Abstract

The utility model relates to the category of blackboards, in particular to a movable blackboard capable of automatically wiping. The technical scheme adopted by the utility model is that: the blackboard comprises a base (12), a frame (1) and an upper frame (7), wherein a track is formed on the frame (1) and is connected with a blackboard A (2) and a blackboard B (3). The movable blackboard capable of automatically wiping is characterized in that: the track consists of a rear track (4), a middle track (5), a front track (6), and an upper track (10) and a lower track (11) which are communicated with the rear track (4), the middle track (5) and the front track (6); and wiping pieces (13) are arranged at the back faces of the blackboard A (2) and the blackboard B (3). The movable blackboard capable of automatically wiping has the advantages that: as the wiping pieces (13) are arranged on the blackboard A and the blackboard B, the blackboard A and the blackboard B are convenient to wipe as required so as to relieve the teaching load of a teacher and improve the efficiency.

Description

Automatically the Reelable blackboard of wiping

Technical field

The utility model relates to the B43L1/04 blackboard classification on the International Classification of Patents (IPC) by retrieval, especially belongs to the Reelable blackboard of wiping automatically.

Background technology

Traditional blackboard adopts the form of monolithic mostly, like this on blackboard too the place of high position write not too conveniently, and often want blackboard wiping in the use.Chinese patent by retrieval, it is 200610069386.7 that discovery has the patent No., name is called the patent of lamination blackboard, this patent disclosure a kind of blackboard of forming by two blackboard pieces, when this blackboard uses, can be with the automatic wiped clean of following one blackboard, but this blackboard can't solve the automatic wiping problem of a top blackboard, and how to keep the content on the following blackboard when needed and need not the problem of wiping.

Summary of the invention

The purpose of this utility model is to provide a kind of wiping as required and keeps the Reelable blackboard of wiping automatically of content on the blackboard, to solve Automatic erasing blackboard and the problem of content on the reservation blackboard when needing.

Technical solution adopted in the utility model is: it comprises base (12), frame (1) and upper ledge (7), on frame (1), be shaped on track, track links to each other with blackboard A (2), blackboard B (3), it is characterized in that: described track is by back track (4), middle orbit (5) and preceding track (6), and will back track (4), middle orbit (5) and preceding track (6) connection get on the right track (10) and lower railway (11) is formed; The back side of described blackboard A (2) and blackboard B (3) all is shaped on wiper blade (13); Blackboard A (2) is connected with lower railway (11) with back track (4), middle orbit (5), preceding track (6), get on the right track (10) by connector (14) with blackboard B (3).

The beneficial effects of the utility model are: 1, since in the utility model blackboard A, blackboard B all have wiper blade, can be as required blackboard wiping A, blackboard B easily, alleviated teacher's the burden of giving a lesson so greatly, improved efficient; 2, the design of back track in the utility model can be guaranteed can not wiped by wiper blade the literal that needs keep, the trouble of writing again again after needing having avoided the literal that keeps by wiping.

Wherein: 1, frame 2, blackboard A 3, blackboard B 4, back track 5, middle orbit 6, preceding track 7, upper ledge 8, lowering or hoisting gear box 81, lowering or hoisting gear 9, push-pull device at fixed box 91, push-pull device at fixed 10, get on the right track 11, lower railway 12, base 13, wiper blade 14, connector

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As Fig. 1 is that the utility model rear perspective view, Fig. 2 are blackboard A stereogram for the utility model front view, Fig. 3 for A-A view, Fig. 4 of Fig. 2, the utility model comprises base (12), frame (1) and upper ledge (7) as shown, on frame (1), be shaped on track, track links to each other with blackboard A (2), blackboard B (3), it is characterized in that: described track is by back track (4), middle orbit (5) and preceding track (6), and will back track (4), middle orbit (5) and preceding track (6) connection get on the right track (10) and lower railway (11) is formed; The back side of described blackboard A (2) and blackboard B (3) all is shaped on wiper blade (13); Blackboard A (2) is connected with lower railway (11), and can moves forward and backward up and down as required in track with back track (4), middle orbit (5), preceding track (6), get on the right track (10) by connector (14) with blackboard B (3).

Be shaped on push-pull device at fixed box (9) on the frame described in the utility model (1), in push-pull device at fixed box (9), be shaped on push-pull device at fixed (91); Be shaped on lowering or hoisting gear box (8) on the described upper ledge (7), in lowering or hoisting gear box (8), be shaped on lowering or hoisting gear (81).

Wiper blade described in the utility model (13) is to adopt sponge material to make.

The course of work of the present utility model is: when bringing into use, blackboard A (2), blackboard B (3) is positioned on the preceding track (6), after following blackboard A (2) writes literal, when needing wiping, it can be pushed middle orbit (5), top blackboard B (3) is left behind, blackboard B (3) wiper blade (13) behind just can will be positioned at blackboard A (2) wiped clean of writing literal on the middle orbit (5), the blackboard A (2) that will be positioned at middle orbit (5) then moves the top to, and shift onto on the preceding track (6), because blackboard A (2), the structure that blackboard B (3) adopts is the same, be that the back side all is shaped on wiper blade (13), therefore, just can reach with blackboard A (2) as long as repeat above step, blackboard B (3) is used alternatingly the also purpose of wiped clean.

In the use, when the content that runs into the blackboard A (2) that writes literal need keep, it can be pushed back track (4), because back track (4) the preceding track of distance (6) is far away, therefore, blackboard B (3) above being positioned at preceding track (6) can guarantee that the blackboard A (2) that is positioned on the back track (4) can not wiped by wiper blade (13) when leaving behind.

In addition, the utility model can directly be produced on track, push-pull device at fixed (91) and lowering or hoisting gear (81) etc. in the body of wall when concrete the making, takes up room with minimizing.
