Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a track light with a universal rotating structure. Background Technology

[0002] With the development of modern lighting technology, track lights have been widely used in commercial and residential lighting due to their advantages such as flexible installation and high adjustability. Traditional track lights typically consist of a lamp body, connectors, and a base for mounting on a track. However, in practical use, these track lights often have some technical shortcomings.

[0003] First, existing track lights typically use a single hinge or pivot structure for angle adjustment, which limits their degree of freedom and makes it impossible to achieve multi-directional, all-around lighting angle adjustment. For example, some lights can only swing up and down or left and right in a single plane, which is difficult to meet the application scenarios with high requirements for lighting direction, such as situations where light needs to be precisely projected onto a specific location or irregularly shaped object. This lack of adjustment capability limits the applicability and lighting effect of track lights.

[0004] Furthermore, existing track lights typically use threads or clips to secure the light body to the connector. When the light body is damaged and needs repair, or when different types or wattage light heads need to be replaced due to design requirements, the disassembly and replacement process is often cumbersome, requiring tools or complex disassembly operations. This inconvenient disassembly and assembly method increases the workload and time cost of later maintenance, and reduces the user experience.

[0005] Therefore, this utility model proposes a track light with a universal rotating structure to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of low angle adjustment freedom and inconvenient disassembly and replacement of the lamp body in the existing technology, the present invention aims to provide a track light with a universal rotation structure that has been improved and can effectively solve the above problems.

[0007] This utility model provides a track light with a universal rotation structure, including a base and a light body; as well as a universal rotation assembly and a quick-connect assembly.

[0008] One end of the universal joint is rotatably connected to the base, and the quick-connect assembly is used to connect the other end of the universal joint to the lamp body. The universal joint includes a universal joint, two ball joints that rotatably engage with the universal joint, and two first threaded sleeves threadedly connected to the universal joint. The ends of the first threaded sleeves are used to move along their axial direction to press against the ball joints and fix the ball joints inside the universal joint.

[0009] Furthermore, the quick-connect assembly includes a first connector fixedly connected to the lamp body and a second connector fixedly connected to the ball head. A clamping block is movably disposed on the outer periphery of the second connector, and a second threaded sleeve is threadedly connected to the outer wall of the second connector. The second threaded sleeve has a tapered inner wall, which abuts against the outer surface of the clamping block, so that when the second threaded sleeve moves axially, it pushes the clamping block to move radially to clamp or release the first connector.

[0010] Preferably, the track light with a universal rotating structure further includes a locking assembly for locking the base to the track. The locking assembly includes a knob and a screw that is linked to the knob. The base is provided with a screw hole, the screw is screwed into the screw hole, and the end of the screw is used to press against the track.

[0011] Preferably, the outer wall of the universal joint is provided with a limiting groove extending along its axial direction, and a limiting block is fixedly connected to the inner wall of the first threaded sleeve, the limiting block being slidably fitted in the limiting groove.

[0012] Preferably, the end face of the first connector is provided with a protrusion, and the end face of the second connector is provided with a groove that mates with the protrusion.

[0013] Preferably, the outer peripheral wall of the first connector is provided with a slot, and the inner side wall of the clamping block facing the first connector is provided with snapping stripes that snap into the slot.

[0014] Preferably, the clamping blocks are a plurality of blocks arranged in a circumferential array along the second connector.

[0015] Preferably, the universal joint has spherical receiving cavities at both ends for accommodating the ball head, and the end of the first threaded sleeve is used to press against the ball head to press the ball head tightly against the inner wall of the spherical receiving cavity.

[0016] Preferably, one of the ball heads is integrally formed on the end of the second connector away from the first connector, and the other ball head is integrally formed on the base.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of limited angle adjustment range and inflexible locking of track lights in the prior art by setting a universal rotating component and adopting a structure of ball head and threaded sleeve clamping. It realizes the flexible rotation of the light body in all directions and at multiple angles and can be reliably locked. By setting a quick-connect component and adopting a structure of cone-shaped threaded sleeve driving clamping block clamping, it solves the problem of complicated and inconvenient disassembly and replacement of the light body in the prior art. It realizes the quick and stable installation and disassembly of the light body, which facilitates later maintenance and replacement.

