TECHNICAL FIELD

[0001] The utility model relates to the field of sucking disc, especially a sucking disc hook. BACKGROUND

[0002] The sucking disc hook sets the pulling piece in the middle of the sucking disc, and the pulling piece is rotationally connected with the screw cap, and the air in the middle of the sucking disc is squeezed out through the screw rod transmission, so that the sucking disc is attached to the surface.

[0003] However, in order to avoid the screw cap from falling off during rotation, the existing sucking disc hook generally sets a limiting part on the pulling piece, which is clamped in the screw cap to prevent the screw cap from falling off during rotation. However, in the actual production process, the above design method is prone to enlarge the hole diameter of the screw hole on the screw cap during installation, resulting in that the screw hole and the external thread on the pulling piece cannot be engaged, and the product failure rate is high.

[0004] For example, the patent document with the announcement number CN221730269U discloses a sucking disc hook, which comprises a main body formed by integrally connecting a sucking disc part and a hook part, a sucking disc insert penetrating through the middle of the sucking disc part, a sucking disc arranged at one end of the sucking disc insert, and a rotating cover fixedly connected to the other end of the sucking disc insert. The side of the sucking disc part close to the rotating cover has a stroke groove, the rotating cover and the stroke groove are in abutment, the stroke groove forms an included angle with the sucking disc part, and the hook part is fixedly connected with a hook.

[0005] The above technology limits the clamping of the pin on the screw cap. During installation, the screw hole of the screw cap is prone to be enlarged, the screw hole and the external thread on the sucking disc insert cannot be engaged, and the product failure rate is high. INVENTION CONTENTS

[0007] The technical solution adopted by the utility model to solve the problem is: a sucking disc hook, comprising: a sucking disc, a rotating cover, and a hook part, the sucking disc and the rotating cover are transmissionally connected through a pulling piece, an installation ring is arranged between the sucking disc and the rotating cover, the installation ring is fixedly connected to the sucking disc, an annular groove is formed on the installation ring, a plurality of elastic buckles are arranged on the rotating cover, and the elastic buckles are clamped with the annular groove.

[0008] As a further improvement of the above technical solution, an annular part is further arranged on the installation ring, and the annular part is bonded to the sucking disc.

[0009] As a further improvement of the above technical solution, a connecting ring is sleeved on the installation ring, an installation groove is formed on the connecting ring, a connecting shaft is arranged on the hook part, and the connecting shaft is matched with the installation groove.

[0010] As a further improvement of the above technical solution, the suction disc is a flat suction disc.

[0011] As a further improvement of the above technical solution, the suction disc is made of rubber material.

[0012] As a further improvement of the above technical solution, the pulling member is provided with a screw rod, the screw rod is threadedly connected with an inner stud provided in the screw cap.

[0013] As a further improvement of the above technical solution, the mounting ring is provided with a pressing ring, and the connecting ring is rotatably connected to the pressing ring.

[0014] As a further improvement of the above technical solution, the bottom of the hook portion is provided with an abutting block.

[0015] The utility model discloses the beneficial effect is: the utility model discloses the annular groove is set up on the mounting ring, and a plurality of elastic buckles are equipped on the screw cap, and the elastic buckle is clamped with the annular groove, so that the suction disc hook can be smoothly disassembled integrally when rotating and disassembling, prevents the screw cap from separating and falling off and reduces the defective rate at the same time.
