Suction cup and vacuum breaking structure

Abstract

This utility model discloses a suction cup and a vacuum-breaking structure, relating to the technical field of vacuum adsorption. The suction cup includes a cup body, a one-way valve, and a sealing plug. The cup body has an air chamber, an air inlet, and an air outlet, both of which are connected to the air chamber. One side of the cup body has an adsorption surface with multiple adsorption holes, which are connected to the air chamber. The air outlet is used to connect to a vacuum generator. The sealing plug includes a plug body and an elastic element, with the plug body connected to the end of the elastic element. The one-way valve evacuates the air outlet, creating a negative pressure environment inside the air chamber, allowing the adsorption surface to adhere to the surface of the object through the adsorption holes. The plug body, under the action of the elastic element, blocks the air inlet, providing a seal and preventing the negative pressure environment inside the air chamber from being disrupted. Applying force to the plug body causes the elastic element to contract and store energy, causing the plug body to detach from the air inlet, allowing positive pressure gas to be introduced into the air chamber to disrupt the negative pressure environment, thus causing the suction cup to detach from the adsorbed object.

Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum adsorption, and specifically relates to a suction cup and a vacuum breaking structure. Background Technology

[0002] Traditional vacuum adsorption methods often require connecting the suction cup to the vacuum source through a pipeline to achieve a continuous adsorption effect. When the suction cup moves or is transferred, the vacuum pipeline cannot be disconnected. This restricts the movement of the suction cup and makes it unsuitable for some special occasions, such as when the vacuum suction cup needs to be flipped or rotated. Utility Model Content

[0003] The purpose of this invention is to provide a suction cup that, when the suction line is disconnected, prevents gas from entering the air chamber through the air outlet, allowing the suction cup to rotate freely while maintaining suction.

[0010] According to the suction cup of this utility model embodiment, the air inlet is located on the side of the cup body away from the suction hole.

[0011] According to the suction cup of this utility model embodiment, a first sealant is provided on one side of the plug body; a stop step is provided on the inner wall of the air inlet, and the sealant abuts against the stop step to seal the air inlet.

[0012] According to an embodiment of the present invention, the suction cup further includes a plug, and the side of the cup body is provided with a plug hole communicating with the air cavity, and the plug is disposed in the plug hole.

[0013] According to an embodiment of the present invention, the suction cup includes a shell and a cover. The shell is provided with a ventilation groove. A sealing step is provided at the opening of the ventilation groove. The edge of the cover abuts against the sealing step, so that the air cavity is formed between the cover and the inner wall of the ventilation groove. A sealing ring is provided on the side of the sealing step facing the cover.

[0014] A vacuum breaking structure provided in a second aspect embodiment of the present invention includes a telescopic drive member, a vacuum breaking member, and a suction cup as described in any of the first aspects embodiments; the telescopic drive member is connected to the vacuum breaking member and drives the vacuum breaking member to extend into the air inlet and squeeze the plug, so that the plug is disengaged from the air inlet.

[0017] According to the vacuum breaking structure of this utility model embodiment, the vacuum breaking structure further includes a support frame and an avoidance driving component, wherein the telescopic driving component is fixed to the support frame; the avoidance driving component is connected to the support frame and is used to drive the support frame to move closer to or away from the suction cup.

[0018] The present invention has at least the following beneficial effects:

[0019] A one-way valve draws air from the vent, creating a negative pressure environment inside the air chamber. Because the pressure inside the suction cup is lower than atmospheric pressure, the suction surface adheres to the object's surface through the suction holes. Since the one-way valve operates from the air chamber to the vent, gas cannot enter the air chamber through the vent when the suction line is disconnected, allowing the suction cup to rotate freely while maintaining suction. The plug, under the action of the elastic element, blocks the inlet, sealing the air chamber and preventing the negative pressure environment inside from being disrupted. Applying force to the plug causes the elastic element to contract and store energy, causing the plug to detach from the inlet, allowing positive pressure gas to enter the air chamber, thus disrupting the negative pressure environment and causing the suction cup to detach from the adsorbed object.

[0036] Reference Figures 1 to 6 The following are several embodiments of the suction cup and vacuum breaking structure of this utility model.

[0037] like Figures 1 to 3As shown, the suction cup of the first aspect embodiment of this utility model includes a disc body 100, a one-way valve 200, and a sealing plug 300. The disc body 100 is provided with an air chamber 130, an air inlet 110, and an air outlet 120, both of which are connected to the air chamber 130. One side of the disc body 100 is provided with an adsorption surface 140, and the adsorption surface 140 is provided with a plurality of adsorption holes 141, which are connected to the air chamber 130. The one-way valve 200 is a suction cup. Valve 200 is disposed at air outlet 120, and the conduction direction of one-way valve 200 is from air chamber 130 to air outlet 120; air outlet 120 is used to communicate with vacuum generator; sealing plug 300 includes plug body 310 and elastic element 320, plug body 310 is connected to the end of elastic element 320; elastic element 320 is disposed on disc body 100, and the elastic force of elastic element 320 causes plug body 310 to block air inlet 110.

