The specific embodiment
Now in conjunction with the accompanying drawings, the present invention is further described, and the name of sequence number is called among the figure: the first frame bar 1, right angled triangle inside casing 101, long limit 102, socket 103, installing port 104, seal groove 2, T-slot 3, the second frame bar 4, right-angled trapezium inside casing 401, minor face 402, total seal groove 5, H shape groove 6, check lock lever 7, inner fovea part 701, push against piece 702, projection 8, groove 9, two logical connection straps 10, framework 11, installing hole 1101, box-shaped case 12, plug 1201.
As shown in Figure 1 and Figure 2, this air-conditioning draught fan box body combinations locking device comprises frame bar, sealing strip, check lock lever 7, the frame bar comprises the first frame bar 1, the second frame bar 4, the first frame bar is to be made of right angled triangle inside casing 101 and long limit 102, and the second frame bar is to be made of right-angled trapezium inside casing 401 and minor face 402.The first frame bar, the second frame bar are equipped with the inclined plane, be equipped with T-slot 3 on inclined plane separately and place two seal grooves 2 of T-slot both sides, shown in Fig. 3～5, inclined plane by the first frame bar cooperates with the inclined plane of the second frame bar, or the inclined plane of two first frame bars cooperates, constitute H shape groove 6 by the T-slot on two inclined planes, constitute two total seal grooves 5 by the seal groove on two inclined planes.Need with the first frame bar and the second frame bar be fastening or two first frame bars when fastening, only need in total seal groove of above-mentioned formation, sealing strip is installed, in H shape groove, insert a check lock lever 7 that is H shape and can finish the fastening of two frame bars.
As Fig. 6～shown in Figure 8, in order further to improve two stability and firmness after the combination of frame bar, on the inclined plane of the first frame bar, the second frame bar, be provided with projection 8 and groove 9, cooperate with groove, projection on the another side moulding respectively by the projection on the frame bar, groove, thereby effectively prevent to cause the connection of two frame bars loosening, guaranteed stability of structure and firmness because of check lock lever is loosening; In addition, as shown in Figure 9, be provided with at check lock lever inner fovea part 701 and push against piece 702, also can prevent that check lock lever is loosening.
Said structure is the setting of the relevant frame bar of the present invention, and the frame bar constitutes the structure of frame.Now in conjunction with said structure and accompanying drawing 10～Figure 13, the present invention is constituted casing to be further described: Figure 10 is the combining structure schematic diagram that the frame bar constitutes panel frame, as seen from the figure, frame bar two ends are provided with the oblique section, be orthogonal structure to adapt to the combination of frame bar, the oblique section is provided with socket 103, connect two rectangular logical connection straps 10 by socket between the two adjacent edge mouldings, connect from beginning to end by this kind mode by four frame bars and promptly to constitute panel frame, by six such panel frames, pass through sealing strip between the two adjacent surface plate frameworks, check lock lever is connected and fixed, and promptly constitutes the framework 11 of air-conditioning draught fan casing.Because the air-conditioning draught fan casing is when reality is used, it is uncovered that a face is arranged, be used for the air-out of air-conditioning draught fan, so outlet air surface and other face of air-conditioning draught fan casing are provided with different, as Figure 11～shown in Figure 12, Figure 11 is the structural representation of one jiao of casing outlet air surface, Figure 12 is the structural representation of one jiao in other face of casing, concrete structure is: by the first frame bar, the second frame bar passes through check lock lever, sealing strip connects and composes the frame of outlet air surface, pass through check lock lever between any two by the first frame bar, sealing strip constitutes the frame of other faces, and above-mentioned frame connects the framework that two logical connection straps promptly constitute the air-conditioning draught fan casing by socket between any two.
In order to reach the comparatively firm purpose of Fast Installation, structure, a kind of method of air-conditioning draught fan box body combinations locking is now proposed, be specially: at first, connect and compose a panel frame by four frame bars from beginning to end by two logical connection straps, at this moment, the socket of connection strap and oblique section is a matched in clearance, so combination is comparatively convenient and strength-saving, for connection strap and socket are connected firmly, carry out mechanical stamping in the socket outside, make to be interference fit with connection strap after the socket crimp, to reach fixedly connected purpose.Also two logical connection strap surfaces can be provided with fricting strip in addition, with further raising bonding strength.In the same manner described above, obtain all the other five panel frames of air-conditioning draught fan casing, then resulting six panel frames are connected and fixed by check lock lever, sealing strip between any two, promptly constitute the framework of air-conditioning draught fan casing.The sequencing that is connected with owing to panel frame, so the insertion of check lock lever operation also divides sequencing, the number that is connected with panel frame along with panel frame increases, the direction of insertion of check lock lever is limited, so corresponding installing hole need be set at the drift angle of panel frame, this installing hole is actually by on the oblique section of frame bar end installing port being set, and forms installing hole after two frame bar combinations, and the purpose of installing hole promptly makes things convenient for the insertion operation of check lock lever.As shown in figure 13,, influenced the outward appearance of casing,, can play the coverage installing hole, to reach purpose comparatively attractive in appearance so hide in one jiao of casing by the box-shaped case of band plug because installing hole is set.
