Description

Technical Field

[0001] This utility model belongs to the technical field of stepped stainless steel round bars, specifically relating to a stepped stainless steel round bar that is easy to position and install. Background Technology

[0002] Stainless steel round bars, widely used in industrial applications, are standard cylindrical products made of stainless steel. Thanks to their excellent corrosion resistance, high strength, and good machinability, they occupy an important position in industries such as automotive parts manufacturing, aerospace precision instrument processing, hardware tool production, and chemical equipment construction. In automotive manufacturing, stainless steel round bars are commonly used to manufacture key components such as engine parts and exhaust systems.

[0003] However, currently available stainless steel round bars have significant limitations in practical applications. Existing methods primarily rely on welding for connection. While this ensures connection strength, the irreversible nature of welds makes disassembly extremely difficult during later maintenance and repairs. This not only consumes substantial manpower and resources but also risks damaging surrounding structures due to the high temperatures and mechanical stresses during disassembly. Furthermore, the lack of effective positioning structures during connection makes it difficult to precisely control the position and angle of the bars during installation, leading to deviations, low installation efficiency, and difficulty in guaranteeing the overall structural stability after connection. These problems severely restrict the convenience and flexibility of stainless steel round bars in engineering applications. Utility Model Content

[0004] The purpose of this utility model is to provide a stepped stainless steel round bar that is easy to position and install. It aims to solve the problem that in the existing technology, the connection method of the stainless steel round bar is mainly welding when the above-mentioned equipment is used. Although this method can ensure the connection strength, the irreversibility of the welded part makes it extremely difficult to disassemble the round bar during later maintenance and repair. This not only consumes a lot of manpower and material resources, but may also cause damage to the surrounding structure due to high temperature and mechanical stress during the disassembly process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stepped stainless steel round bar that is easy to position and install, comprising a mother bar and a daughter bar connected to one end of the mother bar, wherein a connecting rod is connected to one end of the mother bar and an insert rod is connected to one end of the daughter bar.

[0006] A positioning rod is connected to the inner wall of the connecting rod. A positioning hole is opened on the surface of the insert rod near the positioning rod. An adjusting wheel is connected to the opening on the surface of the connecting rod. A receiving block is connected to the tail end of the adjusting wheel. A rotating rod is connected to the opening on the surface of the insert rod. A locking spring is connected to the opening at one end of the rotating rod. A locking insert rod is connected to the other end of the locking spring. A gear disk is connected to the other end of the rotating rod. A right gear plate is connected to the surface of the gear disk. A right limiting block is connected to one side of the right gear plate. A lower wedge block is connected to the bottom end of the right gear plate.

[0007] As a preferred embodiment of this utility model of a stepped stainless steel round bar that is easy to position and install, the opening on one side of the connecting bar is inserted and connected with the insert bar, and the connecting bar is slidably connected with the positioning hole on the surface of the insert bar through a positioning rod.

[0008] As a preferred embodiment of this utility model of a stepped stainless steel round bar that is easy to position and install, the opening on one side of the adjusting wheel is hexagonal, the inner wall of the adjusting wheel is provided with a disassembly hole, and the locking spring and the locking rod form an elastic telescopic structure.

[0009] As a preferred embodiment of this utility model of a stepped stainless steel round bar that is easy to position and install, the locking rod has a hexagonal cross-section, and the locking rod and the opening on one side of the receiving block form an interlocking structure.

[0010] As a preferred embodiment of this utility model of a stepped stainless steel round bar that is easy to position and install, the gear disk and the right gear plate form a gear meshing structure, the right limiting block and the opening on the inner wall of the insert bar form a sliding connection structure, and the connecting bar has a slot on the inner wall near the lower wedge block.

[0011] As a preferred embodiment of this utility model of a stepped stainless steel round bar that is easy to position and install, the gear disk is connected to a left gear plate on the side opposite to the right gear plate, the gear disk is connected to a left limiting block on the side opposite to the left gear plate, and the top of the left limiting block is connected to an upper wedge block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention connects the connecting rod at one end of the female rod to the insert rod at one end of the male rod. This causes the positioning rod to slide into the positioning hole, thereby engaging the locking insert rod into the receiving block. A person then uses an Allen wrench to rotate the adjusting wheel on the surface of the connecting rod, which in turn rotates the gear disc. This causes the right and left gear plates to adjust up and down, resulting in the right and left limit blocks sliding along the openings on the inner wall of the insert rod. This causes the lower and upper wedge blocks to engage in the slots on the inner wall of the connecting rod, facilitating quick positioning and installation of the stepped stainless steel round bar and improving the ease of assembly and disassembly.

[0021] 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.

