Description

Technical Field

[0001] This utility model relates to the field of HVAC duct installation technology, and in particular to a building HVAC duct installation bracket. Background Technology

[0002] Building heating, ventilation and air conditioning (HVAC) pipes refer to pipes installed inside buildings for heating, ventilation and air conditioning systems. During the installation process, HVAC pipes need to be fixed by mounting brackets.

[0003] For example, Chinese patent application CN202320110841.2 discloses a heating, ventilation, and air conditioning (HVAC) duct installation bracket. Specifically, when using the bracket, expansion bolts are driven into the top of the wall and align with the mounting holes on the mounting plate. This allows the bracket to be positioned at the top of the wall where the HVAC duct is installed. The bracket is then inserted into the mounting opening and slid inwards. Pulling the ring causes the operating rod to compress the spring on the movable plate, simultaneously causing the limiting block to retract. After one side of the bracket's outer surface slides against the inner wall of the mounting opening, the support plate slides downwards, causing the positioning block to engage. Insert the ring into the positioning groove, release the ring, and the spring will return to its original position, pushing the movable plate to engage the limiting block in the limiting groove. This completes the connection between the support plate and the mounting bracket. Similarly, disassembly is possible. The structure is simple to operate and flexible to use. It effectively improves the ease of operation when maintaining or replacing HVAC pipes. Place the HVAC pipe into the clamping groove on top of the fixing seat, cover the top of the HVAC pipe with the positioning seat, ensuring the clamping groove fits against the top of the HVAC pipe. Simultaneously, pass the positioning screw through the positioning hole and tighten the fastening nut onto the positioning screw to achieve the positioning and fixing of the HVAC pipe. However, the following technical issues exist:

[0004] The HVAC pipes are clamped by the cooperation of nuts and screws. However, in actual operation, multiple nuts need to be rotated, so the above structure is quite cumbersome to fix the HVAC pipes. Utility Model Content

[0005] To address the cumbersome installation process for fixing HVAC ducts in the prior art, as mentioned in the background section, this utility model provides the following technical solution:

[0006] A building heating, ventilation and air conditioning (HVAC) pipe installation bracket includes two clamping structures for clamping the HVAC pipes;

[0007] The upper end of the clamping structure is equipped with a fixing structure for limiting the position of the two clamping structures.

[0008] The fixing structure includes an adjustment component for limiting the position of the right clamping structure, and a locking component for locking the position of the right clamping structure is installed at the left end of the adjustment component.

[0009] Furthermore, the two clamping structures are arranged symmetrically from left to right. Each clamping structure includes an arc-shaped plate, the inner wall of which is equipped with an anti-slip pad. A connecting rod is installed on one side of the arc-shaped plate, and the connecting rod is a square rod with a positioning hole in the middle.

[0010] Furthermore, the fixing structure includes an I-beam for limiting the position of the adjusting component, and the adjusting component is installed at the lower right end of the I-beam.

[0011] Furthermore, a plurality of bolts are installed on the upper end of the I-beam, a fixing block is installed on the lower left side of the I-beam, a sliding groove is opened on the lower right side of the fixing block, and the sliding groove is a square cavity. A screw is installed in the middle of the fixing block, and the screw passes through the upper end of the cavity of the sliding groove. A nut is threaded to one end of the screw.

[0012] Furthermore, the adjustment component includes a second fixing block, and a first connecting block is installed on the lower left side of the second fixing block. The first connecting block has a socket in the middle for the extension and retraction of the connecting rod, and the socket is a square groove.

[0013] Furthermore, the middle part of the connecting block one is provided with a sliding groove two, and the sliding groove two is connected to the insertion hole. The front end of the connecting block one is provided with a plurality of positioning vertical grooves for limiting the locking component.

[0014] Furthermore, the locking assembly includes a slide rod for pulling the arc-shaped plate in conjunction with the positioning hole, and the slide rod slides left and right in the groove cavity of the second slide groove. A connecting block two is installed at the front end of the slide rod, and a plurality of vertical blocks for engaging with the positioning vertical groove are provided at the rear end of the connecting block two. A pull ring for pulling the slide rod is installed at the front end of the connecting block two.

[0015] Furthermore, a washer and a spring are sleeved at the rear end of the slide rod, with the washer positioned at the front end of the spring. A threaded hole is machined at the rear end of the slide rod, and a retaining plate for limiting the spring is installed at the rear end of the slide rod.

Detailed Implementation

[0026] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0027] Please see Figures 1-5 This utility model provides a building HVAC pipe installation bracket, including two clamping structures 100 for clamping HVAC pipes. The two clamping structures 100 are arranged symmetrically from left to right to clamp the HVAC pipes when they are close to each other. Each clamping structure 100 includes an arc-shaped plate 110. An anti-slip pad 111 is fixedly installed on the inner wall of the arc-shaped plate 110, and a connecting rod 112 is fixedly installed on the outer wall of the arc-shaped plate 110. The connecting rod 112 is a square rod with a positioning hole 113 in the middle. The square connecting rod 112 facilitates the limiting of the arc-shaped plate 110.

[0028] The upper end of the clamping structure 100 is equipped with a fixing structure 200 for limiting the two clamping structures 100. The fixing structure 200 includes an adjusting component 220 for limiting the right clamping structure 100. The fixing structure 200 includes an I-beam 210 for limiting the adjusting component 220. The adjusting component 220 is welded to the lower right end of the I-beam 210. Multiple bolts 211 are installed on the upper end of the I-beam 210 to fix the I-beam 210 in the installation position.

