Description

Technical Field

[0001] The utility model relates to the technical field of the cab body of construction machinery, in particular to a novel push-pull window that can be opened in the cab. Background Art

[0002] In the field of construction machinery, the design of the cab window is crucial for improving the working environment of the operator. However, there are many deficiencies in the existing technologies. Traditional windows often use adhesive sealing strips, and this sealing method is prone to falling off, affecting the sealing performance, resulting in the intrusion of dust, moisture and noise, and reducing the comfort. In addition, the window opening mechanisms of many old models are complex and inconvenient to operate, increasing the operation difficulty and the response time in case of emergency. At the same time, traditional push-pull windows often require a large space when opening, restricting the window size design and the overall layout of the cab. Fixed or small-area push-pull windows limit the air circulation and the field of vision, and are not conducive to comprehensively monitoring the surrounding environment. Most traditional cab windows do not have an adjustment function and cannot adjust the window opening size according to the external environment, reducing the driving convenience and safety. Therefore, it is particularly important to develop a novel cab push-pull window, which should have good sealing performance, a simple operation method, and the characteristics of being freely adjustable, etc., to comprehensively improve the use experience and working efficiency of the construction machinery cab.

[0026] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manners, structures, features, and effects of the present utility model as follows.

[0027] As Figures 1-5The shown new type of push-pull window with an openable cab includes a window frame sheet metal 1, a rubber strip 3, an operating mechanism 4, a switching mechanism 5, a linkage mechanism 6, and a glass 2. The strip-type triangular sealing rubber strip 3 is fixed on the window sheet metal 1 and is closely connected to the glass 2, ensuring a good sealing effect. Compared with the traditional adhesive sealing strip, it has the characteristics of firm and tight installation, while the previous adhesive type was prone to falling off. The sealing contact surface is triangular. Compared with the traditional circular sealing bubble, after being pressed, the contact surface is larger and the sealing surface is double-layered, which can more effectively prevent noise, water, dust, and pollutants from entering the interior of the cab, improve the sound transmission loss of the cab, ensure the sound quality of closing the window, and avoid abnormal noises.

[0028] The operating mechanism 4 includes an operating handle 41, a limit rod 42, a fixed seat 43, and a push-pull armrest 44. The limit rod 42 is fixedly connected to a first fixing frame 46 through a connecting rod 45. The first fixing frame 46 is fixed on the window frame sheet metal 1. The limit rod 42 is movably connected to the operating handle 41. One end of the operating handle 41 is fixed on the side wall of the fixed seat 43 and is movably connected to the fixed seat 43. The cross-section of the fixed seat 43 is U-shaped. The fixed seat 43 and a clamping plate 47 are located on both sides of the glass 2, and the three are fixed through bolts to achieve the fastening of the fixed seat 43, the glass 2, and the clamping plate 47. The side wall of the fixed seat 43 is fixedly connected to one end of the push-pull armrest 44, and the other end of the push-pull armrest 44 is fixedly connected to a fixing plate 48. The fixing plate 48 is fixedly connected to the linkage mechanism 6.

[0029] The operating handle 41 includes a connection hole 411, a hand-held part 412, and a slideway 413. Shaft rods are fixed on the side walls at both ends of the fixed seat. The shaft rods pass through the sleeves 4111 in the connection hole 411 to enable the operating handle to rotate around the shaft rods. A downward groove is provided inside the connection hole 411, and a spring 4112 is placed in the groove. The connection hole 411 is located on the upper left side of the operating handle 41, the hand-held part 412 is located on the lower right side of the operating handle 41, and the slideway 413 extends from the upper right side to the lower left side of the operating handle 41. The slideway 413 is generally L-shaped. The limit rod 42 can slide along the slideway 413 to solve the problem that the window cannot be opened to too large an angle under space constraints and can well serve the purpose of ventilation. If space conditions permit, the limit rod 42 can be removed from the slideway 413, and the switching mechanism 5 is used to control the large-angle opening.

[0030] The upper end of the switching mechanism 5 is fixedly connected to a second fixing frame 51. The second fixing frame 51 is fixed on the window frame sheet metal 1. The lower end of the switching mechanism is fixedly connected to an L-shaped plate 52. The L-shaped plate 52 is fixedly connected to the linkage mechanism 6. The switching mechanism 5 is a gas spring, mainly solving the problems of large-angle opening and closing of the window.

[0031] The number of the linkage mechanisms 6 is two, which are arranged vertically. The L-shaped plate 52 is fixed to the side plate of the upper linkage mechanism 6 by bolts. They are respectively located on both sides of the glass 2. The L-shaped plate 52, the glass 2 and the side plate of the linkage mechanism 6 are fastened together by bolts. The fixing plate 48 is fixed to the side plate of the lower linkage mechanism 6 by bolts. They are respectively located on both sides of the glass 2. The fixing plate 48, the glass 2 and the side plate of the linkage mechanism 6 are fastened together by bolts. The other end side plates of the two linkage mechanisms 6 are respectively fixedly connected to the window frame sheet metal 1. The linkage mechanism 6 is a hinge.

[0032] Principle of use:

[0033] First, the operating handle is opened to put the sliding window into the unlocked state. Then, the window is opened by pushing the handrail. The switching mechanism controls the large-angle opening and closing of the window. The installation of the hinge structure enables the window to have a larger opening space and more flexible operation. However, when the opening space of the window is limited, the sliding of the limiting rod on the slideway will limit the opening angle of the window and can also achieve the effect of ventilation.

[0034] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
