DETAILED DESCRIPTION
[0021] like Figures 1 to 5As shown, the pre-buried construction device for water and electricity pipelines in assembled buildings of the present invention comprises a fixing box 1, in which a fixing device 3 is installed, and there are multiple fixing devices 3. An arc groove 10 is opened on the upper part of the fixing box 1, and there are multiple arc grooves 10. The arc grooves 10 are evenly arranged vertically. One end of the fixing device 3 is located in the fixing box 1, and the other end of the fixing device 3 extends the arc groove 10 and is slidably connected to the arc groove 10. The fixing device 3 comprises: a movable block 33, an extension rod 31, an arc clamp 32 and a retractable clamp 13. The arc clamp 32 is hinged to the bottom end of the extension rod 31. The lower end of the arc clamp 32 is hinged to the movable block 33, and the movable block 33 is in an inward state. The lower end of the movable block 33 is hinged to the retractable clamp 13, and there are two retractable clamps 13 arranged opposite to each other. The inner side of the contraction clamp 13 is connected to a second spring 14. There are two contraction clamps 13. A fixing plate 16 is connected between the two contraction clamps 13. The fixing plate 16 is made of a soft material and is integrally arranged. Figure 5 As shown, the arc clamp 32 is connected to the ratchet 17 at the hinged joint with the movable block 33, and the movable block 33 is fixedly connected to the ratchet 17. The central axis of the ratchet 17 is fixedly connected to the connecting rod 18, and the connecting rod 18 is hinged with a retaining plate 19. A first spring 20 is connected between the connecting rod 18 and the retaining plate 19. The other end of the retaining plate 19 is located above the teeth of the ratchet 17, and the inclined surface of the teeth of the ratchet 17 is in a clockwise direction. The retaining plate 19 is in conflict with one side of the tooth plane of the ratchet 17. A torsion spring 21 is connected between the arc clamp 32 and the movable block 33. The extension rod 31 is slidably connected to the arc groove 10, and the arc clamp 32 is located at the lower end of the extension rod 31 and is hinged to the extension rod 31. The fixed box 1 is provided with outlet holes 15 all around, and a cover plate 2 is connected above the outlet hole 15. The cover plate 2 is wrinkled, and the side of the cover plate 2 close to the outlet hole 15 is sticky. The top of the fixing box 1 is provided with a fixing groove 4, and there are multiple fixing grooves 4 that are evenly arranged on both sides of the arc groove 10, and a protrusion 6 is connected to one side of the fixing groove 4. The two sides of the extension rod 31 are hinged with arc hooks 5, and the arc hooks 5 can hook the protrusion 6. The extension rod 31 is connected to an adjustment device 9 for clamping the extension rod. The fixing box 1 is hinged with support rods 7 around, and the support rods 7 are plugged with cone heads 11, and wedge blocks 12 are connected to both sides of the cone head 11.
[0022] The working principle of the above scheme is as follows: the fixing box 1 is placed on the pipe, and the position of the fixing device 3 on the sliding groove 93 is adjusted according to the bending degree of the pipe, so that the fixing device 3 is aligned with the pipe. After determining the position of the fixing device 3, the arc hook 5 is rotated so that the arc hook 5 is rotated into the fixing groove 4 and hooked with the protrusion 6, so that the fixing device 3 does not slide. At this time, the extension rod 31 is pressed, and when the fixing plate contacts the pipe, the fixing plate drives the movable block 33 to retract. At this time, the ratchet rotates in the direction of rotation of the movable block 33, and the force on the abutment plate no longer conflicts with the teeth of the ratchet 17. When the ratchet 17 stops rotating, the abutment plate conflicts with the teeth of the ratchet 17 again. At this time, the fixing plate 16 presses and fixes the bent part of the pipe, and the movable block 33 retracts to clamp and fix the pipe. When the diameter of the pipe is larger than that of an ordinary pipe, the fixing plate 16 presses the pipe, so that the shrink clamp 13 opens to increase the length of the fixing plate 16, thereby pressing the pipe. At the same time, the second spring 14 connected in the contraction clamp 13 can also increase the length of the fixing plate 16 while maintaining the tightening force. At this time, the extension rod 31 is clamped by the adjustment device 9 so that the extension rod 31 no longer moves. After the pipe is fixed, the cover plate 2 is pressed so that the cover plate 2 covers the gap between the pipe and the outlet hole 15 to prevent cement from entering the fixing box 1. At this time, the cone head 11 is hit with external force so that the cone head 11 penetrates into the concrete. When the pouring is completed, the fixing box 1 is pulled out again, and the cone head 11 is separated from the support rod 7. At this time, the torsion spring 21 is no longer subjected to force to reset the movable block 33.
