Description

Technical Field

[0001] The utility model relates to the technical field of rotating electromagnets, and more specifically to a rotatable torque electromagnet. Background Art

[0002] A rotatable torque electromagnet is a rotating electromagnet. A rotating electromagnet is similar to the rotation of a motor. However, the difference between a rotating electromagnet and a motor is that a motor can continuously rotate in one direction forever, while a rotating electromagnet will not continue to rotate after it reaches a specified angle after being powered on, and will return to its original position through its own reset spring after power is cut off, thereby achieving a certain task. Because it can only rotate within a specified area, it is called a rotating electromagnet or an angle electromagnet. In terms of the direction of rotation, it can be divided into two types: clockwise and counterclockwise. Torque is the embodiment of the power generated by a rotating electromagnet when it rotates.

[0003] The existing rotatable torque electromagnet mainly uses springs to limit the pulling and resetting effects. Because the spring has a certain elastic expansion, when the rotating iron core in the electromagnet rotates to the specified point, it is easy to vibrate slightly, which will cause a slight misalignment, and it is easy to cause its rotation angle to exceed the fixed point position. If it is used in the control of some precision equipment, its slight vibration and misalignment will greatly affect the accuracy of the angular displacement of the equipment components, which is not conducive to use. In view of this, we propose a rotatable torque electromagnet. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a rotatable torque electromagnet to solve the technical problem that the current rotatable torque electromagnet is prone to vibrating displacement.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a rotatable torque electromagnet, comprising a rotating electromagnet, a rotating structure is arranged on the surface of the rotating electromagnet, a lever structure is slidably arranged on the top of the rotating structure, a gear ring is arranged on the top of the rotating electromagnet around the rotating shaft of the rotating electromagnet, a fixed structure symmetrical to the gear ring is arranged on the lever structure, and a matching rod symmetrical to the lever structure is arranged on the rotating shaft of the rotating electromagnet;

[0006] The gear rod structure includes a vertical rod and a horizontal rod. The horizontal rod is horizontally arranged at the top of the vertical rod. The vertical rod and the horizontal rod are L-shaped. The end of the horizontal rod facing the matching rod is a U-shaped end. The inner wall of the gear ring is provided with an auxiliary groove, and the bottom end of the U-shaped end extends into the auxiliary groove.

[0007] In the utility model, when the rotating electromagnet is in use, the lever structure can be displaced in the rotating structure in advance as needed, and the lever structure can be displaced to the end point of the required rotation angle of the rotating rod of the rotating electromagnet. Therefore, when the rotating electromagnet is energized, the rotating rod on the rotating electromagnet is rotated to the specified angle. At this time, the matching rod on the rotating rod of the rotating electromagnet will directly press against the lever structure, thereby realizing the fixed-point positioning of the rotating rod of the rotating electromagnet, and the situation of exceeding the fixed-point position will not occur, thereby ensuring the accuracy of its rotation angle. The end of the lever structure adopts a U-shaped end, and then the bottom end of the U-shaped end extends into the auxiliary groove, which can greatly improve the installation stability of the lever structure and avoid deformation of the end of the lever structure under force during long-term use, which leads to inaccurate positioning. Therefore, the accuracy of the fixed-point limit of the rotating rod on the rotating electromagnet by the lever structure can be further guaranteed.

[0008] Preferably, the rotating structure comprises a circular ring, an inner wall of the circular ring is arranged with an inner cavity, a displacement block is movably arranged inside the inner cavity, the vertical rod is arranged on the displacement block, and an opening is opened around the top of the circular ring.

[0009] Preferably, a matching groove is provided on the inner wall of the inner cavity, and balls symmetrical to the matching groove are movably arranged on the surface of the displacement block.

[0011] Preferably, the clamping strip is in the shape of a triangular strip, and the clamping strip matches the tooth opening of the tooth ring.

[0012] Preferably, a horizontal rod is arranged at one end of the mounting rod facing away from the clamping bar, and the horizontal rod and the mounting rod are in a T shape.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is designed with a rotating structure, a gear lever structure, a gear ring, a fixed structure and a matching rod. Therefore, when the rotating electromagnet is used, the gear lever structure can be displaced in the rotating structure in advance according to needs, and the gear lever structure can be displaced to the end point of the required rotation angle of the rotating rod of the rotating electromagnet. Therefore, when the rotating electromagnet is energized, the rotating rod on the rotating electromagnet is rotated to a specified angle. At this time, the matching rod on the rotating rod of the rotating electromagnet will directly press against the gear lever structure, thereby realizing fixed-point positioning of the rotating rod of the rotating electromagnet, and the situation of exceeding the fixed-point position will not occur, thereby ensuring the accuracy of its rotation angle, and solving the technical problem that the current rotatable torque electromagnet is prone to vibrating displacement. Therefore, the utility model has the advantage of precise positioning.

[0015] 2. The utility model also provides an auxiliary notch on the inner wall of the gear ring, and the end of the gear lever structure adopts a U-shaped end, and then the bottom end of the U-shaped end extends into the auxiliary notch, which can greatly improve the installation stability of the gear lever structure and avoid deformation of the end of the gear lever structure due to force during long-term use, which leads to inaccurate positioning. Therefore, the accuracy of the fixed-point limit of the gear lever structure on the rotating rod on the rotating electromagnet can be further guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

When the rotating electromagnet 1 is used, the lever structure 3 can be displaced in the rotating structure 2 in advance as needed, and the lever structure 3 can be displaced to the end point of the rotating angle of the rotating rod of the rotating electromagnet 1. Therefore, when the rotating electromagnet 1 is energized, after the rotating rod on the rotating electromagnet 1 is rotated to the specified angle, at this time, the matching rod 5 on the rotating rod of the rotating electromagnet 1 will directly press against the lever structure 3, thereby realizing the fixed-point positioning of the rotating rod of the rotating electromagnet 1, and the situation of exceeding the fixed-point position will not occur, thereby ensuring the accuracy of its rotation angle.

[0024] Specifically, the rotating structure 2 includes a circular ring 201, an inner wall of the circular ring 201 is arranged with an inner cavity 202, a displacement block 204 is movably arranged inside the inner cavity 202, a vertical rod 301 is arranged on the displacement block 204, and an opening 203 is opened around the top of the circular ring 201. The displacement block 204 can slide in the inner cavity 202, thereby driving the lever structure 3 to rotate and displace and adjust its position. The opening 203 facilitates the rotation of the lever structure 3.

[0025] Furthermore, a matching groove 205 is provided on the inner wall of the inner cavity 202 , and a ball 206 symmetrical to the matching groove 205 is movably arranged on the surface of the displacement block 204 .

[0026] Furthermore, the fixing structure 6 includes a mounting plate 601, which is arranged at the bottom of the cross bar 302, and a mounting rod 602 is slidably arranged on the mounting plate 601, and a clamping strip 603 is arranged at one end of the mounting rod 602 facing the gear ring 4, and the mounting rod 602 is located between the clamping strip 603 and the mounting plate 601 and is provided with a spring 604; the clamping strip 603 is in the shape of a triangular strip, and the clamping strip 603 cooperates with the tooth mouth of the gear ring 4, and under the push of the spring 604, the triangular strip 603 can be clamped into the tooth mouth of the gear ring 4 to fix the gear rod structure 3.

Therefore, the accuracy of the fixed-point limit of the rotating rod on the rotating electromagnet 1 by the gear lever structure 3 can be further guaranteed.
