Detailed description of the invention
Please refer to Fig. 1 to Figure 16, a kind of desk, comprise the mechanism C of a support leg mechanism A, a desktop assembly B and a specification read-write posture.
This support leg mechanism A, comprises base 10, telescoping tube mechanism 12 and a pallet 14, and this telescoping tube mechanism comprises pipe 16 and can slide up and down the upper pipe 18 being connected lower pipe 16, the affixed base 10 of this lower pipe 16, the affixed pallet 14 of pipe 18 on this.This desktop assembly B, mounting or dismounting maybe can not can be fixed in support leg mechanism A top with installing and removing, this desktop assembly B comprises chassis 26, desktop 28 and recliner adjuster 30, on front side of this desktop 28 on front side of pivot joint chassis 26, this recliner adjuster 30 connects desktop 28 and chassis 26, and this chassis 26 is fixed in support leg mechanism A top.
In this support leg mechanism A mono-concrete structure:
Please refer to Fig. 1 and Figure 16, base 10 is the I-shaped underframe of steel construction.Have a square opening above this I-shaped underframe middle, for inserting and fixing down pipe 16, bottom I-shaped underframe, a circular hole has been got in middle, for through pipe 16 under screw lock.I-shaped underframe four angles have four to land adjustment pin, regulate below the chassis of pin and are stained with rubber packing, and rubber packing can make the contact on itself and ground better.The each self energy of each adjustment pin regulates height.
Please refer to Fig. 1, Fig. 3 and Fig. 5, telescoping tube mechanism 12 adopts steel construction, and upper pipe box is in lower pipe, and lower pipe 16 and upper pipe 18 can slide to regulate height mutually.This lower pipe is provided with anti-drop device, crosses and draws to limit upper pipe and depart from lower pipe.This lower pipe is provided with fixed mechanism for regulating the rear level altitude of highly locking after degree of tightness, such as comprise a fixed knob, this fixed knob is threaded through lower pipe, this spiral end end contact, at lower pipe lateral surface, locates the relative position of lower pipe and upper pipe by the frictional force between end and lower pipe lateral surface.Best, built-in gravitational equilibrium spring (for balancing the gravity of desktop assembly) and noise reduction lining (sound produced during for eliminating lifting) between top tube and down tube.
Or as required, fixed mechanism 17 such as comprises support 171, pinch roller, wheel pressing shaft and action bars 172; Support 171 is fixed in outside lower pipe 16, and pinch roller can be rotationally connected support 171 by wheel pressing shaft, the part that lower pipe 16 runs through inside and outside establishing, and the part of pinch roller puts in the part that runs through can contact the upper pipe lateral surface being positioned at lower pipe; The affixed pinch roller of action bars 172 rotates can drive pinch roller.Pinch roller cylindrical is positive round, and center is eccentric shaft, and eccentric amplitude wants appropriateness.As required, also comprise compression spring, action bars, outer cover, wheel pressing shaft still grows 1.2 centimetres after being inserted in support, the part grown is for putting rotational pressure spring, one of spring is fixed on support, one is fixed on wheel pressing shaft, and action bars one has screw thread for pinch roller and wheel pressing shaft being interfixed.When action bars drives pinch roller toward (toward arsis) during the direction motion launched, the distance of wheel pressing shaft and pinch roller cylindrical strengthens, now the cylindrical of pinch roller contacts with upper pipe and presses tighter and tighter until cannot continue to move and block, and is pressed tightly within the outer tube by upper pipe and fixes.Now rotational pressure spring still remains the pressure to pinch roller expansion direction, thus secure height, if action bars down one claps pinch roller gently, during toward the direction motion of interior contraction, pinch roller departs from and the contact of inner sleeve and without pressure, now the inside and outside sleeve pipe of elevating lever can unclamp free activity.Fixed mechanism is the principle work utilizing spiral evolute, due to pinch roller to the active force of upper pipe in theory on one wire, when action bars is just more laborsaving and easy by lever force operation, and up and down pipe contact theory is a plane, under the pressure effect of pinch roller, very large frictional force will be produced between pipe up and down and not easily move, and press tighter and tighter until block, play fixation, this fixed mechanism pinch roller outside diameter 40mm axial length 40mm takes turns shaft diameter 16mm, detect through reality, when depending merely on after fixed mechanism fixes, place the weight of 150 kilograms on the table, the position of elevating lever at all constant (not carrying out more than 150 kilograms and destructive testing), the larger holding capacity of workpiece size of fixed mechanism is larger, if there is special requirement, upper and lower Guan Ke is made into the pentagonal (direction on pinch roller active force opposite, up and down pipe while by while change outwardly both sides into, other three limit of pipe is constant), fixed effect is just superior especially.The feature of this fixed mechanism is: make simple and easy, easy to operate, can be widely used in the height that is similar to the objects such as tables and chairs and position need variation after fixing, current market is the device that is fixed of this principle useless still.
Please refer to Fig. 1, Fig. 7, Fig. 9 and Figure 11, this pallet 14 adopts steel construction, and pallet is for placing desktop assembly, pallet there are four alignment pins 20, four locating holes are established on chassis 26, and pin-and-hole coordinates to locate desktop assembly B exactly, and prevents their relative levels from moving.There is a square tube pallet 14 middle, and square tube wall has respectively got a hole, and the inside dimension of square tube pipe just in time can be allowed to insert and uses four screws to fix.The right and left of this pallet 14 is respectively provided with a combination and buckles 22, and this combination button 22 can rotate freely by opposing tray 14, and combination button 22 is provided with hook groove; Chassis 26 the right and left of desktop assembly establishes pin buckle 24, and this groove and pin buckle 24 coordinate, and combines button 22 for fastening or decontrol the pin buckle of desktop chassis the right and left, to reach the effect fastening or decontrol desktop assembly.
In this desktop assembly B mono-concrete structure:
Please refer to Fig. 1 and Figure 10, the chassis 26 of this desktop assembly is fixed on pallet 14.This desktop 28 is made up of along (anti-desktop stationery downslide) lightweight wood desktop and gear; This chassis 26 adopts timber structure.Be connected by hinge flap on front side of this chassis with on front side of desktop.This chassis is used for fixing " recliner adjuster ", " buffer ", " minimum gradient pad ", also can put and coordinate drawer 27, for the little stationery of placement.Best, be pasted with very thin one deck skid resistant course below chassis and have four locating holes.
Please refer to Fig. 8; this buffer comprises friction plate 32 and Connection Block 34; this friction plate 32 is fixed in desktop 28 bottom surface; this Connection Block 34 is fixed in chassis 26 end face; this Connection Block 34 be connected with one can be movable bullet 36 and the elastomer of a contact between bullet 36 and Connection Block 34 and for bearing cushioning effect, this friction plate 32 and bullet 36 match.This bullet 36 can be slidably connected Connection Block 34 on ground, opposing parallel chassis 26, and this friction plate 32 vertical table surface plate 28 bottom surface and friction plate 32 end are set to the guide section 38 towards being obliquely installed away from bullet 36 direction, and this guide section 38 and bullet 36 contact coordinate.When adjusting method fault or the error of desktop 28 gradient, desktop 28 can decline fast, can play good buffering Noise Reduction when dropping to friction plate 32 and contacting with bullet 36.
