Description

Technical field:

[0001] The utility model relates to the technical field of suction cup products, in particular to an improved suction cup structure capable of rapid pressure relief. Background technology:

[0002] Suction cups are mainly used to hang daily objects at any time. Since they can be installed at any position, they are used to hang towels, clothes, etc. Suction cups are easy to use and can be used to keep two objects attached to each other through vacuum and then glued together without drilling into the wall.

[0003] Common suction cups on the market include Figure 1 As shown, the inner side of the suction cup 10 has a concave adsorption surface 101 that contacts the plane of the object and forms vacuum adsorption positioning, and a convex column 102 is provided near the edge of the upper end surface of the suction cup 10. When in use, the concave adsorption surface 101 of the suction cup 10 is docked with the plane of the object, and the suction cup 10 is pressed down to discharge the air between the concave adsorption surface 101 of the suction cup 10 and the plane of the object to form a vacuum, and then the concave adsorption surface 101 and the plane of the object are vacuum adsorbed and positioned. When the suction cup 10 needs to be lifted and detached from the plane of the object, the vacuum needs to be broken to allow air to enter between the concave adsorption surface 101 and the plane of the object so that the suction cup 10 can be detached from the plane of the object. Since a protrusion 102 is provided on the upper end surface of the suction cup 10 near the edge, the protrusion 102 can be pinched and pulled outward by hand, so that the edge of the suction cup 10 can be easily lifted relative to the plane of the object to allow air to enter, thereby breaking the vacuum, so that the suction cup 10 can be lifted and detached from the plane of the object relatively quickly.

[0004] However, since the size of the suction cup is small, the size of the protrusion 102 is even smaller, and it is not convenient for a person to pinch and hold the protrusion 102 and pull it outward, and it often slips off. In addition, a person needs to use a lot of force to pull the protrusion 102 after pinching it, which is not convenient to operate. In addition, when using the suction cup, some corresponding products need to attach the upper end of the suction cup 10 to the lower end of a connecting seat. At this time, there is no position between the connecting seat and the suction cup 10 to accommodate the protrusion 102, resulting in the inability to set the protrusion 102, or, even if the protrusion 102 is set, the connection seat will block the suction cup 10, so that the suction cup 10 cannot be driven by pulling the protrusion 102 outward / upward, and the suction cup 10 cannot be quickly lifted and separated from the plane of the object, causing great trouble to the user.

[0005] In view of this, the inventor proposes the following technical solution. Utility model content:

[0023] The utility model is further described below in conjunction with specific embodiments and drawings.

[0024] See Figure 2-7As shown, an improved suction cup structure capable of rapid pressure relief includes a suction cup 2 and a connecting seat 3. The lower end of the suction cup 2 has a concave adsorption surface 21. The upper end of the suction cup 2 is fixed to the lower end of the connecting seat 3. The connecting seat 3 is used to connect with an external object, so that the utility model can enable the external object to achieve an adsorption function. When in use, the concave adsorption surface 21 of the suction cup 2 is docked with the plane of the object, and the suction cup 2 is pressed down to discharge the air between the concave adsorption surface 21 of the suction cup 2 and the plane of the object to form a vacuum, and then the concave adsorption surface 21 and the plane of the object achieve vacuum adsorption positioning, which is the function of a conventional suction cup.

