Abstract
The utility model relates to a disposable press button, belonging to the technical field of press button. A male button inserting piece of the utility model is a cylinder projection with a taper, wherein, the male button inserting piece has a smooth surface and an axial section which is an arrow head shape or a fungus shape; a female button inserting piece of the utility model is two slender rods which are paralleled positioned in the female button; and the space between the slender rods is slightly smaller than the maximum diameter of the projection of the male button. The design proposal of the utility model can easily and effectively achieve the disposable aim of press button; moreover, the utility model has the advantages of simple fabrication, low cost and suitable polarization.
Description
One technical field
The utility model relates to snap-fastener commonly used in daily life, particularly a kind of disposable snap-fastener.
Two background technologies
Snap-fastener is widely used on the article such as clothing, documents pouch, plays to connect and fixing effect, has brought very big convenience for people's life.Present snap-fastener mostly is repeatable design greatly, and in real life, needs the dead snap-fastener of the disposable button of a kind of energy sometimes, as is used in sealing of documents pouch, to prevent that internal file from arbitrarily being taken out.Relevant at present this disposable snap-fastener design seldom, Chinese patent " disposable snap-fastener " (patent No. 96219708.4) has provided a kind of relevant design, but the main purpose of this design is not the disposable use of snap-fastener, comparatively trouble is installed, complex structure, manufacturing cost is higher, and mainly is applicable to clothing.
Three summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art, provides a kind of novel disposable snap-fastener design, can realize target simple and effectively.
The transformation that the technical solution of the utility model is based on common snap arrangement proposes, concrete scheme is as follows: disposable snap-fastener, sun button, cloudy button are still formed by chimeric of positive and negative and separately riveting parts riveted respectively, chimeric of the sun button is the cylindric projecting block of variable cross-section, and chimeric of cloudy button is two thin bars.
The cylindric projecting block of described variable cross-section, smooth surface, its axial cross section shape approximation is arrow-shaped or mushroom-shaped, and near the medium position of projecting block, it is maximum that the diameter of radial section reaches, from here to the top-direction of projecting block, the diameter of radial section steadily reduces, and the side line of projecting block is slip circle shape, and to the bottom direction of projecting block, the diameter of radial section has individual bust, remains unchanged afterwards or steadily reduces.
Described two thin bars are arranged in parallel in the moon button inside, and spacing is slightly less than the maximum gauge of sun button projecting block.
Working mechanism of the present utility model is: when with external force sun button and cloudy button being combined, it is inner that chimeric (the cylindric projecting block of variable cross-section) of sun button stretches into cloudy button, contact two thin bars, because sun button projecting block smooth surface, and anterior side line is slip circle shape, so cross two thin bars that spacing in the cloudy button is slightly less than self maximum gauge by being not difficult after the external force.In case after crossing, then two thin bars have blocked positive button projecting block, have realized the basic function of snap-fastener.When apply external force want to make sun button and cloudy deduction of points from the time, because the position of two thin bars is at the rear portion of sun button projecting block at this moment, be subjected to stopping of projecting block diameter of section largest portion, the stretching action of external force can only make it more closely be attached to projecting block diameter the best part, and can not cross, so can not reach the purpose of drawing back snap-fastener.Unless thin bar or chimeric damage of sun button may separate just sun is detained with cloudy button, and this moment, snap-fastener were also lost the function that reuses.So the design can reach the disposable purpose of snap-fastener.
The utility model can be made of various metals, synthetic resin or plastics.
The utility model is applicable to the occasion that all snap-fasteners are used, and has characteristics such as respond well, simple in structure, easy to operate, with low cost.

Five specific embodiment
Processing sun button comprises chimeric 1 and riveting parts 2.Chimeric 1 is the cylindric projecting block 1 of variable cross-section, smooth surface, its axial cross section shape approximation is arrow-shaped or mushroom-shaped, near the medium position of projecting block 1, and the diameter maximum of radial section, thus to the top-direction of projecting block 1, the diameter of radial section steadily reduces, and the side line of projecting block 1 is slip circle shape, and to the bottom direction of projecting block 1, the diameter of radial section has individual bust, remains unchanged afterwards or steadily reduces.Two kinds of possible examples are shown in accompanying drawing 1,2.
The cloudy button of processing comprises chimeric 3 and riveting parts 4 then.Chimeric 3 is two thin bars, is arranged in parallel in the moon button inside, and spacing is slightly less than the maximum gauge of sun button projecting block 1.As shown in Figure 3.
Claims (4)
1. disposable snap-fastener, positive and negative deduction of points are not formed by chimeric of positive and negative and separately riveting parts riveted, and it is characterized in that: chimeric of the sun button be the cylindric projecting block of variable cross-section, and chimeric of detaining of the moon is two thin bars.
2. disposable snap-fastener according to claim 1, it is characterized in that: the smooth surface of the cylindric projecting block of variable cross-section (1), near medium position, the diameter maximum of its radial section, to top-direction, the diameter of radial section steadily reduces by this place, the side line of projecting block is slip circle shape, and to bottom direction, the diameter of radial section has individual bust, remains unchanged afterwards or steadily reduces.
3. disposable snap-fastener according to claim 1 is characterized in that: two thin bars are arranged in parallel in the moon button inside, and spacing is slightly less than the maximum gauge of sun button projecting block.
4. disposable snap-fastener according to claim 1 is characterized in that: can make of various metals, synthetic resin or plastics.
