When going out, people may carry different kinds of items. If the space inside the suitcase cannot be effectively divided according to the size of the items, some space will be wasted. The existing suitcases cannot store different types of items separately. It is also impossible to increase or decrease the volume of the compartments inside the suitcase according to the user's ideas. The existing suitcases can only be divided into two chambers, and cannot be divided into multiple chambers according to the user's ideas.

[0003] Therefore, how to provide a suitcase that can be divided into multiple chambers of different sizes according to user usage is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0004] In view of this, the utility model provides a suitcase that is convenient for travel. The storage space can be reasonably divided according to the items that need to be carried during the travel, so that the items can be stored separately, and the use is flexible and convenient.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a suitcase convenient for travel, comprising:

[0006] A box body, wherein a plurality of convex strips are provided on inner walls on two opposite sides of the box body;

[0007] A plurality of partition plates are provided and are respectively slidably connected to the inner side wall of the box body and divide the interior of the box body into a plurality of storage cavities. A plurality of clamp mechanisms for clamping the convex strips are provided at both side ends of the partition plates. The clamp mechanisms clamp the convex strips on the corresponding sides and limit the sliding position of the partition plates in the box body.

[0008] A telescopic plugboard assembly is located in the storage cavity and is slidably connected to a partition plate or a box wall near the side, and the telescopic plugboard assembly is used to separate the storage cavity.

[0009] The beneficial effect of the present invention is that a plurality of slidable partitions are arranged inside the box body, so that the space inside the box can be divided into a plurality of storage cavities as needed, so as to complete the classified storage of different items. On this basis, the storage cavities can be divided by using the telescopic plug-in plate assembly, which optimizes the storage space while also increasing the possibility of storing a variety of items separately, making it as convenient as possible for travelers to use. The position of the partition plate can be limited by the clamp mechanism thereon and the convex strips on the box body to ensure the stability of the divided storage space. The telescopic plug-in plate assembly can adjust its own length without affecting the use of the partition plate, and can also move relative to the partition plate to divide the size of the storage cavity again, which can be adjusted according to actual needs.

[0010] Preferably, the box body is a rectangular structure, and a plurality of convex strips are arranged on the inner side walls and the bottom wall of the long sides of the box body, and the convex strips on the inner side walls of the long sides of the box body are horizontally spaced apart from each other. Avoidance grooves are provided at the two side ends and the bottom end of the partition plate corresponding to the positions of the convex strips, and a tweezers mechanism is installed in the avoidance grooves.

[0011] The resulting technical effect is that the multiple convex strips on the bottom wall and the long side walls of the box body can improve the stability of the partition plate's sliding and the fixity of the partition plate after the position is determined, making it convenient for storing multiple types of items.

[0012] Preferably, the pliers mechanism includes a normally open spring pliers, a pull wire and a drive disk, the spring pliers fixed axis is movably connected in the avoidance groove, the jaw end of the spring pliers is used to clamp the convex strip, the drive end of the spring pliers is connected to one end of the pull wire, the interior of the partition plate is provided with an installation cavity, a wire column is fixed on the cavity wall of the installation cavity and close to the spring pliers, the wire column is used to guide the movement of the pull wire, the movement of the pull wire causes the open end of the spring pliers to close, the action points of the convex strip, the connecting axis of the spring pliers and the wire column are located on the same horizontal line, the drive disk is rotatably connected in the installation cavity and fixedly connected to the other end of the pull wire, the rotation of the drive disk causes the pull wire to move and complete the opening and closing action of the jaw end.

[0013] The resulting technical effect is: the spring pliers are of normally open type, which is convenient for the movement and adjustment of the partition plate. When adjusted into place, the jaw end of the spring pliers can be controlled by the pliers mechanism to clamp the convex strip to achieve the position limitation of the partition plate. The jaw end clamps the convex strip by relying on a pull wire. The rotation of the drive disk can drive the pull wire to move, causing the driving end of the spring pliers to close stably, thereby clamping the spring pliers and the convex strip. Here, in order to improve the clamping effect and stability of the spring pliers, it is necessary to ensure that the convex strip and the connecting axis of the spring pliers on the near side and the point of action of the pull wire are located on the same straight line.

[0014] Preferably, a plurality of wire nodes are provided in the installation cavity and below the center line of the corresponding driving disk, the wire nodes are used to guide the movement of the pulling wires, and the pulling wires on a plurality of spring clamps pass through the wire nodes in parallel, and a buffer spring is connected between the pulling wires and the driving disk.

[0015] The resulting technical effect is: the purpose of the wire node is to guide the direction of the pulling wire, to ensure that the spring clamp on the bottom side can reliably and stably clamp with the convex strip on the bottom wall of the box; the purpose of the buffer spring is to ensure that the pulling force of the pulling wire is within a stable torque range, and will not cause damage to parts due to excessive pulling force of the pulling wire.

[0016] Preferably, a plurality of mutually parallel slide grooves are provided on two opposite inner side walls of the box body, and a plurality of pulleys are provided on both end edges of the partition plate, and the pulleys are adapted to be slidably connected in the slide grooves on the corresponding sides.

