The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The embodiment of the application provides a laboratory rack, and the laboratory rack is made according to the characteristics of most laboratories, matches with the size of most laboratories in the aspect of the size, can satisfy the function of most laboratories in the aspect of specifically setting up.

The terms of orientation, such as front, back, left, right, up, down, and the like, in the embodiment are used for clearly describing the laboratory cabinet, and are not limited specifically, the front side may be a side for a technician to operate, for example, the first surface of the mounting plate assembly may be used as the front side, and the top side may be the top side and the bottom side may be the bottom side of the laboratory cabinet.

As shown in fig. 1 and with reference to fig. 2, the laboratory cabinet comprises a cabinet main frame 1, at least one side plate 2, a mounting plate assembly 3 for mounting components, wherein: as shown in fig. 2, the mounting plate assembly 3 is installed in the cabinet main frame 1, as shown in fig. 1, at least one side plate 2 is detachably installed on a side wall of the cabinet main frame 1, and the mounting plate assembly 3 is perpendicular to the at least one side plate 2; as shown in fig. 3, a movable plate 4 is installed at a predetermined position on the first surface of the mounting plate assembly 3, the movable plate 4 is hinged to the mounting plate assembly 3, and as shown in fig. 3 and 4, an included angle between the movable plate 4 and the mounting plate assembly 3 is greater than or equal to 0 degree and less than or equal to 90 degrees.

The mounting plate assembly 3 is mainly used for hanging other components, for example, a PLC (Programmable Logic Controller) Controller may be installed, and a switch component and various buttons may also be installed, if there are fewer components installed in the laboratory cabinet, the mounting plate assembly 3 may only include one mounting plate, and if there are more components installed in the laboratory cabinet, the mounting plate assembly 3 may include two mounting plates, or even a plurality of mounting plates, which are installed in the cabinet main frame 1 in parallel.

In an implementation, the cabinet main frame 1 is a frame of a laboratory cabinet, and may include a top surface 11, a bottom surface 12, and a connection column 13 connecting the top surface 11 and the bottom surface 12 as shown in fig. 1, for example. As shown in fig. 2, the mounting plate assembly 3 is installed in the cabinet main frame 1, for example, as shown in fig. 2, the top of the mounting plate assembly 3 is fixed to the top surface 11 of the cabinet main frame 1, and the bottom of the mounting plate assembly 3 is fixed to the bottom surface 12 of the cabinet main frame 1. The laboratory cabinet further includes at least one side plate 2, and the side plate 2 is installed on a side wall of the main cabinet frame 1, for example, one side plate 2 is detachably installed on each of two side walls of the main cabinet frame 1, and for example, one side plate 2 is detachably installed on one side wall of the main cabinet frame 1, and a push-pull plate is installed on the other side wall (in this case, as will be described in detail below).

In an implementation, the side plates 2 are mounted on the cabinet main frame 1 through retractable buttons, specifically, as shown in fig. 5, at least one retractable button 21 is disposed on the top of the side plates 2, and the side plates 2 are detachably mounted on the side walls of the cabinet main frame 1 through retractable buttons 21. Wherein, a retractable button 21 may be disposed at the middle position of the top of the side plate 2, or as shown in fig. 5, a retractable button 21 may be disposed at each of the two end positions of the top of the side plate 2. Thus, when installing the side plate 2, a technician first buckles the bottom of the side plate 2 at the bottom of the cabinet main frame 1; then the telescopic button 21 is pressed by hand, so that the telescopic button 21 is retracted to be flush with the top of the side plate 2; then the side plates 2 are moved to be flush with the side walls of the cabinet main frame 1; finally, the technician releases the retractable button 21 with his hand, and at this time, the retractable button 21 is sprung up and buckled on the inner surface of the cabinet main frame 1, and then the side wall of the cabinet main frame 1 is clamped between the side plate 2 and the retractable button 21, so that the side plate 2 is installed on the cabinet main frame 1. When the technician detaches the side plate 2, firstly, the telescopic button 21 is pressed by hands, so that the telescopic button 21 is downwards contracted to be flush with the top of the side plate 2; then, the technician presses the retractable button 21 to outwardly snap the side plate 2 from the main frame 1 of the cabinet.

