[0002] Balloons are mainly used for decoration, celebrations, and advertising in various occasions. Balloons come in various colors, shapes, and sizes, and can be used individually or combined into various shapes, so a balloon knotter is needed.

[0003] Balloon knotters are made of plastic and are small and portable. They typically have a specific slot to hold the neck of the balloon in place, allowing for easy knotting. However, balloon knotters are prone to damage with frequent use. The clips or slots inside the knotter wear and deform after repeatedly clamping the balloon's mouthpiece and knotting. Current solutions involve designing the clip's connecting part to be wider and thicker to enhance its resistance to deformation under stress. For the slot, the wall thickness is increased to improve its overall compressive strength. However, while this increases structural strength, it also affects the flexibility of the balloon knotter, requiring greater operating force. This is inconvenient for users, especially during prolonged use, and can easily lead to hand fatigue. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a balloon knotter, which aims to improve the flexibility of the balloon knotter. It requires greater operating force, which is not convenient for users, especially during long-term use, and can easily lead to hand fatigue.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a balloon knotter, comprising an outer shell, a partition fixedly connected to the left end of the inner wall of the outer shell, a spring fixedly connected to the right side of the outer wall of the partition, a movable cylinder fixedly connected to the right end of the spring, a connecting post fixedly connected to the middle of the left end of the movable cylinder, the left end of the connecting post penetrating the partition and fixedly connected to a metal opening and closing end, a movable groove provided in the middle of the top end of the outer shell, a pushing post provided at the top of the movable cylinder, the pushing post being slidably connected to the movable groove, and a disassembly mechanism provided at the right end of the outer shell for disassembly.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 4 and Figure 5An embodiment of this utility model provides a balloon knotter, including an outer shell cylinder 1. A partition 8 is fixedly connected to the left end of the inner wall of the outer shell cylinder 1. A spring 3 is fixedly connected to the right side of the outer wall of the partition 8. A movable cylinder 5 is fixedly connected to the right end of the spring 3. A connecting post 4 is fixedly connected to the middle of the left end of the movable cylinder 5. The left end of the connecting post 4 passes through the partition 8 and is fixedly connected to a metal opening and closing end 6. A movable groove 20 is opened in the middle of the top end of the outer shell cylinder 1. A pushing post 7 is provided at the top of the movable cylinder 5. The pushing post 7 is slidably connected to the movable groove 20. A disassembly mechanism 2 is provided at the right end of the outer shell cylinder 1. The disassembly mechanism 2 is used for disassembly.

[0032] Specifically, a partition 8 is firmly fixed to the left end of the inner wall of the outer shell 1, which plays an important role in separation. A spring 3 is fixedly connected to the right side of the outer wall of the partition 8. The spring 3 has good elasticity, deforms when subjected to force, and returns to its original shape after the external force is removed. The right end of the spring 3 is connected to the movable cylinder 5, which can move left and right under the elastic action of the spring 3. A connecting post 4 is fixedly connected to the middle of the left end of the movable cylinder 5. The connecting post 4 passes through the partition 8 and is fixedly connected to the metal opening and closing end 6. When the connecting post 4 moves, it can drive the metal opening and closing end 6 to perform corresponding actions. A moving groove 20 is opened in the middle of the top of the outer shell 1. A pushing post 7 is set on the top of the movable cylinder 5. The pushing post 7 is slidably connected to the moving groove 20. When the staff applies external force to the pushing post 7, the pushing post 7 can slide along the moving groove 20, thereby driving the movable cylinder 5 to move and realize the knotting operation of the balloon.

[0033] Reference Figure 2 , Figure 3 and Figure 5 The disassembly mechanism 2 includes a rear cover 201. The left end of the rear cover 201 is located at the right end of the inner wall of the outer shell cylinder 1. A threaded groove 202 is provided at the left end of the inner wall of the outer shell cylinder 1. The threaded groove 202 is threadedly connected to the rear cover 201. A fixing plate 203 is provided at the top of the movable cylinder 5. The top of the fixing plate 203 is fixedly connected to the push column 7. Screws 204 are threadedly connected to the left and right sides of the top of the fixing plate 203. The bottom of the two screws 204 is threadedly connected to the top of the movable cylinder 5.

