The outer side walls of the hook 14 and the positioning hook 23 are coated with wear-resistant layers. The wear-resistant layer can reduce the abrasion loss of the clamping hook 14 and the positioning hook 23, so that the strength of the clamping hook 14 and the positioning hook 23 is improved.
The wear-resistant layer is composed of the following raw materials in percentage by mass:
the graphene has good toughness, and the toughness of the cured novolac epoxy resin can be enhanced after the graphene is added into the novolac epoxy resin, so that the wear resistance and the lubricity of the novolac epoxy resin are improved. The hardness of the silicon carbide powder is high, and the addition of the silicon carbide powder can improve the wear resistance of the wear-resistant layer. The tin powder can improve the strength of the wear-resistant layer, the effect of improving the strength of the wear-resistant layer cannot be achieved when the amount of the tin powder is small, and the enrichment tendency can occur when the amount of the tin powder is too large.
As shown in fig. 3, when the stroller brake device according to this embodiment is used without braking, the sliding rod 33 is elastically supported by the compression spring 34, the locking pin 3 does not contact with the locking hub 2, so that the wheels can freely rotate, and the stroller is in free running; meanwhile, the hook 14 and the pedal 13 are both in a flat state, and the hook end of the hook 14 is not in contact with the hook end of the positioning hook 23.
When the brake is needed, the pedal 13 is stepped by feet, the pedal rod 11 and the rotating shaft 12 are driven to rotate, the first connecting rod 36 and the second connecting rod 38 are driven by the rotating shaft 12 to drive the sliding rod 33 to slide downwards along the sliding groove 32 and insert into the locking groove 4 of the locking hub 2, and the locking hub 2 and the wheel are locked to prevent the rotation of the locking hub 2 and the wheel; meanwhile, the hook 14 is driven by the pedal 13 to rotate and passes over the hook end of the positioning hook 23, so that the hook end of the hook 14 is contacted with the hook end of the positioning hook 23; when the pedal 13 is released, the hook 14 is hooked by the positioning hook 23 and prevented from returning under the tension of the tension spring 27.
When the vehicle is braked and needs to go forward continuously, the reset pedal 24 is stepped down by feet to enable the positioning hook 23 to rotate until the hook 14 is separated from the limitation of the positioning hook 23, the straight position is restored under the action of the elastic force of the pressure spring 34, the slide rod 33 is also restored to the initial position, the limitation on the locking hub 2 is removed, and the wheel can rotate freely.
