Abstract
Description
Technical Field
[0001] The present application relates to the field of sampling cabinets, and in particular, to an interlocking device and a sampling cabinet. Background Art
[0002] The sampling operation room and the sampling liquid receiving room are integrated on the same sampling cabinet. A sampling valve is provided in the sampling operation room. The sampling liquid receiving room is used for sampling. The cabinet door of the sampling operation room and the cabinet door of the sampling liquid receiving room can be opened at the same time when sampling liquid. As a result, when sampling, the operator takes the sampling bottle in the sampling liquid receiving room without closing the sampling valve, causing liquid to spray out, posing a safety hazard. After the sampling is completed, the operator opens the door of the sampling liquid receiving room to take the sampling bottle. During this process, since the door of the sampling operation room can be opened at will, the sampling valve may be opened by mistake when taking the sampling bottle, causing liquid overflow. Utility Model Content
[0003] The purpose of the embodiments of the present application is to provide an interlocking device and a sampling cabinet, which can prevent two adjacent cabinet doors from being opened at the same time, thereby alleviating or avoiding safety issues caused by interference in the use of two operating rooms due to the simultaneous opening of two cabinet doors.
[0004] In a first aspect, an embodiment of the present application provides an interlocking device for being arranged on a cabinet, wherein the cabinet is provided with at least two operating rooms and cabinet doors corresponding to each operating room, and the cabinet doors are configured to be able to open the corresponding operating room to a side away from the cabinet.
[0005] The interlocking device includes a fixed base, a limiting plate and a handle.
[0006] Among them, the fixed base is used to be installed on the cabinet body; the limiting plate is rotatably installed on the fixed base via a rotating shaft, and the limiting plate is located on the side of the cabinet door away from the cabinet body; the handle is connected to the rotating shaft so as to be rotatably installed on the fixed base, and the handle is used to drive the limiting plate to rotate between two adjacent cabinet doors, so that the limiting plate can selectively abut against at least one cabinet door and cannot be separated from the two cabinet doors at the same time.
[0007] In the above implementation process, by improving the structure of the interlocking device, when it is installed on the cabinet body and the limit plate can be rotated between two adjacent cabinet doors, the limit plate can be driven by the handle to selectively abut at least one of the cabinet doors and cannot be separated from the two cabinet doors at the same time. This can prevent the two adjacent cabinet doors from being opened at the same time, and can alleviate or avoid safety problems caused by interference in the use of two operating rooms due to the simultaneous opening of the two cabinet doors.
[0008] In a possible implementation, the interlocking device further includes two blocking pins disposed on the fixed base and used to limit the rotation of the handle between the first maximum rotation angle and the second maximum rotation angle. When the handle is at the first maximum rotation angle, the limiting piece abuts against one of the cabinet doors, and when the handle is at the second maximum rotation angle, the limiting piece abuts against the other cabinet door.
[0009] In the above implementation process, the maximum rotation angle of the handle can be directly limited by the two blocking pins, so as to quickly realize that the limiting piece can abut against one of the cabinet doors and cannot disengage from the two cabinet doors at the same time.
[0010] In a possible implementation, the blocking pin is detachably connected to the fixed base.
[0011] In the above implementation process, the detachable connection method is beneficial to maintenance. And in the special case where it is necessary to open two cabinet doors at the same time, the handle can be rotated 360° by removing the blocking pin to realize the simultaneous opening of the two cabinet doors.
[0012] In a possible implementation, the two blocking pins are symmetric about the axis center.
[0013] In a possible implementation, the fixed base includes a panel and a fixing part. The rotating shaft is rotatably installed on the panel, and the fixing part is connected to the panel. The fixing part is used to connect to the cabinet body and make the panel suspended above the cabinet body, so as to form a receiving cavity between the panel and the cabinet body, and the limiting piece can be selectively received in the receiving cavity.
[0014] In the above implementation process, by selectively receiving the limiting piece in the receiving cavity, not only can the overall structure of the interlocking device be compact and the space utilization rate be high, but also the panel can be used to protect the limiting piece and extend the service life of the limiting piece.
[0015] In a possible implementation, the limiting piece includes a connecting part and a limiting part. One end of the connecting part is connected to the rotating shaft, and the other end is connected to the limiting part. Both ends of the limiting part extend out of the connecting part and are symmetrically arranged along the connecting part.
