Description

Technical Field

[0001] The utility model belongs to the field of manual tile cutting machines, and in particular relates to a connection structure between a bottom plate and an extended side beam of a manual tile cutting machine. Background Art

[0002] One side of the base plate of the manual tile cutter (referred to as the cutter) will be equipped with expansion equipment such as a ruler as needed. The expansion equipment is connected to the expansion side beam on one side of the base plate. The expansion side beam is perpendicular to the cutting direction of the cutter when in use, that is, perpendicular to the long direction of the base plate. When not in use, it can be rotated and folded to be close to the base plate and keep parallel to the base plate, thereby reducing the size of the cutter and making it easy to carry.

[0003] In the existing cutting machine, the extended side beam is connected to the bottom plate through fasteners such as butterfly screws, flat washers, and hexagonal nuts. Whether locking the extended side beam or loosening the extended side beam, the butterfly screw needs to be turned many times, and it requires a lot of force to twist, which makes the operation more cumbersome. A rotating fulcrum is also required between the extended side beam and the bottom plate. The rotating fulcrum is fixed to the bottom plate in the form of welding. Its accuracy and firmness are limited by the skill level of the welding workers. It is easy to reduce the qualified rate of the cutting machine due to insufficient accuracy and insufficient firmness. In addition, during long-term use, the rotating fulcrum is easily deformed and damaged by external force collision. Once damaged, the entire bottom plate needs to be replaced, resulting in high maintenance costs for the cutting machine.

[0004] In summary, the existing cutting machines have the defects of being complicated to operate, having a low pass rate and having a high maintenance cost. Utility Model Content

[0005] The purpose of the utility model is to provide a connection structure between the bottom plate and the extended side beam of a manual tile cutting machine. The utility model has the advantages of convenient operation, high qualified rate, low maintenance cost and convenient transportation.

[0006] The technical solution of the utility model: a connection structure between the bottom plate and the extended side beam of a manual tile cutting machine, comprising a bottom plate, an extended side beam is provided on one side of the bottom plate, the extended side beam is perpendicular to the bottom plate, one side of the inner end of the extended side beam is rotatably connected to the bottom plate, the inner end of the extended side beam extends to the other side to form a pressure plate, a knob is provided on one side of the pressure plate, the knob is used to press the pressure plate, a hanging buckle is provided on the extended side beam, and a hook hole matching the hanging buckle is provided on the bottom plate.

[0007] In the connection structure between the bottom plate and the extended side beam of the aforementioned manual tile cutting machine, a cover plate is provided at the inner end of the extended side beam, the cover plate is connected to the bottom plate through the side beam support plate, one side of the cover plate is rotatably connected to one side of the side beam support plate, and the other side of the cover plate extends beyond the extended side beam to form a pressure plate.

[0008] In the aforementioned connection structure between the bottom plate of the manual tile cutting machine and the extended side beam, the knob is rotatably connected to the side beam support plate.

[0009] In the aforementioned connection structure between the bottom plate of the manual tile cutting machine and the extended side beam, the knob comprises a rectangular pressure block, a torsion plate is provided on the outer side of the pressure block, a boss is provided on the inner side of the pressure block, a buckle is provided on the inner side of the boss, a recess is provided on the inner side of the side beam support plate, and a through hole connected to the recess is provided on the outer side of the side beam support plate so that the buckle can enter the recess.

[0010] In the aforementioned connection structure between the bottom plate and the extended side beam of the manual tile cutting machine, the bottom plate and the extended side beam are both made of sheet metal or aluminum profiles with thin-wall structures.

[0011] In the connection structure between the bottom plate and the extended side beam of the aforementioned manual tile cutting machine, the side beam support plate is fixed on the inner side of the bottom plate, one end of the side beam support plate extends outward, passes through the bottom plate and is rotatably connected to the extended side beam, and a first through hole passed by the side beam support plate and a second through hole passed by the knob are provided on the bottom plate.

[0012] In the aforementioned connection structure between the bottom plate and the extended side beam of the manual tile cutting machine, the side beam support plate is connected to the bottom plate with screws.

[0013] Compared with the prior art, the utility model improves the connection structure between the bottom plate and the extended side beam on the basis of the existing cutting machine. When the extended equipment needs to be installed, the extended side beam only needs to be rotated to be perpendicular to the bottom plate, and then the knob is rotated at a certain angle, such as 90°, so that the extended side beam can be locked on the bottom plate, so that the extended side beam and the bottom plate remain perpendicular. When the extended equipment does not need to be installed, the extended side beam can be unlocked by rotating the knob, and the extended side beam can be rotated and kept parallel to the bottom plate. Since the number of turns of the knob when locking or unlocking the extended side beam is small, less than one turn, and the resistance during twisting is relatively small, the operation of the cutting machine is relatively convenient. In the utility model, the rotation fulcrum between the extended side beam and the bottom plate is located on the side beam bracket plate, and the side beam bracket plate is connected to the bottom plate with screws. The installation accuracy and firmness of the side beam bracket plate are easy to ensure, which improves the qualified rate of the cutting machine. Moreover, after the side beam bracket plate is damaged under the action of external force, it only needs to be replaced separately, and the bottom plate does not need to be replaced, which reduces the maintenance cost of the cutting machine. By arranging hooks on the extended side beams, when the extended side beams are folded to be parallel to the bottom plate, the extended side beams are fixed by the hooks to prevent the extended side beams from unfolding during transportation, thereby facilitating transportation of the cutting machine.

[0014] In summary, the utility model has the advantages of convenient operation, high pass rate, low maintenance cost and convenient transportation. BRIEF DESCRIPTION OF THE DRAWINGS

The extended side beam 2 is perpendicular to the bottom plate 1, and has the following characteristics:

[0025] The base plate 1 and the extended side beam 2 are made of sheet metal or aluminum profiles with thin-walled structures. The inner end of the extended side beam 2 is provided with a cover plate 7, which is fixed to the extended side beam 2. The cover plate 7 is connected to the base plate 1 through a side beam support plate 8. The side beam support plate 8 is located on the inner side of the base plate 1. The side beam support plate 8 is screwed to the base plate 1. One end of the side beam support plate 8 extends outward, passes through the base plate 1, and is rotatably connected to one side of the cover plate 7. The other side of the cover plate 7 extends beyond the extended side beam 2 to form a pressure plate 3. A knob 4 connected to the side beam support plate 8 is provided on one side of the pressure plate 3. The knob 4 is used to press the pressure plate 3, and light compression is sufficient. The base plate 1 is provided with a first through hole 16 passed by one end of the side beam support plate 8 and a second through hole 17 passed by the knob 4.

[0026] The knob 4 includes a rectangular pressing block 10, a torsion plate 11 is provided on the outside of the pressing block 10, a boss 12 is provided on the inside of the pressing block 10, the boss 12 is used to form a gap between the pressing block 10 and the side beam support plate 8 into which the pressing plate 3 can enter, and a buckle 13 is provided on the inside of the boss 12. A recessed portion 14 is provided on the inside of the side beam support plate 8, and the recessed portion 14 leaves sufficient space for the installation of the buckle 13.
