DETAILED DESCRIPTION

[0025] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0026] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways other than those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1-3 As shown in , the adjustable building support device provided by the present invention includes a base 100 , a fixing pipe 200 , an adjusting pipe 300 and a fastening sleeve 400 .

[0028] The base 100 is supported on the ground or other building foundation, and the fixing pipe 200 is fixed to the top of the base 100. A threaded connection section 210 is provided at the upper end of the fixing pipe 200. The outer wall of the threaded connection section 210 is provided with external threads. A slot 211 is formed through the wall of the threaded connection section 210. The slot 211 extends downward from the upper end surface of the threaded connection section 210 along the axial direction of the fixing pipe 200.

[0029] The adjusting tube 300 is coaxially arranged with the fixed tube 200. The outer wall of the adjusting tube 300 is provided with a ridge 310 extending axially along the adjusting tube 300. The ridge 310 is provided with thread teeth 311 that mate with the external threads on the threaded connection section 210. After the adjusting tube 300 is inserted into the fixed tube 200, the thread teeth 311 on the ridge 310 fill the slot 211 of the threaded connection section 210 and mate with the external threads on both sides of the slot 211 to form a complete thread 500.

[0030] The inner wall of the fastening sleeve 400 is provided with an internal thread. When the protrusion 310 is inserted into the slot 211, the fastening sleeve 400 is threadedly connected to the formed complete thread 500. In this way, the adjusting tube 300 and the fixing tube 200 are fastened together by the fastening sleeve 400.

[0031] In actual use, when the height of the support device needs to be adjusted, the tightening sleeve 400 is first rotated downward, away from the position of the complete thread 500. At this point, the thread teeth 311 on the protrusion 310 will be disconnected from the external thread on the threaded connection section 210, allowing the adjustment tube 300 to move freely upward. After the adjustment tube 300 is roughly moved to the desired position, the adjustment tube 300 is fine-tuned to align the thread teeth 311 on the protrusion 310 with the external thread on the threaded connection section 210 to form a complete thread. The tightening sleeve 400 is then rotated to thread the tightening sleeve 400 onto the complete thread, completing the height adjustment of the support device. The entire adjustment process is simple and quick. Moreover, once secured, the adjustment tube cannot be pulled outward or pushed inward relative to the fixing tube.

[0032] Typically, a support member 600 is provided on the top of the adjustment tube 300. The support member 600 contacts and cooperates with components of the wooden or aluminum mold casting system. For example, when cooperating with the wooden mold, a slot is provided on the top of the support member 600, and the wooden block on the outside of the wooden mold is placed in the slot.

[0033] Furthermore, in order to facilitate replacement of the supporting member 600 suitable for the wooden mold or aluminum mold casting system, a sleeve 610 is preferably provided at the bottom of the supporting member 600, and the sleeve 610 is threadedly connected to the adjustment tube 300 for easy disassembly and replacement.

[0034] like Figure 4 and Figure 5 As shown, in order to facilitate processing and manufacturing, it is preferred that a mounting groove 320 is opened on the tube wall of the regulating tube 300. During actual production, the protruding strip 310 with the processed thread teeth 311 is inserted into the mounting groove 320 and fixed to the mounting groove 320 by welding.

[0035] Typically, two ridges 310 are symmetrically provided on the wall of the adjusting tube 300 about its axis, and two slots 211 are symmetrically provided on the fixing tube 200 about its axis.

[0036] For example, when two ridges 310 are provided on the adjustment tube 300, a long steel plate can be used, with threads 311 machined on either side. The steel plate is then inserted into the mounting groove 320, with the threads 311 exposed from the mounting groove 320. The contact areas between the steel plate and the mounting groove 320 are then welded. This structure securely fastens the ridges 310 to the adjustment tube 300 and facilitates fabrication.

[0037] In a preferred embodiment, the outer wall of the adjustment tube 300 is provided with scale lines 330 distributed along its axial direction. The length between the top of the fixed tube and the bottom surface of the base is fixed. When the adjustment tube moves, the total height of the support device can be easily obtained based on the scale at the intersection of the adjustment tube and the top of the fixed tube.

[0038] Further, as shown in Figure 6 The outer wall of the fastening sleeve 400 is provided with a collar 710 and an L-shaped hook 720, the axis of the collar 710 is perpendicular to the axis of the fastening sleeve 400, and one end of the L-shaped hook 720 is inserted into the collar 710. When rotating the fastening sleeve, the handle 410 can be held and rotated, which is convenient to operate.