Above-mentioned curb plate 2 passes through telescopic button 21 demountable installation on rack main frame 1, can make things convenient for technical staff dismouting or debugging equipment on mounting panel subassembly 3, and then also can improve technical staff's work efficiency.

As shown in fig. 3 and 4, the mounting plate assembly 3 is provided with a movable plate 4, wherein the movable plate 4 is hinged to the mounting plate assembly 3, a hinge edge is formed at the hinge position of the movable plate 4 and the mounting plate assembly 3, and the movable plate 4 can rotate around the hinge edge, so that the included angle between the movable plate 4 and the mounting plate assembly 3 is adjusted between 0 and 90 degrees. When the included angle between the movable plate 4 and the mounting plate assembly 3 is 0 degree, as shown in fig. 4, the movable plate 4 is parallel to the mounting plate assembly 3, in which case, the movable plate 4 is folded on the mounting plate assembly 3; when the included angle between the movable plate 4 and the mounting plate component 3 is 90 degrees, as shown in fig. 3, the movable plate 4 is perpendicular to the mounting plate component 3, under the condition, the movable plate 4 is unfolded on the mounting plate component 3, and at this time, the movable plate 4 can be used for placing operating equipment, for example, a notebook computer, and also can be used for placing maintenance tools, and at this time, the movable plate 4 can be regarded as an operating platform of a laboratory cabinet, so that the operation of technicians can be facilitated.

In practice, the hinge edge between the movable plate 4 and the mounting plate assembly 3 may be located at the upper portion of the movable plate 4, or may be located at the lower portion of the movable plate 4. If the hinged edge is located at the upper portion of the movable plate 4, when the included angle between the movable plate 4 and the mounting plate assembly 3 is 0 degree (or close to 0 degree), the movable plate 4 is in a folded state, that is, the movable plate 4 is laid down on the mounting plate assembly 3; if the hinged edge is located at the lower portion of the movable plate 4, the movable plate 4 is in a folded state when the included angle between the movable plate 4 and the mounting plate assembly 3 is 0 degree (or close to 0 degree), that is, the movable plate 4 stands on the mounting plate assembly 3. The specific position of the hinged edge is not limited in this embodiment, and a technician can flexibly set the hinged edge according to needs, but the hinged edge is located on the upper portion of the movable plate 4, so that the movable plate 4 can be prevented from rotating around the hinged edge under the action of gravity when in a folded state, and the safety can be further improved.

Alternatively, in order to enable the movable plate 4 to bear a certain weight, the movable plate 4 may be hinged to the mounting plate assembly by an elastic member having a larger elastic coefficient, or the lower surface of the movable plate 4 may be supported on the mounting plate assembly 3 by a movable support member, for example, when the included angle between the movable plate 4 and the mounting plate assembly 3 is equal to 90 degrees, as shown in fig. 3 and 4, the movable plate 4 is supported on the mounting plate assembly 3 by a support member 5, and the support member 5 is fixed to the lower surface of the movable plate 4 and the first surface of the mounting plate assembly 3, respectively.

In practice, as shown in fig. 3 and 4, the support assembly 5 may include a support rod 51, a first end of the support rod 51 is hinged to the mounting plate assembly 3, and a second end of the support rod 51 is detachably fixed to the lower surface of the movable plate 4. Thus, when a technician needs to place things on the movable plate 4 (for example, when a notebook computer needs to be placed), the movable plate 4 can be moved to be perpendicular to the mounting plate assembly 3, and at the same time, the support rod 51 is pulled off, so that the first end of the support rod 51 rotates around the hinge joint with the mounting plate assembly 3, and the second end of the movable plate 4 supports the movable plate 4. Further, the movable plate 4 may be perpendicular to the mounting plate assembly 3 under the support of the support rod 51 of the support assembly 5, so that a technician may place equipment, etc. on the upper surface of the movable plate 4.

Alternatively, when the movable plate 4 is perpendicular to the mounting plate assembly 3, in order to fix the second end of the support rod 51 to the lower surface of the movable plate 4, the second end of the support rod 51 may be fixed to the lower surface of the movable plate 4 by a bolt. The second end of the supporting rod 51 can be clamped on the lower surface of the movable plate 4 by a clamping, for example, a clamping groove can be formed at a position of the lower surface of the movable plate 4 corresponding to the supporting rod 51, so that when the movable plate 4 is perpendicular to the mounting plate assembly 3, a technician can move the supporting rod 51 to clamp the second end of the supporting rod 51 in the clamping groove on the lower surface of the movable plate 4.

