Description

A kind of composite door

Technical field

The utility model relates to class technical field, especially relates to the composite door that a kind of timber makes.

Background technology

Composite gate usually with timber for main material makes, manufacture craft not only considers good looking appearance, the more important thing is whether structure design is yielding, cracking etc. directly has influence on the quality problems in application life, and reasonably structure also can strengthen the sound insulation of door, moistureproof effect simultaneously.Publication No. is CN101936118A, date of publication is disclose a kind of preparation method exempting to paint composite gate in the Chinese patent document on January 5th, 2011, its door-plate face comprises the internal hilar plate face be attached on a skeleton and the external door panel face be attached on internal hilar plate face, door limit comprises inner door side plate, external door side plate and side door side plate, door side plate, external door side plate and side door side plate form the door limit with U-type groove jointly, again door skeleton is embedded in the U-type groove on door limit, owing to being applied in U-type groove in the stressed complete set of door skeleton, a limit is very easily damaged, not resistance to permanent use.Publication No. is CN103726759A, date of publication is disclose a kind of door in the Chinese patent document on April 16th, 2014, be made up of header board, rear plate and framework, this header board and this rear plate are separately fixed at the both sides of framework, this framework is order font, is filled with fine and close foaming material in three cavitys that this header board, this rear plate and this framework surround.Front and rear panels are just simple is in the structure shown here fixed together with framework, and therefore structure is firm not, and long-time use very easily deforms and causes damage.

Utility model content

The utility model is for the shortcoming of prior art, and technical problem to be solved is to provide a kind of composite door, by the stressed mode that is uniformly dispersed, strengthens the fastness of structure, increases the service life.

The utility model makes above-mentioned technical problem be solved by the following technical programs.

A kind of composite door, comprise external door panel, internal hilar plate and framework, framework fixes the periphery of block at external door panel and internal hilar plate, between external door panel and internal hilar plate, filler is set, the left and right moulding that framework comprises upper and lower symmetrically arranged upper and lower moulding and is symmetrical set, the two ends of upper and lower moulding are extended with at least one tenon respectively to outside along its length, the medial surface of left and right moulding are provided with the tongue-and-groove matched with tenon and are positioned at the draw-in groove matched with external door panel and internal hilar plate tongue-and-groove both sides.In the structure shown here, the medial surface of left and right moulding is provided with tongue-and-groove and the draw-in groove shared composite contact pressure from inside and outside door-plate and moulding up and down, the pressure that effective dispersion is too concentrated makes mutual CONTACT WITH FRICTION position uniform stressed, avoid the phenomenon of over-stressed fatigue damage, make structure more sturdy and durable, add application life.

As preferably, the degree of depth of tongue-and-groove is not less than the degree of depth of draw-in groove.

As preferably, tenon and tongue-and-groove are all in swallow-tail form or trapezoidal.

As preferably, the dual-side of left and right moulding is extended with flange towards inner side.

As preferably, the length of flange is 1/1 to five/3rd of external door panel and internal hilar plate length.

As preferably, upper and lower moulding lower edges flushes with the lower edges of external door panel and internal hilar plate respectively.

The beneficial effects of the utility model:

1. add structural strength, more sturdy and durable, not fragile.

2. manufacture craft is simple, easily makes, is conducive to batch production and applies.

Accompanying drawing explanation

Fig. 1 is the main TV structure schematic diagram of one of the present utility model;

Fig. 2 is the A-A place cross-sectional view of Fig. 1;

Fig. 3 is a kind of cross-sectional view of left and right of the present utility model moulding.

In figure: 1-external door panel, 2-internal hilar plate, 3-upper frame bar, moulding under 4-, the left moulding of 5-, the right moulding of 6-, 7-tenon, 8-tongue-and-groove, 9-draw-in groove, 10-flange.

Detailed description of the invention

Also by reference to the accompanying drawings the utility model is described in detail below by embodiment.

A kind of composite door of the utility model as shown in Fig. 1 Fig. 2, comprise external door panel 1, internal hilar plate 2 and framework, framework fixes the periphery of block at external door panel 1 and internal hilar plate 2, between external door panel 1 and internal hilar plate 2, filler is set, sound insulation, moistureproof effect can be played according to the actual required foaming material that adds.Framework comprises upper and lower symmetrically arranged upper frame bar 3 and lower moulding 4 and the left moulding 5 be symmetrical set and right moulding 6, upper frame bar 3 and lower moulding 4 are clamped in upper end between external door panel 1 and internal hilar plate 2 and bottom respectively, and the lower edges of upper frame bar 3 and lower moulding 4 flushes with the lower edges of external door panel 1 and internal hilar plate 2 respectively.The two ends of upper frame bar 3 and lower moulding 4 are extended with a tenon 7 respectively to outside along its length, as shown in Figure 3, the medial surface of left moulding 5 and right moulding 6 is provided with the tongue-and-groove 8 matched with the tenon 7 on upper frame bar 3 and lower moulding 4, and be also provided with the draw-in groove 9 matched with external door panel 1 and internal hilar plate 2 being positioned at tongue-and-groove 8 both sides, firmly be combined into one with left moulding 5 and right moulding 6 to make upper frame bar 3 and lower moulding 4, and more solid carrying is from the contact of external door panel 1 and internal hilar plate 2, the degree of depth that tongue-and-groove 8 is set can be selected to be greater than the degree of depth of draw-in groove 9.In order to strengthen the frictional force between tenon 7 and tongue-and-groove 8 further, also tenon 7 and tongue-and-groove 8 can be set to the swallow-tail form that cooperatively interacts or trapezoidal (not shown).As a kind of embodiment, in order to improve the clamping force to external door panel 1 and internal hilar plate 2, prevent long-time use from loosening phenomenon occurring, can preferably the dual-side of left moulding 5 and right moulding 6 towards inner side extended flange 10, flange 10 plays the effect of auxiliary clamp location external door panel 1 and internal hilar plate 2.The length of flange 10 can appropriateness be selected between external door panel 1 and 1/1 to five/3rd of internal hilar plate 2 length, is chosen as 1/4th as shown in Figure 3.

The utility model is not limited to above-described embodiment, external door panel, the embodiment of other malformation that equivalence is replaced in the middle of the known technology that the contour structures of internal hilar plate and framework and connected mode each other also can adopt those skilled in the art to obtain or prior art, as long as belong to technical conceive of the present utility model or spirit, by arranging tongue-and-groove and the draw-in groove shared composite contact pressure from inside and outside door-plate and moulding up and down on the medial surface of left and right moulding, to realize effectively disperseing too concentrated pressure and making mutual CONTACT WITH FRICTION position uniform stressed, premature fatigue is avoided to damage, make structure more sturdy and durable for the purpose of embodiment all drop in protection domain of the present utility model.
