Abstract
The utility model provides a projecting apparatus increases steady device is provided with fixed station and a plurality of big spring on the platen, is provided with elastic block and a plurality of little spring on the fixed station, and the mounting panel of projecting apparatus is installed on the elastic block, and the mounting panel also with big spring and little spring coupling, the elastic block has elasticity. The beneficial effects are that: the large spring and the small spring respectively buffer the energy of vibration, and because the characteristics of the springs still transmit part of vibration to the mounting plate, the springs with different forms and different stiffness coefficients are adopted for energy hedging so as to achieve the purpose of reducing vibration; the mounting plate is mounted on a structure with elasticity, and the vibration transmission can be reduced by the mounting plate itself or a matched spring of the mounting plate.
Description
Technical Field
The utility model relates to a stabilising arrangement of projecting apparatus especially indicates a projecting apparatus increases steady device.
Background
A projector, also called a projector, is a device that can project images or videos onto a curtain, and can be connected with a computer, a VCD, a DVD, a BD, a game machine, a DV, etc. through different interfaces to play corresponding video signals.
Projectors are widely used in homes, offices, schools and entertainment places at present, and have different types such as CRT, LCD and DLP according to different working modes.
The projector can shake due to external interference, so that a projection picture shakes, a user cannot watch a stable projection picture easily, and normal use of the user is affected.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that exists among the prior art, provide a projecting apparatus and increase steady device.
The technical scheme of the utility model is realized like this: a projector stabilization device, comprising: the projector comprises a table plate and supporting legs arranged on the table plate, wherein a fixed table and a plurality of large springs are arranged on the table plate, an elastic block and a plurality of small springs are arranged on the fixed table, a mounting plate of the projector is arranged on the elastic block, the mounting plate is also connected with the large springs and the small springs, and the elastic block has elasticity.
Further, the large spring is a fixed extension spring, and the small spring is a fixed compression spring.
Further, the stiffness coefficient ratio of the big spring to the small spring is 1.5-1.8.
Further, the ratio of the stiffness coefficient of the elastic block to the stiffness coefficient of the small spring is 0.1.
The utility model has the advantages that: the large spring and the small spring respectively buffer the energy of vibration, and because the characteristics of the springs still transmit part of vibration to the mounting plate, the springs with different forms and different stiffness coefficients are adopted for energy hedging so as to achieve the purpose of reducing vibration; the stiffness coefficient of the elastic block is one fifth of that of the small spring, the mounting plate is mounted on the structure with elasticity, and the vibration transmission can be reduced by the mounting plate or the spring matched with the mounting plate.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, a projector stabilization device includes: platen 2 and the supporting leg 1 of installing on platen 2 are provided with fixed station 5 and a plurality of big spring 3 on platen 2, are provided with elastic block 7 and a plurality of little spring 6 on fixed station 5, and the mounting panel 4 of projecting apparatus is installed on elastic block 7, and mounting panel 4 also is connected with big spring 3 and little spring 6, and elastic block 7 has elasticity.
The large springs 3 and the small springs 6 are equal in number and are evenly arranged around the elastic block 7.
The large spring 3 is a fixed extension spring, the small spring 6 is a fixed compression spring, the large spring 3 is positioned at the periphery of the fixed table 5, the small spring 6 is a compression spring, the stiffness coefficient ratio of the large spring 3 to the small spring 6 is 1.5-1.8, when the vibration of the supporting leg 1 is transmitted to the bedplate 2, the large spring 3 and the small spring 6 respectively buffer the vibration energy, and because the characteristics of the springs still transmit a part of the vibration to the mounting plate 4, the springs with different forms and different stiffness coefficients are adopted for energy hedging so as to achieve the purpose of reducing the vibration; the ratio of the stiffness coefficient of the elastic block 7 to the stiffness coefficient of the small spring 6 is 0.1, the mounting plate 4 is mounted on a structure with elasticity, and the vibration transmission can be reduced by the elastic block or the spring matched with the elastic block.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
