Description

Technical Field

[0001] This utility model relates to the field of buzzer technology, specifically a snap-on buzzer that is easy to assemble and disassemble. Background Technology

[0002] A buzzer is an integrated electronic sounder, a type of electronic component, powered by either DC or AC voltage. Buzzers are widely used in the computer industry (primarily motherboard buzzers, chassis buzzers, and computer buzzers), printers (control board buzzers), copiers, alarm systems (alarm buzzers, siren buzzers), electronic toys (musical buzzers), agriculture, automotive electronics (vehicle buzzers, reversing buzzers, car buzzers, and motorcycle buzzers), telephones (environmental buzzers), timers, air conditioners, medical equipment, and other electroacoustic industries. Buzzers can also be used in environmental monitoring.

[0003] The patent document with announcement number CN220731168U describes a snap-fit ​​buzzer. A transition plate is pre-installed to the ceiling using screws. Then, a base with the buzzer is aligned with the transition plate. Simultaneously, both hands press down on the pressure plate, causing the bushing to rotate and the snap-fit ​​head to flip outwards, stretching the spring. The base and transition plate are then brought into contact, and their positions are adjusted so that the snap-fit ​​head aligns with the internal slot. The pressure plate is released, and the spring's reset effect causes the snap-fit ​​head to reposition and engage with the internal slot, thus securing the buzzer.

[0004] However, in the process of implementing the above technical solution, the following technical problems were found:

[0005] This snap-on buzzer uses a pressure plate to stretch the spring of the snap-on head, which then snaps into the internal slot after resetting, thus fixing the buzzer in place. However, in practical applications, using two snap-on heads results in poor stability when fixing the buzzer, while using multiple snap-on heads makes it difficult to disassemble the buzzer with one hand, which is quite troublesome. Utility Model Content

[0006] To overcome the shortcomings of existing snap-on buzzers, such as poor stability when using two clips to fix the buzzer in practical applications, and the difficulty of disassembling the buzzer with multiple clips by one hand, this application provides a snap-on buzzer that is easy to assemble and disassemble. The buzzer housing is secured to the outside of three spring pieces via three recessed slots. Rotating the buzzer housing causes one end of each of the three spring pieces to retract from the recessed slots and deform until one end of each spring piece is pushed into the three limiting slots. The bottom inner wall of the limiting slots blocks the spring pieces, preventing the buzzer housing from detaching from the buzzer base, thus achieving the effect of fixing the buzzer housing to the base. To remove the buzzer housing, simply continue rotating the buzzer housing until one end of the spring piece abuts against the inner wall of the buzzer housing; this method is simple and convenient.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A snap-on buzzer that is easy to assemble and disassemble includes a buzzer housing and a buzzer base, with the buzzer body located inside the buzzer housing.

[0009] The buzzer base is located at the bottom of the buzzer housing;

[0010] The top of the buzzer base is machined with a storage slot, the bottom of the buzzer base is machined with a movable slot, three spring pieces are provided on the inner wall of the bottom of the storage slot, and three recessed slots and three limiting slots are provided on the inner wall of the buzzer housing.

[0011] The three recessed slots, three limiting slots, and three spring pieces are evenly spaced around the center of the buzzer base. The buzzer housing is fastened to the outside of the three spring pieces through the three recessed slots, and after rotation, the three spring pieces are deformed, causing one end of each spring piece to be pushed into the interior of the three limiting slots.

[0012] In one possible implementation, two pins extend from the buzzer body away from the buzzer housing, and a movable slot is machined at the bottom of the buzzer base; the interior of the movable slot is connected to the interior of the storage slot, and the movable slot and the storage slot connect the top and bottom of the buzzer base, with the two pins passing through the interior of the storage slot and the movable slot.

[0013] In one possible implementation, one end of the spring sheet is bent into an arc-shaped piece in the direction away from the side wall of the limiting slot, and the connection point between the arc-shaped piece and the spring sheet is smoothly transitioned to the outside.

