Description

Technical Field

[0001] This utility model relates to the field of suction cup hook technology, and more specifically, to a large-load suction cup hook. Background Technology

[0002] With rising living standards and a growing demand for efficient use of home space, many consumers prefer hook solutions that don't require drilling. Suction cup hooks, as a non-marking and movable hook device, are widely used because they can form a strong adhesive bond on smooth surfaces.

[0003] However, most existing suction cup hooks have problems such as insufficient suction force, limited load-bearing capacity, and narrow applicable scenarios. Especially on high loads or uneven surfaces, existing suction cup hooks often have difficulty maintaining stability and long-term suction force.

[0004] Therefore, there is a need for a suction cup hook that can provide stronger adhesion, higher load-bearing capacity, and adaptability to various usage scenarios. Utility Model Content

[0005] The purpose of this invention is to provide a high-load suction cup hook that addresses the problems existing in the prior art.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A high-load suction cup hook, comprising:

[0008] A base plate, on one side of which a suction cup assembly is provided. The suction cup assembly consists of a main suction cup body and multiple small suction cup cavities. The multiple small suction cup cavities are located inside the main suction cup body. A negative pressure assembly is provided on one side of the base plate located on the suction cup assembly.

[0009] A slide rail is provided on the side of the base plate away from the suction cup assembly. A support plate is slidably mounted on the base plate on the slide rail. A hook body is provided on the support plate. A sliding assembly is provided between the support plate and the base plate.

[0010] As a preferred embodiment of this utility model, the number of the plurality of small suction cup cavities is greater than or equal to six, arranged in a ring at the bottom of the main suction cup body, and the arrangement is a equidistant circumferential arrangement.

[0011] As a preferred embodiment of this utility model, the main suction cup body has multiple negative pressure cavities in the middle, and the multiple small suction cup cavities are respectively connected to the multiple negative pressure cavities. The bottom plate has a main cavity in the middle, and the multiple negative pressure cavities are all connected to the main cavity.

[0012] The negative pressure assembly includes a piston that slides in a sealed manner in the middle of the main cavity. A pull rod is provided outside the main cavity and is fixedly connected to the piston. A limit assembly is provided on one side of the bottom plate located on the pull rod.

[0013] As a preferred embodiment of this utility model, the limiting component includes teeth fixedly arranged side by side on the pull rod, the teeth being inclined on the side away from the piston, a slide rail being provided on the side of the base plate located on the teeth, a limiting rod being slidably arranged in the slide rail, the limiting rod being abutting against the teeth, a first spring being sleeved in the middle of the limiting rod, and the two ends of the first spring being fixedly connected to the limiting rod and the base plate respectively.

[0014] As a preferred embodiment of this utility model, the side of the support plate is provided with a positioning groove, and multiple positioning grooves are provided and arranged side by side along the support plate.

A second spring is sleeved in the middle of the positioning rod, and the two ends of the second spring are fixedly connected to the positioning rod and the support plate, respectively.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. Enhanced adsorption capacity and adaptability to various wall surfaces: The combination structure of the main suction cup body and multiple small suction cup cavities forms a strong negative pressure adsorption on smooth surfaces; the multiple small suction cup cavities form multiple local adsorption points, enhancing the adaptability to rough or uneven surfaces and improving the overall adsorption force and stability; the multiple small suction cups are arranged in a ring at equal intervals, making the suction force distribution more uniform, avoiding local lifting or slippage, and improving load-bearing performance.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Example

[0028] like Figure 1-4 As shown, a high-load suction cup hook includes:

[0029] The base plate 1 has a suction cup assembly 2 on one side. The suction cup assembly 2 consists of a main suction cup body 21 and multiple small suction cup cavities 22. The multiple small suction cup cavities 22 are located inside the main suction cup body 21. The base plate 1 has a negative pressure assembly 3 on one side of the suction cup assembly 2.

[0030] A slide rail 4 is provided on the side of the base plate 1 away from the suction cup assembly 2. A support plate 5 is slidably mounted on the base plate 1 on the slide rail 4. A hook body 6 is mounted on the support plate 5. A sliding assembly 7 is provided between the support plate 5 and the base plate 1.

[0031] In a further embodiment, the base plate 1 serves as the load-bearing foundation of the entire hook structure, connecting and supporting various components. The main suction cup body 21 forms a preliminary vacuum adsorption through contact with a smooth surface, providing basic adhesion. Multiple small suction cup cavities 22 can respectively form multiple local negative pressure zones, which can also improve the adsorption effect on rough or uneven surfaces, thereby improving the overall load-bearing capacity and applicability. The negative pressure component 3 assists the suction cup component 2 in forming and maintaining negative pressure, enhancing the adsorption force. During use, air is pumped out to form negative pressure inside the suction cup, thereby making the suction cup firmly adsorbed on the wall or other surfaces, preventing it from falling off due to the hanging of heavy objects.

