DETAILED DESCRIPTION

[0021] In the description of the present utility model, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present utility model. The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0022] See also Figures 1 to 7, the present utility model preferably provides a technical solution: a detachable coil group structure, comprising: a coil body 10, a mounting frame body annularly distributed on the peripheral side of the coil body 10, the mounting frame body being used for the self-supporting installation of the coil body 10 and serving as a connection bridge between the coil body 10 and the outer frame body 9; the mounting frame body includes a mounting frame 1, two sets of telescopic column assemblies 3 arranged at the upper and lower parts of the mounting frame 1, and two limit members 2 arranged on the opposite surfaces of the two sets of telescopic column assemblies 3, and the two limit members 2 are symmetrically distributed. Each limit member 2 is composed of a vertical portion 203 at the end, and a concave portion 201 and a convex portion 202 which are alternately arranged in sequence and have a corrugated structure; the mounting frame 1 has an inverted "U" shape structure and is used for the mounting frame body to be inserted into the coil body 10 from top to bottom for pre-assembly; it further includes a cam transmission assembly 4 arranged on the mounting frame 1, the cam transmission assembly 4 acts on the two limit members 2 and is used for their closing or separating. When the two limit members 2 are closed, it is used for the limit locking of the coil body 10. When the two limit members 2 are separated, it is used for the quick installation and removal of the coil body 10 and the mounting frame body.

[0023] In this application, the provided mounting frame body, while supporting the coil body 10, also serves as a connection bridge between the coil body 10 and the outer frame body 9. Here, the outer frame body 9 is the cylindrical structure of the heat exchanger. Specifically, the mounting frame body is preferably four groups, as Figure 1 , 2 shown. Each group of mounting frame bodies includes telescopic column assemblies 3 respectively arranged at the upper and lower parts of the mounting frame 1, and two limit members 2 arranged on the opposite surfaces of the two sets of telescopic column assemblies 3. Here, the two limit members 2 can serve as the limit support structure of the coil body 10. Specifically, as Figure 5 shown, each limit member 2 includes a vertical portion 203 at the end, and a concave portion 201 and a convex portion 202 which are alternately arranged in sequence and have a corrugated structure. When the cam transmission assembly 4 acts on the convex portions 202 where the two limit members 2 are located, at this time, the two limit members 2 can be closed. Then, the two concave portions 201 where the limit members 2 are located are closed and wrap the pipe wall of the coil body 10, thereby realizing the limit locking process of the coil body 10, as Figure 1 , 2 and 3 shown. When the two limit members 2 lose the action of the cam transmission assembly 4, the two limit members 2 can be separated under the action of the telescopic column assemblies 3 and thus realize the quick installation and removal of the coil body 10 and the mounting frame body;

[0024] It is known that the mounting frame 1 has an inverted "U" shape structure, as Figure 4 , 5As shown, when the two stoppers 2 are in a separated state, the installation frame 1 where the installation frame is located can be inserted from top to bottom into the coil body 10 to achieve pre-assembly of the coil body 10, and then the cam transmission assembly 4 is driven so that when the two stoppers 2 are closed, the recesses 201 where the two stoppers 2 are located can wrap the tube wall of the coil body 10 one by one, thereby achieving the limit locking process of the coil body 10;

[0025] The utility model realizes the closing and separation process of the two limit members 2 through the effective cooperation of the telescopic column assembly 3 and the cam transmission assembly 4. When the two limit members 2 are in the separated state, it is convenient for the quick installation and removal of the coil body 10 and the mounting frame. When the two limit members 2 are in the closed state, the limit locking of the coil body 10 is further realized. At this time, the mounting frame can serve as a connecting bridge between the coil body 10 and the outer frame 9. Figure 7 As shown, the design is simple to assemble and has a stable structure, providing a quick-install and quick-disinstall installation method for the coil body 10 and the outer frame 9, thereby facilitating subsequent maintenance while ensuring the stability of the coil body 10 during operation.

[0026] Furthermore, each group of telescopic column assemblies 3 includes two groups of telescopic rods 301, which are respectively fixed on the opposite sides of the two vertical portions 203, and one end of each group of telescopic rods 301 away from the vertical portion 203 passes through a first through hole opened on the side wall of the mounting frame 1 and is fixed with a connecting strip 302; it also includes a spring 303 sleeved on the outer wall of each telescopic rod 301, and the two ends of the spring 303 are respectively fixed to the opposite surfaces of the vertical portion 203 and the mounting frame 1.

[0027] Here, if Figure 3 , 4 As shown in FIG. 5 , each group of two telescopic rods 301 has one end fixed to the corresponding vertical portion 203 and the other end fixed with a connecting strip 302, which cooperates with the action of the spring 303 to achieve resetting, i.e., the separation process, when the two limit members 2 lose the action of the cam transmission assembly 4.

