Description

The computing machine waterproof casing

Technical field

The present invention relates to portable integrated computing machine, be specifically related to the casing of the portable integrated computing machine that in outdoor rugged surroundings, uses, more particularly, relate to a kind of portable integrated calculating function normal waterproof casing that uses under water or in the rainwater environment that makes.

Background technology

In the prior art, computing machine all needs to be placed in the local preferably use of environmental aspect usually, but along with requirements of one's work, as field study, field survey, need such as undersea detection are in the outdoor work of carrying out, need that all computing machine is carried to these local cooperations and carry out work, to increase work efficiency, though, also there is notebook computer can be used to carry out using now, but the water resistance of this computer is poor, requirement height to working environment, be used for waterproof though there are some portable integrated computing machines between two casing joint faces of casing, also to be provided with O-ring seal, but its water resistance still is difficult to be competent at the request for utilization under outdoor inclement weather, particularly needs computing machine is carried to when using under water, and existing computing machine then can't be realized.

Summary of the invention

The technical problem to be solved in the present invention is, a kind of computing machine waterproof casing is provided, the integrated computing machine that adopts this casing to be assembled into, not only can in outdoor rainwater weather, use, and also can normally use placing it in the water of certain depth of water, satisfied people's computed demand under mal-condition.

The technical scheme that solves the problems of the technologies described above provided by the invention is as follows: a kind of waterproof casing that is used to being assembled into one computing machine of member, comprise upper and lower casing with ring-type edge, the ring-type edge of upper and lower casing fastens the back and links together by securing member, is provided with the waterproof construction of mutual interlock on the fastening adjacent surface of described upper and lower edge.

In above-mentioned waterproof casing, the waterproof construction of described mutual interlock can be provided with like this: extend collar flange on the ring-type edge of a housing therein, be provided with the annular recess that is used to admit described collar flange on the ring-type edge of another housing, collar flange inserts the waterproof construction that constitutes mutual interlock in the annular recess.

In above-mentioned waterproof casing, the waterproof construction of described mutual interlock can also be provided with like this: extend first collar flange on the ring-type edge of upper shell, on the ring-type edge of lower house, be provided with second annular recess that is used to admit described first collar flange, simultaneously, extend second collar flange on the ring-type edge of lower house, on the ring-type frame of upper shell, be provided with the annular recess that is used to admit described second collar flange, described first collar flange inserts the first road waterproof construction that constitutes mutual interlock in first annular recess, and second collar flange inserts the second road waterproof construction that constitutes mutual interlock in second annular recess.

Adopt waterproof casing provided by the invention, compare with the computing machine of existing portable integrated structure, has following advantage: one of interlock mutually or two flanges and groove are set between adjacent of two housings, can in groove, place O-ring seal, to go up, after lower casing fits together with securing member, flange can be pressed in the O-ring seal in the groove tightly and constitute in the groove together or the waterproof construction of the mutual interlock of twice, on the integrated computing machine that this casing of feasible employing is assembled into, composition surface between the lower house has better water resistance, can satisfy the requirement of under outdoor inclement weather, using this integrated computing machine, even the integrated computing machine that will adopt this casing to be assembled into is placed on when using, also has favorable waterproof property under water.

Embodiment

Embodiment one: the basic setup mode of the waterproof construction of the mutual interlock in the waterproof casing is as follows: extend collar flange on the ring-type edge of a housing therein, be provided with the annular recess that is used to admit collar flange on the ring-type edge of another housing, collar flange inserts the waterproof construction that constitutes mutual interlock in the annular recess.

Embodiment two: as Fig. 1, shown in Figure 2, above-mentioned set-up mode makes between the composition surface of two housings and has only constituted waterproof construction one, a preferable set-up mode as shown in Figure 2, on the ring-type edge 11 of upper shell 1, extend first collar flange 13, on the ring-type edge 21 of lower house 2, be provided with second annular recess 23 that is used to admit first collar flange 13, simultaneously, extend second collar flange 22 on the ring-type edge 21 of lower house 2, on the ring-type frame 11 of upper shell 1, be provided with first annular recess 12 that is used to admit second collar flange 22, on near frame, the base plate of lower house is provided with to connect use through hole, the employing securing member can with on,

lower house

1,2 link together; After upper and

lower casing

1,2 connected, first collar flange 13 inserted the first road waterproof construction that constitutes mutual interlock in second annular recess 23, and second collar flange 22 inserts the second road waterproof construction that constitutes mutual interlock in first annular recess 12;

The water resistance that can increase substantially casing behind the twice waterproof construction is set, after tested, adopt the casing with twice waterproof construction provided by the invention, can be in the normally use under water of 50 meters degree of depth, can also be according to using needs, have under the more high-intensity condition at housing, adopt identical occlusion structure that three roads or multiple tracks waterproof construction are set on upper and

lower casing

1,2, to adapt to worse working environment.

Embodiment three: the collar flange and the annular recess that are arranged in the above-mentioned housing can also be provided with like this: two collar flanges can be set on a housing, be provided with on another housing two with another housing on two annular recess that collar flange is corresponding, can constitute the twice waterproof construction too after two collar flanges and two annular recess interlocks.

Embodiment four: as Fig. 3, shown in Figure 4, because the inner space of portable integrated computing machine is little, and housing is in sealing state all, the heat that produces when the parts in the housing are worked is difficult to discharge, the present invention also is further improved the shell structure of this casing, can be on this casing,

lower house

1,2 base plates are near ring-type frame 11, have additional inwardly recessed ventilation groove 14 on the position of 21 corners, after being interconnected, many ventilation grooves 14 on the same housing constitute the ventilation and heat groove of a ring-type, the heat that device produced that is installed in the housing is being undertaken in the round-robin process by the ventilation and heat groove that is arranged in the housing, can be conducted to housing by metal shell and dispel the heat outward, make and calculate function steady operation for a long time.

When adopting being assembled into one of said machine casing computing machine, also should in annular recess, place the O-ring seal that matches with groove shapes.

Flange on the above-mentioned housing and can adopt one of following shape to realize: rectangle, triangle, trapezoidal, arc according to sealing needs and corresponding processing conditions with the shape of cross section of the groove of its interlock; Usually can adopt the rectangular shape of being convenient to process and seal shown in Figure 2 to realize.

The O-ring seal that will be arranged in groove for ease of the flange on when assembling housing compresses, and produces interference when eliminating assembling, makes flange be difficult to compress O-ring seal, and playing best sealing effectiveness, the height of flange should be less than or equal to the degree of depth with the groove of its interlock.
