Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass strength testing, in particular to a tempered glass strength testing device. Background Technique

[0002] Tempered glass strength testing is an important means to evaluate its mechanical properties such as impact resistance, bending resistance, and compressive resistance, ensuring its sufficient safety, stability, and durability in practical applications.

[0003] In the existing operation of tempered glass strength testing, commonly, the tempered glass to be tested is placed on the front side of the test channel, and then a heavy object is placed into the channel. The heavy object freely falls from a preset height and hits the tempered glass to test the strength of the tempered glass. Or the tempered glass sample is placed flat on the press platform, and a uniform vertical pressure is gradually applied until it breaks. Record the maximum pressure at the time of breakage to evaluate the compressive strength of the glass, etc. However, when testing tempered glass, some testing devices do not fix the tempered glass, resulting in the tempered glass bouncing out of the test area when the heavy object falls, or using a screw clamping and locking method to fix the tempered glass, and the clamping force of the screw is uneven, resulting in the unstable structure of the tempered glass when it is impacted, affecting the accuracy of the test data.

[0004] Therefore, a tempered glass strength testing device has now been developed that can avoid affecting the self-structure of the tempered glass, reduce the difficulty of fixing the tempered glass, and improve the test efficiency and data accuracy. Summary of the Invention

[0005] In order to overcome the shortcomings in the above background technique, the utility model provides a tempered glass strength testing device that can avoid affecting the self-structure of the tempered glass, reduce the difficulty of fixing the tempered glass, and improve the test efficiency and data accuracy.

[0006] The technical implementation plan of the utility model is as follows: A tempered glass strength testing device includes a base, a tail rod, a front arm, an impact cone, a recovery column, and a clamping mechanism. A plurality of tail rods are connected to the upper side of the rear part of the base. The front arm is slidably connected between the upper parts of the tail rods. Impact cones are connected to the front sides of the left and right parts of the front arm. The bottoms of the impact cones are all telescopic structures. A recovery column is slidably connected to the base, and a clamping mechanism is arranged between the lower parts of the tail rods.

[0007] More preferably, handles are provided on both the left and right sides of the recovery column.

[0008] More preferably, the clamping mechanism includes an upper frame, a clamping spring, a lower frame, angle clamping plates and guide plates. The upper frame is slidably connected between the lower parts of the tail rods. The lower frame is slidably connected to the lower part of the upper frame. The tail rods are fixedly connected to the lower frame. A plurality of clamping springs are connected between the left and right parts of the upper frame and the lower frame. Angle clamping plates are connected to the left and right sides of the front parts of the upper frame and the lower frame. Guide plates are connected to the front sides of the angle clamping plates. Under the action of the tension of the clamping springs, the upper frame maintains a downward pressure to cooperate with the lower frame and the adjacent angle clamping plates, and can clamp the tempered glass to be tested.

[0009] More preferably, a protection mechanism is further included. The protection mechanism includes a protection frame, a cross plate, a buffer plate and a push rod. The protection frame is connected to the lower frame. Cross plates are connected to the lower sides of the left and right parts of the protection frame. A buffer plate is arranged between the tops of the cross plates. The push rod is slidably connected to the rear side of the protection frame. When the tempered glass is being tested, it is located inside the protection frame and is shielded and protected by the protection frame. The broken pieces of the tempered glass fall into the buffer plate, and the buffer plate buffers the pieces to prevent the pieces from falling and breaking and splashing again. By pushing the push rod forward, it is convenient to sweep and clean the pieces on the buffer plate.

[0010] More preferably, buffer springs are arranged between the front and rear parts of the cross plates and the buffer plate.

[0011] More preferably, a cleaning brush head is arranged on the front side of the push rod.

[0012] The beneficial effects of the present utility model are as follows: The present utility model is guided by the guide plates, so that the tempered glass is inserted between the upper frame and the lower frame.

Detailed implementation manners

[0019] The implementation manners of the present utility model will be described below with reference to the accompanying drawings.

[0020] A device for testing the strength of tempered glass, as Figures 1 - 3 shown, includes a base 1, a tail rod 2, a front arm 3, an impact cone 4, a recovery bar 5 and a clamping mechanism 6. A plurality of tail rods 2 are connected to the upper side of the rear part of the base 1. A front arm 3 is slidably connected between the upper parts of the tail rods 2. Impact cones 4 are connected to the front sides of the left and right parts of the front arm 3. The bottoms of the impact cones 4 are all telescopic structures. A recovery bar 5 is slidably connected to the base 1. A clamping mechanism 6 is provided between the lower parts of the tail rods 2.

[0021] As Figure 1 and Figure 4 shown, the clamping mechanism 6 includes an upper frame 61, a clamping spring 62, a lower frame 63, an angle splint 64 and a guide plate 65. An upper frame 61 is slidably connected between the lower parts of the tail rods 2. A lower frame 63 is slidably connected to the lower part of the upper frame 61. The tail rods 2 are all fixedly connected to the lower frame 63. A plurality of clamping springs 62 are connected between the left and right parts of the upper frame 61 and the lower frame 63. Angle splints 64 are connected to the left and right front sides of the front parts of the upper frame 61 and the lower frame 63. Guide plates 65 are connected to the front sides of the angle splints 64.

[0022] As Figure 1 and Figure 5 shown, it further includes a protection mechanism 7. The protection mechanism 7 includes a protection frame 71, a cross plate 72, a buffer plate 73 and a push rod 74. A protection frame 71 is connected to the lower frame 63. Cross plates 72 are connected to the lower sides of the left and right parts of the protection frame 71. A buffer plate 73 is provided between the tops of the cross plates 72. A push rod 74 is slidably connected to the rear side of the protection frame 71.

[0023] When the utility model is in use, first insert the tempered glass sample to be tested into the protection frame 71. At this time, it is guided by the guide plate 65 so that the tempered glass can be inserted between the upper frame 61 and the lower frame 63. Under the tension of the clamping spring 62, the upper frame 61 maintains a downward pressure and cooperates with the lower frame 63 and the adjacent angle clamping plate 64 to clamp the tested tempered glass. The tempered glass clamped by the tension of the clamping spring 62 can, when being impacted, squeeze the upper frame 61 and the lower frame 63 by its own structure, causing a certain deformation of the clamping spring 62, providing space for the energy absorption and release of the tempered glass, and preventing the tempered glass from bouncing out of the test area. Then, adjust the impact cone 4 from weak to strong to the impact force on the tempered glass until the tested tempered glass is broken. After being broken, replace the tempered glass sample and start testing from the impact force when the previous sample was broken. If it can be broken with one blow, it means that the limit of the explosion-proof performance of this type of tempered glass is the value set by the impact cone 4 at present. If it cannot be broken with one blow, continue to increase the impact force, and take the average value after multiple detections. The broken tempered glass fragments and the like will fall into the recycling bin 5. Due to the shielding protection of the protection frame 71, the broken tempered glass pieces fall into the buffer plate 73 to buffer the pieces and prevent the pieces from falling and breaking and splashing again. Push the push rod 74 forward to conveniently sweep and clean the pieces on the buffer plate 73.

The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
