Description

Technical Field

[0001] This utility model relates to the technical field of water vending machine accessories, specifically a new type of safe electromagnetic lock structure for water vending machines. Background Technology

[0002] As a common self-service device, the security of the door lock structure of water vending machines directly affects the hygiene of the water inside and the reliability of the equipment's operation. Most existing water vending machines use traditional electromagnetic locks, which rely on a single electromagnetic attraction to achieve locking, resulting in a simple structure. However, these electromagnetic locks are prone to weakening due to vibration or external impacts during long-term use, posing a risk of accidental opening. Furthermore, the locking tongue mechanism is often exposed externally, making it vulnerable to malicious prying or damage, resulting in insufficient security protection. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a new and safe electromagnetic lock structure for water vending machines to solve the problems mentioned in the background art.

[0004] A novel and secure electromagnetic lock structure for water vending machines includes: A fixing base has a slot at its front end, and two locking blocks are elastically connected to the inner walls of the slot. An electromagnet is attracted to one end of each locking block that is far apart from the other, and the electromagnet is embedded and fixed to the fixing base. An electromagnetic lock body fixed to the upper end of a mounting base; The armature is attached to the electromagnetic lock body and has a boss fixed at its lower end. A plug is fixed at the rear end of the boss and the plug is inserted into the slot and engaged with the locking block.

[0005] Furthermore, spring grooves are formed on both sides of the inner wall of the slot, and the locking blocks are located inside the spring grooves in a corresponding manner. A spring is connected between the locking block and the bottom of the spring groove, and the end of the locking block away from the spring is an arc-shaped end.

[0006] Furthermore, the electromagnet is embedded and fixed to the bottom of the second spring groove, and the electromagnet is located inside the second spring.

[0007] Furthermore, the insert block has slots at both ends, and the insert block is inserted into the slots.

[0008] Furthermore, a spring groove is formed at the bottom of the slot, and a spring is fixed at the bottom of the spring groove. One end of the spring extends out of the spring groove and contacts the insert block as the insert block is inserted into the slot.

[0009] Furthermore, each of the four corners of the front end of the electromagnetic lock body has a spring groove three, and a rubber pad is fixed to the front end of the electromagnetic lock body and outside the spring groove three. A spring three is fixed to the bottom of the spring groove three, and one end of the spring three protrudes from the front end of the rubber pad.

[0010] Beneficial effects: By setting an elastic locking block in the slot at the front of the fixed base and engaging with the electromagnet, combined with the attraction design of the electromagnetic lock body and the armature, a dual locking mechanism of electrical control and mechanical is formed, which effectively prevents unauthorized opening. After the plug is inserted into the slot, the locking block secures the mechanical lock. The buffer design of spring one and spring three reduces the impact wear of the components and extends the service life. The overall structure is compact and easy to install, which greatly improves the safety, stability and reliability of the water vending machine electromagnetic lock. Attached Figure Description

Detailed Implementation

[0013] Please see Figures 1-3 A novel and secure electromagnetic lock structure for water vending machines includes: A fixed base 1 has a slot 11 at its front end. Both sides of the inner wall of the slot 11 are elastically connected to a locking block 16. An electromagnet 17 is attracted and engaged at one end of the locking block 16 that is far apart from each other. The electromagnet 17 is embedded and fixed to the fixed base 1. Electromagnetic lock body 2 is fixed to the upper end of the fixed base 1; The electromagnetic lock body 2 is equipped with an armature 3 that engages with it. A boss 31 is fixed to the lower end of the armature 3, and a plug 32 is fixed to the rear end of the boss 31. The plug 32 is inserted into the slot 11 and engages with the locking block 16. Under normal conditions (when the door is closed and locked), the electromagnetic lock body 2 is always energized, generating a magnetic force to hold the armature 3 in place; while the electromagnet 17 is de-energized. When a user swipes their card to obtain water, the control system reverses this state, cutting off the power to the electromagnetic lock body 2 and simultaneously energizing the electromagnet 17.

[0014] When normally locked, the electromagnetic lock body 2 attracts the armature 3 tightly, achieving the first layer of locking. At the same time, the de-energized electromagnet 17 has no magnetic force, and the locking block 16 extends inward under the elastic force of the spring 15 and locks into the slot 33 of the insert block 32, forming the second layer of mechanical locking. Through the dual locking mechanism of electromagnetic attraction and mechanical locking, the security is greatly improved, and it can effectively resist vibration, impact and malicious prying.

