Description

Technical Field

[0001] This utility model belongs to the field of adsorption support technology, and particularly relates to a negative pressure adsorption support. Background Technology

[0002] Negative pressure adsorption technology, which can achieve "non-destructive fixation", has been widely used in home storage (such as vacuum hooks), automotive electronics (such as mobile phone magnetic holders), equipment maintenance (such as parts fixation) and outdoor camping (such as lamp adsorption) and other scenarios.

[0003] Existing negative pressure adsorption supports are mainly divided into two types based on their power source: electrically controlled and simple mechanical. However, both types of solutions have insurmountable technical defects in practical applications and cannot meet the comprehensive needs of non-electrical compatibility, installation in confined spaces, convenient disassembly and removal, and stable adsorption.

[0004] For electrically controlled negative pressure adsorption supports, an internal power supply is required. This not only increases the overall size of the support and requires a certain amount of installation space, but also leads to the phenomenon of power failure and inability to adsorb, which seriously affects the user experience. For simple mechanical adsorption supports, the core is to create negative pressure by pressing to expel air from the suction cup and thus adsorb objects. However, it cannot effectively prevent air backflow, the negative pressure is maintained for a short time, the adsorption stability is poor, and the negative pressure must be broken by prying the edge of the suction cup or pulling the adsorbed object when disassembling. This can easily cause wear and tear on its own structure, thus affecting its service life.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a negative pressure adsorption support to overcome the shortcomings in current practical applications. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a negative pressure adsorption support to solve the problems in the background technology mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A negative pressure adsorption support includes a support body, a mounting bracket rotatably mounted on one outer wall of the support body, a cover plate one mounted on the other side of the support body, a cover plate two fixed to the inner side of the cover plate one, the cover plate two being located inside the support body, and the cover plate two and the middle part of the support body forming a negative pressure cavity, and further includes:

[0009] The negative pressure adsorption mechanism includes a pressing component, a silicone suction cup, and a negative pressure one-way valve. One end of the pressing component is located in the negative pressure cavity and connected to the second cover plate. The side wall of the pressing component is in contact with the inner wall of the negative pressure cavity. The other end of the pressing component extends to the outside of the main body. The silicone suction cup is fixed to the bottom of the first cover plate. The negative pressure one-way valve is installed in the middle of the second cover plate. One end of the negative pressure one-way valve is connected to the negative pressure cavity. The other end of the negative pressure one-way valve corresponds to the through hole opened in the middle of the first cover plate, and the through hole is connected to the silicone suction cup.

[0010] The venting mechanism has one end fixed to the cover plate 2 and passing through the cover plate 1 to connect with the silicone suction cup, and the other end of the venting mechanism is slidably installed on the side wall of the support body.

[0011] As a further technical solution of this utility model, the pressing assembly includes a piston column, a piston silicone ring and a negative pressure spring. One end of the piston column is located in the negative pressure cavity. A piston silicone ring that fits against the inner wall of the negative pressure cavity is fixed on the side wall of the piston column. One end of the piston column is connected to the middle of the cover plate two through the negative pressure spring. The other end of the piston column extends to the outside of the support body.

[0012] As a further technical solution of this utility model, the venting mechanism includes a venting button, a venting one-way valve, and a venting channel. The venting button is horizontally slidably installed on the side wall of the support body. One end of the venting button is connected to one end of the venting one-way valve, and the venting channel is connected to the other end of the venting one-way valve. One end of the venting channel passes through the second cover plate, the first cover plate, and the silicone suction cup in sequence and is connected to the negative pressure space inside the silicone suction cup.

[0013] As a further technical solution of this utility model, a venting spring is installed between the venting button and the venting check valve. The venting spring is used to reset the venting button and the venting check valve when they are in a non-contact state.

