Description
The utility model relates to the novel elevating blackboard.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; The assistant product group of writing or draw, big group of reusable plate of writing or drawing or tablet, the little technical group field of blackboard.Classification number is B43L1/04.
At present, the technology about blackboard existing and that once had was all done very fruitful effort to the demand of novel elevating blackboard, also once designed many outstanding technical schemes.As the Decree of Patent Office of China in 1996 by declaring in the Wang Tian township, Granted publication number is CN2243392Y, China Patent No. (ZL) is: No. 95234175.1 utility model title is the utility model patent of " multi-functional blackboard ", the technical scheme that is adopted.Be a routine of great value invention aspect blackboard, it has solved the problem of blackboard effectively.But still have some deficits, the teacher of the different heights of its also very difficult solution uses the problem of blackboard inconvenience.
The purpose of this utility model is to provide the novel elevating blackboard.Use the problem of blackboard inconvenience with the teacher who solves different heights.
The purpose of this utility model is achieved in that the novel elevating blackboard of this utility model.Mainly constitute by blackboard, tooth bar, fixator, gear, chalk platform, fixed mount, pulley rail.Its blackboard, tooth bar, gear are by selecting for use on the market.Its fixator is the rocking arm shape, uses the steel material, through forging processing and manufacturing.Its chalk platform is an elongate in shape, uses wooden material, through the planing operation manufacturing.Its fixed mount is " U " shape shape, uses the steel material, through forging processing and manufacturing.Its pulley rail is an elongate in shape, uses the steel material, through forging processing and manufacturing.Blackboard adopts screw method to be installed in the back position of tooth bar, constitutes the conjuncted structure of T-shaped shape, and function is to serve to spur.Tooth bar adopts contact method to be installed in the end position of fixator, constitutes T-shaped shape contact structures, and function has been a fixation.Tooth bar adopts contact method to be installed in the left rail position of fixed mount, constitutes the conjuncted structure of a shape, and function has been to lead action to use.Gear employing methods of engagement is installed in the lower end position of tooth bar, constitutes the engaging structure of T-shaped shape, and function has been gearing.Gear adopts the bearing method to be installed in the lower-left end position of fixed mount, constitutes conjuncted structure, and function has been a fixation.The chalk platform adopts clinching method to be installed in the lower position of fixed mount, constitutes the conjuncted structure of " U " word shape, and function has been to put the chalk effect.Blackboard adopts contact method to be installed in the medium position of pulley rail, constitutes the conjuncted structure of T-shaped shape, and function has been the slip effect.The pulley rail adopts screw method to be installed in the end positions of fixed mount, constitutes conjuncted structure, and function has been the guide rail effect.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has been compared an advantage and improvement with original blackboard;
The first, because the utility model designed pinion and rack in technical scheme, so can blackboard movable up and down; Thereby the teacher that just can more effectively solve different heights uses the problem of blackboard inconvenience.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the work structuring schematic diagram of novel elevating blackboard of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 blackboard, 2 tooth bars, 3 fixators, 4 gears, 5 chalk platforms, 6 fixed mounts, 7 pulley rails
In the optimum implementation of novel elevating blackboard of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: as shown in the figure, novel elevating blackboard of the present utility model.Mainly constitute by blackboard 1, tooth bar 2, fixator 3, gear 4, chalk platform 5, fixed mount 6, pulley rail 7.Blackboard 1 adopts screw method to be installed in the back position of tooth bar 2, constitutes the conjuncted structure of T-shaped shape, and function is to serve to spur.Tooth bar 2 adopts contact method to be installed in the end position of fixator 3, constitutes T-shaped shape contact structures, and function has been a fixation.Tooth bar 2 adopts contact method to be installed in the guide rail position of fixed mount 6, constitutes the anti-body structure of a shape, and function has been to lead action to use.Gear 4 employing methods of engagement are installed in the lower end position of tooth bar 2, constitute the engaging structure of T-shaped shape, and function has been gearing.Gear 4 adopts the bearing method to be installed in the lower-left end position of fixed mount 6, constitutes conjuncted structure, and function has been a fixation.Chalk platform 5 adopts clinching method to be installed in the lower position of fixed mount 6, constitutes the conjuncted structure of " U " word shape, and function has been to put the chalk effect.Blackboard 1 adopts contact method to be installed in the medium position of pulley rail 7, constitutes the conjuncted structure of T-shaped shape, and function has been the slip effect.Pulley rail 7 adopts screw method to be installed in the end positions of fixed mount 6, constitutes conjuncted structure, and function has been the guide rail effect.
Its dynamic structure: in force:
According to transmission principle, its blackboard 1 acts on tooth bar 2 by gear 4, thereby finishes the task of lifting.So just realized the purpose of this utility model.Thereby the teacher that just can solve different heights uses the problem of blackboard inconvenience.
Below by using method, the utility model is done more detailed description:
The novel elevating blackboard of this utility model is work like this:
In use, when needs are regulated height, transmitting gear 4.According to transmission principle, its blackboard 1 acts on tooth bar 2 by gear 4, thereby finishes the task of lifting.
Realize that preferred plan of the present utility model is is material with the iron and steel, utilize the basic equipment of iron and steel factory, take to produce by batch in batches, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
