Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerated containers, and more specifically, it relates to an improvement in the structure of a water leakage device for refrigerated containers. Background Art

[0003] The structure of the water leakage device is as Figure 1 shown, and mainly includes a main body member of the water leakage device. A water leakage cavity is formed inside it, and a plug 950 is arranged above the water leakage cavity to block the water leakage device through the plug.

[0004] The plug is inserted into the top position of the water leakage cavity and protrudes from the main body member 940 of the water leakage device.

[0005] The existing refrigerated container floor generally adopts a T-shaped floor structure. During installation, the above-mentioned water leakage device is assembled in the gap between two adjacent plates of the T-shaped floor, and the water leakage device is folded. To prevent the plug from being lost, a steel wire rope is connected to the top of the plug. One end of the steel wire rope is connected to the T-shaped floor, and the other end is connected to the plug to prevent the plug from being lost.

[0052] In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0053] In some embodiments of the present application, a water leakage device is provided, including:

[0054] A main body member, in which a receiving portion 140 is formed, and a clamping and limiting portion 141 is formed on the inner wall of the receiving portion 140;

[0055] In some embodiments, the main body member includes a first member 110, a second member 120, and a third member 130 that are connected in sequence from top to bottom.

[0056] The first member 110 is a first aluminum cylinder shell, and the second member 120 is an extended aluminum tube connected to the first aluminum cylinder shell.

[0057] The third member 130 is a water outlet nozzle connected below the second member 120.

[0058] The receiving portion 140 is a water leakage cavity formed in the first member 110, the second member 120, and the third member 130.

[0059] The plug body 200 is embedded in the receiving portion 140 and is detachable relative to the main body component;

[0060] An opening is formed at the top of the accommodating portion 140 to facilitate the plug body 200 to be removed from or inserted into the opening.

[0061] The plug body 200 is a rubber plug, which is elastic and can be deformed when subjected to force.

[0062] During assembly, it is inserted into the top area of ​​the receiving portion 140 through the opening to seal the receiving portion 140 .

[0063] The plug body 200 is embedded inside the main component and will not protrude from the main component, thus realizing the embedded setting of the plug body 200 so that it will not protrude from the top surface of the flat floor, thereby enabling it to adapt to the flat floor structure.

[0064] A flexible connector 300 is arranged in the receiving portion 140 and has a stretching end 310, wherein the stretching end 310 passes through the plug body 200 and extends out from the main body member;

[0065] And the connecting end 320 is arranged at an end opposite to the stretching end 310 .

[0066] In some embodiments, the flexible connector 300 is a steel wire rope, and the steel wire rope is built into the accommodating portion 140 .

[0067] One end thereof forms a stretching end 310 , and the other end forms a connecting end 320 . The connecting end 320 is arranged opposite to the stretching end 310 and is located inside the accommodating portion 140 .

[0068] The stretching end 310 passes through the plug body 200 and extends out from the main component to the outside, mainly to facilitate the user to perform a stretching operation by grabbing the stretching end 310 .

[0069] In order to ensure that the steel wire rope can pass through, a through hole is opened on the plug body 200, and the inner diameter of the through hole is adapted to the outer diameter of the steel wire rope to ensure that the steel wire rope can pass through the plug body 200 smoothly.

[0070] The first limiting member 400 is connected to the flexible connecting member 300 and is used to prevent the flexible connecting member 300 from falling off from the plug body 200 .

[0071] In some embodiments, the first limiting member 400 is a first aluminum seal fixedly connected to the steel wire rope, and the inner diameter of the through hole on the plug body 200 is smaller than the outer diameter of the first aluminum seal.

[0072] When pulling the steel wire rope, the steel wire rope can move relative to the plug body 200, driving the first limiting member 400 to move. When the first limiting member 400 reaches the position of the through hole, it is limited, thereby also realizing the limitation of the flexible connecting member 300 and preventing it from separating from the plug body 200 and coming out of the plug body 200.

[0073] At the same time, when pulling the steel wire rope from the stretching end 310, the steel wire rope first moves relative to the plug body 200. When the first limiting member 400 is located at the plug body 200, the first limiting member 400 will abut against the plug body 200. Continuing to apply a force to the stretching end 310 of the flexible connecting member 300 will drive the plug body 200 to come out of the accommodating portion 140 under the action of the first limiting member 400, realizing the opening of the plug body 200.

