Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates preferred embodiments of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

According to a first aspect of the present invention, a buckle 20 is provided, as shown in fig. 1. The clip 20 may include a base 100, a plurality of clip portions 200, and a guide reinforcement portion 300.

The plurality of catching portions 200 may be spaced apart from each other along the predetermined direction X-X. A plurality of snap portions 200 may be provided on the base 100. In order to prevent the plastic member from shrinking after injection molding, each of the clamping portions 200 may be formed to be thin, for example, they have a substantially sheet shape. Typically, the plurality of clamping parts 200 can be parallel to each other. Each of the catching portions 200 may include a guide surface 202 and a catching surface 203. The guide surface 202 faces away from the substrate 100. The fastening surface 203 may be connected between the distal end 202b of the guide surface 202 and the base 100. The fastening surface 203 is parallel to the predetermined direction X-X. The guide surface 202 may extend obliquely toward the base 100 in a direction away from the fastening surface 203. Thus, the guide surface 202 may have a proximal end 202a proximal to the base 100 and a distal end 202b distal to the base 100. Typically, the guide surface 202 is an inclined plane, but in other embodiments, the guide surface may be curved. The fastening surface 203 may have various structures as long as it can fasten the adapted snap adapter 40, as shown in fig. 5. Fig. 6 shows a state where the buckle 20 and the buckle adapter 40 are disengaged, and when the buckle adapter 40 gets closer to the buckle 20 along the fastening direction (e.g., the vertical upward direction shown in fig. 6), the proximal end 202a of the guide surface 202 first comes into contact with the buckle adapter 40, and then the buckle adapter 40 moves along the guide surface 202 to the distal end 202b of the guide surface 202 and finally fastens with the fastening surface 203. The guide surface 202 is inclined with respect to the snap-fitting direction.

Although in the illustrated embodiment the cross-section of the clip portion 200 is trapezoidal, in other embodiments not shown, the cross-section of the clip portion 200 may be triangular or any other shape. Taking the example of a triangle, in this case, the proximal end 202a of the guide surface 202 is directly connected to the base body 100.

The base 100 may serve as a carrier for the clip portion 200. Taking the example of the clip 20 being disposed on the cover, in some embodiments, the base 100 may be a separate component, and the base 100 may be connected to the cover by welding, bonding, or screwing. In other embodiments, the base 100 may be part of a cover, and the base 100 and the cover may be formed as a single piece by injection molding or the like. Each clamping portion 200 may be disposed perpendicular to the surface of the substrate 100, or may be disposed at an angle with the surface of the substrate 100, which is not limited specifically.

The guide reinforcement part 300 may be connected between the guide surfaces 202 of at least two of the plurality of catching parts 200. In the illustrated embodiment, the guide reinforcement part 300 connects the guide surfaces 202 of all the snap parts 200. In other embodiments not shown, the guide reinforcement part 300 may be connected to a portion of the guide surface 202 of the snap-in part 200. When the guide reinforcement part 300 is coupled to the guide surface 202 of a portion of the catching parts 200, the guide reinforcement part 300 may be spaced apart and dispersedly disposed between the catching parts 200. For example, the guide reinforcement part 300 is provided between the first and second clip parts 200, and the guide reinforcement part 300 is provided between the third and fourth clip parts 200, while the guide reinforcement part 300 is not provided between the second clip part 200 and the third clip part 200.

In the embodiment of the present invention, in the buckle 20, part or all of the guiding surfaces 202 are connected to the guiding reinforcement 300, so that the guiding surfaces 202 can be connected into a whole through the guiding reinforcement 300, when a plurality of the connected guiding surfaces 202 receive a large external force which may cause deformation or damage of the guiding surfaces, the guiding reinforcement 300 can rapidly transmit the external force to other connected guiding surfaces 202 and the clamping portions 200 corresponding to the guiding surfaces 202, thereby reducing the probability that a single clamping portion 200 deforms or breaks relative to the base body 100. Therefore, the mechanical strength of the buckle 20 can be improved, and the strength requirement of the buckle 20 during disassembly and assembly can be met. In addition, because the guide reinforcing part 300 connects the clamping part 200 together at the guide surface 202, the guide reinforcing part 300 can also play a role in guiding to a certain extent, so that external force in the clamping process can be prevented from acting on the guide surface 202 completely, and damage to the connected clamping part 200 is avoided.

