The stud bolt is connected to low locking mechanism in the lower end, the upper locking mechanism in the upper end, and positioning part in the middle part. When the door closer with the auxiliary arm positioned automatic temperature controlled fireproof closing device is installed to door, the door may be opened stably in any required angle normally and may be closed timely in case of fire.
Description
Technical field
The present invention relates to a kind of fire-proof auxiliary arm positioned automatic temperature control closing device of door closer.
Background technology
The door closer of Xiao Shouing all is not equipped with fire-proof auxiliary arm positioned automatic temperature control closing device of door closer in the market, these existing door closers generally comprise and close controlling device for doors, principal arm, piston mechanism, auxiliary, closing controlling device for doors is fixed on door or the doorframe, closing controlling device for doors is connected with principal arm, principal arm is connected with an end of piston mechanism, the other end of piston mechanism is connected with auxiliary, the other end of auxiliary is connected with door or doorframe, this door closer mostly is normally closed door closer, mainly be installed on the labeled door of throughout the year closing, at any time keep labeled door to be in closed condition, fire is by the labeled door rapid spread when preventing fire, this door closer is more suitable on the little labeled door of stream of people's throughput, but this door closer often can't reach instructions for use in the bigger public building of the stream of people of labeled door or logistics capacity, because the logistics or the stream of people need frequently pass through labeled door, people will take much time and the frequent labeled door of opening of muscle power, influenced the facility that people pass through greatly, if labeled door is fixed on the state of unlatching with instrument, labeled door will perform practically no function so, because labeled door is in opening, fire will spread by labeled door rapidly towards periphery when fire took place.
Summary of the invention
Technical problem to be solved by this invention provides a kind of fire-proof auxiliary arm positioned automatic temperature control closing device of door closer, after door closer equipped therewith is installed on the door, can make door can either open certain angle for a long time, can when fire takes place, in time close again.
For this reason, fire-proof auxiliary arm positioned automatic temperature control closing device of door closer of the present invention comprises armed lever, junction plate, stud, bearing, clamp, claw, spring and fusing insurance, the armed lever front end is rotatably connected to junction plate, junction plate is provided with the screens hole, stud passes the screens hole, the lower end of stud has retaining mechanism down, the upper end of stud has retaining mechanism, the middle part of stud has screens portion, screens portion is in the screens hole, junction plate is sandwiched between retaining mechanism and the following retaining mechanism, when rotating, junction plate can drive stud, last retaining mechanism and following retaining mechanism rotate, the upper end of last retaining mechanism is fixed with clamp, also be with bearing on the last retaining mechanism, at least be rotatably connected to two claws on the bearing, wherein the leading portion latch spoon of at least two claws connects by the fusing insurance, the fusing insurance at high temperature can fuse, the connection of fusing insurance impels two claws to close up mutually and tightens clamp, stud when two claws do not clamp clamp, last retaining mechanism can rotate relative to bearing with clamp.
Because the armed lever of fire-proof auxiliary arm positioned automatic temperature control closing device of door closer of the present invention is connected with junction plate, junction plate rotates the last retaining mechanism and the rotation of following retaining mechanism that can drive stud and two ends thereof when armed lever rotates, be fixed with clamp and go up on the retaining mechanism, when two claws on being rotatably connected on bearing do not block clamp, armed lever can freely rotate, and door leaf is always fastened by the effect of door closer; When two claws block clamp, because last retaining mechanism and clamp interfix, at this moment clamp, last locking Agency And hook bolt all can't rotate, and then armed lever also can't be rotated, if the user opens certain angle to door leaf again with two claws chucking clamp, at this moment door leaf just can be positioned at the opening angle of setting, because the latch spoon of two claws is connected by the fusing insurance, the fusing insurance can be fused by temperatures involved voluntarily when fire takes place, at this moment claw unclamps the chucking to clamp, stud can freely rotate, and door leaf can cut out by the effect of door closer at once.
Above-mentioned fire-proof auxiliary arm positioned automatic temperature control closing device of door closer can also be done following improvement: wherein descending retaining mechanism can be locking nut, last retaining mechanism can be a circle cover inner nut, bearing is enclosed within on the circle cover inner nut, locking nut and circle cover inner nut respectively with having of stud two externally threaded connecting portion be threaded.Because two of stud is connected with locking nut and circle cover inner nut, the circle cover inner nut of the fire-proof auxiliary arm positioned automatic temperature control closing device of door closer of this structure is to be threaded with stud, therefore circle cover inner nut can compress junction plate when door leaf rotates towards the direction of cutting out, because the another side of junction plate has locking nut, door leaf can be positioned at the enable possition of setting, when door leaf circle cover inner nut when the direction of opening is rotated relatively rotates with stud and separates along screw thread is reverse, door leaf still can forward bigger angle to from the opening angle of setting, the installation and the replacing of the parts of the convenient product of this in addition structure make things convenient for production and processing.
