[0038] The core of the present invention is to provide a longitudinal connection device, which can improve the storage efficiency of the storage space and improve the temperature control effect of different temperature zones.

[0039] Please refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the structure of the longitudinal connection device provided by the present invention;

[0041] Figure 5 A top view of the longitudinal connecting device provided by the present invention; Figure 6 This is a bottom view of the longitudinal connecting device provided by the present invention.

[0042] The present application provides a longitudinal connection device, which mainly includes an upper connection plate, a lower connection plate, a sealing panel 2-18 and a connection wall panel 2-5.

[0043] The upper connecting plate is used to connect the connecting plate or the top plate of the compartment above, and the lower connecting plate is used to connect the connecting plate or the bottom plate of the compartment below. The load-bearing structure 2-17 (i.e., the load-bearing column) is arranged vertically, and the upper end is connected to the upper connecting plate, and the lower end is connected to the lower connecting plate, and the load-bearing structure 2-17 divides the space between the upper connecting plate and the lower connecting plate into two left and right parts.

[0044] The connecting wall panels 2-5 are provided with transverse ventilation holes 2-15. The two connecting wall panels 2-5 are arranged transversely opposite to each other, respectively located on the left and right sides of the load-bearing structure 2-17, and located between the upper connecting plate and the lower connecting plate.

[0045] The sealing panel 2-18 is disposed between the upper connecting plate and the lower connecting plate, and is vertically connected to the connecting wall plate 2-5 to form a box-like structure.

[0046] The bracket formed by the upper connecting plate, the lower connecting plate (located in the upper and lower directions respectively), the sealing panel 2-18 (located in the front and back), the connecting wall panel 2-5 (located in the left and right) and the load-bearing structure 2-17 is a whole of two ventilation spaces for longitudinal ventilation. The upper connecting plate is provided with an air inlet connecting the ventilation space with the space above it, and the lower connecting plate is provided with an air outlet connecting the space below it with the ventilation space. The connecting wall panel 2-5 and the load-bearing structure 2-17 are connected by a number of horizontal fixed structures 2-8.

[0047] It should be noted that the vertical direction in this application refers to Figure 1 and Figure 2 The up and down direction, horizontal refers to Figure 1 and Figure 2 The left and right directions in the text refer to Figure 1 and Figure 2 The front-to-back direction is the direction perpendicular to the drawing surface. The connecting wall plate 2-5 is a structure extending vertically, and the two supporting balance beams 2-2 are both extended in the horizontal direction, and the two are arranged in the front-to-back direction.

[0048] It should be noted that the upper connecting plate and the lower connecting plate can be an ordinary single plate, or a composite plate group structure, specifically a box-shaped structure that can be used to form two connecting wall panels 2-5 on the opposite side and two sealing panels 2-18 on the other opposite side.

[0049] In the present application, the role of the sealing panel 2-18 is to form a cover for the load-bearing structure 2-17 to prevent air from leaking to the outside through the gap between the front and rear ends of the load-bearing structure 2-17 and the connecting wall panel 2-5.

[0050] The lower connecting plate is used to connect the upper connecting plate of another longitudinal connecting device to form a longitudinal series connection. In the series connection state, a plurality of upper connecting plates and lower connecting plates are in a stable connection state and can withstand pressure and tension from above and below.

[0051] The load-bearing structure 2-17 (i.e., the load-bearing column) includes a longitudinal structure connecting the upper connecting plate and the lower connecting plate, and also includes a middle structure located between the two connecting wall panels 2-5 and used to divide this part of the space into two parts. A fixed structure 2-8 is arranged on the middle structure to realize the connection between the load-bearing structure 2-17 and the connecting wall panels 2-5.

[0052] In the longitudinal connecting device provided by the present application, the upper connecting plate is provided with an air inlet connected to the upper space, so that airflow or refrigerant can be formed to enter from the upper part of the longitudinal connecting device; the lower connecting plate is provided with an air outlet connected to the lower space and the ventilation space, so that the airflow or refrigerant can pass from the lower connecting plate to a longitudinal connecting device at the lower part; the air inlet and the air outlet need to maintain a large area to avoid the formation of vortices, turbulence, insufficient air fluidity, insufficient air pressure and other problems in the air flow, so as to avoid frosting.

