A support portion 312 of the knob member 31 is provided with a plurality of second slots 3121, which are arranged around the rotating shaft 311 and spaced from the outer wall of the rotating shaft 311.

[0089] In one embodiment, if Figure 3 and Fig.10 As shown, the elastic connecting member 33 can be selected as one, and the elastic connecting member 33 has a hollow cavity 331, and the rotating cylinder 22 is located in the hollow cavity 331. It can be understood that the elastic connecting member 33 is sleeved on the outer wall of the rotating cylinder 22.

[0090] Optionally, the cross-sectional area at both ends of the elastic connector 33 is larger than the cross-sectional area at the center of the elastic connector 33. In this way, the two ends of the elastic connector 33 can be conveniently clamped in the first clamping slot 23 and the second clamping slot 3121.

[0091] In this embodiment, when the rotating shaft 311 of the knob member 31 is inserted into the rotating cavity 221 of the rotating cylinder 22, the elastic connecting member 33 is stretched, and under the action of the spring stretching force of the elastic connecting member 33, the rotating shaft 311 of the knob member 31 is inserted into the rotating cavity 221 of the rotating cylinder 22, and the clamping platform 3111 of the rotating shaft 311 slides into the buckle 224, so that it cannot be disengaged backwards under the limiting action of the buckle 224. At the same time, the supporting portion 312 of the knob member 31 abuts against the end surface of the rotating cylinder 22 to achieve the limiting effect.

[0092] It can be understood that, in the absence of external force, there is a certain distance between the latch 224 and the latching platform 3111, which can prevent the knob 31 from having a large friction when rotating, and prevent the rotating shaft 311 of the knob 31 from separating from the rotating cavity 221 of the rotating cylinder 22 when an external force is applied.

[0093] In another embodiment, the elastic connector 33 includes a plurality of elastic connectors 33, and the plurality of elastic connectors 33 are arranged around the rotating cylinder 22. It can be understood that the plurality of elastic connectors 33 are arranged at intervals and around the rotating cylinder 22. In this embodiment, the second housing 2 and the support portion 312 are respectively provided with a first slot 23 and a second slot 3121 corresponding to each elastic connector 33.

[0094] Of course, in order to facilitate the disassembly and assembly of the elastic connector 33 and ensure that the elastic connector 33 does not affect the rotation of the knob 31 relative to the second shell 2, any method is acceptable as long as the elastic connector 33 can be connected to the second shell 2 and the support portion 312, and no limitation is made here.

[0095] In one embodiment, the rotating cylinder 22 is provided with a notch 223 connected to the rotating chamber 221 and a latch 224 disposed in the notch 223. The outer wall of the rotating shaft 311 is provided with a latching platform 3111. When the rotating shaft 311 moves along the axial direction of the rotating chamber 221 and disengages, the latch 224 is latched with the latching platform 3111.

[0096] In this embodiment, if Figure 3 , Figure 4 , Figure 6 As shown, by setting a notch 223 on the rotating cylinder 22 of the second shell 2, setting a snap member 224 in the notch 223, and setting a snap-in platform 3111 on the rotating shaft 311 of the knob member 31, when the rotating shaft 311 is pushed to move along the axial direction of the rotating cavity 221 and disengage under the action of external force, the snap-in platform 3111 can be snapped by the snap-in platform 3111, thereby preventing the rotating shaft 311 of the knob member 31 from disengaging from the rotating cavity 221 of the rotating cylinder 22.

[0097] In one embodiment, if Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a groove 3112 is provided on one end surface of the rotating shaft 311 facing away from the supporting portion 312. It can be understood that by providing the groove 3112 on the rotating shaft 311 of the knob member 31, it is convenient for the user to drive the knob member 31 to rotate through the groove 3112 through an external component, thereby improving convenience.

[0098] Optionally, the support portion 312 of the knob member 31 abuts against an end surface of the rotating cylinder 22 away from the first surface of the second shell 2 .

[0099] In one embodiment, a limiting groove 3122 is provided on one side of the support portion 312 of the knob member 31 facing away from the rotation shaft 311, and the elastic portion 323 is limited in the limiting groove 3122. It can be understood that the limiting groove 3122 can be used to further limit the elastic member 32, so that the elastic member 32 rotates relative to the second housing 2 as the knob member 31 rotates.

