Description

Safety protection diving knife with double buckle

This creation is about a diving knife, especially a safety protection diving knife with a double buckle.

The conventional safety protection diving knife comprises a shank portion which is elongated and has an arc-shaped cross section, and has an elongated groove formed therein; a blade portion which is sharp and severable and cut An object of the object, wherein one end of the blade portion is placed in the shank portion. The sheath portion includes a front cover and a back cover combined. The front cover and the rear cover may be combined into a closed sheath portion having an opening below the shank portion. For the purpose of safety protection, a buckle structure is provided in front of the diving knife, and the shank portion below the blade portion is fastened to the sheath portion in a snap-fit manner. By pressing the press-fit structure, the shank can be disengaged from the scabbard and the blade can be removed.

However, this conventional structure has only a single crimping structure, and the press button is located on the front side of the sheath portion, so that when diving, there is a possibility that the buckle structure is touched by carelessness, causing the blade to be separated from the sheath. The loss of the lighter blade is not easy to find, and the heavy one hurts the diver, which leads to misfortune.

In view of the structural composition of the case, and the functions and advantages that can be produced, in conjunction with the drawings, a preferred embodiment of the present invention is described in detail below.

Referring to Figures 1 to 3, the safety protection submersible knife of the left and right double buckles of the present invention includes the following components: a shank portion 1 which is elongated and has a curved cross section, and the inside thereof is formed. An elongated groove 10, which is approximately hexagonal in shape, and the outer shape of the shank portion 1 includes two broad sides and two narrow sides, the shape of which forms a streamlined curve and has a slightly concave abdomen curve. It also happens to be a curve design that is easy to hold by hand.

a snap block 2, the snap block comprising a body 20 and two from the left and right sides of the body A flexible button 21 extending upwardly from the lower side.

The transverse section of the body 20 is approximately rectangular, and the central portion of the body forms a penetrating longitudinal perforation 201; the bottom of the body is widened to form a hexagonal base 202 corresponding to the top of the shank 1 a recessed groove 10; the base is placed in the recess to fix the position of the snap block 2; further, the elastic button 21 is integrally formed with the snap block 2, and each elastic button 21 extends upward from the bottom The upper part is divided into two, and a claw shape is formed, and each claw forms a buckle 210 on the near body side; and a pressing key 211 is formed away from the body, and the outer periphery of the pressing key forms a non-slip block 212 so that the finger pressing does not slide. .

A blade portion 3 is a sharply cuttable object that cuts an object, wherein one end of the blade portion 3 is inserted into the longitudinal through hole 201 of the latching portion 2.

A sheath portion 4 is composed of a front cover 40 and a rear cover 41. The front cover 40 is formed into a concave structure, and the rear cover 41 may be a planar structure or have a structure corresponding to the concave structure of the front cover. A plurality of fastening holes 410 are formed in the rear cover 41, and the front cover 40 forms a plurality of fastening protrusions. Applying a plurality of fastening holes 410 on the back cover to engage a plurality of fastening protrusions on the front cover, the two can be combined into a closed sheath portion, and an opening 411 is disposed below the shank portion. .

A fixing block group 43 is further disposed on the rear cover 41. The fixing block group 43 is composed of two upper and lower fixing blocks, and an accommodation space 400 is formed therebetween, and the four sides of the fixing block group 43 are locked to the rear. The outer ends of the plurality of fastening holes 410 are covered so that the fixing block group 43 is fixed to the rear cover 41. An elastic hook 430 protrudes from each of the left and right sides of the fixed block group.

When assembled, the shank portion is deep into the sheath portion, so that the elastic hook of the fixed block group fastens the elastic button of the buckle portion; thus the sheath portion is tightly engaged with the shank portion State; otherwise, if you want to remove the blade, just Pressing the pressing buttons on both sides of the snap block to the inner side, so that the pressing button forces the inner hook to separate from the elastic hook below the fixing block, the blade can be extracted and separated from the sheath portion.

The advantage of the present invention is that the two elastic buttons are disposed at both ends of the shank portion, and the two elastic claws must be pressed at the same time to pull out the blade, so that it is not easy to cause a malfunction and pull out the shank, so it is quite safe. effect.

In summary, the humanized design of this case is quite in line with actual needs. The specific improvement of the existing defects is obviously a breakthrough improvement advantage compared with the prior art, and it has an improvement in efficacy and is not easy to achieve.
