Description

Technical Field

[0001] This utility model relates to the technical field of cooling and heating unit equipment, and in particular to a connecting frame for a modular integrated cooling and heating unit. Background Technology

[0002] Modular integrated cooling and heating units are modern devices that integrate multiple functions such as refrigeration, heating, and ventilation. Internally, they typically consist of multiple functional components, including compressor modules, heat exchanger modules, fan modules, and electrical control systems. To securely assemble these individual modules into a single unit, a robust connecting frame must be used as its load-bearing and fixing skeleton.

[0003] In practical applications, existing connecting frames mostly rely on traditional threaded fasteners such as bolts and nuts for assembly. This connection method requires a large number of fasteners, and various tools such as wrenches are needed to tighten them one by one during installation, resulting in cumbersome on-site installation steps, consuming a lot of manpower and time, and low overall construction efficiency.

[0004] Furthermore, with technological advancements and diversified customer needs, the models and dimensions of core components such as compressors and heat exchangers deployed within the unit often change. The support platforms or shelves inside the existing connecting frame used to house these components are typically fixed at the design stage and cannot be adjusted. This fixed structure results in poor versatility and adaptability of the connecting frame. Once the dimensions of internal components change, the original connecting frame may no longer be suitable, requiring rework or even customization. This significantly limits the flexibility of modular design and increases costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a connecting frame for modular integrated cooling and heating units, which aims to improve the problems of cumbersome and time-consuming installation process and poor equipment adaptability caused by the fixed height of the internal support platform.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connecting frame for a modular integrated cooling and heating unit, comprising: a first connecting plate, a second connecting plate, a third connecting plate, and a sliding frame; as well as a quick-release assembly, an adjustment assembly, and a second fixing plate.

[0007] The quick-release assembly is a built-in rotary drive locking mechanism that includes a connecting block, a threaded block, a sliding block, and a limiting ball; the adjustment assembly is a press-type reset positioning mechanism that includes a limiting block and a spring, and the first connecting plate is provided with an adjustment bracket that cooperates with it.

[0008] Furthermore, the quick-release assembly is disposed between the first connecting plate, the second connecting plate, and the third connecting plate to achieve a fixed connection between the three; the sliding frame is connected to the limiting block in the adjustment assembly through the second fixing plate, and the limiting block slides with the adjustment frame.

[0009] Preferably, the inner wall of the second fixing block in the quick-release assembly is provided with a groove for accommodating the limiting ball.

[0010] Preferably, the adjustment frame on the first connecting plate has a sliding groove and a limiting groove communicating with the sliding groove, and one end of the limiting block in the adjustment assembly has a locking tooth structure that engages with the limiting groove.

[0011] Preferably, the other end of the limiting block is provided with a groove that matches the outer contour of the adjusting frame.

[0012] Preferably, the first fixing plate in the adjusting assembly is connected to the limiting block and disposed between the limiting block and the spring, with one end of the spring abutting against the first fixing plate.

[0013] Preferably, one end of the second fixing plate is fixedly connected to the limiting block, and the other end is fixedly connected to the sliding frame.

[0014] Preferably, the connecting block and the threaded block in the quick-release assembly are coaxially fixedly connected.

[0015] Preferably, the end of the sliding block in the quick-release assembly facing the limiting ball has an inclined surface.

[0016] This utility model has the following beneficial effects: In this invention, by setting up a quick-release component, during operation, only the connecting block needs to be rotated to quickly lock and fix each connecting plate through the linkage of the threaded block, sliding block and limit ball. This solves the problem that the connecting frame in the prior art mostly uses bolt connection, and the installation process is complicated and time-consuming. It achieves the effect of simplifying the installation steps, shortening the installation time and improving the construction efficiency.

[0017] In this invention, by setting an adjustment component consisting of a limit block, a spring, and an adjustment frame, pressing the limit block can drive the sliding frame to adjust its height along the adjustment frame and automatically lock it at the target position. This solves the problem in the prior art that the height of the internal bearing platform of the connecting frame is fixed and cannot flexibly adapt to equipment of different sizes, achieving the effect of tool-free convenient adjustment and improving equipment adaptability and versatility.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 7 This utility model provides a connecting frame for a modular integrated cooling and heating unit, which aims to solve the problems of complex installation, long installation time, fixed height, and poor adaptability of the connecting frame in the prior art. like Figure 1 As shown, the connecting frame for the modular integrated cooling and heating unit includes a first connecting plate 1, a second connecting plate 2, and a third connecting plate 3 that form the main frame of the connecting frame, as well as a sliding frame 7 for horizontally supporting equipment.

[0022] The modular integrated cooling and heating unit's connecting frame also includes a quick-release component 4, an adjustment component 5, and a second fixing plate 6. The quick-release component 4 is located at the connection point of the first connecting plate 1, the second connecting plate 2, and the third connecting plate 3. The adjustment component 5 is used to adjustably connect the sliding frame 7 to the first connecting plate 1.