[0038] The one-way valve 200 draws air from the vent 120, creating a negative pressure environment inside the air chamber 130. Since the air pressure inside the suction cup is lower than atmospheric pressure, the adsorption surface 140 adheres to the surface of the object through the adsorption hole 141. Because the one-way valve 200 operates from the air chamber 130 to the vent 120, gas cannot enter the air chamber through the vent 120 when the suction line is disconnected, allowing the suction cup to rotate freely while maintaining suction. The plug 310, under the action of the elastic element 320, blocks the inlet 110, providing a seal and preventing the negative pressure environment inside the air chamber 130 from being disrupted. Applying force to the plug 310 causes the elastic element 320 to contract and store energy, causing the plug 310 to detach from the inlet 110. This allows positive pressure gas to be introduced into the air chamber 130, disrupting the negative pressure environment and causing the suction cup to detach from the adsorbed object.

[0039] This embodiment of the invention may include a vacuum generator. A vacuum tube from the vacuum generator is connected to a one-way valve 200 to evacuate the air outlet 120. The one-way valve 200 is oriented from the air chamber 130 to the air outlet 120, ensuring that gas can only flow from the air chamber 130 to the air outlet 120, preventing gas from entering the air chamber 130 through the one-way valve 200. A spring-loaded element 320 is provided to facilitate the reset of the plug 310. Generally, the spring-loaded element 320 is a spring. Applying force to the plug 310 allows the plug to be squeezed through the air nozzle, causing it to disengage from the air inlet 110. Gas is then supplied into the air chamber 130 through the air nozzle to break the negative pressure environment within the air chamber 130, thereby causing the suction cup to detach from the adsorbed item.

[0040] In some embodiments, such as Figure 3As shown, the inner wall of the air cavity 130 is provided with a fixing groove 131, which is used to fix the elastic member 320. The fixing groove 131 and the air inlet 110 are arranged along the extension and retraction direction of the elastic member 320, and the opening of the fixing groove 131 faces the air inlet 110. The elastic element 320 is placed in the fixed groove 131. One end of the elastic element 320 is connected to the bottom of the fixed groove 131 and the other end is connected to the plug 310. When force is applied to the plug 310, the plug 310 moves away from the air inlet 110. The opening of the fixed groove 131 faces the air inlet 110. Under the action of the plug 310, the elastic element 320 is compressed into the fixed groove 131. After the plug 310 is released, since the fixed groove 131 and the air inlet 110 are arranged along the extension and contraction direction of the elastic element 320, the elastic force of the elastic element 320 pushes the plug 310 back into the air inlet 110, thereby sealing the air inlet 110.

[0041] In some embodiments, such as Figure 3 As shown, the suction cup also includes a cover 150, and the plate body 100 is provided with a fixing hole; the cover 150 is located on the outside of the plate body 100 and closes the fixing hole; a fixing groove 131 is formed between the cover 150 and the inner wall of the fixing hole, and the elastic element 320 can be installed by removing the cover 150, which is convenient for later maintenance; the plate body 100 is provided with a groove, the fixing hole is set in the groove, and the cover 150 is set in the groove to prevent the cover 150 from protruding from the surface of the plate body 100; a sealing ring can be set between the cover 150 and the inner wall of the groove to improve the sealing performance of the suction cup.

[0042] In some embodiments, such as Figure 2 and Figure 3 As shown, the air inlet 110 is located on the side of the plate body 100 away from the suction hole 141, which facilitates the vacuum breaking operation of the suction cup through the air inlet 110 when the suction cup is attached to the surface of the object.

[0043] In some embodiments, such as Figure 3 As shown, a first sealant 311 is provided on one side of the plug body 310, and a stop step 160 is provided on the inner wall of the air inlet 110. The plug body 310 abuts against the stop step 160 under the elastic force of the elastic member 320, and the first sealant 311 abuts against the stop step 160 to seal the air inlet 110. The stop step 160 is used to limit the plug body 310 and prevent the plug body 310 from sliding out of the air inlet 110. The first sealant 311 can improve the sealing effect of the plug body 310.

[0044] In some embodiments, such as Figure 3 As shown, the suction cup also includes a plug 170. The side of the cup body 100 is provided with a plug hole that communicates with the air chamber 130. The plug 170 is set in the plug hole to achieve a sealing effect. The effective volume of the air chamber 130 can be appropriately adjusted by the position of the plug 170 in the plug hole. Generally, the plug 170 is a silicone plug 170.

