Description

Technical Field

[0001] This application relates to the field of plastering tools, and in particular to a plastering auxiliary device with controllable thickness. Background Technology

[0002] In architectural decoration construction, the laying of stone or tiles on walls and floors is a common construction step. To ensure the quality of the laying, it is usually necessary to apply a uniform layer of slurry or adhesive to the base surface.

[0003] When applying grout directly with a scraper, first pour the grout onto the surface, then repeatedly scrape it with the scraper to distribute it evenly. Another common method is to use a simple grouting tool, such as a straight scraper with a certain width, and spread the grout on the flat surface by pushing the scraper. Both methods require the operator to rely on experience and feel to control the thickness and evenness of the grout application, which can easily lead to uneven surfaces or hollow spots, affecting the construction quality and aesthetics. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a scraping auxiliary device with controllable thickness.

[0005] A thickness-controllable slurry scraping auxiliary device, comprising: The container has a discharge port on its bottom surface, and a scraper baffle is formed on the bottom surface of the container. The discharge device includes a telescopic base plate and a moving rod. The telescopic base plate is slidably disposed on the bottom surface of the container, and its upper surface abuts against the opening of the discharge port to control the opening degree of the discharge port. The moving rod is fixed to the telescopic base plate.

[0006] By adopting the above scheme, the size of the discharge port can be controlled by the moving rod and the telescopic base plate, thereby controlling the discharge volume of the container. During use, the telescopic base plate is used to compact the mortar. While pushing the mortar, the scraper baffle limits the bottom surface of the container, thereby controlling the thickness of the mortar to remain within the preset thickness range and avoiding hollow or uneven coating.

[0007] In one embodiment, the container includes four side plates and a fixed base plate fixed to the bottom of the side plates. The fixed base plate is slidably connected to the upper surface of the telescopic base plate. Fixed plates are fixed on both sides of the container. Each fixed plate has a horizontal handle on the side facing the container. The horizontal handle is higher than the upper surface of the container.

[0008] By adopting the above solution, in actual use, the horizontal handles are used to hold the scraping auxiliary equipment, and the operator holds the two horizontal handles to operate the scraping auxiliary equipment.

[0009] In one embodiment, the discharge device further includes a linkage assembly, with one end of each movable rod away from the telescopic base plate connected to the linkage assembly. The linkage assembly includes a drive linkage, a rotating linkage, and a support rod. The support rod is located between the drive linkage and the movable rod and is fixed to one side of the container. The drive linkage passes perpendicularly through the fixed plate on one side of the container and is fixed to the transverse handle. The middle part of the rotating linkage is rotatably connected to the support rod, and both ends are rotatably connected to the movable rod and the drive linkage, respectively.

[0010] By adopting the above scheme, when both horizontal handles are gripped simultaneously, the horizontal handle on one side of the container causes the drive linkage to move, which in turn causes the rotating linkage to rotate around the support center. The end of the rotating linkage that is away from the drive linkage causes the moving rod to move, which in turn causes the telescopic base plate to move, thereby controlling the size of the discharge port.

[0011] In one embodiment, the rotating connecting rod has a sliding groove in the middle, the extended end of the support rod has a sliding pin passing through the sliding groove, and a pull rod is provided between the moving rod and the rotating connecting rod, with both ends of the pull rod rotatably connected to the moving rod and the rotating connecting rod respectively.

[0012] By adopting the above scheme, since the rotation trajectory of the rotating link around the extended end of the support rod is the center, it will cause the moving rod and the driving link to have vertical displacement. The sliding groove can compensate for the vertical displacement of the driving link, and the pull rod can compensate for the vertical displacement of the moving rod, thus preventing interference between the link assembly and the container and the fixed plate during the movement.

[0013] In one embodiment, the telescopic base plate has an L-shaped cross-section, and a return spring is sleeved on the outer periphery of the moving rod. The two ends of the return spring abut against the inner wall of the container and the side of the telescopic base plate, respectively.

[0014] By adopting the above scheme, when both horizontal handles are gripped at the same time, the return spring is in a compressed state and generates a restoring force. When the two horizontal handles are released, the moving rod pushes the telescopic base plate to block the discharge port under the action of the restoring force.

