[0025] Among them, an inverted convex groove 103 is provided on the lower surface of the upper ring plate 1 and at a position corresponding to the extension column 303, and a slider 306 is slidably connected to the upper end of the inner part of the convex groove 103, and the bottom of the slider 306 is fixedly connected to the top of the extension column 303, and a first spring 307 is fixedly connected between the inner end of the slider 306 and the inner wall of the convex groove 103; since the fixed column 301 and the extension column 303 are inclined, when the extension column 303 moves in the extension groove 302, it can drive the slider 306 to slide in the convex groove 103, thereby facilitating the adjustment of the upper ring plate 1 and the lower ring plate 2, and the first spring 307 can always squeeze the slider 306.

[0026] In addition, the limiting assembly includes a cavity 5, which is arranged in the middle of one end of the extension column 303 close to the extension groove 302, and a movable plate 501 is slidably connected inside the cavity 5, and a third spring 502 is fixedly connected between one end of the movable plate 501 and the inner wall of the cavity 5, and the other end of the movable plate 501 is rotatably connected to a pull rod 503 through a bearing, and an annular plate 504 is sleeved in the middle of the pull rod 503; by pulling the pull rod 503, the movable plate 501 can be driven to slide in the cavity 5 and stretch the third spring 502, and at the same time, the pull rod 503 can drive the annular plate 504 to move outward, and when the pull rod 503 is rotated, the annular plate 504 rotates accordingly.

[0027] In addition, a guide hole 304 slidably connected to the pull rod 503 is provided in the middle of the outer side of the fixed column 301, and a plurality of equally spaced limit grooves 305 are provided on the outer side of the guide hole 304. The contour lines relative to the limit grooves 305 are elliptical, and the long semi-axis of the contour lines relative to the limit grooves 305 are in a straight line with the center line of the guide hole 304; the movement of the extension column 303 can drive the pull rod 503 to move in the guide hole 304.

[0028] In addition, one end of the pull rod 503 away from the movable plate 501 passes through the inner wall of the cavity 5 and the guide hole 304 in sequence and extends to the outside. The diameter of the annular plate 504 is larger than the diameter of the guide hole 304. The annular plate 504 is slidably connected in the limiting groove 305. The annular plate 504 is elliptical. One end of the pull rod 503 is located outside to facilitate pulling the pull rod 503. The annular plate 504 is elliptical so that when the pull rod 503 is rotated, the long semi-axis of the annular plate 504 can contact the outer surface of the fixed column 301.

[0029] In addition, a clamping assembly 4 is provided in the middle of the upper ring plate 1 and between the adjacent connecting assemblies 3. The clamping assembly 4 includes a rectangular hole 101. The rectangular hole 101 is provided in the middle of the upper ring plate 1. The inner walls on both sides of the rectangular hole 101 are provided with guide grooves 102. An L-shaped plate 401 is slidably connected inside the rectangular hole 101. Guide blocks 402 are fixedly connected on both sides of the L-shaped plate 401. One end of the guide block 402 away from the L-shaped plate 401 is slidably connected to the inside of the guide groove 102. The horizontal end of the L-shaped plate 401 is located below the upper ring plate 1, and the top of the L-shaped plate 401 is located above the upper ring plate 1. A second spring 403 is fixedly connected between the side of the L-shaped plate 401 away from its horizontal end and the inner wall of the rectangular hole 101; under the action of the second spring 403, the L-shaped plate 401 can always be moved closer to the outside, and at the same time, the chassis mounting plate for the column between the horizontal end of the L-shaped plate 401 and the upper ring plate 1 is not shown, so that the speaker frame can be quickly installed and removed from the chassis.

[0030] Working principle: When in use, when it is necessary to adjust the height of the cover frame, the pull rod 503 can be pulled outward first, and the pull rod 503 can drive the movable plate 501 to slide in the cavity 5 and stretch the third spring 502. At the same time, the pull rod 503 can drive the annular plate 504 to move outward. When the annular plate 504 is separated from the limiting groove 305, the pull rod 503 is rotated, and the annular plate 504 rotates accordingly, so that the long semi-axis of the annular plate 504 contacts the outer side of the fixed column 301, and then the pull rod 503 is released. The three springs 502 can reset the annular plate 504 to the outer wall of the fixed column 301. When the four annular plates 504 are adjusted as above, the upper annular plate 1 and the lower annular plate 2 can be pulled or pressed to make the extension column 303 slide in the extension groove 302. At the same time, the pull rod 503 slides in the guide hole 304, and the annular plate 504 can slide with the outer surface of the fixed column 301, so that the upper annular plate 1 and the lower annular plate 2 can move away from and approach each other. At the same time, the extension column 303 can drive the slider 306 to move in the convex groove 302. The first spring 307 is compressed or released by sliding in the groove 103. When the pull rod 503 is adjusted to a suitable position, the annular plate 504 is aligned with the limiting groove 305 and the pull rod 503 is released. Under the action of the third spring 502, the annular plate 504 enters the limiting groove 305, so that the position of the extension column 303 is fixed. When the speaker frame is installed in the chassis, the bottom end of the L-shaped plate 401 with the inclined surface is aligned with the chassis installation hole and the upper ring plate 1 is pressed. Under the action of force, the chassis can push the inclined surface on the L-shaped plate 401 and make the L-shaped plate 401 move inward. At the same time, the L-shaped plate 401 drives the guide block 402 thereon to slide in the guide groove 102 and compress the second spring 403. When the installation position is aligned with the L-shaped plate 401 and the upper ring plate 1, the L-shaped plate 401 can be reset under the action of the second spring 403, so that the horizontal end of the L-shaped plate 401 and the upper ring plate 1 can be snap-fitted with the chassis installation port, completing the installation of the speaker frame and the chassis.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
