Description

Technical Field

[0001] The utility model relates to the technical field of bags, in particular to a bag with retractable wheels. Background Art

[0002] Luggage itself is a general term for bags used to hold items. Currently, the widespread perception of luggage is for common suitcases. This type of luggage can hold a large number of items and can carry more items when traveling long distances. Due to its large capacity and the large amount of things it can hold, the luggage is heavier after it is filled. In order to facilitate movement, universal wheels and retractable pull rods are usually set on the luggage.

[0003] However, the universal wheels at the bottom of the luggage are usually fixedly installed, and the universal wheels appear obtrusive when there is no need to move the luggage. In addition, when the luggage is placed with the universal wheels as support, it is not stable enough and is easily displaced when it is collided. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model discloses a luggage with retractable wheels, and the technical scheme adopted is that it includes a box body, a handle, a retractable pull rod, a top knob, a mounting bottom plate, a universal wheel, a bottom placement groove, a channel, an internal U-shaped cavity, a lifting structure and a mounting rod, wherein the handle is fixed on the top of the box body, a retractable pull rod is arranged on the rear side, the top knob is rotatably mounted on the top surface of the box body, an anti-slip groove is arranged on the side wall of the top knob, a bottom placement groove is opened at the bottom of the box body, and the bottom placement groove is connected with the internal U-shaped cavity both inside the front and rear parts of the box body through the channel, and the internal U An upgrading structure is set in the cavity and the mounting rod is installed through it. The lower end of the mounting rod extends from the channel into the bottom placement groove and the mounting base plate is fixed at the lower end. A universal wheel is installed under the mounting base plate. The lifting structure is driven by the top knob. The top knob is driven manually to make the lifting structure operate, and finally the lifting and lowering of the mounting rod can be realized. When the mounting rod is lifted, the mounting base plate can be placed in the bottom placement groove so that it contacts the inner top surface of the bottom placement groove. At this time, the universal wheel is placed in the bottom placement groove, and the bottom of the box is supported by its own lower surface, so the placement is relatively stable.

[0005] As a preferred technical solution of the utility model, the wheel body of the universal wheel is covered with a rubber sleeve.

[0006] As a preferred technical solution of the utility model, the lifting structure includes a rotating stud, a guide shaft and a U-shaped frame. A guide shaft and a rotating stud are respectively fixed in two internal U-shaped cavities. The U-shaped frame is placed in the internal U-shaped cavity and is respectively installed in cooperation with the rotating studs and movably fitted with the guide shaft. The rotating stud is driven by a top knob, and the bottom surface of the U-shaped frame is fixedly connected to the mounting rod. When the top knob drives the rotating stud to rotate, the U-shaped frame installed in cooperation with it moves up and down along the guide shaft, thereby driving the mounting rod fixedly connected to it to move up and down.

[0007] As a preferred technical solution of the present utility model, the guide shaft is made of stainless steel.

[0008] As a preferred technical solution of the utility model, scale grooves are evenly distributed on the top surface of the top knob, and a comparison groove is opened on the top surface of the box body 1.

[0009] The beneficial effects of the utility model are as follows: the lifting structure arranged in the box is driven by the top knob, and the operation of the lifting structure can drive the installation rod to move up and down. The up and down movement of the installation rod can make the installation base plate drive the universal wheel to be placed in the bottom placement groove or move out of the bottom placement groove, so that the box can be stably placed on the ground when it does not need to be moved.

DETAILED DESCRIPTION

[0014] Example 1

[0015] like Figures 1 to 3As shown, the utility model discloses a luggage with retractable wheels, and the technical scheme adopted is that it includes a box body 1, a handle 2 and a retractable pull rod 3, which is characterized by: including a top knob 4, a mounting base 5, a universal wheel 6, a bottom placement groove 7, a channel 8, an internal U-shaped cavity 9, a lifting structure and a mounting rod 13. The handle 2 is fixed on the top of the box body 1, and the retractable pull rod 3 is arranged on the rear side. The top knob 4 is rotatably installed on the top surface of the box body 1, and the side wall of the top knob 4 is provided with an anti-slip groove 41. A bottom placement groove 7 is opened at the bottom of the box body 1, and the bottom placement groove 7 is connected with the internal U-shaped cavity 9 provided in the front and rear parts of the box body 1 through the channel 8. An upgrading structure is arranged in the internal U-shaped cavity 9 and the mounting rod 13 is installed through it. The lower end of the mounting rod 13 extends from the channel 8 into the bottom placement groove 7 and the mounting base 5 is fixed at the lower end. The universal wheel 6 is installed under the mounting base 5, and the lifting structure is driven by the top knob 4.

[0016] As a preferred technical solution of the present invention, the wheel body of the universal wheel 6 is covered with a rubber sleeve.

[0017] As a preferred technical solution of the utility model, in order to be able to stably place the box when it is not necessary to move, a lifting structure is set to realize the retraction of the universal wheel 6. Specifically, the lifting structure includes a rotating stud 10, a guide shaft 11 and a U-shaped frame 12. A guide shaft 11 and a rotating stud 10 are respectively fixed in the two internal U-shaped cavities 9. The U-shaped frame 12 is placed in the internal U-shaped cavity 9 and is respectively installed in cooperation with the rotating stud 10 and movably fitted with the guide shaft 11. The rotating stud 10 is driven by the top knob 4, and the bottom surface of the U-shaped frame 12 is fixedly connected to the mounting rod 13.

[0018] As a preferred technical solution of the present utility model, the guide shaft 11 is made of stainless steel.

[0019] As a preferred technical solution of the utility model, scale grooves 42 are evenly distributed on the top surface of the top knob 4, and a reference groove 43 is opened on the top surface of the box body 1. By comparing the scale grooves 42 with the reference grooves 43, the number of rotations of the two top knobs 4 can be accurately controlled so that the universal wheels on the front and rear sides are at the same height.

[0020] The working principle of the utility model is as follows: when the box body 1 does not need to be moved, the two top knobs 4 are manually rotated to drive the rotating studs 10 to rotate so that the U-shaped frame 12 installed therewith is lifted along the guide shaft 11, driving the mounting rod 13 to move upward, thereby driving the mounting base plate 6 to move upward, and the universal wheels 6 arranged on the bottom surface of the mounting base plate 6 are moved upward, and retracted into the bottom placement groove 7 for temporary placement. At this time, the box body 1 can be stably placed on the ground.

[0021] Components not described in detail herein are prior art.

[0022] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the scope of protection of the present invention.
