Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to a bolt structure with wide adaptability. Background Technology

[0002] In the existing technology, bolts are commonly used in daily life to assemble objects. When assembling objects, multiple bolts are usually used. However, when using bolts for assembly, objects often have bolt length requirements, so bolts of different lengths are needed to assemble the objects. Since most common bolts are integral structures, when a bolt cannot be used normally, it is often necessary to replace it with the bolt required by the object. If the corresponding bolt is not available at the moment, it will inevitably cause the object to be unable to be assembled normally, which will limit the scope of application of bolts and seriously affect the adaptability of bolts. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies. Most common bolts are integral structures. Since the objects to be assembled usually have bolt length requirements, if the corresponding bolts are not available, the bolts may not be able to properly assemble the objects, which seriously affects the adaptability of the bolts. This utility model provides a bolt structure with wide adaptability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a bolt structure with wide adaptability, comprising: a bolt head, one end of which is provided with a threaded rod, one end of which is provided with a connecting mechanism, the connecting mechanism including a connecting rod at one end of the threaded rod, a top block slidably passing through one side of the bolt head, a first positioning block fixedly connected to one end of the threaded rod, a second positioning block fixedly connected to one side of the bolt head, a bottom block provided inside the threaded rod, a fixing rod fixedly connected to one end of the bottom block, a locking block slidably passing through the inside of the fixing rod, a sliding rod fixedly connected inside the fixing rod, a spring sleeved on the outer surface of the sliding rod, a limit plate fixedly connected to one end of the sliding rod, and a fixing block fixedly connected to one end of the top block.

[0005] In a preferred embodiment, one end of the connecting rod is provided with a first positioning groove that matches the first positioning block, and the other end of the connecting rod is provided with a second positioning groove that matches the second positioning block. One end of the threaded rod is provided with a third positioning groove that matches the bottom block.

[0006] In a preferred embodiment, one end of the threaded rod, one end of the first positioning block, one end of the connecting rod, and one end of the second positioning block are all provided with through holes that are adapted to the fixing rod.

[0007] In a preferred embodiment, the second positioning block has a locking hole on one side that is adapted to the locking block, and one side of the locking block is in contact with one side of the fixing block.

[0008] In a preferred embodiment, one end of the slide rod slides through one side of the locking block, and the other side of the locking block is provided with a sliding groove that matches the limiting plate.

