Description

Technical Field

[0001] This application relates to the field of sheet metal technology, and more particularly to an aluminum alloy heat-insulating sheet metal incorporating heat-insulating material. Background Technology

[0002] In the construction industry, building materials come in a variety of materials, and materials with different properties have different functions. Thermal insulation boards, as a widely used material in the construction industry, play an important role in thermal insulation and heat preservation.

[0003] In related technologies, thermal insulation boards include various forms such as porous thermal insulation boards and vacuum thermal insulation boards, all of which have wide applications. Among them, vacuum thermal insulation boards have a vacuum space inside the board, so that there is no medium for heat conduction, thereby achieving thermal insulation effect.

[0004] Regarding the aforementioned technologies, the inventors discovered that vacuum insulation panels have good thermal insulation effects, but they are not easy to manufacture. Errors in the manufacturing process can cause air to enter the interior of the panels, resulting in air inside the panels that can conduct heat, thus affecting the thermal insulation performance of the panels. Therefore, improvements are needed. Summary of the Invention

[0005] In order to reduce the manufacturing difficulty of thermal insulation panels and improve vacuum degree and thermal insulation performance, this application provides an aluminum alloy thermal insulation panel incorporating thermal insulation material.

[0006] The technical solution provided in this application for an aluminum alloy thermal insulation board incorporating thermal insulation material is as follows:

[0007] An aluminum alloy heat-insulating panel incorporating heat-insulating material includes a panel body with a vacuum chamber inside. A vacuum extraction hole is formed on the surface of the panel body, communicating with the vacuum chamber. An elastic element is provided on the inner wall of the vacuum chamber. A sealing post is provided at one end of the elastic element near the vacuum extraction hole, and the sealing post is driven by the elastic element to abut against the vacuum extraction hole. A needle is provided on the side wall of the sealing post. A puncture hole is formed on the inner wall of the vacuum chamber on the side communicating with the vacuum extraction hole, allowing the needle to pass through. A sealing groove is formed inside the panel body, communicating with the puncture hole. A plastic bag is provided on the inner wall of the sealing groove away from the puncture hole. A limiting component is provided inside the vacuum chamber, connected to the sealing post and causing the elastic element to be in a compressed state.

[0008] By adopting the above technical solution, during the production and processing of the sheet material, a vacuum chamber space is reserved in the center of the sheet material, and a vacuum extraction hole is opened on the inner wall of one side of the vacuum chamber. When the sheet material is to be used on a building, the air in the vacuum chamber can be extracted simply by inserting the extraction pipe of the extraction device into the vacuum extraction hole, thus truly forming a vacuum space inside the vacuum chamber. When extracting the internal air, the extraction pipe of the extraction device will come into contact with the sealing column, thereby allowing the elastic element to be further compressed. This allows the limiting component to release the restriction on the sealing column. As the tube leaves the vacuum hole, the elastic element gradually returns to its original state, causing the sealing column to move towards the vacuum hole and eventually abut against it, thus sealing the plate body. During the movement of the sealing column, the needles on the side wall of the sealing column will abut against the puncture hole, thereby puncturing the rubber bag in the sealing groove, allowing the adhesive to flow out and seep into the puncture hole, so that the needles can adhere to the inner wall of the puncture hole. This fixes the sealing column by fixing the needles, thereby improving the airtightness of the plate body, effectively reducing the production difficulty of vacuum insulation plates, and improving the sealing performance of the plate body, resulting in high economic benefits.

[0009] Preferably, the sealing column includes a limiting block and a plug-in column. The elastic element is connected to the bottom wall of the limiting block, and the plug-in column is connected to the end of the limiting block away from the elastic element. The diameter of the limiting block gradually decreases from the end near the elastic element toward the end of the plug-in column. The inner wall of the vacuum chamber is provided with a limiting groove for the limiting block to abut against. The limiting groove communicates with the vacuum hole. The piercing needle is connected to the side wall of the limiting block, and the piercing hole is opened in the inner wall of the limiting groove.

[0010] By adopting the above technical solution, the sealing column is set as a connection between a limiting block and a plug-in column, so that after the sealing column is reset, it can abut against the inner wall of the limiting groove through the limiting block, thereby limiting the problem of the sealing column protruding from the vacuum hole due to excessive slippage of the sealing column, thus improving the sealing performance and practicality of the heat insulation board of this application.

