[0026] refer to Figure 1 and Figure 2 The auxiliary device for pasting building material rolls onto the building surface includes a rod 10, an installation mechanism 20, a roller brush 30, and a leveling component 40.

[0027] The installation mechanism 20 is mounted on one end of the rod 10, and the roller brush 30 is rotatably mounted on the installation mechanism 20. The roller brush 30 can be dipped in adhesives such as epoxy resin. The leveling component 40 is mounted on the other end of the rod 10. The roller brush 30 remains attached to the building surface. By moving the auxiliary device for bonding building material rolls to the building surface, the roller brush 30 rolls, applying the dipped adhesive to the building surface so that the building material rolls can be bonded to the building surface using the adhesive. After the building material rolls are laid on the building surface, the auxiliary device for bonding building material rolls to the building surface is turned around so that the leveling component 40 remains attached to the building material rolls. By moving the auxiliary device for bonding building material rolls to the building surface, the leveling component 40 scrapes away air bubbles between the building material rolls and the building surface, improving the flatness of the building material roll surface and the firmness of the bond with the building surface.

[0028] It is understood that the auxiliary device for pasting building material rolls on building surfaces can be applied to the laying of building material rolls such as carbon fiber cloth, wall coverings, and wallpaper.

[0029] Preferably, the rod 10 includes a first fitting 11 and a second fitting 12, the first fitting 11 being telescopically inserted into the second fitting 12, and the leveling component 40 being installed at one end of the first fitting 11. By adjusting the degree of telescopic extension between the first fitting 11 and the second fitting 12, the support length of the first fitting 11 and the second fitting 12 can be adjusted, allowing the auxiliary device for pasting building material rolls on building surfaces to be applied to construction work on buildings of different heights.

The third mounting component 13 forms a plurality of second threaded holes 1301 spaced apart along its own axial direction, and the second mounting component 12 forms a second mounting hole 1203. When the second mounting hole 1203 is aligned with any of the second threaded holes 1301, the second rod portion of the second fixing member 52 passes through the second mounting hole 1203 and is threadedly installed in the second threaded hole 1301.

[0038] refer to Figure 2 and Figure 4 In another embodiment, the second fastener 52 forms a second mounting channel 5201, and an internal thread is formed on the inner wall of the second mounting channel 5201. The second fastener 52 is sleeved on the third mounting accessory 13. The second mounting accessory 12 has at least two spaced-apart second radial adjustment grooves 1204 at one end near the mounting mechanism 20, and an external thread is formed on the outer peripheral wall of the end of the second mounting accessory 12 forming the second radial adjustment grooves 1204. The end of the second mounting accessory 12 forming the second radial adjustment grooves 1204 can be threadedly mounted to the second mounting channel 5201 formed by the second fastener 52.

[0039] It is worth mentioning that the end of the second fitting 12 forming the second radial adjustment groove 1204 has a relaxed state and a tightened state. In the relaxed state, the second fitting 12 and the second fixing member 52 are separated, and the radial cross-sectional dimension of the end of the second fitting 12 forming the second radial adjustment groove 1204 gradually decreases from the direction in which the third fitting 13 is inserted into the second fitting 12. At this time, the third fitting 13 can move relative to the second fitting 12. In the tightened state, the second fixing member 52 is threaded onto the second fitting 12, the end of the second fitting 12 forming the second radial adjustment groove 1204 is restricted by the second fixing member 52 and retracts in the axial direction, and the inner wall of the second fitting 12 fits against the outer wall of the third fitting 13, thereby fixing the third fitting 13. In this embodiment, no alignment is required, improving the locking speed of the second fixing member 52.

[0040] Preferably, the auxiliary device for pasting building material rolls onto the building surface further includes an anti-slip sleeve 60, which is installed on the second assembly 12 to facilitate gripping by workers.

[0041] refer to Figure 5Preferably, the mounting mechanism 20 includes a mounting body 21 and two side mounting members 22, with one end of the rod 10 away from the leveling member 40 connected to the mounting body 21.

[0042] Furthermore, the mounting body 21 includes a first mounting portion 211 and a second mounting portion 212. The first mounting portion 211 is telescopically mounted on the second mounting portion 212, and the two side mounting members 22 are respectively mounted on the first mounting portion 211 and the second mounting portion 212. By adjusting the degree of telescopic extension between the first mounting portion 211 and the second mounting portion 212, the length of the mounting body 21 and the distance between the two side mounting members 22 can be adjusted, so that roller brushes 30 of different sizes can be assembled on the mounting mechanism 20.

[0043] In a preferred embodiment, the second mounting portion 212 forms a mounting groove 21201, the first mounting portion 211 is inserted into the mounting groove 21201, and the second mounting portion 212 forms the inner wall of the mounting groove 21201, defining the extension and retraction direction of the first mounting portion 211.

[0044] Preferably, the mounting mechanism 20 further includes an elastic element 23, which connects the first mounting portion 211 and the second mounting portion 212. The elastic element 23 elastically deforms when the roller brush 30 is mounted between the two side mounting members 22, and tends to pull the first mounting portion 211 and the second mounting portion 212 to contract, so that the two side mounting members 22 are driven by the elastic element 23 to maintain a tight fit with the roller brush 30.

[0045] As an example, the elastic element 23 is implemented as a spring.

[0046] Specifically, the mounting body 21 further includes two connectors 24, which are respectively mounted on opposite sides of the two side mounting pieces 22. The roller brush 30 forms an insertion channel 301, and the two connectors 24 are inserted into the insertion channel 301 through corresponding ports, so that the roller brush 30 can be detachably mounted between the two side mounting pieces 22 for easy replacement of the roller brush 30.

[0047] In some embodiments, the connector 24 is rotatably mounted to the side mount 22, and the connector 24 drives the roller brush 30 to rotate relative to the side mount 22. In other embodiments, the connector 24 is fixedly mounted to the side mount 22, and the roller brush 30 is rotatable relative to the connector 24.

[0048] In one embodiment, the leveling member 40 has at least one inclined surface 401 at one end away from the rod 10. The inclined surface 401 of the leveling member 40 is attached to the surface of the building material roll, thereby increasing the contact area between the leveling member 40 and the building material roll and improving the leveling and de-bubbling effect.

[0049] In a preferred embodiment, the leveling component 40 includes a mounting base 41 and a scraper 42. The mounting base 41 is mounted on the rod body 10, and the scraper 42 forms the inclined surface 401. The mounting base 41 forms a mounting groove 4101, and the scraper 42 is detachably mounted in the mounting groove 4101 to facilitate replacement of the scraper 42.

[0050] As an example, the scraper 42 is made of silicone material, which allows the scraper 42 to undergo elastic deformation to avoid scratching the building material roll.

[0051] Preferably, the mounting base 41 is threaded onto the rod body 10 to facilitate the replacement of the leveling component 40, allowing workers to replace the leveling component 40 with one that matches the width of the building material roll.

[0052] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented.
