Description

Technical Field

[0001] This utility model relates to the field of bolted ball joint space frame technology, and in particular to a cone head for bolted ball joint space frames. Background Technology

[0002] A "cone head" is an accessory used in bolted ball steel space frame structures. It is welded to the end of a steel pipe, and the shank of a high-strength bolt passes through its bottom hole and is screwed into the bolt ball. The nut is inside the cone head, serving the same function as a "sealing plate." Sealing plates are used when the steel pipe diameter is small, while cone heads are used to prevent collisions between steel pipes on the same bolt ball when the diameter is large. The cone head or sealing plate, together with the steel pipe, forms the "staff" of the bolted ball space frame structure. Sometimes, both sealing plates and cone heads are collectively referred to as "sealing heads." Existing cone heads used in bolted ball joint space frames cannot securely fasten bolts, have low strength, and may detach during processing, reducing processing efficiency, having a short service life, being unreliable, lacking safety performance, and having limited functionality.

[0003] Publication number CN215483584U discloses a novel conical head for bolted ball joint space frames, comprising a conical head body with an installation opening at the top and a through hole in the center of the bottom. A magnetic plate is distributed around the bottom inner side of the conical head body. The interior of the conical head body includes a steel plate layer, a polytetrafluoroethylene (PTFE) layer, a ceramic layer, and a flame-retardant layer. The steel plate layer has a flame-retardant layer inside it, a ceramic layer inside it, and a PTFE layer on the outer side of it. This relates to the field of bolted ball joint space frame technology. This novel conical head for bolted ball joint space frames facilitates fastening and adsorption during bolt installation, exhibits high stability and strength, prevents detachment during processing, improves processing efficiency, is wear-resistant and corrosion-resistant, has a long service life, high safety performance, is fire-retardant, high-temperature resistant, rationally designed, and durable.

[0004] While the above solutions prevent the cone from falling off during processing, the magnetic attraction method is not very effective in limiting the bolts, and the cone is not stable enough when welded to the steel pipe. Therefore, we propose a cone for bolt ball joint space frame. Utility Model Content

[0005] The main purpose of this utility model is to provide a cone head for bolt ball joint space frame. By setting reinforcement components and limiting components, it solves the problems that the magnetic attraction method has a general effect on bolt limiting and that the cone head is not stable enough when welded to the steel pipe.

[0006] To solve the above technical problems, this utility model is achieved through the following technical solution: a cone head for a bolt ball joint space frame, comprising a hollow cone head body and an mounting ring set on the top of the cone head body, and further comprising: a reinforcing component and a limiting component set on the cone head body, wherein a through hole is provided at the center of the bottom end of the cone head body;

[0007] The reinforcement assembly includes a plug-in ring, a transverse threaded cylinder, and a reinforcement bolt. The plug-in ring is fixedly mounted on the top surface of the mounting ring, and the transverse threaded cylinder is fixedly mounted on the inner wall of the curved surface of the plug-in ring. A positioning hole is provided on the outer circumferential surface of the plug-in ring, and the reinforcement bolt movably passes through the positioning hole and is assembled on the transverse threaded cylinder.

[0008] The limiting assembly includes a sliding rod, a slider, a support block, a lateral limiting block, and an oblique spring. Two oblique through slots are symmetrically formed on the outer circumferential surface of the cone head body. The sliding rod is fixedly mounted on the oblique through slots. The slider is movably mounted on the outer circumferential surface of the sliding rod. The support block is fixedly mounted on the side of the slider. The lateral limiting block is fixedly mounted on the end face of the support block and located inside the cone head body. The oblique spring is fixedly mounted between the top surface of the support block and the top wall of the oblique through slot.

[0009] Preferably, there are two transverse threaded cylinders arranged symmetrically on the insertion annular surface, and the reinforcing bolts and positioning holes are arranged in a one-to-one correspondence with the transverse threaded cylinders.

[0010] Preferably, the support block, the lateral limiting block, and the oblique spring are arranged in a one-to-one correspondence with the oblique through groove.

[0011] Preferably, each pair of slide rods is set together and symmetrically fixed on one of the inclined through slots, and the slider and slide rod are arranged in a one-to-one correspondence.

[0012] Preferably, the transverse threaded cylinder and the insertion ring are arranged perpendicular to each other.

