Wherein FIG. 7 is also taken as an abstract figure
The invention provides a novel expansion bolt convenient to disassemble, which overcomes the defects of the prior art, is mainly used for installing hollow pipe walls of steel structures, aluminum alloy structures, stainless steel and the like, and is particularly suitable for installing square pipes, angle steel, H-shaped steel, channel steel and special composite plates. (see fig. 6), the above-described taper nuts may each have a taper and a rounded curve transition.
The novel expansion bolt convenient to disassemble consists of an expansion nut, an expansion pipe, a spring gasket and a screw (shown in figure 7).
The expansion nut is composed of a cone nut and a boss, and is characterized in that: the cone nut is provided with a plurality of bosses, the tail of the cone nut is provided with a chamfer or a fillet, and the cone nut is various in shape. The taper nut with the taper and the boss form an expansion nut (1) (as shown in figure 1), and the taper nut with the smooth curved surface transition and the boss form an expansion nut (2) (as shown in figure 2). (Note: the above-mentioned "plurality" means two or more)
The expansion pipe is composed of an expansion sheet and a sleeve (as shown in figure 4), or the expansion sheet, the sleeve and a gasket can be integrally connected or detachably combined and connected to form the expansion pipe (1) (as shown in figure 3) or the expansion pipe (3) (as shown in figure 5). The split-combined connection can be connected by the following methods (for example, welding, inserting, riveting, rolling, threading, expansion and other processes can be used). If the sleeve, the expansion sheet and the gasket are fixedly connected in a detachable and combined manner (for example, the processes of welding, riveting, stamping, threading, expanding and the like can be used). If the sleeve and the expansion sheet are integrally connected, but the sleeve and the check ring are movably connected in a combined manner (such as inserting, rolling, blocking and the like), the sleeve is not easily pulled, and the disassembly is not easily performed, but the invention is not substantially influenced, and the hexagonal check ring has the same function and function as the common check ring (or the gasket) and also has the function of blocking the rotation of the sleeve.
The specific implementation mode is as follows:
as shown in the figure: only three connection methods are listed, and a plurality of combination connection methods are not listed.
The connection method 1: comprises an expansion nut (2), an expansion pipe (2), a gasket, a spring gasket and a screw rod.
The connection method 2: comprises an expansion nut (1), an expansion pipe (1), a spring gasket and a screw rod.
The connection method 3: comprises an expansion nut (1), an expansion pipe (3), a spring gasket and a screw (as shown in figure 7).
Taking the connection method 3 as an example only: as shown in fig. 7, and is embodied in conjunction with the installation schematic (fig. 6).
The cone nut (1) is integrally connected with the boss (2), and the sleeve (5), the expansion sheet (4) and the gasket (6) are movably connected in a split combination way (for example, the process methods such as insert and the like can be used). The taper of the conical nut (1) is basically the same as or different from that of the expansion sheet (4), and the expansion sheet (4) can be provided with round corners or chamfers and can also be embossed or protruded. Firstly, a clamping table (10) on the gasket (6) is inserted into a clamping groove (9) on the sleeve (5).
The guiding function is as follows:
4 equipartitions in this design just insert 4 equipartitions and have tapering inflation piece (4) and have in 4 equipartitions and have tapering boss (2), boss (2) and inflation piece (4) belong to clearance fit, and the top edge that the topside of boss (2) is higher than inflation piece (4) keeps flat, blocks inflation piece (4). The expansion nut (1) and the expansion pipe (3) are coaxially guided, and do linear reciprocating motion along the opening of the expansion sheet (4). If the expansion pipe (3) does not rotate, the expansion nut (1) cannot rotate, and can only do linear reciprocating motion along the expansion sheet (4) but cannot rotate, except the guide range beyond the expansion sheet (4).
Pre-pressing and fixing:
make corresponding hole to component side pipe (14), component composite sheet (15) earlier, adjusted and dismantled convenient novel expansion bolts, put into the component hole to it, put the platform of packing ring (6) with the opening of spanner on, hold the spanner motionless with the left hand, during right hand sleeve pipe spanner inserted hexagon flange screw rod (3), with certain power pre-compaction sleeve pipe spanner of right hand, locking hexagon flange screw rod (3), realized the installation of pre-compaction fixed component.
Internal rotation locking:
after the component and the expansion bolt are pre-pressed and fixed, the right hand is screwed into a sleeve spanner on the rotary hexagonal flange screw (3), and the expansion nut (1) does not rotate because the expansion pipe (3) does not rotate. Namely a hexagonal flange screw (3). The hexagonal flange screw (3) is supposed to rotate reversely relative to the expansion nut (1) without rotating. And because the expansion nut (1) is arranged in the component, the expansion nut is locked by internal rotation.
The strength is large:
the expansion nut (1) and the expansion pipe (3) are high in matching precision, the machining process is not complex, and due to the fact that the boss (2) in the expansion nut (1) is provided with the taper and the tail portion is provided with the round angle or the chamfer angle. The main functions of the taper and the chamfer are to lock or insert the components (14) and (15) in holes conveniently and smoothly and ensure the matching coaxiality of the components (14) and (15) in the holes. But also can increase the length of the screw thread of the expansion nut (1), increase the stress intensity and protect the nut. Therefore, the strength is high.
Can be conveniently disassembled:
after the installation is finished, the novel expansion bolt is required to be disassembled.
And the hexagonal flange screw (3) can be screwed in and out. After the hexagonal flange screw rod (3) is screwed out for a certain distance, the gasket (6) on the sleeve is pried by a straight screwdriver, the hexagonal platform on the gasket (6) is clamped by a spanner, the hexagonal flange screw rod (3) is screwed out gradually, and the gasket (6) and the sleeve (5) are in clearance fit with the clamping table (10) through the clamping groove (9), so that the gasket (6) can be pulled out, and the component (15) can be moved out.
The method comprises the following steps: after the component (15) is moved out, the expansion nut (1) is propped against the hexagonal flange screw (3) to enable the expansion nut (1) to be separated from the expansion sheet (4) and fall into the component (14), then the sleeve (5) is pulled out by force through a pliers, under the action of pulling force, the hole of the component (14) blocks the expansion sheet (4), the expansion sheet (4) is enabled to deform, contract and reset, and the sleeve (5) is pulled out.
The method 2 comprises the following steps: after the component (15) is removed, the sleeve (5) is slightly hammered inwards by a hammer, so that the sleeve (5) and the expansion nut (1) fall into the component (14), and the disassembly can be completed by repeating the above operation processes for several times.
This completes the embodiment.
Because the expansion bolt is easy to disassemble, the expansion bolt is a novel expansion bolt convenient to disassemble.
It should be understood that the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
