Description

Technical field:

[0001] The utility model relates to the technical field of suction cup products, in particular to a suction cup structure capable of quickly relieving pressure. 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.

[0029] The utility model is further described below in conjunction with specific embodiments and drawings.

[0030] See Figure 2-11 As shown, a suction cup structure that can quickly release pressure includes a suction cup 1 and a connecting seat 2. The lower end of the suction cup 1 has a concave adsorption surface 11, and the upper end of the suction cup 1 is fixed to the lower end of the connecting seat 2. The connecting seat 2 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 11 of the suction cup 1 is docked with the plane of the object, and the suction cup 1 is pressed down to discharge the air between the concave adsorption surface 11 of the suction cup 1 and the plane of the object to form a vacuum, and then the concave adsorption surface 11 and the plane of the object achieve vacuum adsorption positioning, which is the function of a conventional suction cup.

[0031] In order to achieve rapid pressure relief, the utility model has made the following design: the upper end of the suction cup 1 is provided with an air leakage hole 12 which passes through the concave adsorption surface 11, and the connecting seat 2 is provided with a swingable pressure relief lever 3, and a pressing portion 31 is formed at one end of the pressure relief lever 3, and a spring 32 is provided between the lower side of the pressing portion 31 and the connecting seat 2, and a sealing plug 33 which can block the air leakage hole 12 is provided at the lower side of the other end of the pressure relief lever 3, and the pressing portion 31 is pushed upward by the elastic force of the spring 32, and the other end of the pressure relief lever 3 is pressed downward, so that the sealing plug 33 blocks the air leakage hole 12; when the pressing portion 31 is pressed, the other end of the pressure relief lever 3 is tilted upward, and the sealing plug 33 leaves the air leakage hole 12, so that the air leakage hole 12 is connected to the outside. That is to say, under normal conditions, the pressing part 31 of the pressure relief lever 3 is pushed upward by the elastic force of the spring 32, so that the other end of the pressure relief lever 3 is pressed downward, and then the sealing plug 33 blocks the air leakage hole 12. At this time, the suction cup 1 can be used normally. After the concave adsorption surface 11 of the suction cup 1 and the plane of the object are vacuum adsorbed and positioned, when the suction cup 1 needs to be removed relative to the plane of the object, the pressing part 31 of the pressure relief lever 3 is directly pressed to compress the spring. At the same time, the other end of the pressure relief lever 3 is tilted upward, and the sealing plug 33 leaves the air leakage hole 12, so that the air leakage hole 12 is connected to the outside world, achieving the purpose of rapid pressure relief, thereby achieving the purpose of breaking the vacuum, so that the concave adsorption surface 11 of the suction cup 1 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 can also ensure that the purpose of rapid pressure relief can be achieved with one press. Even if the suction cup 1 and the connecting seat 2 are fixedly connected, rapid pressure relief is achieved by pressing the pressing portion 31 of the pressure relief lever 3. The edge of the suction cup 1 does not need to be pulled, so that it will not be limited by the assembly structure of the suction cup 1 and the connecting seat 2, which makes the product design space larger, more convenient to use, and has a wider range of applications. In addition, the structure of the utility model is relatively simple and easy to install.

[0033] The specific assembly structure of the connection seat 2 and the pressure relief lever 3 is as follows: the upper end of the connection seat 2 is provided with a mounting groove 21 penetrating the air relief hole 12, the mounting groove 21 is provided with a first inlay groove 211, the pressure relief lever 3 is installed in the mounting groove 21 in a swingable manner, the lower end of the spring 32 is inlaid in the first inlay groove 211, and the upper end of the spring 32 is inlaid in the second inlay groove 311 provided on the lower end surface of the pressing part 31, so as to ensure that the spring 32 is stably installed between the pressure relief lever 3 and the connection seat 2, so that the spring 32 will not be loose during use, thereby improving the market competitiveness of the product. In addition, the upper end surface of the pressing part 31 also protrudes outside the upper end surface of the connection seat 2, which is easy to be pressed.

The lower end surface of the sealing plug 33 is set as a convex arc surface, and the convex arc surface is embedded in the air relief hole 12, so that the contact area is larger and the sealing effect is better.

[0035] A swing support seat 35 is also fixed in the installation groove 21, and a first lug 351 and a second lug 352 are provided on the swing support seat 35. An axial hole 301 penetrating the two side surfaces is provided in the middle of the pressure relief lever 3. The middle part of the pressure relief lever 3 is arranged between the first lug 351 and the second lug 352, and a fixed shaft 353 is passed between the first lug 351 and the second lug 352 and also passes through the axial hole 301 in the middle part of the pressure relief lever 3, so that the middle part of the pressure relief lever 3 is rotatably connected with the swing support seat 35. The assembly structure is simple, and the stability of the assembly structure can be ensured, and it is also very easy to assemble.

