Description

Technical Field

[0001] The utility model relates to the technical field of rotating shafts, in particular to a rotating shaft with stable connection. Background Art

[0002] A shaft is an axial component used to support and rotate parts or devices. It is usually used in mechanical equipment and industrial machinery to realize the rotational movement of parts or devices. The shaft is usually made of metal material with high strength and wear resistance to ensure that it can withstand certain loads and friction during rotation.

[0003] The existing related technologies often have the following defects: the rotating shaft is usually fixedly connected to the output end of the motor, and the traditional splicing method of the rotating shaft is often connected with the help of bolts. However, the screw rods are corroded during use, which easily reduces the splicing effect between the rotating shaft and the output shaft.

[0004] Therefore, the utility model provides a rotating shaft with stable connection. Utility Model Content

[0005] The utility model aims to solve the shortcoming in the prior art that it is inconvenient to quickly splice the rotating shaft and the output shaft, and proposes a rotating shaft with stable connection.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rotating shaft with stable connection, including an output shaft and a connecting shaft, the surface of the output shaft is fixedly connected with an insert block, the end side of the connecting shaft is provided with a socket, the size of the insert block is matched with the size of the socket, the side wall of the output shaft is provided with a card slot, the interior of the connecting shaft is slidably connected with two sliding pins, and the ends of the two sliding pins away from each other are fixedly connected with a card strip.

[0007] The effect achieved by the above components is: after the clamping strip is moved to a position corresponding to the clamping slot, the clamping strip is released to achieve a fixed and quick locking operation between the output shaft and the connecting shaft.

[0008] Preferably, the insert is a regular hexagonal prism structure.

[0009] The effect achieved by the above components is that the plug-in block with a regular hexagonal prism structure avoids the phenomenon of mutual twisting between the output shaft and the connecting shaft after docking.

[0010] Preferably, a spring is sleeved on the surface of the sliding pin, and two ends of the spring are fixedly connected to the connecting shaft and the clamping strip respectively.

[0011] The effect achieved by the above components is that the card strip is inserted into the inner side of the card slot under the pulling force of the spring on the connecting shaft.

[0012] Preferably, a positioning head is fixedly connected to the end side of the insert block, and the positioning head is a stepped structure.

[0013] The effect achieved by the above components is that the positioning head with a terrace-like structure improves the efficiency of inserting the insertion rod into the inner side of the insertion hole.

[0014] Preferably, a limit ring is sleeved on the outer side of the output shaft.

[0015] The effect achieved by the above components is: the limit ring is sleeved on the outside of the two clamping strips, which can prevent the clamping strips from being affected by centrifugal force and moving away from the output shaft during high-speed operation of the output shaft and the connecting shaft, resulting in the risk of falling off between the output shaft and the connecting shaft.

[0016] Preferably, a circular ring is fixedly connected to the surface of the output shaft, and a folding tube is fixedly connected between the circular ring and the limiting ring.

[0026] Reference Figure 1-5 As shown, the utility model provides a technical solution: a rotating shaft with a stable connection, including an output shaft 1 and a connecting shaft 2.

[0027] The following is a detailed description of its overall specific settings and functions.

[0028] In this embodiment: the surface of the output shaft 1 is fixedly connected with an insert block 11, the end side of the connecting shaft 2 is provided with an insert hole 5, the size of the insert block 11 matches the size of the insert hole 5, the side wall of the output shaft 1 is provided with a card slot 10, the interior of the connecting shaft 2 is slidably connected with two sliding pins 6, and the ends of the two sliding pins 6 that are away from each other are fixedly connected with a card strip 4. After the card strip 4 is moved to a position corresponding to the card slot 10, the card strip 4 is released, and the fixed quick lock between the output shaft 1 and the connecting shaft 2 can be realized.

[0029] The plug block 11 is a regular hexagonal prism structure. The plug block 11 with a regular hexagonal prism structure avoids the phenomenon of mutual twisting between the output shaft 1 and the connecting shaft 2 after docking. The surface of the sliding pin 6 is covered with a spring 7, and the two ends of the spring 7 are fixedly connected to the connecting shaft 2 and the clamping strip 4 respectively. The clamping strip 4 will be inserted into the inner side of the clamping groove 10 under the pulling force of the spring 7 on the connecting shaft 2. A positioning head 12 is fixedly connected to the end side of the plug block 11, and the positioning head 12 is a step-shaped structure. The positioning head 12 with a step-shaped structure improves the efficiency of inserting the plug rod into the inner side of the socket 5.

[0030] Specifically, the outer side of the output shaft 1 is covered with a limit ring 8. The limit ring 8 is covered on the outer side of the two clamping strips 4, which can prevent the clamping strip 4 from being affected by the centrifugal force and moving away from the output shaft 1 during the high-speed operation of the output shaft 1 and the connecting shaft 2, resulting in the risk of falling off between the output shaft 1 and the connecting shaft 2. A circular ring 9 is fixedly connected to the surface of the output shaft 1, and a folding tube 3 is fixedly connected between the circular ring 9 and the limit ring 8. The limit ring 8 is covered on the outer side of the two clamping strips 4 by the elastic force of the folding tube 3.

[0031] Working principle: when it is necessary to splice the output shaft 1 and the connecting shaft 2, pull the two clamping strips 4 to the side away from the connecting shaft 2, wherein the sliding pin 6 slides inside the connecting shaft 2 to limit the moving direction of the clamping strip 4, and insert the plug block 11 into the inner side of the socket 5, wherein the positioning head 12 with a stepped structure improves the efficiency of inserting the plug rod into the inner side of the socket 5, and now the output shaft 1 and the connecting shaft 2 can be quickly positioned. At this time, the limiting ring 8 can be slid toward the side close to the circular ring 9, and after moving the clamping strip 4 to the position corresponding to the slot 10, release the clamping strip 4. At this time, the clamping strip 4 will be inserted into the inner side of the slot 10 under the pulling force of the spring 7 on the connecting shaft 2, and the output shaft 1 and the connecting shaft 2 can be fixed and quickly locked. At this time, release the limiting ring 8. The ring 8 will be sleeved on the outside of the two clamping strips 4 under the elastic force of the folding tube 3, which can prevent the clamping strip 4 from being affected by the centrifugal force and moving away from the output shaft 1 during the high-speed operation of the output shaft 1 and the connecting shaft 2, resulting in the risk of the output shaft 1 and the connecting shaft 2 falling off, further improving the stability of the assembly between the output shaft 1 and the connecting shaft 2. By setting the above structure, the rapid positioning and assembly work between the output shaft 1 and the connecting shaft 2 is facilitated, and the limit ring 8 is set to improve the stability of the output shaft 1 and the connecting shaft 2 after being locked, reduce the risk of falling off between the output shaft 1 and the connecting shaft 2, change the traditional installation method between the output shaft 1 and the connecting shaft 2, and improve the assembly efficiency between the output shaft 1 and the connecting shaft 2 to a certain extent.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
