Description

Technical Field

[0001] This utility model relates to the field of household products technology, specifically to a suction cup and a telescopic rod having the suction cup. Background Technology

[0002] Suction cups are a common household item. After being attached to the wall, they can be used to support and hang items, such as shower curtain rods. Suction cups are attached to both ends of the rod. Shower curtain rods are usually telescopic rods. After the telescopic rod is opened, the suction cups are attached to the wall to hang the shower curtain. However, in order to save costs, existing shower curtain rods do not have suction cups that can achieve vacuum adhesion. Instead, the suction cups are held in place by opening the telescopic rod as much as possible and using the friction between the suction cups and the wall to support the shower curtain. This method of fixing is not secure, and there is a risk that the shower curtain rod will fall. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a suction cup and a telescopic rod having the suction cup, which are in response to the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A suction cup includes a housing with a connector at its upper end and a suction cup base inside the housing. An adsorption disk is located at the bottom of the suction cup base. A guide hole is machined in the center of the suction cup base, and a stretching shaft is disposed within the guide hole. The bottom of the stretching shaft is connected to the adsorption disk. A stretching chamber is provided between the upper part of the suction cup base and the housing. The upper end of the stretching shaft passes through the guide hole and extends into the stretching chamber. A rotating stretching component is disposed within the stretching chamber, fitting around the outside of the stretching shaft. An arc-shaped stretching opening is machined around the periphery of the rotating stretching component. A pin hole is machined at the upper end of the stretching shaft, and a pin is inserted through the pin hole. Both ends of the pin are engaged with the arc-shaped stretching opening. As the rotating stretching component rotates, both ends of the pin move along the shape of the arc-shaped stretching opening, thereby causing the stretching shaft to stretch the adsorption disk and generate vacuum adsorption.

[0006] Furthermore, the suction cup base is provided with connecting posts around its perimeter, and threaded connecting holes are provided inside the connecting posts. Screws are provided on the surface of the outer shell to connect with the threaded connecting holes, thereby fixing the suction cup base to the outer shell.

[0007] Furthermore, the guide hole is an irregularly shaped hole with square holes on the side. The shape of the stretching shaft is adapted to the shape of the guide hole. A connecting plate is provided at the bottom of the stretching shaft. The connecting plate is located in the middle of the adsorption plate. Connecting holes are machined around the periphery of the connecting plate. The adsorption plate is made of rubber. During the forming process of the adsorption plate, the adsorption plate wraps around the connecting plate and passes through the connecting holes.

[0008] Furthermore, the bottom of the suction cup base is provided with a receiving chamber, and the outer diameter of the suction cup is larger than the outer diameter of the suction cup base.

[0009] Furthermore, the arc-shaped stretching opening includes an arc-shaped surface extending from bottom to top, with grooves provided at both ends of the arc-shaped surface.

[0010] Furthermore, the rotating tension member has a connecting seat machined on its side, and the surface of the connecting seat has a mounting groove machined on its surface. A toggle member is provided in the mounting groove, and a positioning post is machined in the middle of the mounting groove. A positioning hole is machined on the toggle member, and the positioning hole of the toggle member is locked onto the positioning post. A screw hole is machined in the positioning post, and the toggle member and the positioning post are locked at the screw hole by a washer and a fixing screw. The side of the outer shell has a toggle groove, and the toggle member extends out of the toggle groove.

[0011] Furthermore, the outer casing surface is provided with clearance holes.

[0012] Furthermore, the connector surface is machined with mounting holes.

[0013] A telescopic rod, with the aforementioned suction cups connected to both ends of the telescopic rod.

[0014] Compared with the prior art, the present invention provides a suction cup and a telescopic rod with the suction cup. After the telescopic rod is extended, it fits tightly against the wall through the suction cup. At the same time, the suction cup is deformed by pushing the actuating element, so that the suction cup is vacuum-adhered to the wall, which greatly improves the support capacity of the telescopic rod.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

Three connecting posts 7 are machined around the suction cup base 3, and threaded connecting holes are machined in the connecting posts 7. Screws are passed through the surface of the housing 1 and connected to the threaded connecting holes to fix the suction cup base 3 to the housing 1.

[0028] The suction cup base 3 has a guide hole 8 in the middle, and a stretching shaft 9 is provided in the guide hole 8. The bottom of the stretching shaft 9 is connected to the adsorption plate 4. In this embodiment, the guide hole 8 is an irregular hole with square holes on both sides. The shape of the stretching shaft 9 is adapted to the shape of the guide hole 8.

A connecting hole 11 is processed around the periphery of the connecting plate 10. The adsorption plate 4 is made of rubber. During the forming process of the adsorption plate 4, the adsorption plate 4 wraps the connecting plate 10 and the material of the adsorption plate 4 itself passes through the connecting hole 11. The adsorption plate 4 and the stretching shaft 9 are connected as a whole.

[0029] A stretching chamber is provided between the suction cup base 3 and the outer shell 1. The upper end of the stretching shaft 9 extends into the stretching chamber through the guide hole 8. A rotating stretching component 11 is provided in the stretching chamber. The rotating stretching component 11 is sleeved on the outside of the stretching shaft 9. An arc-shaped stretching opening 12 is machined around the rotating stretching component 11. A pin hole 13 is machined at the upper end of the stretching shaft 9. A pin 14 is inserted into the pin hole 13. The two ends of the pin 14 are locked on the arc-shaped stretching opening 12. As the rotating stretching component 11 rotates, the two ends of the pin 14 move along the shape of the arc-shaped stretching opening, thereby causing the stretching shaft 9 to stretch the suction cup 4 to generate vacuum adsorption.

[0030] In this embodiment, the arc-shaped stretching opening 12 includes an arc-shaped surface from bottom to top, and a first groove 15 and a second groove 16 are respectively provided at both ends of the arc-shaped surface. Specifically, when both ends of the pin 14 are respectively stuck in the first groove 15, the pin 14 is at the low point of the arc-shaped stretching opening 12, and the adsorption disk is not stretched and deformed at this time. As both ends of the pin 14 move along the shape of the arc-shaped stretching opening, when both ends of the pin 14 are respectively stuck in the second groove 16, the pin 14 is at the high point of the arc-shaped stretching opening 12, and the stretching shaft 9 stretches and deforms the middle of the adsorption disk 4, so that the adsorption disk 4 generates vacuum adsorption.

[0031] The outer diameter of the adsorption disk 4 is larger than the outer diameter of the suction cup base 3. The bottom of the suction cup base 3 is provided with a receiving chamber 17. During the vacuum adsorption process of the adsorption disk 4, the stretching shaft 9 stretches the middle part of the adsorption disk 4 into the receiving chamber 17.

The positioning hole of the toggle member 20 is locked onto the positioning post 21. A screw hole is machined in the positioning post 21. The toggle member 20 and the positioning post 21 are locked at the screw hole by a washer and a fixing screw. An clearance hole 22 is provided on the surface of the outer shell. The washer and the fixing screw can be locked through the clearance hole 22. A toggle groove 23 is machined on the side of the outer shell 1. The toggle member 20 extends out of the toggle groove 23.

[0033] A telescopic rod 24 has suction cups connected to both ends. The telescopic rod 24 is a telescopic rod with an inward retraction. The surface of the connector 2 is machined with mounting holes 25. The end of the telescopic rod 24 is locked in the mounting holes 25 and tightly fitted with the mounting holes. After the telescopic rod 24 is opened, the actuating component 20 is rotated, and the suction cup 4 is stretched and deformed, so that it is vacuum-adsorbed to the wall surface.
