Description

Technical Field

[0001] This utility model relates to the technical field of lamp fixing bases, and in particular to an anti-loosening fixing base for lamps. Background Technology

[0002] Lamp bases, such as those for medical lamps, are commonly used in beauty salons or hospitals. Currently, the most common lamp bases on the market can be divided into two types: fixed and integrated. Fixed brackets are generally fixed to the wall or medical bed and cannot be moved; integrated brackets can be moved, but the brackets are larger and can only be used with one type of lamp.

[0003] A search revealed a utility model patent with publication number CN213420878U, which discloses a bracket comprising: a fixed tube; a base mounted on the bottom of the fixed tube, at least two sets of which are detachable; an adjusting tube inserted into the fixed tube, the relative position of which is adjustable; a mounting tube mounted on one end of the adjusting tube; a mounting plate mounted on the mounting tube, at least one set of which is present; and an adjusting assembly, one end of which is connected to the mounting plate and can rotate around the adjusting tube via the mounting tube.

[0004] A review of existing technologies reveals the following shortcomings of the aforementioned patent: While it enables the fixed installation of various lamps, the tightening force relies on traditional screws. During prolonged use and movement of the bracket, the lack of an anti-loosening structure makes the screws prone to loosening, leading to instability and wobbling of the lamps on the bracket. Therefore, a non-loosening fixing base for lamps is urgently needed to address these issues. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-loosening fixing base for lighting fixtures. Its advantages lie in the fact that the first threaded rod and the semi-locking hole inside the second anti-loosening plate interlock, with the semi-locking hole limiting and locking the first threaded rod to prevent it from loosening due to movement during long-term use. This ensures the stability of the lighting fixture installation and avoids instability or wobbling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A locking base for a lighting fixture, comprising:

[0008] Base frame;

[0009] The positioning frame is used to limit the position of the lamp body. The top of the base frame has a positioning groove, and the positioning frame is fixedly connected to the inside of the positioning groove.

[0010] The crossbars are fixedly connected to both ends of the base frame;

[0011] Locking components used to secure the lamp body;

[0012] Anti-loosening components to prevent the locking components from loosening.

[0013] The above technical solutions can jointly achieve stable installation and protection of the lamp body.

[0014] The present invention is further configured such that the locking assembly includes a second threaded hole formed on one side of the outer wall of the positioning frame, a first threaded rod is threadedly connected to the inside of the second threaded hole, a knob is fixedly connected to one end of the first threaded rod, and a locking plate is fixedly connected to the other end of the first threaded rod away from the knob, and the locking plate abuts against one side of the outer wall of the positioning frame.

[0015] The above technical solutions effectively lock and fix the lamp body, ensuring the stability of the lamp during use.

[0016] The present invention is further configured such that a protective pad is adhered to one side of the inner wall of the positioning frame, and the protective pad corresponds one-to-one with the locking plate.

[0017] Through the above technical solution, when the locking plate is pressed against the lamp body, the protective pad can prevent the locking plate from making direct hard contact with the lamp body, thus preventing scratches or damage to the surface of the lamp body.

[0018] The present invention is further configured such that the anti-loosening component includes a first anti-loosening plate and a second anti-loosening plate, and a semi-clamping hole is provided on one side of the second anti-loosening plate, the semi-clamping hole being engaged with the first threaded rod.

[0019] The above technical solution uses a semi-clamping hole to limit and lock the first threaded rod, preventing it from loosening due to movement or other reasons during long-term use.

[0020] The present invention is further configured such that a support seat is fixedly connected to one side of the outer wall of the second anti-loosening plate, and a rotating seat is fixedly connected to one end of the second anti-loosening plate. A first threaded hole and a round hole are respectively opened on both sides of the rotating seat. A second threaded rod is threadedly connected to the first threaded hole. One end of the second threaded rod passes through the inside of the round hole. A fixing sleeve is fixedly connected to the outer circumference of the second threaded rod. The fixing sleeve is fixedly connected to the first anti-loosening plate.

[0021] The above technical solution enables the opening and closing of the first and second anti-loosening plates by rotating the second threaded rod. At the same time, the second threaded rod and the first threaded hole form a threaded connection, which has a good self-locking effect and ensures the stability of the second anti-loosening plate when opening and closing.

[0022] The present invention is further configured such that a throttle is fixedly connected to one end of the second threaded rod.

[0023] The above technical solution allows workers to easily rotate the second threaded rod, providing a convenient point of force for opening and closing the second anti-loosening plate.

