[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to a sliding window for the cab of engineering machinery. Background Technology
[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.
[0003] As an important type of engineering machinery, loaders are widely used in logistics, construction and mining. They are mainly used for shoveling and loading bulk materials such as soil, sand, gravel, lime and coal. They can also perform light shoveling and digging operations on ores and hard soil. With different auxiliary working devices, they can also perform bulldozing, lifting and loading and unloading operations of other materials such as timber.
[0004] When operators sit in a sealed cab for a long time to operate the machine, ventilation is necessary when needed. However, the existing cab sliding window installation structure is complex and has low reliability. After the sliding window is opened, it is difficult to maintain the opening degree. Often, due to bumps, the sliding window will close or the opening degree will be reduced, which will affect ventilation and thus affect the operator's operation. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a sliding window for the cab of engineering machinery, which ensures the reliability of the sliding window in both closed and open states, maintains the sliding window at the required opening degree for ventilation, and thus ensures the ventilation effect. The overall structure is simple.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A sliding window for a cab of engineering machinery includes a sliding window hinge, a sliding window frame, a limiting block, a fixed shaft, and a sliding window handle. One end of the sliding window hinge is connected to the sliding window frame. A fixed shaft is provided in the middle of the sliding window frame, and a sliding window handle is provided on the fixed shaft. A limiting block is provided at one end of the fixed shaft. The limiting block has a first slot and a second slot, which are connected. A first limiting plate is provided on the sliding window handle, and a second limiting plate is provided on the rear side of the first limiting plate.
[0008] Furthermore, the first slot is located on the side of the limiting block, and the first slot and the first limiting plate are engaged.
[0009] Furthermore, the second slot is located above the limiting block, and the second slot and the second limiting plate are engaged.
[0010] Furthermore, the limiting block is installed on the cab door, and the limiting block and the cab door are fixedly connected.
[0011] Furthermore, the other end of the cab door hinge is detachably connected to the cab door, and the sliding window hinge is coaxial with the cab door hinge.
[0012] Furthermore, the fixed shaft and the sliding window frame are fixedly connected, while the sliding window handle and the fixed shaft are movably connected.
[0013] Furthermore, the sliding window handle and the first limiting plate are fixedly connected, and the rotation of the sliding window handle drives the first limiting plate to rotate.
[0014] Furthermore, the sliding window handle and the second limiting plate are fixedly connected, and the rotation of the sliding window handle drives the second limiting plate to rotate.
[0015] Furthermore, the dimensions of the first limiting plate and the first card slot are matched.
[0016] Furthermore, the dimensions of the second limiting plate and the second card slot are matched.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are:
[0018] This utility model incorporates a limiting block with a first and second locking groove. It also includes a sliding window handle with a first and second limiting plate. When the sliding window is open, the first limiting plate engages with the first locking groove to limit the window's position. When the sliding window is closed, the second limiting plate engages with the second locking groove to limit the window's position. This effectively solves the ventilation problem in the operator's cab when operating the machine. When the sliding window is open for ventilation, the limiting plate on the handle effectively engages with the locking groove of the limiting block, preventing the window from shaking due to machine vibrations. This ensures the reliability of the sliding window in both open and closed states, maintaining the window at the required opening for ventilation, thus guaranteeing ventilation effectiveness and improving the reliability of the sliding window.
[0019] The sliding window hinge and the driver's cab door hinge of this utility model are coaxial, which can effectively simplify the installation structure of the sliding window, simplify the overall structure, improve reliability, and reduce production costs. Attached Figure Description

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0025] When operators sit in a sealed cab for a long time to operate the machine, ventilation is necessary when needed. However, the existing cab sliding window installation structure is complex and has low reliability. After the sliding window is opened, it is difficult to maintain the opening degree. Often, due to bumps, the sliding window will close or the opening degree will be reduced, which will affect ventilation and thus affect the operator's operation.
