Abstract
The utility model relates to an automatic door spring, which is mainly composed of a sealing head 1, a shell 6, a hydraulic cylinder 7, a piston 11, etc. The left end of the shell 6 is provided with the sealing head 1, the hydraulic cylinder 7 is arranged in the inner of the shell 6, the piston 11 and a piston rod 12 are arranged in the hydraulic cylinder 7, a spring 13 are sleeved with the piston rod 12, the left end of the hydraulic cylinder is provided with a valve seat 2, a valve ball 3, a spring seat 10 and a speed regulating stem 5, positioning balls 8 are arranged in the conical holes arranged on the upper and the lower parts of the middle of the hydraulic cylinder 7, the spring arranged on the positioning balls 8 are positioned by a spring clip 14, and a rubber plug 4 is arranged in the pouring oil hole arranged in the upper part of the left end of the shell 6. The automatic door spring has the advantages of simple structure, easy fabrication, low cost, and no noise.
Description
The utility model belongs to the servicing unit that control is closed the door, a kind of Automatic door spring.
At present, no matter be office space or family, the closing automatically of control gate, great majority are to adopt a door extension spring, abroad the someone has designed a kind of mechanical rocker arm closing device, its complex structure, the cost of production height, the trouble point is many, easily produces noise, and profile is attractive in appearance inadequately.Still find no and the same or analogous record of the utility model through consulting patent documentation and interrelated data.
The purpose of this utility model is, provide a kind of simple in structure, implement convenient, noiseless Automatic door spring.
The utility model is realized as follows:
Automatic door spring, mainly contain compositions such as end socket 1, shell 6, fluid cylinder 7, piston 11, the left end of shell 6 is equipped with end socket 1, fluid cylinder 7 is contained in the inside of shell 6, piston 11 and piston rod 12 are housed in fluid cylinder 7, spring 13 is enclosed within on the piston rod 12, left end at fluid cylinder 7 is equipped with valve seat 2, valve ball 3, spring base 10 and governor valve stem 5, in the taper hole of the upper and lower setting at fluid cylinder 7 middle parts, place kick 8 is housed, the spring that is contained in the place kick 8 is located with Spring Card 14, and plug 4 is housed in the oil filler point that is provided with above the left end of shell 6.The left of piston 11 is equipped with piston ring, and right-hand being provided with can make place kick 8 embed the annular groove of location.Two joint rings 9 are housed in the right-hand member end socket of shell 6.
The utility model has the advantages that, simple in structure, implement convenient, with low cost, noiselessness, be not subjected to the door deformation effect.
Accompanying drawing is a structural representation of the present utility model.
Introduce most preferred embodiment of the present utility model below in conjunction with accompanying drawing:
Automatic door spring, during enforcement, end socket 1, shell 6 and fluid cylinder 7 can adopt metal material or use the plastic material injection mo(u)lding.During assembling, spring 13 is enclosed within on the piston rod 12 and packs in the fluid cylinder 7 together with piston 11, install governor valve stem 5, spring base 10, valve ball 3 and valve seat 2 more successively, then place kick 8 and fixing spring and Spring Card 14 are contained on the outer wall of fluid cylinder 7, install end sockets 1 after packing into the fluid cylinder 7 that assembles in the shell 6, be fixed on the support on the doorframe with the connection holes of end socket 1 left end, again piston rod 12 is fixed on the doorframe, fill with hydraulic oil by the hole that plug 4 is installed, install plug 4 then.Owing to adopted totally-enclosed interior circulation hydraulic circuit, therefore can reach the purpose of closing the door automatically.Its operating principle is: when door in off position the time, piston 11 is in the left end extreme position, when opening the door, drive piston rod by door leaf and piston is moved to right and compress spring, at this moment, hydraulic oil is pushed ball valve 3 open and is entered the fluid cylinder inner chamber, after in the people enters the room, under resilient force, make spring 13 promote piston 11 and move to left, oil is in the orifice flow of speed control rod 5 bottoms is gone into cavity between housing 6 and the fluid cylinder 7, and the position of adjusting governor valve stem can reach the quick closing valve purpose of closing the door slowly.As open a need and temporarily be not related to, then when door is opened to an angle of 90 degrees, place kick 8 springs into location in the annular groove of piston just, and at closing time, only with hand is a band gently, and place kick is deviate from can close the door automatically.
