Description
Technical field
The utility model relates to the closed sound arrester of a kind of end opening, is more specifically that one is placed in door leaf, coordinates door leaf to close and realizes the device that door end opening closes sound insulation, belong to architectural decoration field.
Background technology
Door is that noise transmission arrives indoor main path, in some places relatively high to sound isolation requirement such as high-grade hotel, conference rooms, the sound that the step that guest passes by and Conversation Voice, corridor car promote, the serial noises such as cleaning carpet, usually import indoor formation noise into by gap under door, thus affect normal life.
For this reason, usually at present in door-plate bottom, one section of rubber strip is installed, the gap on sealing door-plate end opening and ground.This method can reduce noise to a certain extent and import into, but if rubber strip tension, the resistance of rubber strip and ground friction easily causes door leaf closed inconvenient; If rubber strip is excessively loose, does not then still have and close soundproof effect preferably.Meanwhile, rubber strip and ground friction are also easy to rubber strip is worn and torn.
Utility model content
For above-mentioned situation, the problem that the utility model quasi-solution is determined is to provide a kind ofly does not affect operation that door leaf closes, close that soundproof effect is good, the closed sound arrester of the door end opening that is not easy abradable seal bar.
For reaching above-mentioned purpose, the utility model by the following technical solutions: the closed sound arrester of a kind of end opening, it comprises crossbeam, push rod, adhesive tape fastener and sound insulation adhesive tape,
Described crossbeam towards door leaf open side have stretch out touch a little, described crossbeam rotates side towards door leaf and is provided with crossbeam back-moving spring, the downside of described crossbeam is provided with more than two or three arc-shaped notch, and described crossbeam to be arranged in door leaf and can door leaf transverse shifting relatively;
The upper end of described push rod is provided with spring block, the top of described spring block is provided with and spherically presses head, the lower end of described push rod is through the lower surface of door leaf, and on described push rod, also cover has adhesive tape back-moving spring, under two ends of described adhesive tape back-moving spring withstand on the spring block respectively and lower surface of door leaf; The quantity of described push rod is equal with the arc-shaped notch quantity on the downside of crossbeam, above described push rod on the spherical arc-shaped notch pressing crown correspondence on the downside of crossbeam;
Described adhesive tape fastener in the downside of door leaf, and is fixed on the lower end of push rod;
The upper end of described sound insulation adhesive tape is fixed in adhesive tape fastener.
The described spherical head that presses is rotatably connected above spring block.
Adopt such scheme, the closed sound arrester of door end opening of the present utility model, it comprises crossbeam, push rod, adhesive tape fastener and sound insulation adhesive tape, due to crossbeam towards door leaf open side have stretch out touch a little, crossbeam rotates side towards door leaf and is provided with crossbeam back-moving spring, and crossbeam to be arranged in door leaf and can door leaf transverse shifting relatively; That is, crossbeam opens the elastic force of side by door leaf all the time, but when touch a little be subject to thrust time, the elastic force that crossbeam can overcome crossbeam back-moving spring moves to door leaf rotation side.Again because the upper end of push rod is provided with spring block, the top of spring block is provided with and spherically presses head, and the lower end of push rod is through the lower surface of door leaf, and on push rod, also cover has adhesive tape back-moving spring, spherically above push rod presses on the arc-shaped notch corresponding on the downside of crossbeam of the crown.In door opening, the spherical centre pressing crown arc-shaped notch on the downside of crossbeam, when door is shut, doorframe top pressure crossbeam stretches out and touches a little in door leaf side, and the elastic force making crossbeam overcome crossbeam back-moving spring rotates side to door leaf and moves, the spherical like this centre pressing the crown and depart from arc-shaped notch in the position of crossbeam, the spherical head that presses is moved down, causes push rod to move down, make adhesive tape fastener and sound insulation adhesive tape move down equally, whole door end opening is closed by sound insulation adhesive tape, reaches soundproof effect.
On the contrary, when the door is open, doorframe depart from door leaf side touch a little, due to the elastic force effect of crossbeam back-moving spring, crossbeam to door leaf open side move, touch and a little stretch out door leaf unlatching side, the spherical centre pressing crown arc-shaped notch on the downside of crossbeam, spherical pressing on head is moved, and push rod also moves up, make adhesive tape fastener and sound insulation adhesive tape move up and down equally, make sound insulation adhesive tape remotely not affect the closed operation of door leaf in face.
Therefore, the closed sound arrester of door end opening of the present utility model, have do not affect the closed operation of door leaf, close soundproof effect good, be not easy the advantages such as wearing and tearing.
