The invention discloses a trailer spare tire mounting bracket, which belongs to the technical field of trailer spare tire mounting, and comprises two support frames, the two support frames are respectively provided with a flat shoulder, and each flat shoulder is provided with a first long hole; a supporting plate is suspended below the two supporting frames, and two second long holes are symmetrically formed in the supporting plate; two locking rods are arranged on the supporting plate; a base block is fixed to the upper surface of the square shoulder, a penetrating groove is formed in the base block, and a plurality of check blocks are slidably connected to the base block. Through flexible alignment of the second long hole and the tire screw hole, rapid installation of the spare tire is achieved. After the locking rod penetrates through a tire screw hole, the locking rod is matched with fastening of the nut, and the check block is combined with the first spring to form a transverse movement preventing system. And when the locking rod penetrates through the penetrating groove, the locking rod is limited to the fixed position of the penetrating groove through the check block, transverse movement of the locking rod in the transportation process is effectively prevented, and the stability of spare tire fixing is improved.

    本发明公开了一种挂车备胎安装支架,属于挂车备胎安装技术领域,包括两个支撑架,两个支撑架分别具有一平肩,每个平肩上均开设有第一长孔;两个支撑架的下方悬吊有托板,托板上对称开设有两个第二长孔;托板上设置有两个锁固杆;平肩的上表面固定有基块,基块上开设有贯穿槽,基块上滑动连接有多个挡块;本发明通过第二长孔与轮胎螺孔的灵活对位,实现了备胎的快速安装。锁固杆穿过轮胎螺孔后,配合螺帽的紧固,并且挡块与第一弹簧组合,构成了防横向移动系统。在锁固杆穿过贯穿槽时,挡块将锁固杆限定在贯穿槽的固定位置,有效防止其在运输过程中的横向移动,提升了备胎固定的稳定性。