[0014] In one possible implementation, the end of the spring piece away from the side wall of the storage slot is integrally formed with a column, the bottom of the column is provided with a prism seat, and three prism slots are opened at the bottom inner wall of the storage slot.

[0015] In one possible implementation, the three prism seats are located inside the three prism slots respectively, and are threadedly connected to the buzzer base by bolts passing through the interior of the column and the prism seats, thereby fixing the spring to the inside of the receiving slot.

[0016] In one possible implementation, a gap is left between the end of the three spring pieces near the side wall of the receiving slot and the side wall of the receiving slot, and the thickness of the inner wall of the recessed slot away from the center of the buzzer base and the outer edge of the buzzer base is smaller than the gap.

[0017] In one possible implementation, the screw passes through the receiving slot into the buzzer base, so that the bolt head is received inside the buzzer base, thereby fixing the buzzer base to the target position.

[0018] The beneficial effects of this application are as follows:

[0019] Firstly, in this solution, the buzzer housing is secured to the outside of three spring pieces via three recessed slots. By rotating the buzzer housing, one end of each of the three spring pieces is dislodged from the three recessed slots and deformed until one end of each spring piece is pushed into the three limiting slots. The bottom inner wall of the limiting slots blocks the spring pieces, thus preventing the buzzer housing from detaching from the buzzer base. This achieves the effect of fixing the buzzer housing to the buzzer base. When it is necessary to remove the buzzer housing, simply continue to rotate the buzzer housing until one end of the spring piece abuts against the inner wall of the buzzer housing. It is simple and convenient.

[0020] Secondly, in this solution, by cooperating with the prism base and the prism slot, the column at one end of the spring is placed to the bottom inner wall of the storage slot. After the bolt passes through the inside of the column and the prism base and is threadedly connected to the buzzer base, the spring is fixed to the inside of the storage slot, which can improve the stability of the spring setting.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] Example 1:

[0028] This embodiment describes the specific structure of a snap-on buzzer that is easy to assemble and disassemble. See details below. Figures 1-4 As shown, it includes a buzzer housing 1 with a buzzer body 5 inside and a buzzer base 2 located at the bottom of the buzzer housing 1. The top of the buzzer base 2 is machined with a storage slot 12, and the bottom of the buzzer base 2 is machined with a movable slot 3. Three spring pieces 10 are provided on the bottom inner wall of the storage slot 12. The inner wall of the buzzer housing 1 is provided with three recessed slots 6 and three limiting slots 13.

[0029] like Figure 2 As shown, two pins 4 extend from the buzzer body 5 away from the buzzer housing 1, and a movable slot 3 is machined at the bottom of the buzzer base 2; the interior of the movable slot 3 is connected to the interior of the storage slot 12, and the movable slot 3 and the storage slot 12 connect the top and bottom of the buzzer base 2, and the two pins 4 pass through the interior of the storage slot 12 and the movable slot 3.

[0030] Specifically, by having three recessed slots 6, three limiting slots 13, and three spring pieces 10 evenly spaced around the center of the buzzer base 2, and leaving a gap between the end of the three spring pieces 10 near the side wall of the receiving slot 12 and the side wall of the receiving slot 12, and the thickness of the inner wall of the recessed slot 6 away from the center of the buzzer base 2 and the outer edge of the buzzer base 2 is less than this gap, when the buzzer housing 1 is fastened to the outside of the three spring pieces 10 by means of the three recessed slots 6, the gap between one end of the spring piece 10 and the side wall of the receiving slot 12 can be used to avoid the three spring pieces 10 from blocking the buzzer housing 1.

