Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a desktop lift socket. Background Technology

[0002] With the continuous development of electronic devices, such as computers and printers, they are widely used in daily office work. These electronic devices inevitably require power cords. Traditional desks typically have holes in the desktop for power cords to pass through, and when electronic devices need power, the power cord is plugged into a power outlet through the hole. However, this method has some problems: during work, one might accidentally kick the power plug, causing the electronic device to suddenly shut down, affecting work efficiency; additionally, exposed power cords and outlets on the desktop also affect the tidiness of the desktop.

[0003] To address the aforementioned issues and improve desktop tidiness, several improvements have been proposed. For example, Chinese patent document CN102074860A discloses a spring-loaded, liftable desktop socket. This socket is located inside a stretch tube, with an upper end cap at its top. A positioning base slides onto the upper end cap, and a locking ring is fitted over the positioning base. A guide pin connects the handle and the upper end cap, and the guide pin is inserted laterally into the two connection points between the handle and the upper end cap. In use, pressing the handle surface at the top of the socket automatically pops the handle out; pulling the handle exposes the entire socket on the desktop for normal use. After use, pressing the handle surface again retracts the socket back into the desktop, and the handle automatically retracts.

[0004] However, this solution still has some shortcomings. First, it is relatively inconvenient to operate, requiring manual pressing and pulling to expose the socket on the desktop. Second, the socket cannot be positioned at any arbitrary height; it can only be fully exposed or fully concealed, lacking flexibility. Furthermore, this design may increase the user's operational burden, especially in scenarios where socket use is frequent. Summary of the Invention

[0005] In order to solve the above problems, the purpose of this utility model is to provide a desktop height-adjustable socket, which has the advantages of convenient operation, simple structure and safety and reliability.

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

[0007] A desktop height-adjustable socket includes a cylindrical base for being fitted and fixed in a table hole, and a socket body on which at least one socket unit is mounted; a locking ring is threaded onto the outer wall of the cylindrical base for clamping the cylindrical base onto the table hole; the socket body is slidably mounted on the cylindrical base, and a vertically arranged rack is fixedly connected to the inner wall of the cylindrical base; a drive assembly is provided in the lower end of the socket body, the drive assembly including a drive motor and a drive gear driven by the drive motor; the drive gear meshes with the rack, and the drive motor drives the drive gear to rotate forward and backward, thereby raising or lowering the socket body relative to the cylindrical base.

[0008] Furthermore, this application also proposes that the drive assembly further includes a reduction gear connected to the output shaft of the drive motor.

[0009] The output end of the reduction gearbox is connected to the drive gear via a pulley assembly.

[0010] Furthermore, this application also proposes that the rack is fitted onto the outer wall of the socket housing; the drive assembly is disposed inside the socket housing of the socket body, with only the drive gear portion of the drive assembly exposed outside the socket housing and meshing with the rack.

[0011] Furthermore, this application also proposes that a sliding bracket is provided on the outer wall of the socket housing, and the rack is slidably disposed on the sliding bracket; when the socket body moves relative to the cylindrical base, the sliding bracket moves relative to the rack.

[0012] Furthermore, this application also proposes that the rack is constructed in a T-shape or L-shape, and a stop bar is constructed on the upper end of the rack; when the socket body rises to the highest position relative to the cylindrical base, the stop bar at the upper end of the rack abuts against the sliding seat.

[0014] Furthermore, this application also proposes that the interior of the socket housing is constructed with an upper socket chamber and a lower drive chamber, at least one socket unit is disposed in the socket chamber, and the drive assembly is disposed in the drive chamber.

[0015] Furthermore, this application also proposes that an upper limit switch is provided at the upper end of the socket body. When the socket body descends to the lowest position relative to the cylindrical base, the stop bar at the upper end of the rack directly or indirectly triggers the upper limit switch and triggers the drive assembly to stop.

[0016] Furthermore, this application also proposes that the upper end of the socket body is provided with an upper connecting cover; a circuit board is installed inside the upper end of the upper connecting cover, and a control switch is provided on the circuit board; the control switch is a push switch and is located in the middle of the upper end of the circuit board; the upper end of the upper connecting cover is provided with a pressure cover for pressing the control switch; the lower end of the pressure cover abuts against the button of the control switch located at the upper end; the upper limit switch is connected to the lower end of the circuit board, and a pressing block is provided on the upper connecting cover to abut against the upper limit switch; when the socket body descends to the lowest position relative to the cylindrical base, the stop bar at the upper end of the rack triggers the upper limit switch through the pressing block.

