Description

Technical Field

[0001] This disclosure relates to the field of suspension fixing device technology, and in particular to a dual suction cup integrated suspension fixing device. Background Technology

[0002] With the fast pace of modern life and increasing demands for space utilization, hanging storage and fixing devices have become an important means of improving space efficiency. Traditional hanging fixing devices, such as single-channel suction cups or nail-free strong adhesive, have many problems. Single-channel suction cups are prone to rotation or displacement when fixing large items. While using dual suction cups can improve the stability of suspended objects, the two suction cups have poor coordination and need to be fixed separately for use. Nail-free strong adhesive is difficult to adjust once fixed, and these limitations restrict its diversified applications. In addition, existing suction cups generate adsorption force by pulling and lifting the center point, which is unstable in the environment of air changes or thermal expansion and contraction, and is also prone to aging and falling off. Utility Model Content

[0003] This disclosure provides a dual-suction cup integrated suspension fixing device to at least solve the above-mentioned technical problems existing in the prior art.

[0004] The dual-suction cup integrated suspension fixing device according to this disclosure includes:

[0005] The fixed base is provided with an adsorption surface that contacts the surface to be installed and multiple piston chambers;

[0006] A first colloid coating part is disposed below the piston cavity and connected to the fixed base, and the edge of the first colloid coating part communicates with the piston cavity to form an air intake hole;

[0007] A piston assembly includes a piston element and a one-way valve structure. The piston element is movably disposed within a piston chamber and has an exhaust port. The one-way valve structure is connected to the piston element and is used to open or close the exhaust port.

[0008] The housing is connected to multiple piston components and is used to simultaneously press the multiple piston components to perform an exhaust operation under the action of external force.

[0009] In one embodiment, the piston member is further provided with a receiving cavity, the exhaust port is formed at the bottom of the receiving cavity, and the one-way valve structure is disposed in the receiving cavity.

[0010] In one embodiment, the one-way valve structure includes a one-way valve piston, a fixed cover, and an elastic element. The fixed cover is fixed in the accommodating cavity, and the one-way valve piston is movably disposed on the fixed cover. One end of the elastic element abuts against the one-way valve piston, and the other end abuts against the fixed cover, for pushing the one-way valve piston to close the exhaust port.

[0011] In one embodiment, the one-way valve structure further includes a one-way valve seal, which is disposed at the connection between the one-way valve piston and the exhaust port.

[0012] In one embodiment, the piston assembly further includes a negative pressure spring, one end of which abuts against the first colloid coating portion and the other end of which abuts against the piston member; wherein the piston member has a first position away from the first colloid coating portion and a second position close to the first colloid coating portion within the piston cavity, and the negative pressure spring has an initial state and a contracted state; when the piston member is in the first position, the negative pressure spring is in the initial state; when the piston member is in the second position, the negative pressure spring is in the contracted state.

[0013] In one embodiment, the piston assembly further includes a piston seal disposed on the outer periphery of the piston assembly and engaging with the inner wall of the piston cavity.

[0014] In one embodiment, the first colloid coating portion includes a base plate and a mesh structure disposed on the surface of the base plate.

[0015] In one embodiment, a second colloidal coating portion is formed on the surface of the adsorption surface, the first colloidal coating portion is provided with a first colloidal layer, the second colloidal coating portion is provided with a second colloidal layer, and the first colloidal layer and the second colloidal layer are coplanar with the adsorption surface.

[0016] In one embodiment, a fixing member is further included, which is fixedly connected to the fixed base, and the fixing member is used to fix the object to be suspended.

[0017] In one embodiment, the fixed base is further provided with a locking hole for inserting a locking member to securely connect the locking member to the surface to be installed.