[0015] In one embodiment, the container is provided with a cover plate on top, the cover plate being slidable along the height direction of the container.

[0016] By adopting the above scheme, when the scraping auxiliary equipment is working on a vertical wall, the cover plate seals the top of the container to prevent material leakage, and the material inside the container can be squeezed out when the cover plate slides along the height of the container.

[0017] In one embodiment, the upper surface of the cover plate is provided with a pressing rod, which is located between the two transverse handles.

[0018] By adopting the above scheme, when the scraping auxiliary equipment is working on a vertical wall, the operator can press the pressing rod on the upper surface of the cover plate with their thumb while holding the two horizontal handles at the same time, thereby moving the cover plate and squeezing out the material in the container.

[0019] In one embodiment, the inner wall surfaces at both ends of the container are respectively provided with mounting grooves, the two ends of the scraper baffle are respectively embedded in the mounting grooves, the mounting grooves are provided with racks, and the sides of the scraper baffle are provided with locking teeth that cooperate with the racks.

[0020] By adopting the above scheme, the clamping teeth can be clamped at any position on the rack, thereby controlling the distance by which the scraper baffle protrudes from the bottom surface of the container, thus enabling the scraper baffle to control mortar of different thicknesses.

[0021] In one embodiment, the scraper baffle is serrated on the side near the telescopic base plate.

[0022] By adopting the above solution, when the scraper baffle limits the container, it will rub against the mortar covering surface. By setting the side of the telescopic plate close to the telescopic base plate into a serrated shape, the contact area between the scraper baffle and the mortar covering surface is reduced, thereby reducing the friction.

[0023] In one embodiment, the fixed base plate extends downwards from the inner wall of the container.

[0024] By adopting the above scheme, when the scraping auxiliary equipment is working on a horizontal plane, the material in the container can flow towards the discharge port under the action of gravity.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The size of the discharge port can be controlled by the moving rod and the telescopic base plate, thereby controlling the discharge volume of the container. During use, the telescopic base plate is used to compact the mortar. While pushing the mortar, the scraper baffle limits the bottom surface of the container, thereby controlling the thickness of the mortar to remain within the preset thickness range and avoiding hollow or uneven coating.

[0026] 2. When the scraping auxiliary equipment is working on a vertical wall, the cover plate seals the top of the container to prevent material leakage. When the scraping auxiliary equipment is working on a vertical wall, the operator can hold both horizontal handles at the same time and press the pressing rod on the upper surface of the cover plate with their thumb, thereby moving the cover plate and squeezing out the material in the container. This allows the operator to control the material extrusion with one hand.

[0027] 3. By setting a rack in the installation groove and setting locking teeth on both sides of the scraper baffle to cooperate with the rack, the locking teeth can be locked at any position of the rack, thereby controlling the distance of the scraper baffle protruding from the bottom surface of the container, so that the scraper baffle can control the mortar of different thicknesses.

[0035] Therefore, it is necessary to provide a secondary structural system wall construction that can control the mortar thickness.

[0036] Please see Figure 1-3 , Figure 1 This is a structural schematic diagram of a thickness-controllable slurry scraping auxiliary device provided in this application. The thickness-controllable slurry scraping auxiliary device provided in this application includes a container 1 and a discharge device 2, wherein the container 1 and the discharge device 2 cooperate with each other. The discharge device 2 can control the size of the discharge port 13 of the container 1, thereby controlling the discharge amount of the container 1. When pushing the mortar, the scraper baffle 11 limits the bottom surface of the container 1 to keep the mortar at a preset thickness and avoid the scraped coating layer from being hollow or uneven.

[0037] Container 1 includes a scraper baffle 11 and a fixed base plate 12. The scraper baffle 11 is fixed to the inner wall of container 1 and protrudes from the bottom surface of container 1. The scraper baffle 11 is generally made of a hard and smooth material, such as stainless steel or hard plastic, to ensure that it is not easily worn during the scraping process and has low resistance to mortar. The scraper baffle 11 can be a rectangular plate structure for easy installation and adjustment. In some special cases, a trapezoidal or other shaped scraper baffle 11 can also be used to adapt to different mortar scraping requirements. In this application, the side of the scraper baffle 11 near the telescopic base plate 21 is set in a sawtooth shape. When the scraper baffle 11 limits the container 1, it will rub against the mortar covering surface. Setting the side of the scraper baffle 11 near the telescopic base plate 21 in a sawtooth shape can reduce the contact area between the scraper baffle 11 and the mortar covering surface, thereby reducing the friction.

