The seal plug that the present invention is arranged in spoke cap through hole has special tectonic: seal plug is made up of plug crown, plug sealing surface, plug groove, plug bayonet socket and plug tail cone.The plug tail cone of plug afterbody is designed to taper so that seal plug is installed in former spoke cap through hole; It is to occur obscission after seal plug is installed that plug bayonet socket external diameter is greater than spoke cap through hole internal diameter; Plug groove external diameter is suitable with former rim spoke cap through-hole diameter, to facilitate seal plug to be in place to guarantee seal plug to fix by plug groove and rim spoke cap through hole edge close contact simultaneously; Seal plug is installed in former rim spoke cap through hole, and plug sealing surface is pressed on rim wheel rim spoke cap through hole edge and forms sealing, makes the gas in tire cannot be to external leakage; The seal plug exposed visible part outside that is in place is plug crown, it mainly contains two functions: because plug crown is identical with plug sealing surface external diameter, and be greater than spoke cap through-hole diameter, make seal plug and rim wheel rim form annular seal space, the tire pressure that tyre inflating produces on the other hand further presses on plug sealing surface by plug crown, strengthen the pressure of seal plug and rim wheel rim contact surface, the sealing reliability of enhanced leaktightness plug.
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the inner tube free wheels associated components schematic diagram that the present invention forms.
Fig. 2 is seal plug constructional drawing of the present invention.
Fig. 3 is that seal plug section-drawing is not installed in spoke cap of the present invention through hole.
Fig. 4 is that spoke cap of the present invention through hole has been installed seal plug section-drawing.
Fig. 5, Fig. 6, Fig. 7 is seal plug detailed description of the invention section-drawing.
1 rim in figure, 2 spoke caps, 3 spokes, 4 flower-drum, 5 seal plugs, 6 plug bayonet sockets, 7 plug grooves, 8 plug tail cones, 9 plug crowns, 10 rim wheel rims, 11 spoke cap through holes, 12 embedded metal sheets, 13 plug sealing surfaces.
Rim 1 of the present invention, spoke cap 2, the mode that connects to form between spoke 3 and flower-drum 4 is identical with common wheels, it is characterized in that at each spoke cap through hole 11 of common rim wheel rim 10, seal plug 5 being installed forms complete seal chamber jointly with rim, thereby reach the seal request of inner tube free wheels to rim self.
Seal plug 5 is made up of plug crown 9, plug sealing surface 13, plug groove 7, plug bayonet socket 6 and plug tail cone 8.It is for the ease of seal plug 5 being installed in former spoke cap through hole 11 that the plug tail cone 8 of afterbody is designed to taper, it is for fear of occurring seal plug 5 phenomenon that gets loose after seal plug 5 is installed that plug bayonet socket 6 external diameters are greater than spoke cap through hole 11 internal diameters, plug groove 7 external diameters are suitable with former rim spoke cap through hole 11 diameters, facilitate seal plug 5 to be in place, and also guarantee that seal plug 5 fixes by plug groove 7 and rim spoke cap through hole 11 edge close contacts simultaneously, seal plug 5 is installed in former rim spoke cap through hole 11, and spoke cap through hole 11 edges that plug sealing surface 13 is pressed on rim wheel rim 10 form sealing, thereby makes the gas in tire cannot be to external leakage, after seal plug 5 is in place, be blocked pileum face 9 and rim wheel rim 10 blocks of the other parts of plug are invisible part, exposed visible part plug crown 9 mainly contains two functions: because plug crown 9 is identical with plug sealing surface 13 external diameters, and be greater than spoke cap through hole 11 diameters, can be along come off by force direction while making seal plug 5 be subject to tire pressure, the tire pressure that tyre inflating produces on the other hand further presses on plug sealing surface 13 by plug crown 9, the pressure of enhanced leaktightness plug 5 and rim wheel rim 10 contact surfaces, form self sealss effect, the sealing reliability of enhanced leaktightness plug 5.
By above transformation, at the interior spoke type band inner tube of a tyre wheels that seal plug 5 has been installed of former spoke cap through hole 11, self has possessed excellent sealing chamber, thereby no longer needs the inner tube of a tyre, becomes inner tube free wheels.
In concrete enforcement, seal plug 5 can be made as rubber with elastomeric material, can make its one-tenth fly butterfly (as shown in Figure 5) by appropriateness thickening plug crown 9 middle body thickness in order to strengthen compressive strength; As be used in high press nips, can, at plug crown 9 embedded metal sheet 12 hard materials such as grade, form soft outside but hard inside structure, further strengthen seal plug 5 compressive strength (as shown in Figure 6); Seal plug 5 commonalities of more than enumerating two kinds of modes are more intense, are conveniently used on the different rim of wheel rim radian, and being relatively applicable to the common rim of upgrading is that inner tube free rim is used; Can also select material relative rigidityes such as plastics to manufacture seal plug 5, plug sealing surface 13 forming shapes unanimously get final product (sealing surface becomes the arc identical with wheel rim as shown in Figure 7) with wheel rim 10 contact surface radians, this hard structured identical occasion of rim wheel rim radian that is relatively suitable for use in, as used on batch manufacturing.
