DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] An embodiment of an installation assembly for a wall bushing for electric power construction of the present invention is as follows: Figures 1 to 6 shown.

[0026] A mounting assembly for a wall bushing for power construction is used to horizontally mount the wall bushing 100 on a wall 200, on which a reserved hole 210 is provided, and comprises a mounting plate 300, an adjusting plate 400 and a plurality of adjusting assemblies 500. The mounting plate 300 and the adjusting plate 400 are sequentially arranged on the wall bushing 100 along a first direction and are both coaxial with the wall bushing 100, wherein the first direction is the axial direction of the wall bushing 100. The radius of the mounting plate 300 is greater than the radius of the reserved hole 210. The radius of the adjusting plate 400 is less than the radius of the reserved hole 210, so that the adjusting plate 400 can pass through the wall 200. The two side surfaces of the wall 200 in the first direction are respectively referred to as the first side surface and the second side surface. The mounting plate 300 and the adjusting plate 400 are respectively located on both sides of the wall 200 in the first direction. The mounting plate 300 can abut against the first side surface.

[0027] A plurality of adjustment components 500 are evenly distributed on the adjustment disk 400 around a first direction, and the adjustment component 500 includes an adjustment block 510 and two limit blocks 520, the two limit blocks 520 are respectively located on both sides of the adjustment block 510 around the first direction, and in an initial state, a gap is left between the adjustment block 510 and the two limit blocks 520. The opposing surfaces of the adjustment block 510 and the two limit blocks 520 around the first direction are friction surfaces, and the adjustment block 510 and the two limit blocks 520 can slide on the adjustment disk 400 along a second direction, and the second direction is a radial direction of the wall bushing 100.

[0028] The adjustment component 500 has a first state and a second state. When in the first state, the adjustment block 510 does not abut against the second side surface, and the adjustment block 510 and the two limit blocks 520 move synchronously in the second direction; when in the second state, the adjustment block 510 abuts against the second side surface, and the adjustment block 510 moves in the second direction relative to the two limit blocks 520, and the movement of the adjustment block 510 in the second direction relative to the two limit blocks 520 can make the adjustment block 510 abut against the two limit blocks 520.

[0029] Furthermore, end surfaces of the adjusting block 510 and the two limiting blocks 520 close to one end of the second side surface in the first direction are both friction surfaces.

[0030] In this embodiment, by providing a mounting plate 300, an adjusting plate 400 and a plurality of adjusting components 500, when the wall sleeve 100 is installed on the wall 200, since the radius of the adjusting plate 400 is smaller than the radius of the reserved hole 210, the adjusting plate 400 can pass through the wall 200 and be located on the same side as the second side of the wall 200, that is, the adjusting plate 400 and the mounting plate 300 are respectively located on both sides of the wall 200 in the first direction, and the mounting plate 300 is abutted against the first side of the wall 200.

[0031] The side close to the central axis of the wall sleeve 100 in the first direction along the second direction is called the inner side, and the side away from the central axis of the wall sleeve 100 in the first direction along the second direction is called the outer side. The adjustment block 510 is driven to move outward in the second direction, and the adjustment assembly 500 is in the first state at this time. When the adjustment block 510 moves outward in the second direction, the adjustment block 510 moves synchronously with the limit block 520. The adjustment block 510 and the two limit blocks 520 slide along the reserved hole 210 in the second direction, and the adjustment block 510 does not abut against the second side surface of the wall 200. When the adjustment block 510 moves to abut against the second side of the wall 200, the adjustment assembly 500 switches to the second state, and the adjustment block 510 will move in the second direction relative to the limit block 520 until the adjustment block 510 abuts against the two limit blocks 520. At this time, under the action of the friction force between the adjustment block 510 and the limit blocks 520, the adjustment block 510 will not be able to continue moving under the restriction of the limit blocks 520, and the adjustment block 510, the limit block 520 and the second side of the wall 200 are relatively still, thereby keeping the wall sleeve 100 and the wall 200 relatively still, thereby completing the installation of the wall sleeve 100.

[0032] Only one operator is required to complete the entire installation process. When installing the reserved holes 210 with different radii, by setting the adjustment block 510 and the limit block 520 that can slide along the adjustment disk 400, the adjustment block 510 can be abutted against the second side of the wall 200 within the sliding range of the adjustment block 510 and the limit block 520. Then, under the action of the friction force between the adjustment block 510 and the limit block 520, the installation of the wall sleeve 100 is completed. This allows the wall sleeve 100 to be adapted to more walls 200 and has a wider range of use.

[0033] In this embodiment, the relative surfaces of the adjustment block 510 and the two limit blocks 520 around the first direction are both wedge-shaped surfaces, and when the adjustment block 510 moves in the second direction relative to the two limit blocks 520 toward the side away from the central axis of the wall sleeve 100, that is, when the adjustment block 510 moves outward relative to the two limit blocks 520, the adjustment block 510 can abut against the two limit blocks 520.

