[0029] Example 1

[0030] This embodiment provides an adjustable ball head support frame for a car trunk, such as Figure 1 As shown, it comprises a hydraulic support rod 1, both ends of which are fixedly mounted with docking ball heads 2, and a spherical groove 3 is provided inside the docking ball head 2;

[0031] like Figure 2As shown, a ball head support frame 4 is arranged at the internal spherical groove 3 of the docking ball head 2, and the ball head support frame 4 includes a bolt 41, a head cover plate 42, a docking piece 43 and an adjusting ring 45. Two bolts 41 are arranged, and the two bolts 41 are respectively arranged on the trunk and the rear cover plate of the car. One end of the bolt 41 away from the head cover plate 42 is threadedly connected with a supporting square plate 5. Two supporting square plates 5 are arranged, and the two supporting square plates 5 are respectively fixed to the trunk and the rear cover plate of the car by bolts.

[0032] like Figure 3 and 4 As shown, the end of the bolt 41 is fixedly mounted on the head cover plate 42, and a plurality of docking pieces 43 are provided, and the plurality of docking pieces 43 are distributed at equal angles in a ring shape on the shaft of the bolt 41, and the end of the docking piece 43 is fixedly connected to the head cover plate 42, and the docking piece 43 is clamped with the spherical groove 3 inside the docking ball head 2, thereby fixing the position of the docking piece 43 and the docking ball head 2, that is, the two ends of the hydraulic support rod 1 are connected to the trunk and the rear cover plate of the car.

[0033] like Figure 3 As shown, the inner ring of the adjusting ring 45 is threadedly connected to the bolt 41, and the head cover plate 42 and the adjusting ring 45 clamp the docking piece 43. The docking piece 43 adopts an arc structure. The adjusting ring 45 moves on the bolt 41 and clamps the docking piece 43 together with the head cover plate 42 to deform it. The docking piece 43 bends and the curvature of its outer arc surface changes, so that it can adapt to docking ball heads 2 of different specifications, that is, it can adapt to hydraulic support rods 1 of different sizes.

[0034] The adjusting ring 45 is rotatably connected to the side of the head cover plate 42 with the intermediate pressure ring 44, and the end of the docking piece 43 is fixedly connected to the intermediate pressure ring 44. The adjustment ring 45 moves to drive the intermediate pressure ring 44 to move and clamp the docking piece 43. Since the adjusting ring 45 sits on the bolt 41 and needs to rotate to move, in order to prevent the docking piece 43 from being deformed by rotation, the intermediate pressure ring 44 is used as an intermediate piece.

[0035] In this embodiment, the user rotates the adjustment ring 45 to move the intermediate pressure ring 44 toward the head cover plate 42, and the distance between the intermediate pressure ring 44 and the head cover plate 42 changes, so that the docking piece 43 bends, changing the curvature of the outer arc surface of the docking piece 43 so that the outer arc surface of the docking piece 43 matches the spherical groove 3 inside the docking ball head 2 to adapt to hydraulic support rods 1 of different specifications.

[0036] Example 2

[0037] Based on the first embodiment, this embodiment provides an adjustable ball head support frame for a car trunk, such as Figure 3As shown, a limit plate 46 is fixedly installed at the shaft of the bolt 41, and the limit plate 46 is located between the head cover plate 42 and the middle pressure ring 44. The limit plate 46 prevents the adjustment ring 45 from moving too much, causing the docking piece 43 to bend beyond its limit and making the docking piece 43 unable to recover.

[0038] like Figure 3 As shown, a guide groove 48 is provided on the limit plate 46, and a guide rod 47 is fixedly installed on the side of the intermediate pressure ring 44 away from the adjustment ring 45. The guide rod 47 penetrates the limit plate 46 and is slidably connected to the guide groove 48. The guide rod 47 cooperates with the guide groove 48, so that the intermediate pressure ring 44 will not be driven to rotate by the adjustment ring 45 due to friction.

[0039] The bolt 41 is engraved with digital scales, the head cover plate 42 adopts an umbrella-shaped structure, and the inner arc surface of the docking piece 43 contacts the head cover plate 42. Remove the bolt 41 from the supporting square plate 5, and then remove the ball head support frame 4 as a whole, and compare it with the docking ball head 2 at the end of the purchased hydraulic support rod 1. Rotate the adjustment ring 45 to bend the docking piece 43 to match the spherical groove 3 inside the docking ball head 2, observe the scale on the bolt 41, and then rotate the adjustment ring 45 to remove the docking piece 43 from the spherical groove 3. The bolt 41 is used as a scale to adjust the position of the adjustment ring 45.

[0040] In this embodiment, the adjustment ring 45 is limited by the limit plate 46 to prevent the docking piece 43 from being bent beyond the limit and unable to recover, and cooperates with the guide rod 47 and the guide groove 48 to prevent the middle pressure ring 44 from being driven to rotate by the adjustment ring 45 when moving, thereby preventing the docking piece 43 from being twisted and unusable due to the rotation of the middle pressure ring 44.

[0041] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