[0034] Specifically, when the spring 3 inside the balloon knotter weakens due to prolonged use and needs to be replaced, the device housing is opened by rotating the rear cover 201 and unscrewing it from the threaded groove 202 of the outer casing cylinder 1. At the same time, when further disassembly of the internal structure is required, the screw 204 connecting the top fixing plate 203 of the moving cylinder 5 to the push column 7 and the moving cylinder 5 is unscrewed to disconnect the fixing plate 203, so that the spring 3 can be replaced and the balloon knotter can be restored to normal performance.

[0035] Reference Figure 1 , Figure 3 and Figure 5A protective pad 9 is fixedly connected to the outer wall of the push column 7, and an anti-slip groove 21 is provided on the outer wall of the protective pad 9; two mounting holes 10 are provided on the right side of the outer wall of the rear cover 201, and a hanging ring 11 is fixedly connected to the inner wall of each of the two mounting holes 10; a second mounting groove 12 is provided on the top front side of the outer shell cylinder 1, and an indicator arrow 13 is fixedly connected to the inner wall of the second mounting groove 12.

[0036] Specifically, a protective pad 9 is fixedly connected to the outer wall of the push column 7, and an anti-slip groove 21 is provided on its outer wall to effectively increase friction, making it easier and safer for operators to operate the push column 7. Two mounting holes 10 are provided on the right side of the outer wall of the rear cover 201, and hanging rings 11 are fixedly connected to the inner walls of the two mounting holes 10. The hanging rings 11 provide convenience for storing the balloon knotter and make it easy to hang it. A second mounting groove 12 is provided on the top front side of the outer shell cylinder 1, and an indicator arrow 13 is fixedly connected to the inner wall of the second mounting groove 12 to provide a clear direction for operation.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the back cover 201 has mounting grooves 14 on both the front and rear sides, and the inner walls of the two mounting grooves 14 are fixedly connected with rotating arrows 15; the outer wall of the outer shell cylinder 1 has a connecting groove 16 on the right end, and the inner wall of the connecting groove 16 is fixedly connected with an anti-slip pad 17; the outer wall of the outer shell cylinder 1 has a connecting groove 18 on the left end, and the inner wall of the connecting groove 18 is fixedly connected with a limit groove 19.

[0038] Specifically, the rotating arrow 15 in the mounting groove 14 on the front and rear sides of the outer wall of the back cover 201 provides intuitive directional guidance for the installation and removal of the back cover 201. The anti-slip pad 17 in the connecting groove 16 on the right end of the outer wall of the outer shell 1 increases friction and prevents loosening when connected to the back cover 201. The limiting groove 19 in the connecting groove 18 on the left end of the outer wall of the outer shell 1 prevents the balloon from sliding when it is wrapped around the left end of the outer shell 1, ensuring the stability of the balloon position.

[0039] Working principle: First, an inflated balloon is wrapped around the limiting groove 19. The operator manually pushes the pusher 7 to the left. The pusher 7 slides to the left in the moving groove 20 at the top center of the outer shell cylinder 1, which in turn pushes the moving cylinder 5 to the left. The moving cylinder 5 drives the metal opening and closing end 6 to the left through the connecting column 4. At this time, the spring 3 is compressed, and the balloon mouth is hooked by the hook of the metal opening and closing end 6, so that it enters the device. Then, the balloon is allowed to slide down to the outside crossing position. The pusher 7 is released. Under the elastic restoring force of the spring 3, the spring 3 pushes the moving cylinder 5 to the right. The moving cylinder 5 drives the metal opening and closing end 6 to the right through the connecting column 4, thus completing the knotting operation of the balloon.

[0040] Furthermore, when the spring 3 inside the balloon knotter becomes less elastic due to prolonged use, it needs to be replaced. This is done by rotating the back cover 201 to unscrew it from the threaded groove 202 of the outer casing 1, opening the outer casing. At the same time, the fixing plate 203 at the top of the moving cylinder 5 is fixedly connected to the push column 7 and to the moving cylinder 5 via screws 204. When further disassembly of the internal structure is required, the two screws 204 are unscrewed to disconnect the fixing plate 203 from the push column 7 and the moving cylinder 5, facilitating the replacement of the spring 3 inside the balloon knotter, thereby ensuring that the balloon knotter can be restored to normal operating performance.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
