Abstract

The utility model provides a movable desk. A lifting rod (6) is fixed under a desktop (1). Two sleeves (16) are fixedly arranged on each of two desk legs respectively in an axial direction, match with the desk legs in a rotary mode, and match with the lifting rod in a screw-thread mode. The two sleeves arranged on the desk legs are worm wheels simultaneously, and are arranged on the same level. A power input shaft is arranged on the desk legs horizontally, which is in a worm gear connection with the sleeves on the desk legs simultaneously. The desk legs are in a reverse T shape, scroll wheels (9) are arranged under the two ends of a cross bar (8), and at least two of the four scroll wheels under the two desk legs are attached with a braking structure. Compared with the prior art, the movable desk has the advantages of few in parts, simple in structure, good in synchronism during operation, low in noise, and effort saving. The scroll wheels under the desk legs enable the desk to be provided with a movable performance relative to the ground, the fact that at least two scroll wheels are provided with a braking structure enables the table to be fixed when movement is not required, therefore the desk can not only be moved, but also be fixed.

Description

Adjustable desk

Technical field

The utility model relates to a kind of adjustable desk.

Background technology

Desk is as one of the main furniture in classroom, bearing and taking in study article and as the effect of learning platform, just be not suitable for the problem that different students height required and moved inconvenience for overcoming desk, produced the desk that roller and elevating mechanism are installed.The desk that elevating function is wherein arranged mainly is to be carried out to go up and down to regulate by the elevating mechanism between desktop and the table pin; As introduce among the Chinese utility model patent ZL200820185045.0 " gear type liftable desk " " comprise 2 table pin and desktop; between table pin and desktop, be provided with lowering or hoisting gear; this lowering or hoisting gear is made up of power input shaft, first bevel gear, second bevel gear, third hand tap gear, elevating lever and sleeve, elevating lever is located in the sleeve elevating lever and is connected with bush whorl, and elevating lever is connected with second bevel gear as the rotating shaft of second bevel gear; second bevel gear respectively with first bevel gear, third hand tap gears engaged; power input shaft is connected with first bevel gear, and said sleeve is connected with a pin, and said elevating lever is connected with desktop." this utility model is through a series of angular wheels the rotation of trunnion axis to be delivered to the rotation of vertical sleeve, makes screw thread and the screw thread in the sleeve on the elevating lever relatively rotate and make desktop to go up and down.Though this structure has realized regulating desktop with the rotation of two sleeves of rotating drive of an axle, numerous bevel gears not only consumes more power, and noise is bigger.

Summary of the invention

To above-mentioned deficiency, the utility model will provide a kind of simple adjustable desk of lifting structure that comprises exactly.

The adjustable desk that the utility model provides has desktop and two table pin, between table pin and the desktop elevating mechanism is arranged, and elevating mechanism comprises power input shaft, elevating lever and sleeve, and elevating lever is fixed under the desktop, and sleeve has that external screw thread cooperates on internal thread and the elevating lever; Wherein quill cooperates to being fixedly mounted on the pin and rotating with the table pin; Said sleeve is worm gear simultaneously; Sleeve on two table pin is installed on the same horizontal plane; The power input shaft level is installed on the pin, and power input shaft simultaneously with two table pin on sleeve be connected as worm and gear; Said table pin is an inverted T-shaped, and below, cross bar two ends, lower end is equipped with roller, and having two rollers in four rollers in two table underfooting at least is rollers of subsidiary brake structure.

The adjustable desk that the utility model provides is connected as worm and gear with the table pin sleeve that cooperates that rotates with two with the transverse axis of a level simultaneously, can drive two sleeves when making the transverse axis rotation and rotate synchronously.Make threaded engagement with elevating lever in the sleeve in addition, the relative sleeve of elevating lever was done to go up and down to change when then sleeve rotated, and was axial restraint between sleeve and the table pin simultaneously, so this up-down shows as the up-down of desktop.Compared with prior art, the utility model part is few, simple in structure, and synchronism is good during operation, noise is low, and laborsaving.And the roller of table underfooting makes desk have the travelling performance on relative ground, but fixed position when at least two roller strap brake structures then make it need not move is not only removable but also can fix.

Also have cabinet, cabinet to be made up of five panel wall except that the place ahead between said desktop and the table pin and be top board with the desktop, the interior dividing plate that is equipped with again forms a plurality of material-putting spaces.Said the place ahead is a side who points to the desk user.

Said desktop forward position is recessed backward camber line shape so that most convenient utilize desk.

The sidewall of said cabinet is equipped with rigidity semi-ring and/or hook outward, and rigidity semi-ring and hook are in order to hanger spare, and the rigidity semi-ring is as carrying handle.

The specific embodiment

One adjustable desk has desktop and table pin, and detailed structure is like Fig. 1,2, shown in 3.Desktop 1 is the top board of a cabinet, and cabinet also has two blocks of side plates 4, a backboard 12 and a base plate 5, is divided into two parts up and down by horizontal baffle in the cabinet.It is bookshelf that the front side, lower part is opened wide, and baseplate width is narrower than top board, its front side is more leaned on than top after, make things convenient for the user to put leg.Top is divided into left and right sides two parts with upright dividing plate again; Wherein drawer 2 of right half placement is used to take in books book or other bigger article; Following three layers of writing case drawer 3 during right half place to be gone up are installed lockset so that take in stationery or article that other are tiny on the drawer.About the table pin divides two, each pin is the T shape support of a handstand, is welded with steel pipe, connects with a steel pipe connecting rod 11 between two table pin.Wherein table pin vertical rod 7 upper ends are spliced dynamic power shaft 13 mount pads backward; And connecting rod two ends and mount pad interior plate are fixed; Power input shaft and connecting rod are through between two table pin coaxially, and at one end pass the mount pad outer panel, and at axle head one up-down handwheel 10 are installed.Power input shaft part in mount pad is a worm screw, has sleeve 16 to cooperate with worm screw with the worm-gear toothing on the lateral surface in the vertical rod of table pin.Sleeve is coaxial with vertical rod, and internal thread is arranged in the sleeve, and other has elevating lever 6 upper ends to be fixed under the cabinet base plate and with external screw thread to cooperate with internal thread of sleeve, and the screw thread rotation direction of the elevating lever in two table pin is identical.Ball grooves is all arranged on the sleeve upper and lower end face, also coaxially in the vertical rod fixed following 18 in the sleeve seat of honour 14 and sleeve, all there is ball grooves the following upper surface of lower surface, the sleeve seat of honour and sleeve, and sleeve is about ball 15 and lower floor's ball 17 are placed in through the upper strata respectively.Like this, when driving power input shaft through handwheel and rotate, connect through worm and gear rotation be delivered to sleeve and since sleeve up and down seat all fix with vertical rod, so the rotation of sleeve makes elevating lever rotate and go up and down relative to sleeve.Table pin cross bar 8 is vertical with connecting rod, promptly is fore-and-aft direction, and a roller 9 respectively is installed under its two ends, and the roller of adorning is the roller of strap brake structure, to make things convenient for the mobile of desk and to locate.Desktop forward position a is recessed backward arc, to alleviate using all compressing of chest.
