Abstract
Description
Technical Field
[0001] This utility model relates to the field of straight umbrella center rods, specifically to a single-axis color electroplated straight umbrella center rod. Background Technology
[0002] The umbrella's central rod is produced through a combination of segmented insertion, central rod cutting, and die casting, requiring multiple processes for meticulous processing and batch correction.
[0003] According to the search, a multi-fold umbrella central rod with announcement number CN211021301U includes an inner tube, an outer tube, and at least one central tube. The inner tube, central tube, and outer tube are coaxially sleeved in sequence. A first rivet is fixedly connected to the outer wall of the inner tube and the central tube near the outer tube. A first rivet rod is fixedly connected to the end face of the first rivet near the central rod. The first rivet rod is inserted into the inner tube or the central tube. A second rivet is fixedly connected to the inner wall of the outer tube and the central tube near the inner tube. The end face of the first rivet near the outer tube abuts against the end face of the second rivet near the inner tube.
[0004] However, the existing multi-fold umbrella stick has certain drawbacks in use. Although it can move the middle and outer tubes up and down and provide elastic limits for them, the lack of limits during the up-and-down movement of the middle and outer tubes results in poor stability. After prolonged pulling, the bottom of the middle and outer tubes may collide and rub against the inner walls of adjacent tubes, causing damage. Furthermore, the spring has strong elasticity, making it difficult to stably lock the middle and outer tubes, which may cause the tubes to sway during use and affect the normal use of the umbrella. Utility Model Content
[0005] In view of the problems existing in the main bar of the current multi-fold umbrella, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a single-axis color-plated straight umbrella center rod, which solves the problem that although the umbrella center rod can realize the up and down movement of the middle tube and the outer tube and the elastic limit of the middle tube and the outer tube during use, the middle tube and the outer tube lack limit when pulling up and down, resulting in poor stability of the up and down movement of the middle tube and the outer tube. After long-term pulling, the bottom of the middle tube and the outer tube may collide and rub against the inner wall of the adjacent tube, resulting in damage to the middle tube and the outer tube. In addition, the spring has strong elasticity, making it difficult to stably lock the middle tube and the outer tube. As a result, the tube body may shake during use, thus affecting the normal use of the umbrella.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A single-axis color-plated straight umbrella rod includes a lower rod body, an upper rod body, and multiple strip-shaped limiting plates. The side walls of both the lower and upper rod bodies are fixedly coated with an electroplated layer. The lower rod body has a lower strip-shaped opening inside, and the upper rod body has an upper strip-shaped opening inside. The upper rod body movably passes through the lower strip-shaped opening. Multiple strip-shaped limiting plates are fixedly disposed on the side walls of the upper rod body. The inner wall of the lower rod body has multiple strip-shaped limiting channels. Each strip-shaped limiting plate slidably fits into the interior of a corresponding strip-shaped limiting channel. A screw is movably sleeved inside the lower rod body, and a knob is fixedly disposed at one end of each screw. The upper rod body has two threaded grooves inside, each threaded groove matching the other end of the screw.
[0009] Preferably, the screw has an annular limiting plate fixedly sleeved on its wall, and the annular limiting plate is disposed on one side of the inner wall of the lower rod.
[0010] Preferably, each of the strip-shaped limiting plates is a hollow plate, and each of the strip-shaped limiting plates is a stainless steel plate.
[0011] Preferably, both the lower rod and the upper rod are stainless steel rods.
[0012] Preferably, a gripping rod is fixedly provided at the bottom of the lower rod, and the gripping rod has multiple anti-slip threads on its wall.
[0013] Preferably, one side of each of the strip-shaped limiting plates is arc-shaped.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] This invention, through the design of an electroplated layer, multiple strip-shaped limiting plates, and a screw, prevents paint peeling from the outer surfaces of the lower and upper umbrella rods by electroplating. When the user pulls the upper umbrella rod up and down, the multiple strip-shaped limiting plates can slide up and down within their corresponding grooves, effectively limiting the movement of the upper umbrella rod at multiple angles. This improves the stability of the upper umbrella rod during pulling and prevents the bottom of the upper umbrella rod from colliding and rubbing against the inner wall of the lower umbrella rod. Turning the knob causes one end of the screw to be threaded into the threaded groove, thereby locking the upper umbrella rod and preventing it from shaking during use, which would affect the normal use of the umbrella.
[0016] This invention features an annular limiting plate positioned on one side of the inner wall of the lower rod and fixedly sleeved onto the rod wall of the screw. When the screw rotates, it drives the annular limiting plate to rotate synchronously. As the annular limiting plate moves and adheres to the inner wall of the lower rod, it prevents the screw from falling off.
