Detailed Description

The following description of the embodiments refers to the accompanying drawings.

As shown in fig. 1 and 2, a sliding window 101 in the present embodiment includes a window frame 10 and a sliding window glass. The bottom edge 00 of the window frame is provided with a sliding groove, the bottom edge of the sliding window glass is positioned in the sliding groove, the sliding window glass is provided with a push-pull handle 20, the inner side of the bottom edge 11 of the window frame is fixedly provided with a limiting strip 30, the limiting strip 30 is provided with a limiting groove 32 with an upward opening, the push-pull handle 20 is fixed at the position of the sliding window glass close to the bottom edge and positioned above the limiting strip 30, and the push-pull handle 20 is provided with a bayonet 23 which can stretch up and down and is matched with the limiting groove 32. In the present invention, the inner side is a side facing the inside of the cab.

The bottom edge 11 of the window frame is provided with two sliding grooves, namely an inner sliding groove and an outer sliding groove. The sliding window glass comprises inner glass 14 and outer glass 15, the bottom edges of the inner glass 14 and the outer glass 15 correspond to the inner sliding groove and the outer sliding groove, push-pull handles 20 are mounted on the inner glass 14 and the outer glass 15, and limiting strips 30 are arranged on the inner sides of the positions of the inner glass 14 and the outer glass 15 when the inner glass and the outer glass are closed.

As shown in fig. 1, when the sliding window glass is closed, the rear vertical edge of the inner glass 14 is engaged with the frame rear vertical edge 12, and the front vertical edge of the outer end glass 15 is engaged with the frame front vertical edge 13. The push-pull handle on the inner glass 14 is installed at the lower part of the rear vertical edge of the inner glass 14, namely, near the junction and the adjacent part of the bottom edge and the rear vertical edge of the inner glass. The push-pull handle on the outer glass 15 is installed at the lower part of the front vertical edge of the outer glass 15, namely, near the junction of the bottom edge of the outer glass and the front vertical edge. The push-pull handle is arranged at the corner part of the sliding window glass, so that the influence of the push-pull handle on the opening range of the sliding window glass is reduced to the minimum.

The position-limiting strip 30 is arranged in parallel with the sliding groove on the bottom edge 11 of the window frame, and a plurality of position-limiting grooves 32 are arranged at intervals along the length direction. The plurality of stopper grooves 32 are provided so that the sliding window glass has several opening and locking amplitudes, and the sliding window glass can be locked after being opened by a predetermined opening degree without changing the amplitude due to vibration or inertia.

As shown in fig. 3, the push-pull handle 20 includes a handle body 21 fixedly connected to the sliding window glass, a latch handle 22 rotatably mounted on the handle body 21 for pulling the latch 23 to move up and down, and a return spring 24 disposed between the latch 23 and the handle body 21 for providing a downward elastic force to the latch 23. The click pin 23 is provided in the handle body 21 so as to be movable up and down along the guide groove in the handle body 21, and the lower end of the click pin 23 is protruded downward. When the bayonet handle 22 is pulled, the bayonet handle 23 rotates relative to the handle body 21 and drives the bayonet 23 to move upwards against the elastic force of the return spring 24, so that the bayonet 23 is disengaged from the limiting groove 32 of the limiting strip 30. After releasing the click handle 23, the click 23 is moved downward by the resilient force of the return spring 24, and when the click 23 is aligned with the stopper groove 32 of the stopper 30, the click 23 is inserted into the stopper groove 32, thereby locking the sliding window glass.

As shown in fig. 4, the bottom edge 11 of the window frame is provided with a slot 16 with an upward opening at the inner side of the inner sliding groove, and the limiting strip 30 is provided with an embedded connecting part 33 which is embedded into the slot 16 and fixedly connected with the bottom edge 11 of the window frame. In a more preferred embodiment, the position-limiting strips 30 are composed of three short position-limiting strips 31 connected in sequence in the length direction, and the sum of the lengths of two adjacent short position-limiting strips 31 is larger than the widths of the inner glass 14 and the outer glass 15. When the sliding window glass is disassembled, the inner sliding window glass and the outer sliding window glass simultaneously slide to one end of the sliding groove, so that the short limiting strip 31 positioned at the other end can be conveniently taken out from the clamping groove 16 without being blocked by the push-pull handle 20, and the middle short limiting strip 31 can be taken out when the inner glass 14 and the outer glass 15 are both in a closed state. In some embodiments, the stop strip 30 may be an integral strip that is fixed to the short side 11 of the window frame by screws, and the stop strip is removed after the screws are removed when the sliding window pane is removed.

In the present embodiment, since the push-pull handle 20 is installed at the bottom of the sliding window glass, there is no protruding part in the open space when the sliding window glass is opened, and the person will not be scratched by the protruding part when the person extends or retracts his head. The sliding window glass also has a plurality of opening degrees, and the bayonet 23 on the push-pull handle at each opening degree is matched with the limiting groove 32 on the limiting strip 30 to lock the sliding window glass, so that the sliding window glass is prevented from moving to change the opening degree due to vibration or inertia.

In some embodiments, only one of the panes mounted in the window frame is a sliding pane that can be pushed open and pulled open, the other pane is a fixed pane that is fixedly mounted, and no push-pull handle is mounted on the fixed pane.

The invention also provides a cab of the engineering machinery, such as a cab of an excavator, which is provided with the sliding window as shown in figure 5.
