Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and particularly to an embedded installation and movable distribution cabinet. Background Art

[0002] Distribution cabinets are divided into power distribution cabinets and lighting distribution cabinets, which are the end-level equipment of the power distribution system. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring and control for the loads, and plays an important role in actual production. For traditional embedded distribution cabinets, it is necessary to regularly repair and maintain the electrical components inside the device, and it is necessary to repeatedly disassemble and assemble the electrical components. Some structures have dead corners, which even cause the staff to install them insecurely, resulting in poor line contact, causing fires, or causing inconvenient installation and fixation.

[0014] In the present invention, the first slider drives the first movable bolt to slide, and at the same time the first movable bolt slides in the second movable groove. The first movable bolt gives a lateral thrust to the inner wall of the second movable groove. The first movable bolt pushes the swing rod to swing downward around the second movable bolt, and the swing rod drives the fixed pin to move downward.

[0023] As an embodiment of the present invention, as Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 9 and Figure 10 shown, the linkage mechanism 2 includes an integrated circuit board 21.

[0024] A second movable bolt 202 is rotatably connected to the bottom end of the swing rod 25. A first movable bolt 27 is slidably connected to the inner wall of the second movable groove 26. A first slider 28 is fixedly installed on the end face of the first movable bolt 27; the outer wall of the first slider 28 is slidably connected to a locking box 29, and a first telescopic spring 201 is fixedly installed on the inner wall of the locking box 29; During operation, the staff opens the cabinet door 11, holds the integrated circuit board 21 and pushes the integrated circuit board 21 along the first movable groove 22 into the inner wall of the base 1. The integrated circuit board 21 pushes the first slider 28, and the first slider 28 slides along the inner wall of the locking box 29. The first slider 28 compresses the first telescopic spring 201, and the first telescopic spring 201 deforms to store energy. The first slider 28 drives the first movable bolt 27. While the first movable bolt 27 slides along the second movable groove 26, the first movable bolt 27 slides in the second movable groove 26, and the first movable bolt 27 gives a thrust to the side wall of the second movable groove 26. The first movable bolt 27 pushes the swing rod 25 to swing around the second movable bolt 202, and the swing rod 25 drives the fixed pin 24 to move upward, so that the fixed pin 24 is disengaged from the limit hole 23, and the integrated circuit board 21 is unlocked from the base 1, thereby facilitating the staff to timely extract the integrated circuit board 21 from the base 1; The first slider 28 drives the first movable bolt 27 to slide.

