Detailed implementation manners

[0035] Next, in combination with the drawings and the detailed implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 12 , the present invention provides a technical solution: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , it includes a penetration detection mechanism 1 for performing gas penetration test treatment on fireproof glass; a strength detection mechanism 2 for performing stamping and bending resistance detection on fireproof glass; The strength detection mechanism 2 is arranged on the penetration detection mechanism 1; Among them, the penetration detection mechanism 1 includes a penetration detection component 11 and a vertical rod 14. A limit plate 12 is arranged on the penetration detection component 11. The top of the vertical rod 14 is fixedly installed with a first track 15. A high-pressure chamber 16 is slidably fitted inside the first track 15. The high-pressure chamber 16 is used for filling a certain pressure of test gas into one end of the fireproof glass, and a booster 17 is fixedly installed on the top of the high-pressure chamber 16.

[0037] The penetration detection component 11 includes a hydraulic rod 31. At the top of the telescopic end of the hydraulic rod 31, a second track 32 is fixedly installed. The top of the second track 32 is fixedly connected to the limit plate 12. An electric push rod 33 is fixedly connected inside the second track 32. The output end of the electric push rod 33 is fixedly connected to a vacuum chamber 34, and the vacuum chamber 34 is slidably fitted inside the second track 32; The vacuum chamber 34 is used to reduce the other end of the fireproof glass to a low-pressure or vacuum environment, so as to calculate the gas penetration amount through the glass by measuring the change in the gas pressure on the low-pressure side within a certain period of time; A vacuum pump 35 is fixedly installed on the top of the vacuum chamber 34; Then, start the vacuum pump 35 and the booster 17 respectively. At this time, the vacuum pump 35 will construct the vacuum chamber 34 into a low-pressure or vacuum environment, while the booster 17 will fill the high-pressure chamber 16 with a test gas at a certain pressure. Finally, an external gas permeation meter is used to measure the change in the gas pressure on the low-pressure side within a certain period of time, and calculate the gas penetration amount through the glass.

[0038] A sealing flexible strip 36 is fixedly connected to the outside of the vacuum chamber 34. One end of the sealing flexible strip 36 away from the vacuum chamber 34 is fixedly connected to a detection piece 37. Among them, the sealing flexible strip 36 is used for sealing the vacuum environment and has a certain flexibility; Start the electric push rod 33 and make it contract. Since the number of electric push rods 33 is two, the vacuum chamber 34 and the high-pressure chamber 16 respectively connected to the output ends of the two electric push rods 33 will move in opposite directions towards both sides. Sealing flexible strips 36 are fixedly connected to the outside of both the vacuum chamber 34 and the high-pressure chamber 16. At this time, the sealing flexible strip 36 will block the openings of the vacuum chamber 34 and the high-pressure chamber 16. As the distance between the vacuum chamber 34 and the high-pressure chamber 16 increases, there will be a certain space for the fireproof glass to be placed between them. Then, restore the electric push rod 33 and make it extend. At this time, the vacuum chamber 34 and the high-pressure chamber 16 will move back towards the center, and both ends of the fireproof glass will squeeze the sealing flexible strip 36, causing both ends of the fireproof glass to be inserted into the vacuum chamber 34 and the high-pressure chamber 16 respectively. At the same time, the sealing flexible strip 36 will fit and seal with the upper and lower surfaces of the fireproof glass, thereby playing a role in clamping the fireproof glass and preparing for subsequent permeability detection.

[0039] Among them, the fireproof glass is the detection piece 37, and the upper and lower surfaces and the other two ends of the fireproof glass are all sealed to prevent gas from overflowing from the upper and lower surfaces and the other two ends during permeability detection, resulting in detection errors. In addition, the vacuum chamber 34 and the high-pressure chamber 16 not only play a role in detecting the permeability of the fireproof glass, but also play a role in supporting the fireproof glass.

