[0003] For example, Chinese patent document CN202514944U discloses a liftable mahjong table, comprising a base, a lower support tube fixedly connected to the center of the upper part of the base, an upper sleeve slidably mounted on the lower support tube, a table top fixedly arranged on the upper part of the upper sleeve, and a pneumatic mechanism, wherein the pneumatic mechanism comprises a control rod, a control pin driven by the control rod to move up and down, an inner tube whose top is supported by a partition arranged inside the upper sleeve, and a piston rod arranged in the lower support tube.

[0004] However, the design of the above-mentioned liftable mahjong table has the following problems:

[0005] Although the above-mentioned liftable mahjong table can be raised and lowered autonomously under the adjustment of the user to meet the needs of people of different heights, when adjusting the above-mentioned liftable mahjong table, the pneumatic mechanism of each table leg needs to be adjusted one by one. Since the pneumatic mechanism is highly mobile and difficult to control, it is difficult to unify the lifting height of each table leg, which ultimately makes it difficult to place the mahjong on the liftable mahjong table stably, affecting the progress of the game. Utility Model Content

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a quantifiable lifting table frame with visible lifting height and a multifunctional household table.

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0008] A quantitatively liftable table frame comprises a table frame and a plurality of table legs; each of the table legs is arranged correspondingly at a corner of the table frame;

[0009] The table legs include a telescopic sleeve rod, a measuring inner rod and an adjusting swivel column;

[0010] A lifting slot is provided at the top of the lifting and retracting sleeve; the first end of the measuring inner rod is connected to the table frame; the second end of the measuring inner rod is slidably arranged in the lifting slot, and a scale line is provided on one side of the second end of the measuring inner rod; the adjusting screw is arranged in the lifting slot, and the first end of the adjusting screw is screwed to the second end of the measuring inner rod; the second end of the adjusting screw passes through the bottom of the lifting slot and forms a lifting knob; the lifting knob abuts against the bottom end of the lifting and retracting sleeve to push the top end of the lifting and retracting sleeve to slide along the scale line.

[0011] In one of the embodiments, the outer wall of the measuring inner rod is provided with a flat surface; the scale lines are arranged on the flat surface and extend along the length direction of the measuring inner rod.

[0012] In one embodiment, the table leg further includes a pre-positioning nut, a screw hole is formed on the top peripheral wall of the telescopic sleeve, and the pre-positioning nut passes through the screw hole; the pre-positioning nut is screwed into the screw hole and pressed against the second end of the measuring inner rod.

[0013] In one embodiment, the lifting knob and the adjusting screw are an integrally formed structure.

[0014] In one embodiment, a threaded adjustment groove is formed at the second end of the measuring inner rod, a screw-on thread is formed on the peripheral wall of the first end of the adjusting screw pin, the first end of the adjusting screw pin is located in the threaded adjustment groove, and the screw-on thread cooperates with the notch of the threaded adjustment groove.

[0015] In one embodiment, a lubricating oil chamber is formed at the first end of the measuring inner rod, and the lubricating oil chamber is connected to the threaded adjustment groove.

[0016] In one embodiment, an oil guide channel is opened in the measuring inner rod, and the liquid inlet end of the oil guide channel is connected to the bottom of the lubricating oil chamber; the liquid outlet end of the oil guide channel is close to the second end of the measuring inner rod and is connected to the threaded adjustment groove.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0032] Combine 1 picture with Figure 2As shown, a quantitative lifting table frame 10 of an embodiment includes a table frame 100 and a plurality of table legs 200; each of the table legs 200 is arranged at a corner of the table frame 100; the table legs 200 include a telescopic sleeve rod 210, a measuring inner rod 220 and an adjusting screw 230; a lifting slot 2130 is provided at the top of the telescopic sleeve rod 210; a first end of the measuring inner rod 220 is connected to the table frame 100; a second end of the measuring inner rod 220 is slidably arranged in the lifting slot 2130, A scale line 2211 is provided on one side of the second end of the measuring inner rod 220; the adjusting screw 230 is arranged in the lifting slot 2130, and the first end of the adjusting screw 230 is screwed to the second end of the measuring inner rod 220; the second end of the adjusting screw 230 passes through the bottom of the lifting slot 2130 and forms a lifting knob 2310; the lifting knob 2310 abuts against the bottom end of the lifting and retracting sleeve rod 210 to push the top end of the lifting and retracting sleeve rod 210 to slide along the scale line 2211.

