[0021] In addition, the terms "first" and "second" are only for the purpose of explanation, and do not indicate or imply relative importance, nor can it be understood as implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more of these features. In the description of this application, the meaning of "a plurality of" is two or more unless otherwise specifically limited.

[0022] Referring to FIGS. 1 to 8, a carry case provided by an embodiment of this application will be described.

[0023] A carry case comprising a first case 10 that can be opened or closed and a second case 20, and the first case 10 and the second case 20 are opened or closed by a main fastener 50. A telescopic rod 30 is provided on the first case 10 or the second case 20, and casters 40 are provided on the side wall at one end of the case away from the telescopic rod 30 and the second case 20, so that it is convenient for the user to pull the carry case on the ground by the telescopic rod 30.

[0024] In this application, this carry case further comprises a capacity expansion fastener 60 and a reinforcement structure 70.

[0025] The capacity expansion fastener 60 is connected to the first case 10 and the second case 20, is located inside the main fastener 50, and the width size of the capacity expansion fastener 60 is larger than the width size of the main fastener 50.

[0026] In the present application, along the width direction of the capacity expansion fastener 60, the width sizes of the two fastener tapes of the capacity expansion fastener 60 are both larger than the width sizes of the two fastener tapes of the main fastener 50.

[0027] The reinforcement structure 70 is connected to the first case 10 and the second case 20, has a first length size and a second length size, and the first length size is smaller than the second length size.

[0028] In the present application, the reinforcement structure 70 is adjacent to the caster 40 of the carry case and is provided on the side wall having the main fastener 50 and the capacity expansion fastener 60, and is for connecting the first case 10 and the second case 20 simultaneously. The number of the reinforcement structures 70 is plural, and the plural reinforcement structures 70 are provided at intervals.

[0029] Specifically, the number of the reinforcement structures 70 is two.

[0030] When the main fastener 50 closes the first case 10 and the second case 20, the reinforcement structure 70 becomes the first length size. When the main fastener 50 opens and the capacity expansion fastener 60 closes the first case 10 and the second case 20, the reinforcement structure 70 becomes the second length size.

[0031] The carrying case provided by this application, compared with the existing technology, closes the first case 10 and the second case 20 of the carrying case by the main fastener 50, and a capacity expansion fastener 60 is provided inside the main fastener 50. The width of the capacity expansion fastener 60 is larger than the width of the main fastener 50. When the main fastener 50 is opened and the capacity expansion fastener 60 closes the first case 10 and the second case 20, the capacity expansion of the carrying case is realized. The carrying case is provided with a reinforcing structure 70. The width of the reinforcing structure 70 can be adjusted when the main fastener 50 or the capacity expansion fastener 60 closes the carrying case. When the capacity expansion fastener 60 closes the first case 10 and the second case 20, the reinforcing structure 70 ensures the reliability of the connection between the first case 10 and the second case 20 and prevents the capacity expansion fastener 60 from being damaged.

[0032] In this application, the reinforcing structure 70 includes a first connecting component 71, a second connecting component 72, and a telescopic component 73.

[0033] The first connecting component 71 has a rectangular plate-like structure, and the first connecting component 71 is connected to one of the first case 10 and the second case 20.

[0034] The second connecting component 72 also has a rectangular plate-like structure. The second connecting component 72 is connected to the other of the first case 10 and the second case 20, and the position of the second connecting component 72 corresponds to the position of the first connecting component 71.

[0035] The telescopic component 73 also has a rectangular plate-like structure, and the telescopic component 73 is slidably connected to the first connecting component 71 and the second connecting component 72.

[0036] The first connecting component 71 has a first position and a second position with respect to the second connecting component 72. When the first connecting component 71 is in the first position and the first case 10 and the second case 20 are closed by the main fastener 50, the distance between the first connecting component 71 and the second connecting component 72 becomes the first length size.

[0037] When the first connecting component 71 is in the second position, at this time, the main fastener 50 is in an open state, the capacity expansion fastener 60 closes the first case 10 and the second case 20, and the distance between the first connecting component 71 and the second connecting component 72 becomes the second length size.

[0038] In the present application, the first connecting component 71 is provided with a first sliding groove 711, and a first opening 712 is provided on one side of the first sliding groove 711 facing the second connecting component 72. The second connecting component 72 is provided with a second sliding groove 721, and a second opening 722 is provided on one side of the second sliding groove 721 facing the first connecting component 71. The telescopic component 73 includes opposite first end S1 and second end S2. The first end S1 is connected to slide in the first sliding groove 711, and the second sliding groove S2 is connected to slide in the second sliding groove 721.

[0039] A rectangular third opening 713 is provided on one side wall of the first connecting component 71 facing the carry case, and a rectangular fourth opening 723 is provided on one side wall of the second connecting component 72 facing the carry case.

[0040] In the present application, a first engaging block 731 is provided convexly on the first end S1, and a second engaging block 732 is provided convexly on the second end S2.