[0017] Furthermore, this application also proposes that the cover includes a cover body and a decorative ring disposed on the cover body; the outer periphery of the cover body is equidistantly formed with a plurality of downwardly extending plug arms, and the outer wall of each plug arm is formed with a snap-fit; a locking block is disposed on the inner side wall of the upper connecting cover, and when the cover body is closed on the upper connecting cover, the locking block is engaged in the snap-fit; the circuit board is disposed inside the upper connecting cover below the cover body, and the center of the cover body is elastically supported on the circuit board.

[0018] As described above, the desktop height-adjustable socket provided in this application includes a cylindrical base for being fitted and fixed in a table hole, and a socket body on which at least one socket unit is installed; a locking ring is threaded onto the outer wall of the cylindrical base, the locking ring being used to clamp the cylindrical base onto the table hole; the socket body is slidably mounted on the cylindrical base, and a vertically arranged rack is fixedly connected to the inner wall of the cylindrical base; a drive assembly is provided in the lower end of the socket body, the drive assembly including a drive motor and a drive gear driven by the drive motor; the drive gear meshes with the rack, and the drive motor drives...

[0019] The drive gear rotates forward and backward, causing the socket body to rise or fall relative to the cylindrical base. By using a drive motor to rotate the drive gear, the socket body can rise or fall relative to the cylindrical base, thus solving the problems of inconvenient operation and lack of flexibility of traditional desktop sockets. It offers advantages such as convenient operation, simple structure, and safety and reliability. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] In this utility model, unless otherwise expressly specified and limited, the first feature is "above" or "below" the second feature.

[0033] This can include situations where the first and second features are in direct contact, or situations where the first and second features are in contact through another feature between them.

[0034] like Figures 1-8 As shown, this embodiment provides a desktop height-adjustable socket, including a cylindrical base 1 for being fitted and fixed in a table hole, and a socket body 2 on which at least one socket unit 20 is installed. A locking ring 3 is threaded onto the outer wall of the cylindrical base 1, which clamps the cylindrical base 1 onto the table hole. In use, rotating the locking ring 3 allows it to rotate along the threads on the outer wall of the cylindrical base 1, thereby tightening or loosening the tabletop pressing against or releasing the edge of the table hole. The cylindrical base 1 is fixed in the table hole by the locking ring 3, providing a stable base support.

[0035] In a further embodiment, a drive assembly 4 is disposed within the lower end of the socket body 2. Specifically, the socket housing 21 has an upper socket chamber 22 and a lower drive chamber 23 internally. At least one socket unit 20 is disposed within the socket chamber 22, and the drive assembly 4 is disposed within the drive chamber 23. Specifically, the partitioned design of the socket chamber 22 and the drive chamber 23 effectively avoids mutual interference between the socket unit 20 and the drive assembly 4 during operation through physical isolation. The socket chamber 22 primarily accommodates the socket unit 20, ensuring its stability and safety during use; the drive chamber 23 is used to install the drive assembly 4, including components such as a drive motor and drive gears, to realize the lifting function of the socket body 2. This partitioned design not only improves the stability of the socket but also simplifies the internal structural layout, facilitating maintenance and repair. Therefore, the technical solution of this application, by separately placing the socket unit 20 and the drive assembly 4 within different chambers, achieves independent operating spaces for functional modules, thereby solving the technical problem caused by the unreasonable internal partitioning of the socket housing 21. Compared with existing technologies, this solution not only improves the stability and safety of the socket, but also simplifies the internal structure design, making it easier to produce and maintain.

[0036] The socket body 2 is slidably mounted on the cylindrical base 1, and a vertically arranged rack 5 is fixedly connected to the inner wall of the cylindrical base 1. The drive assembly 4 includes a drive motor 41 and a drive gear 42 driven by the drive motor 41. The drive gear 42 meshes with the rack 5, and the drive motor 41 drives the drive gear 42 to rotate forward and backward, thereby causing the socket body 2 to rise or fall relative to the cylindrical base 1. The drive motor 41 can be a stepper motor or a servo motor to achieve precise control of the lifting height of the socket body 2. The meshing method between the drive gear 42 and the rack 5 can be spur gear meshing or helical gear meshing to improve the smoothness and accuracy of the transmission. Specifically, the socket body 2 is slidably mounted on the cylindrical base 1, allowing the socket body 2 to move up and down as needed. The rack 5 on the inner wall of the cylindrical base 1 meshes with the drive gear 42 inside the socket body 2, and the drive motor 41 drives the socket body 2 to rise or fall through the forward and reverse rotation of the drive gear 42, thereby achieving flexible adjustment of the socket height. By employing the cooperation of drive gear 42 and rack 5, the socket body 2 can be positioned at any height within the adjustment range. Furthermore, the inclusion of drive component 4 makes the lifting and lowering process of the socket body 2 smoother and more controllable, solving the problems of traditional sockets' inflexible height adjustment and insufficient stability. Therefore, the technical solution of this application, through the cooperation of drive motor 41, drive gear 42, and rack 5, achieves flexible lifting and lowering of the socket body 2 and enables positioning at any height. Compared with existing technologies, the technical solution of this application has higher stability and controllability, effectively solving the technical problems of traditional desktop height-adjustable sockets' inflexible height adjustment and insufficient stability during use.

