[0013] It also relates to a lamp, including the rotating structure for the lamp as described in any of the above technical solutions.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This application sets up a rotating mechanism with a rotating shaft as the core support. The turntable rotates and is sleeved on the surface of the rotating shaft, which can drive the fixedly connected rotating plate to rotate around the rotating shaft. Several pillars fixed at the top of the turntable are equipped with ball bearings at the bottom. The ball bearings contact the support plate, which can greatly reduce the friction between the turntable and the support plate when the turntable rotates, ensuring smooth rotation of the rotating plate. At the same time, the rotating column connected by the internal thread of the turntable can drive the bottom limiting plate to move down through rotation, so that the first rubber pad at the bottom of the limiting plate is tightly attached to the top of the support plate. The friction force is used to stabilize and limit the turntable and the rotating plate, realizing the position locking of the turntable and the rotating plate after rotation adjustment. Combined with the movable sliding sleeve on the rotating plate, the lamp body can finally flexibly adjust its position within a circular range with the rotating plate as the radius and the rotating shaft as the center.
[0016] 2. This application uses a limiting mechanism, which is fixed to the sliding sleeve by a bracket. The limiting post inside the bracket is connected to the connecting plate at the top and fixed to the pressure plate at the bottom. The second rubber pad at the bottom of the pressure plate can contact the top of the rotating plate. The connecting plate has a pull ring at the top and tension springs on both sides at the bottom. The other end of the tension spring is fixed to the sliding sleeve. When the pull ring is pulled upward, the tension spring extends, and the limiting post drives the pressure plate and the second rubber pad to move upward and separate from the rotating plate, releasing the limiting of the sliding sleeve. This allows the sliding sleeve to move the lamp body on the rotating plate. After the pull ring is released, the tension spring retracts and pulls the connecting plate downward, so that the second rubber pad is pressed against the rotating plate again. The friction force locks the position of the sliding sleeve, ensuring the stability of the lamp body after adjustment. Attached Figure Description

[0023] 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.
[0024] Please see Figure 1-5 The present invention provides the following technical solution:
[0025] A rotating structure for a lamp and a lamp fixture include a mounting plate 1, a rotating shaft 2 fixedly connected to the bottom of the mounting plate 1, a support plate 4 fixedly connected to the bottom of the rotating shaft 2, a rotating mechanism 3 provided on the surface of the rotating shaft 2, a lamp fixture body 5 provided on the left side of the support plate 4, and a limiting mechanism 8 provided on the top of the lamp fixture body 5; the rotating mechanism 3 includes a rotating plate 301, a turntable 302, a plurality of balls 303 and a plurality of supports 304, the right side of the rotating plate 301 is fixedly connected to the left side of the turntable 302, the turntable 302 is rotatably sleeved on the surface of the rotating shaft 2, the balls 303 are rotatably connected to the bottom of the supports 304, the top of the supports 304 is fixedly connected to the top of the turntable 302, and the bottom of the balls 303 is in contact with the top of the support plate 4.
[0026] In this embodiment: the mounting plate 1 can be fixed in the installation position by passing an external bolt through the mounting hole 16. The turntable 302 rotates and is sleeved on the rotating shaft 2, so that the rotating plate 301 and the turntable 302 can rotate around the rotating shaft 2. The ball bearing 303 at the bottom of the top support column 304 of the turntable 302 contacts the support plate 4 to reduce rotational friction. The lamp body 5 is connected to the sliding sleeve 7 via the fixing bracket 9 and screws 10. The sliding sleeve 7 is sleeved on the rotating plate 301 and can move. Combined with the rotation of the rotating plate 301, the lamp can be adjusted within a circular range with the rotating plate 301 as the radius and the rotating shaft 2 as the center, improving the lighting range and utilization rate. Rotating the rotating column 11 can move the limiting plate 12 down, and the first rubber pad 13 is pressed against the support plate 4. The rotating plate 301 and the turntable 302 are fixed by friction. Pulling the pull ring 14 causes the tension spring 15 to extend, and the second rubber pad 805 disengages from the rotating plate 301, allowing the movable sliding sleeve 7 and the lamp to move. Releasing the pull ring 14 causes the tension spring 15 to retract and pull the second rubber pad 805 to adhere tightly to the rotating plate 301, thus fixing it by friction. The tops of both the rotating plate 301 and the support plate 4 are rough-polished to enhance friction. The limiting block 6 prevents the sliding sleeve 7 from coming off the surface of the rotating plate 301. This solves the problem that some existing lamps have a limited adjustment range after installation, making it inconvenient to adjust the position of the lamps widely according to usage needs, affecting the flexibility and illumination range of the lamps, and hindering the maximization of lamp utilization.
