Detailed Description
In the following description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like refer to the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not refer to or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus are not to be construed as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, 2 and 3, the high-strength quick-mounting screw comprises a screw head 1 and a screw rod 2 which are fixedly connected, wherein the screw rod 2 and the screw head 1 are both made of aluminum alloy, the strength of the aluminum alloy subjected to heat treatment strengthening and alloying strengthening can be greatly increased, and the screw made of the aluminum alloy has the property of high strength, so that the service life of the screw can be greatly prolonged.
The upper half section of the screw rod 2 is fixedly provided with threads, and the lower half section of the screw rod 2 is not provided with threads, namely the smooth rod. When a user installs a screw, the lower half section of the smooth sliding rod is firstly contacted with the installation hole, and the screw is screwed up by the screwdriver only by aligning the installation hole to be directly inserted because the section has no threads. The time for screwing and screwing the hole can be saved, and the other hand is not required to be used for pressing all the time when screwing is started, so that the time and the labor are saved.
The left end and the right end of the smooth sliding rod slide and are symmetrically provided with quick-mounting parts 3, and threads are arranged on the quick-mounting parts 3. An ejection assembly is arranged in the screw rod 2, and the ejection assembly can eject the screw rod 2 from the two quick-assembly parts 3, so that threads on the quick-assembly parts 3 are embedded with thread grooves in the mounting holes, and the overall stability of the screw in the mounting hole is ensured.
The ejection assembly comprises an ejection block 5 and a first spring 4, wherein the ejection block 5 is vertically arranged in the screw rod 2 in a sliding manner and is positioned above the quick assembly part 3. Two ends of the first spring 4 are respectively abutted against the jacking block 5 and the screw rod 2, and a guide angle is arranged at the upper end of the fast-assembling piece 3. In the normal condition, as soon as spring 4 pushes up top block 5, top block 5 and quick-fit element 3 do not interfere, and when screw 2 is mounted, quick-fit element 3 is retracted inside screw 2, so that the smooth portion of screw 2 can be inserted directly into the mounting hole. And when the kicking block 5 moves down, can support and press the lead angle of quick-mounting piece 3 upper end for quick-mounting piece 3 is outwards ejecting, makes it stretch out screw rod 2, and the screw thread on quick-mounting piece 3 imbeds in the thread groove in the mounting hole, stabilizes the screw.
A driving assembly is arranged in the screw rod 2 and comprises a pressing block 7, a driving block 6 and a second spring 8. The pressing blocks 7 horizontally slide and are symmetrically arranged on the left side and the right side of the screw rod 2, and the pressing blocks 7 are abutted with the screw head 1. The driving block 6 is fixedly arranged at the top end of the top block 5, two ends of the driving block 6 are respectively provided with an inclined plane, and two ends of the second spring 8 are respectively abutted against the two abutting blocks 7. The second spring 8 will push the pressing block 7 outwards to make it extend out of the screw 2. When the screw is installed to the end, the pressing block 7 is pressed inwards by the installation hole, and the outermost side of the pressing block is parallel to the screw rod 2. And the pressing block 7 moving inwards presses against the inclined surface of the driving block 6, so that the driving block 6 is pressed and moved downwards. The driving block 6 moving downwards drives the top block 5 to move downwards, so that the quick assembly parts 3 are finally pushed outwards, and the screws are fixed in the mounting holes.
The quick-mounting part 3 is provided with a first clamping groove 9, and two sides of the ejector block 5 are provided with second clamping grooves 10 matched with the first clamping grooves 9. When the pressing block 7 moves into the screw rod 2, the ejecting block 5 just ejects the quick-assembly part 3, and the first clamping groove 9 is in contact with the second clamping groove 10. The screw head 1 is provided with a quick-release groove 11 extending to the inside of the screw rod 2, a user can stretch into the quick-release groove 11 by using a tool and continuously press the top block 5 downwards, so that the first clamping groove 9 and the second clamping groove 10 are overlapped, the quick-assembly piece 3 can contract inwards, and time and energy during disassembly are saved.
