Description

Technical Field

[0001] The utility model relates to the technical field of sprockets, in particular to a metal motor sprocket. Background Art

[0002] A motor sprocket (also known as a sprocket, chain wheel, or sprocket) is a key component in a motor-driven mechanical transmission system. It is primarily used to transmit the motor's rotational motion to other mechanical devices or components via a chain. It is typically mounted on the motor's output shaft and, in conjunction with the chain, forms a complete transmission system. When the motor sprocket and chain are used together, the motor rotates the sprocket to drive the chain, which in turn transmits power to other components via the sprocket at the other end.

[0003] Ordinary sprockets are fixed, so one type of sprocket can only be used in one environment, so the scope of application is small. Generally, multiple specifications of sprockets need to be configured, so the use is not flexible enough. Utility Model Content

[0004] The utility model aims to provide a metal motor sprocket, which solves the problem that the application range is small and sprockets of multiple specifications generally need to be configured, so the use is not flexible enough.

[0005] The utility model solves the above technical problems through the following technical solutions, and the utility model includes:

[0006] An external sprocket, wherein a plurality of teeth are evenly arranged on the edge of the external sprocket, and a built-in groove is opened on one side of the external sprocket;

[0007] A built-in sprocket is clamped in the built-in groove, and a plurality of connecting teeth are evenly arranged on the edge of the built-in sprocket. A through hole is opened between the center position of the built-in groove and the outer wall on the other side of the external sprocket. A coupling tube is installed on the rear side of the built-in sprocket, and the coupling tube is clamped in the through hole. A limiting ring is installed on the coupling tube.

[0008] Preferably, protruding blocks are welded on both sides of the limiting ring.

[0009] Preferably, a first positioning hole is formed on the protruding block, and a first positioning screw is fixed in the first positioning hole.

[0010] Preferably, two first positioning screw holes corresponding to the first positioning holes are provided on the rear side of the external sprocket, and one end of the first positioning screw is engaged and installed in the first positioning screw hole.

[0011] Preferably, a second positioning hole is formed on the protruding block, and a second positioning screw is fixed in the second positioning hole.

[0012] Preferably, two second positioning screw holes corresponding to the second positioning holes are provided on the rear side of the external sprocket, and one end of the second positioning screw is engaged and installed in the second positioning screw hole.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model can switch between the external sprocket and the internal sprocket according to needs. When the external sprocket is needed, the internal sprocket is placed in the internal groove, and the internal sprocket will not affect the normal use of the external sprocket. When the internal sprocket is needed, the internal sprocket can be pulled out of the internal groove and the internal sprocket can be used. At the same time, the side wall of the external sprocket on one side can limit the chain connected to the internal sprocket, thereby improving stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0022] This embodiment provides a technical solution: a metal motor sprocket, such as Figure 1-Figure 4 As shown, it includes an external sprocket 1 and an internal sprocket 4.

[0023] In the specific implementation, such as Figure 1 and Figure 3As shown, a plurality of teeth 2 are evenly arranged on the edge of the external sprocket 1, a built-in groove 3 is opened on one side of the external sprocket 1, and the built-in sprocket 4 is clamped in the built-in groove 3. A plurality of connecting teeth 5 are evenly arranged on the edge of the built-in sprocket 4, and a through hole 6 is opened between the center position of the built-in groove 3 and the outer wall of the other side of the external sprocket 1. A coupling tube 7 is installed on the rear side of the built-in sprocket 4, and the coupling tube 7 is clamped in the through hole 6. The external sprocket 1 and the built-in sprocket 4 can be switched and used as needed. When the external sprocket 1 needs to be used, the built-in sprocket 4 is placed in the built-in groove 3. At this time, Figure 1 As shown, the internal sprocket 4 does not affect the normal use of the external sprocket 1. When the internal sprocket 4 is needed, the coupling tube 7 is moved outward, and the internal sprocket 4 can be moved out of the internal groove 3. Figure 3 As shown, the built-in sprocket 4 can be used, and at the same time, the side wall of the external sprocket 1 on one side can limit the chain connected to the built-in sprocket 4, thereby improving stability. A limiting ring 8 is installed on the coupling tube 7, and the limiting ring 8 can prevent the coupling tube 7 from falling off.

[0024] Furthermore, protruding blocks 9 are welded on both sides of the limiting ring 8, and the protruding blocks 9 can further enhance the anti-falling effect.

[0025] Furthermore, a first positioning hole 10 is formed on the raised block 9 , and a first positioning screw 11 is fixed in the first positioning hole 10 . The first positioning screw 11 can be used to conveniently fix the coupling tube 7 when the external sprocket 1 is used.

[0026] Furthermore, two first positioning screw holes 12 corresponding to the first positioning hole 10 are opened on the rear side of the external sprocket 1, and one end of the first positioning screw 11 is engaged and installed in the first positioning screw hole 12. The first positioning screw 11 cooperates with the first positioning screw hole 12 to further improve the fixing effect.

[0027] Furthermore, a second positioning hole 13 is formed on the raised block 9 , and a second positioning screw 14 is fixed in the second positioning hole 13 . The second positioning screw 14 can be used to conveniently fix the coupling tube 7 when the built-in sprocket 4 is used.

[0028] Preferably, two second positioning screw holes 15 corresponding to the second positioning holes 13 are opened on the rear side of the external sprocket 1, and one end of the second positioning screw 14 is engaged and installed in the second positioning screw hole 15. The second positioning screw 14 cooperates with the second positioning screw hole 15 to further improve the fixing effect.

[0029] When the utility model is in use, the external sprocket 1 and the internal sprocket 4 can be switched as needed. When the external sprocket 1 is used, the internal sprocket 4 is placed in the internal groove 3 when the external sprocket 1 is needed. Figure 1As shown, the internal sprocket 4 does not affect the normal use of the external sprocket 1. The first positioning screw 11 is connected to the first positioning screw hole 12. At this time, the external sprocket 1 can be used. When the internal sprocket 4 needs to be used, the first positioning screw 11 is loosened first, and then the coupling tube 7 is moved outward. The internal sprocket 4 can be moved out of the internal groove 3. Figure 3 As shown, the built-in sprocket 4 can be used, and then the second positioning screw 14 is tightened to fix the built-in sprocket 4. At the same time, when the built-in sprocket 4 is used, the side wall of the external sprocket 1 on one side can limit the chain connected to the built-in sprocket 4, thereby improving stability.

[0030] The above are only preferred embodiments of the present invention and are intended to be illustrative rather than restrictive. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the embodiments within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
