Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, and in particular to a high-frequency wear-resistant composite rod. Background Technology

[0002] In recent years, emission regulations have become increasingly stringent, and natural gas, as a clean energy source, has been widely used to replace fuels. The research and development and production of natural gas engines have been increasing, and the supporting natural gas carburetors and secondary pressure reducing valves have also seen rapid development. In the actual use of gas engines, equipment such as secondary pressure reducing valves will face harsh working environments, such as high-frequency vibration. This places higher demands on the material, wear resistance, and service life of components. Traditional components are difficult to meet these requirements. Therefore, it is necessary to develop a high-frequency wear-resistant composite rod to improve the performance and reliability of gas valves, extend their service life, and ensure that gas valves can work stably and safely under harsh conditions.

[0003] If the composite rod lacks a wear-resistant structure during its use inside the gas valve, its service life will be reduced. Utility Model Content

[0004] The purpose of this invention is to provide a high-frequency wear-resistant composite rod. By using a combination of a groove in the groove and a high-wear-resistant roller, the friction loss of the composite rod during relative motion can be significantly reduced. This not only extends the service life of the component but also reduces the heat and noise generated by friction, thereby improving the working efficiency and user experience of the composite rod.

[0005] To achieve the above objectives, a high-frequency wear-resistant composite rod is provided, comprising: a rod body, the outer surface of which is provided with a threaded groove, the inner surface of which is threaded with threaded teeth, and a sleeve rod fixedly connected to the outer surface of which is threaded teeth. The outer surface of the sleeve rod has four mating grooves, the inner surface of each of the four mating grooves is provided with a rolling groove, and positioning posts are fixedly connected to the left and right sides of the inner walls of each of the four mating grooves. A high-performance spring is rotatably connected to the outer surface of each positioning post, and the high-performance spring abuts against the inner surface of the mating groove. An installation groove is provided inside the high-performance spring, and fixing posts are fixedly connected to the left and right sides of the inner wall of the installation groove. A high-wear-resistant roller is rotatably connected to the outer surface of each fixing post. This design ensures a stable connection and flexible movement of the composite rod, and the high-wear-resistant roller, in conjunction with the spring, reduces frictional loss.

[0006] According to the aforementioned high-frequency wear-resistant composite rod, the dimensions of the high-wear-resistant roller and the groove are matched, and the dimensions of the high-performance spring piece and the mating groove are matched. This dimensional matching ensures the precision of component fit, resulting in smooth movement of the composite rod and reducing vibration and wear.

[0007] According to the aforementioned high-frequency wear-resistant composite rod, the high-performance spring sheet has an inverted V-shaped cross-section, and the number of high-performance spring sheets corresponds to the number of mating grooves. The inverted V-shaped spring sheets have good elasticity, and the corresponding number ensures uniform force distribution, enhancing the buffering and shock absorption performance of the composite rod.

[0008] According to the aforementioned high-frequency wear-resistant composite rod, a limiting post is fixedly connected to the outer surface of the rod body, and the limiting post and the upper surface of the sleeve rod abut against each other. The limiting post restricts the upward movement of the sleeve rod, ensuring the stability of the composite rod structure and preventing damage from excessive displacement of components.

[0009] According to the aforementioned high-frequency wear-resistant composite rod, a truncated cone is fixedly connected to the lower surface of the rod body, and the truncated cone has a structure that is larger at the top and smaller at the bottom. The truncated cone structure facilitates guidance and load transfer, prevents component misalignment, and improves the operational reliability of the composite rod.

[0010] According to the aforementioned high-frequency wear-resistant composite rod, an abutment post is fixedly connected to the outer surface of the rod body, and the abutment post is located above a limiting post. The abutment post and the limiting post cooperate to provide bidirectional limiting, precisely controlling the stroke of the sleeve rod and extending the service life of the composite rod.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] This utility model incorporates threaded teeth, a connecting rod, a mating groove, a roller groove, a positioning post, a high-performance spring, a mounting groove, a fixing post, and a high-wear-resistant roller. Through the mating groove's design with the high-wear-resistant roller, the frictional loss of the composite rod during relative movement is significantly reduced. This not only extends the service life of the components but also reduces heat and noise generated by friction, thereby improving the composite rod's working efficiency and user experience.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model discloses a high-frequency wear-resistant composite rod, comprising: a rod body 1, the outer surface of which is provided with a threaded groove 6, the threaded groove 6 providing a base for threaded teeth 7 to be screwed on, and the axial positioning and circumferential fixation of the sleeve rod 2 and the rod body 1 are achieved through threaded connection; the inner surface of the threaded groove 6 is threadedly connected with threaded teeth 7, the threaded teeth 7 converting the rotational motion of the sleeve rod 2 into axial displacement through threaded engagement, and simultaneously serving as a force transmission medium between the sleeve rod 2 and the rod body 1; the outer surface of the threaded teeth 7 is fixedly connected to the sleeve rod 2, and the sleeve rod 2 is connected through... The threaded tooth 7 forms a detachable connection with the rod body 1. The mating groove 8 on its outer surface provides an installation carrier for subsequent components. Four mating grooves 8 are evenly distributed around the outer surface of the sleeve rod 2, providing installation space for components such as the high-performance spring 10 and positioning post 9. Radial limiting is achieved through structural fit. The inner surfaces of all four mating grooves 8 are provided with rolling grooves 14, which are sized to match the high-wear-resistant roller 13, providing a guide track for the roller's rolling and reducing frictional loss during relative movement of the components. Positioning posts 9 are fixedly connected to both sides of the wall. The positioning posts 9 serve as the rotation fulcrum of the high-performance spring 10, limiting the radial movement range of the spring within the mating groove 8 to ensure installation accuracy. The high-performance spring 10 is rotatably connected to the outer surface of the positioning posts 9, and the high-performance spring 10 abuts against the inner surface of the mating groove 8. The high-performance spring 10 is rotatably installed through the positioning posts 9, and its contact with the inner wall of the mating groove 8 provides elastic preload, enhancing the stability of the component connection. The high-performance spring 10 has an installation groove 11 inside, which serves as a fixing post. The high-wear-resistant roller 12 and the high-wear-resistant roller 13 provide installation space. The rigid connection between the roller assembly and the spring is achieved through structural nesting. The left and right sides of the inner wall of the mounting groove 11 are fixedly connected to the fixing column 12. The fixing column 12 serves as the rotation axis of the high-wear-resistant roller 13, ensuring that the roller rotates stably in the mounting groove 11 and transmitting radial load. The high-wear-resistant roller 13 is rotatably connected to the outer surface of the fixing column 12. The high-wear-resistant roller 13 is linked with the high-performance spring 10 through the fixing column 12. Its outer surface contacts the rolling groove 14, converting sliding friction into rolling friction to reduce wear.

