Embodiment
At first see also Fig. 1 to Fig. 5; the diaphragm of the utility model one LCD screen that preferred embodiment provides is changed structure 10; it consists predominantly of a housing 20, a fixed head 30, a Liquid Crystal Module 40, a Trackpad 50 and two pull handles 60, is to be used for changing a diaphragm 70.
This housing 20 is made up of one first housing 22 and one second housing 24; This first housing 24 and respectively be to be provided with one second elastic parts 26 between this pull handle 60 wherein, respectively these second elastic parts, 26 1 ends are located at this first housing 24, and the other end is located at this pull handle 60, carries out involution for this pull handle 60 respectively; This second housing 24 is to have an opening 25 in the top side, and this Liquid Crystal Module 40 can the part be revealed in the external world via this opening 25, for display message; This second housing 24 is provided with a waterproof foam 28 in bottom side and this Trackpad 50 laps, in order to seal the space between this second housing 24 and this Trackpad 50, this waterproof foam 28 can be fitted tightly, to reach the purpose of waterproof with this diaphragm 70.This second housing 24 has a long and narrow opening 29 in side, wears for this diaphragm 70.
This fixed head 30 is fixedly arranged on this first housing, 20 top sides, and has some perpendicular positionings portion 32; Wherein these perpendicular positioning portions 32 are laid in this fixed head 30 two opposite sides respectively.
This Liquid Crystal Module 40 is located at this fixed head 30 top sides, and this Trackpad 50 covers in the top side of this Liquid Crystal Module 40, and has some traversing location divisions 52, some perpendicular positionings hole 54 and some guide rails 56; Wherein these traversing location divisions 52 are positioned at this Trackpad 50 two opposite sides; These perpendicular positioning holes 54 are positioned at this Trackpad 50 other two opposite sides, use for these perpendicular positioning portions 32 and wear, and respectively this perpendicular positioning portion 32 is arranged with one first elastic parts 58, this this fixed head 30 of first elastic parts, 58 1 end contacts respectively, this Trackpad 50 of other end contact carries out involution for this Trackpad 50; These guide rails 56 are positioned at this Trackpad 50 in end face and contiguous ora terminalis place, in order to limit the position of this diaphragm 70.
This two pull handle 60 is located at this first housing, 22 both sides respectively, and can be along this first housing 22 in a release position P1 and displacement between the locking position P2.This two pull handle 60 is positioned at the two opposite sides of this Trackpad 50, and has some grooves 62 and a pulling part 64 respectively; Wherein these grooves 62 are to wear for these traversing location divisions 52; These traversing location divisions 52 can make this two pull handle 60 can drive this Trackpad 50 along these perpendicular positioning portion 32 displacements along these groove 62 displacements; These pulling part 64 usefulness are operated these pull handles 60 for the user.
This diaphragm 70 is located between this Trackpad 50 and this second housing 24; And can pass the opening 29 of these second housing, 24 sides, and cover in this Trackpad 50 surfaces.
Via said structure, under the state of general normal use, this two pull handle 60 can be positioned at this locking position P2, and this diaphragm 70 is between this Trackpad 50 and this second housing 24, and this waterproof foam 28 of contact, (as shown in Figure 4).When user's desire is changed this diaphragm 70, be moved to this release position P1 laterally as long as pull this two pull handle 60; This two pull handle 60 can be toward the horizontal direction displacement, and simultaneously, by these grooves 62, the traversing location division 52 of ordering about this Trackpad 50 is toward vertical direction displacement (shown in Fig. 6 A to Fig. 6 C).Thus, this Trackpad 50 can be relatively away from this second housing 24, makes the space increase (as shown in Figure 7) of 28 of waterproof foams of this Trackpad 50 and this second housing 24, and removes the locking condition of this diaphragm 70; The user just can take out the opening 29 of this diaphragm 70 from this second housing 24.
When if user's desire is installed this diaphragm 70, as long as the opening 29 of this diaphragm 70 from this second housing 24 inserted; When the guide rail 56 of these diaphragm 70 contacts, represent that promptly this diaphragm 70 is to insert fully to this Trackpad 50; At this moment; the user is as long as pulling this two pull handle 60 again in this locking position P2; respectively this second elastic parts 26 can order about respectively that this pull handle 60 carries out involution; 58 of these first elastic partss order about this Trackpad 50 and carry out involution; make these Trackpad 50 meetings relatively near this second housing 24; the space that the waterproof foam of this Trackpad 50 and this second housing (24) is 28 can dwindle (as shown in Figures 7 and 8) gradually; this waterproof foam 28 is pasted again support to cover, and finish the installation work (as shown in Figure 9) of this diaphragm 70 in this Trackpad 50.
Thus, the user operates according to above-mentioned steps, does not need by instrument, and is single with the free-hand purpose that just can reach quick this diaphragm of replacing; If user's desire is dismantled this diaphragm, as long as according to the sequence of steps reverse operating, the purpose of fast this diaphragm of quick-detach.
In sum, more converting mechanism and installing that the utility model is simplified diaphragm are easy, and be single with the free-hand operation that just can install or dismantle; Moreover it is little compared to existing person that the utility model is subjected to the restriction of environment space, is easy to the operation of installing or dismantling.Thus, the utility model can overcome existing person's shortcoming, has the characteristic of installing fast and dismantling.In addition, the utility model is applicable to the diaphragm that uses general material, but not needs to use the diaphragm of special substance, and is comparatively cheap on maintenance cost, has the characteristic that reduces cost.
The utility model is taken off disclosed constituent components among the embodiment in preceding, only is for illustrating, and is not the scope that is used for limiting this case, the alternative or variation of other equivalent elements, and the claim that also should be this case contains.
