Description

Technical Field

[0001] This utility model relates to the field of belt pulley protection technology, specifically an adjustable-angle belt pulley protection device. Background Technology

[0002] "Protection" refers to facilities used to isolate hazards and protect the safety of people or equipment, and is widely used in fields such as industry, information security, and personal protection.

[0003] Existing pulley protection devices typically protect pulleys by placing a protective frame over the outside of the pulley. However, when the pulley is installed at an angle, vertically, or non-standard angle in the machine, the protective frame cannot be adjusted, resulting in the frame not fitting tightly against the pulley's contour. Debris and other foreign objects can enter the pulley's transmission area through the gaps, potentially jamming the belt and causing the pulley to stop abruptly.

[0004] Therefore, an adjustable-angle pulley protection device is proposed to solve the problems mentioned above. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1 - Figure 4 An adjustable pulley protection device in this embodiment includes a housing 1 and a housing 2 movably disposed on one side of the housing 1. A connecting plate 2 is provided through one side of the housing 2 3. The end of the connecting plate 2 away from the housing 2 3 is fixedly connected to one side of the housing 1. A motor 4 is provided inside the housing 2 3. The connecting plate 2 is fixedly connected to the motor 4. A rotating plate 16 is provided at the output end of the motor 4. A fixed shaft 5 is fixedly connected to one side of the rotating plate 16. A push plate 6 is movably disposed outside the fixed shaft 5. A sliding groove is provided through one side of the push plate 6. A protective frame 7 is provided at the end of the push plate 6 near the housing 1. Two fixed rods 10 are fixedly connected to one side of the protective frame 7. A sliding ball 11 is fixedly connected to one end of each of the two fixed rods 10.

[0024] The output end of motor 14 is connected to housing 2 3 through the motor. An arc-shaped groove 14 is provided on one side of housing 1, and the sliding ball 11 is slidably connected inside the arc-shaped groove 14.

[0025] Two arc-shaped limiting plates 15 are fixedly connected to the inner side of the arc-shaped groove 14, and the sliding ball 11 is located inside the two arc-shaped limiting plates 15;

[0026] The rotating plate 16 is fixedly connected to the motor 4, the fixed shaft 5 is slidably connected inside the slide groove, and the pushing plate 6 is fixedly connected to the protective frame 7.

[0027] The rotation of the pulley 12 by the second motor 13 and the rotation of the rotating plate 16 by the first motor 4 are both existing technologies and are therefore not described in detail in this embodiment.

[0028] At this time, the rotating plate 16 is driven to rotate by the motor 4. When the rotating plate 16 rotates, it will drive the fixed shaft 5 on one side to rotate. By sliding the fixed shaft 5 to the push plate 6, as the fixed shaft 5 rotates with the rotating plate 16, it will slide inside the groove opened on one side of the push plate 6, thereby adjusting the angle of the push plate 6. By fixing the push plate 6 to the protective frame 7, the movement of the push plate 6 will drive the protective frame 7 to move synchronously, thereby adjusting the angle of the protective frame 7 and improving the flexibility of the protection. The sliding ball 11 is slidably connected to the arc groove 14, and the sliding ball 11 is fixedly connected to the protective frame 7 by the fixed rod 10, which can limit the rotation position of the protective frame 7. The structure achieves a certain effect, preventing the protective frame 7 from shaking and shifting position during rotation, thus improving structural stability. By fixing two arc-shaped limiting plates 15 to the inside of the arc-shaped groove 14, the arc-shaped limiting plates 15 can prevent the sliding ball 11 from shifting to the outside of the arc-shaped groove 14, avoiding the problem of the sliding ball 11 sliding to the outside of the arc-shaped groove 14 due to motion inertia or external force. The connecting plate 2 can achieve the effect of fixing the position of the motor 4, preventing the motor 4 from shaking during rotation, thus improving the stability of the motor 4's operation. In particular, by setting the motor 4 inside the housing 3 and sealing the through part of the motor 4's output end to the housing 3, the external environment can be prevented from affecting the operation of the motor 4, thus improving the stability of the motor 4's operation.

[0029] A rotating shaft 9 is fixedly connected to one side of the housing 1. The rotating shaft 9 is inserted into the inner side of the slide groove. Limiting plates 8 are movably provided on both sides of the push plate 6. The end of the protective frame 7 away from the limiting plate 8 is rotatably connected to the housing 1.

[0030] Both limiting plates 8 are fixedly connected to the outside of the rotating shaft 9, and the two limiting plates 8 are symmetrically distributed.

[0031] The protective frame 7 is equipped with a pulley 12, and the box 1 is equipped with a motor 2 13. The output end of the motor 2 13 is rotatably connected to the pulley 12. One end of the motor 2 13 is fixedly connected to a fixing plate, and one end of the fixing plate is fixedly connected to the inside of the box 1.

[0032] By movably setting two limiting plates 8 on both sides of the push plate 6, the axial position of the push plate 6 can be limited, preventing the push plate 6 from wobbling left and right during rotation, which would cause inaccurate angle adjustment of the protective frame 7. By inserting the rotating shaft 9 into the inner side of the slide groove, the rotation of the push plate 6 can be supported. By rotatably connecting the end of the protective frame 7 away from the limiting plates 8 to the housing 1, the problem of jamming at the other end when the angle of the protective frame 7 is adjusted at one end is prevented, thus improving the stability of operation. By rotatably connecting the output end of the second motor 13 to the pulley 12, the rotation of the pulley 12 can be controlled by controlling the start and stop of the second motor 13. The fixing plate fixedly connected to one end of the second motor 13 can fix the position of the second motor 13.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the motor 4 rotates the plate 16. While the plate 16 rotates, the fixed shaft 5 slides inside the groove at one end of the push plate 6. The push plate 6 slides in an arc shape following the sliding of the fixed shaft 5, thereby moving the protective frame 7 and achieving the effect of adjusting the angle of the protective frame 7.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
