Description
Technical field:
[0001] The utility model belongs to the technical field of electronic component manufacturing, and specifically relates to a magnetically attracted silent bouncing core. Background technology:
[0002] The spring core used in current push-type drains mainly relies on springs to provide the force required for the spring. During the opening and closing process, the collision between parts will produce a loud noise, and the spring is prone to deformation due to long-term force, resulting in elastic failure and shortening the service life of the spring core. Therefore, a spring core that can be used for a long time and has a silent effect is urgently needed. Utility model content:
[0003] The technical problem to be solved by the utility model is to provide a magnetically attracted silent bouncing core.
[0004] The technical solution of the utility model is to provide a magnetic silent bouncing core, which is arranged in the drain hole of the bathroom drain device and drives the sealing cover to close or open the drain hole. The bouncing core is composed of a screw shaft, a cylindrical inner core, a turntable, a rotating shaft, a first magnet, a second magnet and an outer shell. The inner core is fixed in the outer shell, the turntable is accommodated in the inner core and can move downward along the axial direction of the inner core under the drive of the screw shaft, a guide block is provided on the outer circumferential surface of the turntable, and an oblique guide groove which is slidably matched with the guide block is provided on the lower part of the outer shell, the rotating shaft is plug-in matched with the screw shaft, and the rotating shaft is rotated. The table sleeve is arranged on the rotating shaft and is rotatably connected therewith. A guide block and a guide block limiting groove are also provided on the inner wall of the inner core. The guide block is located at the lower part of the inner core. The guide block limiting groove is arranged along the axial direction of the inner core. When the cover is closed, the guide block cooperates with the guide block limiting groove on the turntable. When the cover is opened, the guide block limiting groove limits the guide block so that the turntable moves up and down without rotating. The first magnet is fixedly installed in the rotating shaft, and the second magnet is fixedly installed at the bottom of the outer shell. The first magnet and the second magnet are arranged opposite to each other up and down, and the adjacent magnetic poles of the first magnet and the second magnet are the same.
[0005] The utility model is characterized in that the rotating shaft cooperates with the first magnet, the first magnet is fixedly installed in the rotating shaft, the second magnet cooperates with the shell, and the second magnet is fixedly installed in the shell; a guide block is provided on the outer circumferential surface of the turntable, which has a guiding function; the first magnet and the second magnet realize the effect of a spring through the principle of repulsion of the same level. In actual use, the turntable is driven to move downward by pressing the screw shaft, and when it reaches the bottom, the guide block of the turntable rotates under the guidance of the oblique guide groove of the shell. Since the turntable needs to be pressed to the bottom to contact the oblique guide groove of the shell to rotate, this process is active force rotation, and the entire rotation process is determined by the user's pressing process, rather than passive rotation due to the upward force itself. This process is the main process for the collision between parts to produce sound. Most of the sounds emitted by the bouncing cores are due to the fact that the sliding parts are changed by the force at the moment when the bouncing core changes its state, resulting in collision between parts to produce sound. This magnetic silent bouncing core changes the state from instantaneous to artificial control.
[0006] Preferably, the height difference of the spring core between the cover closed state and the cover open state is 13.6 mm.
[0007] Preferably, a slot is provided on the circumferential surface of the outer shell, a buckle matching the slot is provided on the outer circumferential surface of the inner core, and the inner core and the outer shell are connected and fixed by the buckle and the slot, which is convenient for installation and disassembly.
[0008] Preferably, a limiting block is further provided on the circumferential outer wall of the inner core, and correspondingly, a limiting groove cooperating with the limiting block is provided on the outer shell, which plays a role of fixed limiting.
[0009] Preferably, the top of the screw shaft has an external thread that is connected and matched with the sealing cover, so as to facilitate connection and fixation.
[0010] Preferably, a plurality of guide convex strips are evenly spaced along the axial direction on the outer peripheral surface of the screw shaft, and a corresponding positioning groove is provided in the inner cavity of the inner core, which plays a role in positioning and guiding.
[0011] Preferably, the guide block is triangular in shape, and the oblique guide groove is inclined from one end to the other end.
[0012] Preferably, the outer periphery of the first magnet and the second magnet is provided with an anti-oxidation epoxy resin layer to prevent the first magnet and the second magnet from rusting when immersed in water. The magnet can always be magnetically attracted under the environment that meets the conditions, and the magnetism will not disappear due to long-term force. The surface treatment of the magnet can prevent rust, thereby increasing the service life.
[0013] Preferably, the inner cavity at the lower end of the screw shaft has a limiting boss, and the screw shaft and the rotating shaft are limited by the limiting boss on the screw shaft.
[0014] Furthermore, the lower end of the screw shaft is plugged into the upper end of the rotating shaft to form an annular groove that cooperates with the rotation of the turntable. The size of the annular groove is about 0.2 mm larger than the thickness of the convex ring convexly arranged on the inner circumference of the turntable. This ensures that the turntable is not affected by the cooperation between other parts and can rotate easily.

