Description
Technical field
The utility model relates to the instrument accessory, specifically a kind of dismountable instrument housing.
Background technology
At present, generally adopt independent instrument to make up on the engineering machinery, instrument housing adopts irony housing or casting housing mostly, and generally adopts welding or rotary press modelling for the encapsulation of instrument housing, and its production cost and required equipment are relatively more expensive.Though this mode can reach sealing purpose, yet, when needing repairing, instrument can't open housing, often cause scrapping of instrument.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of dismountable instrument housing that guarantees sealing effectiveness and convenient disassembly.
The technical scheme that addresses the above problem is: the dismountable instrument housing that is provided comprises a cylindrical housing body and Biao Gai housing, special feature of the present utility model is that the outside of outer cover body port part is provided with a plurality of first projectioies, this first projection has the arc indent, the cambered surface axis of this arc indent and outer cover body axes intersect, these a plurality of first projectioies evenly distribute along the outer cover body periphery; Said table lid housing inboard is provided with a plurality of second projectioies, this second projection has the arc evagination, the cambered surface of the cambered surface of this arc evagination and the first protrusion arc indent matches, and after table covered housing and screws on outer cover body, the arc evagination of second projection was stuck in the arc indent of first projection; Said table lid housing also has an interior cascaded surface, is provided with sealing gasket between the interior cascaded surface of this table lid housing and the port surface of outer cover body.As long as will show during encapsulation to cover in the arc indent of first projection that second projection of housing screws in outer cover body.
The cambered surface of the above-mentioned first protrusion arc indent can be non-arc surface, but arc surface preferably.
The cambered surface axis and the outer cover body axis of above-mentioned arc indent preferably intersect vertically.
Above-mentioned sealing gasket is elastic rubber gasket preferably, is closely linked so that make outer cover body cover housing with table by elastic rubber, and can guarantees good sealing property.
The utility model will make outer cover body cover housing with table and separate owing to adopted the bayonet arrangement of indent and evagination arcwall face, as long as the rotation table covers housing.Yet the rotation table covers housing more before separation, and needed strength is big more, cancellation external force, the projection that outer cover body and table covers housing can automatically revert to the state of close fit again, has not only guaranteed sealing, and can effectively prevent vibration environment lower casing body with show to cover separating of housing.

Fig. 2 is the upward view that table covers housing among Fig. 1.
Fig. 3 is the vertical view of outer cover body among Fig. 1.
Fig. 4 is assembly figure of the present utility model.
Fig. 5 is the partial enlarged drawing of Fig. 4.
Embodiment
An embodiment of the present utility model such as Fig. 1, Fig. 2 and shown in Figure 3.Meter case body 1 is a cylindrical shape, and its upper port is the plane, and the outside of outer cover body port part is provided with four first projectioies 2, and they evenly distribute along the excircle of outer cover body, is mutually 90 °; First projection has arc indent 3, and the arc surface of this arc indent 3 is downward, the axis of the arc surface of arc indent and outer cover body intersect vertical axis.Table covers inboard, housing 4 lower end and is provided with four second projectioies 5, and they evenly distribute along the inner periphery that table covers housing, and second projection 5 has arc evagination 6, and the arc surface of this arc evagination 6 upwards.The arc indent 3 of first projection on the outer cover body and the arc evagination of second projection on the Biao Gai housing 6 constitute bayonet arrangement, after table covers housing 4 screw-in outer cover bodies 1, the arc evagination 6 that table covers second projection on the housing is stuck in the arc indent 3 of first projection on the outer cover body, will show to cover housing and outer cover body combines.Table covers housing 4 and also is provided with an interior step surface 7, and rubber gasket 8 is placed between this interior step surface 7 and outer cover body 1 upper surface.Firmly press down table during encapsulation and cover housing 4, the rotation table covers housing 4 then, the arc evagination 6 that table covers second projection on the housing is stuck in the arc indent 3 of first projection on the outer cover body, under the effect of rubber gasket elastic force, outer cover body 1 is covered housing 4 with table be closely linked.
When needing the maintenance instrument, as long as opposite spin table lid housing firmly, table cover the arc indent 3 of first projection on the second protruding 5 whiz outer cover bodies on the housing, can make and show to cover housing and separate with outer cover body.When also not leaving the arc indent 3 of first projection on the outer cover body, second projection 5 on the housing just cancels external force if cover at table, second projection 5 that table covers on the housing can slip back in the arc indent 3 of outer cover body first projection again automatically, is in original intimate-association state.So instrument that this structure is particularly suitable for using in vibration environment.
Consider that from the stressed intensity that evenly reaches housing of housing first projection 2 on the outer cover body is four at least.
Assembly of the present utility model such as Fig. 4, shown in Figure 5.Table cover housing 4 upper end open, seal with transparent organic glass table lid 9, table covers 9 pushes down rubber gasket 8, table cover 9 and sealing gasket 8 between the end face of the snap ring 10 of table cover housing upper end and outer cover body 1, second projection of showing on the cover housing 45 is stuck in the arc indent of outer cover body first projection 2.
