Description

Technical Field

[0001] This utility model relates to suction cup bases and their application fields, specifically to a suction cup base and hooks and row hooks made therefrom. Background Technology

[0002] Existing suction cup bases can serve as the fixed installation foundation for various shelves or hooks. Based on the control method of the suction cup pull rod, they can be divided into knob type and rocker arm type. The knob type uses the rotation of the knob to control the pulling distance of the pull rod through the rise and fall of the spiral surface, while the rocker arm type controls the pulling distance of the pull rod through the hinge with the pull rod and the eccentric structure at the end of the rocker arm. Therefore, from a visual point of view, the overall aesthetics of the knob type are far superior to those of the rocker arm type. However, due to the advantage of simple structure, the rocker arm type has become an indispensable control method. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a suction cup base that combines the aesthetics of a knob type with the simplicity of a rocker arm type, achieving good aesthetics and effectively hiding the rocker arm / handle, as well as hooks and hook arrays made from it.

[0004] To address the above problems, the following technical solution is provided: a suction cup base, including a fixed bracket, a suction cup mounting position on the back of the fixed bracket, a suction cup mounted on the suction cup mounting position, the back of the suction cup being the adsorption surface, and a pull rod passing through the fixed bracket on the front of the suction cup; an eccentric rod is hinged to one end of the pull rod protruding from the front of the fixed bracket, the eccentric rod and the front of the fixed bracket serving as support points and swinging along the hinge axis, the swinging end of the eccentric rod moving towards the front of the fixed bracket to pull the pull rod so that the suction cup is adsorbed, while the eccentric rod is at a dead point position or beyond the dead point position to lock the swing angle, and also including a swing cover, the swinging end of the eccentric rod being hinged to the swing cover, and when the eccentric rod is at a dead point position or beyond the dead point position, the back of the swing cover moving towards or abutting the front of the fixed bracket and covering the pull rod and eccentric rod inside the swing cover.

[0005] The present invention is further configured such that the eccentric rods are two parallel rods spaced apart from each other, and the two eccentric rods are connected by a crossbeam; the end of the pull rod is hinged between the two eccentric rods; and the other end of the two eccentric rods is hinged to the swing cover.

[0006] The present invention is further configured such that the ends of the two eccentric rods away from the pull rod are provided with protruding quick-release pins on the side facing each other or away from each other; the swing cover is provided with quick-release buckles that are adapted to and hinged to the quick-release pins.

[0007] The present invention is further configured such that the quick-release buckle consists of two elastic ribs spaced apart from each other and connected to the back of the swing cover. The elastic ribs are provided with quick-release holes for fitting with quick-release pins. The outer edge of the side of the elastic rib facing the eccentric rod where the quick-release pin is located is provided with a guide slope. When the quick-release pin is inserted, its end fits with the guide slope, causing the elastic ribs to undergo elastic deformation, thereby causing the quick-release pin to engage with the quick-release hole.

[0008] The present invention is further provided with an anti-misalignment mechanism between the fixed bracket and the swing cover to prevent the swing cover from being misaligned when the swing cover approaches or abuts against the fixed bracket.

[0009] The present invention is further configured such that the anti-misalignment mechanism includes two sets of quick-release buckles spaced 180 degrees apart along the circumferential direction of the swing cover, and a positioning protrusion on the front of the fixed bracket; when the swing cover is fastened to the front of the fixed bracket, one set of quick-release buckles is hinged to the eccentric rod, and the other set of quick-release buckles is engaged with the positioning protrusion.

[0010] The present invention is further configured such that the end of the pull rod is hinged to the eccentric rod by a hinge pin.

[0011] A hook, wherein the fixing bracket has one or more hook bodies.

[0012] A hook assembly includes two sets of suction cup bases, with a mounting base between the two suction cup bases, and one or more hook bodies on the mounting base.

