Description

Technical Field

[0001] This application belongs to the field of daily necessities, and specifically relates to a clamping device. Background Technology

[0002] In daily cooking or serving, the problem of transferring tableware that is too hot is often encountered. Therefore, tableware tongs were developed to transfer hot tableware. They are hygienic, convenient, and effectively protect hands from injury, making them popular with consumers. However, most tableware tongs on the market currently use a single-handed operation design where the thumb and four fingers hold the two arms separately. This structure has limitations when handling larger diameter tableware. The limited grip span makes it difficult to stably hold the arms with one hand, preventing one-handed operation. Furthermore, the limited grip span results in insufficient clamping force, causing tableware to wobble and fall during transfer, potentially leading to tableware breakage, food spillage, or even burns from falling hot tableware, causing significant inconvenience and threats to users. Utility Model Content

[0003] In view of this, it is necessary to provide a new clamping device to solve the above problems.

[0004] Some embodiments of this application provide a clamping device, including a first clamping arm, a second clamping arm rotatably connected to the first clamping arm, and an auxiliary arm. The auxiliary arm is located between the first clamping arm and the second clamping arm and is rotatably connected to the first clamping arm. The angle at which the auxiliary arm can open relative to the first clamping arm is smaller than the angle at which the second clamping arm can open relative to the first clamping arm.

[0005] In some embodiments, the clamping device further includes an elastic portion connected between the auxiliary arm and the first clamping arm.

[0006] In some embodiments, the clamping device further includes a limiting portion and a mating portion cooperating with the limiting portion, one of the limiting portion and the mating portion being disposed on the auxiliary arm, and the other of the limiting portion and the mating portion being disposed on the first clamping arm, the limiting portion being arranged to abut against the mating portion when the auxiliary arm and the first clamping arm are opened relative to each other.

[0007] In some embodiments, the clamping device further includes an elastic portion connected between the auxiliary arm and the first clamping arm.

[0008] In some embodiments, the first clamping arm extends outward to form a first extension arm, and the second clamping arm extends outward to form a second extension arm, wherein the length of the first extension arm is less than that of the first clamping arm, and the length of the second extension arm is less than that of the second clamping arm.

[0009] In some embodiments, the first clamping arm includes a first annular connecting end and a first clamping arm body, the first annular connecting end being connected between the first extension arm and the first clamping arm body; the second clamping arm includes a second annular connecting end and a second clamping arm body, the second annular connecting end being connected between the second extension arm and the second clamping arm body; the first annular connecting end and the second annular connecting end are rotatably connected and at least partially overlap.

[0010] In some embodiments, the clamping device further includes a connector that connects the first annular connecting end and the second annular connecting end, such that the first annular connecting end and the second annular connecting end are rotatably connected.

[0011] In some embodiments, the connector includes a first connecting ring, a first side plate connected to the outer periphery of the first connecting ring, a second connecting ring, and a second side plate connected to the outer periphery of the second connecting ring. The first connecting ring is connected to the second connecting ring, and the first side plate and the second side plate are disposed opposite to each other. The first annular connecting end and the second annular connecting end are both sleeved on the first connecting ring and the second connecting ring that are connected together, and are located between the first side plate and the second side plate.

[0012] In some embodiments, the clamping device further includes a locking part and a fastening part that cooperates with the locking part, one of the locking part and the fastening part being disposed on the first clamping arm, and the other of the locking part and the fastening part being disposed on the second clamping arm.

[0013] In some embodiments, the first clamping arm and / or the second clamping arm have a receiving groove on the side facing the auxiliary arm, and the auxiliary arm can be received in the receiving groove.

[0014] In summary, the clamping device in this application, through the cooperative design of the auxiliary arm, the first clamping arm, and the second clamping arm, enables the clamping device to be used by holding the auxiliary arm and the second clamping arm with one hand, replacing the traditional method of holding the first clamping arm and the second clamping arm. This shortens the hand grip span for single-handed operation of the clamping device and breaks the limitation of being unable to clamp large-sized tableware with one hand due to the limited hand grip span. In addition, by controlling the clamping with the auxiliary arm, the clamping force can be controlled more precisely, effectively avoiding insufficient clamping force that causes the tableware to shake or fall off during transfer, thereby preventing safety accidents such as tableware breakage, food spillage, or even hot tableware falling and causing burns. At the same time, it improves the stability of the tableware during transfer, making the user experience more reliable and reassuring. Attached Figure Description

