Description

Technical Field

[0001] This utility model relates to the field of aerocondensed felt structure technology, specifically to a snap-fit ​​aerocondensed felt structure. Background Technology

[0002] Aerogel, as a novel functional material with a three-dimensional nanoporous structure, has attracted much attention due to its excellent properties such as extremely low thermal conductivity, high porosity, and low density. Among them, aerogel felt is a flexible thermal insulation material made by combining nano-silica as the main substrate with carbon fiber, ceramic glass fiber, or pre-oxidized fiber felt through special processes. It has a very broad application space in the field of thermal insulation and has been widely used in many fields such as construction, industrial pipelines, and new energy.

[0003] However, when aerogel felt is applied to building interior insulation projects, dust is easily shed during use due to the nanoscale pores and loose structure on the surface of the aerogel felt. This not only adversely affects the stability of the material's insulation performance but also pollutes indoor air. Long-term exposure to such an environment may pose potential health risks to the respiratory system. To address these issues, we propose a snap-fit ​​aerogel felt structure. Utility Model Content

[0004] The present invention aims to provide a snap-fit ​​aerogel felt structure to solve the problem that aerogel felt is prone to dust shedding during use, which not only adversely affects the stability of the material's thermal insulation performance but also pollutes indoor air.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a snap-fit ​​aerogel felt structure, comprising an insulation layer, a reinforcing mesh, and several snap-fit ​​components. The insulation layer comprises an aerogel felt, and the snap-fit ​​components comprise an expansion sleeve and a snap-fit ​​ring. The expansion sleeve is disposed on one side of the aerogel felt, and the snap-fit ​​ring is disposed on the side of the aerogel felt away from the expansion sleeve. A stepped groove is formed on the inner wall of the snap-fit ​​ring. Several snap heads are provided at the end of the expansion sleeve near the snap-fit ​​ring, and each snap head can penetrate the aerogel felt and snap into the stepped groove of the snap-fit ​​ring. The reinforcing mesh is wrapped around the insulation layer and the outer wall of the aerogel felt. The snap-fit ​​ring is disposed on the outer wall of the reinforcing mesh. The expansion sleeve is disposed at the end of the reinforcing mesh away from the snap-fit ​​ring, and the snap head at the end of the expansion sleeve penetrates the reinforcing mesh and the thickness-fixing member and snaps into the stepped groove of the snap-fit ​​ring.

[0006] The beneficial effects of this solution are as follows: by wrapping the outer wall of the reinforcing mesh with the wrapping layer, the aerogel felt and the snap-fit ​​components can be bound together as a whole, preventing the aerogel felt from shedding powder or breaking due to looseness. The woven structure of the reinforcing mesh has a certain degree of toughness and can expand and contract with the slight deformation of the insulation layer, which does not restrict the normal state of the aerogel felt and can improve the tear resistance of the overall structure. The installation of the snap-fit ​​components does not require complicated tools. Simply insert the snap head at one end of the expansion sleeve through the aerogel felt and engage it with the stepped groove of the snap-fit ​​ring on the other side to complete the fixation. The operation is simple and efficient, and the thickness of the aerogel felt structure can be kept consistent, which can significantly shorten the assembly time and is suitable for large-scale production or rapid on-site construction.

[0007] Preferably, as an improvement, the insulation layer further includes several thickness-fixing components, which are evenly arranged inside the aerogel felt. The height of the thickness-fixing components is less than the thickness of the aerogel felt. Each clamp can penetrate the thickness-fixing component and engage with the stepped groove of the clamping ring, thus compressing the aerogel felt to the same thickness.

[0008] The beneficial effects are as follows: the thickness-fixed component can provide a docking channel for the clamp head and the clamping ring. At the same time, the thickness-fixed component can also serve as an internal support structure, enhancing the insulation layer's resistance to deformation, improving its structural stability, and reducing the risk of breakage during use.

[0009] Preferably, as an improvement, the snap-fit ​​component also includes an expansion rod, and each snap-fit ​​head has a common threaded hole in the middle. The expansion rod can be threadedly connected to the threaded hole, and when the expansion rod is connected to the threaded hole, it can make each snap-fit ​​head move away from each other.

