Description
The utility model relates to a kind of collapsible rim.
Wheel has two types usually, and a kind of is groove type, and another kind is half groove type.Groove type is used for all cars and light-duty truck, and half groove type only is used for relatively large multilayer tire or long-distance truck usually.Half groove type wheel has the outside wheel rim of detouchable, and it is easy to install, and can bear higher tire pressure, yet, surpassing six layers, the too high tire of limit tooth, its tyre bead is extremely hard, in the integral type wheel that wants to pack into and not damage tyre bead just very difficult.Thereby wheel rim and the spoke thereof of forming wheel just seem particularly important.
The purpose of this utility model provides a kind of collapsible rim, and this collapsible rim helps the installation and the dismounting of wheel, not fragile again tire.
The purpose of this utility model is achieved in that
Fig. 1 is the relative mounting positions figure of the utility model wheel rim and protector.
Fig. 2 is the interior buckle closure structural representation that the utility model adopts.
Fig. 3 is the outer buckle closure structural representation that the utility model adopts.
Fig. 4 is the structural representation of the locking screw rod of the utility model employing.
Fig. 5 is the left view of Fig. 4 along the B-B line.
Fig. 6 is the utility model jam nut structural representation.
Fig. 7 is the left pseudosection of Fig. 6 along the C-C line.
Fig. 8 is the structural representation of a kind of check washer of the utility model employing.
Shown in Fig. 1-8; wheel rim of the present utility model is fastened by two and half wheel rims and forms; fasten relatively easily in order to make; two and half wheel rim contact-making surfaces are certain taper; can be provided with resilient protection device 2 in tooth 1 inboard, wheel rim both sides; tire 3 tyre beads are installed between rim bead tooth 1 and the protector 2; establish axis hole 6 at the wheel rim center; evenly offer on axis hole 6 exterior periphery fixing in; the screw hole 5 of outer buckle closure; on wheel rim, be provided with the fixing hole 4 of fixing two and half wheel rims along circumference; outer buckle closure is by base 7; end socket 8 and screw hole 9 form, and screw hole is opened on the base, and it is coniform that end socket is. The anti-loosening screw that the utility model adopts is provided with arrow groove 10, one Spring Card is located in the jam nut, Spring Card 11 overheads are in nut on the tooth, there is a projection at check washer 12 middle parts, can probe in the arrow groove 10, offer spring pushing hole 13 and mesopore 14 at jam nut, spring pushing hole 13 makes Spring Card 11 break away from the card tooth when being used for dismounting.
The utility model is easy for installation, and detaching tyre is very easy to, and the tire that can avoid the metal current sled to press causing and the deformed damaged of wheel rim are conducive to promote the use of.
The resilient protection device that the utility model cooperates with wheel rim can make when tire is unexpected exits, and protects inside and outside tire, and can make vehicle continue to travel.
