[0025] like Figures 1 to 4 As shown, a return water heat exchange device which is easy to install and maintain comprises a return water heat exchanger body 1 and a fixing plate 2. The return water heat exchanger body 1 is placed on the upper surface of the fixing plate 2. A card slot is provided on the upper surface of the fixing plate 2. A positioning mechanism 3 for limiting the position of the return water heat exchanger body 1 at the upper end of the fixing plate 2 is installed inside the card slot of the fixing plate 2. Two groups of grooves are provided on the upper surface of the positioning mechanism 3. A limiting mechanism 5 is installed inside the two groups of grooves of the positioning mechanism 3. Specifically, by starting the positioning mechanism 3, the left and right sides of the top of the positioning mechanism 3 are attached to the left and right sides of the return water heat exchanger body 1, so that the return water heat exchanger body 1 is installed on the upper surface of the fixing plate 2 by card connection, so that it is convenient for subsequent users to install and disassemble the return water heat exchanger body 1, thereby reducing the time spent by subsequent users in repairing the return water heat exchanger body 1.
[0026] like Figures 1 to 3 As shown, the positioning mechanism 3 includes two groups of sliders 302 and a connecting plate 304. The connecting plate 304 is installed inside the card slot of the fixed plate 2. The front and rear sides of the card slot of the fixed plate 2 are provided with grooves. The two groups of sliders 302 are respectively slidably connected inside the two groups of grooves of the fixed plate 2. The adjacent sides of the two groups of sliders 302 are installed with racks 303. The upper surface of the connecting plate 304 is provided with a through hole. The through hole of the connecting plate 304 is rotatably connected with a rotating rod 305. The outer surface of the rotating rod 305 is installed with a gear 306. The external teeth of the gear 306 are meshed and connected inside the teeth of the two groups of racks 303. The upper surfaces of the two groups of sliders 302 are installed with limit plates 301. The adjacent sides of the two groups of limit plates 301 are respectively attached to the left and right sides of the return water heat exchanger body 1.
[0027] Specifically, after the return water heat exchanger body 1 is placed on the upper surface of the fixed plate 2, the gear 306 is driven to drive the two sets of racks 303 to move by rotating the rotating rod 305, and then the two sets of limit plates 301 are synchronously driven to move during the movement by the two sets of racks 303, and the adjacent sides of the two sets of limit plates 301 are respectively attached to the left and right sides of the return water heat exchanger body 1, so that the return water heat exchanger body 1 is installed on the upper surface of the fixed plate 2 by snap-fitting, so that the subsequent users can install and disassemble the return water heat exchanger body 1, thereby reducing the time spent by the subsequent users in repairing the return water heat exchanger body 1.
[0028] At the same time, by setting the positioning mechanism 3 inside the card slot and at the lower end of the fixing plate 2, the fixing plate 2 shields part of the positioning mechanism 3, thereby avoiding the positioning mechanism 3 from being exposed during use as much as possible, thereby improving the aesthetics of the device during use.
[0029] like Figure 1 and Figure 2 As shown, two groups of support blocks 4 are installed on the lower surface of the fixed plate 2, and the positions of the two groups of support blocks 4 are symmetrically distributed on the left and right sides of the lower end of the fixed plate 2; specifically, the two groups of support blocks 4 are installed on the lower surface of the fixed plate 2, so that when the fixed plate 2 is placed on the ground, it relies on the two groups of support blocks 4 to break contact with the ground, thereby minimizing the impact of the lower end of the rotating rod 305 and the ground when the user moves the device, causing damage to the positioning mechanism 3.
[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the limiting mechanism 5 includes two groups of connecting blocks 501, the upper surfaces of the two groups of limiting plates 301 are provided with card slots, the two groups of connecting blocks 501 are rotatably connected to the inside of the card slots of the two groups of limiting plates 301, the upper surfaces of the two groups of connecting blocks 501 are provided with L-shaped fixing plates 502, the upper surfaces of the two groups of connecting blocks 501 are provided with through holes, the inner wall tops of the two groups of L-shaped fixing plates 502 are installed with electric telescopic rods 503, and the output ends of the two groups of electric telescopic rods 503 are respectively passed through the two groups of connecting blocks 50 1 is provided with a top plate 504; specifically, when the return water heat exchanger body 1 is placed on the upper surface of the fixing plate 2, the two sets of electric telescopic rods 503 are started to push the two sets of top plates 504 to move, and the lower surfaces of the two sets of top plates 504 are both in contact with the upper surface of the return water heat exchanger body 1, so that the two sets of top plates 504 limit the forward and backward movement position of the return water heat exchanger body 1 on the upper surface of the positioning mechanism 3, thereby improving the stability of the return water heat exchanger body 1 during use.
