Description

Technical Field

[0001] This utility model relates to the technical field of hardware tool accessories, and in particular to a cavity hook opening device based on UV-resistant material. Background Technology

[0002] As is well known, existing hook-and-open devices are generally made of metal or ordinary plastic. Metal parts have defects such as UV-accelerated corrosion (measured annual corrosion rate ≥0.15mm / year) and solid plastic parts are prone to brittleness (tensile strength decreases by more than 50% after 500 hours of UV irradiation).

[0003] Most of the screwdrivers used are of a general-purpose design, and the metal handles can easily cause electric shock to the operator in humid environments. Although there are patents that attempt to improve individual components, the systemic weather resistance problem of the device and tools has not been solved. Especially in high-altitude areas with strong ultraviolet radiation, existing solutions still have structural failure and operational safety hazards. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a weather-resistant and corrosion-resistant multifunctional hook-opening tool. By optimizing materials, structure, and surface treatment technology, it significantly improves the tool's weather resistance, safety, and multifunctionality, thereby enhancing its practicality. This is a cavity-type hook-opening device based on UV-resistant materials.

[0005] This utility model discloses a cavity hook-opening device based on UV-resistant material, comprising a handle, a support block, and a hook-opening hook. The bottom end of the handle is provided with a first through-hole, and a partition plate is provided inside the first through-hole. The top inner wall of the first through-hole is provided with a first thread, and the bottom outer wall of the support block is provided with a second thread. The first thread and the second thread are threadedly connected. The top end of the support block is provided with a magnetic suction component, and the bottom end of the hook-opening hook is provided with a hexagonal block. The magnetic suction component and the hexagonal block are magnetically attached together.

[0006] Preferably, a friction sleeve is provided on the outer wall of the handle.

[0007] Preferably, the top of the hook is provided with a nail protrusion.

[0008] Preferably, it also includes a rubber sleeve, and the left and right ends of the handle are respectively provided with hanging holes, and the rubber sleeve is fitted with the two sets of hanging holes.

[0009] Preferably, the magnetic assembly includes a magnet block and a screw. The top of the support block is provided with a mounting groove, which slides and fits with the magnet block. The bottom of the mounting groove is provided with a mounting threaded hole. The top of the magnet block is provided with a hexagonal slot, and the bottom of the hexagonal slot is provided with a mounting through hole. The screw is threadedly connected to the mounting threaded hole through the mounting through hole. The hexagonal slot and the hexagonal block are magnetically fitted together.

[0010] Preferably, the first through-hole is fitted with two sets of reinforcing tubes, and the two sets of reinforcing tubes are provided with honeycomb reinforcing ribs.

[0011] Preferably, both the handle and the reinforcing plate are made of polycarbonate, and benzotriazole (such as UV-326, UV-327) or benzophenone (such as UV-531) absorbers are added during the injection molding of the handle.

[0012] Preferably, the outer layer of the friction sleeve is provided with a plasma-sprayed Al2O3 coating and impregnated with fluorosilicone resin.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses polycarbonate material with added benzotriazole (such as UV-326, UV-327) or benzophenone (such as UV-531) absorbers as the main material of the handle and reinforcing plate, which effectively improves the overall UV resistance of the tool. This not only prevents the material from becoming brittle and weakening due to long-term exposure to ultraviolet light, but also greatly extends the service life of the tool. In addition, this design uses a magnetic component to connect the support block and the hook, replacing the traditional direct fixing method, which is convenient for disassembly and increases the flexibility of use, thereby improving the tool's weather resistance, safety and multifunctionality, and thus enhancing its practicality.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] like Figures 1 to 4As shown, this utility model discloses a cavity-type hook-and-open device based on UV-resistant material, comprising a handle 1, a support block 2, and a hook 3. The bottom end of the handle 1 has a first through-hole, inside which a partition plate is disposed. The top inner wall of the first through-hole has a first thread, and the bottom outer wall of the support block 2 has a second thread. The first thread and the second thread are threadedly connected. The top end of the support block 2 has a magnetic suction component, and the bottom end of the hook 3 has a hexagonal block 4. The magnetic suction component and the hexagonal block 4 are magnetically attached. This utility model utilizes a device containing benzotriazole (such as UV-3)... Using polycarbonate materials with UV-327 or benzophenone-based absorbers (such as UV-531) as the main material for the handle and reinforcing plate effectively improves the overall UV resistance of the tool. This not only prevents material embrittlement and strength degradation caused by long-term exposure to ultraviolet light, but also greatly extends the tool's service life. Furthermore, this design uses a magnetic component to connect the support block and the hook, replacing the traditional direct fixing method. This facilitates disassembly and increases the flexibility of use, thereby improving the tool's weather resistance, safety, and versatility, and thus enhancing its practicality.

