Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to an anti-reverse motor. Background Technology
[0002] Motors convert electrical energy into mechanical energy to drive machinery to perform rotation, vibration, or linear motion, and are widely used in the fields of automatic control and mechatronics.
[0003] However, existing motors are usually mounted on the device by a fixed bracket and then fixed to the device with bolts to provide power. However, the device will generate a certain amount of vibration during operation. The vibration of the device will cause the bolts to vibrate along with it, which will cause the bolts to rotate and loosen, thus causing the motor to lose its stability. When the motor loses its stability, the connection between the motor output end and the device is easily damaged, which will lead to damage to the motor. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:
[0005] An anti-reverse motor includes a motor body, a fixed base is installed at the lower end of the motor body, the inner cavity of the fixed base is threadedly connected to the outer wall of a bolt, and the bolt has a groove, and an anti-reverse mechanism is installed in the inner cavity of the fixed base.
[0006] The anti-reverse mechanism includes a gear, a slide groove, a gear plate, a fixed plate, and a first fixed rod. The lower end of the gear is rotatably connected to the inner cavity of the fixed seat. The slide groove is opened at both ends of the inner cavity of the fixed seat. The outer wall of the gear plate is engaged with the inner cavity of the slide groove, and the ends of the gear plates that are close to each other are meshed with the outer wall of the gear. One end of the fixed plate is fixedly connected to both ends of the gear plate. One end of the first fixed rod is fixedly connected to one end of the fixed plate, and the ends of the first fixed rod that are far apart from each other are sleeved with a hole opened in the inner cavity of the fixed seat.
[0007] As an improvement to the above technical solution, the anti-reverse mechanism includes a rotating shaft, the outer wall of which is rotatably connected to the upper end of the fixed base, and the lower end of the rotating shaft is fixedly connected to the upper end of the gear. A handle is installed on the upper end of the rotating shaft.
[0008] As an improvement to the above technical solution, a soft pad is installed on the lower end face of the fixing seat, and the soft pad has holes for the avoidance bolts.
[0009] As an improvement to the above technical solution, a spring is installed at one end of the fixed seat and one end of the spring is fixedly connected to one end of the second fixed rod. The ends of the second fixed rod that are close to each other pass through the inner cavity of the spring and the fixed seat and are engaged with the inner cavity of the gear plate.
[0010] As an improvement to the above technical solution, one end of the second fixing rod is rectangular and is engaged with the inner wall of one end of the fixing seat, and a pull ring is installed at the opposite end of the second fixing rod to facilitate pulling by personnel.
[0011] As an improvement to the above technical solution, the inner cavity of the slide is equipped with a rotating ball, and the upper end of the rotating ball overlaps with the outer wall of the gear plate.
[0012] The beneficial effects of this utility model are:
[0013] By rotating the gear, the gear plate that meshes with it is moved. The movement of the gear plate drives the fixed plate and the first fixed rod to move. At this time, the first fixed rod passes through the hole opened in the inner cavity of the fixed seat and engages with the groove opened on the outer wall of the bolt, preventing the bolt from reversing due to vibration. This ensures the bolt's fixing effect on the motor body, indirectly protecting the motor body, preventing the motor body from shaking, and avoiding damage to the motor body due to shaking.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0022] Please see Figure 1-6 This utility model provides a technical solution: an anti-reverse motor, including a motor body 1, a fixed seat 2 installed at the lower end of the motor body 1, the inner cavity of the fixed seat 2 being threadedly connected to the outer wall of a bolt 3, and the bolt 3 having a groove, and an anti-reverse mechanism 4 installed in the inner cavity of the fixed seat 2.
[0023] The anti-reverse mechanism 4 includes a gear 41, a slide groove 42, a gear plate 43, a fixing plate 44, and a first fixing rod 45. The lower end of the gear 41 is rotatably connected to the inner cavity of the fixing seat 2. The slide groove 42 is opened at both ends of the inner cavity of the fixing seat 2. The outer wall of the gear plate 43 is engaged with the inner cavity of the slide groove 42, and the ends of the gear plates 43 that are close to each other are meshed with the outer wall of the gear 41. One end of the fixing plate 44 is fixedly connected to both ends of the gear plate 43. One end of the first fixing rod 45 is fixedly connected to one end of the fixing plate 44, and the ends of the first fixing rod 45 that are far apart from each other are sleeved with the holes opened in the inner cavity of the fixing seat 2.
[0024] Rotating gear 41 moves gear plate 43, which meshes with it. The movement of gear plate 43 drives the movement of fixing plate 44. When fixing plate 44 moves, it drives the first fixing rod 45 to move. At this time, the first fixing rod 45 passes through the hole in the inner cavity of fixing seat 2 and engages with the groove in the outer wall of bolt 3, thereby preventing bolt 3 from reversing due to vibration. This ensures the fixing effect of bolt 3 on motor body 1, indirectly protecting motor body 1, preventing motor body 1 from shaking, and avoiding damage to motor body 1 due to shaking.
[0025] Specifically, the anti-reverse mechanism 4 includes a rotating shaft 46, the outer wall of which is rotatably connected to the upper end of the fixed base 2, and the lower end of the rotating shaft 46 is fixedly connected to the upper end of the gear 41. A handle is installed on the upper end of the rotating shaft 46.
[0026] By having a person hold the handle, the rotating shaft 46 can be easily rotated, which in turn drives the gear 41 to rotate. The rotation of the gear 41 causes the gear plate 43, the fixing plate 44, and the first fixing rod 45 to fix the bolt 3, thereby ensuring the fixing effect of the bolt 3 on the motor body 1 and thus ensuring the stability of the motor body 1 during operation.
[0027] Specifically, a soft pad is installed on the lower end face of the fixing base 2, and the soft pad has a hole for the clearance bolt 3.
[0028] The soft pad allows the fixed seat 2 to make full contact with the device, thereby ensuring the fixing effect of the bolt 3 on the fixed seat 2. At the same time, the soft pad can absorb some of the vibration generated by the device during operation, further ensuring the stability of the motor body 1 during operation.
[0029] Specifically, a spring 5 is installed at one end of the fixed base 2, and one end of the spring 5 is fixedly connected to one end of the second fixed rod 6. The ends of the second fixed rod 6 that are close to each other pass through the inner cavity of the spring 5 and the fixed base 2, and are engaged with the inner cavity of the gear plate 43.
[0030] The tension of spring 5 allows the second fixing rod 6 to automatically fix the gear plate 43 under tension, preventing the gear plate 43 from moving after fixing the bolt 3 by driving the fixing plate 44 and the first fixing rod 45. This increases the fixation of the bolt 3, improves the fixing effect of the bolt 3, and indirectly protects the motor body 1.
[0031] Specifically, one end of the second fixing rod 6 is rectangular and is engaged with the inner wall of one end of the fixing seat 2, and the ends of the second fixing rod 6 that are far apart from each other are equipped with pull rings that are easy for people to pull.
[0032] The rectangle allows the second fixed rod 6 to be limited, thus ensuring its horizontal stability during movement. The pull ring makes it easy for personnel to grip and pull the second fixed rod 6.
[0033] Specifically, the inner cavity of the slide 42 is equipped with a ball bearing, and the upper end of the ball bearing overlaps with the outer wall of the gear plate 43.
[0034] The installed ball bearings can reduce the friction generated when the gear plate 43 moves, thereby making the gear plate 43 move more easily by relying on the rotation of the gear 41.
[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