[0016] In the above implementation process, the above setting has a simple structure, can make the overall structure of the interlocking device compact on the basis of realizing that two adjacent cabinet doors cannot be opened at the same time, and is beneficial to improving the space utilization rate.
[0017] In a possible implementation, the limiting part has an outer edge facing away from the connecting part, and the outer edge is an arc protruding toward the side away from the connecting part.
[0018] In the above implementation process, by setting the outer edge of the limiting part to be arc-shaped, it is beneficial to maintain a large contact area between the limiting piece and each cabinet door during the rotation process, which is beneficial to improving the stability of locking the cabinet door.
[0019] In a possible implementation scheme, the handle is located on a side of the fixed base facing away from the cabinet, and the limiting piece is located on a side of the fixed base close to the cabinet.
[0020] In the above implementation process, by controlling the handle and the limit plate to be located on opposite sides of the fixed seat, it is not only convenient to use the handle, but also beneficial for the limit plate to closely abut against the cabinet door during rotation, thereby improving the closing effect of the cabinet door.
[0021] In a possible implementation manner, the handle, the rotating shaft, and the limiting plate are detachably connected.
[0022] In the above implementation process, the handle, rotating shaft, and limiting plate are detachably connected to form an interlocking device, which improves the convenience of assembly. It is also convenient to replace only one component when any component is damaged, effectively reducing maintenance costs.
[0023] In a second aspect, an embodiment of the present application provides a sampling cabinet, which includes a cabinet body and the interlocking device provided in the first aspect of the present application.
[0024] The cabinet body is provided with at least two operating rooms and cabinet doors corresponding to the operating rooms one by one, and the cabinet doors are configured to be able to open the corresponding operating room toward a side away from the cabinet body.
[0025] The fixed base is installed on the cabinet body, the limit plate is located on the side of the cabinet door away from the cabinet body, and the handle is used to drive the limit plate to rotate between two adjacent cabinet doors so that the limit plate can selectively abut at least one of the cabinet doors and cannot be separated from the two cabinet doors at the same time.
[0026] In the above implementation process, an interlocking device is installed on the cabinet body and a handle is used to drive the limit plate to rotate between two adjacent cabinet doors, so that the limit plate can selectively abut at least one of the cabinet doors and cannot be separated from the two cabinet doors at the same time. This can prevent the two adjacent cabinet doors from being opened at the same time, and can alleviate or avoid safety problems caused by interference in the use of the two operating rooms due to the simultaneous opening of the two cabinet doors.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0034] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0035] See also Figure 1 The present application provides a sampling cabinet 1000 , which includes a cabinet body 10 and an interlocking device 20 .
[0036] The cabinet body 10 is provided with at least two operating rooms (not shown) and cabinet doors 11 corresponding to the operating rooms one by one. The cabinet doors 11 are configured to be able to open the corresponding operating room toward a side away from the cabinet body 10 .
[0037] The at least two here can be, for example, two, three, four, etc., which can be selected according to actual needs.
[0038] like Figure 1 As shown, the cabinet body 10 is provided with two operating rooms and two cabinet doors 11 corresponding to the two operating rooms one by one.
[0039] The two operating rooms can be arranged up and down or left and right. Figure 1 As shown, two operating chambers are arranged up and down, one of the operating chambers is a sampling operating chamber, and the other operating chamber is a sampling liquid receiving chamber, and the sampling operating chamber is above the sampling liquid receiving chamber.
[0040] The interlocking device 20 includes a fixed base 21 , a limiting piece 22 and a handle 23 .
[0041] Among them, the fixed base 21 is installed on the cabinet body 10; the limiting plate 22 is rotatably installed on the fixed base 21 via a rotating shaft, and the limiting plate 22 is located on the side of the cabinet door 11 away from the cabinet body 10; and the handle 23 is connected to the rotating shaft so as to be rotatably installed on the fixed base 21, and the handle 23 is used to drive the limiting plate 22 to rotate between two adjacent cabinet doors 11, so that the limiting plate 22 can selectively abut against at least one cabinet door 11 and cannot be separated from the two cabinet doors 11 at the same time.