For example, the guide reinforcement member 300 may be coupled to the fastening surface 203. In the illustrated embodiment, the guide reinforcement portion 300 may extend downward and be connected to the fastening surface 203. It is the guide reinforcement 300 that is actually attached to the distal end 202b of the guide surface 202. The distal end 202b of the guide surface 202 is furthest from the base 100, i.e. the closer the snap adapter 40 slides along the guide surface 202 to the distal end 202b, the more force is applied to the guide surface 202 and the higher the mechanical strength requirements there. The guiding reinforcement part 300 extending to the fastening surface 203 can enhance the mechanical strength of the position with large stress, and the guiding reinforcement part 300 can also connect the fastening surface 203, so that the guiding reinforcement part 300 can share the acting force applied by the fastening adapter 40 after being fastened with the fastening adapter 40, thereby avoiding the damage of the fastening 20.

For example, the guide reinforcement 300 may extend from one end to the other end of the guide surface 202 along the oblique extending direction of the guide surface 202. Specifically, as shown in fig. 2-3, the guide reinforcement 300 may extend from the proximal end 202a of the guide surface 202 to the distal end 202b thereof. In this case, the guide reinforcement 300 is completely continuous and continuous along the oblique extending direction of the guide surface 202. Thereby, the mechanical strength of the clamping portion 200 can be further enhanced. In the buckling process of the buckle 20, the guide reinforcing part 300 can distribute the acting force acting on the clamping part 200 in the whole buckling process, so that the condition that the guide reinforcing part 300 is damaged can be further avoided, and the fracture of the joint of the clamping part 200 and the base body 100 can also be avoided.

Illustratively, the guide reinforcement part 300 may connect the guide surfaces 202 of all the snap-in parts 200. The guide reinforcement 300 is continuous with all the guide surfaces 202 in a predetermined direction. In some embodiments, the guide reinforcement 300 extends from one end to the other end of the guide surface 202 along the oblique extension direction of the guide surface 202. In other embodiments, the guide reinforcement 300 may be connected to only a portion of the guide surface 202 along the oblique extension of the guide surface 202, for example, to a portion of the guide surface 202 near its distal end 202b, or to a portion of the guide surface 202 near its proximal end 202a, or to a middle portion of the guide surface 202, or a combination thereof. When the guide reinforcement part 300 is connected to the guide surfaces 202 of all the clip parts 200, the mechanical strength of the clip 20 can be further improved, and the clip parts 200 which are not connected can be prevented from being damaged.

Illustratively, the guide reinforcement 300 may extend along the guide surface 202. As a whole, the surface of the guide reinforcement 300 and the surface of the guide surface 202 are smoothly connected. In this case, the guide reinforcement 300 may also have a guiding function. The outer surface of the guide stiffener 300 facing away from the base 100 may be coplanar with the guide surface 202. Thus, the guide reinforcement 300 may guide the snap adapter 40 together with the guide surface 202.

Illustratively, the guide reinforcement 300 has an inner surface facing the base 100, and the inner surface may surround the cavity 50 with the adjacent clip portion 200 and the base 100. The end of the guide surface 202 closer to the base 100 (i.e., the proximal end 202 a) is spaced from the base 100 to form the opening of the cavity 50. The opening of the cavity 50 may face in the same direction as the proximal end 202a of the guide surface 202. The cross section of the cavity 50 perpendicular to the predetermined direction X-X may be rectangular or may be trapezoidal with a large opening and a small interior. In some embodiments, the clip 20 is a plastic component, and the cavity 50 has a rectangular cross section perpendicular to the predetermined direction or a trapezoidal cross section with a large opening and a small interior, which is beneficial for a mold-drawing operation in an injection molding process. Further, the cavity 50 spaces the base body 100 and the guide reinforcement 300, and it is possible to prevent the thickness of the base body 100 from being affected, thereby preventing the appearance of the base body 100 from being deformed after injection molding.

