Description
Technical Field
[0001] The utility model belongs to the technical field of tetrafluoro pipe reinforcement, and particularly relates to a steel-lined tetrafluoro pipe with a connection reinforcement mechanism. Background Technique
[0002] The steel-lined tetrafluoro pipe is a special pipe structure. Its inner wall is lined with tetrafluoro (polytetrafluoroethylene) material, and its outer wall is reinforced and protected with steel.
[0003] Most of the existing devices for connecting and reinforcing steel-lined tetrafluoro pipes add a connecting rod on the outer surface of the flange. Through the fit of the sliding groove at the rear end of the connecting rod and the connecting rod, the flange is reinforced. If there is external force interference in this reinforcement method, it will cause the device to move. Also, because there is no relevant device at the rear end of the connecting rod to fix the fitting position, the connecting rod will slide out of the sliding groove, thus losing the reinforcement connection effect. Therefore, we propose a steel-lined tetrafluoro pipe with a connection reinforcement mechanism. Content of the Utility Model
[0004] The purpose of the utility model is to provide a steel-lined tetrafluoro pipe with a connection reinforcement mechanism. By setting a buckle, specifically, when the top of the fourth fixing block is level with the top of the first slider, the buckle is pulled upward, and the loop on the buckle is sleeved on the U-shaped block. Even if there is external force interference, the connection between the buckle and the U-shaped block keeps the fixing device immovable, strengthening the stability of the fixing component and solving the problem of unstable connection and reinforcement area in the existing technology.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a steel-lined tetrafluoro pipe with a connection reinforcement mechanism, including an annular connection block. The inner surface of the annular connection block is fixedly connected with a steel-lined tetrafluoro pipe. The outer surface of the annular connection block is fixedly connected with a limiting block. On the left side of the steel-lined tetrafluoro pipe on the right side, a flange is fixedly connected. Three fixing components are arranged on the left side of the flange. The three fixing components are arranged in a circumferential array with the annular connection block as the center. The parts included in the three fixing components are the same. By setting three fixing components, the connection of the steel-lined tetrafluoro pipe is made more firm, reducing the influence caused by the shaking of the pipe;
[0007] The fixing assembly includes a fixing block four, the top of which is fixedly connected to a U-shaped block, a fixing groove one is opened on the right side of the fixing block four, and a rack is fixedly connected to the inner wall of the fixing groove one, and three sliders one are arranged on the outer surface of the annular connecting block, and the three sliders one are arranged in a circular array with the annular connecting block as the center, and the parts contained in the three sliders one are the same, and the tops of the three sliders one are fixedly connected to buckles, and the corresponding sides of the three sliders one are fixedly connected to handrails, and three fixing blocks one are arranged on the outer surface of the annular connecting block, and the parts contained in the three fixing blocks one are the same, and the buckles are arranged, specifically, the top of the fixing block four is level with the top of the slider one, and the buckle is pushed upward to cover the ring on the buckle with the U-shaped block. Even if there is interference from external force, the connection between the buckle and the U-shaped block makes the fixing device unmoved, thereby strengthening the stability of the fixing assembly.
[0008] Furthermore, a fixing groove 2 is provided inside the slider 1, and a sliding groove 1 is provided on the front and back sides of the inner wall of the fixing groove 2. A rotating shaft 2 is slidably connected to the inner wall of the sliding groove 1, a circular hole is provided inside the fixing block 1, a through hole 1 is provided inside the limiting block, a square groove 1 is provided on the inner wall of the through hole 1, a telescopic cylinder is fixedly connected to the bottom of the inner wall of the square groove 1, a telescopic rod is slidably connected to the top of the telescopic cylinder, a semicircular fixing block is fixedly connected to the top of the telescopic rod, and a spring is sleeved on the outer surface of the telescopic cylinder. By setting the telescopic cylinder, the spring will be compressed when the handrail passes through the semicircular fixing block. After the handrail completely passes through the semicircular fixing block, the semicircular fixing block will pop out again to stabilize the handrail in the limiting block, making it difficult for the handrail to move, thereby ensuring the stability of the steel-lined polytetrafluoroethylene pipe docking and reducing the impact of the handrail driving the movement of the slider 1.
[0009] Furthermore, a rotation groove is opened on the left side of the slider 1, and the inner wall of the rotation groove is rotatably connected to a rotating shaft 1, and a gear is fixedly connected to the center of the outer surface of the rotating shaft 1. By setting the gear, the slider 4 can move up and down, and will not affect the docking of the steel-lined polytetrafluoroethylene pipe.
[0010] Furthermore, a connecting shaft is fixedly connected to the front side of the rotating shaft 1, a cross-shaped through hole is provided inside the connecting shaft, a round handle is fixedly connected to the front side of the connecting shaft, and a fixing block 2 is fixedly connected to the front and back sides of the slider 1. By providing the cross-shaped through hole, it is ensured that the pin can dock with the cross-shaped through hole, so that the gear can stop and the slider 4 can perform the fixing work normally.
[0011] Further, a base is fixedly connected to the top of the second fixing block on the front side. A second square groove is provided inside the base. A third sliding groove is provided on the inner wall of the second square groove. A third slider is slidably connected to the inner wall of the third sliding groove.

