Description

Technical Field

[0001] This invention relates to the field of fire resistance performance testing technology for building materials, specifically a portable multifunctional integrated combustion tester. Background Technology

[0002] Flammability testing of building materials is mainly used to determine the ignition performance, combustion spread, and dripping characteristics of building materials under small flame conditions. Flammability testing can scientifically determine the ease with which materials are ignited, their flame spread characteristics, and combustion hazards. This provides a reliable basis for fire protection classification of building materials, material selection in engineering design, and fire safety acceptance and supervision, reducing fire hazards at the source, delaying fire spread, and extending evacuation and rescue time. Vertical burning testing of textiles is a key technical means to assess the fire safety performance of textile materials. Textiles, as commonly used materials in clothing, home decoration, and other fields, are widely present in people's production and daily life. Once exposed to an open flame, they are easily ignited, burn rapidly, and easily produce molten drips and toxic fumes, which can easily cause fire spread, burns, and suffocation. Vertical burning testing of textiles can scientifically determine the ignition time, afterflame time, smoldering time, damage length, and dripping characteristics of fabrics, providing a basis for the classification of textile flame retardant performance, product quality control, standard implementation, and material selection in engineering projects.

[0003] Currently, the existing equipment mainly falls into the following categories:

[0004] 1. The laboratory flammability tester is designed in strict accordance with relevant standards such as GB / T8626. The main body of the equipment adopts a flame-retardant box structure and is equipped with a precise adjustable standard burner and an automatic ignition and timing control system, which can stably control the flame height, ignition angle and action time. 2. Small flammability testing device, which adopts a base-fixed igniter and sample clamping structure, uses butane flame as ignition source, and tests the flammability of materials by flame impact at a fixed position. It is small in size and can realize rapid on-site screening. 3. Handheld portable combustible ignition device, using a common butane spray gun with a simple ruler, manually controls the ignition distance and time, and makes a preliminary judgment by visually observing the combustion situation. It is low in cost but poor in accuracy. 4. Laboratory textile vertical testing equipment: The instrument consists of a flame-retardant testing chamber, a standard ignition burner, a sample clamping device, and an automatic ignition and timing control system. It can precisely control the flame height, ignition time, and combustion angle, and automatically record afterflame and smoldering times. The equipment is bulky and heavy, requiring fixed installation in a laboratory environment, and is equipped with dedicated gas pipelines and a ventilation system. 5. Portable textile vertical combustion detection device adopts a split structure, with the igniter, bracket and gas cylinder as independent components. It needs to be temporarily assembled when used on site. The igniter position is fixed. The gas cylinder is mostly a civilian liquefied gas cylinder or a large-capacity industrial gas cylinder.

[0005] However, standard laboratory testing equipment is bulky, heavy, and cannot be deployed on-site. It has a long testing cycle, high cost, and cannot meet the needs of real-time sampling inspection of incoming materials. Unqualified materials are prone to enter the construction site. Small flammability testing devices have fixed ignition positions, making it impossible to adjust the flame impact angle and distance. The size, shape, and type of the sample are limited. The parameter control of handheld ignition testing methods depends entirely on manual operation, resulting in poor accuracy. Portable textile vertical combustion testing devices often have fixed igniter positions or can only be manually adjusted in height, making it impossible to achieve precise displacement control in the front and back directions. Gas cylinders are mostly civilian liquefied gas cylinders or large-capacity industrial gas cylinders, which are inconvenient to carry and pose safety hazards. Summary of the Invention

[0016] Preferably, one end of the movable rod is fixed with a clip, and the clip is engaged with the outside of another hanging plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This portable multi-functional integrated combustion tester features a portable multi-functional support frame and gas supply device design, making it small in size and lightweight. It is designed with a guide rail sliding ignition mechanism, which can adjust the ignition distance and position. It uses an adjustable sample clamp to hold samples of different sizes and fixes a small butane gas cylinder inside the support cylinder, avoiding the safety hazards caused by external gas cylinders and improving the portability and safety of the device.

[0018] 2. This portable multi-functional integrated combustion tester can achieve the purpose of adjusting the spacing. The spacing between the two abutment rings is adjustable.

The clamp can be used to limit the corresponding hanging plate. Since the two hanging plates are connected and fixed together by the limit frame, the two hanging plates are limited as a whole, preventing the two hanging plates from shaking back and forth during use.

