Duct fixing structure

Technical field

The utility model is related to air conditioning for automobiles field of accessories, more particularly to a kind of duct fixing structure.

Background technology

Air conditioner system air blast system coordinates overlap joint to constitute by air-conditioner host+air channel+air outlet grille, its system it is main Effect is to provide driver's cabin cool and comfortable or warm air duct, and it is purposive blow to corresponding human body, this is One of difficult point of uniting is leaked out for lap-joint, if overlap joint is bad to easily lead to leaking out for lap-joint, subtracts air-out volume It is small, it possibly even can produce wind in lap-joint and make a whistling sound, influence vehicle comfortableness.

Assembling is completed using monoblock type grafting between existing air channel and air-conditioner host, its junction uses sponge strip after assembling Sealed, using overall plug-in type, rigging position/state is very difficult to ensure, so that in the presence of hidden danger of leaking out, it is impossible to effectively improve Air-conditioning assembly reliability：Sponge drops phenomenon in the assembling for causing sponge to be pasted not strongly and producing, simultaneously because rigging position without Method ensures, in assembling process, assembling deflection easily occurs, compress, and meanwhile the loose phenomenon of pressure, and be inconvenient to dismantle.

Utility model content

The utility model uses monoblock type grafting to solve existing air channel with air-conditioner host, and rigging position/state is very Difficulty goes to ensure, and the problem of assemble inconvenience.

The utility model provides a kind of duct fixing structure to achieve these goals, and it is arranged on the air port of air-conditioner host Place, including dual-pipe clamp, the dual-pipe clamp it include pipe clamp and lower tube clip, the lower tube clip and the bottom phase in air-conditioner host air port Even, one end and the lower tube clip of the upper pipe clamp are hinged, and the other end is snapped connection with the lower tube clip；In the upper pipe clamp Portion is detachably connected by bolt with the lower tube clip.

Preferably, upwardly extended in the end of the lower tube clip on a plugboard, the plugboard and offer spliced eye； The end of the upper pipe clamp has extended downwardly a crook, and the crook is caught on after stretching out the plugboard along the spliced eye The top margin edge of the spliced eye.

Preferably, the middle part of upper pipe clamp be provided with via, the middle of lower tube clip vertically be provided with a screwed pipe；It is described Bolt is connected after passing through via with the screwed pipe.

Preferably, the via is the heavy platform hole opened up downwards.

Preferably, multiple positioning convex are respectively arranged with the inwall of lower tube clip bottom and both sides, the end in air channel Outer wall is provided with multiple locating slots, and the positioning convex is fastened in the locating slot.

Preferably, the dual-pipe clamp is made of secondary injection molding.

Effect of the present utility model is：This programme realizes the connection of air channel and air-conditioner host using openable pipe clamp, Its middle part is fixed using bolt, is used at opening and is snapped connection mode, it is ensured that air channel and air-conditioner host connection effect, is facilitated The detachable maintaining of air-conditioner host.

Brief description of the drawings

, below will be to institute in embodiment in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art The accompanying drawing needed to use is briefly described, it should be apparent that, drawings in the following description are only described in the utility model Some embodiments, for those of ordinary skill in the art, other accompanying drawings can also be obtained according to these accompanying drawings.

Embodiment

In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing pair The utility model is further detailed.

Referring to shown in Fig. 1 to Fig. 5, a kind of duct fixing structure provided for the utility model embodiment, in air-conditioner host 2 Air port at a dual-pipe clamp 3 is installed, it is used to fix air channel 1, and it includes pipe clamp 31 and lower tube clip 32, the lower tube clip 32 It is connected with the bottom outer end in the air port of air-conditioner host 2, one end of upper pipe clamp is hinged with the lower tube clip, the other end and the lower tube clip Snap connection；The middle part of upper pipe clamp 31 is detachably connected by bolt 4 with lower tube clip 32.That is, this programme use can be beaten The pipe clamp opened realizes the connection of air channel and air-conditioner host, and its middle part is fixed using bolt, using mode is snapped connection at opening, really Air channel 1 and air-conditioner host connection effect have been protected, the detachable maintaining of air-conditioner host is facilitated.

Specifically, with reference to shown in Fig. 3 and Fig. 5, a plugboard 321 is upwardly extended in the end of lower tube clip, on plugboard Spliced eye 322 is offered, a crook 311 has been extended downwardly in the end of upper pipe clamp 31, crook 311 is stretched along spliced eye 322 Go out after plugboard 321 to catch on the top margin edge of spliced eye.Certainly, its buckle can also use conventional hinge type buckle structure, but its Structure is more complicated.

In addition, as shown in figure 4, via is provided with the middle part of upper pipe clamp 31, in the middle of lower tube clip 32 being provided with vertically One screwed pipe 323；Bolt is connected after passing through via with screwed pipe 323, the fixed company at pipe clamp 31 and the middle part of lower tube clip 32 in realization Connect, the reliability of connection in the middle part of upper and lower pipe clamp is ensure that using bolt mode.

For more preferably, after being fixed in order to avoid bolt, its head is spilt, to influence the installation of other car body components, In this programme, the via opened up in the middle part of upper pipe clamp is the heavy platform hole 312 opened up downwards, wherein, heavy platform hole 312 is used to accommodate spiral shell The head of bolt.

In addition, multiple positioning convex 324 can be also set on the inwall of lower tube clip bottom and both sides, as shown in figure 3, in wind The end outer wall in road is provided with multiple locating slots, and positioning convex 324 is fastened in locating slot, further increases air channel in pipe clamp On fixed effect, it is ensured that junction connection is reliable.

The dual-pipe clamp is made of secondary injection molding, further to improve the sealing effectiveness of dual-pipe clamp.

Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for One of ordinary skill in the art, can be with a variety of in the case of without departing from spirit and scope of the present utility model Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be understood For the limitation to the utility model claims.
