Technical Field

[0001] The utility model relates to the technical field of double-ended studs, in particular to a high-strength double-ended stud. Background Art

[0002] Double-ended studs are a common type of fastener, generally used to connect two parts that are far apart. Vibration or other forces generated during the use of the parts may cause the nut connected to one end of the double-ended stud to loosen or even fall off, especially for studs with a large pitch and fewer thread turns, which are more prone to falling off. In response to the above situation, we have made technical innovations based on the existing high-strength double-ended studs. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength double-ended stud to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a high-strength double-ended stud, comprising:

[0005] A double-ended stud has guide holes evenly distributed on both the front and rear sides of the threaded portion on its outer side wall. Two sets of first sliding grooves are evenly distributed on the top of the stud, communicating with the guide holes. A second sliding groove is formed on each side opposite to the two sets of first sliding grooves. Two sets of countersunk holes are evenly distributed on the top of the stud, communicating with the second sliding grooves. Wherein:

[0006] An anti-slip component is installed in the first slide groove, and a locking component is installed in the second slide groove.

[0007] Preferably, the anti-slip component includes a first connecting plate, and guide rods are evenly arranged on opposite sides of the two sets of first connecting plates. An anti-slip pad is provided on the side of the guide rod away from the first connecting plate, and a toggle groove is provided on the top of the first connecting plate.

[0008] Preferably, the first connecting plate is located in the first sliding groove, the guide rod and the anti-slip pad are both located in the guide hole, and the top of the first connecting plate is flush with the top of the stud.

[0009] Preferably, the locking assembly includes a second connecting plate, the top of which has a first threaded hole and a second threaded hole, and a cross bolt is screwed into the first threaded hole.

[0010] Preferably, the second connecting plate is disposed on the side of the first connecting plate away from the guide rod, and the second connecting plate is located in the second groove.

[0011] Preferably, the cross bolt is disposed in the countersunk hole, the cross bolt passes through the countersunk hole and is screwed into the first threaded hole, and corresponds to the second threaded hole. The double-ended stud, guide rod, first connecting plate, second connecting plate and cross bolt are all made of carbon steel.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] In this utility model, after the double-ended stud is screwed to the nut, the guide rod moves outward through the outward first connecting plate, thereby causing the anti-slip pad on the outside of the guide rod to press against the inside of the nut, thereby increasing the friction between the double-ended stud and the nut, and thus improving the connection strength between the two.

[0014] When the anti-slip pad rests against the inner side of the nut, the cross bolt will be aligned with the second threaded hole. At this time, use a cross screwdriver to screw the cross bolt into the second threaded hole, thereby fixing the position of the first connecting plate and ensuring that the anti-slip pad can stably contact the nut, thereby ensuring the reliability of the device.

[0015] The stud, guide rod, first connecting plate, second connecting plate, and cross bolt are all made of carbon steel to ensure the strength of the entire stud. Attached Figure Description

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 3A high-strength double-ended stud includes a double-ended stud 1. Guide holes are evenly distributed on both the front and rear sides of the threaded portion on the outer side wall of the double-ended stud 1. Two sets of first sliding grooves are evenly distributed on the top of the double-ended stud 1, communicating with the guide holes. A second sliding groove is distributed on the opposite side of the two sets of first sliding grooves. Two sets of countersunk holes are evenly distributed on the top of the double-ended stud 1, communicating with the second sliding grooves. An anti-slip component is placed in the first sliding groove, and a locking component is placed in the second sliding groove. The anti-slip component includes a first connecting plate 22, with the opposite sides of the two sets of first connecting plates 22 evenly fixed. A guide rod 21 is provided, and an anti-slip pad 2 is fixedly installed on the side of the guide rod 21 away from the first connecting plate 22. A sliding groove 23 is provided on the top of the first connecting plate 22. After the double-ended stud 1 is screwed into the nut, a flathead screwdriver is inserted into the sliding groove 23 and moved outwards, thereby driving the first connecting plate 22 to move outwards synchronously. The first connecting plate 22 then drives the guide rod 21 to move outwards, causing the anti-slip pad 2 on the outer side of the guide rod 21 to press against the inner side of the nut, thus increasing the friction between the double-ended stud 1 and the nut, and thereby improving the connection strength. The first connecting plate 22 is located within the first sliding groove. Both the guide rod 21 and the anti-slip pad 2 are located within the guide hole. The top of the first connecting plate 22 is flush with the top of the double-ended stud 1. The locking assembly includes a second connecting plate 24. The top of the second connecting plate 24 has a first threaded hole 26 and a second threaded hole 27. A cross bolt 25 is screwed into the first threaded hole 26. The second connecting plate 24 is fixedly disposed on the side of the first connecting plate 22 away from the guide rod 21. The second connecting plate 24 is located within the second sliding groove. The cross bolt 25 is rotatably disposed within the countersunk hole. The cross bolt 25 passes through the countersunk hole and is screwed into the first threaded hole 26, and corresponds to the second threaded hole 27. Loosen the Phillips bolt 25 with a Phillips screwdriver and separate it from the first threaded hole 26. Then the first connecting plate 22 can be moved. When the anti-slip pad 2 is pressed against the inside of the nut, the Phillips bolt 25 will be aligned with the second threaded hole 27. Then screw the Phillips bolt 25 into the second threaded hole 27 with a Phillips screwdriver. This completes the fixation of the positions of the second connecting plate 24 and the first connecting plate 22, thereby making the anti-slip pad 2 on the outside of the first connecting plate 22 stably contact the nut. The stud 1, guide rod 21, first connecting plate 22, second connecting plate 24 and Phillips bolt 25 are all made of carbon steel.

[0022] Working principle: When the stud 1 is in use, its top must be exposed. After the stud 1 is screwed to the nut, use a cross screwdriver to loosen the cross bolt 25 and separate it from the first threaded hole 26. Then use a flat-blade screwdriver to insert the toggle slot 23 and move it outward, thereby driving the first connecting plate 22 to move outward synchronously. The first connecting plate 22 drives the guide rod 21 to move outward, thereby driving the anti-slip pad 2 on the outside of the guide rod 21 to press against the inside of the nut, thereby increasing the friction between the stud 1 and the nut, and then To improve the connection strength between the two, when the anti-slip pad 2 is against the inner side of the nut, the cross bolt 25 will be aligned with the second threaded hole 27. At this time, use a cross screwdriver to screw the cross bolt 25 into the second threaded hole 27, thereby completing the position fixation of the second connecting plate 24 and the first connecting plate 22, and then making the anti-slip pad 2 on the outside of the first connecting plate 22 stably contact with the nut. The stud 1, guide rod 21, first connecting plate 22, second connecting plate 24 and cross bolt 25 are all made of carbon steel to ensure the strength of the entire stud 1.
