Detailed description of the invention
The present invention is described further with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-Figure 4, the dismantling device of the temperature-sensitive smoke detector that the present embodiment provides, including support arm 10 and peace
It is contained in the dismounting 20 of support arm 10 one end.
Dismounting 20 includes that the pedestal 21 being installed together with support arm 10 and two one end are rotatably connected on pedestal respectively
Rosette 22 on 21, the concrete mode that is rotationally connected can be in the way of being conventional, in the present embodiment, pedestal 21 and rosette
22 are rotationally connected by a rotary shaft, and rotary shaft two ends use butterfly nut to fasten.
Two rosettes 22 are arranged in opposite directions, and both snap together rear tapered lamp tubular, the opening of this taper lamp tubular
For coordinating with temperature-sensitive smoke detector 30.Rosette 22 be respectively provided on two sides with chute 23, be positioned at two chutes of the same side
It is interspersed with the first screw rod 24 that can simultaneously slide on two chutes 23 on 23, that is to say that the first screw rod 24 has two, same
Two chutes 23 that individual first screw rod 24 passes are on different rosettes 22.The two ends of the first screw rod 24 are respectively mounted
There are the first nut 25 for limiting rosette 22 position, each first nut 25 and the rosette 22 near this first nut 25
Between be additionally provided with in the pad (not shown) being set on corresponding first screw rod 24, i.e. each first screw rod 24 and have
Two pads.First nut 25 is preferably butterfly nut, it is simple to screw by hand.
Also being arranged with spring 26 on first screw rod 24, this spring 26 is stretching spring, its two ends or the coupling part at two ends
Chute 23 that Chuan Guo be not corresponding is fixed on two pads, and the fixed form between spring 26 and pad can be conventional side
Formula, but it is necessary to ensure that spring can slide on corresponding chute 23 along with the first screw rod 24.
The keeper (not shown) for fixing first screw rod 24 position on chute 23 it is provided with on chute 23,
Keeper can be conventional part, and the screw and nut cooperated such as employing, by being interspersed in screw on chute 23 also
It is fastened on ad-hoc location with nut, stops the slip on chute 23 of first screw rod 24, the most no longer describe in detail.
During use, the dimensions of the temperature-sensitive smoke detector 30 dismounted as required, the first screw rod 24 is adjusted to sliding
Appropriate location on groove 23, fixes the position of the first screw rod 24 with keeper, then regulates the first nut 25 corresponding
Position on one screw rod 24 so that two expandable maximums of rosette 22 are opened bore and are equal or slightly larger than temperature-sensitive smoke detection
The dimensions of device 30, is now in, due to spring 26, the naturalness not stressed, and opens bore between two rosettes 22
Being slightly less than the dimensions of temperature-sensitive smoke detector 30, certainly, now the caliber size of opening between two rosettes 22 depends on
Length under spring 26 naturalness and first screw rod 24 particular location in chute 23.
Then temperature-sensitive smoke detector 30 is inserted in toward the opening between two rosettes 22 so that temperature-sensitive smoke detector
30 contact with each other with two rosettes 22, and being inserted in along with temperature-sensitive smoke detector 30, two rosettes 22 softened and point
Not promoting corresponding pad to support on corresponding first nut 25, now two rosettes 22 open up into and temperature-sensitive smoke detection
What the dimensions of device 30 matched opens bore, and spring 26 is stretched, and two rosettes 22 are held tightly under the effect of spring 26
Temperature-sensitive smoke detector 30；Then pass through support arm 10 and rotate dismounting 20, under the effect of frictional force, temperature-sensitive smoke detector
The probe of 30 follows first rotation of dismounting, and then makes this probe separate from the base of temperature-sensitive smoke detector 30 or install
On the base of temperature-sensitive smoke detector 30.
Preferably, in the present embodiment, two rosettes 22 side in opposite directions is respectively arranged with flexible glue layer 27, flexible glue layer 27
Upper the evenest it is furnished with multiple salient point 28 for increasing frictional force, so can increase rubbing of flexible glue layer 27 and temperature-sensitive smoke detector 30
Wiping power, it is simple to dismounting.Flexible glue layer 27 can be rubber layer or layer of silica gel.
Additionally, the flexible glue layer 27 in the present embodiment is in strip, it is fitted in close rosette 22 one end away from pedestal 21, with
Time, rosette 22 post one section of flexible glue layer 27 in arc-shaped, do not post the spherical calotte shape of flexible glue layer 27.So can facilitate
Being inserted in of smoke sensing device 30.
Preferably, in the present embodiment, pedestal 21 include the installation portion 21a for connecting rosette 22 and with support arm 10
One end of the connecting portion 21b being installed together, connecting portion 21b remotely mounted portion 21a is provided with U-type groove 21c, the end of U-type groove 21c
Portion has toothing 21d, toothing 21d and has the tooth on multiple similar rack structure.It is further opened with on the sidewall of U-type groove 21c
First installing hole 31.
One end of support arm 10 is interspersed in U-type groove 21c, and this end has the teeth portion 11 coordinated with toothing 21d.Support
Arm 10 has on the position that one end of teeth portion 11 is corresponding with the first installing hole 31 on pedestal 21 and offers the second installing hole 32,
Being interspersed with the second screw rod 12 on first installing hole 31 and described second installing hole 32, the two ends of the second screw rod 12 are respectively mounted simultaneously
Having the second nut 13, in the present embodiment, the second nut 13 is also butterfly nut.
During use, the tooth being mutually twisted with teeth portion 11 by regulation toothing 21d so that support arm 10 and pedestal 21 are formed
Predetermined angle, is then fixed by screwing the second nut 13, and the connection between support arm 10 and pedestal 21 is more firm.
Preferably, in the present embodiment, one end that support arm 20 is not interspersed in U-type groove 21c connects has extension arm (in figure
Not shown), extension arm can be conventional expansion link, and the annexation between itself and support arm 20 can also be conventional side
Formula, the most no longer describes in detail.Extension arm can carry out with personnel convenient to operate dismounting operation at a distance, and without by means of ascending a height
Instrument.
Above in conjunction with accompanying drawing, the present invention is described in detail, but embodiments of the present invention are not limited in above-mentioned
Embodiment, the present invention can be made various deformation according to prior art by those skilled in the art, as by above-described embodiment
Butterfly nut be changed to routine nut etc., these broadly fall into protection scope of the present invention.
