In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-3, a buzzer assembly casing convenient for assembly comprises an impact-proof casing and a base. Protecting against shock shell 1 includes protective housing 11, the connecting ring 12, buffer spring 13, protecting against shock board 14 and fixed cover 15, protective housing 11 is hollow cylindrical shell and is used for installing bee calling organ, the top at protective housing 11 is installed to connecting ring 12, fixed cover 15 is located the bottom of protective housing 11, spacing hole 16 has been seted up to fixed cover 15's side, connect the opening 17 has been seted up to spacing hole 16's bottom, connect the opening 17's top and spacing hole 16 to the intercommunication, connect the opening 17's bottom extends to fixed cover 15's side and opening downwards, protecting against shock board 14 installs the outside at protective housing 11, be connected through multiunit buffer spring 13 between protecting against shock board 14 and the protective housing 11. The base 2 is cylindrical, the top end of the base 2 is sleeved outside the fixed sleeve 15, and the base 2 internally comprises a first spring 21, a limiting block 22, a rope 23 and a pulling plate 24; one end of the first spring 21 is connected to the inner side wall of the base 2, the other end of the first spring 21 is fixedly connected with a limiting block 22, one end, originally away from the first spring 21, of the limiting block 22 is connected with a rope 23, the rope 23 extends to the outside of the base 2, and a pulling plate 24 is arranged at the end part of the rope 23;

base 2 detachably installs in the bottom of protecting against shock shell 1, and stopper 22 inserts to spacing downthehole 16, and stopper 22's diameter is greater than connection opening 17's diameter, and first spring 21's diameter is less than connection opening 17's diameter, and when outside pulling arm-tie 24, rope 23 drives stopper 22 and removes to the inside of fixed cover 15, and stopper 22 crosses spacing hole 16, and first spring 21 stretches to spacing hole 16 directly over.

When the anti-impact shell is used, the buzzer circuit part is sleeved into the anti-impact shell 1, the fixing sleeve 15 at the bottommost part of the anti-impact shell 1 is inserted into the base 2, the position of the anti-impact shell 1 is adjusted in a rotating mode, so that the connecting opening 17 in the fixing sleeve 15 is aligned to the limiting block 22 on the inner wall of the base 2, when the fixing sleeve 15 is pressed down, the limiting block 22 cannot enter the limiting block 22 and can only be extruded outwards due to the fact that the diameter of the connecting opening 17 is smaller than that of the limiting block 22, and the first spring 21 is driven to be compressed; when fixed cover 15 pushes down to spacing hole 16 alignment stopper 22, because the diameter of spacing hole 16 is greater than stopper 22's diameter, consequently first spring 21 extends to kick-back, and stopper 22 inserts spacing downthehole 16 internal fixation block, upwards mentions protecting against shock shell 1 this moment again, can't pull down it from base 2 to realize the fixed purpose of quick installation.

When needs are dismantled impact shell 1 from base 2, only need outwards to stimulate arm-tie 24, arm-tie 24 drives rope 23 and outwards stretches, rope 23 drives stopper 22 and removes to base 2 is inside, first spring 21 is tensile, until stopper 22 passes spacing hole 16, be the first spring 21 after drawing in the spacing hole 16 this moment, because first spring 21's diameter is less than connection opening 17, consequently upwards mention impact shell 1 again this moment, spacing hole 16 and connection opening 17 just can follow first spring 21 and remove, impact shell 1 is taken off, thereby realize the purpose of quick dismantlement.

The utility model discloses installation protecting against shock board 14 and buffer spring 13, when protecting against shock shell 1 atress, protecting against shock board 14 at first atress, secondly buffer spring 13 carries out offsetting of power for the device can effectually cushion the shock attenuation. The impact-proof plate 14 may be made of a soft, insulating and high-toughness material such as rubber.

In one embodiment, there are two sets of the limiting holes 16 and the connecting openings 17, and the two sets of the limiting holes 16 and the connecting openings 17 are oppositely arranged on the side surface of the fixing sleeve 15; the first springs 21 and the limiting blocks 22 are divided into two groups, the two groups of first springs 21 and the limiting blocks 22 are oppositely arranged on the inner side wall of the base 2, and each group of first springs 21 and the limiting blocks 22 corresponds to one group of limiting holes 16 and connecting openings 17; still be equipped with two gag lever posts 25 on base 2's the inside wall, gag lever post 25 is installed in one side of keeping away from first spring 21 of stopper 22, and gag lever post 25 perpendicular to stopper 22's extending direction installation, and the rope 23 walks around gag lever post 25 and wears out base 2.

The side surfaces of the fixed sleeve 15 and the base 2 are symmetrically provided with two sets of opposite clamping and disassembling structures which comprise a limiting hole 16, a connecting opening 17, a first spring 21 and a limiting block 22, so that a better clamping and fixing effect can be achieved. In addition, the stopper rod 25 functions to restrict the direction of the tensile force of the rope 23 so that the stopper 22 can move only in the axial direction of the stopper hole 16.

In one embodiment, the limiting hole 16 is a cylindrical through hole formed on the side surface of the fixing sleeve 15, and the limiting block 22 is a slope cylinder with a top end close to the first spring 21 and a bottom end away from the first spring 21. Because when the installation, stopper 22 is not being aimed at with spacing hole 16 before by fixed cover 15 extrusion, need outwards extrude first spring 21 by oneself for fixed cover 15 can continue to move down until spacing hole 16 aims at stopper 22, consequently sets the one side that is close to fixed cover 15 of stopper 22 to the inclined plane, and when fixed cover 15 pushed down, spacing hole 16 moved backward along the inclined plane fast, makes during the installation more smoothly, but does not influence fixed effect.

Preferably, the connection opening 17 is a rectangular through hole opened in the side of the fixing sleeve 15.

In one embodiment, a dustproof layer 18 is installed on the inner side of the connecting ring 12, a waterproof layer 19 is installed on the inner side of the dustproof layer 18, and circuit components are installed inside the waterproof layer 19.