[0021] As a preferred embodiment of the above embodiment, a friction sleeve 5 is provided on the outer wall of the handle 1; the friction sleeve can effectively enhance the comfort of the handle and the friction against the hand, thereby enhancing practicality.

[0022] As a preferred embodiment of the above, the top of the hook 3 is provided with a nail protrusion; the nail can be easily lifted through the nail protrusion, increasing the practicality of the device and thus enhancing its usability.

[0023] As a preferred embodiment of the above, it also includes a rubber sleeve 6. The left and right ends of the handle 1 are respectively provided with mounting holes, and the rubber sleeve 6 is fitted with the two sets of mounting holes. The equipment can be conveniently mounted through the two sets of mounting holes, and the rubber sleeve protects and stabilizes the two sets of mounting holes, thereby enhancing practicality.

[0024] As a preferred embodiment of the above, the magnetic assembly includes a magnet block 7 and a screw 8. The top of the support block 2 is provided with a mounting groove, which is slidably fitted with the magnet block 7. The bottom of the mounting groove is provided with a mounting threaded hole. The top of the magnet block 7 is provided with a hexagonal slot, and the bottom of the hexagonal slot is provided with a mounting through hole. The screw 8 is threadedly connected to the mounting threaded hole through the mounting through hole. The hexagonal slot and the hexagonal block 4 are magnetically fitted together. The magnet block is installed by the screw, and different tools can be easily replaced by the magnet block. It can also attach magnetism to the tools, thereby enhancing practicality.

[0025] As a preferred embodiment of the above, the first through-hole is fitted with two sets of reinforcing tubes 9, and the two sets of reinforcing tubes 9 are provided with honeycomb reinforcing ribs; the design of the reinforcing tubes including honeycomb reinforcing ribs makes the whole device lighter while having stronger structural strength, effectively resisting damage to the tool caused by the external environment, especially when used in high-altitude areas with strong ultraviolet radiation, thus enhancing its practicality.

[0026] As a preferred embodiment of the above embodiment, both the handle 1 and the reinforcing plate are made of polycarbonate. When the handle 1 is injection molded, benzotriazole (such as UV-326, UV-327) or benzophenone (such as UV-531) absorbers are added. This invention, by adding benzotriazole (such as UV-326, UV-327) or benzophenone (such as UV-531) absorbers during the injection molding process of the polycarbonate handle, can effectively absorb ultraviolet rays and reduce the aging effect of ultraviolet rays on the material. This not only extends the service life of the handle but also maintains the stability of its physical properties, thereby enhancing its practicality.

[0027] As a preferred embodiment of the above embodiment, the outer layer of the friction sleeve 5 is provided with a plasma-sprayed Al2O3 coating and impregnated with fluorosilicone resin. Due to its high hardness, the plasma-sprayed Al2O3 coating on the outer layer of the friction sleeve greatly improves the wear resistance of the friction sleeve and reduces wear during daily use. After being impregnated with fluorosilicone resin, the friction sleeve has better waterproof, oil-proof and chemical corrosion resistance. This means that even in harsh working environments, the friction sleeve can maintain good performance and is not easily affected by external substances, thereby enhancing its practicality.

[0028] This utility model discloses a cavity-type hook-opening device based on UV-resistant material. Its working principle is as follows: First, during assembly, the top reinforcing tube is inserted into the first through-hole, followed by the installation of a rubber sleeve. Then, the bottom reinforcing tube is inserted into the first through-hole. Next, the handle is threadedly connected via the second thread on the support block. Then, a suitable hook is selected and inserted with a magnet block. Finally, the friction sleeve is fitted onto the handle. During use, due to the arc-shaped top of the hook and the nail-shaped protrusion at the top, the cavity can be pried open using leverage. It can also be used to quickly pry up nails using leverage. After use, the handle is hung on the wall through the hole in the middle of the rubber sleeve.
