Abstract
The utility model discloses a fan mounting structure of a front projection camera, which can absorb vibration. The fan mounting structure comprises a fan which is arranged inside a bottom plate fan insertion slot and then fixed on a bottom plate through a press plate. A first vibration-absorbing layer and a second vibration-absorbing layer are arranged between the fan and the fan insertion slot and between the fan and the press plate respectively. The fan mounting structure effectively reduces the vibration of the complete machine and noise arising from the running of the fan, ensures normal operation of the complete machine, and prolongs the service life of the internal components of the machine. The fan mounting structure has more convenient assembly, and is mainly used in the front projection camera.
Description
Technical field
The utility model relates to a kind of front projection machine, especially a kind of front projection machine fan mounting structure.
Background technology
Front projection machine owing to have can go out at less space inner projection bigger picture, volume little, be convenient to move and advantages such as placement, in daily study of today, work and life, use more and more widely.As if the confidential fan of using of front projection dispels the heat to complete machine, and an outstanding cooling system is to the life-span of complete machine and the low noise effect of having greatly improved of complete machine, but existing front projection machine fan mounting structure has been ignored this point.Existing front projection machine fan generally has two, be to be assembled to like this in the casing: directly utilize four screws of four jiaos in fan that fan is fixed on the chassis sidewall, perhaps, fan is fixed on the L shaped sheet metal component, again this sheet metal component is fixed on the base plate of casing.The casing complete machine oscillation that the fan operation causes under this dual mode is bigger, and noise is bigger.
The utility model content
In order to overcome the bigger deficiency of vibration that existing front projection machine fan mounting structure causes, technical problem to be solved in the utility model provides a kind of front projection machine fan mounting structure that can vibration damping.
The technical scheme that its technical matters that solves the utility model adopts is: the front projection machine fan mounting structure, comprise the fan that is installed on the casing, and be provided with the vibration damping layer between described casing and the fan.
Described fan is fixed on the base plate of casing, and base plate is provided with and the suitable fan-slot of fan profile, is provided with the first vibration damping layer as the vibration damping layer between fan and fan-slot.
Described fan is fixed on the described base plate by pressing plate, and screw is connected between pressing plate and the base plate.
Corresponding to the position of fan power supply line wired hole is set at described pressing plate.
Be provided with the second vibration damping layer between described fan and the pressing plate as the vibration damping layer.
Position corresponding to the fan power supply line on the described second vibration damping layer is provided with breach.
The beneficial effects of the utility model are: weakened complete machine oscillation and noise that the fan operation causes effectively, ensured that the complete machine operate as normal prolongs the internal body spare life-span simultaneously, and assemble more convenient.
Description of drawings
Fig. 1 is a synoptic diagram of the present utility model.
Be labeled as base plate 1, fan-slot 2, the first vibration damping layer 3, fan 4, pressing plate 5, screw 6, via hole 7, line hole 8, breach 9, screw post 10, the second vibration damping layer 11 among the figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, front projection machine fan mounting structure of the present utility model comprises the fan 4 that is installed on the casing, is provided with the vibration damping layer between described casing and the fan 4.By being set, the vibration damping layer weakens complete machine oscillation and the noise that the fan operation causes effectively between casing and fan 4.
For convenient for assembly, described fan 4 preferably is fixed on the base plate 1 of casing, and base plate 1 is provided with and the suitable fan-slot 2 of fan 4 profiles, is provided with the first vibration damping layer 3 between fan 4 and fan-slot 2.
For convenient for assembly and further fan is fixed, reduce vibration, described fan 4 preferably is fixed on the described base plate 1 by pressing plate 5, and screw is connected between pressing plate 5 and the base plate 1, described pressing plate 5 can adopt sheet metal component, and can simultaneously two desk fans 4 all be fixed on the base plate 1.
Be connected for making things convenient between fan power supply line and the circuit board, described pressing plate 5 is provided with the line hole 8 that the power supply source line passes through corresponding to the position of fan power supply line.
For further reducing vibration, be provided with the second vibration damping layer 11 between described fan 4 and the pressing plate 5.
Be connected for making things convenient between fan power supply line and the circuit board, the position corresponding to the fan power supply line on the described second vibration damping layer 11 is provided with breach 9.