[0011] Preferably, the inner wall of the sealing groove communicating with the puncture hole is provided with a positioning groove, the positioning groove is coaxial with the puncture hole, and the positioning groove is set in a constricted shape.

[0012] By adopting the above technical solution, the positioning groove can facilitate the flow of adhesive into the positioning groove, thereby allowing more adhesive to participate in the fixing and bonding of the needle and the inner wall of the puncture hole, thus improving the sealing effect and tightness of the needle, enabling the sealing column to be positioned more stably, and reducing the probability of the sealing column falling off from the vacuum hole.

[0013] Preferably, the inner wall of the sealing groove is provided with a plurality of seepage holes, and the plurality of seepage holes are all connected to the vacuum hole.

[0014] By adopting the above technical solution and opening seepage holes, the adhesive inside the sealing groove can seep into the vacuum hole through the seepage holes to connect the sealing column with the inner wall of the vacuum hole, thereby directly fixing the sealing column and effectively sealing the gap between the sealing column and the vacuum hole, further improving the sealing effect of the plate body of this application.

[0015] Preferably, the limiting component includes a limiting plate, a tension spring, and a hook plate. The limiting plate is connected to the bottom wall of the limiting block. One end of the tension spring is connected to the inner wall of the vacuum chamber. The hook plate is connected to the end of the tension spring that is away from the inner wall of the vacuum chamber. The limiting plate has a through slot along its thickness for the hook plate to pass through. The end of the hook plate that passes through the through slot is bent in the direction away from the vacuum hole. The bent part of the hook plate abuts against the inner wall of the limiting plate.

[0016] By adopting the above technical solution, after the hook-up piece passes through the hook-up slot of the limiting piece, it abuts against the side wall of the limiting piece through its own bent part, thereby limiting the limiting piece and the sealing post. This makes it difficult for the sealing post to move towards the vacuum hole under the elastic force of the elastic element, thus restricting and positioning the sealing post. When the suction pipe of the vacuuming device extends into the vacuum hole and abuts against the sealing post, the elastic element will be further compressed, causing the sealing post and the limiting piece to be pressed down. At this time, the bent part of the hook-up piece will lose the abutment of the limiting piece and will disengage from the hook-up slot through the tension spring. After the suction pipe of the vacuuming device leaves the vacuum hole, the sealing post will reset under the elastic force of the elastic element, thereby abutting into the vacuum hole and puncturing the plastic bag with a piercing needle to achieve sealing of the plate body of this application. The structure is simple, easy to implement, and has high practicality and convenience.

[0017] Preferably, the limiting assembly further includes a first limiting rod and a second limiting rod. The first limiting rod is connected to the inner wall of the vacuum chamber and is parallel to the extension and retraction direction of the tension spring. A first limiting sleeve is provided on the side wall of the hook piece, and the first limiting rod passes through the first limiting sleeve. The second limiting rod is vertically connected to the bottom wall of the vacuum chamber, and a second limiting sleeve is provided on the side wall of the limiting block, and the second limiting rod passes through the second limiting sleeve.

[0018] By adopting the above technical solution, the presence of the first limiting rod and the second limiting rod is respectively applicable to restricting the movement trajectory of the hanging piece and the sealing column, so that the hanging piece and the sealing column can move in a restricted manner according to their respective length directions. On the one hand, it can enable the hanging piece to maintain its horizontal state when the limiting piece moves, and on the other hand, it can enable the sealing column to be stably inserted into the vacuum hole, thereby improving the convenience of sealing the plate body of this application.

[0019] Preferably, the plate body includes a cover plate and a bottom plate, the vacuum chamber is opened on the surface of the bottom plate, the cover plate is embedded in the vacuum chamber and abuts against the inner wall of the vacuum chamber, and the vacuum hole is opened on the cover plate.

[0020] By adopting the above technical solution, the plate body is set in the form of a cover plate and a bottom plate, which facilitates the installation of the limiting components when manufacturing the plate body, and further improves the production convenience of the plate body of this application.

[0021] Preferably, both the cover plate and the bottom plate have heat-insulating cavities, which are filled with heat-insulating material.

[0022] By adopting the above technical solution, opening a heat insulation cavity and filling the heat insulation cavity with heat insulation material, the heat insulation performance of the plate body of this application can be further improved.

