The turnstile mechanism from Mairs is a whole composed of various mechanical parts inside the pedestrian turnstile gate (including the driving motor, reducer, gear, belt, electromagnetic device, etc), which uses the mechanical principle to control the opening and closing action of the turnstile gate blocking rod(blocking barrier). It is the key for the pedestrian turnstile gate to realize the functions of fast passage and anti tailing.

The turnstile mechanism is the core component and important part of the turnstile gate, and the turnstile mechanism controls the turnstile gate by controlling the swing of the blocking rod arm, which is equivalent to the heart of the turnstile gate. The operation principle of the turnstile gate is to control the opening and closing of the blocking rod by controlling the operation and stop of the mechanism, so as to realize the access control management function.

Types of Turnstile mechanism:

Before we start, you need to know different types of turnstile mechanisms, Maybe others will define or distinguish different types of turnstile mechanisms from other aspects. The turnstile gate mechanism provided by MairsTurnstile includes a tripod turnstile gate mechanism, swing turnstile gate mechanism, flap barrier turnstile mechanism, and full height turnstile gate mechanism. The design and improvement of the turnstile gate mechanism are very important for the improvement of the overall stability, quality, and humanized function of the pedestrian turnstile gate. Let’s briefly introduce types of turnstile gate mechanisms:

Full height turnstile mechanism

The full height turnstile gate mechanism is divided into a semi-automatic full height turnstile gate mechanism and an automatic mute full height turnstile gate mechanism.

The semi-automatic full height turnstile gate mechanism controls the opening and closing of the machine through the solenoid valve. Through continuous improvement, the solenoid valve is equipped with a heat dissipation device, the service life is prolonged, the shock absorber is integrated, the collision sound is reduced, and the mechanical anti reversal function is improved on the basis of the electromagnet movement, which can realize the anti reversal and buffer functions;

Its disadvantage is that there is a certain amount of noise. Because of its good performance and ultra-high cost performance, most of the full heights in the market currently use this semi-automatic full height turnstile gate mechanism.

The fully automatic mute full height turnstile gate mechanism is realized by using the motor combined with the special-shaped grooved wheel structure. When passing, it automatically rotates forward at a certain angle, and people touch the blocking rod to pass. It is a brand-new product completed by using the industrial control processing method. During the whole product operation, the start and stop are very stable, and the braking and locking can be realized quickly. It is the first mute full height turnstile gate mechanism combined with multi-channel and multi-level sensors in the industry. It has the advantages of no noise, stable operation, no mechanical wear, and long service life. Its disadvantage is that the cost is relatively high.

If you want to view the full-automatic full height turnstile gate mechanism, you can view the video at the end of the article, which contains the display of this full-automatic full height turnstile gate mechanism.

Tripod turnstile mechanism

The tripod turnstile gate mechanism is divided into a semi-automatic tripod turnstile gate mechanism and a fully automatic silent Tripod turnstile gate mechanism. The semi-automatic tripod turnstile gate mechanism is mainly composed of the main shaft, electromagnet, toothed cam, positioning cam, travel switch, damper, tension spring, and rod dropping equipment, which has the advantages of low cost and simple mechanical structure. However, due to the influence of mechanical structure, the service life is not long, and it is often affected by independent impact with high noise.

When the tripod turnstile drive plate (hereinafter referred to as the drive plate) receives the opening signal, one relay is closed and the corresponding electromagnet is turned on, which promotes the shortening of the lock arm and eliminates the determination of the toothed cam. At this time, pedestrians can pass in the direction exempted from a determination by pushing the push rod slightly.

The fully automatic mute tripod turnstile gate mechanism is mainly positioned by the sensor. There is no mechanical impact during operation. The overall structure conforms to the basic principle of mechanics and has no noise. Tripod turnstile gate mechanism with long service life and high technical requirements for the control part.