Alternatively, for the sake of processing convenience, the supporting component 5 may also include a supporting rod and two fixing portions, one of the two fixing portions is fixed on the movable plate 4, the other is fixed on the mounting plate component 3, and the supporting rod is fixed on one of the fixing portions. A corresponding structure may be that, as shown in fig. 6, the support assembly 5 further includes a first fixing portion 52 fixed on the first surface of the mounting plate assembly 3 and a second fixing portion 53 fixed on the lower surface of the movable plate 4, when the included angle between the movable plate 4 and the mounting plate assembly 3 is 90 degrees, the first fixing portion 52 is perpendicular to the second fixing portion 53; as shown in fig. 7, a locking groove 531 is formed at a predetermined position of the second fixing portion 53 to be engaged with the second end of the supporting rod 51; the first end of the supporting rod 51 is hinged to the first fixing portion 52, and when the included angle between the movable plate 4 and the mounting plate assembly 3 is 90 degrees, as shown in fig. 7, the second end of the supporting rod 51 is located in the clamping groove 531 of the second fixing portion 53.

The second end of the supporting rod 51 is matched with the locking groove 531 to lock (or support) the supporting rod 51 on the lower surface of the movable plate 4, so that the movable plate 4 has a certain bearing capacity, and a certain weight of objects (such as a notebook computer) can be placed on the upper surface of the movable plate.

In an embodiment, the first fixing portion 52 and the second fixing portion 53 may have a long bar shape, a cross-sectional shape along the width direction may be a U-shape, and the overall shape may be a channel shape. The first fixing portion 52 is fixed on the mounting plate assembly 3, the second fixing portion 53 is fixed on the lower surface of the movable plate 4, and when the movable plate 4 is perpendicular to the mounting plate assembly 3, as shown in fig. 6, the first fixing portion 52, the second fixing portion 53 and the support rod 51 enclose a right triangle, so that the movable plate 4 is fixed on the mounting plate assembly 3 by the stability of the triangle.

For convenience of description, an end of the first fixing portion 52 close to the hinge edge of the movable plate 4 and the mounting plate assembly 3 is referred to as a first end of the first fixing portion 52, an end far away from the hinge edge is referred to as a second end of the first fixing portion 52, an end of the second fixing portion 53 close to the hinge edge is referred to as a first end of the second fixing portion 53, and an end far away from the hinge edge is referred to as a second end of the second fixing portion 53.

In an embodiment, the movable plate 4 is hinged to the mounting plate assembly 3, the first fixing portion 52 is fixed to the mounting plate assembly 3, and the second fixing portion 53 is fixed to the movable plate 4, so that the first fixing portion 52 and the second fixing portion 53 can also be hinged, for example, a first end of the first fixing portion 52 is hinged to a second end of the second fixing portion 53. Of course, since the movable plate 4 is hinged to the mounting plate assembly 3, the first fixing portion 52 and the second fixing portion 53 may not be hinged to each other, and this embodiment is not limited thereto, and the first fixing portion 52 and the second fixing portion 53 are only for conveniently mounting the supporting rod 51.

Optionally, in order to improve the flexibility of the detachment between the support rod 51 and the movable plate 4, a corresponding structure may be that, as shown in fig. 6, the support assembly 5 further includes a shift lever 54, and a first preset position of the shift lever 54 is fixed on the second fixing portion 53 through a screw sleeved with a spring, where the screw sleeved with the spring is a movable fulcrum of the shift lever 54. When the movable plate 4 is perpendicular to the mounting plate assembly 3, the first end of the shift lever 54 is located between the second fixing portion 53 and the support rod 51, and the first end of the shift lever 54 is an end close to the hinged edge of the movable plate 4 and the mounting plate assembly 3; when the second end of the lever 54 moves to a predetermined position toward the second fixing portion 53, the second end of the support rod 51 is separated from the engaging groove 531 by the first end of the lever 54, and the second end of the lever 54 is opposite to the first end of the lever 54.

For convenience of description, an end of the shift lever 54 near the hinge edge of the movable plate 4 and the mounting plate assembly 3 is referred to as a first end, and an end opposite to the first end is referred to as a second end.