[0053] The connecting wall plate 2-5 is provided with ventilation holes 2-15 for connecting the lateral space, so that airflow or refrigerant can pass through the ventilation holes 2-15 on the connecting wall plate 2-5 to the storage space on the side.

[0054] The present application utilizes a longitudinal connecting device that plays a supporting role to conduct the airflow, which can conveniently guide the refrigerant gas into the air inlet position of the guide connecting plate device, and conduct it to the storage spaces at different positions below and on the sides respectively. The refrigerant gas received by the lower storage space is the refrigerant gas that has not passed through other storage spaces, so as to facilitate the direct transmission of cold air through the guide connecting plate device, thereby improving the refrigeration effect of the refrigerant gas in the lower storage space.

[0055] On the basis of the above-mentioned embodiment, a movable damper 2-4 is provided at the ventilation hole 2-15, and the damper 2-4 is connected to the controller. The ventilation opening area of ​​the ventilation hole 2-15 is smaller than the flow cross-sectional area of ​​a single ventilation space.

[0056] Taking into account that the storage spaces in different directions have different demands for refrigeration gas, separate control of different areas is required, and a damper 2-4 is set on the connecting wall panel 2-5. The damper 2-4 is rotatable or movable. When it is rotated or moved to different positions, the ventilation holes 2-15 on the connecting wall panel 2-5 can be opened and closed. The damper 2-4 is connected to the controller. The controller can be manually controlled, or uniformly controlled by a computer, or a sensor is set in the storage structure. The temperature of different positions measured by the sensor is transmitted to the controller. The controller controls the damper 2-4 according to the pre-set temperature of the corresponding storage space and the current temperature, to realize the opening and closing conversion of the vents, thereby changing the ventilation conditions of different storage spaces to change the actual temperature.

[0057] The ventilation opening area of ​​the ventilation hole 2-15 is smaller than the flow cross-sectional area of ​​a single ventilation space, and the single ventilation space is composed of the connecting wall plate 2-5, the load-bearing structure 2-17 and the sealing panels 2-18 on both sides. Its flow cross-sectional area is calculated according to the cross-sectional area of ​​the air inlet from top to bottom. The flow cross-sectional area needs to be larger than the area of ​​the ventilation hole 2-15, or even larger than 2 times the ventilation opening area, so as to avoid that after opening a single ventilation hole 2-15, the longitudinal ventilation pressure is too low, resulting in low ventilation efficiency of multiple longitudinal connection devices connected vertically, and losing or reducing the cooling capacity or energy transmission function.

[0058] On the basis of the above-mentioned embodiment, the upper edge of the damper 2-4 is rotatably connected to the connecting wall plate 2-5 via the rotating rod 2-3, and the rotating rod 2-3 is connected to the controller via a switch.

[0059] Specifically, since the state of the rotation operation is relatively obvious and open or closed has a strong recognition, the switch can be a manual mechanical switch, or a control logic module in a controller, and the switch is also connected to the controller.

[0060] Another advantage of controlling the operation of the dampers 2-4 through a controller is that the structure of the mechanical part is relatively simple and easy to implement.

[0061] On the basis of any one of the above embodiments, the upper connecting plate includes: a guide bridge 2-1 and a supporting balance beam 2-2, and the lower connecting plate includes: a balance groove 2-9 and a guide groove 2-10.

[0062] The guide bridge 2-1 extends longitudinally, with its lower part lower than the supporting balance beam 2-2, and connected to the load-bearing structure 2-17;

[0063] The supporting balance beam 2-2 is connected to the guiding bridge 2-1, and the two supporting balance beams 2-2 are respectively connected to the front end and the rear end of the guiding bridge 2-1, and the supporting balance beams 2-2 extend to both sides in the transverse direction.

[0064] The balance groove 2-9 is used to be plugged with the supporting balance beam 2-2 of the longitudinal connecting device located below in the horizontal direction. The two balance grooves 2-9 are respectively connected to the front end and the rear end of the guide groove 2-10.

[0065] The guide groove 2-10 is connected to the load-bearing structure 2-17 and is used to be plugged into the guide bridge 2-1 of the longitudinal connecting device located below in the horizontal direction.

[0066] Specifically, the support balance beam 2-2 extends to both sides in the horizontal direction. Figure 2 In the perspective of Figure 2 The balance groove 2-9 is also extended from the guide groove 2-10 to the left and right sides. Figure 2 Extensions on the left and right sides of the .

