Existing most of projector equipment is all to arrange an opening in the corresponding position that appearance is case top, directly
Connect and the Zoom structure of projection lens such as zoom lever itself exposed, or the governor motion that Zoom structure is transferred for example with
The zoom ring that zoom lever connects exposes, to realize the zooming adjustment of projector equipment.However, Zoom structure directly exposes projector equipment
On the one hand design outside housing easily causes the maloperation of user, the stability of impact projected picture, on the other hand corresponds to and becomes
Also external to the appearance design of the projector equipment housing restriction necessarily of the open design of close-burning structure.In consideration of it, this utility model
Embodiment provides a kind of Zoom regulating mechanism, and by the adjusting position of Zoom structure, that is, the adjusting position of zoom lever is by lens barrel
The front end of lens barrel has been transferred at middle part, and Zoom regulating mechanism has been hidden in the housing of projector.
First embodiment
The Zoom regulating mechanism that this utility model embodiment provides, is applied to projector.Projector includes projection lens, throws
It is provided with zoom lever on shadow camera lens, for the zooming adjustment of projection lens, can adjust projection lens by stirring zoom lever
Focal length.
Fig. 1 shows the solid after the Zoom regulating mechanism and projection lens assembling that this utility model first embodiment provides
Schematic diagram.Fig. 2 shows the section after the Zoom regulating mechanism and projection lens assembling that this utility model first embodiment provides
Schematic diagram.As depicted in figs. 1 and 2, in the present embodiment, Zoom regulating mechanism includes cylinder 120, and this cylinder 120 is set in projection
Outside the lens barrel 113 of camera lens 110, and the zoom lever 112 of projection lens 110 is connected with the side wall of cylinder 120.That is, circle
Cylinder 120 can rotate with respect to lens barrel 113, and the rotation of cylinder 120 can drive zoom lever 112 to rotate, thus adjusting projection
The focal length of camera lens 110.
Specifically, the end face of the side of the light-emitting window 111 of the close projection lens 110 of cylinder 120 is defined as outer face
124.First opening 123 is had on described outer face 124.Additionally, for the ease of the regulation of cylinder 120, on described outer face 124 also
It is provided with adjustment part 121, for driving described cylinder 120 to rotate.It is understood that adjustment part 121 is located at first
Between the outer wall of opening 123 and cylinder 120.As shown in figure 3, because the side wall of cylinder 120 has certain thickness, cylinder 120
Outer face 124 be shaped as annular, described adjustment part 121 is arranged in annular region.Now, the tune of zoom lever 112
The front end of lens barrel 113 has been transferred in section position by the middle part of lens barrel 113, that is, at the outer face 124 of cylinder 120.
First opening 123 is used for the light by projection lens 110 outgoing, in the present embodiment, the shape of the first opening 123 with
The shape of the light-emitting window 111 of projection lens 110 is consistent.As shown in Figure 3.Under normal circumstances, projection lens 110 light-emitting window 111
Generally circular in shape, therefore, the shape of the first opening 123 is preferably also circle.Certainly, the first opening 123 can also adopt other
Shape, for example square.Setting in order to avoid cylinder 120 impacts to normal use of projection lens 110, when the first opening
When 123 shape is consistent with the shape of the light-emitting window 111 of projection lens 110, the size of the first opening 123 can be more than or equal to
The size of the light-emitting window 111 of projection lens 110.Shape when the light-emitting window 111 of shape and the projection lens 110 of the first opening 123
When shape is inconsistent, then the size of the first opening 123 should be more than the size of the light-emitting window 111 of projection lens 110, and projection lens
110 light-emitting window 111 is revealed in the first opening 123 completely.
Specifically, in one kind preferably embodiment of the present embodiment, adjustment part 121 can be opened for being arranged on first
The adjustment hole on end face between mouth 123 and the outer wall of cylinder 120, as shown in Figure 3.By an adjusting rod being independently arranged,

Interior, thus stirring cylinder 120 with respect to lens barrel 113 along clockwise direction or rotationally clockwise.Due to projection lens 110
Zoom lever 112 is connected with the side wall of cylinder 120, and therefore, the rotation of cylinder 120 also drives the rotation of zoom lever 112 simultaneously, thus
Realize the regulation of projection lens 110 focal length.
It should be noted that above-mentioned adjustment hole can be cylinder 120 side wall outer face 124 on processing there is a depthkeeping
The hole of degree or integrally formed with the outer face 124 of cylinder 120 side wall or sweat soldering groove.
In addition, in a kind of embodiment of the present embodiment, adjustment part 121 can also be for being arranged on the first opening
The projection on end face between 123 and the outer wall of cylinder 120.By an adjusting rod being independently arranged, coordinate with projection, permissible
Adjust cylinder 120 to rotate with respect to lens barrel 113.Now, at least one end of adjusting rod is provided with one and is mated with above-mentioned projection
Groove.During use, projection is snapped in groove, you can with by adjusting rod rotating cylinder 120 so that cylinder 120 is with respect to mirror
Cylinder 113 along clockwise direction or rotationally clockwise, realizes the regulation of projection lens 110 focal length.
Further, the side wall of cylinder 120 can be for being detachably connected with the connected mode of zoom lever 112.As Fig. 1 institute
Show, in one kind preferably embodiment of the present embodiment, the side wall of cylinder 120 is provided with spacing hole 122, zoom lever 112 with
Spacing hole 122 clamping, that is, zoom lever 112 snap in spacing hole 122.Certainly, the set location of above-mentioned spacing hole 122 corresponds to and becomes
The position of burnt bar 112.In order to ensure the compactness being connected between the side wall of cylinder 120 and zoom lever 112, zoom lever 112 and limit
Position can be interference fit between hole 122.
Certainly, the side wall of cylinder 120 can also be for being fixedly connected with the connected mode of zoom lever 112.For example, cylinder 120
Side wall and zoom lever 112 sweat soldering, easy to process, with low cost, stable connection.
Further, rotate with respect to lens barrel 113 for the ease of adjusting cylinder 120, can be in the inwall of cylinder 120 and throwing
Grease is filled between lens barrel 113 outer wall of shadow camera lens 110.Grease has reduction mechanical friction, reduces the work of mechanical wear
With being conducive to improving the operability of this Zoom regulating mechanism.
In sum, the Zoom regulating mechanism that this utility model embodiment provides includes the cylinder being set in outside lens barrel 113,
Cylinder is connected with the zoom lever 112 of projection lens 110, the end setting of the light-emitting window 111 of the close projection lens 110 of cylinder
There is adjustment part 121, during use, drive cylinder to rotate with respect to lens barrel 113 by stirring adjustment part 121, and then drive change
Burnt bar 112 rotates, and realizes the zooming adjustment of projection lens 110.Compared with the existing Zoom regulating mechanism being applied to projector,
The Zoom regulating mechanism that this utility model embodiment provides is effectively by the adjusting position of Zoom structure, the i.e. tune of zoom lever 112
The front end of lens barrel 113 has been transferred in section position by the middle part of lens barrel 113, that is, at the outer face 124 of cylinder 120.Wherein, lens barrel
113 front end is specially the end face outside towards projector of lens barrel 113.Therefore, when being applied to projector, this utility model is real
The Zoom regulating mechanism applying example offer can be hidden in the enclosure interior of projector, improve Zoom regulating mechanism and expose to projection
The problem of easy maloperation and the problem of impact projector housing appearance design that the case top of instrument is brought.
