Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a brick cutter. Background Technology

[0002] Bricks are a common and important building material. Molded bricks can be used directly or after being cut and shaped by a brick cutter. For example, utility model patent CN220261517U provides an adjustable positioning brick cutting device, which includes: a support base; an L-shaped limiting plate disposed at the bottom of the support base; a limiting plate bolt passing through the support base and connected to the L-shaped limiting plate; a capped nut connected to the limiting plate bolt; and a cutting device disposed on the support base and slidably connected to the support base to apply a downward force to the cutting device, which then cuts the brick. This patent provides a portable and convenient brick cutting device for cutting bricks in different scenarios.

[0003] The patent description discloses that an L-shaped limiting plate is installed at the bottom of the support base and connected to the limiting plate bolt, serving to limit and position the cutting range and position of the cutting device. The limiting plate bolt connects the L-shaped limiting plate and the support base; tightening or loosening it adjusts the position of the limiting plate, thereby adjusting the cutting position. However, adjusting the position of the L-shaped limiting plate by tightening or loosening the limiting plate bolt requires workers to make trial adjustments based on their own judgment (estimating the approximate position) or to use measuring tools to measure and compare until the L-shaped limiting plate is precisely positioned at a specific position that can cut bricks of the required length before tightening and fixing it. This process of finding the right position is quite troublesome, and the cutting accuracy is difficult to guarantee. Summary of the Invention

[0004] The purpose of this invention is to develop a brick cutter to solve the problem of difficulty in quickly and accurately positioning existing brick cutters, thereby improving the convenience and accuracy of positioning.

[0005] This utility model is achieved through the following technical solution:

[0006] A brick cutter includes a grip frame, a base connected to the grip frame, and a brick cutting assembly connected to one side of the grip frame for cutting bricks. The base is provided with a positioning adjustment assembly, which includes a positioning plate whose position is adjustable relative to the brick cutting assembly. The surface of the base is provided with a scale portion, which includes scale lines distributed laterally along the surface of the base. The positioning adjustment assembly also includes an adjustment screw, which rotates to drive the positioning plate to move laterally along the scale portion of the base, thereby moving closer to or away from the brick cutting assembly.

[0007] The beneficial effects of the above technical solution are as follows: The base surface of this brick cutter is provided with horizontally distributed scale sections, and the positioning plate is driven to move laterally along the scale sections of the brick cutter base by adjusting the screw rotation, thereby moving closer to or further away from the brick cutting component; Compared with manually moving the positioning plate directly, the screw rotation drives the positioning plate to move laterally, making the moving speed of the positioning plate uniform and controllable, and the position of the positioning plate can be judged according to the scale lines when the positioning plate moves, which makes it convenient to quickly and accurately find the position of the positioning plate in order to determine the cutting position of the brick cutting component, thereby improving the convenience and accuracy of positioning the brick cutter.

[0008] In one possible implementation, the positioning adjustment assembly further includes an adjustment wheel connected to the adjustment end of the adjustment screw, and the rotation of the adjustment wheel drives the adjustment screw to rotate, which facilitates operation.

[0009] In one possible implementation, the base has a laterally extending hollow cavity for accommodating the adjusting screw, and a laterally extending transverse groove is provided on the base corresponding to the position of the hollow cavity. The positioning plate includes a positioning part located inside the hollow cavity and a baffle located outside the hollow cavity. The positioning part is sleeved on the adjusting screw and drivesly engages with the adjusting screw. The baffle and the positioning part are connected by a connecting part that passes through the transverse groove. The positioning plate is laterally slidable and limited within the transverse groove, so that the baffle can only be laterally displaced along the scale portion. The transverse groove limits the positioning plate and guides its movement through the connecting part.

[0010] Furthermore, a nut seat is connected to one side of the positioning part, and the nut seat is sleeved on the adjusting screw to facilitate a stable connection between the positioning part and the adjusting screw.

[0011] Furthermore, the scale is located on the side of the base, and the horizontal groove is opened at the bottom of the base. This layout makes it easy to read the scale, and the baffle extends out of the horizontal groove at the bottom of the base, which is located just below the base, so that it can cooperate with the brick.

[0012] In one possible implementation, the grip is C-shaped, and both the grip and the base are hollow tubular components. The grip and the base are welded together to form a right-angled trapezoid or rectangular frame, such that the brick-cutting component connected to the right-angled side of the grip is perpendicular to the scale portion on the base. The hollow tubular components are welded together to meet the requirements of lightweight design, and the resulting right-angled trapezoid or rectangular frame has right-angled sides, such that the brick-cutting component connected to the right-angled side of the grip is perpendicular to the scale portion on the base.