[0013] The present invention is further configured such that the seat is provided with a hook groove, and the lower side of the hook body is hinged to the hook groove; when the hook body is retracted, it is located in the hook groove, and when the hook body is extended forward, its upper end swings outward from the hook groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. When the swing end of the eccentric rod moves from being vertical to the front of the fixed bracket to approaching the front of the fixed bracket, the eccentric structure at the hinge position pulls the tie rod to reach or pass the dead point position. When it reaches or passes the dead point position, the side of the eccentric rod will abut against the front of the fixed bracket due to the reverse pulling force of the tie rod. Therefore, when a swing cover is set at the end of the eccentric rod, it can be ensured that the swing cover also approaches or abuts against the front of the fixed bracket. The swing cover is used to cover the eccentric rod and the tie rod, so that it is no different from the knob structure in appearance, ensuring the overall aesthetics and the simplicity of the structure.

[0016] 2. When disassembly is required, simply pull the swing cover away from the front of the fixed bracket. At the same time, the swing cover will also pull the eccentric rod away from the front of the fixed bracket, thereby relieving the tension on the pull rod and releasing the negative pressure on the suction cup.

[0017] 3. The eccentric rod consists of two cooperating crossbeams, which can effectively improve the hinge rigidity between the eccentric rod, the tie rod, and the swing cover;

[0018] 4. The eccentric rod and tie rod are first hinged together by hinge pins, so sufficient assembly space needs to be reserved; quick-release pins and quick-release buckles can be directly connected by snap-fit ​​in the later stage of assembly to ensure the reliability of the assembly process;

[0019] 5. The quick-release pin is engaged by guiding the elastic deformation of the inclined surface and elastic rib, and the hinge function is achieved after engagement while preventing it from coming out.

[0020] 6. Since the swing cover is connected to the pull rod through the eccentric rod, there is a risk of misalignment. The anti-misalignment mechanism can effectively stabilize the swing cover after it is fastened. The quick-release buckles are set at 180-degree intervals along the circumferential direction of the swing cover. At any 180-degree position, the quick-release buckle on the other side can be engaged with the positioning protrusion while hinged with the eccentric rod, thus improving assembly efficiency.

Detailed Implementation

[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0032] Example 1

[0033] refer to Figures 1 to 9 ,like Figures 1 to 7 The suction cup base shown includes a fixed bracket 10. A suction cup mounting position 11 is provided on the back of the fixed bracket 10, and a suction cup 20 is mounted on the mounting position 11. The back of the suction cup 20 is the adsorption surface, and a pull rod 21 passing through the fixed bracket 10 is provided on the front of the suction cup 20. An eccentric rod 30 is hinged to one end of the pull rod 21 protruding from the front of the fixed bracket 10. The eccentric rod 30 and the front of the fixed bracket 10 serve as support points, swinging along the hinge axis. The swinging end of the eccentric rod 30 moves towards the front of the fixed bracket 10 to pull the pull rod 21, causing the suction cup 20 to adhere. Simultaneously, the eccentric rod 30 is at a dead point position or exceeds the dead point position, thus locking the swing angle (see reference). Figure 2 The system also includes a swing cover 40, the swing end of the eccentric rod 30 is hinged to the swing cover 40, and when the eccentric rod 30 is in the dead position or passes the dead position, the back of the swing cover 40 moves towards or abuts against the front of the fixed bracket 10, and the pull rod 21 and the eccentric rod 30 are covered inside the swing cover 40 (see reference). Figure 2 ).

