The reversible dual-function clamp designed in the application realizes the two functions of sealing and clamping through the reversible first arm and the second arm and the integrated elastic assembly. In the clamping state, the assembly abuts against each other to form a lever fulcrum, so that a traditional independent metal spring is replaced by an integrally formed structure, the structure is simplified, the cost is reduced, and the risk of spring rust or failure is avoided. Meanwhile, the elastic recovery force provided by the assembly can automatically open the clamping arms, and the clamping arms can be deflected outward when being excessively pressed, so that the overall clamp is protected from overload.

Description

Technical Field

[0001] This application relates to the field of daily necessities technology, and in particular to a reversible dual-function clamp. Background Technology

[0002] In daily life, clamps are widely used as a convenient auxiliary tool. One common type of clamp is the sealing clamp for food packaging bags. These clamps typically consist of two interlocking arms and a structure for connecting or locking the two arms. Their main function is to seal the opening of opened plastic bags, packaging bags, etc., through clamping force to prevent the contents from getting damp, spoiling, or scattering.

[0003] Existing sealing clips are designed to provide a reliable seal, and their structure is usually simple and their function is limited to sealing purposes. Utility Model Content

[0004] To address the aforementioned issues, this application provides a reversible dual-function clamp that enhances the versatility and durability of the product.

[0005] To achieve the above objectives, the present application designs a reversible dual-function fixture, comprising: Flexible part; A first arm and a second arm, the proximal ends of the first arm and the second arm being connected by the flexible portion, and the first arm and the second arm being able to rotate around the flexible portion to switch between a first state for sealing and a second state for clamping. An elastic component is disposed on the first arm and the second arm in a region adjacent to the flexible portion; When the clamp is in the second state, at least a portion of the elastic components abut against each other to form a fulcrum and provide an elastic restoring force that opens the first and second arms after they are compressed.

[0006] Preferably, the elastic component includes: The first cantilever is mounted on the first arm; The second cantilever is mounted on the second arm; In the first state, the first cantilever and the second cantilever are away from each other and do not contact each other; in the second state, the first cantilever and the second cantilever are in contact with each other.

[0007] Preferably, the first arm has a first cut for defining and accommodating the first cantilever, and the second arm has a second cut for defining and accommodating the second cantilever.

[0008] Preferably, when the clamp is compressed in the second state, the free ends of the first cantilever and the second cantilever can be elastically deflected to the outside of the first cut and the second cut, respectively.

[0009] Preferably, the free end of the first cantilever is provided with a first protrusion, and the free end of the second cantilever is provided with a second protrusion; in the second state, the first protrusion and the second protrusion abut against each other.

[0010] Preferably, a contact plane is provided at the position where the first protrusion and the second protrusion abut against each other.

[0011] Preferably, it further includes a locking mechanism for locking the distal ends of the first arm and the second arm together in the first state.

[0013] Preferably, the first arm, the second arm, the flexible part, and the elastic component are integrally formed.

[0014] The flip-up dual-function clamp designed in this application achieves both sealing and clamping functions in a single product by incorporating flip-up first and second arms and integrating elastic components. In the clamping state, these components abut against each other to form a lever fulcrum.

Detailed Implementation

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] like Figures 1 to 4 As shown in the figure, this embodiment describes a reversible dual-function clamp. The clamp mainly includes a flexible part 10, a first arm 20, and a second arm 30.

[0022] Specifically, both the first arm 20 and the second arm 30 are elongated strip structures, with their proximal ends integrally connected by the flexible part 10. The flexible part 10 utilizes the inherent toughness of the material to act as a reversible hinge, allowing the first arm 20 and the second arm 30 to rotate at large angles, thus switching between two different working states. In this embodiment, the clamp is preferably a one-piece molded plastic structure, for example, injection molded from materials with good elasticity and toughness such as polypropylene (PP) or polyethylene (PE). This ensures the durability and reliability of the flexible part 10, while also simplifying the production process and reducing manufacturing costs.