[0040] A socket piece 38 is fixedly connected to the outside of the output end of the hydraulic rod 31. A compensation telescopic rod 39 is fixedly installed at the end of the socket piece 38 away from the hydraulic rod 31. The top of the compensation telescopic rod 39 is fixedly connected to a fitting block 30. The bottom of the fitting block 30 is squeezed and adapted to a top inclined plate 301, and the top inclined plate 301 is fixedly connected to the vacuum chamber 34. When the fireproof glass is clamped by the vacuum chamber 34 and the high-pressure chamber 16, the top inclined plate 301 no longer squeezes the fitting block 30, causing the fitting block 30 to disengage from the ball joint seat 303. At the same time, the compensation telescopic rod 39 will reset and contract. After the fireproof glass is detected, the vacuum chamber 34 and the high-pressure chamber 16 will move towards both sides. At this time, the fitting block 30 will be fitted with the bottom of the ball joint seat 303. When the two are fitted, the vacuum chamber 34 and the high-pressure chamber 16 still clamp the fireproof glass for processing.

[0041] A connecting sphere 302 is fixedly connected to the bottom of the detecting piece 37. A ball joint seat 303 is rotatably installed on the outside of the connecting sphere 302. The bottom of the ball joint seat 303 is fitted and adapted to the fitting block 30. When the vacuum chamber 34 and the high-pressure chamber 16 move outwards along the second track 32 and the first track 15 respectively, the top inclined plate 301 fixedly connected to the outside of the vacuum chamber 34 will move outwards accordingly. In addition, the inclined surface end of the top inclined plate 301 is squeezed and adapted to the bottom of the fitting block 30. Therefore, as the top inclined plate 301 moves outwards, the fitting block 30 will stretch the compensation telescopic rod 39 and move upwards, and finally be fitted with the bottom of the ball joint seat 303. A connecting sphere 302 is rotatably installed inside the ball joint seat 303, and there is a certain friction between the connecting sphere 302 and the ball joint seat 303. Therefore, the fireproof glass connected to the top of the connecting sphere 302 will not deflect automatically. In addition, the fitting block 30 serves to support the fireproof glass that has not yet been clamped in the vacuum chamber 34 and the high-pressure chamber 16.

[0042] A support assembly 13 is arranged beside the vertical rod 14. The support assembly 13 includes a support connecting frame 41. An air pipe 42 is fixedly installed inside the support connecting frame 41. An elastic strip is slidably fitted inside the air pipe 42. A first plug rod 43 is inserted into the bottom end of the air pipe 42, and the first plug rod 43 is fixedly connected to the bottom end of the elastic strip; The first plug rod 43 is closed with the air pipe 42, and a support plate 44 is fixedly connected to the end of the first plug rod 43 away from the air pipe 42; A bent rod 45 is inserted into the first track 15, and the top of the bent rod 45 is fixedly connected to the support plate 44. The support plate 44 is used to support the detecting piece 37 during the stamping detection process; A reset spring 46 is fixedly connected to the outer side of the bent rod 45, and one end of the reset spring 46 away from the bent rod 45 is fixedly connected to the outer side of the first track 15; wherein the bottom of the support plate 44 is fixedly connected with the bent rod 45, and the bent rod 45 is inserted into the first track 15. The bent rod 45 plays a role in supporting the support plate 44, and the reset spring 46 plays a role in resetting the support plate 44 and the bent rod 45.

