Description

Technical Field

[0001] The utility model relates to the technical field of lifting tables, in particular to an inclined-leg type electric lifting table. Background Art

[0002] A lifting table is a table that can be automatically lifted and lowered by lifting table legs. The transmission mechanism of the lifting table legs (also called liftable table legs) is mainly composed of gear sets, screws, nuts, inner support tubes, outer support tubes, etc. The motor is the power source of the lifting table legs. It drives the screw to rotate through the gear set. The screw and nut cooperate to make the inner support tube and the outer support tube move up and down relative to each other, thus realizing the lifting of the lifting table legs and the lifting table.

[0003] The legs of the lift tables on the market are generally straight legs, and the most common ones are two-leg lift tables and four-leg lift tables. Two-leg lift tables usually have poor stability. When the tabletop becomes larger and the span of the two legs increases, the swing range of the lift table will also increase, reducing the user experience. Although the four-leg lift table is more stable than the two-leg lift table, it requires at least two or more motors to drive it, which increases the difficulty of control, makes the lift table more bulky as a whole, and significantly increases the cost. It can be seen that the technical development of straight-leg lift tables has entered a bottleneck period.

[0004] Therefore, it is necessary to design a substitute with high stability, that is, an electric lifting table with inclined legs. Utility Model Content

DETAILED DESCRIPTION

[0031] 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.

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0033] A slanted leg type electric lifting table 1, such as Figure 1-4 As shown, it includes a crossbeam 3 , a lifting table leg 5 and a support column 4 . The lifting table leg 5 is obliquely arranged on the crossbeam 3 ; the support column 4 is obliquely arranged on the lower side of the lifting table leg 5 .

[0034] The inclined lifting table legs 5 and the inclined supporting columns 4 are in a fork arm structure, which is a triangle or quasi-triangle shape. When supported on the ground, it has the characteristics of high stability and can be used as a substitute for a straight-leg lifting table.

[0035] The lower end surfaces of the support column 4 and the lifting table legs 5 are flush and can be supported on the ground.

[0036] The utility model also includes a motor assembly 6 and a transmission assembly 7. The motor assembly 6 is used to provide driving force and may include a motor and a reducer. The transmission assembly 7 includes a transmission rod 71 and a transmission shaft 75. A transmission shaft 75 is connected to the output end of the motor assembly 6. One end of the transmission shaft 75 is connected to the input end of a transmission mechanism 51 of a lifting table leg 5, and the other end is connected to one end of the transmission rod 71. The other end of the transmission rod 71 is connected to the input end of the transmission mechanism 51 of another lifting table leg 5 through another transmission shaft 75. Connecting a motor assembly 6 and two lifting table legs 5 through the transmission assembly 7 can reduce production costs, reduce product weight, and improve control efficiency.

[0037] More specifically, the transmission shaft 75 is connected to the transmission rod 71 via a coupling 72. The cross beam 3 includes a fixed beam 31 and a telescopic beam 32 slidably mounted on the fixed beam 31. However, the present invention is not limited thereto.

[0038] like Figure 4 The inner support tube 52 of the lifting table leg 5 is installed on the fixed beam 31 through the connecting piece 33; the support column 4 is installed on the outer support tube 53 of the lifting table leg 5. Among them, the lifting transmission mechanism of the lifting table leg 5 is the existing technology, and the utility model will not be repeated.

[0039] Figure 3 and Figure 4 Also shown is a table top 2 and an adjustment assembly 8, the adjustment assembly 8 comprising a bearing box 81, a first screw rod 82 and a first nut 85 matched with the first screw rod 82. The bearing box 81 is mounted on the cross beam 3, the first screw rod 82 is mounted on the bearing of the bearing box 81, the transmission shaft 75 or the transmission rod 71 is provided with a first gear 73, the first screw rod 82 is provided with a second gear 83 matched with the first gear 73, and the first nut 85 is mounted on the lower side of the table top 2.

[0040] When the lifting table leg 5 rises and drives the cross beam 3 to move to one side, the first screw rod 82 controls the table board 2 to move to the other side and relatively offsets the horizontal displacement of the table board 2. The gear ratio and gear direction of the first screw rod 82 should be set according to the lifting range and horizontal displacement of the lifting table leg. Conversely, when the lifting table leg 5 descends, the table board 2 can also offset the lateral movement of the cross beam 3.

[0041] like Figure 2 At least one guide assembly 9 is provided on the crossbeam 3, and the guide assembly 9 includes a matching guide rail 91 and a slider 92, and the guide rail 91 and the slider 92 are installed on the crossbeam 3 and the table top 2. The first screw rod 82 passes through the groove on the other crossbeam, and a limit block 86 is provided on the outer end of the first screw rod. A hand controller 21 is also provided on the lower side of the table top 2, and the hand controller 21 is connected to the motor assembly 6.

[0042] The utility model changes the lifting mode of the existing lifting table: inclined lowering. Its working form is: the motor assembly 6 starts to rotate after receiving the control command of the hand controller 21, and drives the transmission rod to rotate synchronously at the same time. After a series of transmissions, the support tube 52 in the table leg starts to rise (fall), and the crossbeam 3 rises (falls) accordingly. The crossbeam also moves horizontally, such as moving forward (backward). Since the first gear 73 is installed on the transmission rod 71, and the second gear 83 meshing with it is concentric with the first screw rod 82 and rigidly installed, the first screw rod 82 cooperates with the first nut 85 installed on the table board 2, and the first screw rod 82 also drives the table board to move backward (forward) to offset or partially offset the horizontal displacement of the crossbeam 3, improve the user experience during the lifting process, and avoid collisions with other objects during the lifting process. In addition, this makes the table board 2 relative to the entire electric lifting table, and the phenomenon of backward tilt (forward tilt) will never occur, which can keep the center of gravity of the table board 2 stable.

[0043] In a specific embodiment, the lower end of the lifting table leg 5 (outer support tube) is welded to the support column 4 at a certain angle, and the angle range can be between 20-60 degrees, but is not limited thereto. By adjusting the telescopic distance of the telescopic beam 32 in the fixed beam 31 and then fixing it with screws, the length span of the entire beam can be adjusted and the length of the transmission rod 71 can be adapted.

[0044] The form of the lifting table legs includes but is not limited to square legs, round legs and elliptical legs. The first screw includes but is not limited to trapezoidal screw and ball screw. The gear includes but is not limited to helical gear and staggered axis gear.

[0045] The stability and aesthetics of the utility model are improved to a certain extent, the number of motors required is reduced, the control difficulty is reduced, and the cost is lower. During the tilting and lifting process of the lifting table, the table top 2 will not tilt forward.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
