Description

Technical Field

[0001] This utility model relates to the field of workbench technology, specifically a workbench that is easy to lift and lower. Background Technology

[0002] A workbench is a platform for centralized management and processing of work tasks. It provides a convenient place to organize, schedule, and follow up on work, enabling users to effectively manage their time and tasks. Simultaneously, the workbench is also a flat surface for various operations, processing, experiments, or maintenance, designed to meet specific work requirements.

[0003] The existing workbench lacks a mechanism to ensure synchronization between the two sides during lifting. If the left and right sides fail to maintain synchronization during lifting, the workbench may tilt, which not only affects its normal use but also causes inconvenience to the staff. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a worktable that is easy to lift and lower, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a workbench that is easy to lift and lower, comprising a fixed frame, an upper seat fixedly connected to the top of the fixed frame, a lifting mechanism being provided on the top of the upper seat, and a rotating mechanism being provided inside the lifting mechanism;

[0006] The lifting mechanism includes a rectangular plate, which is fixedly connected to the top of the upper seat. A connecting shaft is rotatably connected to the inner side of the rectangular plate. A coupling is fixedly connected to the middle of the outer periphery of the connecting shaft. A synchronous gear is fixedly connected to the outer periphery of the connecting shaft. A synchronous rack meshes with the outer side of the synchronous gear. A rotating shaft housing is fixedly connected to the bottom of the synchronous rack. A slide rail is slidably connected to the outer periphery of the rotating shaft housing. The slide rail is fixedly connected to the inner side of the fixed frame. A seated bearing is rotatably connected to the outer periphery of the connecting shaft. The seated bearing is fixedly connected to the top of the upper seat. A lifting drive cylinder is fixedly connected to the middle of the top of the rotating shaft housing. The lifting drive cylinder is fixedly connected to the top of the upper seat.

[0007] Preferably, the upper seat has a rectangular groove inside that corresponds to the movement trajectory of the synchronous rack, and the synchronous rack is slidably connected inside the rectangular groove. The rectangular groove allows the synchronous rack to slide inside the upper seat.

[0008] Preferably, there are four synchronous racks, which are slidably connected to the inside of the upper seat, and synchronous gears mesh on the outer sides of the four synchronous racks. When the lifting speed on one side of the worktable is slow, the synchronous rack on that side experiences greater force, which is transmitted to the other side through the synchronous shaft. Since the oil circuits of the lifting cylinders on both sides are connected, the servo control valve on the oil circuit system is used to adjust and achieve balance and synchronization on both sides.

[0009] Preferably, the lifting mechanism includes a rotary drive cylinder, which is fixedly connected to the top front of the rotating shaft housing. A drive rack is fixedly connected to the bottom of the rotary drive cylinder, and a rotary gear meshes with the back end of the drive rack. A linkage shaft is fixedly connected inside the rotary gear, and the linkage shaft is rotatably connected to the inside of the rotating shaft housing. A worktable is fixedly connected to the left side of the linkage shaft.

[0010] Preferably, the shaft housing has a groove inside that corresponds to the movement trajectory of the drive rack, and the drive rack is slidably connected inside the groove. The groove allows the drive rack to slide inside the shaft housing.

[0011] Compared with the prior art, this utility model provides a worktable that is easy to lift and lower, and has the following beneficial effects:

[0012] 1. This easy-to-lift worktable, through its lifting mechanism, allows for height adjustment by using a lifting drive cylinder to move the rotating shaft housing upwards. This upward movement of the rotating shaft housing, in turn, moves the synchronous rack upwards, causing it to drive the synchronous gears. When the lifting speed on one side of the worktable is slower, the synchronous rack on that side experiences greater force, which is transmitted to the other side via the synchronous shaft. Since the hydraulic circuits of the lifting cylinders on both sides are connected, the servo control valve on the hydraulic circuit system adjusts the system to achieve balanced synchronization on both sides.

