[0028] In this way, the limit assembly is used to improve the stability of the telescopic rod at various lengths, preventing the telescopic rod from accidentally shrinking and causing bags hung on the hook or handle assembly and cups or electronic devices placed on the handle assembly to fall.

[0029] In one embodiment, the sliding member is provided with a limiting slot, and the limiting assembly also includes a driving member capable of sliding relative to the inner rod along the length direction of the telescopic rod, and the driving member includes a sliding portion slidably matched with the limiting slot; when the driving member slides along the length direction of the telescopic rod, the sliding portion slides in the limiting slot, so that the sliding member slides relative to the inner rod along a third preset direction.

[0030] With such arrangement, the structures of the driving member and the sliding member are simple, thus avoiding increasing the overall volume of the telescopic rod.

[0031] In one embodiment, the limiting slide groove includes a limiting section and an inclined section that are interconnected, the limiting section extends along the length direction of the telescopic rod, and when the sliding part slides in the inclined section, the sliding member slides relative to the inner rod along a third preset direction.

[0032] With such arrangement, when the sliding portion is located in the limit section, even if the user shakes the telescopic rod significantly or presses the limit piece on the outside of the outer rod, the limit piece will not fall out of the limit hole and the telescopic rod cannot be extended or retracted, thereby preventing the telescopic rod from being accidentally extended or retracted, thereby improving the safety of the use of the pull rod.

[0033] The utility model also provides a suitcase, comprising a case body and the pull rod as described above, wherein the pull rod is arranged on the case body.

[0034] In one of the embodiments, the top wall of the box is provided with a first receiving groove for accommodating the handle assembly, and the size of the first receiving groove is greater than or equal to the size of the handle assembly.

[0058] When people go out, they may need to carry a shoulder bag, backpack, computer bag or shopping bag while pulling the handle of the suitcase, which makes it inconvenient to move. Some existing suitcases have hooks for hanging bags on the side of the suitcase or the side of the handle. However, when people walk with the suitcase, they are likely to hit the bag or the hook, causing the bag to fall off, which is inconvenient to use.

[0059] In order to solve the above problems, Figures 1 to 11 As shown, the utility model first provides a pull rod 100 to facilitate users to hang bags on a suitcase.

[0060] like Figures 3 to 5 As shown, specifically, the pull rod 100 includes a connecting rod assembly 10, a handle assembly 20 and a hook 30, wherein: the handle assembly 20 includes a first preset direction (such as Figure 3 The first handle 21 extending in the ±X-axis direction (as shown) and the first handle 21 connected to the first handle 21 and extending in the horizontal direction (as shown Figure 3 The first handle 21 is connected to the connecting rod assembly 10; the hook 30 is arranged on the side of the second handle 22 away from the first handle 21 and can rotate relative to the second handle 22. The hook 30 has a storage state and a use state. In the storage state, the hook 30 extends along the first preset direction. In the use state, part of the hook 30 protrudes from the upper surface of the second handle 22.

[0061] In the pull rod 100 provided in the embodiment of the utility model, when a bag needs to be hung, the hook 30 is rotated to Figure 5 In the use state shown, part of the hook 30 protrudes from the upper surface of the second handle 22, and the user can hang the shoulder strap or handle of the bag on the hook 30 to ensure the stability of the bag when it is hung on the hook 30, so that the user does not need to carry the bag while pulling the pull rod 100 of the suitcase; because the hook 30 is set on the handle assembly 20, the height is higher than that of hanging the bag on the side of the suitcase, so that the user can avoid hitting the bag or the hook 30 when walking with the suitcase, avoiding affecting the user's normal walking, and because the hook 30 is set on the side of the second handle 22 away from the first handle 21, it can also avoid that the hook 30 affects the user's grip on the first handle 21. When the bag does not need to be hung, the hook 30 is rotated to the position as shown in the figure. Figure 4 In the storage state shown, the hook 30 extends along the ±X axis direction, preventing the hook 30 from always protruding from the first handle 21 or the outer surface of the suitcase, thereby increasing the overall size of the suitcase or causing the user to easily bump into the hook 30, thereby ensuring the neat appearance of the hook and the suitcase.

