Description

Technical Field

[0001] The utility model relates to the technical field of adjusting bolts, in particular to an adjusting bolt with a limiting structure. Background Art

[0002] The conventional bolts are usually composed of a screw and a nut, and the screw and the bolt are usually used to clamp and fix the base material. The screw is provided with a thread, and a thread groove is provided in the middle of the nut to match it. When the screw is rotated clockwise for several turns so that the base material reaches the end of the thread groove, the screw and the nut can fix the base material together. With the development of the times, a base material with a special threaded hole has appeared on the market. This threaded hole has a tooth-like inner wall on the periphery of a ratchet. The inner wall of this threaded hole can be fixed with the screw more stably. The position of the threaded hole is determined during the manufacture of this base material, which can save the subsequent drilling process. However, this base material with a threaded hole is inconvenient to fix with a traditional bolt, and the traditional screw without a nut is fixed by clockwise rotation and clamping. After long-term use, it is easy to be affected by vibration, causing the screw and the threaded hole of the base material to loosen, and the transmission bolt is not easy to adjust. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an adjusting bolt with a limiting structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a nut and a screw, the screw has a thread groove, the thread groove has a first limit groove, the first limit groove has a second limit groove between the nut, an adjustment groove for adjusting the position of the bolt is formed between the first limit groove and the second limit groove, the starting end of the second limit groove is connected to the adjustment groove, and the end can be connected to the nut, one end of the first limit groove is connected to the adjustment groove, and the other end is connected to the thread groove toward the starting end of the screw, the first limit groove is provided with a first limit piece for cooperating with the substrate connected thereto to limit the position, and the second limit groove is provided with a second limit piece for cooperating with the positioning of the substrate connected thereto.

[0005] The above technical solution can produce the following effects: a thread groove is provided on the screw for screwing the screw into a substrate with a threaded hole, a first limiting groove and a second limiting groove are provided in the thread groove, wherein the first limiting groove is closest to the starting end of the screw, and the second limiting groove is closest to the end of the screw, that is, the direction of the nut, and an adjustment groove is provided between the first limiting groove and the second limiting groove for adjusting the position of the screw, or for adjusting the position of the substrate on the screw. The provision of two limiting grooves can make the connection between the screw and the substrate more stable. After the first limiting groove of the screw passes through the threaded hole of the substrate, the position of the threaded hole of the substrate is at the position of the adjustment groove, which is convenient for adjustment. The screw is not easy to fall out of the threaded hole of the substrate during adjustment, and the connection is more stable.

[0006] As a further improvement of the present invention, the first limiting member is a breakable thin sheet, which is evenly distributed along the inner wall of the first limiting groove. One end of the breakable thin sheet is connected to the inner wall of the first limiting groove, and the other end extends counterclockwise. The end of the breakable thin sheet extending in the counterclockwise direction can be offset against the substrate used to connect with it.

[0007] The effect that can be produced by adopting the above technical scheme is: a breakable thin piece is set in the second limiting member, one end of the breakable thin piece is connected to the inner wall of the first limiting groove and the other end extends counterclockwise. After the screw rotates clockwise into the threaded hole of the substrate and passes through the first limiting groove, the breakable thin piece set in the first limiting groove can be offset against the inner wall of the threaded hole. Under non-human action, the screw is not easy to fall out of the first limiting groove, and the limiting effect is good. If the screw is rotated counterclockwise under human action to break the breakable thin piece, the screw can be rotated counterclockwise to fall out of the threaded hole of the substrate, which can both limit the position and facilitate adjustment, and is easy to operate.

[0008] As a further improvement of the present invention, the second limiting member is a limiting sheet, one end of the limiting sheet is connected to the inner wall of the second limiting groove, and the other end extends counterclockwise. The end of the limiting sheet extending counterclockwise can be offset against the base material used to connect it.

[0009] The effect that can be produced by adopting the above technical scheme is: a limiting sheet is set as the second limiting piece. Unlike the breakable sheet, the limiting sheet cannot be broken by rotating the screw counterclockwise. In this scheme, the limiting sheet can be made of metals that are not easy to break, such as steel sheets and iron sheets. When the screw is rotated into the second limiting groove, the screw cannot rotate counterclockwise. At this time, the screw is not easy to loosen after being tightened with the threaded hole of the substrate, thereby improving the connection strength, and the connection is stable and the structure is simple.