[0024] The present invention is further configured such that a second limiting disc is fixedly connected to the end of the second threaded rod away from the throttle, and a first limiting disc is fixedly connected to the outer circumferential wall of the second threaded rod.

[0025] The above technical solutions can limit the range of movement of the second threaded rod, preventing it from detaching from the rotating seat or undergoing excessive displacement during rotation.

[0026] The present invention is further configured such that support frames are provided at both ends of the base frame, and the two ends of the support frames are fixedly connected to the positioning frame and the crossbar, respectively.

[0027] The above technical solutions further enhance the connection strength between the positioning frame, crossbar, and base frame.

[0028] The present invention is further configured such that both ends of the crossbar are provided with casters, and the crossbar and the base frame have an I-shaped cross section.

[0029] The above technical solution involves an I-shaped cross-section for the crossbar and the base frame, which increases the connection area and structural strength between the crossbar and the base frame.

[0030] The beneficial effects of this utility model are as follows:

[0031] 1. This utility model uses a knob to rotate the first threaded rod, causing the locking plate to gradually approach and press against the outer wall of the lamp body, thereby effectively locking and fixing the lamp body and ensuring the stability of the lamp during use.

[0032] 2. In this utility model, the first threaded rod and the semi-locking hole inside the second anti-loosening plate are interlocked. The semi-locking hole plays a role in limiting and locking the first threaded rod, preventing it from loosening due to movement or other reasons during long-term use, ensuring the stability of the lamp installation, and avoiding the lamp from shaking or becoming unstable.

[0033] 3. In this utility model, when it is necessary to disassemble the lamp body, turning the handle drives the second threaded rod to rotate. Since the fixing sleeve on the outer wall of the second threaded rod is fixedly connected to the first anti-loosening plate, the second anti-loosening plate can be opened quickly, the half-locking hole is separated from the first threaded rod, the restriction and jamming effect on the first threaded rod is released, and it is convenient for the staff to unlock the locking component, so as to realize the quick disassembly of the lamp body.

Detailed Implementation

[0041] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0042] Reference Figures 1-6 A locking base for a lighting fixture, comprising:

[0043] Base frame 2 provides stable foundation support for the entire fixed base;

[0044] The positioning frame 6 is used to limit the position of the lamp body 1. The top of the base frame 2 is provided with a positioning groove 7. The positioning frame 6 is fixedly connected inside the positioning groove 7. The positioning frame 6 is fixedly connected inside the positioning groove 7 at the top of the base frame 2, which can initially limit the position of the lamp body 1 and make it in a suitable position on the fixed base.

[0045] The crossbar 3 is fixedly connected to both ends of the base frame 2, and serves to connect and reinforce the base frame 2, thereby enhancing the stability of the overall structure.

[0046] A locking assembly for securing the lamp body 1;

[0047] The locking component 12 is used to prevent the locking component from loosening. The locking component and the anti-loosening component 12 are used to fix the lamp body 1 and prevent the locking component from loosening, respectively. The components cooperate with each other to achieve stable installation and protection of the lamp body 1.

[0048] To ensure the stability of the lighting fixtures during use, refer to Figure 2 Figure 4 The locking assembly includes a second threaded hole 13 on one side of the outer wall of the positioning frame 6. A first threaded rod 11 is threadedly connected inside the second threaded hole 13. A knob 10 is fixedly connected to one end of the first threaded rod 11, and a locking plate 9 is fixedly connected to the other end of the first threaded rod 11 away from the knob 10. The locking plate 9 abuts against one side of the outer wall of the positioning frame 6. By rotating the knob 10, the first threaded rod 11 can be rotated. Due to the threaded engagement between the first threaded rod 11 and the second threaded hole 13, the first threaded rod 11 moves axially during rotation, thereby causing the locking plate 9 to gradually approach and abut against the outer wall of the lamp body 1, thus achieving effective locking and fixing of the lamp body 1.

[0049] To prevent scratches or damage to the surface of the lamp body 1 and to provide good protection, refer to Figure 2 Figure 4 A protective pad 8 is attached to one side of the inner wall of the positioning frame 6. The protective pad 8 corresponds to the locking plate 9. When the locking plate 9 presses against the lamp body 1, the protective pad 8 can prevent the locking plate 9 from making direct hard contact with the lamp body 1.

