Abstract
The utility model relates to a waterproof structure of a metal detector main machine, and the structure comprises: a panel; an aluminium alloy housing arranged on two sides of the panel; an aluminium alloy cover arranged on a top portion of the aluminium alloy housing; the main machine arranged in a frame enclosed by the panel, the aluminium alloy housing, and the aluminium alloy cover; and also two O-shaped rubber rings; the two O-shaped rubber rings are arranged on the panel contacted with the aluminium alloy cover; the aluminium alloy cover is provided with two holes corresponding to the two O-shaped rubber rings; the aluminium alloy housing and the aluminium alloy cover are in a threaded connection; and beneficial effects of the structure are that the two O-shaped waterproof rubber rings of an end cover can ensure a waterproof surface to carry uniform load through a spirally screwed mode, the panel, a bottom cover and the main machine are connected into a whole body after being assembled, and waterproof purpose of the main machine is obtained.
Description
Technical field
The utility model relates to a kind of metal detector, relates in particular to the waterproof construction of this metal detector main frame.
Background technology
Metal detector often need to be at underwater work.
But metal detector can not solve following problem in the prior art:
1, the distortion of plastic cement causes the anti-water surface not on a surface level;
2, the precompressed of rubber band excessively pine cause the location mobile, cause that waterproof is bad;
3, the precompressed tension of rubber band causes and exceeds yield strength, loses restoring force when high temperature or low temperature;
4, the discontinuity of the anti-water surface.
Summary of the invention
The utility model technical issues that need to address have provided a kind of waterproof construction of metal detector main frame, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: panel; Settle Al alloy shell in described panel both sides; Settle the aluminium alloy lid on described Al alloy shell top; Main frame is placed in the frame that is surrounded by panel, Al alloy shell and aluminium alloy lid; Also comprise: two road O shape rubber bands; Described two road O shape rubber bands are settled on the panel that contacts with the aluminium alloy lid; Cover two holes corresponding with two road O shape rubber bands of making at described aluminium alloy; Described Al alloy shell is to be threaded with the aluminium alloy lid.
Compared with prior art, the beneficial effects of the utility model are: owing to pass through two road O shape waterproof rubber bands of end cap, evenly assemble rear panel, bottom and main frame and link into an integrated entity to guarantee the stressed of the anti-water surface in the mode that spiral is tightened, reach the waterproof purpose of main frame.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: panel 1; Settle Al alloy shell 2 in described panel 1 both sides; Settle aluminium alloy lid 3 on described Al alloy shell 2 tops; Main frame is placed in by in panel 1, Al alloy shell 2 and aluminium alloy lid 3 frames that surround; Also comprise: two road O shape rubber bands 4; Described two road O shape rubber bands 4 are settled with aluminium alloy and are covered on 3 panels that contact 1; Make two hole (not shown) corresponding with two road O shape rubber bands 4 at described aluminium alloy lid 3; Described Al alloy shell 2 is to be threaded with aluminium alloy lid 3.
The selecting of rubber band in the utility model:
1) the material selection environmental protection of rubber band, nonpoisonous and tasteless, high temperature resistant, cold-resistant, waterproof, anti-aging;
2) shape of rubber band is selected O shape, and the cross section is circular, and that this shape advantage is to process is easy, cost is low;
3) hardness of rubber band is selected 40 degree, can be when locking when being fit to assembling with the shape distortion in space, again can be under water indeformable under 10 meters the pressure, thus reach the effect of O shape rubber band waterproof.
The position of O shape rubber band in the utility model:
O shape rubber band is between panel and aluminium alloy lid.
The effect of O shape rubber band in the utility model:
Before the assembling, two road O shape waterproof rubber bands are pre-aligned on panel,, the surface of O shape rubber band is contacted by line with other part be transitioned into the face contact, thereby reach the waterproof purpose by with instrument screw thread being screwed through the lid of aluminium alloy and shell.
The threaded engagement of Al alloy shell and lid in the utility model:
The uniform stressed of O shape rubber band is the key point of the water resistance of product, and the threaded engagement of Al alloy shell and lid then makes O shape rubber band at the radially uniform stressed of screw thread, has avoided warping and fold of O shape rubber band.
The mode that screws of aluminium alloy lid in the utility model:
In order to control the stressed tension of O shape rubber band with excessively loose, at first locate Al alloy shell, made the hole of two diameter 2mm at the lid of aluminium alloy, 180 ° of distributions, and make and to screw anchor clamps, guaranteed that O shape rubber band both under the state of micro-deformation, can keep again restoring force to play waterproof action, avoid simultaneously product appearance impaired, reached the waterproof purpose of metal detector main frame.