[0023] Preferably, the outer wall of the vacuum hole opposite to the vacuum chamber has a locking hole, a locking ring is provided in the locking hole, and a connecting hole is provided through the locking ring along the thickness direction. The peripheral wall of the sealing column opposite to the elastic element has a fixing hole corresponding to the connecting hole. A sliding groove is provided on the surface of the cover plate, and a locking pin is slidably connected in the sliding groove. The locking pin passes through the connecting hole and is inserted into the fixing hole. A locking element for fixing the locking pin is provided in the sliding groove.

[0024] By adopting the above technical solution, the locking ring can position the sealing column after it is reset by the locking element and the locking pin, thus allowing sufficient time for the adhesive to solidify. This allows the sealing column to be positioned during the solidification of the adhesive, effectively improving the stability of the connection between the plate body and the sealing column and its sealing performance.

[0025] Preferably, the locking component includes a ring cover and a fixing plate. The ring cover covers the surface of the locking ring, and the fixing plate is connected to the side wall of the ring cover. The fixing plate is embedded in a sliding groove. The bottom wall of the fixing plate has a fixing groove for the locking pin to be inserted. The end wall of the fixing plate opposite to the ring cover has a locking hole. A buffer spring is provided in the locking hole. The other end of the buffer spring is connected to a connecting post. The inner wall of the sliding groove has a connecting hole for the connecting post to be inserted.

[0026] By adopting the above technical solution, after the locking pin has locked the sealing column, it can still slide. By pushing the locking pin into the fixing groove, the movement of the locking pin can be restricted. After the locking pin is fixed, the locking member is pushed into the sliding groove, so that the connecting column is pushed into the connecting hole under the action of the buffer spring, thereby achieving the fixing and sealing of the plate body of this application.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During the production and processing of the sheet material, a vacuum chamber is pre-reserved in the center of the sheet material, and a vacuum extraction hole is opened on the inner wall of one side of the vacuum chamber. When the sheet material is to be used on a building, the air in the vacuum chamber can be extracted by inserting the extraction pipe of the extraction equipment into the vacuum extraction hole, thus creating a true vacuum space. When extracting the internal air, the extraction pipe of the extraction equipment will abut against the sealing post, thereby allowing the elastic element to be further compressed. This allows the limiting component to release the restriction on the sealing post. When the extraction pipe of the extraction equipment leaves the sealing post... During vacuuming, the elastic element will gradually recover, causing the sealing column to move towards the vacuum hole and eventually abut against it, thus sealing the plate body. During the movement of the sealing column, the needles on the side wall of the sealing column will abut against the puncture hole, thereby puncturing the rubber bag in the sealing groove, allowing the adhesive to flow out and seep into the puncture hole, so that the needles can adhere to the inner wall of the puncture hole. This fixes the sealing column by fixing the needles, thereby improving the airtightness of the plate body, effectively reducing the production difficulty of vacuum insulation plates, and improving the sealing performance of the plate body, resulting in high economic benefits.

[0029] 2. The limiting component of this application can release the restriction on the sealing column after the air in the vacuum cavity inside the plate body is extracted, so that the sealing column can automatically block the vacuum hole after the air extraction is completed, thereby ensuring the sealing of the inside of the plate body. The structure is simple and has high convenience and practicality. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses an aluminum alloy heat-insulating plate incorporating heat-insulating material. (Refer to...) Figure 1 and Figure 2 An aluminum alloy heat-insulating plate incorporating heat-insulating material is disclosed, comprising a plate body 1, the plate body 1 including a cover plate 11 and a bottom plate 12, a vacuum cavity 121 formed on the surface of the bottom plate 12, the size of the vacuum cavity 121 being adapted to the size of the cover plate 11, the cover plate 11 being embedded in the vacuum cavity 121 and abutting against the inner wall of the vacuum cavity 121, the cover plate 11 being connected to the inner wall of the vacuum cavity 121 by welding. In this embodiment, the plate body 1 is made of aluminum alloy, and heat-insulating cavities 4 are formed in both the cover plate 11 and the bottom plate 12, the heat-insulating cavities 4 being filled with heat-insulating material 41, thereby effectively improving the heat insulation performance of the plate body 1 of this application, the heat-insulating material 41 being a mixture of asbestos and rock wool.

