Description

Technical Field

[0001] The utility model relates to the technical field of trolley cases, in particular to a trolley case dedicated to musical instruments. Background Art

[0002] A trolley case refers to a suitcase with a drawbar and rollers, which is widely used because of its convenience. At the same time, a trolley case is also divided into a single-tube drawbar and a double-tube drawbar because the case has a drawbar. The drawbar tube is also divided into a square tube and a round tube, so that it is convenient to drag when walking and greatly reduce the burden. The trolley case is mainly made of cloth boxes, ABS hard boxes, leather boxes and PC, etc. However, there are certain disadvantages when using the devices in the prior art. For example, the publication number: CN220631329U records a trolley case with good scratch-resistant and wear-resistant protective effect, comprising a first box body, one side of the outer surface of the first box body is rotatably connected to the second box body, the outer surfaces of the first box body and the second box body are fixedly connected to the anti-scratch assembly, the four corners of the first box body and the second box body are fixedly connected to rubber pads, the four corners of the outer surface of the other side of the first box body are fixedly connected to conical blocks, the interior of the first box body is provided with a partition, and the interior of the second box body is fixedly connected to a connecting belt;

[0003] Although the above device can improve the toughness of the outer surface of the box by setting a wear-resistant layer, for a guzheng player, the player usually puts the guzheng in a storage bag, carries the storage bag on the back, and then pulls a suitcase with performance clothes, rosin and other items in the suitcase. Since the length of the guzheng is greater than the length of the suitcase, the guzheng cannot be stored in the suitcase, making it inconvenient for the player to move the guzheng through the suitcase.

The Guzheng storage bag can be stored through the PE half box and the PE frame. There are four fixed seats, which are installed inside the PE half box. In the initial state, the torsion spring makes the end of the clamping frame close to the inner wall of the PE half box. After the Guzheng storage bag is inserted into the PE half box, manually tie multiple ties together to make the clamping frame overcome the elastic force of the torsion spring, so that the clamping frame can clamp the Guzheng storage bag, thereby avoiding the lower end of the Guzheng storage bag from swinging in the PE half box during transportation, which is convenient for the transportation of the Guzheng.

[0015] 2. Manually rotate the locking knob through the set fixing sleeve so that the locking knob is separated from the limit cylinder under the push of the thread, and then manually pull the folding silicone sleeve outward, rotate the locking knob in the opposite direction so that the outer surface of the locking knob contacts the fixing sleeve, and then the folding silicone sleeve can be fixed, thereby increasing the volume of the box. When the Guzheng is not being carried, manually insert the card plate back so that the box can be used as a suitcase. BRIEF DESCRIPTION OF THE DRAWINGS

After opening the PE frame 3, the snap-in plate 101 is pulled outward, and the guzheng storage bag 9 can be inserted into the PE half box 1. The guzheng storage bag 9 can be stored by cooperating with the PE half box 1 and the PE frame 3. When it is necessary to increase the storage space, the folding silicone sleeve 301 can be unfolded in conjunction with the limiting cylinder 401 and the guide rod 404 to increase the volume of the box, which is convenient for guzheng players to use. The user can pull the suitcase with the pull rod 6 or the handle 601 and the universal self-locking wheel 8.

[0024] Embodiment 1

[0025] like Figure 1-2As shown, the outer surface of the PE half box 1 is nested and fixedly connected with a No. 1 reinforcement frame 2 near the side surface, the inner surface of the foldable silicone sleeve 301 is sewn with a zipper 305, the outer surface of the zipper 305 is sewn with an isolation cloth 303, the side surface of the isolation cloth 303 is sewn with a storage bag 304, the outer surface of the limiting cylinder 401 is provided with a limiting groove 402, the outer surface of the guide rod 404 is threadedly connected with a locking knob 403, and the guide rod 404 is inserted into the limiting cylinder 401.
