Description

Technical Field

[0001] The utility model relates to the technical field of kitchen utensil handles, in particular to a kitchen utensil handle capable of preventing weld depressions from occurring during welding. Background Art

[0002] Common kitchen utensils such as soup spoons and spatulas all include a head and a handle. There are generally two molding methods: one is one-piece stamping molding, and the other is split welding molding.

[0003] The Chinese utility model patent published on March 6, 2018, with the announcement number CN207071011U, describes a split spoon. By fitting the welding plate and the welding plane, and fitting the cross-section above the welding plate and the spoon edge above the welding plane, the welding positioning between the spoon body and the connecting part can be very conveniently achieved, eliminating the quality problems caused by welding misalignment, such as affecting the appearance and breaking of the weld during use.

[0004] However, during the welding process of the connecting piece and the spoon body of this split spoon, the welding plane of the spoon body and the welding plate of the connecting piece are only fitted on one side before welding, thereby forming only an arc-shaped weld. The welding strength and stability are poor, and there is no compensation material in the welding of the connecting piece and the spoon body and the connecting piece and the spoon handle. After the welding is fixed and cooled, the weld is prone to appear concave, which makes subsequent polishing and grinding more difficult. Moreover, the overall surface will not look smooth and uniform after polishing, which affects the appearance. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the utility model provides a kitchen utensil handle that can avoid the occurrence of weld depressions during welding, so as to solve the problems of the existing welding method having poor welding strength and stability, the weld being easily depressed, the subsequent polishing being difficult, and the overall surface not appearing smooth and uniform after polishing, which affects the appearance.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a kitchen utensil handle capable of preventing weld depressions during welding, the handle comprising:

[0007] a tubular handle portion having a large open end and a small open end;

[0008] The connecting piece has a first welding portion and a second welding portion, the first welding portion is adapted to the size of the small opening end of the tubular handle portion, the second welding portion is connected to the kitchen utensil head, an arc-shaped groove is provided on one side of the top opening of the kitchen utensil head, the curvature of the second welding portion is adapted to the curvature of the arc-shaped groove, a first convex rib is provided on the outer circumference of the first welding portion, and a second convex rib is provided on the outer circumference of the second welding portion. When the second welding portion is in contact with the arc-shaped groove, welding ears are provided at both ends of the second convex rib protruding from the two top ends of the arc-shaped groove.

[0009] Preferably, a plug-in block is provided on the end face of the first welding portion, and at least one third rib is symmetrically provided on both sides of the plug-in block, and the distance between the back-to-back sides of the third ribs symmetrically provided on both sides of the plug-in block is adapted to the distance between the inner walls of the small opening end of the tubular handle portion.

[0010] Preferably, the plug-in block is provided with a first guide portion coinciding with its central axis at one end facing away from the first welding portion, and the third rib is provided with a second guide portion at one end facing away from the first welding portion, and the second guide portions are symmetrically arranged on both sides of the first guide portion, and the distance between the back-to-back faces of the second guide portions symmetrically located on both sides of the first guide portion gradually decreases from near to far from the first welding portion.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0025] like Figure 1 、 Figure 2 and Figure 5 As shown, the utility model provides a kitchen utensil handle which can avoid weld depression during welding. The handle comprises a tubular handle portion 1 and a connecting member 2;

[0026] The tubular handle portion 1 has a large open end and a small open end;

[0027] The connecting member 2 has a first welding portion 211 and a second welding portion 221. The first welding portion 211 is adapted to the size of the small opening end of the tubular handle portion 1. The second welding portion 221 is connected to the kitchen utensil head. An arc-shaped groove is provided on one side of the top opening of the kitchen utensil head. The curvature of the second welding portion 221 is adapted to the curvature of the arc-shaped groove. A first rib 212 is provided on the outer circumference of the first welding portion 211, and a second rib 222 is provided on the outer circumference of the second welding portion 221. When the second welding portion 221 is in contact with the arc-shaped groove, both ends of the second rib 222 protrude from the top of the arc-shaped groove and are provided with welding ears 223.

[0028] Here we take the kitchenware as a soup spoon as an example. Figure 5 As shown, the corresponding kitchen utensil head here is a spoon head, and an arc groove is provided on one side of the top opening of the spoon head:

[0029] Therefore, when the tubular handle portion 1 is welded to the first welding portion 211 of the connecting member 2, and the second welding portion 221 of the connecting member 2 is welded to the kitchen utensil head, after the second welding portion 221 is aligned with the arc-shaped groove of the kitchen utensil head, both the inner wall and the outer wall of the kitchen utensil head can be welded to form two arc-shaped welds, thereby improving the welding strength and welding stability.

