Referring to fig. 8 to 9, fig. 8 is a schematic cross-sectional view illustrating a to-be-lifted member and a lifting device connected according to an embodiment of the present disclosure, and fig. 9 is an enlarged schematic view of a portion a in fig. 8.
Considering that there are many mechanical structures of the lifting mechanism 120 capable of adjusting the height of the member to be lifted 130, for example, the lifting mechanism 120 includes a lifting motor connected to the member to be lifted 130 to drive the member to be lifted 130 to move in a lifting manner. In order to adjust the supporting length of the member to be lifted 130 in cooperation with the supporting mechanism 110, in some embodiments, the lifting mechanism 120 includes a supporting frame, a screw 122, and a transmission element 123.

In this embodiment, the supporting frame is a long strip plate-shaped structure, and the first connecting seat 112 is fixedly connected to the supporting frame by a screw.
The screw 122 serves as one of the transmission elements 123 in the lifting mechanism 120, which is used for power transmission between the components. The screw 122 is connected to the support frame, specifically, the screw 122 is fixedly connected to the support frame, for example, one end of the screw 122 can be fixedly connected to the support frame by welding, it should be noted that, here, the screw 122 is fixed to the support frame, that is, the screw 122 and the support frame form a whole, and the screw 122 does not generate any form of movement relative to the support.
The transmission element 123 serves as a further transmission element 123 in the lifting mechanism 120 for power transmission between the components. The transmission element 123 is sleeved on the screw rod 122 and connected to the member to be lifted 130, specifically, the transmission element 123 is in threaded connection with the screw rod 122, mechanical transmission exists between the transmission element 123 and the screw rod 122, and since the screw rod 122 is fixedly connected to the support frame, the mechanical transmission between the transmission element 123 and the screw rod 122 is specifically represented in a manner that the transmission element 123 reciprocates along the axial direction of the screw rod 122.
The transmission element 123 can reciprocate along the axial direction of the screw rod 122, and then drives the to-be-lifted component 130 to move up and down, that is, the transmission element 123 moves towards the direction close to or far away from the support frame along the axial direction of the screw rod 122 under the action of power, the transmission element 123 is connected with the to-be-lifted component 130, so as to drive the to-be-lifted component 130 to move up and down along the axial direction of the screw rod 122 along with the transmission element 123, and then adjust the height of the to-be-lifted component 130. Specifically, the transmission element 123 includes a threaded sleeve in threaded connection with the lead screw 122, and an installer can directly rotate the threaded sleeve with the aid of a wrench or other tools to move the threaded sleeve along the axial direction of the lead screw 122 to drive the to-be-lifted component 130 to move up and down, and of course, the transmission element 123 may further include a gear in meshed connection with the threaded sleeve, the gear is coaxially and fixedly connected with a spindle of a motor, the motor is installed on the housing of the to-be-lifted component 130, and the motor rotates to drive the gear to rotate, and the gear rotates to drive the threaded sleeve meshed with the gear to move along the axial direction of the lead screw 122 while rotating around the circumferential direction of the lead screw 122, so as to drive the to-be-lifted component 130 to move up and down. In the design, the transmission element 123 reciprocates along the axial direction of the screw rod 122, and the transmission element 123 is connected with the part 130 to be lifted, so as to drive the part 130 to be lifted to move up and down along the axial direction of the screw rod 122 along with the transmission element 123, and further adjust the height of the part 130 to be lifted.
With continued reference to fig. 8-9, further, considering that the transmission element 123 may be directly connected to the member to be lifted 130, for example, the transmission element 123 may be directly and fixedly connected to the member to be lifted 130 by welding, in some embodiments, the lifting mechanism 120 further includes a connecting member 124, and the transmission element 123 is connected to the member to be lifted 130 by the connecting member 124, that is, the connecting member 124 is configured to achieve an indirect connection between the transmission element 123 and the member to be lifted 130. In this design, the connecting member 124 reduces the difficulty of installing the member to be lifted 130.
Further, considering that the connecting member 124 serves as an intermediate connecting member for connecting the transmission element 123 and the member to be lifted 130, the connecting member 124 may be connected between the transmission element 123 and the member to be lifted 130 in a snap-fit manner. It will be appreciated that, during the reciprocating movement of the transmission element 123 in the axial direction of the screw 122, one end of the connecting member 124 is connected to the transmission element 123, so that the connecting member 124 reciprocates along the axial direction of the screw 122 under the action of the transmission element 123, the other end of the connecting member 124 is connected with the member to be lifted 130, so that the member to be lifted 130 is lifted and lowered along the axial direction of the screw 122 by the connecting member 124, in some embodiments, the connecting member 124 is a flat bearing, which includes a first bearing ring 1241, a second bearing ring 1242, and a plurality of (two or more) balls 1243 disposed between the first bearing ring 1241 and the second bearing ring 1242, one of the first bearing ring 1241 and the second bearing ring 1242 is connected to the transmission element 123, and the other of the first bearing ring 1241 and the second bearing ring 1242 is connected to the member to be lifted 130. Specifically, the first bearing ring 1241 abuts the transmission element 123, and the second bearing ring 1242 abuts the member to be lifted 130. In the design, the transmission element 123 is connected with the first bearing ring 1241, the to-be-lifted member 130 is correspondingly connected with the second bearing ring 1242, and the first bearing ring 1241 and the second bearing ring 1242 are connected through the balls 1243, so that the transmission element 123 drives the to-be-lifted member 130 to move up and down along the axial direction of the screw 122, the connecting member 124 converts sliding friction between the transmission element 123 and the to-be-lifted member 130 into rolling friction, so as to reduce friction between the transmission element 123 and the to-be-lifted member 130, so that the to-be-lifted member 130 moves more smoothly along the axial direction of the screw 122, and simultaneously, the service lives of the first transmission element 123 and the to-be-lifted member 130 are prolonged.
