Abstract
Description
Technical Field
[0001] This utility model relates to the field of electromagnet technology, and in particular to a striking electromagnet that provides high reliability. Background Technology
[0002] The striking electromagnet is a combination of the suction cup electromagnet and the push-pull electromagnet, integrating the characteristics of both. Through the magnetic field of the coil and the fixed iron core, one end of the lever plate is attracted down, while the other end of the striking plate is raised, just like pressing a seesaw, thus achieving a distributing function.
[0003] Most existing striking electromagnets are like Figure 4-6 As shown, the center of gravity of the magnetic tongue is generally located in the middle. In a high-vibration environment, the magnetic tongue is prone to malfunction due to shaking. Moreover, the magnetic tongue is engaged with the electromagnet frame (or riveted) to achieve the lever movement of the magnetic tongue. There are also spring hooks on the electromagnet frame for connecting the spring. However, the length of the spring hook is less than the diameter of the spring. Under high-vibration conditions, the spring hook may detach from the spring coil due to inertia, which poses a certain risk. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a high-reliability striking electromagnet. The center line of gravity of the magnetic tongue is adjusted to be in the same vertical plane as the center lines of gravity of the two rotation axes, breaking the traditional magnetic tongue center line layout and improving the magnetic tongue's anti-vibration interference capability from a mechanical principle perspective. The magnetic tongue is rotatably connected to the frame on both sides through a rotation axis. Such a connection structure is not easy to fall off in a high-vibration environment. The spring hook flattening design forms a flattened part, the length of which is greater than the diameter of the spring, so that the spring does not fall off. The size relationship between the hook and the spring coil is changed to structurally prevent the spring from disengaging.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a high-reliability striking electromagnet is provided, including a frame and an electromagnet body mounted on the frame. The feature is that a magnetic tongue is rotatably mounted on the side of the upper end of the frame. The two sides of the magnetic tongue are rotatably connected to the frame through a rotating shaft. The center line of gravity of the magnetic tongue and the center lines of gravity of the two rotating shafts are located in the same vertical plane. A spring connected to one end of the magnetic tongue is installed on the outside of the frame. The electromagnet body is located below the other end of the magnetic tongue.
[0006] As a supplement to the technical solution described in this utility model, a hollow is provided on the free end of the magnetic tongue, and the tail of the magnetic tongue is hollowed out to form a hollow so that the center line of gravity of the magnetic tongue and the center lines of gravity of the two rotation axes are located in the same vertical plane.
[0007] As a supplement to the technical solution described in this utility model, a lower hook is provided on the outer side of the magnetic tongue, with the free end of the lower hook bent downwards. An upper hook is provided on one end of the magnetic tongue, with the free end of the upper hook bent upwards. The two ends of the spring are respectively engaged with the lower hook and the upper hook.
[0008] As a supplement to the technical solution described in this utility model, both the free end of the lower hook and the free end of the upper hook are provided with a flat, flapping portion, the length of which is greater than the diameter of the spring.
[0009] As a supplement to the technical solution described in this utility model, a through hole is provided on the outer wall of one side of the frame, and the lower hook is provided at the bottom of the through hole.
[0010] As a supplement to the technical solution described in this utility model, a notch is provided at one end of the magnetic tongue, and the upper hook is disposed in the notch.
[0011] As a supplement to the technical solution described in this utility model, a notch 2 is opened on both sides of the magnetic tongue, and a rotating shaft is installed in each notch 2. A ring corresponding to the rotating shaft is provided on the side of the upper end of the frame.
[0012] As a supplement to the technical solution described in this utility model, the other end of the magnetic tongue is provided with an upwardly curved bend.
[0013] As a supplement to the technical solution described in this utility model, the frame is U-shaped, and a mounting plate is provided on the outer side of the frame, and the mounting plate has fixing holes.
[0014] As a supplement to the technical solution described in this utility model, a counterweight is provided at the end of the magnetic tongue that is connected to the spring.
[0015] Beneficial effects: This utility model relates to a striking electromagnet that provides high reliability, and has the following advantages:
[0016] 1. Adjusting the center line of gravity of the magnetic tongue to be in the same vertical plane as the center lines of gravity of the two rotation axes breaks the traditional magnetic tongue center of gravity layout of electromagnets and improves the magnetic tongue's anti-vibration interference capability from a mechanical principle. This is the key mechanical basis for achieving high reliability operation of electromagnets.
[0017] 2. By changing the shape of the magnetic tongue, creating a hollow in the front of the magnetic tongue, or adding a counterweight at the tail of the magnetic tongue, the center of gravity of the magnetic tongue is shifted backward, so that the center line of gravity of the magnetic tongue and the center lines of gravity of the two rotation axes are in the same vertical plane. This makes the structure more reliable and ensures that the acceleration required for the magnetic tongue to shake is significantly increased in harsh environments such as high vibration, while reducing the occurrence of malfunctions.
[0018] 3. The magnetic tongue is rotatably connected to the frame on both sides via a rotating shaft. This connection structure makes it less likely to fall off under high vibration conditions.
[0019] 4. The flattened part is formed by the flattening design of the spring hook. The length of the flattened part is greater than the diameter of the spring, so that the spring will not fall off. The size relationship between the hook and the spring ring is changed, which structurally prevents the spring from falling off the hook. Attached Figure Description

[0032] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0033] The embodiments of this utility model relate to a striking electromagnet that provides high reliability, such as... Figure 1-11 As shown, the device includes a frame 2 and an electromagnet body 1 mounted on the frame 2. A magnetic tongue 4 is rotatably mounted on the upper side of the frame 2. The magnetic tongue 4 is rotatably connected to the frame 2 on both sides through a rotating shaft 5. This connection structure is not easy to fall off in a high vibration environment. The center line of gravity of the magnetic tongue 4 and the center lines of gravity of the two rotating shafts 5 are located in the same vertical plane. A spring 3 connected to one end of the magnetic tongue 4 is mounted on the outside of the frame 2. The electromagnet body 1 is located below the other end of the magnetic tongue 4.