[0036] The connecting seat 2 is fixed to the lower end of a bearing seat 4, and the bearing seat 4 has a hole 41. The upper end of the pressure relief lever 3 extends into the hole 41, and the pressing part 31 of the pressure relief lever 3 also protrudes outside the upper end of the bearing seat 4; the outer periphery of the upper end of the bearing seat 4 is also fixed with a plurality of magnets 5 distributed in a ring shape and used for magnetic attraction and fixation of foreign objects. For example, the foreign object can be an electronic product such as a mobile phone. When in use, the concave adsorption surface 11 of the suction cup 1 can be vacuum adsorbed and positioned with the plane of the refrigerator, so that the utility model is positioned on the refrigerator, and the mobile phone with a mobile phone case with a magnet can be directly placed on the surface of the bearing seat 4, so that the magnet of the mobile phone case is adsorbed and fixed with the magnet 5 on the bearing seat 4, so that the mobile phone can be positioned on the refrigerator to meet different usage requirements. The above is only one way of use. The concave adsorption surface 11 of the suction cup 1 is in contact with the tile surface of the wall to achieve vacuum adsorption positioning. The mobile phone can also be positioned on the tile surface of the wall in the above way. Furthermore, since the pressing portion 31 of the pressure relief lever 3 is also protruding outside the upper end of the supporting seat 4, when the suction cup 1 needs to be removed, the pressing portion 31 of the pressure relief lever 3 can be directly pressed to achieve rapid pressure relief, thereby achieving the purpose of quickly removing the suction cup.

[0037] In order to ensure the stability of the assembly structure of the magnet 5 and the aesthetics of the product, the following design is also made: a cover plate 6 is also provided at the upper end of the supporting seat 4, and the cover plate 6 also covers the magnet 5, and a window 61 is also provided at the position of the cover plate 6 corresponding to the pressing part 31, and the pressing part 31 is exposed in the window 61, and the pressing part 31 can also be conveniently pressed from the outside to drive the pressure relief lever 3 to swing.

[0038] The lower end of the bearing seat 4 is fixed with a base plate 7 by an annular double-sided adhesive tape 71; a damping rotating seat 42 is arranged inside the end of the bearing seat 4, and the end of the base plate 7 is also riveted and fixed to the damping rotating seat 42. The damping rotating shaft 43 passed through the damping rotating seat 42 also extends out of the two sides of the bearing seat 4. A swivel 8 is arranged outside the bearing seat 4, and the two ends of the swivel 8 are respectively fixed to the two ends of the damping rotating shaft 43. The swivel 8 can be hung with foreign objects, and then the foreign objects can be hung through the utility model to meet different usage requirements.

[0039] The end of the bearing seat 4 is also connected to a hanging rope 9 through a pin shaft 91, and the hanging rope 9 can also be hung with external objects, so that the utility model can hang external objects to meet different usage requirements.

[0040] In summary, under normal conditions, the pressing portion 31 of the pressure relief lever 3 is pushed upward by the elastic force of the spring 32, so that the other end of the pressure relief lever 3 is pressed downward, and the sealing plug 33 blocks the air leakage hole 12. At this time, the suction cup 1 can be used normally. After the concave adsorption surface 11 of the suction cup 1 and the plane of the object are vacuum adsorbed and positioned, when the suction cup 1 needs to be removed relative to the plane of the object, the pressing portion 31 of the pressure relief lever 3 is directly pressed to compress the spring. At the same time, the other end of the pressure relief lever 3 is tilted upward, and the sealing plug 33 leaves the air leakage hole 12, so that the air leakage hole 12 is connected to the outside world, achieving the purpose of rapid pressure relief, thereby achieving the purpose of breaking the vacuum, so that the concave adsorption surface 11 of the suction cup 1 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 can also ensure that the purpose of rapid pressure relief can be achieved with one press. Even if the suction cup 1 and the connecting seat 2 are fixedly connected, rapid pressure relief is achieved by pressing the pressing portion 31 of the pressure relief lever 3. The edge of the suction cup 1 does not need to be pulled, so that it will not be limited by the assembly structure of the suction cup 1 and the connecting seat 2, which makes the product design space larger, more convenient to use, and has a wider range of applications.