[0036] Reference Figure 1 and Figure 2A vacuum hole 111 is provided through the cover plate 11 along its thickness direction, and the vacuum hole 111 communicates with the vacuum chamber 121. An elastic element 122 is provided on the bottom wall of the vacuum chamber 121. In this embodiment, the elastic element 122 is a spring. One end of the elastic element 122 is connected to the bottom wall of the vacuum chamber 121 by adhesive, and the other end is connected to a sealing post 2 by adhesive. The sealing post 2 includes a limiting block 21 and a plug-in post 22. The limiting block 21 and the plug-in post 22 are integrally formed. The elastic element 122 is connected to the bottom wall of the limiting block 21 by adhesive, and the plug-in post 22 is connected to the end of the limiting block 21 away from the elastic element 122. The straight edge of the limiting block 21... The end of the sealing column 2 gradually decreases in size from the end closest to the elastic element 122 toward the end of the insertion post 22, forming a frustum shape. A limiting groove 115 is provided on the side of the cover plate 11 facing the vacuum chamber 121. The shape of the limiting groove 115 is adapted to the shape of the limiting block 21. The limiting groove 115 is coaxially opened with the vacuum hole 111. The sealing post 2 is driven by the elastic element 122 and abuts into the vacuum hole 111. At this time, the limiting block 21 will abut into the limiting groove 115, thereby limiting the excessive movement of the sealing post 2. When the air in the vacuum chamber 121 is extracted by the pumping equipment, the sealing post 2 can seal the vacuum hole 111.

[0037] Reference Figure 1 and Figure 2 The side wall of the limiting block 21 is integrally formed with a number of needles 211, which are evenly distributed along the circumferential direction of the limiting block 21. The inner wall of the limiting groove 115 is provided with a number of puncture holes 112 for the needles 211 to pass through, which are evenly distributed along the circumferential direction of the limiting groove 115. The cover plate 11 is provided with a number of sealing grooves 113, which are arranged one-to-one with the puncture holes 112 and are connected to the puncture holes 112. Each sealing groove 113 is connected to the inner wall of the puncture hole 112 by adhesive with a plastic bag 114. The plastic bag 114 is filled with adhesive liquid. When the needle 211 punctures the plastic bag 114, the adhesive liquid can flow out, thereby achieving the bonding between the needle 211 and the inner wall of the puncture hole 112, so that the sealing column 2 can be fixed.

[0038] Reference Figure 1 and Figure 2The inner wall of the sealing groove 113, which communicates with the puncture hole 112, is provided with a positioning groove 116. The positioning groove 116 is coaxially opened with the puncture hole 112 and is set in a constricted shape, so that more adhesive can be filled, so that more adhesive can participate in the connection between the needle 211 and the inner wall of the puncture hole 112, thereby improving the connection stability of the needle 211. Each sealing groove 113 has several seepage holes 117 on its inner wall, and the seepage holes 117 are all connected to the vacuum hole 111, so that some adhesive can enter the vacuum hole 111 through the seepage holes 117, thereby achieving direct bonding to the sealing column 2 and sealing the gap between the sealing column 2 and the vacuum hole 111, further improving the sealing performance of the plate body 1 of this application.

[0039] Reference Figure 1 and Figure 2 A limiting component 3 is provided inside the vacuum chamber 121. The limiting component 3 is connected to the sealing column 2 and causes the elastic element 122 to be in a compressed state. When the suction pipe of the suction device extends into the vacuum hole 111 and abuts against the sealing column 2, it will contact the limiting component 3 to restrict the sealing column 2. The limiting component 3 includes several limiting plates 31, several tension springs 32, several hanging plates 33, several first limiting rods 34 and second limiting rods 35. The limiting plates 31, tension springs 32, hanging plates 33 and first limiting rods 34 are arranged in a one-to-one correspondence.

[0040] Reference Figure 1 and Figure 2 The second limiting rod 35 is welded to the bottom wall of the vacuum chamber 121. The second limiting rod 35 is set vertically. The side wall of the limiting block 21 is integrally formed with a second limiting sleeve 212. The second limiting rod 35 is inserted into the second limiting sleeve 212, thereby limiting the movement trajectory of the limiting block 21, so that the sealing column 2 can accurately abut into the vacuum hole 111.

