AI Technical Summary
The right-side window of the electric loader cab lacks an effective limiting device during operation, which may cause the window to open excessively, posing a safety hazard. In dusty or rainy weather, it needs to be adjusted frequently, affecting the driver's safety and comfort.
A limiting device is designed, comprising a frame, a right-side window, a limiting bracket, and a limiting part. The limiting part abuts against the frame to limit the opening angle of the window and prevent excessive rotation. Combined with hinges and bolts, it enables quick adjustment and prevents impact damage.
It improves the convenience and safety of window operation, prevents excessive opening and closing of windows, reduces the failure rate, and enhances overall safety and comfort. At the same time, it has a simple structure, is easy to install, and is low in cost.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cab accessories for construction machinery, and in particular to a right window limiting device for an electric loader cab. Background Technology
[0002] Loaders are construction equipment used in basic engineering projects, commonly used in highways, buildings, ports, mines, and other construction projects. They are widely used for the transfer and stockpiling of granular materials such as sand, gravel, and coal. The right-side window of the electric loader cab requires an appropriate limiting device during operation to ensure that the window remains within a predetermined angle range when opened, avoiding safety hazards caused by excessive opening and ensuring the safety and comfort of the driver. Furthermore, in stable working conditions such as high dust levels or rainy days, the driver may need to frequently adjust the window opening angle. Therefore, a limiting bracket that limits the opening angle but does not lock is particularly important. Utility Model Content
[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a right window limiting device for the cab of an electric loader.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A right window limiting device for the cab of an electric loader includes:
[0006] The frame installed on the driver's cab;
[0007] The right-side window is fixedly attached to the frame;
[0008] The limit bracket is fixedly connected to the cab;
[0009] The limiting part is threadedly connected to the limiting bracket;
[0010] When the frame and the right-side window are opened, the frame abuts against the limiting part.
[0011] Preferably, the limiting part is a shock-absorbing pad.
[0012] Furthermore, a hole seat is fixedly connected to the limiting bracket, and the limiting part is fixedly connected to the hole seat by bolts.
[0013] Furthermore, the cab is connected to a hinge, which is fixedly connected to the frame.
[0014] Furthermore, the limiting bracket is provided with mounting holes that match the screws on the hinge.
[0015] Compared with the prior art, this utility model provides a right window limiting device for the cab of an electric loader, which has the following advantages:
[0016] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model, through the limiting device set in the device, is easy to operate, and the staff can quickly adjust the opening and closing angle of the right window, and prevent the window from opening and closing too much, thus improving the convenience and safety of operation. At the same time, through the limiting part set on the limiting bracket, it can effectively prevent the frame from rotating too fast and being damaged by impact, further improving the safety of use. Attached Figure Description
[0017] Figure 1 This is a schematic diagram of the structure of a right window limiting device for the cab of an electric loader proposed in this utility model;
[0018] Figure 2 This is a schematic diagram of the limiting bracket in the right window limiting device of the electric loader cab proposed in this utility model.
[0019] In the diagram: 1. Cab; 2. Limiting part; 3. Limiting bracket; 4. Hinge; 5. Right side window; 6. Frame; 7. Mounting hole; 8. Hole seat. Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example:
[0022] Reference Figures 1-2 A right window limiting device for the cab of an electric loader, comprising:
[0023] Frame 6 installed on cab 1;
[0024] Right-side window 5 is fixedly connected to frame 6;
[0025] The limiting bracket 3 is fixedly connected to the cab 1;
[0026] The limiting part 2 is threadedly connected to the limiting bracket 3;
[0027] When frame 6 and right-side window 5 are opened, frame 6 abuts against limit part 2.
[0028] Limiting part 2 is a shock-absorbing pad.
[0029] A hole seat 8 is fixedly connected to the limiting bracket 3, and the limiting part 2 is fixedly connected to the hole seat 8 by bolts.
[0030] The cab 1 is connected to a hinge 4, which is fixedly connected to the frame 6.
[0031] The limiting bracket 3 has a mounting hole 7, which matches the screw on the hinge 4.
[0032] It should be noted that in actual use, the limit bracket 3 and hinge 4 can be installed and fixed on the cab 1 by passing screws through the mounting hole 7 and hinge 4.
[0033] Reference Figures 1-2 During the use of the window, the staff pushes the frame 6 to rotate, which will drive the right window 5 to rotate, and then the right window 5 can be opened;
[0034] During the opening of the right window 5, after the right window 5 rotates to a certain angle, the frame 6 will abut against the limiting part 2. At this time, the limiting part 2 on the limiting bracket 3 abuts against the frame 6, and the right window 5 will no longer be able to rotate.
[0035] It should be noted that, in the specific implementation process, the limit bracket 3 of different sizes can be replaced to set the maximum opening angle of the right side window 5, allowing it to be freely adjusted to different angles within the set angle.
[0036] The device is easy to operate, allowing staff to quickly adjust the opening angle of the right window and prevent excessive opening and closing of the window, thus improving operational convenience and safety. At the same time, the limiting part 2 on the limiting bracket 3 can effectively prevent the frame 6 from rotating too fast and being damaged by impact, further improving the safety of use.
[0037] It should also be noted that the absence of a locking device in this system reduces the failure rate of the right window lock in the cab 1, thus improving reliability. At the same time, the limiting device is easy to install, has a simple overall structure, does not take up space, does not require additional auxiliary fixing structures on the vehicle body, has lower initial design costs, and is more convenient for subsequent market parts maintenance. While ensuring the overall performance of the cab 1, it improves the usability and comfort of the right-side window.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
