Description

Technical Field

[0001] The utility model belongs to the technical field of composite aluminum profiles, and in particular relates to an aluminum profile for windows with sound insulation and heat insulation functions. Background Art

[0002] Window aluminum profiles can be generally divided into the following two categories according to the different locations of use: window frame aluminum profiles and window sash aluminum profiles. Among them, the size of window frame aluminum profiles is relatively large, so it is easier to install sound insulation and heat insulation materials on them, and the benefits are greater.

[0003] On the other hand, the common existing sound insulation and heat insulation aluminum profiles mainly include: an aluminum profile body, sound insulation and heat insulation cotton, and a shell for the sound insulation and heat insulation cotton. The sound insulation and heat insulation cotton is fully filled in the shell in advance, and then the shell is inserted into the cavity of the aluminum profile body, so that the sound insulation and heat insulation aluminum profile can be simply and efficiently manufactured.

[0004] For example, a Chinese utility model patent with authorization announcement number CN219773952U and authorization announcement date 2023.09.29 discloses a heat-insulating and sound-insulating thermally-insulated aluminum profile for doors and windows, including an aluminum profile body, a card slot is provided on the top surface of the aluminum profile body, a second lightening hole is provided through the bottom end of the aluminum profile body, sound-absorbing cotton is arranged inside the second lightening hole, and a first lightening hole is provided on both sides of the card slot inside the aluminum profile body, and thermal insulation cotton is arranged inside the first lightening hole.

[0005] The aluminum profile in this utility model patent has the following principles and advantages: thermal insulation cotton is arranged inside the first lightening hole, so as to further improve the thermal insulation efficiency of the aluminum profile body itself; sound-absorbing cotton is arranged inside the second lightening hole, so as to improve the sound insulation effect of the aluminum profile body and the use performance of the aluminum profile body; and the first support plate, the second support plate, the first support rod and the second support rod are arranged for coordinated use, so as to facilitate the support of the second lightening hole, thereby avoiding the collapse of the second lightening hole and improving the service life of the aluminum profile body.

[0006] However, in actual use, the aluminum profile still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0007] First, the second support plate and the two sound-absorbing cotton structures are independent of each other, and the three need to be inserted into the lower cavity of the aluminum profile one by one or together, which is relatively inefficient or difficult;

[0008] Second, the gasket structure is only slightly mounted on the side of the aluminum profile. The structural strength is insufficient and the gasket is relatively easy to fall off.

[0009] Therefore, in summary, there is an urgent need for a new type of aluminum profile for windows, which has an easy-to-install lower sound insulation and heat insulation structure and a stable installation of the sealing gasket in the window sash groove. Utility Model Content

[0010] The utility model provides an aluminum profile for windows with sound insulation and heat insulation functions, which can be achieved by arranging vertical plates, horizontal plates, curved plates, inner plates, sealing strip slots, mounting hole units, anti-retraction sealing strip units, upper sound insulation and heat insulation strip units, slotted units, and lower sound insulation and heat insulation support frame units on a bottom plate, so that: 1. the lower sound insulation and heat insulation support frame unit is a whole, and its installation method is relatively simple and quick; 2. the anti-retraction sealing strip unit is engaged with the horizontal plate and plugged into the inner plate for anti-retraction, so the installation stability is relatively high, and the window sash aluminum profile is not easy to be squeezed out and fall off.

[0011] The technical solution adopted by the utility model to solve the above-mentioned problems is: an aluminum profile for windows with sound insulation and heat insulation functions, the structure of which includes a bottom plate, a vertical plate, a horizontal plate, an arc plate and an inner plate for constituting the aluminum profile body, and also includes a sealing strip groove arranged on the upper surface of the horizontal plate, a mounting hole unit arranged on the inner plate, an anti-backward sealing strip unit arranged on the sealing strip groove and the mounting hole unit, an upper sound insulation and heat insulation strip unit arranged between the arc plate and the horizontal plate, a slotted unit arranged on the upper surface of the bottom plate and the lower surface of the horizontal plate, and a lower sound insulation and heat insulation support frame unit arranged on the slotted unit.

[0012] A further preferred technical solution is that the mounting hole unit includes a countersunk hole opened outward from the side surface of the inner plate close to the arc-shaped plate and used for engaging and mounting the anti-retraction sealing strip unit.

[0013] A further preferred technical solution is that the anti-retraction sealing strip unit includes a sealing strip main body arranged on the inner plate and with the lower end inserted into the sealing strip groove, a cylindrical block arranged on the sealing strip main body and used for inserting into the countersunk hole, and a frustum block arranged on the cylindrical block and used for engaging the countersunk hole.

[0014] A further preferred technical solution is that: the mounting hole unit further includes a circular hole arranged on the inner plate; and the anti-backward sealing strip unit further includes a plug-in rod arranged on the sealing strip body and used for inserting into the circular hole.

[0015] A further preferred technical solution is that: the number of the countersunk holes is 2, which are respectively arranged at two sides of all the circular holes.

[0016] A further preferred technical solution is that the upper sound insulation and heat insulation strip unit includes a tubular outer shell, and a first sound insulation and heat insulation strip arranged in the tubular outer shell.

