Abstract
The utility model discloses a metal rectangular square air duct flange fast connecting device, and belongs to the field of architecture. The utility model aims at providing a metal rectangular square air duct flange fast connecting device for adding an external part at a connecting part of a square air duct so that the square air duct is closely sealed and durable. A butt joint of the square air duct is provided with a straight angle connecting rod, a sealing pad is arranged on a contact gap of two straight angle connecting rods, a U-shaped clamp board with a turned ear is clamped outside two straight angle connecting rods, and a movable positioning pin with a hood penetrates through the U-shaped clamp board, the sealing pad and two straight angle connecting rods. The connecting device disclosed by the utility model is simple in structure and convenient to mount and use, the sealing material stacked between the straight angle connecting rods extending from the square air duct is used for effectively solving the sealing problem; through the clamping of the U-shaped clamp board, the strength of the straight angle connecting rods is increased, the sealing pad is clamped more tightly, and the sealing effect is more enhanced; by virtue of such a structure, the sealing property in use is enhanced, and the device is durable in use.
Description
Technical field
The utility model belongs to building field.
Background technique
It is more extensive that Fang Fengguan applies, rectangle side's airduct can be divided into according to purposes: cleaning system is sent airduct back to, industry supply and exhaust ventilation duct, central air-conditioning ventilation duct, mining drainage gas pipe, environment friendly system suction airduct etc., in use, the connected portion of Fang Fengguan generally needs tight seal to fix, yet, existing being fixedly connected with is simple by common bolton substantially, in order to seal, may stamp foamed glue etc., although can be effective in a short time, but certainly lead to and come off for a long time, the phenomenons such as sealing Kaifeng, make the said equipment not reach desirable using effect.
Summary of the invention
The purpose of this utility model is the peripheral hardware part of connection part increase at rectangle side's airduct, the tight sealing of the side's of making airduct, permanent durable metal rectangular side's air duct flange Quick Connect Kit.
The joint of side's airduct of the present utility model has right angle connecting rod, in the contact gap of two right angle connecting rods, there is sealing gasket, with the U-shaped fastening board clip that turns ear, be held in two right angle connecting rods outsides, with the locating stud alives of crown cap, pass U-shaped clamping plate, sealing gasket and two right angle connecting rods.
The utility model is simple in structure, easy to install, sealing material on pad between the extended right angle of linking of square airduct connecting rod, effectively solve sealing problem, by U-shaped clamping plate, clamp again, increase the intensity of right angle connecting rod, simultaneously more fastening clamping sealing gasket, more strengthened sealing effect, by this kind of structure in use sealability strengthen, and durable for a long time.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The joint of the utility model side's airduct 1 has right angle connecting rod 6, in the contact gap of two right angle connecting rods 6, has sealing gasket 5, the general flexible barrier material that adopts of sealing gasket 5.With the U-shaped clamp 7 that turns ear 2, be clamped in two right angle connecting rod 6 outsides, after installation, the lower surface that turns ear 2 preferably can with the side surface of square airduct 1 docile only, with the locating stud alive 4 of crown cap 8 through U-shaped clamping plate 7, sealing gasket 5 and two right angle connecting rods 6.Block by top cap 8 one end of locating stud 4 alive, the other end can pass through bolton, also can on the locating stud 4 of living, have outside thread, at U-shaped clamping plate 7, be provided with locating stud 4 outside threads of living and want the internal thread mating, the locating stud 4 of living so just can be threaded connection, and is easy for installation and removal like this.The wherein setting of right angle connecting rod 6, as long as mate closely sealed being advisable with U-shaped clamping plate 7.