[0013] In one possible implementation, the brick-cutting assembly includes a C-shaped cutter holder, a cutter handle, and a cutter blade connected thereto. The cutter holder has polygonal through holes at both its upper and lower ends for the cutter handle to pass through and for circumferentially and radially limiting the cutter handle. A return spring is fitted around the outer periphery of the cutter handle, and a limiting pin passes through the cutter handle. The return spring is positioned between the limiting pin and the cutter holder. The limiting pin limits the vertical (i.e., axial) sliding stroke of the cutter handle within the cutter holder, and the return spring pushes against the limiting pin, thereby causing the cutter handle to return to its original position.

[0014] In one possible implementation, a non-metallic sound-absorbing cap is provided on the top of the cutter handle to reduce the noise generated when the cutter handle is hammered. Attached Figure Description

[0024] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments are described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, this embodiment provides a brick cutter, including a gripping frame 1, a base 2 connected to the gripping frame 1, and a brick cutting assembly 5 connected to one side of the gripping frame 1 for cutting bricks. The base 2 is provided with a positioning adjustment assembly 4, which includes a positioning plate 41 whose position is adjustable relative to the brick cutting assembly 5. The surface of the base 2 is provided with a scale portion 3, which includes scale lines distributed laterally along the surface of the base 2. The positioning adjustment assembly 4 also includes an adjusting screw 43, which rotates to drive the positioning plate 41 to move laterally along the scale portion 3 of the base 2, thereby moving closer to or away from the brick cutting assembly 5.

[0026] Furthermore, the positioning adjustment assembly 4 also includes an adjustment wheel 42, which is connected to the adjustment end 431 of the adjustment screw 43, and the adjustment wheel 42 rotates to drive the adjustment screw 43 to rotate; the adjustment end 431 is located on the lateral outer side of the base, so that the adjustment wheel 42 is located on the lateral outer side of the base, and the adjustment wheel 42 is positioned on the adjustment end 431 of the adjustment screw 43 by the first limiting washer 441 and the second limiting washer 442 on both sides of it, and the first limiting washer 441 is positioned by the snap ring 45; similarly, the end of the adjustment screw 43 away from the adjustment end 431 is provided with a third limiting washer and a snap ring adapted thereto, and is positioned on the base 2.

[0027] In use, the worker manually rotates the adjusting wheel 42 to drive the adjusting screw to rotate, which in turn drives the positioning plate to move laterally along the scale section of the brick cutter base, moving closer to or away from the brick cutting assembly. After the positioning plate contacts the edge of the brick, it strikes the cutting assembly to cut the brick. During the rotation of the adjusting wheel 42, the position of the positioning plate can be determined according to the scale lines, which facilitates quick and accurate adjustment to accurately position the cutting position of the brick cutting assembly, improving the convenience and accuracy of the brick cutter's positioning.

[0028] In one embodiment, the base 2 has a laterally extending hollow cavity for accommodating the adjusting screw 43, and a laterally extending transverse groove is provided on the base 2 corresponding to the position of the hollow cavity.

[0031] In one embodiment, the grip 1 is C-shaped, and both the grip 1 and the base 2 are hollow tubular components. The grip 1 and the base 2 are welded together to form a right-angled trapezoid or rectangular frame, such that the brick-cutting component 5 connected to the right-angled side of the grip 1 is perpendicular to the scale portion 3 on the base 2. The hollow tubular components are welded together to meet the requirements of lightweight design, and the formed right-angled trapezoid or rectangular frame has right-angled sides, such that the brick-cutting component 5 connected to the right-angled side of the grip 1 is perpendicular to the scale portion 3 on the base 2.

[0032] In one embodiment, the brick-cutting assembly 5 includes a C-shaped cutter seat 54, a cutter handle 51, and a cutter blade 52 connected thereto. The cutter seat 54 has polygonal through holes at both its upper and lower ends for the cutter handle 51 to pass through and to limit the circumferential and radial movement of the cutter handle 51. A return spring 53 is sleeved on the outer periphery of the cutter handle 51, and a limiting pin 55 passes through the cutter handle 51. The return spring 53 is located between the limiting pin 55 and the cutter seat 54. The limiting pin 55 limits the vertical (cutter handle axial) sliding stroke of the cutter handle 51 in the cutter seat 54, and the return spring 53 is used to push the limiting pin 55 to drive the cutter handle 51 to return to its original position.

[0033] In one embodiment, a non-metallic sound-absorbing cap 56 is provided on the top of the cutter handle 51 to reduce the noise generated when the cutter handle is hammered.
