Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a clip with adjustable opening and closing angles. Background Art

[0002] The clip is composed of two sets of clips and a spring. The clips are opened and closed by the connection of the hinge. In daily life, the clip is a common kitchen tool, which is often used to pick up food, such as bread, salad, noodles, etc.

[0003] However, when the clip is not working, the two groups of clips are always in an open state under the elastic force of the spring, which is not convenient for storage. In order to solve the above technical problems, in the prior art, a Chinese utility model patent with publication number CN202086195U discloses a food clip, including a pair of metal clips hingedly connected by a spring and a pin shaft, which are divided into an inner clip and an outer clip according to the position of the hinge ears of the clip hinges. A pair of pin holes are provided on the hinge ears of the inner clip, and a pair of longitudinal slots are provided above the pin holes, and a sliding lock is placed between the two slots; a pair of pin holes are provided on the hinge ears of the outer clip, and a card top is provided above the back of the outer clip, corresponding to the sliding lock provided on the inner clip, so that the food clip can be folded in a non-working state for easy storage;

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: since only the two sets of clips can be adjusted to open and close, when using the clips to clamp objects of different shapes and sizes, the user cannot adjust the opening and closing angles of the clips according to actual needs, which makes the clamping process not smooth enough and may even cause the object to slip, resulting in a poor user experience; in addition, the opening and closing stroke of the existing clips is fixed. In order to be able to clamp larger objects, the opening and closing angles of the clips adopt a design that is compatible with a large opening and closing angle. This design makes the front part of the clip become an invalid empty stroke when clamping smaller objects, requiring more clamping time and force, reducing the clamping efficiency and making the operation inconvenient.

[0035] Example: Figure 1-10 As shown, a clip with adjustable opening and closing angle comprises an elastic member 1, a rotating shaft 2, and two groups of clips 3. One end of the two groups of clips 3 is hinged by the rotating shaft 2 to form a clamping space 303. The elastic member 1 is assembled between the two groups of clips 3 to make the two groups of clips 3 move away from each other. It also comprises an adjusting member 4, one group of clips 3 is provided with a clamping portion 3021, the adjusting member 4 is rotatably assembled with the rotating shaft 2 and is used to rotate the other group of clips 3, the adjusting member 4 is provided with a clamping tooth 401 for clamping with the clamping portion 3021, and the clamping tooth 401 is provided with multiple groups. When in use, the adjusting member 4 is rotated to drive the clips 3 to rotate, and the clamping portion is respectively clamped with the multiple groups of clamping teeth 401, thereby realizing the adjustment of the opening and closing angle between the two groups of clips 3, changing the size of the clamping space 303, and adjusting the opening and closing angle. The adjustable degree design enables the clamp to adapt to objects of different sizes and shapes, improving the versatility and applicability of the clamp, so as to adapt to the needs of clamping different objects, such as bread, salad, noodles, etc. Since the clamp product is more applicable, it can cover a wider market and user groups, which helps to increase product sales. Secondly, for users of different age groups and usage habits, users can adjust the opening and closing angles of the clamp 3 according to actual needs, which reduces the empty stroke when clamping small objects, improves the clamping efficiency, makes the operation smoother, and improves the user satisfaction, which helps to improve the competitiveness of the product in the market. Furthermore, by rotating the adjustment part 4 to change the opening and closing angles of the two sets of clamps 3, the operation steps are simplified, the operation difficulty is reduced, and the operation convenience is increased.

[0036] The elastic member 1 in the prior art is a torsion spring, which is arranged at the hinge of the two groups of clips 3, and the rotating shaft 2 is passed through the inner circle of the torsion spring. The two groups of torsion arms of the torsion spring are respectively abutted against the inner walls of the two groups of clips 3, thereby realizing the opening and resetting of the two groups of clips 3. However, in this embodiment, since an adjusting member 4 is provided and assembled at the hinge of the two groups of clips 3, in order to solve the assembly problem of the elastic member 1, the elastic member 1 is an arc-shaped spring piece, and the two ends of the arc-shaped spring piece are respectively abutted against the inner walls of the two groups of clips 3, and the arc-shaped spring piece is spaced apart from the rotating shaft 2. The arc-shaped spring piece is used as the elastic member 1. Compared with the torsion spring, the assembly structure is simpler, the inner wall space of the clip 3 is reasonably utilized, and the risk of interference between the elastic member 1 and the adjusting member 4 is avoided.

