Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary ceramic tile laying, and specifically relates to a folding avoidance structure for a suction cup frame of a ceramic tile laying device. Background Art

[0002] At present, the laying of wall ceramic tiles in building construction and house decoration is mostly limited to manual laying. Especially for large-sized ceramic slabs with large area and heavy weight, high requirements are imposed on the number of constructors and the technical experience of personnel. Accordingly, ceramic tile auxiliary laying devices that can assist personnel in their work have appeared on the market.

[0003] In order to carry out stable laying work for large-area ceramic rock slabs, the suction cup frame used in the ceramic tile laying device correspondingly has a relatively large volume. However, when the ceramic tile laying device needs to pass through narrow spaces such as door frames and elevators, and during loading and transportation, the large suction cup frame will adversely affect the trafficability, and occupies a large space during loading, which is not conducive to loading and transportation. If the suction cup frame is disassembled separately, the operation will be inconvenient, especially repeated disassembly and assembly in a complex construction site will greatly affect the construction efficiency.

[0004] For example, a construction auxiliary tool for thin-layer laying of large ceramic slabs with the publication number CN2转轴157第一锁定头16995U describes that the suction cup frame comprises two parallel X-direction square pipes, two parallel Y-direction square pipes, and four telescopic pipes with a "day"-shaped cross section. The two Y-direction square pipes are fixedly connected between the two X-direction square pipes, each end of each X-direction square pipe is sleeved with one telescopic pipe, the back of each end of the X-direction square pipe is screwed with a first manual bolt, and the tail end of the first manual bolt abuts against the telescopic pipe; a hinge seat is installed on the back of each Y-direction square pipe, and the head of the large arm is located between the two Y-direction square pipes; the vacuum suction cup is installed on the head of the telescopic pipe exposed outside the X-direction square pipe. Through the telescopic arrangement of the suction cup frame, the occupied space of the suction cup frame can be reduced.

[0005] However, the above-mentioned patent still has the following problems: 1. The above-mentioned suction cup frame adopts a telescopic method, the range of reduction in the occupied space of the suction cup frame is limited, and it is difficult to effectively and directly solve the problem that the suction cup frame occupies a large space.

[0006] 2. The above-mentioned solution adopts a telescopic method for the suction cup frame, which has cumbersome steps and inconvenient operation in actual operation, especially it is difficult to efficiently adjust the suction cup frame on the construction site, affecting the work efficiency.

[0007] 3. The above-mentioned suction cup frame adopts a telescopic method, but due to the influence of processing accuracy and assembly errors, gaps are prone to appear between the telescopic pipe fittings, so when adsorbing ceramic tiles, especially heavy single-piece large-area ceramic rock slabs, the problem of loosening and shaking is prone to occur, which affects the stability of adsorbing the ceramic tiles. Utility Model Content

[0008] To overcome the shortcomings of existing technologies, this invention addresses the technical problem of folding the suction cup frame by incorporating a reversible main beam. This allows the main beam to be folded and rotated when navigating narrow spaces such as door frames or elevators, or when loading and transporting the tile-laying device. This reduces the space occupied by the suction cup frame, ensuring the tile-laying device's passability. The elimination of repeated disassembly of the suction cup frame improves operational convenience. Furthermore, the extension at the end of the main beam ensures a more secure connection between the main beam and the beam base when unfolded, reducing loosening issues. The extension of the main beam, fastened to the beam base, shares the stress on the rotating shaft, further enhancing the overall structural strength of the unfolded suction cup frame. The first locking head and locking slot allow the spring force to securely engage the first locking head in the first locking slot when the main beam is unfolded, locking the unfolded position. The second locking head and locking slot allow for locking the folded state of the main beam. With a simple and stable structure and low failure rate, it is suitable for long-term use in complex scenarios. The handle allows operators to pull the locking slider to disengage either the first or second locking head from the first or second locking port, thus unlocking the device. Both the unfolded and folded states require pulling the handle for unlocking, making operation convenient and logically clear. This facilitates quick operation on-site, improving work efficiency. The locking holes and safety bolts ensure that when the main beam is unfolded, the threaded connection between the locking holes and the safety bolts locks the main beam to the beam base, completely eliminating the gap between them. This prevents the suction cup holder from loosening and wobbling when adhering to tiles, improving the stability of tile adhesion. Furthermore, when the main beam is folded, the safety bolt inserted into the hole provides additional security, preventing the suction cup holder from disengaging during transport due to bumps, further enhancing safety.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a folding and avoidance structure for a suction cup frame of a tile laying device, comprising a beam base, with rotating shafts passing through both ends of the beam base, and main beams respectively hinged to the two rotating shafts. Multiple support beams are evenly spaced on both sides of each main beam, and a suction cup assembly is provided at the end of each support beam. Each main beam can rotate 90° around the rotating shaft to be in an unfolded and folded state respectively. A locking component is provided between the beam base and the two main beams, and a connector for connecting a tile laying auxiliary device is provided at the center of the connector.