[0038] The fixed base plate 12 is fixed to the inner wall of one side of the container 1, and the one side of the fixed base plate 12 forms a discharge port 13 with the inner wall of the container 1. The fixed base plate 12 is made of a metal with certain strength and wear resistance, such as aluminum alloy, so as to better withstand the pressure and friction of the mortar. The fixed base plate 12 is generally flat in shape. One side of the fixed base plate 12 is welded to the inner wall of the container 1 and extends downward from the inner wall of the container 1. When the mortar scraping auxiliary equipment is working on a horizontal plane, the material in the container 1 can flow to the location of the discharge port 13 under the action of gravity. The mortar scraping baffle 11 and the fixed base plate 12 are fixed to the inner wall of the container 1 by welding or bolt connection.

[0039] Please refer to the following: Figure 4 , Figure 4 yes Figure 3 The enlarged view of area B shows that the discharge device 2 includes a telescopic base plate 21, multiple moving rods 22, and a connecting rod assembly 23. The telescopic base plate 21 is located on the bottom surface of the container 1, and its upper surface abuts against the fixed base plate 12. The telescopic base plate 21 is typically made of high-strength plastic or thin steel plate to ensure sufficient strength to push the mortar. In this application, there are two moving rods 22, which are generally made of metal rods with good rigidity, such as carbon steel rods. The moving rods 22 are fixed to one side of the telescopic base plate 21, and a return spring 221 is sleeved on its outer circumference. The two ends of the return spring 221 abut against the inner wall surface of the container 1 and the side surface of the telescopic base plate 21, respectively. The cross-section of the telescopic base plate 21 is L-shaped to ensure sufficient area for abutment against the return spring 221. One side of the telescopic base plate 21 is fixed to the moving rod 22, and the two can be fixed by welding or threaded connection to ensure the stability of the connection. The moving rod 22 is controlled to extend or retract within the container 1 via the connecting rod assembly 23. When the moving rod 22 extends, the telescopic bottom plate 21 blocks the discharge port 13; when the moving rod 22 retracts, the telescopic bottom plate 21 exposes the discharge port 13.

[0040] In this application, fixing plates 14 are fixed to both sides of the container 1. The fixing plates 14 can be made of the same material as the container 1, such as metal sheet, and are fixed to both sides of the container 1 by welding or bolts. Each fixing plate 14 has a horizontal handle 15 on the side facing the container 1. The horizontal handle 15 is higher than the upper surface of the container 1 and is usually made of a rubber-coated metal rod, which is convenient to grip and increases friction. In actual use, the horizontal handle 15 is used to hold the scraping auxiliary equipment. The operator holds the two horizontal handles 15 to operate the scraping auxiliary equipment.

[0041] Each movable rod 22 is connected to a linkage assembly 23 at one end away from the telescopic base plate 21. The linkage assembly 23 includes a drive linkage 231, a rotating linkage 232, and a support rod 233. The support rod 233 is located between the drive linkage 231 and the movable rod 22 and is fixed to one side of the container 1, generally by welding or bolting. The drive linkage 231 passes perpendicularly through the fixed plate 14 on one side of the container 1 and is fixed to the transverse handle 15. The transverse handle 15 is located between two adjacent drive linkages 231, and they can be fixed together by threaded connection or welding. The rotating linkage 232 is rotatably connected to the support rod 233 in the middle and rotatably connected to the movable rod 22 and the drive linkage 231 at both ends, respectively.