[0045] In some embodiments, such as Figure 1 and Figure 3 As shown, the disk body 100 includes a shell 180 and a cover 190. The shell 180 is provided with a venting groove. The venting groove is used to place the cover 190. A sealing step 181 is provided at the opening of the venting groove. The sealing step 181 fixes the cover 190. The edge of the cover 190 abuts against the sealing step 181, so that an air cavity 130 is formed between the cover 190 and the inner wall of the venting groove. The abutment between the edge of the cover 190 and the sealing step 181 helps to maintain the airtightness of the air cavity 130. The shell 180 and the cover 190 are detachably connected for easy maintenance. The sealing step 181 is provided with a sealing ring on the side facing the cover 190 to improve the sealing effect of the suction cup.

[0046] A vacuum breaking mechanism is provided in the second aspect embodiment of this utility model, such as Figures 4 to 6 As shown, it includes a telescopic drive member 410, a vacuum breaking member 420, and a suction cup of any of the embodiments of the first aspect described above; the telescopic drive member 410 is connected to the vacuum breaking member 420, and drives the vacuum breaking member 420 to extend into the air inlet 110 and squeeze the plug 310, so that the plug 310 is separated from the air inlet 110, thereby breaking the negative pressure state in the air chamber 130, so that the adsorption hole 141 can be separated from the adsorbed object.

[0047] It is understood that if the suction cup has the beneficial effects of the above embodiments, then the vacuum breaking mechanism will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and will not be repeated in this application.

[0048] In some embodiments, such as Figures 4 to 6As shown, an air passage 423 is formed inside the vacuum breaking component 420; a portion of the vacuum breaking component 420 extends into the air inlet 110, squeezing the plug 310 out of the air inlet 110, and by introducing positive pressure gas into the air chamber 130, it accelerates the destruction of the negative pressure environment in the air chamber 130; the vacuum breaking component 420 includes a vacuum breaking component 420, a connecting portion 421 connected to the extension shaft of the telescopic drive component 410, the connecting portion 421 is provided with an abutment surface, the abutment surface is used to abut the end face of the air inlet; the abutment portion 422 protrudes from the abutment surface, and is used to extend into the air inlet 110 and abut against the plug 310, and squeeze out under the drive of the telescopic drive component 410. The plug body 310 is pressed so that it is disengaged from the air inlet 110; a second sealant is provided on the contact surface; the air passage 423 can be connected to the air outlet pipe of the air pump, and the contact part 422 extends into the air inlet 110 to squeeze the plug body 310, and the second sealant on the contact surface seals the periphery of the air inlet, so that the gas in the air passage 423 is input into the air chamber 130 to prevent air leakage; generally, the telescopic drive 410 is a cylinder, and the extension shaft of the cylinder is connected to the connecting part 421; the vacuum breaking part 420 is made of steel to improve the overall strength and wear resistance of the vacuum breaking part 420; the second sealant can be bonded to the contact surface by adhesive.

[0049] In some embodiments, such as Figures 4 to 6 As shown, the abutment portion 422 has an air outlet 120 on one side of its width direction, and the connecting portion 421 has an air inlet 110. The air inlet 110 and the air outlet 120 are connected to the air passage 423. When breaking the vacuum, one end of the abutment portion 422 abuts against the plug body 310 and pushes the plug body 310, so that the air inlet 110 opens and positive pressure gas is introduced into the air chamber 130 through the air outlet 120 to break the negative pressure environment in the air chamber 130. Since the air outlet 120 is located on one side of the abutment portion 422 in its width direction, it is convenient to introduce gas into the air chamber 130 while pushing the plug body 310.

[0050] In some embodiments, such as Figures 4 to 6As shown, the vacuum breaking structure also includes a support frame 430 and a clearance drive component 440. A telescopic drive component 410 is fixed to the support frame 430; the clearance drive component 440 is connected to the support frame 430 and is used to drive the support frame 430 closer to or further away from the suction cup; the telescopic drive component 410 is fixed to the support frame 430, and the vacuum breaking component 420 is connected to the telescopic drive component 410. The clearance drive component 440 drives the support frame 430 closer to or further away, that is, drives the vacuum breaking component 420 closer to or further away from the suction cup; the vacuum breaking component 420 is in the clearance drive component 440... Driven by the suction cup, the contact part 422 of the vacuum breaking component 420 is aligned with the air inlet 110. The telescopic drive component 410 can drive the contact part 422 into the air inlet 110 to input positive pressure gas into the suction cup, thereby realizing the vacuum breaking operation. After the vacuum is broken, the telescopic drive component 410 drives the contact part 422 to be pulled out of the air inlet 110. Driven by the avoidance drive component 440, the vacuum breaking component 420 moves away from the suction cup, so that the vacuum breaking component 420 moves outside the suction cup, so as to avoid the vacuum breaking component 420 from interfering with the normal use of the suction cup.

[0051] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments.
