Description

Shockproof support of projector

Technical Field

The utility model relates to an articles for daily use field especially relates to a projecting apparatus support that takes precautions against earthquakes.

Background

The projector is a precise electronic component, and under some special use environments, the vibration transmitted by the projector bracket can affect the working state of the projector, even the working life of the projector. For example, when a projector fixed on a cart is transferred, some vibration is inevitably generated during moving and using. As a highly sophisticated electronic product, portable office projectors are quite sensitive to shocks. If the portable office projector is improperly protected and the internal optical system devices (such as a liquid crystal panel) are shifted due to vibration, even if the color deviation is only 1mm, the color deviation can be displayed on the picture. The lens and the reflector in the optical system are also deformed or damaged due to vibration, which affects the image projection effect. The track of the zoom lens is damaged under impact, so that the lens is stuck and even the lens is broken and cannot be used.

Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.

Fig. 1 is a schematic view of the shockproof bracket structure of the projector according to the present invention. The shockproof support of projecting apparatus includes: the mounting structure comprises a first mounting frame 1, a second mounting frame 2, a damping part 3 and a bolt 4. The first mount 1 is flat. The first mounting frame 1 is made of engineering plastic with the thickness of 1-3 mm. For example, engineering plastics suitable as the first mount 1 may be ABS, PC, PMMA. Or selecting any one of suitable metal materials such as aluminum alloy, beryllium bronze, stainless steel and galvanized sheet. The first mount 1 is fixed to the mount by bolts 4. The number of the bolts 4 is at least two, and the first mounting frame 1 is provided with through holes corresponding to the bolts 4.

The second mounting bracket 2 includes a first screw hole 21 and a second screw hole 22. The second mounting bracket 2 is connected with the projector through a first screw hole 21, and the second mounting bracket 2 is connected with the first mounting bracket 1 through a second screw hole 22. The first screw hole 21 and the second screw hole 22 are corresponding to screws (not shown). The first screw holes 21 are transversely provided with a plurality of first screw holes, and are suitable for projectors of different models by arranging redundant screw holes.

The shock-absorbing part 3 includes a third screw hole 31. The damper 3 is provided between the second mount 2 and the projector. For reducing the frequency of vibrations transmitted into the projector core. The cushioning portion 3 is a pad made of a cushioning material. The shock absorbing material may be a foam material or a silicone material. The pad may be designed as a foam pad with 3M double-sided tape attached to one side, and the foam pad is directly attached to the bottom of the second mounting bracket 2 at a position such that the third screw holes 31 correspond to the first screw holes 21. The pad of the cushioning portion 3 may be arranged in plural, for example, two, three, four in the lateral direction. The pad is preferably generally rectangular in shape and preferably about 1-5mm thick. The third screw hole 31 is designed to include at least one step, which can be used to adjust the fastening degree. The foam pad having a certain thickness can provide a shock absorbing performance while making the installation more secure because it has a certain resilience. In the installation the utility model discloses a shockproof support in-process of projecting apparatus, the decrement of buffer portion 3 is 1/3 ~ 1/2 of thickness.
