Description

Technical Field

[0001] This utility model belongs to the field of bolt technology, and in particular relates to a double-headed wheel hub bolt. Background Technology

[0002] Bolt: A mechanical part, a cylindrical threaded fastener fitted with a nut. It consists of a head and a shank (a cylinder with external threads), and is used to fasten two parts with through holes. This type of connection is called a bolted connection. Since the two parts can be separated by unscrewing the nut, a bolted connection is a detachable connection.

[0003] Existing bolts are prone to tilting during assembly with holes, especially unthreaded holes with a diameter slightly larger than the bolt diameter. This tilting can easily affect the connection strength of the bolt. Therefore, we have specially designed a double-ended hub bolt. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a double-headed hub bolt that achieves high connection strength.

[0005] In view of this, the present invention provides a double-headed wheel hub bolt, comprising:

[0006] A screw with spaced protrusions, a first thread on one side of the screw with spaced protrusions, and a second thread on the screw with spaced protrusions on the other side of the screw;

[0007] A fixing nut is provided, which mates with the first thread, and a locking hole is provided on the fixing nut, with a locking element provided on the locking hole;

[0008] The calibrating nut mates with the second thread and abuts against the mounting surface after being connected to the second thread.

[0009] In the above technical solution, the locking component further includes:

[0010] The adhesive block is placed inside the locking hole;

[0011] The small bolt has a threaded fit with the locking hole, and the rubber block is pressed against the inside of the locking hole.

[0012] Furthermore, the above technical solution also includes:

[0013] A hexagonal protrusion is provided on the end of the screw on one side of the first thread and protrudes beyond the calibrating nut.

[0014] Furthermore, the above technical solution also includes:

[0015] The process groove is located on the mating surface of the locking nut facing the assembly surface and is used to accommodate the spacer protrusion.

[0016] Furthermore, the above technical solution also includes:

[0017] A groove is cut into the wall surface of the locking nut.

[0018] In the above technical solution, the interval protrusions are further designed with various special dimensions such as convex circles, offset long circles, and airfoil convex circles according to different objects;

[0019] The process tank is set accordingly.

[0020] In the above technical solution, furthermore, the diameter of the screw at the first thread is greater than the diameter of the screw at the second thread.

[0021] In the above technical solution, the small bolts are further made of plastic.

[0022] The beneficial effects of this utility model are: the contact area between the nut and the assembly surface is large, and the screw is straightened and corrected during the process of pressing the assembly surface through the threaded engagement with the second thread, thereby improving the connection effect between the first thread and the hole on the assembly surface and thus enhancing the connection strength.

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0028] Example 1:

[0029] This embodiment provides a double-ended wheel hub bolt, including:

[0030] Screw 1, with spaced protrusions 11 on the screw 1, a first thread 12 on one side of the spaced protrusions 11, and a second thread 13 on the other side of the spaced protrusions 11;

[0031] The fixing nut 2 is engaged with the first thread 12, and the fixing nut 2 is provided with a locking hole 21, and a locking element 22 is provided on the locking hole 21;

[0032] The calibrating nut 3 mates with the second thread 13 and abuts against the assembly surface after being connected to the second thread 13.

[0033] As can be seen from this embodiment, a double-headed hub bolt includes a screw 1, a fixing nut 2, and a straightening nut 3;

[0034] The screw 1 is provided with a spacer protrusion 11, which divides the screw 1 into two sections of different lengths. The longer section is formed with a first thread 12 and is set as a connecting end for fitting and fixing the nut 2. The shorter section is formed with a second thread 13 and is set as an adjusting end for fitting and adjusting the nut 3.

[0035] Furthermore, the spacer protrusion 11 can limit the screw 1, thereby preventing the screw 1 from excessively engaging with the hole on the assembly surface and sinking into the hole, which would cause the locking nut to fail to connect properly.

[0036] The large contact area between the calibrating nut 3 and the assembly surface, along with the pressure exerted on the assembly surface by the threaded engagement with the second thread 13, straightens and calibrates the screw 1, thereby improving the connection effect between the first thread 12 and the hole on the assembly surface and enhancing the connection strength.

[0037] Example 2:

[0038] This embodiment provides a double-headed wheel hub bolt, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0039] Locking element 22 includes:

[0040] Adhesive block 221, adhesive block 221 is disposed in locking hole 21;

[0041] The small bolt 222 is threadedly engaged with the locking hole 21, and the rubber block 221 is pressed against the inside of the locking hole 21.

[0042] As can be seen from this embodiment, the locking component 22 includes a rubber block 221 and a small bolt 222;

[0043] The rubber block 221 is set in the locking hole 21 and is pressed against the inside of the locking hole 21 by the small bolt 222 and cooperates with the screw 1 through the locking bolt. After being squeezed by the small bolt 222, the rubber block 221 will have an excessive fit with the first thread 12 on the screw 1, thereby making the connection stable.

[0044] The rubber block 221, together with the small bolt 222, can effectively fill the gap of the locking hole 21, enhance the locking effect, and prevent the locking part 22 from loosening or falling off during use.
