Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection relationships not singly refer to that component directly connects, and referring to can be according to specific implementation situation, by adding or reducing connection
Auxiliary, Lai Zucheng more preferably connection structure.Each technical characteristic in the invention, under the premise of not conflicting conflict
It can be with combination of interactions.
Referring to figs. 1 to Fig. 6, this is the embodiment of the present invention one, specifically:
A kind of pull-type foldable wallboard, including the cell board 2 that drawing and pulling type guide rail, at least two pieces are vertically arranged, drawing and pulling type is led
Rail includes at least hollow connecting tube 10 that is successively arranged of two pieces, the hollow laterally setting of connecting tube 10, the head of hollow connecting tube 10
In the tail portion of adjacent hollow connecting tube 10, the tail portion of hollow connecting tube 10 is equipped with the connecting shaft 11 being vertically arranged, single
First plate 2 is corresponded with connecting shaft 11, and cell board 2 is rotatably attached with connecting shaft 11.
Structure of the invention includes folded state and unfolded state.When folded state, mobile hollow connecting tube 10 makes to have leisure
The tail portion of heart connecting tube 10 is close to each other, and drawing and pulling type guide rail shortens, and connecting shaft 11 is also close to each other simultaneously with cell board, and rotation is single
First plate, cell board is mutually close in this way, the positional relationship between cell board is similar to be stacked.It is mobile when unfolded state
Hollow connecting tube 10 is located remotely from each other the tail portion of hollow connecting tube 10, the elongation of drawing and pulling type guide rail, connecting shaft 11 and cell board
It is located remotely from each other simultaneously, rotary unit plate, cell board is successively laid on same perpendicular.Therefore it may only be necessary to by simple
It takes out to act the switching that can be completed between the folded state and unfolded state of the pull-type foldable wallboard, the pumping in the structure
Pull-type guide rail can provide higher intensity, and cell board can provide masking, without building steel frame construction again and being laid with plate
Or cloth, without installing a large amount of connectors at the scene, which is used as the large wall panel of large-scale temporary building, can reduce large size
The dismounting workload of temporary building, time-consuming, cost of labor etc..
Connecting shaft 11 can by weld, be spirally connected etc. modes old place that on the lateral wall in hollow connecting tube 10, even
Spindle 11 should not protrude into the too long of distance of hollow connecting tube 10, and one avoids connecting shaft 11 from hindering between adjacent hollow connecting tube 10
It is flexible.
Further, the quantity of the drawing and pulling type guide rail is two pieces, the setting symmetrical above and below of two pieces drawing and pulling type guide rail, two pieces pumping
The connecting shaft 11 of pull-type guide rail is corresponded with cell board 2, and cell board 2 is rotatably attached with connecting shaft 11.When cell board 2
Height it is larger when, setting two pieces drawing and pulling type guide rail symmetrical above and below is conducive to the stabilization of 2 position of cell board.
Further, the upper and lower part of cell board 2 is equipped with casing 21, and connecting shaft 11 is equipped with bearing, and 21 sets of casing
It connects on bearing.By the connection between casing 21, bearing and connecting shaft 11, cell board 2 and connecting shaft can be swimmingly realized
11 rotation connection.
Further, the head of hollow connecting tube 10 is equipped with the first limiting stand 12 of outwardly convex, hollow connecting tube 10
Tail portion is equipped with inwardly protruded second limiting stand 13, and the outer end face of the first limiting stand 12 is set to the inner face of the second limiting stand 13
Outside.Firstly, since the outer end face of the first limiting stand 12 is set to the outside of the inner face of the second limiting stand 13, so the first limit
Platform 12 can prevent adjacent hollow connecting tube 10 to be disconnected with the cooperation of the second limiting stand 13;In addition, a hollow connecting tube
It can mutually be abutted between 10 the first limiting stand 12 and the inner wall of adjacent hollow connecting tube 10, the of a hollow connecting tube 10
Two limiting stands 13 can also be abutted mutually with the lateral wall of adjacent hollow connecting tube 10, be reduced between adjacent hollow connecting tube 10
Gap, when so that mutually moving between adjacent hollow connecting tube 10, hollow connecting tube 10 will not be collided mutually, be rocked.
Further, further include pulley 3, pulley 3 be set to the lower section of the tail portion of hollow connecting tube 10 and with hollow connecting tube
10 are connected, and the pulley 3 being connected with hollow connecting tube 10 is set to the outside of adjacent hollow connecting tube 10.Firstly, pulley 3 can reduce
When the structure switches between folded state and unfolded state and the friction on ground;In addition, since hollow connecting tube 10 is successively
It is arranged, so the bottom surface of each hollow connecting tube 10 is in same level, but rises one by one, by each pulley 3
Height is arranged to increase one by one, the difference in height of the bottom surface of each hollow connecting tube 10 can be balanced, so that the pull-type foldable wall
3 bottom of pulley of plate is set in same level.
It further, further include anticollison block 4, anticollison block 4 is set in connecting shaft 11, anticollison block 4 and adjacent hollow company
The tail end of adapter tube 10 abuts.Anticollison block 4 can be soft rubber material, buffer tail portion and the connecting shaft 11 of hollow connecting tube 10
Between collision.
Referring to Fig. 7, this is the embodiment of the present invention two, and the difference with above-described embodiment is:
It further, further include the installation axle 5 being laterally arranged, installation axle 5 is rotatably attached with connecting shaft 11, cell board
2 is affixed with installation axle 5.Cell board 2 is rotatably attached with connecting shaft 11 indirectly by installation axle 5, and in the structure, two pieces is taken out
The corresponding connecting shaft 11 in position can be an entirety on pull-type guide rail, and installation axle 5 is connected in connecting shaft 11, in this way, connection
Axis 11 can provide vertical supporting, power suffered by reduction unit plate 2.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are included in the claim of this application limited range.