[0027] In this embodiment, Figure 2 , 3As shown, the bouncing core is arranged in the drain hole of the bathroom drain device, and drives the sealing cover to close or open the drain hole. The bouncing core is composed of a screw shaft 1, an inner core 2, a turntable 3, a rotating shaft 4, a first magnet 5, a second magnet 6 and an outer shell 7. The inner core 2 is fixed in the outer shell 7, the turntable 3 is accommodated in the inner core 2 and can move downward along the axial direction of the inner core 2 under the drive of the screw shaft 1. A guide block 31 is provided on the outer circumferential surface of the turntable 3, which has a guiding function; the lower part of the outer shell 7 has an oblique guide groove 71 that is slidably matched with the guide block 31, the rotating shaft 4 is plug-fitted with the screw shaft 1, the turntable 3 is sleeved on the rotating shaft 4 and is rotatably connected thereto, and the inner core The inner wall of the inner core 2 is also provided with a guide block 21 and a guide block limiting groove 22. The guide block 21 is located at the lower part of the inner core. The guide block limiting groove 22 is arranged along the axial direction of the inner core 2. When the cover is closed, the guide block 21 is limited and matched with the guide block 31. For this purpose, one end of the guide block 21 has a limiting protrusion. When the cover is opened, the guide block limiting groove 22 limits the guide block 31 so that the turntable 3 moves up and down without rotating. The first magnet 5 is fixedly installed in the rotating shaft 4, and the second magnet 6 is fixedly installed at the bottom of the outer shell 7. The first magnet 5 and the second magnet 6 are arranged opposite to each other up and down, and the adjacent magnetic poles of the first magnet 5 and the second magnet 6 are the same.
[0028] like Figure 7 , 8 As shown, a slot 72 is also provided on the circumferential surface of the outer shell 7, and a buckle 23 is provided on the outer circumferential surface of the inner core 2 to match the slot 72. The inner core 2 and the outer shell 7 are connected and fixed by the buckle 23 and the slot 72, which is convenient for installation and disassembly. In addition, a limit block 24 is also provided on the circumferential outer wall of the inner core 2, and correspondingly, a limit groove 73 is provided on the outer shell 7 to match the limit block 24, which plays a role of fixed limit.
[0029] like Figure 4 , 5 As shown, the top of the screw shaft 1 has an external thread that is connected to the cover, which is convenient for connecting with the cover. The outer peripheral surface of the screw shaft 1 is evenly spaced along the axial direction with a number of guide ridges 11, and the inner cavity of the inner core 2 is provided with corresponding positioning grooves 25, which can play a positioning and guiding effect.
[0030] In addition, the lower end of the screw shaft 1 is plugged into the upper end of the rotating shaft 4 to form an annular groove 40 that cooperates with the rotation of the turntable. The size of the annular groove 40 is larger than the thickness of the convex ring 32 convexly provided on the inner circumference of the turntable 3 by 0.2 mm, ensuring that the turntable 3 is not affected by the cooperation between other parts and can rotate easily.
[0031] In addition, in this embodiment, the inner cavity at the lower end of the screw shaft 1 has a limiting boss 12. The screw shaft and the rotating shaft are limited by the boss on the screw shaft. The screw shaft 1 and the rotating shaft 4 can be limited by the limiting boss 12 on the screw shaft 1.
[0032] like Figure 6 As shown, the guide block 31 is triangular in shape, and the inclined guide groove 71 is inclined from one end to the other end.
[0033] Furthermore, in order to increase the service life, an anti-oxidation epoxy resin layer is provided on the outer periphery of the first magnet 5 and the second magnet 6 to prevent the first magnet 5 and the second magnet 6 from rusting when immersed in water.
[0034] The first magnet 5 and the second magnet 6 of the utility model realize the effect of the spring through the principle of repulsion of the same level. In actual use, the turntable 3 is driven to move downward by pressing the screw shaft 1. When it reaches the bottom, the guide block 31 of the turntable 3 rotates under the guidance of the oblique guide groove 71 of the shell 7. Since the turntable 3 must be pressed to the bottom to contact the oblique guide groove 71 of the shell 7 before it can rotate, this process is active force rotation. The entire rotation process is determined by the user's pressing process, rather than passive rotation due to the upward force itself. This process is the main process of collision between parts to make sounds. Most of the bouncing cores make sounds because the sliding parts are changed by the force at the moment when the bouncing core changes state, resulting in collisions between parts to produce sounds. This magnetic absorption silent bouncing core changes the state from instantaneous to a process of human control. There will be no instantaneous changes or collisions between parts, so a silent effect can be achieved. In addition, the magnet can achieve magnetic attraction under conditions that meet the conditions, and the magnetism will not disappear due to long-term force, thereby improving the service life.
