SUMMARY

[0003] The utility model wants to solve the technical problem that provides a kind of control cabinet rack door open detection mechanism, which is pressed to touch switch when cabinet door is opened, so that touch switch generates electric signal feedback.

[0004] In order to solve the above technical problems, the present application is realized by the following technical scheme: a control cabinet rack door open detection mechanism, including rack main body, cabinet door, rotating shaft, ball bearing, rotating disc, protective sleeve, touch switch and control module, the retainer of ball bearing is fixedly installed on rack main body, the upper and lower ends of rotating shaft are fixedly installed in the rotating body of ball bearing, the protective sleeve is fixedly installed at the bottom of rack main body, the accommodating area is provided in the protective sleeve, the touch switch is fixedly installed on the top wall of accommodating area, the rotating disc center position is provided with through -hole, the rotating disc through -hole is fixedly sleeved and installed at the bottom of rotating shaft, the rotating disc top surface is provided with the switch contact of annular convex structure, the switch contact has gap, the contact of touch switch is located in the gap after cabinet door is completely closed, the touch switch is connected to control module by circuit.

[0005] Preferably, the contact of the touch switch is provided as a spherical surface structure.

[0006] Preferably, the switch contact two ends are provided as slope structure.

[0007] Preferably, the lower end of the rotating shaft is rotatably installed in the bottom wall of the accommodating area.

[0008] Compared with the prior art, the detection mechanism drives the rotating shaft and the rotating disc to rotate synchronously with the cabinet door, and the switch contacts on the rotating disc can realize the pressing of the button of the touch switch to generate an electrical signal and feedback to the background monitoring terminal under the condition that the cabinet door is opened at any angle, and the switch contacts do not press the button of the touch switch when the cabinet door is closed, so that the pressing of the button of the touch switch is reduced, the service life of the button of the touch switch is prolonged, and the reliability of the touch switch is ensured. BRIEF DESCRIPTION OF DRAWINGS

[0009] The utility model is further described below in combination with the drawings.

[0010] Figure 1 It is the front view of the utility model.

[0011] Figure 2 It is Figure 1 the enlarged structural schematic diagram of M.

[0012] Figure 3 It is the structural schematic diagram of the rotating disc. DETAILED DESCRIPTION

[0013] The utility model is described in detail below in combination with the specific embodiment:

[0014] As Figures 1 to 3 indicated in a kind of control cabinet rack door detection mechanism, including rack main body 1, cabinet door 11, rotating shaft 2, ball bearing 21, rotating disc 3, protective sleeve 4, touch switch 5 and control module, the retainer of ball bearing 21 is fixedly installed on rack main body 1, the upper and lower ends of rotating shaft 2 are fixedly installed in the rotating body of ball bearing, protective sleeve 4 is fixedly installed at the bottom of rack main body 1, the accommodating area 41 is provided in protective sleeve 4, touch switch 5 is fixedly installed on the top wall of accommodating area 41, the through hole 33 of rotating disc 3 center position is provided with, the through hole 33 of rotating disc 3 is fixedly sleeved and installed at the bottom of rotating shaft 2, the rotating disc 3 top is provided with the switch contact 31 of annular protruding structure, the switch contact 31 has notch 32, the contact of touch switch 5 is located in notch 32 after cabinet door 11 is completely closed, touch switch 5 is connected to control module by circuit.

[0015] The contact of touch switch 5 is provided as spherical surface structure, the both ends of switch contact 31 are provided as slope structure, can avoid the contact of touch switch 5 and the both ends of switch contact 31 contact and appear obstruction problem, make the contact of touch switch 5 and switch contact 31 more smooth contact.

[0016] The lower end of the rotating shaft 2 is rotatably installed in the bottom wall of the accommodating area 41, which can increase the structural strength of the lower end of the rotating shaft 2, avoid the bending deformation of the rotating shaft 2 in long-term use, and prolong the service life.

[0017] When the cabinet door 11 is opened, the rotating shaft 2 and the rotating disc 3 rotate synchronously with the cabinet door 11, the switch contact 31 on the rotating disc 3 presses the button of the touch switch 5, the touch switch 5 generates an electric signal to the shaft control module, the control module sends a signal to the background monitoring terminal through the signal transceiver, and the background monitoring terminal displays that the cabinet door 11 is in an open state. When the cabinet door 11 is opened, the rotating shaft 2 and the rotating disc 3 rotate synchronously with the cabinet door 11, the switch contact 31 is separated from the button of the touch switch 5, and the button of the touch switch 5 rebounds in the gap 32. At this time, no electric signal is fed back to the control module, and the background monitoring terminal displays that the cabinet door 11 is in a closed state.
