Technical Field
[0001] This utility model belongs to the field of engineering machinery equipment and instrument technology, specifically relating to an angle-adjustable engineering machinery instrument. Background Technology
[0002] Construction machinery is an important component of the equipment manufacturing industry. In general, 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. It is mainly used in national defense construction, transportation construction, energy industry construction and production, mining and other raw material industry construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, and environmental protection. Currently, although existing construction vehicle dashboards can tilt forward and backward, their complex structure and unsatisfactory adjustment effects, along with issues such as steering wheel connection shaft rotation settling, wobbling, and lateral movement, affect the operational safety and reliability of construction vehicles.
[0003] Therefore, a control mechanism for an instrument panel of engineering machinery, with announcement number "CN208978623U", includes a fixed base and an operation panel. The fixed base has several locking bolts at its bottom. The upper side of the fixed base is connected to a steering wheel via a steering shaft. A guide sleeve is provided on one side of the fixed base, and a sliding rod is installed inside the guide sleeve. The upper end of the sliding rod is connected to the operation panel via a connector. A rotation damper is provided at the connection between the sliding rod and the connector. A screw is installed inside the sliding rod, and a driven gear is mounted on the screw. The driven gear meshes with a driving gear, and the driving gear is connected to an adjusting motor. This mechanism allows for height and fore-aft position adjustment according to the operator's working needs, greatly increasing the driver's comfort when operating the engineering vehicle, better meeting ergonomic requirements, preventing fatigue caused by long-term operation, and maintaining safe production.
[0004] However, for the aforementioned instrument panel control mechanism of construction machinery, although the drive gear and the adjusting motor are connected by a profile, allowing for height and forward / backward adjustment according to the operator's work needs, greatly increasing the driver's comfort when operating the construction vehicle, the following significant drawbacks still exist during use: The adjustment mechanism uses a motor-driven method to adjust the instrument's height. However, during the process of adjusting the instrument to the appropriate height, the motor's rotational inertia when it stops causes the instrument to continue moving up and down, easily leading to height adjustment errors. This necessitates repeated adjustments by the operator to achieve the desired height. Utility Model Content
[0005] The purpose of this invention is to provide an angle-adjustable engineering machinery instrument to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an angle-adjustable engineering machinery instrument, comprising:
[0007] The instrument body has a U-shaped instrument adjustment seat on one side via a rotating shaft for adjusting the angle of the instrument body. The instrument adjustment seat has evenly spaced angle positioning holes and slots on both inner side walls for positioning the instrument body after angle adjustment. The rotating shaft has a movable fixed rod with a threaded insert at one end outside the instrument adjustment seat.
[0008] A square column has a guide lifting rod in the inner cylindrical cavity of the square column for limiting and lifting to adjust the height of the instrument body. The bottom end of the guide lifting rod is threaded with a drive screw to drive the lifting rod to adjust its height. The bottom end of the square column is rotatably provided with a toothed foot plate that drives the drive screw to rotate using a foot.
[0009] Preferably, the square column has a cylindrical groove at its end, and guide grooves are provided on both sides of the inner wall of the cylindrical groove, and lifting guide blocks are provided in each guide groove.
[0010] Preferably, the guide lifting rod is movably inserted into the cylindrical groove and fixedly connected to the lifting guide block, and the bottom end of the guide lifting rod is provided with a threaded drive groove, and the upper end of the guide lifting rod is fixed to the outside of one side of the instrument adjustment seat.
[0011] Preferably, one end of the drive screw is threaded into the threaded drive groove at the bottom of the guide lifting rod, and the other end of the drive screw is mounted at the bottom of the cylindrical groove through a bearing seat. The lower end of the drive screw is fixed with drive teeth that mesh with the toothed foot plate, which reduces the height adjustment error and can more accurately adjust the instrument body to a suitable height.
[0012] Preferably, the bottom outer end of the square column has a movable groove that communicates with the cylindrical groove. The toothed foot plate is set in the movable groove through a shaft with bearing components, and one end of the toothed foot plate is located outside the square column, which avoids interference between the toothed foot plate and the square column and improves the reliability and service life of the entire adjustment mechanism.
[0013] Preferably, the square column has a fixed base at its bottom, and a steering shaft is provided on the upper inclined surface of the fixed base. An engineering machinery steering wheel is provided on the steering shaft. The fixed base also provides stable support for the entire instrument system, ensuring the stability and reliability of the instrument during vehicle operation.
