Description
Technical field
The utility model relates to a kind of English teaching device, is specifically related to a kind of servicing unit that may be used for hanging picture.
Background technology
In teaching process, interesting and interactive in order to increase, often need to hang picture, picture poster etc.Picture be fixed with two kinds of modes, be 1. directly suspended on blackboard, more smooth after hanging up, but bad fixing, and picture cannot be hung high; 2. adopt special suspension arrangement, this kind of suspension arrangement is generally made up of bearing, support bar and fixture, for the ease of hanging, adjusting height, generally need to arrange lowering or hoisting gear, such as screw rod, leading screw and so on, listened crank to control the height of lowering or hoisting gear, although can regulate easily, but complicated integral structure, device is heavier, moves and transports cumbersome.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, proposes the English teaching servicing unit that a kind of quality gently, is easily transported, is convenient to hang picture.
The utility model realizes in the following manner: a kind of English teaching servicing unit, comprise base, base is connected with support bar, support bar is connected with cross bar, cross bar and connecting rod are hinged and connected, be provided with the first magnet in the cell body of cross bar, the first magnet and the second magnet attract each other, and the connecting rod other end is also hinged and connected with overturning-preventing bar.
Be provided with screw shell in the hinged place of cross bar and connecting rod, cross bar one end is provided with corresponding screw thread.
Described first magnet and the second magnet are ferrite permanent magnets.
Described base is provided with universal wheel.
Described support bar is connected with at least two cross bars, the cross bar distribution support bar left and right sides.
In the utility model, base, support bar etc. all adopt hollow, and quality comparation is light, convenient transportation, when suspension picture, connecting rod is in vertical state in addition, and adopt the first magnet and the second magnet can fix picture very easily, overturning-preventing bar can also be toppled over by anti-locking apparatus.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is expansion schematic diagram of the present utility model.
Fig. 3 is using state schematic diagram of the present utility model.
Wherein: 1. base, 2. support bar, 3. cross bar, 4. the second magnet, 5. picture, 6. overturning-preventing bar, 7. screw shell, 8. connecting rod, 9. the first magnet.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 to 3, English teaching servicing unit of the present utility model comprises base 1, base 1 is connected with support bar 2, support bar 2 is connected with cross bar 3, cross bar 3 and connecting rod 8 are hinged and connected, be provided with the first magnet 9, first magnet 9 in the cell body of cross bar 3 and the second magnet 4 attracts each other, connecting rod 8 other end is also hinged and connected with overturning-preventing bar 6.Described first magnet 9 and the second magnet 4 are ferrite permanent magnets.
When the utility model does not use as shown in Figure 1, now overturning-preventing bar 6 overlap with connecting rod 8, parallel with support bar 2, the occupation of land space of this timer is less, mobile more convenient.When needing to hang picture 5, the second magnet 4 is taken off, picture upper end is placed on connecting rod 8, put the second magnet 4 afterwards, the first magnet 9 and the second magnet 4 are attracted each other, picture is hung up.Because connecting rod 8 is still in vertical state, now operator stands in the arrangement that ground is easy to realize picture.Utilize overturning-preventing bar 6 to be supported by connecting rod 8 afterwards, overturning-preventing bar 6 lower end can be placed on the places such as dais.Can prevent from like this hanging this device after picture because one-sided stressed and topple over.
As preferably, be provided with screw shell 7 in the hinged place of cross bar 3 and connecting rod 8, cross bar 3 one end is provided with corresponding screw thread.When connecting rod 8 cross-brace is got up by needs time, rotate screw shell 7 to make it to be moved to the left, now one end of connecting rod 8 and cross bar 3 is all placed in screw shell 7, connecting rod 8 and cross bar 3 are in a straight line, after finishing using, reversely rotating screw shell 7 can regain connecting rod.
Described base 1 is provided with universal wheel, so that mobile device.Described support bar 2 is connected with two cross bars 3, and cross bar 3 is distributed in the support bar left and right sides, can hang two pictures so simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
