Abstract
A connecting structure of a collector device and a casing lateral plate of a centrifugal ventilator comprises the collector device (1) and a casing front lateral plate (2). A bolt installing hole (6) is arranged on the collector device (1), a rectangular nut cutting ferrule installing hole (3) is arranged on the casing front lateral plate (2), the nut (4) is installed in a nut cutting ferrule (5), and the nut cutting ferrule (5) is installed on the casing front lateral plate (2) through the nut cutting ferrule installing hole (3). Due to the fact that the nut cutting ferrule is installed on the casing front lateral plate through the nut cutting ferrule installing hole, the casing lateral plate is not required to be welded and has no welding deformation and welding stress. Due to the fact that the nut cutting ferrule can move in the rectangular nut cutting ferrule installing hole, the adjustment can be performed in the assembling process according to actual errors, the adjustment range is large, the radial size of an opening is easily ensured, and the assembling requirements are met.
Description
Technical field
The utility model relates to the linkage structure between a kind of centrifugal blower slip ring and the housing side wall.
Background technique
At present, being connected between centrifugal blower slip ring and the housing side wall mainly contains dual mode: the one, weld a stiffening ring at the back at the casing front side plate, and the tapping together of side plate and stiffening ring is connected slip ring fixing with bolt then with housing side wall.Radially contain a mouthful size for what adjust slip ring and impeller, the diameter of slip ring upper bolt hole is bigger than the diameter in the hole on side plate and the stiffening ring, can contain a mouthful size through moving slip ring adjustment like this.Another kind of Placement is at casing front side plate back spot welding nut, slip ring to be connected fixing with housing side wall with bolt.Equally, radially contain a mouthful size for what adjust slip ring and impeller, the diameter of slip ring upper bolt hole is bigger than the diameter in the hole on side plate and the stiffening ring, can contain a mouthful size through moving slip ring adjustment like this.Because housing side wall welding stiffening ring or electric welding nut all can cause housing side wall because of welding deformation, make the housing side wall out-of-flatness.In addition, owing to receive the restriction of slip ring upper bolt hole diameter, the adjustment range and the surplus that contain mouthful size are limited, can not satisfy the assembling demand.And after the stripped thread corrosion occurring, maintain and replace is extremely inconvenient.
The model utility content
For solve housing side wall in the existing technology because of welding deformation become out-of-flatness, contain the technical problem that adjustment range is little and maintain and replace is inconvenient of mouthful size; The purpose of the utility model is to provide the linkage structure of a kind of centrifugal blower slip ring and housing side wall; The housing side wall of this linkage structure does not need welding; Therefore housing side wall can not be out of shape; And adopt this linkage structure can make the adjustment range that contains mouthful size big, satisfy the assembling demand, repair and replacement very easily after the stripped thread corrosion appears in screw bolt and nut.
To achieve these goals, the utility model provides the linkage structure of a kind of centrifugal blower slip ring and housing side wall, the first aspect according to the utility model comprises slip ring, and it is provided with bolt mounting holes; The casing front side plate is characterized in that, has rectangular nut cutting ferrule mounting hole on the said casing front side plate, and nut is installed in the nut cutting ferrule, and the nut cutting ferrule is installed on the casing front side plate through nut cutting ferrule mounting hole.
The second aspect of the utility model, on the basis of first aspect, the both sides of said nut cutting ferrule are provided with the nut shoulder block, leave the gap between nut and the nut shoulder block.
The third aspect of the utility model, first or the basis of second aspect on, said nut cutting ferrule is to adopt Stainless Sheet Steel to process.
According to the utility model first aspect, can obtain following effect: because the nut cutting ferrule is installed on the casing front side plate through nut cutting ferrule mounting hole, housing side wall does not need welding, so housing side wall can not produce welding deformation and welding stress; Because the nut cutting ferrule can move in rectangular mounting hole, therefore in assembly process, can adjust according to the error of reality, adjustment range is big, is easy to guarantee to contain bore to size, has satisfied the assembling demand; After the stripped thread corrosion appears in screw bolt and nut, can change nuts and bolt very easily, maintenance easily.
According to the utility model second aspect,, made things convenient for the cooperation of screw bolt and nut to install owing to leave the gap between nut and the nut shoulder block.
According to the utility model third aspect, the nut cutting ferrule that adopts Stainless Sheet Steel to process, toughness and intensity are high, have satisfied installation requirement.

5: the nut cutting ferrule; 6: bolt mounting holes; 7: the nut shoulder block.
Embodiment
Below, describe with reference to the embodiment of accompanying drawing 1-6 the utility model:
Like figure, 1-6 is last to have rectangular nut cutting ferrule mounting hole 3, and nut 4 is installed in the nut cutting ferrule 5, and nut cutting ferrule 5 is installed in 3 li of rectangular nut cutting ferrule mounting holes, and can in mounting hole, move.
When mounted, owing between nut 4 and the nut shoulder block 7 certain clearance is arranged, therefore after bolt is through bolt mounting holes 6 and nut cutting ferrule mounting hole 3, be easy to be connected with nut 4.Then, travelling nut cutting ferrule 5 in nut cutting ferrule mounting hole 3 meets the requirements with mouthful dimension delta that radially contains of adjusting slip ring and impeller.
Claims (3)
1. the linkage structure of centrifugal blower slip ring and housing side wall comprises slip ring (1), and it is provided with bolt mounting holes (6); Casing front side plate (2); It is characterized in that; Have rectangular nut cutting ferrule mounting hole (3) on the said casing front side plate (2), nut (4) is installed in the nut cutting ferrule (5), and nut cutting ferrule (5) is installed on the casing front side plate (2) through nut cutting ferrule mounting hole (3).
2. the linkage structure of centrifugal blower slip ring according to claim 1 and housing side wall is characterized in that, the both sides of said nut cutting ferrule (5) are provided with nut shoulder block (7), leaves the gap between nut (4) and the nut shoulder block (7).
