Embodiment
For clearer, complete explanation the technical solution of the utility model, below in conjunction with the accompanying drawings to the utility model
It is described further.
Fig. 1, Fig. 2 are refer to, embodiment of the present utility model provides a kind of ray machine focusing structure of projecting apparatus
1, ray machine 2 is arranged in the drain pan 4 of projecting apparatus；The side of ray machine 2 is extended with a ray machine driving lever 3.
Fig. 1 is refer to, the side of the ray machine 2 is provided with a focusing structure 1；The focusing structure 1 is rotatably arranged on
In the drain pan 4 of projecting apparatus.Specifically, refer to Fig. 3, the focusing structure 1 includes a rotating shaft 11, the center of the rotating shaft 11
Provided with through hole 111；The periphery of the drain pan 4 is provided with mounting post (not shown) close to the position of ray machine driving lever 3；Described turn
Axle 11 is sheathed on the mounting post of drain pan 4, so that rotating shaft 11 is rotatably arranged on the drain pan 4 of projecting apparatus, so that described
Focusing structure 1 is rotatably on the drain pan 4 of projecting apparatus.
Fig. 3 is refer to, the focusing structure 1 also includes sliding guide groove 12；Fig. 1 is refer to, the sliding guide groove 12 is located at
In the semi-circumference of the remote ray machine 2 of rotating shaft 11, i.e., described sliding guide groove 12 is located at focusing structure 1 close to the outer of the side of ray machine 2
On circumference.Fig. 3 is refer to, bottom of the sliding guide groove 12 along focusing structure 1 diagonally extends to top；The sliding guide groove
12 are flexibly connected with the outer end of ray machine driving lever 3.
As can be seen here, when the focusing structure 1 is rotated relative to the drain pan 4, the sliding guide groove 12 also can be around peace
Fill post to rotate, so as to promote ray machine driving lever 3 to do reciprocating linear slip in sliding guide groove 12, so as to promote ray machine 2 to move forward and backward
To focus.
The utility model relative to drain pan 4 by focusing structure 1 by rotating setting, and the sliding guide groove 12 is tied along focusing
The periphery of structure 1 is extended obliquely out, so that the turning circumference motion of itself can be converted into ray machine driving lever 3 by the focusing structure 1
Linear motion.The utility model only needs to the focusing that a focusing structure 1 can be achieved with ray machine 2, therefore the ray machine focusing of this case
Structure 1 is simple, and assembling is simple, and cost is low.
Fig. 2 is refer to, the height of the sliding guide groove 12 gradually rises along the direction that ray machine 2 advances.As can be seen from Figure 3
The sliding guide groove 12 extends obliquely from the left-to-right of Fig. 3.Such design, when focusing structure 1 turns clockwise, ray machine
Driving lever 3 slides into the bottom of sliding guide groove 12；When 1 rotate counterclockwise of focusing structure, ray machine driving lever 3 slides into slip and led
The top of groove 12.
In the present embodiment, the rise angle of the sliding guide groove 12 is 45 degree.In other embodiments, the slip is led
Groove 12 can be 30 degree or 60 degree, and circular motion is converted into linear motion as long as can realize.
Fig. 3 is refer to, the focusing structure 1 also includes the focusing wheel 13 being fixedly connected with sliding guide groove 12；The focusing
Wheel 13 is in semicircle plate-like；Focusing wheel 13 is in the semi-circumference of the close ray machine 2 of rotating shaft 11.Specifically, the focusing wheel 13
Periphery is in dentation；The part of the focusing wheel 13 exposes to drain pan 4；The focusing wheel 13 is stirred for human hand so that focusing structure
1 rotates.13 parts of focusing wheel expose to drain pan 4, and its purpose of design is, user can just can be with the outside of drain pan 4
The operation focusing wheel 13, using very convenient.
In the present embodiment, the rotating shaft 11, sliding guide groove 12 and focusing 13 integrally connecteds of wheel.The design of integrally connected,
Just can be so that installation procedure is few, and cost is low so that need to only install a structure during installation of focusing structure 1；Integrally connect simultaneously
Connect so that the reliability of focusing structure 1 is added.
Fig. 4 is refer to, the side of the ray machine 2 is provided with a kidney slot 21；The kidney slot 21 is oblique in the side of ray machine 2
To extension；The outer end of the ray machine driving lever 3 is stretched out from kidney slot 21.
Specifically, the height of the kidney slot 21 gradually rises along the direction that ray machine 2 advances.Because the kidney slot 21 is
Extend obliquely out, when the ray machine driving lever 3 moves up and down, ray machine driving lever 3 can drive the ray machine 2 to move forward and backward,
So as to which the circular motion of the focusing structure 1 to be converted into the front and rear focusing movements of ray machine 2.
The ray machine focusing structure 1 of this case when in use, only need to lightly stir the portion that the focusing wheel 13 exposes drain pan 4
Point, so as to drive the up and down motion of ray machine driving lever 3, and then drive ray machine 2 to move forward and backward, to reach the purpose of focusing.
