Universal wheels are movably connected to the lower part of each universal wheel base, and a handle is fixedly connected to the middle of the left side of the suitcase.

[0004] Current rolling suitcases, as described above, are generally rectangular in shape, which results in a small supporting area. If the wide side of the suitcase is subjected to external force, the suitcase will inevitably tip over. If it is filled with fragile items, it may be damaged. There is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a trolley case with an adjustable handle structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trolley case with an adjustable handle structure, comprising a case body and a fixing plate. The fixing plate is detachably installed on the outer wall of one side of the case body by bolts. A support assembly is installed on the outside of the fixing plate, and a lifting assembly is installed inside the fixing plate. The support assembly includes a hinge fixedly connected to the outer wall of one side of the fixing plate. A horizontally arranged support frame is rotatably connected inside the hinge. The support frame can contact the top of the ground. A gear is rotatably connected to the outer walls of both ends of the hinge. The two gears are respectively coaxially fixed to the two ends of the rotating shaft of the support frame.

[0007] As a further preferred embodiment of this technical solution, a limiting groove is provided on both sides of the outer wall of one side of the fixing plate. Both limiting grooves are vertically arranged, and a connecting strip is slidably inserted into the inside of each limiting groove. A toothed rack is fixedly connected to the bottom of each connecting strip.

[0008] The pull rod can be pulled to the top to drive the support frame to contact the ground, thus greatly increasing the support area of ​​the box and effectively preventing the box from tipping over when subjected to external forces. As the handle moves, the two connecting bars are also driven to move synchronously. Then, the rack at its end will contact and mesh with the gear, which will drive the support frame to flip outward until the roller at its end contacts the ground and stops. At this time, the two locking heads will also enter the two ports of the top positioning slot. Conversely, the support frame can be flipped inward by pushing the pull rod back, so as not to occupy too much space and to facilitate use.

[0009] As a further preferred embodiment of this technical solution, the lifting assembly includes two pull rod bodies that are slidably inserted into the top outer wall of the fixed plate. The top one end of the two pull rod bodies is fixedly connected to the same handle body. Both connecting strips are fixedly connected to the handle body. A button is slidably inserted into the top of the handle body. The top inner wall of the button is fixedly connected to the same spring with the bottom inner wall of the handle body. A push-pull strip is hinged to both sides of the bottom of the button.

[0010] As a further preferred embodiment of this technical solution, the inner walls on both sides of the handle body are fixedly connected with the same horizontally arranged limiting rod. Two positioning rods are slidably sleeved on the outside of the limiting rods. Both positioning rods are in contact with the bottom inner wall of the handle body. The two push-pull strips are respectively hinged to the two positioning rods at their respective close ends. A locking head is fixedly connected to the inner wall of the two positioning rods on their respective close sides.

[0011] As a further preferred embodiment of this technical solution, the fixing plate has two horizontally arranged positioning grooves inside, and the two clips can be slidably inserted into the through holes at both ends of the two positioning grooves.

[0012] Pulling the handle body upwards via the lever body causes it to slide upwards along the fixed plate, which in turn moves the internal locking head synchronously. When it aligns with one of the positioning slot ports at the bottom, the compressed spring returns to its length, causing the button and one end of the two push-pull bars to move synchronously. The positioning rods, which are sleeved outside the limit rod, are brought closer together by the two push-pull bars, and the locking heads at the bottom of the two positioning rods are inserted into the two ports of the bottom positioning slot respectively. To unfold the support frame, press the button again to disengage the two positioning rods and locking heads from the positioning slots, and then continue pulling the handle body. The handle position can be adjusted as needed, making it more adaptable.

[0013] As a further preferred embodiment of this technical solution, a magnetic block is fixedly connected to both sides of the top outer wall of the support frame, and an iron sheet adapted to the two magnetic blocks is provided inside the box.

[0014] As a further preferred embodiment of this technical solution, the bottom outer wall of the support frame is provided with two rollers, and the two rollers are at the same level.

[0015] This utility model provides a trolley case with an adjustable handle structure, which has the following advantages:

[0016] (1) By setting up a support component, this utility model can drive the support frame to contact the ground after the pull rod body is pulled to the top, thereby greatly increasing the support area of ​​the box and effectively preventing the box from tipping over when subjected to external force. When the handle body moves, the two connecting strips will also be driven to move synchronously. Then the rack at its end will contact and mesh with the gear, and the gear can drive the support frame to flip outward until the roller at its end contacts the ground and stops. At this time, the two clips will also enter the two ports of the top positioning groove. Conversely, the support frame can also be controlled to flip inward by pushing the pull rod body back, so as not to occupy too much space and to facilitate use.

[0017] (2) By setting up a lifting component, the handle body is pulled upward by the pull rod body, and it will slide upward along the fixed plate. The internal locking head will also be driven to move synchronously. When it is opposite to a positioning groove port at the bottom, the compressed spring will return to its length, which will drive the button and one end of the two push-pull bars to move synchronously. The positioning rod sleeved outside the limiting rod will be driven to move closer to each other by the two push-pull bars. Then the locking heads at the bottom of the two positioning rods will be inserted into the two ports of the bottom positioning groove respectively. If the support frame needs to be unfolded, the button can be pressed again to make the two positioning rods and locking heads disengage from the positioning groove. Then the handle body can be pulled again. The position of the handle can be adjusted as needed, making it more adaptable. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides the following technical solution:

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the lifting assembly 6 includes two pull rod bodies 601 that are slidably inserted into the top outer wall of the fixing plate 2. The top end of the two pull rod bodies 601 is fixedly connected to the same handle body 602. Both connecting strips 502 are fixedly connected to the handle body 602. A button 603 is slidably inserted into the top of the handle body 602. The top inner wall of the button 603 and the bottom inner wall of the handle body 602 are fixedly connected to the same spring 607. A push-pull strip 606 is hinged to both sides of the bottom of the button 603.