[0037] like Figure 2 and 7As shown, the drive assembly 4 also includes a reduction gearbox 43 connected to the output shaft of the drive motor 41. The output end of the reduction gearbox 43 is connected to the drive gear 42 via a pulley assembly 44. Specifically, the function of the reduction gearbox 43 is to reduce the speed of the drive motor 41 and increase the torque, thereby ensuring that the drive gear 42 can mesh with the rack 5 at an appropriate speed and torque, achieving smooth lifting and lowering of the socket body 2. The pulley assembly 44 further transmits power, ensuring the stability and efficiency of the transmission. Through this design, the transmission efficiency between the drive motor 41 and the drive gear 42 is improved, and the lifting and lowering process of the socket body 2 is more stable and reliable. As a preferred embodiment, the reduction gearbox 43 can adopt a planetary gear structure, which has high transmission efficiency and compact size, suitable for use in limited spaces. The pulley assembly 44 can adopt a synchronous pulley, which has the characteristics of smooth transmission and low noise, and can further improve the stability of the transmission. Therefore, the technical solution of this application, through the combination of the reduction gearbox 43 and the pulley assembly 44, effectively solves the transmission efficiency problem between the drive motor 41 and the drive gear 42, ensuring that the socket body 2 can be raised and lowered smoothly. Compared with the prior art, the technical solution of this application has higher transmission efficiency and a more stable raising and lowering process, which can better meet the actual use needs.

[0038] like Figure 5 and 6 As shown, the rack 5 is fitted onto the outer wall of the socket housing 21; the drive assembly 4 is located inside the socket housing 21 of the socket body 2, with only the drive gear 42 of the drive assembly 4 protruding from the socket housing 21 and meshing with the rack 5. Specifically, the rack 5 is fitted onto the outer wall of the socket housing 21, making the structure of the rack 5 and the socket housing 21 more compact and reducing the space occupied. The drive assembly 4 is located inside the socket housing 21 of the socket body 2, with only the drive gear 42 of the drive assembly 4 protruding from the socket housing 21 and meshing with the rack 5. This design allows the drive assembly 4 to effectively mesh with the rack 5 while being installed internally, thereby realizing the lifting function of the socket body 2. Through this structural design, the stable operation of the drive assembly 4 is ensured, while avoiding the complexity of the external structure, improving the practicality and aesthetics of the overall device. Therefore, the technical solution of this application achieves a compact installation of the drive assembly 4 inside the socket housing 21 by fitting the rack 5 against the outer wall of the socket housing 21 and placing the drive assembly 4 inside the socket housing 21, with only the drive gear 42 partially exposed and meshing with the rack 5. This design not only simplifies the external structure but also improves the stability and practicality of the device, solving the technical problem of meshing the drive gear 42 with the rack 5 when the drive assembly 4 is installed inside the socket housing 21.

[0039] Furthermore, a sliding bracket 24 is provided on the outer wall of the socket housing 21, and the rack 5 is slidably mounted on the sliding bracket 24; when the socket body 2 moves relative to the cylindrical base 1, the sliding bracket 24 moves relative to the rack 5. The sliding bracket 24 allows the rack 5 to slide on the outer wall of the socket housing 21, so that when the socket body 2 moves relative to the cylindrical base 1, the sliding bracket 24 moves relative to the rack 5. This design ensures that the socket body 2 can move smoothly during lifting and lowering, and through the cooperation of the sliding bracket 24 and the rack 5, the precise positioning of the socket body 2 is achieved. The sliding cooperation between the sliding bracket 24 and the rack 5 not only guides the lifting and lowering but also improves the stability and accuracy of the lifting and lowering, solving the problems of unstable movement and inaccurate positioning of the socket body 2 in traditional designs. Therefore, the technical solution of this application achieves smooth movement and precise positioning of the socket body 2 during lifting and lowering through the sliding cooperation between the sliding bracket 24 and the rack 5. Compared with existing technologies, this solution not only solves the problems of unstable movement and inaccurate positioning of the socket body 2 in traditional designs, but also improves the stability and accuracy of lifting and lowering through the design of the sliding bracket 24, making the socket body 2 more reliable and efficient during the lifting and lowering process.

