Description

Technical Field

[0001] The utility model belongs to the technical field of micro motors, in particular to a micro motor with a bearing capable of stably supporting the motor. Background Art

[0002] Micromotors are small in size and capacity, with output power generally below a few hundred watts. They are widely used in control systems or to transmit mechanical loads, performing functions such as detecting, analyzing, amplifying, executing, or converting electromechanical signals or energy. There are many different types and models of micromotors, and their compactness and flexibility have led to their widespread application in various fields.

[0003] The micromotor's shaft is fitted with bearings, which are typically directly sleeved onto the outside of the shaft, making them difficult to secure. The shaft rotates during use, and prolonged rotation can lead to the bearings becoming less stable and prone to loosening, impacting the shaft's stable operation. Furthermore, the micromotor requires a power cord connected to the pins during use. These cords are typically long, allowing the micromotor to be installed in various locations. Micromotors can be installed inside various instruments and equipment. If the instrument or equipment experiences a strong collision or falls, the power cords attached to the pins can become loose or experience poor contact, impacting the micromotor's operation. Summary of the Invention

[0004] The purpose of the present utility model is to provide a micro motor with a bearing that can stably support the motor, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a micro motor with a stable bearing support, comprising a motor housing, a cover body, a pin, a rotor, a rotating shaft and a bearing body, a cover body being installed on the outside of the motor housing, a pin being connected to the outside of the cover body, a rotor being installed inside the motor housing, an end of the rotor being connected to the rotating shaft, a bearing body being sleeved on the outside of the rotating shaft, a connecting rod being welded to the inside of the motor housing, an end of the connecting rod being connected to a cross plate, a slider being slidably connected to the outside of the connecting rod, a buffer spring being connected between the slider and the cross plate, an arc-shaped support block being connected to the outside of the slider near the bearing body, a threaded rod being threadedly connected to the inside of the motor housing, an end of the threaded rod away from the bearing body being connected to a rotating block, and a sealing gasket being connected to the side of the rotating block close to the motor housing.

[0006] Preferably, a plug hole is provided on a side of the arc-shaped support block away from the bearing body, and a plug-in structure is formed between the threaded rod and the arc-shaped support block.

[0007] Preferably, the arc-shaped support blocks are arranged in two groups symmetrically about the center of the bearing body.

[0008] Preferably, a connecting plate is connected to the outer side of the cover body, and a T-shaped rod is connected to the side of the connecting plate close to the pin.

[0009] Preferably, the end of the T-shaped rod is threadedly connected to a threaded column, and one end of the threaded column is connected to a rotating block.

[0010] Preferably, a side of the rotating block close to the T-bar is connected to a push rod, and an outer side of the T-bar is slidably connected to a pressure plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When the utility model is in use, the rotating block rotates, driving the threaded rod and the motor housing to slide threadedly, and the sealing gasket rotates with the rotating block. When the end of the threaded rod moves to the inside of the arc-shaped support block, the end of the threaded rod will push the arc-shaped support block toward the bearing body. When the slider slides, the buffer spring will be compressed. When the arc surfaces of the ends of the two groups of arc-shaped support blocks move to the outer surface of the bearing body, the two groups of arc-shaped support blocks will clamp and fix the bearing body. The bearing body can be supported and fixed by the two groups of arc-shaped support blocks, thereby enhancing the stability of the bearing body installation, so that the bearing body can stably support the rotating shaft, to ensure that the rotating shaft can run stably for a long time.

[0013] When the power cord is connected to the pin, the excess part of the power cord is put on the T-bar in a circular manner. After the excess power cord is placed, the pressure plate is put on the T-bar, and then the end of the threaded column is inserted into the end of the T-bar, and the rotating block is rotated forward. When the rotating block rotates, it drives the push rod to rotate. When the push rod rotates, its end will squeeze and fix the pressure plate, so that the power cord on the T-bar is not easy to loosen, so that the connection position of the power cord and the pin is not easy to loosen or have poor contact, thereby enhancing the stability of the connection between the power cord and the pin.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 It can be seen that the present invention provides a technical solution: a micro motor with a stable bearing support, comprising a motor housing 1, a cover 2, a pin 3, a rotor 4, a rotating shaft 5 and a bearing body 6. The outer side of the motor housing 1 is installed with a cover 2, the outer side of the cover 2 is connected with a pin 3, the inside of the motor housing 1 is installed with a rotor 4, the end of the rotor 4 is connected with a rotating shaft 5, the outer side of the rotating shaft 5 is sleeved with a bearing body 6, a connecting rod 7 is welded to the inside of the motor housing 1, the end of the connecting rod 7 is connected with a cross plate 8, the outer side of the connecting rod 7 is slidably connected with a slider 9, and the slider A buffer spring 10 is connected between 9 and the cross plate 8, an arc-shaped support block 11 is connected to the outer side of the slider 9 near the bearing body 6, a threaded rod 12 is connected to the internal thread of the motor housing 1, and a rotating block 13 is connected to the end of the threaded rod 12 away from the bearing body 6. A sealing gasket 14 is connected to the side of the rotating block 13 close to the motor housing 1, and a socket is provided on the side of the arc-shaped support block 11 away from the bearing body 6. A plug-in structure is formed between the threaded rod 12 and the arc-shaped support block 11, and two groups of arc-shaped support blocks 11 are symmetrically arranged about the center of the bearing body 6.

