Description

Technical Field

[0001] The utility model relates to a suction cup device, in particular to a suction cup device with a simple hook. The suction cup device can be adsorbed on fixed surfaces of various angles, and the hook on the suction cup device can hang objects. Background Art

[0002] Suction cup devices are widely used in various fields of production and life because they can be detachably and tracelessly adsorbed and fixed on fixed surfaces such as walls and mirrors. Early suction cup hooks simply set a hook on the back of the suction cup. The suction cup of this structure has insufficient adsorption force and is easily separated from the fixed surface after a long time or when heavy objects are hung.

[0003] In order to increase the suction force of the suction cup, so that the suction cup device can be more firmly and lastingly adsorbed, and can bear a larger weight, some suction cup devices with a pressurization function have come into being. For example, the utility model patent with the authorization announcement number CN218528423U discloses a suction cup hook, including a hook body, a suction cup, a spring and a rotating button; the suction cup includes a flexible deformation part and a connecting rod, the spring is sleeved on the connecting rod, and the rotating button is rotatably connected to the front end of the connecting rod and has a lifting state and a buckled state relative to the hook body; when the rotating button is pressed to switch to the buckled state: the rotating button pulls the middle part of the flexible deformation part forward through the connecting rod, the edge of the flexible deformation part abuts against the edge of the installation cavity, and the rear side of the flexible deformation part forms a concave arc surface. Such a suction cup device has a strong suction force, and a storage basket, a storage rack, etc. can be hung on its hook, or several suction cup devices and storage devices can form a suction cup storage assembly.

In addition, based on its application scenario, this type of suction cup structure can only be used when it is adsorbed on a vertical fixed surface, which is limited to the use scenario of a single hook.

DETAILED DESCRIPTION

[0047] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0048] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. "First" and "second" are only for the purpose of making the description easier to understand, without any other directional meaning, and cannot be used as a limitation on the present utility model.

[0049] like Figures 1 to 7 The suction cup device 100 with a simple hook provided in this embodiment includes a device body 10, a booster wrench 20, a flexible suction cup 30 and a hook member 40. The flexible suction cup 30 is arranged on the front side of the device body 10, and the booster wrench 20 and the hook member 40 are arranged on the back side of the device body 10.

[0050] like Figure 3 and Figure 4 As shown, the booster wrench 20 includes a first end 21 and a second end 22. The hook member 40 includes an axis pin portion 41, a hook portion 42, and an arm portion 43 connecting the axis pin portion 41 and the hook portion 42. The axis pin portion 41 rotatably connects the flexible suction cup 30 to the first end 21 of the booster wrench 20, and the hook portion 42 is used to hang an object.

[0051] like Figure 4 Combination Figure 1As shown, the booster wrench 20 uses the shaft pin portion 41 as an axis, and switches between a pulled-up state in which the second end 22 is away from the back side of the device body 10, and a compressed state in which the second end 22 is against the back side of the device body 10. When the booster wrench 20 is in the pulled-up state, the device body 10 and the flexible suction cup 30 are in a released state. The front surface of the flexible suction cup 30 is pressed against the fixed surface g, and the booster wrench 20 is pulled to rotate in the direction in which the second end 22 is close to the back side of the device body 10. At this time, the flexible suction cup 30 is pulled and deformed, and the front side of the device body 10 gradually compresses the flexible suction cup 30 until the second end 22 of the booster wrench 20 is against the back side of the device body 10 and comes to a compressed state. The device body 10 is used to vacuum-compress the flexible suction cup 30 against the fixed surface g. At this time, the suction cup device 100 with a simple hook is adsorbed and fixed on the fixed surface g. At this time, the hook member 40 can rotate with the shaft pin portion 41 as the axis.

[0052] It can be seen that the suction cup device 100 with a simple hook provided by the utility model realizes vacuum pressurization of the flexible suction cup 30 through the booster wrench 20, so as to improve the adsorption force and firmness of the suction cup device to the fixed surface; the hook member 40 is formed by bending a metal wire, and a part of it is used as an axle pin for rotatably connecting the booster wrench 20 and the flexible suction cup 30, and the multi-functional one realizes the intensive and simple overall structure, and reduces the production cost; the hook member 40 can further rotate with the axle pin portion 41 as the axis, such as Figure 1 , Figure 2 and Figure 6 , Figure 7 As shown, the suction cup device can be supported to be adsorbed on a vertical, horizontal or inclined fixed surface, expanding the application scope and application scenarios of the suction cup hook.

