Description

Technical Field

[0001] This utility model relates to the field of control instrument technology, and in particular to an engineering machinery instrument panel with an anti-accidental touch structure. Background Technology

[0002] Construction machinery instruments are mainly used to monitor the equipment's operating status in real time, display various parameters, and assist operators in controlling the construction machinery. They can help operators keep abreast of the equipment's operating conditions, detect abnormalities in a timely manner, and adjust operations as needed.

[0003] In the operating environment of engineering machinery instruments, their operational safety and reliability directly affect the equipment's operating efficiency and operational safety. Traditional fixed protective panels can only be opened in one direction, making it difficult to adjust the opening direction for some compact operating cabins and adapt to different equipment operating space layouts. In addition, some protective panels use a spring reset structure with a fixed reset speed and lack of buffer control. Rapid reset can easily damage components due to impact. At the same time, it is impossible to adjust the reset speed of the protective panel according to actual operating needs. Utility Model Content

[0004] The purpose of this utility model is to provide an engineering machinery instrument panel with an anti-accidental touch structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An engineering machinery instrument panel with an anti-accidental touch structure includes a control instrument. A cantilever bracket is fixedly installed on the rear side of the control instrument. A protective panel is movably installed on the front side of the control instrument. A U-shaped side plate is fixedly installed on the rear side of the protective panel. Slider blocks are fixedly installed on both sides of the U-shaped side plate. A countersunk hole is opened in the slider. An adjusting screw is threaded into the countersunk hole. A base is inserted into the countersunk hole near the adjusting screw. A damping ball is rotatably installed in the base.

[0007] As a further preferred embodiment of this utility model, the control instrument is provided with sliding grooves on both sides, and slots are provided at the top and bottom of the sliding grooves. A guide shaft is threaded between the two slots, and a compression spring is fitted on the outside of the guide shaft. The sliding grooves can provide conditions for the radial sliding of the slider, while the guide shaft can ensure the radial extension and retraction of the slider and the spring at the top or bottom of the sliding groove.

[0008] As a further preferred embodiment of this utility model, an operating handle is fixedly installed at the bottom of the U-shaped side plate. By manually pulling the operating handle, the protective panel can be moved vertically and radially in front of the control instrument, thereby exposing the operating area in front of the control instrument.

[0009] As a further preferred embodiment of this utility model, two guide slopes are provided on one side of the slider. Providing two slopes on one side of the slider facilitates the slider's sliding connection to the corresponding groove by utilizing the material toughness of the U-shaped side plate.

[0010] As a further preferred embodiment of this utility model, limit plugs are fixedly installed at the top and bottom of the slider, and through shaft holes are opened in the slider and the limit plugs. The shaft holes are connected to the adjusting screw cavity, and the shaft holes are also inserted into one of the guide shafts.

[0011] As a further preferred embodiment of this utility model, a compression spring is inserted and installed in the countersunk hole between the adjusting screw and the base.

[0012] As a further preferred embodiment of this utility model, the outer surface of the damping ball is coated with a rubber layer. The adjustment screw, base, damping ball, and spring between the adjustment screw and the base are arranged so that the damping ball abuts against the outside of the guide shaft, thereby providing damping for the reset of the protective panel. At the same time, the compression degree of the compression spring in the countersunk hole can be adjusted with the adjustment screw, thereby adjusting the abutment pressure of the damping ball against the guide shaft and controlling the reset speed of the protective panel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this utility model, the protective panel on the front of the control instrument can protect the control instrument operation area and prevent accidental touch. In addition, the protective panel can be adjusted to open from the top or the bottom. The opening direction can be adjusted according to the operating space of the construction machinery and the operating habits of the personnel, thereby improving the convenience of operation and space utilization.

[0015] In this invention, the reset damping of the protective panel is adjusted by regulating the contact pressure of the damping ball against the guide shaft. This allows for precise control of the reset speed of the protective panel, preventing excessively fast resets from causing impacts and protecting the control instruments and the protective panel itself. Furthermore, the damping magnitude can be flexibly adjusted according to actual operational needs, ensuring stable operation in scenarios requiring either rapid or slow resets. This enhances the safety and reliability of equipment operation and better meets the usage requirements under different working conditions. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-7 As shown, the present invention provides an engineering machinery instrument panel with an anti-accidental touch structure, including a control instrument 1, a cantilever bracket 2 fixedly installed on the rear side of the control instrument 1, a protective panel 3 movably installed on the front side of the control instrument 1, a U-shaped side plate 4 fixedly installed on the rear side of the protective panel 3, sliders 5 fixedly installed on both sides of the U-shaped side plate 4, a countersunk hole 6 opened in the slider 5, an adjusting screw 7 threadedly connected in the countersunk hole 6, a base 8 inserted in the countersunk hole 6 near the adjusting screw 7, and a damping ball 9 rotatably installed in the base 8.

