[0016] The effect achieved by the above components is that the clamping plate is clamped inside the corresponding slot on the rotating shaft under the elastic force of the second spring on the fixing block.

[0017] Preferably, the other end of the sliding pin is rotatably connected to a support plate.

[0018] The effect achieved by the above components is that after the clamping plate is pulled out from the inside of the slot, the support plate can be rotated to the outside of the assembly block, and at this time, the temporary support of the pulled-out clamping plate can be realized.

[0019] In summary:

[0020] 1. In the present utility model, when the exhaust hood needs to be disassembled, the auxiliary strip can be directly inserted into the inside of the limiting frame, and the clamping frame inside the card slot can be pushed out, facilitating the extraction and disassembly of the assembly block.

[0021] 2. In the present utility model, after adjusting the exhaust air plate to an appropriate angle, the support plate located on the side wall of the assembly block is rotated out.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Referring to Figure 1 as shown, the present utility model provides a technical solution: a spliced exhaust air hood for central air-conditioning engineering installation, including a plurality of assembly blocks 1 and a plurality of exhaust air plates 2. The plurality of assembly blocks 1 are grouped in pairs, and a splicing structure 3 is provided on the surface of the assembly block 1, and an adjustment structure 4 is provided on the surface of the assembly block 1.

[0029] The following specifically describes the specific settings and functions of its splicing structure 3 and adjustment structure 4.

[0030] Referring to Figures 1 - 4As shown in the figure, in this embodiment: The splicing structure 3 includes a rotating shaft 33 rotatably connected inside the assembly block 1. The rotating shaft 33 is fixedly connected to the end side of the exhaust air plate 2. A positioning pin 32 is fixedly connected to the surface of the assembly block 1. A positioning hole 34 is formed in the lower surface of the assembly block 1. The size of the positioning pin 32 is adapted to the size of the positioning hole 34. A limiting frame 35 is fixedly connected to the surface of the assembly block 1. The limiting frame 35 is of a "U" - shaped structure. A clamping frame 36 is slidably connected inside the limiting frame 35. The upper side of the clamping frame 36 is of a right - angled trapezoid structure. A plurality of card slots 39 are formed in the surface of the assembly block 1. First, the positioning pin 32 is sleeved inside the positioning hole 34, which can realize the rapid positioning work between adjacent assembly blocks 1. During the process of moving the assembly block 1, the upper assembly block 1 will abut against the lower surface of the clamping frame 36 at the lower position. At this time, the driving work of the clamping frame 36 inside the limiting frame 35 can be realized. When the two assembly blocks 1 move to a position where they are in contact with each other, the clamping frame 36 is stuck on the inner wall of the corresponding card slot 39, which can realize the fixing work between the moved assembly blocks 1. A first spring 37 is fixedly connected between the clamping frame 36 and the limiting frame 35. The clamping frame 36 is stuck on the inner wall of the corresponding card slot 39 under the action of the elastic force of the first spring 37.

[0031] An elastic pad 38 is adhesively bonded to the surface of the assembly block 1. By providing the elastic pad 38, the tightness of the adjacent assembly blocks 1 when they are abutted and installed against each other is improved. An auxiliary strip 31 is slidably inserted through the inside of a plurality of limiting frames 35. When the exhaust hood needs to be disassembled, the auxiliary strip 31 can be directly inserted into the inside of the limiting frame 35, which can realize the work of pushing out the clamping frame 36 inside the card slot 39, facilitating the extraction and disassembly work of the assembly block 1.

[0032] Refer to Figures 1 - 2 and Figures 4 - 5 As shown in the figure, specifically, the adjusting structure 4 includes a fixed block 41 fixedly connected to the surface of the assembly block 1. A sliding pin 44 is slidably connected inside the fixed block 41. The other end of the sliding pin 44 is fixedly connected to a clamping plate 43. A plurality of slots 42 are evenly formed in the side wall of the rotating shaft 33. The size of the slots 42 is adapted to the size of the clamping plate 43. The clamping plate 43 is stuck inside the corresponding slot 42 on the rotating shaft 33, which can realize the fixing work of the rotated rotating shaft 33.

[0033] A second spring 46 is sleeved on the surface of the sliding pin 44. The two ends of the second spring 46 are respectively fixedly connected to the clamping plate 43 and the fixed block 41. The clamping plate 43 is stuck inside the corresponding slot 42 on the rotating shaft 33 under the action of the elastic force of the second spring 46 on the fixed block 41. The other end of the sliding pin 44 is rotatably connected to a support plate 45. After the clamping plate 43 is pulled out from the inside of the slot 42, the support plate 45 can be rotated to the outside of the assembly block 1. At this time, the temporary support work of the pulled - out clamping plate 43 can be realized.

[0034] Working principle: When splicing the exhaust hood is required, first, the positioning pin 32 is sleeved inside the positioning hole 34, which can achieve the rapid positioning of adjacent assembly blocks 1. During the process of moving the assembly block 1, the upper assembly block 1 will abut against the lower part of the position clamping frame 36. At this time, the driving of the clamping frame 36 inside the limiting frame 35 can be achieved. When the two assembly blocks 1 move to the position where they are in contact with each other, the clamping frame 36 will be stuck on the inner wall of the corresponding clamping groove 39 under the elastic force of the first spring 37, which can achieve the fixation of the assembly blocks 1 after movement. By setting the elastic pad 38, the tightness of the adjacent assembly blocks 1 when they are abutted and installed against each other is improved. Assembling the adjacent assembly blocks 1 in sequence can achieve the installation of the exhaust hood. When the exhaust hood needs to be disassembled, the auxiliary strip 31 can be directly inserted into the inside of the limiting frame 35, which can achieve the work of pushing out the clamping frame 36 inside the clamping groove 39, facilitating the extraction and disassembly of the assembly block 1. By setting the splicing structure 3, the flexible assembly and disassembly of the exhaust hood are facilitated, and the flexible carrying and transportation of the exhaust hood are facilitated, which improves the service performance of the exhaust hood to a certain extent.

[0035] Pull out the sliding pin 44 inside the moving fixed block 41. After pulling out the clamping plate 43 from the inside of the slot 42, the support plate 45 can be rotated to the outside of the assembly block 1. At this time, the temporary support of the pulled-out clamping plate 43 can be achieved. At this time, the use angle of the exhaust plate 2 can be adjusted by rotating the rotating shaft 33 inside the assembly block 1. After adjusting the exhaust plate 2 to an appropriate angle, the support plate 45 located on the side wall of the assembly block 1 is rotated out. At this time, the clamping plate 43 will be stuck inside the corresponding slot 42 of the rotating shaft 33 under the elastic force of the second spring 46 on the fixed block 41, which can achieve the fixation of the rotated rotating shaft 33, thus facilitating the fixation of the rotated exhaust plate 2. By setting the adjustment structure 4, the flexible adjustment of the position of the rotated exhaust plate 2 is facilitated, and the service performance of the exhaust plate 2 is further improved.