[0010] The beneficial effects are: during the installation process, the opening state of the clamp can be intuitively judged by observing the screw-in depth of the expansion rod or feeling the tightening resistance, thereby accurately controlling the tightness of the clamping and avoiding loose connection due to the clamp being too loose or clamp breakage due to being too tight, thus improving the controllability of installation quality.

[0011] Preferably, as an improvement, the reinforcing mesh is wrapped around the outer wall of the aerogel felt, the snap ring is disposed on the outer wall of the reinforcing mesh, the expansion sleeve is disposed at the end of the reinforcing mesh away from the snap ring, and the snap head at the end of the expansion sleeve passes through the reinforcing mesh and the thickness-fixing member and snaps into the stepped groove of the snap ring.

[0012] Preferably, as an improvement, it further includes several fixing components for connecting the aerosol felt structure to the wall. The fixing components include mounting blocks and insertion blocks. The mounting blocks are fixedly installed on the upper end of the wall. The mounting blocks have insertion slots. The insertion blocks are located on the outer wall of the snap ring and can be inserted into the insertion slots. The mounting blocks have sliding slots that communicate with the insertion slots. The sliding slots have abutment members. The insertion blocks have trigger slots. The trigger slots have trigger members that can cause the abutment members to push the insertion blocks, thereby making the insertion blocks fit tightly against the inner wall of the insertion slots.

[0013] The beneficial effects are as follows: To improve the installation efficiency of thermal insulation structures, existing technologies typically use an insert-type installation method to fix the thermal insulation structure to the wall. Compared with bolt fixing, this method significantly improves installation efficiency. However, because the insert-type installation method is prone to gaps between the insert block and the slot, the thermal insulation structure may wobble when installed on the wall, and the thermal insulation structure of an entire wall may be uneven due to the gaps in the insert-type installation. In this solution, when the insert block is inserted into the insertion slot of the installation block, the trigger and the abutment interact, causing the abutment to push the insert block, making the insert block fit tightly against the inner wall of the insertion slot. This eliminates the gap between the insert block and the insertion slot, greatly improving the connection strength between the thermal insulation structure and the wall, effectively preventing loosening or displacement caused by external forces, ensuring that the thermal insulation structure is stably fixed to the wall for a long time. Furthermore, when the insert block fits against the inner wall of the insertion slot, the thermal insulation structure remains parallel to the wall surface, thus avoiding angular deviations between adjacent thermal insulation structures and improving the flatness of the thermal insulation structure during installation.

[0014] Preferably, as an improvement, the abutting component includes a support rod, an abutting block, a lifting block, and two first wedge blocks and a second wedge block. The support rod is located at the end of the sliding groove away from the insertion groove. A reset cavity is formed inside the abutting block. One end of the support rod passes through the abutting block and extends into the reset cavity. A limiting block is provided at the end of the support rod extending into the reset cavity. A first spring is sleeved on the outer wall of the support rod, and the first spring is located between the limiting block and the reset cavity. Two first wedge blocks are symmetrically arranged at the end of the abutting block near the support rod. The mounting block has a lifting groove that communicates with the sliding groove. The lifting block is slidably installed in the lifting groove. Two second wedge blocks are symmetrically arranged at the lower end of the lifting block, and the second wedge blocks abut against the first wedge blocks. When the second wedge blocks move downward, the first wedge blocks push the abutting block to extend into the insertion groove and abut against the insertion block.

[0015] The beneficial effects are as follows: the support rod passes through the abutment block and limits the displacement range of the abutment block through the limiting block, providing stable guiding support for the abutment block and preventing the abutment block from tilting or bending when under force. The two second wedge blocks abut symmetrically with the first wedge block. When the lifting block moves downward, the inclined surface of the second wedge block squeezes the first wedge block, converting the vertical driving force into the horizontal thrust, pushing the abutment block to accurately extend into the insertion slot and abut tightly with the insertion block, thereby eliminating the gap between the insertion block and the insertion slot, greatly improving the connection strength between the insulation structure and the wall, and effectively preventing loosening or displacement caused by external forces.

[0016] Preferably, as an improvement, the triggering component includes a connecting plate, a trigger plate, and a pin. The connecting plate is slidably installed in the trigger groove. Several second springs are provided between the upper end of the connecting plate and the upper wall of the trigger groove. The lower end of the insertion block has a through groove that communicates with the trigger groove. The trigger plate is located at the lower end of the connecting plate and can extend out of the through groove to contact the lifting block. The lower end of the insertion block has a locking groove that communicates with the through groove. The pin is slidably installed in the locking groove. The lower end of the pin has a trapezoidal block. The upper end of the mounting block has a shaped groove that matches the trapezoidal block.

