Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-4, a desk with adjustable table board angle, including riser 1, backplate 5 and table, the table includes two fixed plates 2 and an regulating plate 4, regulating plate 4 is located between two fixed plates 2, and one end is rotated with fixed plate 2 through the pivot and is connected, the other end is provided with hydraulic stem 3, hydraulic stem 3 and backplate 5 fixed connection, and the end of the piston rod of hydraulic stem 3 articulates there is connecting rod 11, the one end of connecting rod 11 is articulated with regulating plate 4's bottom, the below of table still is provided with hoist mechanism and decline mechanism, be used for going up and down to the piston rod of hydraulic stem 3.
Lifting mechanism includes fixing base 6, footboard 8, plunger 61 and first spring 62, the cavity has been seted up to the inside of fixing base 6, the sealed sliding connection of inner wall of plunger 61 and cavity, sealed department adopts and moves seal structure, for prior art, the one end and the plunger 61 fixed connection of first spring 62, the other end and the inner wall fixed connection of cavity, the one end that first spring 62 was kept away from to plunger 61 extends to the outside of cavity, and offset with the top of footboard 8, footboard 8's bottom is articulated with fixing base 6, inlet tube 10 and the connecting pipe that fixedly connected with and cavity are linked together on fixing base 6, inlet tube 10 and hydraulic stem 3's inside intercommunication, the connecting pipe communicates with descending mechanism.
The pipe orifices of the water inlet pipe 10 and the connecting pipe are respectively provided with a check valve.
Adopt above-mentioned scheme, the check valve adopts single-way rotation's valve clack, the opening direction of valve clack for rivers flow can, for prior art to make water can be by in the pump feed liquor depression bar 3.
Descending mechanism includes water storage tank 9, valve plate 91, footboard 8 and second spring, water storage tank 9 passes through the inside intercommunication of pipeline and hydraulic stem 3, valve plate 91 and the sealed sliding connection of water storage tank 9, be used for carrying out the switch to the pipeline, sealed department adopts and moves seal structure, for prior art, the one end and the second spring fixed connection of valve plate 91, the other end extends to the outside of water storage tank 9, and offsets with the top of footboard 8, footboard 8's bottom is articulated with water storage tank 9, the one end that valve plate 91 was kept away from to the second spring and the inner wall fixed connection of water storage tank 9.
Hydraulic stem 3 and connecting rod 11 all are provided with two, and the symmetry sets up in the bottom of regulating plate 4 respectively, improves the stability of regulating plate 4 when going up and down, connects respectively on two hydraulic stems 3 through two inlet tube 10 on fixing base 6 this moment to ensure that two hydraulic stems 3 go up and down in step.
The back plate 5 is fixedly connected with a cover 7, and the cover 7 covers the hydraulic rod 3, so that the hydraulic rod 3 is hidden, and the attractiveness and the cleanliness of the desk are improved.
The bottoms of the lifting mechanism and the descending mechanism are fixedly connected with non-slip mats, so that the non-slip mats can be prevented from sliding when the pedals 8 are trampled.
The lifting mechanism and the descending mechanism are both fixedly connected with the back plate 5, so that the pedal 8 is prevented from sliding when being stepped.
The working principle is as follows: when in use, a user steps on the pedal 8 on the fixed seat 6 with a foot, the pedal 8 props against and drives the plunger 61 to slide on the inner wall of the fixed seat 6, and is restored under the action of the first spring 62, so that the plunger 61 continuously slides on the fixed seat 6 while the user continuously steps on the pedal, so that the water in the water storage tank 9 is continuously pumped into the hydraulic rod 3 to push the piston rod of the hydraulic rod 3 to rise, and one end of the adjusting plate 4 is driven to rise, so that the adjusting plate 4 is inclined, when the adjusting plate 4 needs to be restored, a user only needs to step on the pedal 8 on the water storage tank 9 by feet, the pedal 8 supports against and drives the valve plate 91 to move on the water storage tank 9, so that the inside of the water storage tank 9 is communicated with the hydraulic rod 3, at the moment, the water in the hydraulic rod 3 flows into the water storage tank 9, the piston rod of the hydraulic rod 3 slowly descends under the action of gravity, and finally the adjusting plate 4 is driven to be in a horizontal state.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