[0013] Compared with the prior art, the conical head for bolted ball joint space frame of this utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting a reinforcing component, after the cone head body is assembled to the bolt ball by high-strength bolts, the insertion ring fixedly set on the top surface of the mounting ring can be inserted into the interior of the external steel pipe. Holes can be opened on the outer circumferential surface of the end of the external steel pipe. After aligning the positioning hole on the outer circumferential surface of the insertion ring with the hole on the steel pipe, the reinforcing bolt can pass through the hole and the positioning hole in sequence and be rotated and assembled into the transverse threaded cylinder on the inner wall of the curved surface of the insertion ring. The insertion ring and the external steel pipe are reinforced, and the connection between the cone head body and the external steel pipe is more stable.

[0015] 2. In this utility model, by setting a limiting component, by pulling the support block upward outside the inclined through groove, the slider fixedly set on the side of the support block can slide upward on the slide rod to cooperate with the lifting and lowering of the support block and help it maintain the angle. The inclined spring fixed between the top surface of the support block and the top surface of the inclined through groove can be compressed by the upwardly moving support block. The transverse limiting block fixed on the end face of the support block moves obliquely upward to avoid the high-strength bolt. After the high-strength bolt passes through the through hole and is installed into the bolt ball, the support block is released, and the deformation of the inclined spring recovers, causing the support block and the transverse limiting block to move downward. The transverse limiting block, which gradually moves downward and approaches the vertical central axis of the cone head body, can press and limit the high-strength bolt. The bolt limiting effect is improved by the pressing method. Attached Figure Description

[0036] Furthermore, the transverse threaded cylinder 302 and the insertion ring 301 are arranged perpendicularly to each other.

[0037] The reinforcement component 3 makes the connection between the cone body 1 and the external steel pipe more stable.

[0038] Example 2

[0039] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, a cone head for a bolt ball joint space frame includes a hollow cone head body 1 and a mounting ring 2 set on the top of the cone head body 1. It also includes a reinforcing component 3 and a limiting component 4 set on the cone head body 1. A through hole 5 is provided at the center of the bottom end of the cone head body 1.

[0040] The reinforcing component 3 includes a plug-in ring 301, a transverse threaded cylinder 302, and a reinforcing bolt 304. The plug-in ring 301 is fixedly mounted on the top surface of the mounting ring 2, and the transverse threaded cylinder 302 is fixedly mounted on the inner curved wall of the plug-in ring 301.

[0041] The limiting component 4 includes a slide rod 401, a slider 402, a support block 403, a lateral limiting block 404, and an oblique spring 405. Two oblique through slots are symmetrically opened on the outer peripheral surface of the cone head body 1. The slide rod 401 is fixedly mounted on the oblique through slots.

[0045] The bolt limiting effect is improved by using the limiting component 4.

[0046] The working principle of this utility model is as follows:

[0047] Pulling the support block 403 upwards outside the inclined through groove causes the slider 402, which is fixedly mounted on the side of the support block 403, to slide upwards on the slider 401, coordinating with the lifting and lowering of the support block 403 and helping it maintain its angle. The inclined spring 405, which is fixed between the top surface of the support block 403 and the top surface of the inclined through groove, is compressed by the upwardly moving support block 403. The transverse limiting block 404, which is fixed to the end face of the support block 403, moves obliquely upwards to avoid the high-strength bolt. After the high-strength bolt passes through the through hole 5 and is installed into the bolt ball, the support block 403 is released, and the deformation of the inclined spring 405 recovers, driving the support block 403 to move upwards. As the transverse limiting block 404 moves downward, it gradually moves closer to the vertical central axis of the cone head body 1. The transverse limiting block 404 presses the limiting high-strength bolt, and the insertion ring 301, which is fixedly set on the top surface of the mounting ring 2, is inserted into the outside steel pipe. A hole is opened on the outer circumferential surface of the end of the outside steel pipe. After the positioning hole 303 on the outer circumferential surface of the insertion ring 301 is aligned with the hole on the steel pipe, the reinforcing bolt 304 passes through the hole and the positioning hole 303 in sequence and is rotated and assembled into the transverse threaded cylinder 302 on the inner wall of the curved surface of the insertion ring 301. The insertion ring 301 and the outside steel pipe are reinforced.