[0017] The beneficial effects are as follows: when the insert block is inserted into the insertion slot of the mounting block, the trapezoidal block at the lower end of the pin moves down with the insert block and contacts the inclined surface of the irregular groove. At this time, the pin slides along the inclined surface of the irregular groove. When the insert block is fully inserted into the insertion slot, the pin separates from the trigger plate, and then the trigger plate extends out of the through slot and contacts the lifting block under the action of several second springs. The lifting block slides down along the lifting groove, and then the action of the second wedge block and the first wedge block drives the abutment block to extend and press against the insert block.

[0018] Preferably, as an improvement, the first wedge block has a guide block at one end near the second wedge block, and the second wedge block has a guide groove at one end near the first wedge block that matches the guide block.

[0019] The beneficial effect is that after the guide block is embedded in the guide groove, it can limit the relative offset between the first wedge block and the second wedge block in the horizontal and vertical directions, ensuring that the first wedge block and the second wedge block only slide relative to each other along the inclined plane direction.

[0022] Example 1 Example 1 is basically as shown in the appendix. Figures 1-2 As shown, Figure 1 The diagram illustrates a snap-fit ​​aerogel felt structure, comprising an insulation layer, a reinforcing mesh 3, and several snap-fit ​​components. The insulation layer includes an aerogel felt 2 and several thickness-fixed components 4. The thickness of the aerogel felt 2 is set to 10-25mm. The aerogel felt 2 can also be replaced with materials such as cement-based aerogel insulation board or inorganic foamed aerogel insulation board. Several holes are formed in the outer wall of the aerogel felt 2, and the thickness-fixed components 4 are fixedly installed inside the aerogel felt 2 through these holes. The horizontal and vertical spacing of each thickness-fixed component 4 is set to 100-600mm. The thickness-fixed components 4 are tubular, with a channel in the middle, and the height of the thickness-fixed components 4 is less than [missing information]. The thickness of the aerogel felt 2 is determined by the locking mechanism, which includes an expansion sleeve 6 and a locking ring 7. The expansion sleeve 6 is located on the left side of the aerogel felt 2, and the locking ring 7 is located on the right side of the aerogel felt 2. The inner wall of the locking ring 7 has a stepped groove 8. The right end of the expansion rod 10 is integrally formed with several locking heads 9. In this embodiment, there are four locking heads 9, and each locking head 9 can be locked with the stepped groove 8 of the locking ring 7 through the channel in the middle of the thickness-fixing member 4. The locking mechanism also includes the expansion rod 10. The middle of each locking head 9 is provided with a threaded hole. The expansion rod 10 can be threadedly connected to the threaded hole, and when the expansion rod 10 is connected to the threaded hole, it can keep the locking heads 9 away from each other. Figure 2 The expansion rod 10 shown has a cross groove 11 at its end. By rotating the expansion rod 10 with a screwdriver, each clip 9 and the snap ring 7 are tightened, preventing the clip 9 from falling off. In this embodiment, the aerogel felt structure can be directly pasted to the wall with cement mortar, which greatly improves the installation efficiency of the aerogel felt structure. The reinforcing mesh 3 is wrapped around the insulation layer and the outer wall of the snap ring. The thickness of the reinforcing mesh 3 is set to 0.5-15mm. Of course, the reinforcing mesh 3 can also be set as a bag with an opening. The aerogel felt 2 is put into the bag-shaped reinforcing mesh 3, and then the opening of the reinforcing mesh 3 is sealed with yarn, thereby sealing the aerogel felt 2 inside the reinforcing mesh 3. The reinforcing mesh 3 can be set as an alkali-resistant glass fiber breathable membrane, such as... Figure 1The outer wall of the reinforcing mesh 3 shown is coated with cement mortar or organic adhesive to form a wrapping layer 1. The organic adhesive is set as polyurethane adhesive, epoxy resin adhesive, etc. The thickness of the wrapping layer 1 is set to 0.5-1.5mm. Of course, an air-barrier membrane can also be used to wrap the outer wall of the reinforcing mesh 3. The air-barrier membrane can be set as a building waterproof and breathable membrane, geotextile, alkali-resistant fiberglass reinforced mesh composite geotextile, skeleton non-woven fabric, polyester fiber felt, PVC fiberglass coated felt, cement fiberglass coated felt, etc. The wrapping layer 1 can serve as a rigid support for the insulation layer, protecting the reinforcing mesh 3 and preventing the reinforcing mesh 3 from being torn and exposing the insulation layer.

