Abstract
The utility model relates to a kind of Anti-swivel bolt structure, includes wheel hub and bolt; Described wheel hub is provided through the bolt hole of bolt; Described bolt hole inwall is provided with at least one groove along the axis of bolt hole; The bolt shank that described bolt includes bolt head and is connected with bolt head; The end side surface that described bolt is relative with bolt head is provided with screw thread; Described bolt shank is provided with at least one axial projection structure close to one end of bolt head; The quantity of described protruding structure and shape all with described fit depressions.By the technical program, when wheel hub coordinates with bolt, the protruding structure on bolt and the groove fit on wheel hub, when needs detaching tyre, only need use spanner nut can be unclamped; When bolt needs to change, namely can change as long as take off bolt, and need not wheel hub be changed.
Description
Technical field
The utility model belongs to fastener areas, specifically refers to a kind of Anti-swivel bolt structure on automotive hub.
Background technique
Bolt on automotive hub is used for being fastenedly connected with wheel, and tire belongs to and easily damages part, in the using process of vehicle, needs repeatedly to be pulled down by tire from wheel hub, at this moment just needs to carry out loosening repeatedly to bolt.And, wheel hub structure is because the relation of break, bolt not easily takes off from wheel hub, and in unloading process, need to use spanner to assist, in order to prevent in unloading process to the head of bolt, to the infringement of bolt head, existing technology adopts mode bolt being pressed into the bolt hole on wheel hub, makes the mode fixing bolt of bolt and wheel hub interference fit, as long as use spanner is pulled nut and namely can be completed dismounting to tire like this.But such situation still exists following deficiency, a kind of is that the material of bolt is different from the material of wheel hub, easily like this causes relatively rotating of bolt and wheel hub, at this moment, is only difficult to loose nut with a spanner; Another kind of situation is, when infringement appears in bolt, because swollen hole situation appears in the bolt hole on wheel hub, then changes former bolt and cannot realize interference fit, can only be changed by wheel hub simultaneously simultaneously, improve maintenance cost.
Model utility content
The purpose of this utility model is by proposing improvement opportunity scheme to existing bolt, by the technical program, can realize the repeatedly replacing to bolt, and not need to change wheel hub, and bolt there will not be the situation of rotating with hub relative simultaneously.
The utility model is achieved through the following technical solutions:
A kind of Anti-swivel bolt structure, includes wheel hub and bolt; Described wheel hub is provided through the bolt hole of bolt; Described bolt hole inwall is provided with at least one groove along the axis of bolt hole;
The bolt shank that described bolt includes bolt head and is connected with bolt head; The end side surface that described bolt shank is relative with bolt head is provided with screw thread; Described bolt shank is provided with at least one axial projection structure close to one end of bolt head; The quantity of described protruding structure and shape all with described fit depressions.
Described protruding structure radial direction is provided with at least one interrupts grooves.
When described groove is more than two, described groove radial direction divides the circumferential inner wall of bolt hole equally.
The radial cross section of described groove is trapezoidal or U-shaped.
When described protruding structure and described groove fit, very close to each other between the side of described protruding structure and the sidewall of described groove.
The beneficial effects of the utility model are:
By the technical program, when wheel hub coordinates with bolt, the protruding structure on bolt and the groove fit on wheel hub, when needs detaching tyre, only need use spanner nut can be unclamped; When bolt needs to change, because the bolt hole on bolt and wheel hub is not interference fit, namely can changes as long as take off bolt, and need not wheel hub be changed.
Accompanying drawing explanation
Fig. 1 is wheel hub plan view of the present utility model;
Fig. 2 is bolt arrangement schematic diagram of the present utility model.
Embodiment
Describe the technical solution of the utility model in detail by the following examples, following embodiment is only exemplary, only can be used for explaining and the technical solution of the utility model being described, and can not be interpreted as being the restriction to the technical solution of the utility model.
As depicted in figs. 1 and 2, in the technical program, wheel hub 1 structure of automobile does not change, only that man-hour is being added to the bolt hole 11 of wheel hub, on bolt hole inwall, axially at least one groove 111 is processed by boring machine or slotting machine etc., in the present embodiment, the groove of processing is two, and the line of centres of these two grooves is the diameter of bolt hole.In other embodiment of the application, groove can be three, four, five or other groove, the distribution of each groove is, if when groove is three, article three, the circumference radial direction of bolt hole inwall is divided equally by groove is three isometric circular arcs, and similar, the groove of four grooves, five grooves or other quantity is processed according to the mode of three grooves, can ensure that the power put on bolt shank is equal, there will not be the deviator of power like this.
In the present embodiment, the radial cross section of groove 111 is trapezoidal, and in other embodiment of the application, the radial cross section of groove also can be U-shaped or square.
The bolt shank 22 that described bolt 2 includes bolt head 21 and is connected with bolt head; The end side surface that described bolt shank 22 is relative with bolt head 21 is provided with screw thread 221, for same nut screw connection; Described bolt shank 22 is provided with two axial projection structures 222 close to one end of bolt head 21; The quantity of described protruding structure 222 and shape all with described fit depressions.
In use, bolt is aimed at the bolt hole on wheel hub, by the protruding structure on bolt and the groove alignment on wheel hub, bolt is squeezed into bolt hole and namely completes installation.
In this application, protruding structure is provided with a radial interrupts grooves, this structure makes protruding structure disconnect, such advantage is, when protruding structure and groove fit, if there is interference situation to occur, protruding structure there will be distortion, the amount of distortion extends to interrupts grooves direction, reduces the extruding to the recess sidewall on wheel hub, reduces the infringement to wheel hub.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalency thereof.
