Technical Field

The utility model relates to a teaching equipment field specifically is a junior middle school english word wall.

Background

At present, in the process of English learning in schools, except for normal classroom learning, students can also utilize fragmented time to learn English, an English word wall is a good mode, and students can learn anytime and anywhere by watching the content on the word wall at any idle time. In most mathematics schools, a word wall is formed by selecting a blank wall and pasting words as the word wall, or selecting a blackboard on the wall to write words or paste words as the word wall, and students usually fill in and paste contents. However, for the middle school students, the students are in the growth and development period, the height of each student is different and may have a large difference, the word wall with a relatively fixed height cannot adapt to the height of each student at present, the students are good for the high school students, but the students with the low school need to move the stool to ascend, and certain potential safety hazards exist. Although there is the blackboard that can slide from top to bottom at present can regard as a word wall, but there is certain requirement to the vertical height in classroom, and the installation just is not convenient for not enough, simultaneously because lack certain vertical stop device, under the exogenic action, the condition of whereabouts probably appears, causes the injury to the classmate of blackboard below. In addition, various glues are needed in the process of pasting the blackboard or the wall, and the glues are not easy to clean, so that the wall or the board becomes dirty and disordered in the long term. For the big problem of adaptation junior middle school student's height span, the student of being convenient for carries out the spelling of word and pastes on the word wall, the utility model provides a junior middle school english word wall.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a junior middle school's english word wall to adapt to the height difference nature of every position classmate, the student of being convenient for carries out the word spelling on the word wall and pastes.

In order to solve the technical problem, the utility model discloses a technical scheme is:

a junior middle school's english word wall includes base, lead screw, belt, magnetism blank, shell. The pedestal mounting is on the wall, both sides subtend is equipped with U type guide rail, two in the base be equipped with between the guide rail the magnetism blank, magnetism blank both sides are equipped with the gyro wheel, the gyro wheel is in the guide rail, the magnetism blank can be followed the guide rail slides, be connected with the thread bush on the magnetism blank, the base both sides are equipped with the lead screw, thread bush threaded connection is in on the lead screw, be equipped with the belt pulley on the lead screw, two pass through between the belt pulley the transmission is connected to the belt, still be equipped with the hand wheel on the lead screw, the shell is detained on the base, the shell openly has square through hole.

Further, the magnetism blank is soft magnetic whiteboard, there are horizontal strengthening rib and vertical strengthening rib at the magnetism blank back, horizontal strengthening rib can not take place big deformation, vertical strengthening rib can take place big deformation and toughness strong.

Further, the belt adopts a synchronous belt.

Further, the lead angle of the lead screw is less than 30 degrees.

Furthermore, the square through hole on the front surface of the shell is divided into an upper part and a lower part.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", "back", "vertical", "lateral", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-7, the utility model discloses a junior middle school english word wall, including base 1, lead screw 2, belt 3, magnetism blank 4, shell 5. The base 1 is a cuboid shell, no wall surface exists in the front of the base 1 and the bottom surface of the base 1, the base 1 is installed on the wall surface, U-shaped guide rails 101 are oppositely arranged on two sides in the base 1, the guide rails 101 are from the uppermost side to the lowermost side in the interior, the section of each guide rail 101 is T-shaped, a magnetic white board 4 is arranged between the two guide rails 101, a plurality of rollers 401 are arranged on two sides of each magnetic white board 4, the rollers 401 can roll in the U-shaped guide rails 101, so that the magnetic white board 4 can slide and turn along the U-shaped guide rails 101, the upper part of the oblique rear part of the magnetic white board 4 is connected with a threaded sleeve 402, the inner surface of the threaded sleeve is provided with threads, screw rods 2 are respectively arranged in the vertical direction on two sides of the base 1, the screw rods 2 rotate, guide through holes 102 are arranged on two sides of the base 1, the threaded sleeve 402 penetrates through the guide, the upper end of lead screw 2 is equipped with belt pulley 201, connects the transmission through belt 3 between belt pulley 201 on two lead screws 2, and the lower extreme of lead screw 2 is equipped with hand wheel 202, and shell 5 is a cube casing and detains on base 1 and carry out the protection, and shell 5 openly has square through-hole 501 can see the surface of magnetism blank 4.

Further, magnetic whiteboard 4 is soft magnetic whiteboard, has horizontal strengthening rib 403 and vertical strengthening rib 404 at magnetic whiteboard 4 back, and horizontal strengthening rib 403 can not take place big deformation, and vertical strengthening rib 404 can take place big deformation and toughness strong to make magnetic whiteboard 4 can be comparatively smooth move along guide rail 101. The belt 3 adopts a synchronous belt, so that the same rotation angle of each screw rod 2 is ensured. The lead angle of the screw rod 2 is less than 30 degrees, so that the magnetic white board 4 is prevented from sliding downwards under the action of gravity. The square through hole 501 in the front of the housing 5 is divided into an upper part and a lower part, so that the working area of the magnetic whiteboard 4 can be conveniently divided. The maximum height of the U-shaped guide rails 101 is larger than the height of the square through hole 501 in the front of the shell 5, and the minimum distance between the two U-shaped guide rails 101 is larger than the width of the square through hole 501 in the front of the shell 5, so that the attractiveness is enhanced.

The working principle is as follows: before using, only need with the utility model discloses install on the wall can. In the use, hand wheel 202 through rotating arbitrary side, can make lead screw 2 rotate, and make opposite side lead screw 2 carry out synchronous rotation through belt pulley 201 and belt 3, thereby lead screw 2 rotates and makes the cover realize upwards or move down and drive and the magnetism blank 4 of being connected with thread bush 402 on lead screw 2, after magnetism blank 4 moves suitable position, can carry out the spelling of word on magnetism blank 4 or attract on magnetism blank 4 through little magnet with relevant word card or word poster, then reset can rotating hand wheel 202.

Further, the above-mentioned fixed connection and fixed mounting are to be understood in a broad sense unless otherwise specifically stated or limited, and may be, for example, welding, gluing, or integrally formed, as is conventional in the art.

The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
