a suction cup 100;

the connecting seat 200, the connecting seat 200 is connected with the sucking disc 100; the connecting seat 200 is internally provided with a pressure release cavity 210 communicated with the concave cavity of the sucker 100, a mounting hole 220 communicated with the outside and a first pressure release channel 230 communicated with the outside, wherein the mounting hole 220 is communicated with the pressure release cavity 210, and the first pressure release channel 230 is communicated with the mounting hole 220;

the control rod 300 is inserted into the mounting hole 220 and extends into the pressure release cavity 210, the control rod 300 is tightly attached to the mounting hole 220, the control rod 300 can reciprocate along the length direction of the mounting hole 220, and one end of the control rod 300 extending into the pressure release cavity 210 can enable the pressure release cavity 210 to be communicated with the mounting hole 220 along with the movement of the control rod 300, or the pressure release cavity 210 and the mounting hole 220 are isolated from each other.

In practical application, the user can fix the suction cup 100 in two ways:

1. the pressure release cavity 210 and the mounting hole 220 are isolated from each other by the control rod 300, and then the suction cup 100 is pressed to force air in the inner cavity of the suction cup 100 to the outside from the edge of the suction cup 100, so that the suction cup 100 is fixed;

2. the pressure release cavity 210 and the mounting hole 220 are mutually communicated by utilizing the control rod 300, then the suction cup 100 is pressed to force air in the inner cavity of the suction cup 100 to the outside from the pressure release cavity 210, the mounting hole 220 and the first pressure release channel 230 in sequence, and finally the pressure release cavity 210 and the mounting hole 220 are mutually isolated by utilizing the control rod 300, so that the fixation of the suction cup 100 is realized.

And the suction cup 100 is removed by:

1. pressing the control lever 300 causes the pressure release chamber 210 and the mounting hole 220 to communicate with each other, thereby introducing external air into the cavity of the suction cup 100 from the first pressure release passage 230, the mounting hole 220, and the pressure release chamber 210 in this order.

It should be noted that, when the suction cup 100 is fixed, in order to avoid that the pressure release chamber 210 and the mounting hole 220 are mutually communicated to further lose the fixing function of the suction cup 100 due to the pressure of the atmosphere pressing the control lever 300, the control lever 300 may be limited by setting a locking mechanism on the control lever 300;

preferably, the control rod 300 is columnar, the connecting seat 200 is provided with the first groove 240, the control rod 300 is provided with the boss 330, when the pressure release cavity 210 and the mounting hole 220 are required to be isolated, the control rod 300 is pulled out firstly, then the control rod 300 is rotated to enable the boss 330 to be misplaced with the first groove 240, and the boss 330 is blocked by the structure of the connecting seat 200 and cannot be embedded into the first groove 240, so that the control rod 300 is limited, the pressure release cavity 210 and the mounting hole 220 are kept isolated from each other, and the pressure maintaining effect is achieved; when the pressure release cavity 210 and the mounting hole 220 are required to be communicated, the control rod 300 is rotated to align the boss 330 into the first groove 240, the control rod 300 is embedded into the first groove 240 under the action of external force (such as atmospheric pressure and pressure actively pressed by a user), so that the limit of the control rod 300 is released, the pressure release cavity 210 and the mounting hole 220 are communicated with each other, and the pressure release/balance effect of internal and external pressure is achieved.

In certain embodiments, referring to fig. 4, 5, 6 and 7, a recessed section 310 is provided between two ends of the control rod 300 in the length direction, a second pressure release channel 320 is formed between the recessed section 310 and the mounting hole 220, and when the pressure release chamber 210 and the mounting hole 220 are isolated from each other, the second pressure release channel 320 is enclosed in the mounting hole 220 and is communicated with the first pressure release channel 230; when the pressure relief chamber 210 communicates with the mounting hole 220, the pressure relief chamber 210 communicates with the first pressure relief channel 230 through the second pressure relief channel 320.

In this embodiment, the control rod 300 extends into one end of the pressure release cavity 210 to seal the mounting hole 220, so that the pressure release cavity 210 and the mounting hole 220 are isolated from each other, at the moment, the second pressure release channel 320 is only communicated with the first pressure release channel 230, and at most, the air outside can only enter the second pressure release channel 320 but not the concave cavity of the suction cup 100, so that the suction cup 100 can normally maintain pressure to realize fixation; when the control rod 300 is further pressed into the pressure release cavity 210, the second pressure release channel 320 is simultaneously communicated with the pressure release cavity 210 and the first pressure release channel 230, so that external air is introduced into the cavity of the suction cup 100, and the pressure inside and outside the suction cup 100 is balanced, so that the disassembly is realized.

It should be noted that, the concave section 310 may be specifically designed as the second groove; for the columnar control lever 300, a stepped shaft having a smaller diameter than the mounting hole 220 may be designed as the concave section 310.

In some embodiments, referring to fig. 4, 6 and 7, the recessed section 310 is provided with a first seal ring 400 at both ends in the length direction.

According to the embodiment, by arranging the first sealing ring 400, on one hand, when the sucker 100 is fixed, the second pressure release channel 320 and the pressure release cavity 210 can be further ensured to be isolated, on the other hand, the first sealing ring 400 and the mounting hole 220 are in interference fit, and a user can utilize friction force between the first sealing ring 400 and the mounting hole 220 to limit the control rod 300, so that the atmospheric pressure born by the control rod 300 is resisted, the pressure release cavity 210 and the mounting hole 220 are kept isolated from each other, and the pressure maintaining effect is achieved.

In some embodiments, referring to fig. 6 and 7, the mounting hole 220 is provided with a first chamfer at an end near the pressure relief cavity 210, and a second chamfer is provided at an end of the lever 300 extending into the pressure relief cavity 210, the second chamfer being embedded in the first chamfer when the pressure relief cavity 210 and the mounting hole 220 are isolated from each other.

In this embodiment, through setting up first chamfer and the second chamfer of mutually supporting, the chamfer has the guide effect, can be convenient for control rod 300 stretch into the one end of pressure release chamber 210 and accurately aim at the tip of mounting hole 220, ensures that pressure release chamber 210 and mounting hole 220 can normally be isolated.

In certain embodiments, referring to fig. 6 and 7, a second seal is disposed between the first chamfer and the second chamfer to further enhance the isolation of the pressure relief chamber 210 and the mounting hole 220.

In some embodiments, referring to fig. 1 and 2, the hanging fastener 500 is fixedly connected with the connecting seat 200, and the hanging fastener 500 is convenient for a user to fix articles, such as towels, tools, etc., and even cooperates with a plurality of easily detachable sucker fixing pieces to fix plate-type objects, such as a wood plate, a drawing plate, an acrylic plate, etc.