[0010] Furthermore, the locking component includes locking sliders, two of which are symmetrically arranged and slidably connected to both ends of the beam seat. The locking sliders can lock the unfolded and folded states respectively. A slide rod seat is fixedly connected to the beam seat at the corresponding position of each locking slider. A slide rod is fixedly connected to one end of each locking slider near the slide rod seat. The end of the slide rod is slidably connected to the corresponding slide rod seat. A spring is provided between each locking slider and the corresponding slide rod seat, surrounding the outside of the slide rod.

[0011] Furthermore, each main beam has an extension at one end near the connector, the extension being able to be fastened to the outside of the beam seat, the end of the main beam extension having a first locking opening, the surface of the locking slider having a first groove at the corresponding position at the end of the main beam extension, the locking slider having a first locking head at the corresponding position of the first groove being slidably connected to the first groove, the first locking head being able to engage and fix with the first locking opening.

[0012] Furthermore, end caps are fixedly connected to both ends of the beam seat, and each locking slider is provided with a second locking head passing through the end cap at the corresponding position of the end cap. A second locking hole corresponding to the second locking head is opened on the main beam. When the main beam is in a folded state, the second locking head can be engaged and passed through the corresponding second locking hole.

[0013] Furthermore, a second groove is provided on the side of the beam seat away from the first groove along the sliding direction of the locking slider. A handle is slidably connected in the second groove, and the end of the handle passes through the second groove and is threadedly connected to the locking slider.

[0014] Furthermore, the beam seat and the surface of the main beam are provided with locking holes, the end of the second locking head is provided with a through insertion hole, a second fastener is fixedly connected to the main beam, the end of the second fastener is connected with a limit rope, the end of the limit rope away from the second fastener is fixedly connected to a first fastener, a safety bolt is sleeved inside the first fastener, the safety bolt can be threaded into the locking hole to lock in the unfolded state, and the safety bolt can be inserted into the insertion hole to lock in the folded state.

[0015] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: (1) By setting a flip-foldable main beam, when it is necessary to pass through narrow spaces, such as door frames, elevators, etc., or when it is necessary to load and transport, the main beam can be flipped and folded to greatly reduce the space occupied by the suction cup frame, ensure the passability of the tile laying device, and improve the ease of operation without having to repeatedly disassemble the suction cup frame.

[0016] (2) At the same time, by setting an extension at the end of the main beam, the connection between the main beam and the beam seat is more secure when the beam is unfolded, reducing the loosening problem between the beam seat and the main beam. The extension of the main beam is fastened on the beam seat to share the stress on the rotating shaft, thereby improving the overall structural strength of the suction cup frame after unfolding.

[0017] (3) By setting a first locking head and a first locking port, the first locking head can be stably locked in the first locking port by the elastic thrust of the spring when the main beam is unfolded, thus locking the unfolded position of the main beam. By setting a second locking head and a second locking port, the folded state of the main beam can be locked. The locking structure is stable and easy to operate, making it suitable for long-term use in complex scenarios.

