Description

A kind of desk for expanding desktop

Technical field

The present invention relates to education equipment technical field more particularly to a kind of desks for expanding desktop.

Background technology

Desk when learning as a kind of student essential equipment play great effect, desk usually by desktop, The compositions such as drawer and table leg, usually double desk and structure is single, function is simple when old-fashioned desk designs, are nowadays learned Raw to be often made with individual single desk, when build smaller use, is pleasant and cannot be easily caused the interference between student, Quiet studying space can be provided, although Modern desk is more humane since the learning tasks of nowadays student are numerous Weight, all kinds of data are various, therefore demand is often not achieved in single desk on usable floor area, causes students' union data such as books It places on the ground, this problem is solved.

Invention content

Use is not achieved the purpose of the present invention is to solve Modern desk usable floor area existing in the prior art is smaller The shortcomings that demand, and a kind of desk that expanding desktop proposed.

To achieve the goals above, present invention employs following technical solutions：A kind of desk for expanding desktop, including face Plate is symmetrically installed on the bottom wall of the panel there are four table leg, and drawer is equipped with jointly on the side wall of four table legs, described The both sides of panel are arranged with two expansion plates, and two expansion plates are mounted on multiple insert on the side wall of panel side Plate, offers multiple slots to match with plate on the side wall of the panel both sides, and each plate is plugged in pair It in the slot answered, is respectively mounted there are two the first mounting plate on two bottom walls for expanding plate, is located at two of homonymy described the Equal common rotation is connected with the first bull stick between one mounting plate, is equally symmetrically installed that there are two the on the bottom wall at the panel both ends One mounting plate, and it is equally rotatably connected to the first bull stick between two the first mounting plates of homonymy, it is located at two of homonymy Telescopic device is installed jointly, the telescopic device includes the first mother set and the first sub- stalk, institute on the side wall of first bull stick It states the one end of the first mother set far from the first sub- stalk to be mounted on the side wall for expanding the first bull stick on the downside of plate, first son The one end of stalk far from the first mother set is mounted on the side wall of the first bull stick on the downside of panel, and the first mother set is set in first It is mounted on fixed plate on the side wall of the outside of sub- stalk, first mother set and the first sub- stalk, is total between two fixed plates With spring is equipped with, two the second mounting plates are separately installed between the expansion board bottom wall and the lateral wall of table leg of homonymy, It is rotatably connected to the second bull stick between two second mounting plates of homonymy, is located at described in two expanded on the downside of plate It is mounted on the second mother set on the side wall of second bull stick, the bottom ends of two second mother sets is inserted with the second sub- stalk, two The bottom end of the second sub- stalk is installed on the side wall of the second bull stick on the outside of table leg.

Preferably, two second mother sets are threaded with thread bush jointly with the second sub- stalk one end close to each other, The top of two second sub- stalks is mounted on limiting plate.

Preferably, hook is installed on the side wall of one of them table leg.

Preferably, placing frame is installed jointly on the lateral wall of two table legs of homonymy.

Preferably, the bottom end of four table legs is mounted on rubber pad

Preferably, the roof of the panel offers cup placing groove and slot.

In the present invention, the expansion plate that the both ends of panel are installed by telescopic device can expand desk, and operation is as follows, It is mobile to expand plate and be inserted into the plate installed on plate is expanded in the slot that panel both ends open up, during plate is expanded in movement, The the first sub- stalk installed on the downside of panel is rotated around the first bull stick, expands the first mother set of installation on the downside of plate also around the One bull stick is rotated, while the first sub- stalk stretches in the first mother set, spring spring can the first mother set and the first sub- stalk it Between apply pulling force and can be tightened when plate is inserted into slot so that plate is closely connect with slot simultaneously, while the second mother The second bar rotation that set is installed around the second bar rotation for expanding installation on the downside of plate, the second sub bar on the outside of table leg, the Two sub bars are plugged in the second mother set, and the bottom end of the second mother set and the top of the second sub bar are equipped with thread bush jointly, screw The second mother set and the second sub bar can be fixed in thread bush, and the second mother set can be provided expanding plate after being fixed with the second sub bar Support force makes expansion plate is more firm to be spliced with panel, this outer hanging hook can be used for hanging school bag, and placing frame also can be to books Etc. data placed, further increase usable floor area, the cup placing groove being arranged on panel roof can prevent cup from surprisingly hitting , slot can store water-color paintbrush, avoid water-color paintbrush from tumbling and break.

The configuration of the present invention is simple is easy to use, is expanded to desktop compared to what existing desk can be consolidated easily, To solve the disadvantage of desk usable floor area deficiency, while the placement to cup and water-color paintbrush and other items is increased, improves desk It is functional.
