Description

Technical Field

[0001] This utility model relates to the field of flame retardant testing technology, and in particular to a flame retardant testing device. Background Technology

[0002] Flame retardancy testing is a test to evaluate the flame retardant properties of materials or products under combustion conditions. It is mainly used to assess their ability to delay flame spread and reduce the risk of combustion.

[0003] When flame retardant testing devices are used to conduct flame retardant tests on wood, the wood will carbonize after burning to a certain extent, causing the waste residue produced by the wood combustion to fall into the testing device. The long-term accumulation of waste residue increases the cost of manual cleaning, and the high temperature of the waste residue makes it easy to accidentally touch and burn the wood during manual cleaning. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flame-retardant testing device.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0025] Reference Figures 1-5 A flame retardant testing device includes a housing 4 with a support frame 3 fixed at the bottom. The top of the housing 4 is provided with a clamping assembly, which includes two U-shaped blocks 10. The U-shaped blocks 10 are fixed to the inner wall of the top of the housing 4 by bolts. A screw rod 12 is threaded to one side of the two U-shaped blocks 10. A pressure block 11 is rotatably connected to one end of the screw rod 12 and is located inside the U-shaped blocks 10. The wood to be tested is placed vertically between the two U-shaped blocks 10. At this time, the top of the wood is located inside the two U-shaped blocks 10 and in contact with a vertical plate on the U-shaped blocks 10. Then, the screw rod 12 is rotated so that the pressure block 11 presses and contacts the wood, thereby positioning and clamping the wood.

[0026] A discharge port is provided at the bottom of one side of the housing 4. A baffle plate 20 is rotatably connected inside the discharge port. A movable flame-spraying assembly is provided inside the housing 4. The flame-spraying assembly includes a support plate, which is fixed to the outer wall of one side of the housing 4 by bolts. An electric push rod 5 is fixed to the support plate by bolts. A slide 18 is fixed to the inner wall of one side of the housing 4 by bolts. A slider 14 is slidably connected to the slide 18. A flame-spraying head 13 is fixed to the top of the slider 14 by bolts. During the test, the use of the slide 18 and the slider 14 makes it easy for the staff to adjust the flame-spraying position of the flame-spraying head 13. The flame-spraying pipe of the flame-spraying head 13 passes through the housing 4 and can move along the housing 4. The electric push rod 5 extends to move the slider 14 along the slide 18 until the flame-spraying head 13 is moved to the position where it needs to be flame-sprayed. Since the flame-spraying head 13 is connected to an external ignition device through the flame-spraying pipe, the flame-spraying head 13 ignites the wood through the external ignition device to start the flame-retardant test. During the test, the waste from the burning wood falls to the bottom of the housing 4.

[0027] Specifically, a fixing frame 6 is movably inserted into one side of the housing 4. The fixing frame 6 passes through the housing 4 and is fixed with a scraper 15 by bolts. The scraper 15 is in contact with the bottom inner wall of the housing 4. A fixing post 19 is fixed to the top of the scraper 15 by bolts. The fixing post 19 can contact the baffle plate 20. A moving rod 8 is movably inserted into one side of the housing 4 and is fixed to the fixing frame 6. One end of the moving rod 8 that passes through the housing 4 is fixed to the scraper 15. A return spring 9 is sleeved on the outside of the moving rod 8, and the two ends of the return spring 9 are respectively fixed to the fixing frame 6 and the housing 4. With the body 4 fixed in place, the worker pushes the moving rod 8, causing the fixed frame 6 to move the scraper 15 and the fixed column 19, and the return spring 9 contracts. At this time, the scraper 15 cleans the waste at the bottom of the housing 4. Then the fixed frame 6 continues to move so that the fixed column 19 first contacts the baffle 20 and pushes the baffle 20 to rotate and open. The two sides of the support frame 3 are fixed with collection boxes 2 by bolts, and the two collection boxes 2 are located at the bottom of the two sides of the housing 4 respectively. Then the scraper 15 drops the cleaned waste into the collection box 2 through the discharge port, thus cleaning the waste.

[0028] It should be noted that one end of the slide 18 is fixed with a limit plate 16 by bolts. The limit plate 16 can limit the distance of movement of the slider 14. Two second guide rods 17 are fixed to one side of the limit plate 16 by bolts, and the second guide rods 17 are fixed to the housing 4. The slider 14 is slidably connected to the second guide rods 17. The second guide rods 17 can guide the slider 14 and prevent the slider 14 from tilting during movement. Two first guide rods 7 are fixed to one side of the outer wall of the housing 4 by bolts, and the fixing frame 6 is slidably connected to the first guide rods 7. The first guide rods 7 can guide the fixing frame 6. An installation port is opened on one side of the housing 4. A shielding door 1 is rotatably connected in the installation port. The shielding door 1 allows the staff to understand the working conditions inside the housing 4. The shielding door 1 is fixed to the housing 4 by a latch. When the shielding door 1 is closed, it is secured to the housing 4 by the latch for flame retardant testing. The shielding door 1 is composed of borosilicate glass and a mounting frame made of magnesium oxide board, which gives it a flame retardant effect and prevents the flame retardant test from affecting the outside, thus providing a protective effect.

[0029] Working principle: The wood to be tested is placed vertically between two U-shaped blocks 10. At this time, the top of the wood is located inside the two U-shaped blocks 10 and in contact with a vertical plate on the U-shaped block 10. Then, the screw 12 is rotated, causing the pressure block 11 to press and contact the wood, positioning and clamping it. Then, the electric push rod 5 is activated, extending the electric push rod 5 to move the slider 14 along the slide 18 until the flame head 13 is moved to the position where flame is needed. Since the flame head 13 is connected to an external ignition device through a flame pipe, the external ignition device ignites the wood. The flame head 13 ignites the wood to begin the flame retardant test. During the test, the waste from the burning wood falls to the bottom of the housing 4. Then, the staff pushes the moving rod 8, which causes the fixed frame 6 to move the scraper 15 and the fixed column 19. The scraper 15 cleans up the waste at the bottom of the housing 4, and the return spring 9 contracts. Then, the fixed frame 6 continues to move, causing the fixed column 19 to contact the baffle 20 first, and push the baffle 20 to rotate and open. Immediately afterwards, the scraper 15 drops the cleaned waste into the collection box 2 through the discharge port, thus cleaning up the waste.
