[0036] This utility model provides a convenient installation device for the housing of a refrigeration core. Figures 1 to 4 An embodiment of the refrigeration core convenient housing installation device provided by this utility model.

[0037] Please refer to the following: Figures 1 to 4The convenient installation device for the refrigeration core includes a housing body 1 and an unlocking component 2. The housing body 1 includes two first connecting plates 101, two second connecting plates 102, and two third connecting plates 103. The front and rear ends of the two first connecting plates 101 are each provided with a connector 106 that inserts into the second connecting plate 102. The top and bottom of the two second connecting plates 102 are each provided with a connecting component 104 that engages with the third connecting plate 103 to prevent separation of the third connecting plate 103 from the second connecting plate 102. The two second connecting plates 102... Each of the three third connecting plates 103 is threaded with a screw 105 connected to the first connecting plate 101 to restrict the separation of the first connecting plate 101 and the second connecting plate 102. The unlocking component 2 is installed on the two third connecting plates 103 and has a travel distance from the third connecting plate 103 toward the second connecting plate 102. The travel distance has an unlocking position and a reset position. In the unlocking position, the unlocking component 2 is inserted into the second connecting plate 102 and abuts against the connecting component 104. In the reset position, the unlocking component 2 is away from the second connecting plate 102.

[0038] Take out the two first connecting plates 101. Since both the front and rear ends of the first connecting plates 101 are equipped with connectors 106, insert these connectors 106 into the corresponding positions of the two second connecting plates 102 to initially connect the first connecting plates 101 and 102 together. At this point, the relative positions of the first and second connecting plates are initially fixed. However, to further solidify the connection, screw connectors 105 are needed. Screw connectors 105 are threaded onto the two second connecting plates 102, and are threaded into the first connecting plates 101. By rotating the screw connectors 105, they are continuously screwed into the first connecting plates 101, thereby tightly fixing the first connecting plates 101 and 102 together and preventing separation. Connecting components 104 are provided at the top and bottom of the two second connecting plates 102. At this time, the two third connecting plates 103 are placed at the top and bottom of the second connecting plate 102 respectively, so that the third connecting plate 103 corresponds to the connecting component 104. Due to the function of the connecting component 104, the third connecting plate 103 will be snapped into the second connecting plate 102, thereby realizing the connection between the third connecting plate 103 and the second connecting plate 102, while restricting the separation of the third connecting plate 103 and the second connecting plate 102.

[0039] When it is necessary to disassemble the casing, operate the unlocking component 2 to move it from the reset position toward the direction of the second connecting plate 102. When the unlocking component 2 moves to the unlock position, the unlocking component 2 will be inserted into the second connecting plate 102 and abut against the connecting component 104. At this time, the connecting component 104 is resisted by the unlocking component 2, and its locking restriction on the third connecting plate 103 is released. With the unlocking component 2 in the unlocked position, since the locking restriction between the third connecting plate 103 and the second connecting plate 102 has been released, the third connecting plate 103 can be separated from the second connecting plate 102, completing the disassembly of the third connecting plate 103. After the third connecting plate 103 is disassembled, the screw connector 105 is unscrewed from the first connecting plate 101 and the second connecting plate 102, releasing the threaded connection restriction between the first connecting plate 101 and the second connecting plate 102. Then, the plug connector 106 on the first connecting plate 101 is pulled out from the second connecting plate 102, realizing the separation of the first connecting plate 101 and the second connecting plate 102. Thus, the disassembly of the entire housing device is completed.

[0040] Therefore, in the technical solution provided by this utility model, the top and bottom of the two second connecting plates 102 are provided with connecting components 104 that are snapped into the third connecting plate 103 to restrict the separation of the third connecting plate 103 from the second connecting plate 102. The unlocking component 2 is installed on the two third connecting plates 103 and has a travel distance from the third connecting plate 103 toward the second connecting plate 102. It has an unlocking position and a reset position on the travel distance. In the unlocking position, the unlocking component 2 is inserted into the second connecting plate 102 and abuts against the connecting component 104. In the reset position, the unlocking component 2 is away from the second connecting plate 102. Through the design of the plug 106, the connecting component 104 and the screw 105, quick assembly is achieved. The unlocking component 2 makes disassembly easy and efficient. Its structure is stable, and the multi-mode connection and fixation ensures tight connection between components. It also has good versatility and high maintainability, and is suitable for a variety of refrigeration cores, making maintenance and parts replacement convenient.