[0018] 2. This utility model solves the problem of threaded sleeves potentially falling off due to loosening by setting a limiting block on the first threaded sleeve and cooperating with the limiting groove on the universal joint, thus preventing parts from accidentally falling off and improving the safety and durability of the product. By setting snap-fit ​​stripes on the clamping block to snap into the snap-fit ​​groove on the first connector, it solves the problem of poor torsional resistance of the connection structure in the prior art, further improving the stability and tightness of the lamp body connection and effectively preventing the lamp body from rotating and deviating.

[0021] 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.

[0022] Please refer to Figures 1 to 5 This utility model provides a track light with a universal rotating structure, which aims to solve the problems of limited angle adjustment range and inconvenient disassembly and replacement of the light body 6 in the prior art.

[0023] like Figure 1 and Figure 2 As shown, a track light with a universal rotating structure includes a track 1 and a base 2 slidably mounted on the track 1. The base 2 is provided with a locking assembly 3 for locking its position. The locking assembly 3 includes a knob 301 and a screw 302. The base 2 has a screw hole 303 that is threadedly engaged with the screw 302. The knob 301 and the screw 302 are linked together. By rotating the knob 301, the screw 302 is driven to screw into the screw hole 303. The end of the screw 302 presses against the track 1, thereby firmly locking the base 2 in the designated position on the track 1. A universal rotating assembly 4 is rotatably connected to the base 2. The end of the universal rotating assembly 4 away from the base 2 is connected to the light body 6 through a quick-connect assembly 5.

[0024] Reference Figure 3 The universal joint assembly 4 includes a universal joint 401, two ball heads 402, and two first threaded sleeves 403. One end of the universal joint 401 is provided with a spherical cavity for accommodating the ball heads 402, which rotate within the cavity. The first threaded sleeves 403 are threaded to the outer wall of the universal joint 401, and their ends are used to move axially to press against the ball heads 402, thereby pressing the ball heads 402 against the inner wall of the cavity and fixing the position and angle of the ball heads 402 within the universal joint 401. To prevent the first threaded sleeves 403 from accidentally falling off, the outer wall of the universal joint 401 is also provided with a limiting groove 405 extending axially. A limiting block 404 is fixedly connected to the inner wall of the first threaded sleeves 403, which slides within the limiting groove 405 to limit the rotation range of the first threaded sleeves 403.

[0025] To solve the above-mentioned technical problems, the track light with the universal rotation structure also includes a quick-connect component 5, and the quick-connect component 5 forms a specific structural fit and connection relationship with the aforementioned universal rotation component 4 and the light body 6.

[0026] Please refer to the following carefully. Figure 1 , Figure 3 and Figure 5 The quick-connect component 5 includes a first connector 501 and a second connector 502. The first connector 501 is fixedly connected to the top of the lamp body 6, and the second connector 502 is fixedly connected to the bottom of the ball head 402 of the universal rotating component 4, thereby realizing a detachable connection between the lamp body 6 and the universal rotating component 4. A protrusion 503 is machined on the end face of the first connector 501, and a groove 504 that matches the shape and size of the protrusion 503 is correspondingly provided on the end face of the second connector 502. During connection, the protrusion 503 can be accurately inserted into the groove 504, realizing the initial positioning and alignment of the first connector 501 and the second connector 502, ensuring that the subsequent tightening operation is accurate.

[0027] Meanwhile, multiple clamping blocks 505 are movably arranged on the outer periphery of the second connector 502, and a slot 507 is also provided on the outer peripheral wall of the first connector 501. The clamping blocks 505 have snap-fit ​​stripes 506 machined on their inner sidewalls facing the first connector 501, which match the slot 507. The snap-fit ​​stripes 506 can firmly engage with the slot 507 when the clamping blocks 505 clamp the first connector 501, thereby enhancing the stability and torsional resistance of the connection and effectively preventing the lamp body 6 from accidentally rotating or loosening under external force. A second threaded sleeve 508 is also threaded onto the outer wall of the second connector 502. The inner wall of the second threaded sleeve 508 is designed as a conical inner wall. The inner wall of the conical sleeve 508 abuts against the outer surface of the clamping block 505. When the second threaded sleeve 508 is screwed on, the second threaded sleeve 508 moves along its thread axis. Its conical inner wall applies radial pressure to the clamping block 505, pushing the clamping block 505 to contract towards the center, so that the clamping block 505 firmly clamps the first connector 501. At the same time, the snap-fit ​​stripe 506 and the snap-fit ​​groove 507 are tightly engaged, ensuring the high stability and reliability of the connection between the lamp body 6 and the universal rotating assembly 4. When the lamp body 6 needs to be disassembled or replaced, simply loosen the second threaded sleeve 508 counterclockwise. The radial pressure of the clamping block 505 disappears, and the lamp body 6 can be easily and quickly separated, which facilitates maintenance and replacement operations.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to securely fix the base 2 to the track 1, please refer to... Figure 2 The track light also includes a locking assembly 3, which includes a knob 301 and a screw 302. A screw hole 303 is provided on the base 2. The screw 302 is linked to the knob 301 and threaded through the screw hole 303. The end of the screw 302 is used to press against the surface of the track 1.

