Abstract

Replaceable magnetic black-white blackboard eraser, is made up of arc shell handle (1) and rub body (2) two parts.Rub body (2) is made up of corduroy wiper, pearl continuous pad, wiping board and wiper Four built in boundaries frame.The wiping board back side is provided with wiper Four built in boundaries muscle (3) and fixing threaded hole post (4), wiping board reinforcement (5) and magnet head into circle (6).Wiper Four built in boundaries frame, is provided with and shirks block tongue (7) and fixing threaded hole (8).Arc shell handle (1), in the middle of it, outer both sides are provided with and shirk convex arc (9) and shirk bayonet socket (10); Be provided with permanent magnet in it and cylindrical enclosure (11) is installed, and permanent magnet is housed.Rub body (2) is arranged in shell handle (1), namely forms replaceable magnetic black-white blackboard eraser.Rub body (2) replaceable use, solves after common black-white board wiper is damaged and namely entirely loses, and causes the problem of waste and environmental pollution.Because this black-white board wiper has permanent magnetic, fixed on black and white plate by suction with rear, solve the problem that common black-white board wiper is placed on the pollution on dais.

Description

Replaceable magnetic black-white blackboard eraser

Technical field

School supply and stationery: replaceable magnetic black-white blackboard eraser

Technical background

Conventional traditional black-white board wiper is fragile, namely entirely loses after damaging, and waste is large, and brings environmental pollution., be placed on after using on dais meanwhile, cause the pollution to dais.Given this, the replaceable magnetic black-white blackboard eraser of special research and development, makes it more perfect, uses more convenient.

Summary of the invention

Replaceable magnetic black-white blackboard eraser (Fig. 1).

This is black is equipped with permanent magnet from wiping, and can be inhaled and fix on black and white plate, solve after common black-white board wiper uses and be placed on pollution problem dais caused to dais by magnetic force.The replaceable use of this black-white board wiper rub body, solves after common black-white board wiper is damaged and namely entirely loses, and waste is large, and the problem of contaminated environment.

(1) design structure spy card:

This black-white board wiper, is made up of rub body (2) and shell handle (1) two parts.

A, rub body (2), be made up of corduroy wiper, pearl continuous pad, wiping board (Fig. 2) and wiper Four built in boundaries frame (Fig. 3, Fig. 4) four part.Wiping board (Fig. 2), its back side is provided with wiper Four built in boundaries muscle (3), fixing threaded hole post (4), wiping board reinforcement (5) and magnet and heads into circle (6).Wiper Four built in boundaries frame (Fig. 3, Fig. 4) is provided with and shirks block tongue (7) and fixing threaded hole (8).The continuous pad pad of pearl is in the front of wiping board (Fig. 2), corduroy wiper is arranged on pad, its Four built in boundaries is on the wiper Four built in boundaries muscle (3) at the wiping board back side, wiper Four built in boundaries frame (Fig. 3, Fig. 4), be arranged on the wiping board back side (Fig. 2), namely four limits of wiper are pushed down, the rub body (2) that just formation one is complete.

B, shell handle (1), be made up of shell handle (Fig. 5) and permanent magnet two parts.Shell handle (Fig. 5), in the middle of it, outer both sides are provided with and shirk convex orphan (9) and shirk bayonet socket (10); Be provided with magnet in it and cylindrical enclosure (11) is installed.Permanent magnet is just arranged in cylindrical enclosure (11).Rub body (2) is loaded in shell handle (1), makes to shirk block tongue (7) and block and shirk in bayonet socket (10), just form the removable magnetic black-white blackboard eraser of rub body (2).

(2) actual effect feature is used

Replaceable magnetic black-white blackboard eraser, special owing to designing, reach special result of use.

1, permanent magnet is arranged in shell handle (11), the back side magnet that top is contained in wiping board (Fig. 2) heads in circle (6), shorten the distance of magnet and black-white board wiper, enhance magnetic force, can be fixed on black and white plate by suction in front after making black-white board wiper wiping, avoid after black-white board wiper uses and be placed on pollution dais caused to dais, and very easy to use.

2, because rub body (2) can conveniently shirk, the easily dirty afterwards rub body (2) of use conveniently can take off cleaning, conveniently replaced use after rub body damages, namely entirely lose after black-white board wiper is no longer damaged, greatly reduce the waste of resource and the pollution of environment, reach energy-conserving and environment-protective, long-lived object.

Detailed description of the invention:

This black-white board wiper component parts all can be purchased or special voluntarily.First make rub body (2): continuous for pearl pad pad in the front of wiping board (Fig. 2), corduroy wiper is arranged on pad, its Four built in boundaries is on the wiper Four built in boundaries muscle (3) at the wiping board back side, wiper Four built in boundaries frame (Fig. 3, Fig. 4), be arranged on the wiping board back side (Fig. 2), namely four limits of wiper are pushed down, the rub body (2) that just formation one is complete.Then arc shell handle is made, again magnet is arranged in the installation cylindrical enclosure (11) of arc shell handle, finally rub body (2) is arranged in shell handle (1), make to shirk block tongue (7) to block and shirk bayonet socket (10), form a complete black-white board wiper, can use.Shirk convex arc (9) outwards exert oneself if nipped with thumb, rub body (2) just can shirk from bayonet socket (10).Like this, just reach the object of rub body (2) replaceable use, change the present situation of namely entirely losing after traditional black-white board wiper is damaged, considerably reduce waste and environmental pollution, and easy to use, durable in use.Because permanent magnet is arranged in cylindrical enclosure (11), black-white board wiper just has permanent magnetic, fixed on black and white plate by suction after black-white board wiper can be made to use, avoid after black-white board wiper uses and be placed on pollution dais caused to dais, maintain the sanitation and hygiene at dais.Replaceable magnetic black-white blackboard eraser, deserves to be called the best black-white board wiper of utility model.