[0020] 4. This portable multi-functional integrated combustion tester can achieve the purpose of quick clamping and fixing. After placing the two sides of the material on the front of the two hanging plates respectively, manually push the push block upward, the moving frame moves upward, all the blocks on it move upward, the moving plate, connecting rod and clamping plate automatically pop open and clamp the material, which can achieve a quick and firm clamping effect.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 8 This invention provides a technical solution: a portable multifunctional integrated combustion tester, including a base 1, a support cylinder 2 and a slide rail 10 fixed on one side of the upper surface of the base 1, a gas cylinder 3 placed inside the support cylinder 2, a valve 4 fixed on the top of the gas cylinder 3, the top of the valve 4 connected to an igniter 6 via a connecting pipe 5, a tray 9 fixed on the other side of the upper surface of the base 1, two first sliders 12 slidably connected inside the slide rail 10, a movable plate 11 fixed between the two first sliders 12, a clamping mechanism 14 fixed at the bottom of the movable plate 11, the clamping mechanism 14 including a bracket 1401, two hanging plates 1404 hanging on the bracket 1401, first springs 1409 fixed at equal intervals on the rear side of the hanging plates 1404, a movable plate 1410 fixed at the rear end of the first springs 1409, the front side of the movable plate 1410 connected to a clamping piece 1412 via a connecting rod 1411, the connecting rod 1411 penetrating through the hanging plate 1404.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, a fixing sleeve 7 is fixed to the outside of the igniter 6, and a support block 8 is fixed to the other side of the upper surface of the base 1. The fixing sleeve 7 passes through the support block 8. When the igniter 6 is manually pushed and pulled back and forth for positioning, the fixing sleeve 7 slides on the support block 8, which facilitates the support and limiting of the igniter 6.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, both first sliders 12 are fixed to the slide rail 10 by first fasteners 13. The two first sliders 12 can slide up and down in the slide rail 10 to facilitate the adjustment of the height of the bracket 1401 and the two hanging plates 1404. After the height adjustment operation is completed, the two first fasteners 13 can be tightened to secure the two first sliders 12.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, two abutment rings 1402 are slidably connected to the outer side of the bracket 1401, and both abutment rings 1402 are fixed to the bracket 1401 by the second fastener 1403. The hanging plate 1404 can be removed from the bracket 1401. The distance between the two abutment rings 1402 is adjustable. The hanging plate 1404 abuts against the inner side of the abutment rings 1402. The distance between the two hanging plates 1404 can be adjusted by adjusting the distance between the two abutment rings 1402. The distance between the two hanging plates 1404 can be adjusted according to the size of the material. After the distance adjustment operation is completed, the second fastener 1403 can be tightened to secure the abutment rings 1402.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a limiting frame 1405 is fixed to the front side of one of the hanging plates 1404, and a limiting block 1406 is fixed to the front side of the other hanging plate 1404. The limiting block 1406 is slidably connected to the inner side of the limiting frame 1405. During the process of opening and closing the two hanging plates 1404, the limiting block 1406 slides within the limiting frame 1405, thus facilitating the limiting function.

[0029] In this embodiment, as Figure 1 and Figure 5 As shown, a backing plate 1407 is placed on the outside of the limiting frame 1405, and the backing plate 1407 is fixed to the front of the limiting block 1406 by bolts 1408. After the two hanging plates 1404 are unfolded, the backing plate 1407 can be fixed to the limiting block 1406 by bolts 1408. The backing plate 1407 plays a role in pressing and fixing the limiting frame 1405, and the two hanging plates 1404 are connected and fixed together through the limiting frame 1405.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 7 As shown, a protrusion 1413 is fixed to the rear side of the mounting plate 1404, and the top of the protrusion 1413 is connected to the movable frame 1415 through the second spring 1414. Two limiting sleeves 1416 are fixed to the rear side of the mounting plate 1404, and the movable frame 1415 passes through the two limiting sleeves 1416. A push block 1417 is fixed to the bottom of the movable frame 1415. When the push block 1417 is pushed upward manually, the movable frame 1415 moves upward accordingly. The two limiting sleeves 1416 limit the movable frame 1415.

