Detailed Description

The present application is described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses desk with adjustable height, refers to fig. 1 and 2, including desktop 1, the both ends of terminal surface have set firmly table leg 2 along vertical direction under the desktop 1, and table leg 2 is outer to be equipped with supporting leg 3 along the coaxial cover of vertical direction. When the office table works, the table top 1 is in the horizontal position to support office supplies of a user at a required position, the supporting legs 3 are abutted against the ground to support the table legs 2, and the table legs 2 support the table top 1 at the horizontal position, so that the basic use function of the office table is realized.

Referring to fig. 1 and 2, the two sides of the bottom end of the supporting leg 3 are fixedly provided with a supporting seat 13 perpendicular to the supporting leg 3, and the supporting seat 13 is arranged along the width direction of the table top 1. When using the desk, supporting seat 13 and ground looks butt, supporting leg 3 cooperatees with supporting seat 13 and increases and the area of contact between the ground, and supporting seat 13 supports supporting leg 3 on required position more steadily, and then makes desktop 1 difficult and ground emergence in the use rock.

Referring to fig. 1 and 2, the support leg 3 is slidably connected to the table leg 2 in a vertical direction coaxially. When the user need change the height of desktop 1, the user moves table leg 2 along vertical direction, makes 2 lifting movement of table leg, table leg 2 and supporting leg 3 relative slip this moment, because supporting leg 3 is static relatively with ground, consequently when table leg 2 and supporting leg 3 along vertical direction sliding connection, table leg 2 drives desktop 1 and arranges vertical direction in and removes, and then makes the change of the terrain clearance of desktop 1, realizes 1 regulatory function of desktop of desk.

Referring to fig. 1 and 2, a sliding groove 10 is provided along the vertical direction on both sides of the outer wall of the table leg 2, and sliding blocks 11 slidably connected with the sliding groove 10 along the vertical direction are fixedly provided along the length direction of the table top 1 on both sides of the upper end surface of the supporting leg 3. When a user needs to adjust the height of the desktop 1, the desk legs 2 and the supporting legs 3 slide relatively along the vertical direction, at the moment, the sliding blocks 11 are arranged in the sliding grooves 10 to slide along the vertical direction, and the sliding grooves 10 enable the relative sliding process between the desk legs 2 and the supporting legs 3 to be more stable through limiting the moving track of the sliding blocks 11.

Referring to fig. 1 and 2, a lifting screw 4 is rotatably connected to the support table in a vertical direction and is rotated in an axial direction thereof, and an upper end of the lifting screw 4 is disposed in a lower end of the table leg 2 and is coaxially screw-connected to the table leg 2. When a user needs to adjust the height of the desktop 1, the user rotates the lifting screw rod 4 to enable the upper end portion of the lifting screw rod 4 to be arranged in the lower end portion of the desk leg 2 to rotate, then the desk leg 2 is enabled to move in the vertical direction in the process of being in threaded connection with the lifting screw rod 4, then the height of the desk leg 2 is changed, the desk leg 2 drives the desktop 1 to move in the vertical direction, and the height adjusting function of the office desk is achieved.

Referring to fig. 1 and 2, lifting bevel gear 5 has set firmly along the horizontal direction is coaxial in the bottom of lifting screw 4, and the bottom of supporting leg 3 rotates along vertical direction to be connected with along its axis direction pivoted rotation bevel gear 6, and rotation bevel gear 6 is connected with lifting bevel gear 5 meshing. When a user needs to adjust the height of the desktop 1, the user rotates the rotating bevel gear 6, the rotating bevel gear 6 rotates to enable the lifting bevel gear 5 to rotate so as to drive the lifting screw rod 4 to rotate along the axis direction of the lifting bevel gear, and the lifting screw rod 4 further drives the desk legs 2 to move in the vertical direction, so that the lifting process of the desk legs 2 is more stable.

Referring to fig. 1 and 2, a synchronizing rod 9 is rotatably connected between the supporting legs 3 along the length direction of the table top 1, the end faces of the two rotating bevel gears 6 are arranged oppositely, the two ends of the synchronizing rod 9 penetrate through the side walls, close to each other, of the two supporting legs 3 respectively, and the two ends of the synchronizing rod 9 are coaxially and fixedly connected with the circle center positions of the two rotating bevel gears 6. When the user need adjust the height of desktop 1, synchronizing bar 9 couples together two and rotates bevel gear 6 fixed connection, and when the user rotated one and rotates bevel gear 6, synchronizing bar 9 followed this and rotated bevel gear 6 and rotated, and then drove another and rotated bevel gear 6 and rotate, and synchronizing bar 9 made two and rotated bevel gear 6 synchronous rotations, and then made the table leg 2 on both sides can go up and down in step better.

Referring to fig. 1 and 2, a rotating handle 12 is rotatably connected to end faces, away from each other, of the bottoms of the supporting legs 3, a rotating shaft of the rotating handle 12 is arranged along the axis direction of the rotating handle, one end of the rotating handle 12 penetrates through the supporting legs 3 and is arranged inside the supporting legs 3, and the rotating handle 12 is coaxially and fixedly connected with an end face, away from the synchronizing rod 9, of one rotating bevel gear 6. When a user needs to adjust the height of the tabletop 1, the user rotates the rotating handle 12 to drive the rotating bevel gear 6 to rotate, so that the rotating function of the rotating bevel gear 6 is more perfect and easy to control.

Referring to fig. 1 and 2, the bottom end of the supporting leg 3 is fixedly provided with a limiting cover 7, and the lifting bevel gear 5 and the rotating bevel gear 6 are both arranged in the limiting cover 7 and movably connected with the inner wall of the limiting cover 7. When the user need adjust desktop 1 height, rotate bevel gear 6 and rotate and drive bevel gear 5 and rotate, spacing cover 7 makes bevel gear 5 and the meshing connection relation between rotating bevel gear 6 more firm this moment, and then makes bevel gear 6 can drive bevel gear 5 better and rotate.

Referring to fig. 1 and 2, the lifting screw 4 is coaxially sleeved with a lifting spring 8, the top end of the lifting spring 8 is fixedly connected with the bottom end of the table leg 2, the bottom end of the lifting spring 8 is fixedly connected with the upper end of the supporting leg 3, and when the table leg 2 is arranged at the highest position, the lifting spring 8 is in a normal state. When table leg 2 and supporting leg 3 relative movement, lifting spring 8 takes place to be deformed, and when table leg 2 rose, lifting spring 8 resumeed normal condition gradually, provides ascending thrust for table leg 2, and then makes table leg 2 can more smoothly place in the vertical direction and move.

The implementation principle of the desk with the adjustable height in the embodiment of the application is as follows: when the user needs to adjust the height of the desktop 1, the user rotates the rotating handle 12 to drive the rotating bevel gears 6 to rotate, the synchronizing rod 9 fixedly connects the two rotating bevel gears 6, so that the two rotating bevel gears 6 synchronously rotate, the rotating bevel gears 6 rotate to enable the lifting bevel gears 5 to rotate and further drive the lifting screw rods 4 to rotate along the axis direction of the lifting screw rods, the lifting screw rods 4 further drive the desk legs 2 to move in the vertical direction, so that the height of the desk legs 2 is changed, the desk legs 2 drive the desktop 1 to move in the vertical direction, and the height adjusting function of the office desk is realized.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