[0028] Furthermore, the cam transmission assembly 4 includes two transmission rods 401, which are arranged on the inner top of the installation frame 1 and placed on the outside of the two limit members 2, and a plurality of cam bodies 402 fixed on each transmission rod 401; and also includes an engaging transmission assembly 5 arranged on the top of the installation frame 1, and the engaging transmission assembly 5 is used to drive the two transmission rods 401 to rotate.

[0029] like Figure 3 , 5 As shown, it is worth noting that the cam body 402 is an elliptical structure. Figure 7As shown, the cam body 402 on the transmission rod 401 corresponds to the convex part 202 and the vertical part 203 where the stopper 2 is located. When the convex end of the cam body 402 acts on the corresponding convex part 202 and makes the concave parts 201 where the two stoppers 2 are located close, as shown in FIG. Figure 5 As shown, the two limit members 2 can be in a closed state. At this time, the two recessed portions 201 where the limit members 2 are located can wrap the tube wall of the coil body 10. At the same time, the vertical portions 203 are moved closer to each other under the action of the corresponding cam body 402, thereby stretching the spring 303 where the telescopic column assembly 3 is located. When the cam body 402 rotates and the convex end where the cam body 402 is located is separated from the convex portion 202 and the vertical portion 203, the limit member 2 is reset under the action of the spring 303.

[0030] Furthermore, the meshing transmission assembly 5 includes a connecting rod 501 rotatably connected to the top of the mounting frame 1, and a first transmission tooth 502 fixed on the connecting rod 501; it also includes two connecting shafts rotatably connected to the top of the mounting frame 1, and second transmission teeth 503 fixed at one end of the two connecting shafts are meshed with the first transmission teeth 502, and the other ends thereof respectively pass downward through second through holes opened at the top of the mounting frame 1 and are fixed to the two transmission rods 401; it also includes a driving assembly 6 arranged at the top of the mounting frame 1, and the driving assembly 6 is used for the operation and locking of the connecting rod 501.

[0031] like Figure 4 As shown, the first transmission tooth 502 where the meshing transmission component 5 is located is meshed with the two second transmission teeth 503, and the two second transmission teeth 503 are fixed to the two transmission rods 401. Therefore, by rotating the connecting rod 501 connected to the first transmission tooth 502, the transmission rod 401 where the cam transmission component 4 is located and the cam body 402 on the transmission rod 401 can switch positions, thereby realizing the closing and separation process of the two limit members 2.

[0032] Furthermore, the driving assembly 6 includes a first connecting frame 601 fixed to the top of the mounting frame 1, and a mounting rod 602 vertically rotatably connected to the middle part of the first connecting frame 601, and one end of the mounting rod 602 passes through a third through hole opened on the first connecting frame 601 and is fixed to the connecting rod 501, and the other end thereof extends upward and is fixed with a handle 603; a transmission disk 604 is arranged on the mounting rod 602, and a card slot 605 is annularly opened on the outer periphery of the transmission disk 604; it also includes a second connecting frame 606 fixed to the first connecting frame 601, and a connecting rod 607 is slidably installed inside the second connecting frame 606, and a card block 608 arranged at the outer end of the connecting rod 607 is adapted to engage with the single card slot 605; it also includes a shifting post 609 fixed on the top of the connecting rod 607.

[0033] Here Figure 1 , 6As shown, the handle 603 is connected to the connecting rod 501 through the mounting rod 602, so when the handle 603 is rotated, the meshing transmission assembly 5 can be driven to operate, and the connecting rod 607, the fixed lever 609 at one end of which can be adapted to engage with the slot 605 provided on the outer periphery of the transmission disk 604, and the transmission disk 604 rotates with the mounting rod 602. Therefore, when the handle 603 is driven, it drives the cam body 402 to switch positions while realizing the position movement of the transmission disk 604, and the position locking of the cam body 402 can be realized by the engagement of the block 608 with the slot 605. Here, the slot 605 is preferably four groups, so that the single rotation angle of the transmission disk 604 is 90°, thereby realizing the staggered operation of the cam body 402 contacting and disengaging with the protrusion 202.

[0034] Furthermore, the side wall of the installation frame 1 is also provided with a mounting member 7, which includes two brackets 701, which are vertically and symmetrically distributed at the upper and lower parts of the installation frame 1; and a mounting groove 702 provided on each bracket 701; and also includes a mounting hole 703 provided on each bracket 701. The mounting groove 702 and the mounting hole 703 provided here can connect the mounting member 7 to the outer frame 9 through existing parts, and the connection state is as shown in FIG. Figure 7 shown.

[0035] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection. There are many ways of detachable installation, for example, it can be through the method of plug-in and snap-fit, or through the method of bolt connection, etc.

Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
