[0027] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The fastener shown is used for high-pressure cast aluminum elevated floors, including a bottom column 1 and a high-pressure cast aluminum elevated floor body 2. The lower end of the bottom column 1 is welded with a bottom mounting seat 3 fixed to the bottom surface with bolts. A longitudinal adjustment tube 4 is movably assembled inside the bottom column 1. A top support plate 5 is axially fixed to the top end of the longitudinal adjustment tube 4. Four flip-type locking arms 6 are movably mounted on the lower end of the top support plate 5 through lateral brackets.

[0030] Installation principle: people first measure and fix the bottom mounting base 3 to the ground with the bottom bolts, then lift the longitudinal adjustment tube 4 and the top support plate 5 to the specified height as required, and then place the high-pressure cast aluminum elevated floor body 2 on the upper end of the top support plate 5. Then, by controlling the flip-type locking arm 6, flip and extrude the inner wall of the high-pressure cast aluminum elevated floor body 2, so that the adjacent high-pressure cast aluminum elevated floor bodies 2 are squeezed, fitted and fixed to complete the installation. The advantage of this is that no openings and fasteners are left at the upper end, which improves durability.

[0031] In order to control the bottom end and facilitate height adjustment, an internal control screw 7 for controlling the longitudinal adjustment tube 4 is longitudinally assembled inside the bottom column 1. The bottom end of the internal control screw 7 has a first conical tooth head 71 with an integrated structure. The upper end of the internal control screw 7 is inserted into the interior of the longitudinal adjustment tube 4 and threadedly engaged with the internal threaded surface of the longitudinal adjustment tube 4.

[0032] People use an external tool, that is, an adjustment rod with a conical tooth head at the top to control the engagement and rotation of the first conical tooth head 71 at the lower end of the internal control screw 7, and then drive the longitudinal adjustment tube 4 to rise and fall at the opening position at the upper end of the bottom column 1 by rotating the internal control screw 7.

[0033] The upper end of the internal control screw rod 7 is inserted into the interior of the longitudinal adjustment tube 4 and is threadedly engaged with the internal screw hole in the longitudinal adjustment tube 4 .

[0034] In order to cooperate with the bottom control, the inner top surface of the longitudinal adjustment tube 4 is movably equipped with an inner top adjustment worm 8 for controlling the flip locking arm 6, and the bottom end of the inner top adjustment worm 8 has an integral second conical tooth head 81.

[0035] In order to cooperate with the flipping and extrusion limiting, the flipping locking arm 6 includes an arc-shaped flipping arm 61 axially mounted on a lateral bracket, a split extrusion limiting head 62 axially fixed on the extrusion end of the arc-shaped flipping arm 61, and an integrated control worm gear 63 fixed on the side wall of the flipping end of the arc-shaped flipping arm 61.

[0036] The arc-shaped flip arm 61 flips upward, driving the split extrusion limit head 62 to be inserted into the inner wall of the inner angle of the lower opening of the high-pressure cast aluminum elevated floor body 2, thereby flipping and extruding the high-pressure cast aluminum elevated floor body 2 to limit the position.

[0037] In order to cooperate with the assembly transmission, the outer side of the longitudinal adjustment tube 4 corresponds to the lateral transmission opening 41 that cooperates with the control worm gear 63.

[0038] The control worm wheel 63 passes through the lateral transmission opening 41 and meshes with the outer side of the inner top type adjusting worm 8.

[0039] In order to facilitate lateral control, lateral control through holes 100 are opened on the side wall of the bottom column 1 corresponding to the first conical tooth head 71 and on the side wall of the longitudinal adjustment tube 4 corresponding to the second conical tooth head 81.

[0040] In order to cooperate with installation and limiting, an end assembly socket 611 for installing a split extrusion limit head 62 is provided at the extrusion end of the arc-shaped flip arm 61, and a lateral adjustment screw hole connected to the interior of the end assembly socket 611 is provided on the outer surface of the arc-shaped flip arm 61. A lateral locking bolt 612 is inserted into the internal thread of the lateral adjustment screw hole, and an internal extrusion spring 614 is installed on the inner wall of the end assembly socket 611 through an inner assembly shaft 613.

[0041] An extrusion blind hole matching the inner assembly shaft 613 and the internal extrusion spring 614 is provided at the plug-in end of the split extrusion limit head 62 . The internal extrusion spring 614 is inserted into the extrusion blind hole to come into extrusion contact with the split extrusion limit head 62 .

[0042] Then people use an external tool, such as a screwdriver with a conical tooth head on the top, to insert it to engage with the second conical tooth head 81, and then rotate to control the rotation of the second conical tooth head 81, and then drive the inner top adjustment worm 8 to rotate. The inner top adjustment worm 8 adjusts the angle of the worm wheel 63 by rotating, thereby rotating the arc-shaped flip arm 61. The arc-shaped flip arm 61 then drives the split extrusion limit head 62 to flip and extrude the inner angle of the high-pressure cast aluminum elevated floor body 2, thereby controlling the adjacent high-pressure cast aluminum elevated floor bodies to be clamped and limited, completing the assembly.

[0043] In order to cooperate with lateral limiting and guiding, a strip-shaped limiting groove 621 that cooperates with the lateral locking bolt 612 is opened on the outer side surface of the split extrusion limiting head 62.

[0044] The lateral locking bolt 612 is inserted into the strip-shaped limiting groove 621 by rotating toward the inside of the lateral adjustment screw hole. At this time, the split extrusion limiting head 62 can be restricted from being separated from the end assembly socket 611, while also ensuring a certain degree of elastic shock-absorbing stroke.

[0045] In order to cooperate with the outer sealing and limiting, thereby ensuring the limiting ability of the first conical tooth head 71 or the second conical tooth head 81, a lateral limiting slot 101 is opened at the outer opening position of the lateral control through hole 100, and an elastic limiting plug 9 is inserted into the lateral limiting slot 101.

[0046] The first elastic limiting plug 901 is inserted into the lateral limiting slot corresponding to the position of the first conical tooth head 71 on the side wall of the bottom column 1, and the second elastic limiting plug 902 is inserted into the lateral limiting slot corresponding to the position of the second conical tooth head 81 on the longitudinal adjustment tube 4.

[0047] In order to improve the limiting ability in daily use, the first elastic limiting plug 901 and the second elastic limiting plug 902 both include an internal limiting plate 91, an internal guide tube 92 of an integrated structure fixed on the side wall of the internal limiting plate 91, an internal limiting tooth head 93 elastically inserted into the internal guide tube 92, and a rubber fastening frame 94 mounted on the outer surface of the internal limiting plate 91.

[0048] The internal limiting plate 91 is inserted into the lateral limiting slot 101 through the outer rubber fastening frame 94 , and then the rubber fastening frame 94 is installed and limited by the limiting blocks on the outer surface of the lateral limiting slot 101 .

[0049] By inserting the internal guide tube 92 into the lateral control hole and then using the internal limit tooth head 93 to engage with the first conical tooth head 71 or the second conical tooth head 81, the first conical tooth head 71 or the second conical tooth head 81 is locked, providing the purpose of secondary locking.

[0050] The internal limiting tooth head 93 provides sufficient extrusion force through the limiting spring inside the internal guide tube 92.

[0051] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
