Technical Field

[0001] The utility model provides a bolt assembly with a self-locking function, belonging to the technical field related to bolt installation. Background Art

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that fits a nut. It consists of a head and a shank (a cylindrical body with external threads). It is used to fasten two parts with through-holes together with a nut. This type of connection is called a bolt connection. Removing the nut from the bolt allows the two parts to separate, making a bolt connection a detachable connection.

[0003] Based on the above, the inventors found that:

[0004] There are many self-locking methods for bolts in the prior art, among which self-locking nuts and spring washers are more common. However, there is still a risk of falling off. There is no limit component used with the bolts, which can easily cause accidents when falling off, which is unsafe.

[0005] Therefore, in view of this, the existing structure is studied and improved, and a bolt assembly with a self-locking function is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the traditional bolt assembly with a self-locking function lacks a limiting assembly, and an accident is easily caused when the self-locking nut falls off, which is unsafe.

[0007] In order to solve the above problems, the utility model proposes a technical solution: a bolt assembly with a self-locking function, including a bolt auxiliary tool, a bolt, a self-locking nut, and a workpiece, the bolt auxiliary tool is used to limit the bolt, a limiting assembly is provided on the outside of the bolt and the limiting assembly is placed inside the workpiece, the limiting assembly includes a fixed plate 1, a fixed plate 2, two movable plates, a fixed ring, and a spring assembly, the fixed plate 1 and the fixed plate 2 are arranged opposite to each other and are both placed above the fixed ring.

[0008] Furthermore, the inner side of the workpiece is provided with groove one and groove two is provided between the two groove ones. The groove one and groove two are connected to each other through a connecting groove and a through hole is provided at the bottom of the groove two.

[0009] Furthermore, the fixing ring is placed on the outside of the bolt and fixedly connected to it, and the fixing ring is placed at the bottom of groove two, fixing plate one and fixing plate two are placed on both sides of the bolt column, and a limiting groove is provided on the inner side of fixing plate two, and a limiting block adapted to the limiting groove is provided on fixing plate one, and the limiting block is placed in the limiting groove.

[0010] Furthermore, the two movable plates are respectively placed on the outside of the fixed plate 1 and the fixed plate 2 and fixedly connected thereto, and the movable plates are placed in the groove 1 and the communicating groove.

[0011] Furthermore, the spring assembly is fixedly connected between the movable plate and the inner wall of the communicating groove.

[0012] Furthermore, the bolt extends to below the workpiece and a self-locking nut is connected to the end of the bolt and located at the bottom of the workpiece.

[0013] Due to the adoption of the above technical solution, the beneficial effects of the bolt assembly with self-locking function of the utility model are as follows:

[0014] The utility model sets a limit assembly and uses the fixing plates 1 and 2 to limit the bolt. When the self-locking nut at the end of the bolt falls off, the bolt is blocked by the fixing plates 1 and 2, so that it will not fall off from the main workpiece so quickly, which is safer.

[0022] 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.

[0023] This application fully explains the problems of the prior art in the technical background, and there are no general or abstract problems. The problems to be solved by this application are described in detail in the following utility model content and specific implementation methods, and the technical problems to be solved by the technical solution are clarified, and it is determined that the technical solution of this application has beneficial effects relative to the objective prior art.

[0024] See also Figure 1-4 As shown: The utility model provides a bolt assembly with a self-locking function: it includes a bolt auxiliary tool 1, a bolt 2, a self-locking nut, and a workpiece 3. The bolt auxiliary tool 1 is used to limit the bolt 2. The bolt 2 extends to the bottom of the workpiece 3 and the end of the bolt 2 is located at the bottom of the workpiece 3 and is connected with a self-locking nut. A limiting assembly is provided on the outside of the bolt 2 and the limiting assembly is placed inside the workpiece 3. The limiting assembly includes a fixed plate 1 4, a fixed plate 2 5, two movable plates 6, a fixed ring 7, and a spring assembly 13. The fixed plate 1 4 and the fixed plate 2 5 are arranged relatively to each other and are both placed above the fixed ring 7.

[0025] like Figure 2-4 As shown, groove 1 8 is provided on the inner side of the workpiece 3 and groove 2 9 is provided between the two grooves 1 8 . The groove 1 8 and groove 2 9 are connected to each other through a connecting groove 10 and a through hole 11 is provided at the bottom of the groove 2 9 .

[0026] The fixing ring 7 is placed on the outside of the bolt 2 and fixedly connected to it, and the fixing ring 7 is placed at the bottom of the groove 2 9. The fixing plate 1 4 and the fixing plate 2 5 are placed on both sides of the bolt 2 column, and a limiting groove 12 is provided on the inner side of the fixing plate 2 5. A limiting block adapted to the limiting groove 12 is provided on the fixing plate 1 4, and the limiting block is placed in the limiting groove 12.

[0027] The two movable plates 6 are respectively placed outside the fixed plate 1 4 and the fixed plate 2 5 and fixedly connected thereto, and the movable plates 6 are placed in the groove 1 8 and the connecting groove 10 .

[0028] The spring assembly 13 is fixedly connected between the moving plate 6 and the inner wall of the communicating groove 10 .

[0029] The principle of the bolt assembly with a self-locking function of the utility model is: the bolt auxiliary tool has no special structure, and a groove adapted to the upper head of the bolt is provided on the inner side. The upper end of the bolt is placed in the groove, and the bolt is prevented from rotating when installed in conjunction with the self-locking nut. Otherwise, it is difficult to install the self-locking nut, and a wrench can be used instead. The self-locking nut adopts the existing technology. The above can all be achieved by the existing technology, without doubt.

[0030] like Figure 3 As shown, pinch the exposed position of the movable plate with your hand to squeeze the spring assembly backward (the spring assembly is a combination of a spring and a telescopic rod, and the spring is placed on the outside of the telescopic rod, and existing technology can be used). The movable plate moves in the connecting groove and groove one, and then use the existing tool to insert it between groove one and the movable plate so that the movable plate does not reset. The bolt auxiliary tool is clamped on the bolt, and then the self-locking nut is screwed on the end of the bolt, and the bolt is placed in groove two and the through hole. The fixing ring is at the bottom of groove two. When the tool is removed at this time, the movable plate is reset under the action of the spring assembly, and the two movable plates respectively drive the fixed plate one and the fixed plate two to be clamped between the fixing ring and the top of the bolt, and the limit block is placed in the limit groove.

[0031] The utility model provides a limiting component so that when the self-locking nut falls off, the bolt is blocked by the first fixing plate and the second fixing plate, so that the bolt and the main workpiece will not fall off so quickly, which is safer.

[0032] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