[0010] As a further improvement of the present invention, the limiting sheet and the inner wall of the second limiting groove are integrally formed.

[0011] The above technical solution can produce the following effects: by integrally forming the limiting sheet with the inner wall of the second limiting groove, the strength of the limiting sheet can be improved, the limiting sheet is not easily broken, and the manufacturing is more convenient.

[0012] As a further improvement of the present invention, a breakable notch is provided on the side wall of the breakable sheet facing the inner wall of the first limiting groove.

[0013] The effect produced by adopting the above technical solution is: by setting an easy-to-break notch on the side of the inner wall of the breakable sheet facing the first limit groove, it is not easy to break the breakable sheet when the screw rotates clockwise to extrude the breakable sheet. When the screw enters the adjustment groove and then rotates counterclockwise to disengage from the first limit groove toward the starting end of the screw, it is more convenient. The breakable sheet is easier to break by human intervention, and the structure is simple and easy to operate.

[0014] As a further improvement of the present invention, the nut and the screw are integrally formed, and the end of the second limiting groove can abut against the side wall of the nut facing the second limiting groove.

[0015] The above technical solution can produce the following effects: the nut and the screw are integrally formed, which makes manufacturing more convenient; the end of the second limiting groove is abutted against the nut to prevent the screw from rotating excessively and falling out of the threaded hole of the substrate; and the structure is simple.