[0062] In the illustrated embodiment, in the use state, the extension direction of the hook 30 is perpendicular to the ±X axis, that is, Figure 5 In the case where the overall length of the hook 30 is constant, when the hook 30 extends in the vertical direction, the longer the length of the portion of the hook 30 protruding from the upper surface of the second handle 22 is, the more stable the bag is hung on the hook 30. In addition, in order to avoid increasing the overall volume of the pull rod 100 or the suitcase, the plane where the first handle 21 and the second handle 22 are located is parallel to the plane where the first handle 21 and the second handle 22 are located. Figure 3 In other embodiments, when in use, the extension direction of the hook 30 may also be at an acute angle or an obtuse angle to the ±X axis, as long as part of the hook 30 protrudes from the upper surface of the second handle 22 and the protruding part can ensure the stability of the hanging bag, and the embodiment of the utility model is not specifically limited here.

[0063] like Figure 5 and Figure 7 As shown, the hook 30 includes a rotating part 31 and a hook part 32 connected to each other, the rotating part 31 is rotatably connected to the second handle 22, and in the use state, at least part of the hook part 32 protrudes from the upper surface of the second handle 22. The rotating part 31 can be set as a rotating shaft, and a rotating hole is provided on the side of the second handle 22 away from the first handle 21, and the rotating shaft is inserted in the rotating hole and can rotate relative to the second handle 22; or the rotating shaft can be protruded on the side of the second handle 22 away from the first handle 21, and a rotating hole is provided on the rotating part 31, and the rotating shaft is inserted in the rotating hole, and the rotating part 31 can rotate relative to the rotating shaft. The structure of the hook 30 is simple, and it is convenient for the user to control the hook 30 to switch between the storage state and the use state.

[0064] like Figure 4 , Figure 5 and Figure 7 As shown, there are two hook portions 32, which are arranged on both sides of the rotating portion 31. In the use state, any hook 30 protrudes from the upper surface of the second handle 22. Figure 4 In the storage state shown in FIG. 1 , the user can control the hook 30 to rotate in the +W or -W direction to the position shown in FIG. Figure 5 In the use state shown, any hook portion 32 protrudes from the upper surface of the second handle 22. Similarly, the user can also control the hook 30 to rotate along the -W or +W direction to the storage state in the use state. The user can control the rotation direction of the hook 30 according to his own habits, so as to facilitate the use of different groups of people. In addition, the two hook portions 32 are symmetrically arranged, which can also improve the overall aesthetics of the hook 30 and the pull rod 100.

[0065] like Figure 4 , Figure 5 and Figure 8 As shown, in the storage state, the dimension a of the hook portion 32 along the first preset direction satisfies 20mm≤a≤100mm. Wherein, a can be any value within the range of 20mm to 100mm, such as 20mm, 21mm, 22mm...99mm, 100mm, etc. a≥20mm, in the use state, the portion of the hook portion 32 protruding from the upper surface of the second handle 22 can ensure the stability of the hanging bag; a≤100mm, to avoid the length of the hook portion 32 being too long and protruding from both ends of the first handle 21 in the storage state, thereby ensuring the neat appearance of the pull rod 100.

[0066] like Figure 6 to Figure 7As shown, one of the second handle 22 and the hook 30 is provided with an arc-shaped slide groove 221, and the other is provided with a slider 33. When the hook 30 rotates relative to the second handle 22, the slider 33 is slidably disposed in the arc-shaped slide groove 221. The slider 33 cooperates with the arc-shaped slide groove 221 to limit the rotation range of the hook 30, so that the user can control the hook 30. At least when the hook 30 is rotated to the use state, the slider 33 can abut against the side wall of one end of the arc-shaped slide groove 221 to limit the hook 30 from sliding further relative to the second handle 22, so that the user can align the hook 30 when rotating the hook 30 to the use state.