[0026] like Figure 1 , Figure 3 As shown, an operating handle 15 is fixedly installed at the bottom of the U-shaped side panel 4. By manually pulling the operating handle 15, the protective panel 3 can be moved vertically and radially in front of the control instrument 1, thereby exposing the operating area in front of the control instrument 1.

[0027] like Figures 3-7As shown, the control instrument 1 has slide grooves 10 on both sides. Each slide groove 10 has a slot 11 at the top and bottom, and a guide shaft 12 is threaded between the two slots 11. A compression spring is fitted on the outside of the guide shaft 12. The slide groove 10 provides conditions for the radial sliding of the slider 5, while the guide shaft 12 ensures the radial extension and contraction of the slider 5 and the spring at the top or bottom of the slide groove 10. Two guide slopes are provided on one side of the slider 5. Providing two slopes on one side of the slider 5 facilitates the slider 5's sliding connection to the corresponding slide groove 10 using the material flexibility of the U-shaped side plate 4. Limiting plugs 13 are fixedly installed at the top and bottom of the slider 5. The slider 5 and the limiting plugs 13... A through-hole 14 is provided, and the through-hole 14 communicates with the cavity of the adjusting screw 7. The through-hole 14 is also inserted on one of the guide shafts 12. A compression spring is installed in the countersunk hole 6 between the adjusting screw 7 and the base 8. The outer surface of the damping ball 9 is coated with a rubber layer. The arrangement of the adjusting screw 7, the base 8, the damping ball 9, and the spring between the adjusting screw 7 and the base 8 allows the damping ball 9 to abut against the outside of the guide shaft 12, thereby providing damping for the reset of the protective panel 3. At the same time, the compression degree of the compression spring in the countersunk hole 6 can be adjusted with the adjusting screw 7, thereby adjusting the contact pressure of the damping ball 9 against the guide shaft 12 and controlling the reset speed of the protective panel 3.

[0028] It should be noted that this utility model is an engineering machinery instrument panel with an anti-accidental touch structure. During operation, the operator pulls the bottom operating handle 15 of the U-shaped side plate 4, causing the slider 5 to move vertically and radially along the guide shaft 12 within the slide groove 10. This opens the protective panel 3 upwards or downwards, and the slider 5 compresses the compression spring fitted on the outside of the guide shaft 12, thereby exposing the front operating area of ​​the control instrument 1. The limiting plug 13 at the top or bottom of the slider 5 then engages with the slot 11 at the top or bottom of the slide groove 10, temporarily limiting the protective panel 3 and facilitating operation. When the protective panel 3 is reset, the protective panel 3 can be slightly pushed up or down to disengage the limiting plug 13 that is inserted into the slot 11. At this time, the slider 5 can be pushed to slide in the slide groove 10 by the force of the compression spring on the outside of the guide shaft 12, thereby cooperating with the U-shaped side plate 4 to reset the protective panel 3. The base 8, which is subjected to the force of the compression spring in the countersunk hole 6, drives the damping ball 9 to abut against the outside of the guide shaft 12, thereby providing damping for the movement of the slider 5 and preventing the protective panel 3 and the slider 5 from rapidly impacting the control instrument 1.

[0029] When adjusting the opening direction of the protective panel 3, the guide shaft 12 can be unscrewed from the slide groove 10 first. Then, the protective panel 3 can be manually pried off the front of the control instrument 1, so that the two sliders 5 can be disengaged from the corresponding slide groove 10 by means of the toughness of the U-shaped side plate 4 and the slope on one side. Then, the protective panel 3 can be flipped over and the sliders 5 can be reinstalled into the corresponding slide groove 10. The guide shaft 12 can be re-threaded into the slide groove 10.

[0030] When adjusting the reset speed of the protective panel 3, rotating the adjusting screw 7 can change the compression of the compression spring in the countersunk hole 6, thereby adjusting the contact pressure of the damping ball 9 against the guide shaft 12. This controls the reset speed of the protective panel 3, preventing damage to components from excessively fast reset, and allowing for flexible adjustment of damping according to actual needs. This ensures stable reset of the protective panel 3 under different operating conditions. At the same time, the protective panel 3 also protects the operating area of ​​the control instrument 1 from accidental touches.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