[0018] In this disclosure, the dual-suction cup integrated suspension fixing device increases the number of points of adsorption force through the design of multiple piston chambers and piston assemblies, enabling the dual-suction cup integrated suspension fixing device to be more firmly adsorbed onto the surface to be installed. This effectively avoids the problem of overall detachment caused by the failure of a single adsorption point and improves the stability of adsorption. Combining adsorption and colloid fixing methods, when the adsorption force is sufficient, fixation is achieved through adsorption. When the adsorption force is insufficient or a more secure fixation is required, the first colloid coating can be used to further enhance the fixing effect, meeting the requirements of different usage scenarios and the characteristics of the surface to be installed. Furthermore, the housing is connected to multiple piston components, allowing users to simultaneously vent multiple piston components by pressing the housing, eliminating the need to operate each piston individually. This significantly improves installation efficiency and makes the dual-suction cup integrated suspension fixing device more convenient and faster to use. When the installation position needs to be changed, due to the reversibility of the suction fixing method, the dual-suction cup integrated suspension fixing device can be easily removed by simply breaking the negative pressure, without leaving any obvious marks on the installation surface. Additionally, if the adhesive fixing part uses removable glue, the position can be changed without damaging the installation surface, enabling the dual-suction cup integrated suspension fixing device to be reused and reducing usage costs.

[0034] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0035] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0036] Reference Figures 1-4 As shown, this disclosure discloses an exemplary embodiment of a dual-suction cup integrated suspension fixing device, including a fixed base 1, a first colloid coating part 2, a piston assembly 3, and a housing 4. The fixed base 1 is provided with an adsorption surface 11 that contacts the surface to be installed and multiple piston chambers 12. The first colloid coating part 2 is disposed below the piston chambers 12 and connected to the fixed base 1, with its edge communicating with the piston chambers 12 to form an air intake hole 13. The piston assembly 3 includes a piston element 31 and a one-way valve structure 32. The piston element 31 is movably disposed within the piston chambers 12 and has an exhaust hole 311. The one-way valve structure 32 is connected to the piston element 31 and is used to open or close the exhaust hole 311. The housing 4 is connected to multiple piston elements 31 and is used to simultaneously press multiple piston elements 31 under external force to perform an exhaust operation.

[0037] In this embodiment, the fixed base 1 is the basic support part of the entire dual-suction cup integrated suspension fixing device. The adsorption surface 11 can fit tightly with the surface to be installed, providing a foundation for subsequent adsorption and fixing. The arrangement of multiple piston chambers 12 can increase the points of application of adsorption force and improve the overall adsorption stability. It can be understood that the number of piston chambers 12 can be two or more, and can be adapted to the needs of practical applications. The number of the first colloid coating part 2 and the piston assembly 3 is the same as the number of piston chambers 12, and is arranged corresponding to the piston chambers 12. In the embodiments shown in this disclosure, the number of piston chambers 12 and piston assembly 3 is two. The first colloid coating part 2 can be coated with a first colloid, such as nail-free strong adhesive. When the adsorption force is insufficient, the first colloid can further enhance the connection force between the dual-suction cup integrated suspension fixing device and the surface to be installed. The first colloidal coating part 2 can be integrally formed with the fixed base 1. The suction hole 13 is designed to be formed at the edge of the first colloidal coating part 2 and is connected to the piston chamber 12. This design facilitates the discharge of air from the piston chamber 12 when the piston assembly 3 is pressed, thereby creating a negative pressure and achieving adsorption fixation. The piston assembly 3 includes a piston part 31 and a one-way valve structure 32. The one-way valve structure 32 is used to open or close the exhaust hole 311 on the piston part 31. When no external force is applied, the one-way valve structure 32 acts on the exhaust hole 311, keeping the exhaust hole 311 in a normally closed state. When an external force presses the piston part 31, i.e., pressing the piston part 31 downward, the airflow in the piston chamber 12 pushes the one-way valve structure 32 upward, causing the exhaust hole 311 to open, thereby allowing the air in the piston chamber 12 to be discharged from the exhaust hole 311. After the air is discharged, the one-way valve structure 32 returns to the closed state, closing the exhaust hole 311 to prevent air backflow, maintain the negative pressure state in the piston chamber 12, and thus maintain the adsorption force. The function of the housing 4 is to facilitate the user to apply pressure to multiple piston parts 31 at the same time, making the exhaust operation more convenient and efficient, and ensuring that each piston chamber 12 can form an effective negative pressure.

