Technical Field

[0001] The utility model belongs to the technical field of plastic product processing, and more specifically, particularly relates to a fixing structure for detecting the heat resistance of plastic toys. Background Art

[0002] Plastic toys are toys made of plastic as the main raw material. According to the plastic molding process, they are divided into injection molded toys, blow molded toys, rotational molded toys, slush molded toys, inflatable toys, etc. Injection molded toys are made by heating the raw materials into liquid by an injection molding machine, injecting them into a mold and cooling them into shape. Blow molded toys are made by heating and squeezing the raw materials into a cylindrical semi-liquid state by an extruder, and then entering the split mold. After the mold is closed, it is inflated and formed, and cooled and fixed to become a rotational molded toy. Plastic toys need to be tested for heat resistance during production.

[0003] In toy testing, a fixing mechanism is needed to fix the toy. However, the existing fixing mechanism for toy testing can only clamp and fix plastic toys with relatively standard shapes. When clamping and fixing special-shaped toys, it is easy to cause unstable clamping and falling off during the clamping process, which is inconvenient to use. Therefore, in view of this, the existing structure and defects are studied and improved, and a fixing structure for plastic toy heat resistance performance testing is provided, in order to achieve a more practical purpose.

[0025] Among them, the driving mechanism includes a driving gear 8 installed inside the platform 1, and one side of the driving gear 8 is meshed and connected with four groups of driven gears 7. The top ends of the four groups of driven gears 7 are fixedly connected with driving columns 11, and the outer walls of the driving columns 11 are all covered with driving bars 9 for driving the connecting rod 2 to move.

[0027] Among them, the cross-section of the connecting rod 2 is L-shaped, and a sliding groove adapted to the connecting rod 2 is opened at the top of the platform 1. The bottom end of the connecting rod 2 passes through the sliding groove and is fixedly connected to the middle part of the top of the driving bar 9. By setting the sliding groove, a guiding role is played for the sliding of the connecting rod 2.
