The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Please refer to Fig.1-Fig. 4, in embodiment, a kind of wheel with speed limit brake function, including wheel seat 1, runner 2 and from
Dynamic braking mechanism 3, the runner 2 are installed on the wheel seat 1 by shaft 4；The automatic brake mechanism 3 is used for when wheel turns
When speed is too fast, wheel is braked automatically.
The automatic brake mechanism 3 includes sliding block 31, elastic component, wheel cap 32 and tooth lid 33, and the wheel cap 32 is fixedly installed
On the side of the runner 2 and positioned at the side of the shaft 4, the sliding block 31 and the elastic component are placed in the wheel cap
In 32, the sliding block 31 includes limiting section 312 and holding section 311, and the elastic component is set on the holding section 311, this reality
Apply in example, the elastic component is spring 34, is provided with the 32 corresponding position of wheel cap for stretching out the holding section 311
Opening, the tooth lid 33 is fixedly connected with the wheel seat 1, and the tooth lid 33 is equipped with interior ratchet structure 3311, when the engaging
When the opening is stretched out in portion 311, the holding section 311 engages with the interior ratchet structure 3311.
The present embodiment in use, when the runner 2 rotates, can drive wheel cap 32 and sliding block therein 31 to turn together
Dynamic, when reaching certain rotating speed, sliding block 31 can produce the power to open outside under the influence of centrifugal force, when this power is more than
During the elastic force of spring 34, holding section 311 is stretched out from opening, and is fastened togather with the interior ratchet structure 3311, prevents runner 2
It is rotated further, realizes the purpose of braking.When 2 spin down of runner or when stopping, sliding block 31 can recover under the action of spring 34
Original position, releases braking.
In the present embodiment, the wheel seat 1 is equipped with groove 11, and the tooth lid 33 includes lid body 331 and lug boss 332,
The interior ratchet structure 3311 is arranged in the lid body 331, and the shaft 4 is arranged on the lid body 331, described convex
Portion 332 is played to be inserted into the groove 11.Tooth lid 33 is detachably connected by lug boss 332 and wheel seat 1, convenient for users to according to reality
When border demand unloads or replaces tooth lid 33.
As a further improvement, the present embodiment is total, magnet 35 is equipped with the lug boss 332, the sliding block 31 is by ferromagnetic
Property material is made.In rotation process, magnet 35 can produce attraction to sliding block 31, coordinate centrifugal force, aid in the lug boss
332 stretch out opening.Meanwhile the magnet 35 is removably mounted in the lug boss 332.User can be by replacing magnetic force difference
Magnet 35 control the lower limit speed that automatic brake mechanism 3 brakes runner 2.Applicable different application scenarios.
In the present embodiment, the automatic brake mechanism 3 is two, and two automatic brake mechanisms 3 are separately positioned on institute
The both sides of runner 2 are stated, and the direction of the interior ratchet structure 3311 on the tooth lid 33 in two automatic brake mechanisms 3 is opposite.
Because an automatic brake mechanism 3 can only realize the effect of one-way brake, in order to further improve the security, the two of runner 2
Side is equipped with automatic brake mechanism 3, and braking direction is on the contrary, realize bi-directional braking.
In the present embodiment, between the wheel cap 32 is provided with two both ends being open and is equipped between the interior ratchet structure 3311
Gap.Avoid runner 2 from making sliding block 31 stretch out the situation that opening causes to brake by mistake because of shake on uneven road to occur.
In the present embodiment, the interior ratchet structure 3311 includes four ratchets, and four ratchets are uniformly distributed.Such as
This arrangement ratchet braking efficiency can be made to reach highest, will not it is overstocked because of ratchet or excessively dredge and influence braking effect.
As a further improvement, in the present embodiment, the stop part 3311-A of the ratchet is to the interior ratchet structure 3311
The center of circle direction extension.The tangent line of circumferential position where stop part 3311-A is vertical, it can preferably be fastened on holding section 311
Together, engaging effect is more preferable, greatly reduces stop part 3311-A and occurs with the situation that holding section 311 is undesirably fallen off.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
The spirit of utility model and any modification, equivalent substitution, improvement and etc. within principle, done, should be included in the utility model
Within the scope of protection.
