The left side of the top end of the sun shield is provided with a connecting plug, the connecting plug and the fixed inserting opening are of a clamping structure, and when the sun shield is damaged, the sun shield and the fixed inserting opening can be rapidly separated under the action of the connecting plug and the fixed inserting opening.

The invention is applicable to the technical field of electronic devices and provides a touch screen and an electronic device. The touch screen comprises a cover plate and sensing film which are superposed to form a whole, the area of the sensing film is smaller than that of the cover plate, and the position of the sensing film is staggered with one end or the opposite ends of the cover plate. Theelectronic device comprises the touch screen and a middle frame. A first connecting portion and a second connecting portion which are different in height can be arranged in a middle frame of the electronic device, so that the sensing film higher than the plane of the cover plate can be superposed on the lower second connecting portion, or the middle frame of the electronic device is correspondingly provided with a first connecting portion and a second connecting portion which are different in height. The common film lower in cost is firstly bonded on the cover plate and then is connected withthe first connecting portion, while the sensing film is directly bonded on the second connecting portion, and the connection between the touch screen and the middle frame is not affected. It is thusclear that the material cost of the sensing film is saved, and the connection between the touch screen and the middle frame is not affected.

The invention discloses a connection structure of a heat exchange tube and a tube plate. The connection structure comprises the tube plate and the heat exchange tube. The connection structure is characterized in that: a section of annular sealing groove and a section of internal thread are formed on an inner wall of a heat exchange tube hole in the tube plate; a distance between the internal thread and a heat exchange tube orifice (namely an end face of the tube plate) is smaller than the distance between the annular sealing groove and the heat exchange tube orifice; an O-shaped sealing ring is sleeved on the inner section of the heat exchange tube hole of the heat exchange tube; and the O-shaped sealing ring is placed in the annular sealing groove and in fit with the annular sealing groove and the heat exchange tube. The connection structure also comprises a threaded plug, wherein threads which are in fit with the internal thread of the tube hole in the tube plate are formed on an outer wall of the threaded plug; a hollow hole is formed inside the threaded plug; the inner wall of the hole is in fit with the outer wall of the heat exchange tube; a shrinkage step is arranged in thehole; a clearance is reserved between the step and the heat exchange tube orifice; and the material hardness of the threaded plug is lower than that of the tube plate. In the situation that the heat expansion amount of the heat exchange tube cannot influence the connection of the tube plate and the heat exchange tube, the connection structure has excellent sealing performance.

The invention discloses a mill, which is composed of a frame, an automatic feeding machine, a particle material cylinder, a vibrating feeder, a feeding pipe, a mill, a fan, a material suction pipe, a cyclone separator, a combined shut-off fan, Composed of rotating frame, counterweight, separating screen and soft interface, the upper cover and the main shaft shell of the mill are respectively fixed on the upper and lower sides of the grinding disc shell, the main shaft is installed in the main shaft shell through the bearing, and the lower cutter head is installed on the movable There is a gap between the upper and lower cutter heads and the moving disk, the moving disk and the main shaft are fixed, the upper cutter head is fixed on the fixed seat, and there is a gap between the upper cutter head and the fixed seat, and the grinding disc shell is provided for cooling separately.

The present invention relates to a secret leakage protection method, which includes listening to an associated frame or data frame broadcast when a terminal connects to an illegal AP; acquiring the terminal feature of the terminal according to the associated frame or data frame; detecting whether the terminal feature exists in the preset If it is in the preset terminal feature database, then implement leakage protection on the terminal. With this leak protection method, since the terminal feature database stores the terminal features of terminals capable of connecting to legitimate APs, the leak protection can only be implemented for terminals that exist in the terminal feature database, and for terminals that are not in the terminal signature database, the Leakage protection is not implemented, so that it will not affect the connection of terminals that are not in the terminal signature database to illegal APs, that is, it will not affect the connection of terminals of other enterprises to their APs, reducing misjudgment.

The invention relates to an ice making drum which comprises an ice making drum body. A bottom plate mounting drum is arranged at the lower end of the ice making drum body, and is provided with a mounting drum inner wall hermetically matched with the periphery of a corresponding bottom plate by means of a seal ring. Hook penetration holes for allowing elastic hooks on the bottom plate to pass are formed in the bottom of the ice making drum body and on the inner side of the bottom plate mounting drum. A push rod device, which can move in the up-and-down direction to push the upper ends of the elastic hooks to separate hook parts of the elastic hooks from the ice making drum body, is arranged on the ice making drum. Through the adoption of the ice making drum, the problem that in the prior art, an ice making drum and a bottom plate need to be in frozen connection in a refrigerator in advance, so that the ice making process is tedious is solved.
