Abstract
The utility model discloses a kind of blackboard frame connecting structures, vertical rack including being fixed on blackboard on both sides, the bottom level of the vertical rack is equipped with the supporting rod of strip, supporting rod is vertical with vertical rack, the bottom of the vertical rack is fixed with connector, it is respectively equipped with bolt positioned at the front and back of vertical rack on the connector, and is connect with supporting rod by bolt；The centerline parallel of the bolt and supporting rod and in same perpendicular, the both sides of the connector extend to the middle part of supporting rod both sides, and the side elevation of the lower surface of connector is overlapped with the side elevation of the top half of supporting rod.The utility model is simple in structure compared with prior art, easy for installation, and the scattered packaging of each section and transport are also very convenient.Vertical rack rotation, crooked situation occur when being effectively prevented installation, are easy the bolt hole in connection sheet and supporting rod being aligned, facilitate installation and fixation.
Description
Technical field
The utility model is related to office appliances, more particularly to blackboard frame connecting structure.
Background technology
Blackboard is the writing implements such as common teaching, office, living when some Mobile Teachings, office, session discussing
The dynamic place carried out, place will not possess fixed blackboard as school.At this point, just needing to place movable type on the top of the shelf
Blackboard is as interim writing implement.
Existing easel can be bolted with Fast Installation, all parts.But for larger-size blackboard
Very inconvenient when the fixed installation for the supporting rod that frame, vertical rack and bottom are used to support, existing is typically vertical branch
Frame is hollow tubular, is vertically equipped with one section of inserted link in advance at the middle part of supporting rod, inserted link is inserted into vertical rack when installation, so
The two is fixed after the inserted link of vertical rack and its inside by bolt afterwards.Such fixed form is for vertical rack
Structure requires, it is necessary to be hollow tubulose, and advance fixed one section of inserted link on supporting rod, in transportational process also because
It is not easy to pack for protruding for inserted link.
Utility model content
In order to overcome drawbacks described above, the utility model provides a kind of blackboard frame connecting structure, to the structure of vertical rack
It does not require, without other structures on supporting rod.
The utility model is achieved through the following technical solutions：
Blackboard frame connecting structure, including it is fixed on the vertical rack of blackboard on both sides, the bottom level of the vertical rack is set
There is the supporting rod of strip, supporting rod is vertical with vertical rack, and the bottom of the vertical rack is fixed with connector, the connection
It is respectively equipped with bolt positioned at the front and back of vertical rack on part, and is connect with supporting rod by bolt；The bolt and supporting rod
Centerline parallel and in same perpendicular, the both sides of the connector extend to the middle part of supporting rod both sides, connector
The side elevation of lower surface is overlapped with the side elevation of the top half of supporting rod.
The cross section of the supporting rod is in oblong.
The connector is oval sheet, the centerline parallel of longer center line and supporting rod and same vertical
In plane.
Connector both sides extension is bent along supporting rod both side surface and is attached to supporting rod surface.
The both ends of the supporting rod bottom are respectively equipped with wheel.
The utility model is simple in structure compared with prior art, easy for installation, and each section is scattered to pack and transport also very
It is convenient.The connection structure of the utility model is firm in addition to easy for installation, while very, and connection sheet envelopes the first half of supporting rod
Point, vertical rack rotation, crooked situation occur when being effectively prevented installation, are easy the bolt hole in connection sheet and supporting rod
Alignment, facilitates installation and fixation.

Specific implementation mode
As shown in Figure 1, the utility model includes the vertical rack 2 for being fixed on 1 both sides of blackboard, the bottom of the vertical rack 2
Portion's level is equipped with the supporting rod 3 of strip, and supporting rod 3 is vertical with vertical rack 2, and the bottom of the vertical rack 2 is fixed with company
Fitting 4 is located at the front and back of vertical rack 2 on the connector 4 and is respectively equipped with bolt 5, and connect with supporting rod 3 by bolt 5；
The centerline parallel of the bolt 5 and supporting rod 3 and in same perpendicular, the both sides of the connector 4 extend to support
The side elevation at the middle part of 3 both sides of bar, the lower surface of connector 4 is overlapped with the side elevation of the top half of supporting rod 3.
The cross section of the supporting rod 3 is in oblong.
The connector 4 is oval sheet, the centerline parallel of longer center line and supporting rod 3 and same perpendicular
In straight plane.
4 both sides extension of the connector is bent along 3 both side surface of supporting rod and is attached to 3 surface of supporting rod.
The both ends of 3 bottom of the supporting rod are respectively equipped with wheel 6.