[0067] like Figure 6 to Figure 7 As shown, the bottom wall of the arc-shaped slide groove 221 is arranged with a plurality of limit grooves 222 at intervals. In the storage state and the use state, the slider 33 is respectively clamped in the corresponding limit groove 222. The slider 33 cooperates with the limit groove 222 to improve the stability and reliability of the hook 30 in the use state and the storage state, thereby improving the stability and reliability of the bag when it is hung on the hook 30, and preventing the hook 30 from accidentally rotating relative to the second handle 22 and causing the bag to fall and be damaged. In addition, when the slider 33 is clamped in the limit groove 222, it can also remind the user to rotate in place, thereby further facilitating the user to align the hook 30.

[0068] When it is necessary to adjust the hook 30 to switch between the storage state and the use state, first pull the hook 30 to the side away from the second handle 22 so that the slider 33 disengages from the limiting groove 222, and then control the hook 30 to rotate along the ±W direction relative to the second handle 22 so that the slider 33 slides in the arc-shaped slide groove 221. When the hook 30 is rotated into place, the slider 33 corresponds to the limiting groove 222, and the hook 30 is pushed toward the second handle 22 so that the slider 33 is stuck in the corresponding limiting groove 222, and the adjustment is completed.

[0069] In the illustrated embodiment, the arc-shaped slide groove 221 has a central angle of 180° and is provided with three limit grooves 222, and the central angle between two adjacent limit grooves 222 is 90°. When the hook 30 is in the storage state, the slider 33 is clamped in the middle limit groove 222, and when the hook 30 is rotated to the use state, the slider 33 is clamped in one of the limit grooves 222 on both sides.

[0070] Furthermore, the pull rod 100 further includes an elastic member (not shown) disposed between the hook 30 and the second handle 22. When the slider 33 is disengaged from the limiting groove 222, the elastic member is stretched. When the hook 30 is pulled outward to the side away from the second handle 22, the slider 33 is disengaged from the limiting groove 222, and the elastic member is stretched. When the hook 30 is rotated relative to the second handle 22 along the ±W direction until the slider 33 corresponds to the limiting groove 222, the hook 30 can slide toward the second handle 22 under the action of the elastic force of the elastic member, so that the slider 33 is inserted into the corresponding limiting groove 222, thereby eliminating the step of aligning the slider 33 with the limiting groove 222 and pushing the hook 30 toward the side facing the second handle 22, which is convenient for the user to operate. Of course, when the slider 33 is inserted into the limiting groove 222, the elastic member can also be in a stretched state to improve the stability and reliability of the hook 30 in the storage state and the use state.

[0071] In addition, a guiding slope is provided between the side wall of the limiting groove 222 and the bottom wall of the arc-shaped sliding groove 221. When the slider 33 is clamped in the limiting groove 222, the user can apply a large torsional force to the hook 30, so that the hook 30 can rotate relative to the second handle 22 while sliding toward the side away from the second handle 22 under the action of the guiding slope, so that the slider 33 can escape from the limiting groove 22, thereby eliminating the step of the user pulling the hook 30 toward the side away from the second handle 22, thereby facilitating user operation.