[0032] The slide rail 4 provides a sliding guide channel for the support plate 5. The support plate 5 serves as a structural part that supports the hook, and the position of the hook can be changed by sliding adjustment to adapt to different usage scenarios. The hook body 6 is used to suspend objects and is the direct load-bearing component of the entire device. The sliding component 7 maintains a certain degree of locking when the hook position is adjusted smoothly to prevent the support plate 5 from sliding out of position when bearing weight.

[0033] Specifically, there are six or more small suction cup cavities 22 arranged in a ring at the bottom of the main suction cup body 21, with the arrangement being equidistant circumferential.

[0034] In a further embodiment, a sufficient number of negative pressure cavities 31 are provided to increase the total amount and uniformity of the adsorption force. The annular and equidistant arrangement ensures that the suction force is evenly distributed at the bottom of the entire main suction cup body 21, avoiding local lifting or slippage due to concentrated suction force. Each small suction cup cavity 22 supports each other, enhancing the overall stability and shear resistance.

[0035] Specifically, the main suction cup body 21 has multiple negative pressure chambers 31 in the middle, and multiple small suction cup cavities 22 are connected to the multiple negative pressure chambers 31 respectively. The bottom plate 1 has a main cavity 32 in the middle, and the multiple negative pressure chambers 31 are all connected to the main cavity 32.

[0036] The negative pressure assembly 3 includes a piston 33 that slides in the middle of the main cavity 32. A pull rod 34 is provided on the outside of the main cavity 32. The pull rod 34 is fixedly connected to the piston 33. A limit assembly 8 is provided on one side of the bottom plate 1 located on the pull rod 34.

[0037] In a further embodiment, multiple negative pressure chambers 31 serve as negative pressure channels connecting the main chamber 32 and each small suction cup cavity 22. Through these chambers, the negative pressure generated by the main chamber 32 is evenly transmitted to the small suction cup cavities 22, thereby enhancing and evenly distributing the suction force of the entire suction cup assembly 2. The piston 33 slides back and forth to generate gas discharge, thereby creating negative pressure in the main chamber 32. The piston 33 is controlled by the pull rod 34 to slide, thereby controlling the air pressure inside the main chamber 32 and the multiple negative pressure chambers 31.

[0038] Specifically, the limiting component 8 includes teeth 81 fixedly arranged side by side on the pull rod 34. The teeth 81 are inclined on the side away from the piston 33. The base plate 1 has a slide rail 82 on one side of the teeth 81. A limiting rod 83 is slidably arranged in the slide rail 82. The limiting rod 83 abuts against the teeth 81. A first spring 84 is sleeved in the middle of the limiting rod 83. The two ends of the first spring 84 are fixedly connected to the limiting rod 83 and the base plate 1, respectively.

[0039] In a further embodiment, the inclined surface of the tooth 81 allows the limiting rod 83 to slide over when the pull rod 34 moves forward, while the stepped surface prevents the pull rod 34 from rebounding, achieving one-way locking. This design allows the pull rod 34 to "go further forward as it is pulled," but it cannot easily retract, thus maintaining the internal negative pressure without leakage. The slide 82 provides a sliding guide for the limiting rod 83. Under the force of the first spring 84, the limiting rod 83 always presses against the tooth 81. When the pull rod 34 is pulled, the inclined surface of the tooth 81 pushes the limiting rod 83 to temporarily retract. After the pull rod 34 stops, the limiting rod 83 rebounds under the force of the spring and locks the tooth 81, forming a ratchet-like locking structure to prevent the piston 33 from rebounding and ensure continuous negative pressure.

[0040] Specifically, the side of the support plate 5 is provided with a positioning groove 71. Multiple positioning grooves 71 are provided and are arranged side by side along the support plate 5. The sliding component 7 includes a positioning rod 72 that slides through the bottom plate 1 to the slide rail 4. The positioning rod 72 is slidably engaged with the positioning groove 71. A second spring 73 is sleeved in the middle of the positioning rod 72. The two ends of the second spring 73 are fixedly connected to the positioning rod 72 and the support plate 5, respectively.

[0041] In a further embodiment, the positioning groove 71 serves as a locking hole for the positioning rod 72 to be inserted, providing multiple selectable positions to achieve multi-stage adjustability of the support plate 5. The positioning rod 72 is inserted into the corresponding positioning groove 71 to achieve locking. The second spring 73 provides a continuous elastic force in the direction of the positioning groove 71, so that the positioning rod 72 always remains in the locked state when the user does not stretch it. The operation is convenient; the support plate 5 can be moved simply by stretching it, and it automatically locks after being released.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
