Abstract

An electric door comprises a positive and reverse motor, a band brake and three control buttons for raising, descending and intermediate position respectively, wherein three limit switches are provided, with an intermediate limit switch (SQ2) being disposed between an upper end switch (SQ1) and a lower end switch (SQ3). The electric door can be operated to reach a half-opened position by only pressing the control button for intermediate position one time.

Description

Electric door technology

The utility model relates to an electric door, in particular to a new type of electric door suitable for a garage, a shop, a factory building, a warehouse, a shopping mall and the like.

Background technique

The traditional electromechanical integrated electric door featuring positive and negative reversal requires two buttons to be pressed during the half-open operation of the electric door. The rising process is taken as an example: first press the up button SB1, then press The stop button SB3 can complete the action, and the operation is cumbersome, and often only the up button or the down button SB2 is used, so energy is wasted. FIG. 1 is a schematic structural view of a conventional electric gate positive reversing circuit.

Utility model content

The utility model is proposed to solve the above problems, and an object of the utility model is to provide a kind of one that can be used in a half-open operation during an ascending process of an electric door on various buildings. New electric door.

In order to achieve the above object, the technical solution of the present invention solves the technical problem: including a forward and reverse circuit, and three control buttons, one of which is a rising button, one is a down button, and one middle button, and a brake holding brake, A stopper SQ2 is disposed between the upper and lower limiters SQ1 and SQ3.

The limiters SQ1, SQ2, and SQ3 are respectively connected to the position selection switches SA1, SA2, and SA3, and the upper and lower limiter movable contact series series switch lights HL1, HL3, and the intermediate position selection switch are connected in series with the infrared lamp HL2.

Compared with the prior art, the utility model has the following advantages and effects:

Confirmation Since the limiter SQ2 is set between the upper and lower limiters SQ1 and SQ3, the process of raising and lowering the electric door of the transfer is solved, and the button needs to be pressed twice when performing the half-open operation, taking the ascending process as an example: Press the up button, then press the stop button to complete the action, effectively overcoming the traditional use of the above three buttons to form the mode caused by the operation is cumbersome, often only use the rise button or only use the down button, so waste Energy. The utility model only needs to press the middle button once to complete the electric door half-open operation. It is extremely convenient for users, saves energy, and has wide social benefits.

DRAWINGS

The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. FIG. 1 is a schematic structural view of a conventional electric door positive and negative reversing circuit.

2 is a schematic structural view of a power gate control circuit of the present invention.

detailed description

2 is a schematic diagram of the structure of the electric door control circuit of the present invention, including a forward and reverse circuit, and three control buttons, one of which is a rise button, one is a down button, and one middle button, and a brake The gate is provided with a stopper SQ2 between the upper and lower limiters SQ1 and SQ3. The limiters SQ1, SQ2, and SQ3 are respectively connected to the position selection switches SA1, SA2, and SA3, and the upper and lower limiter movable contact series series switch lights HL1, HL3, and the intermediate position selection switch are connected to the infrared lamp HL2.

The up button SB1 and the limiter switch SA1 overlap, and the same applies to the SB2 and the SA3, so that the up button and the down button are formed, and the intermediate position selection switch SA2 and the infrared lamp HL2 are overlapped to form an intermediate button, which is up and down. Button. The upper limit is set to the lowering circuit connected to the induction lamp HL1, and the effect is that the intermediate position selection button becomes the down button. The lower limit sets the rising circuit connected to the sense lamp HL3, and the effect is that the intermediate position selection switch becomes the up button.
