Abstract

Provided is a dragline type window cleaner composed of a driving portion and a brushing tool portion. On the driving portion, the dragline is dragged to drive a dragline wheel to drive a gear to rotate and the gear is also driven. The two ends of a shaft are connected with the gear and a disc. The gear and the disc synchronously rotate to drive racks to do intermittent, linear and back-and-forth movement via a connecting bar, and then the racks meshing drives the gear and the disc to do back and forth movement within a certain range through the gear arranged at one end of the shaft. A driving connecting bar is connected with the gear to drive a slide block arranged inside a rail groove of the brushing tool to be engaged with a driven connecting bar to ultimately ensure the brushing tool to horizontally, up and down and back and forth scouring the windows. The utility model has the advantages that every corner of the windows is capable of being wiped by adjusting fixing positions and choosing brushes of different sizes and the utility model is adaptable for windows of different sizes.

Description

A kind of dragline type window cleaner

Technical field

The utility model relates to a kind of laborsaving, can clean by interior exterior window again, and safe and reliable dragline type window cleaner, especially adopt parallelogram principle to realize the scouring up and down of brushing tool, make brushing tool reach maximum scouring scope, also meet the traditional wiping window mode of people.

Background technology

Known wiping window is the very housework of trouble always, and when cleaning high-rise outdoor glass, also has bigger potential safety hazard.The window cleaner of Chu Shouing utilizes mostly and installs stock additional in the market, enlarges the wiping scope, or utilizes the suction of magnet to fix scraper cleaning exterior window.But all have defective, can not satisfy both laborsaving, again can in exterior window clean and safe and reliable requirement.Increasing along with city high rise building, a large amount of daylighting strengthens window size, needs a kind of novel window cleaner solve the problems referred to above.

Summary of the invention

In order to overcome the deficiency of existing window cleaner on security and labour saving technique, the utility model provides a kind of window cleaner, this window cleaner utilizes parallel four limit row principles, adopted the transmission mechanism of machine formula, realized the scouring up and down of brushing tool, make brushing tool reach maximum scouring scope, also meet the traditional wiping window mode of people.

The technical scheme that its technical problem that solves the utility model adopts is: the utility model mainly partly is made of spill shell, fastener, rope hauling device, reduction gearing, eccentric wheel, rack-and-pinion, crank block and brushing tool etc.By fastener the stay cord window cleaner is fixed, regulated fastening bolt this window cleaner is fixed on the sash of different-thickness; The similar common dragline type curtain of rope hauling device is being grown the ball that processes a series of compact arrangement on the rope, and it is being embedded in the groove of roller, and when the pulling rope, ball can drive the roller quick rotation; Roller links to each other with pinion is concentric, and rotation is transferred to gear wheel, plays the effect of deceleration and amplifying moment; Gear wheel links to each other by main shaft is coaxial with a disk, and disk and main shaft are connected with tooth bar by an eccentric ratio as one, just drives disk and rotate together when gear wheel rotates, and eccentric ratio rotates thereupon, drives tooth bar and does the intermittence linear reciprocating motion; By gear at one end is installed, drive it by tooth bar and its engagement and do gyration within the specific limits again.Be connected with gear by the drive connecting rod bar motion is reached slide block in the brushing tool rail groove, cooperate follower link, realize that the level of brushing tool in window frame pumps, and realizes the purpose of cleaning.

The beneficial effects of the utility model are, by adjusting fixedly seat, and select the brush of different size for use, can clip each corner of window, and adapt to the window of different size, and are widely applicable.

Description of drawings

Fig. 1 is a general assembly drawing of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

In the above accompanying drawing: 1, stay cord; 2, pin; 3, connecting rod; 4, pin; 5, bolt; 6, gear; 7, fastening bolt; 8, fixed muffle; 9, bull wheel; 10, gear; 11, split pin; 12, split pin; 13, brush; 14, slide block; 15, follower link; 16, drive connecting rod; 17, bolt; 18, pin; 19, gear; 20, disk main shaft; 21, tooth bar; 22, spill shell.

Below in conjunction with drawings and Examples the utility model is further specified.

Referring to illustrated in figures 1 and 2, a kind of dragline type window cleaner is made up of brushing tool 13 and spill shell 22 and internal structure thereof. One tapped fixed muffle 8 is housed on the spill shell 22; Fastening bolt 7 is contained in the fixed muffle 8, manually the turn spiral shell Bolt makes the screw rod spinning in and out with fixing window cleaner; Fixed muffle 8 overcoats have bull wheel 9 and gear 10, bull wheel 9 and gear 10 Connect together and with fixed muffle 8 matched in clearance; Gear 10 is meshed with gear 6, consists of a speed reduction gearing and also can put High-torque; Gear 6 is fixed on on the disk main shaft 20, drives main shaft and disk and rotates together; Eccentric ratio 3 one ends pass through Pin 4 is connected with disk, and the other end connects and composes the class eccentric mechanism by pin 2 and tooth bar 21, and gyration is converted into the gap The property reciprocating motion; Tooth bar 21 is meshed with gear 19, consists of the rack-and-pinion transmission; Gear 19 consists of hinged pair with pin 18; Drive connecting rod 16 1 ends are connected on the gear 19 by bolt 5, and the other end is connected on the slide block 14 by split pin 11; From Moving connecting rod 15 1 ends are connected on the spill shell 22 by bolt 17, and the other end is connected on the slide block 14 by split pin 12; Slide block is contained in the rail groove with brush 13.

The specific embodiment

At first recess is stuck on the window frame, positions.By fastening bolt 7, tighten fixing.Pulling stay cord 1, drive bull wheel 9, driven gear 10 rotates, and be transferred to gear 6, rotate by disk main shaft 20 driver plates, drive tooth bar 21 by connecting rod 3 and make intermittent linear reciprocating motion, by gear 19 at one end is installed, drives it by the tooth bar engagement and make back rotation within the specific limits again.Drive connecting rod 16 is connected with gear 19 motion is reached slide block in the brushing tool rail groove, cooperates follower link 15, realizes that the level of brushing tool in window frame up and down reciprocatingly clean.
