Description

Side window mechanism of cab

Technical Field

The utility model belongs to the engineering machine tool field, specifically speaking especially relates to a driver's cabin side window mechanism.

Background

Currently, in the field of construction machinery, in order to ensure the visual field and the ventilation requirement, a cab is provided with a side window. The existing cab side window is generally opened in a plane type sliding window, a front push opening type and a back push opening type. These three opening side windows have the following disadvantages: 1. the sliding window is high in manufacturing cost and inconvenient to popularize; 2. the front-push opening type and rear-push opening type side windows need larger opening space, and the convenience of an operator for closing the windows in a cab is poor; 3. the existing side window structure can not be used for window opening and ventilation in rainy days. At present, a cab side window mechanism which is convenient to open and close, good in adaptability, good in ventilation and low in cost does not exist.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the side window mechanism of the cab overcomes the defects of the prior art, has low production cost and good ventilation effect, realizes the upward-lifting type opening, saves the space and improves the opening and closing convenience of the window.

The cab side window mechanism comprises a window frame, glass is installed in the window frame, sealing rubber strips are arranged on the periphery of the window frame, two sides of the top of the window frame are respectively provided with a fixed hinge, the bottom of the window frame is provided with a locking mechanism, one side or two sides of the window frame are provided with a hinged seat fixedly connected, and the hinged seat is hinged to one end of a supporting mechanism through a joint bearing.

Preferably, the cab is further included, the top of the window frame is fixedly connected with the cab through a fixed hinge, and the other end of the supporting mechanism is hinged with the cab through a joint bearing.

Preferably, the supporting mechanism adopts a gas spring or a limit wind brace.

Preferably, the locking mechanism is a latch or a catch with a rotating handle.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model has low cost and good applicability, and can realize the opening of the side window in rainy weather by the lifting-up opening mode, avoid rainwater from entering the cab, realize better ventilation, provide better driving environment for the driver and facilitate the communication between the driver and the personnel outside the cab;

2. the supporting mechanism adopts the air spring to support the side window, so that the window can be opened and closed stably, and in addition, the joint bearings are used at the two ends of the air spring, so that the vibration generated when the whole machine works can be effectively reduced, the noise is reduced, and the comfort is improved;

3. the utility model can realize the single hand opening and closing of the side window, and the convenience of opening and closing the window is improved; the locking mechanism is simple in structure, and the side window can be locked by rotating a handle of the locking mechanism; the sealing rubber strips on the periphery of the window frame improve the sealing performance of the window.

In the drawings, 1, a hinge is fixed; 2. sealing rubber strips; 3. a window frame; 4. glass; 5. a support mechanism; 6. a locking mechanism; 7. a hinged seat; 8. a knuckle bearing; 9. a cab; 10. a card holder; 11. hooking feet; 12. and (4) anti-skid bulges.

Detailed Description

The invention will be further described with reference to the following examples:

the first embodiment is as follows: as shown in fig. 1, driver's cabin side window mechanism, including window frame 3, install glass 4 in the window frame 3, window frame 3 is provided with joint strip 2 all around, 3 top both sides of window frame are fixed with fixed hinge 1 respectively, fixed hinge 1 and driver's cabin 9 fixed connection are passed through at 3 tops of window frame, and 3 bottoms of window frame are equipped with locking mechanism 6, and fixed connection's articulated seat 7 is installed to one side of window frame 3, and articulated seat 7 is articulated with 5 one end of supporting mechanism through joint bearing 8, and the 5 other ends of supporting mechanism pass through joint bearing 8 and are articulated with driver's cabin 9.

Example two: the two sides of the window frame 3 are respectively provided with a fixedly connected hinge seat 7, and the two hinge seats 7 are respectively hinged with a support mechanism 5, and the rest is the same as the first embodiment.

When the utility model is manufactured, the supporting mechanism 5 adopts an air spring or a limit air support, preferably the air spring, the locking mechanism 6 adopts a lock catch or a buckle with a rotating handle, and the cab 9 is provided with a clamping seat 10 matched with the locking mechanism 6; sealing rubber strip 2 can select for use conventional structure, also can select for use the structure that the area colluded foot 11, as shown in fig. 4 and fig. 5, has on sealing rubber strip 2 and colludes foot 11 and non-slip raised 12, and sealing rubber strip 2 installs in the recess of window frame 3 through colluding foot 11, and non-slip raised 12 and 3 internal surface contact of window frame avoid sealing rubber strip 2 to shift.

When the utility model is used, as shown in fig. 2, the handle of the locking mechanism 6 is rotated to separate the limiting block on the handle from the clamping seat 10, so as to remove the locking state of the side window, and the side window is opened in an upward lifting manner under the action of the air spring force; when the side window is opened, a rain shielding mechanism can be formed, rainwater is prevented from entering the cab, and window opening and ventilation in rainy days are realized. As shown in FIG. 3, when the side window is closed, the handle of the rotary locking mechanism 6 is used, so that the handle limiting block is clamped inside the clamping seat 10, the window is locked, and the sealing rubber strip 2 mounted around the window frame 3 can achieve a better sealing effect when the window is closed.

This driver's cabin side window mechanism realizes the steady switch window of singlehanded, has promoted the convenience of opening and shutting the window, and simultaneously, the air spring both ends and joint bearing cooperation can effectively alleviate the vibrations that the complete machine during operation produced, and the noise reduction has promoted the travelling comfort.
