Description

A coffee table with a middle layer and a table top that can be raised and lowered simultaneously

Technical Field

The utility model relates to the technical field of tea tables, in particular to a tea table with a middle layer and a table top that can be lifted and lowered simultaneously.

Background Art

At present, there are coffee tables on the market that can lift the middle layer of the coffee table, but in terms of their implementation methods, some use an independent driving device to drive the lifting of the middle layer of the coffee table, and some use complex guiding structures and connection methods to connect the middle layer of the coffee table to the driving device. At present, most of them are made into two lifting systems, namely one set drives the desktop to lift, and the other drives the middle layer of the coffee table to lift. On the one hand, the product structure is complex, which increases the production cost and assembly difficulty of the product. On the other hand, during use, when the user places objects or legs on the middle layer of the coffee table, when the middle layer of the coffee table is lifted or lowered, if the objects or legs are not removed in time, it is easy to damage the objects or injure the legs. In fact, most of the usage scenarios in which the middle layer of most coffee tables is lifted require the lifting and lowering of the desktop in conjunction with the middle layer of the coffee table. If the desktop is not lifted or lowered, there is not enough space for the middle layer of the coffee table to rise, and if it falls, it will hit the foot box. Therefore, according to this application scenario, we have researched and designed a coffee table in which the middle layer and the desktop can be lifted and lowered in conjunction with each other, and which has a simple structure and low production and installation costs.

Refer to Figures 1 to 8:

The utility model discloses a coffee table with a middle layer and a desktop 1 that can be lifted and lowered at the same time, comprising a desktop 1, a foot box 2, a middle layer 3 of the coffee table, four sets of support components 200, a driving device 100, and a transmission device, wherein the driving device 100 is preferably a motor, and a foot box 2 and a middle layer 3 of the coffee table are arranged below the desktop 1, the foot box 2 is used to hide the transmission device and the driving device 100 at the bottom, and is used for foot support, the supporting component 200 comprises an outer column 4 and an inner column 5, the four outer columns 4 are equivalent to four supporting feet, which play a role in supporting the entire coffee table, wherein the inner column 5 can be slidably arranged on the inner side of the outer column 4 up and down, the lower end of the desktop 1 is fixedly connected to the inner column 5, the transmission device comprises a transmission rod 7, a gear box 8, a screw rod 9 and a guide rod 10, the guide rod 10 is provided with an internal thread, the screw rod 9 is threadedly connected to the guide rod 10, the upper end of the guide rod 10 is fixedly connected to the inner column 5, the driving device 100 is driven by the transmission rod 7 and the gear box 8 The bevel gear conversion ultimately drives the rotation of the vertical lead screw 9, and ultimately drives the guide rod 10 to rise and fall. That is, when the motor rotates, it is transmitted to the gear box 8 through the transmission rod 7, and the gear box 8 is converted into the rotation of the vertical lead screw 9 through multiple sets of bevel gears or bevel gear transmission (existing technology). The rotation of the lead screw 9 can drive the lifting of the guide rod 10, and the lifting of the guide rod 10 will drive the lifting of the inner column 5, and the upper end of the inner column 5 is fixedly connected to the desktop 1, so the desktop 1 can be driven to rise and fall. As a technical solution that distinguishes the lifting method of the middle layer 3 of the traditional coffee table, this coffee table also includes an avoidance groove 41 and a linkage component 6, and the outer column 4 is provided with an avoidance groove 41 on one side, and one side of the linkage component 6 is fixedly connected to the middle layer 3 of the coffee table, and the other side is fixedly connected to the inner column 5 through the avoidance groove 41. When the inner column 5 drives the desktop 1 to rise and fall, it can synchronously drive the middle layer 3 of the coffee table to rise and fall, that is, when the inner column 5 rises and falls, it can link and drive the outer middle layer 3 of the coffee table to rise and fall.

