Children are engaged in basketball movement, are conducive to child stage to the universal of basketball movement and promote.
The technical solution of the above-mentioned prior art has the following defects, since upper basketball stands are inserted into lower basketball stands, in rain
It when, rainwater is flowed into the gap easily between upper basketball stands and lower basketball stands on lower basketball stands, is caused inside lower basketball stands
Corrosion, the service life of basketball stands is short.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of for going up and down the liter of basketball stands
Falling unit is met water and is not easily accessible in fixed cylinder, extends the service life of lifting device.
To achieve the above object, the utility model provides following technical solution:
It is a kind of for going up and down the lifting device of basketball stands, including fixed cylinder, wear and slide axially along fixed cylinder is parallel to
Mobile bar, the driving mechanism for driving mobile bar to move for being connected to fixed cylinder, mobile bar are stretched out fixed cylinder one end and are equipped with
It is sheathed on mobile bar and the basketball stands for being fixed on basketball stands, the locking for locking mobile bar and basketball stands relative position
Part, basketball stands are sheathed on fixed cylinder and move axially with mobile bar along fixed cylinder.
By using above-mentioned technical proposal, when longitudinal height of Yao Shenggao basketball stands, driving mechanism drives mobile bar along solid
Safety barrel is axially moved (moving upwards along the vertical direction), the fixed basketball stands in fixed cylinder one end is stretched out with mobile bar, with movement
Bar moves up.Since basketball stands are sheathed on fixed cylinder, so, during mobile bar moves up, mobile bar leaves fixation
The end face (i.e. the top face of fixed cylinder) of cylinder is coated in basketball stands.In the rainy day, rainwater will not be from fixed cylinder and movement
Gap between bar, penetrates into fixed cylinder.
The utility model is further arranged to: locking piece is the lock that basketball stands and mobile bar are radially arranged in along basketball stands
Rationed marketing.
By using above-mentioned technical proposal, locking pin is radially arranged in basketball stands and mobile bar along basketball stands, in this way, limitation
