The utility model relates to the technical field of textile fabrics, in particular to a textile fabric shrinkage rate detection box which comprises a box body, a box door, a first shell, a second shell and a supporting frame, the box door is rotatably arranged on the outer wall of the side edge of the box body, the first shell is arranged on the outer wall of the side edge of the box body, and the second shell is arranged at the top end of the first shell. A steam mechanism is arranged above the box body, and a measuring mechanism is installed on the inner wall of the side edge of the supporting frame. The small vacuum pump is used for pumping air, so that the air suction plate generates suction force, redundant steam generated in the ironing process is sucked, the steam is pumped into the cooling box and then cooled into water again, and then the cooled water is pumped back into the water tank again through the small water pump. Therefore, the interior of the box body can be kept dry after ironing is finished, the next detection is prevented from being affected, and the working efficiency is improved.

The utility model belongs to the field of negative ion detection technology discloses air negative ion automatic observation appearance, including the casing, the inside fixed mounting of casing has negative ion sensor and controller, negative ion sensor sets up two, can alternately use two negative ion sensors all with controller electricity is connected, the side fixed embedding of controller has display screen, display screen and controller electricity is connected, the utility model sets up two alternately usable negative ion sensors, through controller time -sharing switch working condition. When one sensor detects, another can start fan reversal and carry out self -cleaning, avoid single sensor failure and lead to equipment shutdown, satisfy long -term continuous monitoring demand, reduce maintenance influence to monitoring continuity, the reverse convex sealing ring between lower porcelain cover and lower insulating cover is under the spring pressure effect, closely fits lower porcelain cover inner wall and lower insulating cover bottom, effectively prevents air leakage, guarantees the detection airflow stability.

The utility model relates to the field of gas detection, and discloses a concentration proportioning box for gas detection, which comprises a concentration proportioning box body, a box cover plate is mounted on the upper surface of the concentration proportioning box body, an exhaust port is fixedly mounted in the middle of the top end of the box cover plate, a gas detector is arranged above the exhaust port, and a detection port is fixedly connected to the bottom end of the gas detector. Connecting pipes sleeve the outer surfaces of the exhaust port and the detection port, a fixed frame is fixedly mounted on the upper surface of the box cover plate close to the outside of the exhaust port, and a plurality of movable supporting rods are hinged to the outer surface of the fixed frame; through the unfolding and folding design of the movable supporting rod, the connecting pipe can be conveniently and rapidly installed on the outer surfaces of the exhaust port and the detection port during unfolding; when the gas leakage detection device is folded, the transparent elastic water retaining bag accurately wraps the connection position of the connection pipe, the exhaust port and the detection port, and is matched with the injected detection water, so that whether gas leakage exists at the key position or not can be intuitively judged through bubbles, and the detection accuracy is remarkably improved.

This invention relates to the field of cable testing technology, specifically a cable connection testing device for flame-retardant cable installation, comprising: a base plate; a positioning and guiding mechanism, wherein the positioning and guiding mechanism for positioning and guiding the cable under testing is disposed at the top of the base plate; a testing mechanism, wherein the testing mechanism for testing the surface flatness of the cable is disposed at the top center of the base plate; and a cleaning mechanism; the guiding component in the positioning and guiding mechanism of this device can be freely adjusted according to the cable specifications, enabling better guidance of the cable, while the positioning component can center the cable, ensuring that the cable is in a centered state during testing, thus improving the accuracy of testing; under the action of the transmission component, the cleaning component can rotate synchronously with the guiding component, allowing the cleaning block to rotate and clean, preventing dust and impurities on the cable surface from affecting the testing of the cable surface flatness.