[0029] A fixing block 212 is fixedly welded to the lower left side of the I-beam 210. A sliding groove 213 is provided at the lower right side of the fixing block 212. The sliding groove 213 is a square cavity. The connecting rod 112 slides in the cavity of the sliding groove 213. When the upper end of the connecting rod 112 abuts against the upper end of the cavity of the sliding groove 213, the arc plate 110 will not shift when the connecting rod 112 is fixed. A screw 214 is installed in the middle of the fixing block 212, and the screw 214 passes through the upper end of the groove of the slide 213. One end of the screw 214 is threaded with a nut 215. When clamping HVAC pipes of different diameters, the nut 215 is unscrewed from the rear end of the screw 214, and the screw 214 is removed from the fixing block 212. Then, the connecting rod 112 on one side of the arc plate 110 is removed from the slide 213. When installing the arc plate 110 of the appropriate size, the connecting rod 112 is placed on the upper end of the groove of the slide 213. Then, the screw 214 is passed through the groove of the slide 213 and the positioning hole 113, and the nut 215 is tightened on the rear end of the screw 214, so that the left end 310 of the I-beam 210 is fixed. When clamping HVAC pipes, only the right clamping structure 100 needs to be adjusted to move.

[0030] The left end of the adjusting assembly 220 is equipped with a locking assembly 230 for locking the position of the right clamping structure 100. The adjusting assembly 220 includes a second fixing block 221, and a first connecting block 222 is fixedly installed on the lower left side of the second fixing block 221. The middle of the first connecting block 222 has an insertion hole 223 for the extension and retraction of the connecting rod 112. The insertion hole 223 is a square cavity, and the connecting rod 112 installed on the right arc plate 110 extends and retracts within the cavity of the insertion hole 223, so that when the right arc plate 110 moves away from the left arc plate 110, the HVAC pipe is placed in the middle of the two arc plates 110, and when the right arc plate 110 moves closer to the left arc plate 110, the two arc plates 110 clamp the HVAC pipe. The middle part of the connecting block 222 is provided with a sliding groove 224, and the sliding groove 224 is connected to the insertion hole 223. The groove cavity of the sliding groove 224 and the groove cavity of the positioning hole 113 are at the same horizontal height. The front end of the connecting block 222 is provided with multiple positioning vertical grooves 225 for limiting the locking component 230.

[0031] The locking assembly 230 includes a slide rod 231 for pulling the arc plate 110 in conjunction with the positioning hole 113, and the slide rod 231 slides left and right within the cavity of the second slide groove 224. After the connecting rod 112 at one end of the right arc plate 110 is inserted into the insertion hole 223, the slide rod 231 passes through the second slide groove 224 and approaches the connecting rod 112 in the cavity of the insertion hole 223. Finally, the slide rod 231 passes through the positioning hole 113 and the second slide groove 224 at the rear end of the first connecting block 222. By passing through the positioning hole 113, the slide rod 231 can simultaneously adjust the distance between the two arc plates 110 when it moves left and right. The front end of the slide rod 231 is fixedly installed with the second connecting block 232, and the rear end of the second connecting block 232 is fixedly provided with multiple vertical blocks 233 for engaging with the positioning vertical groove 225.

[0032] When the vertical block 233 is inserted into the positioning vertical groove 225, the connecting block 232 cannot move, thereby fixing the position of the slide rod 231. This prevents the arc plate 110, which is limited by the slide rod 231, from moving left or right. A pull ring 234 for pulling the slide rod 231 is fixedly installed at the front end of the connecting block 232. By pulling the pull ring 234, the distance between the connecting block 232 and the connecting block 222 can be controlled, thereby locking and unlocking the arc plate 110.

[0033] The rear end of the slide rod 231 is fitted with a washer 236 and a spring 237, with the washer 236 positioned at the front end of the spring 237. Both the washer 236 and the spring 237 are located at the rear end of the connecting block 222. The rear end of the slide rod 231 is machined with a threaded hole 235. A retaining plate 238 for limiting the spring 237 is installed at the rear end of the slide rod 231. A bolt 239 for fixing the retaining plate 238 in conjunction with the threaded hole 235 is installed in the middle of the retaining plate 238. The bolt 239 and the threaded hole 235 are threaded together. After the bolt 239 is screwed into the threaded hole 235, the retaining plate 238 is fixed at the rear end of the slide rod 231, causing the spring 237 to push the retaining plate 238, thereby giving the connecting block 232 a backward pulling force, so that the vertical block 233 is always engaged with the positioning vertical groove 225.

[0034] When fixing the HVAC pipe, by pulling the pull ring 234, the connecting block 232 moves away from the connecting block 1 222, and the vertical block 233 moves away from the positioning vertical groove 225. Pulling the pull ring 234 to the right causes the sliding rod 231 to move the arc plate 110 to the right. Then, the HVAC pipe is placed in the middle of the two arc plates 110. Pulling the pull ring 234 and moving the sliding rod 231 to the left causes the right arc plate 110 to move closer to the left arc plate 110. Finally, after clamping the HVAC pipe, pushing the pull ring 234 backward causes the vertical block 233 at the rear end of the connecting block 232 and the positioning vertical groove 225 at the front end of the connecting block 1 222 to be locked together. Under the push of the spring 237 on the baffle 238, the vertical block 233 is not easy to disengage from the cavity of the positioning vertical groove 225, so that the two arc plates 110 firmly clamp the HVAC pipe.

[0035] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
