Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic latch control technology for aircraft oxygen systems, and particularly relates to an electromagnetic latch control device. Background Technology

[0002] Currently, the electromagnetic latch on the machine mainly uses a combination of torsion springs and rocker arms to achieve the unlocking and locking functions. However, due to the structural characteristics of the torsion spring, the torque will decrease after long-term use, resulting in the inability to unlock in time. Utility Model Content

[0003] This utility model provides an electromagnetic latch control device that combines a cylindrical spring and a linkage mechanism to improve the service life of the electromagnetic latch.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] An electromagnetic latch control device, the device comprising: an electromagnet 1, a piston rod 2, a spring 3, a pull rod 4, a rivet 5, a locking plate 6, a latch 7, a screw 8, a housing 9, and a stop bar 10; The electromagnet 1 is fixed to the housing 9 with screws through small holes at both ends; the spring 3 is fitted into one end of the smooth surface of the piston rod 2, and the smooth surface of the piston rod 2 passes through the through hole of the partition plate in the middle of the housing 9; the stop bar 10 is installed on the square column at one end of the piston rod 2 through the middle square hole, and a pull rod 4 is installed at each end of the stop bar 10. Two clips 6 are respectively placed into the slots at the other end of the pull rod 4, and screws 8 pass through the holes at the right angles of the clips 6 and are screwed into the corresponding threaded holes of the housing 9; the latch 7 is placed in the area formed by the semi-circular arcs of the two clips 6.

[0006] Furthermore, Adjust the height of screw 8 according to the height of pull rod 4 so that the clamping plate 6 and the stop bar 10 are on the same horizontal plane.

[0007] Furthermore, The card plate (6) is composed of two L-shaped structures, with notches set on the short sides of the two L-shaped structures.

[0008] Furthermore, The stop bar 10 and the pull rod 4 are fixed together by rivets 5.

[0009] Furthermore, The two clamping plates 6 are fixed in the slots of the pull rod 4 with rivets 5.

[0010] When electromagnet 1 is energized, it generates magnetic force. Under the action of magnetic force, piston rod 2 moves to the left, pulling stop bar 10 and pull rod 4 to the left, causing the locking plate 6 to rotate around screw 8. The gap between the two locking plates 6 increases, and the latch 7 unlocks. Conversely, when electromagnet 1 is not energized, piston rod 2 moves to the right under the action of spring 3, pushing stop bar 10 and pull rod 4 to move to the right, causing clamp plate 6 to rotate around screw 8, reducing the gap between the two clamp plates 6, and locking buckle 7 achieves the locking function.

[0011] The advantages of this invention are: the combination of a cylindrical spring and a pull rod mechanism reduces the short service life of the original torsion spring and improves the service life of the electromagnetic latch. Attached Figure Description

Detailed Implementation

[0013] The technical solution of the utility model will be described in detail below with reference to the accompanying drawings.

[0014] This utility model provides an electromagnetic latch control device that releases the latch when the power is turned on and locks the latch when the power is turned off.

[0015] like Figure 1 and Figure 2 As shown, it specifically includes: electromagnet 1, piston rod 2, spring 3, pull rod 4, rivet 5, clamping plate 6, latch 7, screw 8, housing 9, and stop bar 10.

[0016] Electromagnet 1 is fixed to housing 9 with screws through two small holes at both ends; spring 3 is fitted onto one end of the smooth surface of piston rod 2, and the smooth surface end of piston rod 2 passes through the through hole of the middle partition plate of housing 9; stop bar 10 is installed on the square column at one end of piston rod 2 through the middle square hole, and a pull rod 4 is installed at each end of stop bar 10 and fixed with rivets 5; two retaining plates 6 are respectively placed into the retaining grooves at the other end of pull rod 4 and fixed with rivets 5; screw 8 is passed through the hole at the right angle of retaining plate 6 and screwed into the corresponding threaded hole of housing 9, and the height of the screw is adjusted according to the height of the pull rod so that retaining plate 6 and stop bar 10 are on the same horizontal plane; the latch 7 is placed in the area formed by the semi-circular arc of the two retaining plates 6 (e.g., Figure 3(As shown).

[0017] When electromagnet 1 is energized, it generates magnetic force. Under the action of the magnetic force, piston rod 2 moves to the left, pulling stop bar 10 and pull rod 4 to the left, causing the locking plate 6 to rotate around screw 8. The gap between the two locking plates 6 increases, and latch 7 unlocks. Conversely, when electromagnet 1 is not energized, piston rod 2 moves to the right under the action of spring 3, pushing stop bar 10 and pull rod 4 to the right, causing locking plate 6 to rotate around screw 8. The gap between the two locking plates 6 decreases, and latch 7 locks.

[0018] The advantages of this invention are: the combination of a cylindrical spring and a pull rod mechanism reduces the short service life of the original torsion spring and improves the service life of the electromagnetic latch.
