Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Example one

As shown in fig. 1-4, the present embodiment provides a support for recording lessons, which includes a base 1, a support rod 2 is disposed on the base 1, the support rod 2 is preferably an expansion rod, a support plate 3 is connected to the top end of the support rod 2, and the support plate 3 is used for placing a camera 17 to play a supporting role; the bottom of base 1 is equipped with wheel 13, the convenient removal.

The base 1 is provided with a sliding cavity 12, sliding rods 4 are arranged in the sliding cavity 12 in a sliding mode, and a pair of sliding rods 4 are symmetrically arranged; outside 4 one ends of slide bar stretched out base 1, the equipartition was provided with a plurality of bosss 8 on the

slide bar

4, and 8 top surfaces of bosss slope sets up, and 4 one end threaded connection of slide bar have screw rod 6, and the bottom of screw rod 6 is connected with sucking disc 5, and the top of screw rod 6 is equipped with twist grip 7, the convenient rotation.

Still be equipped with stop gear on the base 1, stop gear includes the connecting plate 18 that links to each other with base 1, connecting plate 18 is "L" type setting, jack 19 has been seted up on the connecting plate 18, it is equipped with ka tai 9 to insert in the jack 19, the bottom surface of ka tai 9 also inclines to set up and is unanimous with the top surface incline direction of boss 8, ka tai 9 top is equipped with keeps off the platform 11, connecting plate 18 is connected with spring 10, spring 10 cover is established on ka tai 9, the other end of spring 10 links to each other with keeping off platform 11.

Because sucking disc 5 adsorbs subaerial, the student plays very easily and meets sucking disc 5 or slide bar 4, through setting up ka tai 9, can prevent to break away from the problem that leads to unable absorption, stability to reduce because of the mistake bumps 5 and breaks away from the sucking disc 5 that leads to the fact with slide bar 4 kicking into base 1 sliding chamber and ground.

The specific working process is as follows:

when using, with the support through wheel 13 remove the assigned position, take slide bar 4 out, boss 8 can jacking ka tai 9 at the removal in-process, ka tai 9 rises, spring 10 receives the pulling force, when boss 8 does not contact with ka tai 9, ka tai 9 falls into and realizes spacing to slide bar 4 in the space between the double-phase adjacent boss 8, according to above-mentioned principle, according to actual space size, take one section distance out with the slide bar, then downwardly rotating screw rod 6, screw rod 6 drives sucking disc 5 and moves down until adsorbing subaerial, accomplish the fixed of support.

It can be seen that the arm of force between the sucker 5 and the support rod 2 is increased by sliding the sliding rod 4, so that a larger stable supporting force can be provided, the support can be prevented from tilting even if a student accidentally touches the support, and the stability is good; meanwhile, when the bracket is not used, the clamping table 9 is pulled upwards, and the sliding rod 4 is pushed back to the sliding cavity 12 of the base 1, so that the clamping table is convenient to store, and the occupied space is reduced.
