Detailed Description
The following describes in detail a specific embodiment of the present invention with reference to fig. 1, 2, 3, 4, and 5.
Example 1: an automatic lifting table.
As shown in fig. 1, 2, 3, 4 and 5, a manual/automatic lifting table comprises a table top (not shown in the figure) and a support 1 for supporting the table top, a support leg 2 for supporting the support 1 and a table leg 21 sleeved in the support leg 2; a supporting plate 3 is fixed on the side edge of the supporting leg 2, two supporting shafts 31 are fixed on the supporting plate 3, and the outer ends of the supporting shafts 31 are fixed with the shaft seat 4; the lower part of the shaft seat 4 is connected with a motor 5; the middle of the shaft seat 4 is provided with a shaft sleeve 6, the middle of the shaft sleeve 6 is provided with a shaft core 7, the shaft core 7 is fixed at one end of a screw rod 8, and the screw rod 8 penetrates through the supporting leg 31 and is connected with a lifting mechanism arranged in the supporting leg 31.
Two supporting seats 41 are fixed on the surface of the shell of the shaft seat 4, and round holes 42 are formed in the supporting seats 41; the front ends of the two support shafts 31 extend into the circular holes 42 and are fixed to the support 41.
A through hole 32 is formed in the middle of the support plate 3, and the screw rod 8 passes through the through hole 32.
The motor 5 is mechanically connected with a shaft sleeve 6 in the shaft seat 4 through a transmission part and can drive the shaft sleeve 6 to rotate.
The inner circumference of the shaft sleeve 6 is provided with an inner rack 61, and the outer surface of the shaft core 7 is provided with an outer rack 71 matched with the inner rack 61; the front end of the inner rack 61 is an inwards concave circular inclined plane, and a tooth groove of the inclined plane part is in a pointed rhombus shape; the rear end of the outer rack 71 is a circular inclined plane, and the rack of the inclined plane part is in a pointed rhombus shape.
The front end of the inner rack 61 of the shaft sleeve 6 is processed into an inwards concave circular inclined plane, the tooth groove of the inclined plane part is in a pointed cone rhombus shape, the rear end of the outer rack 71 of the shaft core 7 is a circular inclined plane, and the rack of the inclined plane part is in a pointed cone rhombus shape, so that the gear is conveniently and quickly meshed and is also prepared by precise calculation and precise processing; that is, when the elevation is switched from manual to automatic, the screw 8 moves backward, and the external rack 71 of the shaft core 7 can be engaged with the internal rack 61 of the shaft sleeve 6 at one time.
The front end of the shaft seat 4 is provided with a concave ring 43, and the front end of the shaft sleeve 6 is provided with a flange 62 matched with the concave ring 43; the recessed ring 43 and the flange 62 are used for positioning when the bushing 6 is mounted.
A positioning pin 81 is arranged in the middle of the screw rod 8; the positioning pin 81 is used for automatically switching to manual positioning, namely when the screw 8 is pushed forwards and the positioning pin 81 reaches the side edge of the supporting leg 2, the inner rack 61 of the shaft sleeve 6 is completely separated from the outer rack 71 of the shaft core 7.
The tail end of the screw rod 8 is provided with a handle 82; the handle 82 is used for manually lifting the table top.
The shell surface of the motor 5 is provided with a control button 51; the motor 5 is connected with a power supply through a lead.
When the desk is in an automatic lifting state, the internal tooth bar 61 of the shaft sleeve 6 is completely meshed with the external tooth bar 71 of the shaft core 7, when the desk needs to be lifted, the motor 5 rotates by pressing the button 51 on the shell of the motor 5 to drive the shaft sleeve 6 to rotate, then the shaft core 7 is driven to rotate, the shaft core 7 drives the screw rod 8 to rotate, and the screw rod 8 drives the lifting mechanism to rotate, so that the desktop is lifted or lowered.
Example 2: the table is lifted manually.
When power is off, or in places without electricity, only the manual lifting table can be used.
