[0002] A cutting machine is a commonly used tool for cutting tiles and other boards. The cutting machine consists of a base, a crossbeam, and a cutting mechanism. To facilitate the support of the board, a strip-shaped support plate is usually installed on the side wall of the base. The support plate and the base form a support mechanism.

[0003] The existing support plate is directly fixed to the base through a fixing structure. When the cutting machine is folded up, the support plate needs to be removed in order to reduce the volume, which is very inconvenient. Summary of the Invention

[0004] In view of the above problems, the present invention proposes a support mechanism for a cutting machine and a cutting machine.

[0007] When the support plate is connected to the base through the limiting structure, the support plate is in a working state, and the support plate and the base are used to support the plate; when the second side of the mounting end is no longer connected to the base, the support plate can be rotated back and forth relative to the base to be folded, and because the first side of the mounting end is rotated in conjunction with the limiting frame, the limiting frame can be flipped up and down relative to the base, and the support plate can also be flipped up or down, so that the support plate can be folded up and down conveniently and quickly without the need to remove the entire support plate from the base.

[0008] In one embodiment of the present invention, the support plate has an expanded working position, a first folded working position and a second folded working position. When in the expanded working position, the second side of the mounting end is connected to the base through a limiting structure, and the support plate is perpendicular to the base; when in the first folded working position, the second side of the mounting end is separated from the base, and the support plate is parallel to the base after rotation; when in the second folded working position, the support plate is folded upward through the limiting frame on the basis of the first folded working position.

[0009] In one embodiment of the present invention, the base has a limiting mechanism. When the support plate is located in the second folded working position, the end of the support plate away from the limiting frame is fixed in cooperation with the limiting mechanism. The support plate and the limiting mechanism are snap-fitted, magnetically attracted, or fastened.

[0010] In one embodiment of the present invention, the limiting mechanism is a vertical plate arranged at the end of the base, the vertical plate has a supporting step or the vertical plate and the base form a supporting step, and the supporting plate cooperates with the supporting step; the vertical plate has a first magnetic part, and the supporting plate has a second magnetic part, and the first magnetic part and the second magnetic part are magnetically attracted and cooperated.

Specifically, the head of the first support plate near the riser (the end that cooperates with the limit frame) has a first magnetic portion.

[0014] In one embodiment of the present invention, a second support plate is further included, which is installed on the side of the base. The first support plate and the second support plate are respectively located on the left and right sides of the base. Support rollers are installed on the second support plate, and the support rollers are used to roll with the lower end surface of the plate to be cut.

[0015] The design of the supporting rollers allows the plate to have rolling friction when moving, which can effectively reduce resistance, facilitate the movement of the plate, and provide a good user experience.

[0016] In one embodiment of the present invention, a first elastic element is installed on one end of the first support plate and the second support plate away from the base, and the first elastic element is used to cooperate with the support surface. The first elastic element includes:

[0019] The return spring is arranged in the housing, and its end portion cooperates with the movable column to make the movable column have a movement tendency to move outward.

[0020] By arranging the first elastic element at the end of the support plate, the support plate is in elastic contact with the ground, which can better maintain balance.

[0021] In one embodiment of the present invention, the base has a horizontally arranged rotating hole, the limit frame has a rotating shaft extending into the rotating hole, the limit frame also has a first limit hole, and the first side of the mounting end has a second limit hole coaxially arranged with the first limit hole. The support plate and the limit frame are rotated together by a first pin shaft passing through the first limit hole and the second limit hole.

[0022] In one embodiment of the present invention, the limiting structure includes a third limiting hole provided on the base, and a fourth limiting hole is provided on the second side of the mounting end, wherein the fourth limiting hole is used to cooperate with the third limiting hole. When the working position is expanded, the support plate and the limiting frame are limited by a second pin shaft passing through the third limiting hole and the fourth limiting hole.

[0023] Alternatively, the limiting structure includes a limiting bolt, and when the working position is expanded, the second side is fixed to the base through the limiting bolt.

[0024] The present application also discloses a cutting machine, comprising the support mechanism described above, wherein the base has vertical plates on both sides, and the crossbeam is fixed to the upper part of the vertical plates;

[0025] A cutting ruler is also mounted on the base, comprising a mounting base and two symmetrically arranged adjustment assemblies, wherein the crossbeam is located in the middle of the two adjustment assemblies, and the adjustment assembly comprises a strip rod and a first locking member, one end of the strip rod being rotatably mounted on the mounting base, and the end of the strip rod that cooperates with the mounting base further comprising an adjustment portion extending outward, the adjustment portion being provided with an arcuate groove, and one end of the first locking member being passed through the arcuate groove and connected to the mounting base to lock or unlock the adjustment portion;

[0048] The present invention will be described in detail below with reference to the accompanying drawings.

