As illustrated in figs. 13-15, drive device 5 includes electromagnet 51, function solenoid axle 52 and the axis of rolling 53.Function solenoid
Axle 52 with ferromagnetic material by being made, such as iron etc..Electromagnet 51 is fixed on mounting bracket 2, specifically, can pass through spiral shell
Fixing hole 23 on bolt and mounting bracket 2 fixes electromagnet 51.Work as electromagnetism close to electromagnet 51 in one end of function solenoid axle 52
When iron 51 is powered, electromagnet 51 produces magnetic field, can attract function solenoid axle 52, make the horizontal movement of function solenoid axle 52.Electromagnetism
The other end of functional shaft 52 is provided with the axis of rolling 53, and the axis of rolling 53 can rotate freely, and the axis of rolling 53 and function solenoid axle 52 are into T
Character form structure.Specifically, as shown in figure 16, one end of function solenoid axle 52 forms through hole, and the axis of rolling 53 is inserted into the through hole
In, leave gap between the outer wall and through-hole wall of the axis of rolling 53.Drive device 5 is arranged in mounting bracket 2, function solenoid axle 52
The interval that puts between two kinks 32 of end, the axis of rolling 53 is arranged on the obtuse angle one that matrix 31 is formed with kink 32
Side, and form chi structures with two kinks 32.Limited block 22 on the inwall of mounting bracket 2 plays spacing work to the axis of rolling 53
With preventing function solenoid axle 52 to be inclined to the side of buckle 3 too much.When function solenoid axle 52 can be attracted by electromagnet 51, electromagnetism
Functional shaft 52 is away from the direction horizontal movement of buckle 3, and the axis of rolling 53 also follows motion.In motion process, the axis of rolling 53
All the time contact and rolled on kink 32 with kink 32, pressure is applied to kink 32, and then buckle 3 is around steady pin
34 rotate.The free end of kink 32 is provided with positive stop hook 321.Positive stop hook 321 plays position-limiting action, can prevent function solenoid axle 52
The axis of rolling 53 departs from from kink 32 during motion.
Operationally, housing 1 is fixed on doorframe, is connected between sliding block 4 and door by a linkage, and door is provided with
Spring.When door is rotated, connecting rod band movable slider 4 is slided in housing 1, until the coupler body 42 on sliding block 4 and the roller 33 of buckle 3
It is mutually clamped, now the transfixion of sliding block 4, door is in normally open.When electromagnet 51 is powered, electromagnet 51 produces magnetic field,
Attract the horizontal movement of function solenoid axle 52, the axis of rolling 53 rolls on kink 32 and applies pressure to kink 32, makes buckle 3
Rotated around steady pin 34, and then the coupler body 42 of the disengaging sliding block 4 of roller bearing 33 of buckle 3, the sliding block 4 for departing from the limitation of buckle 3 can
Slidably, under the spring force effect on door, door realizes automatic close.Electromagnet 51 is powered off after door is closed, and magnetic field disappears
Lose, buckle 3 is rotated backward and resetted under gravity.
In some embodiments, as shown in figure 5, matrix 31 includes L-shaped kink 315, L-shaped kink 315 is located at base
The end of body 31, the coupler body 42 formed between L-shaped kink 315 and roller bearing 33 on groove 316, sliding block 4 can be placed on groove
In 316, buckle 3 can be made to engage with sliding block 4 more accurate and firm.The gravity of L-shaped kink 315 also helps answering for buckle 3
Position.As shown in figs. 17-18, door closer-holder of the invention also includes resetting means 6, and resetting means 6 includes bolt 61 and resetted
Spring 62, back-moving spring 62 is set on bolt 61.The mounting hole through the upper and lower surface of buckle 3 is offered on L-shaped kink 315
3151, bolt 6 is inserted in mounting hole 3151 from bottom to top, and mounting bracket 2 is provided with bolt hole 24, the upper end of bolt 61 and bolt hole
24 coordinate.Buckle 3 rotates the meeting compression reseting spring 62 in rotation process, after electromagnet 51 is powered off, the bullet of back-moving spring 62
Power rotates the snap back of buckle 3, restPoses.
The door closer-holder number of components of the present invention is few, and annexation is simple between part, with occupying little space, be easy to
The advantages of dismounting and installation.Under door normally open, engage between buckle of the invention and sliding block firmly, effectively prevent the pass of door
Close.When closing, buckle of the invention can swimmingly release slider, it is ensured that the smooth closing of door.After door is closed, buckle can be accurate
Really, rapidly automatically reset.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.