[0022] Please refer to Figures 1-5. The present invention provides the following technical solution: a stepped stainless steel round bar that is easy to position and install, including a mother bar 1 and a daughter bar 2 connected to one end of the mother bar 1. A connecting bar 3 is connected to one end of the mother bar 1, and an insert bar 4 is connected to one end of the daughter bar 2.

[0023] A positioning rod 5 is connected to the inner wall of the connecting rod 3. A positioning hole 6 is opened on the surface of the insert rod 4 near the positioning rod 5. An adjusting wheel 7 is connected to the opening on the surface of the connecting rod 3. A receiving block 8 is connected to the tail end of the adjusting wheel 7. A rotating rod 9 is connected to the opening on the surface of the insert rod 4. A locking spring 10 is connected to the opening at one end of the rotating rod 9. A locking insert rod 11 is connected to the other end of the locking spring 10. A gear disk 12 is connected to the other end of the rotating rod 9. A right gear plate 13 is connected to the surface of the gear disk 12. A right limit block 14 is connected to one side of the right gear plate 13. A lower wedge block 15 is connected to the bottom end of the right gear plate 13.

[0024] Preferably, the opening on one side of the connecting rod 3 is inserted and connected with the insert rod 4, and the connecting rod 3 is slidably connected with the positioning hole 6 on the surface of the insert rod 4 through the positioning rod 5.

[0025] In practical use, the positioning rod 5 is slid along the positioning hole 6 to facilitate the positioning and docking of the female rod 1 and the female rod 2, thereby improving the stability of the docking.

[0026] Preferably, the adjusting wheel 7 has a hexagonal opening on one side, and the inner wall of the adjusting wheel 7 has a disassembly hole. The locking spring 10 and the locking rod 11 form an elastic telescopic structure.

[0027] In practical use, during the docking process of the female rod 1 and the female rod 2, the locking rod 11 is easily driven to fit into the opening on one side of the receiving block 8, thereby facilitating the stable connection of the gear disk 12.

[0028] Preferably, the locking rod 11 has a hexagonal cross-section, and the locking rod 11 and the opening on one side of the receiving block 8 form a fitting structure.

[0029] In practical use, the locking rod 11 is fitted into the opening on one side of the receiving block 8. At this time, both the opening on one side of the receiving block 8 and the locking rod 11 are hexagonal structures, which ensures that when the adjusting wheel 7 is rotated, the rotating rod 9 is driven to rotate, while ensuring stability during the rotation process.

[0030] Preferably, the gear disk 12 and the right gear plate 13 form a gear meshing structure, the right limiting block 14 and the opening on the inner wall of the insert rod 4 form a sliding connection structure, and the connecting rod 3 has a slot 16 on the inner wall near the lower wedge block 15.

[0031] Preferably, a left gear plate 141 is connected to one side of the gear disk 12 opposite to the right gear plate 13, a left limiting block 142 is connected to the side of the gear disk 12 opposite to the left gear plate 141, and an upper wedge block 143 is connected to the top of the left limiting block 142.

[0032] In practical use, by rotating the gear disk 12, the right gear plate 13 and the left gear plate 141 are adjusted up and down. At the same time, the right limit block 14 and the left limit block 142 slide along the openings on the inner wall of the insert rod 4 to ensure the stability of the movement of the right gear plate 13 and the left gear plate 141. Then, the lower wedge block 15 and the upper wedge block 143 are both fitted into the slots 16 on the inner wall of the connecting rod 3, so as to facilitate the quick positioning and installation of the stepped stainless steel round rod.

[0033] The working principle of this utility model is as follows: By connecting the connecting rod 3 at one end of the female rod 1 with the insert rod 4 at one end of the female rod 2, the positioning rod 5 slides into the positioning hole 6. At this time, the locking spring 10 on the inner wall of the rotating rod 9 elastically rebounds, and the locking insert rod 11 is engaged in the receiving block 8. At this time, the operator controls the adjusting wheel 7 on the surface of the connecting rod 3 to rotate using an Allen wrench. The rotating rod 9 rotates, and at the same time, it drives the gear disk 12 at the other end of the rotating rod 9 to rotate. This causes the right gear plate 13 and the left gear plate 141 to adjust up and down, thereby causing the right limit block 14 and the left limit block 142 to slide along the openings on the inner wall of the insert rod 4. At this time, the lower wedge block 15 and the upper wedge block 143 are engaged in the slots 16 on the inner wall of the connecting rod 3. This facilitates the quick positioning and installation of the stepped stainless steel round bar. When disassembly is required, the adjusting wheel 7 is rotated in the opposite direction, and at the same time, the locking rod 11 is moved and retracted through the disassembly hole on the inner wall of the adjusting wheel 7, which improves the ease of disassembly and assembly of the stepped stainless steel round bar.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
