Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

A desk with an adjustable desktop angle is shown in a figure 1-2 and comprises supporting legs 1, desk plates 2, a desktop 3, baffles 4, racks 5, supporting rods 6, rotating shafts 7, transmission gears 8, transmission devices 9, rocking handles 10 and limiting devices 11, wherein the desk plates 2 are fixedly arranged on the supporting legs 1, the desktop 3 is arranged between the desk plates 2 on two sides, a rotating shaft is arranged at the front end of the desktop 3, two ends of the rotating shaft are hinged with two sides of the desk plates 2, the baffles 4 are connected between the desk plates 2 on two sides of the rear end of the desktop 3 in a sliding mode, the baffles 4 are in contact with the desktop 3, the supporting legs 1, the desk plates 2, the desktop 3 and the baffles 4 form a desk cavity, the racks 5 are fixedly arranged in the middle of the inner sides of the baffles 4, the supporting rods 6 are fixedly arranged on the rear sides of the tops of the supporting legs 1, the supporting rods 6 are positioned on one sides of the racks 5, through holes are formed, the transmission gear 8 is meshed with the rack 5, a transmission device 9 is arranged inside one side of the table plate 2, the other end of the rotating shaft 7 is connected with the transmission device 9, a rocking handle 10 is arranged on the outer side of the table plate 2, and a limiting device 11 is arranged around the rocking handle 10.

The connecting pieces of the table plates 2 at the two sides and the baffle 4 can be in sliding connection by drawer sliding rails.

When the operator needs to mediate 3 angles on the desktop, only need rotate rocking handle 10, because rocking handle 10 is connected with drive gear 8 through transmission 9, so when rocking handle 10 rotated, drive gear 8 on the rack 5 also can rotate to drive baffle 4 through rack 5 and upwards remove, because rack 5 one side is kept away from to desktop 3 is equipped with the axis of rotation, so can make desktop 3 be close to rack 5 one side and upwards lift, thereby accomplish the adjustment to 3 angles on the desktop.

As shown in fig. 3, the transmission device 9 includes a transmission case 901, a small gear 902 and a large gear 903, the transmission case 901 is fixedly installed inside one side of the table board 2, the small gear 902 is installed in the middle of the transmission case 901, the rocking handle 10 is connected with the small gear 902, the large gear 903 is installed on one side of the small gear 902, the large gear 903 is connected with the rotating shaft 7, and the large gear 903 is engaged with the small gear 902.

When the rocking handle 10 is rotated, the rotating shaft 7 of the rocking handle 10 drives the pinion 902 in the transmission box 901 to rotate, so as to drive the gearwheel 903 contacted with the pinion 902 to rotate, and the gearwheel 903 and the transmission gear 8 are positioned on the same rotating shaft 7, so that the transmission gear 8 also rotates along with the gearwheel 903, thereby realizing the transmission function.

Example 2

On the basis of embodiment 1, as shown in fig. 4, the limiting device 11 includes a fixing seat 111, a rotating column 112 and a limiting plate 113, six fixing seats 111 are uniformly installed around the rocking handle 10 at intervals, the rotating column 112 is rotatably connected to the fixing seat 111, and the limiting plate 113 is installed on the rotating column 112 towards the direction of the rocking handle 10.

After the angular adjustment of desktop 3 finishes, limiting plate 113 on fixing base 111 can rotate from top to bottom through rotating post 112, when limiting plate 113 adjusts the suitable position, can play limiting displacement to rocking handle 10 to make rocking handle 10 can not rotate at will, realized the function of fixed desktop angle.

As shown in fig. 4, the limiting device 11 further includes a clamping spring 13 and a clamping ball 14, a sliding groove 12 is formed in the middle of the inside of the fixed seat 111, the clamping spring 13 is installed in the sliding groove 12, the clamping ball 14 is installed at the top end of the fixed seat 111, two ends of the clamping spring 13 are respectively connected with the bottom of the sliding groove 12 and the clamping ball 14, and four clamping grooves 15 are formed in the middle of the periphery of the rotating column 112.
