Technical Field

[0001] This utility model relates to the field of umbrella rod technology, specifically to an umbrella rod joint connection structure that prevents it from falling off. Background Technology

[0002] The umbrella shaft, also known as the umbrella ribs, is the core supporting component of an umbrella. It supports the entire umbrella frame structure and is usually made of materials such as iron, aluminum, wood, or fiberglass. Its material directly affects the umbrella's stability and wind resistance. As the "backbone" of the umbrella, the shaft connects the handle and the ribs and bears all the force when the umbrella is open. Its structure needs to be both lightweight and high-strength, and modern manufacturing often uses a segmented design to achieve portability.

[0003] Existing patent CN206822169U discloses an umbrella center rod comprising an outer tube and an inner tube. The inner tube is placed inside the outer tube and can slide up and down relative to the outer tube. The outer tube has a scratch-resistant bushing at the end extending from the inner tube, which prevents the outer surface of the inner tube from contacting the inner surface of the end of the outer tube. This invention's umbrella center rod can avoid scratches caused by frequent up-and-down sliding, and is particularly suitable for umbrella center rods with various colored paint finishes or films on their outer surface.

[0004] While current umbrella sticks are retractable, the connection between them and the handle is relatively cumbersome, as is replacing them. Furthermore, the handle can easily detach from the stick after prolonged use, reducing its practicality. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing an anti-detachment umbrella stem joint connection structure. This solves the problems mentioned in the background art, such as the fact that although the existing umbrella stem can be extended and retracted, the connection between the umbrella stem and the umbrella handle is relatively cumbersome, the replacement between the umbrella handle and the umbrella stem is relatively cumbersome, and the umbrella handle is prone to detaching from the umbrella stem after long-term use, thus reducing its practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a joint connection structure for preventing umbrella rods from falling off, comprising a main tube, a branch tube inside the main tube, an umbrella handle at the bottom of the main tube, a fixing component between the main tube and the umbrella handle, and a positioning component between the main tube and the branch tube;

