[0043] By rotating the worm 301b, the worm 301b rotates and engages with the turbine 301c to rotate the turbine 301c. The rotation of the turbine 301c drives the connecting rod 302a to rotate. The rotation of the connecting rod 302a drives the second pulley 202e to rotate.

[0044] Specifically, the outer side of the driving rod 301a is sleeved with a support frame 302b.

[0045] The support frame 302b is used to support the driving rod 301a.

[0046] Specifically, a rotating spring 302c is sleeved on the outside of the driving rod 301a, and a supporting shell 302d is sleeved on the outside of the rotating spring 302c. One end of the rotating spring 302c is fixed to one side of the driving rod 301a, and the other end is fixed to the inner wall of the supporting shell 302d.

[0047] The supporting shell 302d is used to support the rotation spring 302c.

[0048] When the protective door 102 needs to be opened, the driving rod 301a is rotated, and the driving rod 301a applies pressure to the rotation spring 302c. When the protective door 102 needs to be closed, the driving rod 301a is released, and the protective door 102 returns to its original position due to the rebound force of the rotation spring 302c.

[0049] Example 3

[0050] Reference Figure 5-Figure 6, which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0051] Specifically, a ratchet 302e is provided at one end of the driving rod 301a, and a pawl 302f is provided on one side of the ratchet 302e.

[0052] By rotating the ratchet 302e, the ratchet 302e drives the drive rod 301a to rotate, and the rotation of the drive rod 301a applies pressure to the rotation spring 302c. When the protective door 102 is opened to the desired position and needs to be limited, the pawl 302f is released, so that the pawl 302f and the ratchet 302e are re-engaged, thereby limiting the protective door 102.

[0053] Specifically, a support shaft 302g is inserted into the inner wall of the pawl 302f, and a placement plate 302h is provided on one side of the support shaft 302g. A torsion spring 302i is provided on the outer side of the support shaft 302g. One end of the torsion spring 302i is fixed to one end of the pawl 302f, and the other end is fixed to one end of the placement plate 302h. A handle 302j is also provided at one end of the driving rod 301a.

[0054] The support shaft 302g is used to support the pawl 302f, and the placement plate 302h is used to support the support shaft 302g.

[0055] When the pawl 302f is opened, the pawl 302f exerts pressure on the torsion spring 302i, and the pawl 302f is separated from the ratchet 302e. Then, the handle 302j is turned, and the rotation of the handle 302j drives the ratchet 302e to rotate. The rotation of the ratchet 302e drives the driving rod 301a to rotate, and the rotation of the driving rod 301a exerts pressure on the rotation spring 302c. The protective door 102 is opened by rotating the driving rod 301a. After it is opened to the desired position, the pawl 302f is released. At this time, the rebound force of the torsion spring 302i causes the pawl 302f to engage with the ratchet 302e, thereby limiting the position. Then, when the protective door 102 needs to be closed, the pawl 302f is pushed again to separate the pawl 302f from the ratchet 302e. At this time, the rebound force of the rotation spring 302c can cause the driving rod 301a to reverse, thereby closing the protective door 102.

[0056] Specifically, a protective frame 302k is provided on the outer side of the driving rod 301a.

[0057] The protection frame 302k is used to protect the driving rod 301a.

[0058] Specifically, it also includes a main body component 100, including a detection machine body 101, a protective door 102 and an operation panel 103. The protective door 102 is arranged at the top of the detection machine body 101, the detection machine body 101 is arranged at the bottom of the protective door 102, the operation panel 103 is arranged on one side of the detection machine body 101, the support plate 201a is arranged at the bottom of the protective door 102, the fixing plate 201b is arranged at one end of the protective door 102, one end of the support shell 302d is fixed to one end of the detection machine body 101, the other end of the protective frame 302k is fixed to one end of the detection machine body 101, and the other end of the placement plate 302h is fixed to one end of the operation panel 103.

[0059] The detector body 101 is a device used to monitor and identify whether an abnormal condition occurs in a device or system. The protective door 102 is used to prevent the operator from accidentally contacting dangerous parts inside the device. The operation panel 103 can be used to set various parameters of the fault detection device.

[0060] Two groups of support plates 201a and fixed plates 201b are provided. A connecting shaft is provided at one end of the fourth rotating rod 201f, and the other end of the connecting shaft is provided at one end of another fourth rotating rod 201f.

[0061] When in use, when the protective door 102 needs to be opened, the pawl 302f is first toggled, and the pawl 302f will apply pressure to the torsion spring 302i. At this time, the pawl 302f will separate from the ratchet 302e, and then the handle 302j is turned. The rotation of the handle 302j drives the ratchet 302e to rotate, and the rotation of the ratchet 302e drives the driving rod 301a to rotate. The rotation of the driving rod 301a applies pressure to the torsion spring 302c. The rotation of the driving rod 301a will also drive the worm rod 301b to rotate. The rotation of the worm rod 301b engages with the turbine 301c to rotate the turbine 301c. The rotation of the turbine 301c drives the connecting rod 302a to rotate. The rotation of the connecting rod 302a drives the second pulley 202e to rotate. The rotation of the second pulley 202e drives the belt 202d to rotate. The rotation of the belt 202d drives the first pulley 202c to rotate. The first pulley 202c rotates The fourth rotating rod 201f is driven to rotate, and the fourth rotating rod 201f rotates to drive the connecting plate 202b to move. The movement of the connecting plate 202b drives the second rotating rod 201d to move. The movement of the second rotating rod 201d drives the support plate 201a to move. When the connecting plate 202b moves, it also drives the first rotating rod 201c to move. The movement of the first rotating rod 201c drives the bending plate 202a to move. When the fourth rotating rod 201f rotates, it also drives the connecting shaft to rotate. The rotation of the connecting shaft drives the other end to drive the fourth rotating rod 201f to rotate. The movement of the support plate 201a can drive the protective door 102 to open. After opening to the required position, it needs to be limited. First, release the pawl 302f. At this time, the rebound force of the torsion spring 302i causes the pawl 302f to re-engage with the ratchet 302e, thereby limiting the protective door 102.

[0062] When the protective door 102 needs to return to its original position, the pawl 302f is moved again to separate the pawl 302f from the ratchet 302e. At this time, the rebound force of the rotation spring 302c causes the driving rod 301a to reverse, and the rotation of the driving rod 301a can drive the protective door 102 to close.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
