AI Technical Summary
The existing control boxes for construction machinery cannot easily adjust the lateral distance during the adjustment process, and lack protection for the lower part of the control box, which allows dust and other impurities to enter and affect the smoothness of transmission.
The operation seat is moved by the threaded engagement of the first and second screws, and the three-dimensional adjustment of the operation seat is achieved by the hydraulic cylinder. The shielding mechanism composed of the binding groove, top cover, and elastic rubber protective sleeve prevents dust from entering.
The control panel features convenient three-dimensional adjustment, improving operational comfort while preventing dust from entering and affecting transmission, thus ensuring the smoothness and cleanliness of the control box.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, and more specifically, to an adjustable control box for engineering machinery. Background Technology
[0002] Construction machinery is an important component of the equipment manufacturing industry. In general terms, construction machinery refers to the mechanical equipment necessary for comprehensive mechanized construction projects, including earthmoving, road construction and maintenance, mobile lifting and loading operations, and various building projects. The control room of construction machinery contains an operating panel for controlling the machinery.
[0003] A search revealed that utility model patent CN222834994U discloses a control box for engineering machinery, which includes a mounting frame and a lifting platform. An electric lifting rod is mounted on the top of the mounting frame, and the lifting platform is positioned at the top of the electric lifting rod. A groove is provided on the top of the lifting platform, and a screw is installed within the groove. A motor is mounted on the side wall of the lifting platform. This application document describes a control box for engineering machinery that allows for easy adjustment of the control box's position and height after installation, achieving adjustability. This allows drivers of different heights to adjust the position of the control handle according to their gripping needs, improving driver comfort. However, the above patent still has the following shortcomings: although the height and front and rear positions of the control box can be adjusted, it is not convenient to adjust the lateral distance between the control box and the operator. The ease of operation and suitability of the operator's control handle need to be improved. In addition, there is no protection for the adjustment mechanism at the bottom of the control box, and dust and other impurities can easily enter and affect the smoothness of adjustment. For example, dust adhering to the screw can affect the transmission between the screw and the slider. Therefore, we propose an adjustable control box for engineering machinery. Utility Model Content

Two second slide rods 12 are fixedly sleeved between the two second supports 8. The two second slide rods 12 are movably sleeved with the second slide block 10. The second slide block 10 is limited by the cooperation between the second slide rods 12 and the second slide block 10, so that the second slide block 10 can only move along the axial direction of the second screw 9. The bottom surface of the second slide block 10 is in contact with the top surface of the first slide block 5. The first slide block 5 supports the second slide block 10. Telescopic rods 16 are fixedly installed on the top surface of the second slide block 10 and on both sides of the hydraulic cylinder 13.

The top surface of the locking blocks 22 is in contact with the top surface of the inner cavity of the regulating box 1, and the outer surface of the inserts 21 is in contact with the inner wall of the movable groove 2. The locking blocks 22 secure the inserts 21 and the top cover 18 to the top of the regulating box 1, and the elasticity of the rubber ring 20 secures the rubber ring 20 to the operating seat 14. In the side binding groove 17, an elastic rubber protective sleeve 19 is used to shield the operating seat 14 and the adjustment box 1. Example 3
[0023] Based on Embodiments 1 and 2, as shown in Figures 1 to 3, the bottom of the regulating box 1 is provided with a pipeline through hole 24.

[0024] It should be noted that this utility model is an adjustable control box for engineering machinery. When it is necessary to adjust the position of the operating handle 25 above the operating seat 14, firstly, the first brake reduction motor 6 is started to drive the first screw 4 to rotate. Through the threaded engagement between the first screw 4 and the first slide 5, the first slide 5, the second support 8, the second slide 10, the hydraulic cylinder 13, and the operating seat 14 move back and forth. Then, the second brake reduction motor 11 is started to drive the second screw 9 to rotate. Through the threaded engagement between the second screw 9 and the second slide 10, the second slide 10, the hydraulic cylinder 13, and the operating seat 14 move laterally, adjusting the lateral distance between the operating handle 25 on the operating seat 14 and the operator. Then, the hydraulic cylinder 13 is started to drive the operating seat 14 to move up and down, thereby adjusting the height of the operating handle 25. Finally, the operator operates the operating handle 25 and the operating button 26 on the top of the operating seat 14 to control the engineering machinery.
