[0028] Please see Figs. 1 to 4 The utility model embodiment provides a protective sleeve for assembling articles, the protective sleeve includes first shell 1 and second shell 2, first shell 1 and second shell 2 are assembled and are connected to form the closed assembling space, wherein, first shell 1 is provided with first clamping groove 11, and second shell 2 is provided with the first clamping structure 21 corresponding with first clamping groove 11, first clamping structure 21 can be moved along the first direction between the first position and the second position of first clamping groove 11, when first clamping structure 21 is located at the first position, first clamping structure 21 is clamped in first clamping groove 11, to make first shell 1 and second shell 2 fixed connection, when first clamping structure 21 is located at the second position, first clamping structure 21 can be away from first clamping groove 11, to make first shell 1 and second shell 2 can be separated.

[0029] In the utility model embodiment, the protective sleeve includes first shell 1 and second shell 2, first shell 1 is provided with first clamping groove 11, and second shell 2 is provided with first clamping structure 21. When first clamping structure 21 is moved from the second position to the first position of first clamping groove 11 along the first direction, first clamping structure 21 is clamped in first clamping groove 11, so that first shell 1 and second shell 2 are relatively fixed, so that the assembly connection of first shell 1 and second shell 2 can be realized to form an assembly space, and the assembly space can be used to assemble cards or electronic devices such as mobile phones. When first clamping structure 21 is moved from the first position to the second position along the first direction, first clamping structure 21 can be away from first clamping groove 11, so that first shell 1 and second shell 2 can be disassembled and separated. Therefore, the utility model embodiment realizes the assembly and disassembly of first shell 1 and second shell 2 through first clamping structure 21 and first clamping groove 11, without setting multiple magnets, so that the structure is simple, the cost is low, the quality is light, and the portability is improved.

[0030] Further, in some embodiments, the first clamping groove 11 has an opening 111 on the side facing the second shell 2 along the axial direction, and the axial direction and the first direction are orthogonal. The first clamping structure 21 is placed in the first clamping groove 11 through the opening 111, and the opening 111 has a preset size along the first direction.

[0031] Specifically, the axial projection of the opening 111 is slightly larger than the axial projection of the first clamping structure 21, so that the first clamping structure 21 can enter the first clamping groove 11 from the opening 111, and the size of the opening 111 in the first direction is small. In this way, when the first shell 1 and the second shell 2 are assembled, the first clamping structure 21 is limited by the size of the opening 111 in the first direction, so that the first clamping structure 21 cannot automatically move in the first direction, or the amplitude of movement in the first direction is small and can be ignored, so that the first shell 1 and the second shell 2 are relatively static in the first direction without external force.

[0032] It should be noted that the first direction is orthogonal to the axial direction, and therefore, the first direction can be the length direction of the first shell 1 and the second shell 2, or the width direction of the first shell 1 and the second shell 2.

[0033] Further, in some embodiments, the first clamping groove 11 further has a bone position 112 arranged on the side of the opening 111 facing the second shell 2 in the axial direction; the first clamping structure 21 includes a protrusion 211 protruding in the first direction; when the first clamping structure 21 is in the first position, the protrusion 211 abuts the inner side of the bone position 112 to limit the movement of the second shell 2 away from the first shell 1 in the axial direction; when the first clamping structure 21 is in the second position, the protrusion 211 is separated from the bone position 112, and the first clamping structure 21 can move away from the first clamping groove 11 through the opening 111, so that the second shell 2 can move away from the first shell 1 in the axial direction.

[0034] Specifically, the first clamping groove 11 is provided with a bone position 112 on the side of the opening 111. When not assembled, the first clamping structure 21 can enter the first clamping groove 11 through the opening 111, at this time the first clamping structure 21 is in the first position. When the first clamping structure 21 is pushed from the second position to the first position, the protrusion 211 of the first clamping structure 21 abuts the inner side of the bone position 112 in the axial direction, at this time the first clamping structure 21 cannot be separated from the opening 111, so that clamping can be achieved. And specifically, the protrusion 211 and the bone position 112 can limit the movement of the second shell 2 away from the first shell 1 in the axial direction, so that the first shell 1 and the second shell 2 can be stably connected in the axial direction. In addition, when the first clamping structure 21 is pushed from the first position to the second position, at this time the protrusion 211 is no longer abutted with the bone position 112, and the protrusion 211 is located at the opening 111 in the axial direction, so that the first clamping structure 21 can be taken out from the first clamping groove 11 through the opening 111. The entire assembly and disassembly process only needs to push the first clamping structure 21 to move in the first direction, which is convenient to operate.

[0035] Further, in some specific embodiments, the first clamping structure 21 further comprises a protruding structure 212 extending along the axial direction, the protruding block 211 is arranged at one end of the protruding structure 212 close to the first shell 1 along the axial direction, and the protruding block 211 protrudes from the protruding structure 212 along the second direction. Therefore, when the first clamping structure 21 is inserted into the first clamping groove 11 through the opening 111, the protruding structure 212 is partially arranged in the first clamping groove 11 and partially arranged at the opening 111. And when the first clamping structure 21 is arranged at the first position, the protruding block 211 abuts against the inner side of the bone site 112 along the axial direction, and the protruding structure 212 abuts against the circumferential side of the bone site 112 along the first direction.