[0037] In terms of the specific structure of the assembly of the adjusting member 4 and the rotating shaft 2, a rotating groove 402 is provided on the top wall of the adjusting member 4, the rotating shaft 2 is rotatably assembled with the inner wall of the rotating groove 402, a plurality of groups of engaging teeth 401 are arranged concentrically with the rotating shaft 2, the rotation center of the adjusting member 4 coincides with the hinge of the clip 3, when the adjusting member 4 is rotated, the smoothness of the engaging teeth 401 and the engaging portion 3021 is improved, the smoothness of the rotating adjustment of the adjusting member 4 is improved, and the resistance during operation is reduced. Specifically, the rotating groove 402 is arranged in a U shape.

[0038] In terms of the specific arrangement of the multiple groups of engaging teeth 401, the multiple groups of engaging teeth 401 are arranged on the bottom wall of the adjusting member 4 at equal angles with the axis of the rotating shaft 2 as the center, ensuring the precise control of the opening and closing angles of the clips 3 during the adjustment process, thereby improving the adjustment accuracy of the adjusting member 4 on the opening and closing angles of the two groups of clips 3.

[0039] When the adjusting piece 4 has completed adjusting the angles of the two groups of clips 3, in order to facilitate the clamping and opening of the two groups of clips 3, the adjusting piece 4 is provided with an elastic space 403. One side wall of the adjusting piece 4 is arranged to penetrate toward the other side wall to form the elastic space 403. The setting of the elastic space 403 enables the two groups of clips 3 to clamp and open more flexibly after the adjusting piece 4 completes the angle adjustment to adapt to different clamping requirements. Secondly, the clip 3 is deformed in the elastic space 403 of the adjusting piece 4 by squeezing the adjusting piece 4, thereby allowing the clip 3 to move freely within a certain range, reducing the operating torque that the user needs to apply when clamping an object, making the operation easier. Furthermore, the elastic space 403 can absorb and disperse the tiny vibrations in the clamping process, improve the stability of the clamped object, and prevent the clamped object from sliding or falling off.

[0040] The force of the clip 3 is transmitted to the elastic space 403 in the adjusting member 4. In order to facilitate the elastic space 403 to be deformed more easily, a connecting port 404 is opened on the side wall of the adjusting member 4 facing the elastic member 1. The connecting port 404 is connected to the elastic space 403. The setting of the connecting port 404 makes it easier for the elastic space 403 to be deformed when the adjusting member 4 is subjected to the force of the clip 3, thereby reducing the internal pressure of the adjusting member 4 during the deformation process, reducing the user's operating resistance, and making the clamping process more labor-saving. Secondly, the connecting port 404 helps the elastic space 403 to quickly return to its original state after the pressure is released, thereby keeping the two sets of clips 3 in an open state.

[0041] In order to improve the stability of the elastic space 403 , the adjusting member 4 is provided with a reinforcing rib connected to an inner wall of the elastic space 403 .

[0042] In order to facilitate the user to rotate the adjustment member 4 to adjust the opening and closing angles of the two groups of clips 3, the adjustment member 4 has a protruding shift block 405, and the shift block 405 is exposed on the two groups of clips 3. The design of the shift block 405 provides an obvious grip, so that the user can more easily hold and rotate the adjustment member 4, thereby adjusting the opening and closing angles of the clips 3, thereby improving the convenience of adjustment.

[0043] In order to facilitate hanging the clip, the dial block 405 is provided with a through hole 4051. When the clip is not needed, the clip can be hung on the hook through the through hole 4051, which is convenient for storing the clip.

