Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, specifically a suction cup. Background Technology

[0002] Suction cup devices can adhere to smooth glass and tile walls for hanging items, and are widely used in kitchens and bathrooms. Some existing suction cup structures primarily use a rotating mechanism. For example, the suction cup is first attached to the object to be suctioned, and then the rotating part is twisted, causing the center of the suction cup to move away from the object, creating a negative pressure space to fix the suction cup in place. This method requires multiple fingers or even the entire palm to rotate simultaneously, which can easily lead to slippage during use. Therefore, there is a need to design a suction cup that only requires two fingers to pinch and adhere, thus solving the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a suction cup to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is: a suction cup, including a base and a hook portion disposed on one side of the base, a suction cup assembly slidably inserted inside the bottom end of the base, a stop ring with a diameter smaller than that of the suction cup assembly fixed at the bottom end of the base, a sliding groove seat installed on the top of the base, a lifting member for lifting the suction cup assembly slidably installed in the sliding groove seat, a convex shaft that cooperates with the lifting member in a lifting transmission is fixed at the top end of the suction cup assembly, and a sliding cover is connected to the top end of the lifting member.

[0005] The effect achieved by the above components is as follows: By setting up a base, suction cup assembly, lifting component, and sliding cover, when two fingers pinch the sliding cover and the base, the sliding cover drives the lifting component to slide along the sliding groove seat. The convex shaft and the lifting component cooperate to convert the horizontal movement into vertical movement, thereby lifting the suction cup assembly and cooperating with the stop ring to form a negative pressure space between it and the object being adsorbed. The stop ring restricts excessive deformation of the suction cup assembly, ensuring edge sealing during adsorption and achieving the purpose of rapid adsorption. This design only requires two fingers to pinch, solving the problem that existing rotary suction cups require multiple fingers or even the entire palm to rotate and exert force simultaneously, and are prone to slipping, thus achieving the purpose of simple operation and labor saving.

[0006] Preferably, the lifting component includes a slider slidably mounted in the slide seat, the slider having a guide slope, the top of the guide slope having a first groove, the guide slope having a sliding hole extending to the bottom of the slider, the top of the suction cup assembly being slidably inserted into the sliding hole, the bottom of the guide slope having a second groove, and the inner side of the bottom of the sliding cover being connected to the slider.

[0007] The effect achieved by the above components is as follows: before the pinching action, the convex shaft slides along the guide slope. In the initial state, when the convex shaft is located in the second groove, the suction cup assembly initially adheres to the surface to be absorbed. When the pinching action is performed, the convex shaft slides upward along the guide slope to the first groove, and the suction cup assembly is lifted to the maximum extent to form a stable negative pressure.

[0008] Preferably, a ramp block is fixed at the top of the slider near the bottom of the guide ramp.

[0009] The effect achieved by the above components is that the inclined block at the top of the slider acts as a limit and buffer when the slider is driven to slide by the sliding cover, preventing the slider from sliding excessively, protecting the structural integrity of the suction cup assembly, and extending its service life.

[0010] Preferably, a limiting block that fits against the top of the suction cup assembly is fixed inside the slide seat near the end of the slide hole.

[0011] The effect achieved by the above components is that the limiting block can guide and support the suction cup assembly in the vertical direction, and can also provide auxiliary support on its side to prevent damage to the connection between the top structure of the suction cup assembly and the convex shaft under the pinching action.

[0012] Preferably, one end of the slide seat is provided with an opening, and both sides of the top of the slide seat are provided with protrusions that slide and limit the movement of the slider side.

[0013] The effects achieved by the above components are as follows: the opening at one end of the slide seat facilitates the installation and disassembly of the lifting component, and the protrusions on both sides of the top end slide and limit the sliding of the slider side, making the slider slide more smoothly in the slide seat and improving the smoothness of the adsorption operation.

[0014] Preferably, the inner side of the bottom end of the sliding cover is fixed with a connecting part sleeved on the outside of the slider. The connecting part includes a convex ring connected to the sliding cover. Both ends of the convex ring are equipped with elastically expandable claws. The convex ring is sleeved on the outside of the slider, and both ends of the slider are provided with a groove for engaging with the claws.

[0015] The effect achieved by the above components is as follows: the connecting part at the bottom of the sliding cover is sleeved on the outside of the slider through a convex ring, and the claw engages with the slots at both ends of the slider, realizing the detachable connection between the sliding cover and the slider. This connection method not only facilitates the assembly and maintenance of the suction cup, but also ensures the connection stability between the sliding cover and the slider, enabling the two to move synchronously and ensuring the normal operation of the suction cup.

[0016] Preferably, the suction cup assembly includes a suction cup located below the base, with a connecting rod connected to the top of the suction cup. The top of the connecting rod passes through the base and extends into the slider and fits against the inner wall of the sliding hole. The convex shaft is slidably inserted into the top of the connecting rod.

[0017] The above components achieve the following effect: the connecting rod can lift the center of the suction cup under the lifting action of the convex shaft, and with the help of the stop ring, it can perform negative pressure adsorption.

[0018] Preferably, the top end of the connecting rod is provided with a semi-circular chamfer.

[0019] The effect achieved by the above components is that the semi-circular chamfer reduces the frictional damping between the top of the connecting rod and the inclined block, making it easier and less strenuous for the connecting rod to pull up the suction cup.

