Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, specifically to a multifunctional suspension device. This device is mainly used to stably suspend objects in various scenarios and can be widely applied in daily life, industrial production, commercial displays, and many other fields. Background Technology

[0002] In daily life and industrial production, suspension devices are extremely common tools used to hang various objects in suitable positions for easy access, display, or storage. However, as people's demands for ease of use and versatility continue to increase, existing suspension devices are gradually revealing some problems that urgently need to be addressed.

[0003] Regarding adsorption and fixation, many suction cup-based suspension devices struggle to ensure stable adsorption under various working conditions, leading to accidental detachment and threatening the safety of the suspended objects. For example, some simple suction cup hooks rely solely on manually pressing the suction cup to expel air for adsorption. When subjected to vibration or external pulling, the suction cup easily separates from the adsorption surface due to a lack of a reliable structure to maintain the suction cup's adsorption state. Existing suspension devices generally have limitations in adjusting the suspension angle. Most devices have a fixed or limited adjustment range, failing to meet diverse usage scenarios. For instance, patent CN93243780.X describes a multi-functional suspension device consisting of a slide rail, baffle, and fixing components. The slide rail has multiple "T"-shaped grooves at the bottom, allowing for a modular structure with adjustable spacing and number of rails, achieving flexibility and ease of installation to some extent. While this device offers some flexibility in rail configuration, it lacks effective improvement in adjusting the suspension angle, making it difficult to conveniently suspend objects of different shapes and sizes at different angles. In addition, some suspension devices with angle adjustment functions have complex adjustment structures and are inconvenient to operate, which increases the difficulty and cost for users.

[0004] In summary, existing suspension devices have shortcomings in key performance aspects such as adsorption stability and suspension angle adjustment. There is an urgent need for a newly designed multifunctional suspension device to solve these problems and meet the growing market demand. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional suspension device to address the shortcomings of existing suspension devices in terms of adsorption stability and suspension angle adjustment. This device aims to ensure that the suction cup remains stably in an adsorption state under various working conditions, while providing flexible and convenient suspension angle adjustment to meet diverse application needs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-functional suspension device includes a suction cup cover, a suction cup, and a pull rod attached to the suction cup. The suction cup is configured to switch between a detached state and an adsorbed state under the actuation of the pull rod. The multi-functional suspension device further includes:

[0008] A hanging rack for hanging objects; and

[0009] A connecting rod is used to connect the hanger and the pull rod;

[0010] The bracket is rotatably pivotally connected to the first end of the connecting rod, and the second end of the connecting rod is pivotally connected to the pull rod by a pin. Furthermore, the connecting rod and the top surface of the suction cup cover are in abutting contact through a cam structure, so that the suction cup can be driven to switch between the separation state and the suction state by rotating the connecting rod.

[0011] Furthermore, the cam structure has an inclined or undulating cam surface, and the state of the suction cup is switched by changing the pressure position between the cam surface and the top surface. This design allows the pressure position between the cam surface and the top surface to change during the rotation of the connecting rod, thereby pulling the suction cup to move and realizing the switching between the separation state and the suction state of the suction cup.

[0012] Furthermore, the cam surface has a retaining portion that holds the suction cup in an adsorbed state. When the suction cup is in an adsorbed state, the retaining portion ensures that the suction cup maintains a stable adsorbed state even when subjected to a certain external force or vibration, effectively preventing the suction cup from accidentally falling off and improving the safety and reliability of the suspension device.

[0013] Furthermore, the direction in which the suction cup moves from the separated state to the adsorbed state is defined as the first direction, and the hanger is configured to rotate around the first direction. This design allows the hanger to be flexibly adjusted in the first direction to meet the hanging angle requirements of different objects.

[0014] Furthermore, a pivot shaft is defined on the first end of the connecting rod, and a pivot hole is defined on the hanger. The pivot hole and the pivot shaft are rotatably adapted to each other. Through this pivot structure, the hanger can rotate smoothly around the pivot shaft, realizing flexible adjustment of the suspension angle.

[0015] To further enhance the connection stability between the bracket and the connecting rod, the top of the first end has a snap-fit ​​hole, and the bracket has a snap-fit ​​hook. The snap-fit ​​hook and the snap-fit ​​hole engage to prevent the bracket and the connecting rod from separating along the first direction. This snap-fit ​​structure effectively prevents the bracket and the connecting rod from accidentally separating during use, improving the overall stability of the device.

[0016] Furthermore, the pin is arranged perpendicular to the first direction. This arrangement allows the connecting rod to more stably drive the suction cup state transition when rotating around the pin, and also helps to improve the structural stability of the entire device.

[0017] Furthermore, the hanger includes a first mounting portion and a second mounting portion, both of which are capable of rotating independently around the first direction. This design allows the hanger to independently adjust the angles of the two portions according to different suspension requirements, further improving the flexibility and adaptability of the suspension device.

[0018] Furthermore, the rotation angle of the first and second coupling parts is from 0° to 90°. This large rotation angle range can meet more diverse suspension angle requirements, making this multifunctional suspension device suitable for various different usage scenarios.

