Description
Technical field
The utility model relates to a kind of desk, particularly relates to a kind of high guidance quality anti-rotation table, is mainly used in the field such as desk, medical dinning table.
Background technology
Two kinds of modes are had: a kind of is adopt air spring to coordinate locking mechanism to realize, and will be fixed by external force after tables and chairs push-and-pull to certain altitude with locking mechanism again the up-down mode of common at present desk (as negotiation table etc.), sick bed dining table etc.; Another kind is that air spring coordinates sawtooth device, and the position that this up-down mode can only pre-set at sawtooth device is elevated.Above-mentioned two kinds of modes have certain limitation; and usually can find in the process to use in reality tables and chairs fixing be not very firm, often occur rocking, and easily occur the phenomenons such as stuck in lifting process; guide effect is poor, brings a lot of inconvenience to user.
Utility model content
Technical problem to be solved in the utility model provides a kind of high guidance quality anti-rotation table for above-mentioned prior art, while raising lifting effect, can guarantee not rotate and stuck phenomenon, improve the smooth and easy and stability of lifting, be user-friendly to.
The technical scheme in the invention for solving the above technical problem is: a kind of high guidance quality anti-rotation table, at the bottom of comprising, elevating mechanism and desktop, elevating mechanism comprises base, be installed with fairlead on the base, described fairlead inside is provided with the lockable gas spring providing lifting drive, the bottom of this lockable gas spring is fixedly connected with base, lifting guide pillar is provided with between described fairlead and lockable gas spring, described lifting guide pillar is with on lockable gas spring, lower motion, the wall of fairlead is symmetrically arranged with and organizes the deflector roll contacted with the outside wall surface of lifting guide pillar more, and deflector roll and lifting guide pillar are mutually vertical, the valve of described lockable gas spring is provided with a rotor plate, described rotor plate is connected with the starting switch be arranged on below desktop by a pull lever.
Described fairlead and lifting guide pillar are regular hexagon structure, and deflector roll interval is installed on the wall of fairlead.
Have hidden for the deflector roll shell in inside in described fairlead arranged outside.
Compared with prior art, the utility model has the advantage of:
The utility model is contacted with lifting guide pillar by deflector roll, change sliding friction in the past into rolling friction, thus improve the smooth and easy effect of desk lifting, simultaneously the fairlead of hexagonal structure and lifting guide pillar structure can prevent to rotate, and the stability of elevating mechanism is more increased.
Accompanying drawing explanation
Fig. 1 is the structural representation in the utility model embodiment.
Fig. 2 is the elevating mechanism structural representation in the utility model embodiment.
Fig. 3 is the transverse sectional view of Fig. 2.
Wherein:
The table end 1, elevating mechanism 2, desktop 3, base 2.1, fairlead 2.2, lockable gas spring 2.3, supporting plate 2.4, lifting guide pillar 2.5, deflector roll 2.6, shell 2.7, rotor plate 4, pull lever 5, starting switch 6.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, one in the present embodiment high guidance quality anti-rotation desk, at the bottom of comprising 1, elevating mechanism 2 and desktop 3, the two ends of elevating mechanism 21 to be connected with desktop 3 with at the bottom of table respectively, described elevating mechanism 2 comprises base 2.1, for 1 being connected with at the bottom of table, this base 2.1 is installed with fairlead 2.2, described fairlead 2.2 inside is provided with the lockable gas spring 2.3 providing lifting drive, the bottom of this lockable gas spring 2.3 is fixedly connected with base 2.1, top is connected with a supporting plate 2.4 being used for supporting desktop 3, lifting guide pillar 2.5 is provided with between described fairlead 2.2 and lockable gas spring 2.3, top and the supporting plate 2.4 of described lifting guide pillar 2.5 are fixed, bottom is unsettled can move at fairlead 2.2 internal freedom, lifting guide pillar 2.5 is driven to move up and down by the effect of lockable gas spring 2.3, thus make supporting plate 2.4 drive the desktop fixing with it to realize being elevated, because the contact between lifting guide pillar 2.5 and fairlead 2.2 exists sliding friction, in order to reduce frictional force, improve lifting smoothly, the wall of fairlead 2.2 is symmetrically arranged with many group deflector rolls 2.6, deflector roll 2.6 is bolted, and deflector roll 2.6 is mutually vertical with lifting guide pillar 2.5, such lifting guide pillar 2.5 contacts with each other with deflector roll 2.6, sliding friction is become rolling friction, reduce the resistance in lifting process, improve lifting effect.The valve of described lockable gas spring 2.3 is provided with a rotor plate 4, described rotor plate 4 is connected with the starting switch 6 be arranged on below desktop 3 by a pull lever 5, user presses starting switch 6, drive rotor plate 4 by valve open by pull lever 5, under the effect of lockable gas spring 2.3, realize the lifting of desk.
On the other hand, the stability of desk, chair etc. is affected in order to prevent from occurring between lifting guide pillar 2.5 and fairlead 2.2 rotating, fairlead 2.2 and lifting guide pillar 2.5 are designed to regular hexagon structure (as shown in Figure 3), deflector roll 2.6 interval is installed on the wall of fairlead 2.2, namely the deflector roll 2.6 contacted with lifting guide pillar 2.5 being installed on three walls of fairlead 2.2, just can realizing being elevated the smooth and easy effect with preventing from rotating.
In order to the aesthetic of whole device, have hidden for deflector roll 2.6 shell 2.7 in inside in described fairlead 2.2 arranged outside.
In addition to the implementation, the utility model also includes other embodiments, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection domain that all should fall into the utility model claim.
