Abstract
The utility model discloses a T-bolt with antiskid teeth. The T-bolt comprises a bolt head portion in a stick shape and a screw rod, the bolt head portion and the screw rod are in a T shape, the antiskid teeth are arranged on the side end face of the screw rod on the bolt head portion, and a groove is formed in the end face of the screw rod. The antiskid teeth protrude out of the side end face of the screw rod on the bolt head portion, the antiskid teeth are strip-shaped teeth or cobwebbing teeth, and the section of each antiskid tooth is triangular. The groove is a linear groove and/or hexagonal groove and the like with the circle center of the end face of the screw rod as a center. The T-bolt with the antiskid teeth is adopted, the T-bolt can be inserted into a T-groove fast, connection can be reliable, and the bolt does not rotate along with a nut in the process of screwing the nut.
Description
Technical field
The utility model relates to a kind of bolt, relates in particular to a kind of T-shaped bolt.
Background technique
Common T-shaped bolt, bolt head is rectangular, screw portion becomes T font with bolt head, the width of head is less than the open part width of T-shaped groove, so that the head of T-shaped bolt can insert in T-shaped groove, while needing fixation workpiece from the arbitrary position of T-shaped slot length direction, by T-shaped bolt 90-degree rotation, make the length direction of its head vertical with T-shaped groove, hook the inner side of T-shaped channel opening part, by tightening the nut being screwed on T-shaped bolt screw rod, workpiece is fixed.The T-shaped bolt of this structure can make bolt be connected fast with basic part easily, obtain applying more widely, but part also comes with some shortcomings, because T-shaped bolt head and the area of contact inside T-shaped channel opening part of this form are too little, surface friction drag is corresponding less, and the easy transfer of bolt in fastening nut process on the one hand, tends in the using process after tightening on the other hand due to the impact that is subject to external force or vibrations, cause bolt easily loosening, thereby cause the unreliable of connection.
Model utility content
For the existing above-mentioned deficiency of prior art, technical problem to be solved in the utility model is to provide a kind of T-shaped bolt with slideproof tooth, it can not only the T-shaped groove of quick insertion in, and guarantee to connect reliable, not transfer of bolt in the process of fastening nut.
In order to solve the problems of the technologies described above, a kind of T-shaped bolt with slideproof tooth of the present utility model, comprises bolt head and screw rod, and this bolt head and screw rod form T character form structure, on described bolt head, screw rod side end face is provided with slideproof tooth, and screw rod end face is provided with groove.
In said structure, due to bolt head and screw rod shape in T shape, bolt head is stick shape, therefore the width of bolt head is suitable with T-shaped groove, in use can insert T-shaped groove from arbitrary position, after 90-degree rotation, the length direction of bolt head hooks the inner side of T-shaped channel opening, again because screw rod side end face on bolt head is provided with slideproof tooth, be that the slideproof tooth that the screw rod side end face on bolt head arranges contacts with the inner side of T-shaped channel opening, when fastening nut is by workpiece fixedly time, existence due to slideproof tooth, surface friction drag increases, slideproof tooth also can embed in the surface of contact on T-shaped groove under the effect of screwing force, even if meet larger vibrations in working procedure, T-shaped bolt can not produce displacement yet, guaranteed the reliability connecting, because screw rod end face is provided with groove, at the initial stage of fastening nut, can use corresponding tool, by this groove, T-shaped bolt is stable in to needed position again, eliminate the possibility of bolt transfer.
A kind of preferred implementation of the present utility model, described slideproof tooth protrudes from screw rod side end face on bolt head, and this slideproof tooth is bar shaped tooth or reticulate pattern tooth, and its cross section is triangle.Adopt this mode of execution, because slideproof tooth protrudes from screw rod side end face on bolt head, when increasing frictional force, can guarantee can embed in the surface of contact on T-shaped groove under the effect of slideproof tooth at screwing force, guarantee to connect reliable, again because slideproof tooth is bar shaped tooth or reticulate pattern tooth, its cross section is triangle, therefore its profile of tooth is sharp-pointed, can guarantee the embedding effect to T-shaped groove surface of contact.
Another kind of preferred implementation of the present utility model, described groove is in-line groove and/or the hex shaped groove centered by the screw rod end face center of circle.Adopt this mode of execution, can use easily straight screwdriver or inner hexagon spanner, at the initial stage of fastening nut, T-shaped bolt is stable in to needed position, eliminated the possibility of bolt transfer, and in-line groove more there is the effect of the bolt head of sign T word shape.
Another preferred implementation of the present utility model, the bolt head of described in-line groove and stick shape is perpendicular or parallel, and described hex shaped groove has the bolt head of a pair of side and stick shape perpendicular or parallel.Adopt this mode of execution, can according to the circumferential position of screw rod end face in-line groove or hex shaped groove, accurately judge the relative position of T-shaped bolt head and T-shaped groove easily, guarantee that bolt head length direction is vertical with T-shaped slot length direction, thereby guarantee to connect effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the T-shaped bolt of the utility model band slideproof tooth is described in further detail.
Fig. 1 is the structural representation of a kind of embodiment of T-shaped bolt of the utility model band slideproof tooth.
In figure: 1-bolt head, 2-slideproof tooth, 3-screw rod, 4-groove.
Embodiment
In the T-shaped bolt with slideproof tooth shown in Fig. 1, bolt head 1 is cuboid, be T set up of character patt ern with screw rod 3, bolt head 1 width is identical with screw rod 3 diameters or slightly large, in the length of bolt head 1, all protrude outside screw rod 3 at two ends, bolt head 1 short transverse is the axial of screw rod 3, in bolt head 1 short transverse, screw rod side end face is provided with slideproof tooth 2, slideproof tooth 2 bolt head 1 length direction protrude outside screw rod 3 part have setting, and protrude from the screw rod side end face of bolt head 1, slideproof tooth 2 is bar shaped tooth, along bolt head width direction, be equally spaced, slideproof tooth 2 cross sections are triangle.
End face at screw rod 3 is provided with groove 4, and groove 4 is symmetrical centered by the screw rod 3 end face centers of circle, and it is shaped as in-line groove stack hex shaped groove, has so both gone for Flathead screwdriver, also goes for inner hexagon spanner; In-line groove length direction is parallel with bolt head 1 length direction, and in hex shaped groove, a pair of side is parallel with bolt head 1 length direction.
Being only to have listed a kind of preferred implementation of the present utility model, but the utility model is not limited to this, can also make a lot of improvement and conversion, as, the shape of described bolt head 1 can not be also cuboid, but bolt axis to end face on parallelogram or the strip and block body of rectangular to shapes such as rounding of angle; Described slideproof tooth 2 can be also reticulate pattern tooth; Described groove 4 can be also in-line groove or the hex shaped groove arranging separately, can also be cross recess.And so on, as long as without prejudice to basic principle of the present utility model, all should fall in protection domain of the present utility model.