[0029] As another preferred embodiment, to prevent the first threaded sleeve 403 from accidentally unscrewing and falling off the universal joint 401, please refer to... Figure 3 The universal joint 401 has a limiting groove 405 extending along its axial direction on its outer wall, and a limiting block 404 is fixedly connected to the inner wall of the first threaded sleeve 403. The limiting block 404 is slidably fitted in the limiting groove 405.

[0030] As a preferred embodiment, to enable quick alignment and positioning during connection, please refer to... Figure 4 and Figure 5 The first connector 501 has a protrusion 503 on its end face, and the second connector 502 has a groove 504 on its end face that can be inserted into the protrusion 503.

[0031] In a preferred embodiment, in order to further improve the tightness and torsional resistance of the connection, the outer peripheral wall of the first connector 501 is provided with a slot 507, and the inner side wall of the clamping block 505 facing the first connector 501 is provided with a snap-fit ​​stripe 506 that can snap into the slot 507.

[0032] In another preferred embodiment, in order to apply a uniform clamping force, the clamping blocks 505 are a plurality of those distributed in a circumferential array along the first connector 501.

[0033] In a preferred embodiment, the universal joint 401 has spherical receiving cavities at both ends for accommodating the ball head 402, and the end of the first threaded sleeve 403 is used to press against the ball head 402 to press the ball head 402 tightly against the inner wall of the spherical receiving cavity.

[0034] In a preferred embodiment, in order to simplify the structure and improve the overall strength, one ball head 402 is integrally formed on the end of the second connector 502 away from the first connector 501, and the other ball head 402 is integrally formed on the base 2.

[0035] The working principle of this utility model of a track light with a universal rotating structure is as follows: During installation and fixing, the base 2 is slidably mounted on the track 1 to the predetermined position, and then the knob 301 of the locking component 3 is turned. The knob 301 drives the screw 302 to screw into the screw hole 303 of the base 2. The end of the screw 302 advances and presses against the track 1, and the pressure and friction generated securely lock the base 2 on the track 1.

[0036] When adjusting the angle, the lamp body 6 is connected to the ball head 402 of the universal joint 4 via the quick-connect assembly 5. The ball head 402 can rotate freely in the spherical cavity of the universal joint 401, thereby driving the lamp body 6 to swing flexibly in any direction. After adjusting to the desired lighting angle, the first threaded sleeve 403 is tightened. The first threaded sleeve 403 moves along the thread axis of the universal joint 401, and its end applies pressure to the ball head 402, increasing the friction between the ball head 402 and the inner wall of the spherical cavity, thereby locking the angle of the ball head 402 and fixing the illumination direction of the lamp body 6. During the process of loosening the first threaded sleeve 403, the limiting block 404 inside it slides in the limiting groove 405 of the universal joint 401 and plays a limiting role when it reaches the end of the limiting groove 405, preventing the first threaded sleeve 403 from falling off.

[0037] When it is necessary to disassemble or replace the lamp body 6, first loosen the second threaded sleeve 508 counterclockwise. The second threaded sleeve 508 moves along the thread axis of the second connector 502, and the radial pressure of its conical inner wall on the clamping block 505 is released. The clamping block 505 is automatically released. At this time, the first connector 501 can be removed together with the lamp body 6. During installation, first align the protrusion 503 of the first connector 501 with the groove 504 of the second connector 502 and insert it to achieve positioning. Then tighten the second threaded sleeve 508 clockwise. When its conical inner wall moves axially, it will squeeze the clamping block 505 inward, causing the clamping block 505 to shrink towards the center and firmly clamp the first connector 501. At the same time, the snap-fit ​​stripe 506 on the clamping block 505 is also tightly engaged with the snap-fit ​​groove 507 on the first connector 501. Through this synergistic effect, the lamp body 6 is quickly installed and securely connected.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
