Description

Technical Field

[0001] The utility model relates to the technical field of eccentric wheels, in particular to an eccentric wheel structure. Background Art

[0002] An eccentric wheel, as the name implies, is a wheel whose center is not at the point of rotation. It generally refers to a circular wheel. When the circle does not rotate around its own center, it becomes an eccentric wheel. An eccentric wheel is also a type of cam. Generally speaking, the main purpose of an eccentric wheel is to generate vibration. Electric sieves and vibrators in mobile phones all use eccentric wheels. Most eccentric wheels are circular wheels because they are easy to manufacture and have simple processes. However, in actual life, we have found that when an existing eccentric wheel is in use, it may cause the device installed at the output end of the eccentric wheel to fall off due to long-term rotation, resulting in the need to adjust the position of the eccentric wheel again. For this reason, we propose an eccentric wheel structure. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] See also Figure 1-7 The utility model provides a technical solution: an eccentric wheel structure, including an eccentric wheel body 1, and also includes

[0029] The arc plate 2 is used to control the expansion in the eccentric body 1. Three arc plates 2 are provided, and the three arc plates 2 are all provided outside the eccentric body 1.

[0030] The rubber plate 3 is used to control the fixation of the eccentric body 1. Three rubber plates 3 are provided, and the three rubber plates 3 are all provided at the bottom of the eccentric body 1.

[0031] An expansion assembly 4, used for controlling the expansion of the three arc-shaped plates 2, and the expansion assembly 4 is arranged in the eccentric wheel body 1;

[0032] The rotating assembly 5 is used to control the rotation of the three rubber plates 3 to drive the three rubber plates 3 to clamp inwardly. The rotating assembly 5 is arranged at the bottom of the eccentric wheel body 1.

[0033] The expansion assembly includes a driving member 6 arranged in the eccentric wheel body 1 for providing power for the expansion of the three arc-shaped plates 2 , and a sliding member 7 for controlling the movement of the three arc-shaped plates 2 is arranged in the eccentric wheel body 1 .

[0034] The driving member 6 includes a driving rod 61 arranged in the eccentric wheel body 1, a thread 62 is provided on the outer side of the driving rod 61, and a driving handle 63 is provided on the top of the driving rod 61. The driving rod 61 is connected to the thread 62 of the eccentric wheel body 1 through the thread 62. When the user rotates the driving handle 63, the driving handle 63 will drive the driving rod 61 arranged at the bottom thereof to rotate, so that the driving rod 61 rotates in the eccentric wheel body 1 through the thread 62 and the driving rod 61 is raised. The function of the thread 62 is to make the driving rod 61 have self-locking ability through the thread 62.

[0035] The sliding member 7 includes sliding rods 71 ​​respectively arranged on the opposite sides of the three arc-shaped plates 2, and the bottom of the driving rod 61 is respectively provided with sliding grooves 72 used in conjunction with the three sliding rods 71, and the opposite ends of the three sliding rods 71 ​​are slidably arranged in the corresponding sliding grooves 72, and the outer sides of the three sliding rods 71 ​​are respectively provided with reset plates 73, and the opposite sides of the three reset plates 73 are respectively provided with reset springs 74. When the driving rod 61 is raised, the sliding groove 72 opened on the outer side of the driving rod 61 will rise together with the driving rod 61, because the sliding groove 72 is The cam 72 is in the form of a ramp. When the sliding groove 72 is raised, the sliding groove 72 will lift the sliding rod 71 sliding inside it while rising, so that the sliding rod 71 is spread away from the arc plate 2 at one end of the driving rod 61. The return spring 74 arranged on the outside of the sliding rod 71 will control the end of the sliding rod 71 close to the sliding groove 72 to always fit the sliding groove 72 through the return plate 73, so as to prevent the sliding rod 71 from separating from the eccentric wheel body 1. The function of the sliding groove 72 is to lift the sliding rod 71 when rotating, thereby lifting the arc plate 2 at the other end.

[0036] The rotating assembly 5 includes a fixing member 8 disposed at the bottom of the eccentric body 1 for controlling the stability of the eccentric body 1 .

[0037] The fixing member 8 includes three rotating plates 81 which are rotatably arranged at the bottom of the eccentric wheel through a rotating shaft, and three rubber plates 3 are respectively arranged at opposite ends of the three rotating plates 81. The three rotating plates 81 are all provided with fixing grooves 82. The bottoms of the three rotating plates 81 are all provided with fixing rods 83 which are used in conjunction with the three fixing grooves 82. The bottom of the eccentric wheel body 1 is provided with locking grooves 84 which are used in conjunction with the three fixing rods 83. When the fixing rods 83 are rotated, the fixing rods 83 control the rotating plates 81 to rotate in the eccentric wheel body 1, so that the rotating plates 81 are away from the fixing rods 83. The rubber plates 3 at the ends move together with the rotating plate 81, so that the three rubber plates 3 are clamped to the opposite sides to prevent the devices on the opposite sides of the three rubber plates 3 from slipping off. When the three rubber plates 3 reach the appropriate position, the fixing rod 83 is controlled to slide in the fixing groove 82, so that the fixing rod 83 is stuck in the locking groove 84 provided in the eccentric wheel body 1 to ensure that the rotating plate 81 will not slip off. The function of the fixing groove 82 is to enable the user to adjust the position of the fixing rod 83 sliding in the fixing groove 82 according to the rotation angle when the user controls the fixing rod 83 to rotate.

[0038] When in use, when the user rotates the driving handle 63, the driving handle 63 will drive the driving rod 61 arranged at the bottom thereof to rotate, so that the driving rod 61 is rotated in the eccentric wheel body 1 through the thread 62, and the driving rod 61 is raised. When the driving rod 61 is raised, the sliding groove 72 provided on the outside of the driving rod 61 will rise together with the driving rod 61. Since the sliding groove 72 is sloped, when the sliding groove 72 is raised, the sliding groove 72 will lift the sliding rod 71 sliding inside it while rising, so that the sliding rod 71 is spread away from the arc plate 2 at one end of the driving rod 61, and the return spring 74 arranged on the outside of the sliding rod 71 will control the return plate 73 to return to the original position. The end of the sliding rod 71 close to the sliding groove 72 is always in contact with the sliding groove 72 to prevent the sliding rod 71 from separating from the eccentric wheel body 1. When the fixing rod 83 is rotated, the fixing rod 83 controls the rotating plate 81 to rotate in the eccentric wheel body 1, so that the rubber plate 3 at one end of the rotating plate 81 away from the fixing rod 83 moves with the rotating plate 81, and then the three rubber plates 3 are clamped to the opposite sides to prevent the devices on the opposite sides of the three rubber plates 3 from slipping off. When the three rubber plates 3 reach the appropriate position, the fixing rod 83 is controlled to slide in the fixing groove 82 so that the fixing rod 83 is stuck in the locking groove 84 opened in the eccentric wheel body 1 to ensure that the rotating plate 81 will not slip off.

[0040] See also Figure 8 , the utility model provides a technical solution:

[0041] Different from Example 1, anti-skid grooves 9 are provided on the outer sides of the three arc-shaped plates 2. The anti-skid grooves 9 can increase the friction between the arc-shaped plates 2 and external instruments. Their function is to increase the friction force and ensure that the instruments on the outer sides of the arc-shaped plates 2 are difficult to slip off.
