Description

Technical Field

[0001] The utility model relates to the technical field of anti-glare panel testing, and particularly relates to a device for detecting the anti-deformation amount of an anti-glare panel. Background Art

[0002] Considering the usage scenarios of anti-glare panels, due to the strong wind outdoors and the disturbing effect of vehicles traveling at high speeds on the surrounding environment, anti-glare panels usually need to withstand large wind loads. Therefore, the anti-deformation amount of anti-glare panels is one of the important parameters for detecting their quality. Currently, the detection of the deformation amount of anti-glare panels is mainly carried out by laser projection.

[0003] For example: The technical solution disclosed in the patent document with the title "Device and Method for Detecting the Anti-deformation Amount of Anti-glare Panels by Laser Projection" (document number CN108955556A) is detected by a mechanical testing machine traction unit and an anti-glare panel anti-deformation amount detection unit. The mechanical testing machine traction unit is used to apply a horizontal traction force to the anti-glare panel. The anti-glare panel anti-deformation amount detection unit includes a gantry support frame, a pan-tilt head, a track, an electronic micrometer, and an infrared laser head. Using the laser projection method, by measuring the position difference between the projection points before and after the anti-glare panel is bent, the detection of the anti-deformation amount of the anti-glare panel is achieved.

[0004] In the prior art, in the method of using laser projection to detect the anti-deformation amount of anti-glare panels, affected by the height of the anti-glare panel itself, the laser projection device needs to be set at a relatively high position. The diameter of the punctuation point where the laser emitted by the laser projection device hits the projection surface is large. However, the anti-deformation amount test of the anti-glare panel requires accuracy to the millimeter level unit. Affected by the diameter of the laser point itself and it is difficult to measure. The measurement accuracy of the position difference between the initial and final projection points of the anti-glare panel is relatively low, resulting in a large error in the detection of the anti-deformation amount of the anti-glare panel. And as the height of the anti-glare panel under test increases, this error will increase accordingly. The prior art cannot solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to improve the detection accuracy of the anti-deformation amount of anti-glare panels, and a device for detecting the anti-deformation amount of anti-glare panels is provided.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A device for detecting the anti-deformation amount of an anti-glare panel, including a bench. An anti-glare panel with a vertical board surface is installed on the bench. One side of the anti-glare panel is used to be connected to a tensile testing machine. A column with an adjustable length is installed on the bench on the side of the anti-glare panel away from the tensile testing machine. The top of the column is hinged with a positioning plate with a horizontal board surface. A horizontally placed measuring ruler is arranged on the positioning plate. The suspended end of the measuring ruler extends towards the side where the tensile testing machine is located.

[0008] Further, a circular spirit level is arranged on the positioning plate.

[0009] Furthermore, the column comprises a column tube, the lower end of which is detachably mounted on the stand, a pole is inserted into the column tube, a thread is arranged on the pole, and the pole is threadedly matched with the column tube.

[0010] Furthermore, three length-adjustable support rods are evenly distributed along the circumferential direction on the upper part of the vertical rod, and the top ends of the support rods extend toward the lower plate surface of the positioning plate and form a contacting fit with the positioning plate.

[0011] Furthermore, each of the support rods includes an outer sleeve fixed on the column rod body, the outer sleeve is internally threadedly connected to an inner push rod, and the inner push rod is in contact with the bottom surface of the positioning plate.

[0012] Furthermore, a ring sleeve is rotatably provided at the top end of the column tube, and the vertical rod is threadably matched with the ring sleeve.

[0013] Furthermore, a base is provided at the lower end of the column, and the base is connected to the stand by bolts.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model changes the height of the column according to the height of the anti-glare board by adjusting the height of the column, so that the measuring ruler can measure the deformation of the anti-glare board at a close distance, and the detection accuracy will not be affected by the change of the height of the anti-glare board.

[0016] The measuring ruler on the top of the column of the utility model can be attached to the top of the anti-glare plate both before and after the anti-glare plate is bent under force, and the scale lines of the measuring ruler can accurately correspond to the measuring points corresponding to the top of the anti-glare plate. Compared with the traditional laser projection detection method, the influence of the laser point diameter is eliminated, and the measurement is more accurate.

[0017] The bottom surface of the positioning plate of the utility model is equipped with an adjustable support rod, which can be combined with a circular level bubble to adjust the horizontality of the positioning plate at any time. The positioning plate and the top of the column are hingedly connected through a ball head and a ball crown surface, so the positioning plate can be flexibly adjusted.

Detailed implementation manners

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and detailed implementation manners.