[0041] Reference Figure 1 and Figure 2Several limiting pieces 31 are welded to the bottom wall of the limiting block 21. One end of the tension spring 32 is glued to the inner wall of the vacuum chamber 121, and the other end is glued to a corresponding hanging piece 33. The first limiting rod 34 is welded to the inner wall of the vacuum chamber 121. The second limiting rod 35 is arranged parallel to the corresponding hanging piece 33. The side wall of the hanging piece 33 is integrally formed with a first limiting sleeve 331. The first limiting rod 34 is inserted into the corresponding first limiting sleeve 331, thereby enabling the hanging piece 33 to move horizontally. Movement; The limiting plate 31 has a through groove 311 for the hanging plate 33 to pass through along the thickness direction. One end of the hanging plate 33 passing through the through groove 311 is bent in the direction away from the vacuum hole 111. The bent part of the hanging plate 33 abuts against the inner wall of the limiting plate 31. When the suction pipe of the vacuuming device further compresses the elastic element 122, the bent part of the hanging plate 33 will lose contact with the limiting plate 31 and will disengage from the limiting plate 31 under the action of the tension spring 32, so that the sealing column 2 can be reset under the action of the elastic element 122.

[0042] Reference Figure 2 and Figure 3 A locking hole 118 is provided on the outer wall of the cover plate 11 away from the vacuum chamber 121. The locking hole 118 is coaxially opened with the vacuum hole 111. A locking ring 5 is welded into the locking hole 118. The diameter of the locking ring 5 is larger than the diameter of the vacuum hole 111. Several connecting holes 51 are provided through the locking ring 5 along the thickness direction. Several fixing holes 221 are provided on the peripheral wall of the sealing column 2 away from the elastic element 122 corresponding to the connecting holes 51. The fixing holes 221 are evenly distributed along the circumferential direction of the sealing column 2. A sliding groove 119 is provided on the surface of the cover plate 11 corresponding to the connecting holes 51. A locking pin 52 is slidably connected in each sliding groove 119. The locking pin 52 passes through the connecting hole 51 and is inserted into the fixing hole 221, thereby temporarily positioning the sealing column 2 so that the adhesive can have sufficient time to solidify and improve the stability of the connection of the sealing column 2.

[0043] Reference Figure 2 and Figure 3Each sliding groove 119 is provided with a locking element 6 for fixing the locking pin 52. The locking element 6 includes a ring cover 61 and several fixing plates 62. The fixing plates 62 are integrally formed on the side wall of the ring cover 61. Each fixing plate 62 corresponds to a sliding groove 119. The ring cover 61 covers the surface of the locking ring 5. The fixing plate 62 is embedded in the sliding groove. The bottom wall of the fixing plate 62 has a fixing groove 621 for the locking pin 52 to be embedded. After the locking pin 52 completes the positioning of the sealing post 2, it can lock the fixing groove 621 into the locking pin. The pin 52 is external to prevent the locking pin 52 from moving further; the end wall of the fixed plate 62 opposite to the ring cover 61 has a locking hole 622, and the bottom wall of the locking hole 622 is provided with a buffer spring 623 by adhesive. The other end of the buffer spring 623 is connected to the connecting post 624 by adhesive. The inner wall of the sliding groove has a connecting hole 1191 for the connecting post 624 to be inserted. When the connecting post 624 is inserted into the connecting hole 1191, the locking part 6 and the cover plate 11 can be fixed, thereby effectively improving the connection stability of the sealing post 2.

[0044] The implementation principle of an aluminum alloy heat insulation board incorporating heat insulation material in this application embodiment is as follows: After the board body 1 is manufactured, the air extraction pipe of the air extraction device is inserted into the vacuum hole 111 and abuts against the sealing column 2, so that the elastic element 122 can be further compressed. The sealing column 2 and the limiting piece 31 will move accordingly, so that the bent part of the hanging piece 33 loses the abutment of the limiting piece 31 and disengages from the hanging through groove 311 under the action of the tension spring 32.

[0045] After the air in the vacuum chamber 121 is evacuated, the sealing column 2 loses contact with the evacuation pipe of the evacuation device. Under the action of the elastic element 122, it will move towards the vacuum hole 111. The piercing needle 211 will pass through the piercing hole 112 and puncture the plastic bag 114 in the sealing groove 113, allowing the adhesive to flow out and bond the piercing needle 211 and the inner wall of the piercing hole 112. Another part of the adhesive will pass through the seepage hole 117 to achieve direct bonding to the sealing column 2. During the solidification process of the adhesive, the sealing column 2 can be positioned by the locking pin 52 and the locking element 6 until the adhesive is completely solidified. At this time, the heat insulation board body 1 with internal vacuum is completed, which improves the manufacturing convenience of the heat insulation board and the internal vacuum degree, so that the heat insulation board has better sealing performance.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
