Abstract
The utility model discloses a rain-proof structure in driver's cabin top, the holistic height that highly is higher than the driver's cabin frame in skylight, skylight window edge forms ascending cavity joint strip assembly hem, and cavity joint strip assembly hem department is provided with round cavity joint strip, and the driver's cabin skylight is whole to be higher than the driver's cabin frame, and the rainwater is outwards flowed all around from the skylight naturally, can't form ponding around the skylight, guarantees that the driver's cabin does not have the infiltration. When the skylight is closed, the hollow sealing rubber strip is elastically deformed after being extruded, a wider sealing contact surface can be realized by matching with a sealing rubber sheet of the skylight, the sealing performance of the skylight in the closed state is effectively improved, and when the skylight is opened, the hollow sealing rubber strip rebounds to be in a natural state; the height of the rubber strip is far higher than that of the cab frame, so that the rainproof effect of the cab is optimized.
Description
Technical Field
The utility model relates to a technical field of the sealed scheme in excavator driver's cabin skylight, specific rain-proof structure in driver's cabin top that says so. And more particularly to a mechanical coupling structure thereof.
Background
The working environment of the excavator is generally poor, the working condition is complex, the pollution of sand, stone, dust and the like is large, and the working position is in a half-slope inclined state; plus heavy rain weather. The ability of preventing rainwater infiltration of excavator driver's cabin top will reduce, and the infiltration may appear in driver's cabin top skylight periphery, leads to the interior rainwater drippage of driver's cabin.
Disclosure of Invention
An object of the utility model is to provide a driver's cabin top rainproof structure adopts open skylight, and skylight department has set up the joint strip of cavity formula, improves driver's cabin top prevention of seepage water ability, promotes the travelling comfort of driver's cabin. Overcomes the defects in the prior art.
In order to realize the purpose, the technical scheme of the utility model is that: a driving cab top rainproof structure comprises a skylight opening, wherein a skylight is arranged at the skylight opening, the rear side of the skylight is hinged to a driving cab frame at the rear side of the skylight opening, the whole height of the skylight is higher than that of the driving cab frame, an upward hollow sealing rubber strip assembling folded edge is formed at the edge of the skylight opening, the hollow sealing rubber strip assembling folded edge is distributed at the edge of the skylight opening in a surrounding mode, a circle of hollow sealing rubber strip is arranged at the edge of the hollow sealing rubber strip assembling folded edge, the hollow sealing rubber strip is composed of a deformation part at the upper part and an assembling part at the lower part, an extension part is formed at the lower edge of the inner side of the assembling part in an inward and downward inclined mode, the deformation part is of a pipe body structure with a circular cross section, a sealing flange is formed in the inward and upward inclined mode in the deformation part, a concave part is formed in the inner wall and the outer wall of the joint of the deformation part and the assembling part, the horizontal plane at the lowest point of the extension part is lower than the horizontal plane of the bottom of the assembling part, and a sealing rubber sheet matched with the hollow sealing rubber strip is formed at the lower edge of the skylight opening.
The utility model discloses a rain-proof structure in driver's cabin top, driver's cabin skylight whole are higher than the driver's cabin frame, and the rainwater is outside outflow all around from the skylight naturally, can't form ponding around the skylight, guarantees that the driver's cabin does not have the infiltration. When the skylight is closed, the hollow sealing rubber strip is elastically deformed after being extruded, a wider sealing contact surface can be realized by matching with a sealing rubber sheet of the skylight, the sealing performance of the skylight in the closed state is effectively improved, and when the skylight is opened, the hollow sealing rubber strip rebounds to be in a natural state; the height of the rubber strip is far higher than that of the cab frame, so that the rainproof effect of the cab is optimized.
Drawings
Fig. 1 is the structural schematic diagram of the skylight opening state of the present invention.
Fig. 2 is the structural schematic diagram of the closed state of the skylight of the present invention.
Fig. 3 is a perspective view of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings.
The utility model discloses a rain-proof structure in driver's cabin top, it is different from prior art and lies in: the assembly device comprises a cab frame 10, wherein a skylight 1 is arranged at the cab frame, a skylight 2 is arranged at the skylight 1, the rear side of the skylight 2 is hinged with the cab frame at the rear side of the skylight 1, the overall height of the skylight 2 is higher than that of the cab frame, an upward hollow sealing rubber strip assembly folding edge 3 is formed at the edge of the skylight, the hollow sealing rubber strip assembly folding edges 3 are distributed at the edge of the skylight in a surrounding manner, a circle of hollow sealing rubber strip 4 is arranged at the hollow sealing rubber strip assembly folding edge 3, the hollow sealing rubber strip 4 consists of an upper deformation part 5 and a lower assembly part 6, an extension part 11 is formed by inwards and obliquely downwards the lower edge of the inner side of the assembly part 6, and when the hollow sealing rubber strip is in a pressed and deformed state, extension portion 11 that the cyclic annular distributes can increase the ductility at cavity joint strip edge, promotes sealing performance, and deformation portion 5 is circular shape tubular structure for the cross-section, and its inner chamber is the cavity form, and 5 inside slopes of deformation portion upwards form sealing flange 7, and when cavity joint strip receives the pressure deformation state, sealing flange 7 can cooperate joint strip 9 to promote the leakproofness at cavity joint strip edge, the inner wall and the outer wall department of the junction of deformation portion 5 and assembly portion 6 all form depressed part 8, and the horizontal plane of 11 nadirs in extension portion is less than the horizontal plane of 6 bottoms in assembly portion, 2 lower limb in skylight form with above-mentioned cavity joint strip 4 complex joint strip 9.
The design of the skylight of the cab is higher than that of the cab body, and the height of the water storage area formed at the top of the cab is lower than that of the skylight at the top under the condition of heavy rain or heavy rain. Guarantee inside the unable infiltration driver's cabin of rainwater, solved present driver's cabin top infiltration problem.
The foregoing is a more detailed description of the invention, taken in conjunction with the accompanying preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described above. For those skilled in the art of the present invention, for example, the object to be fixed is a circular object that is not an energy accumulator, or the structures of the lower support and the upper support of the energy accumulator are different, but the mounting and fixing mechanisms are the same. Without departing from the concept of the present invention, a plurality of simple deductions or replacements can be made, all of which should be considered as belonging to the protection scope of the present invention.
