Abstract

The utility model relates to an improved structure on pen grooves of whiteboards, which is mainly composed of a whiteboard main body, an outer framework and a pen groove. The outer side of the bottom edge of an upper framework is provided with a joint part of a circular groove. The bottom edge of the outer side of joint part is provided with a saddle part in parallel. The upper edhe of the back part of the pen groove is provided with a longitudinal column. The column can be inserted into a joint part of a lower framework. The bottom edge of the back part of the pen groove is provided with a convex part. When the convex part id combined, the convex part can be exactly buckled on the saddle part of the lower framework. When the utility model is not used, the pen groove can be folded upwards for reducing package volume. Combination of the pen groove and the lower framework is firmer and more durable and is not easy to be folded upwards or desquamated.

Description

The improvement structure of a blank groove

The utility model relates to cultural tools, particularly the blank of a display text picture groove structure.

A known now blank groove structure please referring to shown in Fig. 4,5, mainly includes blank 1, and an outside framework 2 and a groove 3 are formed; Have the section configuration of a groove 31 at a groove rear, directly be buckled in underframe 21 bottoms by groove 31 during combination, form with screw 4 suitable lockings again corresponding to underframe 21.

The disappearance of above-mentioned known structure: a groove of this blank be because of folding, and makes usually time spent collection very not inconvenient, especially when goods packing, more can improve cost of transportation because of the increase of Packing Capacity.

The purpose of this utility model is to provide a kind of groove upwards to amount at any time and is attached to whiteboard surface, be convenient to collection and reduce Packing Capacity, and intensity is big, the improvement structure of the blank groove that steadiness is good.

For reaching above-mentioned purpose, the improvement structure of a blank of the present utility model groove mainly is made up of an external framework of white plate and a groove; The joint portion that wherein has a circular groove in the underframe root edge outside of outside framework, and the root edge outside the joint portion is answered the parallel saddle that is provided with; The rear upper limb of groove has a horizontal cylinder, but the cylinder intercalation and has a protuberance at a groove rear root edge in the joint portion of underframe, and protuberance just can be buckled in the saddle of underframe when combination.

The utility model has the advantages that:

1, a groove not the time spent can upwards fold, take up room or Packing Capacity with minimizing.

2, can firmly engage between a groove and the underframe, and have a saddle, therefore, a groove bearing strength is big, and steadiness is good.

Below in conjunction with accompanying drawing structure technology feature of the present utility model is described further:

Description of drawings:

Fig. 1 is a stereogram of the present utility model.

Fig. 2 is a section constitutional diagram of the present utility model.

Fig. 3 is another kenel schematic diagram of Fig. 2.

Fig. 4 is known blank constructing stereo exploded view.

Fig. 5 is the section constitutional diagram of known structure.

See also shown in Fig. 1,2,3, the improvement structure of a blank of the present utility model groove, mainly by blank body 1, an outside framework 2 and a groove 3 are formed; The joint portion 23 that wherein has a circular groove in underframe 22 root edges of outside framework 2 outside, and in the joint portion 23 outsides the multiple level land of root edge be provided with a saddle 24; The rear upper limb of groove has a horizontal cylinder 32, but cylinder 32 intercalations and have a protuberance 33 at a groove 3 rear root edges in the joint portion 23 of underframe 22, and protuberance 33 just can be buckled in the saddle 24 of underframe 22 when combination.

When above-mentioned tectonic association uses, groove 3 mat cylinders 32 intercalations are in the joint portion 23 of underframe, groove 3 can upwards fold along the opening 231 of the joint portion 23 of underframe 22, and its groove face 34 can be relied on the blank 1, the volume when reducing its occupation space with packing; In addition, when a groove 3 combines with underframe 22, the cylinder 32 of a groove 3 be whole piece by joint portion 23 clamping that coats of underframe, so the intensity of a groove 3 is preferable, comparatively sturdy and durable; Again, turn down when using at a groove 3, but its trailing edge protuberance 33 of mat be buckled in the saddle 24 of underframe, collude by saddle 24 leading edge places 241 and be held in protuberance 33 inboard turnings 331, just a groove 3 can not flip because of the people is casual and upwards turn down or upspring, and its article of putting are dropped.

Claims

The improvement structure of a kind of blank groove, mainly by the blank body, an outside framework and a groove are formed; It is characterized in that: the underframe root edge outside of outside framework has the joint portion of a circular groove, and answers the parallel saddle that is provided with at the root edge in the outside, joint portion; The rear upper limb of groove has a horizontal cylinder, but the cylinder intercalation and has a protuberance at a groove rear root edge in the joint portion of underframe, and protuberance just can be buckled in the saddle of underframe when combination.
