Connection structure provided by the utility model as shown in Figure 1, including shell 1, fastener spring piece 2 and inner casing 3, shell 1
The first groove 11 is offered on inner wall；Fastener spring piece 2 is fixed in the second groove 31 and protrudes from the outer surface of inner casing 3；Inner casing 3
Outer wall on the second groove 31 is set, fastener spring piece 2 is clamped with the first groove 11, realizes the connection of shell 1 and inner casing 3.
As shown in Fig. 2, the shape of shell 1 is circular tube shaped, multiple first grooves have been uniformly arranged on the inner wall of shell 1
11, it is preferable that the first groove 11 is square groove in the present embodiment, and square groove shape is commonplace, and the scope of application is wider, outside
Circumferentially extended 3rd groove 12 is provided with the inner wall of shell 1, the 3rd groove 12 is located at the first groove 11 away from 3 side of inner casing
Circumference on, and connected with the first groove 11, the first groove 11 extends to the edge of shell 1.
As shown in figure 3, fastener spring piece 2 includes fixed part 23, connecting portion 22 and card-tight part 21.It is provided with fixed part 23
One through hole 231, fixed part 23 are connected by screw with inner casing 3；Connecting portion 22 can be divided into three regions, be tablet area respectively
221st, the 23 place plane of fixed part of arch area 222 and cambered surface area 223, tablet area 221 and fastener spring piece 2 is to be vertically connected on one
Rise, 222 the right and left of arch area is connected to tablet area 221 and cambered surface area 223, and the setting of arch area 222, which is advantageous in that, ensure that
The elasticity of fastener spring piece 2 and there is certain rigidity, make between shell 1 and inner casing 3 by outside elastic force and clamping tightly
Together；The cambered surface projection in cambered surface area 223 is close to the direction in tablet area 221, so sets advantage to be that shell 1 exists
During being clamped close to inner casing 3, the inner wall of shell 1 can with 223 sliding contact of cambered surface area of 2 connecting portion 22 of fastener spring piece,
Cambered surface such as cambered surface area 223 is changed into plane, then increases the resistance that shell 1 is moved towards inner casing 3, and cambered surface can then greatly reduce
The resistance of this part, allows clamping process more smooth, makes assembling process more easily convenient；Card-tight part 21 includes one
Bent area 211, the bent area 211 away from tablet area 221 direction protrusion set, be caught in the first groove 11, realize inner casing 3 with
Shell 1 connects.
As shown in figure 4, the shape of inner casing 3 is circular tube shaped, multiple and the first groove 11 is evenly arranged with 3 outer wall of inner casing
The second corresponding and equal quantity groove 31, it is preferable that the lateral cross section of the second groove 31 takes the shape of the letter U, the length of the second groove 31
It is consistent with the axial direction of inner casing 3 to spend direction, a threaded hole 33 has been opened up in the second groove 31, buckle bullet is passed through with screw
Through hole 231 on the fixed part 23 of piece 2 is fastenedly connected with the threaded hole 33 in the second groove 31, is set against the second groove 31
It is equipped with a protrusion 32, protrusion 32 is L-shaped, and including orthogonal first protrusion, 321 and second protrusion 322, first
Protrusion 321 is the long side of L-shaped, its length direction is circumferential consistent with inner casing 3, and the second protrusion 322 is the short side of L-shaped, and
Its length direction is axial consistent with inner casing 3.Second protrusion 322 is set close to the fastener spring piece 2, the second protrusion 322
It is equal to the length of first groove 11 circumferentially with the total length of fastener spring piece 2 circumferentially, when inner casing 3 and the connection of shell 1,
2 and second protrusion 322 of fastener spring piece is caught in the first groove 11 at the same time.According to different connection needs, the second protrusion 322
It can be less than the length of the first groove 11 vertically with the total length of fastener spring piece 2 circumferentially.
When inner casing 3 and shell 1 are connected with each other, first, close to each other between shell 1 and inner casing 3, the cambered surface of fastener spring piece 2
Area 223 and bent area 211 are pushed by the inner wall of shell 1, and fastener spring piece 2 is pressed into the second groove 31, and protrusion 32 is via first
Groove 11 enters in shell 1 so that the first protrusion 321 is caught in the 3rd groove 12, and the second protrusion 322 is recessed still in first
In groove 11, along protrusion 32 towards fastener spring piece 2 direction rotation case 1, at this time fastener spring piece 2 gradually stretch into the first groove 11
It is interior, realize the limitation to the 3 circumferentially opposed movement of shell 1 and inner casing.Such as rotational shell 1 again, then it is opposite shell 1 will not to occur again
The rotation of inner casing 3, while the first protrusion 321 and the 3rd groove 12 are connected together, then can not be along shell 1 and inner casing 3
Axial direction the two is separated.Since the synchronization of fastener spring piece 2 and protrusion 32 is spacing, the week of shell 1 and inner casing 3 is just realized
To the connection with axial direction.
After realizing that shell 1 is connected with each other with inner casing 3, there are gap, Ke Yitong between 3 edge of 1 edge of shell and inner casing
Cross specific instrument to be deep into gap, withstand the Access Division 21 of fastener spring piece 2 and it is moved towards tablet area 221, will be curved
Folding area 211 is ejected outside the first groove 11, rotational shell 1 at this time, until the first groove 11 and the second protrusion 322 abut against, edge
The axial direction of inner casing 3, shell 1 is extracted, it is achieved thereby that the separation of inner casing 3 and shell 1.
Present embodiment also proposes a kind of sound equipment, including above-mentioned connection structure, and installation and removal are convenient, simple in structure,
Fastener spring piece 2 is installed on the inside of loudspeaker casing, and unnecessary influence will not be caused on sound equipment appearance.
Embodiment of above is to elaborate the basic principle and characteristic of the utility model, and the utility model is from above-mentioned reality
The mode of applying limits, and on the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes,
These changes and modifications are both fallen within claimed the scope of the utility model.The utility model requires protection scope is by appended
