Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a digital film projector support, including support body 1, support body 1 includes fixed plate 11 and three landing leg 12 of rigid coupling in fixed plate 11 bottom, is provided with fixed box 2 on fixed plate 11, and 3 detachable of projectors are installed on fixed box 2.

Referring to fig. 2 and 3, fixed box 2 is cylindricly, and its top is for sealing, the bottom is uncovered, has seted up on the fixed plate 11 and has supplied fixed box 2 to follow male annular 13 down, has seted up screw thread on the lateral wall of annular 13, and fixed box 2's lower edge threaded connection is in annular 13, and the vertical rigid coupling in bottom of projector 3 has inserted post 31, and jack 21 has vertically been seted up on fixed box 2's top, and projector 3 is through inserting post 31 grafting cooperation on fixed box 2.

Referring to fig. 3, specifically, the insert column 31 is cylindrical, two sides of the bottom end of the insert column are horizontally and inwardly provided with limit grooves 32, limit blocks 33 are slidably connected in the limit grooves 32, and springs 34 are fixedly connected between the limit blocks 33 and the side walls of the limit grooves 32; the insertion hole 21 is in a circular truncated cone shape, the diameter of the insertion hole is gradually reduced from top to bottom, and the minimum diameter of the insertion hole 21 is the same as the diameter of the insertion column 31. In the process of inserting the column 31 and inserting the jack 21 for matching, the inner wall of the jack 21 can press the limit block 33, so that the limit block 33 is gradually retracted into the limit groove 32, after the limit block 33 passes through the jack 21, the spring 34 recovers deformation, the end parts of the two limit blocks 33 are popped out from the limit groove 32 on one side of each, and therefore limit is formed between the end parts and the top wall of the fixed box 2, and the installation of the projector 3 on the fixed box 2 is more stable.

Referring to fig. 3, the limiting block 33 can be designed to be a quarter fan shape, the position of the limiting block in contact with the inner wall of the jack 21 is an arc surface, and the arrangement of the arc surface can reduce the friction force between the limiting block 33 and the inner wall of the jack 21, so that the limiting block 33 can be automatically retracted into the limiting groove 32 smoothly in the installation process. Preferably, the stopper 33 is fixed with an anti-slip block 35 at an end inside the limiting groove 32, and the anti-slip block 35 is always slidably connected in the limiting groove 32 to limit the stopper 33 from accidentally slipping out of the limiting groove 32.

Referring to fig. 3, in order to prevent the free rotation of the projector 3 on the fixing box 2 during the projection process and affect the viewing effect of the viewers, a compression spring 4 is vertically and fixedly connected to the middle of the fixing plate 11, and a slot 5 is vertically and upwardly formed at the bottom end of the insertion column 31, when the projector 3 is mounted on the fixing box 2, the compression spring 4 can elastically abut against the slot 5, so that the lens of the projector 3 can be rotated to adjust the projection angle under the condition of artificially applying an external force.

The vertical height of the upper edge of the stopper 33 from the lower surface of the projector 3 should be the same as the thickness of the top wall of the fixed box 2, and when the stopper 33 is ejected from the stopper groove 32 to form a stopper with the fixed box 2, the lower surface of the projector 3 can abut against the top surface of the fixed box 2, so that the placement of the projector 3 can be stabilized.

Referring to fig. 1, the preferred, vertically seted up anti-skidding line 22 on the outer peripheral face of fixed box 2, anti-skidding line 22 can increase the frictional force between palm and the fixed box 2, when needs take off projector 3 from support body 1, can follow annular 13 internal screw-out with fixed box 2 earlier, then press the spacing groove 32 with stopper 33 through the finger in, will insert post 31 last upwards release fixed box 2 can, the operation is comparatively convenient simple.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
