Description

Technical Field

[0001] The utility model belongs to the technical field of air duct construction, in particular to an air duct insulation nail tightener. Background Art

[0002] Insulation nails are engineering plastic expansion nails used to secure insulation foam to air ducts. They consist of a base plate and an aluminum nail positioned in the middle of the base plate. After cleaning the duct surface, glue is applied to the base plate to secure it firmly to the duct wall. After a period of rest, insulation material is laid, and the aluminum nail penetrates the insulation foam to secure it. However, when attaching the base plate to the duct wall, construction workers sometimes forget to press firmly, resulting in a loose bond and poor quality. Utility Model Content

[0003] The purpose of the utility model is to provide a heat-insulating nail tightener for an air duct.

[0004] The utility model is realized by the following measures: a heat-insulating nail presser for air ducts, characterized in that it comprises a U-shaped clamping plate clamped on two opposite side walls of the air duct, the two side plates of the U-shaped clamping plate being located on the outside of the air duct and the upper ends of the inner walls of the side plates being provided with downwardly bent elastic plates, the elastic plates being clamped on the side walls of the air duct;

[0005] The bottom plate of the U-shaped splint is provided with a strip opening located between the two side plates, and the bottom plate is symmetrically provided with sliding grooves on both sides of the strip opening, and the sliding grooves are slidably provided with a pressing structure;

[0006] The compression structure includes a sliding member with both ends positioned within the chute. The sliding member is provided with a threaded hole, into which a stud is threadedly mounted. The end of the stud closest to the air duct is provided with several compression members capable of pressing against the base plate of the insulation nail. The sliding member moves along the chute, allowing the aluminum nail of the insulation nail to pass through the gaps between the compression members. The stud has a channel passing through the center of the stud, which is provided with a compression member and has a width greater than the outer diameter of the insulation nail.

[0007] Furthermore, in order to reduce weight, a weight-reducing hole is concentrically provided on the stud, and a hand-held rod for facilitating manual rotation of the stud is fixedly provided on the inner wall of the weight-reducing hole.

[0008] Furthermore, an oblique supporting plate is fixedly provided on the inner side of the suspended end of the elastic plate, and the inner end of the oblique supporting plate is upwardly tilted toward the open end of the U-shaped clamping plate.

[0009] Furthermore, top screws are provided through the two side plates of the U-shaped clamping plate through threaded connection.

[0010] Furthermore, since some insulation nails have circular holes on their base plates, adhesive residue may remain inside or around the holes when adhesive is used for fixing. Using a larger-sized pressing member may cause the nails to stick together later. Therefore, the pressing members are formed of several round rods, the outer diameter of which is larger than, and preferably slightly larger than, the inner diameter of the circular holes on the insulation nail base plate. When in use, the round rods are preferably positioned away from all circular holes on the base plate, thereby reducing the risk of sticking.

[0011] Furthermore, the pressing member is a plurality of arc-shaped plates uniformly distributed on the stud in the circumferential direction.

[0012] Furthermore, the sliding member includes a circular disc located on the outside of the base plate, the threaded hole is concentrically arranged on the circular disc, and a connecting rod facing the base plate is symmetrically arranged on the outer wall of the circular disc. The connecting rod is located inside the strip-shaped opening and a sliding plate inserted into the sliding groove is arranged on the outside of the end of the connecting rod.

[0013] Furthermore, the side plates of the U-shaped splint, the elastic plates connected to the side plates, and the oblique supporting plates connected to the elastic plates are integrally manufactured.

[0014] Furthermore, both ends of the slide extend out of the chute, and a limit plate is provided on the protruding end. A screw is provided through the limit plate via a threaded connection, and the screw can press against the side wall of the bottom plate of the U-shaped clamping plate. This can achieve the tightening of the sliding member, and when the screw is not provided, the friction between the slide and the chute can be increased.

[0015] Usage: Glue the insulation nails to the outer wall of the air duct according to the design size. After all the insulation nails on the same row are installed, install the U-shaped splint on the adjacent outer wall of the air duct. During installation, the outer wall of the air duct is inserted from the open end of the U-shaped splint and squeezes the elastic plate. When the outer wall where the insulation nails are installed is pressed against the inclined support plate, the two elastic plates are clamped on the outer wall of the air duct to achieve fixation. In order to ensure the clamping effect, the top screw can also be rotated so that the top screw presses the elastic plate tightly.

[0016] After the U-shaped splint is fixed, the sliding part is slid according to the installation distance of the insulation nails. During the sliding process, the space between the pressing parts allows the insulation nails to pass through. The sliding part can pass between multiple insulation nails until it corresponds to the corresponding insulation nail. At this time, the aluminum nail is concentric with the stud and is located in the channel. The stud is rotated, and the stud drives the pressing part to move toward the bottom plate of the insulation nail until it is pressed against the bottom plate. The stud is further pre-tightened to make the pressing part press against the bottom plate.