[0015] When the card is swiped to open, the electromagnet 17 is energized to generate magnetic force, which attracts the card block 16 back and makes it exit from the card slot 33, thus releasing the mechanical lock. At the same time, the electromagnetic lock body 2 is de-energized and releases the armature 3. At this time, the insert block 32 can move freely in the slot 11, and the door can be pulled open.

[0016] Spring grooves 14 are formed on both sides of the inner wall of slot 11. Each locking block 16 is located inside one of the spring grooves 14. A spring 15 connects the locking block 16 to the bottom of the spring groove 14. The end of the locking block 16 away from the spring 15 is an arc-shaped end. The spring grooves 14 and springs 15 constitute the elastic reset mechanism of the locking block 16. When the electromagnet 17 is de-energized (i.e., under normal locking condition), it provides a continuous and stable elastic force to the locking block 16, ensuring that the locking block 16 can reliably pop out. The plug 16 is inserted into the slot 33 of the plug 32 to achieve mechanical self-locking. The arc-shaped end design of the front end of the plug 16 allows the plug 32 to press the arc surface of the plug 16 with its inclined surface during the closing process, even if the electromagnet 17 is not energized. This forces the plug 16 to compress the second spring 15 and move backward. After the plug 32 is fully inserted and aligned with the slot 33, the plug 16 can quickly reset and lock under the action of the second spring 15, achieving self-locking when the door is closed. No electric drive is required, making it safe and convenient.

[0017] Electromagnet 17 is embedded and fixed in the bottom of spring slot 14. Electromagnet 17 is located inside spring 15. By embedding and fixing electromagnet 17 in the bottom of spring slot 14 and placing it inside spring 15 (i.e., the center of the coil is aligned with the adsorption surface of card block 16), this arrangement can make the most efficient use of the magnetic circuit. When the card is swiped and the electromagnet 17 is energized, the generated magnetic force can act directly and efficiently on card block 16, overcoming the elasticity of spring 15 and quickly and completely pulling card block 16 back into spring slot 14. This ensures that card block 16 is completely separated from card slot 33, clearing obstacles for the withdrawal of insert block 32 and ensuring smooth opening.

[0018] Both ends of the insert block 32 have slots 33. The locking block 16 is inserted into the slots 33. The insertion and engagement of the slots 33 and the locking block 16 constitutes the most critical mechanical locking point. When the locking block 16 is inserted into the slot 33, the insert block 32 is completely locked and cannot be pulled out. This rigid mechanical interlocking method is far safer than simple electromagnetic attraction. Even if someone tries to forcibly pull the door from the outside, the pulling force acting on the insert block 32 will be directly borne by the locking block 16 and the fixed seat 1, and will not act on the electromagnetic lock body 2 or the armature 3, thus effectively preventing the possibility of opening the door by damaging the electromagnetic lock part with external force.

[0019] The bottom of slot 11 has a spring groove 12, and a spring 13 is fixed to the bottom of spring groove 12. One end of spring 13 extends out of spring groove 12. Spring 13 contacts insert block 32 as it is inserted into slot 11. Spring 13 mainly plays the role of assisting opening and buffering. In the locked state, it is compressed and stored by insert block 32. When the card is swiped to open and the mechanical locking is released (lock block 16 is retracted), the elastic potential energy stored in spring 13 will be released, generating a force that pushes insert block 32 forward. This force can assist the user in the initial action of pulling the door open, making the door tend to pop out, improving the user experience. At the same time, during the closing process, spring 13 can also play a buffering role, absorbing some impact energy and protecting insert block 32 and the bottom structure of slot 11.

[0020] The electromagnetic lock body 2 has spring grooves 21 at each of its four front corners. A rubber pad 22 is fixed to the front of the electromagnetic lock body 2 outside the spring grooves 21. A spring 23 is fixed to the bottom of the spring grooves 21. One end of the spring 23 protrudes from the front of the rubber pad 22. The spring 23 and the rubber pad 22 together form a buffer and sealing system for the electromagnetic lock's engagement surface. When the door is closed and the electromagnetic lock body 2 engages the armature 3, the spring 23 is compressed first, which can effectively absorb impact energy, prevent the electromagnetic lock body 2 from rigidly colliding with the armature 3, reduce noise and structural wear, and extend service life. The elastic deformation of the rubber pad 22 further assists in the buffering effect, ensuring the stability and reliability of the lock body under long-term and frequent use.