[0067] It should be noted that the guide bridge 2-1 is along Figure 2 The two supporting balance beams 2-2 are respectively connected to the front and rear ends of the guide bridge 2-1 to form an I-shaped structure, and the gaps on both sides are the air inlets provided on the upper connecting plate;

[0068] Correspondingly, the guide grooves 2-10 are along Figure 2 The two balancing grooves 2-9 are respectively connected to the front and rear ends of the guide groove 2-10, and also form an I-shaped structure. The notch structures on both sides are the air outlets set by the lower connecting plate.

[0069] Please refer to Figure 1 The guide bridge 2-1 is vertically connected to the supporting balance beam 2-2, and the balance groove 2-9 is vertically connected to the guide groove 2-10. In addition, the guide bridge 2-1 is physically connected from front to back, and the supporting balance beam 2-2 is hollow between the front and rear ends to form a ventilation space.

[0070] The vertical setting is easier to process and manufacture, and the two are set perpendicular to each other. When the guide bridge 2-1 and the supporting balance beam 2-2 are inserted into the groove formed by the balance groove 2-9 and the guide groove 2-10 as a whole, it is easier to determine the direction and angle, and the connection effect is more intuitive and easy to control.

[0071] Optionally, the guide bridge 2-1 and the supporting balance beam 2-2 may also have other angles or structures, but the balance groove 2-9 and the guide groove 2-10 are required to meet the same structure so as to form a plug-in or snap-in connection state.

[0072] On the basis of the above-mentioned embodiment, there is a first gap 2-16 between the supporting balance beam 2-2 and the adjacent connecting wall panels 2-5 on both sides. The first gap 2-16 is larger than the wall thickness of the balance groove 2-9. When the supporting balance beam 2-2 is inserted into the balance groove 2-9, the first gap 2-16 disappears and a closed structure is formed.

[0073] The wall thickness of the balancing groove 2-9 is the same as the size of the first gap 2-16, which helps to keep the upper and lower connection structures in the same size state after the plug-in is completed. The wall thickness of the balancing groove 2-9 is greater than the size of the first gap 2-16, which helps to facilitate the plug-in.

[0074] It should be noted that the above-mentioned first gap 2-16 being larger than the wall thickness of the balancing groove 2-9 means that the first gap 2-16 is slightly larger than the wall thickness of the balancing groove 2-9, that is, it can satisfy the gap between the balancing groove 2-9 supporting the balancing beam 2-2 and the connecting wall panel 2-5, and there will be no large gap left in the plugged-in state. For example, the first gap 2-16 is larger than the wall thickness of the balancing groove 2-9 by about 0.1 mm. When it is not working and stationary, it is a relatively closed structure and may cause air leakage. When cold air starts to flow into it, the water vapor in the air will condense to make the gap in the middle disappear, thereby playing an insulating role.

[0075] On the basis of the above-mentioned embodiment, a support frame 2-11 and an anti-jump frame 2-12 are provided at the lower part of the connecting wall panel 2-5, and a horizontal slot is provided between the support frame 2-11 and the anti-jump frame 2-12 for clamping a transversely arranged transverse plate.

[0076] On the basis of the above embodiment, two connecting wall panels 2-5 are arranged opposite to each other, and two bracket assemblies are arranged between them. The two bracket assemblies are respectively located at the two ends of the length direction of the connecting wall panels and the two are connected to form two transversely arranged ventilation spaces.

[0077] On the basis of the above-mentioned embodiment, the supporting balance beam 2-2 may be located inside the projection surface of the connecting wall panel 2-5, and the balance groove 2-9 may be located inside the projection surface of the connecting wall panel 2-5 to which it is connected.

[0078] In a specific embodiment, when the two longitudinal connecting devices located at the upper and lower positions are connected, that is, the guide groove 2-10 of the upper longitudinal connecting device is plugged into the guide bridge 2-1 of the lower longitudinal connecting device, and at the same time, the balance groove 2-9 of the upper longitudinal connecting device is plugged into the support balance beam 2-2 of the lower longitudinal connecting device, the upper and lower surfaces of the connected components form an I-shaped vertical load-bearing structure.

