Description

Technical Field

[0001] The utility model relates to the technical field of flipping shafts, in particular to a positioning flipping shaft. Background Art

[0002] A shaft generally refers to a rotating shaft, which is usually used to drive mechanical equipment or connect workpieces. The shaft is usually made of metal materials and has certain strength and wear resistance to ensure that it will not break or be damaged when rotating or bearing heavy loads.

[0003] In the prior art, there is a patent document with the publication number CN217558930U. This patent document discloses a flipping positioning shaft structure, including a lower template. On the upper side of the lower template, bearing seats are symmetrically arranged on the left and right. Inside the upper side of the bearing seats, bearings are installed. Inside the bearings, a shaft is installed. On the upper side of the shaft, an upper cover is installed through a loading groove. By first fixing the upper cover to the shaft and realizing the rotation of the shaft through the bearings, the upper cover makes a flipping motion up and down, so that the upper cover opens and closes. The repeated positioning accuracy with the lower die is high. Through the adaptation setting of the two ends of the shaft and the inner cavity of the bearings, the connection between the shaft and the bearings is realized, so that the friction between the shaft and the bearings is small, and the flipping open cover structure is realized. The flipping open is smooth without resistance, the service life is increased, and the positioning is accurate, thus solving the problems of inaccurate rotation positioning of the shaft, unsmooth movement, large rotational friction, and short service life.

[0004] The above and the prior art have the following defects: During the use of the shaft, when the external driving force is lost, the upper cover is easily rotated by its own gravity and contacts the lower template. Therefore, it is difficult to keep the upper cover stationary after rotation as needed and maintain a certain angle with the lower template, thus limiting the use range of the shaft.

[0005] Therefore, a positioning flipping shaft is proposed. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the defect that it is difficult to keep the upper cover stationary after rotation as needed and maintain a certain angle with the lower template, and a positioning flipping shaft is proposed.

[0008] The effects achieved by the above components are as follows: By setting the positioning structure, during the process of flipping the second connecting plate, the position of the circular plate is fixed by using the frictional force, thereby restricting the position of the second connecting plate, so that the second connecting plate can stably maintain the included angle with the first connecting plate unchanged after rotation, expanding the application range of the rotating shaft body.

[0010] The effects achieved by the above components are as follows: The fixing tube with a vertical cross-section of a regular hexagon on its outer periphery can prevent the top frame from rotating along with the circular plate.

[0013] Preferably, a plurality of anti-slip grooves are formed on the arc surface of the circular frame.

[0014] The effects achieved by the above components are as follows: The anti-slip grooves serve to facilitate the rotation of the circular frame.

[0015] Preferably, a sealing ring is rotatably connected to the inner wall of the circular frame, and the sealing ring is slidably connected with the fixing tube.

[0018] The effects achieved by the above components are as follows: The rough pad serves to increase the frictional force between the circular plate and the top frame.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows

[0026] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0028] Such as Figures 1-4As shown in the figure, the utility model provides a positioning and flipping rotating shaft, which includes a first connecting plate 1. Two fixed seats 2 are fixedly connected to the surface of the first connecting plate 1. A bearing 3 is fixedly connected inside the fixed seat 2. A rotating shaft body 4 is fixedly connected to the inner wall of the bearing 3. A second connecting plate 5 is fixedly connected to the surface of the rotating shaft body 4. A positioning structure 6 is arranged on the surface of the first connecting plate 1. The positioning structure 6 includes two fixed tubes 61. The fixed tubes 61 are fixedly connected to the first connecting plate 1. A top frame 62 is slidably sleeved on the surface of the fixed tubes 61. A threaded block 63 is threadedly connected to the inner wall of the fixed tubes 61. One end of the threaded block 63 close to the top frame 62 is rotatably connected to a transition plate. A spring 64 is fixedly connected between the top frame 62 and the transition plate. The vertical cross-section of the outer circumference of the fixed tube 61 is regular hexagon. The fixed tube 61 with a vertical cross-section of regular hexagon on the outer circumference can prevent the top frame 62 from rotating with the circular plate 65. One end of the threaded block 63 is fixedly connected to a circular frame 66. When the circular frame 66 is rotated, the circular frame 66 will drive the threaded block 63 to rotate.

[0029] A plurality of anti-slip grooves 67 are formed on the arc surface of the circular frame 66, and the anti-slip grooves 67 serve to facilitate the rotation of the circular frame 66.

[0030] A sealing ring 68 is rotatably connected to the inner wall of the circular frame 66. The sealing ring 68 is slidably connected to the fixed tube 61. When the circular frame 66 moves, it will drive the sealing ring 68 to move along the surface of the fixed tube 61. The sealing ring 68 can prevent foreign objects from entering between the fixed tube 61 and the circular frame 66 and interfering with the normal rotation of the threaded block 63.

[0031] A rough pad 69 is fixedly connected to the surface of the top frame 62, and the rough pad 69 serves to increase the friction between the circular plate 65 and the top frame 62.

[0032] The overall working principle is as follows: during the process of flipping the second connecting plate 5, the rotation of the rotating shaft body 4 following the second connecting plate 5 will drive the circular plate 65 to rotate. The spring 64 will push the top frame 62 by virtue of its own elastic force. The top frame 62 will make the rough pad 69 contact with the circular plate 65. The rough pad 69 serves to increase the friction between the circular plate 65 and the top frame 62. At the same time, the spring 64 can increase the friction between the circular plate 65 and the rough pad 69 by using its own elastic force, thereby fixing the position of the circular plate 65 by means of friction, and further restricting the position of the second connecting plate 5, so that the second connecting plate 5 can stably maintain the included angle with the first connecting plate 1 unchanged after rotation. When it is necessary to adjust the elastic force of the spring 64, rotate the circular frame 66. The circular frame 66 will drive the threaded block 63 to rotate. At this time, the anti-slip groove 67 serves to facilitate the rotation of the circular frame 66. The threaded block 63 will drive the transition plate to move by means of the thread. When the threaded block 63 moves towards the direction close to the fixed seat 2, the spring 64 will be compressed. At this time, the pressure of the top frame 62 on the circular plate 65 will increase, thereby increasing the friction between the rough pad 69 and the circular plate 65. The movement of the circular frame 66 will drive the sealing ring 68 to move along the surface of the fixed pipe 61. The sealing ring 68 can prevent foreign objects from entering between the fixed pipe 61 and the circular frame 66 and interfering with the normal rotation of the threaded block 63. The fixed pipe 61 with a regular hexagon vertical cross-section on the outer periphery can prevent the top frame 62 from rotating following the circular plate 65.

[0033] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