[0017] The beneficial effects of the technical solution provided by the embodiment of the utility model are: the glued insulation nails can be compressed, the installation quality of the insulation nails can be improved, and the installation effect of the insulation cotton can be guaranteed.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0029] See also Figures 1-8 A duct insulation nail 7 tightener, characterized in that it includes a U-shaped clamping plate 1 clamped on two opposite side walls of the duct 8, the two side plates 102 of the U-shaped clamping plate 1 are located on the outside of the duct 8 and the upper end of the inner wall of the side plate 102 is provided with a downwardly bent elastic plate 103, and the elastic plate 103 is clamped on the side wall of the duct 8;

[0030] The bottom plate 101 of the U-shaped splint 1 is provided with a strip opening between the two side plates 102, and slidable grooves 10101 are symmetrically provided on both sides of the strip opening on the bottom plate 101, and the slidable grooves 10101 are provided with a pressing structure;

[0031] The compression structure includes a sliding member 2 with both ends positioned within a chute 10101. The sliding member 2 is provided with a threaded hole into which a stud 3 is threadedly mounted. The end of the stud 3, near the air duct 8, is provided with several compression members that can press against the base plate 701 of the insulation nail 7. The sliding member 2 moves along the chute 10101, allowing the aluminum nail 702 of the insulation nail 7 to pass through the gaps between the compression members. The stud 3 has a channel passing through its center, which is provided with a compression member and has a width greater than the outer diameter of the insulation nail 7.

[0032] Furthermore, in order to reduce weight, a weight-reducing hole is concentrically provided on the stud 3 , and a hand-held rod 301 for facilitating manual rotation of the stud 3 is fixedly provided on the inner wall of the weight-reducing hole.

[0033] An oblique support plate 5 is fixedly provided on the inner side of the suspended end of the elastic plate 103 , and the inner end of the oblique support plate 5 is upwardly tilted toward the open end of the U-shaped clamping plate 1 .

[0034] The two side plates 102 of the U-shaped clamping plate 1 are penetrated by a top screw 6 through a threaded connection.

[0035] Since some insulation nails 7 have circular holes 703 on the bottom film 701, when adhesive is used for bonding and fixing, there will be adhesive residue inside or around the circular holes 703. If a larger-sized pressing member is used, the two will stick together later. Therefore, the pressing members are made of a plurality of round rods 4. The outer diameter of the round rods 4 is larger than the inner diameter of the circular holes 703 on the bottom film 701 of the insulation nail 7, preferably slightly larger. When in use, the round rods 4 are preferably able to avoid all the circular holes 703 on the bottom film 701, so as to reduce the possibility of sticking.

[0036] The pressing members are a plurality of arc-shaped plates uniformly distributed on the stud 3 in the circumferential direction.

[0037] The sliding member 2 includes a disc 201 located on the outside of the base plate 101, a threaded hole is concentrically arranged on the disc 201, and a connecting rod 202 facing the base plate 101 is symmetrically arranged on the outer wall of the disc 201. The connecting rod 202 is located inside the strip-shaped opening and a slide 203 inserted into the slide groove 10101 is arranged on the outside of the end of the connecting rod 202.

[0038] The side plate 102 of the U-shaped clamping plate 1, the elastic plate 103 connected to the side plate 102, and the inclined supporting plate 5 connected to the elastic plate 103 are made in one piece.

[0039] Both ends of the slide plate 203 extend out of the chute 10101, and the protruding ends are provided with limit plates 204. The limit plates 204 are provided with screw rods 205 through the screw connection. The screw rods 205 can be pressed against the side wall of the bottom plate 101 of the U-shaped clamping plate 1. This can achieve the tightening of the sliding member 2. If the screw rods 205 are not provided, the friction between the slide plate 203 and the chute 10101 can be increased.

[0040] Usage: Glue the insulation nails 7 to the outer wall of the air duct 8 according to the design size. After all the insulation nails 7 on the same row are installed, install the U-shaped splint 1 on the adjacent outer wall of the air duct 8. During installation, the outer wall of the air duct 8 is inserted from the open end of the U-shaped splint 1 and squeezes the elastic plate 103. When the outer wall of the insulation nail 7 is installed on the inclined support plate 5, the two elastic plates 103 are clamped on the outer wall of the air duct 8 to achieve fixation. In order to ensure the clamping effect, the top screw 6 can also be rotated so that the top screw 6 presses the elastic plate 103 tightly.

[0041] After the U-shaped splint 1 is fixed, the sliding part 2 is slid according to the installation distance of the insulation nail 7. During the sliding process of the sliding part 2, the insulation nail 7 can pass through the space between the pressing parts. The sliding part 2 can pass between multiple insulation nails 7 until it corresponds to the corresponding insulation nail 7 and the aluminum nail 702 is concentric with the stud 3 and is located in the channel. The stud 3 is rotated, and the stud 3 drives the pressing part to move toward the bottom plate 701 of the insulation nail 7 until it is against the bottom plate 701. The stud 3 is further pre-tightened so that the pressing part is against the bottom plate 701.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
