Description

Technical Field

[0001] This utility model relates to the field of tile leveling equipment technology, and in particular to an automatic pressure relief structure for tile laying leveling equipment. Background Technology

[0002] Tile levelers are key auxiliary tools for tile laying. Their core function is to level and fix the tiles. They can offset the height differences caused by the warping of the tiles themselves and unevenness of the base layer, ensuring that the tile surface is flat and avoiding unevenness and gaps after laying. They can also prevent the tiles from shifting due to the flow of the adhesive layer, their own weight, or collisions during construction.

[0003] Because ceramic tiles have limited compressive strength, traditional ceramic tile levelers without pressure relief structures exert continuous clamping force on the uncured adhesive layer during use. This may cause the tiles to shift as the mortar shrinks, thus compromising the leveling effect. Pressure relief, on the other hand, releases pressure after the adhesive layer has initially cured, allowing the tiles to maintain their leveled position and form stably. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automatic pressure relief structure for a tile laying leveling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic pressure relief structure for a tile laying leveling device includes a main connecting rod, a leveling rod on the main connecting rod, and a support crossbar fixedly connected to the end of the leveling rod away from the main connecting rod. The leveling rod and the support crossbar are fixedly connected.

[0007] A sleeve is threaded onto the outer wall of the main connecting rod, and a buffer leveling seat is provided on the sleeve. The buffer leveling seat is parallel to the support crossbar.

[0008] The sleeve is provided with a buffer cylinder, the buffer leveling seat is provided with a sliding rod, the sliding rod is slidably disposed inside the buffer cylinder, and the buffer cylinder is provided with a buffer assembly.

[0009] Preferably, the buffer assembly includes a slide plate and a piston that are slidably disposed inside the buffer cylinder, an elastic element is provided between the slide plate and the piston, the slide plate is fixedly connected to a slide rod, and a sealed cavity is formed between the piston and the top inner wall of the buffer cylinder.

[0010] Furthermore, the sleeve is provided with a support base, the buffer cylinder is disposed on the support base, two rotating plates are provided between the support base and the sleeve, and the support base is provided with a pressure relief hole communicating with the buffer cylinder.

[0011] Furthermore, an annular sealing plate is fixedly installed inside the pressure relief hole, and a vertical rod is slidably connected inside the pressure relief hole. A sealing plate that cooperates with the annular sealing plate is provided on the vertical rod, and a locking nut is provided at the top of the vertical rod, which abuts against the outer wall of the support base.

[0012] Preferably, the main connecting rod is provided with a groove, and multiple sets of partitions are fixedly connected in the groove. The multiple sets of partitions divide the groove into multiple placement areas. A square plate is fixedly connected to the leveling rod, and the square plate is installed in the placement area.

[0013] Furthermore, the groove is filled with an installation block, the installation block has multiple slots corresponding to the partition, the installation block and the main connecting rod have corresponding threaded grooves, and the top of the main connecting rod has a knob.

[0014] Compared with the prior art, this utility model provides an automatic pressure relief structure for a tile laying leveling device, which has the following beneficial effects:

[0015] 1. This tile leveling device features an automatic pressure relief structure. Through its buffer cylinder and sliding rod, it provides a buffering effect when the leveling seat presses against the tile surface, preventing excessive pressure that could damage or chip the tile. After the leveling seat is fixed at one end for a period of time, allowing the inner adhesive layer of the tile to initially cure (usually 1-2 hours), and the mortar to gain some strength but not fully harden, pressure is released through the pressure relief hole. At this point, the tile is already bonded and fixed by the initially cured adhesive layer. Releasing pressure through the hole reduces the clamping force, preventing the tile from shifting. Furthermore, at this stage, the pressure relief only reduces the bonding pressure between the leveling seat and the tile; the leveling seat is not completely removed. It still provides a certain degree of leveling effect. Once the adhesive layer has fully cured and can self-fix the tile, the leveling device can be removed.

[0016] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model releases pressure after the adhesive layer has been initially cured, and at the same time has a supporting effect. After the adhesive layer can fix the tile itself, the leveling device can be removed, which can keep the tile in a stable position after leveling and make the tile flatter after bonding.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Reference Figures 1-7An automatic pressure relief structure for a tile leveling device includes a main connecting rod 1, a leveling rod 2 on the main connecting rod 1, a support crossbar 202 fixedly connected to the end of the leveling rod 2 away from the main connecting rod 1, and the leveling rod 2 and the support crossbar 202 being fixedly connected; a sleeve 3 is threadedly connected to the outer wall of the main connecting rod 1, a buffer leveling seat 4 is provided on the sleeve 3, the buffer leveling seat 4 is arranged parallel to the support crossbar 202; a buffer cylinder 303 is provided on the sleeve 3, a sliding rod 401 is provided on the buffer leveling seat 4, the sliding rod 401 is slidably disposed in the buffer cylinder 303, and a buffer assembly is provided in the buffer cylinder 303.

