Description

Technical Field

[0001] The utility model relates to the technical field of switch bases, in particular to a spliced ​​isolating switch base. Background Art

[0002] An isolating switch is a switching device that is mainly used for "isolating power supply, switching operation, and connecting and disconnecting small current circuits" and has no arc extinguishing function. When the isolating switch is in the open position, there is an insulation distance that meets the specified requirements and an obvious disconnection mark between the contacts; when it is in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. When installing the isolating switch, a switch base is required to install the isolating switch. However, the existing switch base cannot accommodate the card block or cover the card hole when splicing is not required, which affects the aesthetics.

When the slider slides into the slideway, it can limit the fuse in the horizontal direction to prevent it from separating in the horizontal position. The limiting mechanism seals the opening of the slideway. The two fuses are fixed together. This spliced ​​fuse facilitates the use of the fuse. In some special cases, a fuse group can be formed by splicing a single fuse, which is convenient for its use and saves costs.

A square slot 4 is provided on the installation base 1, and a limiting rod 5 is slidably installed on one side of the square slot 4. The limiting rod 5 is convenient for pressing the cover plate 2 and the square slot 4 together, so that the cover plate 2 is locked and closed, which can facilitate the protection of the switch and the line inside the installation base 1. Adjustable connecting components 6 are installed on both sides of the installation base 1. Through the adjustable connecting components 6, multiple utility models can be connected to meet different usage requirements.

[0023] The adjustable connection assembly 6 includes a mounting sleeve 601, the cylinder body is mounted on the mounting base 1, the inner wall of the mounting sleeve 601 is provided with a limited sliding groove 602, a clamping block 603 is slidably mounted between the limited sliding grooves 602, the inside of the clamping block 603 is a hollow structure, a threaded rod 604 is rotatably mounted inside the mounting sleeve 601, the threaded rod 604 is threadedly connected to the clamping block 603, the threaded rod 604 rotates, and under the limit of the limited sliding groove 602, the clamping block 603 moves, and the threaded rod 604 rotates. The rod 604 extends to one end of the mounting sleeve 601 and is fixedly provided with a hand wheel 605. By turning the hand wheel 605, the threaded rod 604 is rotated, thereby adjusting the position of the clamping block 603. The clamping block 603 can be moved out of the mounting sleeve 601, so that the clamping block 603 can be clamped with another mounting sleeve 601 of the utility model, thereby realizing the connection of multiple utility models. When not connected, the clamping block 603 can be stored in the interior of the mounting sleeve 601, thereby improving the aesthetics.

[0024] A hinged connection seat 7 is installed inside the mounting base 1, and the elastic telescopic rod 3 is hinged to the mounting base 1 through the hinged connection seat 7. Clamping holes 8 are provided on both sides of the cover plate 2, and the clamping holes 8 are consistent in size with the mounting sleeve 601, so that when the cover plate 2 is closed, the cover plate 2 is clamped with the mounting sleeve 601. A pressing plate 9 is installed on one side of the cover plate 2, and the pressing plate 9 coincides with the square clamping groove 4. Clamping grooves 10 and mounting grooves 11 are respectively provided on both sides of the square clamping groove 4. A reset spring 12 is fixedly installed inside the mounting groove 11, and the other end of the reset spring 12 is fixedly connected to the limit rod 5, and the other end of the limit rod 5 is plugged into the clamping groove 10. The mounting base A sliding hole 13 is provided on the front side of the seat 1 and on one side of the square slot 4. A moving button 14 is fixedly installed on the limiting rod 5, and the moving button 14 is plugged into the sliding hole 13.

When the connection is not needed, the clamping block 603 can be stored in the installation sleeve 601, which improves the aesthetics. When the cover plate 2 needs to be opened, the moving button 14 is moved, the limit rod 5 moves, and the reset spring 12 is compressed. When the limiting rod 5 is fully received into the mounting groove 11, the cover plate 2 maintains a certain angle with the mounting base 1 under the action of the restoring force of the elastic telescopic rod 3, thereby facilitating the inspection and examination of the circuit inside the mounting base 1. When the cover plate 2 needs to be covered, the above operation is repeated. When the limiting rod 5 is fully received into the mounting groove 11 and the cover plate 2 is rotated, the elastic telescopic rod 3 contracts. When the pressing plate 9 is pressed tightly against the bottom of the square card slot 4, the moving button 14 is released. Under the action of the restoring force of the reset spring 12, the limiting rod 5 is carded with the card slot 10, thereby facilitating the closing and locking of the cover plate 2.