[0026] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a sliding window for a driver's cab of engineering machinery, such as... Figure 1 and Figure 2 As shown, the window includes a sliding window hinge 2, a sliding window frame 3, a limiting block 5, a fixing shaft 6, and a sliding window handle 7. One end of the sliding window hinge 2 is connected to the sliding window frame 3. The fixing shaft 6 is set in the middle of the sliding window frame 3, and the sliding window handle 7 is set on the fixing shaft 6. The limiting block 5 is set at one end of the fixing shaft 6. The limiting block 5 is set with a first slot 10 and a second slot 11. A reinforcing beam is set between the first slot 10 and the second slot 11. The sliding window handle 7 is set with a first limiting plate 8, and a second limiting plate 9 is set on the rear side of the first limiting plate 8.
[0027] The limiting block 5 is provided with a first slot 10 and a second slot 11. The present invention also includes a sliding window handle 7, on which a first limiting plate 8 and a second limiting plate 9 are provided. When the sliding window is open, the first limiting plate 8 and the first slot 10 engage to limit the opening of the sliding window; when the sliding window is closed, the second limiting plate 9 and the second slot 11 engage to limit the closing of the sliding window. This effectively solves the ventilation problem in the cab when the operator is working on the machine.
[0028] When the sliding window is opened for ventilation, the limiting plate on the sliding window handle 7 is effectively engaged in the slot of the limiting block 5, which avoids the sliding window shaking caused by machine operation vibration, ensures the reliability of the sliding window in both closed and open states, keeps the sliding window at the required opening for ventilation, and thus ensures the ventilation effect and improves the reliability of the sliding window.
[0029] The limiting block 5 is installed on the driver's cab door 4, and the limiting block 5 and the driver's cab door 4 are fixedly connected. The first slot 10 is located on the side of the limiting block 5, and the first slot 10 is engaged with the first limiting plate 8. The second slot 11 is located on the upper part of the limiting block 5, and the second slot 11 is engaged with the second limiting plate 9. The other end of the sliding window hinge 2 is detachably connected to one end of the driver's cab door hinge 1, and the other end of the driver's cab door hinge 1 is detachably connected to the driver's cab door 4. The sliding window hinge 2 and the driver's cab door hinge 1 are coaxial. The coaxiality of the sliding window hinge 2 and the driver's cab door hinge 1 can effectively simplify the installation structure of the sliding window, resulting in a simple overall structure, improved reliability, and reduced production costs.
[0030] The fixed shaft 6 and the sliding window frame 3 are fixedly connected, while the sliding window handle 7 and the fixed shaft 6 are movably connected. The sliding window handle 7 is installed inside the sliding window frame 3. The sliding window handle 7 rotates along the fixed shaft 6, thereby driving the first limiting plate 8 and the second limiting plate 9 to rotate, realizing the engagement of the first limiting plate 8 with the first slot 10 and the second limiting plate 9 with the second slot 11. The sliding window can rotate together with the driver's cab door 4, or it can rotate independently to open and close.
[0031] The sliding window handle 7 is fixedly connected to the first limiting plate 8. Rotating the sliding window handle 7 causes the first limiting plate 8 to rotate. The sliding window handle 7 is also fixedly connected to the second limiting plate 9. Rotating the sliding window handle 7 causes the second limiting plate 9 to rotate. The dimensions of the first limiting plate 8 match the dimensions of the first slot 10. The dimensions of the second limiting plate 9 match the dimensions of the second slot 11. The dimensions of the first limiting plate 8, the second limiting plate 9, the first slot 10, and the second slot 11 can be set according to actual needs, ensuring that the dimensions of the limiting plates and slots match to guarantee stability after engagement and prevent loosening. Furthermore, multiple limiting plates and slots can be provided, allowing adjustment of the sliding window's opening degree to meet different needs.
[0032] Instructions for using the sliding window in the cab of construction machinery: To open the sliding window, rotate the sliding window handle 7, engaging the first limiting plate 8 on the handle 7 into the first slot 10 of the limiting block 5, thus placing the sliding window in the open limiting state. To close the sliding window, rotate the sliding window handle 7, engaging the second limiting plate 9 on the handle 7 into the second slot 11 of the limiting block 5, thus placing the sliding window in the closed state. This ensures the reliability of the sliding window in both open and closed states, preventing it from shaking due to bumps and maintaining the required opening degree for ventilation. This effectively simplifies the installation structure of the sliding window, improves reliability, and reduces production costs.
[0033] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
