This technology has a simple structure and a light weight. Among products of the same weight, it has a better load-bearing capacity, but the above technology still has problems in use due to structural limitations:

[0004] In the above technology, when placed on a rugged ground, each support rod is located at a different height, so that each support rod has a different deflection angle. If the supporting force of each support rod is insufficient, a one-way tilt accident is very likely to occur. The above technology only relies on the gripping force of the foot and the ground to provide support force for a single support rod. However, when encountering sand, gravel, cement and other ground surfaces, the foot cannot grip the ground, so that the support force provided to a single support rod is limited, which is not conducive to maintaining the stability of the tripod. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that the foot seat encounters gravel, cement and other ground surfaces and cannot provide sufficient supporting force for a single supporting rod body, and thus proposes a fire rescue bracket.

[0010] A limiting mechanism, which is arranged on the mounting seat and is used to limit the rotating shaft;

[0011] The spreading mechanism is arranged on the main support rod and is used to spread the two auxiliary support rods.

[0012] Preferably, the limiting mechanism comprises:

[0014] Preferably, one end of the rotating shaft is movably sleeved in two arc-shaped grooves, and the two limit blocks are fixedly connected via threaded holes and bolts.

[0015] Preferably, the expansion mechanism comprises:

[0016] A fixed ring, an adjusting thread and a nut, wherein the fixed ring is fixedly sleeved at the middle end of the main support rod, the adjusting thread is opened at the lower end of the main support rod, and the nut is threadedly connected to the adjusting thread;

[0017] A rotating circular groove, an annular rotating member and a connecting rod, wherein the rotating circular groove is opened on the nut, the annular rotating member is arranged in the rotating circular groove, and two ends of the two connecting rods are respectively arranged on the annular rotating member and the auxiliary support rod.

[0029] Reference Figure 1-Figure 5 A fire rescue bracket, comprising a mounting seat 1, as shown in the attached Figure 1 As shown, four placement slots are provided on the mounting base 1, and a lifting ear is fixedly connected to the upper end of the mounting base 1, through which the tripod can be lifted, and a manual winch is fixedly connected to the lower end of the mounting base 1, and objects are lifted by the manual winch, and a rotating block 2 and a rotating shaft 3 are provided on the mounting base 1, and the four rotating blocks 2 are movably sleeved in the four placement slots respectively, and the four rotating shafts 3 are fixedly connected to the four rotating blocks 2 respectively, and the four rotating shafts 3 are rotatably connected to the four placement slots respectively;

[0030] A main support rod 4 and an auxiliary support rod 5 are also provided on the mounting base 1. The four main support rods 4 are fixedly connected to the four rotating blocks 2 respectively. The two auxiliary support rods 5 are respectively arranged on both sides of a main support rod 4, and the two auxiliary support rods 5 can auxiliary support the main support rod 4 through the spreading movement to avoid the accident of unidirectional tilt of the tripod; a limiting mechanism is arranged on the mounting base 1, and it is used to limit the rotating axis 3; an spreading mechanism is arranged on the main support rod 4, and it is used to spread the two auxiliary support rods 5.

[0031] The limiting mechanism includes a vertical limiting groove 6, a limiting block 7 and a threaded hole 8. The two vertical limiting grooves 6 are both opened at the side ends of the mounting seat 1. The two limiting blocks 7 are respectively slidably sleeved in the two vertical limiting grooves 6, and the two limiting blocks 7 are each provided with an arc groove at one opposite end, thereby fitting with the arc end surface of the rotating shaft 3. The two threaded holes 8 are respectively opened in the two limiting blocks 7.

[0032] As attached Figure 1 As shown, one end of the four rotating shafts 3 extends out of the mounting seat 1, and two limit blocks 7 are used to abut against the extended end of one rotating shaft 3, and the two limit blocks 7 are fixedly connected by threaded holes 8 and bolts.

[0033] The opening mechanism includes a fixed ring 9, an adjusting thread 10 and a nut 11. The fixed ring 9 is fixedly sleeved at the middle end of the main support rod 4, the adjusting thread 10 is opened at the lower end of the main support rod 4, and the nut 11 is threadedly connected to the adjusting thread 10. The nut 11 can be rotated on the adjusting thread 10 by hand, so that the nut 11 rotates and moves linearly at the same time;
