[0024] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A ventilation duct mounting clamp, such as Figures 1 to 4As shown, it includes two sets of hanging mechanisms 1, and the bottom ends of the two sets of hanging mechanisms 1 are fixedly connected with fixing mechanisms 2;

[0027] The hanging mechanism 1 includes a fixed block 101, the inner wall of the fixed block 101 is rotatably connected with a threaded rod 103, the outer wall of the threaded rod 103 is threadedly connected with a connecting rod 102, the connecting rod 102 is slidably connected to the inner wall of the fixed block 101, the end of the connecting rod 102 is fixedly connected with a connecting block 104, the inner wall of the connecting block 104 is rotatably connected with a rotating shaft 105, the outer wall of the rotating shaft 105 is fixedly sleeved with a fixing plate 106, the end of the fixing plate 106 is fixedly connected to the top of the fixing mechanism 2, the outer wall of the rotating shaft 105 is fixedly sleeved with a positioning tooth 107, the inner wall of the connecting block 104 is fixedly connected There is a guide rod 108, the outer wall sliding sleeve of the guide rod 108 is provided with a gear ring 109, the gear ring 109 is sleeved on the outside of the positioning tooth 107, the gear ring 109 is meshed with the positioning tooth 107, the outer wall of the guide rod 108 is sleeved with a return spring 110, one end of the return spring 110 is fixedly connected to the side wall of the gear ring 109, and the other end of the return spring 110 is fixedly connected to the inner wall of the connecting block 104, one end of the threaded rod 103 extends to the outside of the fixed block 101, and the end of the threaded rod 103 located outside the fixed block 101 is fixedly connected to the turning handle, and the outer wall of the turning handle is fixedly sleeved with a rubber sleeve.

[0028] The fixing block 101 is fixed to the wall by using bolts. During the installation of the ventilation duct, the ventilation duct is made of iron sheet, so there will be a certain degree of deformation. By rotating the threaded rod 103, the threaded rod 103 pushes the connecting rod 102 to move, and the position of the fixing mechanism 2 can be adjusted to a certain extent. The gear ring 109 can be pushed to compress the reset spring 110, so that the gear ring 109 is separated from the positioning tooth 107, and then the fixing plate 106 is pushed to flip, so that the fixing plate 106 drives the fixing mechanism 2 and the positioning tooth 107 is flipped, thereby adjusting the angle of the fixing mechanism 2 so that it can better fit the ventilation pipe during installation, and then by loosening the ring gear 109, the reset spring 110 rebounds and pushes the ring gear 109 to reset, so that the ring gear 109 and the positioning tooth 107 are engaged. At this time, the positioning tooth 107 is blocked by the ring gear 109, making it impossible for the positioning tooth 107 to rotate, and the positioning tooth 107 and the fixing plate 106 are fixed on the rotating shaft 105 at the same time, so at this time the fixing plate 106 cannot rotate, making the fixing mechanism 2 unable to rotate.

[0029] Please refer to Figure 1 and Figure 2The fixing mechanism 2 includes a guide rail 201, which is fixedly connected to the ends of the two groups of fixed plates 106. A slide groove 202 is provided at the bottom end of the guide rail 201. Two groups of sliders 203 are slidably connected to the inner wall of the slide groove 202. The bottom end of one group of sliders 203 is fixedly connected to a first clamping arm 204, and the bottom end of the other group of sliders 203 is fixedly connected to a second clamping arm 205. The side wall of the second clamping arm 205 is fixedly connected to a sliding bar 206. The first clamping arm 204 is slidably sleeved on the outer wall of the sliding bar 206. The bottom end of the sliding bar 206 is rotatably connected to two groups of limit pins 208. The limit pins 208 are provided with torsion springs at the connection with the second clamping arm 205. The bottom end of the first clamping arm 204 is provided with a plurality of groups of oblique teeth 207, which are consistent with the limit pins 208. The outer walls of the first clamping arm 204 and the second clamping arm 205 are respectively fixedly connected to a plurality of groups of rubber pads.

[0030] The first clamp arm 204 and the second clamp arm 205 are sleeved on the outside of the ventilation pipe, and then the first clamp arm 204 and the second clamp arm 205 are pushed closer to each other, so that the two sets of sliders 203 are closer to each other, and the sliding bar 206 slides toward the inside of the first clamp arm 204, presenting an entry Figure 2 During this process, the limit pin 208 is pushed by the bevel teeth 207 and flipped. When a group of bevel teeth 207 slides over the limit pin 208, the limit pin 208 is reset under the rebound push of the torsion spring, so that the limit pin 208 is blocked by the bevel teeth 207, so that the sliding sleeve cannot slide out of the first clamp arm 204, thereby preventing the first clamp arm 204 and the second clamp arm 205 from loosening outside the ventilation pipe.

[0031] When in use, the threaded rod 103 is rotated to push the connecting rod 102 to move, and the gear ring 109 is pushed so that the fixing plate 106 can be flipped, thereby adjusting the position and angle of the fixing mechanism 2, so that in the process of connecting the ventilation pipe and the mounting clamp together, the connection can be carried out more conveniently, and the adaptability of the mounting clamp during the installation process is improved, so that the mounting clamp can adapt to walls of different angles. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
