In the present embodiment, the mandrel 4 includes a fixing member 41 positioned in the second seat tube 221 of the second sheet 22 and rotating in synchronization with the second sheet 22, and is placed in the kit unit 6 A shaft segment 43, and a shaft segment 44. It should be noted that the distal acting member 63 is located between the hydraulic cylinder 621 and the shaft segment 43. And the proximal action member 64 is disposed between the shaft segment 43 and the fixing member 41.

The fixing member 41 has a bolt hole 411 and a groove 412 disposed along the axis X direction, and two grooves 413 formed on opposite sides of the axis X direction. In this embodiment, the groove 412 is a circular groove.

The shaft segment 43 passes through the through hole 642 and has a stud 431 which is coupled with the square bolt hole 411 of the fixing member 41, opposite to the stud 431 and for the top pin 622 and the elastic member 623.

The second sheet 22, at a preset angle (such as 80-90 degrees), produces an effect of rubbing the stop at the highest point of the rubbing surface 732, whereby the door leaf can be temporarily stopped at a preset angular position, and By gently pulling or nudging the door leaf, the door leaf can be automatically closed, and the closing speed of the preset angle can be controlled, for example, below 20 degrees, or 20-60 when the first sheet 21 or the second sheet 22 is closed. In the case of the friction surface 732, the frictional resistance is generated, and the door closing speed of the door leaf is changed. It is worth noting that the angle at which the door leaf temporarily stops rotating when the door is closed or the door closing speed is changed can be matched with the curvature position of the friction surface 732 of different friction members 73, and can be arbitrarily selected from 180 degrees to 80 degrees according to customer requirements. Change, when not limited to this.

The collars 5 are disposed between the tube member 31 of the kit unit 3 and the second seat tube 221 and block the first seat tube 211 and the second seat tube 221 . The collar 5 may be a polyoxymethylene (POM) or a polytetrafluoroethylene (PTFE) for lifting the first seat tube 211, the second seat tube 221 and the kit unit 6, 7 The degree of lubrication between the pipe fittings 61, 71, and the reduction of resistance and wear.

When the objects 11 and 12 are joined, the first reference surface 213 of the first sheet 21 or the second reference surface 223 of the second sheet 22 is pressed against the edge 111 of the object 11, or The edge 121 of the object 12 can be arranged such that the plurality of hinge devices can be aligned in a vertical direction and a parallel direction with respect to the object 11 or the object 12, thereby avoiding the positions of the hinge devices in the vertical direction and the parallel direction during installation. The upper error can improve the smoothness of the door leaf rotation.

Referring to FIG. 1 and FIG. 5 and FIG. 6, when the external force drives the first sheet 21 to rotate around the axis X to open the door, the first sheet 21 synchronously drives the kits through the first seat tubes 211. Tubes 61, 71 of units 6, 7. At this time, since the fitting blocks 632 of the distal end member 63 are installed in the first fitting groove 6112 of the first pipe segment 611 and the second fitting groove 6123 of the second pipe segment 612, when the first When the flap 21 rotates, the tubular member 61 synchronously drives the distal end active member 63, the proximal end acting member 64 to rotate, and the second seat tube 221 of the second sheet 22 and the fixing member 41, the shaft segment When the tube member 61 is not rotated, the tube member 61 and the distal end member 63 and the proximal end member 64 are urged by the proximal inclined surface 641 against the proximal end of the shaft portion 43 during the rotation. 434, and widening the distance between the shaft segment 43 and the proximal end member 64, and pushing the shaft portion 43 to move up and down linearly toward the distal end member 63, and the distal end slope 631 is matched with the distal end. The face 4331 is engaged, and the distance between the shaft segment 43 and the distal end member 63 is reduced, so that the shaft segment 43 pushes the top pin 622 to press and contract the valve ejector pin 6213 of the hydraulic cylinder 621 to control the speed of closing the door. The elastic member 623 is compressed by the pressing surface 432 to generate a force that interlocks with each other.

At the same time, the pipe member 71 will synchronously drive the friction member 73 to rotate, and also the friction member 73 and the shaft segment in the case where the second seat tube 221 of the second sheet 22 and the fixing member 41 are not rotated. The convex portion 422 of the 42 is frictionally contacted during the rotation to generate a triggering force against the aforementioned external force.

