[0044] The top of support flange seat 4 is provided with flange seat convex ring 41 (as Figures 3-4 And Figure 7 ), and the flange seat convex ring 41 is connected with the top cover 31 of the sleeve support 3 through the first fixing bolt 11 to fix and install the support flange seat 4 in the sleeve support 3, and the bottom of the support flange seat 4 is inclined.

[0045] The driving bolt 5 passes through the top cover 31 of the sleeve support 3 and the support flange seat 4 from top to bottom and is threadedly connected with the driving block 7, the driving block 7 is located at the bottom of the support flange seat 4, and the driving block 7 and the support flange seat 4 always keep a gap fit. The first anti-loosening nut 8 is threadedly connected at the bottom of the driving block 7, and the first anti-loosening nut 8 can effectively prevent the driving block 7 from falling off. When the driving block 7 moves to the lowermost position, the first anti-loosening nut 8 keeps a gap of 1-2 mm with the driving block 7 to avoid collision and falling off.

[0046] The plurality of movable clamping blocks 6 are radially and slidingly arranged between the bottom of the support flange seat 4 and the inner wall of the sleeve support 3. One end of each movable clamping block 6 is provided with an inclined surface which is in wedge-shaped sliding fit with the bottom of the support flange seat 4. After the sleeve support 3 is sleeved on the outer diameter of the top end of the collapsible rod member 1, the top end of the collapsible rod member 1 is arranged between the movable clamping blocks 6 and the side wall of the sleeve support 3, as shown in Figure 7 .

[0047] The driving block 7 is provided with a plurality of first through holes 71 in the circumferential direction (as Figures 5-6 ), and the plurality of axial guide columns 9 pass through the first through holes 71 from bottom to top and are fixedly connected with the flange seat convex ring 41. The bottom of the axial guide column 9 is connected with the third anti-loosening nut 10 which has a width greater than the first through hole 71. Preferably, the axial guide column 9 and the third anti-loosening nut 10 are integrally formed as a stainless steel bolt. The movement of the driving block 7 is limited by the axial guide column 9, so as to avoid synchronous rotation of the driving block 7 with the rotation of the driving bolt 5, and thus the driving block 7 only moves up and down during the rotation of the driving bolt 5.

[0048] In an optional embodiment, the driving bolt 5 is provided with a rotating force applying part 51 on the upper surface of the top cover 31 (as Figure 7 ). The rotating force applying part 51 is provided with an outer hexagonal or non-circular special-shaped wrench hole (for example, an inner hexagonal, a key-shaped, a cross-shaped or other shaped wrench hole). The outer hexagonal or wrench hole can facilitate the rotation of the driving bolt 5. A second anti-loosening nut 12 is also mounted on the driving bolt 5 close to the lower surface of the top cover 31. The second anti-loosening nut 12 can prevent the driving bolt 5 from loosening, so as to maintain the relative position between the driving bolt 5 and the sleeve support 3.

[0049] In an optional embodiment, the bottom of the support flange seat 4 is conical (as Figure 7 ). Two movable clamping blocks 6 are symmetrically arranged between the bottom of the support flange seat 4 and the inner wall of the sleeve support 3, and the axial guide column 9 passes through the gap between the side walls of the two movable clamping blocks 6 and is fixedly connected with the flange seat convex ring 41. The inner side of the movable clamping block 6 is provided with a semi-conical hole 61 which is in conical sliding fit with the bottom of the support flange seat 4 (as Figure 8When the driving block 7 drives the movable clamping block 6 to move up and down, the movable clamping block 6 is wedge-shaped matched with the flange seat 4, and then the movable clamping block 6 is moved up (or down) while sliding outward (or inward).

[0050] In an optional embodiment, the lower surface of the movable clamping block 6 is provided with a plurality of threaded holes 62 (as shown in Figure 8 ), each threaded hole 62 is threadedly connected with a radial guide bolt 13, the driving block 7 is circumferentially provided with a plurality of waist-shaped holes 72, the length direction of the waist-shaped hole 72 is consistent with the radial direction of the driving block 7, the radial guide bolt 13 passes through the waist-shaped hole 72 downward and is connected with a fourth anti-loosening nut 14 at the bottom of the radial guide bolt 13. The radial guide bolt 13 and the fourth anti-loosening nut 14 are both made of stainless steel. The radial guide bolt 13 plays a guiding role in the internal and external sliding of the movable clamping block 6, and the length of the waist-shaped hole 72 can also be used to limit the radial expansion distance of the movable clamping block 6, so as to avoid excessive clamping force or insufficient clamping force.

[0051] The working principle of the utility model is as follows: first, the sleeve support 3 provided with the clamping device is inverted and buckled on the top of the easy-to-fold rod 1, at this time, the top end side wall of the easy-to-fold rod 1 is located between the side wall of the sleeve support 3 and the movable clamping block 6 and is gap matched with each other. A wrench or other rotating tools is connected with the rotating force applying part 51, when the driving bolt 5 is rotated in the tightening direction (for example, clockwise), since the driving block 7 is provided with the threaded hole which is threadedly matched with the driving bolt 5, the rotating driving bolt 5 drives the driving block 7 to move upward, the driving block 7 is connected with the radial guide bolt 13 between the driving block 7 and the movable clamping block 6, so the movable clamping block 6 also moves upward. In addition, since the contact surface between the movable clamping block 6 and the flange seat 4 of the support is an inclined surface, the movable clamping block 6 also moves outward while moving upward, when the movable clamping block 6 moves outward by a certain distance, the normal pressure F1 between the side wall of the movable clamping block 6 and the inner wall of the easy-to-fold rod 1 is also larger and larger, and the static friction f is also larger and larger, so that the clamping effect is achieved, and the sleeve support 3 is fastened on the top of the easy-to-fold rod 1. When the driving bolt 5 is rotated counterclockwise, the loosening effect is achieved, and the sleeve support 3 can be easily disassembled from the top of the easy-to-fold rod 1.

[0052] Figures 9-11 The utility model discloses an airport pavement facility mounting support, which can be used for mounting various airport pavement facilities 2, including but not limited to various sensors, warning lights, alarms and the like.

[0053] The utility model discloses simple structure, convenient adjustment, low in cost, stable and reliable performance, sleeve support adopts stainless steel material, prevents rust, and the inside adopts aluminium material, and the whole structure is light and handy. The whole support is fixedly connected or separated with the easy-to-fold rod piece 1 through adjusting sleeve support top screw.

[0054] The utility model discloses airport pavement facility installation support outside except driving bolt, does not have any other exposed bolt, nut and so on foreign matter, driving bolt is installed on sleeve support top cap and does not fall off, and the inside rotary clamping device also is equipped with a variety of anti -drop nuts, effectively avoid the bolt loss or drop in the runway and cause safety accident. Even if anti -drop nut produces the drop, will only drop to the inside of easy-to-fold rod piece, will not drop on the airport road, further guarantees the airport safety.

[0055] The above describes the preferred embodiment of the utility model. It is understood that the utility model is not limited to the above specific implementation, and the equipment and structure not described in detail should be understood as being implemented in the ordinary way in the art. Any skilled person in the art can make many possible changes and modifications to the technical solution of the utility model or modify it into equivalent embodiments without departing from the scope of the utility model, which does not affect the essential content of the utility model.
