The specific embodiment

For to the purpose of this utility model, technical characterictic and effect thereof, more further understanding and understanding can be arranged, lift a preferred embodiment now, and conjunction with figs. is described in detail as follows:

See also shown in Fig. 2-5, the utility model one preferred embodiment, a kind of Floor hinge pressure regulation device is provided with a pedestal 10, and these pedestal 10 1 ends are provided with an opening 11, be provided with a lower pulling plate 12 in this opening 11, be a rectangular panel in the present embodiment, this lower pulling plate 12 is provided with an oval fluting 121, and these lower pulling plate 12 1 ends are provided with the pivot hole 122 of symmetry, this lower pulling plate 12 is provided with the last arm-tie 13 that a shape cooperates with it, the arm-tie 13 121 corresponding perforates 131 that are provided with and slot on this.

This 12,13 of upper and lower arm-tie is provided with an axostylus axostyle 14, these axostylus axostyle 14 1 ends pass fluting 121 and join with the door (not shown), the other end protrudes out in fluting 121, this axostylus axostyle 14 is provided with a cam 141 (shown in Fig. 4,5) 12,13 of upper and lower arm-ties, this cam 141 can be combined by welding, mode such as one-body molded and axostylus axostyle 14, these cam 141 both sides are provided with the edge 142 of being received the tip shape other end by arc-curved shape one end, and this cam 141 at each edge 142 not condensation place be provided with the nock 143 of an indent.

In addition, these upper and lower arm-

tie

12,13 two ends are respectively equipped with corresponding through hole 123,133, wear a roller 15 (shown in Fig. 4,5) on each through hole 123,133 respectively.

Should go up arm-tie 13 1 ends is provided with and 122 corresponding pivot holes 132, pivot hole, pull bar 16 is hubbed in the pivot hole 122,132, link together by screw-in version and upper and lower arm-

tie

12,13, be interposed in 12,13 of upper and lower arm-ties, these pull bar 16 other ends and push rod 17 are screwed, this push rod 17 and the pull bar 16 outer elastic components 20 that are arranged with, overhead is between pull bar 16 and push rod 17, it in the present embodiment spring, these push rod 17 other ends and a piston 30 are screwed, and being connected in a connecting rod 18, these connecting rod 18 other ends protrude out outside the tail-hood 19 of pedestal 10.

Please refer to Fig. 4, shown in 5, when door does not offer along cam 141 bottom surfaces that a side direction moves and when driving axostylus axostyle 14 and rotating, cam 141 can move thereupon, and make cam 141 lean position respectively at roller 15 by original two ends, the direction of rotating to door moves, simultaneously, roller 15 is also shifted at the edge 142 of cam 141 thereupon, because of the edge 142 of this cam 141 there is no any obstruction and is arc-curved shape, make the edge 142 of cam 141 can be along with the rotation of door, constantly slip over roller 15, and under the promotion of roller 15, make the cam 141 can be by the position transfer of original zero degree to certain angle, moreover, cam 141 more can be wherein nested with roller 15 by nock 143, and door is positioned on the certain angle position.

Please refer to shown in Figure 6 again, when the application of force of needs adjustment door rotation is spent, rotatable connecting rod 18, and push rod 17 is moved thereupon, and make elastic component 20 condensations or extension, and then the folding application of force degree of adjustment and axostylus axostyle 14 pivot joint doors, therefore, not only simplify part, and the assembling also save time, thereby reach simple and easy purpose.

The above embodiment only is the utility model most preferred embodiment, and all personnel that are familiar with this skill all can carry out various conversion or decoration, but all should be contained in the category that the utility model claims are defined.