When the external force is released, the elastic member 623 is pressed by an external force when the door is closed, and can provide an elastic restoring force when the door is opened, so that the tubular member 61 of the kit unit 6, the distal acting member 63, and the proximal end act. a member 64, the tube member 71 of the kit unit 7, the friction member 73 and the first sheet 21 are reversely rotated, and the distal end member 63 is pushed by the distal slope 631 to the distal end of the shaft segment 43. The face 4331 expands the distance between the distal end member 63 and the shaft segment 43. The proximal end member 64 engages with the proximal end face 434 of the shaft segment 43 to reduce the proximal end effect. When the distance between the member 64 and the shaft portion 43 is displaced, the shaft portion 43 is displaced toward the proximal end member 64, and the ejector pin 6213 of the hydraulic cylinder 621 is no longer forced against the top pin 622 to release the elastic member 623. The compressive force with the ejector pin 6213 of the hydraulic cylinder 621.

It should be noted that even if the triggering force of the elastic member 623 is insufficient, during the forward and reverse rotation of the inclined surface 631 of the distal end member 63, the surface 4331 can be matched with the distal end of the shaft segment 43. The engaging relationship acts to push the distal slope 631 of the distal action member 63 to assist the forward and reverse rotation of the distal action member 63 to enlarge the distance between the distal end member 63 and the shaft segment 43. And narrowing the spacing between the proximal bevel 641 of the proximal member 64 and the proximal abutment surface 434 of the shaft segment 43.

Since the hinge device of the present invention has no directional restriction during installation, when the external force drives the second sheet 22 to rotate around the axis X to open the door, the second sheet 22 passes through the second seat tube. The fixing member 41 of the spindle 4 is synchronously driven to make the fixing relationship of the fixing member 41 through the bolt hole 411 of the fixing member 41 and the bolt 431 of the shaft segment 43 during the rotation, and the grooves The engagement relationship between the slot 413 and the pegs 441 of the shaft segment 44, and the engagement relationship between the pegs 431 of the shaft segment 43 and the pin holes 440 of the shaft segment 44 simultaneously drive the shaft segment 43, the shaft segment 44 rotation.

Thereby, the convex portion 442 of the shaft segment 44 is frictionally contacted with the friction member 73 to generate a triggering force against the external force, and the speed of closing the door is controlled by the strength of the triggering force.

At the same time, the proximal end engaging surface 434 of the shaft segment 43 is urged against the proximal bevel 641 of the proximal end member 64, since the proximal end member 64 is secured within the groove 6122 of the second tube segment 612 of the tubular member 61. The distance between the shaft segment 43 and the proximal end member 64 is increased, and the shaft segment 43 is pushed up and down in a direction of the distal end member 63, and the distal end surface 631 is matched with the distal end surface. 4331 is engaged, and the distance between the shaft segment 43 and the distal end member 63 is reduced, so that the shaft segment 43 pushes the top pin 622 to press the ejector pin 6213 of the hydraulic cylinder 621, and the urging surface 432 compresses the ejector pin 432. When the elastic member 623 narrows the spacing, when the ejector pin 6213 of the hydraulic cylinder 621 is contracted to generate resistance (ie, the triggering force), the speed of closing the door is slowed down, and when the door is closed to less than the preset angle (for example, less than 20 degrees), all The cushioning resistance disappears.

Thereby, when the external force is released to close the door, the second sheet 22 will drive the shaft segment 43 and the shaft segment 44 to rotate in the opposite direction. The tube member 61 of the kit unit 6, the distal end member 63, the proximal end The action member 64, the tube member 71 of the kit unit 7, the friction member 73 and the first sheet 21 are not rotated, so that the shaft portion 43 is pushed by the distal end engagement surface 4331 during the rotation process. The distal end slope 631 of the distal end member 63 is topped, and the distance between the distal end effect member 63 and the shaft portion 43 is enlarged by the return elastic force of the spring 623, and the proximal end engagement surface 434 is adjacent thereto. The end effect member 64 is engaged to reduce the distance between the proximal end member 64 and the shaft portion 43 while being displaced toward the proximal end member 64 and no longer abut against the top pin 622 to release the elastic member 623. The compressive force with the ejector pin 6213 of the hydraulic cylinder 621.