[0049] Example 1

[0050] like Figure 1 As shown, this embodiment discloses a cutting machine, which includes a base 1 , a beam 2 located above the base 1 , and a cutting mechanism 3 movably arranged on the beam 2 .

[0051] like Figure 1 、 2As shown in Figure 3, a cutting ruler 4 is mounted on the base 1. The cutting ruler 4 includes a mounting base 5 and at least one set of adjustment components 6 provided on the mounting base 5. The adjustment component 6 includes a strip rod 7 and a first locking member 8. One end of the strip rod 7 is rotatably mounted on the mounting base 5. The end of the strip rod 7 that cooperates with the mounting base 5 also has an adjustment portion 9 extending outward. The adjustment portion 9 is provided with an arcuate groove 10. One end of the first locking member 8 passes through the arcuate groove 10 and is used to connect with the mounting base 5 to lock or unlock the adjustment portion 9.

[0052] The adjusting portion 9 or the bar 7 has an indicator portion 11, and the mounting seat 5 has an angle mark 12, or the mounting seat 5 has an indicator portion 11 and the adjusting portion 9 has an angle mark 12;

[0053] The indicator 11 is aligned with the angle marking 12 for easy reading of angle data.

[0054] The strip rod 7 of the cutting ruler 4 of the present application can be rotated relative to the mounting base 5. The first locking member 8 can lock the strip rod 7 after the strip rod 7 is rotated into place. The rotation angle of the strip rod 7 can be determined by the cooperation of the arc groove 10, the angle marking line 12 and the indicating part 11. The cutting ruler 4 can assist the cutting machine in cutting a variety of angles and has strong applicability.

[0055] The indicating portion 11 of the present application may be in the shape of a convex portion, a pointed portion, etc., and may also be provided on a corresponding component by pasting, engraving, or printing.

[0056] The angle marking line 12 of the present application can be set on the corresponding component by sticking, engraving or printing, or can be formed by fixing an angle ruler on the corresponding component.

[0057] The strip rod 7 of the present application can be rotatably mounted on the mounting seat 5 via a rotating shaft.

[0058] like Figure 2 and 3 As shown, in this embodiment, the arcuate groove 10 is arranged around the rotation axis 49 of the strip rod 7; the strip rod 7 has a length mark 13; a movable ruler 14 is slidably mounted on at least one strip rod 7, and a second locking member 15 is mounted on the movable ruler 14. The second locking member 15 is used to fix the movable ruler 14 to the strip rod 7 after the movable ruler 14 is adjusted into place. The movable ruler 14 has an L-shaped structure and includes a first portion 16 parallel to the length direction of the strip rod 7 and a second portion 17 perpendicular to the first portion 16.

[0059] The movable ruler 14 can cooperate with the strip rod 7 to limit the piece to be cut, wherein the first part 16 can assist the length mark 13 to facilitate data reading, and the second part 17 can realize the positioning function and reliably limit the piece to be cut.

[0060] In actual use, the second locking member 15 can be screwed onto the movable ruler 14 , and by tightening the second locking member 15 , the end of the second locking member 15 is pressed against the strip ruler, thereby fixing the movable ruler 14 and the strip rod 7 .

[0061] The length marking line 13 of the present application can be set on the strip rod 7 by sticking, engraving or printing, or can be formed by fixing a ruler on the strip rod 7.

[0062] In actual use, at least one of the first portion 16 and the second portion 17 of the movable ruler 14 has a marking line 18, which can be used to measure distance and further facilitate the cutting operation. Preferably, both the first portion 16 and the second portion 17 of the movable ruler 14 have a marking line 18.

[0063] In this embodiment, the mounting base 5 has a threaded hole, and the first locking member 8 is threadedly engaged with the threaded hole. This fixing method is simple and convenient.

[0064] In this embodiment, an adjustable stopper 19 is threaded onto the mounting base 5. The end of the adjustable stopper 19 is used to abut against the strip rod 7 to limit the rotation angle of the strip rod 7. In actual use, the two adjustable stoppers 19 can ensure that the two strip rods 7 are extended to form a 180° angle. When the cutting angle is not required, it can be used as a standard ruler.

[0065] In other embodiments, at least one of the strip rods 7 is equipped with an infrared emitting device, which is used to emit light along the length direction of the strip rod 7. The rotation position of the strip rod 7 can be easily adjusted and checked by the infrared emitting device.