[0009] In a preferred embodiment, one end of the spring is welded to one side of the inner wall of the inner groove of the card block, and the other end of the spring is welded to one side of the limiting plate.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention, through the setting of a connecting mechanism, allows for the selection of connecting rods and fixing rods of appropriate lengths according to requirements. The two ends of the connecting rod are respectively sleeved on the outer surface of the first positioning block of the threaded rod and the outer surface of the second positioning block of the bolt head. The fixing rod is inserted from one end of the threaded rod and pushes the bottom block to move, while the top block is inserted from one side of the bolt head and pushed. The locking block inside the fixing rod self-locks and fixes the second positioning block and the fixing block, ensuring a good and stable connection between the threaded rod, the connecting rod, and the bolt head. This prevents accidental detachment after bolt connection. The bolt length can be adjusted using connecting rods of different lengths, making the bolt suitable for different scenarios, reducing the probability of the bolt failing to properly assemble objects, and improving the adaptability of the bolt.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1-4As shown, this utility model provides a technical solution: a bolt structure with wide adaptability, including: a bolt head 1, one end of which is provided with a threaded rod 2, and one end of the threaded rod 2, one end of the first positioning block 33, one end of the connecting rod 31, and one end of the second positioning block 34 are all provided with through holes adapted to a fixing rod 36. By providing through holes, the fixing rod 36 can slide through the threaded rod 2, the first positioning block 33, the connecting rod 31, and the second positioning block 34, avoiding the fixing rod 36 from being unable to move normally and affecting the overall connection of the bolt. One end of the threaded rod 2 is provided with a connecting mechanism 3, which includes a connecting rod 31 provided at one end of the threaded rod 2, and one end of the connecting rod 31 is provided with a through hole adapted to a fixing rod 36. The first positioning groove is adapted to the first positioning block 33, and the other end of the connecting rod 31 is provided with a second positioning groove adapted to the second positioning block 34. One end of the threaded rod 2 is provided with a third positioning groove adapted to the bottom block 35. By opening the first positioning groove, the second positioning groove, and the third positioning groove, the connecting rod 31, the threaded rod 2, and the bolt head 1 have good positioning measures. The bottom block 35 has good positioning measures inside the threaded rod 2. The top block 32 slides through one side of the bolt head 1. One end of the threaded rod 2 is fixedly connected to the first positioning block 33, and one side of the bolt head 1 is fixedly connected to the second positioning block 34. One side of the second positioning block 34 is provided with a locking hole adapted to the locking block 37. A locking hole is provided, allowing the locking block 37 to be inserted into the interior of the second positioning block 34. This allows the bolt head 1 and the connecting rod 31 to be connected and fixed using the fixing rod 36, the locking block 37, and the second positioning block 34. One side of the locking block 37 contacts one side of the fixing block 311. By setting the locking block 37 to contact the fixing block 311, the locking block 37 can be positioned and limited by the fixing block 311 after fixing the second positioning block 34, preventing the locking block 37 from detaching from the interior of the second positioning block 34. A bottom block 35 is provided inside the threaded rod 2, and a fixing rod 36 is fixedly connected to one end of the bottom block 35. The locking block 37 slides through the interior of the fixing rod 36, and a sliding rod 38 is fixedly connected inside the fixing rod 36. One end of the slide rod 38 slides through one side of the locking block 37, and the other side of the locking block 37 is provided with a groove that matches the limiting plate 310. By providing the groove, the limiting plate 310 can move normally inside the locking block 37. A spring 39 is sleeved on the outer surface of the slide rod 38. One end of the spring 39 is welded to one side of the inner wall of the groove inside the locking block 37, and the other end of the spring 39 is welded to one side of the limiting plate 310. By providing the spring 39, the spring 39 provides sufficient elasticity so that the locking block 37 can maintain a good and stable position inside the fixing rod 36, avoiding affecting the normal movement of the fixing rod 36. One end of the slide rod 38 is fixedly connected to the limiting plate 310, and one end of the top block 32 is fixedly connected to the fixing block 311.

[0022] Working principle:

[0023] like Figure 1-4 As shown, during connection, select the appropriate length of connecting rod 31 and fixing rod 36 according to requirements. After selection, sleeve the connecting rod 31 on the outer surface of the first positioning block 33 at one end of the threaded rod 2, and sleeve the other end of the connecting rod 31 on the outer surface of the second positioning block 34 at one end of the bolt head 1. Keep the threaded rod 2, connecting rod 31, and bolt head 1 in the same position. Insert the fixing rod 36 from the bottom end of the threaded rod 2 and slowly push the bottom block 35 towards the threaded rod 2. The fixing rod 36 gradually slides through the threaded rod 2, the first positioning block 33, the connecting rod 31, and the second positioning block 34 until the bottom block 35 is pushed into the threaded rod 2 and can no longer be pushed. Keep the bottom block 35 in the same position, insert the top block 32 into the bolt head 1, and push the top block 32 to move. The fixing block 311 moves with the top block 32 and contacts the locking block 37 inside the fixing rod 36. One side of the fixing block 311 is set as... After contacting the inclined plane, the locking block 37 moves under the influence of the movement of the fixing block 311, gradually moving out of the inside of the fixing rod 36 and inserting into the locking hole of the second positioning block 34, and sliding on the outer surface of the slide rod 38. The limiting plate 310 moves inside the locking block 37. The spring 39 is affected by the force of the movement of the locking block 37, and its shape gradually changes until it pushes the top block 32 to move until it can no longer be pushed. At this time, the spring 39 is no longer affected by the force, and its shape gradually returns to its original state, and drives the locking block 37 to return to its original position. The locking block 37 gradually moves closer to the other side of the fixing block 311 until the locking block 37 contacts the fixing block 311 and stops moving. The part of the locking block 37 outside the fixing rod 36 inserts into the inside of the second positioning block 34 to fix the second positioning block 34, and the part inside the fixing rod 36 contacts the fixing block 311 and fixes the fixing block 311, completing the self-locking, that is, the bolt is connected as a whole.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