[0079] Please refer to Figure 1 Among them, the guide bridge 2-1, the guide groove 2-10, the supporting balance beam 2-2 and the balance groove 2-9 are combined with the load-bearing structure 2-17 to form an I-shaped vertical load-bearing structure.

[0080] Optionally, the guide bridge 2-1 extends longitudinally, and its upper portion protrudes from the supporting balance beam 2-2, and its lower portion protrudes downward from the supporting balance beam 2-2, and is connected to form a load-bearing structure 2-17 and a sealing panel 2-18, the thickness of the sealing panel 2-18 is the same as the thickness of the supporting balance beam 2-2, and the gap between the supporting balance beam 2-2 and the sealing panel 2-18 is greater than the wall thickness of the balance groove 2-9. When the supporting balance beam 2-2 is inserted into the balance groove 2-9, the above gap disappears to form a closed structure.

[0081] Optionally, when the guide bridge 2-1, the supporting balance beam 2-2, the load-bearing structure 2-17, the sealing panel 2-18 and the connecting wall panel 2-5 are connected, a polyhedron structure is formed, and the gas flows in a direction in the polyhedron structure.

[0082] The present invention can make it possible to form a multi-temperature zone storage structure and provide structural improvements for the individual control of different storage spaces. It can achieve the effect of zoned isolation, refrigeration and temperature regulation, realize multiple controllable independent intervals, and improve shelf utilization.

[0083] The longitudinal connection device of the present invention forms a support structure with an air flow channel by establishing a combined structure, and establishes two unconnected ventilation ducts mainly for vertical ventilation up and down in the middle of the support structure. The ventilation ducts output wind to the air outlets on both sides to adjust the temperature or connect to more ventilation ducts downward.

[0084] Since the dampers 2-4 in the present application are structures controlled by a controller, they have a certain position state and can limit swinging in the horizontal direction, so that the storage structure formed by the longitudinal connecting device can be used not only in a warehouse in a static state, but also in a warehouse in transportation.

[0085] In the actual setting process, the setting of the ventilation duct must be consistent with the air flow being poured vertically downward from the top of the guide bridge 2-1 position, so as to minimize the resistance encountered by the air during the flow.

[0086] In a specific embodiment, the guide bridge 2-1 is horizontally inserted into the guide groove 2-10 to form a cross-shaped structure with the supporting balance beam 2-2 so as to be inserted into the cross groove formed by the balance groove 2-9 and the guide groove 2-10.

[0087] The supporting balance beam 2-2 is used to receive the forces from above and below, and can also play an anti-shake role during the overall transportation of the equipment.

[0088] The rotating rod 2-3 is used to control the opening and closing of the damper 2-4.

[0089] The damper 2-4 opens and closes the ventilation hole according to the control of the rotating rod 2-3.

[0090] The connecting wall panel 2-5 is provided with a ventilation wall eye 2-6 and a fixing bolt 2-7. The fixing bolt 2-7 is inserted into the ventilation eye 2-6 to fix the connecting wall panel 2-5 and the fixing structure 2-8.

[0091] The fixed structure 2-8 is located at the lower part of the supporting balance beam 2-2 and at the upper part of the guide groove 2-10. The fixed structure 2-8 is fixedly connected to the fixing bolt 2-7 and can be used to strengthen the overall structure to avoid shaking.

[0092] The support frame 2-11 is a horizontal support on the connecting wall plate 2-5, and forms a groove structure with the anti-jump frame 2-12, which can prevent the cross plate from jumping during transportation and causing the cross plate to fall.

[0093] The first gap 2-16 is a space located between the supporting balance beam 2-2 and the connecting wall panel 2-5 in the transverse direction, and is used for the insertion of the balance groove 2-9.

[0094] The above-mentioned load-bearing structure 2-17 can be a load-bearing column, which is a structure used to bear force in the longitudinal connecting device structure, and is used to form a ventilation duct that passes through from top to bottom with the connecting wall panel 2-5 and the fixed structure 2-8.

[0095] In addition to the main structure of the longitudinal connecting device provided in the above embodiments, the present invention also provides a storage structure including the longitudinal connecting device disclosed in the above embodiments. For the structure of other parts of the storage structure, please refer to the prior art and will not be described in detail herein.

[0096] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0097] The above is a detailed introduction to the storage structure and longitudinal connection device provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