[0043] The top end of the air pipe 42 is inserted with a second plug rod 47. The second plug rod 47 is fixedly connected to the top end of the elastic strip. One end of the second plug rod 47 away from the air pipe 42 is fixedly connected with an inclined block 49. A spring 48 is fixedly connected to the outer side of the inclined block 49. One end of the spring 48 away from the inclined block 49 is fixedly connected to the air pipe 42. By starting the second driving member 24, the stamping member 25 connected to its output end will move downward and perform a stamping test on the fireproof glass. A gravity ball 26 is arranged inside the stamping member 25, and the rod at the top of the stamping member 25 is detachable. Therefore, by changing the overall gravity of the stamping member 25, stamping tests can be performed on fireproof glasses of different thicknesses. Additionally, as the stamping member 25 moves downward, the triangular block 29 fixedly connected to its outer side will also move downward accordingly and squeeze the inclined block 49. The squeezed inclined block 49 will drive the second plug rod 47 to insert into the air pipe 42 and compress the spring 48. The spring 48 plays a role in resetting the second plug rod 47 and the inclined block 49. The other end of the second plug rod 47 is connected to the elastic strip, and the elastic strip is slidably fitted inside the air pipe 42. Therefore, the elastic strip will move towards the other end of the air pipe 42 and push the first plug rod 43 out of the air pipe 42. The other end of the first plug rod 43 is connected to the support plate 44. Therefore, the support plate 44 will move to the bottom of the fireproof glass and support it. Finally, the stamping member 25 will perform a stamping test on the fireproof glass. The support plate 44 plays a role in supporting the fireproof glass, and at the same time, the stamping member 25 can also be used to perform an extrusion test on the fireproof glass. At this time, the support plate 44 and the stamping member 25 play a role in double extrusion of the fireproof glass.

[0044] As Figure 11 and Figure 12 shown, the strength detection mechanism 2 includes a folding plate 21. The bottom end of the folding plate 21 is fixedly connected to the top of the first track 15. The top of the inner cavity of the folding plate 21 is fixedly connected with a first driving member 22. The output end of the first driving member 22 is fixedly connected with a central plate 23. The central plate 23 is used to perform a bending resistance test on the test piece 37. Additionally, by starting the first driving member 22, the central plate 23 connected to its output end will move downward and squeeze the center of the fireproof glass, thereby playing a role in performing a bending resistance test on the fireproof glass.

[0045] On both sides of the first driving member 22, second driving members 24 are symmetrically arranged. The second driving members 24 are fixedly installed at the top inside the folding plate 21. A stamping member 25 is fixedly installed at the output end of the second driving member 24. The stamping member 25 is used for detecting and processing the bearing strength of the test piece 37. A gravity ball 26 is arranged inside the stamping member 25. The top rod of the stamping member 25 is detachable, which is convenient for replacing the gravity ball 26. An inner rail 27 is provided inside the stamping member 25. A sliding plate 28 is slidably fitted inside the inner rail 27. The sliding plate 28 is used for adjusting the internal space of the stamping member 25. A triangular block 29 is fixedly connected to the outside of the stamping member 25. The bottom of the triangular block 29 is in extrusion fit with the inclined plane block 49. A rotating plate 20 is rotatably installed on the outside of the stamping member 25. A swinging hammer 201 is fixedly installed on the outside of the rotating plate 20. The bottom of the swinging hammer 201 is in extrusion fit with the limiting plate 12 and is used for detecting the pendulum impact of the test piece 37. A rotating plate 20 is rotatably installed on the outside of the stamping member 25, and a swinging hammer 201 is fixedly connected to the outside of the rotating plate 20. The swinging hammer 201 is limited by the limiting plate 12. However, when the hydraulic rod 31 is started and the second track 32 connected to its extending end moves downward, the limiting plate 12 fixedly connected to the top of the second track 32 will move downward accordingly. At this time, the fireproof glass clamped by the vacuum chamber 34 will be in an inclined state. And the downward movement of the limiting plate 12 causes it to no longer limit the swinging hammer 201, so as to utilize gravity to deflect the swinging hammer 201 and hammer and detect the fireproof glass in the inclined state.

