Description

Technical Field

[0001] This utility model relates to the field of steel connectors, specifically a steel component with an irregular cross-section. Background Technology

[0002] Steel components refer to composite steel structural components that are connected by connectors and can bear and transmit loads. Compared with reinforced concrete structures, they have unique advantages. Globally, especially in developed countries and regions, steel components are being used extensively and rationally in the field of construction engineering, and the forms of components are becoming increasingly diversified.

[0003] Current irregular cross-section steel components, such as those described in patent CN217814331U, include a rectangular component fixing plate with a rectangular fixing groove inside. The bottom end of the rectangular component fixing plate is fixedly connected to a columnar component fixing plate via a telescopic rod, and the columnar component fixing plate has a columnar opening inside.

[0004] Regarding the aforementioned technologies, the inventors believe that because the telescopic rod and the column-shaped fixing plate are fixedly connected, the direction of the column-shaped fixing plate cannot be adjusted. This inability to adjust the direction of the fixing plate makes it difficult to insert columns in different directions, resulting in poor applicability of the entire irregularly shaped cross-section steel component. Utility Model Content

[0005] The purpose of this utility model is to provide a steel component with an irregular cross-section to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel member with an irregular cross-section, including

[0008] A connecting mechanism includes a bidirectional threaded column, a movable column is symmetrically threaded to the outer side of the bidirectional threaded column, a rectangular connecting seat is fixedly connected to the top of one movable column, a rotating column is rotatably connected to the bottom of the other movable column, and a cylindrical connecting seat is fixedly connected to the end of the rotating column away from the movable column, and a cylindrical hole is opened inside the cylindrical connecting seat.

[0009] An adjustment mechanism includes a receiving box rotatably connected to the outside of the rotating column, the receiving box being fixedly connected to the lower movable column, a worm gear being fixedly connected to the outside of the rotating column, a worm being meshed with the outside of the worm gear, and the worm being rotatably connected to the receiving box.

[0010] As a further embodiment of this utility model: a fixing ring is fixedly connected at the middle position of the outer side of the bidirectional threaded column, and slots are provided in a ring array on the outer side of the fixing ring, and a matching lever is inserted into the interior of a set of the slots.

[0011] As a further embodiment of this utility model: a guide block is fixedly connected to one side of each of the two sets of movable columns, and a guide rod slides through the interior of each of the two sets of guide blocks.

[0012] As a further embodiment of this invention, a limiting block is fixedly connected to the top of the guide rod.

[0013] As a further embodiment of this utility model: multiple reinforcing ribs are fixedly connected to the outer side of the rotating column in a ring array, and each group of reinforcing ribs is fixedly connected to the columnar connecting seat.

[0014] As a further embodiment of this utility model: both ends of the worm gear penetrate the receiving box, and both ends of the worm gear are provided with hexagonal grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By adopting the above-mentioned structure, the rotating column, worm wheel, and worm cooperate with each other, so that when the worm rotates, it can drive the worm wheel and rotating column to rotate. When the rotating column rotates, it can drive the cylindrical connecting seat to rotate accordingly, thereby adjusting the cylindrical hole to different directions, thus satisfying the insertion of cylindrical parts in different directions, and effectively improving the applicability of the entire irregular cross-section steel component.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4 A steel component with an irregular cross-section includes a connecting mechanism 1. The connecting mechanism 1 includes a bidirectional threaded post 101. The outer sides of the bidirectional threaded post 101 are symmetrically threaded with movable posts 102. The bidirectional threaded post 101 is configured to drive two sets of movable posts 102 to move relative to or away from each other during rotation. A fixing ring 108 is fixedly connected to the middle position of the outer side of the bidirectional threaded post 101. The outer side of the fixing ring 108 has slots 110 arranged in a circular array. A matching lever 109 is inserted into one set of slots 110. The slots 110 are configured to allow the lever 109 to be inserted, so that the lever 109 can be moved to drive the fixing ring 108 and the bidirectional threaded post 101 to rotate.

[0025] Guide blocks 111 are fixedly connected to one side of each of the two sets of movable columns 102. Guide rods 112 slide through the interior of the two sets of guide blocks 111. The guide rods 112 and guide blocks 111 are designed to guide the movement of the movable columns 102. A limit block 113 is fixedly connected to the top of the guide rod 112. The limit block 113 is designed to limit the guide rod 112, thereby reducing the probability of the guide rod 112 disengaging from the outside of the guide block 111. A rectangular connecting seat 103 is fixedly connected to the top of one movable column 102. Specifically, a rectangular slot is provided on one side of the rectangular connecting seat 103 to accommodate the insertion of rectangular parts.

[0026] On the other side, a rotating column 104 is rotatably connected to the bottom of the movable column 102. A cylindrical connecting seat 105 is fixedly connected to the end of the rotating column 104 away from the movable column 102. A cylindrical hole 106 is provided inside the cylindrical connecting seat 105 for inserting cylindrical parts. Multiple reinforcing ribs 107 are fixedly connected in a ring array on the outer side of the rotating column 104. Each group of reinforcing ribs 107 is fixedly connected to the cylindrical connecting seat 105. The reinforcing ribs 107 are used to further connect and fix the cylindrical connecting seat 105 and the rotating column 104, thereby improving the connection stability between the rotating column 104 and the cylindrical connecting seat 105.

[0027] Adjustment mechanism 2 includes a receiving box 201 rotatably connected to the outside of the rotating column 104. The receiving box 201 is fixedly connected to the lower moving column 102. A worm gear 202 is fixedly connected to the outside of the rotating column 104. A worm 203 is meshed with the outside of the worm gear 202 and rotatably connected to the receiving box 201. The worm 203 is designed to drive the worm gear 202, the rotating column 104, and the cylindrical connecting seat 105 to rotate when rotating, thereby adjusting the direction of the cylindrical hole 106. At the same time, the self-locking property of the worm 203 and worm gear 202 transmission can reduce the probability of the rotating column 104 rotating on its own. Both ends of the worm 203 pass through the receiving box 201, and both ends of the worm 203 are provided with hexagonal slots 204. The hexagonal slots 204 facilitate the insertion of an Allen wrench to adjust the rotation of the worm 203.

[0028] In use, the rectangular connector 103 allows for the insertion of rectangular parts, and the cylindrical hole 106 allows for the insertion of cylindrical parts. Then, the worm gear 203 can be rotated according to the arrangement direction of the cylindrical parts, causing the worm gear 202 and the rotating column 104 to rotate. The rotating column 104, in turn, causes the cylindrical connector 105 to rotate, thus adjusting the direction of the cylindrical hole 106 to accommodate cylindrical parts inserted in different directions. Next, the lever 109 can be inserted into the slot 110 to rotate the fixing ring 108 and the bidirectional threaded column 101. The bidirectional threaded column 101, when rotated, can drive two sets of moving columns 102 to move relative to or away from each other, thereby causing the rectangular connector 103 and the cylindrical connector 105 to move relative to or away from each other, thus satisfying the installation of rectangular and cylindrical parts with different spacing.

[0029] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