[0018] (4) By setting a handle, the operator can pull the locking slider to slide, so that the first locking head is disengaged from the first locking port or the second locking head is disengaged from the second locking port, thereby completing the unlocking action. The unlocking action for both the unfolded and folded states is to pull the handle. The operation is convenient and the logic is clear, which makes it easy for the operator to operate quickly on the construction site and improve work efficiency.

[0019] (5) By setting locking holes and safety bolts, when the main beam is in the unfolded state, the main beam and the beam seat are locked by the threaded connection of the locking holes and safety bolts, completely eliminating the gap between the beam seat and the main beam, thereby avoiding the problem of loosening and shaking when the suction cup frame adsorbs the tiles, and improving the stability of the tile adsorption. At the same time, when the main beam is in the folded state, the setting of the safety bolts inserted into the insertion holes provides additional insurance for the locked state, avoiding the problem of the suction cup frame being released from the locked state due to bumps during loading and transportation, thereby further improving safety.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figure 1-8 As shown, a folding and avoidance structure for a suction cup holder of a tile laying device includes a beam base 10. A connector 14 for connecting the tile laying device is provided at the center of the beam base 10. A rotating shaft 15 is respectively passed through both ends of the beam base 10. A main beam 11 is hinged on the two rotating shafts 15. The main beam 11 can rotate 90° around the rotating shaft 15 to be in an unfolded and folded state respectively. An extension is provided at one end of each main beam 11 near the connector 14. The extension can be fastened to the outside of the beam base 10.

[0031] By setting a foldable main beam 11, when it is necessary to pass through narrow spaces such as door frames and elevators, or when it is necessary to load and transport the equipment, the main beam 11 can be flipped and folded to reduce the space occupied by the suction cup frame, ensuring the passability of the tile laying device. The ease of operation is improved by eliminating the need to repeatedly disassemble the suction cup frame.

[0032] Meanwhile, by providing an extension at the end of the main beam 11, the connection between the main beam 11 and the beam seat 10 is made more secure when the beam is unfolded, reducing the loosening problem between the beam seat 10 and the main beam 11. The extension of the main beam 11 is fastened to the beam seat 10 to share the stress on the rotating shaft 15, thereby improving the overall structural strength of the suction cup frame after unfolding.

[0033] like Figure 1-8As shown, each main beam 11 has a first locking opening 26 on its extension. A first groove 25 is provided on the beam seat 10 at the corresponding position of each first locking opening 26. A first locking head 16 is provided on each locking slider 19 at the corresponding position of the first groove 25 and is slidably connected to the first groove 25. Each first locking head 16 can engage with the corresponding first locking opening 26. The end of the first locking head 16 has an arc transition. A slide rod seat 23 is fixedly connected inside the beam seat 10 at the corresponding position of each locking slider 19. A slide rod 22 is fixedly connected to one end of the locking slider 19 near the slide rod seat 23. The slide rod 22 is slidably connected to the slide rod seat 23. A spring 24 is provided between each locking slider 19 and the corresponding slide rod seat 23 and surrounds the outside of the slide rod 22.

[0034] By setting the first locking head 16 and the first locking port 26, when the main beam 11 is unfolded, the elastic thrust of the spring 24 can be used to make the first locking head 16 stably locked in the first locking port 26, thereby locking the unfolded position of the main beam 11.

[0035] like Figure 1-8 As shown, end caps 20 are fixedly connected to both ends of the beam seat 10. Each locking slider 19 is provided with a second locking head 17 passing through the end cap 20 at the corresponding position of the end cap 20. A second locking port 27 corresponding to the second locking head 17 is opened on the main beam 11. A second slide groove 33 is opened on the side of the beam seat 10 away from the first slide groove 25 along the sliding direction of the locking slider 19. A handle 21 is slidably connected in the second slide groove 33. The end of the handle 21 passes through the second slide groove 33 and is threadedly connected to the locking slider 19.

[0036] By setting a second locking head 17 and a second locking port 27, when the main beam 11 is folded, the elastic thrust of the spring 24 can be used to make the second locking head 17 pass into the second locking port 27 to lock the folded state of the main beam 11. By setting a handle 21, the operator can pull the locking slider 19 to slide, so that the first locking head 16 disengages from the first locking port 26 or the second locking head 17 disengages from the second locking port 27, thereby completing the unlocking action. The unlocking action for both the unfolded and folded states is to pull the handle 21. The operation is convenient and the logic is clear, which makes it easy for operators to operate quickly on the construction site and improves work efficiency.

