Abstract

The utility model relates to an electromagnet locking mechanism which is mainly composed of an outer sleeve, a rotary body, an electromagnet, a pin and springs, wherein the electromagnet, the pin and the spring are installed in a rotary body. The pin is installed in a pin groove which is radially arranged in the rotary body, and the lower section of the pin is sheathed in a spring which is used for pressing the pin to move upwards. The upper end part extends in a groove hole of a concave margin which is arranged on the inner wall of the outer sleeve. The center of a shaft of the rotary body is provided with an electromagnet support bracket in which an electromagnet core, the root end part of which is provided with the spring, is arranged. The outer ring of the support bracket is provided with an electromagnet coil, and the outer side end of the electromagnet core is positioned below the pin and can be axially moved. The utility model has the advantages of simple and reasonable structure, compactness, agile movement of the electromagnet core, less power consumption, etc.

Description

Locked with electromagnet mechanism

Technical field

The utility model relates to a kind of locking mechanism of dynamo-electric locking mechanism, especially electromagnet, be applicable in the switch lockset series products.

Background technology

Traditional dynamo-electric locking mechanism includes overcoat, rotor and is installed in rotor interior electromagnet and pin, spring etc.; There is spring on the top of pin and is pressed in pin downwards, the leading section of pin is close on the electromagnet core that is horizontally placed on the rotor shaft center, iron core is subjected to resistance in moving process, thereby its motion is malfunctioning sometimes, also can cause the power consumption of electromagnet to increase simultaneously.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple and reasonable for structure, compact, and electromagnet core moves flexibly, the locked with electromagnet mechanism that power consumption is few.This locking mechanism mainly is made up of overcoat, rotor and the electromagnet and pin, the spring that are installed in the rotor, in the pin grooves that radially is provided with in the described rotor pin is installed, the hypomere of this pin is inserted in its spring that moves up of roof pressure, and the upper end is stretched in the recessed edge slotted eye that is provided with on outer casing inner wall.

Described rotor shaft center is equipped with electromagnet stent, is placed with the electromagnet core that a radicle has spring in the support, and the outer ring of support is provided with electromagnet coil, and the outboard end of electromagnet core is positioned at the below of pin and can moves axially.

Characteristics such as the utility model belongs to improvements over the prior art, and it has simple and reasonable for structure, compact, and electromagnet core moves flexibly, and power consumption is few.

Description of drawings

Fig. 1 is the structural representation of the utility model locking state.

Fig. 2 is the structural representation that the utility model lock is opened state.

Fig. 3 is that the A-A overcoat of Fig. 2 cuts open and shows structural representation.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing, the utility model mainly is made up of overcoat 1, rotor 2 and the electromagnet and pin 7, the spring 8 that are installed in the rotor, in the pin grooves 9 that radially is provided with in the described rotor pin 7 is installed, the hypomere of this pin 7 is inserted in its spring that moves up 8 of roof pressure, and the upper end is stretched in the recessed edge slotted eye 10 that is provided with on overcoat 1 inwall.

2 centers of described rotor are equipped with electromagnet stent 4, are placed with the electromagnet core 6 that a radicle has spring 5 in the support 4, and the outer ring of support 4 is provided with electromagnet coil 3, and the outboard end of electromagnet core 6 is positioned at the below of pin 7 and can moves axially.

In the normal state, as shown in Figure 1, because of pin 7 blocks, can not freely relatively rotate between overcoat 1 and the rotor 2, mechanism is lockable.When connecting power supply, electromagnetic actuation, iron core 6 is to left movement, electromagnet stent right-hand member slot milling, as shown in Figure 2, this moment is when rotating rotor 2, the recessed edge slotted eye 10 of overcoat 1 top is depressed pin 7, as shown in Figure 3, pin is moved downward, and all enter in the rotor, at this moment rotor 2 and overcoat 1 can freely relatively rotate.

Claims (2)

1, a kind of locked with electromagnet mechanism, it mainly is made up of overcoat, rotor and the electromagnet and pin, the spring that are installed in the rotor, in the pin grooves (9) that it is characterized in that radially being provided with in the described rotor (2) pin (7) is installed, the hypomere of this pin (7) is inserted in its spring that moves up (8) of roof pressure, and the upper end is stretched in the recessed edge slotted eye (10) that is provided with on overcoat (1) inwall.

2, locked with electromagnet according to claim 1 mechanism, it is characterized in that described rotor (2) axle center is equipped with electromagnet stent (4), be placed with a radicle in the support (4) electromagnet core (6) of spring (5) is arranged, the outer ring of support (4) is provided with electromagnet coil (3), and the outboard end of electromagnet core (6) is positioned at the below of pin (7) and can moves axially.
