Description

Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and in particular to a wall covering flame retardant detection device. Background Technology

[0002] Wall coverings, also known as "wall fabrics," are fabrics used to cover walls. They are made with cotton cloth as the base, and printed or embossed designs are applied to the base. Some are also made with large jacquard weaves, and the patterns used are mostly geometric and floral. There are also wall coverings made using embroidery techniques.

[0003] For example, CN221572454U discloses a wallcovering flame retardant testing device to solve the technical problem mentioned in the background art: existing wallcovering flame retardant testing devices place the wallcovering on a feeding roller and a receiving roller. During flame retardant testing, the wallcovering surface has certain wrinkles due to its own weight and material properties. When the tester performs the test, the wrinkles may cause inconsistent burning levels at the test points, thus affecting the experimental data. The device includes a testing box, a support frame fixed to the bottom inner wall of the testing box, a support frame rotatably mounted on the support frame, four guide rails on the support frame, a first screw rotatably mounted in each guide rail, a first slider screwed onto the first screw and slidably connected to the guide rail, a gripper for holding the wallcovering on the first slider, and an ignition component for burning the wallcovering slidably mounted inside the testing box.

[0004] The aforementioned patent includes an ignition component that can perform a combustion test on the fabric held in the grippers. However, the fabric still produces smoke during combustion. Since there is no smoke extraction and purification component, the smoke is directly emitted into the air, causing environmental pollution. Therefore, a flame-retardant detection device for wallpaper is needed that can extract and purify the smoke produced when the fabric is burning. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing traditional wallcovering flame retardant testing devices, where the fabric produces smoke during combustion, and the lack of smoke extraction and purification components results in the smoke being directly released into the air, causing environmental pollution. Therefore, this invention proposes a wallcovering flame retardant testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wall covering flame retardant testing device, comprising a testing box, a fixing device provided on the outside of the testing box, the fixing device comprising a fixing frame, the outside of the fixing frame being fixedly connected to the testing box, an outer plate being fixedly connected to one end of the fixing frame, an air extraction component being fixedly connected to the inner side of the outer plate, T-shaped grooves being provided on both sides of the outer plate, T-shaped plates being slidably connected inside the T-shaped grooves, baffles being fixedly connected to one end of the two T-shaped plates, a lower mounting plate being fixedly connected to one side of the baffle, a filter screen being slidably connected to the inner side of the lower mounting plate, a middle mounting plate being fixedly connected to one side of the baffle, and a primary activated carbon plate being slidably connected to the inner side of the middle mounting plate.

[0007] The effect achieved by the above components is that the baffle is pulled away from the outer plate by the pulling force, so that the lower mounting plate and the middle mounting plate drive the filter screen and the first-stage activated carbon plate to move respectively.

[0008] Preferably, an upper mounting plate is fixedly connected to one side of the baffle, and a secondary activated carbon plate is slidably connected to the inner side of the upper mounting plate.

[0009] The effect achieved by the above components is that they achieve the effect of assembling a secondary activated carbon plate onto an upper mounting plate.

[0010] Preferably, both sides of the outer panel are fixedly connected to fixing blocks, and the top of the fixing blocks is fixedly connected to a telescopic rod.

[0011] The aforementioned components achieve the following effect: the telescopic rod is fixed to the fixing block, and the fixing block is fixed to the outer panel.

[0012] Preferably, an L-shaped block is fixedly connected to the output end of the telescopic rod, and a stop bar is fixedly connected to one side of the two L-shaped blocks that are close to each other.

[0013] The effect achieved by the above components is that the movement of the L-shaped block drives the extension and retraction of the output end of the telescopic rod, thereby moving the stop rod.

[0014] Preferably, the arc surface of the telescopic rod is fitted with a spring, and the two ends of the spring are fixedly connected to the fixed block and the L-shaped block, respectively.

[0015] The effect achieved by the above components is to prevent the spring from deforming during the stretching or contraction process.

[0016] Preferably, the outside of the testing box is provided with a rotating device, which includes two fixed through rods. The two fixed through rods are fixedly connected to the testing box on their sides that are close to each other, and a round rod is rotatably connected inside the fixed through rods.

[0017] The effect achieved by the above components is that the round rod rotates within the fixed through rod.

[0018] Preferably, both ends of the round rod are fixedly connected to connecting plates, and a pull rod is fixedly connected to the side of the two connecting plates that are close to each other.

[0019] The effect achieved by the above components is that the movement of the pull rod causes the connecting plate to rotate around the rod as the center.

[0020] Preferably, the arc surface of the pull rod is fixedly connected with an anti-slip sleeve, which is made of rubber.

[0021] The effect achieved by the above components is to increase friction by implementing anti-slip sleeves.

[0022] Preferably, the arc surface of the anti-slip sleeve is interference-fitted with a rubber groove plate, and the side of the two rubber groove plates that are close to each other is fixedly connected to the test box.

[0023] The effect achieved by the above components is that the anti-slip sleeve and the rubber groove plate are compatible.

[0024] In summary, the beneficial effects of this utility model are as follows:

[0025] In this invention, a fixing device is used to extract and purify the smoke generated during fabric testing. The extraction component is activated to purify the smoke from the testing chamber through a filter, a primary activated carbon plate, and a secondary activated carbon plate. This fixing device solves the problem of traditional wallcovering flame retardant testing devices where smoke is generated during combustion and, due to the lack of a smoke extraction and purification component, the smoke is directly released into the air, causing environmental pollution.

