Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.

Please refer to fig. 1-5, a one-driving-multiple refrigerator pressure monitoring device, comprising a cabinet body 1 and a hinge 8, wherein one side of the cabinet body 1 is provided with two cabinet doors 2, the upper and lower ends of one side of each cabinet door 2 are rotatably connected with the cabinet body 1 through the hinge 8, a structural cavity 3 is formed inside each cabinet door 2, a pressure sensor 4 is installed in each structural cavity 3, the output end of each pressure sensor 4 extends into the cabinet body 1, a controller 5 and a warning lamp 6 which are used in cooperation with the pressure sensor 4 are further arranged in each structural cavity 3, the lamp surface of each warning lamp 6 is positioned on the outer side of each cabinet door 2, the pressure sensors 4 and the warning lamps 6 are both electrically connected with the controller 5, a connecting piece is arranged between the lower end of each cabinet door 2 and the cabinet body 1, and an overload assembly is further arranged on each structural cavity 3;

through setting up the connecting piece and cooperating with pressure sensor 4 and controller 5, can give the realization and control the slow self-closing of cabinet door 2 when cabinet door 2 fails to normally close to prevent that 1 inside temperature of the cabinet body from lasting rising and leading to food rotten, and be provided with the overload subassembly and can realize that cabinet door 2 closes when the in-process receives the resistance, stop to continue to close cabinet door 2, prevent to press from both sides and hinder the user.

Referring to fig. 4 and 5, the connecting piece includes a mounting block 7 mounted on the cabinet body 1, a connecting rod 9 is rotatably mounted at the upper end of the mounting block 7, a connecting block 10 is mounted at one end of the connecting rod 9 far away from the mounting block 7, the upper end of the connecting block 10 is inserted into the structural cavity 3, a chute 11 matched with the connecting block 10 for use is formed in the cabinet door 2, an air cylinder 14 electrically connected with the controller 5 is mounted in the structural cavity 3, the output end of the air cylinder 14 is connected with an L-shaped rod 12, and a fixing block 13 facing the connecting block 10 is mounted at one end of the L-shaped rod 12;

when the cabinet door 2 is opened, the connecting rod 9 can be driven to rotate around the connecting position of the connecting rod and the mounting block 7, the position of the connecting block 10 in the sliding groove 11 is changed, when the controller 5 sends an instruction to the air cylinder 14 to start, the air cylinder 14 can drive the connecting block 10 to move through the L-shaped rod 12 and the fixing block 13, and the connecting block 10 drives the cabinet door 2 to rotate to the cabinet body 1 to be closed through the mutual relation with the connecting rod 9.

Referring to fig. 3 and 4, the overload assembly includes a movable block 15 which is inserted onto the fixed block 13 in an interference manner, a touch plate 16 is installed at one end of the movable block 15 close to the connecting block 10, a micro switch 17 is installed at the upper end of the fixed block 13, the micro switch 17 is electrically connected with the controller 5, and the upper portion of the touch plate 16 is located at one side of the micro switch 17;

resistance that is greater than when connecting block 10 removes that damping intensity with the removal of movable block 15 sets up to can not drive movable block 15 when connecting block 10 normally removes and remove, and when cabinet door 2 received extra resistance, the unable movable block 15 that removes of connecting block 10 then can appear removing, trigger micro-gap switch 17 through touch panel 16 and to 5 transmission signals of controller, control cylinder 14 shut down resets, thereby prevents that cabinet door 2 from closing the in-process and pressing from both sides and hindering the user.

Referring to fig. 4, an L-shaped block 19 is installed on one side of the fixed block 13 away from the contact plate 16, and a spring 18 is installed between the movable block 15 and the L-shaped block 19;

the springs 18 and the L-shaped blocks 19 can provide resistance to ensure that the moving resistance of the movable block 15 is greater than that of the connecting block 10 after the movable block 15 has been worn to reduce the damping strength after moving back and forth for a long time.

Referring to fig. 3 and 5, the length of the sliding groove 11 is greater than the horizontal length between the two ends of the connecting rod 9, and the width of the sliding groove 11 is equal to the diameter of the connecting block 10;

the arrangement can ensure that the length of the sliding chute 11 is enough for the connecting rod 9 to open and close for at least 90 degrees, and the sliding chute 11 can also play a limiting role in the connecting block 10.

Referring to fig. 3, a certain distance is formed between the fixed block 13 and the connecting block 10, and the length of the distance is not less than the length of the sliding groove 11;

when the user normally opens and closes the cabinet door 2 manually, the fixing block 13 does not influence the normal movement of the connecting block 10.

The working principle is as follows: after the user opens cabinet door 2, the angular rotation of connecting rod 9 changes, connecting block 10 can remove in spout 11, if the user does not close cabinet door 2, the pressure that pressure sensor 4 monitored is external pressure, be less than the preset pressure that should have in the cabinet body 1, pressure sensor 4 can signal and give controller 5, controller 5 sends the time delay instruction, control warning light 6 lights, and start cylinder 14, cylinder 14 drives L shape pole 12 and fixed block 13 and removes, fixed block 13 drives connecting block 10 and removes, connecting block 10 drives connecting rod 9 angle gyration, can drive cabinet door 2 rotation and close when following connecting block 10 gyration of connecting rod 9, thereby realize when the user forgets to close cabinet door 2 or close not tight, can close through pressure change automatic control cabinet door 2, and send out warning signal, and when receiving the resistance in 2 automatic closing process, fixed block 13 can drive touch panel 16 through extrusion connecting block 10 and remove, touch panel 16 triggers micro-gap switch 17, micro-gap switch 17 case controller 5 sends out the signal, control cylinder 14 stops the machine and resets warning light, thereby prevent that automatic closing user from hindering 2 in-process.

The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the protection scope of the present invention by replacing or changing the technical solution and the modified concept of the present invention within the technical scope of the present invention.
