For the purpose, technical scheme and the advantage that make the utility model is clearer, hereinafter will combine accompanying drawing that the embodiment of the utility model is elaborated.Need to prove that under the situation of not conflicting, embodiment among the application and the characteristic among the embodiment be combination in any each other.
Fig. 1 is the schematic perspective view of can of the terminal equipment of the utility model embodiment, and Fig. 2 is the longitudinal sectional view of can embodiment illustrated in fig. 1, and Fig. 3 is the local enlarged diagram of cutaway view shown in Figure 2.
Extremely shown in Figure 3 like Fig. 1; The can of the utility model embodiment mainly comprises the lower house 1 and upper shell 2 that snaps together the formation confined space; At lower house 1 and upper shell 2 contacted positions; Two housings all include outwardly directed edge, two edges width on the plane that lower house 1 and upper shell 2 are interlocked, and all the wall thickness than housing separately is big.Wherein the edge on the lower house 1 is lower edge 19, and the edge on the upper shell 2 is upper edge 29.
On top along 29 or one of them of lower edge 19 on, be provided with first groove 12 that caves in, the another one correspondence is provided with first boss 22 that is arranged in this groove 12 after lower house 1 fastens with upper shell 2.When lower house 1 is fastened with upper shell 2, in this first groove 12, be provided with, and this first sealing ring 4 be pressed in first groove 12 through this first boss 22 like Fig. 6 and first sealing ring 4 shown in Figure 7.The cross section of this first sealing ring 4, such as being generally circular or oval, the sealing ring in the cross section of other shapes also is applicable to this certainly.
As shown in Figure 3, this first groove 12 is positioned on the lower edge 19 in the present embodiment, and this first boss 22 is positioned on this upper edge 29.In other embodiment of the utility model, first groove 12 also can be arranged on the upper edge 29, and the first corresponding boss 22 is arranged on the lower edge 19.
On top along 29 or lower edge 19 on one of them, the week after fastening along lower house 1 and upper shell 2 upwards is distributed with at least two through holes 11; Be provided with lower house 1 and upper shell 2 on the another one accordingly and fasten the relative blind hole 21 of back and this through hole 11, these blind hole 21 embedded nuts or inner surface are provided with screw thread.Through from this through hole 11, inserting screw and utilizing screw thread or nut in the blind hole 21, can lower house 1 and upper shell 2 closely be linked together this screw-driving.
As shown in Figure 3, this through hole 11 is positioned on the lower edge 19 in the present embodiment, on top along being provided with and these through hole 11 corresponding blind holes 21 on 29.In other embodiment of the utility model, through hole 11 also can be positioned at upper edge 29 and corresponding blind hole is positioned on the lower edge 19.
Week after fastening along lower house 1 and upper shell 2, upwards this through hole 11 and corresponding blind hole 21 were arranged on the outside at edge separately, and first groove 12 and first boss 22 are arranged on the inboard at edge separately.Lower edge 19 and upper edge 29 also are respectively arranged with and cave in and groove opposite in the more lateral of this through hole 11 and blind hole 21.As shown in Figure 2, lower edge 19 is provided with second groove 13 in the more lateral of this through hole 11, and upper edge 29 is provided with the 3rd groove 23 in the more lateral of this blind hole 21.
When lower house 1 is fastened with upper shell 2, in the slit after this second groove 13, the 3rd groove 23 relative with this second groove 13 and lower house 1 and upper shell 2 fasten, perhaps second sealing ring 3 of " ten " font of T-shape is set.
Among the embodiment of the utility model, during close together between this second groove 13 and the through hole 11, this T-shape perhaps " ten " font second sealing ring 3 these through hole 11 places promptly be " one " font or in separated " one " font.To shown in Figure 5, second sealing ring 3 in the present embodiment is selected T-shape for use, and second sealing ring 3 of this T-shape is " one " font at through hole 11 places like Fig. 2.
On top edge 29 and lower edge 19 are positioned at the more lateral of second groove 13 and the 3rd groove 23, also are provided with protruding boss.Certainly, on top along 29 and lower edge 19 one of them boss is set and another boss is not set also is feasible.As shown in Figure 3; In the present embodiment; Lower edge 19 is provided with gives prominence to 29 second boss 14 with lower edge 19 upper surfaces and towards the upper edge; On top be provided with and give prominence to 19 the 3rd boss 24, and this second boss 14 is oppositely arranged after lower house 1 and upper shell 2 fasten with the 3rd boss 24 with upper edge 29 upper surfaces and towards the lower edge along 29.This second sealing ring 3 is arranged in the part in the slit after lower house 1 fastens with upper shell 2, is lived by this second boss 14 and 24 extruding of the 3rd boss.
Among the embodiment of the utility model; At this second boss 14 apart from the close together place between this through hole 11; This second boss 14 stretches out greater than half circumference of through hole 11 radiuses again; Be distribute continuously (therewith correspondingly, the 3rd boss 24 also is that correspondence is distributed on the upper edge 29 continuously) on the lower edge 19.
The embodiment of the utility model lower house 1 is cooperated the installation butt joint with upper shell 2 after, uses screw upper shell 2 and lower house 1 is linked together.Be full of whole spaces of first groove 12 in the lower house 1 because the fastening force of screw through first boss, 22 extruding, first sealing ring 4 on the upper shell 2, makes it that strain take place, form first sealant.And the fastening force of screw makes lower edge 19 and upper edge 29 push second sealing ring 3; And; The 3rd boss 24 through on second boss 14 on the lower house 1 and the upper shell 2 further pushes second sealing ring 3; Make second sealing ring, 3 further strains, thereby guarantee that the slit between lower edge 19 and the upper edge 29 can fully seal up, and forms second sealant.
The embodiment of the utility model, lower house 1 is cooperated the installation butt joint with upper shell 2 after, whole for having the oblate cylinder shape of outer, whole zero parts at boat-carrying Big Dipper terminal can be positioned in the formed confined space of lower house.
The embodiment of the utility model has the sealing ring of two kinds of varying cross-section shapes through employing; And the position of groove reasonable in design and boss and size; Make two sealing rings in upper and lower casing butt joint and use screw and will go up lower house and be connected to one when whole; Obtain enough matching external pressure distortion, form two and prevent that press water from getting into the compressive resistance watertight seal of enclosure interior, can effectively protect whole zero parts of enclosure interior.
Among the embodiment of the utility model; The fastening quantity that goes up the screw of lower house can be selected 4 ~ 8 pairs preferably for use; Make described two sealing rings guarantee to obtain enough matching external pressure distortion, can adapt to the application of all kinds end product of different oblate cylinder shape diameters.Certainly, other quantity also are feasible.
Simple in structure, the low preparation cost of the utility model does not re-use the traditional handicraft of fluid sealant embedding, assembly method simple and fast, high efficiency, and good airproof performance.Easy to use and the maintenance of the embodiment of the utility model, install and remove easy to operate, can guarantee the reliability that seals.The embodiment of the utility model is convenient to standardization and is made, and applicability is wide, is beneficial to apply.
Though the execution mode that the utility model disclosed as above, the execution mode that described content just adopts for the ease of understanding the utility model is not in order to limit the utility model.Technical staff under any the utility model in the technical field; Under the prerequisite of spirit that does not break away from the utility model and disclosed and scope; Can do any modification and variation what implement in form and on the details; But the scope of patent protection of the utility model still must be as the criterion with the scope that appending claims was defined.