[0027] Specifically, such as Figure 3 As shown, the turntable 302 is internally threaded with a rotating column 11. The bottom of the rotating column 11 is rotatably connected to a limiting disk 12. The bottom of the limiting disk 12 is fixedly connected to a first rubber pad 13. The bottom of the first rubber pad 13 is in close contact with the top of the support plate 4.
[0028] Specifically, such as Figure 1 As shown, mounting plate 1 has mounting holes 16 inside, and the number of mounting holes 16 is several and they are evenly distributed inside the mounting plate 1.
[0029] Specifically, such as Figure 1 and Figure 2As shown, a sliding sleeve 7 is movably fitted on the surface of the rotating plate 301, and a fixing frame 9 is fixedly connected to the top of the lamp body 5. Screws 10 are provided on the front and rear sides of the bottom of the fixing frame 9. The top of the screws 10 passes through the fixing frame 9 and is connected to the internal thread of the sliding sleeve 7.
[0030] In this embodiment: the rotating column 11 is threadedly engaged with the turntable 302, and the position of the turntable 302 can be securely locked by the limiting plate 12 and the first rubber pad 13 to ensure stability after rotation. Multiple evenly distributed mounting holes 16 facilitate the flexible fixing of the mounting plate 1. The sliding sleeve 7 is movably engaged with the rotating plate 301. Combined with the fixing bracket 9 and screws 10, a stable connection between the lamp body 5 and the sliding sleeve 7 is achieved, which facilitates the movement and adjustment of the lamp body 5 along the rotating plate 301.
[0031] Specifically, such as Figure 1 and Figure 4 As shown, the limiting mechanism 8 includes a connecting plate 801, two limiting posts 802, two brackets 803, two pressure plates 804, and two second rubber pads 805. The bottom of the connecting plate 801 is fixedly connected to the top of the limiting posts 802. The limiting posts 802 are slidably connected inside the brackets 803. The bottom of the brackets 803 is fixedly connected to the top of the sliding sleeve 7. The top of the pressure plate 804 is fixedly connected to the bottom of the limiting posts 802. The top of the second rubber pads 805 is fixedly connected to the bottom of the pressure plate 804. The bottom of the second rubber pads 805 is in contact with the top of the rotating plate 301.
[0032] Specifically, such as Figure 2 and Figure 4 As shown, tension springs 15 are fixedly connected to both sides of the bottom of the connecting plate 801. The bottom of the tension springs 15 is fixedly connected to the top of the sliding sleeve 7. A pull ring 14 is fixedly connected to the top of the connecting plate 801.
[0033] Specifically, such as Figure 1 As shown, the tops of the rotating plate 301 and the support plate 4 are both rough-polished, and the front and rear sides of the rotating plate 301 are fixedly connected to limit blocks 6.
[0034] In this embodiment: the limiting mechanism 8 can effectively lock the position of the sliding sleeve 7 through the limiting post 802, the pressure plate 804, and the second rubber pad 805, ensuring the stability of the lamp body 5 after movement. The design of the tension spring 15 and the pull ring 14 makes the unlocking operation of the sliding sleeve 7 convenient and effortless. The top of the rotating plate 301 and the support plate 4 are roughened to enhance the friction limiting effect. The limiting block 6 prevents the sliding sleeve 7 from falling off and improves the structural safety.
