The utility model discloses a temperature -controlled magnetic stirrer, specifically related to the technical field of stirrer, including stirring mechanism, the outside of stirring mechanism is provided with cover plate mechanism and fetch mechanism, the stirring mechanism includes control base plate and installs the placement tray above control base plate, and the upper portion of placement tray is placed with container, and the container is placed with stirrer, and the upper portion fixedly connected with support and auxiliary support bar of control base plate. The utility model discloses the cooperation of auxiliary support bar, cover plate mechanism and fetch mechanism, and the diagonal line distribution design of support and auxiliary support bar restricts the rotation angle of cover plate mechanism, makes container rotate 135 after and automatically centring to the center of placement tray and clamping positioning, and the cooperation of cover plate down pressure plugging container port prevents liquid from throwing out when stirring, and fetch mechanism utilizes the magnetic attraction of metal block and stirrer and realizes quick adsorption and release, and the pickup sleeve rod of its columnar structure adopts high temperature -resistant corrosion -resistant material, and simplifies the operation process and improves cleaning maintenance efficiency.

The utility model relates to a multifunctional steam milk bar, including the tubular body, one end connects the steam source, and the other end sets up the blast hole, sleeve, sleeve sets up on the tubular body, the sleeve and the tubular body form the air cavity between, and the sleeve sets up the inflation hole intercommunication air cavity on, around the inflation hole, the surface of sleeve sets up the adjusting cylinder, adjusting sleeve, set up in the adjusting cylinder, adjusting sleeve sets up the air inlet groove A on, the air inlet groove A intercommunication inflation hole, adjusting head, extends into the adjusting cylinder, adjusting head sets up the air inlet groove B on, wherein, the sleeve opening sets up close to the blast hole one end, and the other end of sleeve and tubular body between seal connection, around the axis of rotation adjusting head adjusting head, the air inlet groove A and the air inlet groove B intercommunication or break off, the utility model discloses through the adjusting head on the sleeve, can intercommunication or break off the air inlet groove A and the air inlet groove B, realize the quick switching of multifunctional steam milk bar's work mode, and the switching mode is simple and quick, and the use efficiency of multifunctional steam milk bar is improved.

The utility model discloses a ship pipe hanger relates to ship field, including bottom plate and support, the bottom plate is fixedly installed on the upper end of support, bottom plate and support both sides are provided with round mouth, the inside of round mouth is provided with U-shaped ring, the inside of bottom plate far away from the support both sides is provided with anti-drop nut, the inside of support is provided with the anti-drop nut, and the inside of support is provided with the anti-drop nut. The two anti-disengaging nuts are both in threaded connection with the two sides of one end of the U-shaped ring, fastening nuts are rotationally installed on the two sides of the interior of the end, away from the bottom plate, of the support and are also in threaded connection with the two sides of one end of the U-shaped ring, and a mounting plate is integrally formed in the center position of the end, away from the support, of the bottom plate. Three buffer springs are fixedly mounted at the end, away from the bottom plate, of each mounting plate. By the adoption of the structure, the rotation angle of the anti-disengaging nut is effectively limited, looseness caused by excessive rotation of the anti-disengaging nut is prevented, and therefore the reliable anti-disengaging effect is achieved.

The application discloses a foot stand and furniture, which comprises two groups of support structures, the support structures comprising a first supporting leg, a second supporting leg parallel to the first supporting leg, a first connecting rod with a first caster, a second connecting rod with a second caster, and a switching device. The first connecting rod is rotationally connected with the first supporting leg through a first limiting hinge, and the second connecting rod is rotationally connected with the second supporting leg through a second limiting hinge. The switching device comprises a switching assembly and a connecting rod assembly, the first connecting rod is connected with the second connecting rod through the connecting rod assembly, and the switching assembly is arranged between the first connecting rod and the second connecting rod. The limiting hinge is locked when the connecting rod is rotated to a preset angle, so that the connecting rod is prevented from being excessively lifted to cause difficulty in use. The connecting rod assembly enables one connecting rod to synchronously drive the other connecting rod to move, so that the movement is ensured to be coordinated during the switching process. The switching between the moving state and the static state can be realized by controlling the locking and unlocking between the connecting rods through the switching assembly.