[0020] This utility model provides a suction cup with the following improvements and advantages compared with the prior art:

[0021] This invention allows the sliding cover to slide along the slide groove when the sliding cover is pinched between two fingers and the base. The convex shaft and the lifting component work together to convert the horizontal motion into vertical motion, thereby lifting the suction cup assembly and creating a negative pressure space between it and the object being suctioned, in conjunction with the stop ring. The stop ring restricts excessive deformation of the suction cup assembly, ensuring edge sealing during suction and achieving rapid suction. This design only requires two fingers to pinch, solving the problem of existing rotary suction cups requiring multiple fingers or even the entire palm to rotate simultaneously and easily slipping, thus achieving the purpose of simple and labor-saving operation.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0030] This utility model provides an improved suction cup. The technical solution of this utility model is as follows:

[0031] In embodiments of this utility model, such as Figures 1-4As shown, a suction cup includes a base 1 and a hook portion 3 disposed on one side of the base 1. A suction cup assembly 8 is slidably inserted into the bottom end of the base 1. The suction cup assembly 8 includes a suction cup 81 located below the base 1. A connecting rod 82 is connected to the top of the suction cup 81. The top of the connecting rod 82 passes through the base 1 and extends into the slider 61 and fits against the inner wall of the sliding hole 63. A convex shaft 7 is slidably inserted into the top of the connecting rod 82. The connecting rod 81 can lift the center of the suction cup 82 under the lifting action of the convex shaft 7. With the help of the stop ring 10, negative pressure adsorption can be performed. A stop ring 10 with a diameter smaller than that of the suction cup assembly 8 is fixed at the bottom end of the base 1. A sliding groove seat is installed on the top of the base 1. 5. One end of the slide base 5 is provided with an opening, and the top two sides of the slide base 5 are provided with protrusions that slide and limit the slider 61. The opening at one end of the slide base 5 facilitates the installation and removal of the lifting component 6. The protrusions on both sides of the top end slide and limit the slider 61, making the slider 61 slide more smoothly in the slide base 5. The lifting component 6 for lifting the suction cup assembly 8 is slidably installed in the slide base 5. The lifting component 6 includes a slider 61 slidably installed in the slide base 5. The slider 61 is provided with a guide slope 62. The top end of the guide slope 62 is provided with a first groove 64. The guide slope 62 is provided with a sliding hole 63 extending to the bottom end of the slider 61. The suction cup assembly 8 The top end slides into the sliding hole 63. A second groove 65 is provided at the bottom end of the guide slope 62. The inner side of the bottom end of the sliding cover 2 is connected to the slider 61. Before the pinching action, the convex shaft 7 slides along the guide slope 62. In the initial state, when the convex shaft 7 is located in the second groove 65, the suction cup assembly 8 initially adheres to the surface to be absorbed. When the pinching action is performed, the convex shaft 7 slides upward along the guide slope 62 to the first groove 64, at which point the suction cup assembly 8 is lifted to the maximum extent, forming a stable negative pressure. The top end of the suction cup assembly 8 is fixed with a convex shaft 7 that cooperates with the lifting member 6 for lifting transmission. The top end of the lifting member 6 is connected to the sliding cover 2. The inner side of the bottom end of the sliding cover 2 is fixed with a sleeve on the slider 61. The external connecting part 4 includes a protruding ring 41 connected to the sliding cover 2. The protruding ring 41 has elastically expandable claws 42 installed at both ends. The protruding ring 41 is sleeved on the outside of the slider 61, and both ends of the slider 61 are provided with slots 9 that engage with the claws 42. The connecting part 4 at the bottom of the sliding cover 2 is sleeved on the outside of the slider 61 through the protruding ring 41. The claws 42 engage with the slots 9 at both ends of the slider 61, realizing the detachable connection between the sliding cover 2 and the slider 61. This connection method not only facilitates the assembly and maintenance of the suction cup, but also ensures the connection stability between the sliding cover 2 and the slider 61, enabling the two to move synchronously and ensuring the normal operation of the suction cup.

[0032] In an embodiment of this utility model, a limiting block 11 is fixed in the sliding groove seat 5 near the end of the sliding hole 63, which is in contact with the top of the suction cup assembly 8. The limiting block 11 can guide and support the suction cup assembly 8 in the vertical direction, and can also provide auxiliary support to its side, so as to prevent damage to the connection between the top structure of the suction cup assembly 8 and the convex shaft 7 under the pinching action.

[0033] In this embodiment of the utility model, a ramp block 66 is fixed at the top of the slider 61 near the bottom of the guide ramp 62. The ramp block 66 at the top of the slider 61 plays a limiting and buffering role when the slider 61 is slid by the sliding cover 2, preventing the slider 61 from sliding excessively and protecting the structural integrity of the suction cup assembly 8. The top of the connecting rod 82 is provided with a semi-circular chamfer. The semi-circular chamfer can reduce the frictional damping between the top of the connecting rod 82 and the ramp block 66, making it easier and less strenuous for the connecting rod 81 to pull up the suction cup 82.

[0034] The working principle of the suction cup provided by this utility model is as follows: First, the suction cup 82 is attached to the object to be adsorbed. At this time, it is in the initial state, where the convex shaft 7 is located in the second groove 65. The suction cup assembly 8 initially adheres to the surface to be adsorbed. When the pinching action is performed, the convex shaft 7 slides upward relative to the first groove 64 along the guide inclined surface 62, converting the horizontal movement into vertical movement. The connecting rod 81 pulls the suction cup 82 to the maximum amplitude, and the stop ring 10 restricts the excessive deformation of the suction cup 82 to ensure edge sealing during adsorption and achieve the purpose of rapid adsorption action.