[0046] When the present invention is in use: First, start the electric push rod 33 and make it contract. The number of electric push rods 33 is two. Therefore, the vacuum chamber 34 and the high-pressure chamber 16 respectively connected to the output ends of the two electric push rods 33 will move in opposite directions towards both sides. Sealing flexible strips 36 are fixedly connected to the outside of the vacuum chamber 34 and the high-pressure chamber 16. At this time, the sealing flexible strips 36 will block the openings of the vacuum chamber 34 and the high-pressure chamber 16. As the distance between the vacuum chamber 34 and the high-pressure chamber 16 is lengthened, there will be a certain space for the fireproof glass to be placed between them. Then, restore the electric push rod 33 and make it extend. At this time, the vacuum chamber 34 and the high-pressure chamber 16 will move towards the center again. The two ends of the fireproof glass will squeeze the sealing flexible strips 36, causing the two ends of the fireproof glass to be inserted into the vacuum chamber 34 and the high-pressure chamber 16 respectively. At the same time, the sealing flexible strips 36 will fit and seal with the upper and lower surfaces of the fireproof glass.

[0047] Subsequently, the vacuum pump 35 and the booster 17 are started respectively. At this time, the vacuum pump 35 will construct a low-pressure or vacuum environment in the vacuum chamber 34, while the booster 17 will fill the high-pressure chamber 16 with a test gas at a certain pressure. Finally, an external gas permeation meter is used to measure the change in the gas pressure on the low-pressure side within a certain period of time, and the gas permeation amount through the glass is calculated. When the vacuum chamber 34 and the high-pressure chamber 16 move outward along the second track 32 and the first track 15 respectively, the top inclined plate 301 fixedly connected to the outside of the vacuum chamber 34 will move outward accordingly. In addition, the inclined surface end of the top inclined plate 301 is pressed and adapted to the bottom of the fitting block 30. Therefore, as the top inclined plate 301 moves outward, the fitting block 30 will stretch the compensation telescopic rod 39 and move upward, and finally be fitted and adapted to the bottom of the ball joint seat 303 to perform preliminary support treatment on the fireproof glass.

[0048] By starting the second driving member 24, the stamping member 25 connected to its output end will move downward and perform stamping detection treatment on the fireproof glass. A gravity ball 26 is arranged inside the stamping member 25, and the rod at the top of the stamping member 25 is detachable. Therefore, the overall gravity of the stamping member 25 is changed to perform stamping detection treatment on fireproof glasses of different thicknesses. In addition, as the stamping member 25 moves downward, the triangular block 29 fixedly connected to its outside will also move downward accordingly and squeeze the inclined surface block 49. The squeezed inclined surface block 49 will drive the second insertion rod 47 to insert into the air pipe 42 and compress the spring 48. The spring 48 plays a role in resetting the second insertion rod 47 and the inclined surface block 49. The other end of the second insertion rod 47 is connected to an elastic strip, and the elastic strip is slidably fitted inside the air pipe 42. Therefore, the elastic strip will move towards the other end of the air pipe 42 and push the first insertion rod 43 out of the air pipe 42. The other end of the first insertion rod 43 is connected to the support plate 44. Therefore, the support plate 44 will move to the bottom of the fireproof glass and support it. Finally, the stamping member 25 will perform stamping detection treatment on the fireproof glass.

[0049] A rotating plate 20 is rotatably installed on the outer side of the stamping part 25, and a swing hammer 201 is fixedly connected to the outer side of the rotating plate 20. The swing hammer 201 is limited by a limiting plate 12. However, when the hydraulic rod 31 is started and the second track 32 connected to its extending end moves downward, the limiting plate 12 fixedly connected to the top of the second track 32 will move downward accordingly. At this time, the fireproof glass clamped by the vacuum chamber 34 will be in an inclined state. And the downward movement of the limiting plate 12 causes it to no longer limit the swing hammer 201. At this time, the swing hammer 201 deflects and hammers the fireproof glass in the inclined state for detection. In addition, by starting the first driving member 22, the center plate 23 connected to its output end will move downward and squeeze the center of the fireproof glass, so as to play a role in bending resistance detection of the fireproof glass.

[0050] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Those of ordinary skill in the art, starting from the above concept, without creative labor, all kinds of transformations made fall within the scope of protection of the present invention.
