Abstract
The utility model provides an adjusting type door closing device, comprising a straight rod. The straight rod is sheathed with a spring, the back end of the straight rod is fixed with a leather bowl which is sheathed with an air cylinder, the front end of the straight rod is connected with a crank arm by a pin shaft, the front end of the air cylinder is connected with a pushing arm whose inner part is provided with a slide way, both ends of the pin shaft used for connecting the straight rod and the crank arm are clamped in the slide way, and the back part of the air cylinder is provided with a base which is provided with a valve. The utility model has the advantages of reasonable design and simple structure. When a door is closed, the utility model not only can avoid the friction and the collision of the edge of the door, but also can cause the door to be gently closed without noise and freely fix the door at any angle.

Description
The utility model relates to a kind of door headstock gear, specifically a kind of adjustable type door closer.
In the daily life, the door closer kind is a lot, and common door closer is to be made of a simple straight spring or leather strap, and this door closer after door is opened, cuts out door by the retractility of spring or leather strap again.It is simple in structure, but not attractive in appearance, and often mill can cause damage to door by the door angle, and when wind was big, the speed of closing the door was fast, can send the sound that makes the popular feeling frightened.Also have some door closers, though specious, complex structure, the cost height, it is very not convenient to use.Disclose a kind of positioning door closer as patent CN2166199Y, it is a kind of door check of regulating the aperture size of opening the door.The masterpiece that is applied to when opening the door on the cluster spring is used on the tooth bar, makes the tooth bar motion, drives the gear that is engaged on the tooth bar and rotates, and drives the twisting connecting rod that is fixed on the gear shaft simultaneously and also rotates, and by linkage door is closed automatically.
The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned prior art, provides a kind of rational in infrastructure, simple, easy to install, the adjustable type door closer that cost is low.
For achieving the above object, a kind of adjustable type door closer comprises straight-bar, sheathed spring on the straight-bar, the rear end of straight-bar is leather cup fixedly, sheathed inflator on it, the front end that it is characterized in that straight-bar is cranked arm by bearing pin connection one, and the front threads of gas letter connects a push arm, and push arm is in the form of slot, its preceding end closure, block is established in the rear end, and the two side is provided with slideway in its groove, connects straight-bar and is sticked in the slideway with the bearing pin two ends of cranking arm, base is equipped with at the rear portion of inflator, and base is provided with valve.
The utility model owing to be provided with is cranked arm, and has avoided the frictional impact of door with doorframe, has guaranteed the excellent of door limit, adopts inflator to make and closes automatically, not only gently but also do not have sound, and can arbitrarily door be fixed on any one angle.
Below in conjunction with accompanying drawing the utility model is done explanation in further detail:
Fig. 1 is the utility model door closure state structural representation, and Fig. 2 is the utility model door opening state structural representation, and Fig. 3 is the utility model structure vertical view.Fig. 1, Fig. 2, Fig. 3 are the embodiment schematic diagram.
From Fig. 1, Fig. 2, Fig. 3 as can be seen, a kind of adjustable type door closer of the utility model, it is provided with and cranks arm 1, straight-bar 2, spring 3, inflator 4, block 5, push arm 6, base 7, valve 8, pilot pin 9 etc.Wherein cranking arm 1 is the bow type, and the rear end connects straight-bar 2 by bearing pin, and its front end is movably connected on the doorframe during use, and 1 joint that is installed on door and doorframe of cranking arm in the process of opening door, has been avoided the collision with doorframe, the shutter limit.Sheathed spring 3 on the straight-bar 2, straight-bar 2 is arranged in push arm 6 with 1 end that is hinged by active pin shaft of cranking arm, and push arm 6 is in the form of slot, its preceding end closure, block 5 is established in the rear end, and the two side is provided with slideway 10 in its groove, the two ends of active pin shaft put in the slideway respectively, planchet and leather cup are equipped with in the rear end of straight-bar 2, and fix with nut, put inflator 4 again, the front threads of gas letter 4 connects push arm 6, rear portion dress inflator base 7 is established air valve in it, establish valve on it.The block 5 of inboard, push arm 6 rear portion, it is push and block spring 3 in the motion process of push arm 6, establishes pilot pin 9 on the block 5, and it can arbitrarily be fixed on a certain angle with door.
During use the utility model one end is fixed on the doorframe, the other end is fixed on the door, and when door was opened, inflator drove push arm compression spring and outwards moves, and air enters the inflator rear portion from valve.When leaning on the elastic force of spring again with the push arm forced back at closing time, air is compressed in the inflator, discharges by valve more lentamente then, and door is shut automatically, can before door is shut, be subjected to resistance in a flash again and slow down movement velocity, thereby door is shut gently and voicelessly.
The utility model is reasonable in design, and is simple in structure, can avoid the friction on a limit at closing time and collide mild silent when door is closed, and also can arbitrarily door be fixed in any one angle, is suitable for multiple occasion such as resident family, hotel, restaurant and uses.