A third movable groove 32 is slidably connected to the outer wall of the limiting pin 31. A second telescopic spring 33 is fixedly installed on the end face of the limiting pin 31; One end of the second telescopic spring 33 away from the limiting pin 31 is fixedly installed with a second slider 34. A ratchet 35 is rotatably connected to the end face of the second slider 34; A limiting pile 36 is slidably connected to the outer wall of the ratchet 35. A positioning bayonet 37 is fixedly installed on the surface of the limiting pile 36; During operation, the first telescopic spring 201 deforms to release energy. The first telescopic spring 201 pushes the first slider 28 to slide. The first slider 28 drives the limit pin 31 to slide. The limit pin 31 pushes the ratchet wheel 35, and the clamped ratchet wheel 35 slides. The ratchet wheel 35 slides along the third moving slot 32 and is clamped by the positioning bayonet 37, so that the positioning bayonet 37 restricts the continuous sliding of the first slider 28, positions the limiting mechanism 3, and further prevents the first slider 28 from driving the first movable bolt 27 to slide along the second moving slot 26. The second moving slot 26 drives the swing rod 25 to move. The swing rod 25 drives the fixed pin 24 to move downward. The fixed pin 24 is inserted into the limit hole 23, so that the fixed pin 24 and the limit hole 23 are kept in a disengaged state; The sliding of the first slider 28 drives the limit pin 31. The limit pin 31 slides along the third moving slot 32. The limit pin 31 pulls the second telescopic spring 33. The second telescopic spring 33 drives the second slider 34 to slide. The second slider 34 drives the ratchet wheel 35 to slide. The ratchet wheel 35 disengages from the limit pin 31. The ratchet wheel 35 contacts the limit post 36. The limit post 36 pushes the ratchet wheel 35 to rotate, so that the ratchet wheel 35 slides outward out of the limit of the limit post 36. The first telescopic spring 201 releases energy and deforms. The first telescopic spring 201 pushes the first slider 28 to slide. The first slider 28 drives the first movable bolt 27 to continue sliding along the second moving slot 26. The first slider 28 pushes the swing rod 25 to turn downward around the second movable bolt 202. Further, the swing rod 25 drives the fixed pin 24 to insert downward into the limit hole 23, keeping the fixed pin 24 and the limit hole 23 clamped, preventing the circuit board 21 from detaching from the base 1, and improving the stability of the device during operation; When the staff member pushes the circuit board assembly 21 again, the circuit board assembly 21 pushes the first slider 28. The first slider 28 drives the limit pin 31, and the limit pin 31 disengages from the ratchet wheel 35. The limit pin 31 drives the second telescopic spring 33 along the third moving slot 32, the second telescopic spring 33 drives the second slider 34, the second slider 34 drives the ratchet wheel 35, and the ratchet wheel 35 disengages from the positioning bayonet 37. At the same time, when the ratchet wheel 35 disengages from the positioning bayonet 37, the ratchet wheel 35 rotates. At this time, the ratchet teeth of the ratchet wheel 35 deflect. When the ratchet wheel 35 slides horizontally along the third moving slot 32 again, because the ratchet teeth of the ratchet wheel 35 deflect, the ratchet wheel 35 disengages from the positioning bayonet 37, causing the limit mechanism 3 to disengage from the restriction of the positioning bayonet 37. When the staff member releases the circuit board assembly 21, the first telescopic spring 201 releases energy again and deforms. The first telescopic spring 201 pushes the first slider 28, the first slider 28 drives the limit pin 31, and the limit pin 31 clamps the ratchet wheel 35 and pushes the ratchet wheel 35 to slide past the bottom of the positioning bayonet 37, so as to maximize the deformation of the first telescopic spring 201 and maximize the sliding stroke of the first slider 28 in the third moving slot 32. The greater the sliding stroke of the first slider 28 along the second moving slot 26, the greater the deflection angle of the swing rod 25 driven by the first slider 28 around the second movable pin 202, and the greater the insertion depth of the fixed pin 24 driven by the swing rod 25 in the limit hole 23, making the connection between the circuit board assembly 21 and the base 1 more firm.

[0026] Working principle: During operation, the staff member opens the cabinet door 11, holds the circuit board assembly 21 and pushes the circuit board assembly 21 along the first moving slot 22 into the inner wall of the base 1. The circuit board assembly 21 pushes the first slider 28, and the first slider 28 slides along the inner wall of the locking box 29. The first slider 28 compresses the first telescopic spring 201, and the first telescopic spring 201 deforms to store energy. The first slider 28 drives the first movable pin 27. While the first movable pin 27 slides along the second moving slot 26, the first movable pin 27 slides in the second moving slot 26, giving a thrust to the side wall of the second moving slot 26. The first movable pin 27 pushes the swing rod 25 to swing around the second movable pin 202, and the swing rod 25 drives the fixed pin 24 to move upward, so that the fixed pin 24 disengages from the limit hole 23, unlocking the circuit board assembly 21 from the base 1, and facilitating the staff member to extract the circuit board assembly 21 from the base 1 in a timely manner. During operation, the first telescopic spring 201 deforms to release energy. The first telescopic spring 201 pushes the first slider 28 to slide. The first slider 28 drives the limit pin 31 to slide. The limit pin 31 pushes the ratchet wheel 35, and the ratchet wheel 35 is clamped and slides. The ratchet wheel 35 slides along the third moving slot 32 and is clamped by the positioning bayonet 37, so that the positioning bayonet 37 restricts the first slider 28 from continuing to slide, positions the limiting mechanism 3, and further prevents the first slider 28 from driving the first movable bolt 27 to slide along the second moving slot 26. The second moving slot 26 drives the swing rod 25 to move. The swing rod 25 drives the fixing pin 24 to move downward. The fixing pin 24 is inserted into the limiting hole 23, so that the fixing pin 24 and the limiting hole 23 are kept disengaged; further prevents the first slider 28 from driving the first movable bolt 27 to slide along the second moving slot 26. The second moving slot 26 drives the swing rod 25 to move. The swing rod 25 drives the fixing pin 24 to move downward. The fixing pin 24 is inserted into the limiting hole 23, so that the fixing pin 24 and the limiting hole 23 are kept disengaged; The sliding of the first slider 28 drives the limit pin 31. The limit pin 31 slides along the third moving slot 32. The limit pin 31 pulls the second telescopic spring 33. The second telescopic spring 33 drives the second slider 34 to slide.