[0019] Furthermore, the connecting rod has a separately configured positioning member; the positioning member has a positioning hole for the pin to pass through, and it is clamped between the positioning part of the connecting rod and the top surface, so that a stable pressing contact is maintained between the connecting rod and the top surface. The design of the positioning member ensures that the connecting rod maintains a stable pressing contact with the top surface of the suction cup cover during rotation, thereby ensuring that the cam structure can accurately drive the suction cup state transition, improving the reliability and stability of the device.

[0020] The beneficial effects of this utility model are as follows:

[0021] (1) Through the design of the cam structure, especially the retaining part on the cam surface, it can be ensured that the suction cup can be stably in the adsorption state under different working conditions, effectively preventing the suction cup from falling off accidentally, and improving the safety and reliability of the suspension device.

[0022] (2) The bracket can rotate around the first direction and includes a first hook part and a second hook part. Both parts can rotate independently around the first direction with a rotation angle of 0° to 90°. This design allows the suspension device to be flexibly adjusted according to different suspension requirements, meeting the diverse needs of different usage scenarios.

[0023] (3) The design of the pivot structure, snap-fit ​​structure and positioning parts between the connecting rod and the bracket enhances the overall stability of the device, ensures that the connection between the components is firm during use, and improves the reliability and service life of the device.

[0024] In summary, the multifunctional suspension device of this invention effectively solves the shortcomings of existing suspension devices in terms of adsorption stability and suspension angle adjustment, and has significant technological progress and practical value.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0041] Example 1:

[0042] like Figure 1-7 As shown in the figure, this multifunctional suspension device aims to address the shortcomings of existing suspension devices in terms of adsorption stability and suspension angle adjustment. The following detailed description of specific embodiments of this invention, in conjunction with the accompanying drawings, will more clearly demonstrate its structural composition, working principle, and beneficial effects.

[0043] This embodiment provides a multifunctional suspension device, which mainly includes a suction cup cover 1, a suction cup 2, a pull rod 3, a hanger 4, and a connecting rod 5. The suction cup 2 can switch between a detached state and an adsorption state under the drive of the pull rod 3. The hanger 4 is used to suspend objects, and the connecting rod 5 connects the hanger 4 and the pull rod 3. The hanger 4 is rotatably pivotally connected to the first end of the connecting rod 5, and the second end of the connecting rod 5 is pivotally connected to the pull rod 3 via a pin 6. Furthermore, the connecting rod 5 and the top surface of the suction cup cover 1 are in abutting contact via a cam structure. Rotation of the connecting rod 5 drives the suction cup 2 to switch between a detached state and an adsorption state.

[0044] like Figures 1-4 As shown, suction cup 2 has a circular structure and is made of high-quality rubber material, possessing good elasticity and sealing properties. The suction cup cap 1 has a diameter slightly smaller than suction cup 2 and fits tightly against the top of suction cup 2. One end of the pull rod 3 is fixedly connected to suction cup 2, and the other end is connected to the second end of connecting rod 5. When an external force is applied to the pull rod 3, it causes the suction cup 2 to shift, thus achieving the transition between the separated and adsorbed states of suction cup 2. For example, when the pull rod 3 pulls the suction cup 2 to bulge, a negative pressure space is formed between suction cup 2 and the adsorption surface. Under atmospheric pressure, suction cup 2 is tightly adsorbed onto the adsorption surface; at this time, suction cup 2 is in the adsorption state. When the pull rod 3 pushes the suction cup 2 back to flat, suction cup 2 separates from the adsorption surface, and is in the separated state.

[0045] A pivot shaft 51 is defined on the first end of the connecting rod 5, and a pivot hole 43 is defined on the bracket 4. The pivot hole 43 and the pivot shaft 51 can be rotatably fitted together. The diameter of the pivot shaft 51 is slightly larger than the diameter of the pivot hole 43 to ensure that the bracket 4 can rotate smoothly around the pivot shaft 51, thus achieving the initial adjustment of the suspension angle. In practical applications, when it is necessary to adjust the suspension angle of the bracket 4, simply rotate the bracket 4 slightly to change the angle of the bracket 4.

[0046] like Figure 3 or Figure 5 As shown, to further enhance the connection stability between the bracket 4 and the connecting rod 5, the top of the first end has a snap-fit ​​hole 52, and the bracket 4 has a snap-fit ​​hook 44. The snap-fit ​​hook 44 and the snap-fit ​​hole 52 engage to prevent the bracket 4 and the connecting rod 5 from separating in the first direction. The shape of the snap-fit ​​hook 44 matches the snap-fit ​​hole 52. During assembly, the snap-fit ​​hook 44 of the bracket 4 is aligned with the snap-fit ​​hole 52 of the connecting rod 5, and the bracket 4 is pressed down to make the snap-fit ​​hook 44 snap into the snap-fit ​​hole 52. The snap-fit ​​hook 44 is configured to be elastic for easy installation. This snap-fit ​​structure effectively prevents the bracket 4 and the connecting rod 5 from accidentally separating during use, improving the overall stability of the device.

