Description

Technical Field

[0001] This utility model relates to the technical field of limiting mechanisms, and in particular to a limiting mechanism for rotating machinery. Background Technology

[0002] A spray painting machine is a specialized coating equipment that uses spraying technology. Its principle is to control the airflow to instantly reverse the air distribution device, thereby causing the piston of the pneumatic motor to perform a stable and continuous reciprocating motion. The inhaled paint is pressurized and delivered to the spray gun of the spray painting machine through a high-pressure hose. The spray gun then instantly atomizes the paint and releases it onto the surface of the object being coated.

[0003] When using a sprayer or other related equipment, a limiting mechanism is needed to limit the rotation angle of the pipeline, thereby preventing the pipeline rotation angle from exceeding the standard range, such as the working range of 0 degrees to 440 degrees. If the rotation angle exceeds 440 degrees, it will exceed the standard range and cause the entire pipeline to be twisted off, affecting the normal use of the device. In related technologies, sensors and related control programs are set to limit the rotation angle to prevent the pipeline from being twisted off. However, in actual use, if the sensor and related control program malfunction and fail to limit the rotation properly, the pipeline may still be twisted off, which has certain limitations and is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a rotary mechanical limiting mechanism to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A rotary mechanical limiting mechanism includes: a connecting plate with cover plates on both sides;

[0007] A through hole is formed in the cover plate and the connecting plate; a first sliding groove is formed in the inner side of the connecting plate; an outer limiting ring is rotatably connected in the first sliding groove; a second sliding groove is formed in the inner side of the outer limiting ring; and an inner limiting ring is rotatably connected in the second sliding groove.

[0008] Optionally, the first groove includes: a first groove formed on the inner side of the connecting plate; and a second groove formed on the inner side of the connecting plate, wherein the first groove and the second groove communicate with each other.

[0009] Optionally, the first groove and the second groove are concentric circular grooves, and the curvature of the second groove is degrees, while the curvature of the first groove is degrees.

[0010] Optionally, a protrusion is fixedly connected to the outer side of the second groove, and the protrusion is inserted into the first groove.

[0011] Optionally, a protrusion three is fixedly connected to the outer side of the inner limiting ring, and the protrusion three is inserted into the sliding groove two.

[0012] Optionally, a second protrusion is fixedly connected to the inner side of the second groove, and the second protrusion is in close contact with the third protrusion.

[0013] Optionally, the inner limiting ring has a hole.

[0014] Optionally, the first bump, the second bump, and the third bump are all arc-shaped blocks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this application, the inner limiting ring rotates first. After the inner limiting ring rotates 330 degrees within the outer limiting ring, it drives the outer limiting ring to rotate within the slide groove. After rotating another 200 degrees, the outer limiting ring comes into contact with the slide groove, thereby limiting the inner and outer limiting rings and preventing excessive rotation angles that could cause the pipeline to break. This protects the pipeline and wiring and solves the problem that existing spraying machine limiting mechanisms do not have good limiting functions. Attached Figure Description

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Given that the existing technology uses sensors and related control programs to limit the rotation angle and prevent the pipeline from being twisted, in actual use, if the sensors and related control programs malfunction and fail to limit the rotation angle properly, the pipeline can still be twisted, which has certain limitations and is inconvenient to use.

[0033] like Figure 1-6 As shown, this utility model embodiment provides a rotary mechanical limiting mechanism, including: a connecting plate 12 with cover plates 10 on both sides; a through hole 11 formed on the cover plate 10 and the connecting plate 12; a first sliding groove 20 formed on the inner side of the connecting plate 12; an outer limiting ring 21 rotatably connected to the first sliding groove 20; a second sliding groove 22 formed on the inner side of the outer limiting ring 21; and an inner limiting ring 23 rotatably connected to the second sliding groove 22.

[0034] After the two cover plates 10 are fixedly connected to the connecting plate 12 with bolts, the cover plates 10 are installed in the designated position. Then, the shaft is passed through the through hole 11 and fixed to the inner limit ring 23. In subsequent operations, the shaft drives the inner limit ring 23 to rotate. When the inner limit ring 23 rotates 330 degrees within the outer limit ring 21, the inner limit ring 23 drives the outer limit ring 21 to rotate within the slide groove 20. After rotating another 200 degrees, the outer limit ring 21 is pressed against the slide groove 20, thereby limiting the inner limit ring 23 and the outer limit ring 21 and preventing the rotation angle from being too large, which could cause the pipeline to break.

[0035] Furthermore, the first groove 20 includes: a first groove 201 formed inside the connecting plate 12; and a second groove 202 formed inside the connecting plate 12, wherein the first groove 201 and the second groove 202 communicate with each other.

[0036] When the outer limiting ring 21 is in its initial state, it abuts against the left side of the groove 201 (direction reference). Figure 4 When the inner limiting ring 23 pushes the outer limiting ring 21 to rotate in the slide groove 20, the outer limiting ring 21 rotates along the groove 201 and rotates from the left side to the right side in a clockwise direction, for a total of 200 degrees.

[0037] Furthermore, the first groove 201 and the second groove 202 are concentric circular grooves, and the second groove 202 has an arc of 160 degrees and the first groove 201 has an arc of 220 degrees.

[0038] Furthermore, a protrusion 211 is fixedly connected to the outer side of the second groove 22, and the protrusion 211 is inserted into the groove 201.

[0039] Furthermore, a protrusion 231 is fixedly connected to the outer side of the inner limiting ring 23, and the protrusion 231 is inserted into the sliding groove 22.

[0040] Furthermore, a second protrusion 212 is fixedly connected to the inner side of the second groove 22, and the second protrusion 212 is in close contact with the third protrusion 231.

[0041] During operation, when the shaft drives the inner limiting ring 23 to rotate, the inner limiting ring 23 rotates within the second slide groove 22, simultaneously causing the third protrusion 231 to rotate against the second slide groove 22. This continues until the inner limiting ring 23 drives the third protrusion 231 to rotate 330 degrees clockwise within the second slide groove 22, at which point the third protrusion 231 contacts the second protrusion 212. The inner limiting ring 23 then continues to rotate, causing the third protrusion 231 to push the second protrusion 212, which in turn drives the outer limiting ring 21 to rotate within the first slide groove 20. This continues until the outer limiting ring 21 drives the first protrusion 211 to rotate 200 degrees within the first slide groove 20, reaching the maximum rotation angle. (Direction reference) Figure 2-4 )

[0042] Furthermore, the inner limiting ring 23 has a hole 232 to facilitate the connection of the inner limiting ring 23 to the shaft.

[0043] Furthermore, the first protrusion 211, the second protrusion 212, and the third protrusion 231 are all arc-shaped blocks, which facilitates the sliding of the first protrusion 211 in the first groove 20, and also facilitates the sliding of the third protrusion 231 in the second groove 22 while keeping it close to the second protrusion 212.

[0044] Specifically, the installation positions and sizes of protrusion 1 211, protrusion 2 212 and protrusion 3 231 can be installed in designated positions as needed, and different sizes of inner and outer limiting rings of protrusion 1 211, protrusion 2 212 and protrusion 3 231 can also be selected as needed.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