[0028] In this invention, during use, the leveling rod 2 and the support crossbar 202 are inserted through the gaps between the tiles. It should be noted that the leveling rod 2 and the support crossbar 202 are relatively thin, so they will not affect the normal tiling process. After insertion, the main connecting rod 1 is rotated 90 degrees so that the inserted support crossbar 202 abuts against the inner walls of the upper and lower tiles, thus achieving a limiting position. At this point, the main connecting rod 1 and the support crossbar 202 can be slid left and right to allow residual cement on the inner walls of the tiles to be removed via the support crossbar 202. To prevent the cement from hardening and locking the inserted support crossbar 202, thus facilitating its removal, the sleeve 3 is rotated to connect with the main connecting rod 1 via a thread and move along it. This moves the leveling seat 4, bringing it into contact with the outer surface of the tile. Rotating the sleeve 3 again adjusts the flatness of the two tiles under the action of the leveling seat 4 and the support crossbar 202, ensuring they are on the same plane. The buffer cylinder 303 and sliding rod 401 provide a buffering effect when the leveling seat 4 presses against the surface of the tile, preventing the tile from being crushed or chipped by forcefully rotating the sleeve 3 after the leveling seat 4 is in contact with the tile surface. After the leveling seat 4 is fixed at one end for a period of time, that is, after the adhesive layer of the inner layer of the tile has initially cured (usually 2-4 hours), and the mortar has gained some strength but is not completely hard, pressure is released through the pressure relief hole 304. At this time, the tile has been fixed by the initially cured adhesive layer. Releasing the pressure through the pressure relief hole 304 causes it to lose some clamping force, and the tile will not shift. At this time, the pressure relief hole 304 only reduces the bonding pressure between the leveling seat 4 and the tile, and does not completely remove the leveling seat 4. The leveling seat 4 can still achieve a certain leveling effect on the tile. Then, after the adhesive layer has completely cured and can fix the tile itself, the sleeve 3 is rotated in the opposite direction so that the leveling seat 4 no longer presses against the tile. The support crossbar 202 is rotated until it is parallel to the tile gap, and then it can be pulled out.

[0029] Currently, the adhesive layer is soft before it cures. If the leveling device is kept clamped, the tiles will be displaced by the continuous clamping force as the mortar dries and shrinks, causing the originally leveled position to become crooked. In this application, the pressure is released after the adhesive layer has initially cured, which also provides support. After the adhesive layer can fix the tiles on its own, the leveling device can be removed, allowing the tiles to maintain their stable leveled position and resulting in better flatness of the tiled surface.

[0030] Reference Figures 1-4 The buffer assembly includes a slide plate 402 and a piston 403 that are slidably disposed inside the buffer cylinder 303. An elastic element 404 is provided between the slide plate 402 and the piston 403. The slide plate 402 is fixedly connected to the slide rod 401. A sealed cavity is formed between the piston 403 and the top inner wall of the buffer cylinder 303.

[0031] Reference Figures 1-4 The sleeve 3 is provided with a support base 301, and the buffer cylinder 303 is provided on the support base 301. Two rotating plates 302 are provided between the support base 301 and the sleeve 3. The support base 301 is provided with a pressure relief hole 304 that communicates with the buffer cylinder 303.

[0032] In this invention, when the rotating sleeve 3 moves the leveling seat 4, the leveling seat 4 will compress the tile and ensure the flatness between the two tiles. At the same time, the sliding rod 401 will drive the sliding plate 402 to move and compress the elastic element 404, achieving a certain buffering effect. Simultaneously, it will drive the piston 403 to move inside the buffer cylinder 303, thereby compressing the sealing cavity. At this time, the gas inside the sealing cavity generates a certain pressure, which can support the piston 403, thereby supporting the leveling seat 4. This achieves a buffering effect during leveling and avoids damage to the tile.

[0033] Reference Figure 3 , Figure 4 and Figure 7 An annular sealing plate 5 is fixedly installed inside the pressure relief hole 304. A vertical rod 502 is slidably connected inside the pressure relief hole 304. A sealing plate 501 that cooperates with the annular sealing plate 5 is provided on the vertical rod 502. A locking nut 503 is provided at the top of the vertical rod 502. The locking nut 503 abuts against the outer wall of the support base 301.

[0034] In this invention, in the initial state, the sealing sheet 501 and the annular sealing plate 5 are in abutting state. The cooperation between the two will seal the pressure relief hole 304. At the same time, the locking nut 503 will fix the sealing effect. When pressure relief is needed, the locking nut 503 is loosened, allowing the vertical rod 502 to move, thereby separating the sealing sheet 501 from the annular sealing plate 5. At this time, the gas in the sealing cavity can be discharged through the pressure relief hole 304, which will cause the leveling seat 4 to produce a certain displacement, thereby achieving the pressure relief effect.

[0035] Reference Figure 5 and Figure 6 The main connecting rod 1 is provided with a groove 102, and multiple sets of partitions 103 are fixedly connected in the groove 102. The multiple sets of partitions 103 divide the groove 102 into multiple placement areas. A square plate 201 is fixedly connected to the leveling rod 2 and is installed in the placement area.

[0036] The groove 102 is filled with a mounting block 104. The mounting block 104 is provided with a plurality of slots 105 corresponding to the partition 103. The mounting block 104 and the main connecting rod 1 are provided with corresponding threaded grooves. The top of the main connecting rod 1 is provided with a knob 101.

[0037] In this utility model, during installation, the square plate 201 on the leveling rod 2 can be placed in different placement areas, thereby adjusting the distance between the supporting crossbar 202 and the leveling seat 4, making it suitable for use with tiles of different thicknesses. The mounting block 104 allows the square plate 201 and the leveling rod 2 to be easily fixed, and the mounting block 104 cooperates with the threaded groove on the main connecting rod 1 to ensure the threaded connection effect of the sleeve 3. After the sleeve 3 is threadedly connected, the mounting block 104 can be fixed simultaneously. The rotating plate 302 allows the sleeve 3 to be easily rotated, and the knob 101 allows the main connecting rod 1 to be easily rotated and removed.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
