Description

Technical Field

[0001] This utility model belongs to the field of lighting fixture technology, specifically, it relates to an adjustable lighting fixture. Background Technology

[0002] Lighting fixtures are indispensable electrical devices in daily life and work. Common types include ceiling lights, chandeliers, and table lamps, which are widely used in various spaces such as homes and offices to provide basic lighting support for users. In existing lighting technology, power supply generally relies on the connection between a power cord and a power socket. This involves inserting the plug at the end of the power cord into an external socket to input electrical energy and turn on the light. However, when the power cord of a light fixture is excessively long, such as when the fixture is installed close to a power socket, the excess cord can easily fall to the ground. This not only affects the cleanliness and aesthetics of the surrounding environment but also poses a potential safety hazard. People walking on the ground may trip over the cord, causing the fixture to wobble and become unstable, or even fall from its installation location or surface, damaging the fixture or causing injury.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adjustable lighting fixture, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: An adjustable lighting fixture, comprising: The base has a cavity inside; An adjustable support rod is rotatably fitted onto the base, and a rotating block is rotatably fitted onto the upper end of the adjustable support rod. The lighting fixture body is rotatably connected to the rotating block. The winding assembly includes a take-up roller that is rotatably engaged in a cavity via a torsion spring. Both ends of the take-up roller are rotatably engaged with ratchet wheels. The opposite inner sides of the cavity are rotatably engaged with anti-return pawls via torsion springs. The anti-return pawls engage with the ratchet wheels. A lever is fixed to one side of the anti-return pawl, and one end of the lever extends to the outside of the base. The power cord has one end wound around the take-up roller.

[0006] Optionally, the base has multiple suction cups on its underside.

[0007] Optionally, a storage slot is provided on the upper side of the base, which cooperates with the lamp body and the adjustable support rod.

[0008] Optionally, the adjustable support rod includes multiple cylinders that are sequentially nested together, and the inner wall of the cylinder is provided with friction damping. One of the cylinders at one end of the adjustable support rod is rotatably fitted into the storage groove, and a positioning element is elastically fitted inside.

[0009] Optionally, the positioning component includes a positioning rod that is elastically fitted inside the cylinder and a sliding rod that is slidably fitted on one side of the cylinder. The sliding rod is fixedly connected to the positioning rod, and the ends of both the positioning rod and the sliding rod extend to the outside of the cylinder. A positioning groove is provided at the bottom of the storage slot, and the positioning groove cooperates with the positioning rod.

[0010] Optionally, spherical grooves are provided on the relatively inner sides of the cylinder, and elastic beads are elastically fitted on the relatively outer sides of the lower part of the cylinder, with the elastic beads cooperating with the spherical grooves.

[0011] Optionally, the check pawl has a pivot in the middle, which is rotatably connected to the inside of the cavity. The check pawl has a power unit, and the lever is fixedly connected to the power unit.

[0012] Optionally, a connecting plate is fixed between the two power units, and a through hole communicating with the cavity is opened on one side of the storage slot, which cooperates with the positioning rod.

