DETAILED DESCRIPTION

[0027] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1 As shown, the outer side walls of the two clamping sleeves 2 located below the two vertical tubes 1 at the rear are both rotatably connected to the moving wheels 12 through the rotating shaft, and the outer side walls of the two horizontal tubes 4 located at the rear are both symmetrically fixedly connected to the fixing sleeves 32, multiple fixing sleeves 32, and the outer side walls of the multiple fixing sleeves 32 are commonly provided with a pull rod mechanism 33;

[0030] When in use, the appropriate pull rod length can be adjusted according to the user's height and actual usage scenario through the adjustment function of the pull rod mechanism 33. Then, by holding the handle part of the pull rod mechanism 33, the trolley case can be pulled forward. At the same time, the two moving wheels 12 rely on their own good rolling performance and carrying capacity to support the weight of the case and the items inside, and roll smoothly on the ground, reducing the impact of bumps on the items in the case.

[0031] like Figure 1 As shown, the interiors of the plurality of ferrules 47 located at the top are all plugged and connected with extension tubes 13, and the interiors of the two ferrules 47 located below the two vertical tubes 1 in the front are all plugged and connected with support legs 14;

[0032] When the suitcase is in a stationary position, the two supporting legs 14 can provide additional stable support for the suitcase, which can share the weight of the suitcase, prevent the suitcase from tipping over due to uneven ground, ensure the stability of the suitcase, and protect the items in the suitcase from shaking, collision, etc.

[0033] like Figure 1-Figure 4 As shown, an exoskeleton structure package with a desktop pull rod is provided, including a vertical tube 1, the number of which is four and is rectangular in shape, the top and bottom ends of the plurality of vertical tubes 1 are plugged and connected with a clamping sleeve 2, the upper and lower ends of two adjacent vertical tubes 1 are each provided with a horizontal tube 3, the upper and lower ends of two distant vertical tubes 1 are each provided with a horizontal tube 4, the front and rear ends of the plurality of horizontal tubes 3 are plugged and connected with a clamping sleeve 5, the plurality of clamping sleeves 5 are respectively fixedly connected to the outer side walls of the plurality of clamping sleeves 2, the left and right ends of the plurality of horizontal tubes 4 are plugged and connected with a clamping sleeve 6, and the plurality of clamping sleeves 6 are respectively fixedly connected to the outer side walls of the plurality of clamping sleeves 2. The outer walls are respectively fixedly connected with the outer walls of the plurality of ferrules 1 2, and the ends of the plurality of ferrules 1 2 and away from the plurality of vertical tubes 1 are fixedly connected with ferrules 4 7, and the insides of the ferrules 1 2, ferrules 2 5, ferrules 3 6 and ferrules 4 7 are fixedly connected with spring pieces 8, and the outer walls of the plurality of spring pieces 8 are fixedly connected with protrusions 9, and the outer walls of the vertical tube 1, the horizontal tube 1 3 and the horizontal tube 2 4 are symmetrically provided with circular holes 10, and the insides of the ferrules 1 2, the ferrules 2 5, the ferrules 3 6 and the ferrules 4 7 are provided with penetrating circular holes 2 11, and the plurality of protrusions 9 respectively pass through the plurality of circular holes 10 and the plurality of circular holes 2 11;

