Description

Technical Field

[0002] Fireproof glass is a special type of glass with fireproof properties. It can provide certain protection and delay the spread of fire when a fire occurs. There are many types of fireproof glass, including tempered fireproof glass, laminated fireproof glass and coated fireproof glass. The fire protection level required in different locations is different, and the thickness of the fireproof glass to be installed is also different. However, the thickness of traditional fireproof glass is mostly fixed and cannot be adjusted. As a result, the thickness of the glass cannot be adjusted according to the local fire protection level after leaving the factory, and its practicality is poor.

[0003] After searching, Chinese patent announcement number: CN212827243U discloses a thickness-controllable fireproof glass, comprising at least two pieces of glass and fireproof glue poured between adjacent pieces of glass, acid- and alkali-resistant butyl rubber strips are provided at the periphery between adjacent pieces of glass, and a cavity with a pouring port is formed between adjacent pieces of glass, fireproof glue is poured into the cavity, a spacer core is provided inside the butyl rubber strip, the spacer core is a metal core or a plastic core, and structural glue is injected around the periphery of the butyl rubber strip. The butyl rubber strip of the utility model is provided with a spacer core inside, and the spacer cores of uniform size ensure that the glass substrates are parallel to each other, thereby making the fireproof glue evenly distributed; by selecting spacer cores of different sizes, the distance between adjacent glass substrates can be controlled, thereby controlling the amount of fireproof glue in the cavity and obtaining different fire protection time.

When adjusting, the glass needs to be opened, then the spacer core is installed, and then the glass is installed. The operation is more troublesome and wastes a lot of time. Therefore, a thickness-controllable fireproof glass is proposed to solve the above problem. Utility Model Content

The adjustment component includes a cylinder 41. A threaded rod 42 is passed through and rotatably connected to the right surface of the cylinder 41. The threaded rod 42 is of existing technology and has self-locking properties. A positioning hole 401 is provided on the right surface of the threaded rod 42. A plum blossom screwdriver can be inserted into the positioning hole 401 to drive the threaded rod 42 to rotate. A disc 43 is threadedly connected to the outer wall of the threaded rod 42. When the threaded rod 42 rotates, the disc 43 is driven to move laterally. The left surface of the disc 43 is rotatably connected to a hollow tube 44. When the disc 43 rotates, it will not drive the hollow tube 44 to rotate.

[0033] Reference Figure 1 、 Figure 3 、 Figure 5 The cylinder 41 passes through and is fixedly connected to the right surface of the frame 1 to maintain stability. The positioning hole 401 is opened in a cross shape, and the hollow tube 44 passes through and slides on the left surface of the cylinder 41, sliding horizontally.

[0034] Reference Figure 1 、 Figure 3 、 Figure 5 The outer wall of the hollow tube 44 is made of rubber. The outer wall of the hollow tube 44 fits the cylinder 41 to maintain a seal and prevent air from leaking out. The threaded rod 42 passes through the right surface of the hollow tube 44.

[0035] Reference Figure 1 、 Figure 3 、 Figure 4 The adjustment component also includes a positioning block 45, the front surface of the positioning block 45 is fixedly connected to a T-shaped block 46, the positioning block 45 and the T-shaped block 46 will move synchronously, the front surface of the fireproof glass 2 is fixedly connected to a connecting plate 47, the front surface of the connecting plate 47 is provided with a T-shaped groove 402, the shape of the T-shaped groove 402 fits the T-shaped block 46.

[0036] Reference Figure 1 、 Figure 3 、 Figure 4The right surface of the positioning block 45 is fixedly connected to the left surface of the hollow tube 44. When the hollow tube 44 moves, it will push the positioning block 45 to move. The positioning block 45 is set to a trapezoidal shape, which is an isosceles trapezoid. When the positioning block 45 moves, it will squeeze the connecting plates 47 on the front and rear sides, causing the connecting plates 47 to move in the front and rear directions and open. The T-shaped block 46 is set to a T shape.

[0037] Reference Figure 1 、 Figure 3 、 Figure 4 There are two groups of connecting plates 47, fireproof glass 2, and T-shaped blocks 46, and two groups of T-shaped grooves 402 are opened. The two groups of connecting plates 47, fireproof glass 2, T-shaped blocks 46, and T-shaped grooves 402 are symmetrically distributed front and back with the center line of the frame 1. The T-shaped blocks 46 are slidably connected to the inner wall of the T-shaped groove 402. When the T-shaped blocks 46 move, they will drive the connecting plates 47 to move synchronously. The connecting plates 47 are set to be triangular.

[0038] Reference Figure 1 - Figure 3 The sealing assembly includes a rubber ring 33, a valve core 31 is provided on the right surface of the frame 1, and a one-way valve 32 is provided on the right surface of the frame 1. The valve core 31 and the one-way valve 32 are existing technologies and can be implemented by technicians in this field. Since they are existing technologies, they will not be described in detail in this case. A valve nozzle is provided on the valve core 31. When the valve nozzle is pressed, the valve core 31 can provide air circulation. The one-way valve 32 can only allow outside air to flow into the gap of the fireproof glass 2. After the nitrogen is discharged into the gap of the fireproof glass 2 from the one-way valve 32, the thermal insulation performance of the device can be enhanced.

[0039] Reference Figure 1 - Figure 3 The rubber ring 33 is fixedly connected to the outer wall of the fireproof glass 2, and the rubber ring 33 is slidably connected to the inner wall of the frame 1.

[0040] Working principle: When this device is in use, the distance between the two fireproof glasses 2 can be adjusted as needed, thereby changing the thickness of the overall device. If the distance between the fireproof glasses 2 needs to be expanded, first align the gas outlet of the nitrogen bottle with the one-way valve 32, and insert the plum blossom screwdriver into the positioning hole 401 to drive the threaded rod 42 to rotate. The rotating threaded rod 42 will drive the disc 43 and the hollow tube 44 to move to the left, and the hollow tube 44 moving to the left will push the positioning block 45 to move to the left. The positioning block 45 moving to the left will squeeze the inclined surface of the connecting plate 47, and the two groups of connecting plates 47 will move forward and backward to open, driving the two groups of fireproof glasses 2 to move forward and backward to open, and during the movement of the connecting plate 47, the T-shaped block 46 will also slide along the track of the T-shaped slot 402.

[0041] When the fireproof glass 2 is opened, in order to maintain the internal air pressure, the nitrogen in the nitrogen bottle will be sucked into the gap of the fireproof glass 2 through the one-way valve 32. The gap between the two groups of fireproof glass 2 will be filled with nitrogen, which can ensure the effect of heat insulation and fire prevention.

[0042] If you want to reduce the spacing between the fireproof glasses 2, first press the valve nozzle, and insert the plum blossom screwdriver into the positioning hole 401 to drive the threaded rod 42 to rotate in the opposite direction. The threaded rod 42 rotating in the opposite direction will drive the disc 43 and the hollow tube 44 to move to the right. The hollow tube 44 moving to the right will pull the positioning block 45 to move to the right. The positioning block 45 moving to the right will drive the T-shaped block 46 to slide in the opposite direction along the track of the T-shaped slot 402. The T-shaped block 46 will pull the connecting plate 47 toward the middle of the frame 1, and the connecting plate 47 will drive the fireproof glasses 2 to move together synchronously, thereby reducing the spacing between the fireproof glasses 2. When the fireproof glasses 2 move closer, the air inside will be squeezed out from the valve core 31.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
