[0034] Example 1
[0035] like Figures 1-8 As shown, this embodiment discloses a base connection structure for connecting the upright 100 and the base 200 of a table. It includes an upright 100, a base 200, and a fixing member 300. One end of the upright 100 has a first limiting part, and the base 200 has a second limiting part. The upright 100 has a first mounting hole 110, and the base 200 has a second mounting hole 210. When the upright 100 and the base 200 are connected, the first and second limiting parts engage with each other, allowing the first mounting hole 110 and the second mounting hole 210 to automatically align. After the upright 100 and the base 200 are connected, the fixing member 300 passes through the second mounting hole 210 and the first mounting hole 110 in sequence, thereby fixing the base 200 and the upright 100 together.
[0036] like Figure 1 , 2As shown, specifically, the first limiting part includes a first limiting member 140 and a second limiting member 150 arranged at the bottom of the column 100, and a gap 120 is arranged between the first limiting member 140 and the second limiting member 150. The second limiting part includes a first limiting hole 220 and a second limiting hole 230, and a gap with the same interval is arranged between the first limiting hole 220 and the second limiting hole 230. When the column 100 and the base 200 are connected, the first limiting member 140 and the second limiting member 150 are respectively inserted into the first limiting hole 220 and the second limiting hole 230. Through the limiting action of the first limiting member 140 and the first limiting hole 220 and the second limiting member 150 and the second limiting hole 230, the first mounting hole 110 and the second mounting hole 210 can be automatically aligned, and the operator does not need to find the position of the first mounting hole 110 when installing the fixing member 300, thereby greatly improving the installation convenience and installation experience.
[0037] As shown in the drawings, Figure 3 Further, an end plate 160 is arranged on the gap 120 close to the column 100 (between the first limiting member 140 and the second limiting member 150), and the end plate 160 is parallel to the base 200.
[0038] Specifically, the column 100 is a hollow annular structure, and the cross section thereof is rectangular. The internal cavity of the column 100 is provided with an end plate 160 perpendicular to the length direction of the column 100. The end plate 160 can be a sheet metal part, which is fixed on the inner wall of the column 100 by welding. The column 100 is vertically arranged, the end plate 160 is in a horizontal position, and the base 200 is also horizontally arranged. The bottom of the column 100 is provided with notches on opposite sides, and the two notches divide the bottom of the column 100 into two parts, which respectively constitute the first limiting member 140 and the second limiting member 150, and the notches constitute the gap 120.
[0039] As shown in the drawings, Figure 3 , 4 In this embodiment, the base 200 is a groove-shaped structure with an opening facing downward, which includes a top plate 240 at the top and a side wall arranged around the lower surface of the top plate 240. Specifically, the top plate 240 is a flat plate structure.
[0040] Moreover, the base 200 further includes a support block 250, which is arranged at the middle position of the width direction of the lower surface of the top plate 240 (in the groove at the bottom) and extends along the length direction of the top plate 240. Further, the base 200 further includes two bottom feet 260, which are respectively fixed at the two end portions of the support block 250 away from the top plate 240. Specifically, the two bottom feet 260 are both disc-shaped, and when the table is placed in the normal direction, the bottom feet 260 are in direct contact with the ground.
[0041] As shown in the drawings, Figure 6、 7 In the embodiment, the first mounting hole 110 is arranged at the middle position of the end plate 160 and is located at the middle of the first limiting member 140 and the second limiting member 150. The second mounting hole 210 penetrates the top plate 240 and the support block 250 and is located at the middle position of the top plate 240 and the support block 250 and is located at the middle of the first limiting hole 220 and the second limiting hole 230. When the column 100 and the base 200 are connected, the first limiting member 140 and the second limiting member 150 are respectively butted with the first limiting hole 220 and the second limiting hole 230, so that the first mounting hole 110 and the second mounting hole 210 are automatically aligned.
[0042] In the embodiment, the fixing member 300 is a bolt, the first mounting hole 110 is a threaded hole, and the second mounting hole 210 can be a through hole. The bolt is screwed with the first mounting hole 110 after penetrating the second mounting hole 210, so as to complete the fixed connection of the column 100 and the base 200. Moreover, when the bolt is installed, the plane where the bottom (head end) of the bolt is located is higher than the plane where the bottom end of the foot 260 is located and is also higher than the plane where the lower edge of the side wall of the base 200 is located. Such a structure design can ensure that the bolt does not contact the ground when the table is placed in the normal direction, so that the column 100 is not lifted, the table is not easy to deform when being pushed in the use process, and the bolt does not directly contact the ground and is not affected by the friction force, which is beneficial to ensure the connection stability of the bolt.
