[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model drives the connecting plate to move toward the bottom by pressing the pressing block toward the bottom, and the connecting plate drives the pushing rod and the limiting block to move toward the bottom by moving toward the bottom. The limiting block moves toward the bottom and contacts the inner side of the card block, so that the card block is in a vertical state. Then the installation sleeve can be pulled toward the top to drive the sliding sleeve and the pushing rod to move toward the top. Since the connecting plate and the pressing block are always subjected to the elastic force of the spring, the pushing rod and the card block will be separated. Since the connecting block is always subjected to the tension of the tension spring, the card block will rotate around the shaft pin as the center, so that the top of the card block will move outward to enter the inside of the tightening groove, so that the sliding sleeve can be limited when it moves to any height, thereby achieving the advantage of hiding the pull rod of the bass speaker.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, the utility model provides a bass speaker with a hidden pull rod structure, including a bass speaker body 1, a placement groove 2 is opened on the top of the bass speaker body 1, both sides of the inner wall of the placement groove 2 are fixedly connected with a placement sleeve 3, the inside of the placement sleeve 3 is slidably connected with a pulling component 4 for pulling the bass speaker body 1, both sides of the bass speaker body 1 are opened with pulling holes, both sides of the placement sleeve 3 are opened with tightening grooves 6, and the number of the tightening grooves 6 is several.

[0024] refer to Figure 1-4 As shown, the pulling assembly 4 includes a sliding sleeve 41, which is located inside the placement sleeve 3 and is slidably connected to the placement sleeve 3. Blocks 42 are provided on both sides of the inner wall of the sliding sleeve 41. The front and rear sides of the block 42 are rotatably connected to the inner wall of the sliding sleeve 41 through an axle pin. A push rod 43 is slidably connected inside the sliding sleeve 41. The top of the push rod 43 penetrates through the top of the sliding sleeve 41 and is slidably connected to the sliding sleeve 41, and the bottom of the push rod 43 contacts the inner side of the block 42.

[0025] As a technical optimization solution of the utility model, through the mutual cooperation of the sliding sleeve 41, the block 42 and the pushing rod 43, when the pushing rod 43 is pulled toward the top, it will be separated from the block 42, and then the sliding sleeve 41 can be pulled toward the top. When the sliding sleeve 41 rises to a suitable height, the bass speaker body 1 can be conveniently pulled.

[0026] refer to Figure 1-4 As shown, both sides of the push rod 43 are fixedly connected to the limiting blocks 44 , and the outer sides of the limiting blocks 44 are in contact with the inner wall of the sliding sleeve 41 and are slidably connected to the sliding sleeve 41 .

[0027] As a technical optimization solution of the utility model, by setting a limit block 44, the push rod 43 can be limited to prevent the push rod 43 from shaking when moving, and also prevent the push rod 43 from contacting the inner side of the block 42.

[0028] refer to Figure 1-4 As shown, a connecting block 45 is fixedly connected to the bottom of the clamping block 42 , a tension spring 46 is provided at the bottom of the inner wall of the sliding sleeve 41 , and both ends of the tension spring 46 are fixedly connected to the inner side of the clamping block 42 .

[0029] As a technical optimization solution of the utility model, through the mutual cooperation of the connecting block 45 and the tension spring 46, the connecting block 45 can always bear the tension of the tension spring 46, so that the clamping block 42 can rotate around the axle pin, so that the top of the clamping block 42 can move outward to enter the inside of the locking groove 6, so as to limit the sliding sleeve 41 when it moves to any height.

[0030] refer to Figure 1-4 As shown, a mounting sleeve 47 is provided on the top of the bass speaker body 1, the top of the push rod 43 penetrates into the interior of the mounting sleeve 47, a connecting plate 48 is provided inside the mounting sleeve 47, and the top of the connecting plate 48 contacts the top of the inner wall of the mounting sleeve 47.

[0031] As a technical optimization scheme of the utility model, through the mutual cooperation of the mounting sleeve 47 and the connecting plate 48, when the connecting plate 48 is pressed toward the bottom, the push rod 43 can be driven to move toward the bottom, and the push rod 43 moves toward the bottom to make it contact with the inner side of the block 42. When the block 42 and the push rod 43 are in contact, they will be in a vertical state, and then the mounting sleeve 47 can be pulled toward the top to move, and the movement of the mounting sleeve 47 drives the sliding sleeve 41 and the push rod 43 to move toward the top, so that the bass speaker body 1 can be easily pulled.

[0032] refer to Figure 1-4 As shown, a spring 49 is fixedly connected to the bottom of the inner wall of the placement sleeve 3 , and there are two springs 49 . The top of the spring 49 is fixedly connected to the bottom of the connecting plate 48 .

[0033] As a technical optimization solution of the utility model, by providing the spring 49 , the connecting plate 48 can always bear the elastic force of the spring 49 , so that when the user releases the connecting plate 48 , the connecting plate 48 will automatically reset due to the elastic force of the spring 49 .

[0034] refer to Figure 1-4 As shown, the bottom of the connecting plate 48 is fixedly connected to the top of the push rod 43 , and the top of the connecting plate 48 is fixedly connected to a pressing block 410 , and the top of the pressing block 410 passes through the top of the mounting sleeve 47 .

[0035] As a technical optimization solution of the utility model, by providing a pressing block 410, when the pressing block 410 is pressed toward the bottom, the connecting plate 48 can be driven to move toward the bottom, so that the connecting plate 48 can be pressed conveniently.

[0036] The working principle and use process of the utility model are as follows: when the user needs to move the bass speaker body 1 during use, the user first presses the pressing block 410 toward the bottom to drive the connecting plate 48 to move toward the bottom, and the connecting plate 48 moves toward the bottom to drive the pushing rod 43 and the limiting block 44 to move toward the bottom, and the limiting block 44 moves toward the bottom to contact the inner side of the block 42, so that the block 42 is in a vertical state, and then the installation sleeve 47 can be pulled toward the top to drive the sliding sleeve 41 and the pushing rod 43 to move toward the top. When the sliding sleeve 41 moves to a suitable height, the pressing block 410 can be released at this time. The connecting plate 48 and the pressing block 410 are constantly subjected to the elastic force of the spring 49, which will cause the push rod 43 and the block 42 to disengage. Since the connecting block 45 is constantly subjected to the pulling force of the tension spring 46, the block 42 will rotate around the axle pin, so that the top of the block 42 will move outward to enter the inside of the tightening groove 6, so that the sliding sleeve 41 can be limited when it moves to any height. Finally, the installation sleeve 47 can be pulled to drive the bass speaker body 1 to move. When the bass speaker body 1 moves to a suitable position, the above reverse steps can be repeated to reset the installation sleeve 47.

[0037] To sum up: the bass speaker with a hidden pull rod structure solves the problem that the pull rod of the bass speaker cannot be hidden during use, resulting in the bass speaker being not beautiful enough, and the bass speaker needs to be held in the arms or carried by the user when moving it, which will cause inconvenience when moving the bass speaker.
