Abstract
Description
Technical Field
[0001] This utility model relates to the field of interior decoration technology, and in particular to a wall grooving device with adjustable width. Background Technology
[0002] Wall grooving plays a crucial role in home renovation. It primarily protects and conceals pipes and wiring, extending their lifespan and making electrical and plumbing work more standardized, aesthetically pleasing, and streamlined. By embedding electrical wires or water pipes within the wall through grooving, they are prevented from being exposed, reducing the risk of damage and extending their lifespan. Furthermore, the grooved pipe layout is more organized and conforms to building codes, resulting in a cleaner and more attractive wall appearance. Although the pipes are buried, proper grooving design and marking facilitate future inspection and maintenance. Grooving is typically performed by workers using grooving machines; however, most grooving machines on the market have fixed groove widths, making it inconvenient to carry multiple machines for projects involving various pipes.
[0003] A search revealed Chinese patent publication number CN220335671U, which discloses an adjustable-width slotted assembly for municipal engineering, comprising a first support plate, a mounting plate, a ball screw, a first coupling, a nut for the screw, a moving plate, a guide shaft, a cutting assembly, and a support assembly. During use, controlling the rotation of either ball screw on one side, via the first coupling, will drive the other ball screw to rotate synchronously.
[0004] To address the problem that the aforementioned technology can only adjust the width between two saw blades, requiring repeated hammering of the wall surface after cutting to complete the grooving, which results in a very large amount of hammering work and is quite cumbersome when the width is large, a wall grooving device with adjustable width is proposed. Utility Model Content
[0005] In view of this, the present invention aims to provide a wall grooving device with adjustable width to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.
[0006] The technical solution of this utility model embodiment is implemented as follows: a main unit with a drive component fixedly connected to one side, an adjustment shaft rotatably connected to one end of the main unit, a central guide groove and multiple adjustment guide grooves at one end of the adjustment shaft, multiple adjustment brackets rotatably connected to the outer side of the adjustment shaft, rollers rotatably connected to the inner side of the adjustment brackets, corresponding rollers movably connected to one side of the central guide groove and the adjustment guide grooves, a saw blade mounting assembly fixedly connected to the other end of the adjustment brackets, a cutting saw blade fixedly connected to one end of the saw blade mounting assembly, a drive shaft fixedly connected to one end of the cutting saw blade, and a drive shaft fixedly connected to one end of the drive shaft at the power output end of the drive component.
[0007] In some embodiments, the saw blade mounting assembly includes a saw blade bracket one, a saw blade bracket two, a bearing two, and a connecting boss.

One end of the saw blade bracket one or the saw blade bracket two is fixedly connected to the bearing two, and one end of the cutting saw blade is fixedly connected to the inner side of the bearing two.
[0008] In some embodiments, a limit rod is fixedly connected to one side of the main unit, and multiple adjustment brackets are slidably connected to the limit rod.
[0009] In some embodiments, a protective shell is fixedly connected to one end of the limiting rod and the main unit, and a side guard plate is rotatably connected to one end of the protective shell.
[0010] In some embodiments, a bearing housing is bolted to one end of the side guard plate, and a bearing is fixedly connected inside the bearing housing. The bearing is fixedly connected to one end of the drive shaft by a mounting nut.
[0011] In some embodiments, an adjustment knob is rotatably connected to one side of the protective shell, and one end of the adjustment knob is fixedly connected to the adjustment shaft.
[0012] In some embodiments, one end of the adjustment knob has multiple positioning holes, and one end of each positioning hole is slidably connected to a knob positioning pin.
[0013] In some embodiments, a positioning bracket is fixedly connected to one end of the protective shell, and a spring is fixedly connected to one end of the positioning bracket and the knob positioning pin, while the other end of the knob positioning pin is slidably connected inside the positioning bracket.
[0014] The present invention has the following advantages due to the adoption of the above technical solution:
[0015] 1. A wall grooving device with adjustable width, wherein rotating the adjusting shaft counterclockwise causes the adjusting guide grooves on both sides to move by driving the corresponding rollers, which in turn causes the adjusting brackets corresponding to the rollers to move the position of the cutting saw blades below, thus adjusting the width of the cut groove. The number of adjusting guide grooves on both sides can be changed as needed. Preferably, the device can drive five cutting saw blades to work simultaneously, which makes it easier to chisel the cement in the groove after cutting the wall, reducing the labor intensity of workers and improving construction efficiency.
[0016] 2. A wall grooving device with adjustable width, wherein different spacing between multiple positioning holes at one end of the adjustment knob corresponds to different grooving widths. When it is necessary to change the grooving width, simply rotate the adjustment knob and then insert the knob positioning pin into the positioning hole and the opening on one side of the protective shell to fix the adjustment knob, thereby changing the cutting width.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0028] Example 1:
[0029] like Figure 1-5 As shown, a wall grooving device with adjustable width includes a main unit 1 with a drive component 2 fixedly connected to one side. The main unit 1 contains control components, power supply components, and heat dissipation components for control, which can control the operation of the motor in the drive component 2. An adjustment shaft 16 is rotatably connected to one end of the main unit 1. One end of the adjustment shaft 16 has a central guide groove 23 and multiple adjustment guide grooves 22. Multiple adjustment brackets 15 are rotatably connected to the outside of the adjustment shaft 16. Rollers 21 are rotatably connected to the inside of the adjustment brackets 15. Corresponding rollers 21 are movably connected to one side of the central guide groove 23 and the adjustment guide grooves 22, respectively. A saw blade mounting assembly is fixedly connected to the other end of the adjustment bracket 15. A cutting saw blade 6 is fixedly connected to one end of the saw blade mounting assembly. A drive shaft 5 is fixedly connected to one end of the cutting saw blade 6. One end of the drive shaft 5 is fixedly connected to the power output end of the drive component 2.
