[0002] Hyperboloid canopy steel - concrete linking node is a kind of special linking node, hyperboloid canopy is a kind of special shape sunshade, the main feature of hyperboloid canopy is that its appearance presents the shape of double curvature, and different bending degrees can also be formed according to demand, this design is not only beautiful and generous, and better visual effect and space feeling can be provided, and therefore the requirement of supporting structure is higher, since the support connecting point on hyperboloid canopy is all curved surface, to reduce the excessive pulling force that linking node generates to the canopy and make the deformation of canopy, support connecting point at canopy and concrete column needs to be set to be rotatable, and to realize different bending degrees according to demand, the distance of two support connecting points needs to be set to change, in prior art, the entire hyperboloid canopy steel - concrete linking node is usually replaced directly, to form the effect of demand, but in actual use, it is found that two support connecting points are disassembled for many times, connection strength is inevitably reduced, canopy is also easily damaged in installation process, and it is time-consuming and laborious, and the connection strength of movable part is not enough by using telescopic connecting rod, therefore a hyperboloid canopy steel - concrete linking node is required, the device can quickly replace the connecting rod of different length under the condition of guaranteeing connection strength.

[0003] In combination with the above reasons, how to quickly replace the connecting rod of different length under the condition of guaranteeing connection strength is the problem considered by the present application. UTILITY MODEL CONTENTS

[0004] In view of the deficiencies in the prior art, a hyperboloid canopy steel - concrete linking node is provided, which can quickly replace the connecting rod of different length under the condition of guaranteeing connection strength.

[0005] To achieve the above purpose, the following technical scheme is provided: a hyperboloid canopy steel - concrete linking node, comprising a first rotating assembly, a connecting assembly, a first fixed assembly, a second fixed assembly and a second rotating assembly, the first rotating assembly and the second rotating assembly are respectively detachably connected to the two ends of the connecting assembly, the first fixed assembly is arranged at the connection between the first rotating assembly and the connecting assembly, the second fixed assembly is arranged at the connection between the second rotating assembly and the connecting assembly, the connecting assembly comprises a connecting rod, one end of the connecting rod towards the first fixed assembly is provided with a first thread, the first fixed assembly comprises a first threaded tube threadedly connected with the connecting rod, one end of the connecting rod towards the second fixed assembly is provided with a second thread, and the second fixed assembly comprises a second threaded tube threadedly connected with the connecting rod;

[0006] When the first fixing assembly is installed on the first rotating assembly and the connecting assembly, the first rotating assembly and the connecting assembly cannot be separated;

[0007] When the second fixing assembly is installed on the first rotating assembly and the connecting assembly, the second rotating assembly and the connecting assembly cannot be separated.

[0008] In summary, the above technical scheme has the following beneficial effects: In the prior art, a connecting rod with telescopic ability is usually used as a support between the first rotating assembly and the second rotating assembly, but the connecting rod with telescopic ability needs to be fixed in length by an additional fixing component to avoid sudden shortening or stretching, but such a fixing component itself has poor reliability and is prone to breakage, which leads to functional failure and safety hazards. In addition, the extended part and the non-extendable part of the connecting rod with telescopic ability overlap, so when the extended part is extended, the non-extendable part is in a hollow state, which leads to low wear resistance and compression resistance, and is prone to breakage or deformation due to insufficient strength, thereby reducing its service life and safety. Therefore, a connecting rod with telescopic ability cannot be used, and a solid connecting rod needs to be used to ensure strength.

[0009] In the utility model, a solid connecting rod is used, and a first thread and a second thread are arranged at both ends of the connecting rod respectively, the connecting strength is ensured through thread connection, thread connection is a widely used detachable fixed connection, which is usually connected by internal and external threads, that is, the first thread and the first threaded pipe cooperate, and the second thread and the second threaded pipe cooperate, which makes the structure relatively simple, easy to manufacture and disassemble, and the close cooperation of the threads can provide stable connection effect. Under correct installation and use conditions, the thread connection can maintain high connection strength and sealing performance, and on this basis, the connecting rod has no excessive other structure, and according to the principle of steel cold hardening, the strength of the thread rolled on the reinforcing steel bar is greatly improved, so that the tensile strength of the straight thread joint is higher than that of the reinforcing steel bar. When the shape of the rain shed needs to be changed, only the connecting rod of different lengths needs to be replaced, so that the purpose of quickly replacing the connecting rod of different lengths while ensuring the connection strength can be achieved.