[0074] The guiding and limiting assembly 500 is arranged in the accommodating portion 140 and connected to the connecting end 320, and is used to guide the flexible connecting member 300 when it drives the plug body 200 to move and be clamped in the clamping and limiting portion 141 when the movement reaches the position to prevent the plug body 200 from coming out.

[0075] The guiding and limiting assembly 500 can play a guiding role for the plug body 200 when the flexible connecting member 300 pulls the plug body 200 to move and open.

[0076] Specifically, when the flexible connecting member 300 and the first limiting member 400 drive the plug body 200 to move, the guiding and limiting assembly 500 located in the accommodating portion 140 can slide along the accommodating portion 140 to guide its movement.

[0077] As the plug body 200 is continuously pulled outwards, it will drive the guiding and limiting assembly 500 to move outwards continuously. When the guiding and limiting assembly 500 moves to the position of the clamping and limiting portion 141 on the accommodating portion 140, it is clamped and limited by the clamping and limiting portion 141, so that it cannot continue to slide, thereby realizing the limitation of the flexible connecting member 300, and further realizing the limitation of the plug body 200, effectively avoiding the problem that the plug body 200 falls and is lost from the accommodating portion 140;

[0078] And after the plug body 200 is opened, the flexible connecting member 300 built in the accommodating portion 140 and limited by the limiting and guiding assembly is always connected to it, effectively avoiding the loss of the plug body 200.

[0079] In addition, the flexible connecting member 300 is built in the main body member. When it is installed on the flat floor, it can effectively prevent the goods from pulling and breaking and causing the problem of the loss of the plug body 200, thereby avoiding the problem that the refrigeration effect is poor due to the connection between the refrigerated container and the external space caused by the loss of the plug body 200.

[0080] The built-in wire rope can reduce external fixing points and eliminate the manual drilling and installation steps, making its installation more convenient.

[0081] In some embodiments of the present application, a first embedding cavity is provided in the first member 110. The first embedding cavity includes a conical cavity 111 and a circular cavity 112 communicating with the conical cavity 111. The plug body 200 is a conical plug, and a part of it is embedded in the conical cavity 111 and a part of it is embedded in the circular cavity 112.

[0082] Since the plug body 200 is a rubber part and can be deformed under force, the plug body 200 is set as a conical plug. During assembly, it can be continuously embedded from the top conical cavity 111 into the bottom circular cavity 112 to achieve fixation.

[0083] The conical cavity 111 is used for guiding, which can facilitate the quick assembly of the plug body 200, and the circular cavity 112 is used for positioning.

[0084] During assembly, after the conical plug is deformed, a part of it is embedded in the conical cavity 111 and a part of it is embedded in the circular cavity 112.

[0085] By setting the plug body 200 into a conical structure, the plug body 200 can be in close contact with the inner wall of the first embedding cavity after being fixed through deformation assembly, ensuring that the plug 950 is more tightly sealed.

[0086] In some embodiments, a filter screen assembly is further provided in the first embedding cavity. The filter screen assembly includes a first filter screen and a second filter screen sequentially installed in the first member 110.

[0087] In some embodiments of the present application, guiding grooves 142 are formed on the inner wall of the accommodating part 140. There are 2 guiding grooves 142, which are arranged oppositely;

[0088] The guiding and limiting assembly 500 includes:

[0089] A guiding part 510, connected to the flexible connecting piece 300, and both ends are slidably arranged in the 2 guiding grooves 142 respectively;

[0090] And a second limiting piece 520, connected to the flexible connecting piece 300 and located below the guiding part 510.

[0091] The second limiting piece 520 is a second aluminum seal, and the guiding part 510 is a circular guiding rod.

[0092] To realize the connection between the flexible connecting piece 300 and the guiding part 510, a through hole is provided on the guiding part 510.

[0093] The flexible connecting piece 300 passes through the through hole, and the inner diameter of the through hole is smaller than that of the second limiting piece 520.

[0094] When the flexible connector 300 is stressed, it will first drive the second limiting member 520 connected to its end to move. When the second limiting member 520 moves to the guiding member 510, the acting force reaches the guiding member 510 and pushes the guiding member 510 to move.

