Description

Technical Field

[0001] This utility model relates to the field of cone heads for space frame members, and in particular to an improved cone head for space frame members. Background Technology

[0002] A space frame is a spatial structure composed of multiple members connected by nodes in a certain grid pattern. The basic units constituting a space frame include triangular pyramids, triangular prisms, cubes, and truncated square pyramids. It has advantages such as spatial stress distribution, light weight, high rigidity, and good seismic performance. It can be used as roofs for buildings such as stadiums, theaters, exhibition halls, waiting halls, stadium grandstand canopies, aircraft hangars, two-way large column space frame structures, and workshops. The cone head is an accessory used in bolted ball steel space frame structures. It is welded to the end of the steel pipe. The shank of the high-strength bolt passes through the bottom round hole and is screwed into the bolt ball. The nut is inside the cone head and has the same function as the end plate. When the diameter of the steel pipe is small, the end plate is used. When the diameter of the steel pipe is large, the cone head is used to avoid collision between steel pipes on the same bolt ball. The cone head or end plate and the steel pipe form the members of the bolted ball space frame structure.

[0003] A search revealed in Publication No. CN207295988U disclosed an improved conical head for space frame members, comprising a steel pipe and a sleeve. A member is welded to the upper end of the steel pipe, and a sealing plate is welded to the upper end of the sleeve. A set screw is installed on the right side of the sealing plate. A conical head baffle is welded to the right end of the sleeve. A high-strength bolt is installed inside the sleeve. A cylinder is installed inside the steel pipe, and a connecting rod is welded to the right side of the cylinder. A bracket is installed inside the steel pipe, with a first slide rail and a second slide rail installed inside. Fixing bolts are inserted into the surfaces of the first and second slide rails, and a fixing rod is welded to the lower end of each fixing bolt. A limit plate is installed inside the steel pipe. This improved conical head for space frame members has a simple manufacturing process, is quick to use, and is reliable.

[0004] Although the above solution is simple and quick to use for improving the cone head process of space frame members, it is inconvenient to carry multiple specifications of cone heads when different lengths of cone heads are needed. Furthermore, it is not convenient to disassemble, and if a part is damaged, the entire cone head needs to be replaced. Utility Model Content

[0005] The main purpose of this utility model is to provide an improved cone for space frame members. The adjustment unit solves the problem of having to carry multiple specifications of cones when different lengths of cones are needed, which is inconvenient. The assembly unit solves the problem of inconvenient disassembly and the need to replace the entire cone if part is damaged.

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

[0007] An improved cone for space frame members includes a pointed end, an adjustment unit disposed at the bottom of the pointed end, and an assembly unit disposed at the bottom of the adjustment unit.

[0009] The assembly unit includes a disassembly / removal seat disposed at the bottom of the connecting seat, a connecting component disposed on the outer side between the connecting seat and the disassembly / removal seat, and a locking component disposed on the inner side between the connecting seat and the disassembly / removal seat.

[0010] Preferably, the stabilizing component in the adjustment unit includes a support rod fixedly connected to the inside of the pointed end, a horizontal plate fixedly connected to the middle of the support rod, and inclined plates fixedly connected to both sides of the support rod.

[0011] Preferably, the limiting component in the adjusting unit includes a limiting ring fixedly connected to the bottom end of the sharp end, a plug ring fixedly connected to the bottom end of the sharp end outside the limiting ring, and threaded holes opened inside the limiting ring and the plug ring, with a limiting block fixedly connected to one side of the threaded hole opened in the limiting ring.

[0012] Preferably, the positioning component in the adjustment unit includes a fixing ring fixedly connected to the bottom of the pointed end and fitting against the inner side of the connecting seat, and a first bolt disposed inside the connecting seat and extending into the corresponding limiting block.

[0013] Preferably, the connecting components in the assembly unit include a connecting ring fixedly connected to the bottom outer side of the connecting seat, a locking ring fixedly connected to the top outer side of the disassembly seat, a snap-fit ​​block fixedly connected to the top of the locking ring and extending into the interior of the connecting ring, and a second bolt disposed on the outside of the connecting ring and extending into the interior of the snap-fit ​​block.

[0014] Preferably, the locking component in the assembly unit includes a groove formed at the bottom inner side of the connecting seat and the top inner side of the disassembly seat, an elastic post and a spring disposed inside the groove, and a first arc-shaped plate and a second arc-shaped plate respectively fixedly connected to one end of the corresponding elastic post.

[0015] Preferably, the locking assembly in the assembly unit further includes an extension post fixedly connected to the top of the first arc-shaped plate, and the extension post extends into the interior of the second arc-shaped plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. In this utility model, by setting the adjustment unit, when it is necessary to adjust the length of the cone, multiple first bolts can be removed, and then the sharp end can be moved up or down. Threaded holes of different heights can be selected and connected to the first bolts. This can change the distance between the sharp end and the connecting seat, thereby adjusting the length of the cone. This eliminates the need to carry cones of various specifications, improving the applicability of the cone. At the same time, the stability of the sharp end is improved under the action of the support rod, inclined plate and horizontal plate.

[0018] Second, in this utility model, by setting up the assembly unit, if the cone head is damaged, multiple second bolts can be removed, and then the disassembly and assembly seat can be pulled down to separate the locking ring from the connecting ring. At the same time, the disassembly and assembly seat can be separated from the connecting seat. This allows for easy removal of the disassembly and assembly seat. Removing multiple first bolts can separate the sharp end and the connecting seat. This allows for quick disassembly of the cone head, and only the damaged parts need to be replaced, thus improving the applicability of the cone head. Attached Figure Description