The limit post 36 pushes the ratchet wheel 35 to rotate, so that the ratchet wheel 35 slides outwards away from the limit of the limit post 36. The first telescopic spring 201 releases energy and deforms. The first telescopic spring 201 pushes the first slider 28 to slide. The first slider 28 drives the first movable bolt 27 to continue to slide along the second moving slot 26. The first slider 28 pushes the swing rod 25 to turn downward around the second movable bolt 202. Further, the swing rod 25 drives the fixing pin 24 to be inserted downward into the limiting hole 23, and keeps the fixing pin 24 and the limiting hole 23 clamped, avoiding the circuit board 21 from detaching from the base 1, and improving the working stability of the device; When the staff pushes the circuit board 21 again, the circuit board 21 pushes the first slider 28. The first slider 28 drives the limit pin 31. The limit pin 31 disengages from the ratchet wheel 35. The limit pin 31 drives the second telescopic spring 33 along the third moving slot 32. The second telescopic spring 33 drives the second slider 34. The second slider 34 drives the ratchet wheel 35. The ratchet wheel 35 disengages from the positioning bayonet 37. At the same time, when the ratchet wheel 35 disengages from the positioning bayonet 37, the ratchet wheel 35 rotates. At this time, the ratchet teeth of the ratchet wheel 35 deflect. When the ratchet wheel 35 slides horizontally along the third moving slot 32 again, because the ratchet teeth of the ratchet wheel 35 deflect, the ratchet wheel 35 disengages from the positioning bayonet 37, so that the limiting mechanism 3 is released from the restriction of the positioning bayonet 37; When the ratchet wheel 35 slides horizontally again along the third moving slot 32, due to the deflection of the ratchet teeth of the ratchet wheel 35, the ratchet wheel 35 disengages from the positioning bayonet 37, enabling the limiting mechanism 3 to be released from the restriction of the positioning bayonet 37; when the staff releases the integrated circuit board 21, the first telescopic spring 201 releases energy again and deforms. The first telescopic spring 201 pushes the first slider 28, and the first slider 28 drives the limit pin 31. The limit pin 31 clamps the ratchet wheel 35 and pushes the ratchet wheel 35 to slide past the bottom of the positioning bayonet 37, thereby maximizing the deformation of the first telescopic spring 201 and maximizing the sliding stroke of the first slider 28 in the third moving slot 32. The greater the sliding stroke of the first slider 28 along the second moving slot 26, the greater the angle by which the first slider 28 pushes the swing rod 25 to deflect around the second movable pin 202, and the greater the depth at which the swing rod 25 drives the fixed pin 24 to be inserted into the limit hole 23, making the connection between the integrated circuit board 21 and the base 1 more secure. The greater the sliding stroke of the first slider 28 along the second moving slot 26, the greater the angle by which the first slider 28 pushes the swing rod 25 to deflect around the second movable pin 202, and the greater the depth at which the swing rod 25 drives the fixed pin 24 to be inserted into the limit hole 23, making the connection between the integrated circuit board 21 and the base 1 more secure; The first slider 28 drives the first movable pin 27 to slide.
