Description

Technical Field

[0001] This utility model relates to the technical field of window sill lamp fixing base, specifically a rotatable window sill lamp fixing base. Background Technology

[0002] As an important auxiliary lighting and ambiance creation tool, window sill lamps are widely used in residential, commercial and public spaces. In order to meet diverse lighting needs, a large number of adjustable lamps have appeared on the market, and the design of their fixed bases has also become increasingly diversified. Usually, hinges, pivots and other structures are used to achieve the angle adjustment of the lamps within a certain range in order to achieve more flexible lighting effects.

[0003] However, most existing window sill lamp mounting bases suffer from limited adjustment options or unreliable locking mechanisms. This is especially problematic when faced with complex installation environments where the window sill itself has an angle. A single adjustment mechanism often cannot simultaneously correct for installation reference deviations and achieve precise control of the lighting angle, causing the light projection to deviate from the intended area and significantly reducing its practicality. Furthermore, many adjustment structures are prone to loosening after locking due to external vibrations or material fatigue, failing to guarantee stable lighting performance over a long period and affecting the user experience. Therefore, a rotatable window sill lamp mounting base is needed to address these shortcomings. Utility Model Content

[0004] Technical problems to be solved Existing window sill lamp mounting bases suffer from insufficient adjustment dimensions, inability to precisely control light, and poor stability after locking in complex installation environments such as tilted window sills.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: a rotatable windowsill lamp fixing base, comprising: The first base is long and narrow, used to fix it to the windowsill; Base 2 is rotatably connected to base 1 via pivot 1; The lamp body is rotatably mounted on the inner side of the base two; Limiting structure one is disposed between the base one and the base two, and is used to control and lock the rotation angle of the base two; The second limiting structure is disposed between the second base and the lamp body, and is used to control and lock the rotation angle of the lamp body.

[0006] Furthermore, the second base is U-shaped and includes two opposing vertical arms; One of the vertical arms has a receiving groove 1, and the other vertical arm has a receiving groove 2; One end of the lamp body is movably connected to the receiving groove 1 via a rotating shaft 2, and the other end is movably connected to the receiving groove 2 via a rotating shaft 3.

[0007] Furthermore, the limiting structure is a one-way ratchet mechanism, which includes: The ratchet is fixed on the first rotating shaft; The pawl is movably connected to the interior of the base one via a pivot and engages with the ratchet in one direction only; The first elastic element is used to ensure that the pawl always tends to engage with the ratchet.

[0008] Furthermore, the elastic element is a return spring, one end of which is fixed to the back side of the pawl, and the other end is fixed inside the base.

[0009] Furthermore, the second limiting structure is a meshing tooth locking mechanism, which includes: The first tooth is fixedly installed in the first receiving groove and is coaxially arranged with the second rotating shaft. The second tooth is fixed to the end of the second rotating shaft and meshes with the first tooth; The unlocking component is used to drive the second tooth to move axially, so that it disengages from the first tooth.

[0010] Furthermore, the unlocking component includes: The knob is fixed to the end of the second rotating shaft; The second elastic element is disposed in the second receiving groove and is used to apply an axial force toward the first tooth to the lamp body; By pressing the knob, the elastic force of the second elastic element can be overcome, causing the lamp body to move axially within the first and second receiving grooves, thereby disengaging the second tooth from the first tooth.

[0011] Furthermore, the second elastic element is a return spring, a retaining ring is sleeved on the third rotating shaft, and the retaining ring is movably engaged with the second receiving groove. One end of the return spring is fixed on the retaining ring, and the other end is fixed to the bottom of the second receiving groove.

[0012] Furthermore, mounting plates with mounting holes are fixedly connected around the base.

[0013] Compared with existing technologies, this rotatable window sill lamp fixing base has the following advantages: I. This utility model achieves horizontal rotation angle adjustment and one-way locking of base two by setting a one-way ratchet mechanism composed of ratchet and pawl between base one and base two. The user only needs to rotate base two to change the horizontal illumination direction of the lamp. It will automatically lock after being released, making the operation more convenient and ensuring the stability and reliability of horizontal angle adjustment.

[0014] Second, this utility model effectively solves the problem of tilted or uneven windowsill mounting surfaces through a dual structural design of horizontal rotation adjustment and pitch angle adjustment. Users can first make coarse adjustments by horizontal rotation to offset the tilt deviation of the mounting surface, and then make fine adjustments by pitch adjustment to align with the target area, thereby transforming irregular windowsills into a stable, efficient and angle-controllable ideal lighting platform, greatly improving the adaptability and practicality of the product.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-5 As shown, this utility model provides a technical solution: a rotatable window sill lamp fixing base. The base can realize the angle adjustment of the lamp in both horizontal and vertical dimensions, and can be stably locked after adjustment. The fixing base mainly consists of a long strip-shaped base 1 and a base 2 that can rotate relative to it. The base 1 serves as the mounting base of the entire device, and multiple mounting pieces 9 with mounting holes extend from its perimeter. In actual installation, screws can be used to pass through these mounting holes to firmly fix the base 1 to the window sill, wall or other flat surface.

