Description
Technical field
This utility model belongs to articles for children field, more particularly to a kind of easel support connection structure.
Background technology
Drawing board, is a kind of conventional drawing tools, particularly Drawing board for children, has obtained increasing in the modern life
Use, the head of a family increasingly payes attention to the culture of the painting ability to child, but because the height of child is different or the custom of picture
Different, so sometimes for the regulation that drawing board is entered with line height, and existing drawing board is to reach the purpose of regulation, often
Screw rod and nut are used as easel support connection structure, but, screw rod often has one end and exposes, and nut also can be as support
Outer surface, one end of screw rod is more sharp, and nut is also steel product, relatively harder, is so easy to hurt use
Child, so from the point of view of safety, such drawing board is simultaneously dangerous.
Utility model content
This utility model, in order to overcome the deficiencies in the prior art, provides a kind of easel support safe, easy to use
Attachment structure.
To achieve these goals, this utility model employs the following technical solutions：A kind of easel support connection structure, including
Screw rod and and screw rod that second support that first support is matched with first support, the first nut are matched with the first nut
The second nut of matching it is characterised in that：Described first support is provided with the through hole for installing described first nut, and first
Nut is coordinated with the inwall rotation stop of this through hole, so so that the first nut is built in first support, thus safer.
Further, the internal diameter of described through hole is less than the external diameter of the first nut, thus the first nut being is convenient
Install in first support, in addition the first nut is also more mated with the degree of occlusion of first support.
Further, described first nut outer surfaces are provided with projection, can make through hole in first support for first nut
Interior fixation, so that the first nut is difficult to come off from support.
Further, described second support is provided with the chute being available for through screw rod, can assign screw rod as a fixing point,
Realize second support moving up and down with respect to first support.
Further, described first support is wood materials so that the first nut and first support can be more preferable
Fixing.
Further, described second nut is externally provided with protective case, and second nut that makes that can be convenient unclamps, tightens,
Meanwhile, also function to protect the effect of screw rod end, make screw rod end be not easy to hurt user, also more attractive in appearance.
Further, described projection is pyramid shape, and the first nut and first support can be made preferably to fix.
In sum, this device need not put into substantial amounts of artificial, and technical requirements are not high, easy and simple to handle.By permissible
Just can be with the purpose of easy adjustment height of drawing board, in addition, the screw rod of this device is designed with protecting by the cooperation of screw rod and nut
Set, is not easy to hurt user with the sharp parts guaranteeing screw rod end, also makes drawing board also more attractive in appearance simultaneously.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural profile schematic diagram of the present utility model.
Fig. 3 is the first nut of the present utility model and the structural representation of screw rod cooperation.
Specific embodiment
In order that those skilled in the art are better understood from this utility model scheme, real below in conjunction with this utility model
Apply the accompanying drawing in example, clear, complete description is carried out to the technical scheme in this utility model embodiment.
As Figure 1-3, a kind of easel support connection structure, including first support 1, second support 2, the first nut 3, spiral shell
Bar 4 and the second nut 6.First support 1 is provided with through hole 5, and the first nut 3 outer surface is provided with projection, and this raised shape is permissible
It is pyramid shape, triangular pyramid, semicircle or other shapes；The external diameter of the first nut 3 is matched with through hole 5 internal diameter, first
Make the first nut 3 and first support 1 fixing in the presence of nut 3 convex outer surfaces.So make the first nut 3 completely first
In support 1, there is no unnecessary partial denudation outside, more safe, in addition, the first nut 3 is also preferably stung with first support 1
Close, be difficult to drop.
Screw rod 4 is matched with the first nut 3, second support 2, and second support 2 is provided with and is available for through screw rod 4 chute, sliding
The width of groove is slightly larger than the width of screw rod 4.Screw rod 4 end is provided with the second nut 6 matching with screw rod 4, outside the second nut 6
It is provided with protective case 7, the shape of protective case 7 can be triangle, circle etc..Screw rod 4 length is more than first support 1 and second support
2 width sum, during the chute of the first nut 3 in screw rod 4 is through first support 1 and second support 2, the end of screw rod 4
Understand some and extend second support 2 outer surface, the end of screw rod 4 is coordinated with the second nut 6, make second support 2 pass through to slide
Groove is connected with first support 1, and second support 2 can move up and down along chute direction.It is provided with protective case 7, protection outside second nut 6
Set 7 is provided with groove, and the depth of protective case 7 upper groove extends the length of second support 2 outer surface more than the end of screw rod 4,
The width of protective case 7 is more than the width of second support 2 upper hopper chute.
Specifically, first support 1 is provided with through hole 5, and the internal diameter of through hole 5 is slightly less than the external diameter of the first nut 3, due to
One support 1 is wood materials, by the effect of external force, the first nut 3 is knocked in first support 1, due to the first nut 3 outward
Side is provided with the projection of pyramid shape, and projection just can be matched with first support 1, by the effect of gmatjpdumamicss, makes the first nut 3 solid
It is scheduled in first support 1.Length due to screw rod 4 is more than the width sum of two stands, when screw rod 4 passes through first support 1 and the
During two supports 2, the end of screw rod 4 is understood some and is extended second support 2 outer surface, because the end of screw rod 4 is more sharp,
It is easy to hurt the people using drawing board during using easel, in addition, drawing board can coordinate drawing paper to use, drawing paper is to compare
Thin, the end of the screw rod 4 being therefore exposed also easily causes the breakage of drawing paper.Therefore one protective case of this practical design
7, protective case 7 is provided with groove, and the depth of protective case 7 upper groove extends second support 2 outer surface more than the end of screw rod 4
Length；Such setting can be very good to guarantee the end of screw rod 4, is difficult to hurt user, is not easy to hurt drawing paper simultaneously.
In addition, when the second nut 6 unclamps from screw rod 4, by the chute in second support 2, can arbitrarily adjust second
Support 2 is with respect to the position in first support 1, thus reaching the purpose adjusting easel height；When the second nut 6 is on screw rod 4
When tightening, the second nut 6 can produce pressure and make first support 1 fixing with second support 2, thus reaching fixing easel height
Purpose, therefore unclamps, tightens for convenient second nut 6 that makes, be provided with protective case 7, make first support outside the second nut 6
Also dismount more convenient between 1 and second support 2.
Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.
Based on the embodiment in this utility model, those of ordinary skill in the art are obtained under the premise of not making creative work
Every other embodiment, all should belong to the scope of this utility model protection.
