Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of adjusting blackboard, as shown in Figure 1, including the first blackboard body 1 and the second blackboard sheet
Body 2 opens up fluted 3 in first blackboard body 1, and 3 two sides of groove are equipped with guide rail 4；As shown in Fig. 2, being embedded in 2 guide rails 4
Idler wheel 5, as shown in figure 3, the top of the second blackboard body 2 is connect by shaft a2-1 with idler wheel 5；As shown in figures 1 and 3,
The side wall of one blackboard body 1 is equipped with support arm 6, and the side of the second blackboard body 2 is equipped with flange 2-2, opens up adjusting on flange 2-2
Slot 7, support arm 6 can be caught in regulating tank 7.
As shown in figure 3, support arm 6 includes that fixed part 6-1 and rotation support rod 6-2, fixed part 6-1 are installed in the first blackboard
The side wall of ontology 1；It is L-shaped to rotate support rod 6-2；Rotation one end support rod 6-2 is connect by shaft b6-3 with fixed part 6-1,
The other end of rotation support rod 6-2 is caught in regulating tank 7.Fixed part 6-1 setting occupies when in use in the first blackboard body 1
It occupies a narrow space, while not keeping off the sight of viewer.It is L-shaped to rotate support rod 6-2, when in use, rotates one end energy of support rod 6-2
Enough by shaft b6-3 rotary motion on fixed part 6-1, the other end of rotation support rod 6-2 can be caught in regulating tank 7, rise
To limit fixed function, the second blackboard body 2 is enable to adjust different height.
Regulating tank 7 includes through slot 7-1, through slot 7-1 along flange 2-2 length to setting.The side of through slot 7-1 is equipped with multiple
Bayonet 7-2, and each bayonet 7-2 and through slot 7-1 is integrated.The design of through slot 7-1 enables to rotation support rod 6-2 to be easy to stretch
Enter in through slot 7-1, the design of bayonet 7-2 enables to rotation support rod 6-2 that can be caught in 7-2, and plays better limit
Position effect.The more bayonet 7-2 setting the more intensive, then adjustable angle change gradient is smaller every time.
As shown in Fig. 1 and 3~5, support arm 6 is in the ipsilateral setting 1~2 of the first blackboard body 1.When the height of user is solid
Periodically, it is preferred to use a support arm 6；When teaching object is different height groups, it is preferred to use two support arms 6；With this
Mode come adapt to people of different heights group.
Second blackboard body 2 can be embedded in groove 3.Blackboard can be made to be adjusted to vertical state and original height after having write
Degree, do not influence student look at the blackboard on content.
Handle 8 is additionally provided in second blackboard body 2.Push-and-pull blackboard is facilitated to adjust, it is relatively labor-saving quick.
As shown in figure 4, a kind of initial use state for adjusting blackboard of the utility model, the first blackboard body 1 are fixed on wall
On wall, the second blackboard body 2 vertically in the groove 3 of the first blackboard body 1, and the rotation support rod 6-2 of support arm 6 against
Wall is placed, and space is not take up.
A kind of workflow for adjusting blackboard of the utility model: as shown in figure 5, when needing the height adjusted or putting blackboard
Usually, pull handle 8 pulls the second blackboard body 2 towards obliquely downward, when blackboard being made to reach required state, rotational support arm
6, so that the rotation support rod 6-2 of support arm 6 is protruded into the through slot 7-1 in regulating tank 7, and be caught in any bayonet in bayonet 7-2
In, fixed bearing effect can be realized to the second blackboard body 2.When needing to continue to adjust, then it can continue pivotal support arm 6
Support rod 6-2 skid off in the bayonet 7-2 being caught in, enter in the through slot 7-1 of regulating tank 7, then adjust blackboard position or
Angle makes rotation support rod 6-2 be caught in suitable bayonet 7-2.
If support arm 6 is two groups, using before one group, another group of rotation support rod 6-2 should wherein be rotated to
Initially against the state of wall, another group is then reused, application method is consistent with one group of support arm 6.
By the above-mentioned means, support arm 6 is caught in tune by pivotal support arm 6 by a kind of adjusting blackboard of the utility model
It saves in slot, the second blackboard body 2 is fixed；The height of blackboard can be adjusted, to adapt to the use of different height crowds；This is practical
Novel a kind of adjusting blackboard, after needing that blackboard is adjusted to proper angle or is laid flat when writing on the blackboard, it may not be necessary to lift arm and write
Word, the laborsaving strain for reducing arm and neck shoulder, prevents arm and neck shoulder occupational disease；Easy to use, structure is simple.