[0025] The upper end of the suction cup 2 is provided with an air release pipe 22 that can form elastic deformation and an air release hole 23 connecting the air release pipe 22 and the concave adsorption surface 21; the connecting seat 3 is provided with a horizontal sliding channel 301; the push rod 4 is penetrated in the sliding channel 301, and a spring 5 is also provided between the rear end of the push rod 4 and the connecting seat 3; the rear end of the push rod 4 is provided with an opening 41 that passes through the upper and lower end surfaces, and the air release pipe 22 is penetrated in the opening 41, and the push rod 4 moves from the inside to the outside under the elastic force of the spring 5 until the push rod 4 passes through the edge of the opening 41 to flatten the air release pipe 22 to close the inner hole of the air release pipe 22, and the front end of the push rod 4 is exposed outside the connecting seat 3; when the front end of the push rod 4 is pushed to compress the spring 5 to reset the air release pipe 22, the inner hole of the air release pipe 22 is connected with the gap formed between the push rod 4 and the sliding channel 301 to connect with the outside. That is to say, under normal conditions, the push rod 4 will move from the inside to the outside under the elastic force of the spring 5 until the push rod 4 passes through the edge of the opening 41 to flatten the air release tube 22 to close the inner hole of the air release tube 22, and the front end of the push rod 4 is exposed outside the connecting seat 3 so that it can be pushed later. At this time, the air release tube 22 is in a closed state, and the suction cup 1 can be used normally. When the concave adsorption surface 21 of the suction cup 2 and the plane of the object are vacuum-adsorbed and positioned, and when the suction cup 2 needs to be removed relative to the plane of the object in the later stage, the front end of the push rod 4 is directly pushed by hand to After the compression spring 5 is pushed into place, the opening 41 is flush with the air release pipe 22, and the air release pipe 22 automatically resets. At this time, the inner hole of the air release pipe 22 is connected to the gap formed between the push rod 4 and the sliding channel 301 to connect to the outside world, thereby achieving the purpose of rapid pressure relief, thereby achieving the purpose of breaking the vacuum, so that the concave adsorption surface 21 of the suction cup 2 can be easily separated from the plane of the object, and then the suction cup can be quickly removed. It is easy to operate and extremely convenient to use, and does not require a lot of force to press, and it can also ensure that the purpose of rapid pressure relief can be achieved with one push. Even if the suction cup 2 and the connecting seat 3 are fixedly connected, the edge of the suction cup 2 does not need to be pulled to achieve rapid pressure relief by pushing the push rod 4, so that it will not be limited by the assembly structure of the suction cup 2 and the connecting seat 3, so that the product design space is larger, it is more convenient to use, and the scope of application is wider. In addition, the structure of the utility model is relatively simple and it is more convenient to install.

[0026] The connecting seat 3 is provided with through holes 302 distributed in the vertical direction and connected to the sliding channel 301. The vent pipe 22 passes through the through holes 302 to be exposed in the sliding channel 301. Under the action of the spring, the edge of the opening 41 and the edge of the through hole 302 clamp the vent pipe 22 to each other, and then flatten the vent pipe 22 to close the inner hole of the vent pipe 22. Alternatively, the connecting seat 3 is provided with a stopper distributed in the vertical direction. Under the action of the spring, the edge of the opening 41 and the edge of the stopper clamp the vent pipe 22 to each other, and then flatten the vent pipe 22 to close the inner hole of the vent pipe 22. This embodiment is a preferred embodiment, and the ground scheme adopted is: the edge of the opening 41 and the edge of the through hole 302 clamp the vent pipe 22 to each other, and then flatten the vent pipe 22 to close the inner hole of the vent pipe 22.

[0027] The specific structure of the connecting seat 3 is as follows: the connecting seat 3 includes a connecting plate 31 fixed to the upper end of the suction cup 2 and a shell 32 fixed to the upper end of the connecting plate 31, and the sliding channel 301 is arranged between the connecting plate 31 and the shell 32, wherein the connecting plate 31 is provided with a sliding groove 304, and the shell 32 covers the upper end of the sliding channel 301 to form the sliding channel 301, and the sliding channel 301 passes through the outer side of the shell 32 for the push rod to extend. The connecting plate 31 and the connecting plate 31 are fixed as one by a beer injection molding method, and the structure is extremely stable. In addition, the shell 32 and the connecting plate 31 can be fixed by any one or two methods of snap-fitting, ultrasonic fusion, screw locking, and glue bonding, and the installation can be selected according to the actual situation.

[0028] The connecting plate 31 is provided with the through hole 302 .

[0029] In order to make the installation of the spring 5 more stable, a first groove body is set on the side of the push rod 4, and a second groove body is set on the inner wall of the sliding groove 304. The two ends of the spring 5 are respectively inserted into the first groove body and the second groove body, thereby ensuring that the spring 5 is more stably installed between the push rod 4 and the connecting seat 3.

