[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment: a bracket for installing a ventilation and smoke exhaust duct, comprising a support plate 1, a bottom plate 2 is arranged at the bottom of the support plate 1, a bidirectional screw 4 is rotatably connected inside the bottom plate 2, a left and right opposite slider 5 is threadedly connected in the middle of the bidirectional screw 4, two sliders 5 are slidably connected to the top of the bottom plate 2, and push plates 6 are fixedly connected to the tops of the two sliders 5, a bidirectional screw 27 is rotatably connected inside the support plate 1, a left and right opposite slider 28 is threadedly connected in the middle of the bidirectional screw 27, two sliders 28 are slidably connected to the bottom of the support plate 1, push plates 29 are fixedly connected at the bottoms of the two sliders 28, and the two push plates 6 are arranged between the two push plates 29, a mounting assembly is arranged between the support plate 1 and the bottom plate 2, a rebound assembly is arranged between the two push plates 6, a nut surface 21 is fixedly connected on the right sides of the bidirectional screw 4 and the bidirectional screw 27, and a nut surface 22 is fixedly connected at the bottoms of a plurality of threaded rods 10.

[0034] Put the ventilation and smoke exhaust pipe between the two push plates 6, rotate the lower nut surface 21 to drive the bidirectional screw 4 to rotate, and when the bidirectional screw 4 rotates, the thread drives the two sliders 5 to approach each other, and at the same time drives the two push plates 6 to approach each other and clamp the middle ventilation and smoke exhaust pipe. After the two push plates 6 are close to each other and clamped, rotate the upper nut surface 21 to drive the bidirectional screw 27 to rotate. When the bidirectional screw 27 rotates, the thread drives the two sliders 28 to approach each other, and at the same time drives the two push plates 29 to approach each other and clamp the two push plates 6 respectively for stability, thereby realizing the double clamping of the ventilation and smoke exhaust pipe, rotate the upper nut surface 21 in the opposite direction and drive the bidirectional screw 27 to rotate in the opposite direction, the thread drives the two sliders 28 to move away from each other, and the two push plates 29 will also move away from each other. The two push plates 6 will also move away from each other, and the clamping of the ventilation and smoke exhaust pipe will be released.

[0035] Reference Figure 1-Figure 3The mounting assembly includes a threaded rod 10 and a sleeve 11. The threaded rod 10 and the sleeve 11 are both provided in plurality. The sleeves 11 are respectively fixedly connected at the four corners of the bottom of the support plate 1. The plurality of sleeves 11 are respectively rotatably connected at the four corners of the middle of the bottom plate 2. The plurality of threaded rods 10 are respectively threadedly connected inside the plurality of sleeves 11. The four corners of the top of the bottom plate 2 are all fixedly connected with buffer pads 23. The plurality of threaded rods 10 are respectively rotatably connected inside the plurality of buffer pads 23.

[0036] After the two push plates 6 clamp the pipe, the base plate 2 is moved upward as a whole, and the multiple threaded rods 10 are aligned with the multiple sleeves 11 respectively, and the multiple nut surfaces 22 are rotated to thread the multiple threaded rods 10 into the multiple sleeves 11 to achieve the installation of the support plate 1 and the base plate 2, until the multiple sleeves 11 are against the multiple threaded rods 10 to prevent the sleeves 11 from hitting the top of the base plate 2. After the two push plates 6 are released from clamping, the multiple nut surfaces 22 are rotated in the opposite direction to thread the threaded rods 10 away from the sleeves 11 in the opposite direction to complete the disassembly.

[0037] Reference Figure 1 , Figure 6 and Figure 7 A mounting plate 15 is provided on the top of the support plate 1, a rotating column 16 is fixedly connected to the bottom of the mounting plate 15, and the bottom of the rotating column 16 is rotatably connected to the support plate 1. Evenly distributed card slots 18 are provided on the top of the support plate 1, and the rotating column 16 is arranged between multiple card slots 18. A lifting handle 17 is slidably connected to the front end of the rotating column 16, and the lifting handle 17 is engaged in one of the card slots 18. Mounting holes 3 are provided at the four corners of the middle of the mounting plate 15, and a connecting block 19 is fixedly connected to the rear side of the lifting handle 17. The connecting block 19 is slidably connected to the inside of the mounting plate 15, and a spring 20 is fixedly connected to the top of the connecting block 19.

