Description

Technical Field

[0001] The utility model relates to the technical field of container design, in particular to a container structure capable of reducing the welding strength of a butt weld. Background Art

[0002] As we all know, liquids expand when heated and contract when cooled. This is because the average thermal motion speed of liquid molecules is different at different temperatures, and the volume of the liquid is related to the average thermal motion speed of the molecules.

[0003] After the welded container is filled with water, stress will be generated on the container wall due to the influence of factors such as the static pressure of water and possible temperature changes. These stresses may cause fatigue damage to the container material, especially in stress concentration areas such as welds.

[0004] The weld has fatigue strength because the defects and stress concentration areas generated during the welding process make the welded joint susceptible to fatigue damage. As time goes by, the bearing capacity of the weld will be insufficient, causing the container seal to fail and become incapable of normal use. Utility Model Content

[0005] The utility model aims to provide a container structure with reduced welding strength of the weld, aiming to solve the problem of insufficient bearing capacity of the weld of the container in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a container structure that reduces the welding strength of the weld, including: a container body, a sealing piece connected to the end of the container body, and the outer edge of the sealing piece is connected to the inner wall of the container body through a weld; a support part is connected between the end of the container body and the outer side wall of the sealing piece.

[0007] Furthermore, a supporting edge is vertically provided on the outer peripheral edge of the sealing member, and the supporting portion is connected to the supporting edge.

[0008] Furthermore, the support portion is a convex point formed by extruding from the outer side of the end of the container body to the outer side of the support edge, or is a convex point formed by extruding from the inner side of the support edge to the inner side of the end of the container body.

[0009] Furthermore, at least four support parts are provided, and are arranged around the outer peripheral surface of the end of the container body or the inner peripheral surface of the support edge at intervals.

[0010] Furthermore, the convex points are hemispherical convex points, conical convex points, rectangular columnar convex points, polygonal columnar convex points or cylindrical convex points.

[0011] Furthermore, the supporting edge and the sealing member are an integral structure.

[0012] Furthermore, the support portion is a connecting rib that protrudes from the inner side wall of the end portion of the container body and is extruded and connected to the outer side wall of the supporting edge, or is a connecting rib that protrudes from the outer side wall of the supporting edge and is extruded and connected to the inner side wall of the end portion of the container body.

[0013] Furthermore, the support portions are vertically spaced apart in at least two rows between the end of the container body and the outer side wall of the support edge.

[0014] Furthermore, the container body is a cylinder or a cube.

[0015] Furthermore, the shape of the sealing member is adapted to the shape of the end of the container body.

[0016] The utility model provides a container structure with reduced welding strength of the weld. Compared with the prior art, the end of the container body is connected with a sealing piece, and the outer peripheral edge of the sealing piece is connected to the inner wall of the container body by a weld. By connecting a support part between the end of the container body and the outer side wall of the sealing piece, the load borne by the sealing piece is transferred from the weld to the support part, which can effectively reduce the fatigue load of the weld and improve the overall load strength of the container body.

[0026] The present invention is described in detail below in conjunction with specific embodiments.

[0027] In the present utility model, when directional words appear, they are used to facilitate the description of the utility model and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present utility model.

[0028] In the present invention, unless otherwise specified and limited, when terms such as "disposed on", "connected" and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Embodiment 1

[0030] like Figure 1 and Figure 2 As shown, a container structure for reducing the welding strength of the weld seam includes a container body 10 and a sealing member 20. The container body 10 is a cylinder or a cube, and the shape of the sealing member 20 is adapted to the shape of the end of the container body 10.

[0031] The sealing member 20 is connected to the end of the container body 10 , and the outer peripheral edge of the sealing member 20 is connected to the inner wall of the container body 10 via a weld 11 .

[0032] In order to prevent the weld 11 from growing longer and causing insufficient bearing capacity at the weld 11, a support portion 12 connected to the outer wall of the sealing member 20 is provided at the end of the container body 10, so that the load borne by the sealing member 20 is transferred from the weld 11 to the support portion 12, which can effectively reduce the fatigue load of the weld 11 and improve the overall load strength of the container.