[0030] The first convex rib 212 and the second convex rib 222 are located at the welding pool and serve as compensation materials during the welding process, so that the weld seam naturally bulges after cooling, effectively avoiding weld seam depression, reducing the difficulty of subsequent polishing, and providing a smooth transition in the subsequent polishing process, so that the entire weld area can be more easily cut flat during the polishing process, ultimately achieving weld marks that are difficult to detect with the naked eye and achieving a smooth and consistent overall surface.

[0031] By setting the welding ear 223, the two welding seams at the welding starting point and end point (i.e., the two end points of the arc groove) of the second welding part 221 and the arc groove can be compensated, so that after the second welding part 221 of the connector 2 is fitted with the arc groove aligned with the head of the cookware, the welding ear 223 is higher than the opening plane of the top of the head of the cookware, so that the weld is naturally convex after cooling, which can effectively avoid the weld from being concave, reduce the difficulty of subsequent polishing, and make the welding area at this location easier to be cut flat during the polishing process, ultimately achieving welding marks that are difficult to detect with the naked eye, while ensuring the dual improvement of welding strength and aesthetics.

[0032] like Figure 2 As shown, a plug-in block 23 is provided on the end surface of the first welding portion 211, and at least one third rib 24 is symmetrically provided on both sides of the plug-in block 23. The distance between the back-to-back sides of the third ribs 24 symmetrically provided on both sides of the plug-in block 23 is adapted to the distance between the inner walls of the small opening end of the tubular handle portion 1;

[0033] By such a setting, it can be ensured that the plug-in block 23 can be initially clamped and fixed after entering the small opening end of the tubular handle part 1, and the contact area with the inner wall of the tubular handle part 1 can be reduced, making the plug-in smoother, and can reduce the problem of hole-axis sliding interference caused by some deformation of the plug-in block 23 and the small opening end of the tubular handle part 1, which leads to the inability to plug and fix.

[0034] like Figure 2 As shown, the plug block 23 is provided with a first guide portion 231 on the end facing away from the first welding portion 211, which coincides with the central axis thereof. The third rib 24 is provided with a second guide portion 241 on the end facing away from the first welding portion 211. The second guide portions 241 are symmetrically arranged on both sides of the first guide portion 231. The distance between the opposite sides of the second guide portions 241 symmetrically located on both sides of the first guide portion 231 gradually decreases from near to far from the first welding portion 211.

[0035] The first guide portion 231 and the second guide portion 241 are provided to play a guiding role, so that the plug-in block 23 can quickly enter the small opening end of the tubular handle portion 1, thereby achieving rapid alignment and fitting of the two, and facilitating the accuracy of subsequent welding work.

[0036] like Figure 2 As shown, the connecting member 2 includes a straight portion 21 and a bent portion 22. The thickness of the bent portion 22 is adapted to the width of the kitchen utensil head, so that the bent portion 22 forms an integral part with the kitchen utensil head after being welded on the arc groove, making the product more beautiful. The outer surface of the straight portion 21 is a curved surface or an inclined surface. The cross-section of the straight portion 21 gradually increases from near to far from the bent portion 22, making the overall appearance smoother. The first welding portion 211 and the second welding portion 221 are respectively located at the opposite ends of the straight portion 21 and the bent portion 22.

[0037] By providing the bending portion 22, the bending angle can be set according to the casting mold as needed, so that the tubular handle portion 1 is inclined to the top surface of the kitchen utensil head, which is more convenient for people to hold and use.

[0038] like Figure 1 As shown, the tubular handle portion 1 is unfolded into an isosceles trapezoid, and the cross-sectional size of the tubular handle portion 1 gradually decreases from the large opening end to the small opening end, so that the tubular handle portion 1 and the connecting piece 2 at the small opening end are connected more smoothly, and the strength of the tubular handle portion 1 can be ensured, making the overall appearance more beautiful.

[0039] like Figure 3 As shown, the end surface of the first welding portion 211 of the connecting member 2 is provided with a residual material portion 224, and the residual material portion 224 wraps the first welding portion 211;

[0040] After the connector 2 is produced and before it is used, the first welding portion 211 that matches the arc size of the arc groove is obtained by laser cutting the residual material portion 224. Figure 2 The shape of the connector 2 is welded without setting the excess material portion 224 for cutting. After the sandblasting process in the precision casting process, there will be collapsed corners, which is not conducive to the tight fit of the seams. Cutting can ensure the accuracy of the welding line and avoid deformation of the connector 2 during transportation and parts stacking after the connector 2 is precision cast, resulting in inconsistent welding lines.

[0041] like Figure 3 As shown, in order to ensure that the connector 2 has sufficient strength, the straight portion 21 of the connector 2 has a relatively large thickness. Therefore, the connector 2 is not suitable for the manufacturing process of steel plate stamping, and the connector 2 is manufactured by casting.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
