Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchenware technology, and in particular to an automatic opening and closing food clip. Background Technology
[0002] Traditional food tongs open automatically with spring force after being released. This feature is inconvenient because the open arms take up a lot of space and may bump into surrounding objects when temporarily placing or storing food. To solve this problem, some food tongs on the market have manual locking mechanisms, which use additional latches or sliders to manually lock the arms in place. However, these locking mechanisms require manual operation by the user. During cooking, especially when frequent handling and temporary placement are needed, forgetting to lock or unlock can be inconvenient and lacks smooth operation. In addition, the arm length of existing food tongs is usually fixed, which cannot accommodate the needs of handling pots or containers of different depths, and the flexibility needs to be improved. Utility Model Content
[0003] The purpose of this invention is to provide an automatic opening and closing food clip designed to solve at least one technical problem in the background art.
[0004] To achieve the above objectives, this utility model adopts the following solution: an automatic opening and closing food clamp, comprising a first clamping arm and a second clamping arm, which are rotatably connected by a pivot structure; an elastic element disposed between the first clamping arm and the second clamping arm to provide an elastic force for opening the clamping arms; and a counterweight locking mechanism movably disposed between the first clamping arm and the second clamping arm; the counterweight locking mechanism has a first working position and a second working position; wherein, when the food clamp is in the first position, the counterweight locking mechanism moves to the first working position under the action of gravity, restricting the opening movement of the first clamping arm and the second clamping arm, so that the food clamp remains in a closed and locked state; when the food clamp is in the second position, the counterweight locking mechanism moves to the second working position under the action of gravity, restricting the opening angle of the first clamping arm and the second clamping arm, so that the food clamp remains in a ready-to-clamp state.
[0005] The advantages of this invention are as follows: By setting a counterweight locking mechanism, the food clamp automatically switches between a closed, locked state for easy storage and a ready-to-open state for easy grabbing using the principle of gravity. Users do not need to remember or perform any additional locking / unlocking actions; simply changing the orientation of the food clamp automatically completes the state transition, greatly improving operational intuitiveness and ease of use. Furthermore, the adjustable clamp arm design adapts to different usage scenarios, significantly enhancing the product's practicality and flexibility. Attached Figure Description

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] Please see Figure 1-7In one embodiment, an automatic food clamp includes a first clamping arm 100, a second clamping arm 200, a rotating shaft structure 300, an elastic element 400, and a counterweight locking mechanism 500. The first clamping arm 100 and the second clamping arm 200 are rotatably connected via a pivot structure 300. An elastic element 400 is disposed between the first clamping arm 100 and the second clamping arm 200 to provide an elastic force that opens them. A counterweight locking mechanism 500 is movably disposed between the first clamping arm 100 and the second clamping arm 200. The counterweight locking mechanism 500 has a first working position and a second working position. When the food clamp is in the first position, the counterweight locking mechanism 500 moves to the first working position under gravity, restricting the opening movement of the first clamping arm 100 and the second clamping arm 200, keeping the food clamp in a closed and locked state. When the food clamp is in the second position, the counterweight locking mechanism 500 moves to the second working position under gravity, restricting the opening angle of the first clamping arm 100 and the second clamping arm 200, keeping the food clamp in a ready-to-grab state. This basic structure automatically switches working states through gravity sensing, realizing intelligent operation of the food clamp and significantly improving ease of use.
[0021] In one embodiment, the counterweight locking mechanism 500 includes a counterweight block with an elongated guide groove 510. A rotating shaft structure 300 passes through the guide groove 510, allowing the counterweight block to slide relative to the rotating shaft structure 300 along the extension direction of the guide groove 510. This guide groove structure ensures that the counterweight block can move precisely along a predetermined path, achieving reliable switching of working states.
[0022] In one embodiment, the counterweight includes a main body 520 and at least one limiting portion 530 extending from the main body 520 to both sides. When the counterweight is in a first working position, the main body 520 abuts against the inner walls of the first clamping arm 100 and the second clamping arm 200. When the counterweight is in a second working position, the limiting portion 530 abuts against the inner walls of the first clamping arm 100 and the second clamping arm 200. This structure achieves stable maintenance of both closed locking and ready-to-open states through the cooperation of different parts of the counterweight with the clamping arms.
[0023] In one embodiment, the limiting part 530 has a trapezoidal cross-section, with guide ramps on both sides for contacting the inner wall of the clamping arm. The trapezoidal design allows the counterweight to smoothly interfere with and accurately position itself against the inner wall of the clamping arm during movement, reducing jamming.
[0024] In one embodiment, both the first clamping arm 100 and the second clamping arm 200 include a handle portion 600 and a clamping portion 700 slidably connected to the handle portion 600; a posture adjustment mechanism 800 is provided between the clamping portion 700 and the handle portion 600 for adjusting and locking the extension length of the clamping portion 700 relative to the handle portion 600. This adjustable structure allows the food clamp to adapt to containers of different depths, greatly expanding its application range.
[0025] In one embodiment, the pose adjustment mechanism 800 includes at least one protrusion 810 disposed on one of the clamping part 700 and the handle part 600, and a plurality of positioning parts 820 disposed on the other; the protrusion 810 can selectively cooperate with different positioning parts 820 to achieve locking of different lengths. This positioning structure is simple, reliable, and easy to adjust.
[0026] In one embodiment, the protrusion 810 is a cylindrical protrusion, and the positioning part 820 is a circular positioning hole. The fit between the cylinder and the circular hole provides a stable and reliable locking force, while the manufacturing process is simple and inexpensive.
[0027] In one embodiment, the counterweight is further provided with an extraction structure 540, which is a through hole formed on the counterweight and / or a bent portion provided on the top of the counterweight. This design facilitates the user to remove the counterweight from the clamping arm for cleaning or maintenance, improving the maintainability of the product.
[0028] In one embodiment, the elastic element 400 is a V-shaped torsion spring, with its two ends acting on the first clamping arm 100 and the second clamping arm 200, respectively. The V-shaped torsion spring can provide a uniform and stable opening force, and has a compact structure, making it easy to install.
[0029] In one embodiment, the first posture is a vertically placed state with the gripping end of the food tongs facing upwards and the handle end facing downwards; the second posture is a vertically placed state with the gripping end of the food tongs facing downwards and the handle end facing upwards. These two clearly defined working postures make the state switching intuitive and natural, conforming to the user's usage habits.
[0030] In one embodiment, the gripping end of the clamping part 700 is provided with anti-slip texture. This design enhances the friction when gripping food, prevents food from slipping, and improves the reliability of use.
[0031] In one embodiment, the first clamping arm 100 and the second clamping arm 200 are made of stainless steel. Stainless steel has excellent corrosion resistance and structural strength, ensuring the durability and hygiene of the product.
[0032] In one embodiment, the counterweight is made of a high-density metal. High-density materials can provide sufficient weight in a small volume, ensuring the counterweight can reliably move under gravity, making state switching more sensitive and reliable.
[0033] In one embodiment, the length of the guide groove 510 is greater than the diameter of the rotating shaft structure 300, and the length difference is the travel distance of the counterweight locking mechanism 500 between the first working position and the second working position. This travel distance design ensures that the counterweight can accurately switch between the two working positions, avoiding the generation of intermediate states.
[0034] In one embodiment, a plurality of positioning portions 820 are evenly distributed along the axial direction of the handle portion 600. This evenly distributed design allows for more precise length adjustment and provides multiple fixed effective clamping lengths to meet different usage requirements.
[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
