Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are some, but not all embodiments of the invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
As shown in fig. 1, the present invention provides a rail fastener 10, including: base plate 12, two bolts 14, two spring bars 16, two nuts 18, and two washers 20. Two bolts 14 are respectively connected to both ends of the base plate 12, two nuts 18 are respectively and correspondingly screwed to the two bolts 14, and two elastic strips 16 are respectively pressed against both ends of the base plate 12 by one nut 18 and one washer 20. It should be noted that the connection manner of the bolt 14 and the substrate 12 is well known to those skilled in the art, and it is within the ability of those skilled in the art to understand and implement the connection manner, and will not be described herein. Furthermore, the present invention provides a rail clip 10 that further includes a backing plate, gauge block, etc., but the present invention does not relate to the improvement of these accessories, so that these accessories are not further described.
In this embodiment, as shown in fig. 1-3, the bottom side of the spacer 20 is provided with a groove 202 that mates with the elastic strip 16. That is, the bottom side of the pad 20 is provided with a circular arc-shaped groove 202, and the top of the elastic strip 16 can be conformally embedded in the groove 202. When the nut 18 is tightened, the groove 202 presses the elastic strip 16, the elastic strip 16 rebounds upwards, the top of the elastic strip 16 is firmly embedded in the groove 202, and the elastic strip 16 applies pressure to the surface of the groove 202. When the pad 20 is subjected to vibration to rotate, the pad 20 must overcome a part of the force (e.g., a horizontal component of a part of the pressure) applied by the elastic strip 16 to the groove 202 and overcome the friction between the elastic strip 16 and the groove 202. Therefore, the rotation of the washer 20 is limited, and the anti-loose effect is good.
In this embodiment, as shown in FIG. 2, the washer 20 is circumferentially provided with a plurality of upper locking teeth 204 on the top side and the nut 18 is circumferentially provided with a plurality of lower locking teeth 182 on the bottom side. After the washer 20 and the spring bar 16 are installed, the nut 18 is installed to the T-bolt 14. When the nut 18 contacts the washer 20, the lower locking teeth 182 also contact the upper locking teeth 204. At this point, as the nut 18 is further tightened, the plurality of lower locking teeth 182 slidingly engage the plurality of upper locking teeth 204 (i.e., the plurality of lower locking teeth 182 slide along the surface of the plurality of upper locking teeth 204), and the upper locking teeth 204 do not jam against the lower locking teeth 182, so that the nut 18 may continue to rotate downward until the desired position is achieved (i.e., until the nut 18 is installed; of course, the installed nut 18 may continue to rotate downward). When the nut 18 is installed, the groove 202 presses the elastic strip 16, the elastic strip 16 rebounds upwards, the gasket 20 is always pressed against the nut 18, and the plurality of upper locking teeth 204 of the gasket 20 are correspondingly engaged with the plurality of lower locking teeth 182 of the nut 18. When the nut 18 is loosened, the nut 18 is rotated in an unscrewing direction, and the upper locking teeth 204 correspondingly block the unscrewing rotation of the lower locking teeth 182. Since the spring strip 16 is always pressed against the groove 202 of the washer 20 and the washer 20 is also always pressed against the nut 18, if the nut 18 is unscrewed, the nut 18 must overcome the jamming of the plurality of upper locking teeth 204, i.e., must overcome a portion of the force (e.g., a horizontal component of a portion of the pressure) applied by the spring strip 16 to the groove 202 and the friction between the spring strip 16 and the groove 202. Therefore, the loosening of the nut 18 is restricted, and the loosening prevention effect is excellent.
In the embodiment shown in fig. 1 to 3, the counterclockwise direction is a direction in which the nut 18 is tightened, and the clockwise direction is a direction in which the nut 18 is loosened. Of course, the present invention may be configured such that the clockwise direction is the screwing direction of the nut 18, and the counterclockwise direction is the unscrewing direction of the nut 18, as long as the upper locking teeth 204 of the gasket 20 and the lower locking teeth 182 of the nut 18 are adapted.
In one embodiment of the present invention, a magnetic material layer is disposed in the groove 202. The magnetic material will create an attractive force with the elastic strip 16 and the spacer 20 may be attached to the elastic strip 16. The attraction between each other facilitates the installation alignment of the groove 202 with the spring band 16 when the spacer 20 is installed. Moreover, the attraction between each other makes the relative movement between the washer 20 and the elastic strip 16 more difficult, and also helps to improve the anti-loosening capability. For example, when the nut 18 is loosened, the nut 18 is difficult to loosen because the nut 18 overcomes a portion of the force applied to the washer 20 by the spring bar 16, overcomes the friction between the spring bar 16 and the washer 20, and overcomes the attraction between the washer 20 and the spring bar 16.
In one embodiment of the present invention, a plurality of teeth are disposed in the recess 202. The teeth can increase the friction between the groove 202 and the elastic strip 16, so that the gasket 20 and the elastic strip 16 are more difficult to move relatively, and the anti-loosening capability is improved. That is, when the nut 18 is loosened, the nut 18 needs to overcome the greater frictional force between the spring bar 16 and the washer 20.
In one embodiment of the present invention, the groove 202 is provided with a frosted surface. The frosted surface can increase the friction between the groove 202 and the elastic strip 16, so that the gasket 20 and the elastic strip 16 are more difficult to move relatively, and the anti-loosening capability is improved. That is, when the nut 18 is loosened, the nut 18 needs to overcome the greater frictional force between the spring bar 16 and the washer 20.
As shown in fig. 2 and 3, in one embodiment of the present invention, a ring of flange 206 is provided on the inner side of the washer 20, the flange 206 is in contact with the inner side of the nut 18, and the outer surface of the flange 206 is provided with a frosted surface. In the present embodiment, the flange 206 is inserted into the inner side of the nut 18, and the frosted surface is in contact with the inner side of the nut 18, so that the friction between the washer 20 and the nut 18 is increased, which helps to improve the anti-loosening capability.
In one embodiment of the invention, the bottom of the inside of the nut 18 is provided with a frosted surface. This frosted surface contacts the flange 206 of the washer 20, so that the friction between the washer 20 and the nut 18 is increased, contributing to the anti-loosening capability.
In one embodiment of the present invention, the number of the upper locking teeth 204 is 16-20, and the lower locking teeth 182 correspond to the number of the upper locking teeth 204. The upper locking teeth 204 and the lower locking teeth 182 within the number range have good anti-loosening effect and are convenient to process and manufacture.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