Detailed Implementation

[0022] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0023] Please see Figures 1 to 4This application provides a clamping device 1 in some embodiments, including a first clamping arm 10, a second clamping arm 20, and an auxiliary arm 30. The first clamping arm 10 is rotatably connected to the second clamping arm 20. The auxiliary arm 30 is located between the first clamping arm 10 and the second clamping arm 20 and is rotatably connected to the first clamping arm 10. The angle at which the auxiliary arm 30 can open relative to the first clamping arm 10 is smaller than the angle at which the second clamping arm 20 can open relative to the first clamping arm 10. Thus, when it is necessary to use the clamping device 1 to clamp tableware, the first clamping arm 10 is opened relative to the second clamping arm 20 to the required size of the tableware, and at the same time, the auxiliary arm 30 is opened relative to the first clamping arm 10. Because the angle at which the auxiliary arm 30 can open relative to the first clamping arm 10 is smaller than the angle at which the second clamping arm 20 can open relative to the first clamping arm 10, when the user simultaneously grips the second clamping arm 20 and the auxiliary arm 30 with one hand and applies force, the force is limited by the auxiliary arm 30. The angle between the auxiliary arm 30 and the first clamping arm 10 is locked after the auxiliary arm 30 is opened to a predetermined position. When the user continues to apply pressure, the auxiliary arm 30 will move the first clamping arm 10 connected to it toward the second clamping arm 20 under the action of continuous force, so that the first clamping arm 10 and the second clamping arm 20 cooperate to clamp the tableware. After the clamping device 1 is used, the first clamping arm 10 and the second clamping arm 20 are closed together, and the auxiliary arm 30 is also stored between the first clamping arm 10 and the second clamping arm 20.

[0024] Therefore, it can be seen that the clamping device 1 in some embodiments of this application, through the cooperative design of the auxiliary arm 30, the first clamping arm 10 and the second clamping arm 20, enables the clamping device 1 to achieve clamping by holding the auxiliary arm 30 and the second clamping arm 20 with one hand, replacing the traditional method of holding the first clamping arm 10 and the second clamping arm 20. This shortens the hand grip span of the clamping device 1 and breaks the limitation of being unable to complete the operation of clamping large-sized tableware with one hand due to the limitation of the hand grip span. In addition, by controlling the clamping through the auxiliary arm 30, the clamping force can be controlled more precisely, effectively avoiding insufficient clamping force causing the tableware to shake or fall off during transfer, thereby causing tableware damage, food spillage, or even safety accidents caused by hot tableware falling and burning. At the same time, it improves the stability of the tableware transfer process, making the user experience more reliable and reassuring.

[0025] In some implementations, the reference Figure 3 and Figure 4The clamping device 1 also includes an elastic part 40. The elastic part 40 is connected between the auxiliary arm 30 and the first clamping arm 10. When the first clamping arm 10 and the second clamping arm 20 are opened, the auxiliary arm 30 automatically pops out relative to the first clamping arm 10, so as to facilitate the user to hold the auxiliary arm 30. At the same time, it also limits the opening angle of the auxiliary arm 30 relative to the first clamping arm 10 to a certain extent, so as to ensure that the auxiliary arm 30 cooperates with the second clamping arm 20 to achieve clamping. It is understandable that after the clamping device 1 is used, the first clamping arm 10 and the second clamping arm 20 are retracted towards each other, and the auxiliary arm 30 is also stored between the first clamping arm 10 and the second clamping arm 20. At this time, the elastic part 40 is compressed between the auxiliary arm 30 and the first clamping arm 10 to obtain elastic potential energy. When the clamping device 1 is needed to clamp the tableware, the first clamping arm 10 opens relative to the second clamping arm 20, and the elastic part 40 releases elastic potential energy to push the auxiliary arm 30 to rotate towards the second clamping arm 20, so that the user can hold the auxiliary arm 30 more firmly to cooperate with the second clamping arm 20 for clamping.

[0026] The elastic part 40 is not limited to elastic rubber, spring, sheet, torsion spring and other structures, and is not restricted here.

