Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated bathroom construction, and more specifically, to a grinding device for the backing keel of prefabricated bathroom wall panels. Background Technology
[0002] In the field of prefabricated buildings, especially in the construction of integrated bathrooms, prefabricated wall panels and metal-backed keel structures are widely used. During transportation, storage, or installation, the surface of these keels often becomes rusted or has impurities attached. To ensure the quality of subsequent waterproofing and decorative layer construction, they must be thoroughly sanded before installation. Currently, this process generally relies on construction workers using handheld angle grinders to work at heights. This traditional manual method has significant drawbacks. First, the construction efficiency is extremely low, and the sanding quality is inconsistent, heavily reliant on the worker's personal experience and physical strength, easily leading to missed areas or excessive material waste. Second, the intense vibrations and reaction forces generated during operation are entirely borne by the worker's arm, resulting in high labor intensity, significant muscle strain, and safety hazards. Furthermore, the complex construction site environment and difficulty in finding temporary stable support points further exacerbate the instability and risk of the operation.
[0003] Currently, while some large, stationary grinding equipment exists on the market, its high cost and inconvenience in moving it make it unsuitable for the flexible and efficient operational needs of construction sites. Meanwhile, simple auxiliary tools often lack effective support and guiding mechanisms, failing to fundamentally address these issues. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, this utility model provides a prefabricated bathroom wall panel backing keel grinding device. This device features a simple structure, low cost, and ease of manufacture and reuse. It effectively fixes the angle grinder, providing stable sliding support, significantly reducing operational difficulty and labor intensity, and improving grinding efficiency and quality uniformity, thus meeting the dual demands of efficiency and safety in modern construction.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A prefabricated bathroom wall panel backing keel grinding device includes an arched frame, a rod, a first sliding component, a second sliding component, a first connector, a second connector, a fastening component, and a wire fixing component. The rod is fixedly connected to the end of the arched frame. The first sliding component is disposed at the left front end of the arched frame via the first connector. The second sliding component is disposed at the right front end of the arched frame via the second connector. The fastening component is disposed in the middle of the arched frame for fixing an angle grinder. The wire fixing component is fixedly disposed on the outer wall of the rod.
[0006] Both the first sliding component and the second sliding component adopt a roller structure, and the first sliding component and the second sliding component are mounted on the corresponding first connector and second connector via a rotating shaft.
[0007] The fastening assembly uses a bolt structure, with the bolts passing through mounting holes on the bow-shaped frame and tightened to clamp and fix the angle grinder.
[0008] The bow-shaped frame is integrally bent from a metal strip, and the rod is made of a round tube. The top end of the rod is fixedly connected to the end of the bow-shaped frame by welding.
[0009] The outer ring surfaces of the first sliding component and the second sliding component protrude beyond the contours of the first connector and the second connector, and are used to form line contact with the surface to be polished to reduce friction.
[0010] The lateral spacing between the bow-shaped frames can be adjusted to fit the size of the backing keel to be polished.
[0011] The wire fixing component is a wire buckle or cable tie.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The device creatively adopts an arched frame main structure and sets symmetrical sliding components at the end. This structure allows the angle grinder to be firmly fixed, and the operator only needs to push the device to make the sliding components roll smoothly along the keel surface. This transforms the traditional heavy hand operation into a labor-saving pushing operation, which greatly reduces the operator's labor intensity and skill threshold, while effectively avoiding the problem of uneven grinding caused by arm fatigue.
[0013] The modular and adjustable design of the device further enhances its application value. The fastening components provide a simple and reliable way to secure tools, are easy to install and disassemble, and are adaptable to different models of angle grinders. The spacing between the bow-shaped frames can be flexibly adjusted according to actual working conditions, enhancing the device's adaptability to different specifications of keels. The overall structure is mainly made of common metal materials through simple welding or bending processes, without complex parts, resulting in extremely low manufacturing costs and easy on-site processing using readily available materials, demonstrating excellent practicality and economy.
[0014] Furthermore, the device demonstrates excellent safety and ease of use. The sliding assembly effectively transmits and counteracts vibrations and reaction forces generated during angle grinder operation, improving operational stability. Optional power cord securing components facilitate power cord management and reduce safety hazards during on-site operations.
[0015] With its simple yet efficient structure, this device has successfully achieved multiple beneficial effects, including improving grinding efficiency, ensuring work quality, reducing construction costs, and guaranteeing operational safety. It has strong promotional value and market competitiveness. Attached Figure Description

Detailed Implementation
[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0019] like Figures 1 to 4 As shown, a prefabricated bathroom wall panel backing keel grinding device includes an arched frame 1, a rod 2, a first sliding component 3, a second sliding component 4, a first connector 5, a second connector 6, a fastening component 7, and a wire fixing component 8. The rod 2 is fixedly connected to the end of the arched frame 1. The first sliding component 3 is set at the left front end of the arched frame 1 through the first connector 5. The second sliding component 4 is set at the right front end of the arched frame 1 through the second connector 6. The fastening component 7 is set in the middle part of the arched frame 1 for fixing an angle grinder. The wire fixing component 8 is fixedly set on the outer wall of the rod 2. First, take an iron bar and bend it into an arched frame 1 with an arc-shaped handle at the top and straight sections on both sides. Subsequently, the round tube of rod 2 is vertically welded to the end of the bow frame 1 to ensure it is secure. After installing the first sliding component 3 and the second sliding component 4 on the first connector 5 and the second connector 6, they are welded to the inner front end of the bow frame 1 respectively, and the axes of the two rollers are made parallel. A hole is drilled at the center of the arc of the bow frame 1, and a fastening component 7 is inserted. A wire buckle is connected to the side of rod 2 as a wire fixing component 8.