[0034] In the above structure, when the swing end of the eccentric rod 30 moves from being vertical to the front of the fixed bracket 10 to approaching the front of the fixed bracket 10, the eccentric structure at the hinge position pulls the pull rod 21 to reach or pass the dead point position. When it reaches or passes the dead point position, the reverse pulling force of the pull rod 21 will cause the side of the eccentric rod 30 to abut against the front of the fixed bracket 10. Therefore, when the swing cover 40 is set at the end of the eccentric rod 30, it can be ensured that the swing cover 40 also approaches or abuts against the front of the fixed bracket 10. The swing cover 40 is used to cover the eccentric rod 30 and the pull rod 21, so that it is no different from the knob structure in appearance, ensuring the overall aesthetics and the simplicity of the structure. When disassembly is required, simply pull the swing cover 40 away from the front of the fixed bracket 10. At the same time, the swing cover 40 will also pull the eccentric rod 30 away from the front of the fixed bracket 10, thereby releasing the pulling force on the pull rod 21 and releasing the negative pressure on the suction cup 20.

[0035] In this embodiment, the eccentric rods 30 are two parallel rods spaced apart from each other, and the two eccentric rods 30 are connected by a crossbeam 31; the end of the pull rod 21 is hinged between the two eccentric rods 30; the other end of the two eccentric rods 30 is hinged to the swing cover 40.

[0036] In the above structure, the eccentric rod 30 consists of two cooperating crossbeams 31, which can effectively improve the hinge rigidity between the eccentric rod 30, the tie rod 21, and the swing cover 40.

[0037] In this embodiment, the two eccentric rods 30 are provided with a protruding quick-release pin 32 on the side of their ends facing each other or away from each other away from the pull rod 21; the swing cover 40 is provided with a quick-release buckle 41 that is adapted to and hinged to the quick-release pin 32.

[0038] In the above structure, the eccentric rod 30 and the tie rod 21 are first hinged together by the hinge pin 50, so sufficient assembly space needs to be reserved; the quick-release pin 32 and the quick-release buckle 41 can be directly connected by snap-fit ​​in the later stage of assembly to ensure the reliability of the assembly process.

[0039] In this embodiment, the quick-release buckle 41 consists of two spaced elastic ribs 42 connected to the back of the swing cover 40. The elastic ribs 42 are provided with quick-release holes 421 for fitting with the quick-release pins 32. The outer edge of the side of the elastic ribs 42 facing the eccentric rod 30 where the quick-release pins 32 are located is provided with a guide slope 422. When the quick-release pins 32 are inserted, their ends fit with the guide slope 422, causing the elastic ribs 42 to undergo elastic deformation, which in turn causes the quick-release pins 32 to engage with the quick-release holes 421.

[0040] In the above structure, the quick-release pin 32 is engaged by guiding the elastic deformation of the inclined surface 422 and the elastic rib plate 42, and the hinge function is achieved after engagement while preventing disengagement.

[0041] In this embodiment, a misalignment prevention mechanism is provided between the fixed bracket 10 and the swing cover 40 to prevent the swing cover 40 from being misaligned when it approaches or abuts against the fixed bracket 10.

[0042] In the above structure, since the swing cover 40 is connected to the pull rod 21 through the eccentric rod 30, there is a risk of misalignment. The anti-misalignment mechanism can effectively stabilize the swing cover 40 after it is fastened.

[0043] In this embodiment, the error prevention mechanism includes two sets of quick-release buckles 41 spaced 180 degrees apart along the circumferential direction of the swing cover 40, and a positioning protrusion 12 on the front of the fixed bracket 10; when the swing cover 40 is fastened to the front of the fixed bracket 10, one set of quick-release buckles 41 is hinged to the eccentric rod 30, and the other set of quick-release buckles 41 is engaged with the positioning protrusion 12.

[0044] In the above structure, the quick-release buckle 41 is set at 180-degree intervals along the circumferential direction of the swing cover 40. At any 180-degree position, it can be hinged with the eccentric rod 30, and at the same time, the quick-release buckle 41 on the other side can be engaged with the positioning protrusion 12, thereby improving assembly efficiency.

[0045] In this embodiment, the end of the pull rod 21 is hinged to the eccentric rod 30 by a hinge pin 50.

[0046] In the above structure, the stability under stress can be ensured by hinge pin 50.