[0038] In actual operation, firstly, the suction surface 11 of the double suction cup integrated suspension fixing device is brought into close contact with the surface to be installed, so that the fixing base 1 is placed stably on the surface to be installed. Then, the housing 4 is pressed repeatedly by hand. During each press, the housing 4 simultaneously drives multiple pistons 31 to move downward in the piston chamber 12. The air in the piston chamber 12 is discharged through the exhaust port 311 on the piston 31. The one-way valve structure 32 closes the exhaust port 311 after the air is discharged to prevent air backflow. As the air is discharged, a negative pressure is formed in the piston chamber 12, and the double suction cup integrated suspension fixing device is tightly adsorbed on the surface to be installed. In addition, the user can selectively apply an appropriate amount of first adhesive to the first adhesive coating part 2 according to actual needs, and then press the double suction cup integrated suspension fixing device on the surface to be installed, and wait for the first adhesive to dry and cure to further enhance the fixing effect. Since the suction hole 13 is formed at the edge of the first adhesive coating part 2, the first adhesive will not block the suction hole 13 and prevent air extraction. If the adsorption force weakens during use, the housing 4 can be pressed again to release the air, increase the negative pressure, and restore the adsorption force. It should be noted that if the adsorption force of one of the multiple piston chambers 12 weakens, pressure can also be applied to the housing 4 corresponding to that piston chamber 12. This method is a targeted selection of the pressure point on the housing 4 to control the adsorption more accurately and efficiently.

[0039] In summary, the dual-suction cup integrated suspension fixing device disclosed herein, through the design of multiple piston chambers 12 and piston assembly 3, increases the points of application of the adsorption force, enabling the dual-suction cup integrated suspension fixing device to be more firmly adsorbed onto the surface to be installed, effectively avoiding the problem of overall detachment due to the failure of a single adsorption point, and improving the stability of adsorption; combining adsorption and colloid fixing methods, when the adsorption force is sufficient, fixation is achieved through adsorption, and when the adsorption force is insufficient or a more secure fixation is required, the first colloid of the first colloid coating part 2 can be used to further enhance the fixing effect, meeting the requirements of different usage scenarios and the characteristics of the surface to be installed. Furthermore, the housing 4 is connected to multiple piston components 31, allowing users to simultaneously vent multiple piston components 31 by pressing the housing 4, eliminating the need to operate each piston component 31 individually. This significantly improves installation efficiency and makes the use of the dual-suction cup integrated suspension fixing device more convenient and faster. When the installation position needs to be changed, due to the reversibility of the adsorption fixing method, the dual-suction cup integrated suspension fixing device can be easily removed simply by breaking the negative pressure, without leaving any obvious marks on the installation surface. Additionally, if the adhesive fixing part uses removable glue, the position can be changed without damaging the installation surface, enabling the dual-suction cup integrated suspension fixing device to be reused and reducing usage costs.

[0040] In one embodiment, the piston 31 is further provided with a receiving cavity 313, an exhaust port 311 is formed at the bottom of the receiving cavity 313, and a one-way valve structure 32 is disposed in the receiving cavity 313.

[0041] In this embodiment, the piston 31 moves up and down in the piston chamber 12 and discharges air through the exhaust port 311 at the bottom of the accommodating chamber 313. The one-way valve structure 32 can control the opening and closing of the exhaust port 311 to ensure that air can only be discharged in one direction, prevent air backflow, and maintain the negative pressure in the piston chamber 12.

[0042] Reference Figure 5 As shown, in one embodiment, the one-way valve structure 32 includes a one-way valve piston 321, a fixed cover 322, and an elastic member 323. The fixed cover 322 is fixed in the accommodating cavity 313, the one-way valve piston 321 is movably disposed on the fixed cover 322, one end of the elastic member 323 abuts against the one-way valve piston 321 and the other end abuts against the fixed cover 322, and is used to push the one-way valve piston 321 to close the exhaust port 311.