[0066] In this embodiment, the cross section of the strip rod 7 is a U-shaped structure. The U-shaped structure can ensure the structural strength of the strip rod 7 and is also easy to process.

[0067] In this embodiment, there are two sets of adjustment components 6, which are respectively arranged on both sides of the mounting base 5, and the crossbeam 2 is located in the middle of the two sets of adjustment components 6; the end of the strip rod 7 away from the mounting base 5 has a support column 24. The support column 24 is used to cooperate with the support surface.

[0068] like Figure 1 As shown, in this embodiment, the cutting mechanism 3 includes a movable seat 20 that cooperates with the beam 2 and an operating handle 21 fixed to the movable seat 20. The operating handle 21 is a retractable operating handle 21. The operating handle 21 includes at least two tube bodies 22 that are socketed with each other, and also includes a locking structure 23 for fixing two adjacent tube bodies 22.

[0069] The retractable operating handle 21 is designed so that the operator can adjust the length of the operating handle 21 as needed, which provides a better user experience of the cutting machine.

[0070] One form of the locking structure 23 is: a locking bolt is screwed onto the outer tube body 22, and the locking bolt is tightened so that the bolt abuts against the inner tube body 22, thereby fixing the two adjacent tube bodies 22 relative to each other. When the locking bolt is loosened, the two adjacent tube bodies 22 can move relative to each other.

[0071] In other embodiments, the cutting ruler 4 can also be configured as follows: it includes a mounting base 5 and at least one set of adjustment components 6 disposed on the mounting base 5, the adjustment component 6 including a bar 7 and a first locking member 8, one end of the bar 7 being rotatably mounted on the mounting base 5, the mounting base 5 having an arcuate groove, one end of the first locking member 8 passing through the bar 7 and located within the arcuate groove, for locking the bar 7 and the mounting base 5 after the bar 7 is adjusted into place; the mounting base 5 has angle markings at positions corresponding to the arcuate groove, the bar 7 having an indicator portion 11 that matches the angle markings, the indicator portion 11 being used to align with the angle markings 12 to facilitate reading of angle data. The arcuate groove is disposed around the rotation axis 49 of the bar 7; the bar 7 has a length marking 13; the arcuate groove is an anti-slip groove, a slider is slidably disposed within the arcuate groove, the slider has a threaded hole, and the first locking member 8 is threadedly engaged with the slider.

[0072] like Figure 1 and 4 As shown, the cutting machine of this embodiment also includes a supporting mechanism, which includes a base 1. A first supporting plate 25 is installed on one side of the base 1. A first elastic element 26 is installed on the end of the first supporting plate 25 away from the base 1. The first elastic element 26 is used to cooperate with the supporting surface.

[0073] By disposing a first elastic element 26 at the end of the first support plate 25, the first support plate 25 is in elastic contact with the ground, which can better maintain balance. In actual use, the first elastic element 26 can be a spring or a spring.

[0074] The support surface mentioned in this application refers to the ground or work surface that supports the cutting machine.

[0075] like Figure 7 、 8 As shown in FIG9 , in this embodiment, the first elastic element 26 includes:

[0076] a hollow housing 27;

[0077] A movable column 28 is movably mounted in the housing 27 , with one end of the movable column 28 extending out of the housing 27 . The portion of the movable column 28 located in the housing 27 has an anti-slip portion 29 .

[0078] The return spring 30 is disposed in the housing 27 , and its end portion cooperates with the movable post 28 to enable the movable post 28 to have a movement tendency to move outward.

[0079] The first elastic element 26 is arranged in this way for easy installation, and can provide elastic support through the cooperation of the return spring 30 and the movable column 28.

[0080] In actual use, the housing 27 of the first elastic element 26 is fixed to the corresponding support plate by clamping, welding or fasteners.

[0081] like Figure 4 As shown, in this embodiment, a first elastic element 26 is also installed on the end of the first support plate 25 close to the base 1. With this arrangement, when the cutting machine is installed with a plate to be cut, the extension portion 44 can abut against the upper surface of the base 1 under the action of the plate's gravity, thereby improving the stability of the entire support structure.

[0082] like Figure 1 As shown, the first support plate 25 further has an extension portion 44 extending to the upper surface of the base 1 .

[0083] like Figure 8 and 9 As shown, in this embodiment, there are two movable columns 28 and two return springs 30 in the housing 27. The movable columns 28 and the return springs 30 are matched one by one. The design of two movable columns 28 can provide better support and achieve better balance effect.

