Detailed description of the invention
Embodiment 1: as Figure 1-3, a kind of built-in floor spring, comprising: housing 11, main shaft 1, main cam 2, combinaing valve body 4; Be provided with the different orthogonal axis hole of two length in housing 11, major axis is provided with groove in hole, and both sides external is provided with to be convenient to install fixing chimb, and end is curved or square; Main shaft 1 is loaded in the minor axis hole of housing 11 by bearing 3 and is connected with main cam 2, and the shape of main cam 2 is 8-shaped, and curved surface is provided with groove; In major axis hole, sequence unit has combinaing valve body 4, spring 5, end cap 10; The end of described combinaing valve body 4 is provided with the guiding parts engaged with main cam 2, and inside is provided with one way valve 6, flow speed control valve 7, and external surface is provided with oil sealing and wear ring; Be full of resisting medium in housing, axis hole end is equipped with end cover.Because housing adopts thin-wall section, end is designed to arc and the optimum organization of 8-shaped cam, and make the distance of spindle axis and doorframe the shortest, door leaf can realize seamless rotation, and the generation of security incident is stopped in transmission.When opening rear and doorframe use, housing 11 is screwed in door leaf lower frame by chimb, main shaft 1 is hinged with the Connection Block in doorframe, when external force promotes door leaf rotation, door leaf drives housing 11 to rotate along opening direction together, main shaft 1, main cam 2 are motionless, the inevitable 8-shaped curved surface along main cam 2 slides and rotates the auxiliary cam 14 (this example is that cam-engaged is secondary) of combinaing valve body 4 end, and promotion combinaing valve body 4 moves Compress Spring 5, storage power simultaneously.When door leaf rotates 90 degree of positions, auxiliary cam 14 is in the top arc positioning groove 15 li of main cam 2 curved surface, under the effect of spring 5 pressure, stop at 90 degree of opening positions, (rotating successively can respectively 180 degree, 270 degree stopping, until be turned back to 360 degree of original positions) make door leaf be in stable state; In the circle distribution of curved surface, angle shared by locating slot 15 is very little, as long as door leaf is turned an angle in the other direction a little along opening the door, auxiliary cam 14 is in curved surface and mutually slides engagement after crossing arc positioning groove 15, because spring 5 releases energy, the pressure of spring 5 is decomposed into the active force rotated along curved surface circumferencial direction, drives door leaf automatically to rotate, until door leaf cuts out completely towards direction of closing the door.Particularly adopt thin-wall section, the scientific optimization of the quincunx cam of curved and small-sized 8 word of shell end, built-in combinaing valve body combines, not only solve the defect of conventional art, little wheelbase design thoroughly can also stop the generation of security incident, reduce school, unit, family, public place are surprisingly discord hidden danger, greatly can improve the use standard of existing gating technology.The speed of door closing speed is regulated (this example is outer adjustment) by flywheel 8, flow speed control valve 7, and end cap 10 is provided with pressure maintaining valve 9 or safety valve changes to adapt to varying environment, ensures safety.
Embodiment 2: as illustrated in figures 4-5, the guiding parts of combinaing valve body 4 end is that roller 12 forms rolling surface Meshing Pair with main cam 2.
Embodiment 3: as shown in fig. 6-7, the guiding parts of combinaing valve body 4 end is that spin 13 forms rolling wire face Meshing Pair with main cam 2.
Embodiment 4: as Figure 8-9, the guiding parts of combinaing valve body 4 end is that auxiliary cam 14 forms slip Meshing Pair with main cam 2.
Protection scope of the present invention is not limited to the present embodiment, and when not departing from the present invention's design, the distortion of any technical characteristic carried out and equivalent transformation, all belong to scope.
