The mechanisms in the present embodiment will be described in detail below with reference to the drawings.
Referring to fig. 2 to 12, the clamping mechanism 20 includes a striker 21 and elastic jaws 22 fixedly mounted on both sides of the striker.
Referring to fig. 7 and 8, the striker 21 includes a striker mounting portion 211, a striker main body portion 212 fixed to the striker mounting portion, and a striker end portion 213 fixed to an end of the striker main body portion, a hollow through hole 2131 is provided in the striker end portion 213, and a width of the through hole 2131 is greater than a width of the elastic arm 14 'of the elastic buckle 10'.
Referring to fig. 10 and 11, the elastic jaw 22 includes a jaw body 221 fixedly mounted on the striker, a jaw connecting portion 222 fixed on the jaw body, and two jaw holding portions 223 fixedly mounted on the jaw connecting portion, and a distance between the two jaw holding portions 223 is greater than a width of the elastic arm 14 'of the elastic buckle 10'.
Specifically, the striker mounting portion 211 is fixedly mounted on a side surface of the connecting block 53 by a bolt or the like, the two elastic claws 22 are symmetrically mounted at lower ends of two sides of the striker body portion 212, the elastic claws 22 are symmetrically distributed along the striker end 213, and the lower end of the striker end 23 is disposed outside the elastic claws 22 in a protruding manner.
Preferably, the distance between the jaw connecting portion 222 and the striker end 213 in this embodiment gradually decreases from the end connected to the jaw body portion 221 to the end connected to the jaw holding portion 223; the jaw clamping portion 223 protrudes outward, and the distance between the jaw clamping portion 223 and the striker end 213 gradually increases and then gradually decreases from the end connected to the jaw connecting portion 222 to the end away from the jaw connecting portion 222.
The clamping principle of the clamping mechanism 20 in this embodiment is as follows:
referring to fig. 7 and 8 in combination with fig. 12, first, the striker end 213 and the elastic clamping jaw 22 are aligned with the opening of the elastic buckle 10 ', the elastic buckle 10' is fixed, the clamping mechanism 20 is driven to move downward, and the striker end 213 and the two elastic clamping jaws 22 are driven to be inserted between the side walls 12 'of the elastic buckle 10'.
During downward insertion, the striker end 213 abuts against the elastic arm 14 ', the thickness of the striker end 213 is greater than the distance between the two elastic arms 14 ' in the natural state, because the elastic arm 14 ' has elasticity, the elastic arm 14 ' is pushed outwards during the downward movement of the striker end 213, the third elastic arm 143 ' of the elastic buckle 10 ' is bent outwards along the receiving hole 1201 ', and finally the striker end 213 moves to abut against the bottom wall 11 ', and at this time, the elastic arm 14 ' is partially received in the through hole 2131 of the striker end 213.
The jaw clamping portion 223 of the elastic jaw 22 first contacts with the second sidewall 122 ' of the elastic buckle 10 ', and because the jaw clamping portion 223 has a certain elasticity, the jaw clamping portion 223 bends inward when continuing to move downward until the jaw clamping portion 223 abuts against the first sidewall 121 ' along the third sidewall 123 ', and at this time, the jaw connecting portion 222 abuts against the second sidewall 122 ', and finally the clamped state is shown in fig. 12.
After the clamping mechanism 20 clamps the elastic buckle 10 ', the assembly between the elastic buckle 10 ' and the hole on the panel can be integrally realized, and two sides of the hole are respectively clamped in the mounting grooves 1202 ' on two sides of the elastic buckle.
After the elastic buckle 10 'is installed, since the installation groove 1202' of the elastic buckle 10 'is relatively fixed to the hole on the panel, the clamping mechanism 20 is pulled out upward to separate the clamping mechanism 20 from the elastic buckle 10'.
During the separation process, the jaw connecting portion 222 and the jaw holding portion 223 of the elastic jaw 22 are bent inward, the jaw connecting portion 222 moves upward along the second sidewall 122 ', the jaw holding portion 223 moves upward along the first sidewall 121', the third sidewall 123 'and the second sidewall 122', and finally the elastic jaw 22 is separated from the sidewall of the elastic buckle.
When the striker end 213 moves upward, the first elastic arm 141 ', the second elastic arm 142 ', and the third elastic arm 143 ' are bent, so that the elastic arm 14 ' is separated from the through hole 2131 of the striker end 213, and the striker end 213 is separated from the elastic arm 14 '.
Preferably, in this embodiment, the width of the through hole 2131 is equivalent to the width of the junction between the first elastic arm 141 ' and the second elastic arm 142 ', and when the junction between the first elastic arm 141 ' and the second elastic arm 142 ' is received in the through hole 2131, the through hole 2131 can limit the elastic buckle 10 ' in the left-right direction.
Further, an inclined transition surface is provided between the through hole 2131 and the striker end 213 to enable mutual movement between the resilient arm 14' and the striker end 213.
