Description

Technical Field

[0001] This utility model belongs to the field of automotive bolt technology, and in particular relates to an automotive bolt structure with visible tightening progress. Background Technology

[0002] Automotive bolts are fasteners specifically designed for automobile manufacturing and repair. Their main function is to secure various automotive components (such as the engine, chassis, body, and electrical system) together via threaded connections, ensuring the stability and safety of the vehicle structure.

[0003] For example, Chinese patent CN219549306U discloses a bolt structure for automobiles with visible tightening progress, relating to the field of bolt technology. It includes a threaded shell with a bolt on the outer side of one end. A base plate is welded to the inner side of the threaded shell at the end away from the bolt. A spring is welded to the side of the base plate inside the threaded shell, and a movable plate is welded to the end of the spring away from the base plate. The length of the spring is less than the length of the threaded shell. In use, one end of the bolt can move against the movable plate. An indicator ring, fixedly connected to the movable plate via two connecting blocks, also moves synchronously with the movable plate. The indicator ring is located on the outer side of the threaded shell, so when the bolt moves against the movable plate, the indicator ring can track the specific position of the bolt's end inside the threaded shell in real time. By observing the position of the indicator ring on the outer side of the threaded shell, the operator can determine the length of the bolt driven into the threaded shell. The operation is simple and the observation is clearer.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, if the spring is under constant compression during use, it will not be able to return to its original length, resulting in a shortened free height, a significant decrease in elasticity, and ultimately, loss of function. Furthermore, the device requires a tool for rotation; if the operating space is limited, the tool may not be able to reach the bolt head or properly insert it, directly hindering installation, disassembly, and adjustment operations. Therefore, we propose a visible tightening progress structure for automotive bolts. Utility Model Content

[0006] The purpose of this invention is to provide a bolt structure for automobiles with visible tightening progress, in order to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a bolt structure for automobiles with visible tightening progress, including a threaded post and a threaded sleeve, and further comprising:

[0008] A cross handle is fixedly installed on the top of a threaded post. A hexagonal block is inserted into the cross handle. A threaded sleeve is threaded onto the threaded post. A rotating post is rotatably installed at the bottom of the threaded post. A fixed plate is fixedly installed at the bottom of the rotating post. The fixed plate is inserted into the threaded sleeve.

[0009] A sliding groove is formed inside a fixed plate. A sliding column is slidably installed inside the sliding groove. A spring that is fixed to the inner wall of the sliding groove is fixedly installed at one end of the sliding column. A guide groove is formed on the threaded sleeve. The other end of the sliding column passes through the sliding groove and extends into the guide groove. The other end of the sliding column is slidably connected to the guide groove.

[0010] A plurality of fixing components, all of which are located within the hexagonal block and are used to fix the position of the hexagonal block.

[0011] In this technical solution, when it is necessary to disassemble the entire device, a tool is used to rotate the hexagonal block and drive the threaded column to rotate through the cross handle. Under the action of the thread, the threaded column drives the fixed plate to move upward, while the sliding column slides in the guide groove. During the movement of the sliding column, the operator can check the tightening progress of the entire device. When the sliding column slides to the appropriate position, the guide groove will squeeze the other end of the sliding column. The other end of the sliding column is squeezed and slides towards the spring. At the same time, the spring is squeezed and contracts. When the sliding column is completely inserted into the sliding groove, the threaded sleeve can be removed.

[0012] With the fixed components in place, the hexagonal block and the cross handle are tightly connected. When the disassembly space is small and it is inconvenient to use tools, pull the hexagonal block upwards. With the fixed components in place, the hexagonal block can be completely removed. At this time, the operator can turn the cross handle. The shape of the cross handle makes it easy for the operator to turn manually. Even in small spaces, manual disassembly can be performed, and the operation is convenient and simple.

[0013] In the above technical solution, the fixing component further includes:

[0014] The groove is formed inside the hexagonal block, and a metal spring is fixedly installed inside the groove. A limit groove is formed on the cross handle. One side of the metal spring passes through the groove and extends into the limit groove, and the metal spring is inserted into the limit groove.

[0015] In this technical solution, under the elastic force of several metal springs, the metal springs are respectively locked in several limiting grooves, making the hexagonal block and the cross handle tightly connected. When the disassembly space is small and it is inconvenient to use tools, the hexagonal block is pulled upward, and the hexagonal block drives the metal springs to move upward. At the same time, the limiting grooves squeeze the metal springs respectively, and the metal springs enter the grooves respectively. When the hexagonal block is completely removed, the operator can rotate the cross handle. The shape of the cross handle makes it easy for the operator to rotate manually. Even in small spaces, manual disassembly can be used, and the operation is convenient and simple.

[0016] In the above technical solution, further, a plurality of the metal spring pieces are distributed in a ring at equal intervals on the hexagonal block.

[0017] In this technical solution, under the action of the elastic force of several metal springs, several metal springs are respectively stuck in several limiting grooves, so that the hexagonal block and the cross handle are tightly connected.

[0018] In the above technical solution, furthermore, the other end of the sliding column is arc-shaped.

[0019] In this technical solution, the guide groove will squeeze the other end of the sliding column, and the other end of the sliding column will slide in the direction of the spring under the pressure.

[0020] Furthermore, in the above technical solution, the rotating column and the fixed disk are integrally formed.

[0021] In this technical solution, the stability of the rotating column and the fixed disk is ensured during use.

[0022] In the above technical solution, the cross-section of the rotating column is T-shaped.

[0023] In this technical solution, it is ensured that the rotating column can rotate stably within the threaded column.

[0024] In the above technical solution, the hexagonal block is in close contact with the cross handle.

[0025] In this technical solution, the worker uses a tool to rotate the hexagonal block and drives the threaded column to rotate through the cross handle.

[0026] The beneficial effects of this utility model are:

[0027] 1. The tightening progress of this automotive bolt structure is visible. When the entire device needs to be disassembled, a tool is used to rotate the hexagonal block and drive the threaded column to rotate through the cross handle. Under the action of the thread, the threaded column drives the fixed plate to move upward, while the sliding column slides in the guide groove. During the movement of the sliding column, the operator can see the tightening progress of the entire device, and the entire device can be used for a long time.

[0028] 2. This automotive bolt structure with visible tightening progress features a fixed assembly that tightly connects the hexagonal block and the cross handle. When the disassembly space is limited and tools are inconvenient to use, the hexagonal block can be pulled upwards and completely removed via the fixed assembly. At this point, the operator can rotate the cross handle. The shape of the cross handle makes it easy for the operator to rotate manually, allowing for manual disassembly even in limited space. The operation is convenient and simple. Attached Figure Description
