Description

Technical Field

[0001] This utility model belongs to the field of glass testing technology and relates to a glass surface stress measuring device. Background Technology

[0002] Stress analyzers are used to quickly measure the surface stress distribution of photovoltaic glass, architectural flat glass, and automotive glass, and use scattered light to determine the internal stress distribution of annealed glass, semi-tempered glass, and tempered flat glass.

[0003] As disclosed in Publication No. CN309484377S, this portable intelligent stress analyzer, as prior art, emits a 5mW polarized laser beam that passes obliquely through a glass plate. To avoid light refraction, a glass prism is used, with a layer of refractive index fluid between the glass plate and the prism. Due to the photoelastic effect, the stress in the glass causes birefringence. The degree of birefringence is related to the stress distribution and the photoelastic constant of the material. During the measurement, the polarized laser beam is optically modulated by the birefringence caused by the internal stress of the glass and the modulator inside the SCALP to improve accuracy. The modulated laser beam is scattered on the glass (elastic Rayleigh scattering), and the intensity of the scattered light depends on the polarization state of the laser beam. During the measurement, the SCALP records the intensity change of the scattered light along the beam direction. From these data, the absolute optical phase difference at any point along the laser beam can be calculated, and the stress can be calculated from the gradient of the optical phase difference.

[0004] The existing technology has the following technical defects:

[0005] The stress analyzer described above needs to be pressed onto the glass during use and connected to a computer via a data cable for software analysis. The device cannot be moved during the analysis process. When testing and measuring pre-installed facade glass, personnel need to hold the device up and press it onto the glass while waiting for the computer software to complete the analysis, which is very inconvenient for high positions or when testing alone. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a glass surface stress measuring device.

[0007] The glass surface stress measuring device of this utility model includes a stress analyzer and a fixing plate. The fixing plate is provided with a placement port, a support block and a baffle corresponding to the stress analyzer. An elastic component is provided between the baffle and the fixing plate. A fixing component is provided at the bottom of the fixing plate.

[0008] The elastic component includes a tension spring fixedly connected to a fixed plate and a baffle. The tension spring has a guide post fixed to the fixed plate. The guide post is slidably connected to the baffle. A guide rod is fixedly connected to the support block. The baffle has a sliding groove adapted to the guide rod.

[0009] The fixing assembly includes a small suction cup fixedly connected to the rear of the bottom surface of the fixing plate and a large suction cup set at the front. The top of the large suction cup is provided with a connecting rod that penetrates the fixing plate. The top of the connecting rod is hinged to a suction cup pressure plate. The fixing plate is provided with a gripping handle.

[0010] The suction cup pressure plate has a protrusion at the top, which is higher than the top of the gripping handle.

[0011] The rear part of the fixing plate is split, and a semi-circular plate is movably connected to the fixing plate via a hinge. A small suction cup is fixedly connected to the bottom of the semi-circular plate.

[0012] The fixed plate and the semi-circular plate are each provided with a corresponding rubber groove on their opposite sides, and a rubber block is installed in the rubber groove.

[0013] The baffle is provided with a wire channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention allows the stress analyzer to be fixed on facade glass, inclined glass, or curved glass for testing, eliminating the need for manual hand-holding and pressing while waiting for the test results. This reduces the inaccuracy caused by manual operation. When testing glass at higher positions, simply fix the analyzer on the glass and wait for the test. This solves the problems of inconvenience for a single person to test the stress value of installed glass and the inability to test glass at higher positions. Attached Figure Description

Detailed Implementation

[0023] Example 1

[0024] like Figures 1-6 As shown, the glass 19 surface stress measuring device of this utility model includes a stress analyzer 16 and a fixing plate 1. The fixing plate 1 is provided with a placement port 12, a support block 8 and a baffle 5 corresponding to the stress analyzer 16. An elastic component is provided between the baffle 5 and the fixing plate 1. A fixing component is provided at the bottom of the fixing plate 1.

[0025] The elastic component includes a tension spring 9 fixedly connected to the fixed plate 1 and the baffle 5. The tension spring 9 has a guide post 10 fixed to the fixed plate 1. The guide post 10 is slidably connected to the baffle 5. A guide rod 20 is fixedly connected to the support block 8. The baffle 5 has a sliding groove adapted to the guide rod 20. In use, the stress analyzer 16 is placed at the placement port 12. Then, the detection liquid is applied to the detection head of the stress analyzer 16. After that, it is fixed to the glass 19 using the fixing component. Under the action of the baffle 5 and the tension spring 9, the stress analyzer 16 is tightly attached to the glass 19 and will not move, thereby detecting the stress of the glass 19. The stress analyzer 16 is prior art, and its specific reference model is SCALP-05 portable intelligent stress meter.

[0026] The fixing assembly includes a small suction cup 13 fixedly connected to the rear of the bottom surface of the fixing plate 1 and a large suction cup 11 set at the front. The top of the large suction cup 11 is provided with a connecting rod 18 that penetrates the fixing plate 1. The top of the connecting rod 18 is hinged to a suction cup pressure plate 2. The fixing plate 1 is provided with a gripping handle 3. By pressing the suction cup pressure plate 2, the connecting rod 18 is moved, thereby controlling the suction force of the large suction cup 11 on the glass 19. This structure is a relatively common existing technology that can achieve the adsorption of the glass 19.

[0027] The suction cup pressure plate 2 has a protrusion 17 on its top, which is higher than the top of the gripping handle 3. The protrusion 17 makes it convenient for the user to push it down and press it.

[0028] The rear of the fixing plate 1 is split. The fixing plate 1 is movably connected to the semi-circular plate 7 via the hinge 6. The small suction cup 13 is fixedly connected to the bottom of the semi-circular plate 7. When fixing, the small suction cup 13 of the semi-circular plate 7 can be pressed tightly onto the glass 19 first. The fixing plate 1 is rotated backward by the hinge 6, and then placed into the stress analyzer 16. After applying the detection liquid, the fixing plate 1 is pressed against the glass 19 by the handle and the suction cup pressure plate 2 to achieve adsorption, thereby fixing the stress analyzer 16.

[0029] The fixed plate 1 and the semicircular plate 7 are each provided with a corresponding rubber groove 14 on their opposite sides. A rubber block 15 is installed in the rubber groove 14. When the stress analyzer 16 is removed, since it is in contact with the baffle 5 and there is no fixed connection structure, the stress analyzer 16 may be suddenly ejected after the suction force of the large suction cup 11 is released under the action of the tension spring 9, which may cause it to fall. By installing the rubber block 15 at the hinge of the fixed plate 1 and the semicircular plate 7, the angle of natural swing of the fixed plate 1 and the semicircular plate 7 can be reduced under the action of the rubber block 15. Therefore, after the suction force of the large suction cup 11 is released, the supporting force of the rubber block 15 can relatively offset the tension force of the tension spring 9, preventing the fixed plate 1 from rotating suddenly, thereby avoiding the risk of the stress analyzer 16 falling.

[0030] The baffle 5 is provided with a cable groove 4, which allows the connecting cable to be passed through the cable groove 4 to connect to the computer during use.

[0031] This invention allows the stress analyzer 16 to be fixed on the facade glass 19, inclined glass 19, or curved glass 19 for testing, eliminating the need for manual hand-holding and pressing while waiting for the test results. This reduces the problem of inaccurate testing caused by manual operation. When testing glass 19 at higher positions, it is only necessary to fix the analyzer on the glass 19 and wait for the test. This solves the problems that it is inconvenient for a single person to test the stress value of the installed glass 19 and that glass 19 at higher positions cannot be tested.

[0032] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
