Abstract

The utility model discloses an aluminum profile for sealing an expansion module, which comprises the aluminum profiles and rubber seal strips, wherein the aluminum profiles are fixedly mounted at the peripheries of the inner port and the outer port of a movable module of the expansion module; the bottom parts of the rubber seal strips are clamped and inserted in the notches of the aluminum profiles; the cross section of each aluminum profile is T-shaped and provided with a hollow rectangle; the opposite side edges of the aluminum profile with the hollow rectangle are fixed at the peripheries of the inner port and the outer port of the movable cabin; and the outer side of the aluminum profile with the hollow rectangle adopts a T-type groove structure. Whether the movable cabin is in the transversal expansion state or in the contraction state, the contacted places are sealed. The utility model can improve the heat-insulating performance, the water-sealing performance and the hermetic sealing performance of the extension cabin and the fixed cabin effectively.

Description

Expansion tank sealed aluminum section bar

Technical field

The utility model relates to a kind of seal structural part of expansion tank, and particularly a kind of aluminium section bar that sealing band is installed in the junction of expansion tank moving part and fixed part belongs to the shape technical field.

Background technology

The envelope both sides can laterally be stretched out when expansion tank or expansion van were a kind of parking the motor-driven cabin or self-propelled vehicle, this device is mainly used in field activity, and can be used as meeting room, commander office, communication workstation, medical aid chamber etc. needs the envelope of certain width to use.The moving part of existing expansion tank or expansion van and the sealing of fixed part mostly are directly and fixedly mount rubber strip on the metal mold faces; because rubber strip length is difficult to flatten and installs firmly, use the rubber strip breakage occurs through regular meeting for a long time and causes the junction infiltration of expansion tank and sealed cabin or the phenomenon of leaking.

Summary of the invention

Flatten and install unstable shortcoming for the sealing band that solves existing expanded shelter moving part and fixed part is difficult, the utility model provides a kind of aluminium section bar that is directly installed on the expansion tank moving part and can directly clamps rubber weather strip, can improve the heat retaining property and the air-tightness of expanded shelter moving part and fixed part.

The utility model is achieved by the following technical programs:

A kind of expansion tank sealed aluminum section bar comprises aluminium section bar, rubber weather strip, and described aluminium section bar is fixedly mounted on respectively on the periphery of the inside and outside port of portable cabin of expansion tank, and the bottom card of rubber weather strip is inserted in the notch of aluminium section bar; The cross-sectional plane of described aluminium section bar is that an end has the on an empty stomach T shape of rectangle, and described aluminium section bar has on the periphery of inside and outside port that the opposite side of rectangle on an empty stomach is fixed on portable cabin, and described expansion tank aluminium section bar has on an empty stomach that the outside of rectangle is provided with the T type groove structure.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid expansion tank sealed aluminum section bar, one side of wherein said sealing band is provided with several overhanging tooth, described several overhanging tooth is respectively high tooth, middle tooth and internal tooth, the bottom card of described sealing band is inserted in the T type groove of expansion tank aluminium section bar, and the high tooth of overhanging tooth, middle tooth and internal tooth and sealed cabin port constitute several sealing.

Because the utility model is separately positioned on the periphery of the inside and outside port of portable cabin, and has multiple-sealed between the sealed cabin port.No matter portable cabin is in is laterally stretched out the state of still regaining, and its contact position all is in sealing state, and the utility model has improved heat-insulating property, water sealing property and the gas sealing ability between expansion tank and the sealed cabin effectively.

Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is the vertical view cutaway drawing of aluminium section bar of the present utility model after installing on the expansion tank.

Fig. 2 is the I place partial enlarged view of Fig. 1.

Fig. 3 is the II place partial enlarged view of Fig. 1.。

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1 and Figure 2, aluminium section bar 4 of the present utility model is fixedly mounted on respectively on the periphery of portable cabin 2 inner port 22, external port 21 of expansion tank, and the bottom card of rubber weather strip 3 is inserted in the notch 41 of aluminium section bar 4.The cross-sectional plane of aluminium section bar 4 is that an end has the T shape of rectangle on an empty stomach, to improve the intensity of aluminium section bar 4; The opposite side that aluminium section bar 4 has a rectangle on an empty stomach is fixed on by riveted joint or other fixed forms on the periphery of inner port 21, external port 22 of portable cabin, and aluminium section bar 4 has on an empty stomach that the outside of rectangle is provided with T type groove 41 structures.

As Fig. 2, shown in Figure 3, a side of rubber weather strip 3 is provided with several overhanging tooth, and several overhanging tooth is respectively high tooth 31, middle tooth 32 and internal tooth 33, and the bottom card of rubber weather strip 3 is inserted in the T type groove 41 of expansion tank aluminium section bar.

Figure 2 shows that portable cabin 2 is in overhanging state, at this moment, the overhanging tooth in three roads that is fixedly mounted on the sealing band 3 of portable cabin 2 inner port 21 is positioned within the inwall boss 11 of sealed cabin 1, and the portable cabin 2 and the junction formation of sealed cabin 1 are tightly connected.

When portable cabin 2 was in retracted state, the overhanging tooth in three roads that is fixedly mounted on the sealing band 3 of portable cabin 2 inner port 21 was positioned at outside the inwall boss 11 of sealed cabin 1, and the portable cabin 2 and the junction formation of sealed cabin 1 are tightly connected.

In a word, no matter the portable cabin 2 of expansion tank is overhanging state or retracted state, and the utility model can both make the portable cabin 2 and the junction of sealed cabin 1 all be in sealing state, has improved gentle, the water tightness of heat retaining property of the portable cabin and the sealed cabin of expanded shelter.

In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
