[0025] Example 1

[0026] This embodiment is intended to help solve the problem of not being easy to carry when moving the speaker. Figure 1-7 A portable speaker includes a speaker body 110 and a handle 150. A notch 111 is provided on the top of the speaker body 110, an electrical connection slot 112 is provided inside the notch 111, a plug-in terminal 151 is installed at the bottom of the handle 150, the plug-in terminal 151 is engaged with the electrical connection slot 112, a first slide groove 113 is provided on the inner wall of the notch 111, a first slider 152 is installed on the side of the handle 150, the first slider 152 is slidably engaged with the first slide groove 113, a cavity 114 is provided inside the speaker body 110, a limit strip 154 ​​is installed inside the cavity 114, a limit notch 153 is provided on the side of the first slider 152, the limit strip 154 ​​is slidably engaged with the limit notch 153.

[0027] A through hole 115 is provided on the inner wall of the first slide groove 113. The through hole 115 is set as a rectangular hole. The through hole 115 connects the cavity 114 and the first slide groove 113. The limiting strip 154 ​​is divided into a longitudinal module 120 and a transverse module 121. The transverse module 121 is located inside the cavity 114. The transverse module 121 is inserted into the middle of the through hole 115, and the transverse module 121 reciprocates inside the cavity 114 and the first slide groove 113.

[0028] A sealing cover 122 is installed at the end of the longitudinal module 120, and the sealing cover 122 is fixedly connected to the longitudinal module 120. A second slider 123 is provided at the bottom of the sealing cover 122, and a second slide groove 124 is provided on the side of the audio body 110. The first slider 152 is plug-slidably connected with the second slide groove 124. A spring 143 is provided inside the cavity 114, and one end of the spring 143 is connected to the side of the longitudinal module 120, and the other end of the spring 143 is connected to the inner wall of the cavity 114.

[0029] In this embodiment, by installing a first slider 152 on the side of the handle 150 and setting a first slide groove 113 in the notch 111, the plug-in terminal 151 is aligned with the electrical connection groove 112 when engaging, and the first slider 152 slides inside the first slide groove 113, and at the same time, the sealing cover 122 is moved, and the second slider 123 at the bottom of the sealing cover 122 slides above the second slide groove 124, driving the limit strip 154 ​​at the bottom of the sealing cover 122 to move in the cavity 114 and stretch the spring 143. When the first slider 152 slides to the first slide groove 113, the second slider 123 at the bottom of the sealing cover 122 slides above the second slide groove 124, the limit strip 154 ​​at the bottom of the sealing cover 122 moves in the cavity 114 and stretches the spring 143. When the mechanical device reaches the bottom of a slide groove 113, the sealing cover 122 is loosened, the spring 143 rebounds, and the limiting strip 154 ​​is engaged in the notch. When it needs to be taken out, the sealing cover 122 is moved to pull out the limiting strip 154. The setting of the limiting strip 154 ​​and the limiting notch 153 makes it easier to disassemble and load the mechanical device during transportation, and it can be conveniently installed on site. This is especially important for large speakers, because they can reduce transportation costs by being disassembled into smaller components, and on-site installation is also more efficient.

[0030] Example 2

[0031] This embodiment is intended to help solve the wear problem of the limit strip 154 ​​after repeated use. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-7 A rotating groove 130 is provided on the inner wall of the notch 111, and the rotating groove 130 is set as a rectangular groove. A plurality of balls 131 are connected inside the rotating groove 130, and the plurality of balls 131 are closely arranged inside the rotating groove 130, and the balls 131 slide in cooperation with the rotating groove 130. A pulley 140 is slidably installed at the bottom of the cavity 114, and the other side of the pulley 140 is tightly fitted with the horizontal module 121. A rotating shaft 141 is provided in the middle of the pulley 140, and a fixing rod 142 is provided in the semi-enclosed outer side of the pulley 140. The fixing rod 142 is connected to both ends of the rotating shaft 141, and the other end of the fixing rod 142 is connected to the bottom wall of the cavity 114.

[0032] In this embodiment: by setting the ball 131 on the inner wall of the slot 111, when the limit bar 154 slides on the inner wall of the slot 111, a roller is set at the bottom of the cavity 114, and the roller is fitted with the limit bar 154, so that it can slide into the first slide groove 113 as easily as possible, extending the service life. When the limit bar 154 slides or rotates between the ball 131, the ball 131 will bear the main contact force and rolling friction, reducing the direct contact between the inner wall of the structure and the limit bar 154. This design can reduce energy loss and wear, and improve the life and performance of the mechanical structure.
