Embodiment
Be described at a kind of fixing device that is used to install combustible gas detector below in conjunction with accompanying drawing, in the hope of the related technological scheme of the utility model there being a understanding more clearly.
Figure 2 shows that the fixing bottom-plate example structure schematic representation of the fixing device that the utility model provides.In this embodiment, the mounting base that fixing device comprises fixing bottom-plate and is used for cooperating with fixing bottom-plate, being used for wall hanging installation combustible gas detector with fixing device is example, and mounting base can be used as the part of combustible gas detector, is used for combustible gas detector and installs and fixes.The concrete application area of fixing device is not limited by the utility model.As shown in Figure 1, fixing bottom-plate 20 comprise base plate main body 21, on collude and hang pawl 22, collude and hang pawl 23, first shell fragment 24, second shell fragment 25 and mounting hole 26 down.Mounting hole 26 perforates are in base plate main body 21, mounting hole can be but be not limited only to be tapped hole, behind the attachment screw, fixing bottom-plate 20 can be fixed on wall, cupboard wall or the ceiling board (therefore, this fixing device goes for various wall-hanging but be not limited only to wall-hanging fixed installation), the number of mounting hole is not limited by the utility model, and in this embodiment, mounting hole 26 is two.Base plate main body 21 is a planar, and it can be close to places such as wall or ceiling board, and the shape of base plate main body 21 is not limited by the utility model yet, and in this embodiment, base plate main body 21 is approximately square shape.The top and bottom of base plate main body 21 are provided with respectively to collude and hang pawl 22 and collude down and hang pawl 23, on collude and hang pawl 22 and extend out from the upper end of base plate main body 21, collude extension pawl 23 down and extend out from the lower end of base plate main body 21.Face both sides, base plate main body 21 place are provided with first shell fragment 24 and second shell fragment 25 respectively, and the type of shell fragment and quantity are not limited by the utility model, and in the present embodiment, shell fragment is that the fixing bottom-plate by rigid material rolls and cuts a part and make.First shell fragment 24 and second shell fragment 25 are used for forming Elastic Contact with mounting base when mounted, thereby shell fragment produces elastic force to mounting base.
Fig. 3 is the A-A cross section structure schematic representation of fixing bottom-plate embodiment illustrated in fig. 2.As shown in Figure 2, can clearly be seen that to collude and hang pawl 22, collude the relative position relation of hanging pawl 23, first shell fragment 24 and fixing bottom-plate 21 down.On collude and hang pawl 22, under collude and hang pawl 23, shell fragment is all with respect to 211 (being the left side of fixing bottom-plate 21 among Fig. 2) projections of fixing bottom-plate 21, the height of shell fragment projection is not limited by present embodiment, preferably, the height of shell fragment projection is greater than colluding the height of hanging the pawl projection, when installing and fixing with assurance, fixing bottom-plate 21 is easier to be in the Elastic Contact state with mounting base 30, in addition, shell fragment also can be hung the height of pawl with respect to the fixing bottom-plate projection less than colluding with respect to the fixing bottom-plate rising height, the height design of shell fragment projection, as long as when guaranteeing to install, mounting base and fixing bottom-plate can be realized Elastic Contact.
Figure 4 shows that the structural representation of present embodiment fixing device before rotation is installed.As shown in Figure 4, in this embodiment, fixing device is used for fixing combustible gas detector, wherein, 40 is combustible gas detector, and 30 is the mounting base of fixing device, 20 is the fixing bottom-plate of fixing device, and mounting base 30 is the part of combustible gas detector 40.Mounting base 30 comprises that first colludes hanging groove 33, second and collude hanging groove 32, swivelling chute 31.First collude hanging groove 33 and second collude hanging groove 32 be used for respectively corresponding embed to collude on fixing hang pawl 22 and collude extension pawl 23 down, swivelling chute 31 is the depressed structure, so as mounting base 30 when contacting with fixing bottom-plate 20 two of fixing bottom-plate upper process collude and hang pawl and all can stretch in the swivelling chute 31; Swivelling chute 31 with collude hanging groove and be all sunk structure, and swivelling chute 31 communicates with adjacent side one end that colludes hanging groove, falls into colluding the extension pawl and can rotating into from swivelling chute 31 and collude hanging groove of swivelling chute 31 thereby make.
Figure 5 shows that the structural representation of present embodiment fixing device after rotation is installed.In conjunction with Fig. 4 and shown in Figure 5, the fixed installation process of this fixing device can be described, at first, fixing bottom-plate 20 is fixed on the wall at a certain angle; Second step, the swivelling chute in the mounting base 30 of combustible gas detector 40 31 to be aimed to collude hang pawl 22 and collude extension pawl 23 down, mounting base 30 contacts with shell fragment 24; The 3rd step, push combustible gas detector 40, overcome the elastic force of shell fragment, on collude to hang pawl 22 and collude down and hang pawl 23 and further stretch in the swivelling chute 31, then, rotate combustible gas detector, make to collude and hang pawl and go into to collude the hanging groove, rotate to and to be rotated further from a sidespin that communicates with swivelling chute; At last, unclamp combustible gas detector, under the elastic force effect of shell fragment, on collude to hang pawl 22 and collude extension pawl 23 down and embed first respectively and collude hanging groove 33, second and collude in the hanging groove 32, and under the effect of self-locking block 331, can not deviate from, and combustible gas detector 40 this moment vertical fixing just in time, thereby realized that finally the wall-hanging of combustible gas detector installs and fixes.In this embodiment, the mounting inclination angle degree of adjusting fixing bottom-plate is suitable, and the angle of swing of concrete installation process is by the swivelling chute 31 of prior design and the angle decision of colluding hanging groove, after guaranteeing that rotation is installed, combustible gas detector just in time is in plumbness, thereby makes installation attractive in appearance.Certainly, finally install and fix the visual concrete condition of angle, suitably select.
Figure 6 shows that the perspective view of the fixing device part of structure shown in Figure 5.As shown in Figure 6, can find out clearly that fixing device rotation installs the spatial relation between back fixing bottom-plate 20 and the mounting base 30.First of mounting base 30 is colluded hanging groove 33 and second and is colluded and be provided with self-locking block 331 on the hanging groove 32, and self-locking block 331 is arranged at and colludes the side that hanging groove communicates with swivelling chute 31, and what self-locking block 331 was used for fixing embedding colludes the extension pawl, prevents to collude to hang pawl and skid off.At the unloading process of this fixing device, push combustible gas detector, overcome shell fragment elastic force after, contrary direction (opposite with the sense of rotation of installing) is rotated flammable prober, colludes to hang pawl and can cross self-locking block 331 and skid off from collude hanging groove.Therefore, from the above, this fixing device is easy to fixed installation and is easy to dismounting, the combustible gas detector difficult drop-off that is fixed and installs, the combustible gas detector installed of effectively preventing to be fixed tilts or comes off, and in the daily use of combustible gas detector, is easy to demolition and maintenance.
Figure 7 shows that the B-B cross-section separation structure schematic representation of structure shown in Figure 5.As can be seen from Figure 7, collude the upper surface of hanging pawl 22,23 and under the elastic force effect of shell fragment, be close to the upper surface that colludes hanging groove 33.
Under the situation that does not depart from spirit and scope of the present utility model, can also form other different mode of executions.The related technological scheme of the utility model should be not limited to the specific embodiment described in this specification.
