Description

Technical Field

[0001] This utility model relates to the field of hook technology, specifically to a simple hook device. Background Technology

[0002] Hook devices are a common structure with a wide range of applications. With the development of the automotive industry, people have increasingly higher requirements for the practicality, comfort, and aesthetics of car interiors, and hook devices have become an integral part of car interiors, facilitating the hanging and retrieval of passengers' belongings. With technological innovation and iteration, hook devices have evolved to include rotary hook devices that allow the hook body to be in an open or retracted state. However, existing rotary hook devices are not perfect. Firstly, when the hook body is in the retracted or open state, it may rotate in the opposite direction due to its own weight, lacking an anti-rotation positioning mechanism. Secondly, when the hook body is subjected to force, the rotation axis of the hook body will exert an axial force on the base (shell), making the hook body prone to detachment under force. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a simple hook device that ensures the hook body can be stably positioned and prevented from rotating in both the stored and open states. It also prevents the hook body from being stretched and deformed due to excessive force on one side, thereby improving the device's resistance to torsion.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A simple hook device, comprising:

[0006] The base has a hook connecting part on its inner side, and a first stop part and a second stop part are arranged sequentially in a counterclockwise direction on the outer periphery of the hook connecting part. The hook connecting part has a connecting port.

[0007] The hook body is rotatably connected to the connecting port via an outer rotating shaft. An anti-rotation body is provided on the outer side of the hook body. When the hook body is in the retracted state, the anti-rotation body forms an anti-rotation limiting contact with the first stop part. When the hook body is in the open state, the anti-rotation body forms an anti-rotation limiting contact with the second stop part.

[0008] Furthermore, a lateral stop is provided on the upper edge of the inner side of the base, and a lateral stop is provided on the outer side of the hook to cooperate with the lateral stop. When the hook is rotated counterclockwise to the open state, the hook contacts the upper edge surface of the inner side of the base, and the lateral stop and the lateral stop form a lateral limiting cooperation.

[0009] Furthermore, the anti-rotation part and the arc part are arranged sequentially in a clockwise direction on the outer periphery of the anti-rotation body; when the hook body is in the retracted state, the arc part forms an anti-rotation limiting contact with the first stop part, and the anti-rotation part forms a surface contact with the upper edge of the inner side of the base; when the hook body is in the open state, the arc part forms an anti-rotation limiting contact with the second stop part.

[0010] Furthermore, the areas where the first and second stop portions contact the arc portion are arc surfaces, while the anti-rotation portion is a plane.

[0011] Furthermore, the length of the rotating shaft protrudes beyond the connection port, or the length of the rotating shaft is level with the connection port, to prevent the rotating shaft from detaching.

[0012] Furthermore, the hook body has a raised portion for its hanging part.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] A simple hook device is provided, including a base and a hook rotatably connected to the base. Through the setting of a first stop and a second stop, combined with the limiting contact of an anti-rotation body, anti-rotation positioning is achieved in both the retracted and open states, ensuring stable anti-rotation positioning of the hook in both states and preventing accidental rotation due to the hook's own weight. In the open state, the hook contacts the upper edge of the inner side of the base, increasing the contact area between the hook and the base, effectively distributing the suspension load. Furthermore, the cooperation of the lateral stop and the lateral stop body prevents the hook from being stretched and deformed by excessive force on one side, and also effectively prevents the hook from deforming and detaching due to excessive force on one side, significantly improving the device's resistance to torsion.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figure 1-7 As shown, this utility model provides a technical solution: a simple hook device, comprising: a base 1, with a hook connecting part 10 disposed on the inner side of the base 1, and a first stop part 11 and a second stop part 12 arranged sequentially in a counterclockwise direction on the outer periphery of the hook connecting part 10, and a connection port 100; a hook 2, which is rotatably connected to the connection port 100 via an outer rotating shaft 20, and an anti-rotation body 21 disposed on the outer side of the hook 2. When the hook 2 is in the retracted state, the anti-rotation body 21 forms an anti-rotation limiting contact with the first stop part 11; when the hook 2 is in the open state, the anti-rotation body 21 forms an anti-rotation limiting contact with the second stop part 12. Through the arrangement of the first stop part 11 and the second stop part 12, combined with the limiting contact of the anti-rotation body 21, anti-rotation positioning is achieved in both the retracted and open states, ensuring that the hook 2 can be stably anti-rotated in both the retracted and open states, preventing accidental rotation due to the weight of the hook 2. It should be noted that: when the hook body 2 is to be rotated counterclockwise to the open state, applying force to the hook body 2 will cause the anti-rotation body 21 to disengage from the first stop part 11; when the hook body 2 is to be rotated clockwise to the retracted state, applying force to the hook body 2 will cause the anti-rotation body 21 to disengage from the second stop part 12.

