Description

Technical Field

[0001] This utility model belongs to the field of telescopic rod technology, specifically relating to a telescopic rod with a suction cup. Background Technology

[0002] Existing no-drill telescopic poles are basically composed of telescopic tubes of different sizes with bases at both ends. The telescopic tubes extend the length of the pole, and the positions of the tubes are fixed by a structure to adapt to various usage scenarios. Springs increase the pressure on the two walls, and the TPE or PVC pads at the bases increase the friction with the walls. This allows the telescopic pole to be supported between two walls without drilling and can withstand a certain weight without sagging. However, these types of telescopic poles are prone to sliding on smooth walls, and heavy objects may slip off. Therefore, it is very important to develop a telescopic pole with suction cups. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a telescopic rod with a suction cup, comprising:

[0004] The telescopic pole body includes at least two telescopically connected poles; several adjustment holes can be opened on one of the poles, and an adjustment protrusion can be installed on one of the poles. The adjustment protrusion can extend or retract in different adjustment holes, or the two telescopic poles can be connected by threads to achieve extension or retraction.

[0005] At least one suction cup assembly is disposed at at least one end of the telescopic rod body, the suction cup assembly comprising:

[0006] The suction cup body is equipped with a driving component;

[0007] The first support member has a first through hole;

[0008] The rotating component has a second through hole that mates with the first through hole. The rotating component has at least one driving surface. The driving component passes through the first through hole and the second through hole to form a driving part. The driving part is placed on the driving surface. The rotating component rotates to drive the driving part with the driving surface, thereby causing at least part of the suction cup body to move axially to control the adsorption or release of the suction cup assembly.

[0009] The outer wall of the rotating component is also provided with several raised rings to prevent the entire surface of the rotating component from being electrostatically attracted to the first support component and thus unable to rotate.

[0010] Through the above technical solution, during the rotation of the rotating part, the driving surface will rise or fall, which will control the axial movement of the driving part. The axial direction is the central axis of the driving part, which can control the movement of the middle part of the suction cup body, thereby controlling the air pressure in the cavity between the suction cup and the wall, and thus achieving suction.

[0011] At least one elastic element is provided between the suction cup body and the first support member. The elastic element includes a spring and can be sleeved outside the driving member.

[0012] A limiting structure is provided between the driving member and the first support member to restrict the rotation of the driving member. The limiting structure includes at least one limiting surface formed in the first through hole and a stop surface formed on the outer wall of the driving member that mates with the limiting surface; or the limiting structure is: the first through hole is an irregular hole, the cross section of the driving member is a shape that mates with the irregular hole, or is another shape that cannot rotate within the irregular hole.

[0013] The driving component has a third through hole, and a pin is provided in the third through hole. There are two driving surfaces, and the two ends of the pin form the driving part.

[0014] The first support member is provided with a rotating groove, and the rotating member is at least partially positioned within the rotating groove.

[0015] It also includes a cover connected to the first support member, the cover or the first support member having two switch slots, and the rotating member having two switch elements that protrude from the switch slots. The cover can be fixed to the first support member by fasteners. The two switch elements are symmetrically arranged.

[0016] The above technical solution allows for symmetrical arrangement of the switching components, facilitating rotation during use.

[0017] The driving surface includes an inclined surface and / or an arc surface, and a downward limiting groove is connected to the top end of the inclined surface and / or arc surface. A first mounting groove is provided on the cover, and the end of the telescopic rod body is mounted in the first mounting groove. A connector is also included, which is fixedly connected to the cover. A second mounting groove is provided on the connector, and the end of the telescopic rod body is mounted in the second mounting groove.

[0018] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure and can realize the installation of telescopic rods without drilling. Attached Figure Description