[0030] The drive unit 2 can drive multiple cutting saw blades 6 to rotate simultaneously via the drive shaft 5 for cutting. When it is necessary to adjust the groove width, the adjustment shaft 16 can be rotated counterclockwise. At this time, the adjustment guide grooves 22 on both sides can drive the corresponding rollers 21 to move, so that the adjustment brackets 15 corresponding to the rollers 21 can drive the cutting saw blades 6 below to move and adjust the width of the cut groove. The number of adjustment guide grooves 22 on both sides can be changed as needed. The preferred device can drive five cutting saw blades 6 to work at the same time, which makes it easier to chisel the cement in the groove after cutting the wall, reducing the labor intensity of workers and improving construction efficiency.
[0031] In this embodiment, the saw blade mounting assembly includes a saw blade bracket 18, a saw blade bracket 29, a bearing 20, and a connecting boss 24. One end of the connecting boss 24 is fixedly connected to the adjusting bracket 15. The saw blade bracket 18 and the saw blade bracket 29 are fixedly connected to the connecting boss 24 by bolts. One end of the saw blade bracket 18 or the saw blade bracket 29 is fixedly connected to the bearing 20, and one end of the cutting saw blade 6 is fixedly connected to the inner side of the bearing 20.
[0032] The saw blade 6 is fixed in position from both sides by saw blade bracket 18 and saw blade bracket 29 in conjunction with bearing 20 to prevent it from shaking during operation.
[0033] In this embodiment, a limiting rod 17 is fixedly connected to one side of the host 1, and multiple adjusting brackets 15 are slidably connected to the limiting rod 17. The limiting rod 17 can prevent the adjusting brackets 15 from deflecting when the adjusting shaft 16 rotates, and at the same time provide support for the adjusting brackets 15 and the saw blade mounting assembly during cutting.
[0034] In this embodiment, a protective shell 3 is fixedly connected to one end of the limiting rod 17 and the main unit 1, and a side guard plate 4 is rotatably connected to one end of the protective shell 3. The protective shell 3 can be used to protect the internal mechanism, and the side guard plate 4 can be fixed by bolts.
[0035] In this embodiment: the drive component 2 can drive multiple cutting saw blades 6 to rotate simultaneously through the drive shaft 5 for cutting. When it is necessary to adjust the groove width, the adjustment shaft 16 can be rotated counterclockwise. At this time, the adjustment guide grooves 22 on both sides can drive the corresponding rollers 21 to move, so that the adjustment brackets 15 corresponding to the rollers 21 can drive the cutting saw blades 6 below to move and adjust the width of the cut groove. The number of adjustment guide grooves 22 on both sides can be changed as needed. The preferred device can drive five cutting saw blades 6 to work at the same time, which makes it easier to chisel the cement in the groove after cutting the wall, reducing the labor intensity of workers and improving construction efficiency.
[0036] The saw blade 6 is fixed from both sides by saw blade bracket 18 and saw blade bracket 29 in conjunction with bearing 20 to prevent it from shaking during operation.
[0037] The limit rod 17 prevents the adjusting bracket 15 from deflecting when the adjusting shaft 16 rotates, and at the same time provides support for the adjusting bracket 15 and the saw blade mounting assembly during cutting.
[0038] Example 2:
[0039] An adjustable-width wall grooving device is provided in this embodiment, which is improved upon embodiment 1 as follows: Figure 1-5 As shown,
[0040] In this embodiment, a bearing seat 10 is bolted to one end of the side guard plate 4, and a bearing 9 is fixedly connected inside the bearing seat 10. The bearing 9 and one end of the drive shaft 5 are fixedly connected by a mounting nut 11. When it is necessary to disassemble and replace the saw blade, the mounting nut 11 can be removed first to unlock the drive shaft 5 and the bearing 9. Then the bearing seat 10 can be removed from the side guard plate 4, and then the side guard plate 4 can be opened to replace the cutting saw blade 6.
[0041] In this embodiment, an adjustment knob 7 is rotatably connected to one side of the protective shell 3. One end of the adjustment knob 7 is fixedly connected to the adjustment shaft 16. Multiple positioning holes 8 are opened at one end of the adjustment knob 7. An opening of the same size as the positioning holes 8 is opened on one side of the protective shell 3. A knob positioning pin 13 is slidably connected to one end of the positioning hole 8. A positioning bracket 12 is fixedly connected to one end of the protective shell 3. A spring 14 is fixedly connected to one end of the positioning bracket 12 and the knob positioning pin 13. The other end of the knob positioning pin 13 is slidably connected inside the positioning bracket 12.
[0042] The different spacing between the multiple positioning holes 8 at one end of the adjustment knob 7 corresponds to different slot widths. When it is necessary to change the slot width, simply rotate the adjustment knob 7 and then insert the knob positioning pin 13 into the positioning hole 8 and the opening on one side of the protective shell 3 to fix the adjustment knob 7, thereby changing the cutting width. The spring 14 can prevent the knob positioning pin 13 from falling off due to vibration during operation.