[0023] like Figure 1 As shown, when the clamp is in the first state, i.e., when used for sealing, the inner sides of the first arm 20 and the second arm 30 are in contact with each other, which can be used to clamp and seal the opening of the food packaging bag. To achieve reliable locking, as... Figure 1 , Figure 3 As shown, a buckle mechanism 60 is provided at the far end of the first arm 20 and the second arm 30, that is, at the end away from the flexible part 10. The buckle mechanism 60 includes a buckle 61 integrally formed on the first arm 20 and a buckle seat 62 integrally formed on the second arm 30 at a corresponding position. When in use, the bag opening is placed between the two arms and the far ends of the two arms are pressed. The buckle 61 will then snap into the buckle seat 62, thereby firmly locking the two arms together and achieving a sealing function.

[0024] like Figure 2 , Figure 4 As shown, the user can rotate the first arm 20 and the second arm 30 outwards about 360 degrees around the flexible part 10, turning the inner side of the two arms into the outer side, thereby switching to the second state, which is the clamping state. In this state, the clamp can be used as tweezers or food tongs to pick up small items such as snacks.

[0025] An elastic component 40 is provided on the first arm 20 and the second arm 30 in the region adjacent to the flexible part 10.

[0026] like Figure 1 , Figure 2 As shown, the elastic component 40 includes a first cantilever 41 disposed on the first arm 20 and a second cantilever 42 disposed on the second arm 30. To form these two cantilever arms, a first cutout 21 is correspondingly provided on the first arm 20, and a second cutout 31 is correspondingly provided on the second arm 30. These two cutouts not only define and accommodate the shape and size of the cantilever arms, but also provide the necessary space for the elastic deformation of the cantilever arms.

[0027] When the clamp is in such a position Figure 1 In the first state shown, the first cantilever 41 and the second cantilever 42 are respectively housed in their respective cuts, facing away from each other and not in contact.

[0028] And when the clamp is in such a position Figure 4 In the second state shown, the first cantilever 41 and the second cantilever 42 flip, and their free ends approach and abut against each other, thus forming a fulcrum 50 between the two arms. To achieve stable support and wear-resistant contact, the free end of the first cantilever 41 is provided with a first protrusion 411, and the free end of the second cantilever 42 is provided with a second protrusion 421. The abutting surfaces of the two protrusions are preferably set as flat contact planes 70.

[0029] In the second state of use, the user presses the distal or middle part of the first arm 20 and the second arm 30, and the two arms will perform lever movement around the fulcrum 50 formed by the contact plane 70, closing their front ends (distal ends) to grip the item. When the user releases their hand, due to the elasticity of the materials of the first cantilever 41 and the second cantilever 42, they will push against each other, generating an elastic restoring force. This restoring force will push the first arm 20 and the second arm 30 to automatically open, facilitating the next gripping. This integrated design completely replaces the traditional metal spring, avoiding the trouble of rusting, failure, and additional assembly.

[0030] Furthermore, the elastic component 40 also has an overload protection function. When the user applies excessive force during clamping, and the pressure applied to the first arm 20 and the second arm 30 is too great, the free ends of the first cantilever 41 and the second cantilever 42 will elastically deflect and move outwards from their respective first cuts 21 and second cuts 31, thereby releasing the excessive stress and effectively preventing the cantilever or arm body from breaking due to stress concentration, thus effectively improving the durability of the product.

[0031] In some embodiments, the first arm 20, the second arm 30, the flexible portion 10, and the elastic component 40 are integrally molded structures. This reduces weaknesses at material joints and facilitates cleaning.

[0032] The flip-up dual-function clamp provided in this application embodiment achieves both sealing and clamping functions in a single product by setting flip-up first and second arms and integrating elastic components. In the clamping state, the components abut against each other to form a lever fulcrum, replacing the traditional independent metal spring with an integrated molded structure, simplifying the structure, reducing manufacturing costs, and avoiding the risk of spring corrosion or failure. At the same time, the elastic restoring force provided by the component allows the clamping arms to automatically open and deflect outwards when excessively compressed, providing overload protection for the entire clamp and extending its service life.