[0023] The dimensions of the high-wear-resistant roller 13 and the groove 14 are matched. This matching ensures precise rolling of the roller within the groove 14, preventing wobbling due to excessive clearance or jamming due to insufficient clearance, thus improving motion stability. The dimensions of the high-performance spring 10 and the mating groove 8 are matched. This matching ensures that the spring can rotate freely within the groove 8 and generate effective elastic deformation through inner wall contact, achieving adaptive load adjustment. The cross-section of the high-performance spring 10 is inverted V-shaped. This inverted V-shaped cross-section gives the spring unique elastic mechanical properties, enabling it to produce symmetrical deformation under pressure, uniformly distributing the load and enhancing fatigue resistance. The number of high-performance springs 10 corresponds to the number of mating grooves 8. This one-to-one matching configuration ensures uniform circumferential force on the sleeve rod 2, preventing issues caused by missing components. To address the issue of uneven load and improve the overall structural strength, a limiting post 4 is fixedly connected to the outer surface of the rod body 1. The limiting post 4 and the upper surface of the sleeve rod 2 abut against each other. By contacting the upper surface of the sleeve rod 2, the limiting post 4 restricts the upward movement of the sleeve rod 2 along the axial direction of the rod body 1, thus achieving a mechanical limiting function. A contact frustum 5 is fixedly connected to the lower surface of the rod body 1. The contact frustum 5 has a structure that is larger at the top and smaller at the bottom. The conical structure of the contact frustum 5 provides guidance when the sleeve rod 2 moves downward. At the same time, it uniformly transmits axial load by increasing the contact area. A contact post 3 is fixedly connected to the outer surface of the rod body 1. The contact post 3 is located above the limiting post 4. The contact post 3 serves as a stop at the extreme position of the upward movement of the sleeve rod 2. It cooperates with the limiting post 4 to form a bidirectional axial limiting, ensuring that the movement range of the sleeve rod 2 is controllable.

[0024] Working principle: First, the threaded teeth 7 are screwed into the threaded grooves 6 on the outer surface of the rod body 1. The initial connection between the sleeve rod 2 and the rod body 1 is achieved through thread engagement. The threaded teeth 7 serve as the force transmission medium, ensuring the axial positioning and circumferential fixation of the sleeve rod 2. Four high-performance spring pieces 10 are rotatably connected to the inner walls of the four mating grooves 8 on the outer surface of the sleeve rod 2 through positioning pins 9. The inverted V-shaped structure of the spring piece cross-section causes it to abut against the inner wall of the mating groove 8, generating an elastic preload. In the mounting groove 11 of the high-performance spring piece 10, a high wear-resistant roller 13 is installed through the fixing pin 12. The roller size is adapted to the rolling groove 14 on the inner surface of the mating groove 8, ensuring that the roller can roll precisely in the rolling groove 14, converting sliding friction into rolling friction. The limiting pin 4 on the outer surface of the rod body 1 abuts against the upper surface of the sleeve rod 2, limiting the maximum stroke of the sleeve rod 2 moving upward along the axial direction of the rod body 1. The abutting pin 3 is located above the limiting pin 4, serving as the limit stop for the upward movement of the sleeve rod 2, and is shaped with the limiting pin 4. The sleeve rod 2 is axially limited in both directions. The abutting frustum 5 (with a larger upper part and a smaller lower part) on the lower surface of the rod body 1 provides guidance when the sleeve rod 2 moves downward. The axial load is uniformly transmitted through the conical contact. When the sleeve rod 2 is subjected to axial load, the high-performance spring 10 undergoes elastic deformation through the rotation fulcrum of the positioning post 9. The inverted V-shaped cross section makes it uniformly distribute the load and enhances the fatigue resistance. The high wear-resistant roller 13 moves in conjunction with the spring and rolls in the groove 14, transmitting the radial load to the spring through the fixed post 12. At the same time, it reduces the friction loss between components. The threaded teeth 7 continuously maintain the connection stability between the sleeve rod 2 and the rod body 1 through the threaded connection, ensuring that the load is transmitted to the main body of the rod body 1 through the threaded pair. Rotating the sleeve rod 2 in the opposite direction, the sleeve rod 2 is disassembled from the rod body 1 through the engagement and disengagement of the threaded teeth 7 and the threaded groove 6. The worn high wear-resistant roller 13 or the high-performance spring 10 can be replaced separately. The component maintenance can be completed quickly through the rotational connection structure of the positioning post 9 and the fixed post 12.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
