Detailed Implementation

[0037] The accompanying drawings provide a more detailed description of an aluminum foil signboard installation device that does not require a pedal, but this is not intended to limit the scope of the application.

[0038] A novel aluminum foil sign installation device without a foot pedal includes a sign installation assembly and a foot pedal assembly that are connected to each other.

[0039] The sign installation assembly includes a first support frame 1 connected to the pedal assembly. A sign clamping device is connected to the inner side of the first support frame 1. One side of the sign clamping device has two vertically arranged clamping bolt tightening devices, and the other side has a limiting frame 3 fixed to the inner side of the first support frame 1. The opening of the limiting frame 3 faces inward, and the limiting frame 3 is arranged opposite to the clamping bolt tightening devices. Clamps 18 are clamped inside the limiting frame 3. Specifically, the limiting frame 3 is an E-shaped or U-shaped plate with an inward-facing opening. Two clamps 18 are generally threaded through the sign 17, and the bottom surfaces of the two clamps 18 are formed by the limiting frame 3. This prevents the clamps 18 from shifting during pedaling; therefore, the limiting frame 3 preferably uses an E-shaped plate. Simultaneously, the gap between the inner end face of the limiting frame 3 and the utility pole 32 is less than 1 cm, so the limiting frame 3 can also serve a guiding function during the tightening of the clamps 18.

[0040] The two clamp bolt tightening devices are fixedly connected by the vertically arranged first connecting plate 7.

[0041] A horizontally arranged first slide rod 701 is fixed on the outer side of the middle of the first connecting plate 7. A support plate 102 is fixed on the first support frame 1. The end of the first slide rod 701 passes through the through hole on the support plate 102 and is provided with a limiting end. A first spring 8 is sleeved on the first slide rod 701. The two ends of the first spring 8 abut against the first connecting plate 7 and the support plate 102 respectively.

[0042] The clamp bolt tightening device includes a second support frame 9 fixedly connected to the first connecting plate 7. The second support frame 9 has a second sliding rod 10 that moves axially along its axis. A sleeve 1001 is provided at the end of the second sliding rod 10. The inner cavity of the sleeve 1001 is hexagonal, matching the shape of the tightening bolt 1802. The sleeve 1001 is used to engage the tightening bolt 1802 of the clamp 18 and drive the tightening bolt 1802 to rotate.

[0043] The second support frame 9 is equipped with a telescopic device 12 and a first motor (13).

[0044] The telescopic device 12 is used to control the movement of the sleeve 1001 and to control the sleeve 1001 to loosen and loosen the tightening bolt 1802. The first motor 13 drives the sleeve 1001 to rotate.

[0045] Furthermore, a second sleeve 901 is fixed on the second support frame 9, the second sleeve 901 is sleeved on the second slide rod 10, and a second spring 11 is sleeved on the second slide rod 10. The two ends of the second spring 11 abut against the second sleeve 901 and the sleeve 1001, respectively.

[0046] The second slide bar 10 is fixed with a polygonal rod 1002 on the side opposite to the sleeve 1001. A rotating sleeve 15 is sleeved on the polygonal rod 1002, and a third sleeve 902 that is fixedly connected to the second support frame 9 is sleeved at the end of the rotating sleeve 15.

[0047] The output end of the first motor 13, which is fixedly connected to the second support frame 9, drives the rotating sleeve 15 to rotate through the first synchronous belt 14.

[0048] The polygonal rod 1002 has a round rod 1003 at one end away from the second sliding rod 10. The round rod 1003 has limiting rings protruding at both ends along its axial direction. A fourth sleeve 1201 is sleeved on the round rod 1003. The fourth sleeve 1201 is fixedly connected to the telescopic rod of the telescopic device 12.

[0049] The front top head 16 is fixed on the second support frame 9, and the front top head 16 and the sleeve 1001 are arranged at intervals relative to each other.

[0050] The telescopic device 12 can be an electric cylinder or an electromagnet. In use, the telescopic device 12 pulls the sleeve 1001 back through the fourth sleeve 1201, widening the distance between the sleeve 1001 and the front head 16. Then, the fastening part 1801 of the clamp 18 is locked between the sleeve 1001 and the front head 16. The telescopic device 12 is de-energized, and the sleeve 1001 moves towards the front head 16 under the action of the second spring 11 until it is fitted onto the tightening bolt 1802.

[0051] The first motor 13 drives the tightening bolt 1802 to rotate through the sleeve 1001, thereby reducing the inner diameter of the clamp 18 and making it clamp tightly onto the utility pole 32.

[0052] After tightening the clamp 18, the telescopic device 12 pulls the sleeve 1001 back again, disengaging it from the tightening bolt 1802. As the clamp bolt tightening device rotates the tightening bolt 1802 of the clamp 18, the inner diameter of the clamp 18 gradually decreases. The clamp bolt tightening device moves towards the utility pole 32. After the sleeve 1001 separates from the tightening bolt 1802, under the push of the first spring 8, the clamp bolt tightening device moves away from the utility pole 32, completely disengaging from the clamp 18.

[0053] The signboard snap-fit ​​device includes two oppositely arranged snap-fit ​​plates 4, with abutment plates 401 perpendicularly connected to each other on the snap-fit ​​plates 4. The signboard 17 is snapped between the two snap-fit ​​plates 4, and the front of the signboard 17 abuts against the abutment plate 401 in parallel.