[0040] like Figures 4-6 As shown, the rack 5 is constructed in a T-shape or L-shape, and a stop bar 51 is constructed on the upper end of the rack 5. When the socket body 2 rises to its highest position relative to the cylindrical base 1, the stop bar 51 at the upper end of the rack 5 abuts against the sliding bracket 24. Specifically, the stop bar 51 at the upper end of the rack 5 abuts against the sliding bracket 24, which can limit the socket body 2 when it rises to its highest position, preventing the socket body 2 from rising further, thereby achieving precise positioning and preventing excessive movement. The cooperation between the stop bar 51 and the sliding bracket 24 ensures the stability and safety of the socket body 2 during the lifting process, avoiding equipment damage or inconvenience caused by excessive movement. As a preferred embodiment, the T-shaped or L-shaped structure of the rack 5 can be achieved by integral molding or separate assembly. In addition, the sliding bracket 24 can be designed with a structure with cushioning material to further reduce impact and noise. Therefore, this technical solution, through the T-shaped or L-shaped structure design of the rack 5 and the cooperation between the stop bar 51 and the sliding bracket 24, effectively solves the technical problem of the socket body 2 being unable to be accurately positioned and preventing excessive movement during the lifting and lowering process. Compared with the prior art, this solution not only improves the lifting accuracy and stability of the socket body 2, but also enhances the safety and lifespan of the equipment.

[0041] Furthermore, this application proposes that a lower limit switch 45 is also provided on the drive assembly 4. The lower limit switch 45 is exposed outside the socket housing 21 and located next to the sliding bracket 24. When the socket body 2 rises to its highest position relative to the cylindrical base 1, the stop bar 51 at the upper end of the rack 5 abuts against the lower limit switch 45, triggering the drive assembly 4 to stop. The lower limit switch 45 can be implemented in various ways. For example, the lower limit switch 45 can be a mechanical switch. When the stop bar 51 contacts the switch, mechanical force triggers the switch to operate, thereby cutting off the power supply to the drive motor 41. Another implementation is to use a photoelectric sensor as the lower limit switch 45. When the stop bar 51 blocks the light path of the photoelectric sensor, the sensor outputs a signal to control the drive motor 41 to stop. In addition, a magnetic sensor can also be used. A magnet is installed on the stop bar 51. When the stop bar 51 approaches the sensor, the sensor senses the change in magnetic field and outputs a signal to control the drive motor 41 to stop. Through the above technical means, this application solves the problem that the socket body 2 cannot automatically stop when it rises to its highest position. The lower limit switch 45 automatically stops the socket body 2 when it reaches its highest position, preventing mechanical damage or inconvenience caused by excessive descent. Specifically, when the socket body 2 rises to its highest position, the stop bar 51 at the upper end of the rack 5 abuts against the lower limit switch 45, triggering the drive assembly 4 to stop, thereby preventing the socket body 2 from continuing to descend. Compared with the prior art, the technical solution of this application has higher reliability and safety, and can effectively avoid equipment damage or inconvenience caused by excessive descent.

[0042] In addition, an upper limit switch 46 is provided at the upper end of the socket body 2. When the socket body 2 descends to its lowest position relative to the cylindrical base 1, the stop bar 51 at the upper end of the rack 5 directly or indirectly triggers the upper limit switch 46, thereby triggering the drive assembly 4 to stop. The upper limit switch 46 can be implemented in various ways. For example, the upper limit switch 46 can be a mechanical switch, which is triggered when the stop bar 51 at the upper end of the rack 5 contacts the switch, thereby sending a signal to the drive assembly 4 to stop it. Alternatively, the upper limit switch 46 can also be a photoelectric switch, which is triggered when the stop bar 51 blocks the light path of the photoelectric switch. Another implementation is to use a magnetic switch, with a magnet installed on the stop bar 51, which is triggered when the stop bar 51 approaches the magnetic switch. These implementations can effectively ensure that the socket body 2 automatically stops when it reaches the lowest position. This technical solution, by incorporating an upper limit switch 46, allows the stop bar 51 at the upper end of the rack 5 to directly or indirectly trigger the upper limit switch 46 when the socket body 2 descends to its lowest position, thereby stopping the drive assembly 4. This feature ensures that the socket body 2 automatically stops upon reaching its lowest position, preventing mechanical damage or electrical malfunctions caused by excessive descent. The upper limit switch 46 not only improves equipment safety but also enhances user convenience, making the lifting and lowering process of the socket body 2 more precise and reliable. Compared to existing technologies, this solution achieves automatic stopping through a simple mechanical structure, avoiding complex control systems and reducing manufacturing costs and maintenance difficulty.

