Embodiment
By reference to the accompanying drawings the application is described in further detail below by embodiment.
Refer to Fig. 1, for the one stand alone type smoke fire detector that the application one embodiment provides, it comprises upper cover 3, lower cover 2, base 1 and kernel component, and upper cover 3 covers formation installing space mutually with lower cover 2, kernel component is installed in this installing space, and upper cover 2 bottoms are connected with base 1.
Refer to Fig. 1, Fig. 2 and Fig. 3, lower cover 2 comprises lid 21 and is arranged at the cylinder boss 23 of lid 21 central authorities, three snap fits 22 and for the battery case 24 of battery 4 is installed, three snap fits 22 are equidistantly distributed in take cylinder boss 23 centers on the circumference in the center of circle, battery case 24 is provided with elasticity column 25 near cylinder boss 23 1 sides, elasticity column 25 comprises lug boss 251, contact site 252 and extension, lug boss 251 is holistic strip with contact site 252, lug boss 251 is upper, for limiting lower cover 2 rotating relative to base, elasticity column 25 is connected with battery case 24, contact site 251 extends in battery case 24, relative with battery 4 one sides, lug boss 251 extends to described battery case 24 tops by described contact site 252, extension 253 is for adding the intensity of strong elasticity column 25, strengthen elasticity, can there is no extension 253 yet.
Refer to Fig. 4, snap fit 22 front ends are provided with projection 224, and rear end is provided with identification boss 222, and bottom is also provided with groove 223.Identification boss 222 on three snap fits 22 is in the distributing position difference of corresponding snap fit 22 rear ends.
Refer to Fig. 1, Fig. 5 and Fig. 6, base 1 is substantially rounded, comprises a pedestal 15, and pedestal 15 central authorities are manhole 14, cylinder boss 23 clearance fit on through hole 14 and lower cover 2, make lower cover 2 relatively base 1 be rotated take this cylinder boss 23 as rotating shaft.Through hole 14 arranges an annular leg 13 around, and annular leg 13 is provided with breach 132 in a side, and breach 132 runs through leg 13.The porch of breach 132 is also provided with enlarging 131, the width of enlarging 131 is greater than the width of breach 132, when the meaning that enlarging 131 is set is to prevent neglected loading battery 24, lug boss 251 is first pushed toward lower cover 2 centers by leg 13, in the time that snap fit 22 drops into connecting hole 11, lug boss 251 does not carry out interlock with the breach 132 of base 1, and lower cover 2 is directly rotated in base 1.Arrange after enlarging 131, in the time that snap fit 22 will drop into connecting hole 11, due to the existence of enlarging 131, leg 13 can not form to the extruding at lower cover 2 centers jut 251, guarantee the normal occlusion of lug boss 251 and base breach 132.Breach 132 matches with the lug boss 251 on lower cover 2, and when installation, if do not pack battery in battery case 24, breach 132 snaps in lug boss 251, and limits lower cover 2 and rotate relative to base 1.
Pedestal 15 edges arrange three connecting holes 11 along circumference, the snap fit 22 on the corresponding lower cover 2 of each connecting hole 11.Connecting hole 11 1 ends are provided with the identification slot corresponding with identifying boss 222 112, when installation, only have in the time that all snap fits 22 are all aimed at corresponding connecting hole 11, and identification boss 222 is during with corresponding identification slot 112 successful matching, snap fit 22 could insert connecting hole 11.Each connecting hole 11 one end, bottom arranges a fastening plate 13, the other end arranges a block 14, fastening plate 13 all extends to connecting hole 11 with block 14, and block 14 is placed in fastening plate 13 bottoms, between the two every setting, when connection, snap fit 22 gos deep in connecting hole 11, and rotation lower cover 2, makes snap fit 22 snap in fastening plate 13 bottoms, block 14 tops, make lower cover 2 realize and being connected with base 1.And, snap fit 22 arranges respectively relative projection with fastening plate 13 front ends, when lower cover 2 is connected with base 1, snap fit 22 snaps in from fastening plate 13 bottoms, projection on snap fit 22 is crossed the projection on fastening plate 13, make snap fit 22 tightr with engaging of fastening plate 13, prevent that snap fit 22 from skidding off from fastening plate 13.The one side matching at block 14 snap fits 22 is also provided with projection 141, and when connection, this projection 141 snaps in the groove 223 of snap fit 22 bottoms, and block 14 clamps snap fit 22 jointly with fastening plate 13, makes engaging tightr, and prevents that snap fit 22 from deviating from.
The quantity that should be appreciated that snap fit 22 and connecting hole 11 can also be two or more than three.Fastening plate 13 can be also that other can realize the snap fit auxiliary section engaging with snap fit 22.
On base 1, arrange and snap fit 22 connecting hole 11 and fastening plate 13 one to one, fastening plate 13 is arranged at connecting hole 11 1 sides;
Also comprise a compression spring 26, described compression spring 26 one end are connected on lower cover 2, and the other end is resisted against elasticity column 25 back sides, elasticity column 25 is remained and have the trend of moving towards battery case 24.Should be appreciated that this compression spring 26 also can be substituted by the flexible member of rubber blanket etc. and so on.
When assembling, kernel component is placed in the installing space between upper cover 3 and lower cover 2, and upper cover 3 covers mutually with lower cover 2, then battery 4 will be installed in lower cover 2.
When installation, first base 1 is fixed on to installation site, battery 4 is placed in battery case 24 again, then lower cover 2 is placed on base 1, lower cover 2 can rotate around base 1, in the time rotating to appropriate location, snap fit 22 aligns with corresponding connecting hole 11 respectively, slightly extruding rotation, and snap fit 22 inserts in connecting hole 11 automatically, make lower cover 2 realize and being connected with base 1, complete installation.In installation process, if neglected loading battery 4, elasticity column 25 is not squeezed, lug boss 251 will engage with breach 132, restriction lower cover 2 rotates relative to base 1, and snap fit 22 inserts after corresponding connecting hole 11, and snap fit 22 cannot snap in fastening plate 13, lower cover 2 also cannot be connected with 1 realization like this, installs unsuccessful.So, only have in the time that this stand alone type smoke fire detector is correctly provided with battery 4, the contact site 252 on battery extrusion elasticity column 25, lug boss 251 disengagings engage with breach 132, and lower cover 2 could rotate relative to base 1, could realize final installation process.So just can avoid neglected loading battery 4, get rid of potential safety hazard, improve the security performance of fire-fighting system.
The free-standing smoke fire detector that the application provides stretches to the lug boss 251 in battery case 24 by setting, the breach 132 of corresponding matching is set on base 1, this stand alone type smoke fire detector is only had when mounted and be installed on battery case 24 when interior when battery 4, lower cover 2 could further rotate relative to base 1, thereby realizes the engagement connection of lower cover 2 and base 1.If battery 4 is not installed, lug boss 251 will engage with breach 132, and lower cover 2 cannot rotate relative to base 1, the snap fit 22 on lower cover 2 also cannot with base 1 on fastening plate 13 fasten.So just can prevent detector neglected loading battery 4 in installing, eliminate potential safety hazard, improve security.
Above content is the further description of the application being done in conjunction with concrete embodiment, can not assert that the application's concrete enforcement is confined to these explanations.For the application person of an ordinary skill in the technical field, not departing under the prerequisite of the application's design, can also make some simple deduction or replace.