[0014] Preferably, one end of the movable rod is threaded through a positioning insert, and the positioning insert is inserted into the angle positioning hole groove for positioning after the tilt angle of the instrument body is adjusted.
[0015] Compared with existing technologies, the technical effects and advantages of this utility model are as follows: This angle-adjustable engineering machinery instrument has its main body connected to a U-shaped instrument adjustment seat via a rotating shaft, allowing for flexible angle adjustment to meet the viewing angle needs of different drivers. Combined with the evenly distributed angle positioning holes and slots on both sides of the instrument adjustment seat, and the positioning insert on the movable rod, the angle can be precisely fixed after adjustment, preventing angle deviation due to vibration or other external forces, and ensuring stable display of instrument information.
[0016] By employing a manual height adjustment method, the toothed foot plate at the bottom of the square column is rotated by foot drive, which in turn drives the drive screw that meshes with it to rotate. The drive screw acts on the threaded drive groove of the guide lifting rod, allowing the guide lifting rod to rise and fall smoothly within the cylindrical cavity of the square column. This avoids height adjustment errors caused by motor drive inertia, and can accurately adjust the instrument body to the appropriate height in one go, saving adjustment time and effort.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Please see Figure 1-3 This utility model provides a technical solution: an angle-adjustable engineering machinery instrument, comprising:
[0023] The instrument body 1 has a U-shaped instrument adjustment seat 3 on one side, which is connected to a rotating shaft 2 for angle adjustment. The rotating shaft 2 allows the instrument body 1 to rotate flexibly relative to the instrument adjustment seat 3, achieving angle adjustment to meet different viewing angle requirements. The instrument adjustment seat 3 has evenly spaced angle positioning slots 4 on its inner two side walls for positioning the instrument body 1 after angle adjustment. The U-shaped structure of the instrument adjustment seat 3 is ingeniously designed, providing a stable mounting position for the instrument body 1 while reserving space for convenient angle adjustment. The angle positioning slots 4 on its inner two side walls are used to precisely fix the adjusted instrument angle. A movable fixed rod 5 with a threaded insert is located at one end of the rotating shaft 2 outside the instrument adjustment seat 3. After the instrument body 1 has completed angle adjustment, the angle positioning slots 4, in conjunction with the movable fixed rod 5 and the positioning insert 19, provide multiple discrete positioning points. The movable fixed rod 5 is installed at one end of the rotating shaft 2 and its position can be finely adjusted using the threaded insert structure, providing stable support for the positioning insert 19. When adjusting the instrument angle, it can be moved as needed to align with the appropriate angle positioning slot 4.
[0024] The square column 6 serves as the vertical support structure for the entire instrument unit. Its internal cylindrical cavity houses components such as the guide lifting rod 7, providing space for height adjustment and ensuring the overall structural vertical stability. The cylindrical cavity within the square column 6 contains the guide lifting rod 7, which adjusts the height of the instrument body 1. The guide lifting rod 7 is fixedly connected to the instrument adjustment seat 3, transmitting its own lifting motion to the instrument body 1 for height adjustment. It is also connected to the lifting guide block 12 within the cylindrical groove 10, allowing for stable lifting along the guide groove 11 and preventing swaying. The bottom of the guide lifting rod 7 has an internal threaded drive screw 8 for adjusting its height. When the toothed foot plate 9 rotates, the drive screw 8 rotates accordingly, using the threaded transmission principle to drive the guide lifting rod 7 up and down, precisely controlling the height of the instrument body 1. The square column 6 also has a toothed foot plate 9 that rotates through the bottom of the external part of the external part of the square column 6, allowing the operator to drive the drive screw 8 using their feet. The toothed foot plate 9 is partially exposed, allowing for easy foot operation by the operator.
[0025] The square column 6 has a cylindrical groove 10 inside its end, and guide grooves 11 are provided on both sides of the inner wall of the cylindrical groove 10. Each guide groove 11 is provided with a lifting guide block 12. The cylindrical groove 10 is opened inside the end of the square column 6 to provide installation space for components such as the guide lifting rod 7 and the drive screw 8. It works with the guide grooves 11 to ensure the smoothness and accuracy of the movement of each component. The guide grooves 11 are located on both sides of the inner wall of the cylindrical groove 10 and work with the lifting guide blocks 12 to guide and limit the lifting of the guide lifting rod 7.