[0043] In this embodiment, the fixed cover 322 is fixed within the accommodating cavity 313, providing a stable support base for the one-way valve piston 321, ensuring that the one-way valve piston 321 can move up and down on it, thereby realizing the opening and closing action of the exhaust port 311. The elastic element 323 can specifically be a compression spring, with one end of the elastic element 323 abutting against the one-way valve piston 321 and the other end abutting against the fixed cover 322. This connection method allows the elastic element 323 to always apply a downward elastic force to the one-way valve piston 321. Under normal operating conditions, the elastic force of the elastic element 323 will push the one-way valve piston 321 downward, thereby causing the one-way valve piston 321 to fit tightly against the exhaust port 311, closing the exhaust port 311 and preventing air backflow. When an external force presses down on piston 31, piston 31 moves downward within piston chamber 12. At this time, the air within piston chamber 12 is compressed, increasing the pressure. Under the influence of this air pressure, one-way valve piston 321 overcomes the elastic force of elastic element 323 and moves upward, thereby opening exhaust port 311. In this way, the air within piston chamber 12 can be smoothly discharged to the outside through exhaust port 311. When the external force is removed, piston 31 is no longer subjected to downward pressure, and elastic element 323, due to its own elastic properties, immediately pushes one-way valve piston 321 downward. Pushed downward by elastic element 323, one-way valve piston 321 re-closes exhaust port 311 tightly. In this way, it effectively prevents outside air from flowing back into piston chamber 12, thus maintaining a negative pressure state within piston chamber 12.

[0044] In one embodiment, the one-way valve structure 32 further includes a one-way valve seal 324, which is disposed at the connection between the one-way valve piston 321 and the vent 311.

[0045] In this embodiment, the one-way valve seal 324 has two configurations: one is that the one-way valve seal 324 is sleeved on the one-way valve piston 321, and the other is that the one-way valve seal 324 is located at the vent hole 311. If the one-way valve seal 324 is sleeved on the one-way valve piston 321, when the one-way valve structure 32 is in operation, the one-way valve piston 321 will reciprocate up and down within the accommodating cavity 313, and the one-way valve seal 324 sleeved on it will also move synchronously. During the process of the one-way valve piston 321 moving downward to close the vent hole 311, the one-way valve seal 324 can follow the movement of the one-way valve piston 321 to reach the corresponding position. When the one-way valve piston 321 completely closes the vent hole 311, the one-way valve seal 324 will be tightly fitted against the wall surface around the vent hole 311. Because the one-way valve seal 324 has good elasticity and flexibility, it can fill any small gaps that may exist between the one-way valve piston 321 and the vent hole 311. If the one-way valve seal 324 is located at the vent hole 311, when the one-way valve piston 321 moves upward to open the vent hole 311, the air in the piston chamber 12 can be discharged; and when the one-way valve piston 321 moves downward to close the vent hole 311, the one-way valve seal 324 located at the vent hole 311 can directly seal the vent hole 311, cooperating with the closing action of the one-way valve piston 321.

[0046] Reference Figures 9-11 As shown, in one embodiment, the piston assembly 3 further includes a negative pressure spring 33, one end of which abuts against the first colloid coating portion 2 and the other end of which abuts against the piston member 31. The piston member 31 has a first position away from the first colloid coating portion 2 and a second position close to the first colloid coating portion 2 within the piston cavity 12. The negative pressure spring 33 has an initial state and a contracted state. When the piston member 31 is in the first position, the negative pressure spring 33 is in the initial state; when the piston member 31 is in the second position, the negative pressure spring 33 is in the contracted state.

