Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person of ordinary skill in the art without making creative work belong to the protection scope of the present invention.

As shown in FIGS. 1 to 7, an anti-lift type elevated floor stand structure includes a base 1, a pipe body 2, a support pipe 3, and a support platform 4. A circular connecting pipe 5 is extended at the center of the bottom surface of the supporting platform 4. The circular connecting pipe 5 is embedded at the end of the supporting pipe 3 and is connected with the supporting pipe 3 in a coordinated manner, so that the supporting platform 4 and the supporting pipe 3 form one before assembly. overall.

The pipe body 2 is vertically arranged at the center position of the base 1. In order to facilitate assembly and reduce the number of parts, the pipe body 2 and the base 1 can be arranged into an integrated structure. The support tube 3 of the fixed support platform 4 passes through an adjustment unit and the tube Body connection to complete the assembly of the entire supporting foot structure.

Among them, the adjustment unit not only plays a role of connection, but also plays a role of adjusting the height of the support pipe 3. The adjustment unit includes an anti-lift adjustment nut 6, a fastening nut 7 and a fastening bolt 8. The resistance adjusting nut 6 is sleeved on the top of the pipe body 2, and a portion of the inside of the pipe body 2 is provided with a limiting groove 601 along its circumferential direction. A plurality of bolt holes 201 are provided on the outer side of the pipe body 2, and the bolts 8 are fastened. The bolt hole 201 passing through the pipe body 2 is inserted into the limiting groove 601 of the anti-lift adjusting nut 6. One end of the support tube 3 is provided with a thread, the thread length is less than or equal to 1/2 of the length of the support tube 3, and one end of the support tube 3 is threaded and threadedly connected with the anti-lift adjustment nut 6 after fastening the nut 7.

Because the wall thickness of the pipe body 2 is thin, after the fastening bolt 8 is screwed with the pipe body 2, the connection contact surface is small, and the stability of the fastening bolt 8 is poor. Therefore, a plurality of reinforcing ribs 202 are added at positions where bolt holes 201 are opened on the outside of the pipe body 2. These reinforcing ribs 202 are arranged along the axial direction of the pipe body 2 and are integrally formed with the pipe body 2, and the length thereof is consistent with the length of the pipe body 2 as an optimal structural solution. The bolt hole 201 on the pipe body 2 extends through the reinforcing rib 202, which further increases the depth of the bolt hole 201, thereby increasing the thread contact area with the fastening bolt 8. The fastening bolt 8 is passed through the reinforcing rib 202 in turn. The bolt hole 201 on the pipe body 2 is inserted into the limiting groove 601 of the anti-lift adjusting nut 6.

In the prior art, the resistance nut 6 is generally provided inside the pipe body 2 and a single fastening bolt 8 is used to maintain the relative position with the pipe body 2. When the height of the entire supporting leg is adjusted, relative movement is easy to occur. . For this reason, in this embodiment, the cross-section of the anti-lift adjustment nut 6 is set in a T shape, that is, the top of the anti-lift adjustment nut 6 is a flange 602, and the flange 602 may be annular. Shape, the middle portion of the flange 602 extends along its axial direction with a fixing pipe 603, the fixing pipe 603 is embedded in the pipe body 2 and abuts against the inner wall of the pipe body 2, and the flange 602 covers the top surface of the reinforcing rib 202 On the other hand, the width of the flange 602 may be greater than or equal to the thickness of the reinforcing rib 202 and the pipe body 2, so as to further increase the contact area between the lifting adjustment nut 6 and the pipe body 2, thereby increasing the stability between the two.

The limiting groove 601 is provided on the outer peripheral wall of the fixing pipe 603, and the distance between the limiting groove 601 and the bottom surface of the flange 602 is equal to the distance between the bolt hole 201 and the top surface of the pipe body 2, so that the center line of the limiting groove 601 and the The center line of the bolt hole 201 is on the same center line, so that the fastening bolt 8 is aligned with the limiting groove 601, and the lifting adjustment nut 6 is fixed on the pipe body 2. The length of the fastening bolt 8 is greater than or equal to the length of the bolt hole 201. The sum of the depth of the limiting groove 601 and the limiting groove 601 on the fixing pipe 603 is opened along its circumference. When the fastening bolt 8 is fixed, the fastening bolt 8 can be inserted into the limiting groove 601 at any position to achieve the fastening resistance. The function of lifting the adjusting nut 6 can be omitted, so that the operation of aligning the fastening bolt 8 and the lifting adjusting nut 6 in the prior art can be omitted.

The inner wall of the anti-adjustment adjusting nut 6 is provided with an internal thread, and one end of the external thread threaded through the lower end of the support tube 3 for fastening the nut 7 is connected to the inner thread of the anti-adjusting adjusting nut 6 to complete the entire supporting foot. Assembly work. When height adjustment is needed, first turn the fastening nut 7 to disengage from the anti-lift adjustment nut 6, and then rotate the support tube 3 to a specified height, and then rotate the fastening nut 7 to the anti-lift adjustment. The top surface of the nut 6 abuts, and the height adjustment operation is completed.

During the whole process, since the base 1, the pipe body 2, and the reinforcing rib 202 are an integrally formed structure, it guarantees that the bottom of the entire supporting foot structure is supported. stability. A plurality of fastening bolts 8 are added to fixedly connect the anti-lift adjustment nut 6 and the pipe body 2 to ensure that the anti-lift adjustment nut 6 and the pipe body 2 remain relatively stationary when the supporting leg is adjusted in height. At the same time, the existence of the reinforcing rib 202 further extends the depth of the bolt hole 201, increases the contact area with the fastening bolt 8, and ensures the connection strength between the bolt hole 201 and the fastening bolt 8.

This creation simplifies the complexity of the structure, so that the staff can simplify the alignment operation during the assembly process, reduce the installation man-hours, improve the installation efficiency, and at the same time ensure the stability of the elevated floor in the later stage when adjusting the height.
