Description

Technical Field

[0001] This utility model relates to the field of LED desk lamp technology, and more specifically to an LED desk lamp with a USB interface. Background Technology

[0002] An LED desk lamp is a desk lamp that uses LEDs (light-emitting diodes) as its light source. It typically consists of a base, a support frame, and a lamp head. The lamp head contains an LED light panel. To facilitate the connection and charging of mobile phones with the lamp, these desk lamps usually have a USB interface (such as the USB interface set in the patent with publication number CN205956889U).

[0003] However, when traditional USB connectors are combined with desk lamps, the USB interface is often directly exposed. When not in use, it is easy for dust, hair, fibers and other debris to accumulate. Long-term accumulation of these debris may cause poor contact of the interface, affecting the charging function. In severe cases, it may even block the metal contacts inside the interface and cause a short circuit. At the same time, if a cup of water is spilled or hands are wet during daily use, liquid may seep into the interface, which may not only corrode the internal metal parts, but also cause circuit failures and pose a safety hazard. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an LED desk lamp with a USB interface to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: an LED desk lamp with a USB interface, including an LED desk lamp body and a base installed at the bottom of the LED desk lamp body. A locking block is fixedly embedded inside the base. A sliding groove is opened inside the base. A sealing component is installed longitudinally inside the sliding groove. A positioning post is slidably connected to the inside of the base. A limiting groove is opened on the surface of the positioning post. An elastic block is fixedly connected to the surface of the positioning post away from the sliding groove. A pressure rod is slidably connected to the inside of the base. A limiting ring is fixedly sleeved on the outer surface of the pressure rod. A return spring is movably installed on the outer surface of the pressure rod below the limiting ring. The end of the pressure rod abuts against the surface of the limiting groove.

[0006] Furthermore, the sealing assembly includes a sliding disc that is longitudinally slidably connected inside the base. A return spring is fixedly installed at the bottom of the sliding disc. A connecting rod is fixedly connected at the top center of the sliding disc. A sliding seat is fixedly connected at the top of the connecting rod. A USB connector is horizontally fixedly installed inside the sliding seat. A square groove is formed on the surface of the sliding seat away from the USB connector. The end face of the positioning post is engaged inside the square groove. A top plate is fixedly connected to the top of the sliding seat. A sealing ring is fixedly connected to the bottom of the top plate.

[0007] Furthermore, the sliding seat is electrically connected to the internal controller of the LED desk lamp body, and the elastic block is a silicone block. Under normal conditions, the positioning column slides away from the elastic block due to the elasticity of the elastic block.

[0008] Furthermore, the end of the pressure rod is arc-shaped, the top diameter of the pressure rod is larger than the bottom diameter, the limiting groove is trapezoidal, and the surface of the positioning post away from the elastic block is inclined, with the tip of the inclined surface pointing downwards.

[0009] Furthermore, the USB connector's connecting cable is movably connected inside the base, and the length of the USB connector's movable reserved cable inside the base is greater than the length of the connecting rod. The height of the locking block near the sealing component is less than the height of the other end, and the upper surface of the locking block extends to the upper surface of the base and is flush with the upper surface of the base.

[0010] Furthermore, a groove is provided at the center of the surface of the card block, the card block is a silicone plate, the diameter of the top opening of the groove is smaller than the diameter of the sealing ring, and the bottom of the sealing ring is sealed and fitted to the top wall of the groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model effectively solves the defect of exposed USB interface in traditional LED desk lamps by setting a sealing component and positioning structure. Under normal conditions, the sealing ring fits tightly against the top wall of the slide groove. Combined with the closed structure of the sliding seat and base, it can prevent dust, hair and other debris from entering the USB connector, avoiding contact blockage or poor contact. At the same time, the sealing design can prevent liquid seepage, reduce the risk of corrosion of metal parts and short circuit. In addition, the card block is made of silicone material and has grooves. After the data cable is connected, it can tightly wrap the cable body, which not only enhances the connection between the data cable and the USB connector, but also further blocks the path of external moisture or impurities to enter through the gaps in the cable body, significantly improving the safety and service life of the interface.