[0037] like Figure 1-8As shown, locking holes 32 are provided on the surfaces of the beam seat 10 and the main beam 11. A through insertion hole 18 is provided at the end of the second locking head 17. A second fastener 31 is fixedly connected to the main beam 11. A limit rope 30 is connected to the end of the second fastener 31. A first fastener 29 is fixedly connected to the end of the limit rope 30 away from the second fastener 31. A safety bolt 28 is sleeved inside the first fastener 29. The safety bolt 28 can be threadedly connected to the locking hole 32 when the main beam 11 is unfolded. The safety bolt 28 can be inserted into the insertion hole 18 when folded.

[0038] By setting the locking hole 32 and the safety bolt 28, when the main beam 11 is in the unfolded state, the locking hole 32 and the safety bolt 28 are used to lock the main beam 11 and the beam seat 10 together, completely eliminating the gap between the beam seat 10 and the main beam 11. This avoids the problem of loosening and shaking when the suction cup holder is adsorbing tiles, and improves the stability of tile adsorption. At the same time, when the main beam 11 is in the folded state, the setting of the safety bolt 28 through the insertion hole 18 provides additional security for the locked state, preventing the suction cup holder from falling out of the locked state due to bumps during loading and transportation, thereby further improving safety.

[0039] In this embodiment, initially, the suction cup holder is installed on the tile laying device through the connector 14, the main beam 11 is in the unfolded state, the first locking head 16 engages with the first locking port 26 to lock the unfolded state of the main beam 11, at this time the safety bolt 28 is threaded into the locking hole 32, and the beam seat 10 and the main beam 11 are tightly and firmly fixed. In this state, the operator can use the suction cup holder to pick up the tiles and use the tile laying device to carry out the tile laying work.

[0040] When the suction cup frame needs to pass through narrow spaces such as door frames or elevators, or needs to be transported to the construction site by truck, the main beams 11 on both sides need to be folded inward to reduce the space occupied by the suction cup frame.

[0041] The operator first unscrews the safety bolt 28 out of the locking hole 32, and then pulls the handle 21. The locking slider 19 retracts accordingly, and the first locking head 16 disengages from the first locking port 26, no longer restricting the main beam 11. The operator manually folds the main beam 11 inward while releasing the handle 21. When the main beam 11 is folded to nearly 90°, the edge of the second locking port 27 abuts against the arc end of the second locking head 17. As the main beam 11 folds further, the edge of the second locking port 27 presses against the second locking head 17 and the locking slider 19, causing them to retract inward. When the main beam 11 is fully folded to 90°, the second locking head 17 and the second locking port 27 are in the same position. Under the elastic thrust of the spring 24, the second locking head 17 penetrates into the second locking port 27, locking the main beam 11 in its folded state.

[0042] After the end of the second locking head 17 passes through the second locking port 27, the operator can vertically insert the safety bolt 28 into the insertion hole 18 to further lock the main beam 11 in the folded state.

[0043] When the main beam 11 needs to be unfolded again, the operator pulls the safety bolt 28 out of the socket 18, pulls the handle 21 to retract the locking slider 19, and the second locking head 17 disengages from the second locking port 27 to release the lock. The operator folds the main beam 11 outward until the edge of the first locking port 26 abuts against the end of the arc of the first locking head 16. If the main beam 11 is folded further, the edge of the first locking port 26 slides and rubs against the end of the arc of the first locking head 16, and directly pushes the socket 18 and the locking slider 19 to slide and retract along the slide rod 22 until the main beam 11 is completely flattened. Then, under the elastic thrust of the spring 24, the locking slider 19 is reset, and the first locking head 16 engages and is fixed with the first locking port 26. Then, the operator screws the safety bolt 28 into the locking hole 32 to further lock the beam seat 10 and the main beam 11.