[0014] As a further technical solution of this utility model, a sealing ring is installed between the second cover plate and the first cover plate. The sealing ring is located outside the through hole and the negative pressure one-way valve, and the sealing ring is used to seal the connection between the silicone suction cup, the negative pressure one-way valve and the through hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Initially, the pressing component moves to the top of the negative pressure chamber using its own elastic force. At this time, the pressure inside the negative pressure chamber is normal, and the venting mechanism is not working. When the object being adsorbed comes into full contact with the silicone suction cup, the pressing component moves down inside the negative pressure chamber, causing the chamber to be in a negative pressure state. The negative pressure chamber in this state can draw air from the silicone suction cup through the negative pressure one-way valve, creating a negative pressure state between the silicone suction cup and the object being adsorbed. This allows for rapid adsorption of the object. Compared to the traditional negative pressure adsorption method using a motor and solenoid valve, the pressing adsorption method, consisting of the pressing component, negative pressure chamber, and negative pressure one-way valve, requires no external power supply and can be used normally in power-free environments. This solves the problem of electric adsorption failing when power is off, reduces the production cost of the support, and improves its flexibility and convenience. Furthermore, this method can reduce the overall size of the support, making it easier to install in confined spaces and improving its applicability.

[0017] When it is necessary to remove the adsorbed object, press the degassing mechanism with one hand to connect the degassing mechanism with the negative pressure space formed between the silicone suction cup and the adsorbed object. This allows outside air to enter the negative pressure space, changing the pressure of the negative pressure space and enabling the adsorbed object to be removed quickly.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 4 As shown, a negative pressure adsorption support provided as an embodiment of this utility model includes a support body 1, an mounting bracket 2 rotatably mounted on one outer wall of the support body 1, a cover plate 6 mounted on the other side of the support body 1, a cover plate 7 fixed inside the cover plate 6, the cover plate 7 being located inside the support body 1, and the cover plate 7 and the middle part of the support body 1 forming a negative pressure cavity 10, and further includes:

[0027] The negative pressure adsorption mechanism includes a pressing component 3, a silicone suction cup 4, and a negative pressure one-way valve 8. One end of the pressing component 3 is located inside the negative pressure cavity 10 and is connected to the cover plate 7. The side wall of one end of the pressing component 3 is in contact with the inner wall of the negative pressure cavity 10. The other end of the pressing component 3 extends to the outside of the main body. The silicone suction cup 4 is fixed to the bottom of the cover plate 6. The negative pressure one-way valve 8 is installed in the middle of the cover plate 7. One end of the negative pressure one-way valve 8 is connected to the negative pressure cavity 10. The other end of the negative pressure one-way valve 8 corresponds to the through hole opened in the middle of the cover plate 6, and the through hole is connected to the silicone suction cup 4.

[0028] The venting mechanism 5 has one end fixed to the cover plate 7 and passes through the cover plate 6 to communicate with the silicone suction cup 4. The other end of the venting mechanism 5 is slidably installed on the side wall of the support body 1.

[0029] Initially, the pressing component 3 moves to the top of the negative pressure chamber 10 using its own elastic force. At this time, the pressure inside the negative pressure chamber 10 is at normal, and the venting mechanism 5 is not in operation. After the object being adsorbed comes into full contact with the silicone suction cup 4, the pressing component 3 moves downward within the negative pressure chamber 10, causing the chamber to be in a negative pressure state. In this negative pressure state, the negative pressure chamber 10 can use the negative pressure one-way valve 8 to draw air from the silicone suction cup 4, thus creating a negative pressure state between the silicone suction cup 4 and the object being adsorbed. This allows for rapid adsorption of objects. Compared to the traditional negative pressure adsorption method using a motor and solenoid valve, the press adsorption method, consisting of the press assembly 3, negative pressure chamber 10, and negative pressure one-way valve 8, requires no external power supply and can be used normally in power-free environments. This solves the problem of electric adsorption failing when power is off, reduces the production cost of the support, and improves the flexibility and convenience of the support. Furthermore, this method can reduce the overall size of the support, making it easier to install in confined spaces and improving the applicability of the support.

[0030] When it is necessary to remove the adsorbed object, press the degassing mechanism 5 with one hand to connect the degassing mechanism 5 with the negative pressure space formed between the silicone suction cup 4 and the adsorbed object. This allows outside air to enter the negative pressure space, changing the pressure of the negative pressure space and enabling the adsorbed object to be removed quickly.

[0031] The negative pressure one-way valve 8 can only allow air to enter the negative pressure chamber 10 from the negative pressure space, but the gas in the negative pressure chamber 10 cannot enter the negative pressure space through the negative pressure one-way valve 8.

