Specific embodiments

[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear and understandable, the following further describes the utility model in combination with the accompanying drawings and embodiments.

[0026] Such as Figures 1 to 7As shown in the figure, the present utility model provides a bracket-type desk for expanding the desktop, which includes a desk main body 1 and a desktop adjustment component 2. The desktop adjustment component 2 includes a base bracket 201, a lifting support frame 202, a tabletop panel 203, and an adjustment screw 204. The base bracket 201 is installed on the desk main body 1. The lifting support frame 202 includes a first support frame 2021 and a second support frame 2022 that are cross-hinged. The bottom of the first support frame 2021 is hinged to the base bracket 201, and a first pulley 205 is provided at the top. A first chute 206 for the first pulley 205 to slide is opened at the bottom of the tabletop panel 203. The top of the second support frame 2022 is hinged to the bottom of the tabletop panel 203, and a second pulley 207 is provided at the bottom. A second chute 208 for the second pulley 207 to slide is opened on the base bracket 201. One end of the adjustment screw 204 is installed on the upper part of the second support frame 2022, and the other end is screwed to the upper part of the first support frame 2021. The adjustment screw 204 is parallel to the base bracket 201.

[0027] A stabilizing frame 2016 is fixed to the bottom of the tabletop panel 203. The first chute 206 is provided on the stabilizing frame 2016, and the top of the second support frame 2022 is hinged to the stabilizing frame 2016. The lifting support frame 202, the tabletop panel 203, and the adjustment screw 204 are supported by the base bracket 201 and are arranged on the desk main body 1. The middle parts of the first support frame 2021 and the second support frame 2022 are hinged. Taking the hinge position as the center, the upper part above the hinge position is called the upper part, and the lower part below the hinge position is called the lower part.

[0028] Rotate the adjustment screw 204. Under the rotation of the adjustment screw 204, the distance between the upper parts of the first support frame 2021 and the second support frame 2022 gradually changes. That is to say, the crossing angle between the first support frame 2021 and the second support frame 2022 gradually changes, the distance between the base bracket 201 and the tabletop panel 203 gradually changes, and the height of the tabletop panel 203 relative to the desk main body 1 changes. The user can adjust the height of the tabletop panel 203 by rotating the adjustment screw 204 according to their own needs.

[0029] There are two sets of the base bracket 201 and the lifting support frame 202. A first connecting rod 209 is fixed between the upper parts of the two first support frames 2021, and a second connecting rod 2010 is fixed between the upper parts of the two second support frames 2022. One end of the adjustment screw 204 is installed on the second connecting rod 2010, and the other end is screwed to the first connecting rod 209. The tabletop panel 203 is jointly supported by two sets of the base bracket 201 and the lifting support frame 202, and the lifting is more stable.

[0030] The plane where the first connecting rod 209 and the second connecting rod 2010 are located is parallel to the plane where the tabletop panel 203 is located and parallel to the plane where the two base brackets 201 are located.

[0031] A first mounting seat 2011 is fixed on the first connecting rod 209, a second mounting seat 2012 is fixed on the second connecting rod 2010, one end of the adjusting screw 204 is mounted on the second mounting seat 2012 and is rotatable on the second mounting seat 2012, and the other end of the adjusting screw 204 passes through the first mounting seat 2011 and is threadedly connected to the first mounting seat 2011.

[0032] When the adjusting screw 204 is rotated, the first mounting seat 2011 moves on the adjusting screw 204, the distance between the first mounting seat 2011 and the second mounting seat 2012 changes, so the distance between the first connecting rod 209 and the second connecting rod 2010 also changes, and the overall height of the lifting support frame 202 also changes.

[0033] A rotating handle 2013 is fixed to the end of the other end of the adjusting screw 204.

[0034] A third connecting rod 2014 is fixed between the lower parts of the two first support frames 2021, a gas spring 2015 is fixed on the table main body 1, one end of the gas spring 2015 is fixed on the third connecting rod 2014, and one end of the base support 201 away from the bottom of the first support frame 2021 is hinged on the table main body 1.

[0035] When the adjusting screw 204 stops rotating, the positions of the first support frame 2021 and the second support frame 2022 are fixed, the height of the table top 203 is determined, by adjusting the gas spring 2015, the third connecting rod 2014 is lifted, and the third connecting rod 2014 drives the table top adjusting assembly 2 to start rotating around one end of the base support 201 away from the bottom of the first support frame 2021, and the table top 203 tilts accordingly, which is further convenient for users to work.

[0036] Specifically, a fourth mounting seat 4 is fixed on the table main body 1, a rotating shaft 5 is mounted on the fourth mounting seat 4, and one end of the base support 201 away from the bottom of the first support frame 2021 is fixed on the rotating shaft 5 and rotates on the fourth mounting seat 4 together with the rotating shaft 5.

[0037] A third mounting seat 3 is fixed on the table main body 1, and the bottom of the gas spring 2015 is fixed on the third mounting seat 3. [[ID=..]]

[0038] The table main body 1 includes table legs 101 and a working panel 102, the working panel 102 is supported by the table legs 101, and a receiving groove 6 for receiving the table top adjusting assembly 2 is formed on the surface of the working panel 102. When the table top 203 is lowered to the lowest position, the table top 203 is flush with the working panel 102.

[0039] On both sides of the working panel 102, extension panels 7 are hinged. The extension panels 7 are perpendicular to the working panel 102 in the unloaded state. An active rod 8 is installed on the back of the extension panel 7, and a buckle 9 is provided at the end of the active rod 8. A clamping seat 10 is fixed on the table leg 101. When the buckle 9 is snapped into the clamping seat 10, the extension panel 7 and the working panel 102 are on the same horizontal plane.

[0040] The active rod 8 is hinged on the back of the extension panel 7, and the working panel 102 and the extension panel 7 can be connected by means of hinges or the like.

[0041] When a larger workbench surface is needed, either one of the extension panels 7 is supported or both extension panels 7 are supported simultaneously. The active rod 8 is inclined to support between the extension panel 7 and the table leg 101, and the triangular fixing method ensures the stability of the extension panel 7.

[0042] A long slot 11 for accommodating the active rod 8 is provided on the back of the extension panel 7, and a third sliding slot 12 for the buckle 9 to be snapped into and slide is provided on the table leg 101. The third sliding slot 12 is provided below the clamping seat 10.

[0043] When the extension panel 7 is not needed, the extension panel 7 is allowed to hang down naturally, and the active rod 8 is hidden in the long slot 11, or the buckle 9 is placed in the third sliding slot 12 to make the extension panel 7 slowly hang down. In this way, even if the extension panel 7 is accidentally touched, since the buckle 9 is snapped in the third sliding slot 12, the extension panel 7 will not shake randomly.

[0044] By providing the desktop adjustment assembly 2, the present utility model realizes the height adjustment of the tabletop panel 203; by providing the gas spring 2015, the present utility model realizes the angle adjustment of the tabletop panel 203; by providing the extension panel 7, the available area of the working panel 102 can be flexibly increased or decreased to adapt to different office needs. The present utility model has strong functionality and is more practical.

[0045] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall fall within the protection scope of the present utility model.
