Description

Technical Field

[0001] The utility model relates to a cabinet air conditioner lower baffle installation positioning structure, belonging to the cabinet air conditioner technical field. Background Art

[0002] The cabinet air conditioner is a device used to adjust the ambient temperature, relative humidity, and flow rate of the air inside the base station cabinet to ensure that the communication equipment can work in a stable temperature and humidity environment. Due to the limited space of the base station, the existing cabinet air conditioners are mostly integrated with the internal and external units, and the inner and outer sides are separated by parts such as partitions and lower baffles to ensure that the parts on the inner and outer parts can be relatively independent and cooperate with each other to jointly maintain the normal operation of the cabinet air conditioner. Since the partition has the function of collecting the condensed water of the inner evaporator and the parts need to be easy to assemble, the partition and the lower baffle are two separate parts in most cabinet air conditioners.

[0003] See also Figure 1 and Figure 3 The conventional scheme of the prior art includes an outer frame, which includes at least a left side plate, a right side plate and a bottom plate. The bottom plate is arranged horizontally, and the left side plate and the right side plate are fixedly arranged at both ends of the length direction of the bottom plate. The area between the left side plate and the right side plate is fixedly provided with a partition and a lower baffle for separating the inner area and the outer area of ​​the cabinet air conditioner. The lower part of the partition has a condensation water collection box with an opening facing upward. The lower baffle is installed between the partition and the bottom plate. The bottom plate is provided with a bottom plate bending edge at the edge of the side corresponding to the lower baffle. The bottom plate bending edge is arranged vertically. A positioning bracket is welded and fixed on the upper surface of the bottom plate in the area close to the bottom plate bending edge. The positioning bracket and the bottom plate bending edge cooperate to form a positioning structure in the front and rear direction of the lower baffle. The lower baffle is fixed to the bottom plate after positioning is completed. The above-mentioned positioning bracket is a separate part and needs to be welded to the bottom plate at the same time. Its main disadvantages are: first, it increases the material cost and manufacturing cost of the whole machine, affecting the efficiency of the production line; another point is that the positioning bracket is prone to position deviation when welded to the bottom plate, affecting the positioning accuracy of the lower baffle. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a cabinet air conditioner lower baffle installation positioning structure, which can improve the positioning accuracy of the lower baffle during installation, and at the same time can reduce the use of parts and improve production efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cabinet air conditioner lower baffle installation and positioning structure, including an outer frame, the outer frame at least includes a left plate, a right plate and a bottom plate, the bottom plate is horizontally arranged, the left plate and the right plate are fixedly arranged at both ends of the length direction of the bottom plate, the area between the left plate and the right plate is fixedly provided with a partition and a lower baffle for separating the inner area and the outer area of ​​the cabinet air conditioner, the lower part of the partition has a condensate collection box with an opening facing upward, the lower baffle is installed between the partition and the bottom plate, the bottom plate is provided with a bottom plate bending edge at the edge portion of the side corresponding to the lower baffle, the bottom plate bending edge is vertically arranged, and the bottom plate A convex bulge is provided in an area near the bending edge of the bottom plate (which can be achieved by conventional stamping technology) and is an integral structure with the bottom plate body. The convex bulge is protruding relative to the upper surface of the bottom plate, and the side of the convex bulge facing the bending edge of the bottom plate has a convex side opening, and the outer end surface of the convex side opening is parallel to the bending edge of the bottom plate and intersects with the upper surface of the bottom plate at right angles. The outer end surface of the convex side opening cooperates with the bending edge of the bottom plate to form a positioning structure in the front and rear directions of the lower baffle plate, and the upper edge of the lower baffle plate has a lower baffle plate bending edge, which overlaps the upper end surface of the condensate collection box, and the lower part of the lower baffle plate is fixed to the bending edge of the bottom plate by bolts.

[0006] It is further preferred that a clearance fit is formed between the outer end surface of the convex hull side opening and the outer surface of the lower baffle.

[0007] It is further preferred that: a plurality of convex hulls are arranged at intervals along the length direction of the bottom plate, and the outer end surfaces of the side openings of the convex hulls are located in the same vertical plane.

