Technical field

The utility model relates to a kind of assembled machine table, especially the assembled machine table that refers to a kind of button pin-jointed structure, this assembled machine table utilizes a housing push rod earlier, one housing is pushed on the assembly platform on a housing delivery track, utilize an inside casing push rod again, one inside casing is pushed on the sloping platform on an inside casing delivery track, this inner tilt frame is had angle behind the θ, utilize an inclination push rod, one outside of this inside casing is pushed into an inboard of this housing with this angle theta, then make the lead angle of two compression leg push rods, one bottom edge, be compressed to the two corresponding outsides of this inside casing respectively, and being urged respectively on its two corresponding outside is directed in the pivot hole corresponding on this housing, and then quickly and accurately this housing and inside casing are assembled into the pin-jointed structure of this button, therefore can effectively increase the pivot joint tightness between this inside casing and housing, significantly promote the product fine rate of the pin-jointed structure of this button.

Background technology

Along with the very fast progress of science and technology, computer has been widely used in various occasions, for the user as information traffic, commercial intercourse, client's contact, document is handled and the usefulness of computer graphics, and keyboard be user's operating computer indispensable input unit; General keyboard is staggered by a plurality of buttons and forms, see also button shown in Figure 1 10, respectively by a pin-jointed structure 11, one underframe 12, one keycap 13, one elastomer 14 and a circuit board 15 combine, wherein this pin-jointed structure 11 is made up of a housing 111 and an inside casing 112, this housing 111 is the flat hollow framework of a plastic material, be provided with an accommodation space 116 (as shown in Figure 2) in it, its two corresponding inboard is provided with a pivot hole 114 (as shown in Figure 2) respectively symmetrically, this inside casing 112 is the flat lamellar body of a plastic material, its middle position offers a perforation 113, its two corresponding outside is provided with a pivot 115 (as shown in Figure 2) respectively symmetrically, respectively this pivot 115 is corresponding with this pivot hole 114, and can penetrate and be positioned in this pivot hole 114, this inside casing 112 can be hubbed in this housing 111, and form this pin-jointed structure 11, the end face middle position of this underframe 12 is provided with an opening 121, its end face periphery is provided with a plurality of setting elements 122, make the bottom surface of this pin-jointed structure 11 can be positioned to the end face of this underframe 12 by these setting elements 122, this keycap 13 is located at the end face of this pin-jointed structure 11, the bottom surface of this elastomer 14 is fixedly held on this circuit board 15, its end face then passes the perforation 113 of opening 121 and this inside casing 112 of this underframe 12, and is connected to the bottom surface of this keycap 13; So, when this keycap 13 is subjected to user's application of force and pushes, can move towards the direction of this circuit board 15, and oppress this elastomer 14 generation distortion, the pin that this elastomer 14 is triggered on these circuit boards 15, and then make this circuit board 15 send out corresponding signal, as user when no longer the application of force is pushed, this elastomer 14 can make this keycap 13 get back to original position, and no longer trigger the pin on this circuit board 15 by the spring return original state of self; What deserves to be mentioned is that in the process that this keycap 13 moves back and forth, this pin-jointed structure 11 can make the moving track of this keycap 13 remain in the predetermined scope, and the unlikely application of force because of the user is offset out original position.

From the above, general manufacturer can use traditional assembled machine table when aforesaid housing 111 and inside casing 112 are assembled into pin-jointed structure 11; See also traditional assembled machine table 16 shown in Figure 2, this assembled machine table 16 is provided with two stay bolt elements 161, and this two stay bolts element 161 is symmetrical, and is respectively equipped with an inclined-plane 162 on each stay bolt element 161; In the assembling process of this pin-jointed structure 11, at first this housing 111 is placed in the position of contiguous apical margin on this two stay bolts element 161, two corresponding inboards of this housing 111 are resisted against respectively on the inclined-plane 162 of these two stay bolts element, 161 contiguous apical margins, and this housing 111 imposed down a pressure, at this moment, because this housing 111 is the rubber-like plastic material, therefore, this housing 111 two corresponding inboard can be along the inclined-plane 162 of correspondence to lower slider, make the outside gradually stay bolt in both sides of this housing 111 be out of shape, and the accommodation space 116 of this housing 111 is expanded outwardly, then, again this inside casing 112 is inserted in the accommodation space 116 after the expansion, make this inside casing 112 be positioned at the position of these two stay bolts element, 161 apical margins, and make pivot 115 on it be positioned in position respectively corresponding to these pivot holes 114, stop this housing 111 is imposed down pressure, at this moment, this housing 111 can be subjected to the influence of self elasticity of plastics, and its both sides are resetted to internal strain gradually, make that respectively this pivot 115 penetrates and is positioned in this pivot hole 114, and then this inside casing 112 not only is placed in this accommodation space 116, and can be hubbed in this housing 111, and form this pin-jointed structure 11.

Yet, because traditional assembled machine table 16 is when the aforesaid pin-jointed structure 11 of assembling, be earlier by force with after this housing 111 stay bolts distortion, again this inside casing 112 is inserted in this housing 111, this inside casing 112 can after resetting, be hubbed in this housing 111 in these housing 111 distortion, therefore, when in case this housing 111 excessively follows the string because of stay bolt, this inside casing 112 will be because of the excesssive gap of itself and housing 111, and in housing, come off easily, the problem that causes the product fine rate to decline to a great extent, so not only can have influence on the overall construction intensity of the button 10 of aforementioned keyboard, even can have influence on the normal operation of aforementioned keyboard, make it be triggered and to send signal effectively, and cause user's inconvenience and puzzlement.

Because aforesaid traditional assembled machine table 16 is when the aforesaid pin-jointed structure 11 of assembling, has the aforementioned shortcoming that makes housing 111 excessive stay bolts easily and be out of shape, therefore, how to design a kind of assembled machine table of innovation, decapacitation is assembled into a housing and an inside casing outside the pin-jointed structure of one button quickly and accurately, still can effectively solve the problem that inside casing comes off easily in housing, promptly become the important topic that the utility model is inquired in this desire.

In view of this, for improving the shortcoming of traditional assembled machine table, the designer is through the permanent research and experiment of making great efforts, finally development and Design goes out the assembled machine table of a kind of button pin-jointed structure of the present utility model, in the hope of passing through the utility model, increase inside casing in this button pin-jointed structure and the pivot joint tightness between housing effectively, and reach the effect of the product fine rate of the pin-jointed structure that promotes this button.