[0013] 2. This utility model achieves rapid switching of the USB interface state through the cooperation of the elastic block, the pressure rod, and the return spring. Pressing the pressure rod releases the locking of the positioning post to the sliding seat, and the return spring automatically pops out the USB connector, making it convenient for users to quickly connect the device. After use, pressing down the top plate will allow the positioning post to lock into the square groove for sealing and fixation. The operation is simple and efficient. At the same time, the inclined surface design of the positioning post and the trapezoidal structure of the limiting groove ensure the smoothness of the locking process, while the silicone material of the elastic block provides stable rebound force to prevent positioning loosening. The length of the USB connector's pre-reserved connecting wire is greater than the length of the connecting rod, ensuring that the wire is not pulled when the sliding seat slides up and down, thus balancing structural flexibility and circuit stability.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] An LED desk lamp with a USB interface includes an LED desk lamp body 1 and a base 2 installed at the bottom of the LED desk lamp body 1. A locking block 3 is fixedly embedded inside the base 2. A sliding groove 4 is opened inside the base 2. A sealing component 5 is installed longitudinally inside the sliding groove 4. A positioning post 6 is slidably connected to the inside of the base 2. A limiting groove 7 is opened on the surface of the positioning post 6. An elastic block 8 is fixedly connected to the surface of the positioning post 6 away from the sliding groove 4. A pressure rod 9 is slidably connected to the inside of the base 2. A limiting ring is fixedly sleeved on the outer surface of the pressure rod 9. A return spring 10 is movably installed on the outer surface of the pressure rod 9 below the limiting ring. The end of the pressure rod 9 abuts against the surface of the limiting groove 7.

[0023] In this embodiment, the locking block 3 inside the base 2 enhances the sealing performance of the connection with the outer surface of the external data cable, and the sliding groove 4 provides a stable sliding track for the sealing component 5; the sealing component 5 can seal and protect the USB interface; the positioning post 6 and the limiting groove 7, together with the pressure rod 9 and the return spring 10, can achieve precise positioning and quick unlocking of the sealing component 5. The overall structure not only ensures the sealing performance of the USB interface 55 when it is not in use, but also enables the interface to be turned on and off through simple operation, thus improving the practicality and safety of the desk lamp.

[0024] Specifically, the sealing assembly 5 includes a sliding disk 51 that is longitudinally slidably connected inside the base 2. A return spring 52 is fixedly installed at the bottom of the sliding disk 51. A connecting rod 53 is fixedly connected at the top center of the sliding disk 51. A sliding seat 54 is fixedly connected at the top of the connecting rod 53. A USB connector 55 is horizontally fixedly installed inside the sliding seat 54. A square groove 56 is opened on the surface of the sliding seat 54 away from the USB connector 55. The end face of the positioning post 6 is engaged inside the square groove 56. A top plate 57 is fixedly connected to the top of the sliding seat 54. A sealing ring 58 is fixedly connected to the bottom of the top plate 57.

[0025] In this embodiment, the sliding plate 51 can drive the connecting rod 53 and the sliding seat 54 to rise and fall flexibly under the action of the return spring 52, so that the USB connector 55 can easily extend out of the base 2; the sliding seat 54 provides a mounting carrier for the USB connector 55, and the square groove 56 on its surface cooperates with the positioning post 6 to achieve positioning; when the USB connector 55 is not in use, the top plate 57 and the sealing ring 58 can fit tightly against the top wall of the slide groove 4 to form an effective seal, prevent foreign matter and liquid from entering, and protect the USB connector 55 from damage.

[0026] Specifically, the sliding seat 54 is electrically connected to the internal controller of the LED desk lamp body 1, and the elastic block 8 is a silicone block. Under normal conditions, the positioning column 6 slides away from the elastic block 8 due to the elasticity of the elastic block 8.

[0027] In this embodiment, the sliding seat 54 is electrically connected to the internal controller of the LED desk lamp body 1 to ensure that the USB connector 55 can be powered normally; the elastic block 8 is a silicone block, which uses its elasticity to keep the positioning post 6 locked to the sliding seat 54 under normal conditions, ensuring the sealing performance of the sealing component 5. At the same time, the silicone material has good elasticity and durability, and can provide elastic force stably for a long time to ensure reliable positioning.

