Description

Luggage trolley

This creation department is providing a luggage trolley, which is mainly applied to the production technology of luggage trolleys.

Buttons, suitcases, also known as suitcases and trolleys, are boxes that are carried at the time of exit and are used to place items. It is one of the types of luggage. Usually the suitcase is used to store the clothing, personal care items and souvenirs needed on the trip.

Early luggage was made of wood or other heavy materials. With the popularity of air travel, the material of the luggage tends to be lighter in hard plastic or cloth. Most of the suitcases have a built-in small wheel that can be easily pulled with a lever.

In recent years, there have also been four suitcases with small wheels. In addition to the 360-degree rotation, it can be easily pushed on the ground without any effort.

In addition, the trunk can also be divided into hard-shell luggage and soft-shell luggage according to the outer casing. The hard-shell luggage is more resistant to falling and is suitable for luggage that requires more protection. The soft-shell luggage is usually lighter than the hard-shell luggage and has a more flexible capacity.

Due to the current requirements of strength and durability of the luggage rod, the general luggage rod is made of metal materials such as aluminum and iron. However, the tie rod made of metal material is oxidized on the metal surface. , electroplating, painting, etc., so there are at least the following problems and lacks to be solved.

First, the appearance is monotonous, dull, not beautiful.

Second, the weight is heavier, in vain increase the burden of using physical strength.

Third, the metal is prone to permanent deformation when subjected to impact, and the recovery is poor.

The creator is currently engaged in the manufacture and design of related products, accumulated many years of practical experience and experience, and has actively invested in the spirit of innovation and improvement in the existing problems and lack of the conventional luggage trolley levers.

The technical means applied by the new problem solving and the function of the prior art are: a pull rod is arranged on the back of the luggage box, the pull rod comprises a top seat, a base, a grip and a multi-segment pull rod tube which can be telescopically sleeved; wherein: the pull rod tube It is made of transparent or translucent polymethyl methacrylate (PMMA) or polycarbonate (Polycarbonate, PC) or polyethylene (Ethylene erephthalate, PET). The molded plastic rod tube has the advantages of beautiful appearance, light weight reduction and good deformation recovery after impact, and has an improvement in efficacy, and is the main purpose of achieving it.

In order to make it easier for those who are familiar with the art to understand the content of the device and the functional benefits that can be achieved, a specific embodiment will be listed, and the detailed description will be given as follows: a suitcase lever, respect Please refer to the first and second figures: the schematic diagram of the three-dimensional combination and plane combination of the creation. As shown in the third figure, it is a three-dimensional diagram of the creation of the drawbar tube.

Mainly in:

A pull rod 20 is disposed on the back of the luggage box 10, and the pull rod 20 includes at least two left and right first pull rod tubes 21 and a second pull rod tube 22 that are telescopically sleeved. The first pull rod tube 21 is smaller than the second rod tube 22 The second pull rod tube 22 can be stored in the first pull rod tube 21, and the top end and the bottom end of the left and right sets of the first pull rod tube 21 are respectively fixed to a top seat 23 and a base 24, the left The top two second pull rod tubes 22 are fixed at the top end of the second pull rod tube 25; in use, only the height is required, and the second pull rod tube 22 is pulled up by the grip 25 to the appropriate length, when not in use, The grip 25 is pressed down into the second pull rod tube 22, completely hidden from the first rod tube 21; wherein the first rod tube 21 and the second rod tube 22 are made of transparent or translucent polymethyl methacrylate Polymethyl Methacrylate (PMMA) or Polycarbonate (PC) or Polyethylene (Ethylene Terephthalate, PET) melted and extruded plastic rods.

The present invention, which is a combination of the above-mentioned various devices, provides a luggage trolley, which is used in practical applications: please refer to the fourth figure: a schematic cross-sectional view of the drawing tie rod tube. its Medium: One or both of the first and second rod tubes 22 and the second rod tube 22 are formed with a reinforcing rib 26 and a zigzag strip 27.

The luggage rod provided by the present invention, wherein: the cross section of the first rod tube 21 and the second rod tube 22 may be elliptical (as shown in the fifth figure), circular (as shown in the sixth figure), Polygon, square, trapezoid, and D-shape select one of them.

The trunk pull rod provided by the present invention, wherein: the first pull rod tube 21 and the second pull rod tube 22 can be sprayed with various paint sprayers of different colors.

The luggage rod provided by the present invention, wherein: the first rod tube 21 and the second rod tube 22 can be added to polymethyl methacrylate or polycarbonate or polyethylene terephthalate. Color material, in order to produce a variety of different color rods.

Based on the above, the creation department provides a luggage trolley. After the actual production of the creator and the repeated operation test, it is confirmed that the functional benefits expected by the creation can be achieved, and at the same time, the first thing that has not been seen before. "Creation", with "industry use value", has already met the requirements of the establishment of the "patentability" and "progressiveness" of the new patents, and has filed a new patent application with the bureau in accordance with the provisions of the Patent Law.
