Description

Technical Field

[0001] This application relates to the field of material combustion testing technology, and particularly to a flooring material combustion test device. Background Art

[0002] At present, flooring materials such as textiles, carpets, cork boards, wooden boards, rubber boards, plastic floors, and floor spraying materials need to undergo combustion tests before leaving the factory to evaluate their combustion performance. Such tests are usually carried out by means of a heat radiation source. By simulating the heat radiation conditions in the real environment, the combustion characteristics of the flooring materials are studied in depth. However, during the test, the radiation box needs to be tilted to multiple angles for experiments to more comprehensively evaluate the combustion performance of the materials.

[0003] When the existing flooring material combustion test device makes multi-angle adjustments, there are often problems with poor convenience in the operation process. The test personnel need to spend a lot of time and effort to adjust the angle of the radiation box, which not only affects the test efficiency but also may introduce errors due to improper operation. At the same time, the stability in the multi-angle adjustable state is also a major challenge faced by the existing device. When the radiation box is tilted to different angles, if it cannot be kept stable, it will lead to inaccurate test results or even test failures.

[0004] In view of the above related technologies, the inventor believes that the existing flooring material combustion test device has obvious deficiencies in terms of the convenience of angle adjustment and the stability in the multi-angle adjustable state, and urgent improvements are needed. Utility Model Content

[0005] In order to improve the convenience of angle adjustment and the stability in the multi-angle adjustable state of the existing flooring material combustion test device, this application provides a flooring material combustion test device.

[0006] The flooring material combustion test device provided by this application adopts the following technical solutions:

[0007] A flooring material combustion test device includes a mounting base. On the mounting base, a first mounting plate and a second mounting plate are symmetrically arranged. A radiation box is arranged between the first mounting plate and the second mounting plate. Rotating shafts are arranged on the end faces of the radiation box close to the first mounting plate and the second mounting plate. A rotating disk is arranged at one end of the rotating shaft close to the second mounting plate. Support rods are arranged at the four corners of the mounting base.

A locking component for locking the radiation box is arranged on the second mounting plate.

[0008] By adopting the above technical solution, when conducting a burning test on paving materials using the device, first adjust the angle of the radiation box according to the test requirements, then unlock the radiation box using the unlocking component, and then the operator adjusts it to the required angle using the driving component. Then, lock the radiation box again using the locking component to ensure that the radiation box can remain stable in a state where it can be adjusted at multiple angles. Subsequently, the burning test can be carried out, observing and recording the burning situation of the material.

At this time, the locking spring is in a compressed state. When the plug rod disengages from the plug slot, the operator can use the driving component to adjust the angle of the radiation box. After adjusting the angle, the operator releases the pressing plate, and the plug rod is inserted into the plug slot under the action of the locking spring, completing the locking of the radiation box again.

The driving motor drives the driving gear to rotate, and the driving gear drives the rotating shaft to rotate through the driven gear, thereby driving the radiation box to rotate. After the angle is adjusted, the operator locks the radiation box using the locking component, thereby completing the test requirements for multiple angles of the radiation box.

[0015] Preferably, a heat insulation layer is arranged on the inner side wall of the radiation box, and a temperature sensor for detecting the internal temperature is installed on the outer side wall of the radiation box.

[0016] By adopting the above technical solution, the setting of the heat insulation layer can reduce the heat loss in the radiation box and improve the test safety. At the same time, the temperature sensors on the outer side wall facilitate the operators to monitor the test temperature in real time. The settings of both enable the radiation box to have a heating function while maintaining good heat insulation effect and temperature monitoring accuracy.

[0017] Preferably, universal wheels are installed at the bottom of the legs, and pedals for foot brakes are installed on the universal wheels.

When using the device for the burning test of paving materials, first adjust the angle of the radiation box according to the test requirements, then unlock the radiation box by using the unlocking component, and then the operator adjusts it to the required angle by using the driving component. Then, lock the radiation box again by using the locking component to ensure that the radiation box can remain stable in a state of being adjustable at multiple angles. Subsequently, the burning test can be carried out, and the burning situation of the material can be observed and recorded. The setting of the legs provides good support for the mounting base and the radiation box;

[0025] 2. The operator pulls the pressing plate, and the movement of the pressing plate drives the insertion rod to move away from the second fixing plate. At this time, the locking spring is in a compressed state. When the insertion rod disengages from the insertion slot, the operator can adjust the angle of the radiation box by using the driving component. After adjusting the angle, the operator releases the pressing plate, and the insertion rod is inserted into the insertion slot under the action of the locking spring to complete the locking of the radiation box again;

[0026] 3. When the radiation box needs to be adjusted in angle, the operator starts the driving motor.
