Abstract
The invention provides a rim spoke fastening device, which comprises a rim (1), a screw head (2) and a spoke (6). A spoke hole (3) for installing the screw head (2) is formed in the rim (1). A threaded hole for installing and fixing the spoke (6) is formed in the screw head (2). A thread A (7) is arranged on the inner ring of the threaded hole. A thread B (5) is arranged on the outer ring of the screw head (2) at the part exceeding the rim (1). The directions of the thread B (5) and the thread A (7) are opposite. A nut (4) is always in close fit with the rim (1). When the screw head (2) and the spoke (6) are loosened, the connection between the screw head (2) and the nut (4) becomes tighter and tighter. In the process that the screw head (2) is loosened, the nut (4) is always in close fit with the rim (1) with the change of the screw head (2). Therefore, the screw head (2) is effectively prevented from being loosened, the service life of a wheel assembly is improved, the spoke is convenient to replace and the service life of the screw head is prolonged.
Description
Technical field
The present invention relates to a kind of rim, relate in particular to a kind of rim spoke securing device.
Background technology
Present stage, after conventional bicycle, the assembling of motor bike rim, in long motion process, spiral shell head and spoke can be more and more loosening, often need the degree of tightness of adjustment spiral shell head and the beat of wheels, at present a lot of producers are devoted to research always and how prevent that spiral shell head from becoming flexible technology, and existing technology is in the tapped bore the inside of spiral shell head, to add glue to prevent that spiral shell head and spoke from becoming flexible, but glue has following shortcoming: cost effect higher, that maintain is not long, and after a period of time, glue will lose efficacy; Dismounting is inconvenient, if steel wire fracture, customer can not add glue in the own tapped bore at spiral shell head the inside, and assembles after dismounting again, and the glue of the inside has just lost former producing effect, and glue can only disposablely be used; Existing common spiral shell head is connected with spoke, and through motion for a long time, spiral shell head and spoke are loosening, produce gap, and in use, water and dirt can enter in rim in gap, affect the normal use of rim.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of firmly tight, easy-to-dismount rim spoke securing device, comprise rim, spiral shell head and spoke, rim is provided with for the spoke hole of spiral shell head is installed, described spiral shell head inside is provided with one, for spoke, fixing tapped bore is installed, described tapped bore inner ring is provided with screw thread A, the Luo Tou outer ring, position that described spiral shell head exceeds rim is provided with screw thread B, the opposite direction of described screw thread B and screw thread A, also be provided with a nut, described nut is tightened in Luo Toushang by screw thread B, and described nut pushes against rim away from one end of rim center.
Beneficial effect of the present invention: bicycle is due to long-time use, spiral shell head can become flexible, and this rim spoke securing device is at spiral shell head outer lock upper cap nut, and because the screw thread B that is provided with of spiral shell head outside and its inside be provided with for the screw thread A opposite direction of spoke is installed, nut can fit snugly on rim all the time, like this, when the connection between spiral shell head and spoke is become flexible, connection between spiral shell head and nut is more and more tighter, in the loosening process of spiral shell head, nut can closely cooperate with rim all the time along with the variation of spiral shell head, can effectively prevent that spiral shell head is loosening, promote wheels service life, the replacing of spoke is convenient, extend the service life of spiral shell head.
Accompanying drawing explanation
Fig. 1 is decomposing state schematic diagram of the present invention;
Fig. 2 is the cutaway view of spiral shell head in Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, spiral shell head 2 is inserted in the spoke hole 3 of rim 1 inside, nut 4 is gently twisted along the hand of spiral of screw thread B5, spoke 6 is inserted in spiral shell head 2, use screwdriver to twist spiral shell head 2 along hand of spiral on spoke 6, make spiral shell head 2 and spoke 6 reach fastening, the nearlyer step of nut 4 is tightened, can complete assembling.The material of described nut 4, spiral shell head 2 is aluminum alloy.
