Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See figures.1.and.2: the fan elevation and subsidence regulating device, comprise guide pillar 1, guide pin bushing 2, adjustment module 3, tensile elements 4 and be located at the limit stoper on guide pillar 1, guide pin bushing 2 is set on guide pillar 1, tensile elements 4 is located in guide pin bushing 2 and is positioned at an end of guide pillar 1, one end of tensile elements 4 is fixedly connected with guide pin bushing 2, adjustment module 3 is arranged on guide pin bushing 2 and setting corresponding to limit stoper, and tensile elements 4 is clockwork spring.
Limit stoper comprises bounding means 51 and is located at a plurality of restraining grooves 52 on guide pillar 1, and restraining groove 52 is along the bearing of trend setting of guide pillar 1, and bounding means 51 matches with restraining groove 52.
As shown in Figure 3 and Figure 4, adjustment module 3 comprises regulates button 31, spring 32 and gland 33, regulate on button 31 and offer mounting hole 311, spring 32 1 ends are set on column 23, the other end inserts in mounting hole 311, regulating button 31 is buckled on opening 22, gland 33 is positioned at the outside of spring 32, for pressing spring 32, prevent that spring 32 from outwards ejecting, regulate button 31 setting corresponding to bounding means 51, regulate button 31 be used to compressing bounding means 51, prevent that bounding means 51 from sliding on guide pillar 1, guarantee the stability that fan uses.
As shown in Figure 6, regulate button 31 bottoms corresponding with bounding means 51, regulate button 31 bottoms and be provided with inclined-plane 312.
As shown in Figure 5, the fan elevation and subsidence regulating device also comprises fixture block 7, and fixture block 7 is hollow cylindrical, fixture block 7 is fixedly connected with an end of guide pin bushing 2, and fixture block 7 is between guide pin bushing 2 and guide pillar 1, and fixture block 7 is set in the outside of guide pillar 1, fixture block 7 is provided with draw-in groove 71, and draw-in groove 71 is established bounding means 51 for card.The outer rim of guiding groove 6 is higher than the outer rim of guide pillar 1, and guiding groove 6 exceeds the part of guide pillar 1 for buckle fixture block 7, prevents that guide pillar from moving up and down disengaging guide pin bushing 2 in process.
One end of tensile elements 4 is fastened on an end (being an end at fixture block 7 places) of the chute 21 on guide pin bushing 2.