Illustratively, as shown in fig. 5, the clip 20 further includes a clip reinforcement portion 204, and the clip reinforcement portion 204 may be connected between the fastening surfaces 203 of at least two of the plurality of clip portions 200. In the illustrated embodiment, the clip reinforcing portion 204 is connected to the fastening surfaces 203 of all the clip portions 200. In other embodiments, not shown, the fastening reinforcement portion 204 can be connected to a portion of the fastening surface 203 of the fastening portion 200. When the clip reinforcing portion 204 is connected to a portion of the fastening surface 203 of the clip portion 200, the clip reinforcing portion 204 may be spaced apart and disposed between the clip portions 200. For example, the clamping reinforcement portion 204 is provided between the first and second clamping portions 200, the clamping reinforcement portion 204 is provided between the third and fourth clamping portions 200, and the clamping reinforcement portion 204 is not provided between the second clamping portion 200 and the third clamping portion 200. The clamping reinforcement 204 may be rectangular, trapezoidal, or other shaped flat or curved surface. The mechanical strength of the clip 20 can be further enhanced by providing the clip reinforcement portion 204.

Illustratively, the clamping reinforcement 204 may also connect the base 100 and the end of the guide surface 202 that is farther from the base 100 (i.e., the distal end 202 b). The base 100, the distal end 202b of the guide surface 202 and the fastening surface 203 are connected together by the fastening reinforcement portion 204, so that the mechanical strength of the fastener 20 can be further improved, and the fastener can be prevented from being broken. Of course, in other embodiments not shown, the fastening reinforcement portion 204 may be connected to the fastening surface 203 near the base 100, or may be connected to the fastening surface 203 near the guide reinforcement portion 300, or may be connected to the middle of the fastening surface 203, or a combination thereof.

Illustratively, the snap reinforcement 204 may surround the guide reinforcement 300, the adjacent snap portion 200 and the base body 100 to form a cavity 50, which may have an opening facing in the same direction as the proximal end 202a of the guide surface 202, and the side of the cavity opposite to the opening may be closed by the snap reinforcement 204. This can further improve the mechanical strength of the clip 20.

For example, as shown in fig. 3, a cross-section of the guide reinforcement 300 perpendicular to the predetermined direction may have a wedge shape. The closer the wedge shape is to the distal end 202b of the guide surface 202, the larger the dimension. The wedge shape has a maximum dimension at the distal end 202b of the guide surface 202. The guide reinforcement 300 having a wedge-shaped cross section perpendicular to the predetermined direction has better support and strength by itself. In some embodiments, the clamping reinforcement part 204, the inner surface of the guide reinforcement part 300, the adjacent clamping part 200 and the base body 100 can form a cavity, and the size of the wedge shape closer to the distal end 202b of the guide surface 202 is larger, so that a cavity with a large opening and a small bottom can be formed, and the cavity is provided for facilitating the mold drawing operation in the injection molding process.

According to a second aspect of the present invention, as shown in fig. 4 to 5, there is provided a cap body including a face cover 10 and an inner cap 30, the face cover 10 covering an outer surface of the inner cap 30, one of the face cover 10 and the inner cap 30 may be provided with any one of the above-mentioned buckles 20, and the other of the face cover 10 and the inner cap 30 may be provided with a buckle adapter 40 adapted to the buckle 20. The surface cover 10 and the inner cover 30 are buckled through any one of the buckles 20, the buckle 20 has good strength, and if the buckle 20 needs to be repeatedly disassembled and assembled in the production or use process of the cover body, the buckle 20 is not easy to damage, and the rejection rate can be reduced.
