Embodiment
For convenience of description, following embodiment, identical assembly is represented with identical label.
Shown in Fig. 3,5, the rotation reassembling type keycap of the utility model one preferred embodiment and bridge formation combined mechanism are mounted on the word key device 20, this word key device 20 has elastic component 24, device that the locating unit of being made up of a location-plate 22 and a circuit board 23 21, is placed in these positioning unit 21 end faces at the keycap 30 on these elastic component 24 tops, and a bridge formation 40 that is installed between this keycap 30 and this positioning unit 21.
This location-plate 22 has a first end 221 and a second end 222 that is reverse, one is positioned at this second end 222 and towards the top punching out and be down L shaped leading and move piece 223, and is arranged at a projection 224 and the two curved arc blocks 225 of this first end 221 and space.
This keycap 30 comprises that one touches the bottom surface 31 of this elastic component 24, is arranged at a first end 311 of this bottom surface 31 and two pivot pieces 32 of space, and is arranged at a second end 312 of this bottom surface 31 and two guide blocks 33 of space.
Each pivot piece 32 respectively has a sealing pivot hole 321.
Each guide block 33 respectively has one from these bottom surface 31 vertical growing and L-shaped binding wall 331, one from the open end face of this binding wall 331 curved establish be parallel to this bottom surface 31 lead wall 332, and one leads wall 332 and this bottom surface 31 by this binding wall 331 and this and is cooperated to form and have the open end and the leading of a blind end that are reverse and move space 333; And this open end is towards this second end 312.
Preferably, this guide block 33 also has one and is arranged at the lead angle 335 that this leads an open end face 334 of wall 332.
This bridge formation 40 comprises one first framework 50 and one second framework 60 that is pivoted mutually and can swings.
As Fig. 3, shown in 4, this first framework 50 has a body 51, be arranged at the containing hole 52 of this body 51 for ccontaining this elastic component 24, two connecting blocks 53 that parallel that extend outwardly from a first end 511 of this body 51, grow and can enter respectively the 2 first pivot posts 54 in this two sealings pivot hole 321 in the same way along its vertical direction from the open end of this two connecting block 53, be arranged at a second end 512 of this body 51 and insert this and lead to move in the piece 223 and can be subject to this and lead the one first displacement post 55 that moves piece 223 linear displacements, and be one the 3rd side 513 of reverse setting and two pivots 56 that this first pivot post 54 is extended and be parallel in one the 4th side 514 from this body 51.
Preferably, this 2 first pivot post 54 respectively has a lead angle 541.
Shown in Fig. 3,5, this second framework 60 has a body 61, one to be arranged at this body 61 ccontaining and be formed with two containing holes 62 of side levers 63 at interval for this first framework 50, be arranged at this two side lever 63 respectively and can be sheathed on this two pivot 56 outer so that this first build bridge 50 with this second two pivot holes 64 of 60 pivots knot of building bridge, and be arranged at this two side lever 63 respectively and be a reverse first end 631, the one second pivot post 65 and the 2 second displacement posts 66 of a second end 632.
But this second pivot post 65 is to urge to insert between this projection 224 and this two block 225 and the original position rotation.
This 2 second displacement post 66 is to insert this respectively two to lead to move in the space 333 and can paste and touch this and lead wall 332 linear displacements.
During assembling, be to be ready for this positioning unit 21 and this elastic component 24 earlier, insert this and lead and move piece 223 the first displacement post 55 of this first framework 50 is sliding earlier again, the second pivot post 65 of this second framework 60 is urged between this projection 224 and this two block 225, secondly, this keycap 30 is placed on this elastic component 24, the application of force presses down this second end 312 then, then can make this 2 second displacement post 66 enter this from the open end of this guide block 33 leads and moves in the space 333, and design by this lead angle 335, can make that this 2 second displacement post 66 is quicker to be entered this swimmingly and lead and move in the space 333, at last, bestow this keycap 30 1 revolving forces, sealing pivot hole 321 turning sets of this two pivots piece 32 are located at outside this 2 first pivot post 54, and, then can make these two sealings pivot hole, 321 quicker rotation sets swimmingly outside this 2 first pivot post 54 by the design of this lead angle 541; So just can finish the assembling operation of this keycap 30 and this bridge formation 40 and this positioning unit 20.
Shown in Fig. 3,6, during dismounting, need only be with these keycap 30 backward rotation, then this two sealings pivot hole 321 can break away from this 2 first pivot post 54, this 2 second displacement post 66 can break away from this from the open end of this two guide block 33 and leads and move space 333 simultaneously, so, just finished the field-strip of this keycap 30 and this bridge formation 40.
What deserves to be explained is, a pivot piece 32 and a sealing pivot hole 321 and one first pivot post 54 only are set, also can have identical operating characteristic.
As shown in Figure 7, the utility model second preferred embodiment is that two pivot pieces 32 at this keycap 30 respectively are provided with a radially open pivot hole 323, design whereby, when this keycap 30 of rotation, also can make this two radially open pivot hole 323 be pivoted, break away from this first framework 50 and be the 2 first pivot posts 54 that are provided with in the same way, and then can conveniently finish assembling, the field-strip of this keycap 30 and this bridge formation 40.
Via above explanation, can again effect of the present utility model and advantage be summarized as follows:
One, the utility model is to adopt rotation mode to finish the assembly and disassembly operation of this keycap 30 and this bridge formation 40, just can not finish assembly and disassembly operation with this bridge formation 40 because must not hale, suppress this keycap 30, so have the effect and the advantage that can effectively reduce these 40 spoilages of building bridge.
Two, because the utility model is the sealing pivot hole 321 and this 2 first pivot posts, 54 pivots knot by two pivot pieces 32 of this keycap 30, so vertical this keycap 30 of getting it right executes one to upper pulling force, this keycap 30 can not break away from this bridge formation 40 yet and then can have high drawing operating characteristic, makes this keycap 30 have the effect and the advantage of high stability relatively.
Though the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, under the situation that does not break away from the utility model spirit, also can make the variation and the modification of various equivalences, therefore, as long as variation, the modification to the foregoing description all will drop in the scope of the utility model claims in connotation scope of the present utility model.
