Abstract
The utility model discloses a fastening and sealing structure for a metal container in the field of thermobatteries, which is characterized in that a cover (2) is positioned on an internal step of a housing (3), and a fastening snap ring (1) is positioned on the cover (2) and connected with the housing (3) through threads. A process hole is arranged on the fastening snap ring (1). Glue (5) is respectively arranged between the fastening snap ring (1) and the cover (2) and between the cover (2) and the housing (3). The outer circumferential surface of the cover (2) is in interference fit with the inner circumferential surface of the step part of the housing (3). The fastening and sealing structure for the metal container can avoid weld collapse and deformation of the housing produced by welding, has good sealing performance and high connecting strength and can bear larger magnitude overload. The fastening and sealing structure for the metal container can be used as the housings of the thermobatteries and the like, which need to reduce the weight of the containers, require good sealing performance and can adapt to the harsh mechanical environments.
Description
Technical field
The utility model relates to a kind of thermal cell field canister.
Background technology
As everyone knows, in the thermal cell field,, often select the little metal of density to replace the shell as canister such as stainless steel, for example aluminium alloy, titanium alloy for alleviating canister weight.And the price of titanium alloy is generally relatively more expensive, and for saving cost, normal aluminium alloy is as the shell of container.But in the welding of aluminium alloy, have that weld seam subsides, defective such as housing distortion and sealing difference.And stressed when simple welding can not be born high overload when the overload magnitude is big, may cover the situation that detaches housing.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of canister fastening seal structure is provided, and to overcome housing that prior art exists and cover deficiencies such as the housing distortion, the weld seam that exist subside when being connected, increases the intensity and the sealing that connect.
The technical scheme that its technical problem that solves the utility model adopts is: lid is positioned on the interior step of housing, and fastening snap ring is positioned on the lid, and is connected with housing by screw thread.
On fastening snap ring, fabrication hole is arranged.
Between fastening snap ring and lid, lid and housing, glue is arranged.
The outer circumference surface of lid and the inner peripheral surface of housing step part are interference fit.
Fastening snap ring upper surface flushes with the housing upper surface.
During use, lid is pressed in the housing, cementing on the external screw thread of fastening snap ring with internal thread engagement on the housing, plays the effect of sealing and fastening cover.
The beneficial effects of the utility model are can avoid the welding between housing and the lid fully, and increase sealing and the intensity of housing with the lid junction, easy and simple to handle, safety.
The utility model can be used as the shell of thermal cell etc. need alleviate container weight, and the field that requires good seal performance and can bear harsh mechanical environment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a fastening snap ring structure chart of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a lid structure chart of the present utility model.
Fig. 4 is shell structure figure of the present utility model.
Fig. 5 is the structure chart after the utility model combine and assemble.
1. fastening snap rings among the figure, 2. lid, 3. housing, 4. fabrication hole, 5. glue.
Embodiment
Embodiment of the present utility model: in Fig. 1, Fig. 2, fastening snap ring 1 should guarantee enough length of thread engagements, and in order to shorten length of thread engagement, external screw thread can be fine thread.On fastening snap ring 1, also have fabrication hole 4, when assembling precession screw thread, use.
In Fig. 3, the outer circumference surface and fastening snap ring 1 inner peripheral surface that cover 2 boss are interference fit, simultaneously enough shoulder heights should be arranged, two ends technology fillet or chamfering.
In Fig. 4, housing 3 inner peripheral surface sizes need and lid 2 cylindrical periphery size interference fit, include spacing technology step in the housing 3, and and fastening snap ring 1 between enough length of thread engagements are arranged, in order to shorten length of thread engagement, internal thread can be fine thread.
In installation diagram shown in Figure 5, stepped portions in lid 2 is pressed in housing 3 inner chambers, simultaneously fastening snap ring 1 screws in housing 3 gland 2, fastening snap ring 1 end face and housing 3 end face; After lid 2 was pressed onto the position, in its surperficial even spreading glue, the internal thread of the external screw thread of fastening snap ring 1, housing 3 and fastening snap ring 1 were tightened the also even spreading glue of back and lid 2 connecting portions all around.