[0041] The connecting component 104 initially connects the second connecting plate 102 and the third connecting plate 103, preventing them from separating arbitrarily. Many structures can achieve this purpose. Specifically, in this embodiment of the present invention, the connecting component 104 includes a connecting block 1041, two limiting blocks 1042, and two first elastic members 1043. The connecting block 1041 is installed in the second connecting plate 102 and inserted into the third connecting plate 103. The two limiting blocks 1042 are slidably installed in the connecting block 1041 and pass through the left and right sides of the connecting block 1041, respectively, and are inserted into the third connecting plate 103. One end of each of the two first elastic members 1043 is installed in the connecting block 1041, and the other end is installed in the limiting block 1042.

[0042] When the connecting block 1041 is inserted into the third connecting plate 103, two limiting blocks 1042 are slidably installed inside the connecting block 1041, and each limiting block 1042 is connected to a first elastic element 1043. Under the elastic action of the first elastic element 1043, the limiting block 1042 is subjected to an outward elastic force. When the connecting block 1041 is inserted into the third connecting plate 103 to a certain depth, the limiting blocks 1042, pushed by the first elastic element 1043, penetrate through the left and right sides of the connecting block 1041 respectively, and are inserted into the corresponding limiting holes or limiting grooves in the third connecting plate 103. At this time, the limiting blocks 1042 lock the third connecting plate 103, preventing it from separating from the second connecting plate 102 in the horizontal direction, thereby achieving a stable connection between the second connecting plate 102 and the third connecting plate 103.

[0043] During installation, simply insert the connecting block 1041 into the third connecting plate 103, and the limiting block 1042 will automatically slide out and insert into the third connecting plate 103 under the action of the first elastic element 1043. No additional operating steps or tools are required, greatly improving installation efficiency. Moreover, this structural design not only facilitates manufacturing and processing but also reduces the failure rate of components and improves the reliability of the entire connecting assembly 104.

[0044] Furthermore, the limiting block 1042 has an inclined surface on the side away from the second connecting plate 102.

[0045] As the connecting block 1041 is inserted into the third connecting plate 103, the limiting block 1042 begins to function. Because the limiting block 1042 has a slope on the side away from the second connecting plate 102, during the insertion of the third connecting plate 103, the inner wall of the third connecting plate 103 contacts the slope of the limiting block 1042. As the insertion depth increases, the compressive force exerted by the inner wall of the third connecting plate 103 on the slope is decomposed into a force perpendicular to the slope and a force along the slope that causes the limiting block 1042 to slide inwards towards the connecting block 1041. Under the action of this component force, the limiting block 1042 overcomes the elastic force of the first elastic element 1043 and slides inwards towards the connecting block 1041. The sloped design of the limiting block 1042 eliminates the need for precise manual alignment of the limiting block 1042 with the limiting holes or grooves on the third connecting plate 103 during installation. Once the connecting block 1041 is inserted into the third connecting plate 103, the limiting block 1042 can automatically slide into the appropriate position under the guidance of the inclined surface, achieving rapid locking.

[0046] Furthermore, the unlocking component 2 includes a movable plate 201, a second elastic element 202, and an unlocking block 203. The movable plate 201 is slidably installed in the third connecting plate 103. One end of the second elastic element 202 is installed in the third connecting plate 103, and the other end is installed in the movable plate 201. The unlocking block 203 is disposed on the side of the movable plate 201 facing the second connecting plate 102, so as to move from the reset position to the unlock position to hold the limiting block 1042 to fully enter the connecting block 1041.

[0047] When the housing needs to be disassembled, the movable plate 201 is pushed towards the second connecting plate 102, and the movable plate 201 slides within the third connecting plate 103, overcoming the elastic force of the second elastic member 202. As the movable plate 201 slides, the unlocking block 203, located on the side of the movable plate 201 facing the second connecting plate 102, also moves closer to the second connecting plate 102. When the movable plate 201 slides to the unlocked position, the unlocking block 203 inserts into the second connecting plate 102 and abuts against the limiting block 1042. The unlocking block 203 continues to apply pressure, causing the limiting block 1042 to overcome the elastic force of the first elastic member 1043 and fully enter the connecting block 1041. At this time, the limiting block 1042 disengages from the limiting hole or limiting groove of the third connecting plate 103, releasing the clamping restriction on the third connecting plate 103.

