Description

A dual power supply automatic switching switch with micro switch

technical field

The utility model relates to the field of production of a dual-power automatic switching switch, in particular to the production of a dual-power automatic switching switch with a micro switch.

Background technique

Dual power supply automatic transfer switch refers to: a device controlled by a microprocessor and used for starting and switching between grid power and grid power, or grid power and generator power supply in the grid system, which can make the power supply continuous source power supply. Series dual power supply, when the common power supply suddenly fails or fails, it will be automatically switched to the backup power supply through the dual power supply switching switch, so that the equipment can still operate normally. The most common ones are elevators, fire protection, monitoring, lighting, etc.

In the existing dual power supply products, in order to control the opening and closing of the executive circuit breaker, auxiliary contacts are installed in the two circuit breakers, and the motor is rotated and stopped through the node conversion of the auxiliary contacts. , the price of auxiliary contacts in the market is very high now, which increases the production cost of dual power supply products, and because the switch needs to be disassembled, it is labor-intensive and time-consuming for the staff to operate.

Contents of the invention

The purpose of this utility model is to provide a dual power supply automatic switching switch with a micro switch to solve the problems in the above-mentioned technologies.

In order to achieve the purpose of the utility model, the utility model provides a dual power supply automatic switching switch with a micro switch, which is characterized in that it includes a bottom plate, a galvanized box, a power mechanism, a left push swing, a right push swing, a bracket, The first micro switch and the second micro switch, the galvanized box is installed on the bottom plate, the power mechanism, the left push swing, the right push swing, and the bracket are installed on the galvanized box, and the first micro switch A micro switch and a second micro switch are installed on the bracket, and the first micro switch and the second micro switch are connected in series with the motor in the power mechanism.

Wherein, the left push swing works in cooperation with the first micro switch, and the right push swing works in cooperation with the second micro switch. When the push swing stroke is in place, it touches the electric shock of the micro switch, The micro switch is powered off, and the motor in the power mechanism stops rotating.

Wherein, the first micro switch and the second micro switch are fixed on the bracket by bolts, and the bracket is fixedly connected with the galvanized box by bolts.

Compared with the prior art, the utility model installs two micro switches on the dual power supply automatic switching switch to replace the auxiliary contacts, respectively senses the stroke of the switch, and controls the rotation and stop of the motor sequentially. The price of the contact is much cheaper, which can greatly reduce the production cost, and the installation of the auxiliary contact needs to be disassembled and assembled, which is labor-intensive and time-consuming. The installation of the micro switch is convenient, which can improve the work efficiency to a certain extent and meet the needs of users. It is convenient for promotion and application in industry.

detailed description

In order to make the purpose, technical solutions and beneficial effects of the utility model clearer, the utility model will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the protection scope of the utility model.

As shown in Fig. 1 and Fig. 2, the utility model provides a double power supply automatic switching switch with a micro switch, which is characterized in that it includes a bottom plate 1, a galvanized box 2, a power mechanism 3, a left push pendulum 4, a right Push pendulum 5, support 8, first micro switch 6, second micro switch 7, described galvanized box 2 is installed on the bottom plate 1, described power mechanism 3, left push pendulum 4, right push pendulum 5, support 8 is installed on the galvanized 2 box, the first micro switch 6 and the second micro switch 7 are installed on the bracket 8, the first micro switch 6, the second micro switch 7 and the The motors in the power mechanism 3 are connected in series.

Wherein, the left push pendulum 4 cooperates with the first micro switch 6, and the right push pendulum 5 cooperates with the second micro switch 7. When the push pendulum stroke is in place, the micro switch is touched. The electric shock of the switch, the micro switch is powered off, and the motor in the power mechanism stops rotating.

Wherein, the first microswitch 6 and the second microswitch 7 are fixed on the bracket 8 by bolts, and the bracket 8 is fixedly connected with the galvanized box 2 by bolts.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
