Abstract
Description
Technical Field
[0001] The utility model specifically relates to a fruit knife with safe use. Background Art
[0002] The fruit knife with a built-in locking sheath is safe, practical and beautiful! When in use, press the locking switch and gently pull out the sheath to separate it from the blade. After use, insert the blade into the sheath. When you hear a "click" sound from the locking switch, it means that the sheath is completely locked. The sheath and the blade are integrated, which is safe, practical and convenient to carry. However, for the existing structure of the locking sheath, the locking positions of the lock catches are relatively delicate, and the sheath and the lock catches rub against each other frequently, resulting in wear. It is easy to have the situation of loose locking after long-term use. In addition, the lock catches of the existing structure of the locking sheath are asymmetrically installed on one side of the blade, and the locking force is applied to the blade unidirectionally, which will cause the insertion structure of the blade to be unbalanced and prone to deformation and wear of the blade. Content of the Utility Model
[0003] The utility model provides a fruit knife with safe use to solve the above-mentioned technical problems, and specifically adopts the following technical solutions:
[0004] A fruit knife with safe use, comprising: a sheath, a blade and a handle; the blade is fixed to one end of the handle; the sheath is sleeved on the outer periphery of the blade; the handle is formed with an installation cavity; a locking rod for locking the insertion position of the sheath is rotatably installed in the installation cavity; a spring piece for abutting against one end of the locking rod to keep the locking rod in the locking position is further arranged in the installation cavity; the other end of the locking rod is formed with a lock catch; an insertion convex part is formed at the end of the sheath for inserting the blade; a plurality of slots for inserting the corresponding insertion convex parts are formed on the end face of the handle; a lock groove for cooperating with the lock catch is formed on the insertion convex part.

Detailed implementation manners
[0020] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, but should not be construed as limiting the present application.
[0021] In the description of the present application, unless otherwise clearly specified and defined, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0022] In the present application, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above and over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.
[0023] As Figures 1 to 2 shown, a fruit knife 10 with safe use according to the present application includes: a knife sheath 11, a knife body 12, and a knife handle 13. The knife body 12 is fixed to one end of the knife handle 13, and the knife sheath 11 is sleeved on the outer periphery of the knife body 12 to protect the knife body 12.
[0024] Specifically, the knife handle 13 is formed with an installation cavity 131. A locking rod 14 is rotatably installed in the installation cavity 131, and the insertion position of the knife sheath 11 can be locked through the locking rod 14. A spring piece 15 is further provided in the installation cavity 131, and the spring piece 15 is used to abut against one end of the locking rod 14 to keep the locking rod 14 in the locking position. The other end of the above-mentioned locking rod 14 is formed with a lock catch 141. The end of the knife sheath 11 for inserting the knife body 12 is formed with an insertion convex portion 111, and the end face of the knife handle 13 is formed with a plurality of slots 132 for the corresponding insertion of the insertion convex portion 111. The insertion convex portion 111 is formed with a lock groove 1112 for cooperating with the lock catch 141.
[0025] Specifically, after the fruit knife is used, the blade body 12 is inserted into the scabbard 11. When the blade body 12 is inserted into place, the insertion protrusion 111 of the scabbard 11 is just inserted into the slot 132. When the insertion protrusion 111 is inserted into the slot 132, the other end of the locking rod 14 is pushed to rotate and tilt up. When the insertion protrusion 111 is inserted into place, the lock buckle 141 at the other end of the locking rod 14 just falls into the lock groove 1112, thereby locking the position of the scabbard 11, preventing the scabbard 11 from falling off and causing safety hazards, and making it safer to use.
[0026] As a specific implementation, an installation groove is formed in the installation cavity 131, one end of the spring sheet 15 is inserted into the installation groove, and the other end abuts against the lower side of one end of the locking rod 14. This structure is simple and can improve the stability of the installation position of the spring sheet 15.
[0027] Furthermore, a driving inclined surface 1111 is formed on the end surface of the insertion protrusion 111. When the insertion protrusion 111 is inserted into the slot 132, the driving inclined surface 1111 can guide and drive the other end of the locking rod 14 to tilt up, and the insertion structure is smoother.
[0028] As a specific implementation, one end of the locking rod 14 is formed with an insertion hole 142 for inserting the spring piece 15, and one end of the spring piece 15 is inserted into the slot 132, and one end of the spring piece 15 is inserted into the insertion hole 142. In this way, the stability of the installation structure of the spring piece 15 can be improved, and the elasticity of the spring piece 15 can be fully utilized, so that the other end of the locking rod 14 can stably press the insertion protrusion 111, thereby improving the stability of the locking structure.
[0029] Furthermore, a limiting protrusion 133 is formed in the mounting cavity 131, and the rotation position of the locking rod 14 can be limited by the limiting protrusion 133, thereby preventing the scabbard 11 from being pressed too tightly due to excessive pressing force at the other end of the locking rod 14, thereby preventing the scabbard 11 from pressing the blade 12 and wearing the blade 12.
[0030] Furthermore, the left side wall and the right side wall in the scabbard 11 are both formed with a pressing surface 113 , and the pressing surface 113 can press the blade 12 when the blade 12 is inserted into the scabbard 11 to prevent the blade 12 from shaking in the scabbard 11 .
[0031] Therefore, the above-mentioned safe fruit knife 10 locks the blade 12 through the structural cooperation between the insertion protrusion 111 of the scabbard 11, the slot 132 of the handle 13 and the locking rod 14. The locking structure is located outside the scabbard 11 and does not affect the blade 12 inserted into the scabbard 11. Through the groove buckle clamping structure at the end of the scabbard 11, the lock is not likely to loosen after long-term use.
[0032] In addition, the locking structure of the safe-to-use fruit knife 10 of the present application is located outside the knife sheath 11, and it locks the relative positions of the knife sheath 11 and the knife handle 13 from one end of the knife sheath 11. The locking force has no impact on the blade 12 at all, so it will not affect the insertion balance of the blade 12 itself, and it is not easy to cause extrusion deformation or wear to the shape and outer circumference of the blade 12, thus not affecting the structural accuracy of the blade 12.
[0033] In the above solution, a limiting hole 112 is formed at one end of the knife sheath 11 away from the end for the tip of the blade 12 to insert, so as to limit the position of the blade 12 and further improve the stability of the insertion of the blade 12.
[0034] Furthermore, slots 132 are formed at the corresponding positions on the upper side and the lower side of the end face of the knife handle 13, and insertion protrusions 111 are formed at the corresponding positions on the upper side and the lower side of the end of the knife sheath 11. Locking grooves 1112 are formed on the insertion protrusions 111 on the upper side and the lower side of the end of the knife sheath 11. Limiting holes 112 are formed at the corresponding positions on the upper side and the lower side of one end of the knife sheath 11 away from the end for the tip of the blade 12 to insert. With such a structure, no matter whether the blade 12 is inserted into the knife sheath 11 with the back of the blade facing up or with the back of the blade facing down, the blade 12 can be inserted and the insertion position of the knife sheath 11 can be locked. The structure is simple and convenient to use.
[0035] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the above embodiments do not limit the present utility model in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.
