Description

Technical Field

[0001] This utility model relates to the field of household air switch technology, specifically a household air switch with a locking structure. Background Technology

[0002] A household air switch, also known as an air circuit breaker, is a type of circuit breaker that automatically disconnects when the current in the circuit exceeds the rated current. Air switches are a very important electrical appliance in low-voltage power distribution networks and electric drive systems, integrating control and multiple protection functions.

[0003] Current household circuit breakers typically require manual operation to turn on when in the off position. However, during circuit inspection or maintenance, the circuit needs to be turned off. Current household circuit breakers lack a locking mechanism after being turned off, making them prone to accidental opening by hand, thus posing a safety hazard. Therefore, we propose a household circuit breaker with a locking mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a household air switch with a locking structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a household air switch with a locking structure, comprising an air switch body, a toggle switch being provided on the top of the air switch body, a semi-circular support plate being integrally provided symmetrically on the top of the air switch body, and a locking component being provided on the side wall of the semi-circular support plate for locking the toggle switch in the closed state.

[0006] Preferably, the locking assembly includes a fixed box, the fixed box is fixedly connected to the side of the semi-circular support plate away from the toggle switch, and a slide plate is slidably connected inside the fixed box. A slide rod is fixedly connected to one side of the slide plate, and the end of the slide rod slides through the fixed box. A spring is sleeved on the outside of the slide rod, and the two ends of the spring are fixedly connected to the inner wall of the fixed box and the slide plate, respectively. A tongue-shaped locking block is integrally provided on the side of the slide plate away from the slide rod. A slot is opened on the side wall of the toggle switch, and the tongue-shaped locking block slides through the semi-circular support plate and locks into the slot on the side wall of the toggle switch.

[0007] Preferably, a pull ring is fixedly connected to one end of the slide rod located outside the fixed box.

[0008] Preferably, the fixing box is fixedly installed on one end of the toggle switch in the closed state on the surface of the semi-circular support plate, and the right-angled surface of the tongue-shaped block is located at one end of the toggle switch in the closed state.

[0009] Preferably, the surface of the semi-circular support plate is provided with an arc-shaped sliding groove, and the top of each side wall of the toggle switch is integrally provided with a limit block, and the limit block is slidably connected in the arc-shaped sliding groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the locking component, this utility model ensures that the toggle switch will not be accidentally turned on again when it is closed, avoiding the risk of electrical failure caused by accident. The design of the spring and tongue-shaped locking block can effectively lock the switch and prevent accidental operation, while the pull ring setting makes it convenient for users to operate with one hand when needed. In addition, the cooperative design of the limit block and the arc-shaped slide groove makes the toggle switch smoother during use, avoiding jamming or displacement, and improving the overall operational stability.

[0015] 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.

[0016] Please see Figure 1 This utility model provides a technical solution: a household air switch with a locking structure, including an air switch body 1, a toggle switch 2 is provided on the top of the air switch body 1, a semi-circular support plate 3 is integrally provided symmetrically on the top of the air switch body 1, and a locking component 4 is provided on the side wall of the semi-circular support plate 3 for locking the toggle switch 2 in the closed state.

[0017] It should be noted that the locking component 4 can fix the position of the closed toggle switch 2 to prevent the toggle switch 2 from being pushed due to accidental contact.

[0018] Please see Figure 1 and Figure 2 The locking assembly 4 includes a fixed box 6. The fixed box 6 is fixedly connected to the side of the semi-circular support plate 3 away from the toggle switch 2. The fixed box 6 is slidably connected to the fixed box 6. The side of the sliding plate 7 is fixedly connected to a sliding rod 8. The end of the sliding rod 8 slides through the fixed box 6. A spring 9 is sleeved on the outside of the sliding rod 8. The two ends of the spring 9 are fixedly connected to the inner wall of the fixed box 6 and the sliding plate 7, respectively. A tongue-shaped locking block 10 is integrally provided on the side of the sliding plate 7 away from the sliding rod 8. A slot is opened on the side wall of the toggle switch 2. The tongue-shaped locking block 10 slides through the semi-circular support plate 3 and locks into the slot on the side wall of the toggle switch 2.

[0019] It should be noted that when the toggle switch 2 on the air switch body 1 is closed, it is only necessary to move the locking component 4 at one end of the semi-circular support plate 3 of the toggle switch 2 in the direction of the toggle switch 2. During the process of pushing the toggle switch 2, the tongue-shaped locking block 10 is locked into the slot on the side wall of the toggle switch 2 under the action of the spring 9, so that the toggle switch 2 is locked and prevented from being accidentally touched and opened. When the toggle switch 2 is opened again, two fingers of one hand pull the pull ring 11 inward and outward to make the tongue-shaped locking block 10 extend into the fixing box 6. At this time, the other hand can push the toggle switch 2 to open. During the process of the toggle switch 2 being moved, the two limiting blocks 5 on it slide in the arc-shaped sliding grooves 12 on the two semi-circular support plates 3 respectively, so that the toggle switch 2 will not deviate in direction when it is moved, which avoids the situation of the toggle switch 2 being stuck to a certain extent.

[0020] Please see Figure 2 A pull ring 11 is fixedly connected to one end of the slide bar 8 located outside the fixed box 6.

[0021] It should be noted that the pull ring 11 is designed to facilitate pulling the slide bar 8, which in turn pulls the tongue-shaped locking block 10, causing the tongue-shaped locking block 10 to disengage from the slot on the toggle switch 2, thus putting the toggle switch 2 in the unlocked state and making it easier to push the toggle switch 2 to open.

[0022] Please see Figure 1 The fixing box 6 is fixedly installed on one end of the toggle switch 2 in the closed state on the surface of the semi-circular support plate 3, and the right angle surface of the tongue-shaped block 10 is located at one end of the toggle switch 2 in the closed state.

[0023] It should be noted that this setting can push the tongue-shaped locking block 10 into the fixed box 6 during the closing process of the toggle switch 2, and the spring 9 is compressed. When the toggle switch 2 is in the closed position, the slot on the toggle switch 2 is located at the tongue-shaped locking block 10. Under the action of the spring 9, the tongue-shaped locking block 10 is pushed into the slot of the toggle switch 2, which can lock the position of the toggle switch 2.

[0024] Please see Figure 1 and Figure 3 The surface of the semi-circular support plate 3 is provided with an arc-shaped groove 12. The top of each side wall of the toggle switch 2 is integrally provided with a limit block 5, and the limit block 5 is slidably connected in the arc-shaped groove 12.

[0025] It should be noted that during the toggle switch 2 being toggled, the two limiting blocks 5 on it slide within the arc-shaped grooves 12 on the two semi-circular support plates 3, so that the toggle switch 2 will not deviate in direction when toggled, thus avoiding the situation where the toggle switch 2 gets stuck to a certain extent.