[0020] The present invention provides an embodiment of an adjusting bolt with a limiting structure as shown in the figure. To achieve the above-mentioned purpose, the present invention provides an adjusting bolt with a limiting structure. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: comprising a nut 2 and a screw rod 1, the screw rod 1 having a thread groove 3, the thread groove 3 having a first limiting groove 4, a second limiting groove 5 between the first limiting groove 4 and the nut 2, an adjusting groove 6 for adjusting the position of the bolt is formed between the first limiting groove 4 and the second limiting groove 5, the starting end of the second limiting groove 5 is connected to the adjusting groove 6, and the end can be connected to the nut 2, one end of the first limiting groove 4 is connected to the adjusting groove 6, and the end of the second limiting groove 5 is connected to the adjusting groove 6. The adjusting groove 6 is connected, and the other end is connected to the thread groove 3 toward the starting end of the screw 1. The first limiting groove 4 is provided with a first limiting piece for cooperating with the substrate connected thereto, and the second limiting groove 5 is provided with a second limiting piece for cooperating with the substrate connected thereto. The thread groove 3 is provided on the screw 1 for screwing the screw 1 into the substrate with the threaded hole 10, and the first limiting groove 4 and the second limiting groove 5 are provided in the thread groove 3, wherein the first limiting groove 4 is closest to the starting end of the screw 1, and the second limiting groove 5 is closest to the end of the screw 1, that is, the direction of the nut 2. An adjusting groove 6 is provided between the first limiting groove 4 and the second limiting groove 5 for adjusting the screw The position of the rod 1, or it is used to adjust the position of the substrate on the screw 1. The two limit grooves are set to make the connection between the screw 1 and the substrate more stable. After the first limit groove 4 of the screw 1 passes through the threaded hole 10 of the substrate, the position of the threaded hole 10 of the substrate is at the position of the adjustment groove 6, which is convenient for adjustment. The adjustment is convenient, and the screw 1 is not easy to come out of the threaded hole 10 of the substrate during adjustment, and the connection is more stable. The first limit member is a breakable thin piece 7, and the breakable thin piece 7 is evenly distributed along the inner wall of the first limit groove 4. One end of the breakable thin piece 7 is connected to the inner wall of the first limit groove 4, and the other end extends in the counterclockwise direction. The breakable thin piece 7 is facing counterclockwise. One end of the extension can be offset against the base material connected thereto, and a breakable thin piece 7 is provided in the second limiting member, one end of the breakable thin piece 7 is connected to the inner wall of the first limiting groove 4, and the other end extends counterclockwise. After the screw 1 rotates clockwise into the threaded hole 10 of the base material and passes through the first limiting groove 4, the breakable thin piece 7 provided in the first limiting groove 4 can be offset against the inner wall of the threaded hole 10. Under non-human action, the screw 1 is not easy to come out of the first limiting groove 4, and the limiting effect is good. If the screw 1 is rotated counterclockwise under human action to break the breakable thin piece 7, the screw 1 can be rotated counterclockwise to come out of the threaded hole 10 of the base material, which can both limit the position and facilitate adjustment.The second limiting member is a limiting sheet 8, one end of which is connected to the inner wall of the second limiting groove 5, and the other end extends counterclockwise. The end of the limiting sheet 8 extending counterclockwise can be against the base material connected thereto. A limiting sheet 8 is provided as the second limiting member. Unlike the breakable sheet 7, the limiting sheet 8 cannot be broken by rotating the screw 1 counterclockwise. In this scheme, the limiting sheet 8 can be made of a metal that is not easy to break, such as a steel sheet or an iron sheet. When the screw 1 is rotated into the second limiting groove 5, the screw 1 cannot be rotated counterclockwise. At this time, it is not easy to loosen after tightening the screw 1 and the threaded hole 10 of the base material, thereby improving the connection strength, and the connection is stable and the structure is simple. The limiting sheet 8 is integrally formed with the inner wall of the second limiting groove 5. The limiting sheet 8 is integrally formed with the inner wall of the second limiting groove 5 to improve the strength of the limiting sheet 8, is not easy to break, and is more convenient to manufacture; the side wall of the breakable sheet 7 facing the inner wall of the first limiting groove 4 is provided with an easy-to-break notch 9. The easy-to-break notch 9 is provided on the side of the breakable sheet 7 facing the inner wall of the first limiting groove 4 to make it difficult for the screw 1 to break when the breakable sheet 7 is squeezed clockwise. When the screw 1 enters the adjusting groove 6 and then rotates counterclockwise to disengage from the first limiting groove 4 toward the starting end of the screw 1, it is more convenient. The breakable sheet 7 is more easily broken by human intervention, has a simple structure, and is easy to operate;The nut 2 is integrally formed with the screw rod 1, and the end of the second limiting groove 5 can be abutted against the side wall of the nut 2 facing the second limiting groove 5. The nut 2 and the screw rod 1 are integrally formed, which is more convenient to manufacture. The end of the second limiting groove 5 is abutted against the nut 2 to prevent the screw 1 from rotating too much and falling out of the threaded hole 10 of the substrate. The structure is simple. When implementing this scheme, those skilled in the art first insert the starting end of the screw 1 into the special threaded hole 10 of the substrate. The screw 1 of this scheme can be used to be inserted into this special threaded hole 10. When the first limiting groove 4 on the screw 1 enters the threaded hole 10, the breakable thin piece 7 of the first limiting member can contact the threaded hole 10 of the substrate. When the first limiting groove 4 passes through the threaded hole 10 of the substrate, the threaded hole 10 of the substrate is in the adjustment groove 6. At this time, those skilled in the art can adjust the position of the screw 1 and the substrate by rotating the screw 1 or rotating the substrate. This adjustment in this scheme is fine-tuning, which belongs to a small adjustment position. The adjustment range can be adjusted according to the conditions in the art. The length of the adjustment slot 6 set by the technician is determined. If the adjustment range of the adjustment slot 6 cannot meet the requirements, those skilled in the art can manually rotate the screw 1 counterclockwise so that the breakable thin piece 7 on the screw 1 contacts and squeezes the threaded hole 10 of the substrate and breaks it. The breakable thin piece 7 in this solution is a one-time break. After breaking, the screw 1 can no longer be limited by the first limiting member. If the adjustment range of the adjustment slot 6 meets the requirements, there is no need to reversely rotate the screw 1 to destroy the breakable thin piece 7. At this time, the breakable thin piece 7 can limit the screw 1 to prevent the screw 1 from falling out of the threaded hole 10 of the substrate. After the skilled person in the art determines the position of the screw 1 or the substrate, he or she continues to rotate the screw 1 so that the second limiting slot 5 of the screw 1 enters the threaded hole 10 of the substrate and the second limiting member, i.e., the limiting thin piece 8, abuts against the inner wall of the threaded hole 10 of the substrate to prevent the screw 1 from falling out of the substrate, making the connection between the screw 1 and the substrate more stable, the connection strength higher, and convenient to adjust.
