Abstract
The utility model discloses a loudspeaker box mesh enclosure connecting structure comprising a box body and a mesh enclosure. The box body comprises a bottom plate, a top plate, a left side plate, a right side plate, a front plate and a rear plate. The front part of the box body is provided with a clamping groove. The side of the mesh enclosure is clamped inside the clamping groove. The middle part of the inner surface of the mesh enclosure is provided with a connecting pillar which extends backwards. A screw passes through the front plate from the rear surface of the front plate and connects the connecting pillar. According to the loudspeaker box mesh enclosure connecting structure, the connecting pillar is arranged on the middle part of the mesh enclosure and is connected by the screw so that a connection to the middle part of the mesh enclosure is strengthened apart from the realization of the mesh enclosure connection via the clamping groove. Therefore, the mesh enclosure is not easy to deform, and the fixing of the mesh enclosure is also quite reliable.
Description
Technical field
The utility model relates to audio amplifier, particularly the sound box mesh cover syndeton.
Background technology
Existing audio amplifier mainly is comprised of casing, guard, circuit board, loudspeaker etc., existing guard normally connects by the mode that snaps in, as being to be to disclose a kind of audio amplifier in the patent documentation on May 30th, 2,008 200820088409.3 applyings date at application number, comprise casing and elasticity guard, described casing each side be provided with a groove, the elasticity guard left and right sides is stuck in the groove of the casing left and right sides.The audio amplifier of said structure when the size of guard is larger, only utilizes groove stationary positioned guard, and then the middle part of guard is out of shape easily, thus cause fixing unreliable.
Summary of the invention
For solving the problems of the technologies described above, the utility model has improved a kind of sound box mesh cover syndeton.
The technical scheme that solves the problems of the technologies described above is: a kind of sound box mesh cover syndeton, comprise casing and guard, casing comprises base plate, top board, left plate, right plate, front panel and rear plate, is provided with draw-in groove in the front portion of casing, and the side holding of guard is in draw-in groove; In the middle part of being positioned at, the inner surface of guard is provided with the joint pin that extends back; Screw passes front panel from the rear surface of front panel and is connected with joint pin.
As improvement, described joint pin comprises the first joint pin, the second joint pin, the 3rd joint pin and the 4th joint pin, the central axis of the first joint pin and the second joint pin is in the same level face, the 3rd joint pin and the 4th joint pin are on the same level face, and the spacing between the first joint pin and the second joint pin is greater than the spacing between the 3rd joint pin and the 4th joint pin.
The beneficial effects of the utility model are: owing to be provided with joint pin at the middle part of guard, and utilize screw to connect, and therefore, except realizing that by draw-in groove guard connects, also strengthened the connection at guard middle part, like this, guard is not easy distortion, fixing also very reliable of guard.Since between first, second, third, fourth joint pin special spacing requirement is arranged, so that the connection bit of guard is more reasonable, the fixing more science of guard.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figures 1 to 4, the sound box mesh cover syndeton comprises casing 1, guard 2 and ornamental strip 3.Casing 1 is made of base plate 11, top board 12, left plate 13, right plate 14, front panel 15 and rear plate, the casing front surface has the cavity 4 that caves inward, in the present embodiment, cavity 4 is formed by base plate 11, top board 12, left plate 13, right plate 14 and front panel 15.
As shown in Figure 2, ornamental strip 3 is installed on the left and right side plate that is positioned at cavity 4.As shown in Figure 4 and Figure 5, be formed with draw-in groove 32 between ornamental strip 3 and the front panel 15.And in order to dismantle ornamental strip 3, be provided with the decorative groove 34 of downward-extension in the front of ornamental strip 3.And this decorative groove can also play the effect of decoration.
As shown in Figure 4 and Figure 5, guard comprises cover body 21, connecting portion 22 and side 23, the cross section camber of cover body 21, connecting portion 22 is from the side of cover body bending forming backward, side 23 is connected on the connecting portion 22, and cover body 21, connecting portion 22 and side 23 are one-body molded, and side 32 is entrapped in the draw-in groove.
As shown in Figure 6, in the middle part of being positioned at, the inner surface of cover body 21 is provided with the joint pin that extends back, joint pin comprises the first joint pin 51, the second joint pin 52, the 3rd joint pin 53 and the 4th joint pin 54, the central axis of the first joint pin 51 and the second joint pin 52 is in the same level face, the 3rd joint pin 53 and the 4th joint pin 54 are on the same level face, and the spacing between the first joint pin 51 and the second joint pin 52 is greater than the spacing between the 3rd joint pin 53 and the 4th joint pin 54; Screw passes front panel from the rear surface of front panel and is connected with joint pin.
Said structure except realizing that by draw-in groove guard connects, has also been strengthened the connection at guard middle part, and like this, guard is not easy distortion, fixing also very reliable of guard.Since between first, second, third, fourth joint pin special spacing requirement is arranged, so that the connection bit of guard is more reasonable, the fixing more science of guard.
