DETAILED DESCRIPTION

[0022] The technical scheme of the utility model will be further concretely described below by specific embodiments, and the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Embodiment 1: refer to Figures 1 to 6A square and inclined jack structure, the main rod 1 serves as the base of the structure, its design is very critical. One end of the main rod 1 is specially designed as the main rod connecting end 4, which not only provides a connection point with the jack, but also precisely matches the jack's stepped surface 16 through the main rod's stepped surface 17, forming a solid connection. This stepped surface design not only enhances the stability of the connection, but also provides good alignment and positioning, ensuring that the jack and the main rod maintain an accurate positional relationship even under high loads.

[0024] The end of the jack 6, namely the jack connecting end 2, closely matches the main rod connecting end 4, which not only ensures the stability of the structure, but also allows the jack 6 to move freely on the main rod to adapt to different working conditions. The design of the jack connecting end 2 usually includes precise tolerances to ensure seamless docking with the main rod 1 connecting end 4.

[0025] The other side of the jack 6 is the jack inclined surface 7, the design of this inclined surface is crucial as it determines the support angle and strength of the jack. The jack inclined surface 7 is usually designed with a special angle, which is carefully calculated to ensure that when the jack is under pressure, the force can be evenly distributed, thereby providing maximum stability and support. This design also helps to reduce the local stress concentration that may occur on the jack under high load, prolonging the service life of the jack.

[0026] The adjacent layout of the jack inclined surface 7 and the top block 18 further enhances the structural strength of the jack. The top block 18 is a key part of the jack, its design and material selection directly affect the overall performance of the jack. One side of the top block 18 is the tip 14 of the jack, which is the front line of the jack in contact with the outside world and plays a role. The design of the jack tip 14 must be sharp enough to facilitate penetration or lifting of objects, while also having sufficient strength to withstand the huge force transmitted from the top block 18.

[0027] The design of the top block 18 usually uses high-strength materials to ensure that it will not deform or be damaged under heavy pressure. The shape and size of the top block are also carefully designed to ensure that when the jack tip 14 is subjected to force, the force can be effectively transmitted to the top block and evenly distributed to other parts of the jack through the top block. This design helps to improve the working efficiency of the jack while reducing the risk of damage caused by force concentration.

[0028] In practical applications, the combination of the jack 6 and the top block 18 can provide strong support and lifting capacity. Whether in mechanical manufacturing, construction or other fields that require precise control and strong support, this square and inclined jack structure can play an important role. Through careful design and manufacturing, the combination of the jack 6 and the top block 18 can provide stable, reliable and durable working performance.

[0029] To enhance the stability of the structure, a connection hole 3 is designed at the top rod connection end 2, and a first fastener 5 can be installed in this hole. The function of the first fastener 5 is to firmly fix the top rod in place, preventing loosening under high load or vibration conditions. This fastening design ensures the reliability and safety of the top rod in long-term use.

[0030] At the junction of the top rod bevel 7 and the top block 18, a linear groove 9 is designed. The linear groove 9 not only increases the strength of the top rod, but also may help the top rod slide or position during operation. The design of the linear groove 9 makes the top rod more stable when subjected to lateral force, reducing damage caused by friction or wear.

[0031] The edge of the top block 18 is designed with a ring groove 18, which surrounds the top block 18 to form a continuous groove structure. This design not only enhances the structural strength of the top block, but also may facilitate the flow of liquid or gas if these elements are involved in the structure. The ring groove 18 is connected to the linear groove 9, and this design makes the top block more flexible during operation, while also providing additional channels that may be used for functions such as heat dissipation, lubrication, or drainage.

[0032] Example 2: Reference Figures 1 to 6 A square and oblique top rod structure, in which the main rod 1 serves as the foundation of the entire structure, is of great importance. One end of the main rod 1 is specially designed as the main rod connection end 4, which not only serves as the connection point of the top rod, but also precisely matches the stepped surface 16 of the top rod through the stepped surface 17 of the main rod, thereby forming a firm connection. This stepped surface design not only enhances the stability of the connection, but also ensures good alignment and positioning, so that the top rod and the main rod can maintain a precise positional relationship under high load conditions.

[0033] One end of the top rod 6, namely the top rod connection end 2, is closely combined with the main rod connection end 4. This close fit not only ensures the stability of the structure, but also allows the top rod 6 to move freely on the main rod to adapt to different working conditions. The design of the top rod connection end 2 usually has precise tolerances to ensure seamless docking with the main rod connection end 4.

[0034] The other side of the top rod 6 is the top rod bevel 7, which is of great importance because it determines the support angle and the force exerted by the top rod. The top rod bevel 7 adopts a special angle design, which is calculated precisely to ensure that when the top rod is subjected to pressure, the force can be evenly distributed, thereby providing maximum stability and support force. This design also effectively reduces the local stress concentration that may occur under high load, prolonging the service life of the top rod.

