Abstract
The utility model discloses an optical modulex height -adjustable's fixing device, its characterized in that: including being used for the support the base of each component of fixing device, be fixed in fixed column on the base, this fixed column has the blind hole that the inner wall set up the screw thread, the cover is located elastic element on the fixed column installs blooming group on this elastic element, and with blind hole screw -thread fit's adjusting screw. The utility model discloses simple structure, reasonable in design, it adjusts optical modulex's height through the spring to the elasticity of the blooming group of installing treating on it and adjusting and with fixed column screw -thread fit's adjusting screw's rotary motion, has effectively solved the machining tolerance of present structure to the influence of module height, has strengthened the display effect of projection picture.
Description
Technical field
This utility model relates to projection display apparatus, particularly relates to a kind of adjustable for height fixing device of optics module.
Background technology
The application of projector equipment is more and more general in the market, because its optics module is stricter to the requirement for height of fixed position, manufacturing technology is had higher requirement by it, the commonly used machine finishing of prior art ensures the height dimension of optics module mounting bracket, substantially can be controlled in ± 0.05mm within the scope of, but Projection Display effect also can be produced impact by the deviation of this scope, it is impossible to meet client's strict demand to image sharpness.
Summary of the invention
In view of the defect that prior art exists, the purpose of this utility model is to provide for a kind of adjustable for height fixing device of optics module, module height is impacted because of machining tolerance solving existing structure, and then affects the defect of projected picture.
To achieve these goals, the technical solution of the utility model is:
The adjustable for height fixing device of optics module, it is characterised in that:
Including the base for supporting the described each element of fixing device；
Being fixed on the fixing post on described base, this fixing post has the blind hole that inwall is threaded；
It is sheathed on the flexible member on described fixing post, this flexible member is installed blooming group；
And with the described blind threaded set screw coordinated.
Further, along the radial direction of described blind hole, the inwall of described blind hole locks glue groove at least provided with two places.
Preferably, described locking glue groove is symmetricly set on the inwall of described blind hole or described locking glue groove is uniformly arranged on the inwall of described blind hole along the circumferencial direction of described blind hole between two.
Further, described flexible member adopts spring element.
Compared with prior art, the beneficial effects of the utility model:
This utility model simple in construction, reasonable in design；It regulates the height of optics module by the elastic force of the spring blooming group to be regulated to being mounted thereon and the rotary motion of set screw that coordinates with fixing male screw, efficiently solve the impact on module height of the machining tolerance of existing structure, enhance the display effect of projected picture.

In figure: 1, set screw, 2, flexible member, 3, base, 4, fixing post, 41, locking glue groove, 5, optics module.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, this utility model is further elaborated.
As Figure 1-Figure 2, this utility model provides a kind of optics module height adjustable fixing device, and it includes set screw 1, flexible member 2, base 3 and fixing post 4.
Described set screw 1 rotates, by cooperating with the screw thread in described blind hole, the height regulating optics module；
Described flexible member 2 is sheathed on described fixing post 4, installs blooming group 5 on flexible member 2 top, and needs to ensure that flexible member 2 is produced pre-pressing force by it when installing original state；Described flexible member 2 preferably employs spring.
Described base 3 is used for supporting the described each element of fixing device；
Described fixing post 4 is riveted to base 3, and arranges its inwall on this fixing post 4 and have the blind hole of helicitic texture；Set screw 1 is squeezed in blind hole, is regulated the height of optics module by the elastic force of the flexible member 2 blooming group to be regulated to being mounted thereon and the rotary motion of set screw 1 that coordinates with fixing male screw.
Simultaneously along the radial direction of described blind hole, the blind hole inwall at fixing post 4 processes at least two place's locking glue grooves 41, to realize the locking to altitude mixture control screw 1；Namely installing initially, it is applied in the blind hole of fixing post 4 by locking glue in right amount, after final set screw 1 has adjusted, locking glue can be spilled between the screw thread in the blind hole of fixing post 4 and the screw thread of set screw 1 automatically, and is spilled in the locking glue groove 41 of fixing post 4.
Preferably, such as Fig. 3-Fig. 4, described locking glue groove is symmetricly set on the inwall of described blind hole between two or described locking glue groove is along the circumferential direction uniformly arranged on the inwall of described blind hole.
The design of above-mentioned locking glue groove 41 had both added set screw 1 and fixing post) between locking glue contact area, thus improving coupling mechanism force, again effectively avoid locking glue be spilled over to outside structure.
It addition, arrange the design of blind hole on fixing post 4, also ensure that locking glue can not be spilled over to below base 3, it is to avoid the impact on other structures of device.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive according to the technical solution of the utility model and utility model thereof and be equal to replacement or change, all should be encompassed within protection domain of the present utility model.