[0023] During specific implementation, after the bearing body 6 is installed inside the motor housing 1, the two groups of rotating blocks 13 can be rotated forward respectively. When the rotating block 13 rotates, it drives the threaded rod 12 and the motor housing 1 to slide threadedly, and the sealing gasket 14 rotates with the rotating block 13. When the end of the threaded rod 12 moves to the inside of the arc support block 11, the end of the threaded rod 12 will push the arc support block 11 toward the direction of the bearing body 6. When the arc support block 11 moves, it drives the slider 9 to move. When the slider 9 moves, it slides through the connecting rod 7. When the slider 9 slides, it compresses the buffer spring 10. When the arc surfaces at the ends of the two groups of arc support blocks 11 move to the outer surface of the bearing body 6, the two groups of arc support blocks 11 will clamp and fix the bearing body 6, and at the same time, the sealing gasket 14 will be squeezed and fixed to the surface of the motor housing 1 by the rotating block 13.

[0024] See Figures 1-4 It can be seen that the bearing body 6 can be supported and fixed by two sets of arc-shaped support blocks 11, thereby enhancing the stability of the installation of the bearing body 6, so that the bearing body 6 can stably support the rotating shaft 5, ensuring that the rotating shaft 5 can operate stably for a long time.

[0025] See Figure 1 and Figure 5 It can be seen that the outer side of the cover body 2 is connected to a connecting plate 15, and the side of the connecting plate 15 close to the pin 3 is connected to a T-shaped rod 16, the end of the T-shaped rod 16 is threadedly connected to a threaded column 17, one end of the threaded column 17 is connected to a rotating block 18, and the side of the rotating block 18 close to the T-shaped rod 16 is connected to a push rod 19, and the outer side of the T-shaped rod 16 is slidably connected to a pressure plate 20, and the pressure plate 20 is made of stainless steel.

[0026] During specific implementation, after the power cord is connected to the pin 3, the excess part of the power cord is put on the T-shaped rod 16 in a circular manner. After the excess power cord is placed, the pressure plate 20 is put on the T-shaped rod 16, and the pressure plate 20 is pushed in the direction of the power cord so that the pressure plate 20 squeezes the power cord, and then the end of the threaded column 17 is inserted into the end of the T-shaped rod 16, and the rotating block 18 is rotated forward. When the rotating block 18 rotates, it drives the top rod 19 to rotate.

[0027] See Figure 1 and Figure 5 It can be seen that when the push rod 19 rotates, its end will squeeze and fix the pressure plate 20, so that the power cord on the T-bar 16 is not easy to loosen, and the connection position between the power cord and pin 3 is not easy to loosen or have poor contact, thereby enhancing the stability of the connection between the power cord and pin 3.

[0028] To sum up, when the present invention is used, the two groups of rotating blocks 13 are rotated forward respectively. When the rotating blocks 13 rotate, the threaded rod 12 and the motor housing 1 are driven to slide threadedly. The bearing body 6 can be supported and fixed by the two groups of arc-shaped support blocks 11, thereby enhancing the stability of the installation of the bearing body 6, so that the bearing body 6 can stably support the rotating shaft 5, ensuring that the rotating shaft 5 can run stably for a long time; when the top rod 19 rotates, its end will squeeze and fix the pressure plate 20, so that the power cord on the T-bar 16 is not easy to loosen, so that the connection position of the power cord and the pin 3 is not easy to loosen and have poor contact, thereby enhancing the stability of the connection between the power cord and the pin 3.