[0035] The oblique surface 7 of the ejector rod and the adjacent placement of the ejector block 18 further enhance the structural strength of the ejector rod. The ejector block 18 is a crucial component of the ejector rod, and its design and material selection directly impact the overall performance of the ejector rod. One side of the ejector block 18 is the tip 14 of the ejector rod, which is the front line of contact and action with the outside world. The design of the ejector rod tip 14 must be sharp enough to facilitate penetration or lifting of objects, while having sufficient strength to withstand the immense force transmitted from the ejector block 18.

[0036] The design of the ejector block 18 usually adopts high-strength materials to ensure that it will not deform or be damaged under heavy pressure. The shape and size of the ejector block are carefully designed to ensure that when the ejector rod tip 14 is subjected to force, the force can be effectively transmitted to the ejector block and evenly dispersed to other parts of the ejector rod through the ejector block. This design helps to improve the working efficiency of the ejector rod while reducing the risk of damage caused by force concentration.

[0037] In practical applications, the combination of the ejector rod 6 and the ejector block 18 can provide strong support and lifting capacity. Whether in mechanical manufacturing, construction, or other fields that require precise control and strong support, this oblique ejector rod structure can play an important role. Through careful design and manufacturing, the combination of the ejector rod 6 and the ejector block 18 can provide stable, reliable and durable working performance.

[0038] In order to enhance the stability of the structure, a connecting hole 3 is designed at the connecting end 2 of the ejector rod, in which a first fastener 5 can be installed. The function of the first fastener 5 is to firmly fix the ejector rod, preventing it from loosening under high load or vibration conditions. This fastening design ensures the reliability and safety of the ejector rod in long-term use.

[0039] At the junction of the ejector rod oblique surface 7 and the ejector block 18, a linear groove 9 is designed. This linear groove 9 adopts a linear structure, not only increasing the strength of the ejector rod, but also possibly facilitating the sliding or positioning of the ejector rod during operation. The design of the linear groove 9 makes the ejector rod more stable when subjected to lateral forces, reducing damage caused by friction or wear.

[0040] The edge of the ejector block 18 is designed with a ring groove 18, which surrounds the ejector block 18, forming a continuous groove structure. Such a design not only enhances the structural strength of the ejector block, but also may facilitate the flow of liquids or gases, especially when these elements are involved in the structure. The ring groove 18 is connected to the linear groove 9, and this design makes the ejector block more flexible during operation, while providing additional channels that may be used for functions such as heat dissipation, lubrication or drainage.

[0041] The ring groove 18 surrounds the top block 18, enhancing the structural strength of the top block. It is also ingeniously connected with the lower platform 11 of the top block. This design divides the functional area of the top block into upper and lower parts, making the connection between the lower platform 11 and the upper platform 13 of the top block adopt an arc surface 12. This design not only provides a smooth transition, but also helps to disperse the stress generated when the top block is under stress, reducing potential stress concentration points. The design of the arc surface 12 takes into account the aesthetic factor, making the appearance of the entire top block more smooth and harmonious, improving the aesthetic appearance of the product.

[0042] The lower platform 11 of the top block, as part of the top block 18, is crucial to the function of the entire square and inclined top rod structure. The lower platform 11 of the top block not only can be used to support or fix other mechanical components, but also can be used as a force transmission point to effectively transmit the force generated by the top rod tip 14 to other parts of the structure. The design of the arc surface 12 makes the combination of the lower platform 11 and the upper platform 13 of the top block more stable, while also providing better mechanical properties, enhancing the overall stability and durability of the top block.

[0043] One end of the main rod 1 is provided with a fastening hole 19, which is designed to install the second fastener 15. The position and size of the fastening hole 19 are carefully calculated to ensure that the second fastener 15 can be correctly installed and play its role. The second fastener 15 can be a bolt, screw or other type of fastener, whose main function is to fix the main rod 1 in place, ensuring that the main rod 1 does not shift or rotate when the top rod 6 exerts force.

[0044] The installation of the second fastener 15 not only improves the stability of the entire square and inclined top rod structure, but also enhances its reliability when subjected to repeated or periodic loads. The use of the fastening hole 19 and the second fastener 15 provides additional safety for the square and inclined top rod structure, especially in environments that need to withstand high loads or vibrations. This design also allows for quick disassembly and maintenance, making the square and inclined top rod structure more suitable for applications that require frequent inspection and maintenance.

[0045] In summary, the connection design of the ring groove 18 and the lower platform 11 of the top block, as well as the use of the fastening hole 19 on the main rod 1 and the second fastener 15, together improve the functionality and reliability of the square and inclined top rod structure, making it better adapt to various complex working environments. These design details not only enhance the stability and durability of the structure, but also improve its flexibility in actual operation and the convenience of maintenance, reflecting the careful consideration and attention to detail in engineering design.

[0046] Example 3: Refer to Figures 1 to 6A square and inclined jack rod structure, one end of the main rod 1 is the main rod connecting end 4, which is connected with the jack rod and also realizes precise matching with the jack rod's stepped surface 16 through the main rod's stepped surface 17 on it, building a solid connection point. The design of this stepped surface not only improves the stability of the connection, but also ensures that the jack rod and the main rod can maintain accurate relative positions even when bearing heavy loads. One end of the jack rod 6, namely the jack rod connecting end 2, realizes close combination with the main rod connecting end 4. This close combination not only provides stability for the entire structure, but also allows the jack rod 6 to slide freely on the main rod to adapt to changing working conditions. The design of the jack rod connecting end 2 usually has fine tolerances, ensuring a seamless fit with the main rod connecting end 4.

