Description

Technical Field

[0001] This application relates to the field of bolt technology, specifically to an extended bolt that is easy to position. Background Technology

[0002] A bolt is a fastener consisting of a head and a thread. It is used in conjunction with a nut to securely connect two or more parts together through the screw thread. Bolts are widely used in many fields such as machinery manufacturing, construction engineering, and automotive industry. They can reliably withstand various loads such as tension, pressure, and shear force, ensuring the stability and safety of structures or components. Extended bolts, on the other hand, are fasteners that are longer than ordinary bolts. By extending the length of the thread and the shank, they can achieve the connection of parts further away or achieve higher structural stability.

[0003] However, in the existing technology, it has been found that when using extended bolts, they usually need to pass through the mounting holes inside two connectors. Since the bolts are usually not placed horizontally when installed, the operator has to try many times to get the end of the bolt out of the mounting hole on the other side, which makes the installation time-consuming and inefficient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an extended bolt that is easy to position. It has the advantages of positioning the bolt assembly during installation by cooperating with the mounting hole through the top plate, ensuring that the end of the bolt assembly can pass through the mounting hole inside the second connector, thereby improving the bolt installation efficiency, and solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: an extended bolt for easy positioning, comprising a first connecting member, a second connecting member below the first connecting member, mounting holes on the upper surfaces of both the first and second connecting members, a bolt assembly between the first and second connecting members, the bolt assembly comprising a connecting rod, a threaded portion fixedly connected to the bottom end of the connecting rod, equidistantly arranged limiting grooves on the outer surface of the connecting rod, an elastic steel sheet fixedly connected to the inner wall of each limiting groove, a top plate slidably disposed on the inner wall of each limiting groove, the outer surface of each elastic steel sheet abutting against the outer surface of the corresponding top plate, two connecting blocks fixedly connected to the inner wall of each limiting groove, a sliding rod slidably connected to the inner wall of each connecting block, and the end of each sliding rod fixedly connected to the outer surface of the corresponding top plate.

[0006] The above scheme involves setting a bolt assembly between the first and second connectors, with the bolt assembly able to pass through the corresponding mounting hole for installation. A limiting groove is created, and an elastic steel sheet is fixed to its inner wall for installation. The top plate is fitted with the limiting groove, allowing it to slide along the groove. When the operator installs the bolt, they first press the top plate on the outside of the bolt assembly, compressing the elastic steel sheet. Then, the bolt assembly passes through the mounting hole inside the first connector until the top plate is inside the mounting hole. The operator then releases the top plate, and the elastic steel sheet rebounds, causing the outer side of the top plate to fit against the inner wall of the mounting hole inside the first connector, ensuring the coaxiality of the bolt assembly and the mounting hole. The bolt assembly is then pushed further until it exits through the mounting hole inside the second connector. This device facilitates bolt assembly positioning during installation, ensuring the bolt assembly's end can pass through the mounting hole inside the second connector, thereby improving bolt installation efficiency.

[0007] Furthermore, each of the connecting blocks has a groove inside, and a slider is slidably connected to the inner wall of each groove.

[0008] The above scheme involves creating a groove inside the connecting block to position the groove, installing the slider on the inner wall of the corresponding groove, and setting a sliding connection between the groove and the slider, thereby enabling the groove to limit the slider's movement.

[0009] Furthermore, the outer surface of each slider is fixedly connected to the end of the corresponding slide rod away from the top plate.

[0010] By fixing the surface of the slider to the end of the corresponding slide rod away from the top plate through the above scheme, the slide rod and slider can move together. This device can limit the displacement distance of the slide rod through the connection between the slide groove and the slider, and at the same time achieve the effect of preventing the slide rod and the top plate from falling off.

[0011] Furthermore, a nut is provided below the second connector, and the inner wall of the nut is threadedly connected to the outer surface of the threaded portion.

[0012] With the above solution, a nut is provided below the second connector and the nut is connected to the threaded part, so that when the nut is connected to the threaded part, the first connector, the second connector and the intermediate component can be fixed.

[0013] Furthermore, the outer surface of the bolt assembly is fitted with two pressure plates and two conical gaskets.

[0014] The above scheme involves placing pressure plates and conical washers on the surface of the bolt assembly. Two pressure plates and two conical washers are arranged, with one set of pressure plates and conical washers located between the first connector and the bolt assembly, and the other set of pressure plates and conical washers located between the second connector and the nut.

[0015] Furthermore, the side of each of the pressure plates that is close to each other is adapted to the side of the corresponding conical gasket that is far from each other.

[0016] The above method involves bonding the pressure plate with the corresponding conical gasket. The surface of the conical gasket has an inclined surface, and the inner wall of the pressure plate has an inclined surface that fits into the conical gasket. When the bolt assembly is connected to the nut, the pressure plate and the conical gasket fit tightly together to form a conical surface.