It should be noted that the hexagonal setting hole 6211 of the hydraulic cylinder 621 can be embedded by a hand tool, whereby the hydraulic cylinder 621 can be adjusted by the hand tool to adjust the screwing of the hydraulic cylinder 621 and the pipe member 61. The depth of the depth is adjusted to adjust the tightness of the position of the ejector pin 6213 of the hydraulic cylinder 621 in contact with the top pin 622 to move the buffer position, thereby adjusting the angular range of the oil pressure buffer region for the door leaf closing speed reduction. The hexagonal orifice 6212 can be inserted into the other hand tool, whereby the flow rate of the oil pressure inside the hydraulic cylinder 621 is adjusted by the hand tool, thereby controlling the speed at which the door leaf closes, and the screw can also be screwed or screwed back. The end piece 74, and the triggering force of the reed 721 is changed by the pad 722, or the friction member 73 of the different friction surface 732 is replaced, and the friction surface 732 of the friction member 73 and the convex portion of the shaft segment 44 can be made. The 442 produces frictional resistance at different angles and is capable of adjusting the amount of friction to form another way to mechanically control the closing speed.

In addition, it should be noted that, in addition to the additive effect of the present embodiment, the first gap D1 of the end coil 323 of the torsion spring 32 can be smaller than the second gap D2 of the intermediate coil 324. The special design is to further increase the torsion force without changing the overall length of the torsion spring 32. For example, the end coil 323 of each torsion spring 32 is a three-turn tight coil. For example, each of the torsion springs with the same clearance has one rotation. The scale can generate a trigger force of 15Kg (return torque), and a torsion spring 32 of the present invention can generate a triggering force (recovering torque) of 15*3=45kg per rotation of one scale, thereby passing through the hexagonal hole 331 When the end piece 33 drives the torsion spring 32 to rotate by one scale, for example, when the scale 1 is rotated to the scale 2, the torsion spring 32 of the present invention can generate a triggering force (recovering torque) of 15*3*2=90Kg. When the scale 2 is rotated to the scale 3, the torsion spring 32 of the present invention can generate a triggering force (recovering torque) of 15*3*3=135Kg, and when the scale 3 is rotated to the scale 4, the torsion spring 32 of the present invention can generate 15 *3*4=180Kg Trigger force (torque replies). Thereby, a 300Kg heavy door originally required three hinge devices to be pushed, and the present invention can be pushed only by a second embodiment (180Kg*2=360Kg).

Since the hinge device of the present invention has no directional restriction during installation, when the external force drives the second sheet 22 to rotate around the axis X to open the door, the second sheet 22 passes through the second seat tube. 221 synchronously driving the fixing member 41 of the spindle 4, so that the fixing member 41 synchronously drives the shaft segments 42 to twist the end portions 322 of the torsion springs 32 during the rotation, in the first page 21 When one of the tubes 211 and the end piece 33 are fixed to the end portions 321 of the torsion springs 32, the end coils 323 and the intermediate coils 324 of the torsion springs 32 can be rotated in the accumulating direction. And generate a trigger force that resists the aforementioned external force and can be stored.

Thereby, when the external force is released and the door is closed, the torsion springs 32 release the triggering force, and when the door is closed, an added returning torque can be provided, so that the tube member 31 of the kit unit 3 and the first sheet are 21 reverse rotation.

It should be noted that since the first gap D1 of the three tight end coils 323 of the torsion springs 32 is smaller than the second gap D2 of the intermediate coils 324, the torsion springs 32 can make the expected torque value multiples. Increase, and increase the trigger force (recover torque).

In addition, the end pieces 33 of the kit units 3 are rotated by a tool (not shown) so that the end pieces 33 twist the torsion springs 32 to a predetermined angle to increase or decrease the lengths. The torsion force of the torsion spring 32 reaches the purpose of controlling the closing force, thereby improving the smoothness when closing the door.

For the action and function of the kit unit 7, refer to paragraph [0029] and paragraph [0033].

When the external force is released, the torsion spring 32 of the kit unit 3 also releases the aforementioned triggering force, and can provide a returning torque when the door is closed, so that the tube member 31 of the kit unit 3, the tube member 71 of the kit unit 7, the friction The piece 73 rotates in the opposite direction to the first sheet 21. Since the general knowledge in the art can infer the details of the expansion based on the above description, it will not be explained.
