Description

Technical Field

[0001] This utility model belongs to the field of manual tile cutting machines, and in particular relates to a manual tile cutting machine with an adjustable positioning size for an extended edge beam. Background Technology

[0002] The existing manual tile cutter (hereinafter referred to as the cutter) has the following structure: a base plate with a cutting assembly on it; the cutting assembly includes a guide rail located above the base plate, with both ends of the guide rail fixed to the base plate; a slider is mounted on the guide rail, and a handle is rotatably connected to the slider; a cutting wheel is located at the bottom of the handle. When a tile is placed on the base plate, the handle is pressed down, causing the cutting wheel to contact the tile; pushing the handle further causes the cutting wheel to cut the tile.

[0003] Typically, a sliding bar is installed on the wide side of the base plate of the cutting machine. An extension beam is rotatably connected to the sliding bar. A straightedge can be installed on the extension beam. A stainless steel ruler with graduations is installed on the top surface of the extension beam. When the extension beam is rotated to be perpendicular to the base plate, one side of the tile is against the straightedge. The width of the tile after cutting can be read from the graduations on the steel ruler.

[0004] In existing cutting machines, the steel ruler and the extension beam are connected by screws. When installing the steel ruler onto the extension beam, in order to make the tile cutting width accurate, it is necessary to fine-tune the position of the scale, that is, fine-tune the installation position of the steel ruler on the extension beam. The method is to first loosen the screws, then move the steel ruler until the steel ruler is in the correct position, and then tighten the screws.

[0005] The existing cutting machine has the following defects: First, the purchase cost of the steel ruler is high, which increases the overall cost of the cutting machine; Second, the main body of the extension beam is made of hollow aluminum profile, which is relatively soft. The length of the screw connection between the steel ruler and the extension beam is short, and the screw is prone to stripping, which makes it impossible to fix the steel ruler and results in a high failure rate; Third, when the screw is tightened, the steel ruler is prone to displacement again due to the rotational friction force of the screw, which requires readjustment. The adjustment process is time-consuming and labor-intensive. Utility Model Content

[0006] The purpose of this invention is to provide a manual tile cutter with an adjustable positioning dimension for the extended edge beam. This invention has the advantages of low overall cost, low failure rate, time-saving and labor-saving adjustment, and high adjustment accuracy.

[0007] The technical solution of this utility model is as follows: A manual tile cutter with adjustable positioning dimensions for an extended edge beam, comprising a base plate, a cutting assembly on the base plate, a slide bar on the wide side of the base plate, the slide bar being connected to an extended edge beam via an edge beam cover, one side of the edge beam cover being rotatably connected to the slide bar, an adjusting screw and a locking screw being provided between the edge beam cover and the extended edge beam, the adjusting screw being parallel to the extended edge beam, a scale being provided on the top surface of the extended edge beam, and the extended edge beam being inserted into the edge beam cover.

[0008] In the aforementioned manual tile cutter with adjustable positioning dimensions for the extended side beam, the side beam cover has a recess on its side wall facing away from the extended side beam. The adjusting screw passes through the recess and connects to the extended side beam, with the screw head located inside the recess.

[0009] In the aforementioned manual tile cutter with adjustable positioning dimensions for the extended side beam, the side beam cover is provided with an adapter plate that is inserted into the extended side beam. The extended side beam is provided with an elongated hole corresponding to the position of the adapter plate. The locking screw passes through the elongated hole and connects to the adapter plate.

[0010] In the aforementioned manual tile cutter with adjustable positioning dimensions for the extended side beam, the side beam cover is provided with two adapter plates, and the extended side beam has elongated holes on both sides in the width direction. There are two locking screws, which pass through the corresponding elongated holes and are connected to the corresponding adapter plates.

[0011] In the aforementioned manual tile cutter with adjustable positioning dimensions for the extended side beam, the bottom of the side beam cover is provided with a set screw for connecting the adjusting screw.

[0012] In the aforementioned manual tile cutter with adjustable positioning dimensions for the extended side beam, the base plate has a first groove on its wide side, and the slide bar is located within the first groove.

[0013] In the aforementioned manual tile cutter with adjustable positioning dimensions for the extended side beam, a locking fastener is provided between the other side of the side beam cover and the slide bar or base plate.

[0014] In the aforementioned manual tile cutter with adjustable positioning dimensions for the extended edge beam, a second groove is provided on the top surface of the extended edge beam.

[0015] Compared with the prior art, the present invention makes the following improvements based on the existing cutting machine:

[0016] 1) The steel ruler that was originally fixed on the extension beam has been eliminated, and the scale is directly made on the extension beam, saving the cost of the steel ruler and making the overall cost of the cutting machine lower.

