The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
Example 1
As shown in figure 1, the special tool for disassembling the lock head and the nut of the lifting appliance comprises a locking block 1, a tool head 2 and a push rod 3. Wherein the locking block 1 is movably connected with the tool head 2, and the push rod 3 is fixedly connected with the tool head 2.
As shown in fig. 2, the tool bit 2 includes a socket portion 21, a mounting hole 22, and a connecting portion 23.
As shown in fig. 3, a nut 4 is provided on the top of the lock head 5 of the lifting appliance, and a tooth mouth 41 is provided around the top of the nut 4.
The sleeve head portion 21 is in a hollow disc shape, and the inner diameter of the sleeve head portion is matched with the outer diameter of the screw cap 4, so that the sleeve head portion 21 can be tightly matched with the screw cap 4 and is not easy to fall off during rotation. Six mounting holes 22 are uniformly distributed on the circumference of the sleeve head part 21, a connecting part 23 is fixed between two mounting holes 22, and the connecting part 23 can be fixed with the sleeve head part 21 by welding or can be integrally formed with the sleeve head part 21.
As for the mounting hole 22, it is used in cooperation with the locking block 1, so that the cross-sectional area of the mounting hole 22 is larger than that of the locking block 1. In this embodiment, the cross-sectional shapes of the mounting hole 22 and the locking block 1 are both rectangular, but in other embodiments, the cross-sectional shapes of both may be circular or polygonal. In the use process, the mounting hole 22 needs to correspond to the position of the tooth mouth 41, so that the locking block 1 is conveniently limited in the tooth mouth 41, the tool head 2 can drive the screw cap 4 to rotate, and the reliable transmission of the rotating force acting on the screw cap 4 is ensured; the number of the mounting holes 22 is not less than the number of the mouthpiece 41.
For the locking block 1, the locking block is movably connected with the sleeve head part 21; the number of locking blocks 1 in this embodiment is also six, as are the number of mounting holes 22. Since the locking block 1 needs to pass through the mounting hole 22 during use, the shape of the locking block 1 is consistent with the shape of the mounting hole 22 and is slightly smaller than the mounting hole 22. The design facilitates the self installation and disassembly process of the special nut disassembly tool
As for the connecting portion 23, it is used for fixedly mounting the push rod 3; the connecting part 23 is provided with a limiting groove 231, and the push rod 3 is inserted into the limiting groove 231; since the stopper groove 231 has a certain depth, the tool can be rotated by directly inserting the push rod 3 into the stopper groove 231 when in use. In some embodiments, the limiting groove 231 is threaded, and the end of the push rod 3 is threaded in a direction matching the limiting groove 231, so that the push rod 3 can be screwed into the limiting groove 231 for fixing.
In some embodiments, the push rod 3 is an extension rod, where the length of the push rod 3 is 3-4 times the outer diameter of the cuff head 21. The force arm of the push rod 3 is greatly increased, the left and right operation is convenient, the labor is saved, and the disassembly and the installation are convenient.
The working principle of the embodiment is as follows:
in the use process, the sleeve head part 21 is sleeved outside the screw cap 4; the mounting hole 22 is then aligned with the mouth 41 of the nut 4; according to the number of the tooth mouths 41, each locking block 1 is limited at the tooth mouth 41 of the nut 4 through the mounting hole 22; if the number of the tooth mouths 41 is smaller than that of the mounting holes 22, the locking blocks 1 are inserted into the mounting holes 22 at equal intervals as far as possible; and finally, the push rod 3 is fixed on the connecting part 23 of the tool head 2, and after the push rod 3 is pushed, each locking block 1 applies a rotating force to the nut 4 through the tooth mouth 41 of the nut 4, so that the nut on the lock head of the lifting appliance is quickly disassembled.
The shape matching of the sleeve head 21 and the nut 4 in this embodiment is to prevent the sleeve head from falling off easily during rotation; meanwhile, according to the characteristic that the screw cap 4 is provided with the tooth mouth 41, the locking blocks 1 with the same number are inserted into the mounting hole 22 at equal intervals, so that the tool head 2 and the screw cap 4 are completely fixed; both realized on the hoist tapered end quick safe dismantlement of nut 4, should dismantle specialized tool also can be fast convenient install on nut 4 or demolish from nut 4 simultaneously.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
