[0014] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0015] See also Figures 1-9 The present invention provides a technical solution: a pressure testing device for displaying glass structures, comprising a platform 1, five telescopic joints 2 are arranged above the platform 1, and support plates 3 are fixed to the upper ends of the five telescopic joints 2; A guide rail is fixed to one side of the platform 1, and a connecting plate 4 is slidably connected to the guide rail. A pin is fixed to one side of the connecting plate 4, and a pressure test chamber 5 is slidably connected to the outer side of the pin. A hydraulic plate 51 is slidably connected to the inner wall of the pressure test chamber 5. A pressure rod 52 is fixed below the hydraulic plate 51. The glass is laid flat on the support plate 3, and the glass structure is observed in a flat manner. The top of the pressure test chamber 5 is connected to the external hydraulic pump pipeline. The pressure rod 52 moves downward and contacts the glass surface; After the glass is laid flat on the support plate 3, the operator moves the connecting plate 4 to move the pressure test cavity 5 longitudinally on the guide rail, and at the same time moves the pressure test cavity 5 to move it laterally on the pin shaft, thereby adjusting the position of the pressure rod 52 to align it with the pressure test point of the glass. After the adjustment is completed, the external hydraulic pump is operated to inject liquid into the pressure test cavity 5. The pressure pushes the hydraulic plate 51 to slide downward along the inner wall of the pressure test cavity 5, and the pressure rod 52 moves downward and contacts the upper surface of the glass, applying pressure to the upper surface of the glass, thereby performing a pressure test on the glass. The pressure value that the glass withstands is calculated according to the pressure of the hydraulic pump. The test is convenient, and pressure testing can be performed on thicker or thinner glass, with a wide range of applications.

[0016] Four arc-shaped discs 6 are provided above the platform 1, wherein the four telescopic joints 2 are slidably connected to the four arc-shaped discs 6 respectively, and the middle telescopic joint 2 is slidably connected to the upper surface of the platform 1; Two guide pillars are fixed above the platform 1, and threaded discs 7 are slidably connected to the two guide pillars. A screw 71 is connected to the middle thread of the threaded disc 7. One end of the screw 71 is connected to a bearing on a slide rail 72. The support plates 3 are all slidably connected to the slide rail 72. Example 1: like Figure 7 As shown, the tested glass is relatively thin. The operator can rotate the screw 71 to make it pass through the threaded hole of the threaded disk 7 while rotating and moving to the right. During the movement, the screw 71 drives the slide rail 72 to move to the right. At this time, the support plate 3 is pulled to the right, driving the telescopic joint 2 to slide and move on the arc disk 6. At the same time, the support plate 3 slides on the slide rail 72, and the spacing between the support plates 3 is reduced. For thinner glass, the density of the support points at the bottom of the test point can be adjusted to avoid excessive force on the glass test point and insufficient support strength at the bottom, which may cause the glass to break, thereby protecting the glass. The spacing between the support plates 3 can be freely adjusted according to the test pressure set at the test point. The operation is convenient and efficient, and both thin and thick glass can be pressure tested quickly, efficiently and stably.

[0017] The four arc-shaped disks 6 are rotatably connected to the platform 1 and fixed by nuts; Example 2: like Figure 9As shown, the glass is extremely thin. At this time, the protection of the glass during the pressure test needs to be strengthened. At this time, after the telescopic joint 2 moves to the extreme position, it is restricted by the arc disk 6 and cannot move. At this time, the operator can loosen the nut to rotate the arc disk 6 to drive the telescopic joint 2 to continue moving, thereby further shortening the distance. There is no need to change the model of the arc disk 6, which reduces costs and enables the entire test device to support testing of any thin glass, with a wider range of applications.