[0032] like Figures 1 to 4 As shown, in a preferred embodiment of the present invention, the pressing assembly 3 includes a piston column 31, a piston silicone ring 32, and a negative pressure spring 33. One end of the piston column 31 is located inside the negative pressure cavity 10. The piston silicone ring 32, which is in contact with the inner wall of the negative pressure cavity 10, is fixed on the side wall of the piston column 31. One end of the piston column 31 is connected to the middle of the cover plate 7 through the negative pressure spring 33. The other end of the piston column 31 extends to the outside of the support body 1.

[0033] Once the object being adsorbed is in full contact with the silicone suction cup 4, manually press the piston column 31. This causes the space between the bottom of the piston column 31 and the cover plate 7 to continuously shrink, creating a negative pressure chamber 10. The negative pressure chamber 10, under negative pressure, can use the negative pressure one-way valve 8 to draw air from the silicone suction cup 4, thus creating a negative pressure state between the silicone suction cup 4 and the object being adsorbed. This allows for rapid adsorption of the object without any external power source, enabling normal operation in situations without electricity. This solves the problem of electric adsorption failing upon power failure, reduces the production cost of the support, and improves its flexibility and convenience. Furthermore, this method reduces the overall size of the support, making it easier to install in confined spaces and enhancing its applicability.

[0034] When the negative pressure check valve 8 is removed, the negative pressure chamber 10 is directly connected to the silicone suction cup 4. This support can also effectively adsorb objects. First, the piston column 31 is pressed, so that the negative pressure spring 33 is in a compressed state. The space between the bottom of the piston column 31 and the cover plate 7 is continuously reduced. The air in this space is discharged by the silicone suction cup 4. At this time, the adsorbed object is effectively attached to the silicone suction cup 4, and the piston column 31 is released, so that the negative pressure spring 33 drives the piston column 31 to move back through its own elastic force, thereby changing the size of the space between the bottom of the piston column 31 and the cover plate 7, so that the negative pressure chamber 10 is in a negative pressure state, thereby completing the effective adsorption of the adsorbed object.

[0035] The piston silicone ring 32 is preferably a ring structure with a U-shaped cross-section and a stepped end face that fits into the negative pressure cavity 10.

[0036] like Figures 1 to 4 Therefore, in a preferred embodiment of this utility model, the venting mechanism 5 includes a venting button 51, a venting one-way valve 52, and a venting channel 53. The venting button 51 is horizontally slidably mounted on the side wall of the support body 1. One end of the venting button 51 is connected to one end of the venting one-way valve 52. The venting channel 53 is connected to the other end of the venting one-way valve 52. One end of the venting channel 53 passes through the second cover plate 7, the first cover plate 6, and the silicone suction cup 4 in sequence and is connected to the negative pressure space inside the silicone suction cup 4.

[0037] Initially, the venting one-way valve 52 is closed. When it is necessary to remove the adsorbed object, the venting button 51 is pressed with one hand, which opens the venting one-way valve 52, thereby connecting it with the negative pressure space formed between the silicone suction cup 4 and the adsorbed object. This allows outside air to enter the negative pressure space through the venting one-way valve 52 and the venting channel 53, changing the pressure of the negative pressure space and releasing the adsorption state of the silicone suction cup 4 on the adsorbed object, so that the adsorbed object can be quickly removed. Moreover, the venting one-way valve 52 can only deliver outside air into the venting channel 53, while the gas in the negative pressure space cannot leak into the outside environment through the venting one-way valve 52, ensuring the airtightness of the negative pressure space when adsorbing the adsorbed object.

[0038] A venting spring is installed between the venting button 51 and the venting check valve 52. The venting spring is used to reset the venting button 51 and the venting check valve 52 when they are not in contact, thereby ensuring the negative pressure seal between the silicone and the adsorbed object.

[0039] like Figures 2 to 4 As shown, in a preferred embodiment of this utility model, a sealing ring 9 is installed between the second cover plate 7 and the first cover plate 6. The sealing ring 9 is located outside the through hole and the negative pressure one-way valve 8, and the sealing ring 9 is used to seal the connection between the silicone suction cup 4, the negative pressure one-way valve 8 and the through hole, thereby improving the overall sealing performance of the support.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