[0072] like Figure 4 and Figure 8 As shown, the second handle 22 includes a handle section 223 and two connecting sections 224 respectively connected to the two ends of the handle section 223. The handle section 223 and the first handle 21 are connected along the second preset direction ( Figure 4The hook 30 is arranged at intervals in the ±Y-axis direction shown in the figure, and is arranged on the side of the handle section 223 away from the first handle 21; the ends of the two connecting sections 224 away from the handle section 223 are respectively connected to the two ends of the first handle 21, so that the first handle 21 and the second handle 22 are surrounded to form a storage space. The user can place other items such as cups in the storage space formed by the first handle 21 and the second handle 22. The first handle 21 and the second handle 22 are used to limit the cup to prevent the cup from falling, so that the user does not need to hold the cup all the time, and the user's legs will not hit the cup when walking with the suitcase, which is convenient to use. In addition, placing the cup in the storage space is higher than placing it on the side of the suitcase, which is convenient for the user to pick up, and can also serve as a reminder to the user, so that the bottle or cup is not easily forgotten. It can be understood that the outer diameter of most cups gradually increases from the bottom to the cup mouth, the diameter of some areas of the bottom of the cup needs to be smaller than the distance between the first handle 21 and the second handle 22, and the diameter of the remaining areas needs to be larger than the distance between the first handle 21 and the second handle 22, so that the cup can pass through the storage space and be placed between the first handle 21 and the second handle 22.

[0073] like Figure 8 As shown, a recess 225 is provided on the side of the second handle 22 facing the storage space. The recess 225 may be arc-shaped. When a cup is placed in the storage space, the recess 225 can limit the position of the cup to prevent the cup from tipping over or sliding along the ±X axis direction. The side of the second handle 22 facing away from the storage space may be provided with an arc-shaped structure corresponding to the recess 225, so that the thickness of the second handle 22 is thinner and the overall weight of the second handle 22 is reduced. The hook 30 may also be provided with an arc-shaped structure that fits the side of the second handle 22 facing away from the storage space, so that the structure of the handle assembly 20 and the hook 30 is more beautiful. Of course, a recess 225 may also be provided on the side of the first handle 21 facing the storage space, so that the user can feel more comfortable when holding the first handle 21 while limiting the position of the cup.

[0074] like Figure 4 and Figure 8 As shown, in the illustrated embodiment, both ends of the handle section 223 are provided with hanging grooves 2231 extending along the first preset direction, and the projections of the two hanging grooves 2231 along the first preset direction overlap. When the shoulder strap or handle of the bag is long, the shoulder strap or handle of the bag can be hung on the two hanging grooves 2231. The two hanging grooves 2231 can provide two support points for the shoulder strap or handle of the bag, and the distance between the two support points is large, thereby improving the stability of the bag and reducing damage to the shoulder strap or handle of the bag. In another embodiment, the two connecting sections 224 are both provided with hanging grooves 2231 extending along the first preset direction, and the projections of the two hanging grooves 2231 along the first preset direction overlap.

[0075] Of course, the two hanging grooves 2231 can also be used to place electronic devices such as mobile phones and tablet computers. The two hanging grooves 2231 can improve the stability of supporting electronic devices, prevent the electronic devices from tipping over or falling, and will not limit the size of the electronic devices along the ±X axis direction. When the hanging grooves 2231 are used to place electronic devices, due to the limited depth of the hanging grooves 2231, the hook 30 can be rotated to the use state, so that the hook part 32 can support the electronic device at the rear side, further improving the stability and safety of the electronic device when in use.

[0076] The handle section 223 and the hook 30 are preferably metal parts to ensure the strength of the handle section 223 and the hook 30, and also to ensure the reliability when hanging bags or placing electronic devices. The connecting section 224 can be made of the same material as the handle section 223, for example, the handle section 223 and the connecting section 224 are set as an integrated structure to ensure the connection strength; the connecting section 224 can also be made of a different material from the handle section 223 to reduce the overall weight of the handle assembly 20.

[0077] like Figure 4 As shown, a limiting rib 2232 is protruded inwardly from the upper edge of the hanging slot 2231. The limiting rib 2232 extends along the ±X axis direction and is protruded from one side edge of the hanging slot 2231 toward the other side edge. The limiting rib 2232 can reduce the opening size of the upper side of the hanging slot 2231 to prevent the shoulder strap or handle of the bag from accidentally falling out of the hanging slot 2231, and can also improve the stability of thin electronic devices when they are mounted in the hanging slot 2231.

