Description

Technical Field

[0001] This utility model relates to the field of forklifts, specifically an electrically adjustable control panel structure. Background Technology

[0002] Forklifts are the main force in transportation operations, possessing basic functions such as loading, unloading, handling, and stacking. In order to accommodate the needs of drivers of different heights, the support structure of the existing forklift operating platform generally adopts a multi-pillar connection method. Through built-in adjustment devices, such as sliding grooves and retractable gas springs, the relative vertical and horizontal adjustment between the pillars can be realized, thereby achieving the adjustment of the operating platform.

[0003] However, existing control panel adjustment devices generally use mechanical braking to move the control panel relative to the support by opening the height adjustment knob or compressing the gas spring. However, manually pressing to unlock the control panel adjustment device is quite laborious in practice. As the control panel is used for many years, the natural wear and tear of mechanical parts makes the manual pressing less flexible. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical problem this invention aims to solve is to provide an electrically adjustable operating table structure that enables height and angle adjustment. In the angle adjustment device, an electromagnetic lock controls the unlocking and locking of a gas spring. Utilizing the self-locking and telescopic properties of the gas spring, the operating table, upper connecting column, and middle connecting column can be adjusted forward and backward relative to the lower connecting column. Simultaneously, the original mechanical adjustment is retained, ensuring that angle adjustment of the operating table is still possible even in the event of a power outage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An electrically adjustable control panel structure includes: The control panel is located on the upper connecting pipe column; The upper connecting pipe is sleeved outside the middle connecting pipe and can slide up and down relative to the middle connecting pipe; the middle connecting pipe and the lower connecting pipe are rotatably connected. An electric angle adjustment device is installed inside the lower connecting pipe column to adjust the relative angle between the middle connecting pipe column and the lower connecting pipe column.

[0006] The control panel is fixedly connected to the upper connecting column by multiple bolts. Various instruments, operation buttons, and function buttons such as control electromagnetic lock switches are arranged on it.

[0007] An opening is provided on one side of the middle connecting column; a pair of sliding pairs are provided between the upper connecting column and the middle connecting column, one end of the sliding pair is fixedly provided on one side of the inner wall of the upper connecting column, and the other end of the sliding pair is provided on the middle connecting column, and the upper connecting column and the middle connecting column slide relative to each other up and down through the sliding pair.

[0008] The upper connecting column is provided with a screw rod, and a mounting hole is provided on one side plate of the upper connecting column. A waist-shaped elongated hole is provided on one side plate of the middle connecting column along its height direction. A height adjustment handle is provided at one end of the screw rod. The screw rod passes through the mounting hole and the waist-shaped elongated hole and is connected to the height adjustment handle. The sliding stroke of the upper connecting column and the middle connecting column is limited by the position and length of the waist-shaped elongated hole provided on the middle connecting column.

[0009] The middle connecting column has a pivot hole on each of its bottom two sides, and the lower connecting column has a pivot hole on each of its top two sides. The connecting shaft passes through the pivot holes to connect the middle connecting column and the lower connecting column. Attached Figure Description

[0012] The technical solutions in specific embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] Example 1 Embodiment 1 provides an electrically adjustable control panel structure, relating to the field of forklifts. For example... Figure 1 As shown, it includes an operating table 1, an upper connecting column 2, a middle connecting column 4, and a lower connecting column 6.

[0014] Operating platform 1 is fixedly mounted on the upper connecting column 2 and connected by bolts.

[0015] The upper connecting pipe is sleeved outside the middle connecting pipe, such as Figure 2 As shown, the middle connecting column 4 has an opening on one side, and the upper connecting column 2 is sleeved on the middle connecting column 4; two slider sleeves are respectively provided at both ends of the opening side of the middle connecting column 4, and a slider structure is provided on the inner side of the upper connecting column corresponding to the opening side of the middle connecting column 4, so that the upper connecting column 2 and the middle connecting column 4 can slide up and down relative to each other through the slider structure connected by them.

[0016] In addition, one side plate of the upper connecting column 2 is provided with a mounting hole 21, and one side plate of the middle connecting column 4 is provided with a corresponding waist-shaped elongated hole 41 along its height direction. The outer side of the upper connecting column 2 is provided with a height adjustment handle 3 and a locking assembly. The locking assembly is a locking bolt assembly connecting the upper connecting column 2 and the middle connecting column 4, including a screw 8 and a nut located inside the height adjustment handle 3. The locking and releasing of the upper connecting column and the middle connecting column are achieved by adjusting the fit of the locking bolt assembly. Specifically, the outer side of the upper connecting column 2 is provided with a screw 8 and a height adjustment handle 3. One end of the screw 8 is threaded, and a nut is located inside the height adjustment handle 3. The screw 8 passes through the mounting hole 21 and the waist-shaped elongated hole 41 and connects to the height adjustment handle 3.

[0017] The lower connecting column 6 has an upward opening along the opening side of the middle connecting column 4; the bottom of the middle connecting column 4 has a pivot hole on each side, and the top of the lower connecting column 6 has a pivot hole on each side. The connecting pivot 5 passes through the pivot hole to connect the middle connecting column 4 and the lower connecting column 6, and can move back and forth. The lower connecting column 6 is equipped with a gas spring 9 and a return spring 10. Specifically, as shown... Figure 3 As shown, a connecting plate is formed at the bottom of the middle connecting column 4 and the bottom of the lower connecting column 6. Each of the two connecting plates has a through hole, through which the horizontal shaft passes. The gas spring 9 and the return spring 10 are fixedly connected to the two ends of the horizontal shaft, respectively.

[0018] The bottom of the lower connecting column is equipped with an electromagnetic lock 7 and a mechanical push rod 11. The gas spring 9 has a self-locking function and a telescopic adjustment function. By opening the electromagnetic lock or pushing the mechanical push rod 11, the position of the gas spring can be unlocked and locked to ensure that the position of the front and rear adjustment of the operating table is fixed.

[0019] The specific adjustment method is as follows: rotate the height adjustment handle 3 to loosen the upper connecting column 2 and the middle connecting column 4, so that the upper connecting column 2 and the middle connecting column 4 can slide up and down relative to each other through the slider structure they are connected to. When adjusted to a certain position, lock the height adjustment handle 3, and the upper connecting column 2 and the middle connecting column 4 will be pressed together. At this time, their relative height cannot be adjusted.

[0020] When the forklift is powered on, pressing the electromagnetic lock switch on the control panel 1 retracts the electromagnetic lock 7 push rod and pulls to open the gas spring lock. At this time, pushing the control panel 1 allows the control panel 1, upper connecting column 2, and middle connecting column 4 to rotate around the pivot 5 relative to the lower connecting column 6 to adjust the angle. When the position is adjusted to the appropriate position, releasing the electromagnetic lock switch locks the gas spring 9. When the forklift is not powered on, manually pushing the mechanical push rod 11 upwards releases the gas spring lock. Pushing the top control panel 1 allows the control panel 1, upper connecting column 2, and middle connecting column 4 to rotate around the pivot 5 relative to the lower connecting column 6, adjusting their angles. The angle adjustment range is controlled by the mechanical structure between the middle connecting column 4 and the lower connecting column 6. Once the desired position is achieved, releasing the mechanical push rod 11 locks the gas spring 9, and the control panel position becomes unadjustable.

[0021] In this solution, the control panel can be adjusted in height and angle, while retaining the mechanical adjustment method. The control panel can still be adjusted in the event of a power failure, which can meet the driver's preference settings for operating posture and operating habits. The adjustment process is more convenient, the overall operation is more stable, and it is more comfortable.

[0022] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
