[0016] Bidirectional electric push rod 1, seamless tube 2, pin head 3, locking seat 4, cotter pin 5, pin shaft 6, connecting rod male head 7, nut sleeve 8, connecting rod female head 9, hexagonal nut 10, copper sleeve 11. DETAILED DESCRIPTION
[0017] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.
[0018] like Figure 1-Figure 4 As shown, this specific embodiment adopts the following technical solution: it includes a bidirectional electric push rod 1, a seamless tube 2, a latch head 3 and a locking seat 4; the locking seat 4 is two, upper and lower, respectively fixed on the upper and lower sides of the inner side of the door leaf; the bidirectional electric push rod 1 is fixed on the inner side of the door leaf, and the bidirectional electric push rod 1 has its own limit sensor, one of the output ends of the bidirectional electric push rod 1 is connected to the latch head 3 using the seamless tube 2, and the other output end is connected to the latch head 3 using the cotter pin 5 and the pin shaft 6 (the outer diameter of the latch head 3 is larger than the outer diameter of the latch head currently on the market); the upper and lower latch heads 3 are respectively movably inserted in the copper sleeves 11 in the upper and lower locking seats 4.
[0019] Preferably, the lower end of the seamless tube 2 is connected to a connecting rod male head 7 by means of a nut sleeve 8, and the connecting rod male head 7 is connected to the upper output end of the bidirectional electric push rod 1 by means of a pin shaft; the nut sleeve 8 is fixed on the upper and lower ends of the seamless tube 2, and the connecting rod male head 7 and the connecting rod female head 9 are respectively threadedly connected to the upper and lower nut sleeves 8; a hexagonal nut 10 is provided on the end of the nut sleeve 8 away from the seamless tube 2, and the hexagonal nut 10 is threadedly connected to the connecting rod female head 9 and the connecting rod male head 7; the connecting rod female head 9 is connected to the lower end of the pin head 3 by means of a pin shaft.
[0020] When using the utility model, the bidirectional electric push rod 1 is used to drive the closing and disengagement between the upper and lower latch heads 3 and the locking seat 4 to achieve opening and closing; when the power is off, an electric wrench can be used manually to align the external hexagonal screw tail shaft at the tail of the bidirectional electric push rod 1 to achieve manual opening of the latch shaft 3 (the torque of the electric wrench is about 500-800NM, the speed is adjustable, and the test effect can be completed in about 40 seconds).
