[0025] Embodiments
[0026] AsFigures 1 to 4 As shown, the present invention proposes a visual communication rendering projection device, which includes a projector body 1 and a pair of groove mechanisms on both sides of the projector body 1, each groove mechanism having a handle 2 inside; and a fixing mechanism, which is set in the groove mechanism so that the handle 2 can be engaged or disengaged in the groove mechanism by pressing. The pair of groove mechanisms and the fixing mechanism are symmetrically arranged around the center of the projector body 1.
[0027] Furthermore, such as Figures 3 to 4 As shown, the groove mechanism includes slots 11 on both sides of the projector body 1. Each slot 11 has a pair of sliding grooves 12 inside. The projector body 1 also has telescopic grooves 13 communicating with the sliding grooves 12 inside its sides. Each telescopic groove 13 has a mounting groove 14 inside. A push spring 23 is installed inside the telescopic groove 13. The push spring 23 acts as a stop plate 22 to ensure it is not blocked by the L-shaped lifting block 26. It immediately causes the handle 2 to completely disengage from the slot 11 for the user to hold. One end of the push spring 23 is fixedly connected to the inner wall of the telescopic groove 13, and the other end is fixedly connected to the stop plate 22.
[0028] Furthermore, such as Figure 2 and Figure 4 As shown, the fixing mechanism includes an L-shaped support rod 28 fixedly connected inside the mounting groove 14. The L-shaped support rod 28 ensures that the L-shaped lifting block 26 slides vertically up and down. The L-shaped lifting block 26 is slidably connected to the upper part of the L-shaped support rod 28. The end of the abutment plate 22 near the L-shaped lifting block 26 is set as an arc end. The function of the arc end is to move the L-shaped lifting block 26 upward when the top of the abutment plate 22 abuts against the L-shaped lifting block 26. A second abutment block 29 is fixedly connected to the outer wall of the L-shaped lifting block 26. A pressing groove 15 is opened inside the mounting groove 14. A button 24 is slidably connected inside the pressing groove 15. A first abutment block 25 is fixedly connected to the end of the button 24 near the L-shaped lifting block 26 after abutting against the second abutment block 29. The connecting ends of the first abutment block 25 and the second abutment block 29 are provided with inclined surfaces that abut against each other. The inclined surfaces cause the second abutment block 29, which is abutted against by the end of the first abutment block 25, to move upward. The second abutment block 29 will eventually cause the L-shaped support rod 28 to be unable to jam the abutment plate 22. A return spring 27 is movably sleeved on the L-shaped support rod 28. One end of the return spring 27 is fixedly connected to the inner wall of the mounting groove 14, and the other end of the return spring 27 is fixedly connected to the L-shaped lifting block 26. A support slider 21 is slidably connected inside the slide groove 12. One end of the support slider 21 is fixedly connected to the handle 2, and the other end of the support slider 21 is fixedly connected to a stop plate 22 that moves the L-shaped lifting block 26 upward. The stop plate 22 moves the L-shaped lifting block 26 upward when it abuts against the bottom end of the L-shaped lifting block 26. The advantage is that it is quick and convenient to install the handle 2 in the slot 11.
[0029] In this embodiment, when the effect picture projection device for visual communication is needed to be used, as shown in Figure 1 pressing the button 24 into the pressing groove 15, one end of the button 24 drives the first abutting block 25 to abut against the second abutting block 29, so that the second abutting block 29 drives the L-shaped lifting block 26 to move upward along the L-shaped supporting rod 28. Until the bottom end of the L-shaped lifting block 26 cannot be clamped to the abutting plate 22, at this time, the abutting plate 22 drives the supporting sliding block 21 and the handle 2 to move through the elastic pushing force of the pushing spring 23 in the telescopic groove 13. When the handle 2 is completely out of the clamping groove 11, the handle 2 is pressed to the projection device body 1, and the supporting sliding block 21 and the abutting plate 22 are driven to move in the process of the handle 2, and the abutting plate 22 abuts against the bottom end of the L-shaped lifting block 26 to make the L-shaped lifting block 26 move upward. Until the handle 2 is completely clamped into the clamping groove 11, at this time, the bottom end of the L-shaped lifting block 26 is clamped into the abutting plate 22 through the elastic pushing force of the reset spring 27, so that the handle 2 cannot be out of the clamping groove 11. Finally, when the manually pressed button 24 is restored to the original position through the L-shaped lifting block 26, the L-shaped lifting block 26 drives the second abutting block 29 to abut against the first abutting block 25, and then the first abutting block 25 drives the button 24 to restore to the state of being completely clamped into the pressing groove 15.

The preferred embodiments do not describe all the details and do not limit the utility model to the specific implementation. Obviously, according to the content of the specification, many modifications and changes can be made. The specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that the persons skilled in the art can well understand and use the utility model. The utility model is limited by the claims and the whole scope and equivalents.
