Description

Technical Field

[0001] This utility model relates to the field of tempered glass measurement technology, specifically a tempered glass measuring device. Background Technology

[0002] Tempered glass is glass that has undergone heat treatment. Its characteristic is that a compressive stress layer is formed on the glass surface, which improves its mechanical strength and thermal shock resistance, and gives it a special fragmentation pattern. Tempered glass is a type of safety glass and is widely used in places where mechanical strength and safety requirements are high. It can be used alone or made into laminated or insulated products as needed. After the tempered glass is processed and produced, it is necessary to use measuring devices to measure the dimensional compliance rate of the tempered glass.

[0003] The published patent document CN217520393U discloses a measuring device for measuring the dimensions of tempered glass. This patent document describes a device that allows workers to attach a first sleeve to the tempered glass using a connecting frame. By tightening bolts, the tempered glass is fixed between the pressure plate and the sleeve. A ruler can then be pulled to measure the dimensions of the tempered glass. The dimensions are recorded in one measurement by checking both the ruler and the scale. This method is simple and convenient for workers, eliminating the need for separate measurements. However, the published patent document cannot detect the flatness of the tempered glass edges, thus failing to measure the side areas where the tempered glass length changes, resulting in poor measurement accuracy.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-2 This utility model provides a tempered glass measuring device, including two outer rulers 1. Each outer ruler 1 has a sliding groove 2 on its opposite side. A matching inner ruler 3 is slidably connected inside the sliding groove 2. An L-shaped piece 4 is fixedly installed at one end of the inner ruler 3 outside the sliding groove 2. A groove 9 is provided on the L-shaped piece 4. Support rods 10 are fixedly connected to the upper and lower parts of the front and rear sides of the L-shaped piece 4. A rotating shaft 11 is rotatably installed inside the groove 9. A roller 13 is sleeved and fixedly connected on the rotating shaft 11. A rotating shaft 2 12 is rotatably installed between the two vertical support rods 10. A roller 2 14 is sleeved and fixedly connected on the rotating shaft 2 12. The end of the inner ruler 3 and the side of the roller 13 and the roller 2 14 are all in the same vertical plane. In this technical solution, the inner rulers 3 are slid along the slide groove 2 until the ends of the two inner rulers 3 are flush with the two sides of the width of the tempered glass. Then, the measuring device is moved downward so that rollers 13 and 14 contact the two sides of the width of the tempered glass. Then, the measuring device is moved along the length of the tempered glass. When there is an area where the width of the tempered glass increases, rollers 13 and 14 on both sides cannot continue to roll. When there is an area where the width of the tempered glass decreases, rollers 13 and 14 on both sides will move downward. This allows for the detection of the flatness of the tempered glass edge, resulting in better measurement results.

[0017] In some technical solutions, such as Figure 1 and Figure 3As shown, each of the two outer rulers 1 has a connecting lug 15 fixedly connected to its adjacent side. A rotating shaft 16 passes through the two connecting lugs 15. The rotating shaft 16 is fixedly connected to one connecting lug 15 and rotatably connected to the other connecting lug 15. A positioning member 17 is fixedly connected to the front end of the rotating shaft 16. Threaded holes 19 are provided on both sides of the positioning member 17. A positioning thread 18 that matches the threaded hole 19 passes through and is threaded onto the outer ruler 1. The front end of the positioning thread 18 passes through the threaded hole 19.

[0018] In use, by unscrewing the positioning thread 18 from the threaded hole 19, the two connecting ears 15 can be rotated with the pivot 16 as the center, thereby rotating the two outer scales 1, which makes it easy to unfold and fold the measuring device, making it convenient to use.

[0019] In some technical solutions, such as Figure 1 and Figure 4 As shown, the inner ruler 3 has a threaded groove 21 on the top of one side inside the slide groove 2. The threaded groove 21 is connected to a matching fixing bolt 8. The top of the outer ruler 1 has a through hole 7 that matches the fixing bolt 8. The through hole 7 communicates with the interior of the outer ruler 1, and the fixing bolt 8 passes through the through hole 7.

[0020] In use, the lower end of the fixing bolt 8 is moved towards the bottom of the threaded groove 21 by rotating the fixing bolt 8 until the upper part of the fixing bolt 8 abuts against the top of the outer ruler 1, thereby fixing the inner ruler 3 in the slide groove 2 and ensuring the accuracy of flatness detection at the edge of tempered glass.

[0021] In some technical solutions, such as Figure 1 As shown, the front side of the outer ruler 1 is provided with a scale mark 5, and the front side of the slide groove 2 is provided with a scale mark 6.

[0022] When in use, the length of tempered glass can be measured using scale mark 5 and scale mark 6.

[0023] In some technical solutions, such as Figure 3 As shown, a hanging ring 20 is fixedly connected to the top of the positioning component 17.

[0024] When in use, the hanging ring 20 facilitates the hanging of the measuring device after it is folded.

[0025] In some technical solutions, such as Figure 4 As shown, a matching washer 22 is fitted on the fixing bolt 8.

[0026] When in use, the inner ruler 3 is fixed with the fixing bolt 8 by means of the shim 22, which increases the friction between it and the outer ruler 1.

[0027] Working principle: During use, the inner rulers 3 slide along the groove 2 until the ends of the two inner rulers 3 are flush with the two sides of the width of the tempered glass. The length of the tempered glass can be measured by the scale marks 5 and 6. Then, the measuring device is moved downward so that the rollers 13 and 14 contact the two sides of the width of the tempered glass. Then, the measuring device is moved along the length of the tempered glass. When there is an area where the width of the tempered glass increases, the rollers 13 and 14 on both sides can no longer roll. When there is an area where the width of the tempered glass decreases, the rollers 13 and 14 on both sides will move downward. This allows for the detection of the flatness of the edge of the tempered glass. When the measuring device is not in use, the positioning thread 18 is unscrewed from the threaded hole 19. The two connecting ears 15 can be rotated with the pivot 3 16 as the center, thereby rotating the two outer rulers 1. This facilitates the unfolding and folding of the measuring device.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