[0100] In one embodiment, the elastic portion 323 includes a first straight section 3231, a vertical section 3232 and a second straight section 3233 that are connected to each other. The first straight section 3231 is connected to the mounting portion 322 and abuts against a side of the support portion 312 that is away from the rotation axis 311 for limiting positioning. The second straight section 3233 is connected to the locking portion 321 at one end away from the vertical section 3232 and abuts against a surface of the second shell 2. The first straight section 3231 and the second straight section 3233 are located in different planes.

[0101] In this embodiment, if Figure 1 , Figure 3 , Fig. 9 As shown, the first straight section 3231 and the second straight section 3233 of the elastic portion 323 are optionally arranged in parallel. The first straight section 3231 is connected to the mounting portion 322, and the first straight section 3231 and the mounting portion 322 are located in the same plane, and both are abutted and limited with the side of the support portion 312 facing away from the rotation axis 311. The vertical section 3232 can make the first straight section 3231 and the second straight section 3233 located in different planes, so that the second straight section 3233 is convenient to abut against the first surface of the second shell 2.

[0102] Optionally, the locking portion 321 is connected to an end of the second straight section 3233 away from the vertical section 3232. In this embodiment, the elastic portion 323 extends from the mounting portion 322 toward the edge of the second housing 2. In this embodiment, the locking portion 321 and the second straight section 3233 are optionally located in the same plane.

[0103] In one embodiment, the locking portion 321 includes a first arc segment 3211 and a second arc segment 3212 connected to each other, the first arc segment 3211 is connected to the elastic portion 323, and the second arc segment 3212 forms a free end 3213 at one end away from the first arc segment 3211; in the assembled state, the projection of the free end 3213 on the second shell 2 is located within the projection range of the second shell 2, and the projection of part of the second arc segment 3212 on the second shell 2 is located outside the projection range of the second shell 2; in the disassembled state, the projection of the second arc segment 3212 on the second shell 2 is all located within the projection range of the second shell 2.

[0104] In this embodiment, if Figure 1 , Figure 3 , Figure 4 and Fig. 9As shown, by setting the locking portion 321 as an arc structure, the locking portion 321 is set as a first arc segment 3211 and a second arc segment 3212 connected to each other, so that the arc shape of the locking portion 321 can be used to conveniently limit the locking portion 321 in the shrinking slot 21 and the locking slot 12. It can be understood that by forming a free end 3213 at one end of the second arc segment 3212 away from the first arc segment 3211, the free end 3213 can be used to guide the locking portion 321 when it is limited in the shrinking slot 21.

[0105] It can be understood that when the elastic member 32 is in a normal state, that is, when it is not contracted in the contraction slot 21, the distance from the free end 3213 to the rotation center of the knob member 31 is smaller than the distance from at least part of the second arc segment 3212 to the rotation center of the knob member 31. In this embodiment, the distance from the free end 3213 to the rotation center of the knob member 31 is smaller than the distance from the edge of the second housing 2 to the rotation center of the knob member 31, and the distance from at least part of the second arc segment 3212 to the rotation center of the knob member 31 is greater than the distance from the edge of the second housing 2 to the rotation center of the knob member 31.

[0106] Optionally, when the housing structure 100 is in an assembled state, the projection of the free end 3213 on the second housing 2 is within the projection range of the second housing 2, and the projection of part of the second arc segment 3212 on the second housing 2 is outside the projection range of the second housing 2; when the housing structure 100 is in a disassembled state, the projection of the second arc segment 3212 on the second housing 2 is all within the projection range of the second housing 2. In this way, the second housing 2 can be locked with the first housing 1 through the locking portion 321 of the locking assembly 3.

[0107] In this embodiment, the second arc segment 3212 is a convex arc with the center located on the side of the second arc segment 3212 facing the mounting portion 322 .

[0108] In one embodiment, the second housing 2 is further provided with a limiting protrusion 24 spaced apart from the shrinking slot 21 ; wherein when the knob member 31 drives the elastic member 32 to rotate relative to the second housing 2 , the locking portion 321 moves between the limiting protrusion 24 and the shrinking slot 21 .

[0109] In this embodiment, if Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, by providing a limiting protrusion 24 on the first surface of the second housing 2, the limiting protrusion 24 serves as a stop and phase effect on the rotation of the elastic member 32 relative to the second housing 2, thereby avoiding rotation transition.

[0110] Optionally, the shrinking slot 21 and the limiting protrusion 24 are disposed adjacent to the edge of the second housing 2. In this embodiment, the limiting protrusion 24 includes a plurality of limiting protrusions, and each limiting protrusion 24 corresponds to a shrinking slot 21.