[0078] like Fig.11 As shown, the width b of the hanging groove 2231 along the second preset direction satisfies 10mm≤b≤15mm. Among them, b can be any value within the range of 10mm to 15mm, such as 10mm, 10.5mm, 11mm, ... 14mm, 15mm, etc. When the size of the hanging groove 2231 in the ±Y axis direction satisfies 10mm to 15mm, it can ensure that bags with straps or handles of different widths can be hung in the hanging groove 2231, and it can also ensure that electronic devices such as mobile phones and tablets of different thicknesses, or electronic devices with protective shells can be placed in the hanging groove 2231, and the scope of application is wide.

[0079] like Figure 6As shown, the depth c of the hanging groove 2231 satisfies 12mm≤c≤38mm. Among them, c can be any value within the range of 12mm to 38mm, such as 12mm, 13mm, 14mm...37mm, 38mm, etc. When the size of the hanging groove 2231 in the ±Z axis direction satisfies 12mm to 38mm, it can ensure the stability of the shoulder strap or handle of the bag when it is hung in the hanging groove 2231, and prevent the shoulder strap or handle of the bag from accidentally falling out of the hanging groove 2231. It also ensures the stability of electronic devices such as mobile phones and tablets when placed in the hanging groove 2231, and prevents the electronic devices from tipping over or falling. At the same time, limiting the size of the hanging groove 2231 in all directions can also prevent the size of the second handle 22 from being too large, which will cause the overall size of the pull rod 100 to be too large.

[0080] like Figure 3 and Fig. 9 As shown, the connecting rod assembly 10 includes a base 11 and a telescopic rod 12 extending from the base 11, and one end of the telescopic rod 12 away from the base 11 is connected to the first handle 21. Figure 3 The telescopic rod 12 extends along the ±Z axis shown in the figure, and can be extended and retracted in the ±Z direction. A button 211 for controlling the extension and retraction of the telescopic rod 12 is provided on the first handle 21, and the user can control the extension and retraction of the telescopic rod 12 by pressing the button 211. The handle assembly 20 and the hook 30 can adjust the height under the extension and retraction of the telescopic rod 12, so as to facilitate users of different heights to use in different environments. For example, when a user walks with the suitcase pulled by the handle assembly 20, the telescopic rod 12 can be pulled up. When the telescopic rod 12 is in the retracted state, the upper surface of the handle assembly 20 is flush with the upper surface of the case 200 of the suitcase, so as to avoid increasing the overall volume of the suitcase.

[0081] The number of telescopic rods 12 can be two, and the two telescopic rods 12 are arranged at intervals along the ±X axis direction, and the ends of the two telescopic rods 12 away from the base 11 are respectively connected to the two ends of the first handle 21. Of course, the number of telescopic rods 12 can also be one, and the end of the telescopic rod 12 away from the base 11 is connected to the middle position of the first handle 21, as long as the overall strength of the pull rod 100 and the stability of the handle assembly 20 when it is lifted and lowered along the ±Z axis direction can be guaranteed, the embodiment of the utility model does not make specific restrictions here.

[0082] like Figure 3 , Fig. 9 and Fig.10As shown, the telescopic rod 12 includes an outer rod 121, an inner rod (not shown) and a limit assembly 122. Among them, the number of inner rods can be one, two or more, and the multiple inner rods are sequentially set from the inside to the outside, and the cross-sectional size of the inner rods gradually increases, and the cross-sectional size of the outer rod 121 is greater than the cross-sectional size of the outermost inner rod. One end of the outer rod 121 is connected to the base 11, and the end of the innermost inner rod away from the base 11 is connected to the first handle 21. The number of limit assemblies 122 is set corresponding to the number of inner rods, and adjacent inner rods or the outermost inner rod and the outer rod 121 are connected by a limit assembly 122. The limit assembly 122 has a limit state and an unlock state. In the limit state, the telescopic rod 12 cannot be extended and retracted along the ±Z axis direction. In the unlock state, the inner rod can be extended and retracted along the ±Z axis direction relative to the outer rod 121. The button 211 on the first handle 21 is used to control the multiple limit assemblies 122 to switch between the limit state and the unlock state synchronously.

