DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 and Figure 2 As shown, Figure 1 The table frame of the embodiment of the utility model is a perspective view, comprising a table leg 1, a table top, a main frame 21, a connecting frame 22, a lead screw 31, a square nut 32, a movable support 33, a round tube 34, a tilting rod 35 and a support 36. The rear end of the table top is rotatably connected to the main frame 21, a slide groove is provided on the back of the table top, and the main frame 21 is connected to the upper end of the table leg 1;

[0021] The connecting frame 22 is connected to the main support 21, the lead screw 31 is rotatably connected to the connecting frame 22, the axial direction of the lead screw 31 is facing the front-to-back direction, the square nut 32 is sleeved on the lead screw 31, the round tube 34 is rotatably connected to the main support 21, the axial direction of the round tube 34 is facing the left-right direction, the upper end of the movable support 33 is connected to the round tube 34, the lower end of the movable support 33 is connected to the square nut 32, the lower end of the tilting rod 35 is connected to the round tube 34, the upper end of the tilting rod 35 is close to the back of the desktop, the upper end of the tilting rod 35 is connected to the pillar 36, the pillar 36 is slidably connected to the slide groove, and the extension direction of the slide groove is facing the front-to-back direction.

[0022] Specifically, the connecting frame 22 is configured as a cylindrical structure, and two bearings 38 are provided at the front and rear ends, and the front and rear ends of the lead screw 31 pass through the two bearings 38. Secondly, the lead screw 31, the square nut 32, the movable support 33, the round tube 34, the tilt rod 35, the support 36 and the bearing 38 constitute the desktop tilt angle adjustment device.

[0023] In this embodiment, the lead screw 31 is rotated under the support of two bearings 38, and the square nut 32 on the lead screw 31 moves backward with the rotation of the lead screw 31, and at the same time drives the lower end of the movable support 33 connected to the square nut 32 to move backward. Since the upper end of the movable support 33 is connected to the round tube 34, and the two ends of the round tube 34 are located in the round holes on both sides of the main support 21, the round tube 34 rotates in the round holes on both sides of the main support 21 as the lower end of the movable support 33 moves backward. Correspondingly, during the rotation of the round tube 34, the tilting rod 35 connected to the round tube 34 is driven to rotate synchronously, so that the support 36 connected to the upper end of the tilting rod 35 produces relative displacement, thereby driving the support 36 to move in the slide groove on the back of the desktop, pushing the front end of the desktop to gradually tilt up, while the rear end of the desktop remains unchanged, thereby changing the tilt angle of the desktop.

[0024] Therefore, by arranging the lead screw 31 and the square nut 32 in the connecting frame 22, and arranging the movable support 33, the round tube 34, the tilting rod 35 and the pillar 36 between the main bracket 21 and the table top, the devices for adjusting the tilt angle of the table top are all located inside the table frame, which can avoid external structures interfering with the adjustable tilt angle of the table top.

[0025] Alternatively, if Figure 2 As shown, the circular tube 34 is connected to two movable supports 33 , and the two movable supports 33 are respectively located at the left and right ends of the square nut 32 .

[0026] In this embodiment, by providing two movable supports 33 , the round tube 34 can be connected to the square nut 32 at the same time by using the two movable supports 33 , which is beneficial to improving the connection strength between the round tube 34 and the square nut 32 .

[0027] Alternatively, if Figure 2 As shown, the table frame also includes a first crank 37, and the first crank 37 is connected to the front end of the lead screw 31.

[0028] In this embodiment, by setting a first crank 37 on the table frame and connecting the first crank 37 to the front end of the screw 31, the screw 31 can be rotated by rotating the first crank 37, so that the inclination angle of the table top can be adjusted conveniently.

[0029] Alternatively, if Figure 1 As shown, the table frame also includes a side panel 4 , and two table legs 1 are provided. The two table legs 1 are located at the left and right ends of the connecting frame 22 , and the side panel 4 is located at the front side of the two table legs 1 and is connected to the two table legs 1 .

[0030] In this embodiment, by providing the side panels 4, the two table legs 1 can be connected by the side panels 4, and the two table legs 1 can be formed into a whole, which is beneficial to improving the stability of the table frame.

[0031] Alternatively, if Figure 2 and Figure 3 As shown, the table frame also includes a lifting rod 51, a second crank handle 52, a first transmission rod 53, a second transmission rod 54 and a table leg 6. The table leg 1 includes an outer frame and an inner frame. The lower end of the outer frame is connected to the table leg 6, and the inner frame is slidably connected to the outer frame along the vertical direction. The lifting rod 51 is provided in each of the two table legs 1. One end of the lifting rod 51 is connected to the inner frame, and the other end of the lifting rod 51 passes through the inner frame and the outer frame and is connected to the table leg 6. The second crank handle 52 is connected to the main frame 21, and the second crank handle 52 is transmission-connected to one of the lifting rods 51 through the first transmission rod 53; the two lifting rods 51 are transmission-connected through the second transmission rod 54.

[0032] Specifically, the connecting rod is set as a hexagonal rod. The lifting rod 51 includes a gear box, a screw rod and a main structure. The upper end of the screw rod is connected to the gear box, and the lower end is threadedly connected to the main structure. The gear box is connected to the upper end of the inner frame. The screw rod and the main structure are arranged inside the inner frame and the outer frame. The two gear boxes are connected by transmission through the hexagonal rod.

[0033] In this embodiment, by rotating the second crank 52, the right lifting rod 51 can be driven to move in the vertical direction through the first transmission rod 53, thereby driving the inner frame in the right table leg 1 to move in the vertical direction relative to the outer frame. Secondly, the right lifting rod 51 and the left lifting rod 51 are connected in transmission via the second transmission rod 54. When the right lifting rod 51 moves in the vertical direction, the left lifting rod 51 is simultaneously driven to move in the vertical direction, thereby driving the inner frame in the left table leg 1 to move in the vertical direction relative to the outer frame.

[0034] Secondly, by arranging the table foot 6 at the lower end of the outer frame, the stability of the table leg 1 can be improved.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