[0017] A further preferred technical solution is that the slotting unit includes side grooves arranged on the upper surface of the bottom plate and the lower surface of the transverse plate, and inner grooves arranged between pairs of the side grooves.

[0018] A further preferred technical solution is that the lower sound insulation and heat insulation support frame unit includes two side support plates respectively arranged on the two pairs of the side grooves, two inner support plates respectively arranged on the two pairs of the inner grooves, forming cross plates arranged in pairs between the side support plates and the inner support plates, a second sound insulation and heat insulation strip arranged between the upper and lower forming cross plates, and an intermediate connecting cross plate arranged on the two inner support plates.

[0019] A further preferred technical solution is that the number of the intermediate connecting transverse plates is 3-6, and the thickness is smaller than that of the forming transverse plates.

[0020] A further preferred technical solution is that: the upper surface of the horizontal plate is also provided with a positioning groove for punching holes located above the middle connecting horizontal plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0033] As attached Figure 1-6 As shown, an aluminum profile for windows with sound insulation and heat insulation functions, the structure includes a bottom plate 11, a vertical plate 12, a horizontal plate 13, a curved plate 14 and an inner plate 15 for constituting an aluminum profile body, and also includes a sealing strip groove 1 arranged on the upper surface of the horizontal plate 13, a mounting hole unit 2 arranged on the inner plate 15, an anti-retraction sealing strip unit 3 arranged on the sealing strip groove 1 and the mounting hole unit 2, an upper sound insulation and heat insulation strip unit 4 arranged between the curved plate 14 and the horizontal plate 13, a slotted unit 5 arranged on the upper surface of the bottom plate 11 and the lower surface of the horizontal plate 13, and a lower sound insulation and heat insulation support frame unit 6 arranged on the slotted unit 5.

[0034] In this embodiment, the structure of the existing aluminum profile body is composed of: a bottom plate 11, two vertical plates 12, a horizontal plate 13, two arc plates 14 and two inner plates 15. There is no visible boundary line between the above plates, and the aluminum profile body is formed in one piece. The shape of the arc plate 14 is essentially an "inverted L-shaped" bent plate with a circular arc chamfer.

[0035] At this point, the aluminum profile body has an upper left cavity and an upper right cavity for installing the two upper sound insulation and heat insulation strip units 4, and the sliding groove for installing the window sash is between the two cavities. In other words, the window aluminum profile is a window frame aluminum profile.

[0036] In addition, an integral and larger lower cavity is formed at the lower part of the aluminum profile body for installing one lower sound insulation and heat insulation support frame unit 6. The lower sound insulation and heat insulation support frame unit 6 can be installed by directly aligning and inserting it into the cavity.

[0037] Finally, the number of the anti-retraction sealing strip units 3 is 2, which are respectively located on both sides of the sliding groove, and are used to always stick to the window sash to ensure sufficient sound insulation and heat insulation effects. It is engaged with the sealing strip card slot 1 and inserted into the mounting hole unit 2 to prevent retraction, thereby ensuring that the sliding window sash is not easily squeezed out and falls off.

[0038] The mounting hole unit 2 includes a countersunk hole 201 opened outward from the side of the inner plate 15 close to the arc plate 14 and used for engaging and mounting the anti-retraction sealing strip unit 3 .

[0039] In this embodiment, the larger end of the countersunk hole 201 faces the arc plate 14, so that although the insertion of the anti-retraction sealing strip unit 3 is relatively laborious, a relatively large anti-retraction effect can be obtained after being inserted into place, which can greatly improve the installation stability of the anti-retraction sealing strip unit 3.

[0040] The anti-retraction sealing strip unit 3 includes a sealing strip body 301 which is arranged on the inner plate 15 and the lower end of which is inserted into the sealing strip groove 1, a cylindrical block 302 which is arranged on the sealing strip body 301 and used to be inserted into the countersunk hole 201, and a truncated cone block 303 which is arranged on the cylindrical block 302 and used to engage with the countersunk hole 201.

[0041] In the embodiment, the diameter of the thicker end of the truncated cone block 303 corresponds to the diameter of the larger end of the countersunk hole 201 , and the diameter of the thinner end of the truncated cone block 303 corresponds to the smaller end of the countersunk hole 201 .

[0042] Therefore, the truncated cone block 303 can obtain an anti-retraction effect on the countersunk hole 201, and the truncated cone block 303 will not protrude, otherwise it will block the insertion and installation action of the upper sound insulation and heat insulation strip unit 4.

[0043] In addition, the length and diameter of the cylindrical block 302 correspond to the smaller end of the countersunk hole 201 , so that the cylindrical block 302 can hold the sealing strip body 301 and the frustum block 303 .

[0044] Finally, the anti-rollback sealing strip unit 3 is made of ordinary rubber.

[0045] The mounting hole unit 2 further includes a circular hole 202 disposed on the inner plate 15 ; the anti-backward sealing strip unit 3 further includes an inserting rod 304 disposed on the sealing strip body 301 and used for inserting into the circular hole 202 .