[0084] like Figure 8 and 9 As shown, in this embodiment, the housing 27 includes a main body 31 with an open end and a cover 32 for covering the open end of the main body 31. The main body 31 has a partition 33, and the two movable columns 28 are respectively located on either side of the partition 33. This configuration of the housing 27 facilitates the installation and maintenance of the first elastic element 26.

[0085] In this embodiment, the cover 32 is fixed to the body 31 by fasteners connected to the partition 33. The outer wall of the body 31 has a threaded hole that extends to the partition 33. This arrangement makes the partition 33 a fixed carrier, and the entire structure is strong and compact.

[0086] like Figure 1 and 4 As shown, in this embodiment, a second support plate 47 is mounted on the other side of the base plate. Support rollers 35 are mounted on the second support plate 47. Support rollers 35 are configured to roll with the lower end surface of the plate to be cut. The design of support rollers 35 ensures rolling friction when the plate is moved, effectively reducing resistance, facilitating plate movement, and providing a good user experience.

[0087] like Figure 1 and 4As shown, in this embodiment, a second elastic element 34 is installed on the side wall of the base 1. The structure of the second elastic element 34 is the same as that of the first elastic element 26. The movable column 28 of the first elastic element 26 extends downward, and the movable column 28 of the second elastic element 34 extends upward. The second support plate 47 is fixed to the movable column 28 of the second elastic element 34 at one end close to the bottom plate. The second support plate 47 also has an extension portion 44 extending to the upper surface of the base 1.

[0088] In actual use, the base 1 is provided with a slag discharge hole. By providing the slag discharge hole, it is convenient to clean up the waste slag.

[0089] like Figure 4 As shown, in this embodiment, a movable roller 59 is installed at one end of the base 1, and a handle 60 is installed at the other end. By providing the movable roller 59 and the handle 60, the cutting machine can be easily moved.

[0090] like Figure 1 As shown, in this embodiment, the first support plate 25 has a scale and a slide groove 62, and a backrest 36 is installed on the first support plate 25. The backrest 36 has a strip hole 37 and is fixed to the slide groove 62 by a fixing member 38 passing through the strip hole 37. The backrest 36 has an upwardly bent abutment 39. The abutment 39 is used to cooperate with the plate. The backrest 36 can rotate and slide on the slide groove 62, and the backrest 36 can provide more diverse cutting functions.

[0091] like Figure 1 、 4 , 5, 6, 10 and 11, the first support plate 25 of the support mechanism of the cutting machine can be rotated and folded, specifically: the end of the first support plate 25 close to the base 1 is the mounting end 40, and the side of the base 1 is rotatably mounted with a limiting frame 41, and the limiting frame 41 can be flipped up and down relative to the base 1, and the mounting end 40 of the first support plate 25 has a first side 42 and a second side 43, and the first side 42 of the mounting end 40 is rotatably matched with the limiting frame 41, and the first support plate 25 can be rotated forward and backward relative to the base 1, and the second side 43 of the mounting end 40 is detachably connected to the base 1 through a limiting structure.

[0092] When the first support plate 25 is connected to the base 1 through the limiting structure, the first support plate 25 is in a working state, and the first support plate 25 and the base 1 are used to support the plate; when the second side 43 of the mounting end 40 is no longer connected to the base 1, the first support plate 25 can be rotated forward and backward relative to the base 1 to fold, and because the first side 42 of the mounting end 40 is rotated and matched with the limiting frame 41, the limiting frame 41 can be flipped up and down relative to the base 1, and the first support plate 25 can also be flipped up or down, so that the first support plate 25 can be quickly and conveniently folded without removing the entire first support plate 25 from the base 1.

[0093] like Figure 1 、 10 As shown in FIG11 , in this embodiment, the first support plate 25 has an extended working position, a first folded working position and a second folded working position.

[0094] In this embodiment, the base 1 has a limiting mechanism. When the first support plate 25 is in the second, retracted working position, the end of the first support plate 25 away from the limiting frame 41 is engaged and fixed with the limiting mechanism. In actual use, the first support plate 25 and the limiting mechanism are engaged by snapping, magnetic attraction, or fasteners.

[0095] like Figure 1 As shown, in this embodiment, the limiting mechanism is a vertical plate 45 provided at the end of the base 1. The vertical plate 45 has a support step 46 or the vertical plate 45 and the base 1 form a support step 46, and the first support plate 25 cooperates with the support step 46; the vertical plate 45 has a first magnetic portion 61, and the first support plate 25 has a second magnetic portion (not shown in the figure), and the first magnetic portion 61 and the second magnetic portion are magnetically engaged.