[0047] like Figure 1 or Figure 2 or Figure 8 As shown, the second end of the connecting rod 5 is pivotally connected to the pull rod 3 via a pin 6. It is arranged perpendicular to the direction that moves the suction cup 2 from the separated state to the adsorption state (defined as the first direction). This arrangement allows the connecting rod 5 to more stably drive the suction cup 2 through state transitions as it rotates around the pin 6, while also contributing to improved structural stability of the entire device. When the connecting rod 5 rotates around the pin 6, it causes displacement of the suction cup 2, which in turn drives the suction cup 2 to switch between the separated and adsorption states via a cam structure.

[0048] like Figure 2 or Figure 4 As shown, the cam structure has an inclined cam surface 7. The state of the suction cup 2 is changed by the change in the pressing position between the cam surface 7 and the top surface of the suction cup cover 1. During the rotation of the connecting rod 5, the pressing position between the cam surface 7 and the top surface changes, thereby pushing the suction cup 2 to move. In this embodiment, when the connecting rod 5 rotates clockwise, the inclined part of the cam surface 7 gradually contacts the top surface of the suction cup cover 1, pushing the suction cup 2 downward, thus changing the suction cup 2 to the separation state; when the connecting rod 5 rotates counterclockwise, the other part of the cam surface 7 contacts the top surface of the suction cup cover 1, pushing the suction cup 2 upward, thus changing the suction cup 2 to the adsorption state.

[0049] The cam surface 7 has a retaining part 71 that holds the suction cup 2 in the adsorption state. When the suction cup 2 is in the adsorption state, the retaining part 71 ensures that the suction cup 2 maintains a stable adsorption state even when subjected to certain external forces or vibrations, effectively preventing the suction cup 2 from accidentally falling off and improving the safety and reliability of the suspension device. For example, in some industrial environments, the suspension device may be subjected to machine vibrations or external pulling forces; the retaining part 71 ensures that the suction cup 2 is always firmly adsorbed on the adsorption surface, guaranteeing the safety of the suspended object.

[0050] like Figure 1 or Figure 7 As shown, the hanger 4 includes a first hook-on portion 41 and a second hook-on portion 42, both of which can rotate independently around a first direction. The rotation angle of the first hook-on portion 41 and the second hook-on portion 42 is from 0° to 90°. This design allows the hanger 4 to independently adjust the angles of the two portions according to different hanging requirements, further improving the flexibility and adaptability of the hanging device. For example, when it is necessary to hang an irregularly shaped object, the angles of the first hook-on portion 41 and the second hook-on portion 42 of the hanger 4 can be adjusted separately so that the object can be stably suspended on the hanger 4.

[0051] like Figure 4As shown, the connecting rod 5 has a positioning element 8 separately configured therewith. The positioning element 8 has a positioning hole 81 through which the pin 6 passes, and it is clamped between the positioning part 53 of the connecting rod 5 and the top surface of the suction cup cover 1, so that the connecting rod 5 and the top surface of the suction cup cover 1 maintain a stable pressing contact. The design of the positioning element 8 ensures that the connecting rod 5 maintains a stable pressing contact with the top surface of the suction cup cover 1 during rotation, thereby ensuring that the cam structure can accurately drive the suction cup 2 to change state, improving the reliability and stability of the device. During the use of the device, the positioning element 8 can prevent the connecting rod 5 from loosening or separating from the top surface of the suction cup cover 1, ensuring the normal operation of the cam structure.

[0052] like Figures 1-8 As shown, when an object needs to be suspended on a flat surface, the suction cup 2 is first placed at a suitable position on the surface. Then, by rotating the connecting rod 5, the inclined portion of the cam surface 7 gradually contacts the top surface of the suction cup cover 1, pushing the suction cup 2 upward. A negative pressure space is formed between the suction cup 2 and the surface, and the suction cup 2 is tightly adhered to the surface under atmospheric pressure. At this time, the holding portion 71 of the cam surface 7 ensures that the suction cup 2 maintains a stable adsorption state. For example, in a home environment, when this suspension device is used to hang kitchen knives, a simple rotation of the connecting rod 5 can firmly attach the suction cup 2 to the tiled wall, ensuring the safe hanging of the knives.

[0053] After the suction cup 2 is in the adsorption state, if it is necessary to adjust the hanging angle of the bracket 4, the first hook part 41 and the second hook part 42 of the bracket 4 can be rotated respectively. Since both parts of the bracket 4 can rotate independently around the first direction, and the rotation angle is from 0° to 90°, the angle of the bracket 4 can be flexibly adjusted according to the shape of the object and the hanging requirements. For example, in a commercial display scenario, when it is necessary to hang a tilted painting, the angle of the bracket 4 can be adjusted so that the painting can be hung on the display wall at the optimal display angle.

[0054] When it is necessary to remove the suspended object, simply rotate the connecting rod 5 in the opposite direction so that the other part of the cam surface 7 contacts the top surface of the suction cup cover 1, pushing the suction cup 2 downward and separating it from the suction surface. At this time, the object on the hanger 4 can be easily removed. For example, on an industrial production line, when it is necessary to replace suspended parts, the suction cup 2 can be quickly removed by simply rotating the connecting rod 5, and the parts can be replaced.

[0055] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
