[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] In order to address the technical problem in the prior art where the vibrating component is fixed in the housing by fasteners, and the fasteners may loosen after long-term operation of the vibrating component, thus affecting the stability of the vibrating component, this utility model provides a vibration mechanism that can provide installation stability for the vibrating component.

[0025] Please see Figures 1-3 , Figures 1-3 A vibration mechanism according to one embodiment of the present invention includes a housing 1, a clamping part 2, and a vibrating element 3. The clamping part 2 includes two buffer rings 21, which are spaced apart inside the housing 1. The vibrating element 3 is disposed inside the housing 1, and the opposite ends of the two vibrating elements 3 are respectively inserted into the two buffer rings 21. The vibrating element 3 can drive the housing 1 to vibrate.

[0026] In actual use, the outer shell 1 is connected to the object that needs to be vibrated, and the vibrator 3 is turned on. The vibrator 3 generates a vibration force, which drives the outer shell 1 to vibrate. The outer shell 1 can then transmit the vibration force to the object, keeping the object vibrating. The two buffer rings 21 fix the vibrator 3 inside the outer shell 1, which can effectively improve the installation stability of the vibrator 3 and prevent the vibrator 3 from becoming loose during vibration.

[0027] In one embodiment, the outer casing 1 is cylindrical and includes a first housing 11, a second housing 12, and a locking member. The first housing 11 and the second housing 12 are connected and enclosed by the locking member to form the outer casing 1, wherein the locking member is a plurality of screws.

[0028] In one embodiment, the vibrating element 3 is a vibration motor. In other embodiments, a vibrator can be used instead of a vibration motor. The vibration motor combines a motor and an eccentric block into one. The rotating magnetic field generated by the motor itself drives the rotor to rotate, which in turn drives the eccentric block to generate centrifugal force, causing the mechanism to vibrate. The vibration frequency and amplitude can be adjusted by adjusting the power supply frequency, voltage, or changing the angle of the eccentric block.

[0029] It should be noted that when the vibrating element 3 is a dual-output shaft vibrating motor, the axes of the two output shafts of the vibrating motor coincide with the central axis of the outer casing 1, and the vibrating element 3 is located in the middle of the outer casing 1.

[0030] Based on the above solution, in order to avoid relative rotation between the vibrating element 3 and the buffer ring 21, the clamping part 2 further includes two limiting covers 22. The two limiting covers 22 are respectively fixed at opposite ends of the vibrating element 3. The periphery of the limiting cover 22 is provided with at least one limiting protrusion 221. The buffer ring 21 is sleeved with the limiting cover 22, and the inner ring of the buffer ring 21 is provided with a limiting groove 211 that cooperates with the limiting protrusion 221.

[0031] Furthermore, in order to prevent the vibrating element 3 from sliding along the central axis of the outer shell 1 during operation, specifically, one end of each of the two limiting covers 22 is provided with a stop 222, and the two stop blocks 222 respectively abut against the side of the two buffer rings 21 that are close to each other.

[0032] In addition, to prevent the buffer ring 21 from rotating inside the outer shell 1, specifically, the outer ring of the buffer ring 21 is provided with at least one slot 212, and the inner wall of the outer shell 1 is provided with a locking block that cooperates with the slot 212.

[0033] In one embodiment, the outer shell 1 is provided with two annular grooves 1a spaced apart, and the two buffer rings 21 are respectively engaged in the two annular grooves 1a; it should be noted that the first shell 11 and the second shell 12 are each provided with two semi-circular arc grooves spaced apart, and the annular grooves 1a are formed by the enclosing of the corresponding two semi-circular arc grooves of the first shell 11 and the second shell 12.

[0034] In one embodiment, the side wall of the first housing 11 is provided with at least one first protrusion 111, and the first protrusion 111 is provided with a first through hole. The side wall of the second housing 12 is provided with at least one second protrusion 121, and the second protrusion 121 is provided with a second through hole. An installation gap is formed between the first protrusion 111 and the second protrusion 121, and the central axis of the first through hole and the second through hole coincides.

[0035] In order to prevent the heat generated by the vibrating component from accumulating inside the housing, the outer shell 1 is provided with multiple heat dissipation holes at one end or at both opposite ends. In this specific embodiment, the outer shell 1 is provided with multiple heat dissipation holes at both opposite ends.

[0036] It should be noted that the buffer ring 21 is made of elastic rubber material. There are multiple recesses between the inner and outer rings of the buffer ring 21, and the inner ring of the buffer ring 21 is slightly smaller than the outer diameter of the vibrating element, so that the buffer ring 21 can be tightly clamped to the end of the vibrating element.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below:

[0038] When using a vibration mechanism, one side of the transmission plate can be inserted into the installation gap. After bolts are passed through the first through hole, the connecting hole on the transmission plate, and the second through hole in sequence, they are screwed into the nut to fix the transmission plate to the housing. When the vibrating component is running, it drives the housing to vibrate, thereby causing the transmission plate to vibrate.

[0039] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
