Description

Seesaw button

Technical field

The utility model is on a kind of seesaw button using Improvement type axial aperture structure.

Background technology

Seesaw button is the conventional part of house distribution, makes simply and technical costs is cheap, generally using injection Forming technique mating mold can be manufactured largely, and ejection formation is exactly to heat plastic material in the barrel of Jet forming machine to melt Change, under plunger or screw pressurizing, molten plastic is compressed and moved forward when in flow regime, and then by barrel before The nozzle at end is so that in the relatively low Guan Bi mould of speed implantation temperature quickly, after certain time cooling and shaping, opening mold is Obtain product.

After the completion of plastic injection, it is necessary to products formed is taken out out of mould, is taken out for convenience, the design of plastic mould can divide Into upper and lower or left and right paired kenel, such mould and mould separate or be combined place just occur together with slot, Plastics are allowed to fill mould because must be pressurizeed when plastic injection, no matter how closely sealed mould is, and plastics are more or less bound to This road slot is got into, after products formed takes out from mould, one of vestige will be left on this road gap, this road vestige claims For die parting line.Similarly, the mould for making seesaw button can there are die parting line when dividing mould in the place of axle construction, and divide mould Line easily produces burr because of the problems such as mould and die accuracy, injection condition, and burr can cause axle to produce interference when being arranged in axis hole, make Start into seesaw button has some setbacks, or even card key.

Therefore, it is the problem of current industry remains unsolved the axial aperture structure of seesaw button how to be improved under technology today.

Embodiment

Illustrate embodiment of the present utility model by particular specific embodiment below, people skilled in the art can be by Content disclosed in the present specification understands other advantages and effect of the present utility model easily.The utility model also can be by it He is implemented or applied different specific embodiments, and the various details in this specification can also be based on different viewpoints and application, Various modifications and change are carried out in the case where not departing from spirit of the present utility model.

It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only coordinating specification to be taken off The content shown, for the understanding and reading of people skilled in the art, it is not limited to the enforceable restriction of the utility model Condition, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, in not shadow Ring under the effect of the utility model can be generated and the purpose that can reach, all should fall in the technology disclosed in the utility model In the range of Rong get Neng is covered.Meanwhile in this specification it is cited such as " on ", " interior ", " outer ", the term of " bottom " and " one ", It is merely convenient to narration to understand, and is not used to limit the enforceable scope of the utility model, its relativeness is altered or modified, In the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model, conjunction is first chatted bright.

It and please close and show refering to the outward appearance of seesaw lid that Fig. 1, Fig. 2-1 and Fig. 3, Fig. 1 are seesaw buttons of the present utility model It is intended to, Fig. 2-1 is the schematic appearance of the pedestal of seesaw button of the present utility model, and Fig. 3 is seesaw button of the present utility model Schematic diagram.The utility model provides a kind of seesaw button, mainly includes seesaw lid 1 and pedestal 2, wherein, the side wall of seesaw lid 1 10 have axis hole 11, and the side wall 20 of pedestal 2 is provided with the protruding shaft 21 of corresponding axis hole 11, and with mutually corresponding in protruding shaft 21 Two sections 211, seesaw lid 1 can be arranged in protruding shaft 21 to fix on the base 2 by axis hole 11, be pressed for user.Compared with Good, two sections 211 are symmetrical.

Then please continue to refer to Fig. 2-2, Fig. 2-2 is that the partial enlargement of the axial aperture structure of seesaw button of the present utility model shows It is intended to.As illustrated, implement in one kind in kenel, because seesaw button of the present utility model can be via plastic injection fabrication techniques Form, can be formed with die parting line 212 in protruding shaft 21, and the design of the section 211 of protruding shaft 21 is intersected with die parting line 212, is changed Yan Zhi, section 211 is may also appear in burr caused by die parting line 212, section 211 can be plane or concave surface, purpose It is the radius that the axle center of protruding shaft 21 to be allowed can be less than the protruding shaft 21 with the minimum range of section 211, when seesaw lid 1 and pedestal During 2 combination, axis hole 11 can be fastened on protruding shaft 21 to fix seesaw lid 1 and pedestal 2, via the formation of section 211, section 211 and A sufficiently large gap is had between axis hole 11 allows burr to exist and be unlikely to touch the madial wall of axis hole 11, and then avoids hair Thorn interference protruding shaft 21 is in the start of axis hole 11.

In an embodiment of the present utility model, the aperture Φ A (Fig. 1) of axis hole 11 preferably between 2.1mm to 4.1mm it Between, and the diameter of phi B (Fig. 2-1) of protruding shaft 21 need to be less than the aperture Φ A of axis hole 11 and both gaps are substantially equal to 0.1mm, it can be represented with below equation:

Φ A=Φ B+0.1mm, 2.1mm≤Φ A≤4.1mm

In summary, the utility model mainly provides the seesaw button after a kind of improvement, projects and produces using mould Integrally formed seesaw lid and pedestal, and the section intersected with die parting line is formed in the protruding shaft of pedestal, allow and dividing mould to produce online Raw burr will not interfere with rotation of the protruding shaft between axis hole and allow seesaw button card key, in short, seesaw of the present utility model is pressed Key possesses following advantages:

1. the precision of mould processing is not required to too high.

2. projecting condition during injection molding need not be too high.

3. burr caused by axle need not reject during assembling product.

Above-mentioned detailed description is to illustrate for a kind of preferably possible embodiments of the utility model, only the embodiment It is not intended to be used to limit claim of the present utility model, under all other skill spirits without departing from disclosed in the utility model The equivalent changes and modifications change completed, is intended to be limited solely by the claim that the utility model is covered.