[0019] like Figure 1 , Figure 2 and Figure 5 As shown, base 2 is connected to base 1 via a horizontal pivot 3, allowing it to rotate horizontally around pivot 3. To control and lock the rotation angle of base 2, a limiting structure 5 is installed inside base 1. This structure is a one-way ratchet 501 mechanism, in which a ratchet 501 is firmly fixed on pivot 3 and rotates with base 2. Inside base 1, a pawl 502 is also movably installed via a small pivot. Under the elastic force of the return spring (elastic element 503), the tip of the pawl 502 is always engaged in the tooth groove of the ratchet 501, forming a one-way engagement. When the horizontal angle needs to be adjusted, base 2 is rotated forcefully, and the tooth surface of ratchet 501 pushes the pawl 502 away, allowing base 2 to rotate smoothly. Once the force is stopped, the pawl 502 immediately engages the ratchet 501 under the action of the spring, preventing it from rotating in the opposite direction, thereby precisely locking base 2 in the current position.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the base 2 is U-shaped and has two opposing vertical arms. The lamp body 4 is installed between these two vertical arms. In order to adjust the pitch angle of the lamp body 4, one of the vertical arms has a receiving groove 7 and the other vertical arm has a corresponding receiving groove 8. One end of the lamp body 4 is movably connected to the receiving groove 7 through a pivot 2, and the other end is movably connected to the receiving groove 8 through a pivot 3.

[0021] To lock the pitch angle of the lamp body 4, a limiting structure 2 6 is set between the base 2 and the lamp body 4. It is essentially a set of meshing tooth locking mechanisms. A ring-shaped tooth 601 is fixed in the receiving groove 7. At the end of the rotating shaft 2, a tooth 602 that matches the tooth 601 is fixed. In the natural state, the tooth 601 and the tooth 602 are tightly meshed, thereby restricting the rotation of the lamp body 4.

[0022] For easy adjustment, an unlocking component is also provided. A knob 603 is fixed to the outer end of the second rotating shaft. The diameter of the knob 603 is adapted to the inner diameter of the second receiving groove 8, making it convenient for users to operate. Inside the second receiving groove 8, a return spring is provided as an elastic element 604. A retaining ring 605 is fitted on the third rotating shaft. One end of the return spring is fixed to this retaining ring 605, and the other end abuts against the bottom of the second receiving groove 8. This return spring always applies a pushing force to the lamp body 4 toward the first receiving groove 7, ensuring that the first gear 601 and the second gear 602 remain engaged.

[0023] When the pitch angle of the lamp body 4 needs to be adjusted, the user simply presses the knob 603 towards the receiving slot 2 8. This pressure overcomes the spring force of the return spring, pushing the entire lamp body 4 to make a slight axial movement within the two receiving slots, causing the originally engaged teeth 2 602 to disengage from teeth 1 601. At this point, the lamp body 4 can rotate freely. After adjusting to the ideal angle, the knob 603 is released. Under the pushing force of the return spring, the lamp body 4 will be pushed back to its original position, and teeth 1 601 and teeth 2 602 will re-engage, firmly locking the lamp body 4 at the new angle.

[0024] In this embodiment, the rotatable windowsill lamp fixing base is designed to solve the problem of complex windowsill installation environments. In practical applications, especially in modern buildings or old houses, the installation surface of the windowsill is often not an ideal horizontal plane, but has a preset tilt angle for drainage or design needs. If a traditional fixed lamp holder is used, the lamp body 4 will inevitably tilt with the windowsill, causing the beam to shift upward or downward, failing to effectively illuminate the predetermined area, resulting in wasted light energy and inconvenience. First, after the user fixes the base 1 on the tilted windowsill, the horizontal rotation mechanism (i.e., the limiting structure 5) between the base 1 and the base 2 can be used. Coarse adjustment is performed by rotating base 2 to offset the initial angle deviation caused by the tilt of the windowsill, so that the basic orientation of the lamp body 4 returns to the horizontal baseline facing the room. On this basis, the user can then use the limiting structure 6 to finely adjust the pitch angle of the lamp body 4 until the beam accurately covers the target area, such as a desk, sofa or painting on the wall. After adjustment, the two limiting structures are locked independently to ensure that the lamp can maintain the preset illumination angle for a long time, even in an environment where there may be slight vibrations, such as a windowsill. This transforms a functionally limited tilted windowsill into a stable, efficient and angle-controllable ideal lighting point.
