Description

Technical Field

[0001] This utility model relates to the field of stainless steel nut assemblies, and more particularly to a marine stainless steel nut assembly with a buffer washer. Background Technology

[0002] As is well known, marine stainless steel nuts with buffer washers are frequently used in the installation of existing ship hull components.

[0003] However, existing technologies often employ a separate design for the nut and washer. This makes it easy for the separate washer to fall off or be lost when ship operations frequently involve confined spaces (such as engine rooms) or outdoor environments. This not only delays assembly but also weakens the cushioning and vibration reduction effect due to missing washers or the use of incorrect substitutes, and may even lead to seal failure.

[0004] Furthermore, the separate type requires manual alignment of the washer before installing the nut, which is prone to misalignment when the ship is pitching or visibility is poor, further reducing the reliability of the cushioning and making it difficult to meet the efficient and stable connection requirements of ships. Therefore, this utility model proposes a marine stainless steel nut assembly with a cushioning washer. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a marine stainless steel nut assembly with a buffer washer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A marine stainless steel nut assembly with a buffer washer includes a nut head fixed to one end of a screw and a stainless steel nut body threaded onto the screw. The stainless steel nut body has a threaded hole, through which it is threadedly connected to the screw. A washer is located on the right side of the stainless steel nut body and is movably fitted onto the screw. Multiple buffer springs are fixedly connected between the washer and the stainless steel nut body in a ring, and a buffer piston rod is movably fitted inside each buffer spring. One end of the buffer piston rod is fixedly connected to the washer. The stainless steel nut body has multiple outer cylinder chambers, and a hydraulic cylinder is fixedly installed in each outer cylinder chamber. The other end of the buffer piston rod movably passes through the hydraulic cylinder and is fixedly connected to a piston head. A hydraulic return spring is fixedly connected between the piston head and the right inner wall of the hydraulic cylinder. The hydraulic cylinder has an inner cylinder chamber, and a buffer through hole is provided on the inner wall of the inner cylinder chamber. Both the inner and outer cylinder chambers contain hydraulic oil for hydraulic buffering.

[0008] The right port of the outer cylinder cavity is provided with an installation groove, in which a sealing end cap is fixedly installed, and a sealing gasket is provided on the left side of the sealing end cap.

[0009] As a further preferred embodiment, the number of buffer through holes is multiple, and the multiple buffer through holes are evenly distributed on the inner wall of the inner cylinder cavity.

[0010] As a further preferred embodiment, the piston head is provided with an annular groove on its circumference, and an annular rubber piston is fixedly sleeved in the annular groove. The piston head is slidably connected to the inner wall of the inner cylinder cavity through the annular rubber piston.

[0011] As a further preferred embodiment, the left inner wall of the outer cylinder cavity is provided with a mounting hole, and a sealing sleeve is fixedly installed in the mounting hole, through which the buffer piston rod slides.

[0012] As a further preferred option, the washer is made of stainless steel, and a rubber buffer ring is fixedly provided on the left side of the washer.

[0013] As a further preferred embodiment, the inner diameter of the washer is larger than the outer diameter of the screw.

[0014] The beneficial effects achieved by this utility model using the above structure are as follows:

[0015] 1. In this utility model, when the stainless steel nut body is threadedly locked to the screw rod through the screw hole on the nut body, the stainless steel nut body will cause the washer to abut against and fix the marine component to the nut head through the buffer spring and buffer piston rod; furthermore, through the elastic reaction of the hydraulic return spring and the buffer spring, the washer can be pushed in the opposite direction to abut against and fix the marine component, so as to ensure the stable installation and fixation of the marine component; at the same time, under the elastic reaction of the hydraulic return spring and the buffer spring, the threaded connection between the stainless steel nut body and the screw rod can also be ensured to be tighter, and the thread is not easy to loosen.

[0016] 2. In this utility model, when marine components vibrate during navigation, a rubber buffer ring is set on the washer. The rubber buffer ring can absorb a certain amount of vibration energy. At the same time, during the vibration process, the buffer spring is compressed and buffered, and the hydraulic buffering cooperation between the buffer piston rod and the piston head and the hydraulic oil in the inner cylinder cavity can further play a buffering and vibration reduction effect, thereby ensuring a better overall vibration reduction effect.