[0027] Furthermore, in some implementations, the reference Figure 3 and Figure 4 The first clamping arm 10 has a groove 11 on the side facing the auxiliary arm 30, and the auxiliary arm 30 has a protrusion 31 on the side facing the first clamping arm 10. One end of the elastic part 40 is received in the groove 11, and the other end of the elastic part 40 is provided on the protrusion 31 to limit the position of the elastic part 40 and prevent the elastic part 40 from being displaced during use and affecting the normal use of the clamping device 1. The protrusion 31 and the groove 11 can be interchanged. Of course, in some other embodiments, the elastic part 40 is not limited to being limited by the cooperation of the protrusion 31 and the groove 11, but can also be limited by structures such as screws and buckles, which are not limited here.

[0028] Of course, in some other embodiments, the elastic part 40 may be omitted.

[0029] In some implementations, the reference Figure 3 and Figure 4 The clamping device 1 also includes a limiting part 51 and a mating part 52 that cooperates with the limiting part 51. One of the limiting part 51 and the mating part 52 is disposed on the auxiliary arm 30, and the other of the limiting part 51 and the mating part 52 is disposed on the first clamping arm 10. The limiting part 51 abuts against the mating part 52 when the auxiliary arm 30 and the first clamping arm 10 are opened relative to each other, limiting the opening angle of the auxiliary arm 30 relative to the first clamping arm 10, and ensuring that the auxiliary arm 30 and the second clamping arm 20 work together to achieve the clamping operation.

[0030] In this embodiment, the reference Figure 3 and Figure 4 The limiting part 51 is disposed on the side of the first clamping arm 10 facing the auxiliary arm 30, and the mating part 52 extends outward from the end of the auxiliary arm 30. When the clamping device 1 is in use, the first clamping arm 10 opens relative to the second clamping arm 20, and the auxiliary arm 30 opens relative to the first clamping arm 10. When the user simultaneously grips the auxiliary arm 30 and the second clamping arm 20 with one hand and applies force, the auxiliary arm 30 will rotate relative to the first clamping arm 10 towards the second clamping arm 20. The mating part 52 on the auxiliary arm 30 will then rotate along with the auxiliary arm 30 to abut against the limiting part 51 (e.g., ...). Figure 3 As shown), the auxiliary arm 30 opens to a predetermined position relative to the first clamping arm 10. If the user continues to apply force to the auxiliary arm 30 and the second clamping arm 20, the auxiliary arm 30, due to the restriction of the engaging part 52 and the limiting part 51, can no longer rotate relative to the first clamping arm 10 towards the second clamping arm 20. Then, the force of the auxiliary arm 30 will cause the connected first clamping arm 10 to rotate towards the second clamping arm 20, so that the first clamping arm 10 and the second clamping arm 20 cooperate to achieve clamping. When the clamping device 1 is finished using, the first clamping arm 10 and the second clamping arm 20 are retracted towards each other, and the auxiliary arm 30 rotates towards the first clamping arm 10 to be stored between the first clamping arm 10 and the second clamping arm 20. Simultaneously, the engaging part 52 on the auxiliary arm 30 rotates along with the auxiliary arm 30 to release its contact with the limiting part 51 (e.g., ...). Figure 4 (As shown).

[0031] Of course, in some other embodiments, the mating part 52 is not limited to being provided at the end of the auxiliary arm 30, but may also be located at other positions such as the middle part that can perform a limiting function with the limiting part 51, which is not limited here.

[0032] In some implementations, the reference Figures 1 to 5 The first clamping arm 10 extends outward to form a first extension arm 61, and the second clamping arm 20 extends outward to form a second extension arm 62. The length of the first extension arm 61 is less than that of the first clamping arm 10, and the length of the second extension arm 62 is less than that of the second clamping arm 20.

[0033] Understandable, participants Figure 1 and Figure 3 The first clamping arm 10, the first extending arm 61, the second clamping arm 20, and the second extending arm 62 form an X-shaped structure. In this way, the operation of clamping tableware using the first extending arm 61 and the second extending arm 62 can be realized by controlling the first clamping arm 10 and the second clamping arm 20, so as to enrich the application scenarios of the clamping device 1 and make it adaptable to the clamping operation of tableware of various sizes.

