Invention content

Invention is intended to provide a kind of size adjustable tea table, to solve to manually adjust size of desktop mistake in the prior art Journey is cumbersome and adjustment after desktop position of centre of gravity change so that tea table the problem of easily turning on one's side.

The base case of the present invention is the adjustable tea table of size, including desktop and table leg, wherein：

The end of the desktop bottom surface is hinged with the increasing plate that can be rotated along desktop end, and the desktop top surface is close to increasing plate One end is equipped with the first electromagnet, and the increasing plate is equipped with magnetite corresponding with the first electromagnet position；

The desktop bottom surface is provided with the first groove, and the increasing plate is provided with the second groove that can be docked with the first groove level, First groove is equipped with the second electromagnet along the first electromagnet direction far from the inner wall for increasing plate side and can be with table leg successively The voltage sensitive sensor of contact, the inner wall of second groove far from desktop are equipped with third electromagnet and elasticity successively along desktop direction Part, the top of the table leg have ferromagnetism, and the table leg can move in the first groove and the second groove；The increasing plate of rotation It can be contacted with table leg top surface；

Control circuit is set in desk body, control circuit includes single-pole double-throw switch (SPDT), controller and indicator light,

Power cathode connects the non-moving end of single-pole double-throw switch (SPDT),

First moved end of single-pole double-throw switch (SPDT) is connect with the second electromagnet, and the second electromagnet is connected with the anode of power supply；

Second moved end of single-pole double-throw switch (SPDT) is connect with the first electromagnet, and the first electromagnet is connected with the anode of power supply；

Second moved end of single-pole double-throw switch (SPDT) is also connect with third electromagnet, and third electromagnet is connected with the anode of power supply；

Branch wherein where third electromagnet is disconnected, and two breakpoints connect the first conductive sheet and the second conduction respectively Piece, the first conductive sheet are located on the side that desktop can be bonded with increasing plate, and the second conductive sheet, which is located at, increases plate the first conductive sheet of correspondence Position；

The voltage sensitive sensor sends signal of turning on light for acquiring pressure of the table leg to voltage sensitive sensor, to controller；Control Device processed is used to receive the signal of turning on light of voltage sensitive sensor transmission, and indicator light is controlled to light.

The present invention basic principle be：When single-pole double-throw switch (SPDT) on tea table desktop connects the first moved end, table leg is located at table In first groove of plate bottom, and the circuit where the second electromagnet is conducting, and the second electromagnet is firmly sucked with iron Magnetic table leg top so that table leg will not move in the first groove, ensure that table leg is fixed position in the first groove； Table leg applies pressure so that controller is controlled under the action of the second magnetic field force of the second electromagnet to voltage sensitive sensor at this time Indicator light is lighted, and can inform that user's table leg has completely arrived at fixed position, table leg will not move；

When user feel the desktop of current tea table too it is small cannot meet the requirements when, single-pole double-throw switch (SPDT) connection second is moved End, the circuit turn-on where the first electromagnet are hinged due to increasing between plate and desktop, increase plate and correspond to the first electromagnet position Magnetite the first electromagnet the first magnetic field force effect under, drive increase plate rotated up along desktop so that electromagnet It is firmly attracting with magnetite, and then increase plate and fixed with table position；When increasing plate in place, increase on the second conductive sheet and desktop on plate First conductive sheet contacts, since switch at this time is to be closed, so the circuit turn-on where third electromagnet, third electromagnet Ferromagnetic table leg is generated and is directed toward the third magnetic field force of third electromagnet in itself, and the circuit where the second electromagnet breaks at this time It opens, the second electromagnet is zero to the second magnetic field force of table leg, therefore table leg is under the action of third magnetic field force, recessed along first Slot marches on towards the second groove docked with the first groove, and then the elastic component with the second groove inner wall contacts, and in third magnetic field Under the action of power, table leg applies elastic component the pressure for being directed toward third electromagnet so that elastic component compresses；

Third electromagnet is marched on towards as table leg leaves the second electromagnet, and the voltage sensitive sensor on the outside of the second electromagnet is not adopted Collect pressure of the table leg to voltage sensitive sensor, controller control indicator light extinguishes, and informs that the position legs of user at this time do not exist Initial position (close to the position of the second electromagnet)；

When single-pole double-throw switch (SPDT) is again coupled to the first moved end, the circuit where the first electromagnet disconnects, the first electromagnet The first magnetic field force no longer is generated to magnetite, that is to say, that increase the support that plate loses the first magnetic field force, and at this point, due to table leg In the second groove for increasing plate, so, table leg support at this time increases plate, increases plate not under gravity, along table Plate is swung；