[0025] See Figures 3-7A lateral stop 13 is provided on the upper edge of the inner side of the base 1, and a lateral stop 22 is provided on the outer side of the hook 2 to cooperate with the lateral stop 13. When the hook 2 is rotated counterclockwise to the open state, the hook 2 contacts the upper edge surface of the inner side of the base 1, and the lateral stop 22 and the lateral stop 13 form a lateral limiting cooperation. When the hook 2 is in the open state, the hook 2 contacts the upper edge surface of the inner side of the base 1, increasing the contact area between the hook and the base 1, effectively dispersing the suspension load. The cooperation between the lateral stop 13 and the lateral stop 22 prevents the hook 2 from being stretched and deformed by excessive force on one side, and also effectively prevents the hook 2 from deforming and detaching due to excessive force on one side, significantly improving the device's anti-torsion ability.

[0026] See Figures 3-7 The anti-rotation body 21 has an anti-rotation portion 210 and an arc portion 211 arranged sequentially in a clockwise direction on its outer periphery. When the hook 2 is in the retracted state, the arc portion 211 forms an anti-rotation limiting contact with the first stop portion 11, and the anti-rotation portion 210 forms a surface contact with the upper edge of the inner side of the base 1. When the hook 2 is in the open state, the arc portion 211 forms an anti-rotation limiting contact with the second stop portion 12. The areas where the first stop portion 11 and the second stop portion 12 contact the arc portion 211 are arc surfaces, while the anti-rotation portion 210 is a plane. The arc surface contact design between the arc portion 211 and the stop portion provides rolling friction during the rotation of the hook 2, resulting in less frictional resistance compared to traditional planar friction, making the retracting / opening operation smoother. After the plane of the anti-rotation portion 210 contacts the upper edge of the base 1, it forms a large-area frictional support, increasing the frictional resistance in the static state and further improving the stable anti-rotation positioning in the retracted state.

[0027] The length of the rotating shaft 20 protrudes beyond the connection port 100, or the length of the rotating shaft 20 is flush with the connection port 100, to prevent the rotating shaft 20 from disengaging. The design of the rotating shaft 20 being flush with or extending beyond the connection port 100 forms an axial self-locking mechanism through physical dimension matching, preventing the rotating shaft 20 from disengaging without additional snap-fit ​​parts, thus simplifying maintenance costs.

[0028] See Figures 4-5 The hook body 2 has a raised portion 230 on its hanging body 23. The raised portion 230 is designed to prevent items from falling off the hanging body 23.

[0029] In use, when the hook 2 is to be rotated counterclockwise to the open position, applying force to the hook 2 will cause the arc portion 211 on the anti-rotation body 21 to disengage from the first stop portion 11; simultaneously, the hook 2 will contact the upper edge surface of the inner side of the base 1, and the arc portion 211 on the anti-rotation body 21 will form an anti-rotation limiting contact with the second stop portion 12. When the hook 2 is to be rotated clockwise to the retracted position, applying force to the hook 2 will cause the arc portion 211 on the anti-rotation body 21 to disengage from the second stop portion 12; simultaneously, the arc portion 211 on the anti-rotation body 21 will form an anti-rotation limiting contact with the first stop portion 11, and the anti-rotation portion 210 will form a surface contact with the upper edge of the inner side of the base 1.
