Description

Technical Field

[0001] The utility model relates to the field of connection equipment, in particular to a cross-connecting piece of square-section profiles for oyster racks. Background Art

[0002] During the deep-sea aquaculture of oysters, due to the strong winds and waves, the aquaculture mainly adopts a frame (floating raft) for hanging. The frame is mainly composed of buoys (floating tubes), walkway boards and wood or round tubes, which are connected to each other by bundling. However, the wood or round tubes that are perpendicular to each other are all cylindrical, with a small contact area, poor stability, and cumbersome fixation. CN212697236U discloses a new type of wind and wave resistant oyster raft connecting auxiliary parts, which is suitable for artificial aquaculture floating rafts composed of cylindrical tubes arranged horizontally and vertically. It is composed of two mutually perpendicular arc-shaped thin plates; the connecting surface of the arc-shaped thin plates is a rectangular surface; the two mutually perpendicular arc-shaped thin plates are integrally formed. In order to ensure the surface contact between the connecting auxiliary parts and the cylindrical tubes, the direct contact area of ​​the two mutually perpendicular arc-shaped thin plates is not large, which can easily cause damage to the connecting auxiliary parts when the winds and waves are strong. After the connecting auxiliary parts are damaged, it is necessary to replace the auxiliary parts for both cylindrical tubes at the same time, which can easily cause waste of resources.

[0003] Compared with cylindrical tubes, square tubes have a larger contact area, but the connection and fixation between square tubes also have problems such as poor stability and easy dislocation. This requires a new type of square tube cross connector. Utility Model Content

The utility model fixes the cross-section profile in the profile fixing groove through two mutually perpendicular connecting blocks, and limits and fixes the square tube through the limiting groove, which is convenient for installation, firmly installed and highly stable.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The utility model provides a cross-connecting piece of square-section profile for oyster racks, comprising two mutually perpendicular connecting blocks, wherein the connecting block comprises an octagonal structural bottom surface and a profile fixing groove arranged on the bottom surface, wherein a limiting groove is arranged inside the profile fixing groove.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0022] The utility model provides a cross-connecting piece of square cross-section profile for oyster racks, such as Figure 1-7 , including two mutually perpendicular connecting blocks 1, the connecting block 1 includes an octagonal structural bottom surface 2 and a profile fixing groove 3 arranged on the bottom surface 2, and a limiting groove 4 is arranged inside the profile fixing groove 3.

[0023] Among them, a limiting ring needs to be set on the surface of the square tube to cooperate with the limiting groove to facilitate fixation.

[0024] The utility model realizes the installation and positioning of the square tube through the profile fixing groove 3 and the limiting groove 4, and then it can be tied with a nylon rope. The installation is convenient, the oyster rack has high stability, and the axial misalignment is not easy.

[0025] Furthermore, the profile fixing groove 3 is formed by two vertical thin plates 5 and the bottom surface 2; a first groove 4-1 is provided in the middle position of the two thin plates 5, and a second groove 4-2 is provided on the bottom surface 2 corresponding to the first groove 4-1. The first groove 4-1 and the second groove 4-2 are connected to form a limiting groove 4. The cross-sectional size of the square tube is slightly smaller than the profile fixing groove, and a limiting ring is provided on the surface for easy fixation.

[0026] Preferably, the outer side of the thin plate 5 is provided with reinforcing ribs 6, and two triangular reinforcing ribs are provided on the outer side of each thin plate 5 to increase stability.

[0027] As an embodiment of the present invention, Figure 1-2 , can be formed by SMC molding, so that the two mutually perpendicular connecting blocks 1 are formed in one piece to improve stability.

[0028] As another embodiment of the present invention, Figure 3-7 A limiting hole 7 is provided at one end of the bottom of the connecting block 1, and a positioning column 8 is provided at the other end to cooperate with the limiting hole 7. A countersunk hole 9 is provided inside the second groove 4-2, and the two connecting blocks 1 are fixed by bolts.

[0029] Preferably, there are four limiting holes 7 and four positioning columns 8, which are symmetrically arranged. When one of the connecting blocks 1 rotates 180°, the positioning columns 8 and the limiting holes 7 are locked one by one to prevent the circumferential movement of the connecting block; then the bolts passing through the countersunk holes 9 are tightened to fix the upper and lower parts of the structure.
