Description

Technical Field

[0001] This utility model relates to a combustion testing device for flame-retardant glass fiber cloth, belonging to the technical field of fabric performance testing equipment. Background Technology

[0002] Flame-retardant fiberglass mesh is used in many industrial and civil buildings. This mesh is made by coating a fiberglass mesh blank with flame-retardant positioning adhesive and then drying it. The flame retardancy of the flame-retardant fiberglass mesh requires testing equipment. Our company uses a textile vertical flammability tester. During the test, the vertical sample is ignited several times at a certain flame height and a certain flame angle. The flammability is evaluated by the duration of ignition and burning of the sample and whether the igniter material laid under the sample is ignited.

[0003] The clamping assembly structure used in this device involves clamping the test fabric between two sets of fork plates, and then fixing it by clamping the two sets of fork plates with multiple sets of movable clamps, which is relatively inconvenient when clamping.

[0004] To address this issue, our company discovered during a search that application number 2023224489160 discloses a horizontal and vertical flammability tester. This tester includes a test chamber with a fixing fixture inside the chamber above the ignition mechanism. The fixing fixture includes a bottom fork plate, a cover fork plate, and a suspension component. The bottom fork plate is slidably connected to the top of the test chamber via the suspension component, and the cover fork plate is slidably engaged with the surface of the bottom fork plate. The test sample is laid flat on the surface of the bottom fork plate, located between the cover fork plate and the bottom fork plate. In this invention, the bottom fork plate and the cover fork plate are slidably engaged. During use, the test sample needs to be clamped between the bottom fork plate and the cover fork plate for secure fixation. However, the sliding assembly of the cover fork plate can lift the test sample, causing it to wrinkle, affecting the combustion time, and resulting in distorted combustion quality test results. Summary of the Invention

[0005] The purpose of this invention is to provide a combustion testing device for flame-retardant fiberglass cloth to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A combustion testing device for flame-retardant fiberglass cloth includes a test chamber. A test instrument host is provided on one side of the test chamber. The test instrument host is connected to an ignition mechanism fixedly installed inside the test chamber through a connection control mechanism and controls the opening and closing of the ignition mechanism. A clamping assembly is provided above the ignition mechanism. The clamping assembly is suspended on a suspension assembly, which is placed on the top plate inside the test chamber.

[0008] The clamping assembly includes a support body, which includes a vertical plate and a top horizontal plate. The vertical plate has a combustion zone, and a recessed area is provided around the combustion zone. A pair of symmetrically arranged pressure plates are rotatably disposed in the recessed area via a rotating shaft. The lower surface of the pressure plates and the upper surface of the recessed area are respectively provided with multiple sets of mating magnets, which are used to clamp the test sample.

[0009] A suspension tube is welded to the top of the horizontal plate, and the suspension tube is connected to the suspension assembly.

[0010] Furthermore, the suspension assembly includes a mounting plate and a suspension rod. The mounting plate is fixedly connected to the top plate inside the test chamber. The top of the suspension rod is connected to the mounting plate. The suspension rod has an L-shaped structure, and the bottom of the suspension rod is a suspension crossbar. A state-holding block is provided on the surface of the suspension crossbar to keep the vertical plate in a vertical state. The axis of the suspension tube has a central hole, and the central hole has a state-holding hole corresponding to the state-holding block.
