Description

core opener

technical field

The invention relates to household daily utensils, in particular to an utensil for breaking shells of nuts.

Background technique

Nuts such as walnuts, hickory nuts, and pecans are nutritious and popular foods. However, their shells are hard and difficult to peel off with bare hands. Therefore, various types of core openers appear on the market for people to choose. The most common one is the metal pliers type, its two metal handles are pivotally connected, and grooves or tooth shapes are formed on the handle near the pivot position to accommodate and hold nuts. By squeezing the handles, the nuts Shell crushed. On the basis of metal pliers, improvements can also be made, such as making it have a streamlined shape and adding a plastic shell. However, due to the limitation of its working principle, the pliers-type nuclear opener will inevitably cause fragments to fly around when used.

In order to prevent the fragments from flying out, on the basis of the pliers-type core opener, a cone is formed on the handle near the pivot to accommodate the nuts, thereby preventing the fragments from flying out within a certain angle range.

Or, there is also a new structure of the core opener, a metal tube is divided into two sections through the oblique section, you only need to put the nuts into the opening of the oblique section, and then splicing the two sections of metal tube together, each of the two sections of metal tube contains Half the nuts. Due to the misalignment of the beveled surface as it rotates, the nuts are crushed with just one twist. However, if only half of the nut is crushed, the remaining half is likely to get stuck in the opening, and it will be more difficult to continue crushing the rest of the nut afterwards.

All in all, the existing nuclear opener mainly has the following disadvantages: a, no matter from the aesthetic point of view, or from the angle of feel, it cannot cater to the taste of modern people; b, the moment of opening the core will cause debris to fly around; c 1. The kernels are not complete after opening the core; d. The remaining nuts are easy to get stuck in the core opener; e. The quality is large and it is not easy to carry.

Contents of the invention

The present invention aims at the deficiencies of various existing kernel openers, and provides a new structure nuclear opener, which can evenly crush hard nut shells and shell them with ordinary hand strength, without causing Fragments fly around, and whole kernels can be extracted.

The technical solution adopted by the present invention is: a nuclear opener, comprising: an outer frame with a cavity and an opening, the outer frame includes a plurality of non-contact cantilevers protruding from its middle position; Inside the cavity of the outer frame, there is also an inner frame with a cavity and an opening, and a cover that can be separated from the opening of the inner frame is provided with a through hole on the inner frame; the nail that is slid through the through hole, The inner side of the nail is inserted into the inner frame, and the outer side is against the cantilever; the guide groove arranged on the periphery of the outer frame surrounds the hoop in the guide groove, and the end of the hoop has a handle for adjusting its length.

The nut opener of the present invention abandons the simple surface contact form in the past, and adopts scattered metal nails, multi-point contact, and simultaneous force from different angles to open nuts. More advantages and technical effects of the present invention will be described in detail below.

Detailed ways

The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation is provided, but the protection scope of the present invention is not limited to the following embodiments.

Referring to the core opener shown in Fig. 1, it comprises an outer frame 7 that is roughly in the shape of a hemispherical shell, and an inner frame 1 that is fixed in the cavity of the outer frame 7 and is generally in the shape of a hemispherical shell; the outer frame 7 is not a complete hemisphere shell, but includes a plurality of non-contact cantilevers 70 protruding outward from its middle position; the through hole 10 provided on the inner frame 1 slides the nail 2 that is set in the through hole 10, and the The inner side of the nail 2 is inserted into the inner frame 1, and the outer side abuts against the cantilever 70; the guide groove 4 arranged on the periphery of the outer frame 7 surrounds the hoop 6 in the guide groove 4, and the end of the hoop 6 has a function to adjust its Length of handle 5.

The main components are described below:

Referring to Fig. 2, the hoop 6 is a common hoop 6 in the existing market, the end of the hoop 6 has a chute, and the handle 5 has a gear meshing with the chute (similar to the principle of a worm gear). Only the handle 5 is lengthened, which increases the length of the rotating arm.

Referring to FIG. 3 , the outer frame 7 is preferably elastic metal, and has four non-contact cantilever arms 70 protruding outward from its middle position, forming a roughly hemispherical shell-shaped cavity with an opening. Returning to FIG. 1 , each cantilever 70 abuts against the outer side of a nail 2 correspondingly. The nails 2 are made of metal, and there are four nails evenly distributed along the circumferential direction. The outer end of the nail 2 has an enlarged outer end surface 20, and the outer side of the nail 2 is covered with a spring 3 in a compressed state, one end of the spring 3 abuts against the outer end surface 20, and the other end abuts against the outer surface of the inner frame 1. surface. Due to the setting of the compression spring 3, each nail 2 maintains a relatively expanded state, which is convenient for nuts to be put into the inner frame 1.

Referring to FIG. 4 , the inner frame 1 can be made of plastic to form a roughly hemispherical shell-shaped cavity with an opening, which has the advantage of light weight. The bottom of the inner frame has a threaded hole (lower position in the middle of Fig. 4), which is fixedly connected with the outer frame 7 by screws.

Referring to Fig. 5, when the core opener is in use, after putting the nuts into the cavity of the inner frame 1, a cover 8 is needed, which is threadedly connected with the opening of the inner frame 7, and the main function of the cover 8 is to hold down the nuts , to make it positioned and prevent sliding. Turn the handle 5 to shorten the length of the hoop 6, and then compress the cantilever 70 to make them gather together, and drive the nails 2 to advance along the radial direction of the inner frame 1. At this time, the four nails 2 simultaneously press the nut shell to make it break . After the core opening is completed, the handle 5 is rotated in the opposite direction, and the cantilever 70 expands. Under the action of the spring 3, the nail 2 moves away from the radial direction of the inner frame 1 and returns to the initial position.

From the above description, it can be seen that the kernel opener has the following features and advantages: a. The rotational movement of the handle is used instead of direct pressure, which saves labor; When the machine is used, the fragments fly around; c, the movable metal nail overcomes the limitation of the size and shape of the nut itself, so the core opener can be widely applied to walnuts, small walnuts and hickory nuts of different sizes; d, use The rotation movement replaces the direct compression movement, which will not produce a large instantaneous displacement, and the symmetrical extrusion of multiple metal nails ensures the relative integrity of the nuts; e, the structure is simple, the material is light, the quality is small, and it is easy to carry; f. The increased handle further reduces the operating force.

Although the present invention is disclosed as above with preferred embodiments, it is not used to limit the claims. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of protection should be based on the scope defined by the claims of the present invention.
