Hidden danger, just in case due to bolt falling on the ground, the sporter run rapidly steps on, and causes traumatic injury, simultaneously bolt loosen very
To coming off, go maintenance without staff so that the service life of basketball stands is greatly shortened, so design one can be delayed
Rush vibratory impulse, and the attachment means as far as possible not allowing the energy of vibration be delivered between the backboard of basketball stands and basketball stands is current
The problem needing to solve.
Summary of the invention
This utility model provides a kind of backboard basketball stand vibration damping connection device, it is therefore an objective to stop owing to basketball is pounded at basket as far as possible
The vibration produced on plate is delivered on basketball stands, prevents connecting bolt or basket ball board from loosening and even comes off, thus ensures motion
The safety of personnel.
To achieve these goals, the technical scheme that this utility model is taked is: a kind of backboard basketball stand vibration damping connects dress
Putting, including link body, spring, vibration-absorbing rubber sleeve and connection ball cover, described link body is provided with bolt connecting hole one,
During wherein vibration isolation rubber is sheathed on bolt connecting hole one, spring one end is connected with link body, the other end be connected ball cover
Bottom welding is fixing to be connected.
Preferably, this internal being provided with bottom cylindrical cavity, and cylindrical cavity of described link is provided with annular slot.
Preferably, described connection ball cover is crossed the centre of sphere and is provided with bolt connecting hole two, and is provided with rubber at the top connecting ball cover
Pad.
Preferably, described rubber blanket is spherical shape, and just be connected ball cover composition whole spherical.
This utility model be to try to stop due to basketball pound on backboard produce vibration be delivered on basketball stands, the company of preventing
Connecting bolt or basket ball board loosen and even come off, thus ensure the safety of players, for solving the problems referred to above, to backboard and
Attachment means between basketball stands has done brand-new design, uses above technical scheme to provide the benefit that: at link body
On the inwall of bolt connecting hole one be provided with vibration-absorbing rubber sleeve, additionally in the cylindrical cavity of link body, be provided with spring,
And one end of spring is connected with the annular slot bottom cylindrical cavity, the other end and the bottom welding being connected ball cover, and connecting
It is additionally provided with rubber blanket on ball cover, is well buffered the vibration coming from backboard by vibration-absorbing rubber sleeve, spring and rubber blanket, will
The energy dissipation of vibration, in backboard and the junction of basketball stands, effectively prevent vibration and passes to basketball stands, it is ensured that basketball
The stability of the structure on frame, also ensure that the safety of players.

Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is made the most in detail
Thin explanation, it is therefore an objective to help those skilled in the art design of the present utility model, technical scheme are had more complete, accurately and
Deep understanding, and contribute to its enforcement.
As shown in Figure 1 and Figure 2, this utility model is a kind of backboard basketball stand vibration damping connection device, be used to stop as far as possible by
Pound, in basketball, the vibration produced on backboard to be delivered on basketball stands, prevent connecting bolt or basket ball board from loosening and even come off,
Thus ensure the safety of players.
Specifically, as shown in Figure 1 and Figure 2, including link body 1, spring 7, vibration-absorbing rubber sleeve 3 and connection ball cover 4,
Described link body 1 is provided with bolt connecting hole 1, during wherein vibration-absorbing rubber sleeve 3 is located at bolt connecting hole 1, and spring 7 one
End is connected with link body 1, and the other end is fixing with the bottom welding being connected ball cover 4 to be connected；As in figure 2 it is shown, described link
It is provided with bottom cylindrical cavity, and cylindrical cavity in body 1 and is provided with annular slot 8；Described connection ball cover 4 is crossed the centre of sphere and is provided with bolt even
Connect hole 25, and be provided with rubber blanket 6 at the top connecting ball cover 4；Described rubber blanket 6 is spherical shape, and just be connected ball cover
4 compositions are whole spherical.
With specific embodiment, specific works mode is illustrated below:
During installation, bolt initially passes through the bolt connecting hole 1 of link body 1 side, then draws connection ball cover 4 to make bullet
Spring 7 stretches until connecting the axis of the bolt connecting hole 22 of ball cover 4 and the axis of the bolt connecting hole 1 on link body 1
Conllinear, after then bolt being passed the bolt connecting hole 25 connected on ball cover 4, at the spiral shell through link body 1 other side
Bolt connecting hole 1, now spring 7 is in extended state, and install connect later the rubber blanket 6 on ball cover 4 just with
Backboard contacts.
When backboard is by the percussion of basketball, and when transferring vibrations to vibration damping connection device, now bolt can be at bolt
Connecting hole 1 vibrates, and can vibrate with link body 1, now vibration-absorbing rubber sleeve 3 meeting in bolt connecting hole 1
Absorbing a part of vibrational energy, make an energy attenuation part for vibration, then the vibration of bolt can be by connecting ball cover 4 to spring
7 produce active force, and the spring 7 being now stretched can absorb a part of vibrational energy, and while spring 7 acts on, connect ball
Rubber blanket 6 on set 4 also alleviates the energy of vibration, so to greatest extent by the energy dissipation of vibration at vibration damping connection device
Place, effectively prevent vibration and passes to basketball stands, it is ensured that the stability of the structure on basketball stands, also ensure that players
Safety.
Above in association with accompanying drawing, this utility model is exemplarily described, it is clear that this utility model implements not
Limited by aforesaid way, as long as have employed the various unsubstantialities that method of the present utility model design is carried out with technical scheme
Improvement；Or the most improved, above-mentioned design of the present utility model and technical scheme are directly applied to other occasion, all at this
Within the protection domain of utility model.