[0017] The resulting technical effect is that the cooperation between the slide groove and the pulley is the basis for the stable sliding of the partition plate inside the box.

[0018] Preferably, a torque transmission member is fixed to one side of the driving disk, and a bearing section is provided on the torque transmission member. The torque transmission member is rotatably connected to the side wall of the partition plate through the bearing, and a knob is fixedly connected to one end of the torque transmission member, and the knob is located on the outside of the partition plate. A blocking rod is provided on the inner wall of the installation cavity corresponding to the partition plate, and the blocking rod is used to limit the rotation angle of the torque transmission member. A spring pin is provided on the inner wall of the installation cavity to prevent the torque transmission member from rotating, and the pressing end of the spring pin is located on the outer wall of the partition plate.

[0019] The resulting technical effect is: the driving disk is controlled to rotate by the torque transmission member and the knob, and the rotation limit angle of the torque transmission member directly determines the rotation angle of the driving disk. Because when the spring pliers clamp the convex strip, the pull wire will work with the reverse pulling force, so the anti-rotation effect of the rotating disk is achieved through the cooperation of the torque transmission member, the blocking point and the spring pin. When it is necessary to release the restriction of the spring pliers on the convex strip, press the spring pin to release the restriction on the reverse rotation of the torque transmission member, realize the rotation of the driving disk, reset the pull wire, and open the spring pliers. The moving position of the partition plate can be adjusted subsequently.

[0020] Preferably, the outer contour of the torque transmission member is provided with an eccentric arc segment and a straight line segment, and the two side edges of the torque transmission member corresponding to the straight line segment are provided with slots adapted to engage with the blocking rod, and the edge of one end of the straight line segment of the torque transmission member is rotated a certain angle and then abuts against the blocking rod, and the other end of the eccentric arc segment of the torque transmission member passes over the spring pin. In this state, the spring pin abuts against the other end edge of the straight line segment and prevents the torque transmission member from rotating, and the rotation of the torque transmission member causes the drive disk to rotate 180°.

[0021] The resulting technical effect is that the torque transmission member can only rotate 180°, that is, the driving disk rotates half a circle. The purpose is to make the pull wire move from the lowest point to the highest point. When the pull wire is connected, it is best to install it at the lowest point of the driving disk. In this way, the pull wire has a larger pulling distance. The torque transmission member is prevented from rotating under the obstruction of the spring pin, thereby ensuring the clamping state of the spring pliers.

[0022] Preferably, the telescopic plug-in plate assembly includes a motherboard and a daughterboard, the motherboard is provided with a groove for plugging in the daughterboard, the middle part of the motherboard is rotatably connected with a tension bolt, the tension bolt is provided with a pressure plate for fixing the relative positions of the daughterboard and the motherboard, and the motherboard and the daughterboard are respectively slidably connected to the partition plate on the corresponding side or the inner wall of the box.

[0023] The resulting technical effect is that the motherboard and the daughterboard can be plugged in, and the plug-in position can be adjusted in order to coordinate with the moving position of the partition plate. Of course, the telescopic plug-in plate assembly can slide relative to the partition plate to further divide the internal space size of the storage cavity.

[0024] Preferably, notches are provided on both outer side ends of the motherboard and the daughterboard, and a prying bar is movably installed in the notch. Damping groove belts are provided on the side walls of the partition plate or the box body close to the telescopic plug-in plate assembly. One end of the prying bar is rotated at an angle and connected to a card slot on the damping groove belt to limit the position.

[0025] The resulting technical effect is that the position of the telescopic plug plate assembly relative to the partition plate is limited by the cooperation of the prying bar thereon and the partition plate and the damping groove belt on the box body. When the telescopic plug plate assembly is not in use, it can be placed in the side limit of the box body. The slot can be expanded at the slot end, or a guide slope can be set to facilitate the introduction of the prying bar.

[0026] Preferably, a groove cavity is provided inside the motherboard and the daughterboard, and a pulling mechanism for controlling the rotation of the prying baffle bar is arranged in the groove cavity, and the pulling mechanism includes a pull rope, a reset spring, a turntable and a turntable angle control lever, the prying baffle bar is fixed-axis rotatably connected to the daughterboard or the motherboard, the other end of the prying baffle bar is connected to the pull rope, one end of the pull rope is fixed to the bottom wall of the groove cavity of the motherboard or the daughterboard through the reset spring, the other end of the pull rope is connected to the turntable, and the turntable is rotatably connected in the groove cavity, one end of the turntable angle control lever is fixedly connected to the turntable and controls the rotation angle of the turntable, and the other end of the turntable angle control lever is located on the outside of the motherboard or the daughterboard.

[0027] The resulting technical effect is that the prying lever can move like a prying plate. When it is necessary to limit the position of the telescopic plug plate assembly, one end of the prying lever is caused to swing through the pulling mechanism and then get stuck in the damping groove belt. When it is not necessary to limit the position of the telescopic plug plate assembly, the rotation restriction of the turntable is released. Under the action of the reset spring, one end of the prying lever is tilted upward to release the clamping fit with the damping groove belt. In this state, the position of the telescopic plug plate assembly can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
