Description

Technical Field

[0001] The utility model relates to the technical field of bouncing cores, and more specifically, to a bouncing core. Background Art

[0002] At present, bouncing cores are widely used in various fields, such as mostly used in drain stoppers, and are mainly used for pressing and opening the pressing cover of the drain stopper. The structure of the existing bouncing cores on the market is mainly the same as the patent with the publication number CN113047384A. In order to ensure the stability of use, a screw hole is provided on the bouncing outer shell, a bolt is screwed in the screw hole, and the end of the bolt is positioned in the chute. Through the positioning of the bolt, the bouncing inner core can only move vertically up and down and cannot rotate horizontally.

[0003] However, the existing technology also has certain defects: during the long-term use of the bouncing core, since the bouncing inner core and the bouncing outer shell need to slide relative to each other each time of use, the bolt will be subject to the friction and vibration of the bouncing inner core, which is likely to cause the bolt to move outwards, and then it is easy for the bolt to fall off the bouncing outer shell; moreover, due to the relatively thin thickness of the bouncing outer shell, there are few thread teeth in its screw hole. After the bolt moves outwards, the gap between the bolt and the bouncing inner core becomes too large, which will cause the screw hole to be rubbed larger and larger, and finally the bolt will be stripped of its threads, and finally the user will not be able to use it. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bouncing core, which can propose a solution for the deficiencies of the existing technology. It replaces the original bolt with a limiting rod. During the use process, the limiting rod will not move outwards and fall off, and the structure is stable, avoiding the risk of the bolt of the traditional bouncing core being stripped of its threads.

[0031] Embodiment

[0032] Please refer to Figures 1 - 7 , this embodiment provides a bouncing core, including a bouncing outer shell 1, a bouncing inner core 2 and a U-shaped bouncing hook 4. The bottom of the bouncing inner core 2 is slidably arranged in the bouncing outer shell 1. A reset spring 3 is arranged in the bouncing outer shell 1. One end of the reset spring 3 abuts against the bottom of the bouncing inner core 2, and the other end of the reset spring 3 abuts against the bouncing outer shell 1. The bouncing inner core 2 is provided with a heart-shaped bouncing guide groove 5. A positioning convex column 6 is arranged at the bottom of the bouncing outer shell 1. One end of the bouncing hook 4 is embedded in the heart-shaped bouncing guide groove 5, and the other end of the bouncing hook 4 is connected to the positioning convex column 6. The bouncing inner core 2 is provided with a guiding sliding groove 7, and further includes a limiting rod 8. The bouncing outer shell 1 is provided with a mounting hole 9. One end of the limiting rod 8 passes through the mounting hole 9 and is embedded in the guiding sliding groove 7. A protective sleeve 10 is sleeved on the outer side wall of the bouncing outer shell 1. An installation plate 11 is arranged between the other end of the limiting rod 8 and the inner side wall of the protective sleeve 10. The other end of the limiting rod 8 is fixed to the installation plate 11, and the installation plate 11 abuts against the inner side wall of the protective sleeve 10.

[0033] In actual use, the pressing cover of the drainer can be installed on the top of the bouncing inner core 2, and the sealing main body of the drainer can be installed on the bouncing outer shell 1. Threads can be provided on the outer side wall of the bouncing outer shell 1 and the outer side wall of the bouncing inner core 2 respectively, and they can be installed by means of threaded connection. When the bouncing core works, when pressing down the pressing cover of the drainer, at this time the bouncing inner core 2 moves downward, and at the same time the top end of the bouncing hook 4 moves upward at the bottom of the heart-shaped bouncing guide groove 5. When reaching a certain distance, the bouncing hook 4 will be clamped at the concave part at the top end of the heart-shaped bouncing guide groove 5.

[0034] When pressing down again, the top end of the bouncing hook 4 slides out from the concave part at the top end of the heart-shaped bouncing guide groove 5, and then release the pressing cover. Under the action of the return spring 3, the bouncing inner core 2 slides upward, and at the same time the bouncing hook 4 moves downward along the track of the heart-shaped bouncing guide groove 5. When reaching the concave part at the bottom end of the heart-shaped bouncing guide groove 5, it is clamped, and at this time the bouncing inner core 2 no longer slides, and the bouncing inner core 2 and the bouncing outer shell 1 remain relatively stationary. By setting the limiting rod 8, when the bouncing inner core 2 slides up and down, the limiting rod 8 slides in the guiding chute 7, which improves the sliding stability of the bouncing inner core 2. Moreover, by setting the protective sleeve 10, the other end of the limiting rod 8 is fixed to the mounting plate 11, and the mounting plate 11 abuts against the inner side wall of the protective sleeve 10. In this way, through the socket fixing of the protective sleeve 10, the mounting plate 11 and the limiting rod 8 will not slide outward during use. Therefore, compared with the prior art, in this application, the original bolt is replaced with the limiting rod 8, and the limiting rod 8 will not move outward and fall during use, the structure is stable, and the risk of the bolt of the traditional bouncing core slipping threads is avoided.

[0035] As Figures 1 - 7 shown, in some embodiments of the present utility model, the bouncing outer shell 1 is provided with a receiving groove 12 communicating with the mounting hole 9, and the mounting plate 11 is embedded in the receiving groove 12. By setting the receiving groove 12 in the present utility model, it is convenient to accommodate and install the mounting plate 11 through the receiving groove 12, and further convenient for the protective sleeve 10 to be sleeved on the bouncing outer shell 1 for installation.

[0036] As Figures 1 - 7 shown, in some embodiments of the present utility model, the cross-section of the limiting rod 8 along its radial direction is polygonal. In this embodiment, the limiting rod 8 is in the shape of a cuboid, and the corresponding mounting hole 9 is also in the shape of a cuboid. In this way, the limiting rod 8 will not rotate relative to the bouncing outer shell 1, further improving the installation stability of the limiting rod 8.

[0037] As Figures 1 - 7 shown, in some embodiments of the present utility model, the protective sleeve 10 is connected with the bouncing outer shell 1 by interference fit. By setting the protective sleeve 10 to be connected with the bouncing outer shell 1 by interference fit in the present utility model, it is convenient to fix the protective sleeve 10 on the outer side wall of the bouncing outer shell 1.

[0038] As Figures 1 - 7As shown, in some embodiments of the present utility model, a tapered surface 13 is provided on the inner side wall at one end of the protective sleeve 10. The diameter of the outer end of the tapered surface 13 is larger than that of the inner end. In this way, when installing the protective sleeve 10, it is convenient for the bouncing outer shell 1 to be inserted into the protective sleeve 10 for interference fit installation.

[0039] As Figures 1 - 7 shown, in some embodiments of the present utility model, a limiting ring 14 is fixedly provided on the outer side wall of the bouncing outer shell 1, and the protective sleeve 10 abuts against the limiting ring 14. By providing the limiting ring 14 in the present utility model, it is convenient to determine the installation position of the protective sleeve 10.

[0040] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of this application, this application can be implemented in other specific forms.
