Abstract
The invention discloses a door control gas spring comprising a front connecting lug, a rear connecting lug and a gas spring body, wherein the front connecting lug and the rear connecting lug are connected with a door and a cabinet; the gas spring body is arranged between the front connecting lug and the rear connecting lug; the gas spring body comprises a front end cover component and a rear cover connecting piece in sequence; a cylinder body is arranged between the front end cover component and a rear cover, and is internally provided with a piston and a piston rod; one end of the piston rod is embedded into the piston, and the other end of the piston rod can extend out of the cylinder body freely; the end cover component comprises a guide ring, rod rings and rolling rings in sequence; and the rod rings are staggered pairwise; and the two rolling rings form two rolling lines. The door control gas spring is applied in opening and closing of a cabinet door of a cabinet (the cabinet door can be made of wood or aluminium); the largest opening angle reaches 110 degrees; and the matched force type according to the weight of a door plate can reach 150N at highest. By virtue of life prediction for 100,000 times, the movement is smooth, and phenomena such as vibration and creeping are avoided.
Description
Technical field
The present invention relates to a kind of gated devices, particularly a kind of gate air spring.
Background technology
The gate air spring; Comprise and door, the front and back lug that is connected of cabinet and the air spring body between the lug of front and back; Described air spring body comprises anterior end-cap assembly and back lid attachments successively, is provided with cylinder body between end-cap assembly and the back lid attachments, is provided with piston in the cylinder body; One end embeds piston, and the other end can freely stretch out the piston rod of cylinder body.Existing gate air spring, its end-cap assembly tightness is bad, and working pressure is little, and cylinder body adopts cold-drawn pipe, and is smooth inadequately, and wall unevenness is even, explosion easily.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art, provides that a kind of tightness is good, the gate air spring of safety, long service life.
For solving the problems of the technologies described above; Technical scheme provided by the present invention is: a kind of gate air spring comprises and door, the front and back lug that is connected of cabinet and the air spring body between the lug of front and back that described air spring body comprises anterior end-cap assembly and back lid attachments successively; Be provided with cylinder body between end-cap assembly and the back lid attachments; Be provided with piston in the cylinder body, an end embeds piston, and the other end can freely stretch out the piston rod of cylinder body; Described end-cap assembly is included as the guide collar of piston rod movement guiding successively, staggered bar portion at interval encloses and the roll extrusion circle in twos, and described two roll extrusion circles constitute twice roll extrusion line.
Further, in above-mentioned gate air spring, described roll extrusion circle is a copper band.Adopt between described piston and the piston rod and revolve riveting and be connected, described piston is the zinc-containing alloy piston.Described back lid attachments is provided with the threaded rod that is connected with the back lug, and said cylinder body adopts with the back lid attachments and is welded to connect.
Further again: above-mentioned gate air spring, described cylinder body adopt the smart pipe production technology of pricking to manufacture.
Compared with prior art, gate air spring provided by the present invention, described end-cap assembly are included as the guide collar of piston rod movement guiding successively, staggered bar portion at interval encloses and the roll extrusion circle in twos, and described two roll extrusion circles constitute twice roll extrusion line.Two roll extrusion circles add guide collar, form 3 roads guiding snare, and increase the steering capability of piston rod, make the air spring action smooth and easy.Adopt between piston and the piston rod and revolve riveting and is connected, piston material employing Zn-base alloy is processed, and its high voltage performance is better.Cylinder body adopts the smart pipe production technology production of pricking, and endoporus fineness is higher, and is smooth and easy to guarantee the air spring action; Wall thickness is even, and is high pressure resistant to guarantee; Cylinder body adopts the welding combination with the back lid attachments, and is high pressure resistant to guarantee.During assembling, in the cylinder body of back lid attachments of burn-oning, pack into piston and piston rod revolve riveting assembly, roll extrusion circle, bar portion circle, after the guide collar, and first roll extrusion twice roll extrusion line, fixedly the roll extrusion circle closes up cylinder body with special equipment afterwards again, the fixed guide circle; Between piston rod and guide collar, squeeze into gases at high pressure with special equipment more afterwards, gas pressure is decided with door-plate weight.This gate air spring is loaded onto cabinet behind the door, and the air spring piston rod is in retracted mode, and cylinder body is interior owing to increased the volume of piston rod; It is big that the cylinder internal gas pressure becomes; Cylinder inner carrier upper O-shape ring is shifted to front end, and air can be by 4 hole fast flow speed and direction piston back cavities on the piston, and piston rod can fast retractile; With pulling out the cabinet door, piston rod is released under the effect of cylinder internal gas pressure, and the piston upper O-shape ring moves backward.It is peripheral to have sealed piston, makes gas flow to back cavity by ante-chamber from pore on the piston, makes stretching out of piston rod slow in one's movements and smooth and easy.This gate air spring is applied to the folding (the cabinet door can be a timber, aluminium door) of the cabinet door of cabinet; Maximum open angle reaches 110 °, and the strength model supporting according to door-plate weight reaches as high as 150N.Infer through 100,000 life-spans, move smooth and easy, friction, creeping phenomenon.
Description of drawings
Fig. 1 is that gate air spring vertical profile structure of the present invention is shown view;
Wherein lug, 2 back lugs, 3 back lid attachments, 4 cylinder bodies, 5 pistons, 6 piston rods, 7 guide collar, 8 bar portions circle, 9 roll extrusion circles before 1.
The specific embodiment
For the ease of those skilled in the art's understanding, floor spring of the present invention is further specified below in conjunction with the accompanying drawing and the specific embodiment:
Shown in accompanying drawing 1; A kind of gate air spring comprises and door, the front and back lug 1,2 that is connected of cabinet and the air spring body between the lug of front and back, and described air spring body comprises anterior end-cap assembly and back lid attachments 3 successively; Be provided with cylinder body 4 between end-cap assembly and the back lid attachments 3; Be provided with piston 5, one ends in the cylinder body 4 and embed piston 5, the other end can freely stretch out the piston rod 6 of cylinder body; Described end-cap assembly is included as the guide collar 7 of piston rod movement guiding, staggered bar portion circle 8 and roll extrusion circle 9 at interval in twos successively, and described two roll extrusion circles 9 constitute twice roll extrusion lines.Described roll extrusion circle 9 is copper bands.Adopt between described piston 5 and the piston rod 6 and revolve riveting and be connected, described piston is the zinc-containing alloy piston.Described back lid attachments 3 is provided with the threaded rod that is connected with the back lug, and said cylinder body 4 adopts with back lid attachments 3 and is welded to connect.Described cylinder body adopts the smart pipe production technology production of pricking.