[0023] Specifically, the quick-release assembly 4 includes a connecting block 401, a first fixing block 402, a second fixing block 403, a limiting ball 404, a sliding block 405, and a threaded block 406. The connecting block 401 and the threaded block 406 are coaxially arranged and fixedly connected. The first fixing block 402 has an internal thread, and the threaded block 406 has an external thread that mates with the internal thread. The sliding block 405 is slidably disposed in the inner cavity of the first fixing block 402 and abuts against one end of the threaded block 406. The other end of the sliding block 405 has an inclined surface for pressing the limiting ball 404. The limiting ball 404 is disposed between the inclined surface of the sliding block 405 and the second fixing block 403. The inner wall of the second fixing block 403 has a groove for accommodating the limiting ball 404.

[0024] An adjusting frame 501 is fixedly connected to the first connecting plate 1. The adjusting frame 501 has a sliding groove extending along its length and multiple limiting grooves communicating with the sliding groove. The adjusting assembly 5 includes a limiting block 502, a first fixing plate 503 and a spring 504. The limiting block 502 is slidably engaged with the adjusting frame 501. One end of the limiting block 502 has a tooth structure that engages with the limiting groove, and the other end has a groove that matches the adjusting frame 501. The spring 504 is disposed between the limiting block 502 and the first connecting plate 1. The first fixing plate 503 is connected to the limiting block 502 and is located between the limiting block 502 and the spring 504. One end of the spring 504 abuts against the first fixing plate 503. The sliding frame 7 is fixedly connected to the limiting block 502 through the second fixing plate 6.

[0025] As a preferred implementation method, refer to Figure 2 and Figure 4 The inner wall of the second fixing block 403 is provided with a groove for stably accommodating the limiting ball 404. This groove ensures that the limiting ball 404 can reliably engage when extruded, thus providing a stronger locking force. (Refer to...) Figure 5 and Figure 6 The adjusting frame 501 has a continuous sliding groove along its vertical direction and multiple limiting grooves that are laterally connected to the sliding groove. The limiting block 502 has a locking tooth structure at one end facing the adjusting frame 501, which can engage with any of the limiting grooves. The other end of the limiting block 502 is provided with a groove that matches the outer contour of the adjusting frame 501 to increase stability in the locked state.

[0026] Reference Figure 7The first fixing plate 503 is fixedly connected to the limiting block 502 and serves as the bearing surface of the spring 504. One end of the spring 504 abuts against the surface of the first fixing plate 503 facing away from the limiting block 502, and the other end of the spring 504 abuts against the first connecting plate 1. The second fixing plate 6 serves as a connector, with one end fixedly connected to the limiting block 502 and the other end fixedly connected to the sliding frame 7, so that the adjustment and locking of the entire sliding frame 7 are accomplished by operating the limiting block 502. The connecting block 401 and the threaded block 406 are coaxially fixedly connected, ensuring direct transmission of the operation. The end of the sliding block 405 facing the limiting ball 404 is provided with one or more inclined surfaces, which are used to convert the axial linear movement of the sliding block 405 into radial extrusion force on the limiting ball 404.

[0027] Working principle: When the connecting frame of the unit is quickly installed, when the first connecting plate 1, the second connecting plate 2 and the third connecting plate 3 need to be spliced, the connecting block 401 in the quick-release assembly 4 is rotated. Since the connecting block 401 is fixedly connected to the threaded block 406, the threaded block 406 rotates synchronously. Through the cooperation of its external thread and the internal thread of the first fixed block 402, the rotational motion is converted into axial linear motion, which in turn pushes the sliding block 405 to slide in the first fixed block 402. The inclined structure of the sliding block 405 will squeeze the limiting ball 404 outward radially, so that the limiting ball 404 is stuck in the groove of the inner wall of the second fixed block 403, thereby generating a strong limiting force on the second fixed block 403 and realizing the quick locking and fixing of the three connecting plates. The height adjustment process is as follows: When the height of the sliding frame 7 needs to be adjusted, press the limiting block 502 in the adjustment component 5. The limiting block 502 moves inward against the elastic force of the spring 504 and simultaneously squeezes the spring 504 through the first fixing plate 503. During this process, the locking tooth structure of the limiting block 502 disengages from the limiting groove of the adjustment frame 501 and enters the sliding groove. At this time, the entire sliding frame 7 connected to the limiting block 502 through the second fixing plate 6 is unlocked and can slide up and down along the sliding groove. When the desired height is reached, release the limiting block 502. Under the action of the spring 504's rebound force, the limiting block 502 automatically resets and drives its locking tooth structure to engage in the nearest limiting groove, thereby completing the stable locking of the sliding frame 7 at the new height.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
