Description

Table angle adjustment device

Technical field

The utility model is related with desk, particularly relates to a kind of easily operated and good stability table angle adjustment dress It sets.

Background technique

In order to cooperate the user of different statures, other than adjustable tabletop height, the desktop of general desk is mostly Had the design of adjustable tabletop angles, user is allowed desktop first can be adjusted to optimum position before the use, to keep away Exempt from that the bad problem of posture occurs.

For the convenience adjusted, one end of air pressure rod is mainly articulated in the bottom surface of desktop in traditional design, led to Cross air pressure rod it is flexible come achieve the effect that adjust tabletop angles, but so structure configuration will lead to air pressure rod need it is longer Actuating length, too long actuating length is easy to allow the bad stability of desktop, thus has improved necessity.

Summary of the invention

In view of the above-mentioned problems, the main purpose of the utility model is to provide a kind of table angle adjustment device, operation Convenient and stability is good.

In order to achieve the above objectives, a kind of table angle adjustment device provided by the utility model, it is characterised in that include Have: a bracket has an antero-lateral rod；One desktop, the bottom surface of the desktop are hubbed at the antero-lateral rod of the bracket；One adjustment is single Member has a connecting rod, a driving source and a trigger switch, and the front end of the connecting rod is hubbed at the antero-lateral rod of the bracket, described Driving source has a cylinder body and a piston rod, and the cylinder body can axially be set to the bottom surface of the desktop along itself, and The front end of the cylinder body is hubbed at the rear end of the connecting rod, and the piston rod can axially be set to the cylinder body and have one Make moved end, the bottom surface for making moved end and being located at outside the cylinder body and being fixedly arranged on the desktop, the trigger switch is set to the table The bottom surface of the plate and piston rod for corresponding to the driving source makees moved end, so that the trigger switch can be by external force ejection institute That states piston rod starts the driving source as moved end.

In above-mentioned the technical solution of the utility model, a first axle is utilized between the connecting rod and the cylinder body of the driving source Part is pivoted together, and one end of first shaft member is equipped with an idler wheel, and the idler wheel is connected to the bottom surface of the desktop.It can increase Add smooth degree and stability of the cylinder body in action process.

The bottom surface of the desktop is equipped with a stiffening plate, and the stiffening plate abuts the idler wheel.To prevent the idler wheel dynamic The bottom surface of the desktop is caused to wear during work.

The cylinder body of the driving source can axially be arranged in a cylinder body fixing seat, the cylinder body fixing seat along itself Set on the bottom surface of the desktop.

The trigger switch is hubbed at a switch base using one second shaft member, and the switch base is set to the bottom surface of the desktop And with the piston rod to make moved end affixed.

By adopting the above technical scheme, when using trigger switch starting driving source, since the moved end of making of piston rod is kept not It is dynamic, so cylinder body meeting opposing pistons bar is moved along, connecting rod can be promoted up to be lifted during cylinder body is moved along, and same When ejection desktop bottom surface, so that desktop is gradually become heeling condition from the horizontality of script, until adjust angle appropriate it Afterwards, trigger switch can be decontroled to close driving source, be held in position desktop.

Specific embodiment

In order to which the structure, feature and effect of the utility model is described in detail, now lifts preferred embodiments below and cooperate attached drawing It is described as follows.

Applicant illustrates herein first, in the following embodiment and schema that will be introduced, identical reference number, and table Show same or similar element or its structure feature.

Please referring initially to Fig. 1 to Fig. 3, shown in figure is that the table angle adjustment device 12 of the utility model is propped up with a pair Desk 10 made of foot 14 is arranged in pairs or groups.The table angle adjustment device 12 of the utility model includes a bracket 20, a desktop 30 and an adjustment unit 40.

Bracket 20 has a left side bar 21, a right-hand rod 22 and an antero-lateral rod 23, and left and right side lever 22 therein is solid respectively It is connected to the top of a stabilizer blade 14, the front end of left and right side lever 21,22 is integrally attached to as antero-lateral rod 23.

The bottom surface of desktop 30 is hubbed at the antero-lateral rod 23 of bracket 20, so that desktop 30 can be acted with respect to bracket 20.

As shown in Figures 3 and 4, adjustment unit 40 has a connecting rod 41, a driving source 42 and a trigger switch 49, in which: The front end of connecting rod 41 is hubbed at the antero-lateral rod 23 of bracket 20；Driving source 42 (being in the present embodiment pneumatic cylinder) has a cylinder body 43 With a piston rod 44, cylinder body 43 therein can axially be arranged in a cylinder body fixing seat 45, cylinder body fixing seat along itself 45 are locked on the bottom surface of desktop 30 using the fixing element of such as screw etc, and the front end of cylinder body 43 utilizes one first shaft member P1 It is hubbed at the rear end of connecting rod 41, the both ends of the first shaft member P1 are separately installed with an idler wheel 46, and second wheel 46 is connected to by metal material A stiffening plate 47 made by matter, stiffening plate 47 is locked on the bottom surface of desktop 30 using the fixing element of screw etc, as work Stopper rod 44 can axially be set to cylinder body 43 and have one to make moved end 442, and the moved end 442 of making of piston rod 44 is located at outside cylinder body 43 And it is fixedly arranged on a switch base 48 using the fixing element of nut etc, switch base 48 is locked using the fixing element of such as screw etc Set on the bottom surface of desktop 30；Trigger switch 49 using one second shaft member P2 be pivoted switch base 48 and correspond to driving source 42 piston Bar 44 makees moved end 442.

When the angle of desktop to be adjusted, trigger switch 49 is up pulled with hand, makes 49 ejector ram bar 44 of trigger switch Make moved end 442 to start driving source 42, at this time because piston rod 44 makees that moved end 442 is fixed, and cylinder body 43 can phase It is mobile towards the direction far from trigger switch 49 to piston rod 44, it as shown in Figures 4 and 5, can band during cylinder body 43 is mobile Dynamic connecting rod 41 is up lifted, and second wheel 46 is made to be connected to the surface of stiffening plate 47, and then second wheel 46 can holding with cylinder body 43 Continue movement along the surface scrolls of stiffening plate 47 and by the bottom surface of 47 ejection desktop 30 of stiffening plate, makes desktop 30 from script Horizontality gradually becomes heeling condition, when desktop 30 is adjusted to angle appropriate, can decontrol trigger switch 49 Driving source 42 is closed, desktop 30 is held in position, so completes the adjustment of tabletop angles.

In conclusion the table height adjustment device 10 of the utility model by driving source 42 be arranged in desktop 30 bottom surface and Driving source 42 is arranged in an inverse manner, can so shorten the actuating length of driving source 42 when adjusting tabletop angles, make table Plate 30 is able to maintain good structural stability when heeling condition is presented.In addition, the height of table top of the utility model adjusts dress Smooth degree and stability of the cylinder body 43 in action process can be increased by the setting of second wheel 46 by setting 10, additionally by reinforcement The setting of plate 47 can prevent second wheel 46 from causing the abrasion in structure to the bottom surface of desktop 30, to prolong the service life.
