5results about How to "Improve sealing function" patented technology

The utility model relates to the technical field of sterilization, and discloses a sterilization device for dairy product production, which comprises a shell, two electric push rods are fixedly connected in the shell, the bottoms of the two electric push rods are fixedly connected with the same scraping block, the top of the shell is fixedly connected with a motor, and the motor is fixedly connected with a motor. A motor is fixedly connected to the bottom of the shell, a vertical shaft is fixedly connected to the bottom of the motor, a plurality of stirring rods are fixedly connected to the outer side of the vertical shaft, two scraping rods are fixedly connected to the bottom of the vertical shaft, and a heating pipe is fixedly connected to the interior of the shell. The sterilization device for dairy product production has the advantages of being low in use cost, clean in discharging and the like, and solves the problems that when the sterilization device is used, most existing sterilization devices do not have a wall scraping function, so that the inner walls of the sterilization devices adhere to a large number of dairy products when the dairy products are discharged after sterilization is completed, and then the dairy products are wasted; and the use cost of the sterilization device is increased.

The utility model relates to the technical field of sampling tubes, in particular to a novel blood sampling tube which comprises a temporary support, a plurality of circular grooves are formed in the top of the temporary support, blood sampling tubes are placed in the circular grooves, and first annular anti-falling blocks and second annular anti-falling blocks are arranged on the outer walls of the blood sampling tubes. Four first rubber positioning sheets which are arranged in an annular array are arranged at the middle upper part of the inner wall of the circular groove, and two second rubber positioning sheets which are arranged in a bilateral symmetry manner are arranged at the positions, close to the bottom, of the inner wall of the circular groove. According to the novel blood sampling tube, a first annular anti-falling block and a second annular anti-falling block are arranged and are matched with a first V-shaped groove in a first rubber positioning piece and a second V-shaped groove in a second rubber positioning piece respectively, so that the movement of the blood sampling tube in the longitudinal direction and the transverse direction can be effectively limited, and the blood sampling tube is prevented from moving or sliding due to shaking; the stability of the sampling pipe is greatly improved, and the sampling pipe is particularly suitable for being used in transportation or bumpy environments.

The utility model discloses a cable explosion -proof box belongs to cable equipment technical field, including mounting spare and glue injection spare, two mounting spares can be relatively buckled and detachable connection to form explosion -proof box body, and the inside of explosion -proof box body forms sealed cavity, and the both ends of sealed cavity are provided with fixed line passageway, and fixed line passageway one end communicates sealed cavity, and the other end communicates outside, and fixed line passageway and sealed cavity coaxial setting, glue injection spare fixed connection in any mounting spare, and the glue injection passageway of being through being provided on glue injection spare, and glue injection passageway communicates sealed cavity with outside, is used to inject solidified explosion -proof glue in sealed cavity. The cable explosion -proof box through the design of mounting spare and glue injection spare, has realized the assembly of cable explosion -proof box convenientization and has dismantled, has effectively promoted the sealing and explosion -proof performance to cable and junction box interface, has guaranteed the stable safe operation of cable and related equipment.

The utility model provides a sealed enhancement type flushes the valve control device, including the valve disc, be provided with the valve cavity in the valve disc, be provided with the valve plate in the valve cavity, fixedly be provided with and the control pivot of valve cavity rotation connection on the valve plate, open the flush mouth that is opposite control pivot eccentric on the valve plate, the disc surface of valve disc is equipped with the through -hole that flush mouth cooperation uses is connected with valve cavity, the annular limit slot that is located valve plate both sides is seted up in the valve cavity, the annular limit slot and the coaxial heart of through -hole, in the utility model, set up the positioning ring that can slide in the annular limit slot, then set up the supporting spring on one side of positioning ring, set up the sealing rubber bushing that is opposite and the valve plate on the other side, the supporting spring is extruded to sealing rubber bushing continuously by positioning ring, when sealing rubber bushing wears, the supporting spring still can make sealing rubber bushing to valve plate add certain extrusion pressure, has the advantage that strengthens the sealing.

The application relates to the technical field of building adhesives, and particularly discloses a fire-retardant polyurethane two-component corner adhesive and a preparation method thereof; the fire-retardant polyurethane two-component corner adhesive comprises an A component and a B component; the A component comprises, in mass parts, first polyether polyol: 40-55 parts; first filler: 20-35 parts; first thixotropic agent: 1-5 parts; compounded fire retardant: 20-25 parts; modifier: 1-2 parts; catalyst: 0.004-0.008 parts; the B component comprises, in mass parts, curing agent: 35-45 parts; second polyether polyol: 1-5 parts; plasticizer: 8-12 parts; second filler: 40-50 parts; and second thixotropic agent: 1-2 parts; the fire-retardant polyurethane two-component corner adhesive has good fire-retardant function, high hardness, high toughness and high bonding strength; and the fire-retardant polyurethane two-component corner adhesive also has excellent sealing function, structure reinforcing function, shock-absorbing function, sound insulation function and heat insulation function.