[0008] The beneficial effects of the utility model are as follows: the convex bulge and its side opening structure are integrally formed with the bottom plate, and no further processing is required, which can effectively ensure the consistency of positioning. At the same time, the positioning structure does not need to be welded separately to form a positioning bracket, which can effectively save material costs and processing costs, and is more economical. Since the positioning structure is a convex bulge with an opening located on the bottom plate plane, the convex bulge also has a drainage function. When rainwater from the outside enters the cabinet, it can also be discharged from the opening of the convex bulge and other water leakage holes on the bottom plate, thereby optimizing the drainage effect of the cabinet air conditioner.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 2 to 8As shown, the utility model includes an outer frame, which includes at least a left side plate 1, a right side plate 2 and a bottom plate 5. The bottom plate 5 is horizontally arranged, and the left side plate 1 and the right side plate 2 are fixedly arranged at both ends of the length direction of the bottom plate 5. The area between the left side plate 1 and the right side plate 2 is fixedly provided with a partition 3 and a lower baffle 4 for separating the inner area and the outer area of ​​the cabinet air conditioner. The lower part of the partition 3 has a condensate collection box 31 with an opening facing upward, and the lower baffle 4 is installed between the partition 3 and the bottom plate 5, that is, the lower baffle 4 cooperates with the partition 3 to separate the inner area and the outer area of ​​the cabinet air conditioner. The bottom plate 5 is provided with a bottom plate bending edge 51 at the edge portion of the side corresponding to the lower baffle 4, and the bottom plate bending edge 51 is vertically arranged; the bottom plate 5 is provided with a convex hull 52 (generally stamping can be used) which is an integral structure with the bottom plate 1 body in the area close to the bottom plate bending edge 51, and the convex hull 52 is provided with a protrusion 52 protruding relative to the upper surface of the bottom plate 5. The side of the convex bulge 52 facing the bottom plate bending edge 51 has a convex side opening 53, the outer end face of the convex side opening 53 is parallel to the bottom plate bending edge 51 and intersects with the upper surface of the bottom plate 5 at right angles, and the outer end face of the convex side opening 53 cooperates with the bottom plate bending edge 51 to form a positioning structure for the lower baffle plate 4 in the front-to-back direction, which is equivalent to the lower end of the lower baffle plate 4 being inserted into the interval area between the outer end face of the convex side opening 53 and the bottom plate bending edge 51 to achieve the front-to-back positioning, and the upper edge of the lower baffle plate 4 has a lower baffle plate bending edge 41, which overlaps the upper end face of the condensate collection box 31 (which is equivalent to achieving the positioning of the lower baffle plate 4 in the upper and lower directions). In specific implementation, after the lower baffle plate 4 is initially installed and positioned using the above-mentioned positioning structure, the lower part of the lower baffle plate 4 is finally fixed to the bottom plate bending edge 51 by bolts, and the number of bolts can be flexibly set according to actual conditions.

[0020] In order to achieve a better positioning effect, a plurality of convex bumps 52 can be arranged at intervals along the length direction of the bottom plate 5, and the outer end faces of the convex bump side openings 53 are located in the same vertical plane. The number of convex bumps 52 is generally 3 to 5. The convex bumps 52 and the side opening structure are integrated with the bottom plate 5 and are directly formed by stamping. They do not need to be welded to the bottom plate 5 separately. On the one hand, the position accuracy of the convex bumps 52 is guaranteed, and on the other hand, the number of parts and the manufacturing cost can be reduced, and the positioning accuracy of the lower baffle 4 during installation is also guaranteed.

[0021] In addition, after the lower portion of the lower baffle 4 is fixed to the bottom plate bent edge 51 by bolt connection, a clearance fit is generally formed between the outer end surface of the convex hull side opening 53 and the outer surface of the lower baffle 4. Since the convex hull side opening 53 is connected to the inner cavity of the convex hull 52, when rainwater from the outside enters the cabinet, it can also be discharged from the convex hull side opening 53, thereby optimizing and improving the drainage effect of the cabinet air conditioner. This drainage structure can be used in conjunction with other conventional water leakage hole structures.

[0022] Parts of the present invention that are not described in detail may be implemented with reference to the prior art. For example, the partition 3 may generally be fixed to the outer frame of the cabinet air conditioner by riveting. The structure of the condensate collection box 31 is compatible with the evaporator and is used to collect condensate from the evaporator inside the cabinet air conditioner.
