Description

Technical Field

[0001] This utility model relates to the field of boundary opener technology, and in particular to a novel boundary opener. Background Technology

[0002] As a key tool for cutting and processing slabs such as tiles and stone, the cutting tool is widely used in the fields of building decoration and material processing. Its function is to precisely cut slabs into the required size and shape according to preset requirements. However, in actual use, traditional cutting tools have gradually revealed a series of problems that cannot be ignored.

[0003] In the process of tile processing, users of traditional tile cutters need to apply continuous force throughout the operation, which is difficult to control and can easily lead to damaged tiles. This not only results in direct waste of materials, but also requires additional purchase and transportation of tiles, delays the construction progress, and increases the overall cost of the project, causing unnecessary economic burden. Utility Model Content

[0004] The purpose of this invention is to provide a novel boundary opener to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution, which includes a C-shaped main housing, a handle provided on the back of the C-shaped main housing, an installation groove provided in the top plate of the C-shaped main housing, a pair of transmission components symmetrically arranged in the installation groove, and a pressing component provided between the two pairs of transmission components.

[0006] As a preferred embodiment of this utility model, a guide opening is provided on the back plate of the C-shaped main housing, and an inverted C-shaped groove is provided on the bottom plate of the C-shaped main housing, with a top column provided in the inverted C-shaped groove.

[0007] As a preferred embodiment of the present invention, the transmission assembly includes a pair of mounting plates, which are symmetrically arranged on the top and bottom surfaces of the mounting groove. Each mounting plate contains a pair of bearings, and a first lead screw is movably arranged between the corresponding two bearings.

[0008] As a preferred embodiment of this utility model, the pressing assembly includes a second lead screw threaded between four first lead screws, a handle at the top of the second lead screw, a fixed plate at the bottom of the second lead screw, a pressure head movably disposed at the bottom of the second lead screw, a limit block at the top of the pressure head, a mounting groove at the top of the limit block, the fixed plate disposed in the mounting groove, and the tail of the limit block fitting against the inner wall of the guide opening.

[0009] As a preferred embodiment of this utility model, the pressure head is provided with a pointer corresponding to the position of the top column.

[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0011] 1. This utility model uses a screw drive design, in which the first screw in the transmission component cooperates with the second screw in the pressing component. When the operator turns the handle, the second screw moves downward under the action of the thread. With the synchronous cooperation of the four first screws, the rolling friction is greatly reduced in this process, making the pressing process easier and smoother. Compared with the traditional tile opener, this device can more easily control the pressing force. This labor-saving operation method not only improves work efficiency, but also reduces the damage rate of tiles. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] like Figures 1-9 As shown, the present invention proposes a novel boundary opener, which includes a C-shaped main housing 1, a handle 5 on the back of the C-shaped main housing 1, a guide opening 12 on the back plate of the C-shaped main housing 1 to ensure that the pressure head 33 can press down vertically, and an inverted C-shaped groove 11 on the bottom plate of the C-shaped main housing 1. A top post 4 is installed in the inverted C-shaped groove 11. The top post 4 serves as a support to provide stable support force for the downward pressure. Its cooperation with the inverted C-shaped groove 11 makes the installation of the top post 4 firm and easy to maintain.

[0024] The mounting groove 10 inside the top plate of the C-shaped main housing 1 is provided with a pair of transmission components 2. The transmission components 2 are composed of a pair of mounting plates 20. These two mounting plates 20 are symmetrically arranged on the top and bottom surfaces of the mounting groove 10, respectively. Each mounting plate 20 is provided with a pair of bearings 21. Through the bearings 21, the first lead screw 22 can rotate flexibly. The first lead screw 22 is movably arranged between the corresponding two bearings 21. This installation method not only ensures the stable rotation of the first lead screw 22, but also enables the first lead screws 22 to work together. In actual operation, when the throttle 31 drives the second lead screw 30 to rotate, the first lead screw 22 can achieve precise transmission through the threaded engagement with the second lead screw 30.

[0025] The core component of the pressing assembly 3 is the second lead screw 30, which is threaded between the four first lead screws 22. A handle 31 is installed on the top of the second lead screw 30. The operator can easily control the lifting and lowering of the second lead screw 30 by turning the handle 31. A fixing plate 32 is provided at the bottom of the second lead screw 30. The fixing plate 32 is installed in the mounting groove 34 of the top limit block 36 of the pressing head 33. A pointer 35 is provided at the bottom of the pressing head 33 corresponding to the position of the top column 4.

[0026] In actual operation, the first step is to use a tile cutter to accurately mark the required cutting line on the surface of the tile; then, place one side of the tile steadily on the top column 4 of the equipment, and at the same time, adjust the position of the tile so that the pointer 35 on the equipment is aligned with the previously marked line.

[0027] Then, holding handle 5 with one hand, manually and evenly rotate handle 31 with the other hand. The rotation of handle 31 will drive several first lead screws 22 to work together. With their cooperation, the second lead screw 30, which is linked to the first lead screw 22, begins to move downward, which greatly reduces the rolling friction and makes the pressing process easier and smoother. At the same time, the pressure head 33, which is connected to the second lead screw 30, presses on both sides of the tile boundary during the downward process and continues to apply rotational force, making it easier to control the force. When the pressure applied by the pressure head 33 reaches a certain level, the tile can be easily pressed into two pieces along the pre-marked boundary. This design effectively reduces the force required to press the tile and improves efficiency through the coordinated operation of the mechanical structures, providing an efficient and convenient solution for tile processing.

[0028] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