[0041] Specifically, the first engaging block 731 extends along a direction perpendicular to the sliding direction of the telescopic component 73, and the first engaging block 731 is provided convexly on two side walls of the first end S1 parallel to the sliding direction of the telescopic component 73. That is, the first engaging block 731 is symmetrically provided on the first end S1 with respect to the sliding direction of the telescopic component 73. The length size of the first opening 712 is smaller than the length size between the ends of the two first engaging blocks 731 along the direction perpendicular to the sliding direction of the telescopic component 73, so that the two first engaging blocks 731 are easily engaged on the side away from the second connecting component 72 of the side wall with the first opening 712.

[0042] The second engaging block 732 extends along a direction perpendicular to the sliding direction of the telescopic component 73, and the second engaging block 732 is provided convexly on two side walls of the second end S2 parallel to the sliding direction of the telescopic component 73. That is, the second engaging block 732 is provided symmetrically with respect to the second end S2 with respect to the sliding direction of the telescopic component 73. The length size of the second opening 722 is smaller than the length size between the ends of the two second engaging blocks 732 along the direction perpendicular to the sliding direction of the telescopic component 73, so that the two second engaging blocks 732 are easily engaged on the side away from the first connecting component 71 of the side wall where the second opening 722 is located.

[0043] In the present application, elastic ribs 74 are provided convexly on both the first end S1 and the second end S2.

[0044] Specifically, the elastic rib 74 is provided at an angle in the sliding direction of the telescopic component 73. When the first end S1 abuts against the side wall of one end of the first sliding groove 711 away from the first opening 712, the elastic rib 74 located at the first end S1 can easily buffer the telescopic component 73. When the second end S2 abuts against the side wall of one end of the second sliding groove 721 away from the second opening 722, the elastic rib 74 located at the second end S2 can easily buffer the telescopic component 73. At the same time, when the main fastener 50 closes the first case 10 and the second case 20, that is, when the distance between the first connecting component 71 and the second connecting component 72 is the first length size, the elastic rib 74 located at the first end S1 abuts against the side wall of one end of the first sliding groove 711 away from the first opening 712, and the elastic rib 74 located at the second end S2 abuts against the side wall of one end of the second sliding groove 721 away from the second opening 722, thereby preventing the telescopic component 73 from sliding with respect to the first connecting component 71 and the second connecting component.

[0045] In the present application, a chamfer 741 is provided at one end of the elastic rib 74 away from the telescopic component 73, that is, a chamfer 741 is provided on one side of the elastic rib 74 located at the first end S1, facing the side wall at one end of the first sliding groove 711 away from the first opening 712, and a chamfer 741 is also provided on one side of the elastic rib 74 located at the second end S2, facing the side wall at one end of the second sliding groove 721 away from the second opening 722.

[0046] In the present application, the elastic ribs 74 are provided symmetrically with respect to the sliding direction of the telescopic component 73. That is, two elastic ribs 74 are provided at both the first end S1 and the second end S2, and the two elastic ribs 74 provided at the first end S1 and the second end S2 are provided symmetrically with respect to the sliding direction of the telescopic component 73.

[0047] In the present application, this reinforcing structure 70 further includes a first connection rod 75 and a second connection rod 76. The first connection rod 75 is provided convexly on the first connection component 71 and is for connecting to one of the first case 10 and the second case 20. The second connection rod 76 is provided convexly on the second connection component 72 and is for connecting to the other of the first case 10 and the second case 20.

[0048] Specifically, for the sake of easy explanation, the case where the first connection component 71 is connected to the first case 10 and the second connection component 72 is connected to the second case 20 will be described as an example below.

[0049] The first case 10 is provided with a first insertion connection hole for inserting and connecting the first connection rod 75, and the first connection rod 75 is connected in the first insertion connection hole to fix the first connection component 71 to the first case 10. The second case 20 is provided with a second insertion connection hole for inserting and connecting the second connection rod 76 to fix the second connection component 72 to the second case 20.

[0050] The number of the first connecting rod 75 and the second connecting rod 76 is two each, and the two first connecting rods 75 and the two second connecting rods 76 are both provided symmetrically with respect to the sliding direction of the telescopic component 73. After the two first connecting rods 75 penetrate the first insertion connection holes, they are fixed and connected to the first fixing plate 77 by screws, thereby fixing the first connecting rod 75 to the first box body 10. After the two second connecting rods 76 penetrate the second insertion connection holes, they are fixed and connected to the second fixing plate by screws, thereby fixing the second connecting rod 76 to the second box body 20.

[0051] In the present application, in order to ensure the sliding distance of the telescopic component 73 between the first connecting component 71 and the second connecting component 72, the telescopic component 73 is provided with a first avoidance groove 733 and a second avoidance groove 734.

[0052] Specifically, the first avoidance groove 733 is provided at the first end S1, and the second avoidance groove 734 is provided at the second end S2. When the telescopic component 73 slides with respect to the first connecting component 71 and the second connecting component 72, the first connecting rod 75 slides with respect to the first avoidance groove 733, and the second connecting rod 76 slides with respect to the second avoidance groove 734.

[0053] The above is only a preferred embodiment of the present application and is not intended to limit the present application. All modifications, equivalent substitutions, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