[0054] A spacing adjustment device is provided between the two clamping plates 4 to accommodate signs 17 of different widths. The spacing adjustment device includes a nut sleeve 5, and a screw 403 is fixed on each opposite side of the two clamping plates 4. The threads on the two screws 403 are turned in opposite directions, and both screws 403 are threadedly connected to the nut sleeve 5.

[0055] The card plate 4 is fixed with a sliding plate 402 on the side facing the first support frame 1. The first support frame 1 is provided with a sliding groove 101 arranged along the axial direction of the screw 403. The sliding plate 402 is slidably disposed inside the sliding groove 101.

[0056] In order to guide the screw 403, a first sleeve 6 is fitted on the screw 403 and fixedly connected to the first support frame 1.

[0057] The pedal assembly includes at least two layers of bending connecting frames 26, with adjacent layers of bending connecting frames 26 fixedly connected by a vertical plate 30.

[0058] Each layer includes two opposing bending connecting frames 26. One end of each frame is hinged, and the other end is connected via a connecting rod 27. Both frames are rotatably connected to a base plate 2 fixed below the first support frame 1 via connecting rotating rods 29. The base plate 2 is equipped with a power supply assembly and a control module. The control module is electrically connected to the electrical components included in the aluminum foil signboard pole-free installation device. The control module contains a remote transmission module and a receiving module, which wirelessly connect to the control terminal of the ground operator. The control terminal can be a mobile app or a dedicated remote control.

[0059] Each bending connecting frame 26 adopts a double-layer clamping plate structure. Two bending connecting frames 26 on the same layer are detachably connected at one end. One bending connecting frame 26 has a socket 2602 on the two clamping plates at its end, and the other bending connecting frame 26 has a vertically arranged insert 2603 at its end. During connection, the insert 2603 is inserted between the two sockets 2602, and then the connecting rod 27 passes through the socket 2602, the insert 2603, and the socket 2602 below in sequence to connect the two bending connecting frames 26 on the same layer.

[0060] The two bent connecting frames 26 on the same layer are connected by I-shaped rods 28. The function and connection method of the two vertical parts of the I-shaped rod are similar to those of the above-mentioned insertion tube 2603. The two vertical parts of the I-shaped rod 28 are each provided with connecting rotating rods 29.

[0061] The inner side of the bending connecting frame 26 is provided with several climbing devices at intervals, and the rollers 22 of the climbing devices abut against the outer wall of the utility pole 32. In this embodiment, each layer has six climbing devices arranged in a circular array around the axis of the utility pole 32, and three climbing devices are fixedly connected to each bending connecting frame 26.

[0062] The climbing device includes a third support frame 19, with a fourth support frame 20 spaced apart on the inner side of the third support frame 19. The third support frame 19 is U-shaped and guides the sliding of the fourth support frame 20. A third sliding rod 2001 is fixed to the side of the fourth support frame 20 facing the third support frame 19. The end of the third sliding rod 2001 passes through the through hole 1901 of the third support frame 19 and is threadedly connected to a limit connecting bolt 25. The design of the connecting bolt 25 not only prevents the third sliding rod 2001 from separating from the third support frame 19, but also facilitates the overall disassembly and replacement of the fourth support frame 20. The third sliding rod 2001 is arranged radially along the utility pole 32.

[0063] The third slide bar 2001 is fitted with a second spring 21, and the two ends of the second spring 21 abut against the third support frame 19 and the fourth support frame 20 respectively.

[0064] The roller 22 is located at one end of the fourth support frame 20 away from the third support frame 19, and a fifth sleeve 2002, which is fixedly connected to the fourth support frame 20, is sleeved on the central shaft of the roller 22.

[0065] A pulley 2201 is connected to the end of the central shaft on one side of the roller 22. A second motor 23 is fixed on the fourth support frame 20. The second motor 23 drives the roller 22 to rotate through the second synchronous belt 24 connected to the pulley 2201.

[0066] Because the utility pole 32 is conical, its outer diameter decreases as it ascends. Therefore, the second spring 21 ensures that the roller 22 remains in contact with the outer wall of the utility pole 32. Simultaneously, the climbing assembly has two layers of staggered climbing devices. In the event of a malfunction and the climbing assembly cannot move, the force of the second spring 21 and the conical shape of the utility pole 32 ensure that it remains in place and does not fall.

[0067] The third support frame 19 is fixedly connected to the bending connection frame 26 via the second connecting plate 2601. The top of the upper bending connection frame 26 is fixed with a support 31. After the two bending connection frames 26 are closed, the top surface of the support 31 abuts against the bottom surface of the base plate 2 to support the base plate 2.

[0068] In use, first assemble and fix the climbing arm assembly onto the utility pole 32, then snap the sign 17 between the two clamping plates 4. The tightening end of the clamp 18 passes through the sign 17, is fitted onto the utility pole 32, and then threaded into the fastening part 1801 to connect with the tightening bolt 1802. Next, the sleeve 1001 is fitted onto the end of the tightening bolt 1802, and together with the front top head 16, the fastening part 1801 is tightened. Afterwards, the climbing device moves the entire assembly to the designated position on the utility pole 32, and the clamp 18 is tightened, completing the installation of the sign 17.

[0069] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
