Preferably, described support is class step bar shaped section bar, and such step bar shaped section bar is two stage rank.
Preferential, described support high-order table top is provided with strip groove, and described expansion link is arranged in strip groove, and described electromagnet is arranged on support low order table top.
Preferential, described transmission mechanism includes card, and one end of described card is connected with the core ends of electromagnet, the other end of card on support, described support is also provided with the spacing catch of control card range of movement by hinge.
Preferential, described pivoted arm includes principal arm and forearm, and this forearm also includes segmented sleeve pipe, the external screw thread adjustment connecting rod be provided with in described segmented sleeve pipe.
Preferential, described rack inner wall is provided with travel switch, and the trip switch is connected with described power module.
The utility model possesses following advantage:
1. outward appearance housing adopts all steel material.On case panel, reserved adjusting hole, can adjust door closer closing forces and buffer speed, also has power supply, door open and-shut mode indicator lamp and machinery, electrical reset button, people can manually electrically, mechanical return or release;
2. main executing agency is the door closer main body adopting market standard, can according to actual operation requirements, and arbitrarily its specification of adjustment is replaced, to meet onsite application requirement;
3. electromagnetic tripping apparatus compares closely with door closer body combination, needs certain quality of fit, just can thread off smoothly, and the power of that is energy storage must be greater than the frictional force of gear and very heavy occlusion, needs accurate calculating and practical proof;
4. power module selects the electric elements of contactless low-power consumption to make, and has the functions such as power supply, the instruction of door open and-shut mode, delay cut-off, feedback signal; And within whole power module stand-by power consumption accomplishes 3mA milliampere, power consumption is down to minimum, energy-conservation environmental protection, eliminate large power supply power supply link, only need amplify node capacity and just so that large-scale control system exploitation and use, the energy consumption that system is unnecessary in working order can be greatly reduced; Reduce building costs simultaneously.

Description of reference numerals: 1 door closer main body, 2 springs, 3 levers, 4 cards, 5 expansion links, 6 travel switches, 7 base plates, 8 spacing catch, 9 power modules, 10 supports, 11 electromagnet, 12 fixed mounts, 13 spindle noses, 14 location are very heavy, 15 gears, 16 strip grooves, 17 principal arms, 18 forearms, 19 external screw thread adjustment connecting rods, 20 fire-fighting controllers, 21 junction boxes, 22 upper door frames, 23 labeled doors.
The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claims.
Detailed description of the invention
As Figure 1-4, the utility model includes door closer main body 1 and pivoted arm, and this pivoted arm includes principal arm 17 and forearm 18, and this forearm also includes segmented sleeve pipe, the external screw thread adjustment connecting rod 19 be provided with in described segmented sleeve pipe.The base plate 7 of described door closer main body 1 juxtaposed position is also provided with trip gear, this trip gear includes support 10, electromagnet 11 and is set with the expansion link 5 of spring 2, described support 10 is class step bar shaped section bar, and such step bar shaped section bar is two stage rank.Described support 10 high-order table top is provided with strip groove 16, because spring 2 external diameter of expansion link 5 outside suit is larger, the preset mouth of spring is had on the downside of the installation site of spring 2, so just make strip groove 16 at spring 2 two ends subsection setup, be arranged in strip groove 16 at expansion link described in spring 5, the position that described expansion link 5 upper surface is corresponding with card is provided with lever 3, and this lever 3 is the drive disk assemblies driving expansion link 5 to move according to the motion of card 4.Described electromagnet 11 is arranged on support 10 low order table top by fixed mount 12.
Transmission mechanism is connected with between the core ends of this electromagnet 11 and expansion link 5, this transmission mechanism includes card 4, one end of described card 4 is connected with the core ends of electromagnet 11, the other end of card 4 passes through hinge over the mount 10, described support 10 is also provided with the spacing catch 8 of control card 4 range of movement, this spacing catch 8 is L-type workpiece, its stationary plane is provided with fixing hole, be connected with the location very heavy 14 of door closer main body 1 near expansion link 5 end of described door closer master 1, this location very heavy 14 gear 15 coaxial with spindle nose 13 is connected; Coil on described electromagnet 11 is connected with the power module 9 be arranged on support 10 lower raft 7.
Described support 10 inwall is provided with travel switch 6, and the trip switch 6 is connected with described power module 9.
During use, as shown in Figure 5, door closer main body 1 is fixed on the upper door frame 22 of labeled door 23 by base plate 7, and one end of described pivoted arm is connected with the spindle nose 13 of door closer main body 1 and is controlled by door closer main body 1, and the other end of described pivoted arm is fixed on labeled door 23; Travel switch 6 is connected with fire-fighting controller 20 by junction box 21.
Operating principle: reset mode can make labeled door 23 keep normally open at 0-90 degree, trip gear Compress Spring 2 energy storage during reset mode, is blocked the gear 15 of door closer axle head simultaneously, realize labeled door 23 like this and locate by location very heavy 14; When fire-fighting controller 20 is cut off the electricity supply, power module 9 powers to instantaneously electromagnet 11, electromagnet 11 drives and draws expansion link 5 action, trip gear action is made to complete release, the spring 2 of energy storage promotes very heavy 14 connecting rods in location and departs from shaft end gear 15, such door closer cuts out labeled door 23, and provides and feed back signal to fire-fighting controller 20.
In sum, the purpose of this utility model is achieved.
