Detailed Description of the Preferred Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a steel structure engineering support, including a base 1, a support cylinder 201 is fixed on the top of the base 1, the top of the support cylinder 201 is open, and a support column 202 is slidably connected inside. An adjustment assembly 300 for limiting is installed on the outside of the support column 202, and an expansion assembly 400 for facilitating disassembly and assembly is installed on the top of the support column 202; through the use of the expansion assembly 400 on the top of the base 1, the convenience of replacing the auxiliary expansion structure can be further improved, enabling the operator to more conveniently position the position, facilitating the penetration and fixation of bolts. Through the use of the adjustment assembly 300, the I - shaped support effect can be utilized to effectively improve the actual support capacity and support stability, facilitating the layout and long - term use of the engineering support, thereby effectively improving the practicability of the steel structure engineering support.

[0024] In this embodiment, the expansion assembly 400 is a structure for facilitating the disassembly and assembly of the expansion support.

[0025] Such as Figure 1 , Figure 2 andFigure 3 As shown in the figure, the expansion component 400 includes a fixing plate 401 fixed to the top of the support column 202, a mounting block 402 fixed to the top of the fixing plate 401, two trapezoidal grooves 403 respectively opened on the front and back of the mounting block 402, an expansion piece 404 slidably connected to the outside of the mounting block 402, two trapezoidal blocks 405 fixed to the inner side of the expansion piece 404, a mounting groove 406 opened on the top of the mounting block 402, an elastic member 407 fixed to the inner side of the mounting groove 406, a limiting block 408 fixed to the other side of the elastic member 407, a limiting groove 409 opened on the inner top wall of the expansion piece 404, two spherical blocks 410 fixed to the outside of the limiting block 408, and two sliding cavities 411 opened inside the mounting block 402 and respectively for the two spherical blocks 410 to be inserted and slide.

[0026] It should be noted that both the left and right sides of the trapezoidal groove 403 are open, the outer shape of the expansion piece 404 is in an inverted U shape, and both the two sides and the bottom are open. The trapezoidal block 405 is located inside the corresponding trapezoidal groove 403 and is slidably connected to the inner side of the corresponding trapezoidal groove 403, so that the expansion piece 404 can slide to the outside of the mounting block 402 through the limiting sliding action between the two trapezoidal blocks 405 and the corresponding trapezoidal groove 403.

[0027] In addition, the elastic member 407 is a spring, both the left and right sides of the limiting block 408 are inclined planes and are symmetrically arranged, and the limiting block 408 is slidably connected to the inner side of the mounting groove 406, so that when the expansion piece 404 slides outside the mounting block 402, it can push the limiting block 408 into the inner side of the mounting groove 406 through the abutting friction action between the side surface and the inclined plane of the limiting block 408.

[0028] At the same time, the two spherical blocks 410 are symmetrically distributed front and back, the inside of the sliding cavity 411 is connected to the inside of the mounting groove 406, so that the spherical block 410 can slide normally inside the corresponding sliding cavity 411, and can play a limiting function on the limiting block 408, enabling it to move linearly up and down, and at the same time preventing the limiting block 408 from disengaging from the inner side of the mounting groove 406.

[0029] In this embodiment, the adjusting component 300 is a structure for adjusting the height of the bracket.

[0030] As Figure 1 shown in the figure, the adjusting component 300 includes a support hole 301 opened on the outside of the support cylinder 201 and penetrating front and back, a plurality of docking holes 302 opened on the outside of the support column 202 and corresponding to the position of the support hole 301, an I-shaped pin 303 inserted into the inner side of the support hole 301, two connecting plates 304 detachably connected to the outside of the support column 202, a support plate 305 fixed to the top of the connecting plate 304, and a movable pipe clamp 306 fixedly installed on the top of the support plate 305.

[0031] It should be noted that the inner diameter and shape of the support hole 301 are respectively equal to those of the docking hole 302. The I-shaped bolt 303 can be inserted between the inner sides of the support hole 301 and the corresponding docking hole 302 at the same time, and the end of the I-shaped bolt 303 can extend to the back side of the support cylinder 201, so that the I-shaped bolt 303 can support the support column 202. The movable pipe clamp 306 is a connecting structure that can connect pipe fittings with different diameters.

[0032] The working principle of the above embodiment is as follows:

[0033] When using this engineering support, pull out the I-shaped bolt 303 so that the support column 202 can slide inside the support cylinder 201. When the corresponding docking hole 302 moves to a position corresponding to the support hole 301, insert the I-shaped bolt 303 to position and support the support column 202, facilitating the subsequent work. Slide the extension piece 404 to the outside of the mounting block 402 and let the trapezoidal block 405 slide inside the corresponding trapezoidal groove 403. When the extension piece 404 fits against the outside of the limit block 408, under the action of the inclined surface, it will push the limit block 408 to move away from the extension piece 404 and push the elastic member 407 to compress. Under the elastic force recovery action of the elastic member 407, it can drive the limit block 408 to be inserted into the limit groove 409, and the operator can perceive an obvious sliding resistance, indicating that the movement is in place, and then bolts can be directly inserted for connection and fixation, achieving the effect of convenient replacement.

[0034] Compared with the prior art, for this steel structure engineering support, through the use of the expansion assembly 400 at the top of the base 1, the convenience of replacing the auxiliary expansion structure can be further improved, enabling the operator to more conveniently position the location, facilitating the insertion and fixation of bolts. Through the use of the adjustment assembly 300, the I-shaped support effect can be utilized to effectively improve the actual support capacity and support stability, facilitating the layout and long-term use of the engineering support, thereby effectively enhancing the practicality of the steel structure engineering support and solving the problem that when replacing the responsible expansion structure of the existing steel structure engineering support, manual alignment is required and the operation convenience is poor.

[0035] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
