DETAILED DESCRIPTION
[0026] The utility model will be further described in connection with the drawings and examples:
[0027] Example one: refer to Figures 1 to 3 As shown in the drawing, an adjustable abutment includes abutment 1 and baffle 2, the baffle 2 is arranged at the rear side of the abutment 1, one side of the abutment 1 is rotatably connected with a fulcrum bolt 3, the top of the other side of the abutment 1 is provided with upwardly extending position plate 4, the position plate 4 is provided with adjusting screw hole 5, and the abutment 1 has longitudinal spacing between the rear end face and the baffle 2.
[0028] Further provided is adjusting bolt 6, the front end of the adjusting bolt 6 is connected with the adjusting screw hole 5 by screwing, and the rear end of the adjusting bolt 6 is arranged opposite the baffle 2.
[0029] In the embodiment, the backstop is arranged at the tile placing position, and the stopper is fixedly arranged. When the tile needs to be cut, the tile is placed at the tile placing position, and the end of the tile is abutted against the front end surface of the backstop, and then the tile is cut by the cutting component above the tile. The cutting component can be a manual cutting component or an electric cutting component. Since the moving track of the cutting component is basically fixed, for the flawless tile, that is, the two adjacent edges of the tile are perpendicular to each other. If the front side surface of the backstop is slightly worn, so that the front end surface of the backstop is not perpendicular to the moving track of the cutting component, or the guide rail for guiding the movement of the cutting component is deformed or has other problems, so that the moving track of the cutting component is not perpendicular to the front end surface of the backstop, the backstop is adjusted, so that the front end surface of the backstop is perpendicular to the moving track of the cutting component, so as to ensure the cutting precision and quality of the subsequent tile. When the backstop needs to be adjusted, the adjusting bolt is rotated, and the distance between the rear end of the adjusting bolt and the rear end surface of the positioning plate is adjusted, so that the angle of the backstop is adjusted. In the embodiment, the left rear side of the backstop is rotatably connected with the fulcrum bolt. In the initial state, the distance between the rear end surface of the adjusting bolt and the rear end surface of the positioning plate is d, and the front end surface of the backstop is flush with the reference line when the adjusting bolt is in contact with the stopper. When the backstop is adjusted, the rear end surface of the adjusting bolt is away from the positioning plate, so that the distance between the rear end surface of the adjusting bolt and the rear end surface of the positioning plate is d1, and d1>d. When the tile is abutted against the front end surface of the backstop and the right end of the backstop is counterclockwise rotated around the fulcrum bolt, the rear end surface of the adjusting bolt is abutted against the stopper, and at this time, the front end surface of the backstop is inclined to the right relative to the reference line. If the distance between the rear end surface of the adjusting bolt and the rear end surface of the positioning plate is d2, d2<d, and the rear end of the adjusting bolt is abutted against the stopper, the front end surface of the backstop is inclined to the left relative to the reference line. In this adjustment mode, only the adjusting bolt needs to be rotated, so that the inclination angle of the front end surface of the backstop can be adjusted until the front end surface of the backstop is perpendicular to the moving track of the cutting component, or the included angle between the front end surface of the backstop and the moving track of the cutting component reaches a preset value.
[0030] Referring to Figure 3 The utility model also provides a tile cutting machine, including support seat 7, setting in support seat 7 directly above the slide rod 8 and the cutting component 9 of sliding setting on slide rod 8, two ends of slide rod 8 are connected with the top two ends of support seat 7 respectively through a connecting piece 10, still be equipped with above adjustable backstop, backstop 1 and stopper 2 set up between two side connecting piece 10, and backstop 1 and stopper 2 are close to one side connecting piece 10 setting, stopper 2 is connected with one side connecting piece 10, the bottom of backstop 1 is abutted on the top surface of support seat 7, and the bottom of fulcrum bolt 3 is connected with support seat 7.
[0031] In the embodiment, the support seat is used for placing the ceramic tile, when the ceramic tile is cut, the ceramic tile is placed on the support seat, the end surface of the ceramic tile opposite to the abutment is abutted on the abutment, and the right end of the abutment is pushed to rotate around the fulcrum bolt, so that the rear end of the adjusting bolt is abutted on the retaining edge, at this time, the abutment is at a preset angle, and when the cutting component moves along the slide rail, the ceramic tile can be stably cut. The cutting component can be a manual cutting component or an electric cutting component, and in the utility model drawings, the cutting component is an electric cutting component.