[0044] In order to improve the stability of the hinge connection of the two groups of clips 3, the two groups of clips 3 are respectively a first clip 301 and a second clip 302. The first clip 301 is provided with a first flange portion 3011, and the second clip 302 is provided with a second flange portion 3022. The first flange portion 3011 is located on the inner side of the second flange portion 3022. The rotating shaft 2 is penetrated by the first flange portion 3011 and the second flange portion 3022, so that the first clip 301 and the second clip 302 are hinged. Through the assembly of the first flange portion 3011 and the second flange portion 3022, the risk of the two groups of clips 3 moving axially along the rotating shaft 2 is reduced, the stability of the hinge connection of the two groups of clips 3 is improved, the connection stability between the two groups of clips 3 is enhanced, and the risk of relative movement of the clips 3 during the clamping process is reduced, ensuring that the overall structure of the clip is more stable, making it more reliable when clamping objects and reducing the possibility of objects slipping.

[0045] Specifically, in terms of the structure of the assembly of the first clip 301 and the shaft 2, the first flange portion 3011 is provided with an L-shaped long groove 3012, and the long groove 3012 is connected to the bottom wall of the first flange portion 3011 to form an opening, and the shaft 2 is connected to the second flange portion 3022. During assembly, the opening of the first clip 301 is aligned with the shaft 2 for assembly, and moves along the inner wall of the long groove 3012, so that the shaft 2 is clamped at the bend of the long groove 3012, thereby completing the assembly of the first clip 301 and the second clip 302, reducing the difficulty of assembly and improving assembly efficiency.

[0046] In terms of the specific structure of the adjusting member 4 and the specific arrangement position of the locking portion 3021, the top wall of the adjusting member 4 is provided with a recessed portion 406 which is recessed from top to bottom, and the outer wall of the recessed portion 406 is matched with the inner wall of the first flange portion 3011. The locking portion 3021 is arranged on the inner bottom wall of the second clamp 302. The arrangement of the recessed portion 406 makes the adjusting member 4 fit tightly with the first flange portion 3011, thereby improving the assembly stability between the adjusting member 4 and the clamp 3 and reducing the risk of the adjusting member 4 falling off during use. By improving the stability of the assembly of the adjusting member 4 and the clamp 3, the risk of clamp clamping failure caused by loosening or falling off of the adjusting member 4 is reduced.

[0047] Furthermore, in order to improve the smoothness of adjustment of the adjusting member 4 , the locking portion 3021 is configured as an arc-shaped protrusion, and the inner wall of the locking tooth is adapted to the outer wall of the locking portion 3021 and is also configured as an arc-shaped protrusion.

[0048] In terms of the specific installation structure of the arc-shaped spring piece, the present embodiment also includes a first pressure rod 5 and a second pressure rod 6. The first pressure rod 5 is assembled with the first flange portion 3011 and is used to compress one end of the arc-shaped spring piece, and the second pressure rod 6 is assembled with the second flange portion 3022 and is used to compress the other end of the arc-shaped spring piece. The arrangement of the first pressure rod 5 and the second pressure rod 6 can effectively compress the two ends of the arc-shaped spring piece, ensuring that the spring piece remains fixed during the assembly process and is not easily displaced, and ensuring that after the clamping action is completed, the spring piece can be quickly reset to maintain normal use of the clamp.

[0049] Furthermore, in order to improve the stability of the arc-shaped spring piece assembly, a first bending portion 101 is provided at one end of the arc-shaped spring piece, and the opening of the first bending portion 101 is arranged toward the first pressure rod 5, and the first pressure rod 5 is located above the first bending portion 101; a second bending portion 102 is provided at the other end of the arc-shaped spring piece, and the opening of the second bending portion 102 is arranged toward the second pressure rod 6, and the second pressure rod 6 is located above the second bending portion 102, the first pressure rod 5 is arranged close to the rotating shaft 2, and the second pressure rod 6 is arranged away from the rotating shaft 2.

[0050] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application.
