Abstract
The utility model is related to projection display technique field, more particularly to a kind of TIR prism fixing device.The utility model provides a kind of TIR prism fixing device, including fixed pedestal, TIR prism, limit hook and limited screw, and fixed pedestal is provided with fixed pedestal guide rail bar, and limit hook is located in fixed pedestal guide rail bar, and limited screw is on limit hook.The TIR prism fixing device can effectively avoid TIR prism from continuing stress, reduce TIR prism and separated and cracking risk in bonding place.
Description
Technical field
The utility model is related to projection display technique field, more particularly to a kind of TIR prism fixing device.
Background technology
In the structured design process of projecting light path, TIR prism is that two pieces of Tp gluings are integrated, such as Fig. 5 institutes
Show, traditional TIR prism fixed form is the ray machine carrier as traditional TIR prism 12 with traditional fixed pedestal 11, it is provided
The anchor point coordinated with traditional TIR prism 12, the tradition pressure between traditional fixed strip 16 and traditional TIR prism 12 pays a sponge 13
For eliminating gap therebetween, the free degree of restricted T IR prism Y-directions.As shown in fig. 6, fixation spring tab 15 and traditional TIR prism
12 by certain amount of interference, the free degree of the X-direction of restricted T IR prisms, fastening screw 14 be used for by traditional fixed strip 16 with
Traditional fixed pedestal 11 links together.If applying positioning and the fixed form of sustained stress using traditional shell fragment, having can
TIR prism can be caused to be separated in bonding place, and because fixation spring tab is to the long-term force of TIR prism, TIR prism has cracking wind
Danger.
Therefore being badly in need of one kind can avoid TIR prism from continuing stress, reduce TIR prism and separated in bonding place and cracking risk
TIR prism fixing device.
Utility model content
In view of problem above, the utility model, which provides one kind, can avoid TIR prism from continuing stress, reduce TIR prism and exist
Bonding place separates the TIR prism fixing device with cracking risk.
In order to realize above-mentioned utility model purpose, the utility model provides a kind of TIR prism fixing device, and its feature exists
In, including fixed pedestal, TIR prism, limit hook and limited screw, the fixed pedestal are provided with fixed pedestal guide rail bar,
The limit hook is fixed in fixed pedestal guide rail bar, and the limited screw is on limit hook.Limited screw is used to limit
The free degree of TIR prism X-direction processed.
The limit hook is screwed in fixed pedestal guide rail bar, free for restricted T IR prisms Y direction
Degree.
The limit hook is provided with screw, and the screw is provided with screw thread, for making limited screw be fixed on limiting card
On hook and fixed pedestal guide rail bar.
Fixed strip is provided with the outside of the fixed pedestal.The fixed strip is screwed on fixed pedestal.
Sponge is paid provided with pressure on the inside of the fixed pedestal, for eliminating the gap between fixed strip and TIR prism.
Advantage and beneficial effect of the present utility model are there is provided one kind TIR prism can be avoided to continue stress, reduction TIR
Prism separates the TIR prism fixing device with cracking risk in bonding place.TIR prism fixing device in this programme is used can line
Property slide position limiting structure part fix TIR prism, pass through the slip of locating part, the processing of compatible TIR prism and pedestal mating surface
Error and rigging error, reach that just accessible mode carrys out the free degree of restricted T IR prisms with TIR prism, so as to avoid TIR ribs
Mirror continues stress.

Reference
1. the pressure of fixed pedestal 2.TIR prisms 3. is paid the limited screw 7. of 4. fixed strip of sponge, 5. limit hook 6. and fixed
It is tight that the traditional tradition of TIR prism 13. pressure of the traditional fixed pedestal 12. of 8. screw of base rail bar, 9. screw 11. pays sponge 14.
Gu the traditional fixed strip of 15. fixation spring tab of screw 16.
Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and protection model of the present utility model can not be limited with this
Enclose.
As shown in Fig. 2 a kind of TIR prism fixing device includes fixed pedestal 1, TIR prism 2, limit hook 5 and spacing spiral shell
Silk 6, fixed pedestal 1 is provided with fixed pedestal guide rail bar 7, and limit hook 5 is fixed on 7 in fixed pedestal guide rail bar, limited screw
On limit hook 5.
Limit hook 5 is fixed in fixed pedestal guide rail bar 7 by screw 9, and limit hook 5 is provided with screw 8, screw 8
Screw thread is provided with, the outside of fixed pedestal 1 is provided with fixed strip 4, as shown in figure 1, fixed strip 4 is screwed in fixed pedestal 1
On, sponge 3 is paid in the inner side of fixed pedestal 1 provided with pressure.
Fixed pedestal 1 is the ray machine carrier of TIR prism 2, and there is provided the anchor point coordinated with TIR prism 2 as shown in Figure 4；Pressure
Paying sponge 3 is used to eliminate the gap between fixed strip 4 and TIR prism 2, the free degree in restricted T IR prism 2Y directions；Such as Fig. 3 institutes
Show, limit hook 5 is slided along fixed pedestal guide rail bar 7, untill being contacted with TIR prism 2, restricted T IR prism 2Y direction of principal axis is certainly
By spending；Limited screw 6 is after limit hook 5 is adjusted in place, and rotation regulation limited screw 6 with TIR prism 2 untill contacting, point
Adhesive curing limited screw 6, the free degree of restricted T IR prism 2X direction of principal axis.Limit hook 5 is slided along the guide rail bar of fixed pedestal 1,
It is to be engaged with TIR prism 2, stress is applied to TIR prism 2, it is to avoid TIR prism divides because of stress.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
