Abstract
The utility model discloses folding tables on a kind of single arm type bed, including pedestal, support rod, adjustment bar and desktop, the pedestal is equipped with fixed screw, and the pedestal is fixedly connected with support rod, is connected by gear type shaft between the support rod and adjustment bar, between adjustment bar and desktop.The gear type shaft of the utility model keeps overall structure more stable, pressure-resistant, and the angle and height of desktop can be adjusted arbitrarily, easy to use.Folding back support rod, adjustment bar, desktop three can keep 0 degree of angle, occupy little space, at the same folded desktop still can rotate to horizontal direction continue store article, avoid desktop be in bed top caused by body collide with, compact overall structure reduces interior space occupancy.
Description
Technical field
The utility model relates to a kind of desks, and in particular to folding table on a kind of single arm type bed.
Background technique
Currently, most of students' dormitory is not equipped with desk since space is limited, this to many classmates read a book study or
Cause many inconvenience when person is using computer, greatly reduce learning efficiency, although and traditional foldable table on bed in certain journey
Such case is improved on degree, still, is put in bed when using every time, and height cannot be adjusted, and largely limit body
The freedom of body, bed will also be taken down by having used, and excessively heavy, occupied space is also big, and especially the classmate to upper berth brings many troubles.
Through retrieving, Chinese Patent Application No. 201120100179.X, the applying date is the utility model list of 2011.03.31
Arm supported multifunctional small desk, the utility model teapoy can be folded, in addition the adjustable desktop upper-lower height of telescopic rod,
Compound rod can be such that desktop is rotated, and teapoy is fixed on bed by fixed device.Its shortcoming is that the movable joint used is set
Count it is unstable, bear weight after movable joint easily rotate, the support strength of desk is poor.The rotation mode of desktop is cumbersome, folds
Scaling operation is complicated.In addition, compound rod and telescopic rod folding cannot reach 0 degree of angle, occupied space is still larger.
Summary of the invention
To solve the above problems, the utility model provides folding table on a kind of single arm type bed, connected using gear type shaft
Each component, supporting & stablizing, folding back support rod, adjustment bar, desktop three can keep 0 degree of angle, occupy little space, have using letter
The advantages of folk prescription just, can arbitrarily adjust height of table top angle, supporting & stablizing, flexible operation.
To achieve the goals above, the technical scheme is that folding table on a kind of single arm type bed, it is characterised in that:
Including pedestal, support rod, adjustment bar and desktop, the pedestal is equipped with fixed screw, and the pedestal is fixedly connected with support rod,
By being connected between the connection of gear type shaft I, adjustment bar and desktop by gear type shaft II between the support rod and adjustment bar
It connects, the gear type shaft I is identical as II structure of gear type shaft；
The gear type shaft includes spring, inner shaft and positioning hollow posts, and the inner shaft passes through positioning hollow posts, described fixed
Position hollow posts include the first hollow plate sequentially coaxially connected, the second hollow posts, external gear and third hollow posts, in described first
Hollow plate internal diameter is identical as the hollow column internal diameter of third and matches with interior shaft diameter, and the inner shaft is equipped with internal gear, the internal tooth
Wheel engage with external gear, and the second hollow column internal diameter is greater than internal gear outer diameter, the first hollow plate of spring one end connection, separately
One end connects internal gear；
The gear type shaft I positions hollow posts connection support bar, and axis connection adjusts bar one in the gear type shaft I
End, the gear type shaft II position hollow posts and connect with the adjustment bar other end, axis connection desktop in the gear type shaft II.
Beneficial effects of the present invention:
1, the utility model is fixed on bedstead by pedestal, can be realized Quick extension and folding, is eliminated and is removed back and forth
The inconvenience of fortune.
2, the gear type shaft of the utility model keeps overall structure more stable, pressure-resistant, and the angle and height of desktop can appoint
Meaning adjustment, it is easy to use.
3, folding back support rod, adjustment bar, desktop three can keep 0 degree of angle, occupy little space, while folded desktop
Still can rotate to horizontal direction continue store article, avoid desktop be in bed top caused by body collide with, overall structure is tight
It gathers, reduces interior space occupancy.

Specific embodiment
Embodiment 1
As shown in Figures 1 to 6, folding table on a kind of single arm type bed, it is characterised in that: including pedestal 2, support rod 3, adjustment
Bar 5 and desktop 6, the pedestal 2 are equipped with fixed screw 1, and the pedestal 2 is fixedly connected with support rod 3, the support rod 3 and
It adjusts between bar 5 by passing through the II 4b connection of gear type shaft, institute between the I 4a connection of gear type shaft, adjustment bar 5 and desktop 6
It is identical as II 4b structure of gear type shaft to state I 4a of gear type shaft；
I 4a of gear type shaft, II 4b of gear type shaft include spring 47, inner shaft 41 and position hollow posts, described
Inner shaft 41 passes through positioning hollow posts, and the positioning hollow posts include the first hollow plate 43, the second hollow posts sequentially coaxially connected
44, external gear 45 and third hollow posts 46,43 internal diameter of the first hollow plate is identical as 46 internal diameter of third hollow posts and and inner shaft
41 diameters match, and the inner shaft 41 is equipped with internal gear 42, and the internal gear 42 is engaged with external gear 45, and described second is hollow
44 internal diameter of column is greater than 42 outer diameter of internal gear, and described 47 one end of spring connects the first hollow plate 43, the other end connects internal gear 42；
I 4a of gear type shaft positions hollow posts connection support bar 3, axis connection adjustment in I 4a of gear type shaft
5 one end of bar, II 4b of the gear type shaft positioning hollow posts are connect with adjustment 5 other end of bar, in II 4b of gear type shaft
