Description

A kind of Liftable type desk

Technical field

The utility model relates to a kind of desks, more particularly, to a kind of lift type desk of table leg adjustable in length.

Background technique

With economic continuous development, people's lives rhythm is gradually accelerated, and all orders of society all exists to the utilization of time The double effects for pursuing improved efficiency and duration accumulation bend over the desk to make what the office workers of office work and students learnt The industry time is increasingly longer.It is exactly desk as the main office furniture utilized of operation of bending over the desk, the desk being widely used at present All be the product that industrialized production comes out, there is fixed structure size design and the scope of application, and different age, gender, The collective effect of congenital heredity factor and acquired disposition etc. cause people stature be it is multifarious, if people used and from The inappropriate desk of oneself stature, will be since the sitting posture being forced is improper, parts of body is in and does not meet ergonomics Posture and in fatigable state is held, long-time service can also cause the chronic diseases problems such as spinal disease, neck omitis disease.In order to Using limitation caused by overcoming fixed-size desk to be applicable in the narrow scope of different people stature, people devise local size The desk that can be adjusted can greatly increase a desk for different bodies particular with the desk of adjustable tabletop height function The scope of application of material crowd.

Notification number is that the Chinese utility model patent of CN201899071U discloses a kind of Liftable type desk, this desk With two length-adjustable table legs, the function of desktop lifting, the people of different statures are realized by adjusting the length of table leg Using the height that can change desktop when this desk according to oneself sitting posture demand and personal preference, it is met not People with stature is able to use with a desk the demand of the suitable height of table top needed for oneself of obtaining, and extends a book Table is applicable in the range of different stature crowds.But this desk needs two table legs to grasp respectively when adjusting table leg length Make, since the self weight of desk tabletop section has constant weight plus frequent bearing article, if it is desired to which two table legs adjust simultaneously Just cooperation must be co-operated from two people to complete, the case where this is for single use desk, or for women, children this For the relatively weak user of class strength, this adjustment mode is all not convenient enough.

Utility model content

In view of this, the purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of lift type desk, especially It is the lift type desk that the length of two sides table leg can adjust simultaneously, it is inconvenient for operation solves single adjustment desk adjustable height The problem of.

In order to achieve the above objectives, the utility model uses following technical scheme:

The Liftable type desk of the utility model is made of desktop, table leg, feet and fastening bolt；The table leg includes It is two identical to be arranged in desktop lower section left and right, is arranged symmetrically by center line of desktop middle, rack gear, table is had on table leg Leg is fastenedly connected with desktop；The structure size of the feet itself using desktop middle as the symmetrical structure of center line, Fluted at position corresponding with table leg rack gear in the feet, locking function can be engaged with rack by being provided in groove The block tongue of energy, the block tongue are hidden in feet groove, are linked between block tongue and feet with spring, and spring is in impaction state, The thrust of spring is intermeshed block tongue with anti-loose with the tooth form on rack gear；The intermediate position of the feet is fixedly installed with one A reel is wound with rope on reel, and rope both ends are connected with two block tongues of the left and right sides, fixed peace on reel Equipped with a pedal, pedal can be rotated freely using the center of reel as axis with fixedly connected be integrated of reel, rotation When reel, the first block tongue and the second block tongue are moved toward one another by the traction of rope simultaneously and are detached from rack gear.On the table leg There is through-hole, the corresponding position in the feet has embedded nut, and the through-hole that the fastening bolt passes through on table leg is tightened in table On embedded nut in foot.

When needing to adjust height of table top, fastening bolt is screwed out to the pre-buried spiral shell for making bolt end exit feet completely first Then mother with the hands holds desktop, then tramples the pedal in the middle part of feet with a foot, make pedal together with reel to tightly wrap rope The direction of rope rotates, and such rope can pull the block tongue of feet two sides to deviate from the rack gear on table leg, and block tongue does not have with rack gear Intermeshing relationship, table leg is just without support force, the both hands for holding desktop at this time are just able to drive desktop and table leg exists It is moved freely in up and down direction in height required for being adjusted to user, foot is then detached from pedal, without quilt on rope The pulling force of reel winding, the block tongue of two sides can be caught in the tooth on table leg under the compressed spring thrust effect connected Item and tooth engagement in the up-down direction fix table leg, and last user, which unclamps, asks the hand of desktop again by table leg two sides Fastening bolt screws in corresponding feet embedded nut, plays the role of further fixing table leg and feet, completes adjustment desktop The operation of height.

Further, fastening bolt selects steel band spring washer bolt, can play the effect reliably fastened.

Further, block tongue selects nylon material, on the basis of guaranteeing hardness, manufacture and mitigation weight easy to process.

The beneficial effects of the utility model are:

The foot-operated strength of human body lower limbs is utilized in the Liftable type desk of the utility model when adjusting height of table top The lockable mechanism between table leg and feet is opened, both hands have thus been liberated, so that both hands is lifted desktop and is moved up and down and is suitble to The height of user realizes the self-return of block tongue using the combination of reel, rope, spring, block tongue, automatically and table Leg rack gear engages the effect for playing table dormant leg length, thereby realizes the function of one man operation's lifting desk height；Due to The foot-operated strength of people is generally greater than arm strength, and set lockable mechanism is opened in the way of foot-operated and is also convenient for women and children The user of equal weaks operates；And the fastening bolt being arranged can increase the reliability that table leg is connect with feet, Desktop, which falls, when preventing block tongue that unexpected disengage is engaged with rack causes the injury of the person and article, plays lockable mechanism insurance Effect ensure that the safety that desk uses.
