Description

Safe type sport skateboard

Technical Field

The invention belongs to the field of sports equipment, and particularly relates to a safe sports skateboard.

Background

The skateboard project is a nasal ancestor of the extreme exercise history, and a plurality of extreme exercise projects are extended from the skateboard project. The skateboard developed by surfing in the late 50 s and early 60 s of the 20 th century is widely pursued and loved by young people and is the most cool sport on the earth nowadays due to the advantages of simplicity, easy learning, convenient carrying and low place limitation.

The existing skateboard is mostly composed of a board and two groups of pulleys and does not have an emergency brake function, most users can lean back when emergency brake is needed in the sliding process, and then put down one foot to rub with the ground, so that the skateboard is decelerated, the abrasion of shoes is serious, and the operation is very dangerous for beginners and is very easy to fall down due to unstable gravity center; when the skateboard is accelerated, the body of a user leans forward, the sole of the user forcibly treads the skateboard to accelerate, and the skateboard is smooth in surface, so that the dangerous safety that the skateboard is easy to slip is low.

To this end, we propose a safety sport skateboard to solve the above problems.

Disclosure of Invention

The invention aims to provide a safe sports skateboard convenient for braking, aiming at the problems that the braking operation is difficult and the skateboard is easy to slip.

In order to achieve the purpose, the invention adopts the following technical scheme: a safety type sport skateboard comprises a skateboard body, wherein the lower end of the skateboard body is fixedly connected with a front bearing block through an air bag, a front wheel is arranged on the front bearing block, a cavity is formed in the skateboard body and is communicated with the air bag, a piston plate is connected to the side wall of the cavity in a sealing and sliding mode, the upper end of the piston plate is fixedly connected with the side wall of the cavity through a first spring, a plurality of anti-skidding blocks are fixedly connected to the upper end of the piston plate, and the upper ends of the anti-skidding blocks penetrate through the skateboard body;

the utility model discloses a bearing block, including plate body, back bearing block, pivot, the lower extreme fixedly connected with gag lever post of plate body, the lower extreme of gag lever post extends to and sets up in the back bearing block.

In the above-mentioned safe type sport skateboard, the lower extreme fixedly connected with two telescopic links of plate body, the lower extreme and the preceding bearing block fixed connection of telescopic link.

In the safety sport skateboard, the upper end of the anti-skid block is arranged in an arc shape.

In the above-mentioned safe type sport skateboard, the lower extreme fixedly connected with brake block of gag lever post, the lower extreme of brake block is the sunken form of cambered surface shape and sets up.

In the above-mentioned safe type sport skateboard, the pivot overcoat is equipped with the gear, the lower extreme fixedly connected with brake strip of gag lever post.

Compared with the prior art, the safe type sport skateboard has the advantages that:

1. when the slide stops, the user can lean on backward, the focus shifts to the first half of the slide, the second spring is compressed, the limiting rod drives the brake block to move downwards and contacts with the rotating shaft, the limiting effect is achieved on the rotation of the rear wheel, the slide is easily stopped, the safety is high, the second spring plays a damping role, and the sliding experience is comfortable.

2. When the skateboard accelerates, the body of a user can lean forward, the center of gravity shifts to the front half part of the skateboard, the air bag is compressed, air in the air bag enters the cavity to push the anti-skid block out of the upper part of the skateboard body, the static friction force between the skateboard body and the sole of the user is increased, and the user is prevented from slipping down due to forcibly treading the skateboard body when accelerating.

3. When slide the place ahead meets barrier or dangerous condition and needs scram, the user health is faced backwards, and focus skew to slide the latter half, and the second spring is compressed, and the gag lever post drives the brake bar and moves down, and during the brake bar card went into the tooth's socket of gear, the compulsory rear wheel stall of driving, can effectually avoid dangerous the emergence.