[0046] In this embodiment, due to:

[0047] First, the larger end of the countersunk hole 201 faces inward, so it is generally necessary to open it from the inside outward, which is relatively difficult, especially in the middle of the length direction of the aluminum profile for the window;

[0048] Second, the force required for the engagement operation between the countersunk hole 201 and the cylindrical block 302 and the truncated cone block 303 is relatively large, and too many such engagement anti-retraction structures will increase the difficulty of installing the anti-retraction sealing strip unit 3 .

[0049] Therefore, the sealing strip body 301 can also achieve a sufficient and relatively easy insertion and installation effect through the interference fit between the plug-in rod 304 and the circular hole 202 .

[0050] At this time, for example, if the diameter of the smaller end of the countersunk hole 201 is 10 mm, the diameter of the thicker end of the truncated cone block 303 is set to 14 mm, the diameter of the thinner end and the cylindrical block 302 is set to 9 mm, and the diameter of the plug rod 304 is set to 12 mm. Finally, the above-mentioned sufficient anti-backward effect and interference fit effect are guaranteed.

[0051] The number of the countersunk holes 201 is two, which are respectively arranged at two sides of all the circular holes 202 .

[0052] In this embodiment, the countersunk hole 201 is arranged at the most side, which can be convenient for opening. In other words, the equipment required for opening the countersunk hole 201 only needs to be slightly inserted into the upper left cavity and the upper right cavity, which is very convenient.

[0053] The upper sound insulation and heat insulation strip unit 4 includes a tubular shell 401 and a first sound insulation and heat insulation strip 402 arranged in the tubular shell 401 .

[0054] In this embodiment, the material of the tubular shell 401 is the existing thin aluminum plate, and the sound insulation and heat insulation material of the first sound insulation and heat insulation strip 402 and the lower sound insulation and heat insulation support frame unit 6 are all existing common foam cotton.

[0055] When the aluminum profile for windows is produced, the upper sound insulation and heat insulation strip unit 4 and the lower sound insulation and heat insulation support frame unit 6 are already prefabricated, and a total of three strip-shaped parts can be directly inserted into the corresponding cavities of the aluminum profile body.

[0056] The cross-sectional profile shape of the tubular housing 401 is determined by the shape of the cavity specifically surrounded by the transverse plate 13, the arc-shaped plate 14 and the inner plate 15, and can be, for example, a 1 / 4 circle sector shape.

[0057] The slotting unit 5 includes side slots 501 arranged on the upper surface of the bottom plate 11 and the lower surface of the transverse plate 13 , and inner slots 502 arranged between the side slots 501 .

[0058] In this embodiment, the number of the side grooves 501 and the inner grooves 502 is four in total.

[0059] The lower sound insulation and heat insulation support frame unit 6 includes two side support plates 601 respectively arranged on the two pairs of side grooves 501, two inner support plates 602 respectively arranged on the two pairs of inner grooves 502, forming cross plates 603 arranged in pairs between the side support plates 601 and the inner support plates 602, a second sound insulation and heat insulation strip 604 arranged between the upper and lower forming cross plates 603, and an intermediate connecting cross plate 605 arranged on the two inner support plates 602.

[0060] In this embodiment, a side support plate 601, an inner support plate 602 and two molding transverse plates 603 together form a rectangular cavity for filling the second sound insulation and heat insulation strip 604. The lower sound insulation and heat insulation support frame unit 6 includes a total of two rectangular cavities, which are also located on both sides of the window sash slide. In other words, the window aluminum profile has a double sound insulation and heat insulation effect on the indoor side and the outdoor side.

[0061] If the installation hole a needs to be opened, it will also penetrate all the intermediate connecting horizontal plates 605 so that the installation bolts can pass through the entire window aluminum profile, thereby reinforcing the installation on the window wall.

[0062] Therefore, the two second sound insulation and heat insulation strips 604 are separated on both sides in order to avoid the above-mentioned mounting bolts.

[0063] The number of the intermediate connecting transverse plates 605 is 3-6, and the thickness is smaller than the forming transverse plates 603 .

[0064] In this embodiment, the intermediate connecting transverse plate 605 is used to achieve a suitable compromise and balance between the difficulty of opening the installation hole a and the structural strength of the lower sound insulation and heat insulation support frame unit 6 through the structural characteristics of "many and thin".

[0065] The upper surface of the transverse plate 13 is also provided with a positioning groove 7 for punching holes at a position above the middle connecting transverse plate 605 .

[0066] In this embodiment, the functions of the positioning groove 7 for punching holes mainly include the following two functions:

[0067] First, it is to avoid the situation that the left and right positions are difficult to determine when the mounting hole a is opened, and to prevent the mounting bolts from hitting the inner support plate 602;

[0068] Second, provide the mounting bolts with a proper "countersunk hole" effect, without ensuring that the bolt head is completely retracted inside it so that it will not get stuck in the window sash.

[0069] In addition, in the length direction of the aluminum profile for windows, there are no clear restrictions on the density and spacing of the installation holes a, and they can be selected as needed.

[0070] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