[0047] In this embodiment, the negative pressure spring sleeve 33 is disposed on the outer periphery of the accommodating cavity 313. The negative pressure spring 33 is a compression spring. When the piston 31 is in the first position, the negative pressure spring 33 is in its initial state. At this time, the negative pressure spring 33 is not compressed and maintains its natural length and elasticity. When the piston 31 is in the second position, the negative pressure spring 33 is in a contracted state. During the process of pressing the piston 31 to move it from the first position to the second position, the piston 31 applies pressure to the negative pressure spring 33, thereby compressing and storing force. When the external force is removed, the negative pressure spring 33 will restore its elastic deformation. Since one end of the negative pressure spring 33 abuts against the first colloid coating part 2 and the other end abuts against the piston 31, it will push the piston 31 to move towards the first position. During the process of the piston 31 moving towards the first position, the volume of the piston cavity 12 will gradually increase, while the amount of air in the cavity will relatively decrease, thereby further increasing the negative pressure in the piston cavity 12. By incorporating a negative pressure spring 33, after the piston 31 is pressed to release air, the spring's elasticity allows it to further increase the negative pressure within the piston chamber 12, enhancing the adsorption force. This also allows the piston 31 to remain in the first position for an extended period, resulting in a more robust and stable overall adsorption state. To ensure the negative pressure spring 33 functions properly, a limiting part 23 is provided on the side of the first colloid coating portion 2 near the piston chamber 12 to prevent displacement of the negative pressure spring 33 in a direction perpendicular to its extension and contraction direction. This ensures the negative pressure spring 33 remains in an effective working state, improving the stability and reliability of the device.

[0048] In one embodiment, the piston assembly 3 further includes a piston seal 34, which is disposed on the outer periphery of the piston assembly 31 and cooperates with the inner wall of the piston cavity 12.

[0049] In this embodiment, during the operation of the piston 31, it reciprocates within the piston cavity 12. This inevitably creates a gap between the piston 31 and the inner wall of the piston cavity 12, allowing air to easily leak out. This air leakage disrupts the negative pressure within the piston cavity 12, reducing the suction force of the dual-suction cup integrated suspension fixing device. A piston seal 34 is provided on the outer periphery of the piston 31, ensuring a tight fit with the inner wall of the piston cavity 12. As the piston 31 moves within the piston cavity 12, the piston seal 34 moves with it, maintaining an effective seal against the gap. A limit stop 312 is also provided at the top of the piston 31, cooperating with the housing 4 to precisely control the stroke of the piston 31. When an external force is applied to the piston 31, the limit stop 312 restricts the stroke, ensuring it remains within a reasonable range during pressing, guaranteeing stable exhaust performance, and allowing air in the piston cavity 12 to be discharged in a predetermined manner. At the same time, a stable stroke also helps maintain the stability of the adsorption force, ensuring that the device can continuously and reliably adsorb onto the target object.

[0050] In one embodiment, the first colloid coating part 2 includes a base plate 21 and a mesh structure 22 disposed on the surface of the base plate 21.

[0051] In this embodiment, the base plate 21 serves as the supporting foundation for the first colloid, providing support for the mesh structure 22 and ensuring the overall stability of the first colloid coating section 2. The mesh structure 22, disposed on the surface of the base plate 21, has multiple mesh openings. When the first colloid coating section 2 applies the first colloid, the first colloid fills the mesh openings of the mesh structure 22. This structure makes the distribution of the first colloid more uniform, increasing the contact area between the first colloid and the surface to be installed, thereby improving the adhesion and fixing effect of the first colloid. Simultaneously, the mesh structure 22 can also, to a certain extent, prevent the first colloid from flowing during application, maintaining the shape and position of the colloid.

[0052] In one embodiment, a second colloidal coating portion 14 is provided on the surface of the adsorption surface 11, a first colloidal coating portion 2 is provided with a first colloidal layer 5, and a second colloidal coating portion 14 is provided with a second colloidal layer 6. The first colloidal layer 5 and the second colloidal layer 6 are coplanar with the adsorption surface 11.