[0012] Further, the outer surface of the gear is rotatably connected to the inner wall of the rotating groove. The bottom of the first slider is slidably connected to the outer surface. The right side of the fourth fixing block is slidably connected to the left side of the first slider. The bottom of the spring is fixedly connected to the bottom inner wall of the first square groove. The top of the spring is fixedly connected to the bottom of the semi-circular fixing block. The top and bottom of the rack are fixedly connected to the inner walls of the second fixing grooves. The inner wall of the round hole is fixedly connected to the outer surface of the second rotating shaft. The outer surface of the first fixing block is slidably connected to the inner wall of the second fixing groove. By providing the sliding connection between the first fixing block and the second fixing groove, it is ensured that the first slider moves in the horizontal direction.
[0013] The utility model has the following beneficial effects:
[0014] 1. By providing a buckle in the utility model, specifically, when the top of the fourth fixing block is flush with the top of the first slider, the buckle is toggled upward, and the loop on the buckle is sleeved on the U-shaped block. Even if there is external interference, the connection between the buckle and the U-shaped block keeps the fixing device immovable, strengthening the stability of the fixing assembly.
[0015] 2. By providing a telescopic cylinder in the utility model, specifically, when the armrest passes through the semi-circular fixing block, the spring will be compressed. After the armrest completely passes through the semi-circular fixing block, the semi-circular fixing block will pop out again, stabilizing the armrest within the limiting block, making the armrest not easy to move, thereby ensuring the stability of the butt joint of the steel-lined PTFE pipe and reducing the influence caused by the armrest driving the first slider to move.
[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the utility model.
[0027] Please refer to Figures 1-6 As shown, the utility model is a steel-lined PTFE pipe with a connection reinforcement mechanism, including a ring connection block 1.

By setting the three fixing components 2, the connection of the steel-lined PTFE pipe is made more firm, reducing the influence caused by the shaking of the pipe;
[0028] The fixing assembly 2 includes a fixing block 21, a U-shaped block 23 is fixedly connected to the top of the fixing block 21, a fixing groove 1 is opened on the right side of the fixing block 21, a rack 210 is fixedly connected to the inner wall of the fixing groove 1, three sliders 11 are arranged on the outer surface of the annular connecting block 1, the three sliders 11 are arranged in a circular array with the annular connecting block 1 as the center, the three sliders 11 contain the same parts, a buckle 22 is fixedly connected to the top of the three sliders 11, and a handrail 12 is fixedly connected to the corresponding side of the three sliders 11, and three fixing blocks 13 are arranged on the outer surface of the annular connecting block 1, and the three fixing blocks 13 contain the same parts. By setting the buckle 22, specifically when the top of the fixing block 21 is level with the top of the slider 11, the buckle 22 is pushed upward to cover the ring on the buckle 22 around the U-shaped block 23, even if there is interference from external force, the connection between the buckle 22 and the U-shaped block 23 makes the fixing device unmoved, thereby strengthening the stability of the fixing assembly 2.

[0034] A specific application of this embodiment is as follows: First, the staff member pries up the buckle 22 upward to disconnect the connection between the buckle 22 and the U-shaped block 23. Then, the circular handle 15 is rotated clockwise, causing the connecting shaft 14 to rotate and drive the first rotating shaft 110 to rotate together. Through the interaction of the gear 111 and the rack 210, the fourth fixing block 21 rises, thereby driving the third fixing block 17 and the second slider 171 to slide upward in the second chute. And the staff member can visually observe the rising situation of the fourth fixing block 21. When the bottom end of the fourth fixing block 21 is level with the top end of the flange 30, the rotation of the circular handle 15 can be stopped. Then, the third slider 190 is pushed to drive the bolt 191 to move, and the base 19 is pushed into the cruciform through-hole to fix the connecting shaft 14, making the fourth fixing block 21 hover. Then, by moving the handrail 12 to the right, the first fixing block 13 drives the first slider 11 to move, and the fixing assembly 2 is moved to the left side of the first fixing block 13 until the handrail 12 touches the semi-circular fixing block 182. Continuing to move, it starts to pass through the semi-circular fixing block 182, squeezing the semi-circular fixing block 182 and simultaneously compressing the spring 183 until the handrail 12 abuts against the inner wall of the first through-hole in the limiting block 18. At this time, the handrail 12 completely passes through the semi-circular fixing block 182, and the semi-circular fixing block 182 pops up again after the handrail 12 completely passes through. Then, the movement of the handrail 12 is stopped, and the steel-lined PTFE pipe to be connected is inserted from the left side of the device. After insertion, the staff member first docks the flange 30, and then moves the handrail 12 in the reverse direction, making the fourth fixing block 21 located on the left side of the docked flange 30. The third slider 190 is pushed in the reverse direction to push the bolt 191 out of the second through-hole, enabling the fourth fixing block 21 to move. Then, the circular handle 15 is rotated counterclockwise to make the gear 111 rotate in the reverse direction, lowering the fourth fixing block 21. After the fourth fixing block 21 completely descends, the buckle 22 and the U-shaped block 23 are buckled again. Then, the third slider 190 is pushed in the reverse direction again to make the bolt 191 re-enter the second through-hole, thereby clamping the flange 30 by the fourth fixing block 21.