[0083] For ease of description, the following description is made by taking the telescopic rod 12 as an example, wherein the telescopic rod 12 includes an inner rod and a stopper assembly 122. One end of the outer rod 121 is connected to the base 11, the inner rod is slidably disposed in the outer rod 121, and the end of the inner rod away from the base 11 is connected to the first handle 21; the side wall of the outer rod 121 is provided with a plurality of stopper holes 1211 arranged at intervals along the length direction of the telescopic rod 12; the stopper assembly 122 is provided on the inner rod and includes a sliding member 1221 and a stopper 1222 protruding from the sliding member 1221; the sliding member 1221 can be moved relative to the inner rod along a third preset direction ( Fig.10 The inner rod 1221 is configured to slide along the ±V axis direction (as shown) so that the limiting member 1222 can slide into or out of any limiting hole 1211. The ±V axis direction is a direction parallel to the XY plane, and can be parallel to the ±X axis. When the user presses the button 211, the button 211 can drive the sliding member 1221 to slide along the -V axis direction so that the limiting member 1222 can be out of the limiting hole 1211, the limiting assembly 122 is in an unlocked state, and the inner rod can slide and retract along the ±Z axis directions relative to the outer rod 121. After the user releases the button 211, the button 211 can automatically reset and drive the sliding member 1221 to slide along the +V axis direction so that the limiting member 1222 is inserted into the corresponding limiting hole 1211, the limiting assembly 122 is in a limited state, and the inner rod cannot slide and retract along the ±Z axis directions relative to the outer rod 121. The limiting assembly 122 is used to improve the stability of the telescopic rod 12 at various lengths to prevent the telescopic rod 12 from accidentally contracting and causing bags hung on the hook 30 or the handle assembly 20 and items such as cups or electronic devices placed on the handle assembly 20 to fall.

[0084] like Figure 10 to Figure 11 As shown, the sliding member 1221 is provided with a limiting sliding groove 12211, and the limiting assembly 122 also includes a limiting sliding groove 12211 that can be relative to the inner rod along the length direction of the telescopic rod 12 ( Fig.10The driving member 1223 slides along the length direction of the telescopic rod 12 (in the ±Z-axis direction shown in the figure), and the driving member 1223 includes a sliding portion 12231 that slides with the limiting slide groove 12211; when the driving member 1223 slides along the length direction of the telescopic rod 12, the sliding portion 12231 slides in the limiting slide groove 12211, so that the sliding member 1221 slides along the third preset direction relative to the inner rod. When the user presses the button 211, the button 211 can drive the driving member 1223 to slide along the -Z direction, and the sliding portion 12231 slides in the limiting slide groove 12211 to drive the sliding member 1221 to slide along the -V-axis direction, so that the limiting member 1222 escapes from the limiting hole 1211. After the user releases the button 211, the button 211 automatically resets and drives the driving member 1223 to slide along the +Z direction, and the sliding portion 12231 slides in the limiting sliding groove 12211 to drive the sliding member 1221 to slide along the +V axis direction, so that the limiting member 1222 is inserted into the corresponding limiting hole 1211. The driving member 1223 and the sliding member 1221 have a simple structure, which avoids increasing the overall volume of the telescopic rod 12.

