Push-on suction cup structure

The invention relates to a push-type sucker structure, and the technical content relates to the use of a self-holding push-push mechanism to allow a user to operate the sucker with one hand, so that the sucker can achieve stable adsorption and desorption.

The advantages of traditional suction cups are that the installation process is fast, does not damage the surface of the object to be set, and can easily change the suction position. For example, the electronic product bracket installed in the vehicle is sucked on the windshield through the suction cups to facilitate driving. A person clearly views the electronic products mounted on the stand.

In order to ensure that the suction cup can be adsorbed on the object plane for a long time, as shown in the first figure, a common rod assembly is provided above the suction cup. The pressing rod assembly generally includes a stack of lids 2 resting on the suction cup 1, A tie rod 3 provided above the center of the suction cup 1 and passing through the gland 2 and a tie rod 4 provided outside the gland 2 and pivotally connected to the tie rod 3, the pressure rod 4 has an eccentric convex portion 5; When it is placed on the plane of the object and the pressure rod 4 is pressed down, the eccentric convex portion 5 can be pressed against the pressure cover 2 so that the pressure cover 2 is pressed on the periphery of the suction cup 1 and the pull rod 3 is pulled up to generate a negative pressure in the center of the suction cup 1 to stabilize it. Adsorption. On the other hand, the pressure lever 4 can be deflected in the reverse direction to release the pressing cap 2 from pressing the peripheral edge of the sucker 1 to release the suction state of the sucker 1.

Although the lever assembly can ensure that the suction cup can be adsorbed on the object surface for a long time, it needs to hold the cap 2 with one hand and press the lever 4 with the other hand to complete the entire installation process. This operation method is used in the home environment There is not much problem, but it will be particularly inconvenient in a car with a small space. For example, the inclination of the windshield of the car can easily affect the space for operating the pressure lever, or the suction cup falls off during driving and the one-handed Problems with suction cup re-fixing.

Another conventional bulletin number 575104, M512072 provides a structure for pressing the suction cup. The structure, as shown in the second figure, generally includes a stack of gland 2 resting above the suction cup 1, and a position provided above the center of the suction cup 1 and passing through. The push rod 6 of the gland 2, a push button 7 provided on the outside of the gland 2 and interlocking with the push rod 6, and a spring 8 abutting between the gland 2 and the push button 7; when the suction cup 1 is placed on When the push button 7 is pushed down on the plane of the object, the compression spring 8 can be pushed against the push cover 2 so that the push cover 2 presses the periphery of the suction cup 1 and drives the push rod 6 to push down to exhaust the air in the center of the suction cup 1, and then the spring 8 The elastic restoring force is generated to keep the pressing button 7 away from the pressing cover 2 and keep pressing the pressing cover 2 on the periphery of the suction cup 1 to maintain the adsorption force.

However, the spring of 575104 is exposed to the outside, which is prone to the problems of dirt and pinching. The M512072 push button only allows the suction cup to be adsorbed on the plane of the object. To release the suction state of the suction cup, the edge of the suction cup is directly lifted to allow outside air to enter between the suction cup and the plane of the object. The structure is still not perfect.
