Description

Technical Field

[0001] This utility model belongs to the field of table and chair technology, specifically a table that improves ease of use. Background Technology

[0002] Tables are an indispensable piece of furniture, serving multiple functions such as work, study, and dining. Traditional table designs often have some inconveniences. For example, tables used daily are usually placed in one place and moved to make room when needed. However, most tables have upright legs, making them very inconvenient to move. Some tables use casters on their legs for easy movement, but casters have poor locking performance, making the table very unstable. Therefore, based on the above problems, we propose a more convenient table that can not only be placed stably but also be easily moved as needed. Utility Model Content

[0003] To address the above problems, this utility model provides a table that improves ease of use, solving the inconvenience of existing tables such as difficulty in moving them and poor locking stability.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A table that improves ease of use includes a tabletop, a base connected to the bottom of the tabletop via a connecting column, a number of support legs at the bottom of the base, and a number of movable mechanisms that can be extended and retracted vertically to facilitate movement.

[0006] The movable mechanism includes a movable sleeve that can be raised and lowered, with a mounting base fixedly installed at the bottom of the movable sleeve, and a rolling element movably installed inside the mounting base.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: the supporting legs can make the entire table stable. When it is necessary to move its position, the movable mechanism can be extended, the rolling part will contact the ground, and the supporting legs will be lifted off the ground. At this time, the entire table can be moved flexibly, so as to easily move the table to a suitable position. It is very convenient in use.

[0008] As a further improvement to the above solution, the movable mechanism also includes a connecting base plate that is fixedly disposed with the base, the movable sleeve is movably disposed in the fixed seat, a control shaft is rotatably disposed in the fixed seat, the control shaft and the movable sleeve are threaded together, and the bottom of the control shaft can contact the top of the mounting seat.

[0009] The improved technology achieves the following effect: by using a control shaft, the shaft can be pushed downwards during rotation, thus achieving vertical lifting.

[0010] As a further improvement to the above solution, a drive source is fixedly installed inside the base. The output shaft of the drive source is connected to several control shafts, and a transmission component for driving its rotation is installed on the control shaft.

[0011] The improved technology achieves the following effects: The drive source provides the driving force for the extension and retraction of the moving mechanism, and the transmission assembly effectively enables all control axes to rotate synchronously, thereby achieving synchronous extension and retraction control of all moving mechanisms.

[0012] As a further improvement to the above scheme, the movable sleeve is provided with several sliding grooves, and the inner wall of the fixed seat is provided with several guide platforms that cooperate with the sliding grooves.

[0013] The improved technology has the following effect: with the cooperation of the guide table and the slide, the movable sleeve can achieve stable linear extension and retraction.

[0014] As a further improvement to the above scheme, the upper end of the control shaft is provided with a square shaft section, and the bottom end is provided with a concave indentation, which fits into the surface of the mounting base.

[0015] As a further improvement to the above solution, the transmission assembly includes a transmission box that is fixedly disposed between itself and the fixed base, and a gear set that drives the output shaft of the drive source and the control shaft within the transmission box.

[0016] The above-mentioned improvements have the following effects: the square shaft section is mainly designed to facilitate connection with the gear set, while the recessed opening at the bottom of the control shaft can prevent the control shaft from squeezing the mounting base and avoiding interference. The transmission box is divided into upper and lower halves, which can stably install and transmit the gear assembly.

[0017] As a further improvement to the above solution, the mounting base includes an upper concave surface protruding upwards and a lower concave surface protruding downwards. A through hole is provided on the lower concave surface, and the mounting base also has a movable cavity for mounting the rolling element.

[0018] The improved technical effect is that the movable cavity can stably install the rolling element in the mounting base, and the upper and lower concave surfaces limit the rolling element, preventing it from detaching from the mounting base while ensuring that it can roll.

[0029] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0030] like Figure 1-9 As shown, the specific solution of this embodiment is: a table that improves the convenience of use, including a tabletop 10, a base 11 connected to the bottom of the tabletop 10 by a connecting column 12, a plurality of supporting legs 13 provided at the bottom of the base 11, and a plurality of movable mechanisms 14 that can be extended and retracted up and down to facilitate movement at the bottom of the base 11.

