Description

Technical Field

[0001] This utility model relates to the field of folding plug technology, specifically a locking device for folding prongs in a three-prong plug. Background Technology

[0002] As an essential item in industry and daily life, plugs are widely used. A common plug consists of a housing and a plug part. Because plugs are usually irregularly shaped, they are inconvenient to carry and package. Therefore, in order to reduce packaging space and make them easier to carry, some plugs on the market adopt a folding structure, that is, the pins or plug part can be folded relative to the housing, thereby hiding the pins or plug part in the housing, making them easier to carry and package.

[0003] This type of plug also has its drawbacks. When folded, the pins or plug may loosen and protrude from the casing during transport, making it inconvenient to carry and potentially damaging to the product. Utility Model Content

[0004] The purpose of this utility model is to provide a locking device for folded pins in a three-prong plug, so as to solve the shortcomings of the above-mentioned plugs, such as the folded pins or plug part becoming loose during carrying and protruding from the housing, which is not only inconvenient to carry, but also easy to damage the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A locking device for folded prongs in a three-prong plug includes a base plate on which three parallel prongs are rotatably disposed, with two parallel prongs on the vertical plane forming a rear prong and the other prong forming a front prong. A housing is fixedly disposed on the base plate.

[0007] A latching mechanism is fixedly mounted on the outer casing for limiting and fixing the pins in the device. The latching mechanism includes a top plate fixedly connected to the outer casing. Two parallel guide rods are fixedly mounted on the top plate. A spring is fixedly mounted on the top plate. A locking plate is fixedly mounted on the other end of the spring, and the locking plate is located between the two guide rods. The end of the pin contacts the end of the locking plate.

[0008] Preferably, the card plate is tapered with a wider bottom and a narrower top, and the end of the front foot of the insert is inclined and fits against the side of the card plate.

[0009] Preferably, a magnet plate is fixedly provided on the card plate.

[0010] Preferably, multiple parallel connecting plates are fixedly arranged at the edge of the base plate, and the sidewalls of each connecting plate are inclined, and the sidewalls of the connecting plates are provided with notches.

[0011] Preferably, a storage groove for folding the plug is provided on the lower end surface of the base plate, and the length of the storage groove is not less than the length of the plug.

[0012] Preferably, the base plate is made of polystyrene material with good insulation properties.

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

[0014] This utility model, through a locking mechanism on the outer shell, allows the operator to store the pins on the base plate via a storage slot. When using the device, the operator moves the pins, and as the front leg rotates, its end abuts against the locking plate on the outer shell. When the front leg rotates to a certain angle, it engages with the locking plate. Furthermore, the spring on the top plate ensures that the front leg has a certain horizontal force, guaranteeing normal operation of the device. When the device is not in use, the operator can move the pins to store them in the storage slot on the base plate. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] Reference Figures 1-3 A locking device for folding prongs in a three-prong plug includes a base plate 1, on which three parallel prongs 2 are rotatably disposed, with two parallel prongs 2 on the vertical plane forming a rear leg and the other prong 2 forming a front leg, and a housing 3 is fixedly disposed on the base plate 1.

[0024] A latching mechanism is fixedly mounted on the outer casing 3 to limit and fix the pin 2 in the device. The latching mechanism includes a top plate 4 fixedly connected to the outer casing 3. Two parallel guide rods 41 are fixedly mounted on the top plate 4. A spring 42 is fixedly mounted on the top plate 4. A locking plate 43 is fixedly mounted on the other end of the spring 42, and the locking plate 43 is located between the two guide rods 41. The end of the pin 2 is in contact with the end of the locking plate 43.

[0025] Reference Figures 3-5 The clamping plate 43 is tapered with a large bottom and a narrow top. The end of the front foot of the plug 2 is inclined and fits against the side of the clamping plate 43. By setting the clamping plate 43 to be tapered with a large bottom and a narrow top, the end of the front foot fits against the clamping plate 43 when the operator rotates the plug 2. The inclined end of the clamping plate 43 reduces the resistance between the clamping plate 43 and the plug 2, making it easier to control the device.

[0026] Reference Figures 1-3 A magnet plate 5 is fixedly installed on the card plate 43. By installing the magnet plate 5 on the card plate 43, when the pin 2 is perpendicular to the base plate 1, the front foot is closest to the magnet plate 5 on the card plate 43. At this time, the magnetic force of the magnet plate 5 on the front foot is the greatest, ensuring the stability of the working chamber device.

[0027] Reference Figures 1-2 Multiple parallel connecting plates 6 are fixedly installed on the edge of the base plate 1, and the side walls of each connecting plate 6 are inclined. The side walls of the connecting plates 6 are provided with notches 61. By using multiple connecting plates 6 at the edge of the base plate 1, the protective shell of the device can be snapped onto the connecting plates 6 when the device is assembled. The notches 61 on the connecting plates 6 can enhance the overall stability and safety of the device.

[0028] Reference Figures 2-4The bottom surface of the base plate 1 is provided with a storage slot 7 for placing the folding pin 2. The length of the storage slot 7 is not less than the length of the pin 2. By setting the storage slot 7 on the base plate 1, the staff can manually rotate the pin 2 set on the base plate 1 when the device is not in use, so that it can be stored in the storage slot 7 of the device, protecting the outer surface of the pin 2 from dust and impurities, and ensuring the stability of the device.

[0029] Reference Figures 1-3 The base plate 1 is made of polystyrene, which has good insulation properties, to ensure that the device has good safety.

[0030] Specifically, this solution involves: during assembly, the protective shell of the device is snapped onto the connecting plate 6. The notch 61 on the connecting plate 6 enhances the overall stability and safety of the device. When using the device, the operator can manually rotate the pin 2 on the base plate 1 via the storage slot 7, allowing it to be stored in the storage slot 7 when the device is not in use. This protects the outer surface of the pin 2 from dust and impurities, ensuring the stability of the device. When rotating the pin 2, the front end of the pin 2 is in contact with the clamping plate 43. The inclined end of the clamping plate 43 reduces the resistance between the clamping plate 43 and the pin 2, facilitating the adjustment of the device. When the pin 2 is perpendicular to the base plate 1, the front end is closest to the magnetic plate 5 on the clamping plate 43, resulting in the maximum magnetic force of the magnetic plate 5 on the front end, ensuring the stability of the working chamber device.
