Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ",
" connected " etc., was both directly connected to including a certain component and another component, also passed through miscellaneous part and another portion including a certain component
Part is connected.
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.
As shown in Figure 1-Figure 3, this application provides a kind of portable sample prescription frame of plication, including the first edge strip that structure is consistent
1st, the second edge strip 2, the 3rd edge strip 3, the 4th edge strip 4 and rivet 5, second edge strip 2 are placed on first edge strip 1, its
One end is articulated and connected with first edge strip 1 by rivet 5, and the 3rd edge strip 3 is placed on second edge strip 2, one
End is articulated and connected with described second edge strip, 2 one end by rivet 5, and the 4th edge strip 4 is placed on the 3rd edge strip 3, its both ends
It is articulated and connected respectively by 3 one end of rivet and the 3rd edge strip, 1 one end of the first edge strip.
When folding square-like square frame, in 6 direction of diagonal that sample prescription frame is formed along the first edge strip 1, the 4th edge strip 4
Folding, four sides is collapsed, four sides are collapsed into " V " type, are then tightened again, become linear type inward naturally.
Preferably, there is provided a kind of structure of specific sample prescription frame, the sample prescription frame is the square-like square frame of 1m × 1m, described
First edge strip 1, the second edge strip 2, the 3rd edge strip 3, the 4th edge strip 4 are made of the iron plate of long 105cm, thickness 0.5cm, width 2.5cm,
Every iron plate makes a hole at the 1.25cm of front and back end, and aperture is 1cm by preparing 4 rivets, each a diameter of
0.8cm, is highly 1.0-1.2cm, is attached, and the gap that 1-2mm is left between two edges is rotated with facilitating.
Preferably, as shown in Figure 4, Figure 5, the first edge strip 1 of the sample prescription frame, the second edge strip 2, the 3rd edge strip 3, the 4th side
Bar 4 is made of iron material, and material is solid, including first 7, second 8 and connecting rod 9, the first tension spring 10, the second tension spring
11st, locking nut 12, described first 7 and second 8 cavity for being both provided with a side opening, connecting rod 9 and the cavity phase
It is used cooperatively, the cavity and the cavity of second 8 of first 7 is inserted at both ends respectively, is slidably connected with the cavity, the first tension spring
10th, the second tension spring 11 is respectively arranged in the cavity of first 7 and in the cavity of second 8, and one end of the first tension spring 10 with
One end connection of connecting rod 9, the other end are connected with first 7 inside cavity, one end of the second tension spring 11 and one end of connecting rod 9
Connection, the other end are connected with second 8 inside cavity, and threaded hole is provided with the wall of first 7 cavity and second 8 cavity,
Locking nut 12 fixes connecting rod through the threaded hole so that with first and second opposite move does not occur for connecting rod
It is dynamic.
Due to selecting solid ferrous material to be used as making material, weight is larger, in view of this, setting cavity body structure
In the case where guarantee is solid, mitigate dead weight.Further, since existing sample prescription frame is usually the square-like of fixed 1m × 1m
Square frame, therefore, when adjustment region size is needed, can not use, and therefore, using connecting rod stretching structure, configure tension spring,
After area size is regulated, work, after the completion of work, unclamp locking nut, under the action of tension spring, length contracts automatically
It is small, it is easy to carry.
On the basis of the above, for the ease of adjusting the length of edge strip, accurately measured, on 9 surface of connecting rod
It is marked with scale.
As shown in fig. 6, due to reducing dead weight, correspondingly, its stability is necessarily affected, in order to increase the steady of device
It is qualitative, the lower face of nethermost first edge strip 1 is being provided with engaging lug 13, inserted block is hinged with by the engaging lug 13
14.When use, by inserted block 14 from the state parallel to edge strip, the state perpendicular to edge strip is changed to, inserted block is inserted into ground
It is fixed.
Underground is inserted into for the ease of inserted block, the inserted block 14 is wedge shape.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
