Description
Technical field
The utility model relates to safety device field, particularly, relates to a kind of door magnetism device.
Background technology
Door magnetic and electromagnetic lock, the principle of electromagnetic lock is the same with electromagnet, is the principle utilizing electric magnetisation, and when electric current is by silicon steel sheet, electromagnetic lock can produce the powerful suction absorption iron plate that holds tightly and reach the effect of locking a door.As long as slight current electromagnetic lock will produce greatest magnetic force, control the gate control system identification personnel correctly i.e. power-off afterwards of electromagnetic lock power supply, electromagnetic lock loses suction and can open the door.Because electromagnetic lock does not have complicated frame for movement and the structure of dead bolt, the path being useful in escape or fire exit door controls.It is inner with perfusion epoxy resin protection lock body.
Door magnetic utilizes and is arranged on body of wall and locks main body and be arranged on iron plate of continuing on glass door, and because lock main body and iron plate of continuing are metal material, lock main body is when carrying out adhesive to iron plate of continuing, and collision sound is excessive.In order to solving collision sound is excessive, to the large problem of glass door impact force, electromagnetism bolt and the buffer bar between electromagnetism bolt are set.Although which reduce sound when lock main body is collided with the iron plate adhesive that continues, lock main body and the suction-combining force continued between iron plate weaken.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of door magnetism device, lock main body and continue iron plate adhesive time collision sound little and the suction-combining force is strong.
The technical scheme in the invention for solving the above technical problem is:
A kind of door magnetism device, comprise lock main body and iron plate of continuing, described iron plate of continuing is provided with electromagnetism bolt, it is characterized in that: described electromagnetism bolt has many and is parallel to each other, the two ends of described electromagnetism bolt are provided with buffer bar, have lock ditch and the adjacent surface of adjacent two electromagnetism bolts is inclined-plane between adjacent two electromagnetism bolts, this inclined-plane makes the width of the end face of electromagnetism bolt be less than the width of bottom surface, described lock main body is at least provided with one with the raised line locked ditch and match.
The adjacent surface of electromagnetism bolt is inclined-plane, makes the cross section of electromagnetism bolt in echelon, the one side that namely end face of electromagnetism bolt contacts with lock main body, and corresponding one side is bottom surface.The utility model is optimized in the clamping of prior art, one, improves the position of buffer bar, is arranged on the two ends of electromagnetism bolt, it both can reduce the impulsive contact force locked main body and continue between iron plate, also can protect by opposite house body, existing structure, electromagnetism bolt its be easy to doorframe inwall and rub, inwall causes abrasion mark, buffer bar is arranged on the two ends of electromagnetism bolt, because the quality of buffer bar is soft, doorframe inwall not easy to wear; They are two years old, lock main body arranges raised line, lock main body and continue iron plate adhesive time, raised line is stuck in the lock ditch between electromagnetism bolt, adhesive between raised line and bolt, increases adhesive face, the suction-combining force strengthening lock main body and continue between iron plate, and avoid in attracting process, locking main body and continuing the movement of position occurs between iron plate, strengthen the stability of door magnetic structure; Cross section due to electromagnetism bolt is trapezoidal, is square electromagnetism bolt compared to cross section, is convenient to lock main body and sticks into lock ditch with the iron plate raised line in attracting process that continues, also increase the contact area of electromagnetism bolt and raised line, strengthen the suction-combining force.
As preferably, in order to further strengthen the suction-combining force of lock main body and iron plate of continuing, described electromagnetism bolt has three, and described raised line has two.
As preferably, while the suction-combining force strengthening lock main body and iron plate of continuing, avoid the thickness of a magnetic too thick, the degree of depth of described lock ditch has 0.15 centimetre at least and is not more than 0.5 centimetre.The lock degree of depth of ditch and the distance between electromagnetism bolt end face and bottom surface.
As preferably, described buffer bar is rubber strip.
As preferably, described buffer bar is foam strip.
To sum up, the beneficial effects of the utility model are:
1, buffer bar is arranged on the two ends of electromagnetism bolt by the utility model, and it both can reduce the impulsive contact force locked main body and continue between iron plate, protected glass door body; Also doorframe inwall not easy to wear, protects doorframe inwall.
2, the utility model arranges raised line in lock main body, lock main body and continue iron plate adhesive time, raised line is stuck in the lock ditch between electromagnetism bolt, adhesive between raised line and bolt, increase adhesive face, the suction-combining force strengthening lock main body and continue between iron plate, and avoid in attracting process, locking main body and continuing the movement of position occurs between iron plate, strengthen the stability of door magnetic structure.
3, the cross section of the utility model electromagnetism bolt is trapezoidal, is square electromagnetism bolt compared to cross section, is convenient to lock main body and sticks into lock ditch with the iron plate raised line in attracting process that continues, also increase the contact area of electromagnetism bolt and raised line, strengthen the suction-combining force.