[0013] 2. This easy-to-lift worktable, through its rotating mechanism, allows for angle adjustment by rotating the drive cylinder to move the drive rack downwards, which in turn drives the rotating gear to rotate. The rotating gear then drives the worktable to rotate via the linkage shaft, thus allowing the worktable angle to be adjusted. Attached Figure Description

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.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0022] This utility model provides the following technical solution:

[0023] Example 1

[0024] Please see Figure 1-4 The present invention provides a technical solution: a workbench 23 that is easy to lift and lower, including a fixed frame 1, an upper seat 4 fixedly connected to the top of the fixed frame 1, a lifting mechanism 3 provided on the top of the upper seat 4, and a rotating mechanism 2 provided on the inner side of the lifting mechanism 3;

[0025] The lifting mechanism 3 includes a rectangular plate 35, which is fixedly connected to the top of the upper seat 4. A connecting shaft 33 is rotatably connected to the inner side of the rectangular plate 35. A coupling 39 is fixedly connected to the middle of the outer side of the connecting shaft 33. A synchronous gear 34 is fixedly connected to the outer side of the connecting shaft 33. A synchronous rack 37 meshes with the outer side of the synchronous gear 34. A rotating shaft housing 32 is fixedly connected to the bottom of the synchronous rack 37. A slide rail 31 is slidably connected to the outer side of the rotating shaft housing 32. The slide rail 31 is fixedly connected to the inner side of the fixed frame 1. A seated bearing 38 is rotatably connected to the outer side of the connecting shaft 33. The seated bearing 38 is fixedly connected to the top of the upper seat 4. A lifting drive cylinder 36 is fixedly connected to the middle of the top of the rotating shaft housing 32. The lifting drive cylinder 36 is fixedly connected to the top of the upper seat 4.

[0026] Furthermore, the upper seat 4 has a rectangular groove inside that corresponds to the movement trajectory of the synchronous rack 37, and the synchronous rack 37 is slidably connected inside the rectangular groove. Through the rectangular groove, the synchronous rack 37 can slide inside the upper seat 4.

[0027] Furthermore, there are four synchronous racks 37, which are slidably connected to the inside of the upper seat 4. Synchronous gears 34 mesh on the outer sides of the four synchronous racks 37. When the lifting speed on one side of the worktable 23 is slow, the synchronous rack 37 on that side experiences greater force, which is transmitted to the other side through the connecting shaft 33. The oil circuits of the lifting drive cylinders 36 on both sides are connected and are adjusted by the servo control valve on the oil circuit system to achieve balance and synchronization on both sides.

[0028] Example 2

[0029] Please see Figure 1-4 Furthermore, based on Embodiment 1, the lifting mechanism 3 further includes a rotary drive cylinder 24, which is fixedly connected to the top front of the rotating shaft housing 32. A drive rack 21 is fixedly connected to the bottom of the rotary drive cylinder 24. A rotary gear 25 is meshed at the back end of the drive rack 21. A linkage shaft 22 is fixedly connected inside the rotary gear 25. The linkage shaft 22 is rotatably connected to the inside of the rotating shaft housing 32. A worktable 23 is fixedly connected to the left side of the linkage shaft 22.

[0030] Furthermore, the shaft housing 32 has a groove inside that corresponds to the movement trajectory of the drive rack 21, and the drive rack 21 is slidably connected inside the groove. Through the groove, the drive rack 21 can slide inside the shaft housing 32.

[0031] In actual operation, when this device is used and the height of the worktable 23 needs to be adjusted, the lifting drive cylinder 36 drives the rotating shaft housing 32 to move upward. When the rotating shaft housing 32 moves upward, it can drive the synchronous rack 37 to move upward, so that the synchronous rack 37 can drive the synchronous gear 34 to rotate. When the lifting speed on one side of the worktable 23 is slow, the synchronous rack 37 on that side is subjected to greater force, which is transmitted to the other side through the connecting shaft 33. The oil circuits of the lifting drive cylinders 36 on both sides are connected, and the servo control valve on the oil circuit system is used to adjust to achieve balance and synchronization on both sides.

[0032] When the angle of the worktable 23 needs to be adjusted, the drive rack 21 is moved downward by the rotary drive cylinder 24, so that the drive rack 21 can drive the rotary gear 25 to rotate, and the rotary gear 25 can drive the worktable 23 to rotate through the linkage shaft 22, so that the angle of the worktable 23 can be adjusted.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
