Abstract

The utility model relates to a button waterproof construction. The mode of generally adopting the sealing washer on the market is waterproof, can only reach IP45 waterproof grade, and along with the live time becomes long simultaneously, the screw becomes flexible back sealing washer elasticity volume and diminishes, and ageing leading to equipment to lose dustproof and waterproof effect gradually of sealing washer itself in addition. The utility model discloses a last casing and lower casing of mutually supporting, last casing on form the waterproof turn strengthening rib of multichannel in inside, form the draw-in groove between the adjacent waterproof turn strengthening rib, the draw-in groove in set up waterproof button. Waterproof button be the silica gel material, it is installed in last casing through interference fit. The utility model provides a current structural strength little, the ageing back of sealing washer can't reach the problem of waterproof dustproof effect.

Description

Button waterproof construction

Technical Field

The utility model relates to a button waterproof construction improves, in particular to button waterproof construction of wisdom tourism tablet.

Background

Wisdom tourism tablet is one of the associated smart machine in "wisdom scenic spot", and its effect lies in utilizing new technologies such as cloud computing, thing networking, through internet/mobile internet, with the help of portable terminal internet surfing equipment, the information in aspects such as initiative perception tourism resource, tourism economy, tourism activity, tourist, in time release, let people can in time know these information, in time arrange and adjust work and tourism plan to reach the intelligent perception to various tourism information, the effect of facilitating the use. The mode of generally adopting the sealing washer on the market is waterproof, can only reach IP45 waterproof grade, and along with the live time becomes long simultaneously, the screw becomes flexible back sealing washer elasticity volume and diminishes, and ageing leading to equipment to lose dustproof and waterproof effect gradually of sealing washer itself in addition.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above-mentioned background art not enough, provide a button waterproof construction, solved the problem that current structural strength is little, can't reach waterproof dustproof effect after the sealing washer is ageing.

In order to solve the above problem, the utility model adopts the following technical scheme: the utility model provides a button waterproof construction, its characterized in that is including the last casing and the lower casing of mutually supporting, last casing on form waterproof turn strengthening rib of multichannel in inside, form the draw-in groove between the adjacent waterproof turn strengthening rib, the draw-in groove in set up waterproof button.

Waterproof button be the silica gel material, it is installed in last casing through interference fit. The dustproof and waterproof effect can be greatly improved.

The upper shell is fixedly connected with the lower shell through an ultrasonic process, the lithium battery and the circuit board are arranged in the upper shell and the lower shell, and the display screen is further installed on the outer surface of the upper shell. Go up the casing and utilize the basic size of reservation after the casing passes through ultrasonic bonding, can tightly withstand waterproof button through the strengthening rib of last casing, utilize elastic deformation to tightly push down the contact surface space to dustproof and waterproof effect has been improved greatly.

The lithium battery is installed and fixed in the groove position of the lower shell, and the circuit board is fixed on the three-point reinforcing rib salient points of the lower shell.

The three-point reinforcing rib salient points tightly support the waterproof button.

The utility model has the advantages that:

1. during assembly, after all the components are assembled, the components are fixed through an ultrasonic process, the processes of placing sealing rings and screwing are reduced, and the assembly process is greatly improved.

2. Tightly withstands waterproof button through waterproof turn strengthening rib after the ultrasonic bonding, utilizes elastic deformation to tightly push down the contact surface space, because the interference size of reserving, even after the ageing deformation of silica gel, also can quiet withstand waterproof button, can not lose waterproof function because of the silica gel is ageing, improved dustproof and waterproof effect greatly.

3. Utilize multichannel area of contact and turn curved groove structure on the casing, prevented the water and the dust of outside from getting into greatly, even fall into the water of certain degree of depth, also can effectually prevent to deposit gold equipment because of external pressure is too big.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

Referring to fig. 1 to 6, a button waterproof structure comprises an upper shell 1, a lower shell 2, a lithium battery 3, a circuit board 4, a waterproof button 5 and a display screen 6, wherein the lithium battery 3 is fixedly installed in an inner groove of the lower shell 2, the circuit board 5 is fixed on a three-point reinforcing rib bump 7 designed on the lower shell 2, the display screen 6 is fixedly installed on a display hole of the upper shell 1, the waterproof button 5 is fixedly installed on a waterproof reinforcing rib 8 of the upper shell 1, and the upper shell 1 is fixedly connected with the lower shell 2 through an ultrasonic process.

In this embodiment, the upper case 1 and the lower case 2 are made of ABS flame retardant material, and the injection molding process is used to ensure the dimensional stability of each batch of parts, and at the same time, the production efficiency is very high. Waterproof button 5 adopts the silica gel material, has both satisfied self required elastic deformation, guarantees the precision simultaneously, can also satisfy subsequent output requirement.

The utility model discloses go up the casing and utilize the basic size of reservation after the casing passes through ultrasonic bonding down, can tightly withstand waterproof button through the strengthening rib bump of casing down, utilize elastic deformation to tightly push down the contact surface space to dustproof and waterproof effect has been improved greatly.

The above description is only the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered by the present invention.