[0036] It should be noted that the first direction and the axial direction are orthogonal, and the first direction and the second direction are orthogonal, so when the first direction can be the length direction of the first shell 1 and the second shell 2 or the width direction of the first shell 1 and the second shell 2, the second direction can be the width direction of the first shell 1 and the second shell 2 or the length direction of the first shell 1 and the second shell 2.

[0037] Further, in some embodiments, along the second direction, both sides of the first shell 1 are provided with the first clamping groove 11, the first clamping groove 11 comprises a groove wall, and the groove wall of the first clamping groove 11 arranged at one side of the first shell 1 is arranged away from the groove wall of the first clamping groove 11 arranged at the other side along the second direction; the first clamping structure 21 corresponds to the first clamping groove 11 one by one, and the first clamping structure 21 abuts against the groove wall; the first direction and the second direction are orthogonal.

[0038] Specifically, the first clamping groove 11 is arranged on both sides of the first shell 1, and the first clamping groove 11 has only one groove wall in the second direction. The first clamping grooves 11 on both sides are symmetrically arranged, so that the groove walls of the first clamping grooves 11 on both sides are away from each other. For example, the second direction is the width direction, and the second direction includes the left-right direction. The groove wall of the first clamping groove 11 on the left side of the first shell 1 is located at the leftmost side, and the groove wall of the first clamping groove 11 on the right side is located at the rightmost side. Thus, when the first clamping structure 21 corresponds to abut against the groove wall, the groove wall of the first clamping groove 11 on the left side limits the first clamping structure 21 on the left side from moving to the left, and the groove wall of the first clamping groove 11 on the right side limits the first clamping structure 21 on the right side from moving to the right. Thus, the first shell 1 and the second shell 2 cannot move relative to each other in the left-right direction. Therefore, the first shell 1 and the second shell 2 can be stably connected in the second direction. In addition, the first clamping groove 11 is arranged on both sides in the axial direction, so that the first shell 1 and the second shell 2 can be balanced in force, and the connection stability can be better ensured. In addition, the first clamping groove 11 has only one groove wall, so that the material can be saved. In addition, the first clamping groove 11 can also have an opening 111 in the second direction, so that the movement of the first clamping structure 21 can be observed through the opening 111, and to some extent, the first clamping structure 21 can be facilitated to enter the first clamping groove 11.

[0039] Further, in some embodiments, the first clamping groove 11 includes two groove walls arranged opposite in the second direction, the first clamping structure 21 abuts between the two groove walls, and the first direction and the second direction are orthogonal.

[0040] Specifically, the first clamping groove 11 can be arranged on one side of the shell in the second direction. The first clamping groove 11 can have two groove walls in the second direction. Thus, the first clamping structure 21 is arranged in the first clamping groove 11, and the two groove walls and the first clamping structure 21 can realize the stable connection of the first shell 1 and the second shell 2 in the second direction.

[0041] Further, in some embodiments, the first clamping groove 11 can be arranged on both sides of the first shell 1 in the second direction, and the first clamping groove 11 can have two groove walls in the second direction. The first clamping structure 21 and the first clamping groove 11 correspond one by one, and the stable connection of the first shell 1 and the second shell 2 in the second direction can also be realized, and the connection stability can also be improved. Here, no further description is made.

[0042] Further, in some specific embodiments, along the second direction, both sides of the first shell 1 are provided with the first clamping grooves 11, and the first clamping grooves 11 on the same side are arranged at intervals, the first clamping structure 21 and the first clamping groove 11 correspond one by one, and the first direction and the second direction are orthogonal. In this way, the connection stability of the first shell 1 and the second shell 2 can be improved. In addition, the positions of the first clamping grooves 11 on both sides can correspond or not correspond, and the number can be the same or not the same.

[0043] Further, in some embodiments, the first shell 1 is also provided with a second clamping groove 12 on one side along the first direction, and the second shell 2 is provided with a second clamping structure 22 corresponding to the second clamping groove 12.

[0044] Specifically, the clamping groove and the clamping structure can also be arranged on one side of the shell along the first direction. Similarly, the second clamping structure 22 can move along the second clamping groove 12, which can serve the purpose of positioning along the first direction. During assembly, the second clamping structure 22 and the second clamping groove 12 can be positioned and connected, and then the first shell 1 or the second shell 2 is pushed along the first direction, so that the first clamping structure 21 moves from the second position to the first position, and at this time the second clamping structure 22 can also be clamped in the second clamping groove 12. By arranging the second clamping groove 12 and the second clamping structure 22, the connection stability can be further improved.

[0045] Further, in some embodiments, the second shell 2 is also provided with a second clamping groove 12 on one side along the first direction, and the first shell 1 is provided with a second clamping structure 22 corresponding to the second clamping groove 12. Similarly, the purpose of positioning along the first direction can be achieved, and the connection stability can be further improved, which will not be repeated here.

[0046] Further, in some embodiments, the protective sleeve is also provided with a boosting groove 3, and the boosting groove 3 is arranged on the outer circumferential side of the first shell 1 and the second shell 2. The boosting groove 3 is located on the other side of the first shell 1 along the first direction.

[0047] Specifically, the boosting groove 3 can be a small groove, part of which is arranged on the outer circumferential side of the first shell 1, and part of which is arranged on the outer circumferential side of the second shell 2, that is, the boosting groove 3 at least passes through the connection between the first shell 1 and the second shell 2, so that the first shell 1 and the second shell 2 can be separated from the boosting groove 3. In the actual process, the first shell 1 or the second shell 2 can be pushed to move along the first direction, and then the two can be separated through the boosting groove 3.
