Description

Line control machine box body

Technical field

The utility model is related to line control machine technical field, specifically be a kind of touch line control machine box body.

Background technology

Touch line control machine box body generally comprises bottom shell plate, upper coverboard, touch panel and pcb board, states bottom shell plate and upper casing Board connects, and the touch panel is fixed on one side of the coverboard away from bottom shell plate, and existing touch line control machine button is generally tied Structure is；Key induced disk is drawn by spring from pcb board, then key induced disk through after upper coverboard directly and touch panel Inner surface push against, so as to receive the touch signal of the human hand on touch panel.In order to ensure the manual dexterity of button, generally will Spring design it is excessively high to ensure under the action of elastic force so that the inner surface of key induced disk and touch panel push against, so It there is following deficiency：The dynamics of key induced Pan Ding to touch panel is excessive, may result in touch panel deformation of unevenness, even Panel can come off with installing plate.

In addition, bottom shell plate and upper coverboard, generally using snapping connection, of the prior art snap connection dismantles more difficulty, Therefore a kind of buckle structure easy to disassemble need to be designed.

Furthermore buckle structure of the prior art has gap in access section, can be immediately seen buckle internal structure, this Sample, on the one hand, dust easily enters inside at gap, and dust is caused to pollute, in addition, one piece of concealed wire can be visually formed, Influence product appearance.

Utility model content

The utility model aims to solve the problem that at least one in above-mentioned technical problem.

I.e. the technical problem to be solved by the utility model is to provide one kind can effectively avoid touch panel deformation with coming off Line control machine box body.

In order to solve the above technical problems, a kind of line control machine box body of the utility model, including bottom shell plate, upper coverboard, touch Panel and pcb board, the bottom shell plate and upper casing board connect, and the bottom shell plate and upper casing board connect after form accommodating chamber, institute It states touch panel and is fixed on one side of the coverboard away from bottom shell plate, the pcb board is fixed in accommodating chamber, is set on the pcb board There is spring, the end of the spring is equipped with key induced disk, and the upper coverboard is equipped with key-press mounting structure, the button installation Structure includes being located at coverboard towards the one side of pcb board and in the annular muscle of key induced Pan Weizhichu, the ring-type top rib end with Pcb board surface is against the wall surface of the ring-type muscle and upper coverboard forms the installing blind for accommodating key induced disk, the button sense It should coil and be pushed against with the bottom sidewall of installing blind, the outer end of the bottom sidewall of the installing blind and the inner surface of touch panel paste Tightly.

After adopting the above technical scheme, it has the following advantages that：Since the bottom sidewall of key induced disk and installing blind is supported Tightly, without directly being contacted with touch panel abutting, push against power and absorbed by upper coverboard, so as to avoid in the prior art due to effect The possibility that power on touch panel is excessive and deforms touch panel；Further, since the outer end of the bottom sidewall of installing blind It is adjacent to the inner surface of touch panel, is equivalent to touch panel and is contacted by the bottom sidewall of installing blind with touch panel, from Without influencing reception of the key induced disk to touch signal；Furthermore annular muscle reduces the key induced effect for folding protection Influence of other impurity to key induced disk.

Under the basis using above-mentioned technical proposal, there can also be following technical characteristic：

The thickness of the bottom sidewall of the installing blind is 2~3.5mm.Specifically, can be 2mm or The spirit of reception of the key inductive disks to touch signal can be so effectively ensured in 2.5mm or 3mm or 3.5mm Density.

The quantity of the key-press mounting structure is multiple, and the height of the annular muscle in multiple key-press mounting structures is equal.This Sample, annular muscle play the role of support, it is ensured that the uniformity of key induced disk, and ensure that upper coverboard is installed with pcb board Steadily.

Towards the one side of pcb board equipped with multiple positioning columns, the pcb board and in positioning column corresponding position on the upper coverboard Equipped with location hole, the location hole and positioning column grafting.In this way, positioning pcb board can be facilitated when pcb board is installed, carry High efficiency of assembling.

The madial wall of the upper coverboard is equipped with multiple grabs being used for pcb board clamping, and the upper coverboard is towards pcb board one Side is equipped with the hole post being spirally connected with pcb board, and edge and the grab of pcb board are clamped, are connected in the middle part of pcb board with hole post by screw It connects.In this way, the fixation that pcb board can be stablized is connected with screw by grab.

The buckle structure to cooperate is equipped between the bottom shell plate and upper coverboard, the buckle structure refers to the bottom case The internal face of plate is equipped with the first card slot, and the outside wall surface of the upper coverboard is equipped with the second card slot, and first card slot is towards upper casing The side wall of plate one end forms the first fixture block, and the side wall of second card slot towards bottom shell plate one end forms the second fixture block, and described first Fixture block and the second card slot are clamped, and second fixture block and the first card slot are clamped, and first card slot is close to the side of upper coverboard one end Wall surface is inclined surface or arcwall face, and the structure of first card slot is narrow for top width bottom.In this way, it is equipped on bottom shell plate and upper coverboard Fixture block, card slot and be mutually clamped, so as to ensure bottom shell plate and upper casing board connect it is firm, further, since the first card slot is close to upper The side wall surface of coverboard one end is inclined surface or arcwall face, and in dismounting, inclined surface or arcwall face can facilitate the second fixture block to depart from First card slot, so as to play effect easy to disassemble.

One end of first fixture block coverboard upward is equipped with convex block, and the wall surface of second card slot away from bottom shell plate be equipped with With the resigning step of convex block cooperation, the top of the convex block is pushed against with the step surface of resigning step.In this way, convex block and resigning step Cooperation so that cooperation is close, is not in one piece dark when in addition seeing from outside to inside from this entrance so as to avoid dust Line.

The outside wall surface of the upper coverboard is equipped with short slot, circumferentially extending of the short slot along upper coverboard.It is in this way, easy to disassemble The placement of instrument, so as to easy to disassemble.

The outside wall surface of the bottom shell plate is equipped with deep gouge, and side wall surface of the deep gouge away from upper coverboard one end is equipped with dismounting Force-application block, the interior sidewall surface of the dismounting force-application block is narrow in the dismounting force-application block bottom width for inclined-plane, the dismounting force-application block with The dismounting resigning mouthful stretched into screwdriver is formed between upper coverboard.In this way, extracting tool such as slotted point screwdriver is being torn open It when unloading, can be inserted at dismounting resigning mouthful, and dismantle the interior sidewall surface of force-application block as inclined-plane, slotted point screwdriver supports at inclined-plane It leans on, when manually bestowing certain prying force, dismounting force-application block plays the role of lever, and slotted point screwdriver causes the side wall of bottom shell plate Deformation, is mutually disengaged buckle structure, so as to easy to disassemble.
