Abstract

The utility model relates to a multi-section telescopic rod used for sunning clothes, sunning sheets, etc. The utility model is characterized in that the multi-section telescopic rod is formed like that an eccentric cam device are connected with a plurality of tubes with different specifications according to thin-thick order, and the eccentric cam device is composed of an embolism and a hoop sheathed on a neck of the embolism. Because the utility model is connected by using the eccentric cam device, the use is very convenient, and a centerline of the eccentric cam device is placed to be coincident to a coincident of the multi-section rod by rotating a tube to a hemicycle to realize free stretching and shrinking. The utility model is very convenient, and is convenient for storing and carrying after using. The utility model adopts anode treatment on aluminium alloy surfaces, the clothes can not fade and turn yellow during clothes sunning, and the rod is easy to keep clean. The utility model can also be used as a flagpole to build a mat shelter, awning supporting frames, etc. besides used for the clothes sunning and sheet sunning.

Description

The multi-joint telescoping bar

The utility model relates to a kind of multi-joint telescoping bars such as clothing, cool quilt list that are used to shine.

The clothes airing rod of using in the family is with long bamboo bar mostly now, rests for a long time outside the balcony, and is easy to crack through exposing to the sun and rain, and shone clothes and taken in, and can't shelve again at home, and each receipts are shone and quite felt trouble, and put garments out in the sun, and easily turn to be yellow, fade.

The utility model purpose is exactly the shortcoming that overcomes existing clothes airing rod, provides a kind of scalable, receives and shines conveniently, can not ftracture, and does not dye the multi-joint telescoping bar of color.

The technical solution of the utility model is finished like this, it is by the pipe of many different sizes, connector is formed between pipe, and characteristics are to be with eccentric cam device that clip forms by embolism and neck thereof to connect thin thick many different pipes in turn and form the multi-joint telescoping bar.In order to limit pole when extending, not coming off, it connects, from carefully to thick connect in turn from stopper slot of coupling part roll extrusion of each root pipe of second pipe, the diameter of stopper slot is less than the eccentric cam device external diameter, pole just obtains spacingly when flexible like this, and pipe is from carefully to slightly.Radical and every length can be decided as required, adjacent connection two tubes, a thin tube outer diameter should be less than thick ips, are made of in eccentric cam device and adjacent two pipes that are connected embolism and clip thereof to be formed centrally off-centre, like this when needs are flexible, turne tube makes cam gear and two pipe central lines, and is so just freely scalable, finishes flexible, angle of turne tube again, just can fix, just not flexible of pole, very easy to use.

The utility model embodiment is further specified in conjunction with the accompanying drawings.

By shown in Figure 1, state diagram when stretching for the multi-joint telescoping bar, it is from carefully forming to thick 5 pipe joints, and blocking respectively is equipped with in front and back, and Fig. 2 is the state diagrams when contracting of 5 section telescopic bars.Fig. 3 is a structural representation between 5 section telescopic bars, the two adjacent pipes, by shown in Figure 3,

1,5 is a tubule and extra heavy pipe of adjacent connection, they are hollow circular-tubes of being made by aluminium alloy, the surface is through anodized, connector employing between the pipe is with clip 4 by embolism 3 and its neck 7 and forms eccentric cam device, embolism structure such as Fig. 5, Fig. 4, shown in Figure 6, the offset at embolism neck and embolism center is 1.8mm, it is by PEF, nylon, plastics etc. are made, the embolism upper end is fixed by pin 2 and pole 1 inwall, yoke configurations such as Fig. 7, shown in Figure 8, it is also by can be by PEF, nylon, plastics etc. are made, the inside and outside circle off-centre of clip, its offset size is 1.8mm, as shown in Figure 8, clip 4 lower ends have the breach of a 6mm, be a plane in the above, clip inside and outside circle off-centre, offset is 1.8mm, clip just is stuck on the neck 7 of embolism, embolism is decided according to the internal diameter size that need are connected pipe with the clip size, the embolism upper end is loaded in the pipe 1, can be fixing by pin 2, the maximum radial dimension of embolism is less than the ips of required fixedly downlink connection, the clip maximum radial dimension is greater than the ips 0.7～0.8mm of required connection, in the present embodiment by 5 pipes from carefully to slightly connecting in turn, the sub-external diameter of tubule should be less than the extra heavy pipe internal diameter of adjacent connection, present embodiment is 1.3mm, in order to prevent that the elongation of more piece bar pole from the time skidding off, apart from stopper slot 6 of pipe end 60～75mm roll extrusion, the diameter of stopper slot can not skid off when pole is flexible like this less than the maximum outside diameter size of eccentric cam device from the coupling part of second each root pipe of pipe.

The utility model is because the connection of employing eccentric cam device is therefore, very easy to use, even only need pipe is rotated the central lines of half-turn eccentric cam device center line and more piece bar, very convenient with regard to retractable, rotate promptly fixing, be convenient to after collect and carry, the employing aluminium alloy anode oxide is handled, and shines the clothing jaundice of can not fading, and pole easily keeps clean, it is except being used for cool solarization clothing, can also make flagpole, build interim mat shelter, usefulness such as canopy support.

Claims

1, the multi-joint telescoping bar a kind of by many pipes, that connector is formed between pipe is characterized in that, the multi-joint telescoping bar is with the eccentric cam device that clip (4) forms by its neck of embolism (3) (7) and constitutes carefully slightly to connect many pipes in turn.

2, multi-joint telescoping bar according to claim 1 is characterized in that, described eccentric cam device upper end is fixed with tubule (1) inwall that needs to be connected, and the lower end is in the adjacent extra heavy pipe (5), and forms off-centre with two tubes.

3, according to the described multi-joint telescoping bar of claim 1, it is characterized in that, with the thin multi-joint telescoping bar that slightly connects in turn that arrives, apart from pipe end 60～75mm roll extrusion a stopper slot (6) is arranged from the coupling part of each root pipe of second pipe, the diameter of stopper slot is less than the maximum outside diameter size of eccentric cam device.