The first predetermined position of the shift lever 54 may be a position between the first end and the second end of the shift lever 54, such as a middle position, or other positions, which is not limited in this embodiment.

In an implementation, the shift lever 54 has a long bar-shaped structure, and two ends of the shift lever 54 can move around using a screw sleeved with a spring as a fulcrum, for example, when a technician presses the second end of the shift lever 54, the first end of the shift lever 54 can tilt up relative to the screw sleeved with the spring, and the principle of the shift lever 54 is similar to that of a seesaw. The shift lever 54 is mainly used for shifting the second end of the supporting rod 51, so that the second end of the supporting rod 51 is separated from the engaging groove 531 of the second fixing portion 53, and the movable plate 4 can be placed down, that is, the movable plate 4 is rotated around the hinge edge to be parallel to the mounting plate assembly 3. For example, in the case that the movable plate 4 is perpendicular to the mounting plate assembly 3, the second end of the support rod 51 is clamped in the clamping groove 531 of the second fixing portion 53, and the first end of the shift lever 54 is located between the support rod 51 and the second fixing portion 53. In this way, when the user presses the second end of the lever 54, that is, the second end of the lever 54 moves to the predetermined position toward the second fixing portion 53, the first end of the lever 54 toggles the second end of the supporting rod 51, and then the second end of the supporting rod 51 is separated from the locking groove 531 under the action of force, so that the supporting rod 51 no longer supports the movable plate 4, at this time, the technician can place the movable plate 4, that is, the movable plate 4 is parallel to the mounting plate assembly 3 due to the vertical arrangement of the mounting plate assembly 3.

Alternatively, when the technician intends to rotate the movable plate 4 from being parallel to the mounting plate assembly 3 to being perpendicular to the mounting plate assembly 3, and correspondingly, the technician lifts the movable plate 4 upward until the second end of the supporting rod 51 is clamped in the clamping groove 531 of the second fixing portion 53, in order to improve the operation efficiency of the technician, correspondingly, as shown in fig. 6, an elastic member 6 is disposed between the supporting rod 51 and the first fixing portion 52, the elastic member 6 is located above the supporting rod 51, and when the movable plate 4 is parallel to the mounting plate assembly 3, that is, when the lower surface of the movable plate 4 is in contact with the first surface of the mounting plate assembly 3, the elastic member 6 is in a stretching state.

The elastic member 6 may be a spring, or may be an elastic rubber band.

In implementation, as shown in fig. 6, the first end of the elastic member 6 may be fixed to the first end of the first fixing portion 52, or the first end of the elastic member 6 may be fixed to a hinge between the first fixing portion 52 and the second fixing portion 53. The second end of the elastic member 6 may be fixed to the middle of the support rod 51, or the second end of the elastic member 6 may be fixed to a position near the second end of the support rod 51. In this embodiment, the fixing positions of the two ends of the elastic component 6 are not limited, and the elastic component 6 can pull the second end of the supporting rod 51 to rotate upward. Thus, under the condition that the movable plate 4 is parallel to the mounting plate assembly 3, when the technician lifts the movable plate 4, the elastic component 6 can pull the support rod 51, so that the second end of the support rod 51 can rotate upwards around the first end until the movable plate 4 is lifted to be perpendicular to the mounting plate assembly 3, the second end of the support rod 51 is clamped in the clamping groove 531 of the second fixing portion 53, and thus, under the action of the elastic component 6 pulling the support rod 51, the technician does not need to manually clamp the second end of the support rod 51 in the clamping groove 531, thereby facilitating the operation of the technician.

Optionally, in order to further enable the elastic component 6 to pull the second end of the supporting rod 51 to move upward, a corresponding structure may be that, as shown in fig. 6, a hook 541 matched with the second end of the supporting rod 51 is disposed at a second preset position of the shift lever 54, and when the included angle between the movable plate 4 and the mounting plate assembly 3 is equal to 0 degree, the second end of the supporting rod 51 is located in the hook 541.

Wherein, the hook 541 is an L-shaped hook, and the hook 541 is bent toward the hinged edge between the movable plate 4 and the mounting plate assembly 3.

The second predetermined position of the lever 54 is related to the distance between the second end of the support rod 51 and the hinged edge.

