In this embodiment, a front frame plate 30 may be provided on the front surface of the frame 13, and the front frame plate 30 may have a strip-shaped hole 31 penetrating through the plate surface. A slide member 32 is connected to an outer side of the front frame plate 30, and the slide member 32 includes a rail plate 33 fixedly connected to the front frame plate 30 and a slide piece 34 slidably connected to the rail plate 33. In one embodiment, the sliding rail member 32 and the sliding piece 34 may be assembled together to form a sliding pair, wherein the sliding rail member 32 is a sheet metal member with inward grooves on both sides, and the sliding piece 34 is a sheet shape, and both sides of the sliding piece are correspondingly slidably fitted in the grooves of the sliding rail member 32, so as to achieve relative sliding. The slide member 32 may be provided with an opening for fixing it to the front frame plate 30 by a screw. The sliding plate 15 and the chute member 21 are respectively connected to both sides of the sliding piece 34 and correspond to the strip-shaped holes 31.
In this embodiment, the chute member 21 is located between the top and bottom surfaces of the bar hole 31. The slide groove member 21 is provided with left and right locking projections 35 and 36 at positions near the left and right ends of the top and bottom surfaces thereof, respectively. The left and right sides of the top surface and the bottom surface of the strip-shaped hole 31 are respectively provided with a left clamping groove 37 and a right clamping groove 38. When the sliding plate 15 drives the sliding channel member 21 to slide to the left limit position, the sliding channel member 21 is clamped in the left clamping groove 37 of the strip-shaped hole 31 through the left clamping protrusion 35. When the sliding plate 15 drives the sliding channel member 21 to slide to the right limit position, the sliding channel member 21 is clamped in the right clamping groove 38 of the strip-shaped hole 31 through the right clamping bulge 36. In this arrangement, the distance between the left and right click grooves 37, 38 is greater than the distance between the left and right click projections 35, 36 to allow the slide groove member 21 to slide in the first direction X1. In order to facilitate the left/right retaining protrusion 35/36 of the sliding chute member 21 to be retained in or slid out of the left/right retaining groove 37/38, two side surfaces of the left/right retaining protrusion 35/36 are smooth arc surfaces or inclined surfaces, and two side surfaces of the corresponding left/right retaining groove 37/38 are also smooth arc surfaces or inclined surfaces. In some embodiments, the slots of the left/right detent recesses 37, 38 may appear as spaces in front of the two adjacent ribs.
In this embodiment, the sliding piece 23 crosses the strip-shaped hole 31 in the second direction Y1 and is connected between the upper and lower edges of the front frame 30 through both ends thereof. The sliding part 28 comprises a sliding sleeve part 39 connected on the sliding piece 23 in a sliding way and a sliding block 40 fixedly connected with the inner side surface of the sliding sleeve part 39, the sliding block 40 is connected with one end of the supporting arm 24, and the front surface of the sliding block 40 is convexly provided with a boss 29. The slider member 39 has a through hole 41, the slider 23 has a through hole 42 extending in the second direction Y1, and the boss 29 is slidably fitted in the chute 22 after passing through the through hole 41 of the slider member 39 and the through hole 42 of the slider 23. Alternatively, the chute member 21 includes a plate-shaped chute plate 43 in which the chute 22 is opened and a coupling projection 44 coupled to a front surface of the chute plate 43. The projection passes through the strip hole 31 and abuts against the slide of the slide rail 32. The rear surface of the sliding plate 15 is provided with a convex hook 45, and the hook 45 passes through the through hole on the sliding plate and then is clamped in a clamping groove 46 formed on the convex block of the sliding groove piece 21, so that the sliding plate 15 and the sliding groove piece 21 are both connected on the sliding sheet 23. Thus, when the sliding plate 15 is slid, the sliding channel member 21 is slid along the first direction X1. During the sliding process, due to the cooperation of the inclined groove 22 and the boss 29 thereof, the movement along the first direction X1 will be converted into the movement along the second direction Y1 of the boss 29.
In this embodiment, the connection seat 47 is disposed at the stress point 20 of the air outlet cover 14, and the corresponding end of the support arm 24 is hinged to the connection seat 47.
The original angle of the torsion spring 27 in this embodiment is less than 180 °, and the two torsion legs 48 of the torsion spring 27 are respectively connected to the two arm sections 25 of the support arm 24, so that the two arm sections 25 are obliquely intersected when not being stressed. The original angle of the torsion spring 27 is the angle between the two legs 48 of the torsion spring 27 when no external force is applied to the torsion spring. The two arm sections 25 of the support arm 24 in this embodiment may be hingedly connected together by a pin, and the torsion spring 27 is fitted over the pin and abuts against the two arm sections 25 by its two torsion legs 48. The direction in which the torsion feet 48 abut against the arm sections 25 can be set as desired, so that elastic force transmission and movement between the two arm sections 25 are achieved. Due to the structure, even when an unexpected load is applied to the projector body 11 in a state where the outlet cover 14 is opened, the outlet cover 14 can be returned to the corresponding bottom frame plate 51 by overcoming the elastic force of the torsion spring 27, and the problem that the structure is damaged by the load, which may be caused by the conventional rigid support, is avoided.
In this embodiment, the air outlet cover 14 is located on the bottom surface of the frame 13, and the rotation axis 19 thereof is parallel to the intersection line of the front surface and the bottom surface of the frame 13, so that the air outlet cover 14 vertically or obliquely supports the front surface of the projector when being opened by rotating around the rotation axis 19. That is, the structure in this embodiment allows the air outlet cover 14 to also serve as a support foot for the projector.
The present invention provides a device having a linkage structure 12, which can be used for other devices (for example, a camera or other electric appliances required for heat dissipation) in addition to the projector 10 having the linkage structure. Only the device needs to have a linkage function, when the sliding plate 15 slides along the first direction, the sliding groove piece 21 slides along with the sliding plate, and the sliding groove piece 21 drives the boss 29 and the sliding piece 28 thereof to move in the second direction through the chute 22 on the sliding groove piece, and then the supporting arm 24 elastically supported by the elastic piece jacks the air outlet cover, so that the linkage of the two actions of sliding the sliding plate and opening the air outlet cover is realized.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
