BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 is the general assembly structure schematic view of the fireproof film fire resistance testing device. DETAILED DESCRIPTION

[0013] The specific embodiment of the utility model will be further described in combination with the accompanying drawings, so that the technical scheme of the utility model is easier to understand and grasp, and the protection scope of the utility model is more clearly defined.

[0014] The utility model innovatively proposes a fireproof film fire resistance testing device, so as to solve the problem of high simulation and safety protection.

[0015] The utility model discloses a fireproof film fire resistance testing device mainly by base 1, clamping part 2 and the three parts of fire collector injector 3 constitute. In which clamping part 2 is equipped with vertical frame 21 and clamp 22, vertical frame 21 is fixedly connected on the surface one side of base 1, is mainly used for lifting clamp 22 and makes it empty a certain height, makes high temperature burning occur in the air, delays the speed of heat energy transmission to base. The clamp 22 is composed of two annular chuck through the middle part, fills and locks and fixes the fireproof film of waiting for measuring in the clamp. Fire collector injector 3 is slidably assembled on base 1 and the adjustable distance far and near of the positive side chuck 22a of clamp. From the preferred implementation, the positive side chuck 22a can be integrally formed with vertical frame 21 by sheet metal or metal punching process.

[0016] In the preferred embodiment, the base 1 is provided with a complete set of slide rails 4 and slide tables 5, and the slide table 5 is provided with a container groove 51 corresponding to the liquid tank of the fire collector injector 3.

[0017] The fire resistance testing device has simple structure and low cost, which is beneficial for product research and development test, finished product quality inspection and new energy vehicle enterprise product acceptance of the vehicle film manufacturer. During the fire resistance test, the fireproof film to be tested is first cut and sampled, and then lowered and clamped in the clamp and locked and clamped by screws, so that the fireproof film is exposed before and after the hollow part in the middle of the annular chuck. The fire collector injector is ignited and sprayed with sufficient liquid, and then placed in the container groove for clamping. Adjust the position of the slide table to make the flame port of the fire collector injector close to the clamping part, and then position until the distance between the fireproof film to be tested reaches the test requirement, and then observe and count the width and time of the fireproof film being burned through. As can be seen, during the test operation, there is no need for manual holding of the fireproof film to be tested or the clamp, and the distance between the flame port of the fire collector injector and the fireproof film can be kept stable, and the burning point is concentrated. This can better simulate the destructive damage caused by the fire or electric arc of battery explosion.

[0018] To increase the convenience of the above test operation, the surface of the base 1 is provided with a positioning scale 6 parallel to the slide rails to provide a reference for positioning of the slide block. At the same time, a manual trigger type timer 7 can also be optionally provided on the base 1, which is shown as a digital tube display. The touch keys of the timer are set as one press to start timing, two presses to pause timing, double-click to clear, and long press for three seconds to turn off and standby. Of course, the timer can also be set as a dial display, etc.

[0019] In view of the requirement that the high temperature resistance performance of the fireproof film during the research and development process needs to exceed the metal plate (such as aluminum plate) constituting the vehicle frame. And the fireproof film is often directly attached to the surface of the vehicle frame chassis during actual production and use. Therefore, during the fire resistance test, the fireproof film can be clamped alone for burning; or the fireproof film and the battery box or the aluminum plate of the vehicle frame can be clamped together, and the aluminum plate is closer to the injection port of the fire collector injector. In this way, it can be more intuitively measured whether the protective film is still complete when the aluminum plate is burned through, and it can be based on this to curb the spread of the fire for a longer time.

[0020] As can be seen from the above description of the scheme and the embodiment of the fireproof film fire resistance testing device of the present application, the scheme has substantial features and progress: the device provides a mounting carrier for positioning the cut sample of the fireproof film in the air, improves the spatial positioning stability of the fireproof film when being burned by the jet flame, and also reduces the potential harmfulness of the jet flame to the surrounding fire; the device has a simple structure and is convenient for quickly carrying out testing operations in multiple scenes to verify the fireproof quality of the product.

[0021] In addition to the above embodiments, the present application can also have other implementation manners, and any technical scheme formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
