Problems solved by technology

[0005] (1) Suction cups made of traditional materials have good adhesion to hard, flat and smooth target surfaces (such as window glass, iron doors of refrigerators, etc.), but for semi-flat surfaces (such as cement walls, painted but not Polished wooden doors, etc.) and uneven and relatively rough surfaces, the suction cups made of traditional materials cannot fit well with such surfaces, so that they cannot lock the air pressure difference inside and outside the suction cups, resulting in poor adsorption. Therefore, the suction cups are completely Can't stick to the target surface, or can only stay for one to two seconds and then quickly detach
This feature greatly limits the space for children to play with suction cup toys, and also limits the play value of children when they play
[0006] (2) Based on the above reasons, in addition to using more elastic traditional synthetic materials, toy manufacturers pay more attention to the structural improvement of the suction cup when designing the suction cup. Strong suction, but still not much help on less flat and rough surfaces
If it is projected at a small angle to the target surface, in most cases the suction cup toy can only bounce back from the target surface to the ground and cannot stick to the target surface, which limits the fun value when children play

Embodiment Construction

[0029] A suction cup head of a hand-thrown throwing toy of the present invention, the suction cup head is made of a soft foamed synthetic material, and the components of the soft foamed synthetic material include: 35%-45% polyvinyl acetate, 10%-20% % ethylene vinyl acetate, 10% to 20% nitrile rubber, 5% to 15% polyethylene, 15% to 25% calcium carbonate. In addition, appropriate amount of foaming agent, foam stabilizer, thermal stabilizer, and crosslinking agent are mixed with foaming molding under the action of catalyst. The soft foamed synthetic material made by this combination of ingredients and the appropriate foaming process has the characteristics of light weight, softness, elasticity, easy bending, and controllable weak air permeability, which are very important for the suction cup head. function is important. In addition, the cell diameter of the soft foamed synthetic material is less than 0.2 mm; the cell ratio of the soft foamed synthetic material is 5% to 10%.

Abstract

The invention discloses a chuck head of a hand-throwing toy and a chuck dart using same. The chuck is made of soft foaming composite material which has the following components: 35-45% of polyvinyl acetate, 10-20% of ethylene vinyl acetate, 10-20% of nitrile rubber, 5-15% of polyethylene and 15-25% of calcium carbonate; the invention also discloses a chuck dart using the chuck which provides more forceful guarantee for safety of children when playing; the dart can still stick to the chuck even if the surface thereof is relatively coarse; as a result, playing site and space for chuck-like toys is substantially expanded; the chuck can automatically comes off after sticking to the dart for a while, reducing dissatisfaction of parents; even if the dart is thrown at a very small angel, the chuck can still stick to the target dart, further increasing amusement.

Description

technical field [0001] The invention relates to a part of a hand-throwing toy, in particular to a suction cup head of a hand-cast throwing toy; the invention also relates to a suction cup dart applying the suction cup head. Background technique [0002] In the early twentieth century, suction cups made of natural rubber were first used in projectile toys. Toy darts and toy arrows with suction cups on the head have the following unique advantages: (1) The suction cup is like a large and blunt rubber arrow, and the toy darts with suction cups are not easy to hurt people when shooting, so they are relatively safe for playing. (2) Unlike other toys with a blunt head structure, toy darts or toy arrows with suction cups can be pasted on hard and smooth surfaces, so darts with suction cups are better than ordinary toys. Pure head toys can provide more and excellent play value to children playing, so they are widely used in toy products. [0003] In the early suction cup toys, the...