[0038] The mounting plate 15 is installed through the multiple mounting holes 3. After the mounting plate 15 is installed, hold the lifting handle 17 and lift it upward, while driving the connecting block 19 to slide upward in the rotating column 16 and squeeze the spring 20. At this time, the lifting handle 17 will leave one of the engaged slots 18, and then the support plate 1 is rotated through the rotating column 16. When it is rotated to the required angle, release the lifting handle 17. At this time, the spring 20 will rebound, push the connecting block 19 downward, and drive the lifting handle 17 to engage in a slot 18 at the current position to stabilize the support plate 1.

[0039] Reference Figure 4-Figure 5 The rebound component includes a clamping block 12 and a spring 13. The clamping blocks 12 are set to two, and the spring 13 is set to multiple. One ends of the multiple springs 13 are respectively fixedly connected to the adjacent sides of the two push plates 6, and the other ends of the multiple springs 13 are respectively fixedly connected to the opposite sides of the two clamping blocks 12. The adjacent sides of the two clamping blocks 12 are respectively fixedly connected with uniformly distributed rubber pads 14.

[0040] When two push plates 6 are used to clamp the ventilation and smoke exhaust pipe, two clamping blocks 12 are used to press against the ventilation and smoke exhaust pipe, and multiple rubber pads 14 are used to increase friction to avoid unstable clamping. Multiple clamping blocks 12 are used for rebound and shock absorption to avoid vibration damage to the ventilation and smoke exhaust pipe.

[0041] Working principle: when in use, the mounting plate 15 is installed through the multiple mounting holes 3, and then the ventilation and smoke exhaust duct is placed between the two push plates 6, and the two sliders 5 are driven to approach each other through the thread of the bidirectional screw 4, and at the same time, the two push plates 6 will also approach each other and clamp the ventilation and smoke exhaust duct. After clamping, the bottom plate 2 is moved upward, and the multiple threaded rods 10 are respectively threaded into the multiple sleeves 11 through the multiple nut surfaces 22 to complete the installation of the support plate 1 and the bottom plate 2, and then the two sliders 28 are driven to approach each other through the thread of the bidirectional screw 27, and at the same time, the two push plates 29 will also approach each other and clamp the two push plates 6, so as to realize the double clamping of the ventilation and smoke exhaust duct. When disassembly is required, the two sliders 28 are driven to move away from each other through the reverse direction thread of the bidirectional screw 27, and at the same time, the two push plates 29 are respectively driven to move away from the two push plates 6, and then the bidirectional screw 27 is used to disassemble the two sliders 28. The screw rod 4 drives the two sliders 5 away from each other in the opposite direction, and drives the two push plates 6 away from each other and releases the clamping of the ventilation and smoke exhaust pipe, and then rotates the multiple nut surfaces 22 in the opposite direction to make the multiple threaded rods 10 threadedly leave the multiple sleeves 11, completing the disassembly of the support plate 1 and the base plate 2 and the disassembly of the ventilation and smoke exhaust pipe. Before installing and clamping the ventilation and smoke exhaust pipe, hold the lifting handle 17 and lift it upward and leave one of the engaged slots 18, and at the same time make the connecting block 19 slide upward in the rotating column 16 and squeeze the spring 20, and then rotate the support plate 1, and release the lifting handle 17 after rotating to the required position. At this time, the spring 20 rebounds the connecting block 19, and at the same time drives the lifting handle 17 to push downward and engage into one of the slots 18, thereby fixing the support plate 1, so as to facilitate the installation of the ventilation and smoke exhaust pipe at another angle.