[0018] A T-shaped block is fixed above the platform 1, and the T-shaped block is located on one side of the threaded disk 7. The outer side of the screw 71 is threadedly connected to a round block 711, which is located above the T-shaped block and the two are in contact with each other. One end of the round block 711 is in an arc shape. Example 3: When the tested glass is thin and the pressure rod 52 cannot contact the glass due to the movement distance, the operator can rotate the round block 711 to make it rotate and move on the screw 71. The left end of the round block 711 contacts the upper surface of the T-shaped block. As the round block 711 moves, it is gradually pushed upward by the T-shaped block, thereby driving the screw 71 to move upward. The screw 71 drives the threaded disk 7 to move upward through the guide column, and at the same time drives the support plate 3 to move upward through the slide rail 72, and pulls the telescopic joint 2 to extend, which can push up the thinner glass to avoid the failure of the pressure test. Whether it is the support point at the bottom of the glass or the position height, quick adjustment can be made, and the application range of the test glass is further expanded.

[0019] The T-shaped block includes a first block 81 and a second block 82. The first block 81 is fixed to the upper surface of the platform 1. One side of the second block 82 is in contact with one side of the threaded disk 7, and there is a gap between the first block 81 and the second block 82. A through hole is provided at the bottom of block one 81, and a support rod 821 is slidably connected in the through hole. A top block 9 is provided above the support rod 821, and a spring 10 is provided between the top of the top block 9 and the bottom of the second block 82. A sphere 822 is fixed to the outside of the support rod 821, and the sphere 822 is located below the top block 9, and the two are in contact with each other. A limit block is fixed to the bottom of the threaded disk 7, and one side of the limit block is in contact with one end of the top block 9. A card block 1 is fixed to the left side of the block one 81, and a card block 2 is fixed to the bottom of the block two 82, and the card block 2 is located below the card block 1, and the two are in contact with each other. Example 4: After the pressure applied by the pressure rod 52 to the glass reaches the set value, if the pressure needs to be further increased, the external hydraulic pump gradually increases the hydraulic pressure in the pressure test chamber 5 until the set test pressure value is reached. In order to protect the glass, the pressure of the pressure rod 52 on the glass is greater than the pressure of the spring 10 at this time, and the pressure applied to the block 2 82 through the round block 711 is less than the pressure of the external hydraulic pump. The spring 10 is deformed, and the block 2 82 slides downward between the threaded disk 7 and the block 1 81, so that the support plate 3 presses the telescopic joint 2 downward to shorten the glass, and the glass can be smoothly lowered in a small range to avoid the glass being crushed by the continuously increasing pressure, thereby protecting the glass, and reacting quickly and providing more timely protection.

[0020] There are several springs 10, and they are divided into different models according to the elastic force; Embodiment 5: The thickness of the glass is different, and the pressure during the test is different. At this time, in order to ensure the protection of the pressure test, you can take out the piece 2 82 and replace the spring 10. Select the model of spring 10 according to the test pressure value to adapt to different test pressures. It can protect the glass and ensure the smooth progress of the test.

[0021] A push rod 823 is fixed to the left end of the support rod 821, and both the front and rear ends of the push rod 823 are spherical. After the arc disk 6 rotates, it contacts the spherical part of the push rod 823, and the push rod 823 moves to the right.

[0022] A spring 2 11 is provided between the right side of the sphere 822 and the left side of the block 1 81; Example 6: like Figure 8 As shown, when the extremely thin glass is tested in Example 2, during the test, the pressure rod 52 has been pressed on the glass. At this time, the spacing between the support plates 3 is adjusted by rotating. At the same time, the arc disk 6 rotates and contacts the spherical part of the push rod 823, pushing the push rod 823 to the right. The push rod 823 drives the ball 822 to move to the right through the support rod 821 until the ball 822 is out of contact with the top block 9. The top block 9 is forced to drop rapidly, causing the block 82 to drop rapidly, so that the glass can drop instantly, and the pressure of the pressure rod 52 on the glass is instantly reduced, thereby protecting the extremely thin glass to the greatest extent. At the same time, when the support plate 3 moves, its upper end rubs against the bottom surface of the glass to avoid friction damage to the glass under high pressure, further protecting the extremely thin glass and fully avoiding its breakage or damage.