[0017] Furthermore, each of the conical gaskets has an annular groove on the side that is close to each other, and a sealing ring is fixedly installed on the inner wall of each annular groove.

[0018] The above method involves creating an annular groove on the side of the conical gaskets that are close to each other, thereby positioning the annular groove. The sealing ring is then installed on the inner wall of the corresponding annular groove, thus achieving the installation of the sealing ring. When the bolt assembly is connected to the nut, the sealing ring is deformed under pressure inside the annular groove.

[0019] Furthermore, the side of each conical gasket and sealing ring that is close to each other is in contact with the side of the corresponding first connector and second connector that is far from each other.

[0020] The above scheme involves fitting the conical gasket and the sealing ring close to each other onto the corresponding first and second connectors. This allows the sealing ring to deform and fit against the first and second connectors after the bolt assembly and nut are connected. The conical gasket is squeezed by the pressure plate and fits against the first and second connectors, ensuring that the connection part of the bolt assembly has sufficient friction after installation.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This extended bolt, designed for easy positioning, incorporates components such as an elastic steel sheet and a top plate. During installation, the top plate is first pressed to compress the elastic steel sheet, allowing the bolt assembly to pass through the mounting hole inside the first connector until the top plate is positioned within the mounting hole. The top plate is then released, and the elastic steel sheet allows the outer side of the top plate to align with the inner wall of the mounting hole in the first connector, ensuring coaxiality between the bolt assembly and the mounting hole. The bolt assembly is then pushed further until it emerges from the mounting hole in the second connector, thus achieving proper positioning during installation and ensuring the end of the bolt assembly can pass through the mounting hole in the second connector, thereby improving installation efficiency. Before installation, a set of pressure plates and tapered washers are placed on the surface of the bolt assembly. After installation, another set of pressure plates and tapered washers are placed on the surface of the bolt assembly. The nut is then connected to the threaded portion. After installation, the two sets of pressure plates and tapered washers work together to ensure sufficient friction at the connection point of the bolt assembly. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 2 and Figure 4 This embodiment provides an extended bolt for easy positioning, comprising a first connecting member 1, a second connecting member 2 below the first connecting member 1, mounting holes 3 on the upper surfaces of both the first connecting member 1 and the second connecting member 2, and a bolt assembly 4 between the first connecting member 1 and the second connecting member 2. The bolt assembly 4 includes a connecting rod 401, a threaded portion 402 fixedly connected to the bottom end of the connecting rod 401, and equidistantly arranged limiting grooves 5 on the outer surface of the connecting rod 401. An elastic steel sheet 6 is fixedly connected to the inner wall of each limiting groove 5, and a top plate 7 is slidably disposed on the inner wall of each limiting groove 5. The outer surface of each elastic steel sheet 6 abuts against the outer surface of the corresponding top plate 7. Two connecting blocks 8 are fixedly connected to the inner wall of each limiting groove 5, and a sliding rod 11 is slidably connected to the inner wall of each connecting block 8. The end of each sliding rod 11 is fixedly connected to the outer surface of the corresponding top plate 7. The bolt assembly 4 is positioned between the first connecting member 1 and the second connecting member 2, and the bolt assembly 4 can penetrate the first connecting member 1 and the second connecting member 2. The corresponding mounting hole 3 is provided to install the bolt assembly 4. A limiting groove 5 is provided and the elastic steel sheet 6 is fixed to its inner side wall to install the elastic steel sheet 6. The top plate 7 is fitted with the limiting groove 5 so that the top plate 7 can slide along the limiting groove 5. When the operator installs the bolt, first press the top plate 7 on the outside of the bolt assembly 4. At this time, the elastic steel sheet 6 is compressed. Then, the bolt assembly 4 is passed through the mounting hole 3 inside the first connector 1 until the top plate 7 is located in the mounting hole 3 inside the first connector 1. At this time, the operator will then place the top plate 7... Release the spring, and the elastic steel sheet 6 will cause the outer side of the top plate 7 to fit against the inner wall of the mounting hole 3 inside the first connector 1, ensuring the coaxiality of the bolt assembly 4 and the mounting hole 3 inside the first connector 1. Then continue to push the bolt assembly 4 until it passes through the mounting hole 3 inside the second connector 2. This device facilitates the positioning of the bolt assembly 4 during installation, ensuring that the end of the bolt assembly 4 can pass through the mounting hole 3 inside the second connector 2, thereby improving the bolt installation efficiency.