[0053] In this embodiment, a second colloid, such as a liquid soft adhesive, can be coated into the second colloid coating portion 14. The coplanar design of the first colloid layer 5, the second colloid layer 6, and the adsorption surface 11 not only allows for more uniform force distribution during the fixing process, but the arrangement of the first colloid coating portion 2 and the second colloid coating portion 14 also increases the contact area between the colloid and the surface to be installed, enhancing the overall fixing effect. In different application scenarios, the first colloid layer 5 and the second colloid layer 6 can be used alone or simultaneously, improving the adaptability of the dual-suction cup integrated suspension fixing device to different installation surfaces and fixing requirements.

[0054] Reference Figures 6-8 As shown, in one embodiment, the dual suction cup integrated suspension fixing device further includes a fixing member 7 fixedly connected to the fixing base 1, and the fixing member 7 is used to fix the object to be suspended 8.

[0055] In this embodiment, the specific form of the fixing component 7 can be designed according to the type of the object 8 to be hung and the usage requirements. For example, it can be a hook, a hanging ring, a slot, or a fixing shell. Taking the fixing component 7 as a fixing shell as an example, the fixing component 7 has through holes that conform to the shape of other components to ensure the normal operation of the entire double suction cup integrated suspension fixing device. The fixing component 7 also has mounting holes 71. Correspondingly, the fixing base 1 is provided with mounting posts 17. The mounting holes 71 and mounting posts 17 are fastened with screws to fix the fixing component 7, the object 8 to be hung, and the fixing base 1. By setting the fixing component 7, the object 8 to be hung can be easily fixed on the double suction cup integrated suspension fixing device to realize the suspension function.

[0056] In one embodiment, the fixed base 1 is further provided with a locking hole 15 for inserting a locking member 16 to securely connect the locking member 16 to the surface to be installed.

[0057] In this embodiment, the position and number of locking holes 15 can be designed according to requirements to ensure the tightness between the dual-suction cup integrated suspension fixing device and the surface to be installed. The dual-suction cup integrated suspension fixing device can combine three fixing methods simultaneously: negative pressure adsorption, colloid assistance, and locking fastening, greatly enhancing the overall stability of the dual-suction cup integrated suspension fixing device, adapting to various complex usage scenarios, increasing usage flexibility, and improving the user experience. For example, the first colloid layer 5 uses nail-free strong adhesive, the second colloid layer 6 uses liquid soft adhesive, and the locking component 16 can specifically be a screw. When the wall surface is uneven, such as some older walls that have been eroded over time and have pitted and uneven surfaces, or the wall material used is breathable, such as certain special lightweight brick walls or diatomaceous earth walls, it is impossible to fix items by negative pressure adsorption. In this case, permanent fixing can be achieved through the first colloid layer, which can tightly adhere to the wall surface. Even if the wall surface is uneven, the plasticity of the colloid can fill gaps and depressions, thereby providing stable support for the object to be hung. For example, on the brick walls of older buildings, the surface may be weathered and loose due to long-term exposure to air. Ordinary caulking methods often fail to ensure a sufficient and firm bond between the adhesive and the wall, resulting in poor adhesion. In such cases, screws can be driven into the wall for fixation. The strong gripping force of the screws penetrates deep into the brick, firmly locking the object to be hung and ensuring its stability. In summary, the dual-suction cup integrated hanging device combines negative pressure adsorption, adhesive assistance, and locking fastening, enabling effective fixation of objects under various environmental conditions. This significantly reduces consumer frustration caused by fixing difficulties and avoids the risk of returns due to inability to secure the product. This not only broadens the product's application environment, making it suitable for various complex wall conditions, but also, in the long run, reduces costs associated with returns and after-sales service, bringing significant benefits to both consumers and manufacturers.

[0059] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," and "above" are used herein to describe the spatial positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that spatial relative terms include not only the orientation of the component as depicted in the figures but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0060] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0061] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in sequences other than those illustrated or described herein.

[0062] This disclosure has been described through the above embodiments; however, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this disclosure to the described embodiments. Furthermore, those skilled in the art will understand that this disclosure is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of this disclosure, all of which fall within the scope of protection claimed by this disclosure. The scope of protection of this disclosure is defined by the appended claims and their equivalents.
