Description

Technical Field

[0001] The utility model relates to the field of construction equipment, in particular to a combined adjustable support. Background Art

[0002] Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, concrete and other materials are poured into a mold to form a predetermined shape. When pouring concrete, support devices are often used for auxiliary support to prevent structural collapse in the construction project. Support devices are widely used in various construction projects.

[0003] However, most of the current group supports have the following problems:

[0004] First, the existing supports are inconvenient to combine and adjust during use. Therefore, when the height is not enough, most of them are raised by adding wooden boards or other items at the bottom of the supports. However, the support is easily offset and tilted during the raising process, resulting in unstable supports, low safety in use, and inconvenient to raise the support conveniently according to the use situation.

[0005] Second, the existing supports, when supporting and fixing, mostly install a top plate at the end for fitting support, but when supporting in a relatively narrow position, a larger or smaller top plate will affect the support stability, and it is inconvenient to replace the size of the top plate according to the usage.

[0006] Therefore, the applicant has made improvements to this and proposed a combined adjustable support. Utility Model Content

[0007] In view of the problems in the prior art that it is inconvenient to conveniently raise the top plate according to usage and it is inconvenient to replace the size of the top plate according to usage, the purpose of the utility model is to provide a combined adjustable support to improve the above problems.

[0008] A combined adjustable support comprises a support seat, the support seat is rotatably connected to a rotating member, the rotating member is fixedly connected to a first gear, the first gear is meshedly connected to a second gear, the second gear is fixedly connected to a threaded rod, the threaded rod is rotatably connected to the support seat, the threaded rod is threadedly connected to a threaded sleeve, the threaded sleeve is provided with a guide tube, the guide tube is fixedly connected to the support seat, a sliding groove is opened in the guide tube, a limiting block is arranged in the sliding groove, the limiting block is fixedly connected to the threaded sleeve, the threaded sleeve is fixedly connected to a connecting block, a spring is fixedly connected in the connecting block, the other end of the spring is fixedly connected to a limiting plate, a pull rod is fixedly connected to the limit plate, a clamping block is fixedly connected to the pull rod, a support plate is provided on the connecting block, and connecting screw holes are opened on the guide tube and the threaded sleeve.

[0009] Preferably, the rotating member is fixedly connected to the center of the first gear, and the center line of the first gear and the center line of the second gear are on the same horizontal line.

[0010] Preferably, the side end surface of the limit block is in contact with the side end surface of the slide groove, and the limit blocks are symmetrically distributed on the left and right sides of the threaded sleeve.

[0011] Preferably, the cross section of the connecting block is "T"-shaped, and the side end surface of the limiting plate fits with the inner side surface of the connecting block.

[0012] Preferably, the pull rod is fixedly connected to the center of one side of the limiting plate, and the clamping blocks are symmetrically distributed on the left and right sides of the pull rod.

[0013] Compared with the prior art, the advantages and beneficial effects of the utility model are as follows:

[0014] 1. By setting the threaded rod, when adjusting the height of the support, the rotating part on the support seat can be rotated to drive the first gear to rotate. When the first gear rotates, it can smoothly drive the threaded rod to rotate through the second gear. When the threaded rod rotates, it can push the threaded sleeve to move. When the threaded sleeve moves out of the guide tube, it can be supported by the limit block in the slide groove and move smoothly. When the threaded sleeve moves upward, it can increase the length of the equipment. It can be adjusted according to the usage. And by using the multiple connecting screw holes on the guide tube, it can be combined and connected by the plate and bolts to avoid tipping.

[0015] 2. When replacing the used support plate through the provided connecting block, the pull rod can be pulled to drive the limit plate to move. When the limit plate moves, it can squeeze the spring in the connecting block, and the block on the pull rod can be detached from the support plate. When the support plate is unobstructed, the support plate can be taken out for replacement. When installing support plates of other sizes, the support plate is slid on the connecting block, the pull rod is released, and the limit plate is reset under the push of the spring. When the limit plate is reset, the pull rod can be pulled down, and the pull rod can drive the block to be stably engaged in the support plate, so as to engage and limit the replaced support plate. The support plate can be replaced and used according to the usage. BRIEF DESCRIPTION OF THE DRAWINGS