In the above-mentioned embodiment of the guide device, the upper end and the lower end of the inner column 5 are respectively provided with an upper guide sleeve 51 and a lower guide sleeve 52, wherein the cross-sectional shape of the upper guide sleeve 51 and the lower guide sleeve 52 is consistent with the inner cross-sectional shape of the outer column 4, so as to provide guidance when the inner column 5 is raised and lowered. At this time, the up and down lifting of the middle layer 3 of the coffee table utilizes the guidance of the inner column 5 and the outer column 4 of the coffee table itself, and the up and down sliding is faster and smoother.

Specifically, the middle layer 3 of the coffee table includes a middle layer body 31 and a connecting portion 32. The middle layer body 31 is provided with a connecting portion 32 at a position corresponding to the outer column 4. The inner sides of the four outer columns 4 correspond to a connecting portion 32 respectively. One side of the linkage guide block 61 is fixedly connected to the connecting portion 32.

As other optional embodiments, the linkage component 6 includes a linkage guide block 61, a fixing block 62, and a fixing screw 63. A fixing screw hole 64 is provided on one side of the inner column 5. One side of the fixing block 62 is fixedly connected to the connecting portion 32 of the middle layer 3 of the coffee table. A screw through hole 611 is provided on one side of the linkage guide block 61. The fixing screw 63 passes through the screw through hole 611 and the avoidance groove 41 and is fixedly connected to the fixing screw hole 64 of the inner column 5. At this time, the linkage guide block 61 is just located in the avoidance groove 41. The cross-sectional shape of the linkage guide block 61 is preferably square, but it can also be circular. The inner side of the inner column 5 can also be locked by a ram, that is, a nut and the fixing screw 63.

As some optional embodiments, the avoidance groove 41 is preferably designed as an inner guide groove and an outer guide groove, the outer guide groove is a profile groove on the outer column 4, and the inner guide groove is a component that is snapped into the outer guide groove to serve as decoration and prevent scratching the linkage component 6.

Specifically, in order to further fix the linkage assembly 6, a limiting slot 321 and a clamping slot 322 are provided on one side of the connection part 32 of the middle layer 3 of the coffee table, and a fixing plate 65 is also provided on one side of the linkage guide block 61. The linkage guide block 61 is installed on the fixing plate 65, and the fixing plate 65 is fixedly connected to the fixing block 62, and the fixing plate 65 and the fixing hole are perpendicular to each other, so that the fixing block 62 is fixedly connected to the bottom of the connection part 32, and the fixing plate 65 is inserted upward into the limiting slot 321, and the fixing screw 63 passes outward from one side of the clamping slot 322 and is finally fixed to the fixing screw 63 of the inner column 5, so that the linkage guide block 61 is clamped between the inner column 5 and the connection part 32 of the middle layer 3 of the coffee table.

Specifically, the inner side of the middle layer body 31 is provided with an array of inner frame strips 311. The setting of the inner frame strips 311 can, on the one hand, prevent water from accumulating in the middle layer 3 of the coffee table. On the other hand, when it is cold, when it is used as a heating coffee table, socks can be dried on the inner frame strips 311. The table top 1 includes a panel 101, a frame 102, and a corner connection frame 103, wherein the frame 102 and the corner connection frame 103 are connected to each other, the panel 101 is fixed to the upper ends of the frame 102 and the corner connection frame 103, and the upper end of the inner column 5 is fixedly connected to the lower end of the corner connection frame 103.

