CN202685668U - Sliding blackboard - Google Patents

Abstract

The utility model relates to a sliding blackboard which comprises a base plate and a panel. The panel comprises upper and lower plates. Single-hand pull rings are respectively arranged in the middle of the lower edges of the upper and lower plates. According to the technical scheme, the sliding blackboard provided by the utility model can ensure the balance of the upper and lower plates during a pushing and pulling process; a pulley which cannot slide because of the inclining of the upper and lower plates is avoided; and the use is more convenient.

Description

Blackboard slidably

Technical field

The utility model relates to a kind of reusable plate of writing or drawing or tablet, relates to specifically a kind of blackboard.

Background technology

At present, blackboard for teaching all is to be fixed on the place ahead, classroom, serves as a teacher the writing on the blackboard content when more, and partial content is positioned at the blackboard below, causes the student who arranges behind the classroom to see clearly, and the teacher is at the top of blackboard and not too convenient during the writing on the blackboard of bottom.For overcoming the problems referred to above, a kind of slidably blackboard now commonly used, this slidably blackboard comprises base plate and panel, the base plate both sides are respectively equipped with chute, panel is divided into upper plate body and lower body two parts, on, the lower body two ends are respectively equipped with pulley, and on, the pulley at lower body two ends is arranged in the chute of base plate both sides respectively, draw or push to, during lower body, on, lower body all relatively chute slide up or down, but in pulling or promote, during lower body, on, lower body often produces inclination because of unbalance stress, can't slide thereby pulley is stuck in the chute, impact is used.

The utility model content

The purpose of this utility model provides a kind of slidably blackboard, and its plate body that can guarantee blackboard keeps balance in sliding process, use more convenient.

To achieve these goals, technical solution of the present utility model is: a kind of slidably blackboard, comprise base plate and panel, and panel comprises upper and lower plate body, the middle part of described upper and lower plate body lower limb is respectively equipped with a singlehanded draw ring.

The utility model is blackboard slidably, wherein, described upper and lower plate body lower limb also is respectively equipped with upper and lower both hands draw ring, upper and lower both hands draw ring includes two handles, two handles of described upper both hands draw ring are symmetrical along the center line of upper plate body length direction, and two handles of described lower both hands draw ring are symmetrical along the center line of lower body length direction.

After adopting such scheme, the utility model slidably blackboard is respectively equipped with singlehanded draw ring at upper and lower plate body lower limb, therefore push away or pull at needs, during lower body, can come push-and-pull by singlehanded draw ring, because singlehanded draw ring is located at the middle part of upper and lower plate body lower limb, therefore guarantee that upper and lower plate body keeps balance in drawing process, prevents that upper and lower plate body from can't slide because inclination makes pulley, uses convenient.

Description of drawings

Fig. 1 is the slidably structural representation of blackboard of the utility model.

Specify slidably blackboard of the utility model below in conjunction with accompanying drawing.

The specific embodiment

As shown in Figure 1, the utility model slidably blackboard comprises base plate 1 and panel 2, base plate 1 both sides are respectively equipped with a left side, right rail 11,12, panel 2 comprises upper plate body 21, lower body 22, upper plate body 21, the two ends, the left and right sides of lower body 22 are provided with pulley respectively, upper plate body 21, the pulley at lower body 22 two ends is arranged at a left side respectively, right rail 11, in 12, on, lower body 21, the middle part of 22 lower limbs is respectively equipped with singlehanded draw ring 3,4, more convenient for using, on, lower body 21,22 lower limbs also are respectively equipped with, lower both hands draw ring 5,6, two handles of upper both hands draw ring 5 are symmetrical along the center line of upper plate body 21 length directions, and two handles of lower both hands draw ring 6 are symmetrical along the center line of lower body 22 length directions.

The above embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.

Claims (2)

1. a blackboard slidably comprises base plate (1) and panel (2), and panel (2) comprises upper and lower plate body (21,22), it is characterized in that: the middle part of described upper and lower plate body (21,22) lower limb is respectively equipped with a singlehanded draw ring (3,4).

2. slidably blackboard as claimed in claim 1, it is characterized in that: described upper and lower plate body (21,22) lower limb also is respectively equipped with upper and lower both hands draw ring (5,6), upper and lower both hands draw ring (5,6) includes two handles, two handles of described upper both hands draw ring (5) are symmetrical along the center line of upper plate body (21) length direction, and two handles of described lower both hands draw ring (6) are symmetrical along the center line of lower body (22) length direction.