[0023] As Figures 1-3 shown, an anti-glare board anti-deformation amount detection device includes a bench 3. On the bench 3, an anti-glare board 1 with its board surface placed vertically is installed through a fixture seat 11 and bolts. One side of the anti-glare board 1 is used to connect with a tensile testing machine 2. On the bench 3 on the side of the anti-glare board 1 away from the tensile testing machine 2, a column 4 with adjustable length is installed. At the top of the column 4, a positioning plate 6 with its board surface placed horizontally is hinged (the positioning plate 6 and the top of the column 4 are hinged and connected through a ball head and a spherical crown surface). A horizontally placed measuring ruler 5 is fixed on the positioning plate 6. The suspended end of the measuring ruler 5 extends towards the side where the tensile testing machine 2 is located. A circular spirit level 7 is installed on the positioning plate 6.

[0024] The column 4 includes a column pipe 41. At the lower end of the column pipe 41, a base 10 is welded and fixed. The base 10 is installed on the bench 3 through bolts. A vertical rod 42 is inserted into the column pipe 41. Threads are provided on the vertical rod 42, and the vertical rod 42 is in threaded cooperation with the column pipe 41 to adjust the length of the column 4.

[0025] In this embodiment, as another preferred solution: A collar 9 is rotatably fitted at the top of the column pipe 41. The vertical rod 42 is in threaded cooperation with the collar 9 (the lower part inside the collar 9 is rotatably fitted with the top of the column pipe 41 through a bearing, and the upper part inside the collar 9 is in threaded cooperation with the vertical rod 42, and the vertical rod 42 can penetrate into the column pipe 41). In this solution, when adjusting the length of the column 4, the operator holds the vertical rod 42 still with one hand and rotates the collar 9 with the other hand. Under the threaded cooperation relationship between the collar 9 and the vertical rod 42, when the collar 9 rotates, the vertical rod 42 can rise or fall in the lumen of the column pipe 41, so as to be able to adjust the extended length of the vertical rod 42 in the column pipe 41, thereby realizing the height adjustment of the column 4.

[0026] In order to ensure that the surface of the positioning plate 6 is horizontal and does not change freely, three length-adjustable support rods 8 are arranged at equal intervals on the upper rod body of the vertical rod 42. The rod core of the support rod 8 is coplanar with the rod core of the column 4. The top of the support rod 8 extends to the lower surface of the positioning plate 6 and forms a contacting fit with the positioning plate 6. The support rod 8 includes an outer tube sleeve 81 welded and fixed on the rod body of the column 4. The outer tube sleeve 81 is internally threaded with an inner push rod 82, and the inner push rod 82 contacts the bottom surface of the positioning plate 6. The length of the support rod 8 can be adjusted by screwing the inner push rod 82. The support rod 8 is arranged in a triangle with the ball head as the center to resist the lower surface of the positioning plate 6, which can stabilize the positioning plate 6 and prevent it from moving freely, thereby ensuring the stability of the horizontal state of the positioning plate 6. Using the circular level bubble 7 as a reference, the positioning plate 6 and the measuring ruler 5 can be adjusted to a horizontal state, thereby ensuring that the measuring ruler 5 can be attached to the upper end surface of the anti-glare plate 1 in a relatively horizontal posture.

[0027] When measuring the anti-deformation amount of the anti-glare board 1, first, the lower end of the anti-glare board 1 is fixed to the stand 3 through the clamp seat 11, and the middle part of the anti-glare board 1 is connected to the tensile machine 2 by a traction rope. Figure 1 Then adjust the height of the column 4 so that the measuring ruler 5 is close to the upper end surface of the anti-glare plate 1 and read the corresponding reading on the measuring ruler 5 of the edge of the upper end surface of the anti-glare plate 1 away from the tensile machine 2, which is recorded as S0.

[0028] Then start the test tensile machine and apply horizontal traction to the anti-glare board 1 at a speed of 15mm / min. When the traction load reaches the wind load of the corresponding specification, stop the traction and remove the applied load to allow the anti-glare board 1 to recover freely and elastically. After 5 minutes, adjust the height of the column 4 so that the measuring ruler 5 is close to the upper end of the anti-glare board 1 again, and measure the reading corresponding to the same edge of the upper end surface of the anti-glare board 1 on the measuring ruler, which is recorded as S1.

[0029] The anti-deformation amount of the anti-glare plate 1 is calculated according to the following formula: R=(S1-S0) / H.

[0030] Wherein: R is the deformation resistance, the unit is millimeter per meter (mm / m); H is the height of the anti-glare board 1, the unit is meter (m).
