[0035] The following will be described in detail below with reference to the accompanying drawings Figures 1-8 The present application will be further described in detail.

[0036] The embodiment of the present application discloses a fastening structure of a stable variable integrated machine.

[0037] Reference Figures 1-5 , Figure 8 The fastening structure of the stable variable integrated machine comprises a base 31 for mounting the transformer body 3 on the top of the supporting plate 2 inside the case 1, and a fastening assembly 4 for fixedly mounting the base 31 on the top of the supporting plate 2, which is arranged on the base 31 and the supporting plate 2.

[0038] The fastening assembly 4 comprises an active column 42 penetrating through the side wall of the base 31, the surface of the active column 42 is fixedly connected with a threaded one 43, the top of the base 31 is provided with a threaded groove 413 matched with the shape of the active column 42 and the threaded one 43, the active column 42 is threadedly connected in the threaded groove 413, a hexagonal cap 41 is fixedly connected on the top of the active column 42, the top center of the hexagonal cap 41 and the top center of the active column 42 are both provided with a through hole 414 matched with the shape of the insertion rod 44, the insertion rod 44 is movably inserted in the through hole 414, and the top end and the bottom end of the insertion rod 44 extend to the outside through the through hole 414, a sliding block 411 is fixedly sleeved on the surface of the insertion rod 44, a sliding groove one 412 matched with the shape of the insertion rod 44 is arranged in the inner center of the insertion rod 44 and the hexagonal cap 41, and the sliding block 411 is slidingly installed in the sliding groove one 412.

[0039] A plurality of active columns 42 on the base 31 are aligned with a plurality of cavities 420 on the top of the supporting plate 2, then the active columns 42 are inserted in the cavities 420, so that the bottom of the base 31 is attached to the top of the supporting plate 2.

[0040] A cavity 420, which matches the shape of the movable column 42, is opened on the top of the support plate 2. A mounting plate 45 is fixedly embedded in the bottom of the cavity 420. A bifurcated elastic spindle 46 is fixedly installed in the center of the top of the mounting plate 45. The bifurcated elastic spindle 46 can be divided into several blades. Several conical blocks 47 are fixedly installed on the top of several blades. A conical groove 48, which matches the shape of several conical blocks 47, is opened in the center of the bottom of the movable column 42. The conical groove 48 communicates with the through hole 414. A second mounting slot 419, which matches the shape of the mounting rod 44, is opened in the center of the bottom of the bifurcated elastic spindle 46 and the mounting plate 45. A first slot 49, which matches the shape of the mounting rod 44, is opened in the center of the bottom of the cavity of several cavities 420. A gasket 410 is fixedly installed in the bottom of the cavity of the first slot 49. The gasket 410 is made of rubber. The mounting rod 44 is inserted into the inside of the second slot 419.

[0041] The movable column 42 is inserted into the cavity 420. After the bottom of the base 31 is attached to the top of the support plate 2, the insertion rod 44 is pushed. The insertion rod 44 passes through the forked elastic spindle 46 and the slot 419 on the mounting plate 45 and extends into the slot 49. The bottom end of the insertion rod 44 abuts against the top of the gasket 410. Then, the movable column 42 is rotated clockwise by the cooperation of the hex wrench and the hex cap 41. Because the thread 43 fixed on the surface of the movable column 42 cooperates with the thread groove 413, the movable column 42 moves downward while rotating. The tapered groove 48 at the bottom of the movable column 42 is designed to match the tapered block 47 on each blade of the forked elastic spindle 46. When the movable column 42 moves downward, the taper of the tapered groove 48... As the taper of the conical groove 48 gradually increases, the contact area with the conical blocks 47 also gradually increases. Due to the increased taper of the conical groove 48, it exerts an inward squeezing effect on the conical blocks 47. This squeezing effect causes the bifurcated plates of the bifurcated elastic spindle 46 to be subjected to a force that converges towards the center. When the movable column 42 moves down to the bottom of the inner cavity of the slide groove 412, the bifurcated elastic spindle 46 is just distributed into a cylindrical structure. The bifurcated elastic spindle 46 is tightened as a whole, and the bifurcated elastic spindle 46 clamps and fixes the insertion rod 44. Because the movable column 42 cannot be pulled out from the cavity 420 under the limit of the slide 411, the base 31 is fixed on the top of the support plate 2. The operation is simple and convenient, and the stability is high.