[0030] The shell 32 is also provided with an annular mounting groove 321 on the outside of the connecting plate 31, and a plurality of magnets 6 distributed in an annular shape are provided in the annular mounting groove 321. A cover plate 33 is fixed at the end of the annular mounting groove 321, and the package is encapsulated in the annular mounting groove 321 through the cover plate 33. The utility model can be fixed to an external object by magnetic attraction through the magnet 6. For example, the external object can be an electronic product such as a mobile phone. When in use, the concave adsorption surface 21 of the suction cup 2 can be vacuum adsorbed and positioned with the plane of the refrigerator, so that the utility model can be positioned on the refrigerator. The mobile phone with a mobile phone case with a magnet can be directly placed on the surface of the connecting seat 3, so that the magnet of the mobile phone case is adsorbed and fixed with the magnet 6 in the connecting seat 3, so that the mobile phone can be positioned on the refrigerator to meet different usage requirements. The above is only one usage method; it can also be that the concave adsorption surface 21 of the suction cup 2 is in contact with the tile surface of the wall, so as to achieve vacuum adsorption positioning, and the mobile phone can also be positioned on the tile surface of the wall in the above manner. Since the front end of the push rod 4 is exposed outside the connecting seat 3, it is convenient to be pushed later. After the push rod 4 is pushed inward, the opening 41 is flush with the air release pipe 22, and the air release pipe 22 automatically resets. At this time, the inner hole of the air release pipe 22 is connected to the gap formed between the push rod 4 and the sliding channel 301 to connect to the outside world, thereby achieving the purpose of rapid pressure relief, thereby achieving the purpose of breaking the vacuum, and then achieving the purpose of quickly removing the suction cup.

[0031] A damping rotating seat 34 is riveted and fixed on the cover plate 33. The damping rotating seat 34 is placed in the shell 32, and the damping rotating shaft 341 passing through the damping rotating seat 34 also extends out of both sides of the end of the shell 32. A rotating ring 8 is arranged on the periphery of the shell 32, and the two ends of the rotating ring 8 are respectively fixed to the two ends of the damping rotating shaft 341. The rotating ring 8 can rotate relative to the connecting seat 3, and forms a damped rotation instead of rotating by shaking at will. The rotating ring 8 can be hung with external objects, and then the utility model can hang external objects to meet different usage requirements.

[0032] The outer portion of the housing 32 is provided with a protrusion 303 for easy buckling or pushing.

[0033] To sum up, under normal conditions, the push rod 4 will move from the inside to the outside under the elastic force of the spring 5 until the push rod 4 passes through the edge of the opening 41 to flatten the air release tube 22 to close the inner hole of the air release tube 22, and the front end of the push rod 4 is exposed outside the connecting seat 3 so that it can be pushed later. At this time, the air release tube 22 is in a closed state, and the suction cup 1 can be used normally; when the concave adsorption surface 21 of the suction cup 2 and the plane of the object are vacuum-adsorbed and positioned, and when the suction cup 2 needs to be removed relative to the plane of the object in the later stage, the front end of the push rod 4 is directly pushed by hand to After the compression spring 5 is pushed into place, the opening 41 is flush with the air release pipe 22, and the air release pipe 22 automatically resets. At this time, the inner hole of the air release pipe 22 is connected to the gap formed between the push rod 4 and the sliding channel 301 to connect to the outside world, thereby achieving the purpose of rapid pressure relief, thereby achieving the purpose of breaking the vacuum, so that the concave adsorption surface 21 of the suction cup 2 can be easily separated from the plane of the object, and then the suction cup can be quickly removed. It is easy to operate and extremely convenient to use, and does not require a lot of force to press, and it can also ensure that the purpose of rapid pressure relief can be achieved with one push. Even if the suction cup 2 and the connecting seat 3 are fixedly connected, the edge of the suction cup 2 does not need to be pulled to achieve rapid pressure relief by pushing the push rod 4, so that it will not be limited by the assembly structure of the suction cup 2 and the connecting seat 3, so that the product design space is larger, it is more convenient to use, and the scope of application is wider.