[0047] The other end of the jack rod 6 is the jack rod inclined surface 7, the design of this inclined surface is crucial to the function of the entire jack rod, as it determines the support angle and force exertion of the jack rod. The jack rod inclined surface 7 is designed with a special angle, which is calculated precisely to ensure that when the jack rod bears pressure, the force can be evenly distributed, thereby providing maximum stability and support force. This design also effectively reduces the local stress concentration that may occur under high load, prolonging the service life of the jack rod. The adjacent layout of the jack rod inclined surface 7 and the top block 18 further enhances the structural strength of the jack rod. The top block 18 is a key component of the jack rod, and its design and material selection directly affect the overall performance of the jack rod. One side of the top block 18 is the jack rod tip 14, which is the key part of the jack rod that contacts the outside world and functions. The design of the jack rod tip 14 must be sharp enough to penetrate or lift objects, while also having enough strength to withstand the huge force transmitted from the top block 18.

[0048] The top block 18 is usually made of high-strength materials to ensure that it will not deform or be damaged when bearing heavy pressure. The shape and size of the top block are carefully designed to ensure that when the jack rod tip 14 is subjected to force, the force can be effectively transmitted to the top block and evenly distributed to other parts of the jack rod. This design helps to improve the working efficiency of the jack rod while reducing the risk of damage caused by force concentration.

[0049] In practical applications, the coordinated work of the jack rod 6 and the top block 18 can provide strong support and lifting capacity. Whether in mechanical manufacturing, construction or other fields that require precise control and strong support, this square and inclined jack rod structure can play a key role. Through careful design and manufacturing, the combination of the jack rod 6 and the top block 18 can provide stable, reliable and durable working performance.

[0050] To enhance the stability of the structure, a connection hole 3 is designed at the top rod connection end 2, in which a first fastener 5 can be installed. The function of the first fastener 5 is to firmly fix the top rod, preventing loosening under high load or vibration conditions. This fastening design ensures the reliability and safety of the top rod in long-term use.

[0051] At the connection between the top rod bevel 7 and the top block 18, a linear groove 9 is designed. This linear groove 9 adopts a one-letter structure, not only increasing the strength of the top rod, but also possibly helping the top rod to slide or position during operation. The design of the linear groove 9 makes the top rod more stable when subjected to lateral force, reducing damage caused by friction or wear. The edge of the top block 18 is designed with a ring groove 18, which surrounds the top block 18, forming a continuous groove structure. Such design not only enhances the structural strength of the top block, but also may facilitate the flow of liquid or gas, especially when these elements are involved in the structure. The ring groove 18 is connected with the linear groove 9.

[0052] One side of the top rod 6 is specially designed with a protrusion 8, which adopts a square structure. This square protrusion 8 design has multiple effects, first, it increases the structural strength of the top rod 6, providing additional support points, making the top rod more stable when subjected to pressure. Second, the design of the protrusion 8 can also serve as an interface for the connection of the top rod 6 with other mechanical components, for example, it can match with the corresponding groove or other square structure to achieve precise docking and fixation. In addition, the square structure of the protrusion 8 also facilitates positioning and grabbing during automated assembly, improving assembly efficiency and accuracy.

[0053] The exposed side of the top block 18 is specially designed with a top block bevel 20, which is connected with the ejection bevel 21. The design of the top block bevel 20 takes into account the mechanical requirements of the top block 18 during ejection, and the bevel 20 provides a smooth transition area, making the top block more smooth when ejecting objects, reducing resistance and friction. This design helps to improve the ejection efficiency of the top block, especially in applications that require rapid or frequent ejection.

[0054] The connection design of the top block bevel 20 and the ejection bevel 21 further optimizes the mechanical properties of the top block 18. The ejection bevel 21, as an extension of the top block bevel 20, not only continues to provide a smooth ejection path, but also increases the contact area between the top block 18 and the ejected object, which helps to disperse the ejection force, reduce wear on the top block, and improve the stability of the ejection process. In addition, the design of the ejection bevel 21 can also reduce the vibration of the top block during ejection, improving the accuracy and reliability of the ejection action.

[0055] In summary, the design of the protrusion 8 and the top block inclined surface 20 and the ejection inclined surface 21 collectively enhances the functionality and efficiency of the square and inclined ejector rod structure. These designs not only enhance the structural strength and stability of the ejector rod and the top block, but also improve the smoothness and efficiency of the ejection process, making the entire square and inclined ejector rod structure more suitable for high-demand industrial applications such as precision machinery manufacturing, automated assembly lines, and other scenarios that require precise control and strong support.

[0056] The present application is not limited to the details of the foregoing exemplary embodiments and this application can be carried out in other specific ways without departing from the spirit or essential characteristics of the application.
