Description

Technical Field

[0001] The utility model relates to a split connection structure of a protective fence and belongs to the technical field of protective fences. Background Art

[0002] As modern and automated production technology becomes more and more mature, people pay more and more attention to production protection. Now protective fences have been used for various robot workstation protection, special equipment protection, warehouse storage protection, transmission line production protection, etc. It is generally composed of protective fence mesh and columns. There are many ways to connect the fence and the column, most of which are connected by connectors. For example, Chinese patent CN 209163601 U discloses a column clamping connection device, which is simple and convenient to set with bolts; reinforcing ribs are provided at the threaded holes to enhance the strength of the parts; the connection device is provided with an opening to reduce the damage to the parts caused by deformation during installation or other situations. Although this connection method is stable, it needs to be inserted from one end of the column during installation. If it needs to be removed, all components related to the connector need to be removed, and then the connector needs to be taken out from one end. It is inconvenient to install and disassemble, time-consuming and has poor versatility. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides a connector A and a connector B separately to facilitate installation and disassembly, and also provides a connector C to meet the use requirements of the T-shaped fence.

[0004] The technical solution adopted by the utility model is a split connection structure of a protective fence, including a connector A, a connector B, a carriage bolt and a flange nut. The connector A and the connector B are arranged relatively to each other and are detachably connected through a first connection end. The second connection ends of the connector A and the connector B are both provided with screw holes, and the carriage bolts are fastened by the flange nuts after passing through the screw holes.

[0005] Furthermore, the first connecting ends of the connecting member A and the connecting member B are alternately concave and convex and snap-fitted.

[0006] Furthermore, when the connector A and the connector B are snap-fitted together, they form a hollow structure without an upper cover or a lower cover.

[0007] Furthermore, threaded holes for bolts to pass through are reserved on the opposing outer surfaces of the connector A and the connector B.

[0008] Furthermore, the threaded holes of the connector A and the connector B are provided with outwardly protruding reinforcing ribs, which, on the one hand, are conducive to enhancing the structural strength of the connector A and the connector B and reserving installation gaps, and on the other hand, increase the number of thread turns of the threaded holes.

[0009] Furthermore, a connecting member C is provided inside the second connecting ends of the connecting member A and the connecting member B. The connecting member C is in an arch shape. When the carriage bolt connects the connecting member A and the connecting member B, the carriage bolt is stuck on the side of the connecting member C.

[0010] Furthermore, the connecting member C is also provided with a connecting hole.

[0011] The utility model discloses a split connection structure for a protective fence, which has the beneficial effect that, compared with the prior art, a connector A and a connector B are separately arranged, which facilitates installation and disassembly, improves work efficiency, and shortens construction time. In addition, a connector C and a connection hole are arranged to meet the use requirements of a T-shaped fence. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] In order to further understand the utility model content of the utility model, this technical solution is further explained below in combination with specific implementation methods.

[0019] Embodiment 1:

[0020] like Figures 1 to 3 As shown, this embodiment provides a split connection structure of a protective fence, including a connector A1, a connector B2, a carriage bolt 3 and a flange nut 4. The connector A1 and the connector B2 are arranged opposite to each other and are engaged through the first connecting end with the concave and convex staggered snap-fit. When the connector A1 and the connector B2 are snap-fitted, a hollow structure without an upper cover and a lower cover is formed. The second connecting ends of the connector A1 and the connector B2 are both provided with a screw hole 5. A connector C8 is installed between the connector A1 and the connector B2 on the inner side of the end where the screw hole 5 is located. The shape of the connector C8 is an arch. The connector C8 is also provided with a connecting hole 9. When it is necessary to build a T-shaped fence 10, it is connected together through the connecting hole 9.

[0021] The outer surfaces of the connector A1 and the connector B2 are provided with threaded holes 6 for bolts to pass through, and the fences 10 on the left and right sides are connected together through the threaded holes 6. The threaded holes 6 are also provided with outwardly protruding reinforcing ribs 7, which are beneficial to enhancing the structural strength of the connector A1 and the connector B2 on the one hand, and increasing the number of thread turns of the threaded holes 6 on the other hand.

[0022] When installation is required, the connector A1 and the connector B2 are placed on both sides of the column 11, and the first connecting ends of the connector A1 and the connector B2 are engaged with each other, and then the connector C8 is placed against the other side of the column 11, and the carriage bolt 3 passes through the screw hole 5 and is fastened by the flange nut 4. When the carriage bolt 3 connects the connector A1 and the connector B2, the carriage bolt 3 is stuck on the side of the connector C8. When disassembly is required, the disassembly can be completed by simply unscrewing the bolts and taking out the components.
