Detailed description of the invention
By describing technology contents of the present utility model in detail, realized object and effect, accompanying drawing is coordinated to be explained below in conjunction with embodiment.
The design of the utility model most critical is: on electronic unsettled folding basketball support, set up speed difference automatic controller, utilize the speed difference latch functions of speed difference automatic controller to prevent basketball stands from surprisingly to drop the impact failure caused, improve stability and the security of electronic unsettled folding basketball support.
Concrete, please refer to shown in Fig. 1, the electronic unsettled folding basketball support of the utility model embodiment, comprise upper frame 1, swing arm 2, engine 3, support rod mechanism 4 and backboard 5, electronic unsettled folding basketball support is fixed on roof by upper frame 1, backboard 5 is articulated with on upper frame 1 by swing arm 2, the side of swing arm 2 is provided with engine 3, the opposite side of swing arm 2 is provided with support rod mechanism 4, engine 3 drives swing arm 2 swing up and down around pin joint and to naturally droop or level is packed up, also comprise speed difference automatic controller 6, one end of described speed difference automatic controller 6 is fixed on upper frame 1, the other end of described speed difference automatic controller 6 is fixed in swing arm 2.
From foregoing description; the beneficial effects of the utility model are: by setting up speed difference automatic controller; the speed difference latch functions that speed difference automatic controller has can absorb electronic unsettled folding basketball support because of nylon shioze ribbon or steel wire rope moment of failure and to drop the speed produced; basketball stands are avoided surprisingly to drop the impact failure caused; thus protect the stability of whole electronic unsettled folding basketball support, improve the security of electronic unsettled folding basketball support.
Further, described speed difference automatic controller 6 comprises shell, drum, safety rope 61 and clockwork spring assembly, described shell is fixed on upper frame 1 by anchor ear 7, described drum is arranged in the enclosure, drum is formed with a cannelure, safety rope 61 is arranged in described cannelure, a left side for drum, right side is respectively provided with a mounting groove, clockwork spring assembly adaptation is arranged in right mounting groove, one end of safety rope 61 is connected with one end of clockwork spring assembly, the other end of safety rope 61 stretches out outside shell and is fixedly connected with swing arm 2, a locking system is provided with in the left mounting groove of drum, locking system comprises the ratchet that frictionally fixes position, at least one extension spring and at least one ratchet, the bottom surface of the left mounting groove of drum is provided with a boss, one end of ratchet is set in boss forms with boss and is flexibly connected, ratchet is provided with spring retainer ring, extension spring to be arranged on ratchet and to form inside pulling force to ratchet, ratchet sleeve is located at the outer end of boss, the inwall of ratchet forms at least one tooth that can mutually be engaged with ratchet outer end.
The operation principle adopting above-mentioned speed to differ from automatic controller is:
Drum and clockwork spring is had in the shell of speed difference automatic controller, safety rope 61 one end connects with drum, and around on drum groove, the other end stretches out outside shell and is fixedly connected with swing arm 2, when basketball stands normally put down use (engine 3 drives swing arm 2 to naturally droop to lower swing around pin joint), leaving behind at the uniform velocity slowly in one end that safety rope 61 is connected with swing arm 2, drive drum to rotate, safety rope 61 pulls out; When basketball stands normally pack up do not use time (engine 3 drives swing arm 2 upwards to swing and level is packed up around pin joint), one end that safety rope 61 is connected with swing arm 2 is turned round at clockwork spring effect boot pulley, and safety rope 61 is automatically on wraparound drum; When basketball stands surprisingly drop, one end that safety rope 61 is connected with swing arm 2 is accelerated instantaneously, drives drum fast rotational, under the influence of centrifugal force, ratchet on drum is thrown out of, collide with the tooth on ratchet, when impulsive force reaches setting value, ratchet is fixed or ratchet starts to rotate, again owing to being provided with friction plate, ratchet is subject to frictional force effect forces drum to slow down until stop the rotation at leisure, and safety rope 61 can not pull, and plays latch functions; Removing when acting on the load on safety rope 61, under extension spring effect, by two ratchet adduction, departing from the tooth on ratchet, recover again normal work.
From foregoing description, the beneficial effects of the utility model are: adopt the above-mentioned locking system be made up of ratchet, extension spring and ratchet, can basketball stands be fast and effeciently stoped surprisingly to drop, significantly reduce the destruction that impulsive force causes, the stability of the electronic unsettled folding basketball support of further raising and security, and compact conformation, dependable performance.