[0026] The handle body 602 has two horizontally set limit rods 604 fixedly connected to the inner walls on both sides. Two positioning rods 605 are slidably sleeved on the outside of the limit rods 604. Both positioning rods 605 are in contact with the bottom inner wall of the handle body 602. Two push-pull strips 606 are respectively hinged to the two positioning rods 605 at their respective close ends. A clip 609 is fixedly connected to the inner wall of the two positioning rods 605 at their respective close ends.

[0027] The fixing plate 2 has two horizontally arranged positioning grooves 608 inside, and two clips 609 can be slidably inserted into the through holes at both ends of the two positioning grooves 608 respectively.

[0028] Pulling the handle body 602 upward by pulling the lever body 601 causes it to slide upward along the fixed plate 2, which in turn causes the locking head 609 inside to move synchronously. When it aligns with the port of the bottom positioning groove 608, the compressed spring 607 will return to its length, causing the button 603 and one end of the two push-pull bars 606 to move synchronously. The positioning rod 605, which is sleeved outside the limit rod 604, will be moved closer to each other by the two push-pull bars 606, and the locking heads 609 at the bottom of the two positioning rods 605 will be inserted into the two ports of the bottom positioning groove 608 respectively. If the support frame 506 needs to be unfolded, the button 603 can be pressed again to disengage the two positioning rods 605 and the locking heads 609 from the positioning groove 608. Then the handle body 602 can be pulled again. The position of the handle can be adjusted as needed, making it more adaptable.

[0029] like Figure 1 and Figure 2 As shown in this embodiment, a trolley case with an adjustable handle structure includes a case body 1 and a fixing plate 2. The fixing plate 2 is detachably installed on the outer wall of one side of the case body 1 by bolts. A support assembly 5 is installed on the outside of the fixing plate 2, and a lifting assembly 6 is installed inside the fixing plate 2. The support assembly 5 includes a hinge seat 504 fixedly connected to the outer wall of one side of the fixing plate 2. A horizontally arranged support frame 506 is rotatably connected inside the hinge seat 504. The support frame 506 can contact the top of the ground. A gear 505 is rotatably connected to the outer walls of both ends of the hinge seat 504. The two gears 505 are coaxially fixed to the two ends of the rotating shaft of the support frame 506, respectively.

[0030] A limiting groove 501 is provided on both sides of the outer wall of one side of the fixed plate 2. Both limiting grooves 501 are vertically arranged. A connecting strip 502 is slidably inserted into the two limiting grooves 501. A rack 503 is fixedly connected to the bottom of the two connecting strips 502.

[0031] As the handle body 602 moves, the two connecting bars 502 are also driven to move synchronously. Then, the rack 503 at its end will contact and mesh with the gear 505, which will drive the support frame 506 to flip outward until the roller 3 at its end contacts the ground and stops. At this time, the two clips 609 will also enter the two ports of the top positioning groove 608. Conversely, the support frame 506 can also be controlled to flip inward by pushing back the pull rod body 601, so as not to occupy too much space and to facilitate use.

[0032] like Figure 1 As shown in Figure 2, a magnetic block 4 is fixedly connected to both sides of the top outer wall of the support frame 506. The box 1 is equipped with an iron sheet that matches the two magnetic blocks 4. When the support frame 506 is flipped up, the magnetic block 4 at the top will be attracted to the outside of the iron sheet on the outer wall of the box 1, thus avoiding the inconvenience caused by the support frame 506 being unfolded again.

[0033] like Figure 1 As shown in Figure 2, the bottom outer wall of the support frame 506 is provided with two rollers 3. The two rollers 3 are at the same level, so that the sliding friction between the support frame 506 and the ground is transformed into rolling friction, which facilitates the movement of the box 1.

[0034] This utility model provides a trolley case with an adjustable handle structure, and its working principle is as follows:

[0035] When the device is in operation, pulling the handle body 602 upward via the pull rod body 601 causes it to slide upward along the fixed plate 2. This causes the locking head 609 inside to move synchronously. When it aligns with one of the positioning slots 608 at the bottom, the compressed spring 607 returns to its original length, causing the button 603 and one end of the two push-pull bars 606 to move synchronously. The positioning rods 605, which are sleeved outside the limiting rod 604, are pulled closer together by the two push-pull bars 606. The locking heads 609 at the bottom of the two positioning rods 605 then insert into the two ports of the bottom positioning slot 608. To unfold the support frame 506, press the button 603 again to disengage the two positioning rods 605 and the locking heads 609 from the positioning slots 608. Then, the device can continue... Continue pulling the handle body 602; the handle position can be adjusted as needed, making it more adaptable. As the handle body 602 moves, the two connecting bars 502 are also driven to move synchronously. Subsequently, the rack 503 at its end will contact and mesh with the gear 505, which will drive the support frame 506 to flip outward until the roller 3 at its end contacts the ground and stops. At this time, the two clips 609 will also enter the two ports of the top positioning groove 608. Conversely, the support frame 506 can also be flipped inward by pushing back the pull rod body 601, so as not to occupy too much space and to facilitate use. The magnetic block 4 on the top of the support frame 506 will also be attracted to the outside of the iron plate set on the outer wall of the box 1, avoiding the inconvenience caused by the support frame 506 re-expanding.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
