[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A foaming strip with good installation effect includes a body 1 and an auxiliary component 3. The body 1 has a magnetic absorbing piece 2 on one side, which is fixedly connected to the body 1. The auxiliary component 3 includes a frame 4, sandpaper 5, a cavity, a liquid dispensing component 6, an iron plate 7, and bolts 8. The frame 4 is fitted outside the body 1. The sandpaper 5 is placed on the frame 4 and fixedly connected to the frame 4. The cavity is opened in the frame 4. The liquid dispensing component 6 is placed on one side of the frame 4 and communicates with the interior of the cavity. The cavity contains alcohol. The iron plate 7 is connected to the frame 4 by the bolts 8. One side of the iron plate 7 is in contact with the magnetic absorbing piece 2, and the magnetic absorbing piece 2 attracts the iron plate 7.

[0026] In this embodiment, the worker first uses a screwdriver to loosen and remove the bolts 8, thereby detaching the iron plate 7 from the frame 4. Then, the worker applies force by holding the handle 9 to pull the iron plate 7, causing the iron plate 7 to separate from the magnetic piece 2, thus completing the disassembly of the auxiliary component 3.

[0027] Non-metallic surface mounting steps:

[0028] Surface roughening treatment: Hold the frame 4 and attach the sandpaper 5 to the surface of the non-metallic object. Reciprocate the sanding at a speed of 50-100mm / s to make the surface roughness reach Ra3.2-6.3μm (detected by a roughness tester), forming dense micro-anchor points to enhance the mechanical bonding ability of the glue.

[0029] Dust removal: Use a lint-free cloth to remove debris from sanding, ensuring no visible particles remain on the surface;

[0030] Oil stain cleaning: By opening the liquid dispensing component, the alcohol in the cavity flows to the polishing area. Using a degreasing cotton ball, wipe in one direction to remove surface grease and chemical residues, ensuring the surface contact angle is <30° (verified by a contact angle measuring instrument).

[0031] Adhesive fixing: Apply acrylic structural adhesive evenly to the surface of magnetic sheet 2, with the adhesive layer thickness controlled at 0.1-0.15mm (use a dispensing machine to ensure accuracy). Align with the pre-treated installation position, apply 0.5-1kgf pressure and hold for 30 seconds to ensure full contact between the adhesive layer and the surface. After curing at room temperature for 24 hours, the optimal bonding strength (shear strength ≥15MPa) will be achieved.

[0032] Metal surface mounting steps:

[0033] Ensure that the frame and the body are also separated. Hold the frame 4 and open the liquid dispensing component to let the alcohol in the cavity flow to the area where it needs to be installed. Use a microfiber cloth to wipe the metal surface to remove oil and oxide film, so that the surface resistivity is <10Ω·cm.

[0034] Align the main body 1 with the metal substrate, and utilize the magnetic attraction force (≥5N / cm) between the magnetic absorbing sheet 2 (surface magnetic field strength ≥50mT) and the metal surface. 2 Rapid adsorption is achieved, and the installation position deviation is ensured to be ≤0.5mm by the guiding structure of frame 4 during the adsorption process;

[0035] Key parameter control:

[0036] The thickness of the magnetic accumulator 2 is strictly controlled between 0.1-0.2mm. Combined with the elastic compression of the main body (compression rate 15%-20%), the installation gap is ≤0.3mm. According to the feeler gauge test, the average gap of the metal surface is 0.22mm, and the uniformity error of the adhesive layer thickness on the non-metallic surface is ≤±5%.

[0037] After auxiliary components are used up, they can be centrally recycled and returned to the manufacturer. By establishing a standardized recycling process, components such as frames, sandpaper, and liquid discharge components are collected in categories. After cleaning and testing, reusable components (such as engineering plastic frames and stainless steel bolts) are reprocessed to achieve material recycling. Consumable components (such as sandpaper and seals) are disposed of or recycled in compliance with regulations, ensuring that the entire recycling process meets environmental protection requirements, effectively reducing resource consumption and environmental pollution, and improving the sustainability of product life cycle management.

[0038] In this structure, the magnetic accumulator 2 is made of neodymium iron boron permanent magnet, and the iron plate 7 is made of low-carbon steel magnetic metal. Stable adsorption is achieved through magnetic attraction, and the adsorption force has been tested to reach 8-12 N / cm. 2 The liquid dispensing component 6 consists of a liquid dispensing tube and a micro valve. The inner diameter of the liquid dispensing tube is φ1.5-2.0mm. With the damping valve structure, the alcohol in the cavity can be controlled to flow out in a thin stream (flow rate 0.2-0.5mL / s), avoiding liquid splashing or rapid loss, and ensuring that the cleaning process is uniform and controllable. This design not only meets the liquid volume requirements for surface cleaning, but also avoids the problem of dampness at the installation interface caused by excessive liquid, thus improving the accuracy of operation.

[0039] To facilitate the operation of the iron plate 7, a handle 9 is fixedly connected to the top surface of the iron plate 7 in this embodiment. The handle 9 is made of engineering plastic and has a cylindrical structure with a grid-like textured surface to increase the contact friction between the hand and the handle, making it easier to pull. The handle 9 and the iron plate 7 are fastened together with embedded buckles and bolts to ensure a stable connection and improve the ease of operation.

[0040] To address the issue of slippage when gripping the handle 9, this embodiment adds an anti-slip layer to its outer wall. The surface of the anti-slip layer is designed with dense diamond-shaped embossed textures, with a texture depth of 1.2-1.5mm and a spacing of 4-6mm. It is integrally molded with the outer wall of the handle 9 through injection molding to form a continuous friction surface. This structure increases the actual contact area between the hand and the handle by more than 30%. Tests have shown that the gripping force can be stabilized at 15-20N in a dry environment, effectively solving the slippage problem and improving operational stability.

[0041] To improve connection stability, this embodiment adopts a double-bolt fixing structure. The two bolts are symmetrically arranged with the center of the iron plate as the reference, and the spacing is set to 60-80mm according to the frame size. The axial force of the bolts is evenly distributed through synchronous pre-tightening process, and the pre-tightening torque of a single bolt is controlled at 1.5-2.0N·m. Finite element analysis has verified that this symmetrical layout can improve the stress dispersion efficiency of the connection between the frame and the iron plate by 40%, effectively reduce the risk of off-center load, and ensure that the auxiliary component 3 maintains structural reliability during installation and disassembly.

[0042] To further enhance anti-slip performance, the anti-slip layer of the grip in this embodiment is made of nitrile rubber, which has excellent wear resistance (wear loss ≤ 150mm). 3 The surface friction coefficient (dry state ≥0.65) is tightly bonded to the outer wall of the grip through a molding process, forming a regular toothed protrusion structure (height 2.0-2.5mm, spacing 3.0-4.0mm), which can effectively increase the contact friction between the hand and the grip. According to actual tests, the grip force when wearing cotton gloves is increased to 18-22N, which is 25% better than the anti-slip effect of ordinary rubber materials, significantly reducing the risk of slipping during operation.

[0043] In order to improve the strength of the body 1, in this embodiment, the body 1 is made of thermoplastic TPU material.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