[0013] Optionally, the power cord is electrically connected to the lighting fixture, and one end of the power cord is equipped with a power plug.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: 1. The adjustable support rod, through the cooperation of multiple sequentially nested cylinders, combined with the engagement of spherical grooves and elastic ball bearings and the friction damping of the inner wall, can achieve flexible length adjustment and stable locking to adapt to different height requirements; the lighting body achieves dual angle control of horizontal rotation and tilt adjustment through the rotating block, and together with the height-adjustable support rod, it can match the lighting direction and range requirements of diverse usage scenarios. 2. The winding assembly's take-up roller, ratchet, and check pawl work together to allow the power cord to be pulled to a specified length and automatically locked, avoiding the risk of accidental contact due to excessive length. The adjustable support rod's positioning rod and the winding assembly's connecting plate form a storage linkage. When the storage support rod is rotated, the positioning rod presses against the connecting plate through the through hole, simultaneously releasing the check pawls and ratchet on both sides, triggering the take-up roller to automatically retract the cord, eliminating the need for separate operation and simplifying the storage process. Simultaneously, the lever provides an alternative solution for separate unlocking and retraction, offering greater operational flexibility. 3. Multiple suction cups on the underside of the base can adhere tightly to smooth surfaces, providing a stable foundation for the entire lamp; when the adjustable support rod is rotated to the vertical position, the positioning rod inserts into the positioning slot of the storage slot, forming a mechanical positioning to prevent the support rod from tipping over; the elastic ball bearings between the cylinders and the spherical groove work together to provide friction damping, which can lock the telescopic length to prevent it from sliding on its own. The multiple structures work together to ensure that the lamp does not shift or shake during use. 4. The storage slot on the upper side of the base can fully accommodate the adjustable support rod and the lighting body after resetting, compressing the storage volume and reducing the space occupied. After storage, the storage slot forms a physical wrap around the lighting body, which can isolate dust and avoid bumps and damage. At the same time, the winding roller stores the power cord in the cavity, preventing the cable from being exposed, aging, or tangled, thus extending the overall service life of the lamp.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Please see Figure 1-3As shown, this embodiment provides an adjustable lighting fixture, including: Base 1, with a cavity 102 inside the base 1; Adjustable support rod 2 is rotatably fitted on base 1, and a rotating block 201 is rotatably fitted on the upper end of adjustable support rod 2; Lighting lamp body 3, which is rotatably connected to rotating block 201; The winding assembly 4 includes a take-up roller 401 that is rotatably engaged in the cavity 102 via a torsion spring. Both ends of the take-up roller 401 are rotatably engaged with ratchet wheels 402. The inner sides of the cavity 102 are rotatably engaged with anti-return pawls 403 via torsion springs. The anti-return pawls 403 engage with the ratchet wheels 402. A lever 404 is fixed on one side of the anti-return pawl 403. One end of the lever 404 extends to the outside of the base 1. Power cord 5, one end of which is wound around take-up roller 401.

[0021] How to use: When using the lighting fixture, first rotate the adjustable support rod 2 to adjust it to a vertical position; then rotate the lighting body 3 to make it horizontal; then connect the power supply through the power cord 5 to start the lighting fixture. When the adjustable support rod 2 is in a vertical position, its height can be adjusted according to actual usage needs to further adapt to the usage scenario; while when the lighting body 3 is adjusted to a horizontal position, it can be rotated horizontally with the help of the rotating block 201, or the illumination angle can be changed by tilting adjustment to ensure that the lighting direction meets the user's needs. After the angle of the lamp body 3 is adjusted, the power cord 5 can be pulled to a suitable length and then connected to the socket to power the lamp. During the pulling of the power cord 5, the take-up roller 401 will rotate, and the take-up roller 401 will simultaneously drive the ratchet 402 to rotate. At this time, the inclined surface of the ratchet 402 engages with the anti-return pawl 403, which does not affect the pulling out of the power cord 5. When the power cord 5 reaches the required length, the anti-return pawl 403 and the plane of the ratchet 402 are in contact, restricting the rotation of the ratchet 402, thereby fixing the take-up roller 401 and preventing the user from accidentally touching or tripping over the excessively long power cord 5. After using the lighting fixture, first disconnect the power cord 5 from the power source, then move the lever 404. The lever 404 will cause the anti-return pawl 403 to rotate, releasing it from the engagement with the ratchet 402. At this time, the torsion spring will drive the take-up roller 401 to rotate in the opposite direction, automatically winding the power cord 5 to complete the storage of the power cord 5. Finally, rotate the lighting fixture body 3 to reset and adjust the adjustable support rod 2 to the initial position to complete the storage of the entire lighting fixture.

[0022] In this embodiment, the base 1 is provided with multiple suction cups on its lower side.

[0023] The suction cups allow the base 1 to adhere to a smooth surface, thereby improving the stability of the lighting fixture during use.

[0024] In this embodiment, a storage slot 101 is provided on the upper side of the base 1, and the storage slot 101 cooperates with the lighting body 3 and the adjustable support rod 2.

[0025] When storing the lighting fixture, after the adjustable support rod 2 is reset and the lighting body 3 is rotated to the specified angle, both can be completely embedded inside the storage slot 101. This reduces the overall volume of the lighting fixture after storage, saves space, and makes storage more convenient. At the same time, the storage slot 101 can physically enclose the lighting body 3, isolating it from external dust, bumps, and other damage, thus providing protection for the lighting body 3.

