Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a quincuncial sheet which is arranged in a seat tube of a shock absorber on a bicycle. Referring to fig. 1, the quincunx sheet 1 includes a connecting portion 11 in a circular cake shape and a plurality of fastening portions 12 integrally formed on the connecting portion 11, and the number of the fastening portions 12 is at least two. In this embodiment, the number of the clamping parts 12 is six, the six clamping parts 12 are integrally formed at the edge of the connecting part 11, and the six clamping parts 12 are uniformly distributed along the circumferential direction. Not only the integral aesthetic property of the plum blossom sheet 1 is increased, but also the plum blossom sheet 1 is evenly stressed in the seat tube, thereby prolonging the service life of the plum blossom sheet 1.

Six chucking parts 12 all lie in connecting portion 11 with one side, six chucking parts 12 all are the slope setting, and homogeneous shaping is provided with the portion of bending 13 on every chucking part 12, and adjacent two are bent and are formed arc recess 14 between portion 13 and the chucking part 12, and when the staff took plum blossom piece 1, arc recess 14 had the guard action to staff's hand.

The bending part 13 bends towards the position close to the center of the connecting part 11, and the included angle between the bending part 13 and the connecting part 11 is an obtuse angle. When the quincunx sheet 1 is installed in the seat tube, one side of the clamping part 12 far away from the connecting part 11 abuts against the inner side wall of the seat tube, and one end of the bending part 13 far away from the connecting part 11 abuts against the inner side wall of the seat tube. Because the 13 location that the portion of bending is close to connecting portion 11 center is buckled towards, has not only increased the area of contact between the border of six chucking portions 12 and the seat pipe inside wall, has also increased the area of contact between the border of six portions of bending 13 and the seat pipe inside wall simultaneously to increased the area of contact between plum blossom knot and the seat pipe inside wall, and then increased the plum blossom and detained the fastness of installing in bicycle seat pipe.

The side wall of the clamping part 12 departing from the center of the connecting part 11 is provided with a first arc-shaped surface 122, the side wall of the bending part 13 departing from the center of the connecting part 11 is provided with a second arc-shaped surface 132, and the first arc-shaped surface 122 is matched with the inner side wall of the seat tube, so that the contact area between the clamping part 12 and the inner side wall of the seat tube is maximized, and the friction force between the clamping part 12 and the seat tube is maximized; the second arc-shaped surface 132 is matched with the inner side wall of the seat tube, so that the contact area between the bending part 13 and the inner side wall of the seat tube is maximized, the friction force between the bending part 13 and the seat tube is maximized, and the firmness of the plum blossom buckle installed in the seat tube of the bicycle is further improved.

The clamping part 12 is provided with a first round angle 121, and the bending part 13 is provided with a second round angle 131. When the worker takes the quincunx sheet 1, the first round angle 121 and the second round angle 131 reduce the pressure of the quincunx sheet 1 on the hand of the worker, and have a protection effect on the hand of the worker.

The embodiment of this application still discloses a plum blossom of using plum blossom piece is buckled, refers to fig. 2 and 3, and the plum blossom is buckled including plum blossom piece 1, installation section of thick bamboo 2 and connecting piece 3, and the shape of installation section of thick bamboo 2 is cylindric, and the one end of installation section of thick bamboo 2 is the opening setting, and the other end of installation section of thick bamboo 2 is to seal the setting. The connecting piece 3 is used for fixing the quincunx sheet 1 at the closed end of the mounting cylinder 2, and the quincunx sheet 1 is positioned outside the mounting cylinder 2. When the worker installs the quincuncial buckle in the seat tube, the friction force between the edge of the quincuncial buckle 1 and the inner side wall of the seat tube has a fixing effect on the quincuncial buckle 1, and therefore the whole quincuncial buckle is fixed in the seat tube.

The connecting piece 3 comprises a nut 31 and a connecting column 32, wherein the nut 31 is integrally formed at one end of the connecting column 32; the closed end of the mounting tube 2 is provided with a first penetrating hole 21, the connecting part 11 is provided with a second penetrating hole 111, and the first penetrating hole 21 is communicated with the second penetrating hole 111. One end of the connecting column 32 far away from the nut 31 sequentially passes through the first through guiding hole 21 and the second through guiding hole 111; the clamping ring 33 is stamped and formed at one end, away from the connecting column 32, of the connecting column 32, the clamping ring 33 is turned towards the outer side of the connecting column 32, and the clamping ring 33 and the nut 31 are respectively abutted to two side walls of the connecting part 11. In the production process, the staff passes the first hole 21 that leads on the installation section of thick bamboo 2 in proper order with the one end that nut 31 was kept away from to spliced pole 32, the hole 111 is worn to the second on the plum blossom piece 1, place the plum blossom knot in the squeeze riveter at last, keep away from the one end of nut 31 through squeeze riveter pressfitting spliced pole 32, thereby form grip ring 33, because grip ring 33 and nut 31 respectively butt in two relative lateral walls of connecting portion 11, thereby have clamping action to connecting portion 11, and then increased the fastness that plum blossom piece 1 is fixed in on installation section of thick bamboo 2.

One end of the connecting column 32 close to the clamping ring 33 is provided with a threaded hole, and the threaded hole on the connecting column 32 is communicated with the threaded hole on the nut 31. One end of the threaded hole close to the clamping ring 33 is provided with a third round corner 321, the third round corner 321 not only has a protective effect on the hand of a worker, but also increases the convenience of the worker for installing the cushion on the quincuncial buckle.

The mounting barrel 2 is provided with a plurality of avoiding holes 22, and the number of the avoiding holes 22 is at least two. In this embodiment, the number of the avoiding holes 22 is four, and the four avoiding holes 22 are circumferentially and uniformly distributed along the mounting cylinder 2. Because the installation cylinder 2 is formed by stamping, four avoiding holes 22 are formed in the installation cylinder 2, so that the installation cylinder 2 cannot be deformed by self extrusion in the process of stamping the installation cylinder 2 by a press machine and a die, and the attractiveness of the installation cylinder 2 after being formed is improved.

The embodiment of the application also discloses a production process of the plum blossom button, which comprises the following steps:

the method comprises the following steps: stamping the quincunx sheet 1 by a press machine and a die, pressing six clamping parts 12 on a connecting part 11 into an inclined state, and pressing a bending part 13 on each clamping part 12 so as to enable an included angle between each bending part 13 and each clamping part 12 to be an obtuse angle;

step two: carrying out heat treatment on the plum blossom slices 1;

step three: carrying out electrophoresis treatment on the plum blossom slices 1;

step four: one end of the connecting column 32, which is far away from the nut 31, sequentially penetrates through the first penetrating hole 21 on the mounting cylinder 2 and the second penetrating hole 111 on the plum blossom piece 1, and the end of the connecting column 32, which is far away from the nut 31, is pressed by a riveting machine, so that a clamping ring 33 is formed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
