Description

Technical Field

[0001] This utility model relates to the field of transmission shaft technology for height-adjustable desks, and in particular to a high-strength transmission shaft for height-adjustable desks. Background Technology

[0002] With the modernization of office environments, height-adjustable desks are widely used in offices, schools, and homes due to their height-adjustable features. Currently, most height-adjustable desks on the market use electric or manual methods for height adjustment, and the drive shaft, as a key component, directly affects the stability and lifespan of the desk.

[0003] However, existing height-adjustable desk drive shafts generally suffer from insufficient strength, easy wear and tear with long-term use, and low transmission efficiency. This can cause the desk to vibrate, jam, or make abnormal noises during the lifting process, affecting the user experience. Especially under high-frequency or long-term use, the drive shaft is prone to damage due to material fatigue or overload, further reducing the stability and service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problems of insufficient strength and easy wear after long-term use in the existing technology, and to propose a high-strength lifting table drive shaft.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength lifting table drive shaft, comprising a central block, both ends of which are fixedly connected to connecting pipes, a fixing block fixedly connected to the center of the top and the center of the bottom of the central block, a reinforcing rod fixedly connected to both sides of the fixing block, a connecting flange fixedly connected to the outer surface of one end of the connecting pipe, and the outer edge of the connecting flange fixedly connected to one end of the reinforcing rod.

[0006] Preferably, a central rod is fixedly connected to the inner side of the connecting pipe.

[0007] Preferably, a bushing is fixedly connected to the side wall of the connecting flange.

[0008] Preferably, a sleeve is fixedly connected to one side of the bushing.

[0009] Preferably, one end of the central rod passes through the bushing and the sleeve.

[0010] Preferably, a connecting shaft is fixedly connected to the outer surface of one end of the central rod.

[0011] Preferably, one end of the connecting shaft is fixedly connected to one end of the sleeve, and a transmission wheel is fixedly connected to the outer surface of the sleeve.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the combination of reinforcing rod and fixing block greatly improves the overall rigidity of the lifting table transmission system, ensuring that the transmission shaft is not prone to bending or twisting deformation when subjected to external loads. Under long-term, high-load operating conditions, the transmission structure remains stable, ensuring the continuous operation of the lifting table. The tight cooperation between the fixing block and the reinforcing rod improves the connection strength and rigidity of the connecting flange, preventing loosening or falling off, and avoiding system failures caused by unstable connections.

[0014] 2. In this utility model, the application of the central rod not only effectively distributes the torque load when a large torque transmission is required, but also reduces the force on a single drive shaft, so that the torque is evenly distributed to the central rod and the connecting pipe. This design improves the overall load-bearing capacity of the system, reduces the risk of drive shaft damage or failure due to excessive torque, and ensures that the transmission system can still transmit power stably and reliably under high load conditions, reducing the possibility of failure. This improves the operational stability and safety of the mechanical system, and the enhanced stability not only extends the service life of the equipment. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1-3 As shown, this utility model provides a high-strength lifting table drive shaft, including a central block 1. Both ends of the central block 1 are fixedly connected to connecting pipes 5. Fixed blocks 6 are fixedly connected to the top center and bottom center of the central block 1. Reinforcing rods 4 are fixedly connected to both sides of the fixed blocks 6. A connecting flange 9 is fixedly connected to the outer surface of one end of the connecting pipe 5. The outer edge of the connecting flange 9 is fixedly connected to one end of the reinforcing rod 4.

[0023] The specific setup and function of this embodiment will be described in detail below. The combined use of the reinforcing rod 4 and the fixing block 6 greatly improves the overall rigidity of the lifting table's transmission system. This ensures that the transmission shaft can effectively prevent bending, twisting, and other deformation problems when subjected to external loads, thereby enhancing the system's stability and reliability. Under long-term, high-load usage conditions, the transmission shaft structure remains stable, extending its service life and ensuring the continuous operation of the lifting table during frequent use.

[0024] The tight fit between the fixing block 6 and the reinforcing rod 4 significantly improves the connection strength and rigidity of the connecting flange 9. By preventing loosening and detachment at the connection, system failures caused by unstable connections are avoided. During operation, the connections between various components of the lifting table are securely maintained, preventing power transmission interruptions or component damage due to connection failures, thereby ensuring the smooth operation of the production process and the long-term reliability of the equipment.

[0025] Furthermore, the design of transmission wheel 2 ensures that each axis maintains a consistent phase during lifting, thus coordinating each lifting action of the table and avoiding instability caused by phase mismatch. Each lifting operation is precisely synchronized, effectively improving the operating accuracy of the table and ensuring accurate height adjustment during operation.

[0026] Example 2: Figure 2 and Figure 3 As shown, a central rod 8 is fixedly connected to the inner side of the connecting pipe 5. A bushing 7 is fixedly connected to the side wall of the connecting flange 9. A sleeve 10 is fixedly connected to one side of the bushing 7. One end of the central rod 8 passes through the bushing 7 and the sleeve 10. A connecting shaft 3 is fixedly connected to the outer surface of one end of the central rod 8. One end of the connecting shaft 3 is fixedly connected to one end of the sleeve 10, and a transmission wheel 2 is fixedly connected to the outer surface of the sleeve 10.

[0027] The overall effect of this embodiment is that, in situations requiring large torque transmission, the central rod 8 not only shares the torque but also effectively reduces the load on a single drive shaft. By evenly distributing the torque to the central rod 8 and the connecting pipe 5, not only is the individual force reduced, improving the overall load-bearing capacity of the system, but the risk of drive shaft damage or failure due to excessive torque is also reduced.

[0028] This ensures that the lifting table's transmission system can reliably transmit power even under high-load operating conditions, reducing the possibility of malfunctions and thus improving the overall stability and safety of the mechanical system. This enhanced stability not only extends the service life of the production equipment but also significantly improves its economic efficiency and reduces maintenance and replacement costs.

[0029] The usage and working principle of this device: The combined use of the reinforcing rod 4 and the fixing block 6 can effectively improve the overall rigidity of the lifting table drive shaft, making it less prone to bending, twisting and other deformations when bearing loads. At the same time, it enhances the connection strength and rigidity between the shaft and the connecting flange 9, preventing loosening or falling off, and ensuring a stable and reliable connection during transmission, thereby avoiding power transmission interruption or component damage due to connection failure.

[0030] The transmission structure of drive wheel 2 ensures that the phases of each axis are consistent during movement. Each lifting action of the lifting table is coordinated and consistent, avoiding instability caused by phase mismatch.

[0031] A central rod 8 is provided inside the connecting pipe 5. When a large torque needs to be transmitted, the torque can be distributed to the two shafts, thereby reducing the stress on a single shaft and improving the load-bearing capacity of the entire transmission system. This design ensures stable and reliable power transmission under high-load conditions, avoiding damage to the drive shaft or transmission failure due to excessive torque.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