[0111] In the present application, the first shell 1 and the second shell 2 of the shell structure 100 are quickly fixed or quickly disassembled through the locking assembly 3. When assembling or disassembling the first shell 1 and the second shell 2, only one point needs to be controlled, that is, the knob part 31 of the locking assembly 3. There are no multiple fixing positions that need to be controlled. Only by rotating the knob part 31, quick fixing or quick disassembly can be achieved, which is convenient and quick, and the integrity of the appearance is maintained to a certain extent.

[0112] It is understandable that the shell structure 100 of the present application does not significantly change the overall appearance of the product, and is easy to operate, without complicated operating steps, without large operating force, and convenient for assembly and disassembly. It should be noted that the shell structure 100 can quickly assemble the common shell and shell of the product together, and can also be quickly disassembled.

[0113] In this embodiment, the elastic member 32 of the locking assembly 3 is fixed to the knob member 31 by bolts 34 or screws, and the knob member 31 is tightened together with the second shell 2 under the action of the spring tension of the elastic connecting member 33 to form a shell assembly. The shell assembly drives the rotation of the elastic member 32 by the rotation of the knob member 31, and then the locking portion 321 at the end of the elastic member 32 is screwed into the locking slot 12 of the first shell 1 for fixing. It can be understood that by rotating the knob member 31 to quickly screw the locking portion 321 at the end of the elastic member 32 into or out of the locking slot 12 of the first shell 1 and the contraction slot 21 of the second shell 2, the second shell 2 can be quickly fixed or removed.

[0114] It can be understood that before installing the second shell 2 of the shell structure 100, use a flat-head tool, such as a flat-head screwdriver, to insert it into the groove 3112 on the outer surface of the knob member 31, rotate the knob member 31, and then the elastic member 32 rotates with the knob member 31. The end locking portion 321 of the elastic member 32 is arc-shaped and has a guiding function. When rotating, the locking portion 321 of the elastic member 32 can be turned into the shrinkage slot 21 of the second shell 2, and the locking portion 321 of the elastic member 32 is retracted into the shrinkage slot 21.

[0115] When the second shell 2 of the shell structure 100 is installed on the first shell 1, the shell assembly formed by the assembled second shell 2 and the locking assembly 3 is placed in the corresponding mounting hole 11 position of the first shell 1, and the knob member 31 is rotated in the opposite direction to make the locking portion 321 of the elastic member 32 rotate out from the contraction slot 21 of the second shell 2. At this time, the locking portion 321 of the elastic member 32 is released, and the knob member 31 is continued to be rotated, and the locking portion 321 is screwed into the locking slot 12 of the first shell 1, so that the second shell 2 is fixed together with the first shell 1. It can be understood that the limiting protrusion 24 of the second shell 2 has a retaining wall effect to prevent the locking portion 321 of the elastic member 32 from excessively rotating in this process and rotating out of the locking slot 12 of the first shell 1, thereby playing a limiting role.

[0116] When the second housing 2 of the housing structure 100 is removed from the first housing 1, the knob 31 is rotated in the opposite direction again to rotate the locking portion 321 of the elastic member 32 out of the locking slot 12 of the first housing 1. The knob 31 is then rotated into the shrinking slot 21 of the second housing 2 to reach the state before installation, and the second housing 2 can be removed.

[0117] It should be noted that after the knob member 31, the second housing 2, etc. are assembled into an assembly as described above, the rotation of the knob member 31 drives the rotation of the elastic member 32, and then the locking portion 321 at the end of the elastic member 32 is screwed into or out of the contraction slot 21 of the second housing 2 and the locking slot 12 of the first housing 1, so as to perform fixing and disassembly. Since the elastic member 32 has multiple end locking portions 321, the second housing 2 and the first housing 1 can be fixed at multiple locations during fixing to meet the fixing strength, and the second housing 2 and the first housing 1 are fixed by the engagement of the elastic member 32. In this way, by controlling the knob member 31, and then controlling the internal engagement structure, the rapidity of fixing and disassembly is achieved without affecting the fixing strength.

[0118] It can be understood that the second shell 1 and the first shell 1 are not limited to a circular fit. Since it is the internal structure of the second shell 2 that rotates during rotation, whether the second shell 2 itself rotates does not affect the assembly and disassembly process, so the shapes of the second shell 2 and the first shell 1 can be other regular or irregular shapes.

[0119] Compared with existing products, the shell structure 100 of the present application is that the fixed assembly and disassembly of the second shell 2 and the first shell 1 can be achieved by controlling only one knob member 31, and has the advantages of rapidity and simple appearance. This structure is convenient for users to operate, quick, and not prone to misoperation.
