Specific implementation mode

Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.

Referring to Fig.1 with shown in Fig. 4, a kind of projecting apparatus of angle adjustable provided in this embodiment include projector main body 1, Support leg 2 and spacer pin 4,2 one end of the support leg and the side plate 11 of projector main body 1 are hinged by a round pin 3, the side Sliding slot 12 there are one being set on plate 11, the sliding slot 12 is an arc groove gradually to broaden from top to bottom with round pin 3 for the center of circle, 12 head end of the sliding slot is in same level with the round pin 3, and 12 head end of the sliding slot is in same vertical with the round pin 3 Face, the spacer pin 4 are mounted in the support leg 2 and can be slided up and down in arc groove, i.e., the support leg 2 can be opposite The projector main body 1 rotates.

With reference to Fig. 2,2 one end of the support leg is set there are one the first pin hole 21, and intermediate position is equipped with second pin hole 22, The distance in 22 center of circle of the second pin hole to 21 center of circle of the first pin hole is equal to 12 radius of central line of sliding slot.

With reference to Fig. 3, the spacer pin 4 is multi-segment structure, includes the cylindrical installation of intermediate taper work section 41, right end Section 42, the radial limit section 44 of left end.The taper work section taper is 10 °, 41 left end diameter of the taper work section etc. In 12 head end width of the sliding slot, it is wide equal to 12 end of the sliding slot that right end diameter is equal to radial 44 diameter of section that limits Degree；The radial limit section 44 is for ensureing that the spacer pin 4 is not easily disconnected from the sliding slot 12；42 diameter of the construction section is equal to Second pin hole, 22 diameter, the spacer pin 4 can control being installed in the support leg 2 of translation by construction section 42.Institute The processing of 41 surface frosted of taper work section is stated, 4 right end of the spacer pin is additionally provided with a knob 43.

The projecting apparatus course of work and principle of the angle adjustable of the utility model are as follows:Referring to Fig.1, described when initial Projector main body 1 is horizontal positioned, and the spacer pin 4 is located at 12 the top of the sliding slot, and position relationship is as shown in figure 5, described Taper work section 41 contacts clamping with the sliding slot 12；Since sliding slot 12 is low wide and up narrow, when work, it is rotated down branch as needed Spike 2 is supported shown in 1 front end to Fig. 4 of the projector main body, is adjusted in place, and is turned left from the right side and is pressed the spacer pin 4 to figure Shown in 6, the taper work section 41 is contacted with the sliding slot 12 again by the right surface, when projecting apparatus is positioned over desktop, 1 bottom plate 13 of the projector main body is lifted to form an angle with desktop, under the action of 1 gravity of projector main body so that sliding slot 12 with 41 surface of taper work section forms frictional force and reaches the self-locking effect of spacer pin 4 and then realize the stabilization of support leg 2.In work, Because the gradual design of 12 width of sliding slot and the pyramidal structure of spacer pin 4 enable spacer pin 4 to be clamped on appointing for sliding slot 12 Meaning position, so projector main body 1 is lifted angle and can arbitrarily adjust in a certain range.

The utility model is matched by the spacer pin 4 with taper work face and the sliding slot 12 of width gradual change is applied so that is thrown Shadow instrument camera lens lifting angle can be adjusted arbitrarily in a certain range, and simple in structure, easy to use.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, Under every utility model in the utility model is conceived, equivalent structure made based on the specification and figures of the utility model Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