[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. 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: an anti-fall-off umbrella handle joint connection structure, including a main pipe 1, a branch pipe 11 inside the main pipe 1, an umbrella handle 12 at the bottom of the main pipe 1, a fixing component between the main pipe 1 and the umbrella handle 12, and a positioning component between the main pipe 1 and the branch pipe 11. The fixing component includes a movable cavity 21 opened on one side of the top of the umbrella handle 12, a through-hole 22 opened on the top of the movable cavity 21, a movable plate 23 connected to the movable cavity 21, a push plate 24 fixedly connected to the top of the movable plate 23, a groove 25 opened on one side of the movable cavity 21, a guide rod 26 fixedly connected to one side of the movable plate 23, a first spring 27 sleeved on the outside of the guide rod 26, a fixing rod 28 fixedly connected to the other side of the movable plate 23, and a fixing hole 29 opened on one side of the main pipe 1. The fixing rod 28 is inserted into the fixing hole 29, the push plate 24 is slidably connected to the through-hole 22, the movable plate 23 is slidably connected to the movable cavity 21, the umbrella handle 12 is screwed to the main pipe 1, and the guide rod 26 is fixedly connected to the groove. 25. A sliding connection is made. The two ends of the first spring 27 are fixedly connected to the moving plate 23 and the movable cavity 21, respectively. Pushing the push plate 24 to move can drive the moving plate 23 to move. The movement of the moving plate 23 can drive the fixed rod 28 to move. At the same time, it can drive the first spring 27 to deform. The umbrella handle 12 can be screwed to the bottom of the main pipe 1. The reset of the first spring 27 can drive the fixed rod 28 to reset, so that it can be locked into the fixed hole 29. This can improve the connection stability between the umbrella handle 12 and the main pipe 1 and facilitate the replacement of the umbrella handle 12. A protective cover 61 is screwed to the outside of the umbrella handle 12. The main pipe 1 is slidably connected to the protective cover 61. The protective cover 61 can be screwed to the top of the umbrella handle 12 to cover the push plate 24 and protect it. A support rod 71 is fixedly connected to the inner wall of the through 22. The support rod 71 passes through the push plate 24 and is slidably connected to the push plate 24. The push plate 24 can slide on the outside of the support rod 71. The support rod 71 can guide the push plate 24 and prevent the push plate 24 from tilting when it moves.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5The positioning components include a groove 31 on one side of the branch pipe 11, a slide rod 32 connected to the groove 31, a hemisphere 33 fixedly connected to one end of the slide rod 32, a second spring 34 fixedly connected to the other end of the slide rod 32, and multiple hemisphere grooves 35 evenly arranged on one side of the main pipe 1. The slide rod 32 is slidably connected to the groove 31. The two ends of the second spring 34 are fixedly connected to the inner walls of the slide rod 32 and the groove 31, respectively. When the branch pipe 11 moves, the hemisphere 33 can disengage from the current hemisphere groove 35, thereby causing the slide rod 32 to compress the second spring 34 and deform it. When the hemisphere 33 comes into contact with other hemisphere grooves 35, the second spring 34 returns to its original position, causing the hemisphere 33 to snap into the hemisphere groove 35. This can fix the moved branch pipe 11 and achieve multi-level adjustment. A sliding part 351 is provided, which is arc-shaped. The sliding part 351 facilitates the insertion or removal of the hemisphere 33 into or out of the hemisphere groove 35. An anti-detachment plate 41 is fixedly connected to the side of the main pipe 1 away from the hemisphere groove 35. An anti-detachment groove 42 is provided on the side of the branch pipe 11 away from the sliding groove 31. The anti-detachment plate 41 is slidably connected to the anti-detachment groove 42. The movement of the branch pipe 11 can make the anti-detachment plate 41 slide in the anti-detachment groove 42, which can prevent the branch pipe 11 from falling off the main pipe 1. Anti-rotation grooves 51 are respectively provided on both sides of the inner wall of the sliding groove 31. Anti-rotation plates 52 are fixedly connected to both sides of the sliding rod 32. The anti-rotation plates 52 are slidably connected to the anti-rotation grooves 51. The movement of the sliding rod 32 can drive the anti-rotation plates 52 to move. The anti-rotation plates 52 can prevent the sliding rod 32 from rotating, thereby preventing the second spring 34 from rotating and being damaged.

[0026] Working principle: During operation, first, the protective cover 61 is placed on the outside of the main pipe 1. Then, the push plate 24 is pushed. The movement of the push plate 24 causes the moving plate 23 to move, which in turn causes the first spring 27 to deform. Simultaneously, the moving plate 23 causes the fixing rod 28 to move. Then, the umbrella handle 12 is screwed to the bottom of the main pipe 1, achieving initial connection and fixation. Then, the push plate 24 is released. At this time, the first spring 27 returns to its original position, which in turn causes the moving plate 23 to return to its original position, which in turn causes the fixing rod 28 to return to its original position, allowing it to engage with the fixing hole 29. This ensures a stable connection and fixation between the umbrella handle 12 and the main pipe 1. Finally, the protective cover 61 is screwed to the top of the umbrella handle 12. When replacement is needed later, the protective cover 61 is first loosened. Move it upwards, then push the push plate 24 again to disengage the fixing rod 28 from the fixing hole 29. Then unscrew the umbrella handle 12. The movement of the branch pipe 11 can cause the hemisphere 33 to disengage from the current hemispherical groove 35. The movement of the hemisphere 33 can drive the slide rod 32 to move. The movement of the slide rod 32 can drive the second spring 34 to deform. When the hemisphere 33 contacts other hemispherical grooves 35, the second spring 34 resets and can drive the hemisphere 33 to reset, so that it is stuck in the hemispherical groove 35. This can fix the branch pipe 11 and prevent the branch pipe 11 from moving. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