[0042] Reference Figure 6 , Figure 7 The locking block 415 is fixed to the surface of the insertion rod 44. The second sliding groove 416, which is adapted to the shape of the locking block 415, is opened on the inner surface of the bifurcated elastic spindle 46. The third sliding groove 417, which is adapted to the shape of the locking block 415, is opened on the inner surface of the mounting plate 45. The rotating groove 418, which is adapted to the shape of the locking block 415, is opened on the inner surface of the mounting plate 45 and communicates with the third sliding groove 417. The rotating groove 418 only allows the locking block 415 to rotate 90°.

[0043] When the insertion rod 44 is inserted into the slot one 49, the clamping block 415 will pass through the sliding groove two 416 and be inserted into the bottom of the sliding groove three 417, then rotate the insertion rod 44 clockwise by 90 degrees, and rotate the clamping block 415 into the rotating groove 418, at this time, under the action of the clamping block 415, the insertion rod 44 cannot slide up and down in the slot one 49, avoiding the sliding of the insertion rod 44 when the movable column 42 is screwed.

[0044] The implementation principle of the fastening structure of the stable variable all-in-one machine is as follows: place the base 31 on the top of the supporting plate 2, align the movable column 42 on the base 31 with the cavity 420 on the top of the supporting plate 2, so that the movable column 42 is inserted into the cavity 420, then push the insertion rod 44, insert the insertion rod 44 into the slot one 49, and at the same time, the clamping block 415 will pass through the sliding groove two 416 and be inserted into the bottom of the sliding groove three 417, then rotate the insertion rod 44 clockwise by 90 degrees, and rotate the clamping block 415 into the rotating groove 418, at this time, under the action of the clamping block 415, the insertion rod 44 cannot slide up and down in the slot one 49;

[0045] Then drive the movable column 42 to rotate by cooperating the hexagonal wrench with the hexagonal cap 41, because the thread one 43 on the surface of the movable column 42 is matched with the thread groove 413, the movable column 42 continuously moves downward while rotating, and the taper groove 48 at the bottom of the movable column 42 is designed to be matched with the tapered block 47 on each blade of the bifurcated elastic mandrel 46, when the movable column 42 moves downward, the taper of the taper groove 48 gradually increases, and the contact area with the tapered blocks 47 also gradually increases, because the taper of the taper groove 48 increases, it will produce an inward extrusion effect on the tapered blocks 47, this extrusion effect will make the bifurcated blades of the bifurcated elastic mandrel 46 receive a force of gathering to the center, causing the bifurcated elastic mandrel 46 to tighten as a whole, the bifurcated elastic mandrel 46 clamps and fixes the insertion rod 44, and then fixes the base 31 on the top of the supporting plate 2, which is simple and convenient to operate and has high stability.

[0046] When the transformer body 3 needs to be disassembled, the movable column 42 is driven to rotate counterclockwise by the hexagonal wrench, so that the movable column 42 continuously moves upward while rotating, when the movable column 42 moves upward to the position where the sliding block 411 slides to the top of the sliding groove one 412, the extrusion force acting on the tapered blocks 47 disappears, the bifurcated elastic mandrel 46 returns to the original position, and then the bifurcated elastic mandrel 46 no longer clamps and fixes the insertion rod 44, and then the movable column 42 can be pulled out of the cavity 420, so that the base 31 can be disassembled from the top of the supporting plate 2.

[0047] The above is only an optional embodiment of the present disclosure, and is not used to limit the present disclosure. Those skilled in the art can make various changes and modifications to the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