[0026] In this invention, a rotating device is used to apply tension to the anti-slip sleeve when the testing device needs to be moved, thereby rotating the pull rod. The continuously applied tension can move the testing box. The rotating device solves the problem that a traditional wallpaper flame retardant testing device is inconvenient to move because there is no external force-bearing point.

Detailed Implementation

[0032] Reference Figure 1 As shown, this utility model provides a technical solution: a wall covering flame retardant testing device, including a testing box 1, a fixing device 2 on the outside of the testing box 1, and a rotating device 3 on the outside of the testing box 1.

[0033] The following section will describe in detail the specific setup and function of its fixing device 2 and rotating device 3.

[0034] Reference Figure 2 and Figure 3As shown in this embodiment: the fixing device 2 includes a fixing frame 201, the outside of which is fixedly connected to the detection box 1. An outer plate 202 is fixedly connected to one end of the fixing frame 201. An air extraction component 206 is fixedly connected to the inner side of the outer plate 202. T-shaped grooves 203 are provided on both sides of the outer plate 202. T-shaped plates 204 are slidably connected inside the T-shaped grooves 203. Baffles 205 are fixedly connected to one end of each T-shaped plate 204. A lower mounting plate 207 is fixedly connected to one side of the baffle 205. A filter screen 208 is slidably connected to the inner side of the lower mounting plate 207. A middle mounting plate 209 is fixedly connected to one side of the baffle 205. A primary activated carbon plate 210 is slidably connected to the inner side of the middle mounting plate 209. This achieves the effect of the baffle 205 being pulled away from the outer plate 202, causing the lower mounting plate 207 and the middle mounting plate 209 to respectively drive the filter screen 208 and the primary activated carbon plate 210 to move. A top mounting plate 211 is fixedly connected to one side of the baffle 205, and a secondary activated carbon plate 212 is slidably connected to the inner side of the top mounting plate 211. This achieves the effect of the secondary activated carbon plate 212 being assembled on the top mounting plate 211. Fixing blocks 213 are fixedly connected to both sides of the outer plate 202, and a telescopic rod 214 is fixedly connected to the top of each fixing block 213. This achieves the effect of the telescopic rod 214 being fixed to the fixing block 213, and the fixing block 213 being fixed to the outer plate 202. An L-shaped block 216 is fixedly connected to the output end of the telescopic rod 214, and a stop rod 217 is fixedly connected to the side of the two L-shaped blocks 216 that are close to each other. This achieves the effect of the L-shaped blocks 216 moving to extend or retract the output end of the telescopic rod 214, causing the stop rod 217 to move. A spring 215 is fitted onto the arc surface of the telescopic rod 214, and both ends of the spring 215 are fixedly connected to the fixing block 213 and the L-shaped block 216, respectively. The telescopic rod 214 achieves the effect of preventing the spring 215 from deforming during the stretching or contraction process.

[0035] Reference Figure 4 As shown in this embodiment: the rotating device 3 includes two fixed through rods 31. The two fixed through rods 31 are fixedly connected to the detection box 1 on their sides, and a round rod 32 is rotatably connected inside the fixed through rods 31. This achieves the effect of the round rod 32 rotating within the fixed through rods 31. Connecting plates 33 are fixedly connected to both ends of the round rod 32, and a pull rod 34 is fixedly connected to the side of the two connecting plates 33 that are close to each other. This achieves the effect of the pull rod 34 moving to drive the connecting plate 33 to rotate around the round rod 32. An anti-slip sleeve 35, made of rubber, is fixedly connected to the arc surface of the pull rod 34. This achieves the effect of the anti-slip sleeve 35 increasing friction. A rubber groove plate 36 is interference-fitted to the arc surface of the anti-slip sleeve 35, and the side of the two rubber groove plates 36 that are close to each other is fixedly connected to the detection box 1. This achieves the effect of the anti-slip sleeve 35 and the rubber groove plate 36 being compatible.

[0036] Working principle: When it is necessary to purify the fumes generated during fabric testing, the operator first starts the extraction component 206 via the fixing device 2. The extraction component 206 draws the fumes in the testing chamber 1 through the fixing frame 201 into the cavity where the outer plate 202 and baffle 205 are installed. The fumes then pass through the filter plate, the primary activated carbon plate 210, and the secondary activated carbon plate 212 in sequence, thereby purifying the particulate matter and toxic substances in the fumes. The purified fumes can then be discharged from the extraction component 206. Through the fixing device 2, the problem of traditional wallcovering flame retardant testing devices being unable to purify the fumes during combustion, resulting in direct emission of fumes into the air and causing environmental pollution, is solved.

[0037] When the testing device needs to be moved using the rotating device 3, the operator first pulls the anti-slip sleeve 35 to disengage it from the rubber groove plate 36, then holds the anti-slip sleeve 35 and applies continuous pulling force to move the pull rod 34. This causes the connecting plate 33 to rotate the round rod 32 within the fixed through rod 31. After rotating to a certain angle, the continuously applied pulling force can move the testing box 1. The rotating device 3 solves the problem of traditional wall covering flame retardant testing devices being difficult to move because there are no external leverage points.
