Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to a high-strength spatula. Background Technology

[0002] In the kitchenware manufacturing industry, the spatula, as a basic and frequently used cooking tool, directly impacts user experience and product lifespan due to its structural reliability and durability. Currently, conventional spatulas on the market have significant structural design flaws, especially at the connection between the spatula and the handle.

[0003] First, the tip of a conventional shovel's handle is typically a simple bevel, while the shovel itself has an arc-shaped structure. This structural mismatch results in a noticeable gap when the handle and shovel are connected, preventing a tight fit. This incomplete contact surface leads to uneven stress distribution at the connection point, which can easily cause stress concentration during prolonged stir-frying under stress. This significantly reduces the overall strength of the connection structure, posing a risk of breakage.

[0004] Secondly, from the perspective of connection technology, most spatulas on the market currently use only a few spot welds to fix the connection between the handle and the spatula. Although this connection method is simple to manufacture and low in cost, the actual effective welding area is too small, failing to form continuous and uniform stress support throughout the connection area. When the spatula is subjected to large torsional forces or repeated stress, these limited weld points are very likely to become structural weak points, potentially leading to weld cracking or loosening of the connection, further affecting the overall structural strength and safety of the product. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a high-strength spatula.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-strength spatula includes a spatula portion and a rod portion fixedly disposed at one end of the spatula portion; the rod portion includes a connecting surface that contacts the spatula portion, the connecting surface being an arc surface adapted to the spatula portion to improve the connection strength between the rod portion and the spatula portion.

[0007] In the above scheme, preferably, the shovel protrusion is provided with a connecting part, and the back of the connecting part is used for fixed connection with the rod.

[0008] In the above scheme, it is preferred that the rod part is a hollow rod.

[0009] In the above scheme, preferably, the rod is provided with a positioning step for positioning.

[0010] In the above scheme, preferably, the positioning step includes a positioning surface, which extends from the end of the connecting surface.

[0011] In the above scheme, preferably, the width of the positioning surface is adapted to the thickness of the shovel.

[0012] In the above scheme, preferably, the width of the positioning surface is less than or equal to the thickness of the shovel.

[0013] In the above scheme, preferably, the connecting surface of the rod is matched with the back of the spatula, and the positioning surface is matched with the side of the spatula.

[0014] In the above scheme, it is preferred that the connecting part of the rod and the shovel part are welded together.

[0015] In the above scheme, preferably, the connecting surface of the shovel and the outer edge of the rod are fixed by laser welding.

[0016] The beneficial effects of this invention are as follows: By designing the connecting surface at the front end of the rod to match the arc surface on the back of the shovel, the rod and shovel can fit tightly together, achieving a seamless connection. The tight fit of the full contact surfaces allows the force to be evenly distributed throughout the connection area, effectively avoiding stress concentration and enhancing the structural strength and torsional and bending resistance of the connection. The use of full-circle laser welding creates a continuous weld seam at the outer edge of the connection between the rod and shovel, greatly extending the product's service life.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: Example 1: See Figures 1-2 A high-strength spatula includes a spatula part 1 and a handle part 2. The spatula part 1 is typically made of a high-strength material, such as stainless steel or aluminum alloy, to ensure durability and high-temperature resistance. The handle part 2 is fixedly mounted at one end of the spatula part 1 for the user to hold and operate.

[0022] The spatula 1 has a common spatula-shaped structure, and its edges can be designed with thin blades to facilitate stir-frying food. The rod 2 is fixed to one end of the spatula 1. Specifically, the rod 2 includes a connecting surface 3 that contacts the spatula 1. The connecting surface 3 is an arc-shaped surface adapted to the spatula 1, allowing the rod 2 to fit tightly against the spatula 1 without gaps. This arc-shaped surface design helps with stress distribution, improves connection strength, and prevents loosening or breakage during use.

[0023] Furthermore, a connecting portion 4 is provided on the back of the shovel portion 1, and the back of the connecting portion 4 is used for fixed connection with the rod portion 2. The connecting portion 4 is integrally formed with the shovel portion 1, for example, by stamping or casting processes, to ensure structural integrity.

[0024] The rod 2 is a hollow rod, made of lightweight materials such as aluminum alloy or titanium alloy, to reduce overall weight while maintaining sufficient strength. The hollow rod structure also reduces material costs.

[0025] Example 2: Further improvements are made to rod 2 based on Example 1. See [link / reference] Figures 3-4 .

[0026] The rod 2 is provided with a positioning step for positioning. The positioning step includes a positioning surface 5, which extends from the end of the connecting surface 3. The width of the positioning surface 5 is adapted to the thickness of the shovel 1; specifically, the width of the positioning surface 5 is less than or equal to the thickness of the shovel 1. Thus, when the rod 2 is connected to the shovel 1, the positioning surface 5 can fit tightly against the side of the shovel 1, achieving precise alignment and ensuring connection stability.

[0027] The connecting surface 3 of the rod 2 is matched to the back of the spatula, meaning the curvature of the connecting surface 3 is the same as the curvature of the back of the spatula 1 or the connecting part 4 of the spatula 1. The positioning surface 5 is matched to the side of the spatula, meaning the positioning surface 5 is parallel to the side of the spatula 1. Simultaneously, an angle is formed between the positioning surface 5 and the connecting surface 3, which can be engaged with the spatula 1, allowing the rod 2 and the spatula 1 to form a three-dimensional fit during connection, enabling rapid positioning and further eliminating gaps.

[0028] The rod 2 and the shovel 1 are connected by welding, specifically laser welding. During welding, the connecting surface 3 of the rod 2 is first aligned with the back of the connecting part 4 of the shovel 1, and pre-positioned using a positioning step. Then, laser welding is performed around the entire circumference along the connecting surface 3, positioning surface 5, and outer edge of the rod 2. Laser welding achieves deep penetration welding, resulting in narrow and deep welds with a small heat-affected zone, thus ensuring high connection strength and a neat appearance.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