[0028] Specifically, the end of the pressure rod 9 is arc-shaped, the top diameter of the pressure rod 9 is larger than the bottom diameter, the limiting groove 7 is trapezoidal, and the surface of the positioning post 6 away from the elastic block 8 is inclined, with the tip of the inclined surface pointing downwards.

[0029] In this embodiment, the end of the pressure rod 9 is arc-shaped and the top diameter is larger than the bottom diameter, which facilitates the pressing operation and prevents the pressure rod 9 from extending excessively into the base 2; the limiting groove 7 is trapezoidal and cooperates with the end of the pressure rod 9, so that the pressure rod 9 can push the positioning post 6 to move more smoothly when pressed; the surface of the positioning post 6 away from the elastic block 8 is inclined and the tip is downward. When the sliding seat 54 descends, the positioning post 6 can automatically retract through the guiding effect of the inclined surface, which facilitates the smooth reset and locking of the sliding seat 54 and improves the smoothness of operation.

[0030] Specifically, the connecting cable of the USB connector 55 is movably connected inside the base 2, and the length of the reserved cable of the USB connector 55 inside the base 2 is greater than the length of the connecting rod 53. The height of the end of the locking block 3 near the sealing component 5 is less than the height of the other end, and the upper surface of the locking block 3 extends to the upper surface of the base 2 and is flush with the upper surface of the base 2.

[0031] In this implementation, the length of the reserved wire of the USB connector 55 is greater than the length of the connecting rod 53, ensuring that the wire will not be pulled when the sliding base 54 slides up and down, avoiding damage to the wire and ensuring stable circuit connection; the end of the card block 3 near the sealing component 5 is lower in height, making it easier to insert the data cable, while the other end is higher in height, which can better fix the data cable, and the upper surface of the card block 3 is flush with the upper surface of the base 2, which does not affect the overall aesthetics of the desk lamp, while enhancing the stability after the data cable is connected to the USB connector 55.

[0032] Specifically, a groove is provided at the center of the surface of the card block 3. The card block 3 is a silicone plate. The diameter of the top opening of the slide 4 is smaller than the diameter of the sealing ring 58. The bottom of the sealing ring 58 is sealed and fitted to the top wall of the slide 4.

[0033] In this embodiment, the card block 3 is a silicone plate with grooves on its surface. The silicone material has good elasticity and sealing properties. The grooves can accommodate data cables of different diameters, so that the data cable can fit tightly against the card block 3 after being inserted, enhancing the sealing and connection. The diameter of the top opening of the slide 4 is smaller than the diameter of the sealing ring 58, ensuring that the sealing ring 58 can fit tightly against the top wall of the slide 4, forming an effective seal, preventing debris and liquid from entering the interior of the base 2 through the slide 4, and further protecting the USB connector 55 and the internal circuitry.

[0034] The working principle and usage process of this utility model are as follows: When the USB connector 55 is needed, press down on the pressure rod 9 with your finger. The end of the pressure rod 9 abuts against the inner wall of the limiting groove 7, causing the positioning post 6 to slide to the left. When the end face of the positioning post 6 disengages from the inside of the square groove 56, the elasticity of the return spring 52 causes the sliding plate 51 to slide upward through the connecting rod 53, exposing the USB connector 55 to the outside of the base 2. Then, after connecting the data cable to the USB connector 55, press the section of the data cable close to the base 2 into the inside of the locking block 3. At this time, the data cable... The cable sheath is sealed and fitted inside the card block 3. Due to the friction between the data cable and the card block 3, the connection between the data cable and the USB connector 55 is strengthened. Then, downward pressure is applied to the top of the top plate 57, causing the top plate 57 to slide the sliding seat 54 downward until the top plate 57 is sealed and fitted against the top wall of the slide groove 4 through the sealing ring 58. At the same time, the elasticity of the elastic block 8 causes the positioning post 6 to engage inside the square groove 56, thereby positioning the sliding seat 54. At this time, the inside of the slide groove 4 has good sealing performance, ensuring the safety of the connection between the USB connector 55 and the data cable.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