[0023] The specific implementation process is as follows: By wrapping the insulation layer 1 around the outer wall of the snap-fit ​​component, the aerogel felt 2, the thickness gauge 4, and the snap-fit ​​component can be bound together as a whole, preventing the aerogel felt 2 from shedding powder or breaking due to looseness. The woven structure of the reinforcing mesh 3 has a certain degree of toughness and can expand and contract with the slight deformation of the insulation layer, which does not restrict the normal state of the aerogel felt 2 and can improve the tear resistance of the overall structure. The thickness gauge 4 can provide a docking channel for the snap head 9 and the snap-fit ​​ring 7. At the same time, the thickness gauge 4 can also serve as an internal support structure, enhancing the insulation layer's resistance to deformation, improving its structural stability, and reducing the risk of damage during use. The installation of the snap-fit ​​component does not require complicated tools. Simply insert the snap head 9 at one end of the expansion sleeve 6 through the thickness gauge 4 and engage it with the stepped groove 8 of the snap-fit ​​ring 7 on the other side to complete the fixation. The operation is simple and efficient, and the thickness of the aerogel felt structure can be kept consistent, which can significantly shorten the assembly time and is suitable for large-scale production or rapid on-site construction.

[0024] Example 2 Example 2 is largely the same in principle as Example 1, the difference being: Figure 3 The reinforcing mesh 3 shown is wrapped around the outer wall of the aerogel felt 2. The snap ring 7 is located at the right end of the reinforcing mesh 3, and the expansion sleeve 6 is located at the left end of the reinforcing mesh 3. The ends of the expansion sleeve 6 and the snap ring 7 protrude completely from the outer wall of the reinforcing mesh 3 or are partially embedded in the outer wall of the reinforcing mesh 3. The snap head 9 at the end of the expansion sleeve 6 passes through the reinforcing mesh 3 and the thickness fixing member 4 and snaps into the stepped groove 8 of the snap ring 7. By passing the snap member through the reinforcing mesh 3 and the thickness fixing member 4, the aerogel felt 2 can be fixed in a specific position of the reinforcing mesh 3 to prevent the aerogel felt 2 from shifting or piling up in the reinforcing mesh 3. The insulation layer and the wrapping layer 1 are both provided with several fixing holes 5, and each thickness fixing member 4 is respectively located in the corresponding fixing hole 5. Both ends of the fixing hole 5 are countersunk holes.

[0025] Example 3 Example 3 is largely the same in principle as Example 2, the difference being: Figure 4As shown, it also includes several fixing components that connect the aerocondensed felt insulation structure to the wall. The fixing components include mounting blocks 12 and insertion blocks 13. The mounting blocks 12 are fixedly installed to the upper end of the wall by welding or expansion screws, as shown. Figure 5 The mounting block 12 shown has an insertion groove 14. The insertion block 13 is fixedly installed on the outer wall of the wrapping layer. The lower end of the insertion block 13 can be inserted into the insertion groove 14. The right end of the mounting block 12 has a sliding groove 15 that communicates with the insertion groove 14. The sliding groove 15 has an abutment, which includes a support rod 16, an abutment block 17, a lifting block 18, and two first wedge blocks 19 and a second wedge block 20. The support rod 16 is fixedly installed on the right wall of the sliding groove 15, and the abutment block 17... A reset cavity 21 is provided at the right end. The reset cavity 21 is cylindrical. The left end of the support rod 16 extends into the reset cavity 21 through the abutment block 17. A limit block 22 is fixedly installed at the left end of the support rod 16. The limit block 22 is cylindrical and matches the reset cavity 21. A first spring 23 is sleeved on the outer wall of the support rod 16. The left end of the first spring 23 is fixedly connected to the limit block 22, and the right end of the first spring 23 is fixedly connected to the inner wall of the reset cavity 21. Two first wedges... Block 19 is symmetrically fixedly installed on the right end of abutment block 17. A lifting groove 24 communicating with sliding groove 15 is provided on the upper end of mounting block 12. Sliding grooves 25 are symmetrically provided on the front and rear inner walls of the lifting groove 24. Lifting block 18 is slidably installed between the two sliding grooves 25. Two second wedge blocks 20 are symmetrically fixedly installed on the lower end of lifting block 18, and the second wedge blocks 20 abut against the first wedge block 19. When the second wedge block 20 moves downward, the first wedge block 19 pushes abutment block 17. 7. The first wedge block 19 is inserted into the insertion groove 14 and abuts against the insertion block 13. A guide block 26 is fixedly installed on the right end of the first wedge block 19. The guide block 26 is set as a semi-cylindrical shape. The left end of the second wedge block 20 is provided with a guide groove 27 that matches the guide block 26. After the guide block 26 is embedded in the guide groove 27, it can limit the relative offset of the first wedge block 19 and the second wedge block 20 in the horizontal and vertical directions, ensuring that the first wedge block 19 and the second wedge block 20 only slide relative to each other along the inclined plane direction.