[0050] To ensure the stability of the light fixture installation and prevent it from shaking or becoming unstable, please refer to... Figure 4 Figure 6 The anti-loosening component 12 includes a first anti-loosening plate 1201 and a second anti-loosening plate 1202. A semi-locking hole 1211 is provided on one side of the second anti-loosening plate 1202. The semi-locking hole 1211 engages with the first threaded rod 11. The semi-locking hole 1211 limits and locks the first threaded rod 11, preventing it from loosening due to movement or other reasons during long-term use.

[0051] In order to achieve rapid opening and closing of the second anti-loosening plate 1202, refer to Figure 5 Figure 6A support seat 1203 is fixedly connected to one outer wall of the second anti-loosening plate 1202. The support seat 1203 provides additional support for the second anti-loosening plate 1202, enhancing its stability. A rotating seat 1205 is fixedly connected to one end of the second anti-loosening plate 1202. A first threaded hole 1210 and a round hole are respectively opened on both sides of the rotating seat 1205. A second threaded rod 1206 is internally threaded into the first threaded hole 1210. One end of the second threaded rod 1206 passes through the inside of the round hole. A fixed sleeve 1207 is fixedly connected to the outer circumference of the second threaded rod 1206. The fixed sleeve 1207 is fixedly connected to the first anti-loosening plate 1201. By rotating the second threaded rod 1206, the opening and closing actions of the first anti-loosening plate 1201 and the second anti-loosening plate 1202 can be realized. At the same time, a threaded connection is formed between the second threaded rod 1206 and the first threaded hole 1210, which has a good self-locking effect and ensures the stability of the second anti-loosening plate 1202 when it is opened and closed.

[0052] To facilitate better rotation of the second threaded rod 1206 by the staff, refer to... Figure 6 One end of the second threaded rod 1206 is fixedly connected to a handle 1204, which makes it convenient for workers to manually rotate the second threaded rod 1206, providing a convenient force application point for the opening and closing operation of the second anti-loosening plate 1202.

[0053] To ensure the stability and reliability of the anti-loosening component 12 structure, refer to Figure 5 Figure 6 The second threaded rod 1206 is fixedly connected to a second limiting plate 1209 at one end away from the throttle 1204. The outer circumferential wall of the second threaded rod 1206 is fixedly connected to a first limiting plate 1208. The first limiting plate 1208 and the second limiting plate 1209 can limit the movement range of the second threaded rod 1206, preventing the second threaded rod 1206 from disengaging from the rotating seat 1205 or from excessive displacement during rotation.

[0054] To improve the stability and load-bearing capacity of the entire fixed base, refer to Figures 1-3 Both ends of the base frame 2 are equipped with support frames 5, and both ends of the support frames 5 are fixedly connected to the positioning frame 6 and the crossbar 3 respectively, which further enhances the connection strength between the positioning frame 6, the crossbar 3 and the base frame 2.

[0055] To improve the overall stability and deformation resistance of the fixed base, refer to Figures 1-3 Both ends of the crossbar 3 are equipped with casters 4. The cross-section of the crossbar 3 and the base frame 2 is I-shaped. This structural design increases the connection area and structural strength between the crossbar 3 and the base frame 2.

[0056] Working principle: When in use, the operator first inserts the end of the lamp body 1 into the positioning frame 6, and then rotates the knob 10. The knob 10 drives the first threaded rod 11 to rotate. During the rotation of the first threaded rod 11, the locking plate 9 can gradually move closer to the lamp body 1 until the locking plate 9 presses against the outer wall of the lamp body 1, thereby achieving the locking and fixing of the lamp body 1. While the locking assembly locks and fixes the lamp body 1, the first threaded rod 11 will engage with the semi-locking hole 1211 opened inside the first anti-loosening plate 1201 and the second anti-loosening plate 1202. Since the semi-locking hole 1211 and the first threaded rod 11 engage with each other, the first threaded rod 11 can be limited and locked to prevent it from rotating loosely, thus achieving a good anti-loosening effect.

[0057] When the staff needs to disassemble the lamp body 1, they can rotate the handle 1204 to drive the second threaded rod 1206 to rotate. The outer wall of the second threaded rod 1206 is fixedly connected to the fixing sleeve 1207, which allows the second anti-loosening plate 1202 to open quickly. When the second anti-loosening plate 1202 opens, the semi-locking hole separates from the first threaded rod 11, thereby releasing the restriction and jamming effect on the first threaded rod 11. This facilitates the subsequent unlocking of the locking components by the staff, allowing people to quickly disassemble the lamp body 1.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
