Detailed Embodiments

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figures 1 to 4 The device for quickly removing the cable tie of an aircraft shown in the figure comprises a base 106, a push rod 104 and a return spring 108. A guide hole 109 is provided on the base 106 along its length direction. An unlocking plug 101 is also provided at the lower end of the base 106. The push rod 104 is passed through the guide hole 109 and both ends of the push rod 104 pass through the guide hole 109. A pin 105 is provided at the lower end of the push rod 104. The pin 105 can move relative to the base 106 with the push rod 104. Under normal circumstances, the pin 105 is locked. The length of the unlocking plug 101 along the axial direction does not exceed that of the unlocking plug 101. The reset spring 108 is sleeved on the push rod 104 and is always under compression, that is, the reset spring 108 always exerts a force on the push rod 104, so that the push rod 104 / thrust pin 105 always has a tendency to move from bottom to top along the axial direction, that is, the thrust pin 105 always has a tendency to move away from the unlocking plug 101 along the axial direction. When in use, the unlocking plug 101 is aligned with the lock buckle 203 in the lock hole 204 of the locking head 201 and the head end 202 of the cable tie. The person holds the base 106 and inserts the unlocking insert 101 into the gap between the lock buckle 203 and the cable tie head end 202, and the lock buckle 203 is squeezed and deformed to separate from the latch teeth (not shown) on the surface of the cable tie. If the deformation of the lock buckle 203 is not enough to separate it from the latch teeth, the person can drive the unlocking insert 101 to deviate away from the cable tie head end 202, use the lever to pry the lock buckle 203 away and press the lock buckle 203 downward to separate it from the latch teeth, so that the cable tie head end 202 can be relatively locked with the lock head 203. 01 moves, but because the unlocking plug 101 is inserted and increases the friction between the cable tie and the inner wall of the lock hole 204 / the unlocking plug 101, at this time, the push rod 104 is manually driven to move relative to the base 106, and the ejector pin 105 is able to press the cable tie head end 202, thereby forcing the cable tie head end 202 to escape from the lock hole 204, thereby realizing the function of quick removal; during operation, the unlocking plug 101 and the ejector pin 105 will not contact the surface of the aircraft wiring harness, thereby avoiding the risk of damaging the wiring harness, which is safe, reliable and easy to operate.

[0021] In some possible embodiments, reference Figure 2 and Figure 3As shown, an opening slot 110 is provided at the middle position of the base 106. The opening slot 110 enables the push rod 104 to be exposed outside the base 106. A limiting platform 107 is provided at one end of the push rod 104 located in the opening slot 110. The outer diameter of the limiting platform 107 is larger than the aperture of the guiding through hole 109 to prevent it from being able to escape from the guiding through hole 109 from bottom to top. The return spring 108 is sleeved on the part of the push rod 104 located in the opening slot 110, and one end of the return spring 108 is pressed against the lower side wall of the opening slot 110, and the other end is pressed against the limiting platform 107, so that the push rod 104 always has a tendency to move from bottom to top but cannot escape from the guiding through hole 109.

[0022] In some possible embodiments, referring to Figure 1 With Figure 2 As shown, it further includes a housing 102. The housing 102 covers the outer surface of the base 106 to cover the push rod 104 and the return spring 108, and is convenient for manual handling. The unlocking insert 101 protrudes from the lower end of the housing 102 to ensure that the unlocking insert 101 can be inserted into the lock hole 204.

[0023] In some possible embodiments, referring to Figure 1 With Figure 3 As shown, the unlocking insert 101 is in the shape of a V-shaped sheet with a gradually decreasing thickness to ensure that it can be accurately inserted into the gap between the lock catch 203 and the head end 202 of the tie. The tip of the unlocking insert 101 is rounded to prevent the tip of the unlocking insert 101 from damaging the surface of the wire harness during misoperation.

[0024] In some possible embodiments, referring to Figure 1 As shown, the cross-section of the ejector pin 105 is rectangular, aiming to increase the contact area between the ejector pin 105 and the head end 202 of the tie to ensure that the ejector pin 105 can eject the head end 202 of the tie out of the lock hole 204.

[0025] In some possible embodiments, referring to Figures 1 to 3 As shown, the upper end of the push rod 104 extends outside the housing 102, and a pressing cap 103 is provided at the upper end of the push rod 104 to facilitate manual driving of the push rod 104 to move axially relative to the base 106.
