Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the drawings:
[0037] figure 1 , figure 2 The first embodiment of the present invention is shown.
[0038]The durability testing machine for the adjustment mechanism of the infant dining chair includes a dining chair fixing bracket 10, an "I"-shaped plate 20, a large cylinder 30, two small cylinders 40, and an electrical control box 50. The dining chair fixing bracket 10 is composed of two mutually parallel brackets 11 fixed on the work surface 1. Each bracket 11 further includes a column frame 111 whose upper end is roughly "L" and another column frame 112 provided at a position corresponding to the column frame 111 on the work surface 1. The upper end of the column frame 111 is at an "L" shape and the column The upper end surface of the frame 112 is respectively provided with grooves 113 and 114 for placing the dining chair 2 for children. In addition, two corresponding through holes 1...

The invention relates to a child dinning chair adjusting mechanism durability tester and its testing method. It is composed of a main body, a large cylinder placed in the main body, piston rods extending out of the main body, a dining chair fixed bracket installed on the main body, an electric control box and a small cylinder installed on the fixed bracket. The test method: locking the dining chair in a groove on the fixed bracket; setting number of testing times; starting the tester, the piston rod of the large cylinder ascends to push the adjusting rod of the dinning chair adjusting mechanism to reach the locking position; a up travel sensor senses a sensing block on the large cylinder to transmit a signal to withdraw the piston, so as to drive the sensing block to descend to a down travel sensor; and at the same time, the piston rod of the small cylinder extends and presses the locking piece of the adjusting mechanism of the dinning chair, so as to make the above adjusting rod disengaged from the above locking piece and freely falls to a unlocking state; after the sensing block descends to the down travel sensor and is sensed, the scavenge valve of the large cylinder reverses the gas source to make the large cylinder ascend; according to the above steps, so reciprocating and circulating to detect fatigue resistance of the dinning chair adjusting mechanism.
Description
Technical field [0001] The invention relates to a testing machine and a testing method for testing the durability of a child dining chair adjustment mechanism that can be hung on or connected to a table or other objects. Background technique [0002] When the baby's parents need to eat in a restaurant or other places, if they eat while holding the child, it will cause a lot of inconvenience to the baby's parents, and the use of a dining chair can solve the above problems. Parents of infants can fix the dining chair next to the dining table, and then place the child in the dining chair. In this way, the parent of the infant can take care of the child and facilitate the meal. In order to prevent the dining chair from falling off the dining table, the general dining chair is equipped with a holding frame (card holder) so that the dining chair can be more firmly clamped on the dining table; and to further increase the safety of the dining chair, some dining chairs have another Instal...
