Description

Technical Field

[0001] The utility model relates to the technical field of composite steel pipe connectors, in particular to a composite steel pipe connector. Background Art

[0002] In fields such as industry and construction, in order to make more rational use of material properties, the concept of composite steel pipes has been proposed. By combining materials with different properties, the advantages of various materials can be fully utilized. For example, the high strength of carbon steel and the corrosion resistance of stainless steel are combined to produce composite steel pipes that can withstand higher pressures and resist erosion in corrosive environments.

[0003] In daily life, stainless steel is used as a transmission pipe for some media due to its good corrosion fatigue resistance and pitting corrosion resistance. During the transmission process of stainless steel pipes, some fixings are required to connect the two ends of the stainless steel pipes. However, the existing fixings are complex in structure and cannot be quickly connected and disassembled. At the same time, after the connection is made, the flow rate of the medium in the stainless steel pipe cannot be well controlled.

[0004] The existing patent (publication number: CN211083196U) is a stainless steel pipe fixing device. First, the stainless steel pipe is placed in the placement groove on the connecting ring, and the locking bolt is screwed into the locking threaded hole. The locking bolt applies an axial clamping force to the stainless steel pipe to fix the stainless steel pipe. When the stainless steel pipe needs to be removed, only the locking bolt needs to be unscrewed to achieve a quick connection of the stainless steel pipe. When the pipeline is connected, the handwheel is turned to drive the stud to move up and down, and the fixing seat on the stud drives the adjustment plate to slide in the inlet channel, thereby changing the cross-sectional size of the medium flowing out of the outlet slot, thereby controlling the size of the medium flow in the fixing device.

[0005] In response to the above problems, the existing patent provides a solution. The existing composite steel pipe connector usually requires the use of a secondary pipe during use, but it is inconvenient to adjust the angle of the secondary pipe, which causes the installers to spend more time adjusting the relative position of the secondary pipe and the main composite steel pipe connector during the on-site installation process, affecting their processing efficiency. Moreover, the long-term use of the fixing parts and the steel pipes leads to reduced durability of the connection parts of the fixing parts, affecting the long-term stability of the pipeline system.

[0006] Therefore, a composite steel pipe connector is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , this utility model provides a technical solution:

[0028] A composite steel pipe connector includes a support base 1, the interior of the support base 1 is connected to a connecting pipe 2, the top and bottom of the connecting pipe 2 are fixedly connected to flanges 3, an auxiliary component 4 is provided on the top of the support base 1, the auxiliary component 4 includes a first fixing block 401 fixedly connected to the outside of the support base 1, and adjustment components 5 are provided on both sides of the support base 1;

[0029] The adjustment assembly 5 includes a first adjustment block 501 bolted to the outside of the support seat 1, a limiting groove 502 is provided inside the first adjustment block 501, a positioning rod 503 is fixedly connected to the inside of the limiting groove 502, a limiting ring 504 is fixedly connected to the outside of the first adjustment block 501, a second adjustment block 505 is rotatably connected to the outside of the first adjustment block 501, a positioning block 506 is fixedly connected to the inside of the second adjustment block 505, the inner side of the positioning block 506 is rotatably connected to the outer side of the positioning rod 503, a groove 507 is provided on the inner side of the second adjustment block 505, the inner side of the groove 507 is rotatably connected to the outer side of the limiting ring 504, a fixing seat 508 is fixedly connected to the outside of the fixing seat 508, and a top plate 509 is bolted to the outside.

[0030] In this embodiment: by rotating the second adjusting block 505, due to the rotational connection between the second adjusting block 505 and the first adjusting block 501 through the positioning rod 503 and the positioning block 506 and the cooperation between the limit ring 504 and the groove 507, the second adjusting block 505 can be flexibly rotated relative to the first adjusting block 501, and then, the auxiliary pipe can be further fixed and supported by the top plate 509 bolted to the outside of the fixing seat 508. Compared with the existing composite steel pipe connector, the angle and position of the auxiliary pipe can be flexibly adjusted, which improves the adaptability of the composite steel pipe connector in different installation environments, reduces the installation difficulty and workload, and improves the installation efficiency.

[0031] Specifically, such as Figure 3 As shown, the interior of the first fixing block 401 is rotatably connected to a support rod 402 , and the outer side of the first fixing block 401 is plugged with a fixing piece 403 .

[0032] Specifically, such as Figure 3 As shown, the outer side of the connecting pipe 2 is fixedly connected with a second fixing block 404 , the inner side of the second fixing block 404 is rotatably connected to the top of the support rod 402 , and the outer side of the second fixing block 404 is plugged with a limiting rod 405 .

[0033] Specifically, such as Figure 3 As shown, a reinforcement rod 406 is fixedly connected to the outer side of the connecting pipe 2 , and the inner side of the reinforcement rod 406 is bolted to the outer side of the support rod 402 .

[0034] In this embodiment: the support seat 1 and the connecting pipe 2 are tightly connected by the first fixed block 401, the support rod 402, the fixing piece 403, the second fixed block 404, the limiting rod 405 and the reinforcing rod 406. At the same time, the connection between the second fixed block 404 and the support rod 402 and the limiting effect of the limiting rod 405 enable the support rod 402 to play a certain supporting and positioning role on the connecting pipe 2 during the rotation process. On the other hand, the bolting of the reinforcing rod 406 further enhances the connection strength between the support rod 402 and the connecting pipe 2, thereby strengthening the connection relationship between the connecting pipe 2 and the support seat 1. Compared with the existing composite steel pipe connector, it can reduce the possibility of loosening or deformation of the connection due to external force during use, and improve the stability of the entire composite steel pipe connector structure.