[0033] It can be understood that by making the second end of the adjusting screw column 230 pass through the bottom of the lifting slot 2130 to form a lifting knob 2310, since the first end of the adjusting screw column 230 is screwed to the second end of the measuring inner rod 220, the lifting knob 2310 abuts against the bottom end of the lifting and retracting sleeve rod 210, when the user twists the lifting knob 2310, the lifting knob 2310 can drive the adjusting screw column 230 to rotate, since the first end of the adjusting screw column 230 is screwed to the second end of the measuring inner rod 220, the lifting knob 2310 abuts against the bottom end of the lifting and retracting sleeve rod 210, and the lifting knob 2310 can drive the adjusting screw column 230 to rotate. The adjusting screw 230 can move up and down relative to the measuring inner rod 220, thereby pushing the telescopic sleeve 210 to move up and down relative to the measuring inner rod 220. Because a scale line 2211 is provided on one side of the second end of the measuring inner rod 220, the top end of the telescopic sleeve 210 slides along the scale line 2211, and the top end of the telescopic sleeve 210 is indicated on the scale line 2211. The user can intuitively know the lifting and lowering amount of the telescopic sleeve 210 through the scale line 2211.

[0034] It can be understood that compared with the liftable mahjong table of the prior art, the above-mentioned quantitative liftable table frame 10 can push the lifting and contracting sleeve 210 to lift and lower relative to the measuring inner rod 220 through the lifting knob 2310, and know the extension and contraction amount of the lifting and contracting sleeve 210 through the scale line 2211, so that the lifting amount of each table leg 200 can be accurately adjusted one by one, thereby ensuring that the lifting amount of each table leg 200 remains consistent, ensuring that the table frame 100 can remain horizontal after lifting and lowering, and can better place chess and cards or mahjong. At the same time, the first end of the adjusting screw 230 is screwed to the second end of the measuring inner rod 220, which is more stable and easy to control than the pneumatic mechanism.

[0035] Combination Figure 1 and Figure 3As shown, in one embodiment, the outer wall of the measuring inner rod 220 is provided with a flat surface 2210; the scale lines 2211 are arranged on the flat surface 2210 and extend along the length direction of the measuring inner rod 220. By arranging the scale lines 2211 on the flat surface 2210, when the top end of the telescopic sleeve 210 slides along the scale lines 2211, it can be more convenient for observation, thereby accurately obtaining the lifting and lowering amount of the telescopic sleeve 210.

[0036] Combination Figure 2 and Figure 3 As shown, in one embodiment, the table leg 200 also includes a pre-positioning nut 240, and a screw hole 2120 is opened on the top peripheral wall of the lifting and retracting sleeve 210, and the pre-positioning nut 240 passes through the screw hole 2120; the pre-positioning nut 240 is screwed into the screw hole 2120 and pressed against the second end of the measuring inner rod 220, so that the second end of the lifting and retracting sleeve 210 can slide and hover at the predetermined position of the scale line 2211 by the pre-positioning nut 240, which makes it easier for users to accurately adjust the lifting amount. The predetermined position here is not limited.

[0037] Combination Figure 2 As shown, in one embodiment, the lifting knob 2310 and the adjusting screw 230 are integrally formed, so that the lifting knob 2310 is tightly connected to the adjusting screw 230, so that the lifting knob 2310 can more stably drive the adjusting screw 230 to rotate and more smoothly push the telescopic sleeve 210 to slide.

[0038] Combination Figure 2 As shown, in one embodiment, the second end of the measuring inner rod 220 is provided with a threaded adjustment groove 2220, and the peripheral wall of the first end of the adjusting screw 230 is provided with a screw thread 2320, and the first end of the adjusting screw 230 is located in the threaded adjustment groove 2220, and the screw thread 2320 cooperates with the notch of the threaded adjustment groove 2220. When the adjusting screw 230 is rotated, the screw thread 2320 cooperates with the notch of the threaded adjustment groove 2220, so that the first end of the adjusting screw 230 is lifted and lowered more smoothly along the threaded adjustment groove 2220. The screw thread 2320 and the threaded adjustment groove 2220 always keep part of them in the lifting and lowering groove 2130, so as to ensure that the part of the screwed connection position of the measuring inner rod 220 and the adjusting screw 230 is located in the lifting and lowering groove 2130, so that the inner wall of the lifting and lowering groove 2130 serves as a guide for the measuring inner rod 220 and the adjusting screw 230 during the lifting and lowering process.

