Abstract
The utility model relates to the technical field of shutter fittings, in particular to a non-segment fixed length expansion link, which consists of an upper link and a lower link. The lower link forms a hole along the axial direction; the bottom end of the upper link is provided with a first via hole horizontally; a friction stick is inserted and arranged at the first via hole; the upper link is inserted in the hole; the section of the upper link is a polygon; the section of the hole is a polygon matched with the upper link. A light-adjusting stick of the utility model is composed of the upper link and the lower link which are sheathed, and can be stretched to cooperate with a longer window; the light-adjusting stick of the utility model can also be retracted and packed with the shutter, thus reducing the package cost; the upper link can be positioned at any position when stretching so that the link of the utility model is convenient for use.
Description
Technical field:
The utility model relates to shutter accessory technical field, the particularly section of nothing fixed length expansion link.
Background technology:
Along with improving constantly of people's living standard, many designs product more attractive in appearance has also entered in the life of ordinary people, and shutter is exactly one of them.In order to prevent light irradiation, people can hang curtain on window, if but when curtain pulled on, light from outside was blocked fully and is made and indoorly become very dark; Shutter can stretch, and can form certain space between each blade, so just can an amount of light be introduced indoorly according to people's different demands, and also unusual fashion of shutter is installed.The blade of shutter can rotate and make each blade horizontal substantially, and this moment, translucent effect was best, and laterally rotation is by the control of light modulation rod for the control blade, and the light modulation nose is connected with rotating connector, and rotating connector is connected with blade.General, if window is than higher, so, the light modulation rod is also long, so that people can use, but, brought inconvenience with regard to the packing of giving shutter like this, shutter can be folded together and be put in the packing box, and long light modulation rod then needs to join in addition packing box, so just increased packing cost, and transportation is also inconvenient.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art not have section fixed length expansion link, and it can be packed together with shutter, thereby reduces packing cost, and it is very easy to use.
For achieving the above object, the utility model adopts following technical scheme:
It comprises upper connecting rod, lower link, and lower link moulding vertically is porose; The upper connecting rod bottom laterally offers first through hole, and first through hole is inserted with friction-bar; Upper connecting rod inserts in the hole.
The cross section of described upper connecting rod is a polygon, and the cross section in hole is the polygon that mates with upper connecting rod.
Described upper connecting rod bottom is the cutting portion with unfilled corner, and first through hole runs through cutting portion; Lower link is run through in hole on the lower link.
Described lower link top offers second through hole.
Be plugged with auxiliary block in described first through hole, be tied with connecting line on the auxiliary block, the other end of connecting line is connected with upper connecting rod.
The beneficial effects of the utility model are that the light modulation rod is made of upper and lower pull bar socket, and upper connecting rod can move up and down, and it can play two effects, the firstth, can stretch, and use to cooperate long window; The secondth, it can shrink, and can pack together with shutter, thereby reduce packing cost; Upper connecting rod can fix on any position during stretching, and is very easy to use.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model
Schematic diagram when Fig. 2 is the utility model contraction
Fig. 3 is STRUCTURE DECOMPOSITION figure of the present utility model
The specific embodiment:
The following stated only is a better embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See accompanying drawing 1-3, the utility model comprises upper connecting rod 10, lower link 20, and upper and lower pull bar 10,20 adopts plastic material to make lower link 20 moulding vertically porose 22; Upper connecting rod 10 bottoms laterally offer first through hole 14, first through hole, 14 places are inserted with friction-bar 30, the main effect of friction-bar 30 is frictions of increase and lower link 20, when upper connecting rod 10 is stretched, can fix in a certain position and not glide, friction-bar 30 also adopts has certain flexible plastic material; Upper connecting rod 10 inserts in the hole 22, upper connecting rod 10 can be along the hole 22 upper and lower moving realizing stretch, because friction-bar 30 is in compressive state in hole 22, so friction-bar 30 has horizontal elastic force, friction-bar 30 makes upper connecting rod 10 locate any position in hole 22 by this elastic force.
The cross section of described upper connecting rod 10 is a polygon, and the cross section in hole 22 is and the polygon of upper connecting rod 10 couplings in the time of could guaranteeing like this to rotate lower link 20 upper connecting rod 10 is rotated simultaneously, and then blade of louver window is rotated.
Described upper connecting rod 10 bottoms are that cutting portion 12, the first through holes 14 with unfilled corner run through cutting portion 12; The effect of upper connecting rod 10 bottom moulding unfilled corners is to make friction-bar 30 conveniently movings, and when assembling, also is easy in upper connecting rod 10 patchholes 22.
Described lower link 20 tops offer second through hole 24, and upper connecting rod 10 is pulled outwardly, and when friction-bar 30 was stuck in second through hole, 24 positions, friction-bar 30 is outwards elongation under the elastic force effect, and upper connecting rod 10 can not pulled out in the hole 22 of lower link 20.
Be plugged with auxiliary block 40 in described first through hole 14, be tied with connecting line 42 on the auxiliary block 40, the other end of connecting line 42 is connected with upper connecting rod 10, upper connecting rod 10 can not broken away from lower link 20 when stretching, certainly, the length of connecting line 42 can avoid upper connecting rod 10 to pull out in hole 22 less than the length in hole 22 like this, influences result of use.
During packing, blade of louver window can fold puts into packing box together, and the utility model light modulation rod also can fold: upper connecting rod 10 is got final product to pressing down to make in its hole that is incorporated into lower link 20 22.
Upper connecting rod 10 of the present utility model is connected with rotating connector, and rotating connector is connected with shutter.During use,, then upper connecting rod 10 upwards can be pulled out, make the elongation of light modulation rod, to be convenient for people to use if window is higher.
The utility model can be used as the light modulation rod of shutter, also can be used for other field.
The utility model can stretch, and uses to cooperate long window; Can also shrink,, thereby reduce packing cost so that pack together with shutter.
