Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum degree detection of vacuum glass, in particular to a vacuum degree detection device for vacuum glass. Background Art

[0002] In the field of modern architecture and high-end manufacturing, vacuum glass is becoming more and more popular due to its excellent sound insulation, heat insulation and thermal insulation performance. The core of vacuum glass lies in the high vacuum state maintained between its two pieces of glass, and the maintenance of this state directly determines the performance of vacuum glass. However, during the production and use process, ensuring and detecting the accuracy and consistency of the vacuum degree inside the vacuum glass is one of the key challenges in the production process. Traditional vacuum degree detection methods often involve complex equipment operation or cannot provide instant and accurate readings, which limits production efficiency and increases the difficulty of quality control.

[0003] In production practice, although some non-invasive detection methods such as surface temperature measurement and spectral analysis can provide certain vacuum information, they are limited by shortcomings such as low accuracy and the results are greatly affected by external factors, making it difficult to meet high-standard production detection needs.

[0004] Therefore, developing a device that can quickly, accurately and non-destructively detect the vacuum degree of vacuum glass on site is of great practical significance for improving the production efficiency and product quality of vacuum glass. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum glass vacuum degree detection device, which can be simply operated and quickly feedback the detection result through the combination of a barometer, a puncture needle, an adapter, etc., while ensuring that no damage is caused to the vacuum glass being tested, so as to meet the needs of modern and efficient production.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a vacuum glass vacuum degree detection device, comprising a pressure gauge, a puncture needle, an adapter and a support platform for horizontally placing the vacuum glass to be tested; the adapter comprises a three-way pipe; a first branch of the three-way pipe is connected to the pressure gauge; a second branch of the three-way pipe is connected to the puncture needle; a first ball valve and a second ball valve are respectively installed on the second branch and the third branch of the three-way pipe.

[0008] As a preferred technical solution of the utility model, the support platform includes a base plate; four columns are fixed on the upper surface of the base plate; an L-shaped limit seat is respectively fixed to the upper end of the two columns at one end of the base plate; a horizontal support plate pointing to the L-shaped limit seat is respectively fixed to the upper end of the other two columns; an L-shaped rubber pad is fixed to the inner side of the L-shaped limit seat; two parallel rubber plates are fixed to the upper surface of the horizontal support plate; and four threaded through holes are opened on the base plate.

[0009] As a preferred technical solution of the utility model, the horizontal support plate is provided with a T-shaped groove; a limited stopper is installed in the T-shaped groove.

[0010] As a preferred technical solution of the utility model, the limit stop seat includes a slider that slides with the T-shaped groove; a vertical plate is fixed on the slider; a bolt with a handle is threaded through the slider; a rubber sheet is fixed to one side of the vertical plate opposite to the L-shaped limit seat.

[0011] As a preferred technical solution of the utility model, the hollow pointed needle of the puncture needle is provided with at least two ventilation holes near the tip.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model directly reads the pressure change after the puncture needle enters the vacuum glass to be tested through the barometer, which can accurately determine the vacuum degree of the vacuum glass and improve the accuracy of the detection.

[0014] 2. The utility model combines the barometer, the puncture needle and the adapter, and the entire detection process is easy to operate. The detection can be carried out by simply aligning the puncture needle and puncturing it into the central part of the vacuum glass to be tested, which simplifies the operation steps and improves work efficiency.

[0015] 3. The design of the support platform of the utility model takes into account the protection of the vacuum glass to be tested. The damage to the glass is reduced by using buffer materials such as L-shaped rubber pads and rubber plates. At the same time, the limit stop can be adjusted and fixed to adapt to vacuum glasses of different sizes, thereby increasing the applicability of the equipment.

[0016] 4. After the detection of the utility model is completed, the puncture needle can be quickly pulled out and the puncture site can be re-sealed with structural adhesive, thereby avoiding the damage to the sealing performance of the vacuum glass due to the detection and ensuring the integrity of the product.

[0017] 5. The utility model uses a ball valve to control the gas flow, ensuring that the start and stop of the vacuum pump and the change of air pressure can be safely controlled during the detection process, avoiding safety accidents caused by improper operation.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