[0010] In addition, since the connecting rod adopts a thread connection mode, the connection strength at the thread connection place is inevitably reduced, so the first fixing assembly and the second fixing assembly are additionally arranged to increase the connection strength of the two thread connection places. Without removing the first fixing assembly and the second fixing assembly, the connecting rod, the first threaded pipe and the second threaded pipe cannot be separated.

[0011] The utility model discloses a first threaded pipe and second threaded pipe are cooperated to realize the dismounting and fixing, thereby realizing the purpose that different connecting rods can be replaced quickly under the condition of guaranteeing the connecting strength.

[0027] When the second fixed component 4 is installed on the first rotating component 1 and the connecting component 2, the second rotating component 5 and the connecting component 2 cannot be separated;

[0028] In the prior art, the connecting rod 21 with telescopic ability is usually used as the support between the first rotating component 1 and the second rotating component 5, but the connecting rod 21 with telescopic ability needs to be fixed in length by an additional fixing component to avoid sudden shortening or expansion, but such a fixing component itself has poor reliability and is easy to break and cause functional failure, causing safety hazards, in addition, the extended part and the non-extendable part of the connecting rod 21 with telescopic ability will overlap, so when the extended part is extended, the non-extendable part is in a hollow state, which leads to low wear resistance and compression resistance, and is easy to break or deform due to insufficient strength, thereby reducing its service life and safety, therefore, the connecting rod 21 with telescopic ability cannot be used, and a solid connecting rod 21 needs to be used to ensure strength;

[0029] The utility model discloses a solid connecting rod 21 is used, and first thread 22 and second thread are set respectively at both ends of connecting rod 21, and the connecting strength is guaranteed through threaded connection, and threaded connection is a widely used detachable fixed connection, usually by internal thread and external thread threaded connection, that is, the cooperation of first thread 22 and first threaded pipe 11 and the cooperation of second thread and second threaded pipe 51, which makes its structure relatively simple, easy to manufacture and disassemble, and the close cooperation of thread can provide stable connecting effect, under correct installation and use conditions, threaded connection can keep high connecting strength and sealing performance, and on this basis, connecting rod 21 has no too many other structures, can improve the thread strength rolled on the reinforcing steel bar according to the principle of steel cold hardening, thereby making the tensile strength of straight thread joint higher than the tensile strength of reinforcing steel bar, when the shape of canopy needs to be changed, only need to replace the connecting rod 21 of different length, thereby realizing the purpose that connecting rod 21 of different length can be quickly replaced under the condition of guaranteeing connecting strength.

[0030] In addition, because connecting rod 21 adopts threaded connection mode, the connecting strength is inevitably reduced at threaded connection, therefore, first fixed component 3 and second fixed component 4 are additionally arranged to increase the connecting strength of two threaded connections, and connecting rod 21, first threaded pipe 11 and second threaded pipe 51 will not be separated without removing first fixed component 3 and second fixed component 4,

[0031] The utility model discloses a first thread 22 and second thread are set on connecting rod 21, and first threaded pipe 11 and second threaded pipe 51 are cooperated to realize disassembly and fixation, thereby realizing the purpose that connecting rod 21 of different length can be quickly replaced under the condition of guaranteeing connecting strength.