[0026] like Figure 6The insertion block 13 shown has a trigger groove 28 inside, and a trigger element is provided in the trigger groove 28. The trigger element can cause the abutment to push the insertion block 13, thereby making the insertion block 13 fit tightly against the inner wall of the insertion groove 14. The trigger element includes a connecting plate 29, a trigger plate 30, and a pin 31. The connecting plate 29 is slidably installed in the trigger groove 28. Several second springs 32 are fixedly installed between the upper end of the connecting plate 29 and the upper wall of the trigger groove 28. The lower end of the insertion block 13 has a connection to the trigger groove 28. The through slot 33, the trigger plate 30 is fixedly installed at the lower end of the connecting plate 29, and the trigger plate 30 can extend out of the through slot 33 and abut against the lifting block 18. The lower end of the insertion block 13 is provided with a locking groove 34 that communicates with the through slot 33. The pin 31 is slidably installed in the locking groove 34. A trapezoidal block 35 is fixedly installed on the lower right side of the pin 31. As shown in the figure, the upper end of the mounting block 12 is provided with a special groove 36 that matches the trapezoidal block 35. The inclined surface of the trapezoidal block 35 is tangent to the inclined surface of the special groove 36.

[0027] To improve the installation efficiency of thermal insulation structures, existing technologies typically employ an insert-type installation method to fix the insulation structure to the wall. This method significantly improves installation efficiency compared to bolt fixing. However, the insert-type installation method is prone to gaps between the insert block and the slot, causing the insulation structure to wobble when installed on the wall, and resulting in unevenness of the insulation structure across the entire wall due to the gaps. In this solution, when the insert block 13 is inserted into the insertion slot 14 of the mounting block 12, the trapezoidal block 35 at the lower end of the pin 31 moves down with the insert block 13 and contacts the inclined surface of the irregular groove 36. At this time, the pin 31 moves along the inclined surface of the irregular groove 36. When sliding occurs, when the insertion block 13 is fully inserted into the insertion slot 14, the pin 31 separates from the trigger plate 30, and the trigger plate 30 extends out of the through slot 33 under the action of several second springs 32 and contacts the lifting block 18, and the lifting block 18 slides down along the lifting slot 24, so that the inclined surface of the second wedge block 20 presses the first wedge block 19, converting the vertical driving force into the horizontal thrust, pushing the abutment block 17 to accurately extend into the insertion slot 14 and tightly abut against the insertion block 13, thereby eliminating the gap between the insertion block 13 and the insertion slot 14, greatly improving the connection strength between the insulation structure and the wall, and effectively preventing loosening or displacement caused by external forces.

[0028] When the insertion block 13 is inserted into the insertion slot 14 of the mounting block 12, the trigger and the abutment interact, causing the abutment to push the insertion block 13, making the insertion block 13 fit tightly against the inner wall of the insertion slot 14. This eliminates the gap between the insertion block 13 and the insertion slot 14, significantly improving the connection strength between the insulation structure and the wall. It effectively prevents loosening or displacement caused by external forces, ensuring that the insulation structure is stably fixed to the wall for a long time. Furthermore, when the insertion block 13 fits against the inner wall of the insertion slot 14, the insulation structure remains parallel to the wall surface, thus avoiding angular deviations between adjacent insulation structures and improving the flatness of the insulation structure during installation.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