[0023] The beneficial effects of the above scheme are as follows: the fixing device 3 slides in multiple arc grooves 10, so that pipes with different bending degrees can also be fixed; the fixing grooves 4 opened on both sides of the arc groove 10 can fix the fixing device 3 when it is located at different directions of the arc groove 10, preventing the fixing device 3 from being displaced; the pipe can be pressed and fixed by the fixing plate 16, and then the fixing plate 16 is pulled by the shrinking clamp 13 to increase the pressure of the fixing plate 16; at the same time, the shrinking clamp 13 increases the length of the fixing plate 16 when facing a pipe larger than an ordinary pipe, thereby increasing the adaptability of the fixing plate 16.
[0024] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the movable block 33 is connected with a close-fitting component 8, and the close-fitting component 8 includes: an arc block 81, a telescopic rod 84, a third spring 83 and a convex circle 82. The arc block 81 is located inside the movable block 33, and the arc block 81 is made of a soft material. The arc block 81 is hollow inside, and the telescopic rod 84 is located inside the arc block 81. The telescopic length near the middle of the arc block 81 is greater than the length of the telescopic rod 84 on both sides of the arc block 81. The top of the telescopic rod 84 is connected to the convex circle 82, and the third spring 83 is located between the convex circle 82 and the telescopic rod 84.
[0025] The working principle of the above scheme is: when the movable block 33 is retracted, the pipe contacts the close-fitting component 8. At this time, the telescopic rod 84 is forced to retract, so that the arc block 81 is close to the pipe, and the clamping function is realized at the same time.
[0026] The beneficial effect of the above solution is that the tube can be squeezed by the close fitting component 8, thereby increasing the stability of the tube.
[0027] In one embodiment of the present invention, Figures 1 to 4 As shown, the upper part of the extension rod 31 is connected with an adjustment device 9, and the adjustment device 9 includes: a rack 92, a fourth spring 97, a fixed shell 91 and a clamping component. The rack 92 is located on one side of the extension rod 31, and the teeth of the rack 92 are wedge-shaped, and the side of the teeth away from the fixed box 1 is an inclined surface. The fixed shell 91 is located on the upper part of the fixed box 1, and the interior of the fixed shell 91 is hollow. The extension rod 31 passes through the fixed shell 91, and the fourth spring 97 is located in the fixed shell 91 and connected to the extension rod 31. The bottom end of the fourth spring 97 contacts the fixed box 1, and the upper end of the fourth spring 97 contacts the inner side of the fixed shell 91. The clamping component includes: a clamping block 96, a fifth spring 94 and a lever 95. The fixed shell 91 is connected with a sliding groove 93, and one end of the clamping block 96 is located in the sliding groove 93 and the other end extends out of the sliding groove 93, and the clamping block 96 can slide in the sliding groove 93. The block 96 is wedge-shaped, and the side of the block 96 away from the fixed box 1 is an inclined surface. The fifth spring 94 is connected to the inner wall of the sliding groove 93 at one end and to the block 96 at the other end. The lever 95 is connected to the block 96 at one end and passes through the fixed box 1 at the other end.
[0028] The working principle of the above scheme is as follows: when the extension rod 31 is pressed downward, the fourth spring is compressed and contracted. At this time, the inclined surface of the teeth of the rack 92 contacts the inclined surface of the block 96. The block 96 is forced to retract into the sliding groove 93. When the extension rod 31 is no longer pressed downward, the fifth spring 94 rebounds, the block 96 extends out of the sliding groove 93, and the plane of the block 96 contacts the plane of the teeth of the rack 92, so that the extension rod 31 does not move. When the extension rod 31 is to be moved upward, the lever 95 is moved to retract the block 96 into the sliding groove 93. The fourth spring is no longer compressed and rebounds to reset the extension rod 31.
[0029] The beneficial effects of the above scheme are as follows: the extension rod 31 can be fixed at different heights by the adjusting device 9, so that the extension rod 31 can adapt to pipes of different heights; the extension rod 31 can be quickly reset by the lever 95 and the fourth spring. Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and details without departing from the scope defined by the claims of the present invention.