[0031] Meanwhile, when the buzzer housing 1 is fastened to the outside of the three spring pieces 10 by means of the three recessed slots 6, the buzzer housing 1 can be rotated to make one end of the three spring pieces 10 respectively exit from the inside of the three recessed slots 6 and deform. When one end of the spring piece 10 slides along the inner wall of the buzzer housing 1 to the inside of the limiting slot 13, one end of the three spring pieces 10 can be pushed into the inside of the three limiting slots 13 respectively. With the blocking of one end of the spring piece 10 by the bottom inner wall of the limiting slot 13, the buzzer housing 1 is restricted from being disconnected from the buzzer base 2.

[0032] Secondly, to ensure that the spring piece 10 slides smoothly from the recessed groove 6 into the limiting groove 13, such as... Figure 3 and Figure 4 As shown, one end of the spring piece 10 is bent into an arc-shaped piece 11 away from the side wall of the limiting slot 13. By making the outer side of the connection point between the arc-shaped piece 11 and the spring piece 10 smoothly transition, during the rotation of the buzzer housing 1, the spring piece 10 and the arc-shaped piece 11 can be supported to slide smoothly from the inner wall of the recessed slot 6 to the inner wall of the buzzer housing 1. During this process, they gradually deform. After the deformed end of the spring piece 10 reaches the position of the limiting slot 13, it resets.

[0033] The above design allows the buzzer housing 1 to be fastened to the outside of the three spring pieces 10 by means of the three recessed slots 6. The gap between one end of the spring piece 10 and the side wall of the receiving slot 12 is used to prevent the three spring pieces 10 from blocking the buzzer housing 1. After the buzzer housing 1 is rotated inside the receiving slot 12, one end of each of the three spring pieces 10 is deformed and withdrawn from the inside of the three recessed slots 6. When one end of the spring piece 10 slides along the inner wall of the buzzer housing 1 to the inside of the limiting slot 13, one end of each of the three spring pieces 10 can be pushed into the inside of the three limiting slots 13 by means of deformation. The bottom inner wall of the limiting slot 13 blocks one end of the spring piece 10, thus preventing the buzzer housing 1 from disengaging from the buzzer base 2, thereby achieving the effect of fixing the buzzer housing 1 to the buzzer base 2.

[0034] During disassembly, simply continue rotating to allow one end of the spring piece 10 to exit from inside the limiting slot 13 and reach the inner wall of the buzzer housing 1, and the buzzer housing 1 can be removed from inside the buzzer base 2 along the axial direction.

[0035] Example 2:

[0036] Based on Example 1, this example describes the specific structure of the buzzer base 2. The end of the spring piece 10 away from the side wall of the storage slot 12 is integrally formed with a column 8. A prism seat 9 is provided at the bottom of the column 8. Three prism slots 7 are opened at the bottom inner wall of the storage slot 12.

[0037] In this method, by passing the screw through the receiving slot 12 through the buzzer base 2 and storing the bolt head inside the buzzer base 2, the buzzer base 2 is fixed to the target position. After fixing the buzzer housing 1 to the buzzer base 2, the buzzer housing 1 can be fixed to the target position.

[0038] Secondly, by placing the three prism seats 9 inside the three prism slots 7 respectively, and by threading bolts through the inside of the column 8 and the prism seats 9 to the buzzer base 2, the spring piece 10 is fixed to the inside of the receiving slot 12. With the cooperation of the prism seats 9 and the prism slots 7, the spring piece 10 is prevented from rotating around the bolt inside the column 8 due to the pressure exerted by the rotating buzzer housing 1, thereby improving the stability of the spring piece 10.

[0039] In the process of fixing the spring piece 10 to the bottom inner wall of the storage slot 12, the column 8 at one end of the spring piece 10 is arranged to the bottom inner wall of the storage slot 12 through the cooperation of the prism seat 9 and the prism slot 7. After the bolt passes through the inside of the column 8 and the prism seat 9 and is threadedly connected to the buzzer base 2, the spring piece 10 is fixed to the inside of the storage slot 12. This can prevent the spring piece 10 from being rotated around the bolt inside the column 8 due to the pressure applied by the rotating buzzer housing 1, thereby improving the stability of the spring piece 10.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
