Fig. 2 installs rear structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, vertical door closer function point analysis mechanism described in the utility model, comprising:
Central axis 3, it is overall that in cylindric, centrally the axis of axle 3 is provided with longitudinal hole,
On the axle body middle and lower part sidewall of central axis 3, be provided with steel ball hole, steel ball hole, perpendicular to longitudinal hole, is communicated with longitudinal hole, the symmetrical paired setting of described steel ball hole,
Adjusting rod 1, is installed on longitudinal hole internal upper part, is threaded with central axis 3,
Spindle 7, is installed on bottom in longitudinal hole,
The lower end head of adjusting rod 1 and spindle 7 snapping, spindle 7 can move up and down with adjusting rod 1, but does not rotate with adjusting rod 1,
Steel ball 8 is man-to-man to be located in each steel ball hole, and each steel ball 8 is separated by spindle 7,
The middle and upper part of central axis 3 external surface is provided with compression spring and axially retreats position-limit mechanism.
On the basis of technique scheme, in described longitudinal hole, be provided with annular indent jump-ring slot near upper end,
Longitudinal hole inwall below annular indent jump-ring slot is provided with screw thread and forms screwed hole section,
The below of screwed hole section is threadless circular hole portion.
Be provided with external screw thread in the middle part of the shaft of adjusting rod 1, coordinate with screwed hole section and achieve central axis 3 and be threaded with adjusting rod 1.
On the basis of technique scheme, in described annular indent jump-ring slot, be embedded with jump ring 2.The effect of jump ring 2 is: for limiting retrogressing (in figure direction be direction of retreat) the upwards position of adjusting rod 1.
On the basis of technique scheme, the epimere shaft undergauge of adjusting rod 1 forms undergauge shaft.
Other inner bore of part of the cross section of undergauge shaft and door closer is adaptive, both sockets that slide axially can transmit torsion.
On the basis of technique scheme, the hypomere shaft of adjusting rod 1 is provided with ring packing ring recess, and sealing ring 5 is located in ring packing ring recess.
On the basis of technique scheme, the lower end needle body undergauge of spindle 7 forms undergauge needle body.
On the basis of technique scheme, the total length of adjusting rod 1 and spindle 7 is greater than the length of longitudinal hole.
On the basis of technique scheme, compression spring axially retreats position-limit mechanism and comprises:
Upper limit part 4 can be jump ring, fixing back-up ring, annular retaining ring, shaft extrude salient point etc.,
Compression spring 6, is sleeved on central axis 3 external surface,
Lower limit part 9 is annular retaining ring,
The upper end of compression spring 6 and upper limit part 4 against,
The lower end of compression spring 6 and lower limit part 9 against.
Vertical door closer function point analysis mechanism described in the utility model, when each steel ball 8 is separated by the bigger diameter end of spindle 7, the partial sphere of steel ball 8 is exposed to outside steel ball hole, be exposed to the surface of central axis 3, lower limit part 9 is stopped by the partial sphere of steel ball 8, cannot axially-movable downwards, then the compression spring 6 of accumulation of energy can not release pressure downwards, cannot drive other mechanisms, therefore vertical door closer or hydraulic hinge door closer can freely be opened;
When user's turn adjusting rod 1 in a spiral manner, make adjusting rod 1 centrally the internal thread of axle 3 endoporus add do rotation and axially upwardly move, the spindle 7 snapped onto on adjusting rod 1 is followed adjusting rod 1 and is axially upwardly moved, only transmit both adjusting rod 1 and the snapping effect of spindle 7 make and move axially, do not transmit rotation, it is easier that object is that spindle 7 moves axially, then the undergauge needle body at the needle body place, lower end of spindle 7 is between each steel ball 8, steel ball 8 retraction steel ball hole, lower limit part 9 is no longer stopped by steel ball 8, can axially-movable downwards, promote lower limit part 9 discharge the effect of elastic force at compression spring 6 under thus drive other mechanisms, parts realize automatic door-closing function,
The change of the longitudinal degree of depth of undergauge needle body, with other mechanisms, the adjustable oil return line gap length of part fits thus realize closing speed adjustment.Adjustment door closing force and door closing speed can complete in same one end.
The content be not described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