[0034] Through the integration of the ferrule 1 2, the ferrule 2 5, the ferrule 3 6 and the ferrule 4 7 into an integral clamping piece, the multiple transverse tubes 1 3 and the multiple transverse tubes 2 4 are sequentially inserted into the inside of the ferrule 2 5 and the ferrule 3 6 on the outside of the multiple clamping pieces, thereby squeezing the spring pieces 8 and the protrusions 9 in the ferrule 2 5 and the ferrule 3 6 to make them shrink inward, until the multiple transverse tubes 1 3 and the multiple transverse tubes 2 4 are fully inserted into the multiple transverse tubes 2 5 and the appropriate positions in the ferrule 3 6, and the multiple protrusions 9 pop out and pass through the corresponding circular holes 10 and the circular holes 2 11, so that the multiple transverse tubes 1 3 and the multiple transverse tubes 2 4 can be formed into two rectangular frames, and then the two ends of the four vertical tubes 1 are respectively inserted into the interior of the multiple ferrules 1 2, and the preliminary completion can be completed. After the trolley case is formed into the shape of the trolley case, the supporting legs 14 and the moving wheels 12 can be assembled. When the trolley case is used up, the multiple spring pieces 8 can be deformed by pressing the multiple protrusions 9, and the protrusions 9 can be retracted into the inside of the clamping sleeve, so as to complete the rapid disassembly of the various components, which provides great convenience for the storage of the trolley case. At the same time, the support of the multiple transverse tubes 1 3, multiple transverse tubes 2 4 and four vertical tubes 1 can provide the bearing capacity of the trolley case, thereby improving the practicality of the trolley case, and the multiple transverse tubes 1 3, multiple transverse tubes 2 4 and four vertical tubes 1 can be replaced in various ways when in use. Various materials such as aluminum tubes and carbon fiber tubes can be quickly replaced according to different application scenarios, thereby improving the diversity of the trolley case.

[0035] like Figure 1 , Figure 6 and Figure 7 As shown, the outer side wall of the horizontal tube 13 and the front of the two moving wheels 12 are rotatably connected with a rotating block 15, the upper surfaces of the two rotating blocks 15 are fixedly connected with a connecting plate 16, the upper surfaces of the two connecting plates 16 are commonly fixedly connected with a folding plate 17, the rear surface of the folding plate 17 is disassembled and connected with a table board 18 by bolts, and the upper sides of the outer side walls of the two vertical tubes 1 located in the front are fixedly connected with a fixing column 19, the interiors of the two fixing columns 19 are provided with a clamping cavity 20, the interiors of the two clamping cavities 20 are slidably connected with a sliding plate 21, the opposite sides of the two sliding plates 21 are fixedly connected with an oblique block 22, the left and right sides of the folding plate 17 are provided with a positioning groove 23, the opposite sides of the two oblique blocks 22 extend to the interiors of the two oblique blocks 22 respectively, and the opposite sides of the two sliding plates 21 are fixedly connected with a plurality of springs 24 on the opposite sides of the two clamping cavities 20;

[0036] When the folding plate 17 is rotated to a position close to the vertical angle, the position of the folding plate 17 is further adjusted so that the positioning grooves 23 on both sides are aligned with the directions of the two fixing posts 19, and then the folding plate 17 is slightly pressed inward. At this time, the folding plate 17 will squeeze the inclined surface parts of the two oblique blocks 22. Since the two oblique blocks 22 are fixed on the sliding plate 21 and the sliding plate 21 can slide in the engaging cavity 20, under the squeezing of the folding plate 17, the two oblique blocks 22 will be subjected to a component force in the direction of the inside of the engaging cavity 20, thereby driving the sliding plate 21 to slide in the engaging cavity 20, and at the same time compressing the multiple springs 24 to store elastic potential energy. , continue to press the folding plate 17 inward until the two oblique blocks 22 are completely aligned with the two positioning grooves 23. At this time, the two oblique blocks 22 will quickly slide into the two positioning grooves 23 under the elastic force of multiple springs 24, realizing the engagement of the two oblique blocks 22 with the two positioning grooves 23, and the folding plate 17 can be fixed at a vertical angle without shaking or rotating at will, and can be stably maintained in this position, meeting the needs of corresponding usage scenarios such as using it as a temporary support structure outdoors. At the same time, the user can quickly disassemble the table top 18 and replace various types of materials such as aluminum, wood, carbon fiber, etc. during use to meet the needs of people with different personalities.