[0042] It can be understood that the limit plate 22 is rotatably mounted on the fixed base 21 via the rotating shaft, and the handle 23 is connected to the rotating shaft so as to be rotatably mounted on the fixed base 21. Therefore, the handle 23, the rotating shaft, and the limit plate 22 are connected together. Therefore, the limit plate 22 can be synchronously driven to rotate by the handle 23, so that the handle 23 drives the limit plate 22 to rotate between two adjacent cabinet doors 11.
[0043] Since the limiting plate 22 can rotate between two adjacent cabinet doors 11 driven by the handle 23, and the limiting plate 22 can selectively abut against at least one of the two cabinet doors 11 during the rotation process and cannot simultaneously separate from the two adjacent cabinet doors 11, that is, when the handle 23 drives the limiting plate 22 to rotate, the two cabinet doors 11 can be closed at the same time, and a single cabinet door 11 can be opened or closed, but the two cabinet doors 11 cannot be opened at the same time.
[0044] At this time, during actual use, the operator opens the cabinet door 11 of the sampling liquid receiving chamber, places the sampling bottle in the sampling liquid receiving chamber. During this process, it is necessary to rotate the rotary handle 23 to the upper end to restrict the opening of the sampling operation chamber, so as to avoid opening the sampling valve when the door of the sampling liquid receiving chamber is not properly closed, resulting in liquid splashing and causing safety accidents. After the sampling bottle is placed in place, close the cabinet door 11 corresponding to the door of the sampling liquid receiving chamber. The operator needs to rotate the rotary handle 23 to the lower end to restrict the opening of the sampling liquid receiving chamber, so as to avoid opening the sampling liquid receiving chamber and taking the sampling bottle when the operator has not closed the valve, resulting in liquid spilling and causing production safety accidents. This device can achieve the interlock of the cabinet door 11 of the sampling liquid receiving chamber and the cabinet door 11 of the sampling operation chamber, and to a certain extent, it can reduce the risk of liquid splashing and overflow caused by human misoperation, achieving the purpose of safe production.
[0045] In summary, through the above structural improvement of the interlock device 20, the two adjacent cabinet doors 11 cannot be opened simultaneously, which can alleviate or avoid the safety problems caused by the interference in the use of the two operation chambers when the two cabinet doors 11 are opened simultaneously.
[0046] Among them, the handle 23, the rotating shaft, and the limiting piece 22 can be integrally formed. For the convenience of installation and disassembly, the handle 23 and the rotating shaft can be integrally formed, the limiting piece 22 is detachably connected to the rotating shaft, or the limiting piece 22 and the rotating shaft can be integrally formed, the handle 23 is detachably connected to the rotating shaft, or the handle 23, the rotating shaft, and the limiting piece 22 are respectively detachably connected.
[0047] As Figure 2 shown, in this embodiment, the handle 23, the rotating shaft, and the limiting piece 22 are respectively detachably connected.
[0048] The detachable connection method here includes but is not limited to snap connection or threaded connection, etc., which can be selected according to actual needs.
[0049] The above setting method of the handle 23, the rotating shaft, and the limiting piece 22 being respectively detachably connected is convenient for assembling the above three with the fixed seat to form the interlock device 20, improving the convenience of assembly. At the same time, it is also convenient to replace only the damaged part when any part is damaged, effectively reducing the maintenance cost.
[0050] Among them, the handle 23 and the limiting piece 22 can both be located on the side of the fixed base 21 away from the cabinet body 10.
[0051] Please refer to Figure 2In this embodiment, the handle 23 and the limiting piece 22 are respectively located on opposite sides of the fixed base 21, wherein the handle 23 is located on the side of the fixed base 21 away from the cabinet 10, and the limiting piece 22 is located on the side of the fixed base 21 close to the cabinet 10. Through the above arrangement, not only is it convenient to use the handle 23, but also the limiting piece 22 can be closely abutted against the cabinet door 11 during the rotation process, thereby improving the sealing effect of the cabinet door 11 on the operating room.
[0052] Please continue reading Figure 2 The fixed base 21 includes a panel 210 and a fixing portion 211. The rotating shaft can be rotatably installed on the panel 210. The fixing portion 211 is connected to the panel 210. The fixing portion 211 is used to connect to the cabinet 10 and make the panel 210 suspended from the cabinet 10, so that a accommodating cavity 24 is formed between the panel 210 and the cabinet 10, and the limiting piece 22 can be selectively accommodated in the accommodating cavity 24.