[0035] Specifically, such as Figure 5 As shown, the outer side of the top plate 509 is threadedly connected to the adjusting rod 6 , the outer side of the adjusting rod 6 is fixedly connected to the auxiliary block 7 , and the outer side of the auxiliary block 7 is clamped with the auxiliary rod 8 .

[0036] Specifically, such as Figure 4 As shown, a placement groove 9 is opened inside the support seat 1, and a shock-absorbing pad 10 is bolted inside the placement groove 9. The shock-absorbing pad 10 is located on the outside of the connecting pipe 2 and is made of rubber.

[0037] In this embodiment: by setting the adjusting rod 6, the auxiliary block 7 and the auxiliary rod 8, when the auxiliary pipe needs to be further fixed, the auxiliary rod 8 can be rotated. Since the auxiliary block 7 is clamped on the outer side of the auxiliary rod 8, and the auxiliary block 7 is fixedly connected to the adjusting rod 6, and the adjusting rod 6 is threadedly connected to the top plate 509, rotating the auxiliary rod 8 will drive the auxiliary block 7 and the adjusting rod 6 to move. The auxiliary rod 8 can limit the moving distance of the adjusting rod 6, thereby achieving more precise adjustment and fixation of the auxiliary pipe position. By setting the placement groove 9 and the shock-absorbing pad 10, during the operation of the pipeline system, when the connecting pipe 2 is vibrated, the shock-absorbing pad 10 will absorb the vibration energy. Because the shock-absorbing pad 10 is located on the outside of the connecting pipe 2 and is arranged in the placement groove 9 inside the support seat 1, it can be in close contact with the connecting pipe 2, thereby effectively buffering the vibration of the connecting pipe 2.

[0038] Specifically, such as Figure 5 As shown, the outer side of the first adjustment block 501 is fixedly connected to the reinforcement block 11 , the outer side of the reinforcement block 11 is rotatably connected to the threaded rod 12 , and the inner side of the threaded rod 12 is threadedly connected to the outer side of the support base 1 .

[0039] Specifically, such as Figure 1 、 Figure 2 As shown, the top and bottom of the connecting pipe 2 are both covered with sealing sleeves 13, and the sealing sleeves 13 are made of rubber.

[0040] In this embodiment: by setting a reinforcement block 11 and a threaded rod 12, when it is necessary to fix the overall position of the second adjustment block 505, the threaded rod 12 connected to the reinforcement block 11 can be rotated. Since the threaded rod 12 is threadedly connected to the outer side of the support seat 1, rotating the threaded rod 12 will cause the first adjustment block 501 to move inside the support seat 1, thereby driving the second adjustment block 505 to move, thereby further fixing the position of the auxiliary pipe. By setting a sealing sleeve 13, during the pipeline connection process, the sealing sleeve 13 fits tightly to the top and bottom of the connecting pipe 2. When the connecting pipe 2 is connected to other components, the sealing sleeve 13 can fill the tiny gap in the connection part to prevent fluid leakage.

[0041] Working principle: When using the composite steel pipe connector, first place the auxiliary pipe to be installed inside the fixing seat 508, and then rotate the auxiliary rod 8. Since the auxiliary block 7 is clamped on the outer side of the auxiliary rod 8, the auxiliary block 7 is fixedly connected to the adjusting rod 6, and the adjusting rod 6 is threadedly connected to the top plate 509. Rotating the auxiliary rod 8 will drive the auxiliary block 7 and the adjusting rod 6 to move. The auxiliary rod 8 can limit the moving distance of the adjusting rod 6, thereby achieving more precise adjustment and fixation of the auxiliary pipe position. When it is necessary to make a finer adjustment to the position of the auxiliary pipe, first rotate the second adjusting block 505. Since the second adjusting block 505 and the first adjusting block 501 are rotatably connected through the positioning rod 503 and the positioning block 506 and the cooperation of the limit ring 504 and the groove 507, the second adjusting block 505 can be flexibly rotated relative to the first adjusting block 501. Then, the auxiliary pipe can be further fixed and supported by the top plate 509 bolted to the outer side of the fixing seat 508. The support rod 402, the fixing piece 403, the second fixing block 404, the limiting rod 405 and the reinforcing rod 406 closely connect the support seat 1 with the connecting pipe 2. At the same time, the connection between the second fixing block 404 and the support rod 402 and the limiting effect of the limiting rod 405 enable the support rod 402 to play a certain supporting and positioning role on the connecting pipe 2 during the rotation process. On the other hand, the bolting of the reinforcing rod 406 further enhances the connection strength between the support rod 402 and the connecting pipe 2, thereby strengthening the connection relationship between the connecting pipe 2 and the support seat 1, thereby solving the problem that the existing composite steel pipe connector usually requires the use of a secondary pipe during use, but it is not convenient to adjust the angle of the secondary pipe, resulting in the installation workers having to spend more time adjusting the relative position of the secondary pipe and the main composite steel pipe connector during the on-site installation process, affecting their processing efficiency. Moreover, the long-term use of the fixing piece and the steel pipe leads to reduced durability of the connection part of the fixing piece, affecting the long-term stability of the pipeline system.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