[0020] Preferably, both the first sliding component 3 and the second sliding component 4 adopt a roller structure. The first sliding component 3 and the second sliding component 4 are mounted on the corresponding first connecting member 5 and the second connecting member 6 via a rotating shaft. First, pin holes are drilled on the first connecting member 5 and the second connecting member 6. Then, a smooth steel rotating shaft is passed through the inner hole of the roller, and both ends of the rotating shaft are pressed into or welded into the pin holes, thereby reliably mounting the roller on the first connecting member 5 and the second connecting member 6 so that it can rotate flexibly.
[0021] Preferably, the fastening component 7 adopts a bolt structure. The bolt passes through the mounting hole opened on the bow-shaped frame 1 and is tightened to clamp and fix the angle grinder. When fixing the angle grinder, the operator places the hand-held part of the angle grinder inside the bow-shaped frame 1, so that the bolt of the fastening component 7 passes through the hole of the bow-shaped frame 1 on the neck side of the angle grinder. Then, a washer is put on the other end of the bolt and tightened. By continuously tightening, the angle grinder body is pressed, so that it is firmly clamped between the bow-shaped frames 1.
[0022] Preferably, the bow-shaped frame 1 is integrally bent from a metal strip, and the rod 2 is made of a round tube. The top end of the rod 2 is fixedly connected to the end of the bow-shaped frame 1 by welding, so that a complete iron strip is cold-bent into the designed bow-shaped frame 1 shape, avoiding segmented welding.
[0023] Preferably, the outer ring surfaces of the first sliding component 3 and the second sliding component 4 protrude beyond the contours of the first connector 5 and the second connector 6 to form line contact with the surface to be polished to reduce friction. When welding the first connector 5 and the second connector 6, the installation position of the roller is slightly off to the outside to ensure that the highest point of the outer ring of the roller protrudes outward by a few millimeters more than the plane of the first connector 5 and the second connector 6.
[0024] Preferably, the lateral spacing between the bow-shaped frames 1 can be adjusted to fit the size of the backing keel to be ground. By providing several different widths of the device, it can adapt to various working conditions on site without the need to manufacture a complex adjustable mechanism.
[0025] Preferably, the wire fixing component 8 is a wire buckle or cable tie. When in use, the power cord of the angle grinder is wrapped around the buckle one or two times and then inserted into the buckle's slot.
[0026] Before use, this utility model requires assembly. The operator takes a metal strip of suitable length and bends it to form an arched frame 1. Then, the operator fixes the top end of the rod 2 to the end of the arched frame 1 by welding, so that the rod 2 extends downward in parallel.
[0027] Next, the operator needs to install the sliding components. The rotating shafts are installed on the first connecting piece 5 and the second connecting piece 6 respectively, and the rollers of the first sliding component 3 and the second sliding component 4 are fitted onto their respective rotating shafts, ensuring the rollers can rotate freely. Then, the first connecting piece 5, with the first sliding component 3 assembled, is welded to the inner side of the front left end of the bow-shaped frame 1, and the second connecting piece 6, with the second sliding component 4 assembled, is welded to the inner side of the front right end of the bow-shaped frame 1. The outer surfaces of the rollers of the first sliding component 3 and the second sliding component 4 slightly protrude from the contours of the first connecting piece 5 and the second connecting piece 6, and their positions are symmetrical.
[0028] Then, the operator inserts the screw of the fastening component 7 into the pre-drilled mounting hole at the bottom of the bow-shaped frame 1, places the handle of the angle grinder inside the bow-shaped frame 1, and surrounds the screw around it. Finally, the operator tightens the nut of the fastening component 7 at the end of the screw. Tightening the nut causes the clamping device to reliably clamp and fix the angle grinder onto the bow-shaped frame 1. After completion, the operator can loosely fix the power cord of the angle grinder to the bow-shaped frame 1 using the wire fixing component 8, such as a wire clip, to prevent the power cord from dragging and affecting operation.
[0029] Upon entering the construction site, the operator holds the device and connects the angle grinder to the power supply. During operation, the operator holds the middle grip of lever 2 with one hand, tilting the device slightly so that the rollers of the first sliding component 3 and the second sliding component 4 simultaneously contact the surface of the keel to be ground. After starting the angle grinder, the operator does not need to press down forcefully; simply push the entire device smoothly along the length of the keel. At this time, the first sliding component 3 and the second sliding component 4 will roll on the keel surface, guiding the grinding discs of the angle grinder to perform uniform and efficient grinding. If keels of different widths need to be ground, the operator can prefabricate multiple devices with different lateral spacings, i.e., by adjusting the width between the bow-shaped frames 1 to adapt to different working conditions. The entire device has a simple structure, is easy to maintain after use, and all components can withstand the harsh environment of the construction site.
[0030] The above description only details the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
