A building indoor temperature and humidity gradient measuring device comprises a supporting mechanism and a measuring instrument installed on the supporting mechanism. The supporting mechanism comprises a supporting disc, a lower support, a supporting rod and containing assemblies evenly distributed on the supporting rod. The lower support is hinged to the bottom of the supporting disc, the supporting rod is longitudinally arranged on the top of the supporting disc, and the containing assembly comprises a hanging piece and a breathable flexible bag; the hanging piece is detachably installed on the supporting rod, a drawing rope capable of contracting an opening of the breathable flexible bag is arranged at the opening of the breathable flexible bag, and the drawing rope can be hung on the hanging piece; and the measuring instrument is placed in the breathable flexible bag. The measuring instrument is placed in the breathable flexible bag, so that air can penetrate through the breathable flexible bag to ensure the measuring effect, and the outside of the measuring instrument can be prevented from being abraded. When in use, the breathable flexible bag provided with the measuring instrument can be hung at a corresponding height according to the height required to be measured, so that the temperature and humidity of different indoor heights can be measured.

The application provides a powder collector with sterilization function, which comprises an upper chamber arranged above a top plate of a shell, a lower chamber arranged below a bottom plate of the shell, a discharge pipe arranged at a lower end of the lower chamber, an inlet pipe arranged on the upper chamber, an air outlet pipe arranged on a side wall of the shell and connected with an air blower at a terminal end of the air outlet pipe, a plurality of filter pipes arranged through the bottom plate and the top plate of the shell at two ends thereof, the upper ends of the filter pipes being communicated with the upper chamber and the lower ends of the filter pipes being communicated with the lower chamber, a plurality of ultraviolet light tubes arranged in the filter pipes in one-to-one correspondence, the upper ends of the ultraviolet light tubes being arranged through the top of the upper chamber, and a power connector arranged on the top of the ultraviolet light tube. The powder collector is combined with a jet mill to form a powder crushing system. The powder crushing system can sterilize the powder during the collection of the finished powder, so that the quality of the finished powder is improved.

The application discloses a portable dust detector, which comprises a detection outer cylinder, a holding handle arranged at one end of the detection outer cylinder, a detection channel arranged in the middle of the detection outer cylinder and penetrating in the radial direction, a first installation chamber and a second installation chamber arranged on the detection outer cylinder and communicating with the detection channel, a light source, a collimating lens and a light blocking sheet sequentially arranged in the first installation chamber, a small hole arranged in the center of the light blocking sheet and the light blocking sheet arranged on the side close to the detection channel, a light trap, a focusing lens group and a light receiver sequentially arranged in the transmission direction of the light in the second installation chamber, the light trap arranged on the side close to the detection channel, the light trap arranged in the middle of the focusing lens group and corresponding to the small hole on the light blocking sheet, a battery arranged in the holding handle, an axial threading hole arranged on the detection outer cylinder, and the light receiver and the light source connected with the battery. The portable dust detector is simple to use and portable.

The utility model discloses a threading and embedding device, and relates to the technical field of building construction. Comprising a wire embedding frame, a through groove is formed in the wire embedding frame, multiple sets of inserting holes are formed in the left and right side walls of the front and rear ends of the through groove, fixing bolts are installed in the inserting holes, pulleys are installed on the circumferential surfaces of the middles of the fixing bolts, fixing rods are installed at the lower ends of the inner walls of the left and right sides of the wire embedding frame, and the circumferential surfaces of the fixing rods are movably connected with the pulleys through bearings. Connecting plates are movably installed at the tops of the front end and the rear end of the wire embedding frame, electric telescopic rods are installed on the lower surfaces of the connecting plates, connecting blocks are installed at the ends, away from the connecting plates, of the electric telescopic rods, a groove is formed in the middle of the bottom end of each connecting block, and two rotating shafts are installed in each groove; a limiting groove is formed in the middle of the inward side of the push rod, a limiting rod is installed in the limiting groove, limiting blocks are installed at the left end and the right end of the limiting rod, sliding grooves are formed in the front side wall and the rear side wall of the limiting groove, and the limiting blocks are movably installed in the sliding grooves.

The utility model provides a connecting structure of a steel plate net and an external scaffold. The connecting structure is characterized in that the steel plate net is movably mounted on the outer side of a vertical rod of the external scaffold through a movable connecting mechanism; when the installation height of the steel plate net needs to be adjusted, the movable connecting mechanism is opened and drives the steel plate net to extend outwards, and then the height is adjusted upwards or downwards. According to the scheme, the defect that in the construction process, a steel plate net cannot be locally moved after being installed on a vertical rod is overcome, and the problem that when some construction components such as steel wire ropes and wall passing steel pipes penetrate through an external scaffold protection net from a building body, the construction components cannot be locally moved is solved; and the problem that the use effect of the external scaffold protective net is affected due to the fact that the formed avoiding gap is too large due to the fact that part of the steel plate net needs to be integrally dismantled to form the avoiding gap is solved. By means of the design, the steel plate net only needs to be finely adjusted at the original position, the avoiding gap with the reasonable size is formed, and the purposes that it is guaranteed that a construction component can penetrate through the steel plate net, and use of the external scaffold protective net is not affected are achieved.