[0039] Combination Figure 2As shown, in one embodiment, a lubricating oil chamber 2230 is provided at the first end of the measuring inner rod 220, and the lubricating oil chamber 2230 is connected to the threaded adjustment groove 2220, so that the lubricating oil in the lubricating oil chamber 2230 can lubricate the adjusting screw 230 in the threaded adjustment groove 2220, thereby allowing the adjusting screw 230 to rotate more smoothly.

[0040] Combination Figure 2 As shown, specifically, an oil guide channel 2240 is opened in the measuring inner rod 220, and the liquid inlet end of the oil guide channel 2240 is connected to the bottom of the lubricating oil chamber 2230; the liquid outlet end of the oil guide channel 2240 is close to the second end of the measuring inner rod 220, and is connected to the threaded adjustment groove 2220, so that the lubricating oil in the lubricating oil chamber 2230 can lubricate the first end of the adjusting screw 230 through the oil guide channel 2240, and when the first end of the adjusting screw 230 rises along the threaded adjustment groove 2220, the lubricating oil can be applied to the groove wall of the threaded adjustment groove 2220, further allowing the adjusting screw 230 to rotate more smoothly in the threaded adjustment groove 2220.

[0041] Combination Figure 1 and Figure 2 As shown, further, the table leg 200 also includes a plug 250, and an oil filling port 2250 is opened at the end of the first end of the measuring inner rod 220, and the oil filling port 2250 is connected to the lubricating oil chamber 2230. The plug 250 is arranged at the oil filling port 2250, and extends to block the liquid inlet end of the oil guide channel 2240. By placing the plug 250 at the oil filling port 2250, the lubricating oil chamber 2230 and the liquid inlet end of the oil guide channel 2240 can be disconnected in time, thereby preventing excessive lubricating oil from entering the threaded adjustment groove 2220 to cause blockage, thereby interfering with the lifting and lowering of the adjustment screw 230.

[0042] Combination Figure 2 As shown, in one embodiment, a sealing ring 2221 is provided between the notch of the threaded adjustment groove 2220 and the first end of the adjustment screw pin 230, so as to prevent the lubricating oil from leaking from the gap between the notch of the threaded adjustment groove 2220 and the first end of the adjustment screw pin 230 and being wasted.

[0043] Combination Figure 1As shown, the present disclosure also provides a multifunctional household table, including the quantifiable lifting table frame 10 of any of the above embodiments. It can be understood that by applying the quantifiable lifting table frame 10 of the present disclosure to the multifunctional household table, the lifting amount of each table leg 200 can be accurately adjusted one by one, thereby ensuring that the lifting amount of each table leg 200 remains consistent, ensuring that the table frame 100 can remain horizontal after lifting, and can better place chess and cards or mahjong.

[0044] Compared with the prior art, the present invention has at least the following advantages:

[0045] 1) The second end of the adjusting screw 230 passes through the bottom of the lifting slot 2130 to form a lifting knob 2310. Since the first end of the adjusting screw 230 is screwed to the second end of the measuring inner rod 220, the lifting knob 2310 abuts against the bottom end of the lifting and retracting sleeve rod 210. When the user twists the lifting knob 2310, the lifting knob 2310 can drive the adjusting screw 230 to rotate. Since the first end of the adjusting screw 230 is screwed to the second end of the measuring inner rod 220, The adjusting screw 230 can move up and down relative to the measuring inner rod 220, and further can push the telescopic sleeve 210 to move up and down relative to the measuring inner rod 220. Because a scale line 2211 is provided on one side of the second end of the measuring inner rod 220, the top end of the telescopic sleeve 210 slides along the scale line 2211, and the top end of the telescopic sleeve 210 will be indicated on the scale line 2211. The user can intuitively know the lifting and lowering amount of the telescopic sleeve 210 through the scale line 2211.

[0046] 2) Compared with the liftable mahjong table in the prior art, the above-mentioned quantitative liftable table frame 10 can push the lifting and contracting sleeve 210 to lift and lower relative to the measuring inner rod 220 through the lifting knob 2310, and the extension and contraction amount of the lifting and contracting sleeve 210 can be known through the scale line 2211, so that the lifting amount of each table leg 200 can be accurately adjusted one by one, thereby ensuring that the lifting amount of each table leg 200 remains consistent, ensuring that the table frame 100 can remain horizontal after lifting and lowering, and can better place chess and cards or mahjong. At the same time, the first end of the adjusting screw 230 is screwed to the second end of the measuring inner rod 220, which is more stable and easy to control than the pneumatic mechanism.

[0047] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