[0095] The guiding member 510 slides along the guiding grooves 142 at both ends to achieve the guiding function.

[0096] At the same time, by inserting both ends of the guiding member 510 into the guiding grooves 142, the support and positioning of the second limiting member 520 can be achieved, effectively avoiding the impact on the inner wall of the pipe caused by the shaking of the second limiting member 520.

[0097] In some embodiments of the present application, the main body member includes a second member 120, the second member 120 is threadedly connected to the first member 110, and a connecting flange 600 is connected to the second member 120.

[0098] The outer side of the second member 120 is provided with an external thread, and the first member 110 is provided with a threaded hole. The second member 120 is screwed into the first member 110 to realize the connection with the first member 110.

[0099] At the same time, the overall length between the first member 110 and the second member 120 can also be adjusted through the threaded connection between the second member 120 and the first member 110. During adjustment, the length of the second member 120 screwed into the first member 110 is changed.

[0100] The connecting flange 600 can be sleeved on the second member 120 during fixation to realize the connection with the second member 120.

[0101] By adjusting the overall length of the second member 120 and the first member 110, it can be adapted to the installation of floors with different thicknesses.

[0102] In some embodiments, the inner diameter of the first member 110 is smaller than that of the second member 120, and a clamping and limiting portion 141 is formed at the butt joint of the first member 110 and the second member 120. The clamping and limiting portion 141 is a clamping and limiting platform.

[0103] When the guiding member 510 moves to the clamping and limiting platform, it is clamped and limited.

[0104] In some embodiments of the present application, an installation groove 210 with an open bottom is formed at the bottom of the plug body 200. The first limiting member 400 is located in the installation groove 210, and the flexible connector 300 extends out from the top of the installation groove 210.

[0105] In some embodiments of the present application, it further includes: a pull ring 700, the pull ring 700 is connected to the stretching end 310, and a first elastic buffer 810 is provided between the pull ring 700 and the plug body 200;

[0106] A second elastic buffer 820 is provided between the first limiting member 400 and the top wall of the installation groove 210.

[0107] The first elastic buffer 810 is a first gasket, and the second elastic buffer is a second gasket.

[0108] By providing the first gasket and the second gasket, it can prevent the first limiting member 400, the pull ring 700 and the plug body 200 from coming into hard contact when stretching the flexible connecting member 300, and causing damage to the plug body 200.

[0109] In some embodiments of the present application, it further includes a pull ring 700, the pull ring 700 is connected to the stretching end 310, and a first elastic buffer 810 is provided between the pull ring 700 and the plug body 200;

[0110] The first limiting member 400 is located below the plug body 200, and a second elastic buffer 820 is provided between the first limiting member 400 and the bottom wall of the plug body 200.

[0111] When the plug body 200 is provided, the installation groove 210 may not be provided, and directly providing the first limiting member 400 on the flexible connecting member 300 below the plug body 200 can also achieve driving the plug body 200 to act by pulling the flexible connecting member 300.

[0112] In some embodiments of the present application, a refrigerated container is proposed, including: a refrigerated container floor, and the refrigerated container floor includes:

[0113] A bottom plate member 910, a foaming cavity 911 is formed in the bottom plate member 910, and foaming material is filled in the foaming cavity 911;

[0114] And a plurality of top plate members 920 laid above the bottom plate member 910, and the top surfaces of the plurality of top members are flush;

[0117] The installation portion 930 is an installation hole for assembling the water leakage device in the above embodiment.

[0118] During assembly, the main body member is assembled within the mounting portion 930, and the top end of the first member 110 that constitutes the main body member is welded and fixed to the top plate member 920.

[0119] After passing through the bottom, it is locked and fixed to the bottom plate member 910 through the connecting flange 600.

[0120] Specifically, the connecting flange 600 on the main body member is arranged to fit the bottom surface of the bottom plate member 910. After fixing the two with rivets, sealant is applied at the gap.

[0121] When the thickness of the foaming layer of the bottom plate member 910 in the floor is different, it may cause the water leakage detector to be unable to be installed. At this time, the screwing depth of the second member 120 relative to the first member 110 can be changed by screwing to achieve matching the requirements of floors with different thicknesses.