[0053] By selectively accommodating the limiting piece 22 in the accommodating cavity 24 , the overall structure of the interlocking device 20 can be compact and space utilization rate is high, and the limiting piece 22 can be protected to a certain extent by the panel 210 .
[0054] In some other embodiments, the panel 210 and the fixing portion 211 may be arranged in an “L”-like shape.
[0055] like Figure 2 As shown, in this embodiment, there are two fixing parts 211 , which are respectively located at two ends of the panel 210 , and one end of each fixing part 211 is connected to the cabinet 10 , and the other end is connected to the panel 210 .
[0056] The above arrangement is helpful to further improve the stability of the connection between the panel 210 and the cabinet 10 .
[0057] In order to improve the stability of the structure, the fixing portion 211 and the panel 210 are integrally formed.
[0058] It can be understood that the fixing portion 211 is detachably connected to the cabinet 10 , and the detachable connection here is, for example, a snap connection or a bolt connection.
[0059] Please continue reading Figure 2 The limiting piece 22 includes a connecting portion 221 and a limiting portion 222 . One end of the connecting portion 221 is connected to the rotating shaft, and the other end is connected to the limiting portion 222 . Both ends of the limiting portion 222 extend out of the connecting portion 221 and are symmetrically arranged along the connecting portion 221 .
[0060] That is, the limiting piece 22 is arranged in a "T" shape as a whole. The above arrangement has a simple structure and can make the overall structure of the interlocking device 20 compact on the basis of preventing two adjacent cabinet doors 11 from being opened at the same time, which is beneficial to improving space utilization.
[0061] As shown Figure 2 in FIG. Figure 2 , the limiting portion 222 has an outer edge facing away from the connecting portion 221, and the outer edge is an arc protruding toward the side away from the connecting portion 221.
[0062] Since the moving track of the limiting piece 22 is an arc, therefore, by setting the outer edge to be an arc, it is beneficial to maintain a large contact area between the limiting piece 22 and each cabinet door 11 during the rotation process.
[0063] During actual use, the damping exists between the rotating shaft and the fixed base 21. By applying an appropriate force by the user to rotate the handle 23, the rotation angle of the handle 23 can be limited, so that the limiting piece 22 can abut against at least one cabinet door 11 and cannot disengage from two cabinet doors 11 simultaneously.
[0064] In this embodiment, the interlocking device 20 further includes two resisting pins 25. The two resisting pins 25 are arranged on the fixed base 21 and are used to limit the rotation of the handle 23 between the first maximum rotation angle and the second maximum rotation angle. Among them, when the handle 23 is at the first maximum rotation angle, the limiting piece 22 abuts against one of the cabinet doors 11, and when the handle 23 is at the second maximum rotation angle, the limiting piece 22 abuts against the other cabinet door 11.
[0065] It can be understood that the maximum rotation angle here is the maximum rotation angle at which the limiting piece 22 can abut against any one of the cabinet doors 11 and cannot disengage from two cabinet doors 11 simultaneously.
[0066] Through the above settings, by setting the rotation angle of the handle 23, it can be quickly realized that the limiting piece 22 can abut against at least one cabinet door 11 and cannot disengage from two cabinet doors 11 simultaneously.
[0067] As shown Figure 2 in FIG. Figure 2 , the two resisting pins 25 are arranged on the panel 210 of the fixed base 21 and protrude from the side of the panel 210 facing away from the cabinet body 10.
[0068] Among them, the resisting pin 25 can be integrally formed with the fixed base 21, welded or other fixedly connected, or can be detachably connected by clamping, threaded connection, etc.
[0069] In this embodiment, the resisting pin 25 is detachably connected to the fixed base 21.
[0070] The detachable connection method is beneficial for maintenance, and in the special requirement of simultaneously opening two cabinet doors 11, the handle 23 can be rotated by 23° by removing the resisting pin 25 to realize the simultaneous opening of the two cabinet doors 11.
[0071] As shown Figure 2 in FIG. Figure 2 , the two resisting pins 25 are symmetric about the center of the rotating shaft.
[0072] In summary, the interlocking device and the sampling cabinet provided by the present application can, through the improvement of the structure of the interlocking device, prevent two adjacent cabinet doors from being opened simultaneously, thereby alleviating or avoiding the safety problems caused by the interference in the use of two operation rooms due to the simultaneous opening of the two cabinet doors.
[0073] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