[0085] like Fig.11 As shown, the limiting slide groove 12211 includes a limiting section 12211a and an inclined section 12211b which are connected to each other. The limiting section 12211a extends along the length direction of the telescopic rod 12. When the sliding part 12231 slides in the inclined section 12211b, the sliding member 1221 slides relative to the inner rod along the third preset direction. In the limited state, the sliding part 12231 is located in the limited section 12211a, and the sliding member 1221 cannot slide along the ±V axis direction. At this time, even if the user shakes the telescopic rod 12 significantly or presses the limiting member 1222 outside the outer rod 121, the limiting member 1222 will not fall out of the limiting hole 1211, and the telescopic rod 12 cannot be extended or retracted; only when the user presses the button 211 on the first handle 21 can the driving member 1223 be driven to slide in the -Z axis direction, and the sliding part 12231 will first slide a distance in the limited section 12211a, and then slide from the limited section 12211a to the inclined section 12211b, thereby driving the sliding member 1221 to slide along the -V axis direction, so that the limiting member 1222 falls out of the limiting hole 1211. This can further prevent the telescopic rod 12 from accidentally extending or retracting, and improve the safety of the pull rod 100.

[0086] like Figure 10 to Figure 11As shown, the limiting assembly 122 also includes a base 1224, the base 1224 is provided with a sliding groove 12241 extending along the ±V axis direction, and the sliding member 1221 is slidably arranged in the sliding groove 12241 to limit the sliding direction of the sliding member 1221, so as to ensure that the sliding member 1221 can only slide along the ±V axis. The limiting assembly 122 also includes a stopper 1225 arranged in the sliding groove 12241 and fixed relative to the base 1224, and the sliding member 1221 is provided with a stopper sliding groove 12212 extending along the ±Z axis direction, and the stopper 1225 can slide in the stopper sliding groove 12212. When the sliding member 1221 slides to the limiting state and the unlocking state, the two side surfaces of the stopper 1225 can respectively abut against the two ends of the stopper sliding groove 12212 to limit the sliding member 1221 from continuing to slide, thereby limiting the sliding range of the sliding member 1221.

[0087] like Figure 1 to Figure 2 As shown, the embodiment of the utility model also provides a luggage case, comprising a case body 200 and the above-mentioned pull rod 100, and the pull rod 100 is arranged on the case body 200. Specifically, the top wall of the case body 200 is provided with a first receiving groove 201 for accommodating the handle assembly 20, and the size of the first receiving groove 201 is greater than or equal to the size of the handle assembly 20. The first receiving groove 201 can prevent the handle assembly 20 from protruding from the case body 200 and increasing the overall volume of the luggage case. Since the handle, wheels, etc. of the luggage case are usually calculated when calculating the size of the luggage case, the pull rod 100 does not protrude from the case body 200, so that the luggage case can have a larger capacity without changing the overall size. In addition, there is a certain distance between the first handle 21 and the second handle 22 and the bottom wall of the first receiving groove 201, so that the user can grasp the first handle 21, and the telescopic rod 12 is in a retracted state. When a cup is placed in the storage space, the bottom wall of the first receiving groove 201 can also support the cup.

[0088] like Figure 1 to Figure 2 As shown, the side wall of the box body 200 is provided with a first receiving groove 201 connected to the first receiving groove 201 and extending along the height direction of the luggage box ( Figure 1 The second receiving groove 202 extending in the ±Z-axis direction (as shown in the figure) is provided on the bottom wall of the box body 200, and the third receiving groove 203 communicating with the second receiving groove 202 is provided, the telescopic rod 12 is embedded in the second receiving groove 202, and the base 11 is embedded in the third receiving groove 203. The pull rod 100 is arranged on the outside of the box body 200, and the handle assembly 20 and the base 11 are respectively arranged on the top wall and the bottom wall of the box body 200, so that the telescopic rod 12 can reach the longest length, thereby extending the adjustable length of the inner rod and the outer rod 121, so that the suitcase can be suitable for users of different heights and different use environments, further expanding the scope of application.

[0089] like Figure 1 to Figure 2As shown, the inner wall of the third containing groove 203 and the base 11 are surrounded to form a handle portion with an opening. When the suitcase is in a flat state, that is, when the side of the case 200 provided with the telescopic rod 12 is horizontal, the handle portion and the first handle 21 are at the same height, and the user can grasp the first handle 21 and the handle portion with both hands respectively to facilitate lifting the suitcase.

[0090] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