[0053] like Figure 3 and Figure 4 As shown, a connection seat 31 is convexly provided on the back side of the flexible suction cup 30, and a shaft connection hole 32 is provided on the connection seat 31. A connection hole 11 matching the shape of the connection seat 31 is provided on the device body 10, and a shaft interface 23 is provided on the first end 21 of the booster wrench 20. The connection seat 31 passes through the connection hole 11, and the shaft interface 23 of the booster wrench 20 and the shaft connection hole 32 of the connection seat 31 are opposite to form a shaft connection channel h. The shaft pin portion 41 of the hook member 40 is inserted into the shaft connection channel h to rotatably connect the flexible suction cup 30 to the first end 21 of the booster wrench 20.

[0054] Further, in this embodiment, the shaft connection hole 32 is transversely opened in the connecting seat 31, the boost wrench 20 is shell-shaped, and shaft interfaces 23 are respectively opened on both sides of the boost wrench 20. The connecting seat 31 passes through the connecting hole 11 and is inserted into the first end 21 of the shell-shaped boost wrench 20, and the shaft interface 23 of the boost wrench 20 and the shaft connection hole 32 of the connecting seat 31 are opposite to form a shaft connection channel h.

[0055] like Figure 3 and Figure 4 As shown, the hook member 40 is formed by bending a metal wire, which not only has better structural strength, but also has a simple structure and reduces production costs. The two free ends of the metal wire are bent inward to form a left shaft pin section 41a and a right shaft pin section 41b, respectively. There is a distance between the left shaft pin section 41a and the right shaft pin section 41b, forming a shaft pin section 41. The shaft pin section 41 continues to extend to form two external expansion ears 44 to make way for the first end 21 of the booster wrench 20. The two external expansion ears 44 are butt-jointed at the ends and extend side by side to form an arm section 43, and the end of the arm section 43 is turned and hooked to form a hook section 42. Therefore, the arm section 43 and the hook section 42 are formed by folding the metal wire in half and putting them together, and their structural strength and bearing capacity are stronger and not easy to deform.

[0056] The left shaft pin section 41a and the right shaft pin section 41b are respectively inserted into the shaft connection channel h from both sides, so that the flexible suction cup 30 is rotatably shaft-connected to the first end 21 of the boost wrench 20. In other embodiments, the two free ends of the metal wire can be bent outward to form the left shaft pin section 41a and the right shaft pin section 41b, respectively, the middle of the connecting seat 31 is hollowed out, and there is a space in the middle of the shaft connection channel h. The left shaft pin section 41a and the right shaft pin section 41b are inserted into the shaft connection channels h on both sides from the hollowed-out middle of the connecting seat 31, so that the flexible suction cup 30 is rotatably shaft-connected to the first end 21 of the boost wrench 20. In this way, the left shaft pin section 41a and the right shaft pin section 41b can be butted and extended in parallel to form the arm section 43, without forming the external expansion ear 44.

[0057] However, the structure adopted in this embodiment has better structural strength, and there is a distance between the left shaft pin section 41a and the right shaft pin section 41b, which is more convenient to assemble. In addition, the shell-shaped design of the supercharging wrench 20 can hide the connecting seat 31 therein, and the appearance is more complete and beautiful under the premise of ensuring the supercharging function.

[0058] like Figure 4 As shown, a buckle k1 is convexly provided on the inner side of the second end 22 of the booster wrench 20, and a buckle hole k2 matching the buckle k1 is provided on the back side of the device body 10. When the booster wrench 20 is in a compressed state, the buckle k1 is buckled into the buckle hole k2 to prevent the second end 22 of the booster wrench 20 from being separated from the back side of the device body 10, thereby ensuring that the booster wrench 20 continues to maintain a compressed state, and the suction of the suction cup device is more firm and lasting. In addition, when the suction cup device is adsorbed on an inclined or horizontal fixed surface g, the booster wrench 20 will not be separated from the device body.

[0059] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0060] The above is an introduction to the suction cup device with a simple hook provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
