Fig. 3 is the schematic diagram of the utility model structure stop collar;
Fig. 4 is enlarged drawing at A in the utility model structure chart 3.
In figure: 1 loudspeaker ontology, 2 mounting cups, 3 stop collars, 4 dust caps, 5 first sheet metals, 6 second sheet metals, 7 caps It holds in the palm, union thimble, 9 limited blocks, 10 bayonets, 11 loose slots, 12 sliding blocks, 13 kellies, 14 reset springs, 15 square grooves, 16 are pulled back in 8 Bar.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs 1-4, the utility model provides a kind of technical solution: it is a kind of to prevent shrivelled sound equipment dust cap, including raise Sound device ontology 1, the top of loudspeaker ontology 1 are fixedly connected with mounting cup 2, and the top of mounting cup 2 is fixedly connected with restraining position ring block 3, Dust cap 4 is socketed in mounting cup 2, the top of dust cap 4 is fixedly connected with interior union thimble 8, and interior union thimble 8 is socketed in stop collar 3;
Interior 8 side surface of union thimble is equidistant to be fixedly connected there are four limited block 9, and limited block 9 is socketed in 3 inner sidewall of stop collar and opens If bayonet 10 in, the effect of bayonet 10 can be positioned quickly, and limited block 9 is stuck in bayonet 10 can quickly will be dust-proof Cap 4 is installed;
Side on stop collar 3 close to bayonet 10 offers loose slot 11, and sliding block 12, sliding block 12 are socketed in loose slot 11 Side be fixedly connected with kelly 13, one end of kelly 13 is plugged in the limited mouth that 9 side of limited block opens up, sliding block 12 it is another Side is fixedly connected with bar 16 of pulling back, and the square groove 15 that the bottom end of bar 16 of pulling back is opened up through the bottom of 11 inner wall of loose slot and prolongs Extend to the lower section of interior union thimble 8, the side elastic connection of sliding block 12 and 11 inner wall of loose slot, when dismantling dust cap 4, relative direction The bar 16 of pulling back in two left sides or two right sides is squeezed, sliding block 12 can slide in square groove 15, at this time the one of kelly 13 End is detached from the state of clamping with the limited mouth that 9 side of limited block opens up, and be capable of block picks up dust cap 4, so as to convenient pair Inside carries out inspection operation, and the placement of more existing screw installation is more convenient and quick, reduces the time of maintenance;
The bottom of interior union thimble 8 is equidistant to be fixedly connected there are three the first sheet metal 5, and one end of the first sheet metal 5 is fixed to be connected It is connected to the second sheet metal 6, the top of three the second sheet metals 6 is fixedly connected with hat holder 7, the first sheet metal 5, the second sheet metal 6 It is overlapped with the side of dust cap 4 with the side of hat holder 7, after installing dust cap 4, due to the first sheet metal 5, the second sheet metal 6 and the side of hat holder 7 overlapped with the side of dust cap 4, also by external power under long-time use, the first sheet metal 5, Second sheet metal 6 and hat holder 7 can be supported dust cap 4, so as to ensure that the service life of dust cap 4, avoid There is the appearance of the case where shrivelled or deformation in dust cap 4.
Specifically, the side surface of mounting cup 2 is set as grid-like, the outer wall of interior union thimble 8 and the inner wall of stop collar 3 are overlapped, The outer wall of interior union thimble 8 generates biggish frictional force by increasing the area contacted with the inner wall of stop collar 3 overlap joint, to ensure that Dust cap 4 install compactness, sound shake in the case where be not in loosening the problem of.
Specifically, the first sheet metal 5, the second sheet metal 6 and hat holder 7 are that metal aluminium material is made, aluminium material is easy to oxygen Solid/liquid/gas reactions have the function of antirust, and material is harder increases crushing resistance, to guarantee the crushing resistance of dust cap 4.
Specifically, the side of sliding block 12 is fixedly connected, there are two reset spring 14, one end of reset spring 14 and loose slots The side of 11 inner walls is fixedly connected, and under the elastic reaction of reset spring 14,9 clamping of limited block can be avoided preventing by kelly 13 Dirt cap 4 loosens, and ensure that dust cap 4 fastness and stability in mounting cup 2.
Certainly optimal, the upper surface that kelly 13 is located at one end of bayonet 10 offers curve slope, in installation dust cap 4 On interior union thimble 8 when, when limited block 9 is sticked into bayonet 10, limited block 9 contacted with curve slope generate sliding, can be by card Bar 13 instead promotes in loose slot 11, when the limited mouth on limited block 9 reaches one end of kelly 13, in the effect of reset spring 14 Under, kelly 13 can be in clamping limited mouth, and then installs convenient for operator.
Specifically, the shape of hat holder 7 is adapted with the shape at the top of 4 inner wall of dust cap, hat holder 7 and dust cap 4 are increased Contact area ensure that the safety of 4 high spot of dust cap.
