Table leg

The invention relates to a table foot, in particular to a hollow foot column which is supported by an adjustable foot base. The support will not sag, and it will not bend when it is supported inside and outside the adjusting foot, which is convenient for adjustment and the ground Touch a stable table foot.

When the inclined legs of a general table are placed on the ground and become unstable, it is easy to make the legs often There is a height difference, most people use paper or cardboard to adjust the legs on both sides of the table bottom the height of. In addition, please refer to Figure 1-1 and Figure 1-2. In order to solve the above table The inclined table legs are prone to height differences after placement. Therefore, in order to be able to tilt the table 1 The height of the table legs 11 and the ground create stability, which will be at the ends of the inclined legs 11 of the conventional table 1. 111 is provided with a plastic sleeve 12 separately, each plastic sleeve 12 can protect the inclined table legs 11 The end 111 of each inclined table leg 11 is hollow, so that the There is no support inside the end 111. When each of the plastic sleeves 12 of the end 111 of each inclined table leg 11 is connected to Ground contact, after a long period of use, because each plastic sleeve 12 is exposed to the table 1 itself The weight and long-term wear and tear will affect the unevenness of the inclined table legs 11 after being placed. Moreover, every After the plastic sleeve 12 is worn and thinned, the inclined tables opposite to each of the places where the plastic sleeve 12 is thinned The end 111 of the foot 11 will also be worn and dented or deformed (as shown in Figures 1-3), causing various The inclined table legs 11 are unstable when placed on the ground.

At present, the industry solves the above-mentioned conventional tilting table legs 11 plus each plastic sleeve 12 The resulting shortcomings. Therefore, the industry once again researched the knowledge of the Republic of China Patent Publication No. M243990 "Desk combined table leg structure", please refer to Figure 2. The inner edge of the table leg 2 is provided with a The plastic sleeve body 21 is provided with the plastic sleeve body 21 at the lower inner edge of the table leg 2. Although the table leg 2 has overcome the conventional There is no support on the inner edge of each inclined table leg 11 and it is pressed down for a long time under the weight of the table 1 itself. The shortcomings of raw wear and depression. Thus, an internal thread 211 is provided on the inner edge of the upper and lower sections of the plastic sleeve body 21, It is matched with a supporting foot 3, wherein the upper section of the plastic sleeve body 21 faces the inner edge of the table foot 2 Established so that the bottom of the table leg 2 abuts on the top of the lower section of the plastic sleeve body 21, the supporting leg 3 has a main body 31 And a base 32. The outer edge of the main body 31 is provided with the internal thread which is connected to the inner edge of the plastic sleeve 21 under the table leg 2 211 forms a screwed external thread 311, so that the main body 31 and the table leg 2 can be screwed to each other.

In accordance with the foregoing, the plastic cover body 21 and the supporting foot 3 are additionally installed under the table leg 2 in the prior art 2. In addition to adjusting the table foot 2 when it is installed when it is found to be uneven or inclined with the ground, you can adjust The length of the main body 31 of the support foot 3 and the angle of contact with the ground can be adjusted, and the conventional one can be improved. The plastic sleeve 12 and the tip 111 of each inclined table leg 11 are worn out. On the other hand, the subject A connecting portion 312 with a spherical shape is provided at the bottom end of the base 31, and at the same time, a connecting portion 312 is fitted on the top surface of the base 32. The concave hole 321 that can be matched with the connecting portion 312 allows the base 32 to be sleeved on the main body by using the concave hole 321 The connecting portion 312 at the bottom end of 31 can rotate freely within a certain range. However, the second knowledge of the table foot 2 After use, the following shortcomings were found:

1. Since the structure of the table leg 2 is complex, the connecting portion 312 of the main body 31 is used as a universal joint, When the connecting portion 312 is used for a long time, the universal lubricity of the connecting portion 312 will not only fail and cause failure It is easy to rotate, or dirt is easily caught at the connecting portion 312, which damages the universal rotation of the connecting portion 312.

2. Since the inside of the main body 31 is hollow, its strength is weak, which makes the external thread 311 easy to be screwed It is easier to deform during the connection process. When the rotatable length of the external thread 311 rotates too far into the table leg 2 The more the inner thread 211 of the plastic sleeve body 21 is, the more force the table leg 2 bears, although However, as shown in Figure 3-1, when the exposure distance H1 of the external thread 311 of the main body 31 is too short, the The table leg 2 bears the downward pressure of the table top for a long time, and it is easy for the external thread 311 of the main body 31 and the plastic sleeve body The connection 3111 between the internal threads 211 of 21 is stuck. If it is found that the table leg 2 is not stable, The hand facing the connecting part 312 is a universal joint, which is more difficult to hold firmly, or the hand needs to adjust the main body When the external thread 311 of 31 rotates and exits toward the outside of the plastic sleeve 21, because the external thread 311 and the internal screw The connection 3111 between the grooves 211 is stuck, and it is not easy to adjust the external thread 311 of the main body 31 to exit outward.

3. If the rotatable length of the external thread 311 of the main body 31 only rotates into one point, the main body The rotatable length of the external thread 311 of 31 is toward the outside of the internal thread 211 of the plastic sleeve 21 under the table leg 2 The more, although it is convenient for the user's hand to hold the external thread 311 to rotate from the inside of the plastic sleeve 21 Adjustment, but when the table leg 2 bears the downward pressure of the desktop for a long time, it will not only make the end of the table leg 2 bear The force is not good, and the exposure distance H2 of the external thread 311 is too long, plus the external thread 311 of the main body 31 The connecting end 3112 between the internal thread 211 and the plastic sleeve 21 is subjected to the downward force of the desktop gravity (section 3-2 As shown by the arrow in the figure), the main body 31 is hollow inside and there is no support on the outside, so that the main body 31 is threaded The exposed distance H2 of the connecting end 3112 between the 311 and the internal thread 211 will deform upward (as shown in Figure 3-2), However, the deformed external thread 311 will not be able to rotate into the internal screw of the plastic sleeve 21 under the table leg 2 later. The inside of the pattern 211 is quite unfavorable for the support under the table leg 2 and will cause stress to concentrate on the external thread 311 The end of the plastic sleeve body 21 is easily damaged, which is not conducive to the support under the table leg 2 and increases without end. The replacement of the table leg 2 causes the disadvantage of cost for users.

4. Since the plastic sleeve body 21 under the table leg 2 is easily deformed due to thermal expansion and contraction, it is not easy for the external thread 311 of the main body 31 to rotate toward the inner thread 211 of the deformed plastic sleeve body 21, and it is used The adjustment is not optimal.
