Description

Airduct connects the mechanism that is flexible coupling that framework is used

Technical field

The utility model belongs to pipe ventilated facility technology field, is specifically related to a kind of airduct and connects the mechanism that is flexible coupling that framework is used.

Background technique

In the occasion that disposes central air-conditioner for example hotel, wineshop, place of public amusement, office space, stadiums, showground and various conference centres or the like, usually central air-conditioner is equipped with, in addition, production firm for example the production firms such as production firm, papermaking, weaving, medicine and food of electronic and electrical equipment also be no lack of the central air-conditioner of disposing.For cold air or heating installation are transported to each zone, for example be transported to each room in hotel, need claim airduct again by means of pipeline so, consider factors such as vibration factor, sound insulation and noise reduction factor, modular repair and replacing, usually need tediously long airduct is divided into several sections (claiming the airduct section again), adopt transition apparatus to connect between the adjacent sections, for example to length be the airduct of 100m be divided into ten each be the pipeline section of 10m, then by corresponding transition apparatus connection.

In the prior art to be used for the transition apparatus that adjacent two airduct sections implement to be flexible coupling be by prefabricated and fill the post of for the canvas of cylinder, one end of canvas and the mouth of pipe of one of them airduct section are fixed, and the other end of canvas and the mouth of pipe of another airduct section are fixed, means of fixation is colligation.The advantage of this transition apparatus of being filled the post of by canvas is simple in structure and has economically cheapness, but there is following problem: the one, sealing is relatively poor, being easy to generate gas leakage is escape of gas, both has been unfavorable for the temperature of guaranteeing that the field of employment is required, again inaction ground consumes energy; The 2nd, construction trouble, because during with the airduct colligation of the canvas of flexibility and metal material, working strength of workers is big, and quality can not get guarantee, even same builder also can't ensure the conformity of the colligation effect of all colligation points; The 3rd, undermine airduct easily, because if the colligation tension then can make the airduct distortion, and colligation is loose excessively, then canvas can take off from the airduct upstream.

Use airduct to connect framework the connection effect that adjacent airduct section enforcement connects will obviously be better than aforesaid canvas,, only need to use corresponding fasteners such as screw because need not to adopt colligation.But, because airduct connects framework and is made into using, also need connected element to implement to connect each other, promptly a pair of airduct is connected framework and connects by connected element (can be described as the mechanism that is flexible coupling), and the structure of the mechanism that is flexible coupling whether reasonable can have influence on equally airduct connect framework self structure and with the airduct section between be connected effect.To this, the applicant carries out the examination of repaying repeatedly, has successfully released concrete structure described below.

Summary of the invention

Task of the present utility model is to provide a kind of and can connects convenient connection of framework with airduct and help to make airduct to connect framework successfully to escape to embody cooling or heat supply requirement energy-conservation and the guarantee field of employment to the external world with the air that prevents in the airduct of using that the airduct section connects; help alleviating the intensity of workmen's construction operation and guarantee two needs airduct sections connected to one another are reliably connected, be of value to protection airduct section and use and avoid connecting the mechanism that is flexible coupling that framework is used because of construction causes the airduct that decreases the airduct section.

Task of the present utility model is finished like this, a kind of airduct connects the mechanism that is flexible coupling that framework is used, described airduct connect framework comprise each by each other structure identical and quantity respectively be four moulding and be used for a pair of airduct that the corner connector that the quantity that four mouldings enforcements are connected equates with the quantity of described moulding constitutes is connected the framework body; The length direction of described moulding has a pin groove and a hook board slot, pin groove and hook board slot are separated, and constitute vertical relation between the two, described corner connector has the pin of a pair of relation of form right angle each other, this is pegged graft with the pin groove on the moulding to one of them pin in the pin and cooperates, grafting cooperates and this is to the pin groove on another pin in the pin and another root moulding, the described mechanism that is flexible coupling comprises the submissive body and a pair of air sac sealing bar of the cylinder that is shaped as the two ends perforation, wherein air sac sealing bar in the edge of one side of submissive body and a pair of air sac sealing bar is fixed, and another root air sac sealing bar in the edge of the opposite side of submissive body and a pair of air sac sealing bar is fixed, one side of air sac sealing bar has Stamping Steel Ribbon hook head, Stamping Steel Ribbon hook head is embedded in the described hook board slot, and hook together with the reverse hook teeth at the notch position of hook board slot, and the opposite side of air sac sealing bar constitutes the sealed bladder pipe of hollow, and the sealed bladder pipe is stuck in outside the hook board slot.

In a specific embodiment of the present utility model, described submissive body is canvas, polyurethane film or coated cloth.

In another specific embodiment of the present utility model, described coated cloth is the coated cloth of glass fiber woven cloth surface-coated flexible PVC coating.

In another specific embodiment of the present utility model, the two ends of the length direction of described moulding and respectively offer a location flange hole and one first fixed hole at notch position corresponding to described pin groove, and the middle part at the length direction of moulding offers at least one second fixed hole, and respectively constituting one, a side of described a pair of pin compels to hold plate, locating flange and the 3rd fixed hole, compeling to hold plate compels to be held on the cell wall of described pin groove, locating flange is based in to be compeled to hold on the plate, and this locating flange protrudes in described locating flange hole, and the 3rd fixed hole is corresponding with described first fixed hole.

In another specific embodiment of the present utility model, the middle part of described corner connector offers 2 the 4th fixed holes.

The technological scheme that the utility model provides need not to connect the framework body by means of any fastening piece and a pair of airduct by the mechanism that is flexible coupling that is made of submissive body and a pair of air sac sealing bar and is connected; connecting the framework body by airduct again is connected with the airduct section; can embody and the airduct section between connect effect; cold and hot air can not occur and escape into the external world from airduct; thereby embody energy-conservation; connect conveniently and connect reliably with the airduct section; need not to resemble and implement colligation the prior art; both help to alleviate assembler's working strength, be beneficial to the protection airduct again.