[0026] The adjustable support rod 2 in this embodiment includes multiple cylinders 202 arranged in sequence, and friction damping is provided on the inner wall of the cylinder 202. One of the cylinders 202 at one end of the adjustable support rod 2 is rotatably fitted in the storage groove 101, and a positioning member 203 is elastically fitted inside. The positioning member 203 in this embodiment includes a positioning rod 204 elastically fitted in the cylinder 202 and a sliding rod 205 slidably fitted on one side of the cylinder 202. The sliding rod 205 is fixedly connected to the positioning rod 204, and the ends of the positioning rod 204 and the sliding rod 205 both extend to the outside of the cylinder 202. A positioning groove 104 is opened at the bottom of the storage groove 101, and the positioning groove 104 cooperates with the positioning rod 204. In this embodiment, spherical grooves are opened on the relatively inner sides of the cylinders 202, and elastic beads are elastically fitted on the relatively outer sides of the lower part of the cylinder 202, and the elastic beads cooperate with the spherical grooves.

[0027] The telescopic principle of the adjustable support rod 2 is the same as that of telescopic rods in the prior art, and can be referenced from the structural logic of the folding umbrella pole: when the length needs to be adjusted, the user can directly pull the end of the cylinder 202 to extend the adjustable support rod 2; after the length is adjusted, the inner spherical groove of the cylinder 202 and the outer elastic ball engage with each other, and combined with the friction damping preset on the inner wall of the cylinder, the two work together to firmly lock the extension position of the adjustable support rod 2, ensuring that it remains stable during use and preventing it from telescopically extending or retracting on its own; In addition, the positioning rod 204 on the adjustable support rod 2 has a key positioning function: when the adjustable support rod 2 is rotated to the vertical position, the positioning rod 204 can be inserted into the positioning groove 104 of the base, and the vertical position of the adjustable support rod 2 is restricted by mechanical locking, which further ensures its stability during use and prevents it from tipping over or shifting; while the slide rod 205, which is fixedly connected to the positioning rod 204, provides users with a convenient unlocking operation. By simply sliding the slide rod 205, the positioning rod 204 can be driven to retract into the cylinder 202, quickly releasing the locking state between the positioning rod 204 and the positioning groove 104, which is convenient for subsequent adjustment of the position of the adjustable support rod 2 or for storage.

[0028] In this embodiment, the anti-return pawl 403 has a rotating shaft 405 in the middle, which is rotatably connected to the inside of the cavity 102. The anti-return pawl 403 has a power unit 406, and the lever 404 is fixedly connected to the power unit 406. In this embodiment, a connecting plate 407 is fixed between the two power units 406. A through hole 408 communicating with the cavity 102 is opened on one side of the storage groove 101. The through hole 408 cooperates with the positioning rod 204.

[0029] When the lighting fixture is finished using it, the adjustable support rod 2 is rotated and stored. The adjustable support rod 2 will move the positioning rod 204 in sync. Since the through hole 408 on one side of the storage slot 101 is connected to the cavity 102, the positioning rod 204 will move along the through hole 408 into the cavity 102. During the process of the positioning rod 204 entering the cavity 102, its end will squeeze the connecting plate 407 of the winding assembly 4; and the connecting plate 407 is fixedly connected between the power parts 406 of the two anti-return pawls 403, and the squeezing force will synchronously drive the two power parts 406 to move. The working principle of the check pawl 403 is consistent with the lever principle in the prior art: with the rotating shaft 405 as the fulcrum, the movement of the power unit 406 will cause the other end of the check pawl 403 to rotate away from the ratchet 402, thereby quickly releasing the locking restriction between the check pawl 403 and the ratchet 402; at this time, the torsion spring in the cavity 102 will drive the take-up roller 401 to rotate in the opposite direction, automatically winding and taking up the power cord 5, completing the power cord storage operation.

[0030] In this embodiment, the power cord 5 is electrically connected to the lighting body 3, and one end of the power cord 5 is provided with a power plug 501.

[0031] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.