[0035] This utility model also provides a lamp, including a rotating structure for the lamp according to any of the technical solutions. All lamps except for the rotating structure for the lamp described above are existing technologies and will not be described in detail here.
[0036] In this embodiment, the lamp with the above-mentioned rotating structure has a wide range of position adjustment capabilities, a wide lighting range and flexible adjustment, can adapt to diverse usage needs, and improve the utilization rate and practicality of the lamp.
[0037] Working principle: The mounting plate 1 is securely installed by passing external bolts through the mounting holes 16 and fixing it to the mounting position. The turntable 302 rotates and is fitted onto the surface of the rotating shaft 2, allowing the rotating plate 301 and the turntable 302 to rotate around the rotating shaft 2. Several support columns 304 fixed at the top of the turntable 302 are rotatably connected to the bottom of the ball bearings 303. The bottom of the ball bearings 303 contacts the top of the support plate 4. When the rotating plate 301 and the turntable 302 rotate, the ball bearings 303 can reduce the friction between the turntable 302 and the support plate 4, making the rotation of the turntable 302 smoother. The lamp body 5 is connected to the sliding sleeve 7 through the fixing bracket 9 and screws 10. The sliding sleeve 7 is movably fitted onto the surface of the rotating plate 301, which allows the sliding sleeve 7 to drive the lamp body 5 to rotate on the rotating plate 301. 01 Surface movement, combined with the rotation of the rotating plate 301 around the rotating shaft 2, allows the lamp body 5 to be adjusted to any position within a circular range with the rotating plate 301 as the radius and the rotating shaft 2 as the center, effectively improving the lighting range and utilization rate of the lamp body 5. When it is necessary to fix the positions of the rotating plate 301 and the turntable 302, the rotating column 11 connected by the internal thread of the turntable 302 is rotated, and the limiting plate 12 connected to the bottom of the rotating column 11 moves downward accordingly. The first rubber pad 13 fixed at the bottom of the limiting plate 12 is in close contact with the top of the support plate 4, and the friction between the first rubber pad 13 and the support plate 4 is used to limit the turntable 302 and the rotating plate 301. In the limiting mechanism 8, the limiting column 802 fixed at the bottom of the connecting plate 801 slides and connects... The bracket 803 is connected inside the bracket 803, and the bottom of the bracket 803 is fixed to the top of the sliding sleeve 7. When the pull ring 14 on the top of the connecting plate 801 is pulled upward, the tension springs 15 fixed on both sides of the bottom of the connecting plate 801 are stretched. The limiting post 802 drives the pressure plate 804 and the second rubber pad 805 to move upward, so that the second rubber pad 805 is disengaged from the rotating plate 301. At this time, the position of the sliding sleeve 7 and the lamp body 5 on the surface of the rotating plate 301 can be easily moved. After the position is adjusted, the pull ring 14 is released, the tension spring 15 retracts, and the connecting plate 801 is pulled downward, which in turn drives the second rubber pad 805 to move downward, so that the bottom of the second rubber pad 805 is in close contact with the top of the rotating plate 301. The friction between the second rubber pad 805 and the rotating plate 301 is utilized. The friction force limits the position of the sliding sleeve 7 and the lamp body 5. In addition, the tops of the rotating plate 301 and the support plate 4 are rough-polished to increase the friction of the contact surface, making the limiting of the rotating plate 302 and the sliding sleeve 7 more stable. The limiting blocks 6 fixed on the front and rear sides of the rotating plate 301 can prevent the sliding sleeve 7 from coming off the left side of the rotating plate 301. This solves the problem that some existing lamps have a limited adjustment range after installation, making it inconvenient to adjust the position of the lamps according to the usage needs, affecting the flexibility of lamp use and the illumination range, and making it difficult to maximize the use of the lamps. It should be noted that the lamp body 5 is a mature technology that has been published. It is powered by an external power cord and an external power supply. Its basic mechanism will not be elaborated here.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
