Embodiment 1
As Figure 1-3, a kind of built-in floor spring comprises: housing 11, main shaft 1, main cam 2, combinaing valve body 4; Be provided with the different orthogonal axis holes of two length in the housing 11, major axis is provided with groove in the hole, and both sides external is provided with the chimb of being convenient to install and fix, and the end is curved or square; Main shaft 1 is packed into by bearing 3 and is connected with main cam 2 in the minor axis hole of housing 11, main cam 2 be shaped as 8 fonts, curved surface is provided with groove; Sequence unit has combinaing valve body 4, spring 5, end cap 10 in the major axis hole; The end of described combinaing valve body 4 is provided with the guiding parts with main cam 2 engagements, 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 the housing, the axis hole end is equipped with end cover.Because housing adopts thin-wall section, the end is designed to arc and 8 font cam optimum organizations, makes the distance of spindle axis and doorframe the shortest, and door leaf can be realized seamless rotation, and the generation of security incident is stopped in transmission.When opening the use of back and doorframe housing 11 is fixed in the door leaf lower frame with screw by chimb, main shaft 1 is hinged with the Connection Block in the doorframe, when external force promotes the door leaf rotation, door leaf drives housing 11 and rotates along opening direction together, main shaft 1, main cam 2 are motionless, this example of auxiliary cam 14(of combinaing valve body 4 ends is the cam-engaged pair) rotation of sliding of inevitable 8 font curved surfaces along main cam 2, and promote combinaing valve body 4 simultaneously and move compression spring 5, storage power.When door leaf rotates 90 degree positions, auxiliary cam 14 is in 15 li of the top arc positioning grooves of main cam 2 curved surfaces, under the effect of spring 5 pressure, stop at 90 degree opening positions, (rotation can stop at 180 degree, 270 degree respectively successively, spend original positions up to being turned back to 360) make door leaf be in stable state; On the circle distribution of curved surface, the shared angle of 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 crossed and is in the curved surface engagement of sliding mutually behind the arc positioning groove 15, because spring 5 releases energy, the pressure of spring 5 is decomposed into the active force that rotates along the curved surface circumferencial direction, drives door leaf and rotate towards the direction of closing the door automatically, close fully until door leaf.Particularly adopt thin-wall section, the scientific optimization combination of the quincunx cam of curved and small-sized 8 words of shell end, built-in combinaing valve body, not only solved the defective of conventional art, the generation that security incident can also be thoroughly stopped in little wheelbase design, reduce school, unit, family, the unexpected hidden danger of being discord in public place, can improve the use standard of existing gating technology greatly.The speed of the speed of closing the door is regulated (this example is regulated for outer) 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, guarantees safety.
Shown in Fig. 4-5, the guiding parts of combinaing valve body 4 ends is that roller 12 constitutes the rolling surface Meshing Pair with main cam 2.
Shown in Fig. 6-7, the guiding parts of combinaing valve body 4 ends is that spin 13 constitutes rolling wire face Meshing Pair with main cam 2.
Shown in Fig. 8-9, the guiding parts of combinaing valve body 4 ends is that auxiliary cam 14 constitutes the slip Meshing Pair with main cam 2.
Protection scope of the present invention is not limited to present embodiment, and under the situation that does not break away from the present invention's design, the distortion of any technical characterictic that carries out and equivalent transformation all belong to protection domain of the present invention.