[0043] In the specific design, the upper end of the socket body 2 is provided with an upper connecting cover 61; a circuit board 62 is installed inside the upper end of the upper connecting cover 61, and a control switch (not shown) is provided on the circuit board 62; the control switch is a push switch and is located in the middle of the upper end of the circuit board 62; the control switch is used to control the drive component 4 to start when it is pressed by external force. The upper end of the upper connecting cover 61 is provided with a pressure cover 64 for pressing the control switch; the lower end of the pressure cover 64 abuts against the button of the control switch located at the upper end; the upper limit switch 46 is connected to the lower end of the circuit board 62, and the upper connecting cover 61 is provided with a pressing block 65 that abuts against the upper limit switch 46. When the socket body 2 descends to the lowest position relative to the cylindrical base 1, the stop bar 51 at the upper end of the rack 5 triggers the upper limit switch 46 through the pressing block 65. Specifically, the design of the upper connecting cover 61 allows the circuit board 62 and the control switch to be securely installed inside it, thereby ensuring the stability of the entire control system. The control switch is a push-button switch located at the top center of the circuit board 62. This design makes the switch triggering more sensitive and accurate. The cover 64 not only protects the control switch but also provides precise control of the switch by abutting against the control switch button at its lower end. The upper limit switch 46 is connected to the lower end of the circuit board 62, and the upper connecting cover 61 has a pressing block 65 that abuts against the upper limit switch 46. This design allows the stop bar 51 at the upper end of the rack 5 to trigger the upper limit switch 46 through the pressing block 65 when the socket body 2 descends to its lowest position, thereby stopping the drive assembly 4.

[0044] Furthermore, the pressure cap 64 includes a cap body 641 and a decorative ring 642 disposed on the cap body 641; multiple downwardly extending insertion arms 643 are equidistantly formed on the outer periphery of the cap body 641, and each insertion arm 643 has a snap-fit ​​644 formed on its outer wall; a locking block 611 is disposed on the inner side wall of the upper connecting cover 61, and when the cap body 641 is closed on the upper connecting cover 61, the locking block 611 is engaged in the snap-fit ​​644; the circuit board 62 is disposed inside the upper connecting cover 61 below the cap body 641, and the circuit board 62 is elastically supported at the center of the cap body 641. Specifically, the design of the cap body 641, through the cooperation of multiple insertion arms 643 with the snap-fit ​​611 of the upper connecting cover 61, achieves a stable connection between the pressure cap 64 and the upper connecting cover 61. The engaging design of the snap-fit ​​644 on the insertion arms 643 and the snap-fit ​​611 ensures that the pressure cap 64 will not easily loosen or fall off when closed. Meanwhile, the circuit board 62 is elastically supported at the center of the cover 641, giving the cover 641 an elastic pressing effect and allowing it to spring back elastically when the external force is removed. This design not only improves the connection stability between the pressure cover 64 and the upper connecting cover 61, but also ensures the fixation of the circuit board 62, thereby improving the service life and safety of the entire socket. As a preferred embodiment, the number of plug arms 643 can be adjusted according to actual needs, for example, set to four or six, to enhance connection stability. The specific shapes of the latch 644 and the latch block 611 can also be designed as needed. In addition, the elastic support part of the cover 641 can be made of spring or elastic rubber material to provide better cushioning effect. Thus, the technical solution of this application effectively solves the problems of connection stability between the pressure cover 64 and the upper connecting cover 61 and the fixation of the circuit board 62 through the snap-fit ​​design of the pressure cover 64 and the upper connecting cover 61, and the elastic support of the cover 641 for the circuit board 62. Compared with existing technologies, this solution not only improves the reliability of the connection, but also reduces the displacement of the circuit board 62 caused by vibration or external force through the elastic support design, thereby improving the overall performance and service life of the socket.