[0048] By simply pushing the movable plate 201, the unlocking block 203 can abut against the limiting block 1042, thereby unlocking and separating the third connecting plate 103 from the second connecting plate 102. This one-button unlocking method is simple and easy to understand, requiring no complicated tools or tedious steps. Even non-professionals can easily disassemble and assemble the casing, greatly improving work efficiency.

[0049] While connecting the first connecting plate 101 and the second connecting plate 102 through the connector 106, it is necessary not only to complete the positioning work but also to perform preliminary limitation. Specifically, in the technical solution of this utility model, each of the two first connecting plates 101 has a first connecting groove on the side facing the second connecting plate 102 for the connector 106 to slide and connect. The first connecting plate 101 has a second connecting groove for the connector 106 to insert into, so as to limit the separation of the second connecting plate 102 from the first connecting plate 101.

[0050] The positioning function of the first connecting groove and the limiting function of the second connecting groove combine to provide dual connection protection for the first connecting plate 101 and the second connecting plate 102. The first connecting groove ensures accurate positioning during installation, while the second connecting groove effectively restricts separation after installation, making the connection more stable. When the casing is subjected to external impact or vibration, it can better maintain the connection state of the first connecting plate 101 and the second connecting plate 102, ensuring the stability of the overall casing structure.

[0051] Furthermore, the number of screw connectors 105 is at least four. The arrangement of at least four screw connectors 105 ensures that the first connecting plate 101 and the second connecting plate 102 are subjected to uniform force during connection. With multiple screw connectors 105 distributed at different positions on the connecting plates, the forces exerted by each screw connector 105 on the connecting plate are balanced during tightening, avoiding deformation of the connecting plate or loose connection due to single-point force or uneven force distribution.

[0052] The electronic components inside the casing generate heat during operation, which needs to be released to the outside of the casing in a timely manner. Specifically, in the technical solution of this utility model, ventilation holes are provided on both second connecting plates 102 to release the heat inside the casing. With ventilation holes on the two second connecting plates 102, the heat generated inside the casing is gradually transferred to the second connecting plates 102 through heat conduction and convection. Hot air flows to the outside of the casing through the ventilation holes, while cool air from the outside enters the casing through the ventilation holes, forming natural air convection, thereby continuously expelling the heat from inside the casing and maintaining the internal temperature of the casing within a relatively stable range.

[0053] Furthermore, a fan 4 is installed within one of the ventilation holes to accelerate airflow. During the initial operation of the casing, the ventilation holes allow hot air inside to rise naturally and be expelled through the holes, while cool air from the outside enters, creating natural convection. Simultaneously, the fan 4 installed within the ventilation hole begins operation. The blades of the fan 4 rotate at high speed, rapidly drawing the hot air from inside the casing and expelling it to the outside. The powerful suction of the fan 4 accelerates the airflow, allowing hot air inside the casing to be expelled more quickly, while more cool air is drawn into the casing. This combination of natural convection and forced convection by the fan 4 significantly improves the airflow efficiency inside the casing, enabling faster removal of heat generated by electronic components and maintaining the internal temperature of the casing within a suitable range.

[0054] Furthermore, both second connecting plates 102 are equipped with dustproof mesh 3 to block dust. When the electronic components inside the casing generate heat during operation, hot air is exhausted through the ventilation holes, and cool air enters, forming air convection. In this process, the dustproof mesh 3 plays a crucial role, blocking dust particles from the outside air and preventing dust from entering the casing. Although air can circulate normally through the dustproof mesh 3, dust is intercepted, thus ensuring a clean working environment for the electronic components inside the casing.

[0055] In one embodiment, each of the two second connecting plates 102 is provided with a positioning post and a positioning pin on opposite sides to limit the installation position of the movement.

[0056] In another embodiment, each of the two third connecting plates 103 is provided with a positioning post and a positioning pin on opposite sides to limit the installation position of the movement.

[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
