[0022] As Figures 1 to 4 The utility model provides a lock catch for T type guide rod, including lower shell 1, one end of lower shell 1 is fixedly connected with upper shell 2, and upper shell 2 is equipped with lock catch assembly 9 jointly between lower shell 1,
[0023] Lock catch assembly 9 includes two buttons 6, and the two buttons 6 are installed at one end of upper shell 2 and lower shell 1 respectively, the two buttons 6 are fixedly connected with two clasp spring one 5 at corresponding end, and one end of two clasp spring one 5 of the same side is fixedly connected with limit pressing block 7, and one end of two limit pressing blocks 7 is slidably connected with lock block 3, the elastic connection of clasp spring one 5 makes button 6 can drive limit pressing block 7 accurately, and then control the sliding of lock block 3, make the unlocking and locking action more smooth, save the labor, and the top of lock block 3 is fixedly connected with cylinder 12 on both sides, and the inner surface of two cylinders 12 is slidably connected with vertical rod 13, and the top of vertical rod 13 is fixedly connected with slide plate 4, and the top of two slide plates 4 is fixedly connected with protruding block 10, and the side of lower shell 1 is provided with recess for using two protruding blocks 10, and the outer surface of two vertical rods 13 is around connected with clasp spring two 8, and the cooperation of cylinder 12, vertical rod 13 and clasp spring two 8 makes protruding block 10 can stably adapt with recess, on the one hand, the stability of lock catch in the locked state is enhanced, and on the other hand, reliable elastic force is provided for the reset after subsequent unlocking.
[0024] Specifically, the bottom end of the second clamp spring 8 is fixedly connected with the lower inner wall of the cylinder 12, and the top end of the second clamp spring 8 is fixedly connected with the bottom end of the sliding plate 4, so as to ensure that the elastic force of the second clamp spring 8 can stably act on the sliding plate 4 vertically, maintain the close degree of the protrusion 10 and the groove, and avoid affecting the locking performance due to installation deviation.
[0025] As shown in Figures 1 to 4 the upper shell 2 and the lower shell 1 are adaptively connected with each other, the adaptively connected upper and lower shells 1 are not only easy to assemble, but also can prevent too much external dust, water vapor and other impurities from entering the inside, protect the lock assembly 9 and prolong the service life.
