Abstract
The utility model provides a structure is paid to projector's ultrashort burnt camera lens lock, includes compact heap, lower compact heap, its characterized in that: last compact heap, down the centre of compact heap connect the plane for arch form, the both ends of arch form, connection facade in plane has protrudingly on, have screw and locating hole on the plane of last compact heap under, the beneficial effects are that: with projector camera lens lock pay screw and the parallel direction of camera lens axis change into with camera lens axis vertically direction for the lock is paid the fastening of screw and is operated the influence that does not receive ultrashort burnt camera lens pre -group, and easy operation is convenient, has shortened the installation camera lens time, is favorable to batch production, and it is convenient that the camera lens installation is dismantled.
Description
Technical field
The utility model relates to a kind of scialyscope, be specifically related to the locking structure of the ultrashort focal length lens of a kind of scialyscope.
Background technology
At present, the general fixed form of projector lens is that camera lens is close to be positioned at being accurately positioned on face of light engine, then it is fastened on light engine fuselage (as shown in Figure 1) along camera lens axial lock key screw camera lens, but when using ultrashort focal length lens, because the external diameter of ultrashort zoom lens pre-group 6 can be bigger, when screwing locked screw 5 vertically, the most difficult operation because working place is not enough；Can not be made very big because of the space near volume relationship locked screw, therefore, locked screw typically all uses hexagon socket head cap screw, uses die nut to have some and a little screws locked screw, time consuming in operation, is unfavorable for bulk production simultaneously.
Summary of the invention
The purpose of this utility model is contemplated to overcome the deficiencies in the prior art, it is provided that a kind of scialyscope ultrashort zoom lens locking structure.
Technical solution adopted in the utility model is for achieving the above object: a kind of scialyscope ultrashort zoom lens locking structure, including upper compact heap, lower compact heap, it is characterized in that: described upper compact heap, the centre of lower compact heap are arch shape, the two ends of arch shape connect plane, plane connects facade, have projection on facade, upper compact heap, lower compact heap plane on have screw and location hole.Light engine fuselage there is lock pay screw and alignment pin.
A kind of scialyscope ultrashort zoom lens locking structure in accordance with the above, it is characterised in that: described upper compact heap is identical with the shape of lower compact heap.
This utility model provides the benefit that compared to existing technology: change direction parallel with lens axis for projector lens locked screw into the direction vertical with lens axis, the tightening operation making locked screw is not affected by ultrashort zoom lens pre-group, maintain camera lens positioning precision premise under simple to operation, shorten the installation camera lens time, be conducive to batch production, camera lens easy installation and removal.
Below in conjunction with the accompanying drawings this utility model is described further.

Detailed description of the invention
Accompanying drawing 1 is location and the fixed form schematic diagram of the ultrashort zoom lens of prior art scialyscope, ultrashort focal length lens 1 is positioned on light engine fuselage 2, position by locating surface 3 and locating dowel 4, fastening is paid by axial locked screw 5 lock, because camera lens pre-group 6 is bigger, the working place of locked screw is not enough, bit by bit screws with special spanner, extremely difficult.
Embodiment
Accompanying drawing 2 is the structural representation of this utility model embodiment, and Fig. 3 is the structure expanded view of Fig. 2, and Fig. 4 is the operation principle signal of this utility model embodiment；This utility model one scialyscope ultrashort zoom lens locking structure, including upper compact heap 7, lower compact heap 8, described upper compact heap 7, the centre of lower compact heap 8 are arch shape, the two ends of arch shape connect plane, plane connects facade 9, have projection 10 on facade 9, upper compact heap 7, lower compact heap 8 plane on have screw 11 and location hole 12, light engine fuselage 2 has lock pay screw 13 and an alignment pin 14.After ultrashort focal length lens 1 is arranged on light engine fuselage 2 by locating surface 3 and locating dowel 4 location, with compact heap 7 and lower compact heap 8, camera lens is pushed down, position by alignment pin 14,4 alignment pins 14 are had to position for upper compact heap 7 and lower compact heap 8 on fuselage, it is tightened in lock with locked screw 5 through screw 11 and pays in screw 13, the pressure of regulation locked screw 5, upper compact heap 7 and lower compact heap 8 facade 9 have projection 10 that camera lens locating surface 3 is applied pressure, and camera lens is positioned.Thus change direction parallel with lens axis for projector lens locked screw 5 into the direction vertical with lens axis, the tightening operation making locked screw is not affected by ultrashort zoom lens pre-group, maintain camera lens positioning precision premise under simple to operation, shorten the installation camera lens time, be conducive to batch production, camera lens easy installation and removal.
Above-described upper compact heap 7 and lower compact heap 8 shape are basically identical, are easy to processing and batch production, upper compact heap 7 and lower compact heap 8 can be made same shape.
Claims (2)
1. a scialyscope ultrashort zoom lens locking structure, including upper compact heap, lower compact heap, it is characterized in that: described upper compact heap, the centre of lower compact heap are arch shape, the two ends of arch shape connect plane, plane connects facade, have projection on facade, upper compact heap, lower compact heap plane on have screw and location hole.
A kind of scialyscope ultrashort zoom lens locking structure the most according to claim 1, it is characterised in that: described upper compact heap is identical with the shape of lower compact heap.
