Detailed Description
The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in fig. 1 and 2, the present embodiment provides a teaching support, which includes a base 100, a supporting rod 200 and a supporting plate 300, wherein one end of the supporting rod 200 is fixedly connected to the base 100, and the other end of the supporting rod 200 is hinged to the supporting plate 300.
Specifically, in the present embodiment, as shown in fig. 8, the support bar 200 includes a first connecting bar 210, and a second connecting bar 220 and an adjusting bar 230 that are coaxially installed with the first connecting bar 210, respectively. Wherein, one end of the first connecting rod 210 is fixedly connected to the base 100, one end of the second connecting rod 220 is sleeved outside one end of the first connecting rod 210, and the second connecting rod 220 can slide on the first connecting rod 210, the other end of the second connecting rod 220 is hinged to the supporting plate 300 through the connector 240, the adjusting rod 230 is sleeved outside the first connecting rod 210, and after the adjusting rod 230 is installed on the first connecting rod 210, one end of the adjusting rod 230 abuts against one end of the second connecting rod 220, specifically, in this embodiment, an adjusting flange (not shown in the figure) is disposed at one end of the adjusting rod 230, a connecting rod flange (not shown in the figure) is disposed at one end of the second connecting rod 220, and the adjusting flange abuts against the connecting rod flange, so that the adjusting rod 230 can hold up the second connecting rod 220. In addition, in the present embodiment, as shown in fig. 6, a catch 231 is welded inside the adjustment lever 230.
In this embodiment, as shown in fig. 3 to 5, two sets of tracks are disposed on the first connecting rod 210, and the two sets of tracks are disposed oppositely, wherein each set of tracks includes a sliding slot 211 and a slot 212, the locking rod 231 can slide in the sliding slot 211, and the locking rod 231 can be locked in the slot 212. Like this, when the height of adjusting pole 230 needs to be adjusted, only need to adjust pole 230 for first connecting rod 210 is rotatory, make the both ends of kelly 231 rotate out of draw-in groove 212, and make the both ends of kelly 231 rotate in the spout 211, then will adjust pole 230 upwards or downstream can, adjust to corresponding high back, rotate once more and adjust pole 230, make the both ends rotation of kelly 231 get into in draw-in groove 212, make draw-in groove 212 support kelly 231, can make adjusting pole 230 adjust and finish. Since the second connecting rod 220 abuts against the adjusting lever 230 and the adjusting lever 230 holds the second connecting rod 220, the second connecting rod 220 is also changed according to the change of the height of the adjusting lever 230.
In the present embodiment, as shown in fig. 2 and 7, the second connecting rod 220 is hinged to the supporting plate 300 by the connecting head 240, so that the user can adjust the angle of the supporting plate 300 according to his viewing habits. Specifically, in this embodiment, the connection head 240 includes an insertion rod 242 and a chuck 241, the insertion rod 242 is fixedly connected to the chuck 241, the insertion rod 242 is inserted into the second connection rod 220, so as to facilitate the installation and removal of the connection head 240, and the chuck 241 is hinged to the support plate 300. Specifically, a chuck ear (not shown in the figure) is mounted on the chuck 241, a support plate ear is mounted at the bottom of the support plate 300, the adjusting screw 400 is screwed with the nut after penetrating through the chuck ear and the support plate ear respectively, and the angle adjusting function of the support plate 300 is realized by screwing the adjusting screw 400.
In addition, in the embodiment, the second connecting rod 220 and the adjusting rod 230 shield both the sliding groove 211 and the locking groove 212 of the first connecting rod 210, so that people cannot observe the sliding groove 211 and the locking groove 212 from the outside, and the appearance of the whole supporting rod 200 is improved.
