Embodiment
The utility model embodiment provides a kind of catoptron adjustment structure, can carry out fine adjustments to the catoptron that is arranged in this catoptron adjustment structure.
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
Embodiment one
The utility model embodiment provides a kind of catoptron adjustment structure, comprises the support 1 that is used to hold catoptron 2,
Said support 1 is provided with at least one and is used for micromatic setting that said catoptron 2 is fixed in said support 1 and regulates said catoptron 2 and the relative position of said support 1.
Said micromatic setting can be fixed in catoptron 2 on the support 1; After the support 1 that is used to hold catoptron 2 fixed placement is in projector; Also can be arranged at least one micromatic setting on the said support 1, the relative position of accommodation reflex mirror 2 and support 1 through adjusting.
Need to prove; In embodiments of the present invention; If said catoptron 2 only is fixed in 1 last time of said support through a said micromatic setting; Can certain stationary installation be set everywhere what all the other of said catoptron 2 need be fixed, said stationary installation should make all being in certain scope of activities of said catoptron 2 everywhere, is convenient to said micromatic setting to the adjusting of said catoptron 2 with the relative position of said support 1.
Said micromatic setting can be arranged at the edge of said support 1, and the effect that regulate this moment is preferable, and can not influence the work of catoptron 2 so that the perform region of catoptron 2 maximizes.
Particularly; As shown in Figure 1; Said micromatic setting can be four; Said micromatic setting is arranged at four edges of said support 1 respectively, and said micromatic setting comprises and is used for said catoptron 2 is fixed in said support 1 and regulates a set screw 3 and a shell fragment 4 of said catoptron 2 and the relative position of said support 1;
Belong to the set screw 3 of a micromatic setting and the both sides that shell fragment 4 is arranged at an edge of support 1 respectively; But set screw 3 shell fragment 4 actings in conjunction corresponding with it push against catoptron 2 and then are fixed on the support 1, and can be through with set screw 3 precessions or screw out the relative position that support 1 comes accommodation reflex mirror 2 and said support 1.
As shown in Figure 2, said shell fragment 4 comprises being used for cooperating with said set screw 3 said catoptron 2 is fixed in said support 1 and regulates said catoptron 2 and touch portion 41 with the pressure of the relative position of said support 1 that said pressure is touched portion 41 and is provided with bending 411;
Because the pressure of shell fragment is touched portion 41 and is provided with bending 411, the pressure of shell fragment is touched portion 41 and is had elasticity preferably, and then set screw 3 is when precession or back-out support 1; The pressure of shell fragment is touched portion 41 and can be cooperated with set screw all the time and push against catoptron 2; Make this micromatic setting have fixed effect preferably, and then can be arranged at the set screw 3 of the diverse location on the support 1, reach the purpose of the relative position of accommodation reflex mirror 2 and said support 1 through precession or back-out; And because the pitch of set screw 3 can be selected according to actual conditions; Select hour when the pitch of set screw 3, set screw 3 whenever rotates a circle, and set screw 3 advance distance forward or backward is less; So also less to catoptron 2 with the regulating action of the relative position of support 1, can realize the fine adjustments of catoptron 2 with the relative position of support 1.
In general; Shell fragment 4 is to separate fabrication and processing with support 1; For shell fragment 4 is fixed on the support 1; As shown in Figure 2, said shell fragment 4 also comprises and is used for said shell fragment 4 is fixed in the fixed part 42 on the said support 1, and the fixed part 42 of said shell fragment is provided with the second shell fragment fixed orifice 421 that is used for fixing said shell fragment 4.
As shown in Figure 3, said support 1 is provided with the first shell fragment fixed orifice 11 that is used for fixing said shell fragment 4.
