DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] like Figure 1 , 2 As shown in Figure 3, a device for testing the multiple bending performance of waterproof materials includes a device frame 1, and is characterized in that: a rotating shaft 3 driven by a motor 2 is installed on the device frame, and a plurality of turntables 4 evenly distributed from left to right are installed on the rotating shaft, and a connecting rod 5 is connected under the turntable, and a clamping piece 6 for clamping the waterproof material is provided under the connecting rod, and the clamping piece is a component for clamping the waterproof material 7. When the motor drives the rotating shaft to rotate, the clamping piece moves up and down, so that the waterproof material clamped in the clamping piece is continuously bent.
[0019] For example, the rotating shaft may use a crankshaft, just like the crankshaft on a multi-cylinder engine in the prior art, so that when the motor drives the rotating shaft to rotate, the clamping member moves up and down, causing the waterproof material clamped in the clamping member to bend continuously.
[0020] Alternatively, the turntable may include a first turntable 41 and a second turntable 42 connected laterally, as shown in the figure. In the process of the motor driving the shaft to rotate, the clamping member may move up and down, so that the waterproof material clamped in the clamping member is continuously bent.
[0021] The utility model is configured such that different parts of the waterproof material are sequentially mounted on the clamp along the length direction, the motor is started, the shaft rotates, the waterproof material in the clamp is continuously bent, the waterproof material is removed after a period of time, and whether the waterproof material is leaking is detected. The flexibility of the waterproof material can be detected, thereby achieving the purpose of the utility model.
[0022] Furthermore, during the rotation of the shaft, the connecting line of the plurality of clamps is on a sine curve.
[0023] In a certain state, the positions of the connecting rods on the turntable are different, and the positions of adjacent connecting rods on the turntable are progressive around the turntable in sequence, which can ensure that during the rotation of the shaft, the connecting line of multiple clamps is on a sine curve.
[0024] Furthermore, the clamping member comprises an upper clamping rod 61 and a lower clamping rod 62, and a placement station for placing waterproof materials is located between the upper clamping rod and the lower clamping rod.
[0025] Furthermore, the device frame has a small chamber 8, in front of which is a small chamber door 81, and the card is in the small chamber. The device also includes a temperature-changing component 9, which is a heating device and / or a cooling device, and the temperature-changing component can change the temperature in the small chamber.
[0026] For example, the temperature-changing component is a refrigerator or a heating tube, an air conditioner or a water heater, as long as it can change the temperature in the small room.
[0027] The utility model is arranged in this way, and can also measure the multiple bending performances of the waterproof material at different temperatures, which is more convenient to use.
[0028] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