In practice, the main function of the hook 541 is to lift the second end of the supporting rod 51 during the process of adjusting the movable plate 4 from being parallel to the mounting plate assembly 3 to being perpendicular to the mounting plate assembly 3, so that the second end of the supporting rod 51 can rotate upwards under the pulling of the elastic component 6. The distance between the fixing portion of the hook 541 and the lever 54 and the hinge edge (the hinge edge between the movable plate 4 and the mounting plate assembly 3) is equal to the distance between the second end of the support rod 51 and the hinge edge when the support rod 51 is attached to the mounting plate assembly 3, so that the second end of the support rod 51 can be located in the hook 541 when the lower surface of the movable plate 4 is in contact with the first surface of the mounting plate assembly 3. Furthermore, when the movable plate 4 is parallel to the mounting plate assembly 3, when a technician starts to lift the movable plate 4, since the second end of the supporting rod 51 is located in the hook 541, the hook 541 can trigger the second end of the supporting rod 51 to move in a direction perpendicular to the supporting rod 51, and then, even if the second end of the supporting rod 51 is separated from the hook 541, the second end of the supporting rod 51 continues to rotate upward under the action of the elastic component 6 until the second end of the supporting rod 51 is clamped in the clamping groove 531.

Based on the above structure, the movable plate 4 can be hung on the mounting plate assembly 3, that is, the lower surface of the movable plate 4 contacts with the first surface of the mounting plate assembly 3, the movable plate 4 can be perpendicular to the mounting plate assembly 3, and under the action of the supporting assembly 5, the movable plate has a certain bearing capacity, so that some objects can be placed on the upper surface of the movable plate 4, for example, a notebook computer can be placed, and an overhaul tool and the like can be temporarily placed.

Optionally, a push-pull plate may be further installed on the side wall of the main cabinet frame 1 of the laboratory cabinet, and the corresponding structure may be, as shown in fig. 8, a push-pull plate 8 is installed on the side wall of the main cabinet frame 1, on which the side plate 2 is not installed, through three-section guide rails 7, and a pulley is installed at the bottom of the push-pull plate 8.

In implementation, the three-section guide rail 7 is a guide rail structure including an inner rail, a middle rail and an outer rail, the inner rail may also be referred to as a movable rail, the outer rail may also be referred to as a fixed rail, the inner rail of the three-section guide rail 7 may be mounted on the push-pull plate 8, and the outer rail may be mounted on the cabinet main frame 1. The bottom of the push-pull plate 8 is further provided with a pulley, for example, a pulley may be arranged in the middle of the bottom of the push-pull plate 8, or a pulley may be arranged at each of the two ends of the bottom of the push-pull plate 8. Thus, the push-pull plate 8 can move relative to the cabinet main frame 1, and when the two ends of the push-pull plate 8 are aligned with the front and rear connecting columns 13 of the cabinet main frame 1, the push-pull plate 8 can be used as a side plate of the laboratory cabinet. In order to facilitate the pulling of the push-pull plate 8 by the technician, the side of the push-pull plate 8 along the pulling direction is correspondingly provided with a handle 81 for pulling the push-pull plate 8, so as to facilitate the pulling or pushing of the push-pull plate 8 by the technician.

In a possible implementation, a plurality of laboratory cabinets can be placed in a laboratory, and the laboratory cabinets can be next to each other, in which case, a push-pull plate 8 can be installed on a side wall of one of two adjacent laboratory cabinets, that is, a side plate 2 is installed on one side wall of a main cabinet frame 1 of the laboratory cabinet, and a push-pull plate 8 is installed on the other side wall opposite to the side wall. Of course, the two side walls of the laboratory cabinet may also be both provided with the side plate 2, or both provided with the push-pull plate 8, which is not limited in this embodiment, and technicians may flexibly set the side plates according to requirements.

In one possible application scenario, the laboratory cabinets may be used in a racing activity, in which a technician may unfold the movable plate 4 in a folded state, that is, the technician may adjust the movable plate 4 to be perpendicular to the mounting plate assembly 3 from being parallel to the mounting plate assembly 3, and may pull out the push-pull plate 8 between two adjacent laboratory cabinets to form a partition between the two adjacent laboratory cabinets. At this time, the technician can place the notebook computer on the movable plate 4 to perform competition operations and the like.