[0031] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, locking mechanisms 1418 are fixed at equal intervals on the rear side of the movable frame 1415. Each locking mechanism 1418 includes a first sleeve 14181, a third spring 14182 fixed to the inner top of the first sleeve 14181, and a stop block 14183 fixed to the bottom of the third spring 14182. The stop block 14183 penetrates the bottom of the first sleeve 14181, and the stop block 14183 corresponds one-to-one with the movable plate 1410. Initially, the stop block 14183 blocks the movable plate 1410. After placing the material between the hanging plate 1404 and the clamping piece 1412, manually push the moving frame 1415 upward. All the stops 14183 move upward, and the movable plate 1410 is not blocked by the stops 14183. The movable plate 1410, the connecting rod 1411 and the clamping piece 1412 automatically spring open under the action of the third spring 14182. The clamping piece 1412 can automatically press down the material, and the clamping pieces 1412 on the two hanging plates 1404 can clamp the two sides of the material respectively.

[0032] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a second slider 15 is slidably connected inside the slide rail 10, and a second sleeve 16 is fixed to the bottom of the second slider 15. The second slider 15 is fixed to the slide rail 10 by a third fastener 17. A movable rod 18 is slidably connected inside the second sleeve 16, and the movable rod 18 and the second sleeve 16 form a telescopic structure. The movable rod 18 is fixed to the second sleeve 16 by a fourth fastener 19. The second slider 15 can slide up and down inside the slide rail 10. Tightening the third fastener 17 can abut and fix the second slider 15. The movable rod 18 can extend and retract inside the second sleeve 16. Tightening the fourth fastener 19 can abut and fix the movable rod 18.

[0033] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, one end of the movable rod 18 is fixed with a clip 20, and the clip 20 is engaged with the outside of another hanging plate 1404. The height of the clip 20 can be adjusted by adjusting the height of the second slider 15. The height of the clip 20 is adjusted according to the height of the hanging plate 1404. After adjusting the height of the clip 20 and locking the second slider 15, the movable rod 18 can be pulled to lock the clip 20 on the outside of the corresponding hanging plate 1404, which helps to stabilize the two hanging plates 1404 and prevent the hanging plates 1404 from swaying back and forth.

[0034] The method of use and advantages of this invention: The working process of this portable multifunctional integrated combustion tester is as follows: like Figures 1 to 8As shown: First, select the corresponding size of the hanging plate 1404 according to the material size. Before hanging the two hanging plates 1404 on the bracket 1401, the distance between the two abutment rings 1402 can be adjusted. After completing the distance adjustment, use the second fastener 1403 to lock the abutment rings 1402. When hanging the two hanging plates 1404 on the bracket 1401, the hanging plates 1404 need to be pressed against the inside of the abutment rings 1402. At this time, the limiting block 1406 slides inside the limiting frame 1405. After hanging the two hanging plates 1404, use the bolt 1408 to fix the abutment plate 1407 to the limiting block 1402. On the front side of 06, the abutment plate 1407 presses against and fixes the limiting frame 1405. The two hanging plates 1404 are connected and fixed together through the limiting frame 1405. Then, the height of the two hanging plates 1404 is adjusted by sliding the two first sliders 12. Tightening the first fastener 13 can lock the first slider 12. Then, the height of the clamp 20 is adjusted by sliding the second slider 15 so that the clamp 20 is slightly higher than the bottom of the hanging plate 1404. Tightening the third fastener 17 can lock the second slider 15. Then, the movable rod 18 is pulled to lock the clamp 20 onto the corresponding hanging plate 1404, thereby limiting the two hanging plates 1404. Hanging plate 1404 is used to prevent the two hanging plates 1404 from wobbling back and forth. Tightening the fourth fastener 19 locks the movable rod 18. After placing one side of the material between one of the hanging plates 1404 and the clamping piece 1412, push the push block 1417 upwards manually. The corresponding movable frame 1415 moves upwards, and all the stops 14183 on it move upwards. The movable plate 1410 is unlocked and automatically pops open. The connecting rod 1411 and the clamping piece 1412 move backwards and press down on the material. After releasing the push block 1417, the movable frame 1415 automatically pops down, and the stops 14183 are in front of the movable plate 1410. Then, repeat the above clamping operation to clamp and fix the other side of the material to another hanging plate 1404. Then, use the igniter 6 to ignite and burn the material. The molten material will drip into the tray 9. The gas cylinder 3 stores combustible gas. The opening and closing of the valve 4 and the degree of opening can be controlled by rotating the knob on the valve 4, thereby controlling the gas flow. The igniter 6 can move back and forth to facilitate adjustment of the ignition distance and position. After using the device, press the movable plate 1410 directly. After the movable plate 1410 passes the stop block 14183, the stop block 14183 automatically pops down and blocks the movable plate 1410 again.