[0017] This utility model features a grip rod and multiple anti-slip threads. The grip rod is fixedly mounted on the bottom of the lower body, making it convenient for the user to hold the umbrella. The multiple anti-slip threads increase the friction between the user's hand and the grip rod, and improve the stability of the user holding the umbrella. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model discloses a single-axis color electroplated straight umbrella center rod.
[0027] This utility model provides, for example Figure 1-4The single-axis color electroplated straight umbrella rod shown includes a lower rod body 1, an upper rod body 2, and multiple strip-shaped limiting plates 3. Electroplating layers 4 are fixedly disposed on the side walls of both the lower rod body 1 and the upper rod body 2. A lower strip-shaped opening 5 is formed inside the lower rod body 1, and an upper strip-shaped opening 6 is formed inside the upper rod body 2. The upper rod body 2 is movably inserted into the lower strip-shaped opening 5. Multiple strip-shaped limiting plates 3 are fixedly disposed on the side walls of the upper rod body 2. Multiple strip-shaped limiting channels are formed on the inner wall of the lower rod body 1, and each strip-shaped limiting plate 3 slides and fits into the corresponding strip-shaped limiting channel. A screw 7 is movably sleeved inside the lower rod body 1, with one end of each screw 7... Each part is fixedly equipped with a knob 8. The upper rod 2 has two threaded grooves 9 inside, and each threaded groove 9 matches the other end of the screw 7. Through the electroplated layer 4, multiple strip-shaped limiting plates 3 and the screw 7, the multiple strip-shaped limiting plates 3 can slide up and down inside the corresponding strip-shaped limiting groove, thereby improving the stability of the upper rod 2 when pulling up and down, and preventing the bottom end of the upper rod 2 from colliding and rubbing against the inner wall of the lower rod 1. Turning the knob 8 causes one end of the screw 7 to be threaded into the threaded groove 9, thereby locking the upper rod 2 and preventing the upper rod 2 from shaking during use, which would affect the normal use of the umbrella.
[0028] In order to prevent screw 7 from falling off, such as Figure 1-4 As shown, an annular limiting plate 10 is fixedly sleeved on the wall of the screw 7. The annular limiting plate 10 is disposed on one side of the inner wall of the lower rod body 1. The annular limiting plate 10 can prevent the screw 7 from falling off.
[0029] In order to reduce the production cost and weight of the multiple strip-shaped limiting plates 3, and to ensure that the multiple strip-shaped limiting plates 3 have high corrosion resistance and oxidation resistance, such as Figure 1-3 As shown, each strip limiting plate 3 is a hollow plate and each strip limiting plate 3 is a stainless steel plate. By setting multiple strip limiting plates 3 to stainless steel, the stainless steel material has high corrosion resistance and oxidation resistance, which can reduce the production cost and weight of multiple strip limiting plates 3, and also ensure that multiple strip limiting plates 3 have high corrosion resistance and oxidation resistance.
[0030] To ensure that the lower rod 1 and the upper rod 2 have high corrosion resistance and oxidation resistance, such as Figure 1-4 As shown, both the lower rod 1 and the upper rod 2 are stainless steel rods. The lower rod 1 and the upper rod 2 are made of stainless steel. Stainless steel has high corrosion resistance and oxidation resistance, thus ensuring that the lower rod 1 and the upper rod 2 have high corrosion resistance and oxidation resistance.
[0031] In order to increase the friction between the user's hand and the grip handle 11, and to improve the stability of the user holding the umbrella, such as Figure 1-4As shown, a gripping rod 11 is fixedly installed at the bottom of the lower rod 1. The gripping rod 11 has multiple anti-slip threads 12 on its wall. The gripping rod 11 and multiple anti-slip threads 12 can increase the friction between the user's hand and the gripping rod 11 and improve the stability of the user holding the umbrella.
[0032] Finally, in order to reduce the friction between the multiple strip-shaped limiting plates 3 and the corresponding strip-shaped limiting grooves, not only was the noise generated when the strip-shaped limiting plates 3 moved up and down reduced, but the frictional resistance during up and down pulling was also reduced, such as... Figure 1-3 As shown, one side of each strip limiting plate 3 is arc-shaped. Setting one side of multiple strip limiting plates 3 to arc-shaped can reduce the friction between multiple strip limiting plates 3 and the corresponding strip limiting groove, which not only reduces the noise generated when the strip limiting plates 3 move up and down.
[0033] The above description illustrates only certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
