Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire test instruments, in particular to an adjustable fire test bench. Background Technique
[0002] Fire testing can determine the ease of ignition or combustion of materials or finished products when a material or heat source is placed close to the center of the fire or the heat source. Its main test step is to place the sample to be tested inside the test bench, and by applying a heat source at an appropriate temperature, observe the fire resistance of the sample. It is a common test equipment.
[0003] The existing fire test benches have the following drawbacks when in use: The existing fire test benches are generally of a fixed structure, and the size of the internal test space cannot be adjusted. For smaller test samples, the combustion chamber space is too large, which is likely to cause waste of heat energy. For larger test samples, they cannot be directly placed inside the combustion chamber, and the use is not flexible enough. For this reason, we propose an adjustable fire test bench. Content of the Utility Model
[0004] The main purpose of the utility model is to provide an adjustable fire test bench. By setting an adjustment mechanism on one side of the machine body, by adjusting the distance between the insertion plate and the machine body, the internal volume space of the combustion chamber can be adjusted to adapt to test samples of different specifications, and the problems in the background technique can be effectively solved.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] An adjustable fire test bench includes a machine body and also includes an adjustment mechanism. The adjustment mechanism is arranged on one side of the machine body. The adjustment mechanism includes a fixed frame, an end plate, a slot, a flame-retardant sealing strip, an insertion plate, a support and a pulley. Fixed frames are fixedly connected to both the upper and lower ends inside the machine body, and end plates are installed through the fixed frames. A slot is opened between the end plate and the machine body. Flame-retardant sealing strips are adhesively bonded to both the outer wall of the end plate and the inner wall of the machine body facing the end plate. An insertion plate is inserted into the machine body through the slot. A support is installed at the bottom of the insertion plate away from the machine body, and a pulley is installed at the bottom of the support.
[0007] Further, it further includes an auxiliary mechanism. The auxiliary mechanism is provided at the bottom of the plug board. The auxiliary mechanism includes a bottom plate, a hinge, a movable plate, and mounting holes. The bottom of the plug board is fixedly connected to the bottom plate. The movable plate is embedded in the bottom of the bottom plate, and one side of the bottom of the bottom plate is connected to the movable plate through a hinge. Mounting holes are provided at the tops of both the bottom plate and the movable plate. At the bottom of the plug board, there is a structure of the bottom plate and the movable plate. In the normal use state, the movable plate is closed, and its top is flush with the surface of the bottom plate. Mounting holes are provided at the tops of both the bottom plate and the movable plate. Through the mounting hole structure, it is convenient to install a support component to fixedly install the sample to be tested. After the fire test is completed, some of the burned-out substances generated during the test process will fall onto the surface of the bottom plate. At this time, the movable plate can be opened along the hinge to clean the burned-out substances on the surface of the bottom plate.
[0008] Further, a burner is installed on the surface of the machine body away from the plug board. A combustion tube extending to the side of the plug board on the surface of the end plate is provided on the surface of the burner; when the burner operates, heat source is provided to the inside of the combustion chamber through the combustion tube.
[0009] Further, a viewing window for observing the situation of the combustion chamber is embedded on one side of the surface of the plug board; through the viewing window structure, it is convenient to observe the combustion situation inside the combustion chamber.
[0010] Further, a lock seat is fixedly connected to one side of the bottom of the bottom plate close to the end of the movable plate. A lock pin inserted into the inside of the lock seat is installed on one side of the bottom of the movable plate; in the test state, the lock pin is inserted into the inside of the lock seat to fix the angle of the movable plate. When cleaning is required, the lock pin can be pulled out to open the movable plate.
[0011] Compared with the prior art, the utility model has the following beneficial effects: Inside the machine body, an end plate structure is connected through a fixing frame. Slots are provided on the outer periphery of the end plate, and a plug board is inserted through the slots. The space between the inside of the plug board and the end plate is the combustion chamber space. The support and pulley play a supporting role for the plug board. Before the fire test, the plug board is horizontally pulled along the slot to adjust the space between the inside of the plug board and the end plate. When testing small samples, the combustion chamber space is reduced to reduce heat energy waste. When testing large samples, the combustion chamber space is enlarged to facilitate the placement of samples. During the process of pulling the plug board, the flame retardant sealing strip ensures the sealing performance of the connection and reduces the influence of heat on the inside of the machine body. The movable and adjustable structure can quickly adjust the combustion chamber space to meet the test requirements of different specifications of samples; at the bottom of the plug board, there is a structure of the bottom plate and the movable plate. In the normal use state, the movable plate is closed, and its top is flush with the surface of the bottom plate. Mounting holes are provided at the tops of both the bottom plate and the movable plate. Through the mounting hole structure, it is convenient to install a support component to fixedly install the sample to be tested. After the fire test is completed, some of the burned-out substances generated during the test process will fall onto the surface of the bottom plate. At this time, the movable plate can be opened along the hinge to clean the burned-out substances on the surface of the bottom plate. Description of the Drawings
