All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The embodiment, as shown in fig. 1 and fig. 2, provides a ceiling type sound box 1, which comprises a sound box 1, wherein one end of the sound box 1 is provided with an expansion part along the radial direction, a loudspeaker cover is embedded in the surface wall of the expansion part, the sound box structure refers to a Chinese patent of the ceiling type sound box with the publication number of CN215010585U, the name is a ceiling type sound box convenient to install, the loudspeaker cover is arranged at the bottom of a sound box main body, the loudspeaker cover is in a detachable structural design, a loudspeaker is arranged in the sound box main body and positioned at the position of the loudspeaker cover, and a control button is arranged at the center of the loudspeaker cover. When using the ceiling type stereo set of being convenient for installation, at first be connected with corresponding circular telegram wire with the stereo set main part, realize supplying power, the stereo set main part adopts bluetooth or high definition line to connect playback devices for sound broadcast.
The sound box further comprises a fastening piece, the fastening piece comprises a fastening ring 3 of an annular structure, the fastening ring 3 is in threaded sleeve connection with the outer wall of the other end of the sound box 1, and a plurality of expansion pieces 31 are arranged at one end, far away from the expansion part, of the fastening ring 3. It should be noted that the expansion piece 31 is required to be provided along the tangential direction of the outer wall of the fastening ring 3, and the expansion piece 31 is required to be bent to form a bent portion toward the side near the center of the fastening ring 3. The plurality of expansion pieces 31 form an expansion part, as shown in fig. 1 and 3, the expansion pieces 31 are not less than two, preferably two, to form a rectangular structure, and the two expansion pieces 31 are opposite to each other against the inner wall of the pre-installed slot, so as to limit the rotation of the fastening ring 3 on the inner wall of the pre-installed slot on the building ceiling.
The fastening ring 3 is directly plugged into a pre-opened slot hole in a building ceiling, then the sound 1 is in threaded connection with the fastening ring 3, the distance between the side wall of the bending part and the center of the fastening ring 3 is smaller than the radius of the fastening ring 3, as shown in fig. 4, the radial length between the side wall of the bending part and the inner wall of the fastening ring 3 is T, that is, when the end part of the sound 1 is inserted into the fastening ring 3, the end part of the sound 1 can squeeze and deform the bending part of the expanding piece 31, the end part of the expanding piece 31 stretches along the axial direction of the inner wall of the pre-opened slot hole, after the deformation of the bending part, the side wall of the bending part is flush with the inner wall of the fastening ring 3, and meanwhile, the edges of the upper side wall and the lower side wall of the expanding piece 31 are in line contact with the inner wall of the pre-opened slot hole to generate static friction force, so that the fastening ring 3 can rotate and the fastening ring 3 is limited, and the fastening ring 3 can be prevented from rotating the sound 1 synchronously. Screw thread at the end part of the sound equipment 1 into the fastening ring 3, and simultaneously support the expanding and supporting piece 31 against the edge of the pre-opened notch to block the notch of the column, thereby realizing quick installation of the sound equipment 1, and the fastening piece is not required to be fixed in the pre-opened notch of the ceiling in advance, so that the installation is convenient and quick.
Meanwhile, when the loudspeaker is disassembled, the loudspeaker 1 and the fastening ring 3 can be separated only by reversing the loudspeaker 1, and after the end part of the loudspeaker 1 is pulled out of the fastening ring 3, the bending part of the expanding and supporting piece 31 is reset, so that the edge of the upper side wall and the lower side wall of the expanding and supporting piece 31 are separated from the inner wall of the pre-opened slotted hole, the fastening piece is conveniently taken out from the pre-opened slotted hole, the installation position is conveniently replaced, and the installation cost is saved.
Further, as shown in fig. 5 and 6, a spherical block 35 is fixed on the side wall of the bending portion of the expansion piece 31, a plurality of clamping grooves 11 are formed in the outer wall of one end of the sound equipment 1 away from the expansion portion, the clamping grooves 11 are in a circular arc structure, and the spherical block 35 is clamped with the inner wall of the circular arc structure of the clamping grooves 11. The process post that the tip of stereo set 1 was screwed into in the clamping ring 3, a plurality of card dun grooves 11 of stereo set 1 can cross ball-shaped piece 35 in proper order, until the expansion portion of stereo set 1 supports on the ceiling is offered slotted hole opening lateral wall in advance, ball-shaped piece 35 can support in corresponding card dun groove 11, the purpose of setting like this is, after the tip of stereo set 1 is screwed into in the clamping ring 3, can not reverse rotation break away from the clamping ring 3 easily.
Of course, a plurality of rectangular notches may be provided at the end of the expanding and supporting piece 31, and the portion of the expanding and supporting piece 31 located at two adjacent rectangular notches is a deformation end. As shown in fig. 7, when the expansion sheet 31 is rotated and screwed into the fastening ring 3, the bending parts of the two expansion sheets 31 are expanded, the side walls of the expansion sheet 31 are propped against the inner wall of the pre-opened hole slot of the ceiling, and meanwhile, the deformation ends are correspondingly deformed due to extrusion of the outer wall of the end part of the sound box 1, and the deformation ends are propped against the inner wall of the pre-opened hole slot of the ceiling after deformation, so that the contact surface between the expansion sheet 31 and the inner wall of the hole slot is enlarged, the friction force of the expansion sheet 31 when propping against the inner wall of the hole slot is further enhanced, the rotation resistance of the fastening ring 3 is increased, and the fastening ring 3 is prevented from following the synchronous rotation of the sound box 1.
In this embodiment, as shown in fig. 1, the fastener further includes a limit baffle 32, two ends of the side wall of the limit baffle 32 facing the fastening ring 3 are fixed with a connecting rod 33, and the connecting rod 33 is fixedly connected with the side wall of the fastening ring 3. The side wall of one side of the limit baffle 32 facing the sound 1 is symmetrically extended with two elastic limit pieces 34, the end parts of the two elastic limit pieces 34 are bent and extended towards one end close to each other, and a deformation gap is arranged between the end parts of the two elastic limit pieces 34. The limit baffle 32 is used as a limit structure for rotating and screwing in the sound 1, and as the end part of the sound 1 is continuously screwed in, the limit baffle can abut against the end parts of the two elastic limit sheets 34, the end parts of the two elastic limit sheets 34 are bent and deformed after being extruded, and the rebound potential energy is generated to abut against the side wall of the end part of the sound 1, so that the sound 1 is prevented from reversely rotating and loosening.
A plurality of openings are formed in the radial side wall of the expansion part, and the auxiliary rotating sound box 1 is convenient to screw in and unscrew from the fastening ring 3 by arranging the openings. The sealing washer 2 of ripple structure has been cup jointed to stereo set 1 outer wall, as shown in fig. 2, through addding ripple structure's sealing washer 2, has compression set's characteristic, when stereo set 1 precession fastening ring 3, can compress sealing washer 2, improves the laminating degree between expansion and the notch edge lateral wall.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