[0032] Further, first threaded pipe 11 is fixedly connected with positioning ring 12, a plurality of tooth grooves 13 are arranged on positioning ring 12, first fixed component 3 includes threaded sleeve 31, moving pipe 32 and positioning tooth 33, positioning tooth 33 is fixedly connected with moving pipe 32, moving pipe 32 is slidably connected with threaded sleeve 31, and threaded sleeve 31 is threadedly connected with first thread 22;

[0033] After threaded sleeve 31 rotates and approaches first threaded pipe 11, threaded sleeve 31 abuts against moving pipe 32, and positioning tooth 33 is inserted into tooth groove 13;

[0034] The tooth groove 13 and the positioning tooth 33 can form a gear lock. When the first threaded pipe 11 needs to be connected with the connecting rod 21, the moving pipe 32 is first inserted into the threaded sleeve 31. The bottom of the threaded sleeve 31 will abut against the moving pipe 32 and drive the moving pipe 32 to move. Then the threaded sleeve 31 continues to rotate and approaches the positioning ring 12. In the process of driving the moving pipe 32 to approach the positioning ring 12, the positioning tooth 33 will be inserted into the tooth groove 13. At this time, the connecting rod 21 cannot rotate in any direction relative to the first threaded pipe 11, so that the accidental rotation of the connecting rod 21 is prevented from disengaging from the first threaded pipe 11, thereby enhancing the connection strength. When the connecting rod 21 needs to be replaced, only the positioning tooth 33 needs to be damaged. The moving pipe 32 and the positioning tooth 33 do not have high strength requirements and can be made of inexpensive materials.

[0035] Further, the threaded sleeve 31 is provided with a bolt rail 34, and the bolt rail 34 is fixedly connected with an elastic abutting piece 35 on the side facing the positioning ring 12. The moving pipe 32 is fixedly connected with a bolt 36.

[0036] After the threaded sleeve 31 rotates and approaches the first threaded pipe 11, the bolt 36 is moved, and the bolt 36 passes through the elastic abutting piece 35 and is fixed in position by the elastic abutting piece 35.

[0037] During the rotation of the threaded sleeve 31, the positioning tooth 33 may be accommodated in the tooth groove 13 although there is a distance. In order to avoid this situation, the bolt rail 34 and the bolt 36 are arranged in cooperation to prevent the positioning tooth 33 from hindering the rotation of the threaded sleeve 31. After the threaded sleeve 31 rotates to a predetermined position, the bolt 36 is pushed to drive the positioning tooth 33 to be inserted into the tooth groove 13. In this process, the bolt 36 can deform the elastic abutting piece 35 by extrusion, so as to smoothly pass through the elastic abutting piece 35, and then the bolt 36 is fixed in position by the combined action of the inner wall of the bolt rail 34 and the elastic abutting piece 35. This process requires the use of a special tool, so it is not safe enough. In addition, the bolt 36 can be pushed in the opposite direction to make the positioning tooth 33 disengage from the tooth groove 13, so that the positioning tooth 33 does not need to be damaged.

[0038] Further, the first fixed assembly 3 further comprises a buffer ring 37, and the buffer ring 37 is provided with a through groove 38 for the positioning tooth 33 to pass through.

[0039] When the threaded sleeve 31 and the moving pipe 32 move relative to each other, a certain distance difference will be generated, so the threaded sleeve 31 cannot abut against the positioning ring 12. In order to prevent the threaded sleeve 31 from rotating excessively, the buffer ring 37 is arranged to control the distance of the movement of the threaded sleeve 31.

[0040] Further, the side edge of the positioning tooth 33 is provided with an insertion groove 331, and the side wall of the through groove 38 is provided with an inclined surface 381 for guiding to the insertion groove 331.

[0041] Since there is a need to destroy the positioning teeth 33, in order to more conveniently destroy the positioning teeth 33, the insertion slot 331 is arranged, and when destroying, only the tool is inserted into the insertion slot 331 to lift the positioning teeth 33 to destroy the positioning teeth 33, and the arrangement of the inclined surface 381 can accurately and quickly guide the tool to be inserted into the insertion slot 331.

[0042] Further, the first fixing assembly 3 further comprises a protective sleeve 39, the protective sleeve 39 is threadedly connected with the connecting rod 21, and the protective sleeve 39 is used for covering the first threaded pipe 11, the positioning teeth 33, the buffer ring 37 and the positioning ring 12.

[0043] Further, the structure of the second rotating assembly 5 is the same as that of the first rotating assembly 1, and the structure of the second fixing assembly 4 is the same as that of the first fixing assembly 3.
