Detailed Description

In order to enable those skilled in the art to better understand the technical scheme of the present utility model, the following detailed description is provided with reference to the accompanying drawings:

Referring to fig. 2 to 5C, an improved multifunctional round nut replacer according to a preferred embodiment of the present utility model includes a main fixing bracket 1, an auxiliary fixing bracket 2, and four disassembly legs 3.

Referring to fig. 3A and 3B, the main fixing bracket 1 has a cross structure, four sides of the main fixing bracket 1 form four main guide rails 11, and each main guide rail 11 is provided with a strip guide groove 12 penetrating from front to back; the front side of the main fixing support 1 is provided with a cross baffle 14, the cross crossing position of the main fixing support 1 is connected with the cross crossing position of the baffle 14 through a connecting column 15, and the front side of the cross crossing position of the baffle 14 is provided with a hexagon head 13.

The strip-shaped guide groove 12 of the main fixing support 1 is used for installing the dismounting legs 3, the width L1 of the strip-shaped guide groove 12 is matched with the width dimension of the dismounting legs 3, the dismounting legs 3 can freely slide in the strip-shaped guide groove 12, and the distance between the dismounting legs 3 is used for adjusting, so that round nuts with different specifications can be dismounted. During operation, the hexagonal head 13 is clamped by a wrench, the whole structure is driven to rotate, and the round nut is disassembled and assembled. The main guide rail 11 should have a certain thickness H1 and a certain width L2, since here it is necessary to have a certain strength not only for guiding but also for transmitting torque during operation.

Referring to fig. 4A and fig. 4B, the auxiliary fixing support 2 has a cross structure, four sides of the auxiliary fixing support 2 form four auxiliary guide rails 21, and each auxiliary guide rail 21 is provided with a strip-shaped guide groove 22 penetrating from front to back; the elongated guide groove 22 of the sub-fixing bracket 2 is used for assisting in fixing the attaching/detaching leg 3. The width L1 'of the elongated guide groove 22 is identical to the width L1 of the elongated guide groove 12, the thickness H2 and the width L2 of the sub guide rail 21 may be slightly smaller than the thickness H1 and the width L2' of the main guide rail 11, and the sub fixing bracket 2 does not need a hexagonal head structure.

The main fixing bracket 1 and the auxiliary fixing bracket 2 are arranged in tandem and opposite to each other.

Referring again to fig. 5A, 5B and 5C, each of the dismounting legs 3 includes a top cover 31, a rod body 32 and a cylindrical dismounting leg 33 connected in sequence, and the cylindrical dismounting leg 33 of the dismounting leg 3 is generally a cylindrical structure with a diameter d1 (see fig. 5A).

One end of the rod body 32 is connected with the top cover 31; the other end is provided with a threaded hole 34 with the aperture of M1, one end of the cylindrical dismounting foot 33 is a threaded head with the outer diameter of M1, and the threaded head is detachably connected in the threaded hole 34 in a threaded mode. A plurality of cylindrical dismounting legs 33 of different diameters d2 are machined for replacement adjustment according to specifications of different round nuts (see fig. 5C).

The rod bodies 32 of the four dismounting legs 3 penetrate through the strip-shaped guide grooves on the four main guide rails 11 and the four auxiliary guide rails 21 in a one-to-one correspondence manner, and the top covers 31 of the four dismounting legs 2 are respectively positioned between the main fixing support 1 and the baffle 14. The baffle 14 is used for preventing the axial movement of the dismounting leg 3, so that the dismounting leg 3 is more convenient to use, and the gap H4 between the baffle 14 and the main fixing bracket 1 is slightly larger than the thickness H3 of the top cover 31 of the dismounting leg 3.

The rod body 32 of the detachable leg 3 has a generally rectangular structure, and the cross section of the rod body 32 has a rectangular shape with a width of L4 x a height of L5, so as to facilitate better torque transmission. The width L4 of the rod body 32 of the detachable leg 3 should be slightly smaller than the width L1 of the elongated guide groove. If the width L4 of the rod body 32 is too small, the dismounting legs 3 are too loose after being mounted, so that the use is inconvenient; if the width L4 of the rod body 32 is too large, it is difficult to install and adjust. The height L5 of the mounting leg may be equal to or less than the width L4, but is not so small as to be strong. The top cover 31 of the mounting leg may take the shape of a circle of diameter L6 or a rectangle of width L6, L6 being approximately equal to the width L2 of the main guide rail 11. The length L7 of the rod body 32 of the mounting leg 3 can be designed and processed according to the actual detachable work piece.

The utility model relates to an improved multifunctional round nut replacer, which is characterized in that the round nut is usually provided with 4 disassembly and assembly grooves when four guide rails are designed. During operation, because the length L7 of the dismounting leg 3 is long enough, the cylindrical dismounting leg 33 of the mounting leg 3 can be directly inserted into the round nut with relatively deep mounting position to be dismounted, then the hexagonal head 13 of the main fixing support 1 is clamped by a wrench, the mounting leg 3 is driven to rotate, and then the round nut is driven to rotate, so that all parts except the round nut are not required to be dismounted, enough dismounting space is reserved for the round nut, and the operation is simpler.

Referring to fig. 6, when the round nut has a larger size and the torque transmission of the dismounting device is difficult, a pry bar 4 can be arranged between the main fixing bracket 1 and the auxiliary fixing bracket 2 for auxiliary dismounting, and the pry bar 4 is obliquely inserted into a cubic frame formed by the main fixing bracket 1, the auxiliary fixing bracket 2 and the four dismounting legs 3.

According to the improved multifunctional round nut replacer disclosed by the utility model, the positions of the mounting legs 3 in the corresponding strip-shaped guide grooves can be adjusted so as to meet the disassembly and assembly requirements of round nuts with different specifications. The mounting legs can meet the requirements of the disassembly of round nuts with different depth structures by processing rod bodies 32 with different lengths L7, and the mounting device is convenient to use and high in applicability.

In summary, the improved multifunctional round nut replacer disclosed by the utility model has the advantages that the cylindrical disassembly and assembly legs of the disassembly and assembly legs can be disassembled and replaced, so that the disassembly and assembly legs with different sizes are convenient to replace and adjust, the disassembly and assembly legs are suitable for disassembly and assembly of round nuts with different sizes, the baffle plate is additionally arranged, the axial movement of the disassembly and assembly legs can be prevented, the assembly and disassembly of the shaft extension round nuts can be more conveniently assisted, and the disassembly and assembly device is particularly suitable for disassembly and assembly of round nuts with relatively deep installation positions.

It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
