Description

Technical Field

[0001] The utility model relates to the technical field of mechanical opening mechanisms, in particular to a cabinet clutch-type opening mechanism. Background Art

[0002] The main opening forms of existing cabinets are motor opening or hand-cranking opening. The opening and closing of the cabinet can be realized through a clutch device. The clutch device is electrically opened, with a simple and clear mechanism, high cost performance, time-saving and labor-saving operation, and realizes the common use of electric clutch opening and hand-cranking opening.

[0003] Since there are many cabinets in museums or exhibition halls, when raising or lowering exhibits, the electric clutch devices in multiple cabinets can be simultaneously controlled through an external control system (such as a PLC control system) to realize the lifting and lowering of all exhibits, which is time-saving and labor-saving and extremely convenient. However, when it is necessary to replace the exhibits in a single cabinet, lift or adjust the height of the exhibits in a single cabinet, the cabinet controlled by the electric clutch device for lifting and lowering the exhibits is not convenient for single control and often requires operation on the interface of the external control system. However, in this process, it is necessary to return to the control room and observe the height of the exhibits multiple times, which is obviously very troublesome. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cabinet clutch-type opening mechanism, which can solve the problem that the cabinets in the exhibition hall cannot be uniformly controlled by an external control platform and single-controlled at the same time.

[0007] Preferably, the steering mechanism includes at least three right-angle steering gears and transmission rods for connecting adjacent two right-angle steering gears.

[0008] Preferably, the electric clutch device includes a clutch bracket, on which a motor and a clutch are installed. One side of the clutch is connected to a first coupling, and the first coupling is connected to the right-angle steering gear. The motor drives the first coupling on the clutch to rotate.

Embodiment 1

[0025] The utility model realizes the unified control of the lifting of exhibits in multiple display cabinets by an external control platform through the setting of an electric clutch device 1, and a hand-operated clutch device 2 is arranged in each display cabinet to realize the control of the lifting of exhibits in a single display cabinet. It solves the problem that the existing display cabinets cannot simultaneously achieve unified control by an external control platform and single control.

[0026] As Figure 1 shown, a display cabinet clutch opening mechanism includes an electric clutch device 1, a hand-operated clutch device 2 and a steering mechanism 3 installed in the display cabinet. Both the electric clutch device 1 and the hand-operated clutch device 2 are connected to the steering mechanism 3. At least two moving devices 4 are connected to the steering mechanism 3, and the moving devices 4 are fixed to the movable structure in the display cabinet. The electric clutch device 1 and the hand-operated clutch device 2 respectively control the displacement of the moving devices 4 through the steering mechanism 3.

[0027] As Figure 2-3 shown, further, the steering mechanism 3 includes at least three right-angle steering gears 31 and a transmission rod 32 for connecting adjacent two right-angle steering gears 31.

[0028] Further, the moving device 4 includes a support plate 41 and a lead screw 42 rotatably connected to the support plate 41. A moving plate 43 is installed on the lead screw 42 through a thread. One end of the lead screw 42 is connected to the right-angle steering gear 31 through the setting of a second coupling 44.

[0029] Further, the hand-operated clutch device 2 includes a control box 21 and a hand crank 22 installed in the control box 21. The control box 21 is connected to the right-angle steering gear 31 through the setting of a third coupling 23, and the hand crank 22 drives the third coupling 23 to rotate.

[0030] As Figure 4As shown in the figure, further, the electric clutch device 1 includes a clutch bracket 11, on which a motor 12 and a clutch 13 are installed. One side of the clutch 13 is connected to a first coupling 14, and the first coupling 14 is connected to the right-angle steering gear 31. The motor 12 drives the first coupling 14 on the clutch 13 to rotate.

[0031] Further, the three right-angle steering gears 31 are respectively connected to two moving devices 4 and a hand-operated clutch device 2; the electric clutch device 1 is connected to one right-angle steering gear 31.

[0032] Working principle:

[0033] When using the electric clutch device 1 to drive and control the lifting of exhibits in multiple display cabinets, the motor 12 controls the rotation of the first coupling 14. The right-angle steering gear 31 transmits the kinetic energy of the motor 12 to the second coupling 44 through the first coupling 14. The rotation of the second coupling 44 drives the rotation of the lead screw 42, and the moving plate 43 displaces on the lead screw 42. The movable structure in the display cabinet fixed to the moving plate 43 also displaces accordingly. When the movable structure in the display cabinet is installed vertically, the movable structure in the display cabinet performs a lifting action.

[0034] When using the hand-operated clutch device 2 to drive and control the lifting of exhibits in multiple display cabinets, manually rotate the hand crank 22 to drive the rotation of the third coupling 23. The third coupling 23 transmits the kinetic energy to the transmission rod 32 through the right-angle steering gear 31. The transmission rod 32 then transmits the kinetic energy to the second coupling 44 through other right-angle steering gears 31. The rotation of the second coupling 44 drives the rotation of the lead screw 42, and the moving plate 43 displaces on the lead screw 42. The movable structure in the display cabinet fixed to the moving plate 43 also displaces accordingly. When the movable structure in the display cabinet is installed vertically, the movable structure in the display cabinet performs a lifting action.

[0035] In the electric clutch device 1 of the present invention, under heavy pressure, there is no phenomenon of large resistance and jamming during the opening and closing of the motor 12, and the mechanism moves smoothly without the phenomenon of falling. Removing the electric clutch device 1 can switch to the hand-operated opening device 2, which is convenient for single control of the lifting of exhibits in a single display cabinet.
