Referring to fig. 2, 5 to 8, fig. 7 is a side view of the fixing member of the embodiment of the housing assembly of the present application, and fig. 8 is a schematic view of a back structure of the fixing member of the embodiment of the housing assembly of the present application, specifically, the second position-limiting portion 320 includes a connecting member 321 and a position-limiting post 322 fixedly connected to the connecting member 321. The connecting element 321 is fixedly connected to the fixing base 310 and located on a side of the fixing base 310 close to the receiving cavity 210. The limiting post 322 extends from the connecting member 321 to a direction away from the connecting member 321. When the second position-limiting portion 320 rotates in the first section of hole 221, the position-limiting post 322 can rotate around the connecting piece 321 in the first section of hole 221; when the second position-limiting portion 320 and the second section of hole 222 are dislocated, the position-limiting post 322 abuts against the housing 100 in the first section of hole 221, the fixing seat 310 abuts against the housing 100 on the back of the housing 100, and the position-limiting post 322 and the fixing seat 310 are mutually matched to mount the fixing member 300 on the through hole 220 of the housing 100.

When the position-limiting post 322 rotates to a certain angle in the first section of hole 221, the position-limiting post 322 and the first position-limiting portion 223 are abutted against each other, so that the second position-limiting portion 320 is prevented from further rotating, and the position-limiting post 322 stops rotating.

Optionally, the first limiting portion 223 may be a limiting table surrounding the edge of the second section of hole 222, the limiting table has a certain slope, the limiting column 322 corresponds to a slope surface with a slope, and when the limiting column 322 rotates to a certain angle in the first section of hole 221, the slope surface of the first limiting portion 223 and the slope surface of the limiting column 322 abut against each other and are attached to each other, so as to prevent further rotation of the second limiting portion 320.

Optionally, the first position-limiting portion 223 and the second position-limiting portion 320 may be made of a material with a large friction coefficient, so that the static friction of the slope surface of the first position-limiting portion 223 and the slope surface of the position-limiting post 322 is large, the first position-limiting portion 223 and the second position-limiting portion 320 are in interference fit, the fixing member 300 is more stably fixed to the through hole 220 of the housing 100, and a user can feel a certain damping feeling when rotating the fixing member 300.

The hooking component 400 shown in fig. 2 can penetrate through the back of the fixing component 300 (the side exposed at the back of the casing 100) into the accommodating cavity 210, and is fixed in the rope fixing position.

In this embodiment, the second position-limiting portion 320 abuts against the housing 100 in the first section of the hole 221, so that the fixing member 300 cannot be separated from the housing 100 at the second section of the hole 222, and the fixing seat 310 abuts against the housing 100 at the back of the housing 100, so that the fixing member 300 cannot be separated from the housing 100 at the second section of the hole 222. And the first position-limiting portion 223 abuts against the second position-limiting portion 320 in the first-stage hole 221, so that the second position-limiting portion 320 cannot be loosened in the first-stage hole 221. Meanwhile, the back surface of the fixing member 300 is not provided with any element, so that the housing assembly of the present application may be more integrated in appearance.

Therefore, in the embodiment, when the user fixes the fixing member 300 to the through hole 220 of the housing 100, the second position-limiting portion 320 of the fixing member 300 is inserted into the second section of the hole 222 until the fixing seat 310 abuts against the housing, then the fixing member 300 is rotated to make the second position-limiting portion 320 and the second through hole dislocate, the second position-limiting portion 320 abuts against the housing 100 in the first section of the hole 221, and finally the fixing member 300 is rotated until the first position-limiting portion 223 and the second position-limiting portion 320 abut against each other, so that the fixing member 300 is installed. If the fixing element 300 is to be detached from the housing 100, the fixing element 300 is only required to rotate in the opposite direction during installation, so that the first position-limiting portion 223 and the second position-limiting portion 320 are separated from each other until the second position-limiting portion 320 and the second section of hole 222 are in the same order, and then the second position-limiting portion 320 passes through the second section of hole 222, and the fixing element 300 is detached from the back of the housing 100.

Meanwhile, the hanging rope 410 may be divided into two sections, one section is connected to the detaching member 420 and the fixing member 300, the other section is connected to the detaching member and suspended, and the suspended portion is used for connecting to an external object.

In the present embodiment, since the first rotation portion 360 is exposed to the back surface of the housing assembly 11, the first rotation portion 360 can also serve as a decoration. The grooves on the first rotary part 360 can form logo, text, texture or other patterns with certain artistic aesthetic feeling, so as to further improve the aesthetic property of the housing assembly 11. As shown in fig. 10, in this embodiment, the rope hanging via hole 340 is disposed on a side surface of the fixing base 310, and the rope hanging via hole 340 does not shield the first rotation position 360 on the back surface of the fixing base 310.
