Description

Novel electromagnetic lock device

Technical Field

The utility model relates to a device, especially a new-type electromagnetic lock device.

Background

At present, in people's daily life, unmanned locker is more and more common, for example the locker of using such places as express delivery cabinet or supermarket to and mailbox, automatic sales counter etc. among the prior art, generally adopt the electromagnetic lock in the locker, the electromagnetic lock is the tool to lock that drives the spring bolt removal through electromagnetism production magnetic force, owing to need not driving source such as motor, therefore the overall structure of electromagnetic lock is less relatively, can satisfy the operation requirement of locker.

The existing electromagnetic lock is complex in internal structure design, poor in pushing force and prone to being locked by a lock body, so that the cabinet door cannot be opened, and the cabinet door is not favorable for customers to use pleasantly.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve above-mentioned prior art's shortcoming, provide a new-type solenoid valve device that structural strength is high, stability is good, the smooth and easy card that does not block is opened the door, satisfied client's stable, the demand that does not block when with express delivery cabinet, locker.

The utility model provides a technical scheme that its technical problem adopted: the novel electromagnetic lock device comprises a lock shell, wherein an electromagnetic switch is fixed in the lock shell, a trigger tongue is rotationally connected in the lock shell, a cross rod which is inserted on a pull rod of the electromagnetic switch is fixed at the side end of the trigger tongue, a locking tongue which is rotationally connected on the lock shell is arranged at the side end of the trigger tongue, a hook groove is formed in the top end of the locking tongue, a blocking body which is matched with the hook groove is arranged at the left end of the trigger tongue, an upper lock tongue is slidably connected at the lock shell, a first compression spring which drives the upper lock tongue to move towards the side direction of the locking tongue is installed on the lock shell, an arc-shaped hook part is arranged on the locking tongue, a second blocking body which is matched with the arc-shaped hook part is arranged on the upper lock tongue, a lock hook channel is formed at the lock shell, and a touch block which is fixed on the locking tongue is arranged at the lock hook channel. The lock shell has the function of installing and resetting all parts of the device; the electromagnetic switch has the effects that the electromagnetic force after being electrified can drive the pull rod on the electromagnetic switch to move downwards and compress the compression spring on the electromagnetic switch, the electromagnetic force disappears after being powered off, the spring on the electromagnetic switch can drive the pull rod to reset upwards, so that the cross rod can be driven to pull downwards, and the trigger tongue can be driven to rotate; the trigger tongue, the locking tongue, the hook groove and the blocking body have the effects that the blocking body can be used for blocking the locking tongue to continuously rotate anticlockwise, so that the lock hook can be tightly hooked at the position of the touch block and cannot be separated; the upper lock tongue, the second blocking body and the arc-shaped hook part have the effects that the second blocking body is driven to move by utilizing the movement of the upper lock tongue, and the arc-shaped hook part can be driven to move, so that the locking tongue can be driven to rotate anticlockwise; the latch hook channel and the touch block are used for hooking the latch hook on the touch block through the latch hook channel, so that the cabinet body is locked.

Further perfection, the lock shell is transversely inserted with the ejector rod, and the lock shell is provided with a second compression spring which drives the ejector rod to move towards the outer side of the lock hook channel. The ejector rod and the second compression spring have the effects that the ejection force on the cabinet door can be greatly increased, so that the situation that the cabinet door is blocked and cannot be opened is avoided.

Further perfection, install micro-gap switch in the lock shell, be provided with on the locking tongue with micro-gap switch press board complex boss portion. The micro switch and the boss part have the functions that the pressing plate of the micro switch can be pressed by the boss part; after the locking tongue is locked in place, the trigger tongue clamps the locking tongue under the action of the downward thrust of the electromagnetic switch spring and plays a role in locking, and meanwhile, the boss part on the locking tongue rotates anticlockwise to touch the pressing plate pressed on the microswitch, so that a signal for closing the cabinet door is given; when the electromagnetic switch is turned on and the pull rod is utilized to pull the cross rod to move downwards, the trigger tongue is driven to rotate clockwise, the locking tongue can move leftwards under the action of the elastic force of the first compression spring and push the locking tongue to rotate clockwise to a position, the locking hook is ejected out to be unlocked, and the microswitch resets to give an opening signal to the cabinet door.

The utility model discloses profitable effect is: the utility model has the advantages of ingenious, reasonable structural design, utilize and utilize electromagnetic switch to drive the pull rod and move down to the pulling horizontal pole moves down, and then drives and triggers tongue clockwise rotation, when triggering tongue clockwise rotation, can make horizontal pole and collude the groove and break away from, thereby through first compression spring's spring action, can promote latch hook and locking tongue fast, thereby make the latch hook released fast, and the locking tongue clockwise rotates, thereby micro-gap switch resets and gives the cabinet door and opens the signal, is worth popularizing and applying.
