DETAILED DESCRIPTION

[0022] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be further described below with reference to the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0024] Embodiment one: as shown in the present application provides a kind of central heating with expansion tank installation base, including base body 1, base body 1 top two sides are equipped with locking assembly 4, base body 1 bottom central control mechanism 3 is installed, control mechanism 3 top two sides are equipped with positioning mechanism 2; Figure 1 Figure 3

[0025] Control mechanism 3 includes rotating column 31, rotating column 31 outer surface is fixedly connected with fixed frame 35, fixed frame 35 inner side is rotatably connected with linkage rod 34, linkage rod 34 one end is rotatably connected with moving block 33, moving block 33 is slidably connected with the surface of base body 1;

[0026] Positioning mechanism 2 includes moving frame 21, moving frame 21 bottom is fixedly connected with moving block 33, moving frame 21 top two sides are fixedly connected with fixed rod 22, fixed rod 22 top end outer surface is fixedly connected with mounting frame 23, mounting frame 23 middle part is screw-connected with first threaded rod 24, and first threaded rod 24 bottom end is rotatably connected with extrusion pad 25.

[0027] Rotating column 31 bottom end outer surface is fixedly connected with handle 32, moving block 33 is slidably connected with base body 1. One of moving block 33 surface is screw-connected with second threaded rod 36, and second threaded rod 36 bottom end abuts base body 1 top.

[0028] ​​The specific setup and function of this embodiment are described below. After the expansion tank is placed on top of the base body 1, the rotation of the rotating column 31 is used to achieve precise positioning of the expansion tank. When the rotating column 31 rotates, the fixed frame 35 is driven to rotate together through the linkage frame. The rotation of the fixed frame 35 causes the linkage rod 34 to move. The synergistic effect of these two linkage rods 34 causes the moving block 33 to slide along the surface of the base body 1, thereby driving the moving frame 21 to move closer to the side wall of the expansion tank.

[0029] During this process, the two sides of the movable frame 21 clamp and position the sidewalls of the expansion tank. The clamping force is provided by the squeezing force of the two movable frames 21, ensuring the stability and accurate positioning of the expansion tank after placement. At the same time, due to the synchronous movement of the two movable frames 21, they can evenly distribute the pressure applied to the sidewalls of the expansion tank, avoiding tank deformation or inaccurate positioning that may be caused by uneven clamping.

[0030] As the movable frame 21 contacts the side wall of the expansion tank, the mounting frame 23 begins to move along the set track, approaching the top of the expansion tank. When the mounting frame 23 reaches the top, the user can activate the threaded drive mechanism by turning the two first threaded rods 24, pushing the compression pad 25 downwards in the vertical direction. The downward pressing action of the compression pad 25 further increases the clamping force on the top of the expansion tank, ensuring that the top of the tank is firmly positioned.

[0031] This precise positioning and clamping mechanism not only improves the stability and fixation of the expansion tank but also reduces tank displacement or instability caused by external factors during operation. The compression pad 25 plays a crucial role, providing further locking force at the top of the tank to ensure its stability during subsequent operations, preventing potential shifts or displacements and thus improving the overall system's accuracy and safety.

[0032] Example 2: Figure 4 As shown, the locking assembly 4 includes a fixed plate 41, the bottom of which is fixedly connected to the base body 1, and limit holes 42 are formed on both ends of the fixed plate 41. A limit rod 43 is slidably connected inside the limit hole 42, and one end of the limit rod 43 is fixedly connected to the movable frame 21. A movable rod 44 is slidably connected to the middle of the fixed plate 41, and a pressing plate 45 is fixedly connected to one end of the movable rod 44. A spring 46 is provided between the pressing plate 45 and the fixed plate 41, and the spring 46 is sleeved on the outer surface of the movable rod 44.

[0033] The overall effect of this embodiment is that, when placing the expansion tank, the elastic action of the spring 46 first initiates the movement of the compression plate 45. The pre-compression state of the spring 46 effectively pushes the compression plate 45 downward, which not only serves as preliminary positioning but also ensures that the expansion tank does not deviate from its predetermined position during placement. The downward movement of the compression plate 45 drives the movable rod 44 to move together, thereby allowing the compression plate 45 to make close contact with the surface of the expansion tank, further fixing the position of the expansion tank. This preliminary positioning process provides a stable foundation for subsequent precise positioning.

[0034] Next, by rotating the handle 32 at the bottom of the rotating column 31, the linkage rod 34 is driven to control the movement of the moving block 33 under the guidance of the fixed frame 35. As the handle 32 rotates, the linkage rod 34 begins to function, transmitting the rotational force to the moving block 33. Under the action of the linkage rod 34, the moving block 33 begins to slide along the surface of the base body 1 and pushes the moving frame 21 toward the expansion tank.

[0035] To ensure that the moving frame 21 stays on the correct trajectory, the limiting rod 43 plays a crucial role. The limiting rod 43 is designed on the base body 1 and mates with the limiting hole 42. When the moving frame 21 moves, the limiting rod 43 slides within the limiting hole 42. Through this tight fit, the limiting rod 43 effectively restricts the range of motion of the moving frame 21, ensuring that it always moves along a straight track. This design prevents deviation or tilting due to improper operation or external interference, ensuring that the expansion tank remains stable and accurately positioned throughout the entire process.

[0036] The method of use and working principle of this device: After placing the expansion tank on top of the base body 1, the elasticity of the spring 46 pushes the compression plate 45 to move. During this process, the compression plate 45 will drive the movable rod 44 to move together, thereby initially positioning the expansion tank. Then, rotate the handle 32 at the bottom of the rotating column 31. When the rotating column 31 rotates, it will drive the fixed frame 35 to rotate together. When the fixed frame 35 rotates, it will drive the linkage rod 34 to start moving. The two linkage rods 34 will start to apply force to the moving block 33. When the moving block 33 slides on the surface of the base body 1, it will drive the moving block 33 to move. When the movable frame 21 approaches the side wall of the expansion tank, the side wall of the expansion tank can be clamped and positioned by the compression positioning of the two movable frames 21. In addition, as the movable frame 21 contacts the side wall of the expansion tank, the mounting frame 23 will move to the top of the expansion tank. Tightening the two first threaded rods 24 can push the compression pad 25 downward. The compression pad 25 can be used to position the top of the expansion tank, which can further improve the locking effect of the expansion tank. As the movable frame 21 moves, the limiting rod 43 will slide inside the limiting hole 42, thereby ensuring that the movable frame 21 can move linearly when it contacts the expansion tank.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
