Specific embodiment

To make the purpose, technical scheme and advantage of the utility model embodiment clearer, below in conjunction with this practicality The technical solution in the utility model embodiment is clearly and completely described in attached drawing in new embodiment, shows So, described embodiment is the embodiment of a part of embodiment of the utility model rather than whole.Based on this practicality Embodiment in new, those of ordinary skill in the art are obtained every other without creative efforts Embodiment shall fall within the protection scope of the present invention.Therefore, the implementation to the utility model provided in the accompanying drawings below The detailed description of mode is not intended to limit claimed the scope of the utility model, but is merely representative of the utility model Selected embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative labor The every other embodiment obtained under the premise of dynamic, shall fall within the protection scope of the present invention.

In the description of the utility model, it is to be understood that the orientation or position relationship of the instructions such as term " on ", " under " To be based on orientation shown in the drawings or position relationship, being for only for ease of description the utility model and simplifying description, without referring to Show or imply that the equipment of meaning or element there must be specific orientation, with specific azimuth configuration and operation, therefore cannot manage It solves as the limitation to the utility model.

In addition, term " first ", " second " are only used for description purpose, and it is not intended that instruction or hint relative importance Or the implicit quantity for indicating indicated technical characteristic.Define " first " as a result, the feature of " second " can be expressed or Implicitly include one or more this feature.In the description of the utility model, " multiple " are meant that two or two More than, unless otherwise specifically defined.

In the utility model, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " Gu It is fixed " etc. terms should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integral；Can be Mechanical connection or electrical connection；It can be directly connected, can also be indirectly connected by intermediary, can be two The interaction relationship of connection or two elements inside element.It for the ordinary skill in the art, can basis Concrete condition understands concrete meaning of the above-mentioned term in the utility model.

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：

Please refer to Fig.1-Fig. 4, in embodiment, one kind can self-stopping wheel, including wheel seat 1, runner 2 and self-actuating brake Mechanism 3, the runner 2 are mounted on by shaft 4 on the wheel seat 1；The automatic brake mechanism 3 is used for when vehicle wheel rotational speed is too fast When, wheel is braked automatically.

In the present embodiment, the automatic brake mechanism 3 includes sliding block 31, wheel cap 32 and tooth lid 33, and the wheel cap 32 is fixed It is arranged on the side of the runner 2 and is coaxially disposed with the runner 2, the sliding block 31 is placed in the wheel cap 32, described Sliding block 31 includes sliding part 311 and two holding sections 312, and two holding sections 312 are arranged on the two of the sliding part 311 End, is arranged with elastic component on two holding sections 312, and in the present embodiment, the elastic component is spring 34.The sliding part Waist type groove is provided on 311, the waist type groove is set in the shaft 4, is provided with and is used on the 32 corresponding position of wheel cap Make two openings that two holding sections 312 are stretched out, the tooth lid 33 is fixedly connected with the wheel seat 1, and the tooth lid 33 It can be rotated compared to the runner 2, the tooth lid 33 is equipped with interior ratchet structure 3311, when described open is stretched out in the holding section 312 During mouth, the holding section 312 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 can generate the bonding force to open outside under gravitational and centrifugal forces, work as conjunction When external force is more than the elastic force of spring, holding section is open from two, and one of them is stretched out, and is engaged with the interior ratchet structure 3311 Together, runner 2 is prevented to be rotated further, realizes the purpose of braking.When runner spin down or when stopping, sliding block can be in spring It sets back and puts under effect, release 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.

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 opened there are two being equipped between the both ends of opening and the interior ratchet structure 3311 Gap.Avoiding runner 2 that sliding block 31 is made to stretch out opening because of shake on uneven road causes that brakes by mistake to happen.

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 blocking portion 3311-A of the ratchet is to the interior ratchet structure 3311 The center of circle direction extension.The tangent line of circumferential position, can preferably be fastened on holding section 312 where blocking portion 3311-A is vertical Together, it is more preferable to engage effect, greatly reduces blocking portion 3311-A and is happened with what holding section 312 was 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.
