Description
Technical field
This utility model relates to antitheft door technical field, a kind of novel magnetic anti-theft chain.
Background technology
Door chain is a kind of locking metallic bond being arranged on inside gate.Door chain, as a kind of conventional safety device strengthening door lock, is widely used among all kinds of hotel and daily house.Generally, door chain is made by metal material.During use, one end of door chain is fixed on doorframe or wall, and other end is provided with snap close, can stick on the chute being fixed on door, plays the effect strengthening door lock.
When hanging up properly door chain, door maximum can be only opened to 5 cm.In this case, people cannot pass through, and hands also cannot put in from doorway and open door chain, this guarantees owner when opening the door confirmation client's identity, will not suffer the surprise attack of the other side or swarm into.It addition, also have the design pattern replacing metallic bond with metallic rod, design and use are also in order at identical consideration.
Under normal circumstances, door chain can bring certain safeguard protection effect to user.But, there is certain potential safety hazard in existing door chain.Such as, easily cause the concussion of chain and snap close when door is by intruder's switch the most energetically, snap close may be made to disengage from the access aperture of the chute end, cause its protective action to lose efficacy.Further, time the larceny case that has been reported that in, have lawless person by using L-type steel wire or other instruments, stir snap close and disengage make door chain lose efficacy to the chute end.How to prevent the above-described problem from occurring is a problem being worth research.
Summary of the invention
The potential safety hazard caused in order to avoid the problems referred to above, this utility model provides a kind of novel magnetic anti-theft chain.
This utility model is by the following technical programs: a kind of magnetic anti-theft chain, including the fixed plate being fixed on doorframe and the chute being fixed on door；Connecting in described fixed plate has chain, chain end to be fixed with the snap close coordinated with chute；Described chute is provided with access aperture and terminal aperture, is fixed with the Magnet for adsorbing snap close in the bottom of terminal aperture.
It is further: described chute includes metallic plate；Have inside groove on described metallic plate and cover the water jacket that connect with inside groove at interior rooved face, described water jacket for one end that snap close enters have circular described access aperture, described inside groove and access aperture away from one end have the terminal aperture described in circle；Described snap close includes connector and the cylindrical cervical region fixing with connector, recess diameter and the width fits of water jacket being connected with chain；Being fixed with insert in described neck end, insert is in the form of annular discs, its diameter and access aperture and terminal aperture diametric fit.
Described Magnet is fixed on the bottom of terminal aperture.
The thickness of described Magnet is less than the terminal aperture degree of depth, forms a groove above Magnet.
Described inside groove and water jacket are vertically arranged.
Compared with prior art, the beneficial effects of the utility model are: described chute end is provided with Magnet, can snap close be inhaled in internal groove, avoid the protection caused because of chain vibration to lose efficacy, also eliminate lawless people and opened the possibility of door chain by outdoor application instrument malice, there is higher practicality.

Detailed description of the invention
The following is a specific embodiment of the present utility model, in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 4, a kind of magnetic anti-theft chain, including the fixed plate 1 being fixed on doorframe 5 and the chute 4 being fixed on door 6；Connecting in fixed plate 1 has chain 2, chain 2 end to be fixed with the snap close 3 coordinated with chute 4.Chain 2 is a metal bracelet that can bear certain pulling force.During installation, fixed plate 1 is fixed on the suitable positions such as doorframe, and chute 4 is vertically fixed on the correct position of door.The structure of chute 4 as shown in Figures 2 and 3, is made up of metallic plate 5-and Magnet 4g.Have inside groove 4b on metallic plate 5-with cover the water jacket 4c, water jacket 4c that connects with inside groove 4b on inside groove 4b surface for one end that snap close 3 enters have circular described access aperture 4a, inside groove 4b and access aperture 4a away from one end have terminal aperture 4d described in circle.Snap close 3 includes connector 3a and the cervical region 3b of the cylinder fixing with connector 3a being connected with chain 2, is fixed with discoid insert 3c in cervical region 3b end.The diameter of cervical region 3b is slightly less than the width of water jacket 4c.The diameter of insert 3c is slightly less than the diameter of access aperture 4a and terminal aperture 4d, width more than water jacket 4c and be slightly less than the width of inside groove 4b.The thickness of insert 3c is slightly less than the degree of depth of inside groove 4b.So, insert 3c can snap in chute 4 by cervical region 3b, it is to avoid coming off of snap close.Magnet 4g is tool circular strong magnet jaggy, and Magnet 4g is fixed on the bottom of terminal aperture 4d, and the thickness of Magnet 4g is less than the terminal aperture 4d degree of depth, forms a groove 4e above Magnet 4g.
When closing door chain, first snap close 3 is put into access aperture 4a of chute 4, then along the trend of chute, snap close 3 is moved the position of the terminal to chute 4, i.e. terminal aperture 4d, as shown in Figure 4.Meanwhile, Magnet 4g holds snap close 3, feeds them into groove 4e.
As long as snap close 3 is in groove 4e, under the captivation effect of gravity and Magnet, no matter how chain vibrates, or there is people relying on instrument to stir snap close outdoors, be all difficult to open door chain.
When opening door chain, first hold snap close 3 and outwards pull out, overcome the Magnet 4g captivation to snap close 3, be allowed to depart from groove 4e.Then, the trend further along chute 4 moves up snap close 3.Finally, snap close 3 is taken out by access aperture 4a of chute 4, i.e. completes opening of door chain.