Specifically, in some cases, referring to Figures 6-8, the up and down stroke of the middle layer 3 of the coffee table after installation is consistent with the up and down stroke of the desktop 1, and this up and down stroke is less than or equal to the longitudinal height of the avoidance groove 41. If it is greater than its longitudinal height, it may cause the internal guide rod 10 and the screw rod 9 to rotate, thereby damaging the thread of the guide rod 10. Here, as a mechanism for future maintenance, an adjustment groove 651 is also provided on one side of the fixing plate 65, and the adjustment groove 651 is just connected to the screw through hole 611. The linkage guide block 61 is fixedly connected to the fixing plate 65 in a split manner. When the fixing block 62 is fixedly installed, If there is an error in the travel limit between the middle layer 3 of the coffee table and the inner column 5, the travel limit between the middle layer 3 of the coffee table and the inner column 5 can be fine-tuned by loosening the fixing screws 63 and moving the linkage guide block 61. For example, when the lowermost end travel of the middle layer 3 of the coffee table is lower than the bottom of the avoidance groove 41, it is necessary to move the connecting portion 32 of the middle layer 3 of the coffee table upward. Then, after loosening the fixing screws 63, the adjusting groove 651 of the fixing plate 65 can be moved upward. Because the adjusting groove 651 is connected to the screw through hole 611, the screw just moves downward passively. At this time, the inner column 5 is stationary, and what is adjusted is the upward fine-tuning of the middle layer 3 of the coffee table.

The up and down sliding principle of the utility model is as follows:

Analysis of the principle of the coffee table and the desktop 1 sliding upward: Referring to Figure 1-7, the driving device 100 is started by the panel 101 or the remote control, and the motor rotates in the opposite direction to drive the transmission rod 7 to rotate. The transmission rod 7 drives the vertical screw rod 9 to rotate counterclockwise through the transmission of the bevel gear of the gear box 8 or the angle box. When the screw rod 9 rotates, the guide rod 10 is moved upward, and the upward movement of the guide rod 10 synchronously drives the inner column 5 to slide upward. Because the upper end of the inner column 5 is fixedly connected to the desktop 1, it will drive the desktop 1 to slide upward synchronously. The lower end of the inner column 5 is fixedly connected to the inner middle layer 3 of the coffee table through the linkage component 6, and there is an avoidance groove 4 on the outer column 4. 1, the linkage component 6 just passes through the avoidance groove 41 and slides up and down in the avoidance groove 41, so at this time the inner column 5 will also be linked to drive the inner coffee table middle layer 3 to slide upward. At this time, the four table legs, that is, the linkage components 6 in the four outer columns 4, slide upward at the same time, which can drive the entire coffee table middle layer 3 to slide upward. Here, the upper end stroke end and the lower end stroke end of the upward sliding can be regulated by the travel switch on the circuit board, or the limit switch installed on the inner column 5, and can also be regulated by calculating the number of motor rotations (here, the forward or reverse rotation of the motor or the clockwise or counterclockwise rotation of the screw rod 9 is just an example, not limited).

The coffee table and the desktop 1 slide downward: Referring to Figure 1-7, in contrast to sliding upward, the motor rotates in the forward direction, and similarly drives the vertical screw rod 9 to rotate clockwise. At this time, the guide rod 10 is forced to slide downward, driving the inner column 5 and the desktop 1 to slide downward, while driving the linkage assembly 6 of the inner coffee table middle layer 3 to slide downward under the limit of the avoidance groove 41, and finally stop under the limit of the limit switch. Of course, an operating panel 101 is also provided in this coffee table, and its lifting and lowering can be controlled by manual control to start, pause or terminate.

The utility model sets an avoidance groove 41 on the outer column 4, sets a linkage assembly 6 between the middle layer 3 of the coffee table and the inner column 5, and the two ends of the linkage assembly 6 are fixedly connected to the middle layer 3 of the coffee table and the inner column 5 respectively. In this way, when the inner column 5 is lifted and lowered by the guide rod 10 driven by the screw rod 9, the linkage assembly 6 will synchronously drive the middle layer 3 of the outer side of the coffee table to rise and fall synchronously, and the guide device of the coffee table itself is used to guide the up and down sliding, so that the sliding of the middle layer 3 of the coffee table is more stable. The structure is simple but very practical, and two sets of driving devices 100 are omitted. The linkage assembly 6 is not connected to the internal screw rod 9, so it will not affect the lifting and lowering of the desktop 1. The cost is low and the installation is simple.

The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
