Description

Technical Field

[0001] The utility model relates to daily necessities, in particular to a negative pressure sucker type hook. Background Art

[0002] For convenience, many families and offices use adhesive hooks. There are mainly two types of adhesive hooks: glue paste and sucker paste. The glue paste type hook generally has a hook base, and a layer of glue is provided on the back of the hook base. The glue is covered with a glue film. When in use, only need to tear off the film and directly paste it on the wall. However, the glue layer cannot be used again after being used once, and the hook can only be fixed in one position and cannot be moved to another position, which is troublesome and wasteful. While the sucker type hook can be reused, but if the sealing performance is not good, it is easy for air to enter and cause it to fall off, which cannot meet the practical needs. Content of the Utility Model

[0003] To solve the above technical problems, the technical solution provided by the utility model is: a negative pressure sucker type hook, including a sucker main body and an accessory connection part arranged at the lower part of the sucker main body. The sucker main body includes an annular side wall. One side of the annular side wall is covered with a front end face, and the other side is a sucker opening. A through hole is penetrated through the middle of the front end face. A connecting column is penetrated through the through hole. A paste piece covering the sucker opening is arranged at one end of the connecting column located at the sucker opening, and the other end extends out of the through hole and is connected with a locking cover matched with it.

[0004] The advantages of the utility model compared with the prior art are: by arranging the connecting column, during the process of screwing the connecting column and the locking cover tightly, the center of the paste piece is driven to bend inwards, so that negative pressure is formed on the surface of the paste piece, increasing the tightness of the connection between the paste piece and the wall surface, which is simple and practical.
