Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The utility model discloses a cigarette machine shell assembly structure, as shown in fig. 1 to fig. 3, including well casing 1, the left and right sides of well casing 1 respectively is equipped with curb plate 2, and curb plate 2 and well casing 1 enclose into the installation cavity 900 that is used for the holding fan, and wherein, the air outlet can set up at the top of well casing 1, and the front side and the downside of installation cavity 900 can correspond and be equipped with the worry oil net.

As shown in fig. 9 and 10, the middle shell 1 includes a middle shell edge portion 11, the middle shell edge portion 11 is formed with a notch 101, a clamping plate 111 is formed in the notch 101, an inner end of the clamping plate 111 (i.e. an end of the clamping plate 11 relatively far away from the edge of the middle shell 1) is integrally connected with a notch bottom edge 1011 of the notch 101, as shown in fig. 11, a slot 1100 is formed between the clamping plate 111 and the middle shell edge portion 11, and a fastening hole 110 is formed on the clamping plate 111. The structure of the clamping plate 111 can be manufactured by a stamping process of the prior art. As shown in fig. 7 and 8, the side panel 2 includes a side panel edge 20, the side panel edge 20 is connected with a folded edge plate 21, the folded edge plate 21 is formed by bending the side panel 2 by 90 ° on the basis of the body of the side panel 2, an opening 210 is formed on the folded edge plate 21, a barbed plate 211 is formed in the opening 210, a hook root end 2111 is formed at one end of the barbed plate 211, a hook head end 2112 is formed at the other end corresponding to the barbed plate 211, and the hook root end 2111 and the edge of the opening 210 are integrally connected, or it can be understood that the end of the barbed plate 211 relatively close to the side panel edge 20 is the hook head end 2112, so that the barbed plate 211 forms a barbed shape. As shown in fig. 2, 4 and 6, the folding plate 21 is inserted into the corresponding slot 1100, the barb plate 211 is disposed in the corresponding fastening hole 110, and the hook head 2112 fastens the edge of the fastening hole 110.

When the side plate 2 is assembled with the middle housing 1, the hook plate 211 is aligned with the corresponding buckle hole 110, as shown in fig. 5, and then the folded plate 21 is inserted into the slot 1100, during this process, the outer end of the clamping plate 111 contacts with the hook root end 2111, the hook plate 211 gradually expands the slot 1100, that is, the clamping plate 111 elastically deforms and swings downward, and simultaneously, the hook plate 211 elastically deforms and retracts inward (that is, the hook head end 2112 elastically swings toward the buckle hole 110), and then, as shown in fig. 6, when the hook head end 2112 slides into the buckle hole 110, the hook plate 211 and the clamping plate 111 elastically deform and recover, so that the folded plate 21 is clamped between the middle housing edge 11 and the clamping plate 111, and the hook head end 2112 abuts against the edge of the buckle hole 110, in the state shown in fig. 6, when the side plate 2 is pulled away from the middle housing 1, the hook head end 2112 is blocked by the edge of the buckle hole 110, so as to avoid the release, because the inner end of the notch of the clamping plate 111 is connected with the notch 101, and the notch of the side plate 111 is connected as to form a solid structure, so that the inner end of the side plate 21 is firmly fixed to the side plate 1, and the side plate 21 is inserted into the side housing 1100, and the side plate is firmly fixed to form a side plate 1, so that the folded plate 21 is firmly fixed to the side plate 21. Because the utility model discloses a cigarette machine shell assembly structure has adopted the above buckle formula assembly structure, so the utility model discloses a cigarette machine shell assembly structure avoids need adopting screw or rivet assembly, but only just can make curb plate 2 and well casing 1 assemble through simple direct well insert operation, then the utility model discloses be favorable to improving assembly efficiency. As shown in fig. 1, the side plates 2 located on the left and right sides of the middle case 1 are in a left-right symmetrical relationship with each other.

Further, as shown in fig. 10 and 11, the outer end of the clamping plate 111 is formed with a guide lip 1111 for guiding the folding plate 21 to slide into the slot 1100, and the guide lip 1111 forms an acute angle with the middle shell edge 11 (i.e. an angle dimension "X" shown in fig. 11, which may be set to 40 ° to 50 °), as shown in fig. 5, when the folding plate 21 is inserted into the slot 1100, if the folding plate 21 is inclined with respect to the slot 1100, the edge of the folding plate 21 first contacts the guide lip 1111, and the folding plate 21 is gradually swung and displaced to align with the slot 1100 by the guiding action of the guide lip 1111, so that a certain assembling operation error can be allowed, which is beneficial to improving the assembling efficiency.

Further, as shown in fig. 11, an entrance guide fillet 1112 is formed at a connection position of the guide lip 1111 and the clamping plate 111, that is, the entrance guide fillet 1112 is located at an entrance of the insertion groove 1100, so that the entrance of the insertion groove 1100 is formed in a gradually narrowing form, which is beneficial to the easy insertion of the hemming plate 21 into the insertion groove 1100.

Further, as shown in fig. 10, the fastening hole 110 is configured as a rectangular hole, as shown in fig. 8, the barb plate 211 is configured as a rectangular plate, so that, as shown in fig. 4, it is advantageous to make the hook end 2112 in line contact with the edge of the fastening hole 110, and when the folded plate 21 swings in a plane parallel to the folded plate 21 relative to the middle case 1, since the hook end 2112 is in line contact with the edge of the fastening hole 110, the edge of the fastening hole 110 acts as a better barrier to the swing of the hook end 2112, so that the assembly of the side plate 2 and the middle case 1 is more stable.

Further, as shown in fig. 9, the middle case 1 includes a top plate 1001 and a back plate 1002, the rear end of the top plate 1001 is integrally connected with the upper end of the back plate 1002, that is, the middle case 1 can be made by bending a whole steel plate, the clamping plates 111 are distributed on the top plate 1001 and the back plate 1002, specifically, the left end and the right end of the top plate 1001 are respectively provided with two clamping plates 111, the left end and the right end of the back plate 1002 are respectively provided with two clamping plates 111, as shown in fig. 1, the side plate 2 is fastened with the top plate 1001 and the back plate 1002 at the same time, so that the installation cavity 900 is formed with a simple structure, and the middle case 1 and the side plate 2 are also stably assembled.
