Please refer to fig. 2 and 4, the inner side of the bevel gear ring 207 is engaged with the outer side of the bevel gear 216, the number of the U-shaped positioning frames 203 is plural, the plural U-shaped positioning frames 203 are distributed equidistantly along the central axis of the circular sleeve 202, the inner side of the moving block 206 is provided with a threaded hole engaged with the one-way screw 204, and the outer side of the guiding plate 215 is engaged with the inner side of the directional moving groove 219.

In this embodiment, when the bevel gear 216 drives the one-way screw 204 to rotate by setting up the structure, the moving block 206 limited by the directional moving groove 219 and the guide moving plate 215 moves along the one-way screw 204, so that the moving block 206 pushes the anti-skid fixed plate 205 to move, so that one end of the anti-skid fixed plate 205 is tightly attached to the outer side of the limit ball 201, the anti-skid fixed plate 205 extrudes the limit ball 201, friction between one end of the anti-skid fixed plate 205 and the limit ball 201 is increased, and the limit ball 201 is stably limited.

Please refer to fig. 1, 3 and 4, the fixed connecting component includes a movable cavity 222 disposed inside the limit rotating ring 214, the bottom of the limit rotating ring 214 is provided with a Z-shaped stay 208, the bottom of the Z-shaped stay 208 is welded and fixed with a worm wheel fixed ring 212 disposed outside the support pillar 211, the top of the mounting fixed plate 213 is connected with a support base 223, the inside of the support base 223 is rotatably connected with a positioning worm 209 through a rotating shaft, and two ends of the positioning worm 209 are connected with a rotating connecting rod 210.

In this embodiment, the rotating connecting rod 210 can be rotated after the projection angle of the exhibit projector body 1 is adjusted, when the rotating connecting rod 210 rotates, the positioning worm 209 can drive the Z-shaped stay 208 to rotate, so that the Z-shaped stay 208 can drive the limiting swivel 214, in this process, the swivel 217 can rotate relative to the supporting connecting rod 218 due to the rotation of the limiting swivel 214, so that the swivel 217 can limit the limiting swivel 214, thereby increasing the stability of the rotation of the limiting swivel 214, meanwhile, because the worm wheel fixing ring 212 cannot drive the positioning worm 209 to rotate, so that the Z-shaped stay 208 can stably drive the limiting swivel 214 to rotate, thereby providing convenience for the operation of the direction adjusting component.

Referring to fig. 3, the positioning worm 209 is engaged with the outer side of the worm wheel fixing ring 212, and the diameter of the inner wall of the worm wheel fixing ring 212 is larger than the distance from the supporting column 211 to the central axis of the circular sleeve 202.

In the embodiment, the positioning worm 209 is configured to rotate to drive the worm wheel fixed ring 212 to rotate, and meanwhile, the worm wheel fixed ring 212 is prevented from being worn by the supporting column 211 when rotating, so that the service lives of the worm wheel fixed ring 212 and the supporting column 211 are prolonged.

Please refer to fig. 2, the diameter of the insertion hole 220 is larger than the diameter of the one-way screw 204, the anti-skid fixed plate 205 is detachably connected with the moving block 206 through a bolt, and one end of the anti-skid fixed plate 205 is in a fit state with the outer side of the limiting ball 201.

In this embodiment, can prevent through setting up this structure that jack 220 from causing the hindrance to the removal of antiskid fixed plate 205, also prevent jack 220 and one-way lead screw 204 from taking place the friction simultaneously, the accessible takes off Z shape vaulting pole 208 and moves the bolt of being connected between the clamping piece 206 and take off antiskid fixed plate 205 fast after moving antiskid fixed plate 205 out of plugboard groove 221, thereby prevent that antiskid fixed plate 205 from causing wearing and tearing because of long-time the use, thereby prevent that antiskid fixed plate 205 from causing the influence to the spacing stability of spacing ball 201.

The utility model discloses a theory of operation is: after the projection angle of the exhibit projector body 1 is adjusted, the rotating link 210 can be rotated, when the rotating link 210 rotates, the positioning worm 209 can drive the Z-shaped stay 208 to rotate, so that the Z-shaped stay 208 can drive the limit swivel 214, in the process, the swivel 217 can rotate relative to the support link 218 due to the rotation of the limit swivel 214, so that the swivel 217 can limit the limit swivel 214, thereby increasing the stability of the rotation of the limit swivel 214, meanwhile, because the worm wheel fixed ring 212 can not drive the positioning worm 209 to rotate, so that the Z-shaped stay 208 can stably drive the limit swivel 214 to rotate, the limit swivel 214 can drive the bevel gear ring 207 to rotate, at the moment, the bevel gear ring 207 can rotate along the central axis of the circular sleeve 202 under the limit of the support link 218 and the swivel 217, so that the bevel gear ring 207 can stir the bevel gear 216 to rotate, therefore, the bevel gear 216 drives the one-way screw 204 to rotate, the moving block 206 limited by the guide moving plate 215 and the directional moving groove 219 moves towards the bevel gear 216 along the one-way screw 204, so that the moving block 206 drives the anti-skid fixed plate 205 to move, one end of the anti-skid fixed plate 205 is separated from the limit ball 201, the friction force of the anti-skid fixed plate 205 on the limit ball 201 is lost on the outer side of the limit ball 201, the exhibit projector main body 1 can be swung, the exhibit projector main body 1 can rotate in multiple directions relative to the circular sleeve 202, the irradiation angle of the projection lamp 3 can be adjusted, the picture angle projected onto the projection cloth by the exhibit projector main body 1 is adjusted, and the conical gear ring 207 can rotate through the bevel gear via the fixing and connecting component after the projection angle of the exhibit projector main body 1 is adjusted 216 drive one-way lead screw 204 and carry out the reverse movement, so just can make antiskid fixed plate 205 buckle in picture peg groove 221 under the promotion of moving card movable block 206 to this makes antiskid fixed plate 205's one end and the outside of spacing ball 201 extrude, thereby makes spacing ball 201 receive antiskid fixed plate 205's spacing, so as to make showpiece projector main part 1 stably place, whole process operation is simple, and the time spent is short, so that improve equipment's installation effectiveness, thereby improved visitor's the effect of visiting the showpiece.

The above description is only the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