[0031] At the same time, when the user is disassembling and maintaining the return water heat exchanger body 1, the user pushes the connecting block 501 to drive the two groups of top plates 504 to flip out of the disassembly path of the return water heat exchanger body 1, so that subsequent users do not need to start the two groups of electric telescopic rods 503 to adjust the positions of the two groups of top plates 504 during the process of disassembling and moving the return water heat exchanger body 1, thereby minimizing the influence of the limiting mechanism 5 on the subsequent users' disassembly and maintenance of the return water heat exchanger body 1 when limiting the upper end position of the fixed plate 2.
[0032] like Figure 1 and Figure 4 As shown, the upper surfaces of the two groups of limit plates 301 are provided with through holes, and the through holes of the two groups of limit plates 301 are rotatably connected to the limit rods 6, and the lower surfaces of the two groups of limit rods 6 are respectively attached to the upper surfaces of the two groups of connection blocks 501; specifically, when the lower surfaces of the two groups of top plates 504 are attached to the upper surface of the return water heat exchanger body 1, the two groups of limit rods 6 are rotated to make the lower surfaces of the two groups of limit rods 6 respectively attached to the upper surfaces of the two groups of connection blocks 501, so that the two groups of limit rods 6 limit the rotational position of the two groups of connection blocks 501 inside the slots of the limit plates 301, thereby minimizing the upward rotation of the two groups of connection blocks 501 inside the slots of the two groups of limit plates 301 during use.
[0033] like Figure 1 and Figure 4 As shown, limiting blocks 7 are installed on opposite sides of the two groups of top plates 504, and the opposite sides of the two groups of limiting blocks 7 are respectively attached to the adjacent sides of the two groups of limiting plates 301; specifically, the opposite sides of the two groups of limiting blocks 7 are respectively attached to the adjacent sides of the two groups of limiting plates 301, so that the two groups of limiting blocks 7 limit the downward rotation path of the two groups of connecting blocks 501 in the slots of the two groups of limiting plates 301, thereby improving the stability of the limiting mechanism 5 during use.
[0034] In summary: by rotating the rotating rod 305, the gear 306 drives the two sets of racks 303 to move, and then the two sets of racks 303 synchronously drive the two sets of limit plates 301 to move during the movement, and the adjacent sides of the two sets of limit plates 301 are respectively attached to the left and right sides of the return water heat exchanger body 1, so that the return water heat exchanger body 1 is installed on the upper surface of the fixed plate 2 by a snap-on manner, so as to facilitate the subsequent installation and disassembly of the return water heat exchanger body 1 by the user; by starting the two sets of electric telescopic rods 503 to push the two sets of top plates 504 to move, the lower surfaces of the two sets of top plates 504 are both in contact with the upper surface of the return water heat exchanger body 1, so that the two sets of top plates 504 limit the forward and backward movement position of the return water heat exchanger body 1 on the upper surface of the positioning mechanism 3.
[0035] At the same time, by pushing the connecting block 501, the two sets of top plates 504 are driven to flip out of the disassembly path of the return water heat exchanger body 1, so that subsequent users do not need to start the two sets of electric telescopic rods 503 to adjust the positions of the two sets of top plates 504 during the process of disassembling and moving the return water heat exchanger body 1, thereby minimizing the impact of the limit mechanism 5 on the subsequent users' disassembly and maintenance of the return water heat exchanger body 1 when limiting the upper end position of the return water heat exchanger body 1 at the fixed plate 2; by rotating the two sets of limit rods 6, the lower surfaces of the two sets of limit rods 6 are respectively attached to the upper surfaces of the two sets of connecting blocks 501, so that the two sets of limit rods 6 limit the rotational position of the two sets of connecting blocks 501 inside the slots of the limit plates 301, thereby minimizing the upward rotation of the two sets of connecting blocks 501 inside the slots of the two sets of limit plates 301 during use.
