[0015] 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.
[0016] See also Figure 1-3The utility model provides the following technical solutions: an X-direction split armrest locking structure, comprising a button 1, a conversion pressure block 3, two lock hooks 4, an axle pin 6 and two reset torsion springs 7, a horizontal transmission shaft 11 is arranged on the button 1, the front of the transmission shaft 11 contacts the upper part of the conversion pressure block 3, the conversion pressure block 3 is arranged in a vertical direction and is perpendicular to the transmission shaft 11, after the button 1 is pressed in the X direction, the transmission shaft 11 is displaced in the X direction to push the conversion pressure block 3 to move downward in the Z direction, the two lock hooks 4 are connected in parallel on the left and right sides and the bottoms of the two lock hooks 4 are connected by the axle pin 6 penetrates through, a pressure rod 41 is provided on the rear side of the lock hook 4, two return torsion springs 7 are sleeved on the pressure rod 41 in the middle, and sleeved on the shaft pin 6 on both sides, the two sides of the middle part of the conversion pressure block 3 are in contact with the two pressure rods 41, and after the conversion pressure block 3 moves downward in the Z direction, the middle part of the conversion pressure block 3 presses on the left and right pressure rods 41 at the same time, and the pressure rods 41 are pressed down by force at the same time to make the left and right lock hooks 4 rotate, at this time the shaft pin 6 also rotates synchronously in the same direction, the return torsion spring 7 is twisted to generate a rebound force, and when the lock hook 4 rotates out of the handrail, the split handrail is unlocked.
[0017] Specifically, the upper part of the conversion pressure block 3 is in contact with the front part of the transmission shaft 11 at a 45° inclined surface. The transmission shaft 11 moves forward to push the conversion pressure block 3 downward, converting the X-direction movement into the Z-direction movement, reducing the positive X-direction space occupied by the lock hook 4. The lower middle part of the conversion pressure block 3 is cross-shaped and the lower part of the conversion pressure block 3 is located between the pressure rods 41 of the two lock hooks 4. Bumps 31 are provided under both sides of the middle part of the conversion pressure block 3. The bumps 31 are in contact with the pressure rod 41. The downward movement of the conversion pressure block 3 causes the bumps 31 to press the pressure rod 41, and the pressure rod 41 rotates.
[0018] Specifically, the lower middle portion of the conversion pressure block 3 is connected to the lock base 5, the upper portion of the lock base 5 is provided with a button groove 51, the button 1 is installed in the button groove 51, the lower middle portions of the two lock hooks 4 and the lower middle portion of the conversion pressure block 3 are both located at the lower portion of the lock base 5, the lower portion of the lock base 5 is provided with a rotating shaft groove 52, and both ends of the shaft pin 6 are located in the rotating shaft groove 52.
[0019] Specifically, a plurality of guide ribs 53 adapted to the middle portion of the conversion pressure block 3 are provided at the lower portion of the lock base 5. The guide ribs 53 are in contact with the front and rear sides of the middle portion of the conversion pressure block 3. The guide ribs 53 ensure that the conversion pressure block 3 does not shake left and right during the downward movement, so that the protrusion 31 on the conversion pressure block 3 presses down the pressure rod 41 synchronously.
[0020] Specifically, a button compression spring 2 is fixedly sleeved on the transmission shaft 11 , and when the button 1 is released, the button compression spring 2 returns the button 1 to its original position.
[0021] The motion process of the utility model is as follows: Figure 5When it is necessary to unlock the split armrest, first press the button 1 in the X direction, and the transmission rod 11 on the button 1 moves in the X direction to push the upper part of the conversion pressure block 3, and the conversion pressure block 3 moves downward to convert the X-direction movement into the Z-direction movement. At this time, the button compression spring 2 is compressed to generate a rebound force, and then the two protrusions 31 on the conversion pressure block 3 synchronously press down the two pressure rods 41, so that the lock hook 4 and the shaft pin 6 rotate synchronously. At this time, the reset torsion spring 7 is also twisted to generate a rebound force, and the button 1 is continued to be pressed, and the lock hook 4 continues to rotate and synchronously disengages from the split armrest, and the split armrest is synchronously unlocked. After releasing the button 1, the button 1 returns to its original position under the action of the button compression spring 2, and the lock hook 4 returns to its original position under the action of the reset torsion spring 7; Figure 4 When the split armrest needs to be closed, the two armrests only need to be pressed toward the middle to close, and at this time, the two lock hooks 4 buckle the two armrests under the action of the two reset torsion springs 7. The utility model does not need to limit the locking direction of the lock hook 4, does not destroy the original shape of the armrest, and is very clever and convenient.
