Description

Technical Field

[0001] This utility model relates to the field of mounting bases for shelves and towel racks, and specifically to a suction cup base. Background Technology

[0002] Existing suction cup bases all include a suction cup and a pull rod. When adsorbing, the pull rod is usually pulled by swinging an eccentric handle or by screwing on a screw cap. Some also include an insert handle, which is pulled by matching a wedge-shaped surface with a sliding pin on the pull rod. For the sake of overall aesthetics, the handle is often matched with the shape of the base after it is locked in place, thereby improving the overall appearance. However, this also makes it difficult to pull the handle out when unlocking is required. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a suction cup base that is compact, aesthetically pleasing, and easy to assemble and disassemble.

[0004] To address the above problems, the following technical solution is provided: a suction cup base, comprising a base, a suction cup on the back of the base, a pull rod extending through the base to the front of the base, and a sliding pin at the extended end of the pull rod; the base also comprises a slidable locking handle, the locking handle comprising a recessed unlocking part, an raised retaining part, and an inclined part connecting the unlocking part and the retaining part; when the locking handle slides from a first position to a second position, the sliding pin moves from the unlocking part through the inclined part to the retaining part to control the pull rod to pull the suction cup to generate negative pressure; the base also comprises a sliding unlocking handle relative to the base; when the unlocking handle slides from the first position to the second position, it abuts against the locking handle and pushes the locking handle to slide from the second position to the first position to achieve unlocking.

[0005] The present invention is further configured such that, when the locking handle is in the first position, it protrudes outward from the base contour, and when the locking handle slides from the first position to the second position, its main body contour is adapted to the base contour; when the unlocking handle is in the first position, its main body contour is adapted to the base contour, and when the unlocking handle is in the second position, it is concave relative to the base contour.

[0006] The present invention is further configured such that when the locking handle slides from the first position to the second position, it slides towards the center of the base; when the unlocking handle slides from the first position to the second position, its sliding direction is opposite to that of the locking handle when it slides from the first position to the second position.

[0007] The present invention is further configured such that a front cover is provided on the front of the base, and the front end of the pull rod, the locking handle, and the unlocking handle are located between the front cover and the base.

[0008] The present invention is further configured such that the locking handle and the unlocking handle are arranged at a 180-degree interval in the circumferential direction of the base.

[0009] The present invention is further provided with a connecting cover in front of the front cover, and an outer groove is provided at the joint between the connecting cover and the front cover.

[0010] The present invention is further configured such that the front cover is snapped together with the base; the connecting cover is connected to the base by screws and the front cover is fixed between the two.

[0011] The present invention is further provided that a decorative cover is provided in front of the connecting cover.

[0012] The present invention is further configured such that the decorative cover and the connecting cover are connected by a snap fastener.

[0013] The present invention is further configured such that the front cover and / or the base are provided with a sliding groove, and the locking handle and the unlocking handle slide along the sliding groove; the sliding groove is provided with limiting grooves on both sides, and the locking handle and the unlocking handle are provided with limiting blocks on both sides that are adapted to the limiting grooves.

[0014] The beneficial effects of this utility model are: 1. When the locking handle slides from the first position to the second position, the sliding pin rises from the unlocking part, pulls the suction cup upwards via the inclined part, and reaches the holding part. At this time, both the lever and the sliding pin are under force, resulting in a large friction force when the locking handle slides from the second position to the first position to unlock. This is especially problematic when the locking handle is integrated with the overall contour of the suction cup base for aesthetic reasons, making it difficult to apply force to the locking handle. By setting an unlocking handle, the locking handle is pushed to unlock when it slides from the first position to the second position, forcing the sliding pin to slide back from the holding part to the inclined part. At this time, the force on the locking handle is reduced and the friction is lowered, making it easier to apply force to pull the locking handle back to its first position for complete unlocking. 2. When the locking handle is pressed to perform magnetic locking, the unlocking handle is aligned with the contour of the base. When unlocking is required, press the unlocking handle to make it concave and force the locking handle to pop out. 3. The snap-fit ​​connection between the front cover and the base facilitates the pre-assembly of the locking and unlocking handles; the connection between the connecting cover and the base via screws effectively ensures a secure connection.