[0026] Please see Figure 4 and Figure 5Each connecting block 8 has a groove 9 inside, and a slider 10 is slidably connected to the inner wall of each groove 9. The groove 9 is located inside the connecting block 8 to position it. The slider 10 is installed on the inner wall of the corresponding groove 9, and the groove 9 and the slider 10 are slidably connected, so that the groove 9 can limit the slider 10. The outer surface of each slider 10 is fixedly connected to the end of the corresponding slide rod 11 away from the top plate 7. The surface of the slider 10 is fixed to the end of the corresponding slide rod 11 away from the top plate 7, so that the slide rod 11 and the slider 10 can move together. This device can limit the displacement distance of the slide rod 11 through the connection between the groove 9 and the slider 10, and at the same time, prevent the slide rod 11 and the top plate 7 from falling off.

[0027] Please see Figure 1 , Figure 2 and Figure 3 A nut 12 is provided below the second connector 2. The inner wall of the nut 12 is threadedly connected to the outer surface of the threaded part 402. The nut 12 is provided below the second connector 2 and connected to the threaded part 402, so that when the nut 12 is connected to the threaded part 402, the first connector 1, the second connector 2 and the intermediate component can be fixed.

[0028] Please see Figure 2 and Figure 6Two pressure plates 13 and two conical washers 14 are fitted onto the outer surface of the bolt assembly 4. The pressure plates 13 and conical washers 14 are fitted onto the surface of the bolt assembly 4. Two pressure plates 13 and two conical washers 14 are arranged respectively. One set of pressure plates 13 and conical washers 14 is located between the first connector 1 and the bolt assembly 4, and the other set of pressure plates 13 and conical washers 14 is located between the second connector 2 and the nut 12. Each pressure plate 13 is close to one another. Each conical gasket 14 has a beveled surface on its corresponding side, and the inner wall of the pressure plate 13 has a beveled surface that fits into the conical gasket 14. When the bolt assembly 4 is connected to the nut 12, the pressure plate 13 and the conical gasket 14 are tightly fitted together to form a conical surface. Each conical gasket 14 has an annular groove 15 on its adjacent side, and the inner wall of each annular groove 15 has a beveled surface that fits into the conical gasket 14. A sealing ring 16 is fixedly installed. An annular groove 15 is formed on the side of the conical gasket 14 that is close to each other, thereby positioning the annular groove 15. The sealing ring 16 is installed on the inner wall of the corresponding annular groove 15, thereby installing the sealing ring 16. When the bolt assembly 4 is connected to the nut 12, the sealing ring 16 is deformed under pressure inside the annular groove 15. The side of each conical gasket 14 and the sealing ring 16 that is close to each other is in contact with the side of the corresponding first connector 1 and second connector 2 that is far from each other. The side of the conical gasket 14 and the sealing ring 16 that is close to each other is in contact with the corresponding first connector 1 and second connector 2. Thus, after the bolt assembly 4 and the nut 12 are connected, the sealing ring 16 deforms and is in contact with the first connector 1 and the second connector 2. The conical gasket 14 is squeezed by the pressure plate 13 and is in contact with the first connector 1 and the second connector 2, ensuring that the connection part of the bolt assembly 4 has sufficient friction after installation.

[0029] The working principle of the above embodiment is as follows: In use, firstly, a set of pressure plates 13 and conical gaskets 14 are placed on the surface of the bolt assembly 4, and then the top plate 7 on the outside of the bolt assembly 4 is pressed. At this time, the elastic steel sheet 6 is compressed. Subsequently, the bolt assembly 4 is pushed through the mounting hole 3 inside the first connector 1 until the top plate 7 is located inside the mounting hole 3 inside the first connector 1. At this time, the operator releases the top plate 7. Through the rebound of the elastic steel sheet 6, the outer side of the top plate 7 is made to fit against the inner wall of the mounting hole 3 inside the first connector 1, thereby ensuring the coaxiality of the bolt assembly 4 and the mounting hole 3 inside the first connector 1. Then, the operator continues to push the bolt assembly 4 until the bolt assembly 4 passes through the mounting hole 3 inside the second connector 2. When installing the bolt assembly 4, this device facilitates the positioning of the bolt assembly 4, ensuring that the end of the bolt assembly 4 can pass through the mounting hole 3 inside the second connector 2, thereby improving the bolt installation efficiency. At this time, another set of pressure plates 13 and conical washers 14 are placed on the surface of the bolt assembly 4, and then the nut 12 is connected to the threaded part 402. Through the continuous feeding of the nut 12, the sealing ring 16 is deformed under pressure. At this time, the pressure plates 13 and conical washers 14 are tightly fitted until the installation of the bolt assembly 4 and the nut 12 is completed. At this time, the sealing ring 16 and the conical washers 14 are tightly fitted with the first connector 1 and the second connector 2, ensuring that the connection part of the bolt assembly 4 has sufficient friction after installation.
