Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the sectional view of a kind of liquid vibration damping equipment of the present invention preferred embodiment;
Fig. 2 is the structure broken away view of a kind of liquid vibration damping equipment of the present invention preferred embodiment.
Embodiment
As shown in Figure 1, in a preferred embodiment of the invention, this liquid vibration damping equipment comprises vibration damping equipment and directional post 200.Wherein, vibration damping equipment comprises damper cylinder 100 and a plurality of damping device 300 that fills vibration damping liquid.As can be seen from Figure 1, one end opening of damper cylinder 100, the lower end of directional post 200 is stretched into and vibration damping liquid is sealed up for safekeeping in damper cylinder 100 from the opening end of damper cylinder 100, damping device 300 is evenly distributed on the damper cylinder 100, one end and damper cylinder 100 are fixing, and the other end is held in the lower end of directional post 200.
It should be noted that between directional post 200 and the damper cylinder 100 not have direct annexation, because if between directional post 200 and the damper cylinder 100 for being rigidly connected, can directly reduce so the effectiveness in vibration suppression of this device.Heating electronic component is the upper end that is fixed on directional post 200, in use, whole vibration damping equipment need to be fixed in the electrical equipment rigid objects, owing in the damper cylinder 100 the damping fluid body being housed, when vibration damping equipment is subject to fierce vibration, most vibrational energy is all by the vibration damping liquid absorption in the damper cylinder 100, and damping device 300 can further play the effect of buffer shock-absorbing, thereby reaches good effectiveness in vibration suppression.
Further, the lower end of directional post 200 is hemisphere.Then directional post 200 hemispheric lower ends can absorb by vibration damping liquid fully with focusing on a bit from from all directions vibration source, can significantly improve the effectiveness in vibration suppression of device, and the heating electronic component that can conveniently be fixed on directional post 200 upper ends realizes 360 ° rotation.Understandable, the diameter of directional post 200 hemisphere lower ends should equate with the internal diameter of damper cylinder 100.
As shown in Figure 2, preferably, offer circular groove 202 along the outer wall of directional post 200 hemisphere lower ends, be provided with the seal ring 203 for sealing vibration damping liquid in the circular groove 202.By sealing circle 203, directional post 200 can be sealed vibration damping liquid up for safekeeping in damper cylinder 100 well, prevents oozing out of vibration damping liquid.
In a preferred embodiment of the invention, above-mentioned damping device 300 comprises fixing part 301, the cylindrical portion 302 from fixing part 301 Surface Verticals to the hollow of downward-extension, is located at the buffer element 303 in the cylindrical portion 302 and the stop hoodle 304 of being located at buffer element 303 1 ends.This damping device 300 is fixed in the edge of the opening end of damper cylinder 100 by fixing part 301, have through hole on the fixing part 301, and the opening side edge of damper cylinder 100 is provided with corresponding tapped hole, and both fix by screw.And the bottom opening of cylindrical portion 302, buffer element 303 is located in the cylindrical portion 302, one end contacts with the upper surface of cylindrical portion 302 inner chambers, the other end is provided with stop hoodle 304, and understandable, buffer element 303 should be compressed, and stop hoodle 304 divides the opening that exposes to cylindrical portion 302 and contacts with the upper surface of directional post 200 hemisphere lower ends in the restoring force effect bottom of buffer element 303.Like this, remaining vibration will be passed in the buffer element 303 by stop hoodle 304 and be cushioned, and further strengthens effectiveness in vibration suppression.Understandable, the diameter of cylindrical portion 302 bottom openings should be less than the diameter of stop hoodle 304.Preferably, buffer element 303 can adopt spring.
In a preferred embodiment of the invention, vibration damping liquid is high temperature resistant, high pressure resistant, explosion-proof and anti-flaming liquid, preferably can adopt high pressure oil.
Further, the upper end of directional post 200 is for being used for the fixedly fixed pan 201 of heater element.In a preferred embodiment of the invention, heater element is bulb, and bulb is fixed on the fixed pan 201 by socket, and the pin of bulb is inserted in the interior also with it electrical connection of pin holes of socket.Be reserved with through hole on the socket, be provided with corresponding tapped hole at fixed pan 201, both are fixedly connected with by screw.
Above embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and accordingly enforcement, can not limit protection scope of the present invention.All equalizations of doing with claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