[0042] The rotating connecting rod 232 has a sliding groove 2321 in the middle, and the extended end of the support rod 233 has a sliding pin 2322 that passes through the sliding groove 2321. This cooperation between the sliding groove 2321 and the sliding pin 2322 makes the rotating connecting rod 232 more flexible during rotation and can compensate for the vertical displacement of the driving connecting rod 231. A tie rod 234 is provided between the moving rod 22 and the rotating connecting rod 232. The two ends of the tie rod 234 are rotatably connected to the moving rod 22 and the rotating connecting rod 232, respectively. The tie rod 234 can compensate for the vertical displacement of the moving rod 22 and prevent interference between the connecting rod assembly 23 and the container 1 and the fixed plate 14 during movement.

[0043] When the operator simultaneously grips both horizontal handles 15, the horizontal handle 15 on one side of container 1 causes the drive linkage 231 to shift, which in turn causes the rotating linkage 232 to rotate. The end of the rotating linkage 232 that is away from the drive linkage 231 causes the moving rod 22 to move, which in turn causes the telescopic base plate 21 to move, thereby controlling the size of the discharge port 13. At this time, the return spring 221 is in a compressed state, generating a restoring force. When the operator releases the horizontal handle 15, the moving rod 22, under the action of the restoring force, pushes the telescopic base plate 21 to block the discharge port 13, thereby controlling the discharge amount of container 1.

[0044] The top of container 1 is equipped with a cover plate 16, which can slide along the height of container 1. The cover plate 16 is generally made of lightweight plastic with good sealing performance, which can reduce the weight of the equipment and prevent material leakage. A pressing rod 161 is provided on the upper surface of the cover plate 16, which is located between two horizontal handles 15. When the scraping auxiliary equipment is working on a vertical wall, when the operator holds both horizontal handles 15 at the same time, his thumb can press the pressing rod 161 on the upper surface of the cover plate 16, thereby moving the cover plate 16 and squeezing out the material in container 1.

[0045] Please refer to the following: Figure 5-6 , Figure 6 This is a cross-sectional view of the connection between the scraper baffle and the mounting groove. Mounting grooves 17 are respectively provided on the inner walls of both ends of the container 1. The two ends of the scraper baffle 11 are respectively embedded in the mounting grooves 17. A rack 171 is provided within each mounting groove 17. Clamping teeth 1111 that cooperate with the rack 171 are provided on both sides of the scraper baffle 11. Through the cooperation of the clamping teeth 1111 and the rack 171, the clamping teeth 1111 can be engaged at any position on the rack 171, thereby controlling the distance by which the scraper baffle 11 protrudes from the bottom surface of the container 1, thus enabling the scraper baffle 11 to control mortar of different thicknesses.

[0046] The working principle of this application is as follows: When the operator grips the two horizontal handles 15, the horizontal handle 15 located on one side of the container 1 drives the drive rod 231 to move, the drive rod 231 drives the rotating rod 232 to rotate, and the end of the rotating rod 232 away from the drive rod 231 drives the moving rod 22 to move, and the moving rod 22 drives the telescopic base plate 21 to move, thereby exposing the discharge port 13. When the operator releases the two horizontal handles 15, the moving rod 22 returns to its original position under the restoring force of the return spring 221, thereby blocking the discharge port 13.

[0047] Before using the mortar scraping auxiliary equipment, first grip the two horizontal handles 15. The connecting rod assembly 23 will drive the moving rod 22 to pull the telescopic base plate 21, opening the discharge port 13. Then, immerse the mortar scraping auxiliary equipment in the mortar, allowing the mortar to flow from the discharge port 13 into the container 1 until it is full. Next, release the horizontal handles 15, causing the telescopic base plate 21 to seal the discharge port 13. Alternatively, workers can directly feed mortar into the container 1 through the opening until it is full.

[0048] During the mortar scraping operation, the operator can control the opening size of the discharge port 13 by gripping the two horizontal handles 15, thereby controlling the discharge amount of container 1. The scraper baffle 11 abuts against the mortar covering surface, thereby creating a gap between the bottom surface of container 1 and the mortar covering surface. The size of the gap is the thickness of the mortar. The operator can control the extension length of the scraper baffle 11 by cooperating with the rack 171 and the clamping teeth 1111, thereby changing the thickness of the mortar that needs to be controlled. The telescopic base plate 21 abuts against the mortar, thereby compacting the mortar.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