[0017] 2) Since the scale is formed directly on the extended edge beam without the need for a steel ruler, the screw connection between the steel ruler and the extended edge beam is eliminated, reducing the failure rate.

[0018] 3) During the adjustment of the scale position, after the extended side beam is moved to the accurate position, it is still constrained by the side beam cover and the adjusting screw. The process of tightening the locking screw will prevent the extended side beam from moving, avoiding the process of readjustment, reducing the number of adjustments, and making the adjustment process time-saving and labor-saving.

[0019] 4) By adjusting the screw, the relative position between the extension beam and the beam cover can be changed. Turning the adjusting screw one turn will only move the extension beam a short distance, which can make the adjustment accuracy of the scale high.

[0020] In summary, this utility model has the advantages of low overall cost, low failure rate, time-saving and labor-saving adjustment, and high adjustment accuracy. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0027] Example. A manual tile cutter with an adjustable positioning dimension for an extended edge beam, such as... Figure 1 As shown, it includes a base plate 1, on which a cutting assembly 2 is mounted, with the following features:

[0028] The base plate 1 has first sliding grooves 12 on both sides in the width direction. Sliding strips 3 are installed within the first sliding grooves 12. The sliding strips 3 are connected to an extended side beam 5 via a side beam cover 4. The extended side beam 5 is perpendicular to the base plate 1. The side beam cover 4 fits against the side wall of the base plate 1. One side of the side beam cover 4 is rotatably connected to the sliding strip 3, and a locking fastener is provided between the other side of the side beam cover 4 and the sliding strip 3 or the base plate. The fastener can be a bolt, which passes through the other side of the side beam cover 4 and connects to the sliding strip 3, or a nut can be placed in the first sliding groove 12, with the bolt passing through the other side of the side beam cover 4 and connecting to the nut. Threaded holes can be provided on the sliding strip 3, with screws installed in the threaded holes to press against the bottom surface of the first sliding groove 12, thus fixing the position of the sliding strip 3.

[0029] An adjusting screw 6 and two locking screws 7 are provided between the side beam cover 4 and the extended side beam 5. The adjusting screw 6 is parallel to the extended side beam 5. The top surface of the extended side beam 5 is provided with a scale 8. The scale 8 can be formed on the extended side beam 5 by photolithography or laser marking technology. The extended side beam 5 is inserted into the side beam cover 4.

[0030] like Figure 2 As shown, the side beam cover 4 has a recess on its side wall facing away from the extended side beam 5. The adjusting screw 6 passes through the recess and connects to the extended side beam 5. The head of the adjusting screw 6 is located inside the recess 14.

[0031] The side beam cover 4 is provided with two adapter plates 9 that are inserted into the extended side beam 5. The extended side beam 5 has elongated holes 10 on both sides in the width direction that correspond to the positions of the adapter plates 9. The locking screw 7 passes through the elongated holes 10 and connects to the adapter plates 9.

[0032] The bottom of the side beam cover 4 is provided with a set screw 11 that connects to the adjusting screw 6, and the set screw 11 tightens the adjusting screw 6.

[0033] The top surface of the extended side beam 5 is provided with a second sliding groove 13.

[0034] Instructions for use: When the cutting machine is not in use, loosen the fasteners on one side of the side beam cover 4 to rotate the extended side beam 5 to be parallel to the base plate 1, reducing the size of the cutting machine and making it easier to store and transport.

[0035] like Figure 4 As shown, the straightedge 15 is installed on the extended side beam 5 and kept parallel to the base plate 1. The straightedge 15 and the extended side beam 5 are connected by bolts and nuts. That is, take a nut and place it in the second slide groove 13, and use a bolt to pass through the straightedge 15 to lock the nut.

[0036] When adjusting scale 8, loosen the fastener on one side of the side beam cover 4 so that the extended side beam 5 can rotate to expose the adjusting screw 6. Loosen the set screw 11 and the locking screw 7, rotate the adjusting screw 6 to move the extended side beam 5 axially relative to the side beam cover 4 until scale 8 is in the correct position. Then tighten the set screw 11 and the locking screw 7 to fix the relative position of the extended side beam 5 and the side beam cover 4.

[0037] To determine if the position of scale 8 is correct, measure the distance between the extended edge beam 5 and the cutting edge of the cutting wheel of the cutting machine with a ruler, and see if the value is the same as the reading on scale 8. If they are the same, the position of scale 8 is accurate.
