Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a quick-release glass, including a glass main body 1. The glass main body 1 is used to display and protect the items or information in the display window, improve visibility, ensure that the information content can be easily seen from various angles and directions, and increase the exposure rate. An installation frame 2 for supporting the glass main body 1 is arranged outside the glass main body 1. An L-shaped baffle 3 for limiting the glass main body 1 and an arc-shaped pressing block 13 is fixedly connected to the inner wall of the installation frame 2. A fixing mechanism is arranged inside the installation frame 2. The fixing mechanism includes a knob 4. Anti-slip key patterns are arranged on the circumferential surface of the knob 4 to increase the friction between the palm and the knob 4 and reduce the possibility of slipping. A screw rod 5 is fixedly connected to the rear side of the knob 4. The screw rod 5 penetrates and is threadedly installed on the inner wall of the installation frame 2. When the knob 4 drives the screw rod 5 to rotate, the knob 4 will also move back and forth. A slot 20 is opened at the top of the installation frame 2. The glass main body 1 is inserted into the inner wall of the slot 20. The glass main body 1 is inserted or removed through the slot 20. A positioning mechanism is arranged on the front surface of the installation frame 2.

[0033] Refer to Figure 2 - Figure 4 , the fixing mechanism further includes a rotating rod 6. The rotating rod 6 is fixedly installed at the rear end of the screw rod 5. The screw rod 5 drives the rotating rod 6 to rotate. A convex block 9 is fixedly connected to the circumferential surface of the rotating rod 6. The number of the convex blocks 9 is set to be multiple groups. The multiple groups of convex blocks 9 are arranged at equal intervals in a ring on the circumferential surface of the rotating rod 6. The fixing mechanism further includes a circular plate 7. A control groove 8 is opened on the inner wall of the circular plate 7. The convex block 9 slides on the inner wall of the control groove 8. The rotating rod 6 slides on the inner wall of the circular plate 7. When the screw rod 5 drives the rotating rod 6 to rotate, the rotating rod 6 will also slide back and forth on the inner wall of the circular plate 7. At the same time, the convex block 9 will drive the circular plate 7 to rotate through the control groove 8. The fixing mechanism further includes a connecting rod 10. One end of the connecting rod 10 is hinged to a non-central position on the rear side surface of the circular plate 7. The other end of the connecting rod 10 is hinged to a sliding rod 11. The number of the sliding rods 11 is set to be two groups. The sliding rods 11 are slidably installed on the inner wall of the installation frame 2. Through the rotation of the circular plate 7, the circular plate 7 rotates to squeeze or pull the sliding rods 11 through the connecting rod 10, so that the sliding rods 11 move away from or close to each other. A U-shaped tube 12 is fixedly connected to the right side of the sliding rod 11. The fixing mechanism further includes an arc-shaped pressing block 13. The arc-shaped pressing block 13 is made of elastic rubber and can protect the glass main body 1 from being damaged when clamping the glass main body 1. The arc-shaped pressing block 13 is rotatably installed at one end of the U-shaped tube 12 away from the sliding rod 11. The arc-shaped pressing block 13 is elastically connected to the U-shaped tube 12 through a torsion spring 14. The torsion spring 14 makes the arc-shaped pressing block 13 have a tendency to rotate forward. The arc-shaped pressing block 13 contacts the L-shaped baffle 3.

[0034] Refer to Figure 5 - Figure 6The positioning mechanism includes a positioning rod 15 and a shell 16. The piston of the positioning rod 15 is installed on the inner wall of the shell 16. The front surface of the positioning rod 15 is provided with an arc surface. The positioning rod 15 is clamped in the positioning groove 19 to improve the stability of the glass body 1, avoid the deviation of the installation position of the glass body 1, and help to improve the precise control of the installation position of the glass body 1. The shell 16 is fixedly installed on the inner wall of the mounting frame 2. The positioning mechanism also includes a spring 17. One end of the spring 17 is fixedly installed on the rear surface of the positioning rod 15, and the other end of the spring 17 is fixedly installed on the front side of the inner wall of the shell 16. The spring 17 applies a force to the positioning rod 15. The elastic force toward the front side, the positioning mechanism also includes a vent hole 18, the vent hole 18 is opened on the rear side surface of the shell 16, the vent hole 18 connects the inside and outside of the shell 16, which is beneficial to the exchange of gas inside and outside the shell 16, the vent hole 18 has a small aperture, so that the air passes through the speed slower, so that the speed of the positioning rod 15 moving forward or backward will not be too fast, thereby improving the positioning accuracy and stability, and a positioning groove 19 matching the positioning rod 15 is opened on the back of the glass body 1. Through the cooperation of the positioning groove 19 and the positioning rod 15, the glass body 1 is more stable after installation, reducing the possibility of damage to the glass body 1 when it is squeezed.

[0035] Working principle: When in use, the glass body 1 is inserted into the mounting frame 2 through the slot 20. During the downward displacement of the glass body 1, the arc surface of the positioning rod 15 is squeezed, so that the positioning rod 15 overcomes the elastic force of the spring 17 and moves backward. When the positioning rod 15 contacts the rear surface of the glass body 1, the positioning rod 15 will not limit the downward displacement of the glass body 1. When the glass body 1 moves to the bottom and the positioning rod 15 is inserted into the positioning groove 19 and collides and produces a click sound, it indicates that the glass body 1 is installed in place. Then the knob 4 is turned. The rotation of the knob 4 drives the screw rod 5 to rotate. The rotation of the screw rod 5 drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 drives the circular plate 7 to rotate. The rotation of the circular plate 7 drives the two sets of sliding rods 11 to move closer to each other through the action of the connecting rod 10. The displacement of the rod 11 drives the displacement of the U-shaped tube 12, thereby causing the arc-shaped pressing block 13 to move toward the direction close to the L-shaped baffle plate 3. The L-shaped baffle plate 3 squeezes the arc-shaped pressing block 13, causing the arc-shaped pressing block 13 to overcome the elastic force of the torsion spring 14 and rotate backward. The rotation of the arc-shaped pressing block 13 will contact the front surface of the glass body 1 and apply a pre-tightening force to the glass body 1, thereby improving the stability of the glass body 1 installed inside the mounting frame 2. At the same time, due to the self-locking property of the screw 5, the arc-shaped pressing block 13 can maintain the pressure on the glass body 1 for a long time, thereby ensuring the installation quality of the glass body 1. When disassembling, the knob 4 is rotated in the direction to make the arc-shaped pressing block 13 break away from the contact with the glass body 1, and then the glass body 1 is pulled out upward, so that the glass body 1 can be conveniently and quickly taken out and replaced.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