Again because the circuit where third electromagnet is connected with switch, when switch disconnects, third electromagnet loses magnetic Property, the elastic component that was originally compressed applies table leg the elastic force of one the second electromagnet of direction, also, where the second electromagnet Circuit turn-on, the second electromagnet, which applies table leg, is directed toward the second electromagnet the second magnetic field force in itself, in elastic force and the second magnetic Under the collective effect of field force, table leg marches on towards the first groove of desktop bottom surface along the second groove, then continues to march on towards the second electromagnetism Iron, and then the voltage sensitive sensor on the outside of the second electromagnet is squeezed so that controller control indicator light is lighted again, informs user Table leg at this time has returned to initial position, and position is fixed；

As table leg leaves the second groove increased on plate, increase the support force that plate loses table leg, therefore increase work of the plate in gravity Under, swung along with desktop, when increasing plate is swung to below desktop bottom surface, increasing plate can be in contact with table leg, also, Increase plate to table leg apply the thrust to the second electromagnet direction so that table leg in the first groove movement speed faster, table Leg can reach the second electromagnet position faster；And since the second electromagnet is to the magnetic field force of magnetite on increasing plate, increase plate It is static to retrodeviate to the second electromagnet side, it avoids increasing edges of boards angles and collides with damage.

This base case has the beneficial effect that：(1) when user needs to expand desktop area, single-pole double-throw switch (SPDT) is pushed Connect with the second moved end, increase plate automatic rotary transfer to be spliced into the desktop of a bigger with desktop afterwards, when need reduce desktop area When, it is only necessary to so that switch disconnects, increase plate and be restored to the position to hang before, the tea table of this programme is convenient to use, saves people Power；

(2) in the present solution, when increasing plate pieces together the desktop to form bigger with desktop, table leg is automatically along the first of desktop bottom surface Groove is shifted in the second groove for increasing plate, so as to further provide holding power to increase plate, improves the stationarity of desk body；

(3) this programme, when increasing plate rotation scrabbles up more large table surface as desktop, the center of gravity of entire desk body is moved to plate direction is increased It is dynamic, and the table leg that the third electromagnet of the second groove is shifted to along the first groove is moved to increasing plate direction, avoids entire desk body side It turns over, enhances the stability of desk body；

(4) in the present solution, single-pole double-throw switch (SPDT) pushes the first moved end from the second moved end, it is not to decline immediately to increase plate, and It is to decline after table leg is moved to the first groove from the second groove, the reaction time for giving user certain after switch closure, far From the i.e. increasing plate that will decline, avoid declining the increasing plate swung and wound user (such as the child in family)；

(5) whether lighting, inform whether user's table leg has set back by indicator light in this programme, switch is in During off-state, indicator light is not lighted, then can judge table leg not in situ；Whether the design determines desk body convenient for user It needs to detect and detect whether in place；

(6) in the present solution, when single-pole double-throw switch (SPDT) connects the first moved end, increase plate to desktop inner inclination, user is avoided to make With it is careless when scratch increasing plate, cause to increase the damage of edges of boards angles；

(7) table leg can move in the first groove and the second groove in this programme, also recessed by first while movement Dust stratification in slot and the second groove is removed, and keeps the clean and tidy of the first groove and the second groove.

Further, desktop is installed with clockwork spring close to the both ends for increasing plate side, and soft band is equipped between the clockwork spring, Described soft band one end and clockwork spring are affixed, and the other end of soft band is affixed close to the side of desktop with increasing plate.

Clockwork spring is used so that fixed soft band is scalable on clockwork spring, ensures that gap between plate and desktop will be increased It blocks, when avoiding increasing plate rotation, the hand of user, which stretches into, to be increased between plate and desktop, so as to jam a finger.

Further, first groove and the second groove are T-slot.

Since the first groove and the second groove agree with the top of table leg, so the top of table leg is also T-shaped end, then When table leg moves in the first groove and the second groove, limiting table leg as the first groove of T-slot and the second groove will not It is swung perpendicular to groove, and table leg will not slant and rotate in an axial direction.

Further, the table leg is arranged with rotatable idler wheel with ground contacting part.

It is slided on the ground compared to table leg, when advancing, the idler wheel contacted with ground rolls this programme table leg, reduces table Frictional force between leg and ground improves table leg movement speed, and also reducing electromagnet will drive table leg to move required power Size.

Further, it is equipped with the sliding slot being slidably matched with table leg top in the first groove and the second groove.

Top compared to table leg entire in base case is contacted with desktop, the contact in this programme between table leg and desktop Area reduces, and reduces the frictional force between table leg and desktop so that table leg moves more in the first groove and the second groove It is smooth.

Further, the bottom of the desktop is additionally provided with folding Convenient table.

It is reached along the first groove and the second groove in view of the table leg of desktop and increases the lower part of plate, table is leaned in the support of desktop entirely Coupling part between plate and increasing plate, and coupling part is easily broken off for comparing entire desktop, therefore, in the present solution, increasing Folding Convenient table, table leg move even have arrived at increase below plate when, support entire desktop；So that desk body is more steady Gu；And folding mode, then it is putting and storing for the ease of desk body.