[0034] See attached Figure 5 As shown, in the initial state, there is a gap between the adjustment block 510 and the two limit blocks 520, and when the adjustment block 510 moves, it can drive the two corresponding limit blocks 520 to move synchronously. When the adjustment block 510 moves outward in the second direction relative to the two limit blocks 520, the wedge surface on the adjustment block 510 will move relative to the wedge surfaces on the two limit blocks 520, so that the adjustment block 510 can abut against the two limit blocks 520.

[0035] In this embodiment, the adjustment assembly 500 further includes a trigger block 530 and two trigger rods 540. A cavity 511 is provided on the adjustment block 510, and the trigger block 530 is installed in the cavity 511 through a first elastic member 531. The first elastic member 531 is arranged along the first direction, and the first elastic member 531 is a spring. In the initial state, the trigger block 530 extends toward one side of the second side.

[0036] The two trigger rods 540 are respectively installed in the cavity 511 through the second elastic member 541, which is arranged perpendicular to the first direction and is a spring. The two trigger rods 540 are arranged in a one-to-one correspondence with the two limit blocks 520. In the initial state, the second elastic member 541 is in a compressed state, and the two trigger rods 540 are extended out of the adjustment block 510 and plugged into the corresponding limit blocks 520, so that when the adjustment block 510 moves along the second direction, it can drive the two corresponding limit blocks 520 to move synchronously. Two receiving grooves 532 are provided on the trigger block 530, and the two receiving grooves 532 are arranged in one-to-one correspondence with the two trigger rods 540. When the adjustment block 510 abuts against the second side surface, the second side surface can cause the trigger block 530 to retract into the cavity 511 along the first direction, so that the trigger rod 540 can extend into the receiving groove 532 corresponding to it, and no longer be plugged into the limit block 520 corresponding to it, so that the adjustment block 510 can move in the second direction relative to the two limit blocks 520 corresponding to it.

[0037] Since there is a distance between the adjustment block 510 and the two limit blocks 520 in the initial state, and the two trigger rods 540 both extend out of the adjustment block 510 and are plugged into the corresponding limit blocks 520, when the adjustment block 510 moves, it can drive the two corresponding limit blocks 520 to move synchronously. When the adjustment block 510 abuts against the second side surface, the second side surface will prompt the trigger block 530 to retract into the cavity 511 along the first direction, so that the trigger rod 540 can extend into the corresponding receiving groove 532, and the second elastic member 541 is released, so that the trigger rod 540 is no longer plugged into the corresponding limit blocks 520, so that the adjustment block 510 can move in the second direction relative to the two corresponding limit blocks 520.

[0038] In this embodiment, the mounting disk 300 and the adjusting disk 400 are connected by a plurality of adjusting rods 600, and the plurality of adjusting rods 600 are evenly distributed around the first direction between the mounting disk 300 and the adjusting disk 400. The adjusting rods 600 have threaded sections, and the adjusting rods 600 are arranged along the first direction. Each adjusting rod 600 passes through the mounting disk 300 and is fixedly connected to the adjusting disk 400. Each adjusting rod 600 is sleeved with a first nut, and the first nut is threadably matched with the threaded section on the adjusting rod 600. In the initial state, the first nut abuts against the mounting disk 300.

[0039] In this embodiment, an adjusting rod 600 is provided. When in use, the adjusting rod 600 is prompted to move in the first direction by rotating the first nut. The movement of the adjusting rod 600 will drive the adjusting disk 400 to move synchronously, so that the adjusting disk 400 moves along the first direction toward or away from the mounting disk 300. Then, the spacing between the adjusting disk 400 and the mounting disk 300 in the first direction can be adjusted according to the thickness of the wall 200. When the trigger block 530 on the adjusting block 510 moves along the second direction through the reserved hole 210 to the wall 200, the second side surface of the wall 200 can abut against the trigger block 530 and retract the trigger block 530, thereby fine-tuning the distance between the adjusting disk 400 and the mounting disk 300 to adapt to the thickness of the wall 200.

[0040] In this embodiment, the adjustment assembly 500 further includes a transmission rod 550 and a rotating rod 560. The transmission rod 550 is a threaded rod, and the transmission rod 550 is arranged along the first direction. Each transmission rod 550 sequentially passes through the mounting plate 300 and the adjustment plate 400 along the first direction, so that the transmission rod 550 can move in the first direction relative to the mounting plate 300 and the adjustment plate 400. The transmission rods 550 of the plurality of adjustment assemblies 500 are connected by a ring frame 570. Each transmission rod 550 is sleeved with a second nut, and the second nut is threadedly matched with the transmission rod 550. In the initial state, the second nut abuts against the mounting plate 300. The rotating rod 560 is rotatably connected between the adjustment block 510 and the transmission rod 550 correspondingly arranged thereto.

[0041] In this embodiment, a transmission rod 550 and a rotating rod 560 are provided. When in use, the transmission rod 550 is prompted to move in the first direction by rotating the second nut. The movement of the transmission rod 550 will drive all the transmission rods 550 to move synchronously through the ring frame 570. The ring frame 570 moves toward the side close to the mounting plate 300 and causes the rotating rod 560 to rotate outward, thereby driving the adjustment block 510 corresponding to the rotating rod 560 to move along the second direction on the adjustment plate 400.

