Description

Technical Field

[0001] The utility model relates to the field of cutting tiles or plates, and more specifically, it relates to a cutting machine. Background Technique

[0002] Tile cutting machines are divided into two categories: manual operation and electric operation. For example, light professional tile cutters are made of lightweight aluminum alloy materials to make them suitable for manual use, thus conveniently meeting the needs of professional users.

[0003] For example, a tile cutting machine disclosed in the utility model patent with the publication number CN213563635U applied by the applicant, or a single-rail enhanced tile cutting machine disclosed in the invention patent with the publication number CN105437383B. Both of these two cutting machines adopt lightweight structures.

[0004] In order to reduce the friction between the handle and the cross beam during the pushing process in the above-mentioned prior art, a bearing assembly is arranged inside the handle to achieve this. Specifically, reference can be made to a bearing device disclosed in CN 217098365U of the applicant. There are also many structures on the market, but currently there is no locking structure for the handle in a static state. That is, when the cutting machine is being transported, affected by the rolling contact of the bearing assembly, the handle will run; moreover, the currently arranged bearing assembly is realized by installing multiple bearings, and this kind of installation makes the handle inconvenient to assemble. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a cutting machine with a reasonable and simple structure, strong practicability, and capable of locking the handle at any position where it slides on the cross beam.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A cutting machine includes a base and two support components respectively arranged at both ends of the base. A cross beam is connected between the two support components. A cutting assembly that can slide relative to the cross beam is installed on the cross beam. A stop structure for locking the handle of the cutting assembly at any position on the cross beam is provided on the handle of the cutting assembly.

[0008] The stop structure includes a dial and a locking tongue. The locking tongue has two symmetric limiting parts. The inner walls of the two limiting parts respectively abut against the two outer side walls of the cross beam, so that the limiting parts and the cross beam rub against each other, thereby locking the position of the cutting assembly on the cross beam.

[0009] The paddle is placed on the outer wall of the handle, the lock tongue is placed inside the handle, one end of the paddle is connected to one side of the lock tongue, and the other side of the lock tongue is rotatably connected to the handle, so that the paddle is pushed to rotate synchronously with the lock tongue, so that the limiting part and the crossbeam are separated, and the cutting assembly can slide freely on the crossbeam;

[0010] A bearing piece is also arranged in the handle, and the bearing piece is sleeved outside the cross beam, and the movable end of the bearing piece rolls against the cross beam.

[0011] The utility model is further configured as follows: a plug-in portion is provided on the connecting end of the paddle and the lock tongue, the plug-in portion is square, the lock tongue has a receiving groove for the plug-in portion to extend into, the paddle extends into the receiving groove through the plug-in portion, and then is fixed by a screw rod penetrating the plug-in portion and the lock tongue;

[0012] The side of the lock tongue facing away from the plug-in portion is rotatably connected with the handle via a pin shaft.

[0013] The utility model is further configured as follows: a pressure ruler is arranged on the base, and a guide ruler which can slide on the main body of the pressure ruler is also arranged on the pressure ruler.

[0014] The utility model is further configured as follows: an adjustment portion is provided on one side of the pressure ruler, a movable opening is opened on the adjustment portion, an angle scale is engraved on the outer side of the movable opening, a locking bolt is provided on the movable opening, and the output end of the locking bolt is in contact with the base so as to rotate the pressure ruler to the cutting angle and lock it.

[0015] The utility model is further configured as follows: a caster is installed on one of the supporting components, a laser light is also installed on the supporting component, and a handle is installed on the other supporting component.

[0016] The utility model is further configured as follows: foldable supporting feet are provided on both sides of the base.

[0017] Compared with the shortcomings of the prior art, the beneficial effects of the utility model are:

[0018] By arranging a stop structure on the handle, the handle can be positioned and locked when it moves on the beam. The stop structure has a simple structure and is very convenient to use. The handle position can be locked and the handle can slide freely on the beam by simply moving the paddle with a finger. BRIEF DESCRIPTION OF THE DRAWINGS