[0037] like Figure 6 and Figure 7 As shown, an extrusion chamber 25 is integrally formed inside the folding plate 17 and on the opposite sides of the two positioning grooves 23, a piston plate 26 is slidably connected inside the two extrusion chambers 25, a push plate 27 is slidably connected inside the plurality of positioning grooves 23 and on the opposite sides of the two oblique blocks 22, a pressing block 28 is fixedly connected to the upper surfaces of the two piston plates 26, and the upper surfaces of the two pressing blocks 28 extend to the top of the folding plate 17, a plurality of springs 29 are fixedly connected to the lower surfaces of the two extrusion chambers 25 on the lower surfaces of the two piston plates 26, and a gas delivery groove 30 is opened on the lower surfaces of the two extrusion chambers 25 on the opposite sides of the interiors of the two positioning grooves 23;

[0038] By pressing the two pressing blocks 28 with fingers at the same time, the piston plate 1 26 is driven to slide downward in the extrusion chamber 25. During the downward sliding process of the piston plate 1 26, the air in the extrusion chamber 25 will be compressed, and the spring 29 will be further compressed. After being compressed, the spring 29 stores elastic potential energy, and the compressed air enters the positioning groove 23 through the air supply groove 30, so that the two push plates 27 can be controlled to slide back to back, and the two oblique blocks 22 can be pushed out of the two positioning grooves 23 by the two push plates 27, so that the fixation of the folding plate 17 can be cancelled. At this time, the folding plate 17 can be used by turning it downward, so that the user can use it conveniently through the set table board 18 to immediately perform office or other daily needs and other operations.

[0039] like Figure 1 and Figure 5 As shown, a control cavity 34 is integrally formed inside the folding plate 17, a circular groove 35 is provided on the front surface of the folding plate 17 and located in front of the control cavity 34, a rotating disc 36 is provided inside the circular groove 35, a worm 37 is rotatably connected to the rear surface of the control cavity 34 through a rotating shaft, the center of the front surface of the worm 37 is fixedly connected to the center of the rear surface of the rotating disc 36, a receiving groove 38 is provided on the front surface of the folding plate 17 and located on the left and right sides of the circular groove 35, a rotating rod 39 is rotatably connected to the opposite sides of the two receiving grooves 38 through a rotating shaft, a bracket 40 is fixedly connected to the outer side wall of the rotating rod 39 and located inside the two receiving grooves 38, a worm wheel 41 is fixedly connected to the outer side wall of the rotating rod 39 and located inside the control cavity 34, the outer side wall of the worm wheel 41 is meshedly connected to the outer side wall of the worm 37, and a rectangular block 42 is fixedly connected to the front surface of the rotating disc 36;

[0040] When the table top 18 moves to a certain angle along with the rotation of the folding plate 17, the user can rotate the rotating disk 36 by holding the set rectangular block 42. The rotation of the rotating disk 36 can drive the worm wheel 41 to rotate through the set worm 37. The rotation of the worm wheel 41 can rotate the two brackets 40 inside the two storage slots 38 through the set rotating rod 39 until the two brackets 40 are vertical to the ground. In this way, the table top 18 can be stably supported by the two brackets 40, which is convenient for people to use. At the same time, the self-locking property of the worm 37 and the worm wheel 41 can prevent the angles of the two brackets 40 from changing during use, thereby improving the stability of the table top 18. After use, the rotating disk 36 can be rotated in the opposite direction to simultaneously store the two brackets 40 into the two storage slots 38, thereby improving the overall aesthetics of the appearance of the trolley case.

[0041] like Figure 1 As shown, the outer side walls of the two upper transverse tubes 1 3 and the two upper transverse tubes 2 4 are symmetrically provided with tube clamps 31;

[0042] The multiple tube clips 31 can be used to fix some additional items. For example, when traveling, some thin items that are not convenient to put into the trolley case, such as a folding umbrella, a map, light clothes, etc., can be tied to the tube clips 31 by ropes, rubber bands, etc., thereby making full use of the space outside the trolley case, increasing the overall storage capacity, and making it more convenient to carry items when traveling.

[0043] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