[0042] In this embodiment, the mounting plate 300 is sleeved on the wall sleeve 100 , and the mounting plate 300 includes two bodies, both of which are semi-annular, and the two bodies are butted and locked with the wall sleeve 100 by bolts.

[0043] In this embodiment, the adjustment disk 400 is provided with a plurality of adjustment slots, which are arranged along the second direction, and the plurality of adjustment slots are arranged one-to-one with the plurality of adjustment components 500, and each adjustment component 500 can slide in its corresponding adjustment slot. Four adjustment components 500 are arranged.

[0044] Specifically, the plurality of adjustment slots are arranged in one-to-one correspondence with the plurality of adjustment blocks 510 , and the adjustment blocks 510 can slide in the corresponding adjustment slots.

[0045] The two ends of the adjustment block 510 along the second direction are respectively called the first end and the second end. The first end is located on the side of the second end in the second direction close to the central axis of the wall sleeve 100 in the first direction, that is, the first end is located inside the second end. The first end is provided with a sliding protrusion, and the sliding protrusion is slidably matched with the adjustment groove. The size of the adjustment block 510 in the second direction is equal to the size of the adjustment groove in the second direction.

[0046] When the adjustment block 510 slides in the adjustment slot, the distance that the adjustment block 510 can extend out of the adjustment slot is equal to the size of the adjustment slot in the second direction. Figure 6 As shown, the distance that the trigger block 530 moves outward along the second direction with the adjustment block 510 is called L, the radius of the reserved hole 210 is called R, and the radius of the adjustment disk 400 is called r. When L>(Rr), the trigger block 530 on the adjustment block 510 can abut against the second side surface of the wall 200. Therefore, by expanding L as much as possible, the application range of the installation assembly of the wall bushing for power construction of this embodiment can be expanded.

[0047] In combination with the above embodiments, the specific working process is as follows:

[0048] When the wall sleeve 100 is installed on the wall 200, since the radius of the adjustment disk 400 is smaller than the radius of the reserved hole 210, the adjustment disk 400 can pass through the wall 200, so that the adjustment disk 400 and the installation disk 300 are respectively located on both sides of the wall 200 in the first direction, and the installation disk 300 is abutted against the first side surface of the wall 200.

[0049] Then, the first nut is rotated to move the adjusting rod 600 in the first direction. The movement of the adjusting rod 600 will drive the adjusting disk 400 to move synchronously, so that the adjusting disk 400 moves along the first direction toward or away from the mounting disk 300. The spacing between the adjusting disk 400 and the mounting disk 300 in the first direction is adjusted according to the thickness of the wall 200, so that when the trigger block 530 on the adjusting block 510 moves along the second direction through the reserved hole 210 to the wall 200, the second side surface of the wall 200 can abut against the trigger block 530 and retract the trigger block 530, thereby fine-tuning the distance between the adjusting disk 400 and the mounting disk 300 to adapt to the thickness of the wall 200.

[0050] Then, the second nut is rotated to cause the transmission rod 550 to move in the first direction. The movement of the transmission rod 550 will drive all the transmission rods 550 to move synchronously through the ring frame 570, so that the ring frame 570 moves toward the side close to the mounting plate 300 and the rotating rod 560 rotates outward, thereby driving the adjustment block 510 corresponding to the rotating rod 560 to move along the second direction on the adjustment plate 400.

[0051] Since there is a gap between the adjustment block 510 and the two limit blocks 520 in the initial state, and the two trigger rods 540 extend out of the adjustment block 510 and plug into the corresponding limit blocks 520, when the adjustment block 510 moves, it can drive the two corresponding limit blocks 520 to move synchronously, and the adjustment block 510 and the two limit blocks 520 slide along the reserved hole 210 in the second direction, and the adjustment block 510 does not abut against the second side surface of the wall 200. The adjustment assembly 500 is in the first state.

[0052] When the adjustment block 510 moves to abut against the second side of the wall 200, the adjustment assembly 500 switches to the second state, and the second side will cause the trigger block 530 to retract into the cavity 511 along the first direction, so that the trigger rod 540 can extend into the corresponding receiving groove 532, and the second elastic member 541 is released, and the trigger rod 540 is no longer plugged into the corresponding limit block 520, so that the adjustment block 510 can move in the second direction relative to the two corresponding limit blocks 520.

[0053] Afterwards, under the action of the friction force between the adjustment block 510 and the limit block 520, the adjustment block 510 will not be able to move further under the restriction of the limit block 520, and the end faces of the adjustment block 510 and the two limit blocks 520 close to one end of the second side in the first direction will also be locked with the second side of the wall 200 through friction. The adjustment block 510, the limit block 520 and the second side of the wall 200 are relatively still, thereby keeping the wall sleeve 100 and the wall 200 relatively still, completing the installation of the wall sleeve 100.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