[0017] In summary, this marine stainless steel nut assembly with a buffer washer not only ensures a tighter threaded connection between the stainless steel nut body and the screw, preventing thread loosening, but also ensures excellent vibration damping for the entire assembly. Furthermore, the connection between the washer and the stainless steel nut body is achieved through a buffer spring and a buffer piston rod, avoiding the washer loss or detachment issues common in existing technologies where the nut and washer are separated. This ensures smooth operation and significantly meets user needs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A marine stainless steel nut assembly with a buffer washer includes a nut head 1 fixed to one end of a screw 2, and a stainless steel nut body 3 threadedly connected to the screw 2. The stainless steel nut body 3 has a threaded hole 301, through which it is threadedly connected to the screw 2. A washer 4 is located on the right side of the stainless steel nut body 3 and is movably fitted onto the screw 2. Multiple evenly arranged buffer springs 5 ​​are fixedly connected between the washer 4 and the stainless steel nut body 3. A buffer piston rod 6 is movably fitted inside each buffer spring 5, and one end of the buffer piston rod 6 is fixedly connected to the washer 4. The device has multiple outer cylinder chambers 300, and a hydraulic cylinder 8 is fixedly installed in each outer cylinder chamber 300. The other end of the buffer piston rod 6 is movably inserted into the hydraulic cylinder 8 and fixedly connected to a piston head 7. A hydraulic return spring 9 is fixedly connected between the piston head 7 and the right inner wall of the hydraulic cylinder 8. The hydraulic cylinder 8 has an inner cylinder chamber 800, and a buffer through hole 801 is provided on the inner wall of the inner cylinder chamber 800. Both the inner cylinder chamber 800 and the outer cylinder chamber 300 are provided with hydraulic oil for hydraulic buffering. The right port of the outer cylinder chamber 300 is provided with a mounting groove 302, and a sealing end cover 11 is fixedly installed in the mounting groove 302. A sealing gasket is provided on the left side of the sealing end cover 11.

[0025] The buffer through holes 801 are provided in multiple quantities and are evenly distributed on the inner wall of the inner cylinder cavity 800. The piston head 7 has an annular groove on its circumference, and an annular rubber piston 701 is fixedly sleeved in the annular groove. The piston head 7 is slidably connected to the inner wall of the inner cylinder cavity 800 through the annular rubber piston 701.

[0026] The outer cylinder cavity 300 has a mounting hole on its left inner wall, and a sealing sleeve 10 is fixedly installed in the mounting hole. The buffer piston rod 6 slides through the sealing sleeve 10. The washer 4 is made of stainless steel, and a rubber buffer ring 401 is fixedly installed on the left side of the washer 4.

[0027] The inner diameter of washer 4 is larger than the outer diameter of screw 2.

[0028] like Figure 1-4 As shown, this marine stainless steel nut assembly with a buffer washer, through the cooperation of the stainless steel nut body 3 and washer 4 with the nut head 1, allows marine components to be fitted onto the screw 2 through the mounting hole and fixed between the washer 4 and the nut head 1 on the left side of the nut body 3. During installation, when the stainless steel nut body 3 is threadedly tightened with the screw 2 through the screw hole 301 on the stainless steel nut body 3, the stainless steel nut body 3, through the buffer spring 5 and buffer piston rod 6, causes the washer 4 to press against and fix the marine component against the nut head 1. During the process of the washer 4 pressing against the marine component, the stainless steel nut body 3 and the screw 2 will... During the continuous tightening of the threads, the buffer spring 5 is relatively compressed, and at the same time, the buffer piston rod 6 and piston head 7 are relatively compressed against the hydraulic return spring 9. After the stainless steel nut body 3 and the screw 2 are locked and fixed, the hydraulic return spring 9 and the buffer spring 5 both generate elastic reaction force, which can further push the washer 4 to resist and fix the marine parts, so as to ensure the stable installation and fixation of the marine parts. At the same time, under the elastic reaction force of the hydraulic return spring 9 and the buffer spring 5, the threaded connection between the stainless steel nut body 3 and the screw 2 can be made tighter, and the threads are less likely to loosen.

[0029] When marine components vibrate during navigation, a rubber buffer ring 401 is installed on the washer 4. The rubber buffer ring 401 can absorb a certain amount of vibration energy. Simultaneously, during vibration, the buffer spring 5 is compressed for cushioning, and the buffer piston rod 6 and piston head 7 provide hydraulic buffering against the hydraulic oil in the inner cylinder 800, further enhancing the damping effect and ensuring better overall vibration reduction. Furthermore, the washer 4 and the stainless steel nut body 3 are connected by the buffer spring 5 and the buffer piston rod 6, avoiding the common problem of washer loss due to the separate design of the nut and washer in existing technologies. This ensures smooth subsequent use and greatly meets user needs.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
