The invention relates to a rotary control type stop valve which comprises a valve body, a valve rod, an air inlet connector and an air outlet connector. A valve clack is arranged at the bottom of the valve rod, the air inlet connector extends into the valve body and is provided with a sealing seat, the sealing seat is vertically arranged upwards, a step groove is formed in the upper surface of the sealing seat, and a protrusion matched with the groove is arranged on the lower end face of the valve clack. The rotary control type stop valve with the technical scheme can effectively stop medium flowing, saves labor and is convenient to use.

The invention belongs to the technical field of logistics packaging, in particular to a logistics box. The logistics box can be repeatedly utilized, unnecessary resource waste is avoided, the treatment difficulty of express garbage is effectively reduced, and the positive effects on environment protection are achieved. The logistics box is arranged to be of a foldable structure, and collection andstorage of recipients are facilitated, so that express items are returned to courier services companies in a unified manner. According to the logistics box, a box body and a box cover are connected through disposable lock catch components, once the logistics box is opened, the logistics box is hard to restore without dedicated equipment, the risk that express items are opened by other people in the transport process is effectively avoided, and the confidentiality effect is improved; and inflatable airbags and an air pressure detection device are arranged in the logistics box, it can be ensured that the airbags fully presses the express items by detecting the air pressure of the airbags, the express items are prevented from shaking in the transport process, and the protection effect on theexpress items is effectively improved.

The invention discloses an insulating irregular part wet method forming device which comprises an irregular part core mold and an elastic forcing device, wherein the irregular part core mold comprises a cylindrical core mold and an arched core mold, the cylindrical core mold is arranged in the radial direction of an arc surface of the arched core mold, the combination part of the cylindrical core mold and the arched core mold is a fillet transition surface, the elastic forcing device comprises a forcing plate and an irregular part pressure plate which are oppositely arranged, the forcing plate is fixedly installed at the end of the cylindrical core mold, the irregular part pressure plate is provided with an arc surface matched with the arched core mold and a through hole for being sleeved with the cylindrical core mold, the edge of the through hole is adapted to a shape of the fillet transition surface, and a forcing spring is arranged between the forcing plate and the irregular part pressure plate. According to the insulating irregular part wet method forming device disclosed by the invention, the transition part of an upper body and a lower body is good to combine, so that the qualified rate of a product is increased.

The object of the present invention is to provide a motor casing and a motor stator structure, including a heat dissipation device, the heat dissipation device is composed of a vapor chamber, and the vapor chamber is uniformly distributed on the outside of the first casing and the second casing. The plate is fully in contact with the air to dissipate heat and quickly dissipate heat; the bridge assembly includes a mounting plate, a first connecting column, a second connecting column and a spring, the mounting plate is slidably installed in the first housing, and the first connecting column and the second connecting column The column is slidably installed on the mounting plate after being connected by a spring. Under the action of the spring, the stator structure on both sides is fixed, so that the iron chips are fully compressed without vibration. At the same time, the bridge component made of conductive material makes the two The stator structures on both sides are connected to ensure the normal operation of the stator structures on both sides.

The invention discloses a telescopic hanger, which comprises a top box body. The top box body is provided with symmetrical inner cavities for placing steel cables. Between the inner cavities for placing steel cables, there is a middle box located in the top box body. The inner cavity, the lower end wall of the middle inner cavity is connected with a symmetrical penetrating inner cavity, the penetrating inner cavity is arranged vertically, the lower side of the top box is provided with a bottom box, and the two sides of the bottom box are A symmetrical side fixing block is fixed on the side end surface, and a box body is provided for sliding clamping in the bottom box body. The inside of the box body is a hollow structure, and a symmetrical transmission inner cavity is arranged in the box body. A number of unwinding devices are provided in the inner cavity and the middle inner cavity, and the unwinding device is provided with a penetrating inner cavity. The equipment can respectively make the bottom box body and the box body telescopically lift, and use the two-stage bottom box The body and the box body can use the matching hook and the hanging hook to hang articles respectively, and have good firmness.

The invention discloses a high-vacuum degree rotary sealing mechanism. The high-vacuum degree rotary sealing mechanism comprises a sealing sleeve, a pressure head, a rotary piece, at least one first soft sealing ring, at least one hard compression ring, and a fastener, wherein a first through hole is formed in the bottom of the sealing sleeve and the axial direction of the first through hole is parallel to that of the sealing sleeve; a second through hole is formed in the pressure head to penetrate through the pressure head; the rotary piece is put through and pivoted in the first through hole and the second through hole; the at least one first soft sealing ring hermetically sleeves the rotary piece and is located in the sealing sleeve; each compression ring hermetically sleeves the rotary piece; each compression ring is located on one side, close to the opening of the sealing sleeve, of the corresponding first soft sealing ring; the pressure head is detachably fixed at the opening of the sealing sleeve by use of the fastener, and the fastener is used for driving the pressure head to be switched between a position where the pressure head extends into the sealing sleeve and props against the compressing ring and a position where the pressure head is far away from the sealing sleeve and separated from the compression ring. The high-vacuum degree rotary sealing mechanism is capable of keeping a relatively high vacuum degree in a vacuum chamber and realizing an excellent dynamic sealing effect under the circumstance that the rotary piece rotates.