[0034] The center of gravity line refers to the line between the suspension point of the object and the ground.
[0035] The magnetic tongue 4 has a hollow 8 at its free end, and a counterweight 10 is provided at the end of the magnetic tongue 4 connected to the spring 3. By changing the shape of the magnetic tongue 4, creating a hollow 8 at the head of the magnetic tongue 4, or adding a counterweight 10 at the tail of the magnetic tongue 4, the center of gravity of the magnetic tongue 4 is shifted backward, so that the center of gravity line of the magnetic tongue 4 is located in the same vertical plane as the center of gravity lines of the two rotation axes 5, thus making the structure more reliable. Principle: As follows Figure 7 As shown, by changing the counterweight of the magnetic tongue 4, the center of gravity of the magnetic tongue 4 is shifted to the vertical plane where the center of gravity of the two rotation axes 5 are located, making it more reliable in the event of malfunction under high vibration. Figure 6 As shown, the original structure's center of gravity is far from the rotation axis 5. Under vibration conditions, it generates an inertial force F due to acceleration a, and its long lever arm makes it easier to sway. The adjusted structure requires a greater acceleration to make the magnetic tongue 4 sway, so it is more reliable.
[0036] Reference Figure 10 As shown in the simplified diagram, the triangle represents the center of gravity of the rotation axis. Before the change, the gravity F1 = m1a1, and the lever arm is L1. (Refer to...) Figure 11 As shown, after changing the counterweight of the magnetic tongue, the gravity F2 = m2a2, the lever arm is L2, the elastic force is F_elastic, and the elastic lever arm is L; during vibration, before the change: F1*L1 = F_elastic*L → m1a1L1 = F_elastic*L; after the change: F2*L2 = F_elastic*L → m2a2L2 = F_elastic*L.
[0037] The following is a comparative example: After changing the magnetic tongue, m1*1.2=m2, L1*0.1=L2;
[0038] m1a1L1=m2a2L2→m1a1L1=1.2m1*a2*0.1L1;
[0039] a1 = 0.12a2;
[0040] a1 / 0.12 = a2;
[0041] 8.3a1=a2.
[0042] After the above comparison, it is clear that by changing the structure, it can resist more than 8 times the original acceleration. The structure of this utility model can increase the ability to resist acceleration during vibration.
[0043] The magnetic tongue 4 is provided with a lower hook 6 on its outer side, with the free end of the lower hook 6 bent downwards. The magnetic tongue 4 is provided with an upper hook 7 on one end, with the free end of the upper hook 7 bent upwards. The two ends of the spring 3 are respectively hooked to the lower hook 6 and the upper hook 7.
[0044] Both the free end of the lower hook 6 and the free end of the upper hook 7 are provided with a flat, flapping portion 9, the length of which is greater than the diameter of the spring 3. For example... Figure 9 As shown, the free ends of the lower hook 6 and the upper hook 7 are flattened after being caught by the spring 3 to form a flattened part 9. The length of the flattened part 9 is greater than the diameter of the spring 3, so that the spring 3 does not fall off; the original structure is referenced. Figure 8 As shown, the length of the hook is less than the diameter of the spring. Under high vibration conditions, the spring hook will detach from the spring coil due to inertia. The modified structure is to hang the spring on the original basis and then flatten the hook to form a flattened part 9, making its length greater than the diameter of the spring coil 3 so that it cannot fall off.
[0045] The spring 3 is made of a high-elasticity, fatigue-resistant alloy material, which improves the performance stability of the spring 3 in high vibration environment and prevents the spring 3 from breaking or dislodging due to fatigue.
[0046] A through hole 15 is provided on the outer wall of one side of the frame 2, and the lower hook 6 is provided at the bottom of the through hole 15.
[0047] The magnetic tongue 4 has a notch 13 at one end, and the upper hook 7 is set in the notch 13.
[0048] The magnetic tongue 4 has a notch 11 on both sides, and a rotating shaft 5 is installed in each notch 11. The upper side of the frame 2 is provided with a ring 14 that corresponds to and cooperates with the rotating shaft 5.
[0049] The other end of the magnetic tongue 4 is provided with an upwardly curved bend 12.
[0050] The frame 2 is U-shaped, and a mounting plate 16 is provided on the outer side of the frame 2. The mounting plate 16 has fixing holes 17. The mounting plate 16 is fixed by fasteners through the fixing holes 17, thereby realizing the installation of the frame 2.
[0051] This utility model has the following advantages: 1. Significantly improved reliability: Extensive experimental verification shows that the improved striking electromagnet has a lower frequency of malfunctions under high vibration environments, and the probability of structural component detachment is close to zero, greatly improving the reliability and stability of equipment operation; 2.

Significantly reduced maintenance costs: Due to the significant reduction in failure frequency, the equipment maintenance cycle is extended, and maintenance costs are reduced by more than 50%, reducing enterprise operating costs and improving economic efficiency; 4. Enhanced product competitiveness: The striking electromagnet using this technology has a clear advantage in the market, significantly improving the performance and quality of related equipment, helping enterprises stand out in high-end market competition, and increasing product added value and corporate brand image.
