Detailed ways

In order to achieve the above-mentioned purpose and effect, the technical means and the structure adopted by the utility model are hereby illustrated in detail with respect to the preferred embodiments of the utility model. Its features and functions are as follows, so as to fully understand.

Please refer to Figures 1 to 3, it can be clearly seen from the figures that the components of the present invention are composed of an upper clip 1, a lower clip 2 and a push rod 3, so the main structure of this case is described in detail as follows:

One side of the upper clip 1 is provided with a flat piece 11, and the lower surface of the piece 11 is convexly provided with a serrated upper engaging portion 111, and the other end of the piece 11 is convexly provided with an arc-shaped The fastening part 12 is provided with an accommodating space 112 between the two fastening parts 12, and a corresponding abutting part 113 and an L-shaped protruding stop part are recessed on the opposite end surfaces of the two fastening parts 12 114 , and a corresponding shaft groove 121 is opened inside the accommodating space 112 , and an upward chamfer 1211 is set up below the shaft groove 121 .

The lower clip 2 has a flat piece body 21, and the piece body 21 protrudes a serrated lower engaging portion 211 at an appropriate position in front, wherein the end of the piece body 21 is provided with an abutting portion 212, and the piece body On both sides of the end of the body 21, a relative buckle 22 is extended at an appropriate position, wherein a corresponding shaft 221 protrudes from the outer side of the buckle 22 at an appropriate position, and a chamfer 2211 is provided above the shaft 221. Furthermore, A rectangular split groove 222 is provided at an appropriate position between the buckling parts 22, and an L-shaped elastic piece 223 is extended on one side of the split groove 222. In addition, a rectangular split groove 223 is provided at an appropriate position between the buckling parts 22 Baffle 224 .

The push rod 3 is provided with a pushing portion 31, and a hollow groove 311 is formed at the pushing portion 31, and a rod body 32 extends from the center of the bottom of the pushing portion 31, and a rectangular turning block is provided at the other end of the rod body 32. 33, the turn block 33 is protrudingly provided with two guide rail plates 331 at the end position.

When the utility model is assembled, the rotary block 33 of the push rod 3 is placed inside the accommodating space 112 of the upper clamp 1, and then the shaft 221 of the lower clamp 2 is moved along the corresponding guide angle 1211 with the guide angle 2211. Sliding card in the elongated shaft groove 121, at this time, the turning block 33 of the push rod 3 is positioned between the upper clip 1 and the lower clip 2, and then the three are combined into one, that is, the assembly of the utility model is completed action.

Please refer to Figures 4 to 7, the action when the utility model is about to be opened is to first pull the push rod 3 upwards, so that the upper corners of the two sides of the turning block 33 are rotated and pushed, and the side of the upper clip 1 is buckled. The upper wall surface of the accommodating space 112 of the part 12 and the inner wall surface of the abutment part 212 of the lower clip 2, when the rotating block 33 is pushed until the elastic piece 223 produces an elastic deformation, the lower clip 2 is centered on the shaft 221 Unscrew downwards, and the abutting portion 212 of the lower clip 2 leans against the abutting portion 113 of the upper clip 1, and the turning block 33 is positioned on the inner side of the stopper portion 114, which forms the open state of the present invention; After the ribbon 4 of the utility model penetrates into the gap between the sheet body 11 of the upper clip 1 and the sheet 21 of the lower clip 2, the push rod 3 can be pulled downwards, so that the turning block 33 pushes the shrapnel 223 first. After an elastic deformation occurs, the upper corner of one side of the rotating block 33 rotates and pushes and passes over the upper wall surface of the accommodation space 112 of the fastening part 12 on the side of the upper clip 1 and the inner wall surface of the abutment part 212 of the lower clip 2 , when the rotary block 33 pushes to the stopper 114 and the abutting portion 212, the lower clip 2 will abut upwardly to the upper clip 1 with the shaft 221 as the center, and the abutting portion 212 of the lower clip 2 will be Close the abutting portion 113 of the upper clip 1, when it stops, the upper engaging portion 111 of the upper clip 1 and the lower engaging portion 211 of the lower clip 2 are in a staggered shape, so that the webbing 4 is firmly clamped on the upper clip Between the sheet 1 and the lower clamping sheet 2, the closed use state of the utility model is formed.

Furthermore, when the rectangular turning block 33 of the push rod 3 of the present utility model rotates, its central point has an appropriate offset, so the turning block 33 utilizes the drop of the rotation angle to make it directly squeeze the stopper 114 and the leaning However, when this kind of hard force interferes and pushes, it is very easy to generate excessive friction force, which leads to the lack of smoothness of force. The establishment of the split groove 222 is to make the turning block 33 have moderate elastic deformation when rotating, so as to solve the problem of jamming or unsmooth rotation; in addition, the shrapnel 223 with the split groove 222 in the inner phase of the abutment part 212 can be used When the rotary block 33 is rotated to slightly in front of the end of the unscrewing stroke, it can have a buffering effect, so that the rotation will not be too stiff, and it can be pushed against the lower clip 2 to make the sheet 11 and the sheet 21 open. use.

In addition, the above-mentioned stopper 114 is set up in a stepped shape, and the corner is an acute angle. This design allows the turn block 33 to only slightly interfere with the middle stroke during the rotation process. When the operator pushes the push rod 3 o'clock even if do not once rotate to positioning, also can make the turn block 33 of push rod 3 suspend at stopper 114 places, and be the inclined state of an about forty-five degree.

In addition, although the upper meshing portion 111 of the upper clip 1 of the present invention and the lower meshing portion 211 of the lower clip 2 are described as being in a zigzag shape in this specification, the meshing design of the upper and lower clips can also be a pyramid, Cones, barbs, etc. have the structure of the engagement function. In addition, the rotating block 33 can also be designed in a polygonal shape, and the webbing 4 is also for providing a preferred embodiment for understanding. It can be recognized that this embodiment can be changed in many ways, but this simple change does not deviate from the broad concept of the utility model, so it can be understood that the utility model is not limited to the disclosed specific embodiment, but covers the scope of application for patents. The scope and spirit defined by the scope.

To sum up, the above-mentioned clamping buckle of the utility model can really achieve its function and purpose, so the utility model is actually a new creation with excellent practicability, and it truly meets the requirements for a utility model patent application, so the application is filed according to law.