[0026] The guide lifting rod 7 is movably inserted into the cylindrical groove 10 and fixedly connected to the lifting guide block 12. The bottom end of the guide lifting rod 7 is provided with a threaded drive groove 13. The upper end of the guide lifting rod 7 is fixed to the outside of one side of the instrument adjustment seat 3. The lifting guide block 12 is fixed on the guide lifting rod 7 and placed in the guide groove 11. It is a key component for the stable lifting of the guide lifting rod 7. It can bear the weight of the instrument body 1 and the guide lifting rod 7 itself and convert it into vertical sliding along the guide groove 11, avoiding unstable situations such as rotation and offset. The threaded drive groove 13 is set inside the bottom end of the guide lifting rod 7 and is precisely matched with the drive screw 8 to convert the rotational motion of the drive screw 8 into the linear lifting motion of the guide lifting rod 7.
[0027] One end of the drive screw 8 is threaded into the threaded drive groove 13 at the bottom of the guide lifting rod 7, and the other end of the drive screw 8 is installed at the bottom of the cylindrical groove 10 through a bearing seat. The lower end of the drive screw 8 is fixed with a drive tooth 14 that meshes with the toothed foot plate 9. The drive tooth 14 is fixed at the lower end of the drive screw 8 and meshes tightly with the toothed foot plate 9. It is responsible for transmitting the rotational torque of the toothed foot plate 9, ensuring the continuity and stability of power transmission, and thus stably driving the guide lifting rod 7 to rise and fall.
[0028] The square column 6 has a movable groove 15 at its outer bottom end that communicates with the cylindrical groove 10. The toothed foot plate 9 is set in the movable groove 15 by a shaft with bearing components, and one end of the toothed foot plate 9 is located outside the square column 6. The movable groove 15 is opened at the outer bottom end of the square column 6 and communicates with the cylindrical groove 10, providing rotation space for the toothed foot plate 9. The shaft mounting method of the bearing components makes the toothed foot plate 9 rotate more smoothly and reduces friction loss.
[0029] The square column 6 has a fixed base 16 at its bottom, and a steering shaft 17 is provided on the upper inclined surface of the fixed base 16. An engineering machinery steering wheel 18 is provided on the steering shaft 17. One end of the movable fixed rod 5 is threaded through with a positioning insert 19, and the positioning insert 19 is inserted into the angle positioning hole slot 4 for positioning after the tilt angle of the instrument body 1 is adjusted.
[0030] Specifically, in use, the instrument body 1 is connected to the U-shaped instrument adjustment seat 3 via the rotating shaft 2, allowing it to rotate flexibly relative to the shaft. To adjust the angle, the instrument body 1 is rotated to the desired viewing angle. The instrument adjustment seat 3 has angle positioning slots 4 on both inner side walls. A movable fixed rod 5 at one end of the rotating shaft 2 is paired with a positioning insert 19. The movable fixed rod 5 is finely adjusted using a threaded insert structure, aligning the positioning insert 19 with the corresponding angle positioning slot 4, thus achieving precise positioning of the adjusted instrument angle to meet different viewing angle requirements. A square column 6 serves as a vertical support structure, with an internal cylindrical cavity housing components such as the guide lifting rod 7. The guide lifting rod 7 is fixed to the instrument adjustment seat 3, and its bottom end has a threaded drive groove 13 that precisely engages with the drive screw 8. One end of the drive screw 8 is placed in the threaded drive groove 13, and the other end is mounted on the bottom end of the cylindrical groove 10 via a bearing seat, with a drive tooth 14 fixed at the lower end. The toothed foot plate 9 is located on the outer bottom of the square column 6, partially exposed. The operator rotates the toothed foot plate 9 with their foot, which drives the drive screw 8 to rotate via the drive teeth 14. Utilizing the principle of threaded transmission, the guide lifting rod 7 is driven to rise and fall stably along the guide grooves 11 on both sides of the inner wall of the cylindrical groove 10, thereby achieving height adjustment of the instrument body 1. In addition, a fixed base 16 is provided at the bottom of the square column 6, and a steering wheel 18 for engineering machinery is installed on the steering shaft 17 on the upper inclined surface.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