[0031] The movable mechanism 14 includes a movable sleeve 1401 that can be raised and lowered. A mounting base 1402 is fixedly provided at the bottom of the movable sleeve 1401. A rolling element 1403 is movably arranged inside the mounting base 1402. In this embodiment, the rolling element 1403 is a rolling ball. The mounting base 1402 is mainly used to install and limit the rolling ball. When the movable sleeve 1401 extends the rolling element 1403 downward, the support foot 13 can be lifted off the ground. Under the action of the rolling element 1403, the base 11 can be supported. Therefore, when pushing the table, the table can be easily moved to a suitable position. During normal use, the movable mechanism 14 retracts upward, and the table can be kept stable under the support of the support foot 13 without shaking, thereby increasing the convenience of the table during use.

[0032] The structure of mounting base 1402 can be referred to in the appendix. Figure 6 As shown, it includes an upper concave surface 14021 protruding upwards and a lower concave surface 14022 protruding downwards. The lower concave surface 14022 has a through hole, and the mounting base 1402 also has a movable cavity 14023 for mounting the rolling element 1403. The movable cavity 14023 serves to accommodate the mounting base 1402. Under the action of the upper concave surface 14021 and the lower concave surface 14022, the rolling element 1403 can be stably mounted in the mounting base 1402 to prevent it from falling off. At the same time, when the table is pushed, the rolling effect of the rolling element 1403 can be maintained.

[0033] As a preferred embodiment of the above embodiment, the movable mechanism 14 further includes a connecting base plate 1404 that is fixedly disposed between the movable mechanism 14 and the base 11. The connecting base plate 1404 is fixedly disposed between the movable mechanism 1404 and the base 11 by means of screws. The movable sleeve 1401 is movably disposed within the fixed seat 1405. For details, please refer to the attached drawing. Figure 7 , 8 As shown, the movable sleeve 1401 is provided with several sliding grooves 1407, and the inner wall of the fixed seat 1405 is provided with several guide platforms 1408 that cooperate with the sliding grooves 1407. A control shaft 1406 is rotatably installed inside the fixed seat 1405. The control shaft 1406 and the movable sleeve 1401 are threaded together, and the bottom of the control shaft 1406 can contact the top of the mounting base 1402. Therefore, when the control shaft 1406 is rotated, the movable sleeve 1401 can be driven to slide linearly up and down within the fixed seat 1405. The bottom of the control shaft 1406 only contacts the movable sleeve 1401 when the movable sleeve 1401 is retracted into the fixed seat 1405, which has the effect of restricting the upward retraction of the movable sleeve 1401.

[0034] As a preferred embodiment of the above embodiments, a drive source 15 is fixedly disposed inside the base 11, such as... Figure 3As shown, the drive source 15 specifically includes a drive motor connected to a reducer. The output shaft of the drive source 15 is connected to several control shafts 1406, and a transmission assembly for driving the rotation of the control shafts 1406 is provided. The transmission assembly includes a transmission box 1411 fixedly disposed between the drive source 15 and the fixed base 1405. The transmission box 1411 is divided into upper and lower parts, which are bolted together and fixed to the top of the fixed base 1405. The transmission box 1411 contains a gear set that drives the output shaft of the drive source 15 and the control shafts 1406. See the attached diagram for details. Figure 4 , 5 It shows a schematic diagram of the internal structure of the gear set, specifically the use of bevel gear transmission, and includes... Figure 4 , 5 The configuration shown is a direct connection between the drive source 15 and the output shaft, which uses three bevel gears. The other two indirectly connected transmission components are connected to only two bevel gears, and their specific arrangement can be determined according to the intended location.

[0035] To ensure stable transmission between the bevel gear and the control shaft 1406, a square shaft section 1410 is provided at the upper end of the control shaft 1406. The square shaft section 1410 is inserted into the mounting hole of the bevel gear. A concave recess 1409 is provided at the bottom end of the control shaft 1406. The recess 1409 fits against the surface of the mounting base 1402. The recess 1409 is designed as a concave arc surface to reduce the pressure after the mounting base 1402 and the control shaft 1406 are pressed together, thus preventing damage to the mounting base 1402.
