In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.
Example 1:
referring to fig. 1 to 3, the present embodiment provides a lifting table leg suitable for a lifting table, including: the lifting pipe, the transmission assembly arranged in the lifting pipe and the driving mechanism connected with the transmission assembly are arranged in the lifting pipe; the lifting pipe comprises an inner pipe 1, a middle pipe 2 and an outer pipe 3 which are sequentially nested from inside to outside; the transmission assembly comprises a screw rod 7 partially inserted in the inner pipe 1 and a nut 102 matched with the screw rod 7 and fixedly connected with the inner pipe 1; when the lifting table legs are applied to the lifting table, the middle pipe 2 is directly or indirectly fixedly connected with a table top plate 10 of the lifting table, and the middle pipe 2 can do lifting motion relative to the inner pipe 1 and the outer pipe 3, namely the lifting motion of the table top plate 10 is realized by the lifting motion of the middle pipe 2.
It should be noted that the inner pipe 1, the middle pipe 2 and the outer pipe 3 are all hollow structures, and further, the inner part of one end of the middle pipe 2 facing the table top 10 of the lifting table is connected with the installation box 5 in a matching manner, where the installation box 5 can be fastened and matched with the middle pipe 2 through bolts, so that the installation box 5 is firmly positioned in the middle pipe 2; the end part of the screw rod 7 extending out of the inner tube 1 is inserted into the mounting box 5, and the screw rod 7 can freely and smoothly rotate relative to the mounting box 5 through a bearing body between the mounting box 5 and the screw rod 7.
Furthermore, the driving mechanism in this embodiment includes a transmission shaft 4 having one end inserted into the mounting box 5 to drive the lead screw 7 to rotate, and a power assembly connected to the transmission shaft 4 to drive the transmission shaft 4 to rotate; for example, in an alternative case, an output bevel gear 61 is fixed to a portion where the transmission shaft 4 is inserted into the mounting case 5; and an input bevel gear 62 which is suitable for being matched with the output bevel gear 61 is sleeved on the end of the screw rod 7 which extends into the mounting box 5. In this way, the output bevel gear 61 rotates along with the rotation of the transmission shaft 4, and the output bevel gear 61 drives the input bevel gear 62 to rotate, so as to drive the screw rod 7 to rotate.
On the basis of the structure, the transmission shaft 4 can be matched with the output bevel gear 61 and the input bevel gear 62 only by penetrating through the side wall of the installation box 5, and in consideration of improving the rotation stability of the transmission shaft 4, the transmission shaft 4 and a pair of opposite box walls of the installation box 5 are matched, and two oppositely-distributed box walls of the installation box 5 facing the transmission shaft 4 are respectively provided with an installation hole for assembling the transmission shaft 4; both mounting holes are in sliding fit with the transmission shaft 4.
With the structure, a bearing structure required by rolling fit between the installation box 5 and the transmission shaft 4 can be omitted, so that the simplified structure can save cost on one hand, and on the other hand, the structure of the whole installation box 5 can be more miniaturized due to the omission of a part of the structure, and the installation box 5 is internally arranged in the middle pipe 2, so that the size of the middle pipe 2 needs to meet the installation requirement of the installation box 5, on the basis of the miniaturization of the installation box 5, the middle pipe 2 can also be synchronously miniaturized, and the middle pipe 2 is miniaturized, and the corresponding outer pipe 3 can also be miniaturized; thus, in order to effectively ensure the supporting stability of the lifting pipe on the table top plate 10, under the condition that the middle pipe 2 and the outer pipe 3 made of metal materials are preferably adopted, the material cost can be further reduced by realizing the miniaturization of the outer pipe 3 and the middle pipe 2, so that the production cost of the whole lifting leg is reduced, and the influence on the production cost of the lifting leg caused by the rising of the metal material cost is reduced.
As will be explained below, the drive shaft 4 may alternatively be of cylindrical construction; and the two mounting holes are both circular structures. In order to keep the transmission shaft 4 and the output bevel gear 61 in synchronous rotation, a foolproof design is required to be designed between the transmission shaft 4 and the output bevel gear 61, so that the transmission shaft and the output bevel gear do not rotate relatively.
In still another alternative, the section of the transmission shaft 4 is a polygonal structure; and the two mounting holes are both circular structures; a transition sleeve 41 is sleeved on the part of the transmission shaft 4 inserted into the installation box 5; the section of the inner hole of the transition sleeve 41 is of a polygonal structure matched with the transmission shaft 4; and the section of the outer wall surface of the transition sleeve 41 is a circular structure matched with the mounting hole. The lower transmission shaft 4 and the output bevel gear 61 can keep good synchronism by the structure, and the transition sleeve 41 is arranged to realize sliding fit between the transmission shaft 4 and the wall of the installation box 5.
As will be explained below, the problem of the engagement of the screw 7 with the input bevel gear 62 is:
the section of the end part of the screw rod 7 for assembling the input bevel gear 62 is polygonal; the section of the inner hole of the corresponding input bevel gear 62 is polygonal; and the input bevel gear 62 is positioned at one side end of the bearing body, which is far away from the inner tube 1, and the input bevel gear 62 is locked on the screw rod 7 through a countersunk head screw 8. The polygonal structure is designed to achieve a good synchronous motion between the screw 7 and the input bevel gear 62. The screw 7 is used for assembling a threaded hole for matching the countersunk head screw 8, the countersunk head screw 8 can be selected, the depth of an inner hole of the input bevel gear 62 is larger than the height of the screw 7 for assembling the end part of the input bevel gear 62, so that the nut part of the countersunk head screw 8 can form interference fit with the inner hole of the input bevel gear 62, and when the countersunk head screw 8 is locked with the threaded hole, the end surface of the input bevel gear 62 departing from the output bevel gear 61 is just abutted against the inner ring part of the bearing body connecting the screw 7, so that the bearing body in the embodiment bears the rotating fit between the screw 7 and the mounting box 5, and can also be used for assisting in achieving the axial positioning problem of the input bevel gear 62. In summary, in the input bevel gear 62 of the present embodiment, the countersunk head screw 8, the output bevel gear 61, and the bearing body 101 are matched together to stably match the screw rod 7, and in this case, the output bevel gear 61 and the bearing body 101 are indispensable components in the use process of the lifting table leg itself, that is, the output bevel gear 61 and the bearing body 101 existing in the use process are skillfully utilized with respect to the fixing of the input bevel gear 62, so that the purpose of simplifying the structure is achieved in another aspect.
Finally, it should be noted that the power assembly adopted in the present embodiment includes a worm wheel 9 sleeved on the transmission shaft 4, a worm engaged with the worm wheel 9, and a driving motor connected to the worm; wherein the power assembly is internally arranged in an outer shell; and both ends of the transmission shaft 4 penetrate through the side wall of the outer shell. Under this kind of structure for the both ends of transmission shaft 4 can cooperate with a lead screw 7 respectively, and concrete combination lift table needs a pair of lift leg to realize the lift of desktop board 10, therefore this embodiment can make a pair of lift leg of a lift table only adopt a power component through the condition that the both ends of transmission shaft 4 cooperate a lead screw 7 respectively, except can effectively guaranteeing a pair of lift leg in the lift in-process elevating movement's synchronism, can also reach the purpose of simplifying the structure and reduce cost.