[0032] Referring to Figure 2 As shown in the figure, the retaining edge 2 is provided with a strip-shaped hole 11 opposite to the adjusting screw hole, the rear end of the adjusting bolt 6 penetrates through the strip-shaped hole 11 and is arranged at the rear side of the retaining edge 2, and a limiting nut 12 is further screwed on the adjusting bolt 6 and arranged between the retaining edge 2 and the positioning plate 4. Preferably, the limiting nut is a self-locking nut, so that after the position of the limiting nut is adjusted, the limiting nut cannot rotate relative to the adjusting bolt.
[0033] The width of the strip-shaped hole 11 matches the diameter of the adjusting bolt 6, and the length of the strip-shaped hole 11 is greater than the diameter of the adjusting bolt 6.
[0034] The rear end of the adjusting bolt 6 is provided with a screw head 13 arranged at the rear side of the retaining edge 2.
[0035] In the embodiment, in order to limit the rotation angle of the abutment and prevent the abutment from rotating too much and separating from the support seat, the strip-shaped hole, the screw head and the limiting nut are arranged, the front end of the adjusting bolt penetrates through the strip-shaped hole and is screwed with the adjusting screw hole, since the screw head is arranged at the rear side of the retaining edge, when the right end of the abutment rotates forward, the abutment is limited by the screw head and the retaining edge, and the rotation angle of the abutment is limited. When the right end of the abutment rotates backward, the abutment is limited by the limiting nut. When the angle of the abutment needs to be adjusted, only the limiting nut can be rotated, so that when the right end of the abutment rotates backward, the limiting nut is abutted on the retaining edge. If the distance between the positioning plate and the screw head is too large, at this time, the abutment can rotate a large angle, therefore, the adjusting bolt is further rotated, the distance between the screw head and the positioning plate is shortened, under the condition that the positions of the positioning plate and the retaining edge are not changed, the distance between the limiting nut and the screw head is shortened, so that the rotation angle of the abutment is reduced (under normal circumstances, the abutment can rotate around the fulcrum bolt, and is not completely fixed).
[0036] Meanwhile, the strip-shaped hole can ensure the normal screwing of the adjusting bolt and the adjusting screw hole, and further, since the abutment can rotate with the fulcrum bolt, at this time, a small vertical deviation can occur between the abutment and the fulcrum bolt, therefore, the strip-shaped hole and the adjusting bolt can also limit the upward movement of the abutment relative to the support seat (the downward movement of the abutment can be limited by the support seat itself).
[0037] The backrest is rotatably connected with the fulcrum bolt through the positioning hole.
[0038] Referring to Figure 1 The backrest 1 is provided with a rear extending fulcrum 14 on the rear side, which is arranged on the rear side of the fulcrum bolt 3, and the rear end of the fulcrum 14 abuts against the front side of the retaining edge 2.
[0039] The fulcrum is a triangular structure, and the rear end of the fulcrum is an arc surface abutting against the front side of the retaining edge.
[0040] In the embodiment, in order to prevent the positioning hole and the fulcrum bolt from contacting each other when the backrest rotates relative to the fulcrum bolt, and to prevent insufficient rotation adjustment accuracy of the backrest due to relative wear, the fulcrum is arranged to abut against the retaining edge during rotation of the backrest, thereby preventing wear between the fulcrum bolt and the backrest and ensuring the rotation adjustment accuracy. Meanwhile, the arc surface is arranged to ensure stability and smoothness during rotation of the backrest and prevent the occurrence of jamming.
[0041] The top of the supporting base is provided with a mounting screw hole, the bottom of the fulcrum bolt is screwed with the mounting screw hole, the top of the fulcrum bolt is provided with a top screw head, and the distance between the top screw head and the supporting base is greater than the thickness of the backrest.
[0042] The mounting screw hole is used for connecting the fulcrum bolt, and the top screw head is used for limiting the backrest to prevent the backrest from moving upward and being separated. Further, the fulcrum bolt does not completely lock the backrest on the supporting base, so that the backrest can normally rotate around the fulcrum bolt.
[0043] Meanwhile, in order to facilitate the rotation of the adjusting bolt and prevent the connecting piece from affecting the rotation of the adjusting bolt, the retaining edge at the rear end of the adjusting bolt is arranged on the side of the connecting piece.