[0034] In some implementations, the reference Figure 1 , Figure 5 and Figure 6 The first clamping arm 10 includes a first annular connecting end 101 and a first clamping arm body 102, with the first annular connecting end 101 connected between the first extension arm 61 and the first clamping arm body 102. The second clamping arm 20 includes a second annular connecting end 201 and a second clamping arm body 202, with the second annular connecting end 201 connected between the second extension arm 62 and the second clamping arm body 202. The first annular connecting end 101 and the second annular connecting end 201 are rotatably connected and at least partially overlap, so that the overlapping part can function as a hanging ring to hang and store the clamping device 1 when it is not in use.

[0035] In some implementations, the reference Figure 1 and Figure 6 The clamping device 1 also includes a connector 70. The connector 70 connects the first annular connecting end 101 and the second annular connecting end 201 so that the first annular connecting end 101 and the second annular connecting end 201 are rotatably connected.

[0036] Specifically, refer to Figure 1 , Figure 5 and Figure 6 The connector 70 includes a first connecting ring 701, a first side plate 702 connected to the outer periphery of the first connecting ring 701, a second connecting ring 703, and a second side plate 704 connected to the outer periphery of the second connecting ring 703. The first connecting ring 701 connects to the second connecting ring 703, and the first side plate 702 and the second side plate 704 are disposed opposite to each other. The first annular connecting end 101 and the second annular connecting end 201 are both sleeved on the connected first connecting ring 701 and the second connecting ring 703, and are located between the first side plate 702 and the second side plate 704. It can be understood that the connected first connecting ring 701 and the second connecting ring 703 not only assist in the rotational connection between the first clamping arm 10 and the second clamping arm 20, but also act as hanging rings to hang and store the clamping device 1 when it is not in use. The first side plate 702 and the second side plate 704 are used to define the position of the first annular connecting end 101 and the second annular connecting end 201 to prevent slippage during use.

[0037] In some implementations, the reference Figure 1 and Figure 2 The clamping device 1 also includes a locking part 81 and a fastening part 82 that cooperates with the locking part 81. One of the locking part 81 and the fastening part 82 is disposed on the first clamping arm 10, and the other of the locking part 81 and the fastening part 82 is disposed on the second clamping arm 20, so that when the clamping device 1 is in the storage state, the locking part 81 and the fastening part 82 fasten and lock the first clamping arm 10 and the second clamping arm 20, thereby reducing the storage volume of the clamping device 1 in the non-use state and reducing the pressure in the storage space.

[0038] In this embodiment, the locking part 81 is a slider that is slidably disposed on the second clamping arm 20; the fastening part 82 is a buckle that, when the first clamping arm 10 and the second clamping arm 20 are closed, slide the locking part 81 to the fastening part 82 to engage, thereby locking the first clamping arm 10 and the second clamping arm 20.

[0039] Of course, in some other embodiments, the locking part 81 can also be a buckle structure, and the fastening part 82 can be a protrusion or groove structure. That is, the specific structure of the locking part 81 and the fastening part 82 is not limited, as long as they can be fastened together to lock the first clamping arm 10 and the second clamping arm 20.

[0040] In some implementations, the reference Figure 4 The first clamping arm 10 and / or the second clamping arm 20 are provided with a receiving groove 12 on the side facing the auxiliary arm 30. When the clamping device 1 is in the storage state, the auxiliary arm 30 can be stored in the receiving groove 12, which ensures the overall aesthetics of the clamping device 1 and also protects the auxiliary arm 30 to a certain extent.

[0041] In this embodiment, the first clamping arm 10 and the second clamping arm 20 are respectively provided with receiving grooves 12 on the side facing the auxiliary arm 30.

[0042] Furthermore, participants Figure 2 and Figure 4 The clamping device 1 also includes an anti-slip pad 90, wherein the anti-slip pad 90 may be disposed as needed in the gripping area of ​​the first clamping arm 10 and the second clamping arm 20, or at the clamping end of the first clamping arm 10 and the second clamping arm 20, or at the clamping end of the first extension arm 61 and the second extension arm 62, and there is no specific limitation.

[0043] Of course, in some other implementations, the anti-slip pad 90 may be omitted.

[0044] The specific embodiments described herein are merely illustrative examples of the spirit of this application. Those skilled in the art to which this application pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this application or exceeding the scope defined by the appended claims.

[0045] Although this document uses a large number of technical terms, the possibility of using other terms is not excluded. These terms are used merely to facilitate the description and explanation of the nature of this application; interpreting them as any additional limitation would be contrary to the spirit of this application.
