Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, and in particular to a trolley case handle with an L-shaped reinforcing strip. Background Technology

[0002] A rolling suitcase is a type of luggage equipped with a pull handle and wheels. It is widely used due to its convenience. Rolling suitcases are further categorized by the pull handle: single-tube and double-tube handles are available. The handle itself can also be square or round, designed to facilitate dragging while walking and significantly reduce the burden on the rider.

[0003] A typical rolling suitcase usually consists of two telescopic rods, a sleeve for storing the rods inside the suitcase, and a handle between the two rods. The handle has a button for controlling the extension and positioning of the rods. The handle is often designed in a straight line to fit snugly into the suitcase when folded up, avoiding protrusion. In addition, the handle is usually made of plastic, which has low rigidity. When customers pull the suitcase, they rely on the handle to control the pulling and turning, which generates a large torque on the handle. The plastic handle is prone to bending and deformation, which can affect the accuracy of the button unlocking the telescopic rod. It can also affect the grip comfort and stable storage of the handle. Summary of the Invention

[0004] The purpose of this utility model is to provide a trolley handle with an L-shaped reinforcing strip, which can improve the overall rigidity of the handle, ensure the stable operation of the internal parts of the handle, maintain grip comfort and stable storage.

[0005] To achieve the above objectives, a trolley handle with an L-shaped reinforcing strip is provided, comprising: an upper cover; a lower cover with rod sleeves extending from the bottom of its left and right ends; an upper cover being snapped into place on the front top of the lower cover; an L-shaped reinforcing strip between the lower cover and the upper cover; the bottom side of the L-shaped reinforcing strip being embedded downward into the inner rear part of the lower cover; the top side of the L-shaped reinforcing strip being fitted upward into the upper cover; and a button being slidably fitted into the top center of the upper cover. A combined handle with the embedded L-shaped reinforcing strip enhances the overall rigidity of the handle. The long strip design provides a straight-line limit and shape for the handle, preventing bending, while the L-shaped bend design ensures a stable fit with the handle, effectively preventing twisting deformation and ensuring stable operation of the internal parts, maintaining grip comfort and stable storage.

[0006] According to the aforementioned trolley handle with an L-shaped reinforcing strip, the L-shaped reinforcing strip is made of a high-hardness metal material. High-hardness materials such as aluminum alloy or 201 stainless steel are used to ensure the overall strength of the handle after it is filled.

[0007] According to the aforementioned trolley handle with an L-shaped reinforcing strip, a pre-drilled slot is provided on the top front side of the L-shaped reinforcing strip, and the inner edge of the pre-drilled slot corresponds to the sliding engagement of the button. This avoids affecting the normal unlocking path of the telescopic rod and completes the normal unlocking and pulling out.

[0008] According to the aforementioned trolley handle with an L-shaped reinforcing strip, the lower cover has several mounting holes equidistantly spaced on its lower side. These mounting holes are fitted with concealed screws to securely fasten the upper and lower covers together. This ensures a stable connection between the upper and lower covers while maintaining a clean and simple overall appearance for the handle.

[0009] According to the aforementioned trolley handle with an L-shaped reinforcing strip, the outer corners of both the upper and lower covers are rounded to eliminate sharp edges and prevent scratches to the hands.

[0010] According to the aforementioned trolley handle with an L-shaped reinforcing strip, the outer surfaces of both the upper and lower covers are polished to prevent chafing.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] In this utility model, a combined handle is used in conjunction with an embedded L-shaped reinforcing strip to improve the overall rigidity of the handle. The long strip design limits and shapes the handle in a straight line to prevent bending, while the L-shaped bend design allows it to fit stably with the handle to effectively prevent torsional deformation, thereby ensuring the stable operation of the internal parts of the handle, maintaining grip comfort and stable storage.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-3 This utility model embodiment provides a trolley handle with an L-shaped reinforcing strip, including: a lower cover 1, with rod sleeves 2 extending from the bottom of the left and right ends of the lower cover 1, an upper cover 3 being snapped and fixed to the top front side of the lower cover 1, and a plurality of mounting holes 7 being equidistantly opened on the lower side of the lower cover 1. The mounting holes 7 are correspondingly fitted with concealed screws to tightly fix the upper cover 3 and the lower cover 1, forming a modular design that facilitates the adjustment and replacement of the internal parts of the handle.

[0022] An L-shaped reinforcing strip 4 is provided between the upper cover 3 and the lower cover 1. The L-shaped reinforcing strip 4 is made of high-hardness metal material. The bottom side of the L-shaped reinforcing strip 4 is embedded downward into the inner middle and rear part of the lower cover 1, and the top side of the L-shaped reinforcing strip 4 is fitted upward with the upper cover 3. A button 6 is fitted and slidably mounted at the top center of the upper cover 3. A reserved slot 5 is opened on the top front side of the L-shaped reinforcing strip 4. The inner edge of the reserved slot 5 is fitted and slidably with the button 6 to improve the overall rigidity of the handle. Its long strip design limits and shapes the handle in a straight line to avoid bending problems, while its L-shaped bend design can stably fit with the handle to effectively avoid the torsional deformation of the handle.

[0023] The outer corners of both the upper cover 3 and the lower cover 1 are rounded, and the outer surfaces of both the upper cover 3 and the lower cover 1 are polished. This improves the overall grip comfort of the handle.
