[0002] As a closed device that provides a specific gas environment (such as inert gas), the glove box is widely used in scenarios such as air-sensitive material processing, semiconductor manufacturing, chemical synthesis, and battery research and development. The glove box is usually equipped with a carrying platform inside for placing various experimental items, reaction vessels or workpieces to be processed. Its performance directly affects the quality and efficiency of experiments and production.

[0003] In vacuum glove box-related experiments and production operations, flexible operation of experimental items placed in the glove box is crucial. However, the existing vacuum glove box carrier has a single adjustment angle and can only be adjusted horizontally and rotated, and cannot achieve flexible adjustment at multiple angles. This makes it difficult for operators to accurately control the posture of experimental items that need to be placed or operated at specific angles, greatly limiting the feasibility and convenience of the experiment, reducing work efficiency, and may even affect the accuracy of the experimental results.

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Refer to the attached Figure 1-8 The cross hinge 23 is connected to the U-shaped support frame 22 so that the cross hinge 23 can rotate relative to the U-shaped support frame 22. Two symmetrical ends of the cross hinge 23 are rotatably connected to the U-shaped support frame 22, and the other two symmetrical ends are rotatably connected to the frame 24 so that the frame 24 can rotate relative to the cross hinge 23. A carrying platform 26 is installed on the top of the frame 24 through a mounting bracket 25 for placing experimental items. The cross hinge 23 cooperates with the U-shaped support frame 22 and the frame 24 to facilitate multi-angle adjustment of the carrying platform 26, so as to improve the flexibility and convenience of operating practical items.

[0033] An adjustment unit is provided at the bottom of one side of the frame 24, and the adjustment unit is extended and retracted to control the tilt angle of the frame 24. One end of the cross hinge shaft 23 passes through the frame 24, and an adjustment unit is provided at the bottom of the passing end. The adjustment unit is extended and retracted to adjust the tilt angle of the cross hinge shaft 23. The adjustment unit below the frame 24 is adjusted to rotate the frame 24 relative to the cross hinge shaft 23. The adjustment unit at the end of the cross hinge shaft 23 can rotate the cross hinge shaft 23 relative to the U-shaped support frame 22. The rotation directions of the two adjustment units are perpendicular to each other and will not interfere with each other's rotation, thereby ensuring the stability and reliability of the operation of the entire mechanism and ensuring flexible adjustment of the carrying platform 26.

[0034] A rotating table 21 is provided below the U-shaped support frame 22, and the adjustment units connected to the frame 24 and the end of the cross hinge shaft 23 are all provided above the U-shaped support frame 22 to enable the entire carrying unit to rotate along with the rotating table 21. This layout enables the entire carrying unit to rotate along with the rotating table 21, and will not interfere with the use of the adjustment unit when the carrying platform 26 is adjusted to rotate horizontally.

[0035] When the handle 271 is turned, the screw 273 is rotated to move relative to the bottom of the frame 24, and the screw 273 is rotated to move relative to the bottom of the frame 24.

[0036] A rotating rod 3 that penetrates the top plate of the bracket 1 is provided at the bottom of the rotating table 21. The rotating rod 3 passes through the main body of the glove box and is sealed to prevent the main body of the glove box from communicating with the outside air. The sealing treatment belongs to the existing technology in this field and will not be described in detail in this application.

[0037] The outer wall of the rotating rod 3 extending to the inside of the bracket 1 is provided with a transmission unit, which includes a rotating column 41 fixed to the outer wall of the rotating rod 3. The outer wall of the rotating column 41 is axially opened with a guide groove 42 that spirally extends along the surface of the column at a preset inclination angle. A rotatable pedal unit is provided inside the bracket 1. The pedal unit includes an insertion rod 55 inserted into the guide groove 42, so that the pedal unit and the transmission unit form a lever-type rotation fit. When the pedal unit rotates, the insertion rod 55 moves along the inside of the guide groove 42 to drive the rotating column 41 and the rotating rod 3 to rotate, so that the vertical movement of the pedal unit can be converted into the rotating column 41. and the rotational movement of the rotating rod 3. When the staff needs to rotate the carrying unit horizontally, they can directly step down on the front end of the pedal unit with their feet, so that the insertion rod 55 at the rear end moves upward along the guide groove 42. During this movement, the insertion rod 55 will apply a force to the rotating column 41 to make it rotate, thereby causing the rotating rod 3 and the rotating table 21 to rotate around the axis of the rotating rod 3, making it easy for the staff to rotate and adjust the carrying platform 26 through simple foot operations, greatly facilitating the operation of other directions of the experimental items on the top of the carrying unit, and no manual operation is required, which can avoid the risk of contamination caused by manual operation.

[0038] In this embodiment, the pedal unit includes a pedal arm 51 rotated on the bracket 1, the front end of the pedal arm 51 is provided with a foot pedal 52, and the rear end is provided with a pull rod 53, and the end of the pull rod 53 is connected to the insertion rod 55 through the pull arm 54. The operator drives the pedal arm 51 to rotate by stepping on the foot pedal 52, so that the pull rod 53 at the rear end drives the insertion rod 55 to move upward through the pull arm 54, and then the rotating column 41 drives the carrying unit to rotate through the rotating rod 3, thereby improving the convenience and efficiency of operation.

[0039] In this embodiment, a support plate 6 is provided in the bracket 1, and the pedal arm 51 is rotatably connected to the top of the support plate 6. The support plate 6 is provided with a through slot 7 at the rear end of the pedal arm 51 so that the pedal arm 51 has a larger displacement distance. When the pedal unit and the transmission unit are reset, the front end of the pedal unit is lifted so that the rear end of the pedal unit moves downward. During this process, the through slot 7 will not hinder the rear end of the pedal unit, which facilitates the reset of the pedal unit and the transmission unit and can ensure the stability of the entire device.

[0040] The reset push rod 84 is located below the foot pedal 51, so that when the reset pedal 82 is stepped on, the front end of the foot arm 51 moves upward. When the carrying unit needs to be horizontally rotated and reset, the operator steps on the reset pedal 82 downward. At this time, the rotating shaft 81 rotates accordingly, and drives the reset arm 83 and the reset push rod 84 to move upward. At this time, the reset push rod 84 pushes the front end of the foot arm 51, so that the rear end of the foot arm 51 moves downward, and then drives the insertion rod 55 to move in the opposite direction in the guide groove 42, so that the rotating column 41 and the rotating rod 3 rotate in the opposite direction, and finally the carrying unit returns to its initial position. The setting of the reset unit makes the operation more flexible and convenient, and the operator can reset the carrying platform 26 in the horizontal rotation direction at any time as needed.

[0041] In this embodiment, the guide groove 42 and the insertion rod 55 are arranged in pairs to improve the stability of the transmission, and vertical grooves 43 are provided at the upper and lower ends of the guide groove 42, which can effectively prevent the insertion rod 55 from being separated from the guide groove 42 due to excessive force when stepping on the pedal 52, thereby ensuring stability and safety during the transmission process.

[0042] In this embodiment, anti-skid grooves are provided on the tops of the foot pedal 52 and the reset pedal 82. The provision of the anti-skid grooves can increase the friction between the foot and the pedal, preventing the operator from slipping when stepping on the pedal, thereby improving the safety and stability of the operation.
