Detailed Description

The present application will be further described with reference to the following specific embodiments, and it should be noted that, on the premise of no conflict, new embodiments may be formed by any combination of the embodiments or technical features described below.

In the description of the present application, it should be noted that, for the azimuth words such as terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the azimuth and positional relationships are based on the azimuth or positional relationships shown in the drawings, it is merely for convenience of describing the present application and simplifying the description, and it is not to be construed as limiting the specific scope of protection of the present application that the device or element referred to must have a specific azimuth configuration and operation.

It should be noted that the terms "first," "second," and the like in the description and in the claims are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

The terms "comprises" and "comprising," along with any variations thereof, in the description and claims, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The inventor of the present application has found that in the prior art, the insert of the clip body adopts a connection mode that the insert is inserted into the socket from inside to outside. Therefore, if the length is too long, even if the two ends of the cutting are combined by force, the combined length is larger than the distance between the inserting seats, and the handle body is difficult to be installed in the clamp body. The prior art slips are generally shorter, but this results in a smaller contact area between the slip and the socket, and thus in less strength and less load carrying capacity. After long-term use, the cutting is easy to bend or break, the socket is easy to bend or break, and the service life is short.

Improvements are made to this, as shown in fig. 1-5, the preferred embodiment of the present application is:

The utility model provides a high strength binder clip, includes the clamp body 1 and the handle body 2, and the bottom edge of clamp body 1 is equipped with socket 111, and the bottom of handle body 2 is equipped with the inside extension and forms cutting 21, and cutting 21 is suitable for along the inside connection of inserting socket 111 of axial to realize clamp body 1 and handle body 2, and the length of cutting 21 is greater than the length of socket 111.

In other embodiments, the length of the slip 21 may be equal to the length of the socket 111.

According to the application, the matching mode of the cutting 21 and the inserting seat 111 is changed, and the cutting 21 formed by outward extension in the prior art is improved to be extended inwards, so that the length of the cutting 21 can be set to be greater than or equal to the length of the inserting seat 111 without considering space problems when the length of the cutting 21 is set, and compared with the prior art, the length of the cutting 21 is longer, so that the stress area is larger, and the cutting has the advantages of strong load capacity, high strength and long service life.

Further, in the present embodiment, the end of the cutting 21 is provided with a clamping connector 211, and the clamping connector 211 is adapted to axially penetrate out of the socket 111 and then clamp with the socket 111. The above structure further increases the stability of the fit between the cutting 21 and the socket 111, thereby further improving the strength of the binder clip.

Specifically, as shown in fig. 2 and 3, in the present embodiment, the clamping connector 211 has a conical structure, and the radius of the bottom surface is larger than the inner diameter of the socket 111. The conical structure can facilitate the insertion of the clamping connector 211, so that the user can force the clamping connector to elastically deform, and the process of penetrating through the plug seat 111 is more convenient and smoother. The radius of the bottom surface is larger than the inner diameter of the socket 111, so that after the socket 111 is penetrated, the socket can bring stable limiting effect, thereby ensuring the stability of the matching.

Further, as shown in fig. 1 and 2, in the present embodiment, a retracting portion 23 which is bent and extends inward is provided between the main body 22 portion of the shank 2 and the cutting 21. The function of the retraction portion 23 is: 1. the structure of the portion connected to the cutting 21 is made more complex, so that the stability of the portion is made better, thereby increasing the strength of the product. 2. The volume of the product is effectively reduced, so that the product is more compact.

Specifically, in the present embodiment, the retraction portion 23 has an L-shaped cross section. The structure is simple, and the stability is strong.

As shown in fig. 2 and 4, in the present embodiment, the clip body 1 includes two side plates 11 and a bottom plate 12, the side plates 11 are connected by the bottom plate 12, the socket 111 is disposed at the bottom of the side plates 11, and an inner recess 121 is disposed in the middle section of the bottom plate 12. When the binder clip is opened, the middle section of the bottom plate 12 is a stress concentration position, so that the concave part 121 is arranged at the position, so that the stress distribution is more uniform, the bending fatigue resistance at the position is increased, and the service life of a product is prolonged.

Further, as shown in fig. 5, in the present embodiment, the cross section of the concave portion 121 has a fan-shaped annular structure with a thick middle and gradually thinner sides. The gradually thinned structure can effectively improve the uniform distribution of stress, and avoid the increase of the probability of fracture at a certain position caused by overlarge concentration of stress at the certain position, so that the strength and the service life of the product can be further improved.

In this embodiment, the handle body 2 is made of a material having a high elastic modulus. Therefore, as shown in fig. 3, the installation mode of the product is as follows: the two sides of the handle body 2 are broken off by force, then the cutting 21 is aligned with the inserting seat 111, and then the cutting is slowly released, because the handle body 2 is made of a material with high elastic modulus, the cutting can automatically shrink under the action of high resilience force, gradually insert into the inserting seat 111, and then the cutting head 211 can smoothly and conveniently penetrate out of the inserting seat 111 by being matched with manual force application, so that the installation is completed.

It should be noted that, in the present embodiment, the socket 111 is formed by folding the bottom edge of the clip body 1 outwards. The structure is simple to manufacture and low in cost.
