wide-side slot (12a) is shallow, the user only needs to pull the lamp holder (2) vertically downwards, and the wide-side mounting platform (22a) will exit from the wide-side slot (12a), and the narrow-side mounting platform (22b) will disengage from the narrow-side slot (12b). During the rotation reset process, the wide-side mounting platform (22a) and the narrow-side slot (12b) automatically separate due to the width difference, releasing the lateral lock, and the lamp holder (2) can be removed smoothly without the need for tools. Through the difference in the depth of the slots and the irregular shape, this structure can be quickly separated by applying only vertical pulling force during disassembly, avoiding the wear of parts caused by prying required by traditional snap-on disassembly.

[0027] Please see Figures 1 to 4 In another embodiment, each pair of mounting bosses (12) is provided with baffles (13) on both sides. The baffles (13) are arranged perpendicular to the end face of the mounting bosses (12). When the lamp holder (2) rotates, the locking piece (21) moves along the inner side of the baffles (13). When it rotates to 90°, the baffles (13) on both sides prevent the locking piece (21) from continuing to rotate. Beneficial effect: Limits the rotation angle and avoids locking failure due to excessive rotation and displacement.

[0028] Please see Figures 1 to 4 In another embodiment, the lamp holder (2) is made of metal. The clip (21) of the metal lamp holder (2) and the mounting platform (22) are integrally formed by stamping, which makes it less prone to deformation under high temperature or high load conditions. Beneficial effects: enhances structural strength and heat dissipation performance, improves service life, and at the same time makes the lamp holder (2) heavier, which is supported by its own weight on the base (1).

[0029] Please see Figures 1 to 4 In another embodiment, the mounting boss (12) extends toward the center of the base (1), making the slot visible from the front of the base (1). The extended portion of the mounting boss (12) passes through the through hole of the base (1), allowing the user to directly observe the opening positions of the wide-side slot (12a) and the narrow-side slot (12b) from the front view of the base (1). Beneficial effect: Eliminates blind spots in the installation view, facilitating rapid alignment.

[0030] Please see Figures 1 to 4In another embodiment, the depth of the wide-side slot (12a) is 1-2 mm, and the depth of the narrow-side slot (12b) is 3-5 mm. The shallow depth of the wide-side slot (12a) allows it to accommodate the wide-side mounting platform (22a) only when inserted vertically, preventing it from retracting after rotation; the deep depth of the narrow-side slot (12b) ensures that the narrow-side mounting platform (22b) forms a stable support after being fully embedded in the slot. Beneficial effect: Bidirectional anti-loosening locking is achieved through the combination of shallow and deep slots.

[0031] Please see Figures 1 to 4 In another embodiment, the horizontal extension length of the mounting platform (22) is 1.2-1.5 times the width of the slot. If the width of the wide-side slot (12a) is 6mm, the horizontal extension length of the wide-side mounting platform (22a) is 7-9mm, and the portion (1-3mm) of the mounting platform (22) extending beyond the slot after rotation overlaps the surface of the mounting boss (12). Beneficial effect: Increases the contact area and prevents the lamp head from shaking.

[0032] Please see Figures 1 to 4 In another embodiment, the lamp holder (2) is circular or square in shape. The clips (21) of the circular lamp holder (2) are evenly distributed circumferentially; the clips (21) of the square lamp holder (2) are distributed at the joints of adjacent sides. Beneficial effect: Adapts to the appearance requirements of different installation scenarios.

[0033] Please see Figures 1 to 4 In another embodiment, the width ratio of the wide-side slot (12a) to the narrow-side slot (12b) is 1.5-2:1. When the width of the wide-side slot (12a) is 9mm, the width of the narrow-side slot (12b) is 4.5-6mm. The narrow-side mounting platform (22b) can pass through the wide-side slot (12a), but the wide-side mounting platform (22a) cannot enter the narrow-side slot (12b). This proportional design forces a distinction in installation direction, avoiding misinstallation.

[0034] 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.
