Description

A kind of anti-loosening kitchen knife

technical field

The utility model relates to a kitchen knife, in particular to a kitchen knife which can prevent loosening.

Background technique

The handle of an existing kitchen knife is generally riveted together by two wooden or plastic handles, which has the following disadvantages:

(1) After the handle of the knife is wet, the frictional force will be reduced. When the user chops food hard, the knife will be easily loosened from the hand, causing danger. (2) The knife handle expands with heat and contracts with cold, and there will be a little deformation, resulting in weak riveting, easy to fall off, and not durable.

Utility model content

In view of the above-mentioned defects in the prior art, the technical problem to be solved by the utility model is to provide a kitchen knife that can prevent loosening, which can reduce loosening and make it safer to use.

In order to achieve the above purpose, the utility model provides a kitchen knife that can prevent loosening, including a knife body (1), a knife handle (2) and a pair of knife handle pieces (3), the knife handle (2) and the knife body (1) Fixed connection, the pair of knife handles (3) clamps the handle (2) in the middle and is fixedly connected by rivets (4), characterized in that: the inner surface of the pair of knife handles (3) A pair of grooves (3a) for inserting the knife handle (2) are provided in the middle part respectively, and the upper and lower parts of the inner surface of the pair of knife handle pieces (3) are connected through dovetail groove structure. Using the above scheme, since the pair of knife handles (3) is provided with a pair of grooves (3a) on the opposite inner side, and the knife handle (2) is inserted into the pair of grooves (3a), so the knife handle (2) ) in the pair of knife handles (3) is restricted in the up and down direction and cannot move up and down; at this time, the knife handle (2) can only move along the groove length direction in the groove (3a); but because the knife handle (2) and The knife handle (3) is also clamped and restrained by the rivets (4), so the knife handle (2) cannot move along the long direction of the groove, so the knife handle (2) can only be stuck in the pair of groove (3a), thus ensuring that it will not loosen. Furthermore, in order to prevent the pair of handles (3) from loosening, the upper and lower parts of the inner surface of the handle (3) are connected through a dovetail structure, thus ensuring that the handle (3) is always They are fastened to each other and will not be disengaged from each other, which can ensure that the entire knife handle (2) and the knife handle piece (3) are always firmly locked.

Further, the cross section of the rivet (4) is polygonal. The rivet (4) can be prevented from rotating, and loosening caused by the rotation of the rivet (4) can be avoided.

Further, the knife handle (2) is integrally formed with the knife body (1). The knife handle (2) and the knife body (1) are made of the same steel material, and are formed by integral casting, which is strong enough, firm and reliable, and can also reduce the force deformation of the knife handle (2); It can ensure the overall strength of the structure, facilitate processing and assembly, reduce the number of parts, and reduce production and management costs.

Further, a hanging hole (11) is opened on the cutter body (1). Conveniently hangs on kitchen hooks after use.

Further, the hanging hole (11) includes a first hanging hole (111) and a second hanging hole (112), the first hanging hole (111) is a circular through hole, and the second hanging hole (112 ) is a polygonal via. It can be hung on the hook through the first hanging hole (111) and the second hanging hole (112), and the second hanging hole (112) is hung on the polygonal support hanging rod, which can avoid the kitchen knife from shaking. It is safer to put it.

Preferably, the handle cover (3) is made of wood or plastic material. The use of plastic can improve the comfort of holding; and the use of wood has anti-slip effect.

The beneficial effects of the utility model are: the utility model has a simple structure, and the knife handle and the blade handle are not easy to fall off, durable and safe to use.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Referring to Fig. 1 to Fig. 2, a kind of anti-loosening kitchen knife includes a knife body 1, a knife handle 2 and a pair of knife handle pieces 3, the knife handle 2 is fixedly connected to the knife body 1, and the pair of knife handle pieces 3 Said knife handle 2 is clamped in the middle thereof and then fixedly connected by rivets 4. It is characterized in that: a pair of grooves 3a for inserting said knife handle 2 are respectively opened in the middle of the pair of knife handle pieces 3 inner surfaces. The upper and lower parts of the inner surface of the knife handle 3 are connected through a dovetail groove structure. Adopt above-mentioned scheme, because this pair of knife handle pieces 3 is provided with a pair of groove 3a on the relative inner side, and this handle of a knife 2 is inserted in the described pair of grooves 3a, so handle of a knife 2 is in this pair of knife handle pieces 3 up and down. The direction is limited by the card and cannot move up and down; at this time, the handle of a knife 2 can only move along the groove length direction in the groove 3a; It cannot move along the length direction of the groove, so the handle 2 can only be locked in the pair of grooves 3a, thus ensuring that it will not loosen. Furthermore, in order to prevent a pair of knife handle pieces 3 from loosening each other, the upper and lower parts of the inner surface of the knife set piece 3 are connected through a dovetail groove structure, thus ensuring that the knife set pieces 3 are always clamped to each other without can be separated from each other, and can ensure that the entire knife handle 2 and the knife handle piece 3 are always firmly locked.

Further, the cross section of the rivet 4 is polygonal. The rotation of the rivet 4 can be prevented, and the loosening caused by the rotation of the rivet 4 can be avoided.

Further, the knife handle 2 is integrally formed with the knife body 1 . The knife handle 2 and the knife body 1 are made of the same steel material, and are formed by integral casting, which has sufficient strength, firmness and reliability, and can also reduce the force deformation of the knife handle 2; and the use of integral molding can better ensure the structural member The overall strength is also convenient for processing and assembly, reducing the number of parts and reducing production and management costs.

Further, a hanging hole 11 is opened on the cutter body 1 . Conveniently hangs on kitchen hooks after use.

Further, the hanging hole 11 includes a first hanging hole 111 and a second hanging hole 112, the first hanging hole 111 is a circular through hole, and the second hanging hole 112 is a polygonal through hole. It can be hung on a hook through the first hanging hole 111 and the second hanging hole 112, and the second hanging hole 112 is hung on a polygonal support hanging rod, which can avoid the kitchen knife from shaking and make it safer to pick and place.

Preferably, the handle cover 3 is made of wood or plastic material. The use of plastic can improve the comfort of holding; and the use of wood has anti-slip effect.

The preferred specific embodiments of the present utility model have been described in detail above.
