Problems solved by technology

[0004] Although the existing tilt adjustment system 18 is simple in design, it is extremely inconvenient for users. Therefore, it is often necessary to switch many turns of the threaded support rod 18R to make the front end of the projector 10 reach the desired tilt position.
Therefore, the height adjustment mechanism of the existing projector 10 is time-consuming and laborious in practical application, and there is a need for improvement.

Embodiment Construction

[0019] Please refer to image 3 , image 3 A front view of a projector 20 utilizing the height adjustment system 30 of the present invention is shown. Such as image 3 As shown, the height adjustment system 30 includes a height adjustment lever 40 and a latching mechanism 50 . The height adjustment rod 40 passes through the latch mechanism 50 , and through the mechanical action between the height adjustment rod 40 and the latch mechanism 50 , the height adjustment rod 40 is firmly locked at a predetermined position of the latch mechanism 50 . And when the user presses a button 50B, the height adjusting rod 40 is disengaged from the latch mechanism 50 and slides freely through the latch mechanism 50 . In this way, the distance D between the foot 42 of the height adjustment rod 40 and the lower edge surface 22 of the projector 20 can be adjusted freely, thereby adjusting the projection angle of the projector. Incidentally, the foot 42 may have a soft bottom surface with stro...

Abstract

The present invention provides a latch structure, including a hole-opened face through which a threaded bar can be passed, the half of hole-opened face has a smooth surface and a shell body can be fixed on it, and another half of said hole-opened face has thread and its fomed from an interior module, and said interior module can be slided in the shell body, and the interior module can be moved towards fixed portion of said hole-opened face by means of a spring. It also provides a button design for quickly regulating height and projector angle.

Description

technical field [0001] The invention relates to a height adjustment system, in particular to a height adjustment system which is applied in the field of projectors and can perform rapid rough adjustment and fine adjustment for a support foot. Background technique [0002] Please refer to figure 1 , figure 1 It is an existing projector 10 . The projector 10 is placed flat on a flat surface 12 , such as a flat desktop, and projects images onto a screen 14 . Since the height of the screen 14 relative to the projector 10 may vary, the projector 10 is generally provided with a set of tilt adjustment systems 18 for adjusting the projection angle θ of the projector 10 . to adjust the position of the image projected onto the screen 14 . [0003] Please refer to figure 2 , figure 2 show figure 1 Front view of the tilt adjustment system 18 of the middle projector 10. The existing tilt adjustment system 18 has two legs 18L, each leg 18L has a threaded support rod 18R, a foot ...
