Abstract
The utility model relates to a study article, in particular to a telescopic school desk, which comprises a desk top and desk legs, wherein the desk top and the desk legs are connected through a connecting element, the lower part of the connecting element is provided with a connecting element chute, the upper part of each desk leg is provided with a desk leg chute, and the upper part of each desk leg is fixedly connected with the lower part of the connecting element through a screw bolt. The screw bolt simultaneously passes through the connecting element chute and the desk leg chute, and one end of the screw bolt is provided with a screw nut with the fastening effect. The telescopic school desk has the advantages that the ascending and descending structure is simple, the ascending and the descending of the school desk can be realized through utilizing the chute and screw bolt structure, and the problem that during the height regulation of the school desk with a through hole structure in the prior art, a through hole of the connecting element cannot be accurately aligned with a through hole arranged in the school desk is solved.
Description
Technical field
The utility model relates to a kind of study article, is a kind of telescopic desk specifically.
Background technology
Present desk is the earliest from all directions table in the school, be used for school, the functional dimension standard of desk-bench, anthropological measuring data and the special investigation in recent years of Main Basis China, desk of today mainly contain the solid wood desk, steel is moulded desk and rubber and plastic desk desk, and wherein the solid wood desk is easy to process, material is weedtree, wasting a large amount of timber, and be not durable, is still at present that the middle and primary schools of a lot of poverty-stricken areas adopt.Because the desk-bench height is fixed, replaced by the adjustable desk of steel-plastic structure gradually.It is generally highly adjustable that steel is moulded desk, and the relevant firmware up-down adjustment between slide-bar by table leg plays regulates the desk height, satisfies school and Students ' Demand with this.Such desk is mainly steel-plastic structure, and desktop is melamine plate, and table leg is steel pipe fitting, and the relevant connection above ground portion has the plastic cap protection.The rubber and plastic desk mainly adopts rubber-plastic alloy, and through mechanical compression molding school desk and chair product, this series products mostly is fixed structure, and is highly non-adjustable, but because material therefor is special, material is better, and durable convenient also obtains some schools and adopts.
Steel is wherein moulded desk due to highly can lifting, extensively be subjected to the welcome of school, but mostly the structure of moulding the desk lifting due to existing steel is by a lifter plate, a pin to be connected with desktop, and the steel construction at lifter plate place is for supporting desktop and the purpose that realizes lifting, the volume setting is all larger, and lifting is all to fix by a plurality of through holes and screw are set, so manufacturing cost is high, and lifting structure is more complicated, is difficult for realizing elevating function.
Be CN88200422 as number of patent application, the applying date is 1988-01-22, and name is called the utility model patent of " combination desk and chair ", and its technical side is: combination desk and chair, the desk and chair that lift in height is adjustable.Comprise duplex desk, two seats and four leg I-beam five fulcrum supports.3 adjustable connections of lifting of desk and support, seat and adjustable connection of support single-point lifting.The desk lifting of above-mentioned patent remains according to existing lifting structure, and a plurality of hole and screws side by side carry out the height adjusting, and lifting structure is more complicated, is difficult for realizing elevating function.
Summary of the invention:
More complicated for the lifting structure that existing desk exists, be difficult for realizing the elevating function problem, the simple telescopic desk of a kind of lifting structure is now proposed, its technical scheme is as follows:
A kind of telescopic desk comprises desktop and a table pin, it is characterized in that, desktop and a table pin are connected by connector, are provided with the connector chute in the connector bottom, and the top of a pin is provided with a pin chute, and a pin top and connector bottom are bolted to connection.
Described bolt passes connector chute and table pin chute simultaneously, and bolt one end is provided with the nut that plays the role of fastening.
Described connector chute is measure-alike with table pin chute.
Described connector and the adjacent setting of table pin.
The utility model advantage is:
1, the utility model lifting structure is simple, utilizes chute and bolt arrangement can realize the lifting of desk, has avoided former through-hole structure when adjusting the desk height, can't be accurately with the problem of through hole and the through-hole alignment on desk of connector.
2, sliding groove structure processing is simple, and relates to the parts manufacturing cost reduction of lifting.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model side view.
In accompanying drawing, desktop 1, table pin 2, connector 3, connector chute 4, table pin chute 5, bolt 6.
The specific embodiment
Embodiment 1
Telescopic desk comprises desktop 1 and a table pin 2, and desktop 1 and a table pin 2 are connected by connector 3, is provided with connector chute 4 in connector 3 bottoms, and the top of a pin 2 is provided with a pin chute 5, and pin 2 tops are fixedly connected with by bolt 6 with connector 3 bottoms.Described bolt 6 passes connector chute 4 and table pin chute 5 simultaneously, and bolt 6 one ends are provided with the nut that plays the role of fastening.The utility model lifting structure is simple, utilizes chute and bolt 6 structures can realize the lifting of desk, has avoided former through-hole structure when adjusting the desk height, can't be accurately with the problem of through hole and the through-hole alignment on desk of connector 3.
Telescopic desk comprises desktop 1 and a table pin 2, and desktop 1 and a table pin 2 are connected by connector 3, is provided with connector chute 4 in connector 3 bottoms, and the top of a pin 2 is provided with a pin chute 5, and pin 2 tops are fixedly connected with by bolt 6 with connector 3 bottoms.Bolt 6 passes connector chute 4 and table pin chute 5 simultaneously, and bolt 6 one ends are provided with the nut that plays the role of fastening.Connector chute 4 is measure-alike with table pin chute 5.Connector 3 and the adjacent setting of table pin 2.The utility model lifting structure is simple, utilizes chute and bolt 6 structures can realize the lifting of desk, has avoided former through-hole structure when adjusting the desk height, can't be accurately with the problem of through hole and the through-hole alignment on desk of connector 3.
