[0002] The horizontal-vertical flame test is a method used to determine the combustion performance of plastics, rubber, films, and other materials under a specified fire source. It is primarily used to determine their fire resistance rating. This test is primarily applicable to electrical and electronic products and their components.

[0003] During the test, the specimen is fixed in a test chamber. Flame is applied to the specimen for a specified period of time, then removed, and the afterflame and smoldering times are recorded. The combustion characteristics of the specimen can be assessed by measuring parameters such as the linear burning rate, afterflame and afterglow time, and the extent of combustion and dripping of flame particles.

[0004] During the test, the sample to be tested is generally fixed by a clamping device. However, the clamping device inside the current tester has a simple structure and can only fix one sample to be tested. In order to increase the accuracy of the test, multiple samples are generally tested. As a result, after the test of one sample to be tested is completed, there is no need to open the door of the tester to disassemble it and re-fix another row of samples to be tested, which greatly reduces the test efficiency.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a portable horizontal and vertical combustion tester, comprising a crossbar 1 and a plurality of sliders 2. A slide groove is provided on one side surface of the crossbar 1, and the plurality of sliders 2 are slidably arranged in the slide groove. The sliders 2 are all arranged to abut against each other. A cylinder 11 for pushing the sliders 2 to move is installed at one end of the crossbar 1. One side of the slider 2 protrudes to form a fixing portion 3. The fixing portion 3 is provided with a clamping groove 4 and a fixing groove. A baffle 7 is provided in the fixing groove, and a clamping plate 5 is provided in the clamping groove 4.

[0023] Among them, thermal insulation layers are installed on both sides of the baffle, and the thermal insulation layers are made of thermal insulation materials. The thermal insulation effect is increased by the baffle and the thermal insulation layer.

[0024] In this embodiment, bearings are embedded on one side of the clamping plate 5, and screw holes are provided on one side of the fixing portion 3 facing the inner ring of the bearing. Screws are threadedly connected in the screw holes, one end of the screw is installed in the inner ring of the bearing, and a handwheel 6 is installed on the other end.

[0025] In this embodiment, a groove is provided at the end of the slide away from the cylinder 11, and the groove is provided at the bottom of the slide. A limit strip is adhered and fixed in the groove. A part of the limit strip protrudes out of the groove and contacts the leftmost slider 2. The rightmost slider 2 contacts the piston rod of the cylinder 11.

[0026] In this embodiment, the limiting strip is made of rubber material, and both sides of the rubber strip 9 form arc-shaped guide portions, so that the slider can pass through the limiting sleeve smoothly.

[0027] In this embodiment, the top of the baffle 7 is bent to form a connecting portion 8, and the connecting portion 8 is placed on the fixing portion 3. The connecting portion 8 is fixed to the fixing portion 3 by a hand-tightening bolt. The baffle can be fixed through the connecting portion, and after the hand-tightening bolt is removed, the baffle can be taken out along the fixing groove, which is convenient for its replacement.

[0028] In this embodiment, the cross-sections of the slide groove and the slider 2 are both arranged in a "T"-shaped structure, so that the slider can only move back and forth along the slide groove, thereby ensuring the stability of the slider.

[0029] In this embodiment, a fixing seat 10 is installed on the top surface of the crossbar 1. The fixing seat 10 is provided with a straight slot, and a bolt can pass through the straight slot to fix the crossbar inside the tester.

[0030] When in use, the slider can be removed from the crossbar along the slide groove, so that the slider can move to the outside. At this time, one end of the sample to be tested can be placed in the clamping groove, and the screw is rotated by the handwheel to move the screw along the screw hole toward the clamping groove. The movement of the screw drives the clamping plate, and the clamping plate can clamp and fix the sample to be tested by closing it. After multiple samples to be tested are clamped and fixed in the slider, multiple sliders can be slid into the slide groove;

[0031] During the insertion of the slider, the slider can squeeze the limit strip so that the limit strip is pressed into the groove, thereby not affecting the passage of the slider, but having a certain resistance when passing through, thereby increasing the limiting effect;

[0032] After multiple sliders are set between the cylinder and the limit bar, the flame inside the tester can first burn the leftmost test sample. The baffle can block the flame to avoid affecting the adjacent test samples. After the test of the leftmost test sample is completed, the cylinder can be started to extend the cylinder piston rod. The piston rod can push the slider to push the leftmost slider together with the test sample out of the slide slot, and the adjacent slider can be moved to the bottom of the flame and subjected to combustion test, which greatly increases the test efficiency and eliminates the need for repeated opening and closing of the door.

[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
