Abstract
The utility model discloses a high strength impeller for vehicle, including impeller body and impeller center pin, the surface of the trailing end of impeller center pin is provided with screw thread portion and the screw thread dish of cooperation in screw thread portion, that one side of screw thread dish towards the impeller body is provided with the rubber layer and is used for providing elastic thrust to the impeller body. Compared with the prior art, the utility model, through the setting on thread disc and rubber layer, utilize the elastic force effect that the rubber layer gave the impeller body for impeller body and impeller center pin can keep closely laminating, have guaranteed the continuous joint strength at impeller body and impeller center, prevent that the impeller body from taking place radially or the axial runout, and the result of use of impeller has obtained effective guarantee.
Description
Technical Field
The utility model relates to a vehicle accessory technical field, concretely relates to high strength impeller for vehicle.
Background
The impeller is one of the common accessories in the vehicle, the connection of its impeller body of current impeller and impeller center pin divide into two kinds of dead connection and swing joint, the dead connection generally adopts the welded mode, this kind of mode is though joint strength between them is great, but be difficult to carry out convenient dismantlement, be unfavorable for the maintenance and the maintenance of impeller, swing joint utilizes connecting tool, for example bolt, bayonet lock etc. even this kind of mode is convenient for dismantle, but the general joint strength of current connected mode is lower, the impeller is in long-time use, radial or axial runout takes place easily for the impeller body, just lost the compactness between impeller body and the impeller center pin like this, lead to the rotatory unstability of impeller body, influence the result of use.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects in the prior art, the high-strength impeller for the vehicle is provided, which can ensure the continuous connection strength of the impeller body and the central shaft of the impeller.
The technical scheme is as follows: in order to achieve the above object, the present invention provides a high strength impeller for vehicle, including impeller body and impeller center pin, the surface of the trailing end of impeller center pin is provided with screw thread portion and the screw thread dish of cooperation on screw thread portion, the screw thread dish is provided with the rubber layer towards that side of impeller body and is used for providing elastic thrust to the impeller body.
Furthermore, the butt joint ends of the impeller central shaft and the impeller body are respectively provided with a positioning groove and a positioning block which are matched with each other, the positioning groove and the positioning block not only can provide a positioning function in installation, but also can improve the connection strength of the impeller central shaft and the impeller body, so that the impeller central shaft can drive the impeller body to rotate better.
Furthermore, the constant head tank is ring groove structure and coaxial the seting up on the impeller center pin.
Further, the outer edge of the threaded part does not exceed the outer edge of the central shaft of the impeller, so that the threaded part is prevented from influencing the installation of the central shaft of the impeller.
Has the advantages that: compared with the prior art, the utility model, through the setting on thread disc and rubber layer, utilize the elastic force effect that the rubber layer gave the impeller body for impeller body and impeller center pin can keep closely laminating, have guaranteed the continuous joint strength at impeller body and impeller center, prevent that the impeller body from taking place radially or the axial runout, and the result of use of impeller has obtained effective guarantee.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.
As shown in fig. 1, the utility model provides a high strength impeller for vehicle, including impeller body 1 and impeller center pin 2, the surface of impeller center pin 2's trailing end is provided with screw thread portion 4 and the screw thread dish 5 of cooperation on screw thread portion 4, screw thread dish 5 is provided with rubber layer 6 towards that one side of impeller body 1, the outer edge that screw thread portion 4 does not surpass impeller center pin 2 follows outward, impeller center pin 2 and the butt joint end of impeller body 1 are provided with constant head tank 8 and the locating piece 7 of mutual matching respectively, constant head tank 8 is ring groove structure and coaxial seting up on impeller center pin 2, locating piece 7 also can just in time be just in the card for the ring structure and join in marriage in constant head tank 8.
In the installation process of the high-strength impeller for the vehicle, the impeller body 1 is firstly sleeved on the impeller central shaft 2, the positioning block 7 is clamped in the positioning groove 8, then the threaded disc 5 is installed on the threaded part 4, and the rubber layer 6 on the threaded disc 5 is completely attached to the impeller body 1 along the threaded part 4 until the threaded disc 5 can not rotate basically.
In the embodiment, when the high-strength impeller is used, the rubber layer 6 continuously gives elastic thrust to the impeller body 1, so that the impeller body 1 is tightly attached to the impeller central shaft 2, the impeller body 1 is prevented from jumping radially or axially, and the use effect of the impeller is effectively guaranteed.
Claims (4)
1. The utility model provides a high strength impeller for vehicle, includes impeller body and impeller center pin, its characterized in that: the surface of the tail end of the central shaft of the impeller is provided with a threaded part and a threaded disc matched with the threaded part, and the side, facing the impeller body, of the threaded disc is provided with a rubber layer for providing elastic thrust for the impeller body.