[0033] In this embodiment, a support edge 21 is vertically provided on the outer peripheral edge of the sealing member 20, and the support portion 12 is connected to the support edge 21. The support edge 21 and the sealing member 20 are an integral structure, which is convenient for processing and forming.

[0034] Specifically, the support portion 12 is a convex point 121 formed by extruding from the outer side of the end of the container body 10 to the outer side of the support edge 21, or is a convex point 121 formed by extruding from the inner side of the support edge 21 to the inner side of the end of the container body 10, thereby forming a concave point on the support edge 21 or the end of the container body 10. Through the connection and cooperation of the concave and convex points, the connection and supporting strength between the sealing member 20 and the end of the container body 10 is strengthened.

[0035] The bump 121 structure can be a hemispherical bump, a conical bump, a rectangular columnar bump, a polygonal columnar bump or a cylindrical bump.

[0036] Since the container body 10 is a cylinder or a cube, at least four support parts 12 are provided, and are arranged around the outer circumference of the end of the container body 10 or the inner circumference of the support edge 21 to meet the connection support strength between the sealing member 20 and the end of the container body 10.

[0037] Embodiment 2

[0038] like Figure 3 As shown, on the basis of the first embodiment, when the support portion 12 is a protrusion 121 structure, the number of vertical columns of the support portion 12 is increased, and the support portion 12 is provided with at least two columns vertically spaced between the end of the container body 10 and the outer wall of the support edge 21, thereby further improving the connection support strength between the sealing member 20 and the end of the container body 10.

[0039] In addition, the number of columns of the support parts 12 in the vertical direction can be determined according to the specific size of the container body 10 , so as to ensure the connection support strength between the sealing member 20 and the end of the container body 10 .

[0040] Embodiment 3

[0041] like Figure 4 and 5 As shown, the difference from the first embodiment is that:

[0042] The support portion 12 is a connecting rib 122 that protrudes from the inner side wall of the end of the container body 10 and is squeezed and connected to the outer side wall of the support edge 21, or is a connecting rib 122 that protrudes from the outer side wall of the support edge 21 and is squeezed and connected to the inner side wall of the end of the container body 10.

[0043] The connecting rib 122 is a whole structure, and is also formed by extrusion to form concave or convex strips on the end of the container body 10 or the side wall of the supporting edge 21 to form a supporting fit, so as to strengthen the connection support strength between the sealing piece 20 and the end of the container body 10.

[0044] Embodiment 4

[0045] like Figure 6 As shown, on the basis of the third embodiment, when the support portion 12 is a connecting rib 122 structure, the number of vertical columns of the support portion 12 is increased, and at least two columns of the support portion 12 are vertically spaced between the end of the container body 10 and the outer wall of the supporting edge 21, thereby further improving the connection support strength between the sealing member 20 and the end of the container body 10.

[0046] In addition, the number of columns of the support parts 12 in the vertical direction can be determined according to the specific size of the container body 10 , so as to ensure the connection support strength between the sealing member 20 and the end of the container body 10 .

[0047] It should be noted that if the container body 10 is an open structure, the sealing member 20 needs to be connected to one end of the container body 10 and the other end is equipped with an appropriate upper cover. If the container body 10 is a closed structure, the sealing members 20 need to be connected to both ends of the container body 10.

[0048] The utility model provides a container structure with improved fatigue strength of a weld 11. Compared with the prior art, a sealing member 20 is connected to the end of a container body 10, and the outer peripheral edge of the sealing member 20 is connected to the inner wall of the container body 10 via the weld 11. A support portion 12 is connected between the end of the container body 10 and the outer side wall of the sealing member 20, so that the load borne by the sealing member 20 is transferred from the weld 11 to the support portion 12, which can effectively reduce the fatigue load of the weld 11 and improve the overall load strength of the container body 10.

[0049] In the absence of conflict, the above-mentioned embodiments and features of the embodiments may be combined with each other.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
