Description
(1) technical field
The utility model relates to a kind of up-down rotary blade fan.
(2) background technique
Existing rotary blade fan comprises support, be located at the column of these support both sides and be located between this two column and be positioned at the rotary blade fan of said support top; The both sides of said rotary blade fan all are connected with said column through elevation and subsidence regulating device; This elevation and subsidence regulating device comprises the guide pin bushing that is connected with rotary blade fan; Guide pin bushing is sleeved on the column, laterally is provided with screw on the guide pin bushing, and an adjusting nut is against on the column after passing screw.During use, turn on adjusting nut, sliding guide sleeve need to be adjusted to rotary blade fan the position, the inner end of adjusting nut is pushed against on column tightening adjusting nut more then, thereby rotary blade fan is fixed on the position that needs.Because when regulating, need the loosening simultaneously controlling device that is positioned at rotary blade fan two, this regulates with regard to two people of needs, regulates and gets up not to be very convenient.
(3) summary of the invention
Have above-mentioned deficiency in the existing technology in order to overcome, the utility model provide a kind of simple in structure, go up and down to regulate the rotary blade fan that goes up and down easily and fast.
The technological scheme that the utility model solves its technical problem is: a kind of up-down rotary blade fan; Comprise support, be located at the column of these support both sides and be located between this two column and be positioned at the rotary blade fan of said support top; The both sides of said rotary blade fan all are connected with said column through elevation and subsidence regulating device, and said elevation and subsidence regulating device comprises and is sleeved on the said column and can be provided with the slide block of slippage up and down in this up-down guide pin bushing along the said column up-down guide pin bushing of slippage up and down; The top of this slide block is provided with the controlling rod of slippage up and down; The lower end of this controlling rod contacts with said slide block, and stretch out outside the said up-down guide pin bushing upper end of this controlling rod, and the below of said slide block is provided with spring; The middle part of said slide block is provided with groove; Be equipped with the elastic damping sheet in this groove, the head of this elastic damping sheet is fixed in the said up-down guide pin bushing after passing said groove, and the afterbody of this elastic damping sheet can contact with said column.
Further, said up-down guide pin bushing comprises going up and down following guide pin bushing and the up-down upper guide bush that is positioned at guide pin bushing top under this up-down, is convenient to install.
The utility model in use, both hands are positioned on the elevation and subsidence regulating device of rotary blade fan both sides and push controlling rod downwards, controlling rod promotes slide block and moves down; Spring is compressed; The elastic damping sheet is separated until elastic damping sheet and column along slippage in the groove of slide block, and both hands continue to pin controlling rod and move up or down rotary blade fan and get final product, and when being adjusted to the position that needs, unclamps both hands; Slide block moves up under the effect of spring; Elastic damping sheet in the groove of slide block stretches out and contacts with column, clamps column then rotary blade fan is fixed on the position that needs, thereby realize the adjusting of rotary blade fan adjustable height.
The beneficial effect of the utility model is: adopt said structure, the adjustable height that only needs a people just can carry out rotary blade fan is regulated, and adjusting is got up very convenient, fast, and the utility model is simple in structure, compact.
(4) description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the enlarged diagram of the elevation and subsidence regulating device of the utility model.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1, Fig. 2; A kind of up-down rotary blade fan comprises support 1, is located at the column 2 of these support 1 both sides and is located between this two column 2 and is positioned at the rotary blade fan 3 of said support 1 top, and the both sides of said rotary blade fan 3 all are connected with said column 2 through elevation and subsidence regulating device 4; Said elevation and subsidence regulating device 3 comprises and being sleeved on the said column 2 and can be along the up-down guide pin bushing of said column slippage about in the of 2; Be provided with the slide block 5 of slippage up and down in this up-down guide pin bushing, the top of this slide block 5 is provided with the controlling rod 6 of slippage up and down, and the lower end of this controlling rod 6 contacts with said slide block 5; Stretch out outside the said up-down guide pin bushing upper end of this controlling rod 6; The below of said slide block 5 is provided with spring 7, and the middle part of said slide block 5 is provided with groove 8, is equipped with elastic damping sheet 9 in this groove 8; The head of this elastic damping sheet 9 is fixed in the said up-down guide pin bushing after passing said groove 8; The afterbody of this elastic damping sheet 9 can contact with said column 2, and said up-down guide pin bushing comprises going up and down following guide pin bushing 10 and the up-down upper guide bush 11 that is positioned at guide pin bushing 10 tops under this up-down, is convenient to install.
The utility model in use, both hands are positioned on the elevation and subsidence regulating device 4 of rotary blade fan 3 both sides and push controlling rod 6 downwards, controlling rod 6 promotes slide blocks 5 and moves down; Spring 7 is compressed; Elastic damping sheet 9 is separated until elastic damping sheet 9 and column 2 along slippages in the groove of slide block 58, and both hands continue to pin controlling rod 6 and move up or down rotary blade fan 3 and get final product, when being adjusted to the position of needs, unclamp both hands; Slide block 5 moves up under the effect of spring 7; Elastic damping sheet 9 in the groove 8 of slide block 5 stretches out and contacts with column 2, clamps column 2 then rotary blade fan 3 is fixed on the position that needs, thereby realize the adjusting of rotary blade fan 3 adjustable heights.