[0043] As shown in FIG. 8, in the embodiment, the first mounting hole 110 is arranged at the middle position of the end plate 160 and is located at the middle of the first limiting member 140 and the second limiting member 150. The second mounting hole 210 penetrates the top plate 240 and the support block 250 and is located at the middle position of the top plate 240 and the support block 250 and is located at the middle of the first limiting hole 220 and the second limiting hole 230. When the column 100 and the base 200 are connected, the first limiting member 140 and the second limiting member 150 are respectively butted with the first limiting hole 220 and the second limiting hole 230, so that the first mounting hole 110 and the second mounting hole 210 are automatically aligned. Figure 8As shown, further, the gap 120 is tapered, with its width at the end near the base 200 being greater than its width at the end away from the base 200. The shape of the support block 250 is adapted to the shape of the gap 120. Specifically, the cross-section of the support block 250 is trapezoidal, with its width at the end near the top plate 240 being less than its width at the end away from the top plate 240. Therefore, when the first limiting member 140 and the first limiting hole 220, as well as the second limiting member 150 and the second limiting hole 230, are connected, the end of the support block 250 near the top plate 240 is engaged between the first limiting member 140 and the second limiting member 150 along the gap 120. And when the first limiting member 140 and the second limiting member 150 are fully engaged in the first limiting hole 220 and the second limiting hole 230, the first limiting member 140 and the second limiting member 150 are respectively secured on both sides of the support block 250, and the support block 250 is also fully engaged in the gap 120. Therefore, the connection between the first limiting member 140 and the first limiting hole 220, as well as the second limiting member 150 and the second limiting hole 230, not only helps the first mounting hole 110 and the second mounting hole 210 to be automatically positioned, but also effectively increases the connection stability between the base 200 and the column 100, making the connection between the base 200 and the column 100 more reliable. The tapered gap 120, which is wider at the top and narrower at the bottom, can guide the insertion of the support block 250 and ensure smooth insertion.
[0044] In addition, the connection and cooperation of the first limiting member 140 and the first limiting hole 220, as well as the second limiting member 150 and the second limiting hole 230, limit the rotation and relative lateral movement between the base 200 and the column 100; the connection and cooperation of the gap 120 and the support block 250 further restrict the relative longitudinal movement between the base 200 and the column 100.
[0045] The installation process of the base connection structure in this embodiment is as follows:
[0046] like Figure 3 As shown, during installation, the base connection structure can be inverted so that the base 200 is above the column 100;
[0047] Align the first limiting member 140 with the first limiting hole 220, align the second limiting member 150 with the second limiting hole 230, insert the first limiting member 140 into the first limiting hole 220, and insert the second limiting member 150 into the second limiting hole 230. During this process, the support block 250 is inserted into the gap 120.
[0048] like Figure 4 As shown, the bolt is then passed through the second mounting hole 210 and connected to the first mounting hole 110, thereby completing the connection between the column 100 and the base 200.
[0049] Then, the installed product is placed vertically so that the bottom feet 260 of the base 200 are in contact with the ground.
[0050] The stand 100 of the bottom foot connecting structure in the embodiment is provided with a first limiting part at one end, the base 200 is provided with a second limiting part, and the stand 100 is further provided with a first mounting hole 110, and the base 200 is provided with a second mounting hole 210. When the base 200 and the stand 100 are connected, the first limiting part and the second limiting part are matched with each other, so that the first mounting hole 110 and the second mounting hole 210 are automatically aligned, thereby eliminating the need for manually aligning the first mounting hole 110 and the second mounting hole 210, and greatly improving the installation efficiency and installation experience. The first limiting part is a first limiting piece 140 and a second limiting piece 150 provided on the stand 100, and the second limiting part is a first limiting hole 220 and a second limiting hole 230 provided on the base 200. When the stand 100 and the base 200 are connected, the first limiting piece 140 and the second limiting piece 150 are inserted into the first limiting hole 220 and the second limiting hole 230, respectively. Therefore, the first limiting part and the second limiting part not only assist in aligning the first mounting hole 110 and the second mounting hole 210, but also help to increase the connection stability of the stand 100 and the base 200. Since the base 200 is a groove-shaped structure with an opening facing downward, the plane height at the bottom end of the fixing piece 300 is higher than the plane height at the bottom feet 260 after the fixing piece 300 is installed, and the bottom of the supporting block 250 is also provided with the bottom feet 260. Therefore, when the base 200 is placed with the opening facing downward, the fixing piece 300 will not lift the stand 100, nor will it come into contact with the ground, thereby reducing the stress on the fixing piece 300 and maintaining the connection stability of the fixing piece 300. In the embodiment, one bolt is used for fixation, which has better stability compared to the form of multiple bolts in the prior art, and the wall thickness of the top plate 240 of the base 200 can be made thinner, thereby reducing the cost. Moreover, since the first limiting piece 140 and the second limiting piece 150 are inserted into the first limiting hole 220 and the second limiting hole 230, respectively, the bottom of the stand 100 is clamped into the inside of the base 200, so that the overall center is lowered, and the stability is also greatly improved.
[0051] It can be understood that the above embodiments are only exemplary embodiments adopted for illustrating the principles of the present application, and the present application is not limited thereto. Those skilled in the art can make various modifications and improvements without departing from the spirit and essence of the present application, and these modifications and improvements are also considered as the protection scope of the present application.
