Technical Field

[0001] The utility model relates to the technical field of backpacks, in particular to a portable multifunctional backpack. Background Art

[0002] Traditional suitcases and backpacks are generally equipped with casters and straps for portability, so that the suitcases can be dragged and carried. Since the casters are in contact with the ground, they are particularly susceptible to dirt. Suitcases and backpacks are sometimes carried with straps. At this time, the outer periphery of the casters after walking on the ground is already contaminated with dirt, especially on rainy days, when the dirt is more serious. The dirty wheels are bound to easily stain the user's body or the back of clothes, resulting in a certain degree of dirtiness in the carrying method, which often makes the user very uncomfortable and embarrassed. There is a need for improvement. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0028] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without the specific details or the specific manner described herein.

[0029] See also Figure 1-5 The utility model provides a portable multifunctional backpack, comprising: a luggage backpack 1, a shoulder strap 2, a mounting groove 3, a moving wheel 4, a blocking cover 5, and a rubber block 6. The shoulder strap 2 is connected to one side of the luggage backpack 1; the mounting groove 3 is opened on the lower side of the luggage backpack 1; the moving wheel 4 is arranged on the mounting groove 3; the blocking cover 5 is rotatably connected in the mounting groove 3 through a rotating rod 7 and is located above the moving wheel 4; the rubber block 6 is installed on both sides of the blocking cover 5 and fits with the groove wall of the mounting groove 3.

[0030] When in use, the blocking cover 5 is connected to the mounting groove 3 through the rotating rod 7. When the user carries the backpack, by turning the blocking cover 5 downward, the blocking cover 5 can be turned out of the mounting groove 3 with the rotating rod 7 as the axis under the action of the rotating rod 7. The blocking cover 5 is turned downward until it covers the part of the moving wheel 4 that leaks out of the mounting groove 3, so that when carrying the backpack, the user's back will not contact the moving wheel 4 contaminated with dirt but will contact the blocking cover 5 through the blocking of the blocking cover 5, so that the backpack will not be troubled by dirt. Among them, when the blocking cover 5 is in the mounting groove 3, the blocking cover 5 squeezes the rubber block 6 to fit with the mounting groove 3, and the blocking cover 5 is relatively stable in the mounting groove 3, so that it will not automatically rotate out without external force, which will be more practical.

[0031] According to some embodiments of the present application, optionally, a threaded rod 8 is connected to the shield 5, and a threaded hole for the threaded rod 8 to be screwed in is provided in the mounting groove 3. Since the backpack shakes violently when the user drags it on a bumpy road, the shield 5 may automatically rotate out of the mounting groove 3 if the rubber block 6 is tightened, which affects the normal rotation of the moving wheel 4. That is, the threaded rod 8 passes through the shield 5 and is locked on the threaded hole, so that the shield 5 is fixed in the mounting groove 3, thereby increasing the stability of the connection between the shield 5 and the mounting groove 3.

[0032] According to some embodiments of the present application, optionally, a cushion 9 is connected to one side of the shield 5. In order to prevent the shield 5 from contacting the user's back and causing discomfort thereto, the cushion 9 plays a role of shock isolation and wear prevention, thereby making the carrying more comfortable.

[0033] According to some embodiments of the present application, the guard 5 is optionally divided into a wheel guard 51 and a drip guard 52, and the wheel guard 51 is vertically connected to the drip guard 52. When rotating downward, the wheel guard 51 is on the side of the moving wheel 4, and the drip guard 52 blocks the bottom of the moving wheel 4. Under the action of the drip guard 52, the water stains dripped by the moving wheel 4 (when it rains, the moving wheel 4 will be stuck with a certain amount of mud or sewage when it contacts the muddy road surface, and these water stains will drip down along the moving wheel 4 when it is carried. Only by blocking the side with the wheel guard 51, it will not be possible to prevent the water stains from dripping on the back of the user's trouser legs or the back of the shoe) will flow along the direction of the drip guard 52 until discharged, which extends the direction of the water stains flowing out after dripping, effectively preventing the water stains from dripping on the back of the user's trouser legs or the back of the shoe, and reducing the trouble of dirt.

[0034] According to some embodiments of the present application, the threaded rod 8 is optionally connected to the wheel guard 51 , which has the function of locking the wheel guard 51 in the mounting groove 3 .

[0035] According to some embodiments of the present application, optionally, a retractable pull rod 10 is provided on the luggage backpack 1, which facilitates the dragging of the backpack.

[0036] According to some embodiments of the present application, optionally, a hand strap 11 is installed on the luggage backpack 1, which has the function of facilitating the carrying of the backpack.

[0037] According to some embodiments of the present application, a sponge filling bag 12 is optionally provided on the luggage backpack 1 on the same side as the shoulder strap 2. Since the back of the luggage backpack 1 is relatively hard, the sponge filling bag 12 provides a buffering barrier, which makes the backpack more comfortable to carry and less likely to hurt the user's back.
